    Abstract: Methods, systems, and devices for prioritization of channel state information (CSI) processes based on a set of priority rules and a device capability are described. A user equipment (UE) may be capable of supporting multiple communication types such as ultra-reliable low latency communications (URLLC), shortened transmission time interval (sTTI), enhanced mobile broadband (eMBB) priority type, etc. The UE may indicate a CSI update capability that includes a number of CSI processes capable of being updated by the UE. The CSI update capability may be a joint CSI update capability provided for all communication types. Based on the CSI update capability of the UE and the set of priority rules, the UE may prioritize the updating of one or more CSI processes.

    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may precode downlink signals to be transmitted to a user equipment (UE) using a precoding matrix. The precoding matrix may be selected by a UE from a number of precoding matrices (e.g., a codebook) and reported to the base station in a channel state information (CSI) report. As described herein, a base station may support techniques for limiting a number of precoding matrices that a UE may evaluate to identify a preferred precoding matrix to be indicated to the base station. In addition, the techniques described herein allow a base station to dynamically indicate an appropriate set of precoding matrices for the UE to evaluate based on the channel conditions at a given time.

    Abstract: Disclosed embodiments facilitate UE location determination in systems with dense PRS configurations, reduced PRS periodicity, frequency hopping, and involving UE inter-frequency measurements. The techniques may be applied to Bandwidth reduced-Low complexity (BL) UEs, or enhanced Machine Type Communication (eMTC) UEs or Further enhanced MTC (FeMTC) UEs and/or in LTE-M systems. A method on a UE may comprise: receiving a Reference Signal Time Difference (RSTD) measurement request; transmitting, in response to the RSTD measurement request, a dedicated gap request comprising a requested configuration of dedicated gaps; and receiving, in response to the dedicated gap request, a message comprising a dedicated gap configuration. The dedicated gap request may comprise a request for dedicated measurement gaps and the message may comprise a dedicated measurement gap configuration. In some embodiments, the dedicated gap request may comprise a request for dedicated autonomous gaps and the message may comprise a dedicated autonomous gap configuration.
