20120088482 | AUTOMATED LAC ASSIGNMENTS FOR ENTERPRISE FEMTOS - In accordance with an example embodiment, there is disclosed herein an apparatus comprising an interface, and processing logic coupled with the interface. The processing logic receives via the interface a list of location area codes detected by an access point associated with a site group to be provisioned with a location area code (LAC). The processing logic removes from a predefined list of location area codes the location area codes detected by the access point. The processing logic selects a LAC from the predefined list for the site group after removing the location area codes detected by the access point. The processing logic provisions the access point with the selected LAC via the interface. | 04-12-2012 |
20120189074 | Diversity for Digital Distributed Antenna Systems - Techniques are provided for a base station to transmit and receive wireless signals via a plurality of remote transceiver stations deployed in a coverage area. The remote transceiver stations are coupled to the base station in order to communicate with wireless mobile devices. A transmission time delay is determined for a message to be transmitted from corresponding remote transceiver stations to a wireless mobile device. Transmission of the message to be wirelessly transmitted from the two or more remote transceiver stations is delayed by a corresponding transmission time delay. The delayed transmissions appear as a resolvable multipath transmission to receivers in the wireless mobile user devices. Techniques are also provided for delaying the processing of uplink transmissions at the base station receiver. Delays associated with downlink or uplink transmissions may also be programmed into individual remote transceiver stations. | 07-26-2012 |
20120257516 | Multi-Receiver Combining for Distributed Antenna Systems with Code Division Multiple Access Radio Frequency Uplink Sources - A distributed antenna system and related methods are provided to reduce interference among wireless mobile devices in a distributed antenna system. A combiner is provided that is configured to be coupled to a plurality of remote transceiver stations deployed in a coverage area and which wirelessly transmit downlink signals to and receive uplink signals from wireless mobile devices. A plurality of input streams that carry uplink signals transmitted by wireless mobile devices are received on individually assigned signal paths from each of the remote transceiver stations. At least one parameter of an input stream received from the one or more of the remote transceiver stations is monitored. A mapping function is determined based on the monitoring. The plurality of input streams are combined based on the mapping function to produce the two or more output streams and the two or more output streams are sent to corresponding receivers in a base station. | 10-11-2012 |
20130142182 | MOBILITY IN MULTI-DEVICE MULTI-HOMED DEPLOYMENTS - Systems and methods for providing identity management and mobility management are disclosed. The management scheme provides mobility in multi-device and multi-homed deployments. A collection of three identities, a device identity, a link layer identity, and a user identity, can be used to provide mobility for a number of devices under different use scenarios. In one embodiment, a method is disclosed for receiving messages from a mobile device at a mobility gateway, the messages including identifiers such as a user identifier, a link layer identifier, and a device identifier where identifiers are stored or retained at the mobility gateway. When a subsequent network attach request is received including one or more identifiers, a reconnection can occur, based on a result of comparing the stored identifiers with the received one or more identifiers. | 06-06-2013 |

20150201451 | Wireless Client Device Roaming Among Clustered Access Points - A controller controls access points (APs) in a network of APs. The controller causes the first AP to establish an Internet Protocol (IP) tunnel with a router connected with a wired network and over which data packets are routed between the wired network and a client device wirelessly connected to the first AP. The controller receives a roam indication that the client device is wirelessly connected with a second AP. In response to the indication, the controller instructs the first AP to maintain the IP tunnel with the router and instructs the second AP to establish an inter-AP tunnel with the first AP in order to route traffic between the wired network and the client device over both the IP tunnel and the inter-AP tunnel. | 07-16-2015 |
20160044516 | Joint Scheduler for Integrated Wi-Fi and LTE-U Wireless Access Point - A wireless access point (AP) configured to operate in accordance with both Wi-Fi and Long-Term Evolution (LTE-U) standards/protocols jointly schedules transmit opportunities for Wi-Fi and LTE-U frames. The AP assigns one of multiple, prioritized, Wi-Fi access categories to each Wi-Fi transmit frame based on a type of data in the transmit frame. The AP also assigns to each LTE-U transmit frame an LTE-U access category prioritized relative to the Wi-Fi access categories. The AP schedules Wi-Fi and LTE-U transmit opportunities for the Wi-Fi transmit frames and the LTE-U transmit frames, respectively, in the shared channel bandwidth based on the prioritized Wi-Fi and LTE-U access categories. | 02-11-2016 |
20160088631 | Frequency Channel Selection by an LTE-U Wireless Access Point Operating in the Presence of Other LTE-U and Wi-Fi Access Points - A Long-Term Evolution-Unlicensed (LTE-U) access point (AP) is configured to operate wirelessly on any of multiple RF channels in an unlicensed frequency band. The AP detects other LTE-U APs and Wi-Fi APs operating on active ones of the multiple channels. The AP determines AP channel statistics for each detected AP. The AP determines, for each active channel, a per-channel metric based on the AP channel statistics. The AP ranks the active channels according to the corresponding per-channel metrics, and selects a best channel on which to transmit in the unlicensed frequency band from among the ranked active channels based on the rankings. | 03-24-2016 |
20160135080 | TRANSMIT NODE DETECTION BY A RECEIVER IN A SHARED ACCESS LTE ENVIRONMENT - Presented herein are mechanisms to reduce collisions in deployments with Wi-Fi and Shared Access LTE (SAC-LTE) equipment as well SAC-LTE equipment from multiple operators. The mechanisms enhance the baseline energy detection mechanism by incorporating methods to decode cross-technology physical layer elements and media access control (MAC) layer elements in the Wi-Fi system to elements in the SAC-LTE system. The methods described improve the detection potential for transmitters, thereby reducing chances of cross-technology collisions. | 05-12-2016 |
20160135185 | METHODS FOR LONG TERM EVOLUTION (LTE) TRANSMISSION BURSTS TO IMPROVE SPECTRAL EFFICIENCY IN UNLICENSED FREQUENCY CHANNELS AND INDOOR SCENARIOS - Modifications to frame/subframe structure are presented herein so that a wirelessdevice can transmit its data within a fraction of a subframe. The device obtains data to be transmitted in an unlicensed spectrum and determines whether an entire subframe is required to completely communicate the data. If the data is small enough to not require the entire subframe, then the device generates a burst transmission to minimize the time period of the subframe used to communicate the data. The device transmits the burst transmission and a parameter indicating the duration of the burst transmission. | 05-12-2016 |
20160135189 | MINIMIZING INTERFERENCE IN WIRELESS COMMUNICATION - A method is provided for minimizing cross-technology interference with data transmissions from a wireless device in a shared spectrum.

The wireless device generates a preamble comprising assistance information related to the transmission burst. The preamble comprises a first preamble portion in the first RAT format and a second preamble portion in a second RAT format. The wireless device transmits the preamble followed by the transmission burst. | 05-12-2016 |
