Abstract: According to example embodiments, a method for wireless communications by a user equipment (UE) is included. The method generally includes performing channel estimation at a plurality of frequency locations based on reference signals (RS) transmitted from at least one transmission point, computing at least one channel feedback metric for each frequency location, and transmitting the channel feedback metrics to the transmission point.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment may receive an indication of a pre-paging signal configuration for reception of a pre-paging signal associated with a first cell. The UE may monitor for the pre-paging signal from the first cell in response to one or more conditions being satisfied, the one or more conditions based at least in part on the pre-paging signal configuration. In some examples, the UE may receive, based on the monitoring, the pre-paging signal from the first cell, and the UE may output an alert message associated with receiving the pre-paging signal, the alert message indicating for the UE to be relocated to improve coverage.

Abstract: Some techniques described herein provide autonomous modification of a modulation and coding scheme (MCS) of a grant for a transmission by a user equipment UE. For example, the UE may receive a grant (e.g., a configured grant) indicating a resource allocation and a first MCS for a transmission on the resource allocation. The UE may use the resource allocation for a transmission of a number of transport blocks (e.g., one or more transport blocks), and may use a second MCS, different than the first MCS, for the transmission. In some examples, the second MCS may be a lower MCS, associated with a lower modulation scheme and/or code rate, than the first MCS. Thus, a per-resource-block power consumption of the transmission is decreased by using the second MCS, which provides power savings while reducing or eliminating padding of the uplink communication.

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 configuration that indicates a time alignment timer associated with a timing advance group (TAG) for a bandwidth part (BWP) or a component carrier (CC) configured for multiple downlink control information (multi-DCI) based multiple transmission reception point (multi-TRP) communications. The UE may start the time alignment timer for a TRP. The UE may flush one or more hybrid automatic repeat request (HARQ) identifiers (IDs) from a HARQ buffer associated with the TRP based at least in part on an expiration of the time alignment timer. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described in which multiple devices may implement sidelink communications for direct device-to-device exchange of information. Such devices (e.g., user equipment (UE) devices) may be configured with resources for sidelink communications, and may monitor for a sidelink preemption indication (SPI) from a base station and determine whether one or more sidelink communications is preempted based on the SPI. The sidelink communications may include a feedback communication that is transmitted using sidelink feedback resources. Based on an indication in a received SPI, it may be determined whether or not to transmit sidelink feedback. The sidelink feedback may be transmitted to one or more other sidelink devices, or to a base station, and preemption of the sidelink feedback may be determined based on one or more parameters associated with the sidelink communications, associated with the SPI, or any combinations thereof.
