Abstract: Certain aspects of the present disclosure provide a method for changing a beam pair utilized by a user equipment (UE) for communicating over a full-duplex frequency channel. The method includes establishing full-duplex communication with a base station (BS) utilizing a first beam pair comprising a first uplink beam and a first downlink beam utilized by the UE for the full-duplex communication. The method also includes transmitting a first signal to the BS, the first signal comprising a request to change the first beam pair. The method also includes receiving, via the first downlink beam, a second signal responsive to the request, the second signal configured to enable the UE to change from the first beam pair to a second beam pair and maintain full-duplex communication with the BS, wherein the second beam pair includes one or more of a second uplink beam or a second downlink beam.

Abstract: Methods, systems, and devices for wireless communications are described. An encoder may utilize a common mother code for encoding control information to each set of control channel resources of a control channel, control channel associated with multiple transmission configuration indication (TCI) states. For example, the common mother code may include utilizing same parameters when constructing the polar code for each set of control channel resources, where the parameters include a block length, a number of information bits, or both. Additionally, rate matching procedures for each control channel resource may differ (e.g., puncturing, shortening, or repetition). Additionally or alternatively, the mother code and rate matching may be determined based on a sum of all available coded bits in each control channel resource and the number of information bits. A decoder may then attempt soft combination of candidates from the different sets of control channel resources to obtain decoded control information.

Abstract: Various aspects described herein relate to techniques for beam discovery and beamforming in wireless communications (e.g., 5th Generation (5G) New Radio (NR)). In an aspect, a method related to signaling for channel state information reference signals (CSI-RSs) in wireless communications is provided. The method includes receiving, by a user equipment (UE), a CSI-RS beam of a set of CSI-RS beams, and the CSI-RS beam includes a change indication message. The method further includes determining, by the UE, whether the set of CSI-RS beams have changed based on a value of the change indication message.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a first user equipment (UE) identifies a trigger condition associated with a first communication link with a base station and establishes a second communication link with a second UE. The UE may transmit a relay request to the second UE based on the trigger condition, wherein the relay request instructs the second UE to relay communications for the first UE. The first UE communicates with the base station via the second communication link. In another example, a base station establishes communication links with a first and second UE. The base station receives a data forwarding request that instructs the base station to use the second UE to relay communications between it and the first UE. The base station communicates with the first UE via the second communication link based at least in part on the relay request.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a first base station using a first antenna array of a set of antenna arrays of the UE. The UE may receive, from the base station, an indication that the UE is to use a second antenna array of the set of antenna arrays to transmit a random access signal. The UE may transmit, to the first base station or a second base station, the random access signal using the second antenna array based on the received indication. The UE may transmit the random access signal to the first base station as part of determining an updated timing advance (TA) value for the second antenna array. The UE may transmit the random access signal to the second base station as a part of initial access or handover.

Abstract: Aspects described herein relate to indicating, to a base station, to use a separate uplink beam that is different from a downlink beam in transmitting uplink communications, and transmitting uplink communications to the base station based on the separate uplink beam. Additional aspects can relate to performing beam failure detection for the separate uplink and downlink beams.

Abstract: Methods, systems, and devices for wireless communications provide for identification of multiple antenna panels at a user equipment (UE), and determination of panel-specific capabilities for the multiple antenna panels. A UE may determine whether simultaneous communications using two or more antenna panels is supported. The UE may determine that simultaneous communications using two or more antenna panels is supported based on a predetermined rule that indicates such simultaneous communications are supported or unsupported. Whether simultaneous communications on multiple panels is supported may be dependent upon a capability of the UE. The UE may transmit panel-specific capabilities to the base station, that may be used by the base station for subsequent communications between the UE and the base station.

Abstract: Disclosed are techniques for receive beam selection for measuring a reference radio frequency (RF) signal. In an aspect, a first node determines a type of measurement to be performed on the reference RF signal, selects a receive beam based on the type of measurement to be performed on the reference RF signal, generates the selected receive beam, receives, from a second node, using the generated receive beam, the reference RF signal transmitted on a wireless channel, and performs one or more measurements on the received reference RF signal according to the type of the measurement to be performed.

Abstract: Methods, systems, and devices for wireless communications are described that provide for measurement and recovery of beamformed transmission beams in which an uplink beam and a downlink beam may be decoupled beams that use different beamforming parameters. In the event that a user equipment (UE) detects a failure of the downlink beam, an indication may be provided to a base station, and the downlink beam may be switched to correspond to the uplink beam. In the event that the UE detects a failure of the uplink beam the UE may identify a candidate beam and transmit a beam recovery message to the base station. The downlink beam may have an associated first set of reference signals, and the uplink beam may have an associated second set of reference signals, and beam failure may be determined based on the different sets of reference signals.
