20090180451 | APPARATUS FOR AND METHOD OF COORDINATING TRANSMISSION AND RECEPTION OPPORTUNITIES IN A COMMUNICATIONS DEVICE INCORPORATING MULTIPLE RADIOS - A novel and useful apparatus for and method of coordinating the allocation of transmission and reception availability and/or unavailability periods for use in a communications device incorporating collocated multiple radios. The mechanism provide both centralized and distributed coordination to enable the coordination (e.g., to achieve coexistence) of multiple radio access communication devices (RACDs) collocated in a single device such as a mobile station. A distributed activity coordinator modifies the activity pattern of multiple RACDs. The activity pattern comprises a set of radio access specific modes of operation, (e.g., IEEE 802.16 Normal, Sleep, Scan or Idle modes, 3GPP GSM/EDGE operation mode (PTM, IDLE, Connected, DTM modes), etc.) and a compatible set of wake-up events, such as reception and transmission availability periods. To prevent interference and possible loss of data, a radio access is prevented from transmitting or receiving data packets while another radio access is transmitting or receiving. In the event two or more RATs desire to be active at the same time, the mechanism negotiates an availability pattern between the MS and a corresponding BS to achieve coordination between the RATs. | 07-16-2009 |
20090219849 | APPARATUS FOR AND METHOD OF MULTICAST AND BROADCAST SERVICE (MBS) MACRO-DIVERSITY BASED INFORMATION PROCESSING - A novel and useful apparatus for and method of multicast and broadcast service (MBS) macro-diversity based information processing for use in MBS enabled wireless communication systems. MBS allocations and transmissions from base stations are not coordinated and independent of each other. The characteristics of the MBS signal, such as waveform, modulation, timing and frequency domain, used for transmissions in one or more MBS zones by a base station are uncoordinated and unsynchronized with respect to transmissions in other base stations or MBS zones. They all, however, contain the same information content and relate to the same CID (MCID and/or SA). The MS, using multiple detection techniques, uses time and frequency diversity reception techniques to combine MBS transmissions received from multiple base stations. Base stations and/or the network inform mobile stations of whether or not uncoordinated MBS data transmission is supported on the network via a TLV transmitted during the MBS connection setup process. If supported, mobile stations can receive multiple MBS data signals, combining them to generate a single MBS data output stream. | 09-03-2009 |
20090290555 | Autonomous anonymous association between a mobile station and multiple network elements in a wireless communication system - A novel and useful autonomous association mechanism for use in user equipment (UE) network connections in one or more cellular communications systems. The handover process is optimized by improving the selection of target base stations and optimizing the discontinuity period from the time of disconnection from a serving base station and connection to a target base station and by establishing anonymous bidirectional communications with base stations. The mechanism facilitates multiple cell association in a network unaware manner while preserving single endpoint connectivity. The UE does not need to negotiate for or receive pre-allocated opportunities from the network for making associations with neighboring base stations. Association opportunities are created by the UE autonomously in accordance with UE activity patterns. Association opportunities are used to exchange preliminary information needed for handover between the UE and candidate base stations over the same or a plurality of access technologies. The information includes any parameter that can affect the handover process, e.g., link quality, etc. | 11-26-2009 |
20090291686 | Autonomous connectivity between a mobile station and multiple network elements for minimizing service discontinuities during handovers in a wireless communication system - A novel and useful autonomous connectivity mechanism for use in user equipment (UE) connectivity in one or more cellular communications systems. The handover process is optimized by improving the selection of target base stations and optimizing the discontinuity period from the time of disconnection from a serving base station and connection to a target base station. The mechanism facilitates multiple cell connectivity in a network unaware manner while preserving single endpoint connectivity. The UE does not need to negotiate for or receive pre-allocated opportunities from the network for making neighboring base stations measurements. Measurement opportunities are created by the UE autonomously in accordance with UE activity patterns. Measurement opportunities are used to measure and maintain a candidate target base station list over the same or a plurality of access technologies. The parameter set tracked includes parameters that can be measured without any assistance from the target base station and which can effect the handover process, e.g., link quality, etc. | 11-26-2009 |
20100317374 | APPARATUS FOR AND METHOD OF MANAGING PAGING INTERVAL ACCESS ON A MOBILE STATION - A novel and useful apparatus for and method of managing paging availability of a mobile station in a wireless communications network. The paging availability mechanism of the present invention is able to achieve a substantial amount of power saving by modifying mobile station access to paging intervals. The mechanism dynamically controls access to the wireless network after unavailability periods when mobile stations enter into idle mode. Paging listening intervals for one or more mobile stations are scheduled and synchronized in accordance with the values of one or more parameters or metrics such as link quality. In one embodiment, this is achieved by the mobile station modifying the paging listening intervals access pattern received from the base station. Depending on the one or more parameters or metrics, one or more paging intervals may be skipped thus reducing the power consumption of the mobile station. | 12-16-2010 |

20140171109 | DIFFERENTIATED STATION LOCATION - Embodiments allow a station to determine its location and report the location to a access point or other network entity. The station obtains agreement with an access point, group of access points, or other network entity to provide its location to a designated accuracy level and the access point(s) agree to provide services such as access to a location service, the access point(s) location to a designated positional accuracy, etc. The station measures its position and induces an error in its reported location. The induced error prevents an exact location of the station from being determined by the access point(s) or others, thus preserving the privacy of the station. The location reported by the station may be absolute (e.g., geographic coordinates) or relative to a landmark, location, etc. | 06-19-2014 |

The responding communication station also transmits a response to the ToF measurement request that includes an indication of a time period for an initiating communication station to poll the responding communication station for a ToF result. | 07-24-2014 |
20140214314 | NAVIGATION SYSTEM AND METHOD WITH LOCATION-AWARE ACCURACY AND/OR POWER ADJUSTMENTS - In a navigation system and method, location-aware adjustments may be made to the accuracy and/or power of the navigation system by changing at least one setting of a navigation system receiver in response to at least one characteristic of a navigation route and/or an estimated current position of the receiver. By providing location-aware adjustments, the accuracy may be increased when a higher accuracy is desired and may be decreased when a lower accuracy is sufficient based on the receiver location. A higher accuracy setting may be used, for example, when the estimated current position of a navigation system receiver is within the vicinity of a waypoint along the navigation route and a lower accuracy setting may be used at other times to reduce power consumption. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment. | 07-31-2014 |
20140269549 | WIRELESS STATION AND METHODS FOR TOF POSITIONING USING REVERSE-DIRECTION GRANT - Embodiments of a communication station (STA) and method for time-of-flight (ToF) positioning in a wireless network are generally described herein. In some embodiments, an initiating station may transmit a message M1 carrying a high-throughput control (HTC) field that includes a reverse direction grant (RDG) bit. The RDG indication grants permission to a responding station to send information back to the initiating station. The message M1 may be a timing measurement action frame. An ACK frame may be received from the responding station to acknowledge receipt of the message M1. The ACK frame may optionally carry an HTC field that includes a more PPDU indication to indicate whether a PPDU (e.g., contained in message M2) is to follow the ACK frame. The message M2 may be received from the responding station and may include timing measurement information from a current and/or one or more previous ToF message exchanges. | 09-18-2014 |
