摘要： Aspects of the present disclosure disclose various methods for grouping network resources into precoder resource groups (PRGs) for precoding in MIMO communication. A user equipment (UE) may select a common precoder that may not be restricted to a codebook for precoding the resources in the same PRG. These resource grouping methods provide the UE with the flexibility to select a precoder that is well suited to the channel or bandwidth. Moreover, the base station may reduce downlink signaling because it does not need to signal the precoder choice to the UE. In some examples, the base station may receive PRG based channel state information feedback that facilitates DL precoding. Other aspects, embodiments, and features are also claimed and described.

摘要： Methods, systems, and devices are described for intercepting requests from applications installed on a mobile device. The requests are system calls that establish communication channels for the mobile device. The requests are captured and held from reaching TCP/IP stack of an operating system executing on the mobile device. An intercepted request is aggregated with other intercepted requests. The aggregated requests are bundled together and released to the operating system upon the detection of a triggering event. The capture, holding, and aggregation of requests from applications occur when the mobile device is in a background mode.

摘要： Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in wireless communications are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. A first wireless terminal receives a transmission request and quality of service information from a second wireless terminal corresponding to a connection. The first wireless terminal decides not to receiver yield, determines a request response transmission power level as a function of the received quality of service information, and transmits, at the determined power level, a generated request response signal. By controllably adjusting the transmission power level of a request response, transmitter yielding decisions of lower priority links are impacted, since lower priority links measure and use received power level information corresponding to request responses of higher priority links in their transmitter yielding decisions.

摘要： Methods and apparatus relating to scheduling of air link resources, e.g., traffic segments, in a wireless communications system are described. Various described methods and apparatus are well suited to wireless peer to peer networks in which traffic scheduling is decentralized, e.g. an ad hoc peer to peer network. An individual wireless terminal corresponding to a peer to peer connection which desires to transmit traffic signals make transmitter yielding decisions on a traffic slot by traffic slot basis. The transmitter yielding decision, in some embodiments, includes comparing a link quality estimate corresponding to a higher priority link intending to use the same traffic segment concurrently, to a dynamically generated transmitter yielding threshold. The dynamically generated transmitter yielding threshold is determined based on at least one of: quality of service information corresponding to its own link and historical link quality information corresponding to the higher priority link.

摘要： Aspects of the present disclosure provide methods and apparatus for selecting beamforming parameters for uplink transmissions based on an uplink reference signal. An example method generally includes identifying one or more parameters for beamformed transmission to a transmit receive point (TRP), transmitting a reference signal using beamforming in accordance with the identified parameters, and receiving, from the TRP in response to the reference signal, signaling for adjusting the one or more parameters for one or more subsequent beamformed transmissions.
