Abstract: Techniques and apparatus for a control plane design for bandwidth part (BWP) in new radio (NR) are provided. One technique includes sending information with an indication of a BWP capability of a user equipment (UE) to a base station (BS). A configuration from the BS indicating a set of BWPs available to use for communication is received in response to the indication. Communications are performed on at least one of the set of BWPs. Another technique includes receiving information having an indication of a BWP capability of the UE. A configuration indicating a set of BWPs available for the UE to use for communication is determined. The configuration is sent to the UE.

Abstract: Methods, systems, and devices for increasing physical random access channel (PRACH) capacity using orthogonal cover codes (OCCs) in wireless communications systems are described. A base station may transmit a PRACH configuration that indicates PRACH resources for system access, for example, in a system information block (SIB). A user equipment (UE) may receive the PRACH configuration, and may identify PRACH resources that support OCCs for system access. For example, PRACH configurations with small time domain spacing between PRACH resources may support OCCs. The UE may determine whether to transmit random access (RACH) preamble messages using OCCs in the PRACH resources, and may transmit a RACH preamble message to the base station based on the determination. In some cases, the base station may additionally indicate PRACH resources not configured for OCCs, and the UE may determine which set of resources to transmit in based on one or more parameters.

Abstract: Various aspects of the disclosure relate to delivering a limited amount of system information. For example, the delivery of system information may be divided into broadcasting a limited amount of the system information and using unicast signaling for delivery of the remaining system information. In some aspects, the delivery of a limited amount of system information may involve broadcasting a compressed PLMN ID list (e.g., broadcasting indications of PLMNs). In some aspects, the delivery of a limited amount of system information may involve broadcasting an indication of the version of system information that is valid for a cell. In some aspects, the delivery of a limited amount of system information may involve broadcasting multiple configurations of system information along with indications of each configuration. In some aspects, the delivery of a limited amount of system information may involve broadcasting compressed non-cell-related system information.

Abstract: Flexible beamforming is disclosed in which a base station receives feedback from a user equipment (UE), in which the feedback is related to one or more reference signals transmitted by the base station. The base station will obtain a tilt adjustment based, at least in part, on the feedback and generate an elevation precoding vector based using the feed-back. Using the tilt adjustment and elevation precoding vector, the base station may then perform elevation beamforming with an antenna array of the base station for the UE.

Abstract: A remote UE may transmit, to at least one of a source master network entity or a target master network entity, an indication of a first entity change and a second entity change. The remote UE may receive, from the target master network entity, a measurement configuration during an RRC reestablishment procedure with the target master network entity. The remote UE may transmit, to the target master network entity during the RRC reestablishment procedure, one or more measurements corresponding to the second entity change. The remote UE may receive, from the target master network entity, a dual connectivity configuration based on the transmitted one or more measurements. The dual connectivity configuration may correspond to the first entity change and the second entity change. The remote UE may communicate with the target master network entity and the target secondary network entity based on the dual connectivity configuration.

Abstract: A remote UE may detect one or more relay UEs for a dual connectivity configuration for communication with a first network entity and a second network entity. The dual connectivity configuration may include a primary connection with the first network entity and a secondary connection with the second network entity. The remote UE may receive, from the first network entity, a configuration for establishing the secondary connection via one of the one or more relay UEs based on a decision at the first network entity. The remote UE may establish the secondary connection via the one of the one or more relay UEs for communication with the second network entity. The remote UE may configure one or more second bearers for the secondary connection via the one of the one or more relay UEs. The one or more second bearers may support data transmission via the secondary connection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a message indicating a common pool of resources for a random access channel (RACH). The UE may initiate a random access by transmitting, to the base station, a first RACH preamble in a RACH occasion within a subset of the common pool of resources. The subset is selected based at least in part on a use case that triggered the random access. In some aspects, the UE may transmit an initial RACH preamble and/or a RACH pay load in order to activate the subset. As an alternative, the UE may transmit an initial RACH preamble and/or a RACH payload in order to receive an indication of the subset for the use case that triggered the random access. Numerous other aspects are described.

Abstract: Techniques to incorporate quality of experience (QoE) in mobility management are disclosed. A user equipment (UE) may provide a QoE report to network (e.g., cell) upon detection of a QoE report triggering event (e.g., mobility management, environmental trigger, etc.). The QoE report may comprise information related to QoE metrics such as uplink (UL) latency, UL throughput, UL error rate, downlink (DL) frequency, DL throughput, DL error rate, handover (HO) frequency, beam switch frequency, UE power consumption, etc. The network may take actions such as sending a mobility management command if it is decided that QoE should be restored to the UE.
