Abstract: Aspects relate to using less than all of an allocation for sending information. For example, a first device such as a user equipment (UE) may receive a grant from a second device such as a base station (e.g., a gNB) where the grant identifies resources and/or a modulation and coding scheme (MCS) allocated to the first device for a transmission. Due to one or more factors, the first device may elect to not use all of the allocated resources and/or may elect to use a lower MCS value. In some implementations, the first device may send an indication of this election to the second device. In some implementations, the first device may send information in a first subset of the allocated resources and apply puncturing to a second subset of the allocated resource.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications networks, a device, such as a user equipment (UE), may be configured to detect a signal blockage affecting one or more antennas of the UE. The signal blockage may be associated with the position of a body, such as a user, relative to the one or more antennas of the UE, which may include how a user places their hand on or near the device during use. The position of the body may block one or more of the antennas of the UE, causing increased signal attenuation and decreased communications performance. The UE may be configured to signal, an indication based on detecting the signal blockage.

Abstract: In an aspect, a user equipment (UE) may receive an uplink (UL) grant (e.g., dynamic UL grant, UL configured grant (CG)) from a network, but may decide to skip the UL grant altogether or not transmit any user plane data on the UL grant. In such instances, the UE may maintain or expedite expiration associated with one or more timers (e.g., discontinuous reception (DRX) and bandwidth part (BWP) inactivity timers, secondary cell (SCell) deactivation timer, etc.). The UE may also maintain or expedite expiration associated with one or more timers if it receives downlink (DL) transmission (e.g., DL semi-persistent scheduling (SPS)) from the network that includes no user plane data.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for managing scheduling requests (SRs) in a user equipment (UE) that supports a split data radio bearer (DRB). In some aspects, the UE may trigger a first SR for a first communication link and a second SR for a second communication link in response to determining that a first amount of data in the UE data buffer is greater than a first threshold. The UE may transmit the first SR to a first base station (BS) via the first communication link. Prior to transmission of the second SR, the UE may determine whether a second amount of data in the UE data buffer is less than a second threshold. The UE may cancel the second SR in response to the second amount of data in the UE data buffer being less than the second threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a first carrier associated with a first radio access technology, at least a first uplink grant from a base station. The UE may implement one or more backoff schemes. For example, the UE may transmit, using resources indicated by at least the first uplink grant, an uplink message based on a temperature of one or more components of the UE satisfying a threshold, the uplink message including a transport block (TB) indicating data, a buffer status report (BSR) associated with the data, one or more padding bytes different from the data, or any combination thereof. The UE may monitor for at least a second uplink grant from the base station during a first time period based on transmitting the uplink message.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving a number of uplink grants from a base station. The method further includes estimating a payload size for data to be transmitted from a UE buffer for a number of logical channels. The payload size corresponds to a sum of a number of data bytes to be transmitted and an amount of overhead bytes to be transmitted. The method still further includes determining a subset of the number of uplink grants to use for uplink transmission based on reducing a total padding size associated with transmitting the payload size, for each combination of the number of uplink grants. The method also includes transmitting the data from the UE buffer within a number of transport blocks, to the base station. The number of transport blocks corresponds to the subset of the number of uplink grants.
