Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive control signaling configuring periodic resources for receiving semi-persistent scheduled downlink transmissions and may receive a control message indicating a change to a transmission time interval format. The UE may identify a conflict for a symbol period between uplink transmission of feedback for a first semi-persistent scheduled downlink transmission and downlink reception based on the change to the transmission time interval format. The UE may then transmit, in an uplink shared channel resource of the transmission time interval format that differs from the symbol period, an uplink message including uplink data multiplexed with the feedback based on the conflict.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may apply a crest factor reduction (CFR) to an input signal to generate an output signal, the applying the CFR to the input signal including applying a shaping filter that distributes a first portion of CFR noise within a transmission frequency band of the output signal and a second portion of the CFR noise in at least one air interface resource that is outside of the transmission frequency band of the output signal. The network node may transmit the output signal. 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 network entity, a physical downlink shared channel (PDSCH) transmission in a first slot, wherein the PDSCH transmission is associated with a codebook timespan. The UE may perform, to the network entity, a physical uplink control channel (PUCCH) transmission in a subsequent slot based at least in part on an adjustment to the codebook timespan, wherein the PUCCH transmission indicates a hybrid automatic repeat request (HARQ) associated with the PDSCH transmission. 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, via a first cell, an indication to activate a second cell. The UE may receive, via the second cell, a synchronization signal block (SSB) associated with a first type of time synchronization of the UE on the second cell, the SSB including a primary synchronization signal and the SSB omitting a physical broadcast channel (PBCH), demodulation reference signals (DMRSs), and/or a master information block. The UE may receive, via the second cell and based at least in part on the first type of time synchronization, a reference signal associated with one or more of: a second type of time synchronization on the second cell, a frequency synchronization on the second cell, or an automatic gain control (AGC) synchronization on the second cell. Numerous other aspects are described.

Abstract: Aspects of the present disclosure allow a UE to request, in an anchor carrier on one frequency band, a base station to configure and transmit A-TRS in an SSB-less secondary carrier on a different frequency band. The UE transmits, in a first cell served by the anchor carrier, a request for A-TRS. Based on the request, the UE receives, in a second cell lacking SSB transmissions served by the secondary carrier, the A-TRS based on the request. The base station may also control transmission of the A-TRS in the SSB-less secondary cell based on a timer derived from the request. Using the A-TRS, the UE may apply AGC and time/frequency tracking loop operations prior to receiving a PDSCH in the SSB-less secondary cell, thereby improving reception performance of downlink data transmissions in the secondary carrier. Thus, network energy savings provided by SSB-less secondary carriers may be obtained in inter-band CA.

Abstract: Methods, systems, and devices for wireless communications are described herein. To support network energy savings, a user equipment (UE) may receive, from a network entity, control signaling that indicates a configuration for measuring uplink packet delay for transmission of a packet. The UE may generate a measurement of the uplink packet delay for transmission of the packet. The measurement may correspond to a duration between a packet arrival time at a packet data convergence protocol layer of the UE and a transmission or a retransmission of the packet. The UE may transmit control signaling that indicates the generated measurement. The network entity may obtain the measurement and evaluate whether to switch a cell to an off state based on the obtained measurement.
