Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify conditions associated with one or more physical channels, for example, a set of resources with which the UE may be configured to communicate with a base station. The UE may determine whether to enable a reduced power mode based on the conditions satisfying certain criteria, for example, the set of resources corresponding allocated for particular transmissions. The UE may identify that the conditions satisfy corresponding criteria, and the UE may determine to enable the reduced power mode. The UE may accordingly modify operations one or more components of a receive chain of the UE. The UE may determine to disable the reduced power mode based on the conditions failing to satisfy the criteria, and the UE may modify operations of the one or more components of the receive chain accordingly.

Abstract: Systems and methods to detect spurious responses (spurs) in association with mmWave wireless communications are described. Such spurs may originate internal to the receiver (internal spurs) or external to the receiver (external spurs) originated in the transmitter. Embodiments operate to identify received mmWave wireless communication signal spurs in symbols, or portions thereof, which do not have transmissions directed to the receiving device. mmWave spur detection implementations of embodiments can detect spurs in real-time operation of the receiving device. Such real-time spur detection facilitates operation by the receiving device to perform spur removal in real-time operation of the receiving device, thus enabling removal of both internal spurs and external spurs as well as dynamically adapting to different scenarios that cause different spurs. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a capability of the UE to perform bandwidth-limited envelope tracking or a capability of the UE to compensate for bandwidth-limited envelope tracking distortion. The UE may receive a request for the UE to activate bandwidth-limited envelope tracking or a request for the UE to compensate for bandwidth-limited envelope tracking distortion. In some examples, the UE may transmit an uplink message using a bandwidth-limited envelope tracking configuration. In other examples, the UE may receive a downlink message and use digital post distortion (DPoD) to correct bandwidth-limited envelope tracking distortions in the downlink message. Aspects of the present disclosure may enable the UE to use bandwidth-limited envelope tracking and DPoD for wideband signal transmissions, which may result in lower power consumption at the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request, for an uplink transmission or a downlink transmission, for amplitude modulated phase tracking reference signals; and communicate the uplink transmission or the downlink transmission based at least in part on the request. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment, including in one example: receiving a relay characteristic report, wherein the relay characteristic report indicates an intrinsic channel delay of a relay device; determining a channel delay spread of the channel; and transmitting an indication to affect relay device operation based at least in part on the channel delay spread and the intrinsic channel delay of the relay device.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, when a high subcarrier spacing (SCS) is used for sidelink communications, the user equipments (UEs) may use a modified sidelink slot structure for the sidelink communications. In one example, the slot structure may include at least two automatic gain control (AGC) symbols with at least one sidelink control channel symbol between the two AGC symbols. The UE may perform an AGC procedure during the two AGC symbols and the sidelink control channel symbol. In some examples, the slot structure may include bundled slots to minimize per slot overhead associated with AGC symbols and sidelink control channel symbols. For example, at a high SCS, the slot structure may include a first slot including multiple AGC symbols, Subsequent bundled slots may not include AGC symbols and/or sidelink control channel symbols.

Abstract: Ultra-wide band frequencies used for extended reality (XR) services operate as unlicensed spectrum, which can result in unexpected interference. Although some link adaptation procedures can be used, uncertain link quality can result in sub-optimal utilization of spectrum resources, which may result in poor performance of an XR service. Some aspects described herein enable use of a fixed quantity of re-transmissions of data for an XR frame, with each of the re-transmissions having different XR frame qualities or different quantities of parity bits. The XR device may transmit a feedback message indicating whether the first transmission was successful and may receive a second transmission with additional data for the XR frame. In this way, the XR device can ensure a more efficient use of network resources.
