Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a capability to support a set of frequency bands for wireless communications with an antenna panel. Based on the capability, the UE may receive a first control message from a network entity indicating a portion of the set of frequency bands to use for further wireless communications based on the network entity determining an interference between a set of UEs including the UE and the UE satisfying a threshold interference value. The set of frequency bands may relate to a beamforming scan range. As such, the UE may transmit further wireless communications via a frequency band of the portion of the set of frequency bands based on the first control message and the beamforming scan range.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a user equipment (UE) detects a beam failure of a first beam for a first component carrier (CC) based on a link quality associated with the first beam for the first CC. The first CC and a second CC are within a same group of CCs. The UE initiates one or more beam failure recovery operations associated with any CC within the same group of CCs as the first and second CCs based on a determination of a beam failure of a second beam for the second CC. The determination is based on the detection of the beam failure for the first CC and based on the first CC and the second CC being within the same group of CCs.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may dynamically select subsets of antenna elements within an array based on power consumption and link performance and/or a configuration of components at the wireless device. For example, a wireless device may identify an antenna array having multiple antenna elements, and the wireless device may select respective subsets of antenna elements (e.g., subarrays) for uplink and downlink transmissions. In such cases, the selection may be based on a tradeoff of power consumption at the device and link performance. Additionally or alternatively, the selection may be based on a configuration and/or constraints on a number of radio frequency (RF) components of the wireless device. The wireless device may communicate based on the dynamic selection of different subsets of antenna elements of an array for uplink and downlink communications.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a polarization performance loss indication that is indicative of a loss in polarization performance based on transitioning from a first operating state associated with a first frequency range to a second operating state associated with a second frequency range, wherein the first operating state corresponds to a first antenna configuration and the second operating state corresponds to a second antenna configuration, wherein the first antenna configuration corresponds to a first antenna orientation and the second antenna configuration corresponds to a second antenna orientation. The UE may receive, from the network node, configuration information indicative of at least one communication parameter associated with the at least one antenna array and based on the polarization performance loss indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit, to a network entity, a first signal including a request to update a resolution of a phase shifting operation associated with beam-based communications. The UE may receive, from the network entity, a second signal approving the request. The UE may communicate using a beam according to an updated resolution of the phase shifting operation based on the second signal approving the request. Additionally, or alternatively, the UE may transmit a first signal including a request to suspend a beam refinement process based on the resolution of the phase shifting operation. The UE may receive a second signal approving the request to suspend the beam refinement process. The UE may communicate with the network entity using a beam based on suspending further beam refinement in response to the second signal.

Abstract: Method and apparatus for dynamic polarization combining. The apparatus identifies a first polarization of a first set of antenna elements on a first side of an antenna module having two or more sides. The apparatus identifies a second polarization of a second set of antenna elements on a second side of the antenna module. The apparatus determines, for an antenna layer, a dynamic polarization combination between the first set of antenna elements having the first polarization with the second set of antenna elements having the second polarization. The apparatus communicates with a network node via the antenna module based on the dynamic polarization combination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to report feedback to a base station to address polarization impairments in multiple-input multiple-output (MIMO) communications. The UE and the base station may establish a communications link using a pair of orthogonally polarized beams, where the pair of polarized beams may be selected based on a beam sweep procedure. The UE may transmit a report to the base station indicating one or more polarization parameters associated with beam pairs identified in the beam sweep procedure, such as one or more orthogonality parameters, one or more polarization parameters relating to one or more beam pairs, or one or more angular spread parameters. Based on the report, the base station may transmit a beam configuration to the UE for polarization MIMO communications.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit to a base station a request for resources including an indication of a transmission beam for performing a sidelink communication in a millimeter wave (mmW) system. The base station may determine a transmission configuration based on the request for resources. The UE may transmit reference signals based on the transmission configuration, and the base station may monitor for the reference signals using one or more reception beams. The base station may determine timing information for the sidelink communication, and transmit the timing information to the UE in a resource grant. Based on the timing information, the UE may perform the sidelink communication using the transmission beam. In some examples, the sidelink communication may be multiplexed in frequency from the perspective of the base station with an uplink transmission from another UE.
