Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, an indication of a physical downlink control channel (PDCCH) processing unit (PPU) limit associated with the UE. The UE may receive configurations for a plurality of search space sets, wherein the plurality of search space sets includes one or more linked pairs of search space sets with linked PDCCH candidates for PDCCH repetition. The configurations of the one or more linked pairs of search space sets may be based at least in part on the PPU limit associated with the UE. Numerous other aspects are described.

Complexity handling for physical downlink control channel repetition

Aspects of the present disclosure provide techniques for channel state information (CSI) reporting in multiple transmitter receiver point (mTRP) scenarios.

Methods for PMI, RI and port indexing of CSI for multiple transmitter receiver points

A user equipment may receive a first physical uplink shared channel (PUSCH) configuration and a second PUSCH configuration. The user equipment may transmit a first uplink communication and a second uplink communication using different antenna panels, based at least in part on the first PUSCH configuration and the second PUSCH configuration.

Multiple uplink configurations for multiple antenna panel transmissions

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor search spaces on a primary cell and an secondary cell in a carrier aggregation configuration. The UE may monitor the search spaces for control information according to a shared search space monitoring configuration. Based on the shared search space monitoring configuration, the UE may identify that the secondary cell is a scheduling cell and the primary cell is a scheduled cell (e.g., cross-carrier scheduling). The UE may monitor control channel candidates of search spaces on the primary cell and on the secondary cell for downlink control information messages scheduling data transmissions with the primary cell. In some examples, the cross-carrier scheduled communications may be configured according to a scheduling configuration, which may include one or more scheduling constraints.

Techniques for cross-carrier scheduling from a secondary cell to a primary cell

Methods, systems, and devices for wireless communications are described. A receiving device may receive (e.g., from a transmitting device) one or more control messages indicating a first physical resource block (PRB) bundling size for a first set of two or more layers of a downlink shared channel and a second PRB bundling size for a second set of two or more layers of the downlink shared channel. The receiving device may receive a downlink transmission (e.g., a downlink shared channel transmission) that includes multiple codewords, such as a first codeword corresponding to the first set of two or more layers and a second codeword corresponding to the second set of two or more layers. The receiving device may receive the downlink transmission and may decode each codeword based on one or more channel estimates using the first PRB bundling size and the second PRB bundling size.

Unequal precoding resource block group sizes for multiple-codeword downlink data transmissions

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support monitoring for intra-slot and intra-slot-group control channel repetitions. The UE may receive a message indicating a respective set of parameters for a first search space set and a second search space set, an indication that the first and second search space sets are linked, and a respective bitmap for each of the search space sets, where the bitmaps include a same quantity of bits. The bitmaps may indicate a quantity of slots and a location of the slots within a group of slots in which a respective search space set exists within the group of slots. As such, the UE may monitor the first and second search space sets based on the respective sets of parameters and the respective bitmaps (e.g., using monitoring occasions associated with each search space set linked based on the bitmaps).

Control channel repetition for higher bands

Determining, by a user equipment (UE) of a wireless communication system, that a physical uplink control channel (PUCCH) transmission of the UE carrying uplink control information (UCI) will collide upon transmission with another physical uplink shared channel (PUSCH) transmission of the UE. The UE then multiplexes, in response to the determining, the UCI on the PUSCH transmission based on one or more of the beam of the PUCCH transmission and the beam of the particular PUSCH transmission.

Uplink control information multiplexing

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station during a physical downlink control channel (PDCCH) monitoring occasion (PMO), first downlink control information (DCI) scheduling the UE for a first physical downlink shared channel (PDSCH) resource on a first component carrier and for a second PDSCH resource on a second component carrier. The UE may receive, during the PMO, second DCI scheduling the UE for a third PDSCH resource on the second component carrier. The UE may identify a set of downlink assignment indices (DAIs) for the first DCI and the second DCI, where the first DCI has one or more DAIs whose values are based on the first DCI scheduling PDSCH resources on different component carriers. The UE may transmit feedback based on the set of DAIs.

Feedback schemes for multiple component carrier scheduling and joint feedback reporting

In some implementations, a method of wireless communication includes selecting, at a user equipment (UE), one or more control resource sets (CORESETs) from a plurality of CORESETs corresponding to the UE. At least one of the plurality of CORESETs corresponds to multiple active transmission configuration indicator (TCI) states. The method further includes performing a radio link monitoring (RLM) operation, a beam failure detection (BFD) operation, or both, based on one or more reference signals (RSs) corresponding to active TCI states associated with the one or more selected CORESETs.

A first UE may be configured to receive a common message associated with the first UE and at least one second UE. The first UE may be configured to obtain a common message configuration having at least one of a first indicator for a first data portion of the common message associated with the first UE or at least one second indicator for at least one second data portion of the common message associated with the at least one second UE. The common message configuration may be obtained from at least one of a header of the common message or DCI scheduling the common message.

A configuration to allow a UE to determine if a detected PDCCH corresponds to a linked PDCCH candidate with repetition. The apparatus monitors for a PDCCH based on a DRX configuration, the DRX configuration having an inactivity timer. The apparatus determines whether the PDCCH corresponds to a linked PDCCH candidate and a new transmission is scheduled, wherein the linked PDCCH candidate is comprised of two or more PDCCH repetitions. The apparatus starts the inactivity timer in a first symbol after an end of at least one of the two or more PDCCH repetitions.

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 that the UE is capable of transmitting or receiving transport block (TB) repetitions using spatial division multiplexing (SDM). The UE may receive, from the base station and based at least in part on the indication, at least one downlink control information (DCI) message that schedules a TB in a first resource and a repetition of the TB in a second resource, the first resource and the second resource at least partially overlapping in a time domain and a frequency domain. The UE may communicate the TB and the repetition of the TB using different antenna panels according to the at least one DCI message. Numerous other aspects are provided.
