Abstract: Methods, systems, and devices for wireless communications are described. A base station may indicate to a UE a first set of uplink power control parameters associated with half-duplex communications and a second set of uplink power control parameters associated with full-duplex communications. Alternatively, the base station may indicate the first set of uplink power control parameters and a set of power offsets associated with full-duplex communications. The base station may indicate a first set of resources associated with the first set of uplink power control parameters and a second set of resources associated with the second set of uplink power control parameters or the set of power offsets. In response, the UE may transmit one or more uplink messages over one or more resources of the second set of resources in accordance with the second set of uplink power control parameters or the set of power offsets.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message that indicates an antenna module configuration, the antenna module configuration indicating an antenna module format of the UE. The UE may perform a beam management procedure according to a beam management mode associated with a frequency range and corresponding to the antenna module format and may receive, based on the beam management procedure, an indication of a set of parameters for communications using the frequency range. The UE may communicate, based on the set of parameters, one or more messages using the frequency range and one or more antenna modules. Additionally, or alternatively, the UE may receive an indication of a resource allocation for a beam weighting procedure, the resource allocation corresponding to the antenna module format of the UE and may perform the beam weighting procedure using the resource allocation.

Abstract: Certain aspects of the present disclosure provide techniques for selecting and indicating a quasi colocation (QCL) source signal for sidelink (SL) communications. For example, a scheduling node may select from multiple candidates a signal for a first user equipment (UE) to use as a spatial QCL source for a receive (RX) or transmit (TX) beam to use for communicating with a second UE on a SL interface. The scheduling node may then signal the first UE an indication of the selection of the signal.

Abstract: Methods, systems, and devices for sidelink groupcast communications are described. A user equipment (UE) may transmit a beam training request to a base station to determine beams for use with other UEs in a sidelink groupcast communications group. The base station may receive the beam training request, identify wireless resources that a group of UEs may use to perform beam training, and may transmit a beam training grant to each UE of the group of UEs. The UE may transmit a number of training beams using the wireless resources provided in the beam training grant, and the other UEs may measure received signals on the wireless resources to identify one or more beams. Each UE may provide a beam training report to the base station. The base station, based on the beam training reports, may determine beams and resources for use in the groupcast sidelink communications.

Abstract: Aspects of the disclosure relate to millimeter wave (mmWave) device discovery for relay communication using pseudo-omnidirectional beams. A first user equipment (UE) may transmit a synchronization signal over each pseudo-omnidirectional beam to enable a second UE to discover a presence of the second UE within a range of the first UE. Upon the occurrence of an external event, a base station may either trigger a beam training procedure with the second UE to establish a relay link between the first and second UEs or broadcast a message to all UEs requesting a relay link be established with the first UE. The first and second UEs may then select a directional beam pair link (BPL) for the relay link and establish the relay link to enable information to be relayed between the base station and the first UE via the relay link.

Abstract: Aspects relate to mechanisms for wireless communication devices to update transmission configuration indicator states (TCI-states), spatial relation (SR) indicators (SRIs), or pathloss reference signals (PL-RSs) for a group of two or more component carriers (CCs) for multi-component carrier communication. A radio access network (RAN) node may generate a message indicating one or more TCI-states, one or more SRs, or one or more PL-RSs to utilize for multi-CC communication. The message may include an index identifying a group of two or more CCs of a plurality of access CCs or a plurality of sidelink CCs associated with the one or more TCI-states, the one or more SRs, or the one or more PL-RSs. A user equipment (UE) may receive the message and update the one or more TCI-states, the one or more SRs, or the one or more PL-RSs for the group of two or more CC for the multi-CC communication based on the message.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for signaling user equipment (UE) capability for sharing quasi co-location (QCL) parameter across a group of frequency bands. For example, the UE may report, to a network entity, a capability of the UE to apply a common spatial QCL parameter for at least one group of frequency bands. The UE receives an indication of a change to the common transmission control indicator (TCI) states or spatial relation parameter to be applied across the group of frequency bands. The UE applies the change across the group of frequency bands.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving user equipment (UE) may broadcast messages containing inter-UE cooperation (IUC) information using multiple beams. The IUC information transmitted on each beam may be different for each beam of the receiving UE. For example, each IUC information may contain different preferred resources or non-preferred resources for the receiving UE to receive a transmission from a transmitting UE. The transmitting UE may receive a message containing IUC information from one of the beams of the receiving UE and transmit a signal using resources based on the IUC information contained in the received message. In some examples, the transmitting UE may transmit a channel busy ratio (CBR) request to a receiving UE. The CBR request may specify a transmission configuration indicator (TCI) state, spatial relation, spatial domain filter, or beam according to which the receiving UE is to measure the CBR.

Abstract: Methods, systems, and devices for identification reinterpretation in sidelink control information (SCI) are described. A first user equipment (UE) may transmit to a second UE or device, on a sidelink channel, SCI. The SCI may include a partial source and destination identifier fields and may indicate to the second UE to apply a first interpretation of multiple different interpretations for the partial source identifier field and the partial destination identifier field. For example, the SCI may indicate to interpret the partial source identifier field and the partial destination identifier field in combination as a source identifier field, as a destination identifier field, or as a partial source identifier and a partial destination identifier. The UE may transmit a medium access control (MAC) packet including a MAC header with identifier fields set to be complementary to the SCI.
