Abstract: Methods, systems, and devices for wireless communications are described to support codebook construction for enhanced hybrid automatic repeat request (HARQ) feedback. A user equipment (UE) may be configured to support a first type of HARQ feedback and a second type of HARQ feedback that includes additional information relative to the first type. A base station may transmit multiple downlink transmissions to the UE, where a first set of the downlink transmissions may be associated with the first type of HARQ feedback and a second set of the downlink transmissions may be associated with the second type of HARQ feedback. The UE may attempt to decode the downlink transmissions and may generate respective feedback for the downlink transmissions. The UE may construct a single HARQ codebook to multiplex the different types of HARQ feedback for the downlink transmissions and may transmit the HARQ codebook to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a first network node (e.g., a user equipment (UE)) receiving first control information indicative of a first feedback scheme for multicast transmissions in a non-terrestrial network (NTN) and determining an applied feedback scheme based on the first feedback scheme. The method may also include the first network node monitoring for a multicast transmission and operating in accordance with the applied feedback scheme.

Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to signal a capability corresponding to a number of active beams (e.g., active uplink beams) to a base station so that the UE may be appropriately configured, and so that the UE may communicate with the base station accordingly. Furthermore, some techniques and apparatuses described herein permit a UE and/or a base station to apply one or more rules and/or conditions to assist with ensuring that a UE capability, corresponding to a number of active beams (e.g., active uplink beams), is not violated, or to prevent the UE from communicating on a beam that is invalid due to a violated UE capability. Furthermore, some techniques and apparatuses described herein permit a UE and a base station to perform a beam management procedure upon beam activation to ensure that a beam is of sufficient quality for communications.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may receive signaling from a network entity configuring a sounding reference signal resource set comprising a first sounding reference signal resource associated with a first subset of a total number of sounding reference signal ports and a second sounding reference signal resource associated with a second subset of the total number of sounding reference signal ports supported by the UE. The UE may transmit sounding reference signals via at least one sounding reference signal resource of the plurality of sounding reference signal resources based on the signaling configuring a sounding reference signal resource set. The UE may receive a downlink control information message comprising an indication of a physical uplink shared channel transmission based on at least a subset of the total number of sounding reference signal ports. The UE may transmit the physical uplink shared channel transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, via a sidelink interface, a message from a second UE. The UE may transmit, to the second UE, sidelink resource information for sidelink resources that are available to the second UE, wherein the sidelink resource information is based at least in part on a measured power level associated with the message received from the second UE. Numerous other aspects are provided.

Abstract: In some aspects, a method of wireless communication includes receiving, at a user equipment (UE) from a base station, a first message indicating a selected carrier for transmission of an uplink (UL) message. The selected carrier includes a UL carrier or a supplementary uplink (SUL) carrier. The UL carrier and the SUL carrier correspond to the same cell. The method further includes transmitting the UL message to the base station via the selected carrier. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a network entity may support a configured grant (CG)-specific retransmission timer configuration based on a traffic type to be communicated using a given CG. For example, the network entity may indicate a CG for uplink transmissions and may indicate a retransmission timer that is specific to the CG. As such, the UE may transmit a data message in accordance with the CG and may select a time period during which to monitor a downlink control channel for control information indicating a retransmission request for the data message in accordance with a value of the retransmission timer. Additionally, or alternatively, the UE and the network entity may support a downlink-to-uplink configuration dependency for determining an uplink periodicity of a CG based on a downlink periodicity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity configuring a virtual cell group with multiple cells, where each cell may have a radio frequency spectrum band with a frequency gap that exceeds an operating band threshold. The network entity may transmit additional control signaling including information for the virtual cell group. In some cases, the additional control signaling may include resource allocation information for the virtual cell group, such that the UE may communicate multiple shared channels via different cells in the virtual cell group using the resources indicated in the resource allocation information. In some other cases, the additional control signaling may include a cancellation indication for the virtual cell group, such that the UE may refrain from communicating signals using one or more cells of the virtual cell group.
