Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an authentication, authorization, and accounting (AAA) server may authorize a use of a third party specific user identity based at least in part on verifying a token associated with a session initiation protocol (SIP) INVITE message with the third party specific user identity. The (AAA) server may transmit, to a call session control function (CSCF) of an originating service provider via a network exposure function (NEF) of the originating service provider, an enterprise name card that indicates the third party specific user identity based at least in part on authorizing the use of the third party specific user identity. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include transmitting, to a second sidelink UE, a first sidelink synchronization block (S-SSB) in a scheduled S-SSB slot, performing a first listen-before-talk (LBT) procedure in an unlicensed frequency band, and transmitting, to the second sidelink UE, a second S-SSB in a slot before a next scheduled S-SSB slot based on the first LBT procedure being unsuccessful.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a first base station associated with a first operator, a broadcast transmission conveying a first portion of a communication; and may receive, without triggering a retransmission of the broadcast transmission, a second portion of the communication via a unicast transmission from a second base station associated with a second operator. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that indicates an uplink transmit switching configuration for performing uplink transmit switching between a first component carrier and a second component carrier and a sounding reference signal (SRS) carrier switching configuration for performing SRS carrier switching between the second component carrier and a third component carrier, wherein the configuration information is associated with a maximum number of allowable switches over an amount of time. The UE may transmit, based at least in part on the configuration information, one or more signals associated with performing at least one of uplink transmit switching or SRS carrier switching. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A person Internet of Things (IoT) network (PIN) architecture may support configuration and management of a PIN. The PIN architecture may include a first network node configured to establish the PIN, a second network node configured as a network gateway for the PIN, a third network node configured as a network management element for the PIN, and a PINE. The first network node may receive, via a user plane of a network, information from the second network node that triggers the first network node to establish the PIN. The first network node may transmit information that identifies and configures the second network node and the third network node as the network gateway and the network management element, respectively. The second network node may relay communications between the PINE and the network.

Abstract: Aspects are provided which resolve neighbor beam-wise interference. A UE obtains a plurality of reference signals from each of at least one neighbor base station, where each of the reference signals is obtained in a different beam, and each of the neighbor base station(s) is in a different neighbor cell. The UE then measures a signal strength associated with each of the reference signals, and the UE indicates one or more of the reference signals to a serving base station in a serving cell, where the signal strength of each of the reference signal(s) indicated to the serving base station exceeds a threshold RSRP. After the serving base station obtains the indication from the UE, the serving base station coordinates with the neighbor base station(s) to modify one or more transmission parameters in response to the indication.
