Abstract: In some aspects, a user equipment (UE) determines a transmission gap adjustment (TGA) for a first message (msgA) of a 2 step random access channel (RACH) procedure based on measurement of a reference signal transmitted by a base station as well as the radio resource configuration (RRC) configurations for msgA. In other aspects, a base station transmits a system information block (SIB) or RRC signaling that indicates at least one possible configuration of the TGA, and UEs determine the TGA depending on RRC state. Connected mode UEs having a timing alignment (TA) timer running may determine the TGA based on a previous TA. UEs in other RRC modes determine the TGA based on the possible configuration transmitted in the SIB or RRC signaling. Advantageously, 2 step RACH UEs are able to communicate with the base station without the closed loop TA information provided by a 4 step RACH.

Abstract: Certain aspects of the present disclosure provide techniques for identifying, from a resource pool allocated for sidelink communications between UEs, a first number of resources for transmissions from the first UE to a second UE based on a set of one or more parameters shared between the first UE and the second UE and identifying, from the resource pool, a second number of resources for transmissions from the second UE to the first UE based on the shared set of one or more parameters. The first UE may communicate with the second UE using the first and the second number of resources and avoid using the remaining available resources for power saving. For example, the first UE and the second UE may avoid sidelink communications on time slots on which no subchannels belong to either the first subset or second number of the resources.

Abstract: This disclosure provides methods, devices, and systems for physical uplink shared channel (PUSCH) repetition based on support signaling, such as an uplink grant that includes a time domain resource assignment for transmitting one or more data repetitions that may cross a slot boundary. The UE may identify directions (for example, uplink, downlink, flexible) for one or more symbols spanning a transmission duration of the time domain resource assignment. The directions may be determined using a dynamic slot format indication (SFI), or semi-static SFIs may be used as a fallback (when dynamic slot format indications do not meet a target reliability). The uplink grant may include an indication of which symbol directions can be used for the one or more data repetitions. A subset of the one or more symbols for scheduling the one or more data repetitions may be determined based on the identified directions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving cell, first signaling that includes one or more time division duplexing (TDD) patterns associated with a neighboring cell. The UE may receive second signaling that includes a slot format indicator (SFI) associated with the neighboring cell. The UE may determine a slot configuration allocating transmission time intervals (TTIs) in the neighboring cell to one or more of downlink communication or uplink communication based at least in part on the one or more TDD patterns associated with the neighboring cell and the SFI associated with the neighboring cell. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure relate to uplink preemption in certain systems, such as new radio (NR) systems, supporting carrier aggregation (CA) and/or multi-connectivity modes. A method for wireless communication, that can be performed by a user equipment (UE), generally includes receiving a resource assignment scheduling the UE for uplink transmission. The UE receives an indication to preempt uplink transmission on a portion of the assigned resources and determines whether to transmit on the remaining assigned resources. A method that can be performed by a base station (BS) generally includes receiving an indication from one or more UEs indicating, for each of a plurality of band combinations, a capability of the UE to transmit on a band when transmission on another band in the band combination is preempted and scheduling the one or more UEs for uplink transmission based on the indication.

Abstract: Methods, systems, and devices for wireless communications are described that support demodulation reference signal (DMRS) multiplexing scheme selection for uplink transmission. A user equipment (UE) may monitor for a parameter from a base station indicating which DMRS scheme to use. In some cases, the base station may transmit a radio resource control (RRC) parameter indicating a first DMRS scheme to the UE. The UE may select the first DMRS scheme based on receiving the RRC parameter from the base station or based on a default DMRS scheme. The UE may transmit a transmission based on the first DMRS scheme.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.

Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may receive downlink control information, and may determine assignment information for processing batch-based feedback based on the downlink control information. The UE may determine the batch-based feedback for a batch of downlink transmissions (for example, transmissions associated with packets of information) that are configured to be processed together by the UE. The UE may receive a downlink transmission from the base station, and may construct a codebook based on assignment information and the downlink transmission. In some examples, the UE may determine acknowledgment feedback for the downlink transmission based on the codebook. The UE may transmit the acknowledgment feedback to the base station.
