Abstract: Methods, systems, and devices for wireless communications are described in which a block error rate (BLER) in non-terrestrial network (NTN) communications may be reduced through coverage enhancement techniques. Coverage enhancement techniques may include slot bundling for physical downlink control channel (PDCCH) communications, in which repetitions of a PDCCH may occupy multiple time-frequency locations spanning multiple slots. Such slots can be consecutive or non-consecutive, and in some cases multiple repetitions of the PDCCH may be provided within the same slot. The pattern of the time-frequency locations of repetitions may be periodic or non-periodic. Further, the repetitions can be exact copies, or different redundancy versions of the same encoded DCI. Additionally, repetitions of uplink or downlink shared channel communications, uplink or downlink control channel communication, broadcast channel communications, or any combinations thereof, may be provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a first uplink transmission using a first transmit power that is based at least in part on: a first power level associated with the first uplink transmission, and a power scaling factor based at least in part on a power offset. The UE may transmit, to the network node, a second uplink transmission, at least partially overlapping in time with the first uplink transmission, using a second transmit power that is based at least in part on: a second power level associated with the second uplink transmission, a maximum available transmit power, and the first transmit power. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive an indication of a configuration for transmitting a sidelink reference signal (SL-RS) that is to be transmitted independently of data transmission and that has a frequency bandwidth that is independent of a frequency bandwidth configured for transmission on a physical sidelink shared channel. The UE may transmit the SL-RS to a second UE according to the configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate over multiple component carriers (CCs). The UE may receive control signaling indicating a joint feedback codebook configuration for jointly reporting feedback for a first CC, a second CC, and a virtual CC that may be mapped to a third CC and a fourth CC. The UE may then receive downlink control information (DCI) scheduling a first downlink transmission via the first CC and a second downlink transmission on the second CC, or both downlink transmissions may be scheduled via the virtual CC. The UE may transmit a joint feedback message for the first CC, the second CC, and the virtual CC based on the joint codebook configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an AMF may receive, from a user equipment (UE), a communication associated with a request for an identifier. The AMF may transmit, to the UE, the identifier, wherein the identifier is based at least in part on a synchronization signal block (SSB) periodicity and a number of paging frames per discontinuous reception (DRX) cycle. Numerous other aspects are described.

Abstract: Wireless communication devices, systems, and methods related to handling wake-up behavior for power saving, including during discontinuous reception (DRX) operation are provided. For example, a method of wireless communication includes transmitting, by a base station (BS) to a user equipment (UE), a default wake-up configuration associated with a discontinuous reception (DRX) operation; determining, by the BS, whether to transmit a wake-up signal (WUS) to the UE during a WUS occasion based on a traffic load; and transmitting, by the BS, a physical downlink control channel (PDCCH) signal during a duration associated with the WUS occasion.

Abstract: A user equipment (UE) having a first capability associated with a lower maximum UE bandwidth than a second capability performs at least a part of initial access based on an initial downlink bandwidth part (BWP) that is shared among UEs having the first capability and UEs having the second capability. The UE switches, after the initial access, to an active downlink BWP and an active uplink BWP that are dedicated for the UEs having the first capability to perform random access, paging, system acquisition, measurement and data communication procedures.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first message to indicate a sidelink bandwidth part (BWP) switch, for the first UE, to a first sidelink BWP, wherein the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The UE may receive, from the second UE, a second message that confirms the sidelink BWP switch for the first UE. The UE may transmit, to the second UE, a third message to activate the sidelink BWP switch, for the first UE, to the first sidelink BWP, based at least in part on receiving the second message that confirms the sidelink BWP switch. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a coordinate switch indication that indicates that the UE is to calculate a first value of a new ephemeris coordinate of a plurality of coordinates. The UE may calculate the first value of the new ephemeris coordinate based on one or more other ephemeris coordinates of the plurality of ephemeris coordinates and may generate ephemeris information, associated with a non-terrestrial communication device, based on the calculation of the first value of the new ephemeris coordinate. The UE may communicate with the non-terrestrial communication device based on the ephemeris information. Numerous other aspects are described.
