Abstract: Techniques and apparatus for transmitting control information to maintain hybrid automatic repeat request (HARQ) processes for multiple carriers in different frequency ranges, such as frequency range 1 (FR1) and frequency range 2 (FR2), in carrier aggregation scenarios are described. A first numerology of a first component carrier (CC) in FR1 and a second numerology of a second CC in FR2 are determined. A HARQ configuration that includes an indication of a set of physical uplink control channel (PUCCH) resources is determined. A number of symbols of the set of PUCCH resources is based on the first numerology and the second numerology. The HARQ configuration is transmitted to a user equipment (UE). HARQ feedback is transmitted on the first CC for data received on the second CC, using the set of PUCCH resources of the HARQ configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to transmit a compact uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU). The UE may transmit the UCI in the PRU based at least in part on a semi-static payload construction and resource mapping rule. Numerous other aspects are provided.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from transmissions from an aggressor UE. The present disclosure provides for a cell-group transmission power control (TPC) command that allows the base station to adjust the transmission power of uplink transmissions on multiple cells in order to mitigate cross-link interference. A UE may receive the cell-group TPC command as a single downlink control information (DCI) that indicates a plurality of TPC commands for a plurality of cells that are configured for the UE. The UE may adjust a transmit power for a respective uplink transmission for each respective cell of the plurality of cells based on a respective TPC command of the plurality of TPC commands.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), operating in a serving cell, may adjust a transmit power of an uplink message when a neighboring cell is operating in an opposite direction (e.g., relative to the direction of communications in the serving cell) within a same or similar frequency band in a same time period. The UE may receive control signaling that indicates a first power control configuration to be used when the neighboring cell is operating in a same direction as the serving cell and a second power control configuration to be used when the neighboring cell is operating in a different direction from the serving cell. The UE may select the appropriate power control configuration based on the communications directions of the serving cell and the neighboring cell and may transmit the uplink message in accordance with the selected power control configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a mapping between synchronization signal blocks (SSBs) and a random access message of a two-step random access procedure based on an indication in system information signaling or radio resource control (RRC) signaling. The random access message may include a random access preamble and a random access payload. The UE may determine, based on the mapping, an association between one or more beams carrying the SSBs and one or more additional beams carrying the random access preamble and the random access payload of the random access message. As a result, the UE may perform the two-step random access procedure with a base station according to the beam association, and coexist with a four-step random access procedure in a more reliable and efficient manner.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a UE or base station may identify a first portion of a payload associated with a first priority and a second portion of the payload associated with a second priority less than the first priority. The UE or base station may select a first matrix associated with a first domain for the first portion of the payload and a second matrix associated with a second domain for the second portion of the payload based on a first maximum index interval for the first matrix being larger than a second maximum index interval for the second matrix. The UE may transmit or the base station may receive the first portion of the payload using one or more sequences associated with the first matrix and the second portion of the payload using one or more sequences associated with the second matrix.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a data message to a user equipment (UE) in a data block modulated according to a modulation and coding scheme (MCS). The UE may monitor for the data block and may attempt to decode the data block. If the UE successfully receives and decodes the data block, the UE may transmit an acknowledgment (ACK) in a feedback message. If the UE unsuccessfully receives or decodes the data block, the UE may transmit a negative acknowledgement (NACK). The UE may transmit the feedback message with the ACK or NACK and a value from a codebook indicating for the base station to increase or decrease the MCS by a delta value for a following transmission or a retransmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first base station may communicate during asynchronous slots in accordance with a set of communication parameters determined from a handshake procedure performed with a second base station. For example, based on a change to a slot type of a slot to an asynchronous slot, the first base station and the second base station may perform the handshake procedure to determine the set of communication parameters and may communicate one or more messages during the slot in accordance with the set of communication parameters. Additionally, or alternatively, a user equipment (UE) may transmit a sounding reference signal (SRS) associated with a transmission configuration indicator (TCI) state based on a slot type of a first slot in which the UE transmits the SRS and a reference signal received in a second slot having the slot type.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, an indication of whether the UE is capable of using a virtual port to transmit uplink communications using a maximum transmit power according to a power class of the UE, wherein the virtual port is a combination of two or more antenna ports. The UE may receive, from the base station, a sounding reference signal configuration based at least in part on the indication. Numerous other aspects are provided.
