Abstract: Certain aspects of the present disclosure provide techniques for blind decode and control channel element counting on a secondary cell. An example method may include receiving, from a network entity, signaling configuring the UE with a search space (SS) set on a primary cell (PCell) and a common search space (CSS) set on at least a first secondary cell (SCell). The method may also include monitoring at least one of the first SCell, the PCell, or a second SCell based on a count associated with a set of candidates for the CSS set on the first SCell against a number of PDCCH candidates or a number of CCEs, the set of candidates being at least one of physical downlink control channel (PDCCH) candidates or control channel elements (CCEs).

Abstract: A base station may configure a first threshold indicating maximum numbers of blind decodes (BDs) and non-overlapping control channel elements (CCEs) for physical downlink control channel (PDCCH) candidates on a primary cell (PCell)/primary secondary cell (PSCell), and transmit, for a user equipment (UE), a configuration for PDCCH candidates in common search spaces (CSSs) or user-specific search spaces (USSs) on the PCell/PSCell and USSs on a secondary cell (SCell) for PDCCH scheduling data for the PCell/PSCell. The base station may transmit at least one PDCCH in PDCCH candidates. The UE may receive the configuration and receive the PDCCH by blindly decoding the PDCCH candidates in in at least one of the CSSs or the USSs configured on the PCell/PSCell and the USSs configured on the Scell. The USSs configured on the PCell/PSCell may support PDCCH overbooking.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, radio resource control (RRC) signaling indicating a number of padding bits in multicast downlink control information (DCI). The UE may receive, from the base station, a multicast DCI message that includes a set of fields to indicate a set of communication parameters. The UE may interpret the multicast DCI message that indicates the set of communication parameters based at least in part on the number of padding bits indicated by the RRC signaling. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for reducing a size of semistatic codebooks for HARQ feedback. A method that may be performed by a user equipment (UE) includes determining a number (M) of candidate downlink transmission occasions for a time period, determining a maximum number (k) of simultaneous downlink transmissions the UE can receive during the time period, receiving one or more downlink transmissions during the time period from a base station, and determining a type of encoding for the HARQ feedback based on: (i) a number of the one or more downlink transmissions received, (ii) the number (M) of candidate downlink transmission occasions for the time period, and/or (iii) the maximum number (k) of simultaneous downlink transmissions.

Abstract: Mechanisms for cross-carrier scheduling from a first cell to a second cell in a wireless networking scheme are provided. In one aspect, a method includes receiving, from a base station (BS), a first configuration for scheduling in a first cell having a first subcarrier spacing (SCS), wherein the first configuration is associated with a first search space in the first cell. The method further includes receiving, from the BS, a second configuration for scheduling in the first cell, wherein the second configuration is associated with a second search space in a second cell, and wherein the second cell is associated with a different second SCS. The method further includes determining a number of blind detections (BDs) based on at least one of the first SCS or the second SCS, and monitoring, based on the number of BDs, for downlink control information (DCI) in the first and second search spaces.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a timing for a reference signal measurement. The UE may measure, for a secondary cell activation procedure, a reference signal based at least in part on determining the timing for the reference signal measurement. Numerous other aspects are provided.

Abstract: A base station may transmit a multicast transmission to a group of user equipments (UEs) that are each configured with a group radio network temporary identifier (G-RNTI). The UEs may be configured to receive the transmission using the same modulation and coding scheme (MCS) and transport block size (TBS) such that the group of UEs may receive the same transmission. In particular, a UE may receive one or more configurations for multicast transmissions, each configuration associated with a G-RNTI. The UE may determine a MCS table for the G-RNTI. The UE may determine a TBS for a multicast transmission based on an overhead value for the G-RNTI. The UE may receive the multicast transmission based on the MCS table and the TBS.

Abstract: Aspects described herein relate to retransmission implementations in new radio (NR) wireless communication systems. In one aspect, a network entity may initially perform a multicast transmission and then a multicast retransmission according to a hybrid automatic repeat request (HARQ) process. In another aspect, a user equipment (UE) may initially receive a multicast transmission from a network entity and a subsequent multicast transmission according to a HARQ process. In an additional aspect, a network entity may initially perform a multicast transmission and then a subsequent unicast retransmission according to a HARQ process. In yet another aspect, a UE may initially receive a multicast transmission from a network entity and a subsequent unicast transmission according to a HARQ process.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a first cell, downlink control information for physical downlink control channel ordered contention-free random access, wherein the downlink control information indicates a timing advance group of a second cell and one or more parameters associated with a random access message to be transmitted by the UE via the second cell, wherein the first cell and the second cell belong to different timing advance groups. The UE may transmit the random access message via the second cell according to the one or more parameters and a timing advance value determined based at least in part on the timing advance group of the second cell. Numerous other aspects are provided.
