Abstract: Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes. ACK/NAK bits may also be allocated to all special subframes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may drop a first one or more device-to-device coordination messages for transmission, of a set of device-to-device coordination messages, according to a message dropping criterion in connection with a quantity of device-to-device coordination messages in the set of device-to-device coordination messages exceeding a threshold. The UE may transmit a second one or more device-to-device coordination messages of the set of device-to-device coordination messages, such that a quantity of transmitted device-to-device coordination messages, of the set of device-to-device coordination messages, does not exceed the threshold. Numerous other aspects are described.

Abstract: In one aspect, a method of wireless communication includes determining, by a user equipment (UE), one or more full-duplex symbols of a slot and one or more half-duplex symbols of the slot; determining, by the UE, to use a first type of interleaving for the one or more full-duplex symbols and a second type of interleaving for the one or more half-duplex symbols; frequency domain mapping, by the UE, virtual resources of the slot to physical resources of the slot based on the first type of interleaving and the second type of interleaving; and communicating, by the UE, based on the physical resources. Other aspects and features are also claimed and described.

Abstract: Techniques are described herein for determining a priority ranking for channel state information (CSI) reports based at least in part on a reliability parameter, a latency parameter, or both of resources allocated to a user equipment (UE). In some wireless communications systems, ultra reliable low latency communication (URLLC) services may be interspersed with enhanced mobile broadband (eMBB) services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters or both. In some cases, CSI reporting for resources associated URLLC services may receive higher priority than CSI reporting for eMBB services. The UE may be configured to determine reliability parameters and/or latency parameters based on signaling received from the network or from determining changes to one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based at least in part on a slot set identifier.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more communication patterns from a base station. The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross-link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.

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.
