20080254820 | Power Control in Wireless Communications Networks During Hand-Over - A method and devices are provided for adapting the transmission power level of a mobile terminal during a handover phase at which the mobile terminal switches from one base station to another. The method provided comprises applying values of operating parameters that characterize both base stations and adapting the transmission power level to an acceptable level at which communications transmitted from the terminal to the second station would be properly received without applying further increase in the transmission power while ensuring that the communications transmitted by the mobile terminal to the second base station, will not cause severe interference to communications exchanged between the second base station and the other terminals communicating therewith. | 10-16-2008 |
20080291831 | Dynamic Management of Wireless Transmissions - There is provided a method and devices for dynamically controlling transmission of communications in a wireless network, which comprises a managing entity and a managed entity that communicate which each other. The managed entity transmits updating information that includes indications of current resources available thereat and/or indications that relate to the reception of communications transmitted by the managing entity. A reporting rate for transmitting the updating information by the managed entity to the managing entity is then determined, and based on the reporting rate that has been determined—modifying, if required, parameters associated with the wireless link extending between the two entities so as to affect changes in the operating conditions at one or both of these entities. | 11-27-2008 |
20090086657 | HYBRID AUTOMATIC REPEAT REQUEST BUFFER FLUSHING MECHANISM - A novel and useful buffer flushing mechanism for use in a communications link. Using hybrid automatic repeat request (HARQ) protocol mechanisms, network elements in a radio access network initiate a HARQ buffer flushing operation. Network elements on both ends of a communication link can autonomously initiate coordinated or uncoordinated flushing of their respective HARQ process buffers based on internal algorithms and/or criteria previously negotiated between the two elements. The flushing operation may be performed on all or a part of the buffer (transmit and/or receive) or on certain complete or partial accumulated information. The criteria may comprise any suitable data including, for example, timeout data, thresholds based on one or more link quality parameters, data measurements exceeding a threshold, etc. which can be used to trigger a buffer flushing event. | 04-02-2009 |
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 |
