Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARQ) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate over multiple component carriers (CCs). The UE may receive control signaling indicating a joint feedback codebook configuration for jointly reporting feedback for a first CC, a second CC, and a virtual CC that may be mapped to a third CC and a fourth CC. The UE may then receive downlink control information (DCI) scheduling a first downlink transmission via the first CC and a second downlink transmission on the second CC, or both downlink transmissions may be scheduled via the virtual CC. The UE may transmit a joint feedback message for the first CC, the second CC, and the virtual CC based on the joint codebook configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive a configuration message identifying a set of resources available for a plurality of UEs for transmission of feedback indications of multi-cast (or broadcast) transmission to the plurality of UEs, the set of resources comprising a plurality of subsets of resources, each subset of resources being associated with a corresponding channel metric for each UE of the plurality of UEs. The UE may determine that a feedback indication is to be provided in response to the multi-cast transmission. The UE may select, based at least in part on a channel metric of the UE, a first subset of the plurality of subsets of resources to use for transmitting a feedback message including the feedback indication. The UE may transmit the feedback message for the multi-cast transmission using resources within the selected first subset of resources.

Abstract: Aspects of this disclosure provide methods, devices and systems for concurrently transmitting control information and data information. In some more specific aspects, a base station may transmit one or more parameters to a user equipment (UE) that indicate to the UE to refrain from transmitting uplink control information together with uplink data information in an uplink data channel. Instead, the one or more parameters may configure the UE to transmit the uplink control information and the uplink data information using overlapping resources in different channels. In some more specific aspects, the UE may transmit the uplink control information in a slot of an uplink control channel and transmit the uplink data information in a slot of the uplink data channel that at least partially overlaps with the slot of the uplink control channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a single downlink control information (DCI) message that schedules communications on multiple cells, wherein the single DCI message indicates multiple time domain resource assignments (TDRAs) corresponding to the multiple cells, wherein each of the multiple TDRAs corresponds to a different scheduled communication; and communicate using the multiple TDRAs corresponding to the multiple cells, wherein the communicating comprises: transmitting the communications using the multiple TDRAs corresponding to the multiple cells, or receiving the communications using the multiple TDRAs corresponding to the multiple cells. Numerous other aspects are provided.

Abstract: Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a physical uplink control channel (PUCCH) format and a PUCCH resource to be used for concurrently transmitting hybrid automatic repeat request (HARQ) feedback and additional uplink control information based at least in part on downlink control information including a downlink assignment index equal to one. The UE may transmit one or more of the HARQ feedback or the additional uplink control information using the PUCCH format and the PUCCH resource. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encored on computer storage media, for fifth generation (5G) - new radio (NR) physical layer (PHY) timing synchronization. In one aspect, a user equipment (UE) computing device may determine a new timing advance (TA) between downlink frames and uplink frames (NTA_new) for a base station (BS) and determine whether the NTA_new may be within a timing advance acceptable range. In another aspect, a BS may determine a timing advance command (TA ) for a timing advance group (TAG) for the BS, and send the TA to the UE computing device. In determining the timing advance command, the TA may be configured by the BS to cause the UE computing device to determine that a new timing advance between downlink frames and uplink frames (NTA_new) for the BS using the TA is within a timing advance acceptable range.

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: 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 multiplication factor. Further, the UE may determine a limit of a number of serving cells based on the capability and a configuration of serving cells. The UE may determine a total limit of PDCCH candidates and non-overlapped control channel elements (CCEs) to monitor in a slot for a cell group and a per cell limit single TRP cells and for multiple TRP cells based on the limit of the number of serving cells. Alternatively, the limits may be defined per control resource set (CORESET) group.
