Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform an initialization procedure with an extended reality (XR) device including a time synchronization and a frequency synchronization. The UE may receive, from the XR device and at a first periodicity, first pilot signals, and may transmit, based on receiving the first pilot signals, a first control message indicating a first set of correction factors to apply to at least one of the time synchronization or the frequency synchronization. The UE may transmit, to the XR device and at a second periodicity, a second pilot signal, and may receive, from the XR device, a second control message including samples of the second pilot signal. The UE may transmit, based on the samples, a third control message indicating a second set of correction factors to apply to the time synchronization between the UE and the XR device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain synchronization with a primary cell (PCell) of a wireless network. The UE may receive an indication to activate a secondary cell (SCell) of the wireless network. The UE may receive a reference signal (RS) of the SCell, reception of the RS of the SCell, based at least in part on obtaining synchronization with the PCell, comprising one or more of: using a reduced candidate beams list for an initial beam search or using a reduced time domain range for receiving the RS of the SCell. The UE may communicate via the SCell based at least in part on synchronization with the SCell and using a beam pair obtained using the RS of the SCell. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may establish a sub-terahertz (sub-THz) link with a sub-THz node, wherein the sub-THz link is associated with a secondary cell (SCell) of the network node, and the sub-THz link is associated with a long-lasting data offloading session. The network node may schedule an additional synchronization and beam management session between the network node and the sub-THz node. The network node may perform synchronization and beam management during the additional synchronization and beam management session to achieve a time synchronization between the network node and the sub-THz node and to refine an SCell transmit (Tx) beam and an SCell receive (Rx) beam for the sub-THz link. Numerous other aspects are described.

Abstract: A UE of a wireless communication network first receives a modulation and coding scheme index IMCS for demodulating a physical layer data channel of the network. The UE then demodulates the physical layer data channel with a non-square quadrature amplitude modulation (NS-QAM) having a modulation order and code rate corresponding to a spectral efficiency (SPEFF) substantially equal to a SPEFF of a square QAM (S-QAM) SPEFF indicted by the IMCS, where the NS-QAM has an effective channel code rate no larger than the code rate for which the UE may skip decoding a transport block in an initial received transmission.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives, from a network entity, signaling dynamically enabling a code block group (CBG) configuration. The UE processes downlink (DL) transport blocks (TBs) including a number of CBGs, in accordance with the CBG configuration. The UE transmits, to the network entity, CBG-level acknowledgment information indicating results of the processing.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to perform receiver-side noise statistics (Rnn) estimation and for an extended reality (XR) device to perform log likelihood ratio (LLR) scaling estimation. For example, the UE may transmit a first set of reference signals to the XR device. The XR device may sample the reference signals and transmit an indication of quantized samples such that the UE may perform Rnn estimations and generate a pre-equalization matrix. The UE may transmit a set of pre-equalized reference signals to the XR device such that the XR device may estimate LLR scaling coefficients. In some examples, the UE may determine the pre-equalization matrix by performing a filtering of reference signal measurements. The UE may apply whitening to account for momentary interference, and may indicate a whitening matrix to the XR device.

Abstract: Aspects of the techniques and apparatuses described herein provide an intra slot antenna diversity scheme that a user equipment (UE) may use to transmit uplink communications while mitigating antenna imbalance. In an intra slot antenna diversity scheme, a UE transmits an uplink communication by transmitting a first portion of the uplink transmission in a first part of a slot using a first subset of antennas and a second portion of the uplink communication in a second part of the slot using a second subset of antennas. A decision to apply an intra slot antenna diversity scheme may be made by a network node such as a base station. Numerous other aspects are described.
