Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify that data is available to be transmitted to a user equipment (UE) that is operating in a discontinuous reception (DRX) mode. The base station may configure a plurality of UE–specific reference signals for transmission to the UE, each UE-specific reference signal indicating a UE identifier and an availability of data for the UE. The UE may receive the UE-specific reference signal, and identify that data is available for the UE from the base station. The UE may then transmit a beam recovery signal to the base station that includes an identifier for the transmit beam used by the UE to transmit the beam recovery signal. The base station may transmit, using a beam sweeping configuration, the plurality of UE-specific reference signals.

The first apparatus may transmit, to the UE, information indicating a periodicity at which control information is to be communicated on a control channel through a control-information beam. The first apparatus may communicate, with the UE, the control information on the control channel through the control-information beam at the periodicity. Further, the first apparatus may receive a request to change the active beam, which may indicate a beam index corresponding to a second beam, and the first apparatus may change the active beam to the second beam corresponding to the beam index indicated by the request.

Abstract: A wireless device configured for discontinuous reception (DRX) may and operating in a system that uses directional beamforming may identify a random access time period after awaking from a DRX sleep mode. The device may then transmit a scheduling request during the random access time period. In some cases, the device may transmit the scheduling request using frequency resources also associated with random access transmissions. In other cases, the device may utilize resources that are not associated with random access. The determination of which frequency resources are used may depend on the length of the DRX. That is, if a device has been in a sleep mode for a long time, it may use random access frequency resources that are associated with a more robust transmission configuration.

Abstract translation: 被配置用于不连续接收（DRX）的无线设备可以并且在使用定向波束成形的系统中操作，可以在从DRX睡眠模式唤醒之后识别随机接入时间段。 该设备然后可以在随机访问时间段期间发送调度请求。 在一些情况下，设备可以使用也与随机接入传输相关联的频率资源来传送调度请求。 在其他情况下，设备可以利用与随机访问无关的资源。 确定使用哪些频率资源可能取决于DRX的长度。 也就是说，如果设备长时间处于睡眠模式，则它可以使用与更鲁棒的传输配置相关联的随机接入频率资源。
