    Abstract: Certain aspects of the present disclosure relate to reporting difference in timing between cells using multiple connectivity in a wireless network. A first connection served by at least a first cell and a second connection served by at least a second cell to facilitate communicating with at least the first cell and at least the second cell are established. A reporting configuration specifying one or more parameters related to reporting a timing difference between cells is received. A timing difference between at least the first cell and at least the second cell is determined, and the timing difference is reported to at least the first cell over the first connection or to at least the second cell over the second connection. This can facilitate scheduling time aligned operations over the first and second cells, or related cell groups, in multiple connectivity.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) configured with several component carriers (CCs) may select one or more CCs for fast activation. The UE may, in various examples, autonomously select the CCs for fast activation or may receive signaling indicating such CCs. In some cases, the UE may place the selected CCs in a semi-active state by detecting and synchronizing the CCs while refraining from control channel monitoring. In other examples, the UE may identify a set of CCs that may be activated quickly based on channel conditions or that have activation interdependency, such as CCs in a physical uplink control channel (PUCCH) group. The UE may then trigger an activation for one of the selected CCs, determine it is capable of fast activation, and begin monitoring, e.g., for control information, after a reduced delay period based on the fast activation.

    Abstract: Methods, systems, and devices for radio resource management (RRM) measurement and reporting for license assisted access (LAA) cells operating in unlicensed or shared frequency spectrum are described. A user equipment (UE) may receive an RRM measurement configuration including a channel occupancy parameter for measuring neighbor cells of a shared frequency band. The channel occupancy parameter may be used to determine a channel occupancy metric that may be sent to a base station for cell selection. The channel occupancy metric may include an averaged or filtered received signal strength and may be reported for serving cells and/or intra-frequency neighbor cells. A base station may further configure a UE with a discovery reference signals (DRS) measurement timing configuration (DMTC), which may include an extended DMTC search window. The UE may search for DRS transmissions from neighbor cells according to the DMTC.

    Abstract: Methods, systems, and devices are described for signaling device-to-device (D2D) capability information. A user equipment (UE) may determine a frequency band list of frequency bands supported for D2D proximity service communications. Based on the frequency band list, the UE may determine a proximity service record for a frequency band combination parameter, the frequency band combination parameter associated with non-D2D communications. The proximity service record may include a reduced capabilities record for the frequency band combination parameter that indicates reduced capabilities for non-D2D communications when D2D proximity service communications are active.

    Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE) may signal a band-specific measurement gap indication based on the capability of a set of receivers to measure target frequency bands while monitoring a set of component carriers (CCs). The UE may receive a measurement gap configuration for a first component carrier (CC) associated with measuring the target frequency bands accounting for the band-specific measurement gap indication. The UE may then perform a measurement on one or more of the target frequency bands according to the measurement gap configuration while continuing to monitor other configured CCs for downlink messages and transmit uplink control messages during gaps configured for the first CC (e.g., using a different receiver). In some examples the measurement gap configuration message includes configuration options and the UE may select the measurement gap configuration for the first CC from the set of available options.

    Abstract translation: 描述了用于无线通信的方法，系统和设备。 用户设备（UE）可以基于一组接收机在监视一组分量载波（CC）的同时测量目标频带的能力来发信号通知带宽测量间隙指示。 UE可以接收与测量针对带特定测量间隙指示的目标频带相关联的第一分量载波（CC）的测量间隙配置。 然后，UE可以根据测量间隙配置对一个或多个目标频带进行测量，同时继续监视用于下行链路消息的其他配置的CC，并且在针对第一CC配置的间隙期间发送上行链路控制消息（例如，使用不同的 接收器）。 在一些示例中，测量间隙配置消息包括配置选项，并且UE可以从可用选项集合中选择第一CC的测量间隙配置。
