Abstract: A UE may determine a number of antenna ports associated with a frequency band that includes one or more CCs. The determined number of antenna ports may be based on a plurality of UL Tx chains for the one or more CCs/frequency band. The UE may switch from a first UL Tx chain to a second UL Tx chain, at least one of which may be associated with the one or more CCs/frequency band. The number of antenna ports may correspond to a maximum number of antenna ports of an individual CC of the one or more CCs, or to a sum of antenna ports of the one or more CCs. For the latter, the number of antenna ports may be limited to an available number of UE antenna ports when the sum of antenna ports is greater than the available number of UE antenna ports.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may support two or more uplink switching periods for transmit chain switching. The UE may transmit a UE capability message indicating the UE capability to support a first uplink switching period and a second uplink switching period for transmit chain switching. The first uplink switching period and the second uplink switching period may each correspond to different switching periods associated with configuration switches between different transmit chain configurations of the UE. The UE and a base station may select an uplink switching period from among the first uplink switching period and the second uplink switching period. The UE may transmit an uplink data message to the base station after a preparation time that is based on the uplink switching period.

Abstract: Certain aspects of the present disclosure provide techniques for provisioning static internet protocol (IP) addresses or prefixes (referred collectively as “addresses” herein) by an application function (AF). For example, the AF may manage (e.g., request to update and/or allocate) static IP addresses for one or more user equipments (UEs), such as for a protocol data unit (PDU) session of a data network name (DNN) of a single-network slice selection assistance information (S-NSSAI).

Abstract: In some aspects, a device may receive a communication indicating a first radar signal pattern parameter set associated with another device. The device may select, based at least in part receiving the communication indicating the first radar signal pattern parameter set, a second radar signal pattern parameter set that is different from the first radar signal pattern parameter set. The device may transmit a radar signal using the second radar signal pattern parameter set. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of one or more switching options supported by the UE, wherein the one or more switching options are associated with performing uplink transmit switching for a first band and a second band. At least one of the first band or the second band is a frequency-division duplex band, a time-division duplex band, or a supplemental uplink band. Uplink multiple-input multiple-output is permitted on the first band and the second band. The UE may receive, after transmitting the indication of the one or more switching options, information associated with an uplink transmission scheduled for the UE, wherein the uplink transmission is scheduled according to the one or more switching options supported by the UE. Numerous other aspects are provided.

Abstract: Various aspects include methods for supporting Enhancement for Television (ENTV) service delivery to a user equipment (UE) in a fifth generation new radio (5G-NR) radio access network (RAN). Various aspects may include generating an ENTV capability message, the ENTV capability message indicating one or more ENTV parameters of the UE, and sending the ENTV capability message to a Next Generation NodeB (gNB) of the 5G-NR RAN. Various aspects may include receiving a ENTV capability message from the UE, the ENTV capability message indicating one or more ENTV parameters of the UE, determining one or more radio resource configurations for the UE based at least in part on the one or more ENTV parameters of the UE, and generating a configuration message indicating the one or more radio resource configurations for the UE, and sending the configuration message to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), such as a vehicle, may access a location-based service using information provided by a roadside unit (RSU). For example, the RSU may generate an indication of a network address associated with the location-based service and may broadcast a sidelink message that includes the indication of the network address to the UE. The UE may receive the sidelink message and may access the location-based service over a connection with a base station using the network address. The UE may access the location-based service based on a location of the UE and may receive location-based information from the location-based service over the connection with the base station.
