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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit a reference signal (RS) for initial beam-pairing (IBP) on an IBP-RS resource specific to transmission of the RS for IBP. The UE may receive, from a second UE, a beam-pairing response associated with the RS for IBP. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include establishing, with a second UE, a sidelink connection. The example method may further include transmitting, to the second UE, sidelink control information (SCI) indicating a demodulation reference signal (DM-RS) pattern from a list of DM-RS patterns including a single symbol DM-RS pattern, the DM-RS pattern being associated with a physical sidelink shared channel (PSSCH) transmission. The example method may further include transmitting, to the second UE based on the PSSCH transmission being associated with a phase tracking signal (PTRS), the PSSCH transmission with a DM-RS based on the single symbol DM-RS pattern and the PTRS associated with the PSSCH transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication associated with a non-uplink transmission state for the UE. The UE may receive scheduling for one or more communications based at least in part on the indication. Numerous other aspects are described.

Abstract: Aspects of this disclosure provide methods, devices and systems for concurrently transmitting control information and data information. In some more specific aspects, a base station may transmit one or more parameters to a user equipment (UE) that indicate to the UE to refrain from transmitting uplink control information together with uplink data information in an uplink data channel. Instead, the one or more parameters may configure the UE to transmit the uplink control information and the uplink data information using overlapping resources in different channels. In some more specific aspects, the UE may transmit the uplink control information in a slot of an uplink control channel and transmit the uplink data information in a slot of the uplink data channel that at least partially overlaps with the slot of the uplink control channel.

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 communications are described. A user equipment (UE) may communicate with a base station in a wireless communications system. The UE may perform a random access procedure to communicate with the base station. The base station may configure the UE with different sets of preamble parameters for different types of UEs. The UE may generate a random access preamble based on the sets of preamble parameters according to the type of the UE. The base station may indicate a location of the base station to the UE. The UE may identify a location of the UE. The UE may determine a pre-compensation timing based on a distance from the two locations. The UE and the base station may transmit subsequent communication according to the random access preamble, the pre-compensation timing, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a configuration associated with cell scheduling. The UE may perform and based at least in part on the configuration and for a cell scheduling of a second cell, a physical downlink control channel (PDCCH) monitoring on a first cell or on the second cell based at least in part on one or more of a discontinuous reception (DRX) state of a first DRX group associated with the first cell or a DRX state of a second DRX group associated with the second cell. Numerous other aspects are described.

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.
