Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use cover coding for sounding reference signal (SRS) resources for performing antenna switching. The UE may receive a configuration for a reference signal resource set for transmitting a reference signal for antenna switching, the configuration including an indication of a type of time division cover coding for repetitions of the reference signal and an indication of a type of frequency hopping. The UE may determine a reference signal resource for transmission of the reference signal based on the configuration and the type of frequency hopping. The UE may then transmit a set of repetitions of the reference signal over the determined reference signal resource according to the type of time division cover coding.

Abstract: The aspects described herein may enable an apparatus (e.g., a UE) allocated with a portion of a frequency band (e.g., a flexible bandwidth part) to transmit a number of repetitions of an uplink signal transmission when the amount of uplink resources in the portion of the frequency band are insufficient. The apparatus receives a resource allocation that allocates at least one portion of a frequency band to the apparatus, wherein a first slot format is associated with the frequency band and a second slot format is associated with the at least one portion of the frequency band. The apparatus transmits repetitions of an uplink signal transmission in the at least one portion of the frequency band based on the first slot format when the repetitions of the uplink signal transmission cannot be transmitted in the at least one portion of the frequency band based on the second slot format.

Abstract: Aspects are provided which allow a base station to configure flexible BWPs that include a dedicated slot format or may be applied in both DL and UL symbols, and which allow a UE to switch between flexible BWPs in frequency and/or time. The base station configures a first BWP and a second BWP. The first BWP is associated with a first bandwidth and a first slot format dedicated for the first BWP. The base station transmits, to a UE, a configuration to switch the first BWP to the second BWP. The UE receives the configuration from the base station and switches the first BWP to the second BWP. In particular, the UE may switch the first bandwidth to a second bandwidth, the first slot format to a second slot format, or both the first bandwidth and first slot format to the second bandwidth and second slot format, respectively.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) scheduling a downlink transmission. The UE may perform energy harvesting using the downlink transmission. The UE may transmit a hybrid automatic repeat request (HARQ) negative-acknowledgment (HARQ-NACK) based at least in part on using the downlink transmission for the energy harvesting. 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 switch from a first sidelink (SL) full-duplex (FD) mode to a second SL FD mode based on at least one of a first SL discontinuous reception (DRX) pattern associated with the first UE or a second SL DRX pattern associated with the second UE. The UE may communicate in accordance with the second SL FD mode. 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, from a base station, an indication that a downlink (DL) bandwidth part (BWP) and an uplink (UL) BWP are simultaneously active in a time resource. The UE may communicate with the base station via the DL BWP and the UL BWP simultaneously in the time resource in accordance with the indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described to indicate a single frequency network (SFN) mode and associated composite channel reference signals to a user equipment (UE). A UE and a base station may communicate via two or more transmission and reception points (TRPs) using an SFN transmission, which may represent a transmission having multiple beam configurations. The base station may transmit a configuration associated with a control channel that explicitly or implicitly indicates whether control channel transmissions are associated with an SFN mode or are configured with multiple candidate beam configurations. The base station may transmit an indication of activated beam configurations for the control channel. The UE may receive one or more reference signals from each TRP and, based on the SFN indication, may use information from the one or more reference signals to receive the control channel transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from abase station, a sounding reference signal (SRS) configuration indicating a number of candidate slots for transmission of a multi-slot aperiodic SRS (A-SRS); receive, from the base station, an SRS trigger, the SRS trigger comprising an indication of an A-SRS resource set, the A-SRS resource set comprising a plurality of A-SRS resources corresponding to the number of candidate slots; and transmit, in response to the SRS trigger, the multi-slot A-SRS in one or more of a plurality of candidate slots using at least a portion of the A-SRS resource set. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting sounding reference signal (SRS) resources with frequency hopping. In some implementations, a user equipment (UE) may use different SRS ports, different antenna ports, different numbers and sizes of SRS resources, different periodicities, different offsets, different transmission comb values, different number of symbols, different power control parameters, and/or different transmission comb offset values for SRS transmissions on different frequency subbands of the frequency hopping pattern to ensure that sounding operations cover all antennas of the UE, cover the entire frequency range of interest, and provide sufficiently dense SRS transmissions from which a base station can determine the best channel for DL transmissions while also using a minimum amount of SRS resources and consuming minimal power in the UE.
