    Abstract: Methods, systems, and devices for wireless communications are described for antenna selection and reporting for multiple-input multiple-output (MIMO) communications. One or more grouping parameters may be provided to a wireless node, which may indicate a subset of antennas that are to be used for MIMO communications, may indicate one or more target nodes for MIMO communications, or combinations thereof. The wireless node may measure one or more channel parameters based on the grouping parameters and determine one or more antenna subsets or target nodes that meet MIMO communication parameters (e.g., an antenna group or target node that will support a certain rank of MIMO communications). The wireless node may report an indication of the identified antenna subsets or target nodes to a control entity for scheduling of MIMO communications.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide a mechanism for a user equipment (UE) to identify an uplink transmit beam to be used for communicating with a base station. In some cases, the uplink transmit beam may be based on a recent uplink (or downlink) transmission or set of allocated resources. A base station may allocate communication resources for a UE. The UE may determine, based on the allocated communication resources, a default transmit beam for communicating with the base station. The UE and base station may (e.g., independently) identify a triggering condition for using the default transmit beam. The UE may transmit an uplink communication to the base station using the default transmit beam based on the triggering condition.

    Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes configuring a relay selection rule; receiving at least one discovery message from each of a plurality of proximity services (ProSe) relay candidates providing access to a network; evaluating the received discovery messages with respect to the relay selection rule; selecting a first ProSe relay candidate from the plurality of ProSe relay candidates based at least in part on the evaluating; and connecting to the network via the first ProSe relay candidate. A method for wireless communication at a ProSe relay candidate includes receiving, from a network, a ProSe Relay Indication (PRI); broadcasting at least one discovery message that includes the PRI; and receiving a relay connection request from a UE based at least in part on a compliance of the at least one discovery message with a relay selection rule of the UE.

    Abstract: A base station may transmit a quasi-collocation (QCL) relationship indication to a user equipment (UE) that indicates different QCL groups (e.g., QCL relationships corresponding to different port groups). The QCL relationship indication may include a tuple of transmission configuration indication (TCI)-states, TCI-states configured with TCI-state-sets, or multiple TCI-states indicated via an extended media access control (MAC) control element (CE). The QCL relationship indication may indicate a QCL relationship between one or more port groups of a first reference signal set and a plurality of port groups associated with a target reference signal. For example, the QCL relationship indication may indicate two QCL groups, where each QCL group includes a QCL relationship between a reference signal resource and a port group associated with a target reference signal. Using QCL group information, the UE may perform channel estimation for demodulating target reference signals, using the QCL antenna port group.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit two or more connection requests prior to expiration of a UE connection response window. In some examples, the UE may re-set a UE connection response window each time the UE transmits a connection request. In some examples, the base station and UE may set their respective connection response windows after the UE transmits connections requests in a set of consecutive transmission opportunities. In some examples, the base station and UE may set their respective connection response windows based at least in part on a first available transmission opportunity. In some examples, the UE may include an indication of a position in a transmission sequence in the connection response, and the base station may set the UE connection response window based at least in part on the indication.
