    Abstract: Since multiple transmit-receive point (TRP) communications may increase the number of physical downlink control channel (PDCCH) candidates without increasing the number of cells, new limits for multi-TRP communications may be defined. A UE may determine a PDCCH monitoring capability across all downlink serving cells that may account for multiple-TRP cells and for carrier aggregation and dual connectivity using a a monitoring capability for a first control resource set (CORESET) group and a second CORESET group. Further, the UE may determine limits of a number of serving cells based on the capability and a configuration of serving cells. The UE may determine a total limit and a per cell limit of PDCCH candidates and non-overlapped control channel elements (CCEs) to monitor in a slot for a cell group for the first CORESET group and for the second CORESET group. The UE may perform blind decoding operations within the limits.

    Abstract: Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving first downlink (DL) control information (DCI) for scheduling resources in time in a system frame for transmission of one or more uplink (UL) data channels and hybrid automatic request (HARQ) signaling for acknowledging whether one or more downlink data channels have been successfully decoded, the one or more UL data channels and the HARQ signaling being configured based on a UL to DL resource ratio associated with a time-division duplex (TDD) subframe configuration. In certain aspects, the UE generates the one or more UL data channels and the HARQ signaling, and transmits the UL data channels and the HARQ signaling using the scheduled resources and in accordance with the TDD subframe configuration.

    Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing cross-carrier scheduling by a processor of a wireless device. In one aspect, a wireless device may determine that a scheduled cell is configured to be scheduled by a scheduling cell. The wireless device may receive downlink control information (DCI) from a scheduling cell. The wireless device may determine an association of the DCI and an index based on the received DCI. The wireless device may perform cross-carrier scheduling of communications with a first transmit-receive point (TRP) or a second TRP based on the DCI and the associated index.

    Abstract: Support for multicast and broadcast data transmissions and acknowledgement feedback for the transmissions are being considered in 5G new radio (NR). Resource allocation techniques are provided to allocate uplink control channel resources for acknowledgement of downlink multicast/broadcast (MC/BC) data transmissions. An apparatus, such as a user equipment, receives a multicast/broadcast (MC/BC) configuration indicating a first physical uplink control channel (PUCCH) resource set for transmitting MC/BC acknowledgment (ACK)/negative acknowledgment (NACK), and a unicast configuration indicating a second PUCCH resource set for transmitting unicast ACK/NACK feedback. The apparatus also receives MC/BC data from a base station. The apparatus determines a first PUCCH resource from the first PUCCH resource set for transmitting MC/BC ACK/NACK feedback in response to the received MC/BC data and based on the received MC/BC configuration. The apparatus transmits the MC/BC ACK/NACK feedback to the base station in the determined first PUCCH resource.

    Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives a set of configuration parameters related to a hybrid automatic repeat request (HARQ) acknowledgement (ACK) codebook from a network entity, and identifies an operating state for each component carrier (CC) of multiple CCs associated with the UE based on the set of configuration parameters. The UE further allocates one or more entries of the HARQ ACK codebook based on the operating state for each CC of the multiple CCs, and transmits the HARQ ACK feedback associated with the one or more entries of the HARQ ACK codebook to the network entity.
