Abstract:
This disclosure relates to Wi-Fi signaling in conjunction with cellular communication in unlicensed frequency bands for efficient co-existence. According to one embodiment, a cell may be established between a cellular base station and a wireless user equipment device on a frequency channel in an unlicensed frequency band. A cellular communication may be scheduled between the base station and the user equipment device. A Wi-Fi signal may be transmitted on the frequency channel in conjunction with the scheduled cellular communication. The Wi-Fi signal may indicate a length of the scheduled cellular communication using Wi-Fi signaling. The scheduled cellular communication may be performed via the cell.
Abstract:
A pre-allocation grant schedule for communications between a wireless communication device (UE device) and a base station may be conducted according to requests made by the UE device. The UE device may provide information to a base station, requesting the base station to end a previous pre-allocation schedule and/or to start a new pre-allocation schedule. A request for stopping a previous pre-allocation schedule and starting a new pre-allocation schedule may be transmitted at the same time or in subsequent frames, respectively, depending on whether transition is from talk to non-talk mode or non-talk to talk mode. The base station may determine a pre-allocation schedule using the information received from the UE device, and may begin communicating uplink grants to the UE device according to the pre-allocation schedule requested by the UE device. The UE device may in turn may communicate with the base station according to the received uplink grants.
Abstract:
Described herein are systems and methods for carrier aggregation deployment and organization in unlicensed bands. A method may comprise scanning, by a transceiver within a base station, channels in a band of interest, reporting, by the transceiver, signal measurement information to the base station, cell searching, by the transceiver, channels in the band of interest, determining channel information for neighboring each channel, and transmitting, by the transceiver, the channel information to the base station.

Abstract:
Mobile devices, base stations, and/or relay stations may implement methods for decreasing required guard bands while also minimizing Adjacent Channel Leakage Ratio, when multiple mobile devices communicate over different respective adjacent specified frequency bands. For communications over at least one specified frequency band of the different respective adjacent frequency bands, a first bandwidth of uplink communications and/or a second bandwidth of downlink communications may be adjusted to differ from each other, and/or a communications bandwidth within the specified frequency band may be adjusted to be of a first size during a first portion of a specified data transmission period and to be of a second size during a second portion of the specified data transmission period, when at least some of the communications over the specified frequency band take place at frequencies adjacent to frequencies at which at least some of the communications take place over another specified frequency band.
