Abstract: Aspects are presented that enable a user equipment (UE) to perform simultaneous transmission of supplementary uplink carriers. The UE can transmit, to a base station, a capability message of the UE, the capability message indicating whether the UE supports simultaneous transmission of uplink signaling on supplementary uplink carriers. The UE can receive, from the base station, schedule information scheduling simultaneous transmission of a first uplink transmission on a first carrier in a first cell and a second uplink transmission on a second carrier in a second cell different from the first cell based on the capability message. The UE can transmit, to the base station, the first uplink transmission on the first carrier via the first cell simultaneous with the second uplink transmission on the second carrier via the second cell.

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: 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: 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: Aspects for enabling Multiple-Input-Multiple-Output (MIMO) communications using a plurality of transmitters across at least two supported frequency bands are disclosed. The apparatus may be a user equipment (UE) that includes, for each UE-supported frequency band, a plurality of transmitters capable when configured of coherently transmitting the received information over the frequency band with information to be transmitted to a base station. The apparatus can identify MIMO coherence capability information for the supported frequency bands on a per-band and a per-band combination basis. The apparatus may determine a proposed transmission configuration based on the MIMO capability information and may report, to the base station, the proposed transmission configuration.

Abstract: To facilitate operations of a low-power UE with high RF sensitivity, methods, apparatuses, and computer-readable medium are provided. An example method includes receiving, from a base station or a second UE, a reservation reserving a set of time-domain resources and a set of frequency domain resources around a WUS for a low-power UE. The example method further includes refraining from transmitting in the reserved resources.

Abstract: A user equipment may be configured to limiting transmit power for frequency domain division for high power user equipment. In some aspects, the user equipment may determine a UE context is interference limited or noise limited based on comparing a measurement value to a threshold value, set a maximum transmit power based on the UE context, and transmit, during a time period associated with a downlink (DL) grant, an uplink (UL) transmission at the maximum transmit power.

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.
