摘要： Systems and methodologies are described that facilitate selecting an uplink carrier for random access within a wireless environment having multiple carriers. Selection of an uplink carrier for random access can be randomly selected from a set of available uplink carriers. Additionally, the uplink carrier for random access can be selected based upon which uplink carrier is paired with an anchor carrier. Further, the uplink carrier for random access can be identified based upon a bandwidth related to the user equipment (UE). Reference signals can also be employed in order to identify an uplink carrier to perform random access.

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： Methods, systems, devices, and computer program products are disclosed which facilitate the transmission and reception of power headroom reports for component carriers in a multi carrier wireless communication system. A mobile device may determine available power headroom in a multicarrier configuration through a calculation of a maximum transmit power associated with a first component carrier (CC) in a subset of the CCs. The calculation can account for increases in transmit power of other component carriers in the subset by proportionally increasing transmit powers for each of the subset of CCs. A power headroom may be identified for one or more of the CCs based on a result of the calculation, and a power headroom report (PHR) may be generated that includes the power headroom available for the first CC.

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。

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.
