摘要： Certain aspects of the present disclosure relate to a technique for managing contention-based uplink data transmissions. According to certain aspects, a base station may allocate a common contention-based resource to a plurality of user equipment (UEs). The plurality of UEs may utilize the contention-based resource to transmit uplink data without prior scheduling, which may result in transmission collisions. Certain aspects of the present disclosure provide a mechanism for determining which UE sent an uplink transmissions based on one or more transmission parameter signaled to the UEs.

摘要： Systems and methodologies are described that facilitate employing periodic closed loop power control corrections in a wireless communication environment. A periodic power control command can be sent over a downlink to control and/or correct an uplink power level employed by an access terminal. Each periodic power control command can be generated based upon an uplink periodic transmission sent from the access terminal. The periodic power control commands can be communicated via a Physical Downlink Control Channel (PDCCH) or in-band signaling. Moreover, access terminals can be grouped to enhance efficiency of downlink transfer of the periodic power control commands. The periodic power control commands can be halted upon access terminal uplink resources being deallocated. For instance, these resources can be deallocated after an inactivity period of the access terminal. Thereafter, the access terminal can initiate random access (e.g., leveraging open loop mechanisms) to resume periodic power control command transmission.

摘要： A wireless communication network distributes resources for a Physical Downlink Control CHannel (PDCCH) over multiple carriers in accordance with a constraint that limits a number of blind decoding actions required by user equipment (UE). Distribution can entail segregating UE-specific and common search spaces to different monitored carriers. Distribution can entail segregating aggregation levels to different monitored carriers. Distribution can entail segregating a number of decoding candidates for a given aggregation level to different monitored carriers. The distribution can be orthogonal or non-orthogonal, and can be UE-based or per cell-based. The distribution can be static, semi-static or hop with time.

摘要： In accordance with one or more embodiments and corresponding disclosure thereof, various aspects are described in connection with providing shared scheduling request (SR) resources to devices for transmitting SRs. Identifiers related to the shared SR resources can be signaled to the devices along with indications of the shared SR resources in given time durations. Thus, devices can transmit an SR over shared SR resources related to one or more received identifiers for obtaining an uplink grant. This can decrease delay associated with receiving uplink grants since the device need not wait for dedicated SR resources before transmitting the SR. In addition, overhead can be decreased on control channels, as compared to signaling dedicated SR resources and/or uplink grants. Moreover, identifiers related to SR resources can correspond to a grouping of devices, such that a device can transmit over shared SR resources related to a group including the device.
摘要翻译： 根据一个或多个实施例及其对应的公开内容，结合向用于发送SR的设备提供共享调度请求（SR）资源来描述各个方面。 与共享SR资源相关的标识符可以在给定的持续时间内与信号通知给设备以及共享SR资源的指示。 因此，设备可以通过与一个或多个接收到的标识符相关的共享SR资源发送SR以获得上行链路许可。 这可以减少与接收上行链路授权相关联的延迟，因为在发送SR之前设备不需要等待专用SR资源。 此外，与信令专用SR资源和/或上行链路授权相比，控制信道上的开销可以减少。 此外，与SR资源相关的标识符可以对应于设备的分组，使得设备可以通过与包括设备的组相关的共享SR资源进行传输。
