Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate an uplink control information (UCI) message including a first UCI bit multiplexed with a second UCI bit, the first UCI bit having a first sequence applied and the second UCI bit having a second sequence, that is orthogonal to the first sequence, applied. The UE may transmit the UCI message. Numerous other aspects are described.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a codebook type for transmitting hybrid automatic repeat request (HARQ) feedback by the UE to a second device (e.g., a network device, a satellite, or a base station). The indication of the codebook type may indicate a HARQ feedback transmission configuration, such as a static HARQ feedback transmission configuration. The HARQ transmission configuration may be associated with a one bit or two bit HARQ codebook. The UE may receive a scheduled downlink shared channel transmission, and attempt to decode the received downlink shared channel transmission. The UE may transmit (or refrain from transmitting) the HARQ feedback based on the decoding of the scheduled downlink shared channel transmission and in accordance with the feedback mode.

Abstract: Methods and devices for discontinuous reception signaling for wireless communications systems are described. A base station may determine a semi-persistent scheduling (SPS) configuration and a discontinuous reception configuration (DRX) associated with the semi-persistent scheduling (SPS) configuration for a user equipment (UE). The base station may transmit the SPS configuration to the UE. The SPS configuration may indicate one or more DRX parameters for the DRX configuration. A UE may receive the semi-persistent scheduling configuration from the base station. The UE may identify one or more DRX parameters for the discontinuous reception configuration based on the SPS configuration. The UE may monitor a downlink control channel in accordance with the DRX configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information indicating a reservation or allocation of a resource for transmission of a first signal by another network node, wherein the information identifies whether the network node is to use the resource for transmission of a second signal concurrently with the first signal. The network node may transmit the second signal in the resource based at least in part on the information identifying whether the network node is to use the resource for transmission of the second signal. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to a downlink search space with or without PDCCH monitoring aggregation in a wireless communication network are provided. A UE receives a monitoring configuration from a BS including a repetition of DCI over a plurality of PDCCH monitoring occasions of a search space. The monitoring configuration indicates one or more forms of diversity between PDCCH monitoring occasions. Diversity may be achieved, for example, by a CORESET frequency allocation difference, a PDCCH monitoring occasion frequency resource allocation difference, and/or different hashing functions for the CCE index of PDCCH monitoring occasions within a CORESET. Additional diversity is possible by using different beams and other methods. When activated either explicitly or implicitly, UE monitors for PDCCH transmissions from the first device utilizing the configured PDCCH monitoring aggregation.

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. The virtual port may be a combination of one or more antenna ports. The indication may be based at least in part on an operating mode of the UE. 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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, via first frequency ranges and first time periods, a plurality of sidelink control blocks that each indicate a sidelink positioning reference signal burst pattern for one or more sidelink UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity, such as a base station, may receive, from a first network entity, a broadcast indicating a downlink control channel transmission pattern associated with the first network entity. The network entity may monitor a plurality of receive beams for a plurality of downlink control channel transmissions from the first network entity according to the downlink control channel transmission pattern and may select a communication beam according to one or more cross-link interference (CLI) measurements associated with one or more of the plurality of receive beams in accordance with the monitoring. The network entity may communicate with a user equipment using the selected communication beam and a first set of resources that at least partially overlap in time and frequency with a scheduled communication at the first network entity. The network entity may experience or may cause the measured CLI.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support use of common sequence pools for non-coherent transmissions according to one or more aspects. In a first aspect, a method of wireless communication includes converting, by a wireless communication device, an information bit stream to an integer value. The method also includes selecting, by the wireless communication device, a sequence from a common sequence pool based on the integer value. The common sequence pool has a nested structure of sequences which map different length information bit streams with the same most significant bit or bits to the same sequences. The method further includes transmitting, by the wireless communication device, a non-coherent transmission indicating the sequence. Other aspects and features are also claimed and described.
