Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message from a base station that schedules multiple transport blocks (TBs) to be transmitted to the UE. Accordingly, the UE may determine a bundling configuration for grouping the multiple TBs into separate groups of TBs such that separate acknowledgment (ACK) feedback messages are transmitted by the UE for each group of TBs to indicate whether each of the TBs in each TB group was correctly received and decoded. In some cases, the UE may determine the bundling configuration based on radio resource control signaling from the base station, DCI signaling from the base station, relationships or equations or tables defined for the UE, or a combination thereof. Additionally, the UE may determine resource locations and timelines for transmitting the separate ACK feedback messages.

Abstract: An apparatus may be configured to communicate at least one pilot signal with another apparatus according to a first configuration, at least one of a lower frequency density or a higher time density being indicated by the first configuration than a second configuration for a type of pilot signal that includes the at least one pilot signal. The apparatus may be further configured to communicate with the other apparatus based on the at least one pilot signal. Another apparatus may be configured to receive, from a base station, spatial relationship information or transmission configuration indicator (TCI) state information corresponding to a directional beam at the UE for communication on a channel. The apparatus may be further configured to apply the directional beam for communication with the base station on another channel in a sub-6 gigahertz (GHz) frequency band.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive broadcast information from a base station indicating a numerology or a reference signal (RS) pattern to be used in broadcast or multicast transmissions (e.g., a physical multicast channel (PMCH)). The UE may identify a modulation and coding scheme (MCS) associated with the broadcast or multicast transmission and may determine a transport block size (TBS) based on the MCS and at least one of the numerology or the RS pattern. For instance, a UE may determine TBS for numerologies associated with a single symbol that spans multiple subframes differently from that of other numerologies. Additionally or alternatively, a UE may determine TBS for sparse RS patterns differently from that of other RS patterns. The UE may then perform communication with the base station via the broadcast or multicast transmissions in accordance with the TBS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a quantity of downlink control information (DCI) sizes, for a set of DCIs that the UE is to monitor and that includes a multicast DCI, satisfies a size threshold. The UE may perform a DCI size alignment procedure to adjust a DCI monitoring configuration. The UE may monitor for the set of DCIs based at least in part on performing the DCI size alignment procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine timing misalignment information for a timing misalignment between an uplink timeline and a downlink timeline associated with a non-terrestrial cell. The UE may transmit the timing misalignment information to a satellite associated with the non-terrestrial cell. Numerous other aspects are described.

Abstract: This disclosure relates to techniques for providing access control for multicast or broadcast (MC/BC) services. A base station broadcasts one or more cell barring parameters to a group of user equipment (UEs) that indicate whether the UEs of the group of UEs is permitted to select the cell of the base station for receiving the MC/BC services. The base station also broadcasts one or more access control parameters to a set of one or more UEs, of the group of UEs, that are indicated to be permitted to select the cell for receiving the MC/BC services based on the one or more cell barring parameters. The one or more access control parameters indicate whether the set of one or more UEs is permitted to establish or resume the RRC connected state with the base station for receiving the MC/BC services.

Abstract: The present disclosure relates to methods and devices for flexible resource allocation. In one aspect, a base station can generate a narrowband data channel including a plurality of resource blocks (RBs). The base station may shift a position of the RBs of the narrowband data channel to align with a wideband resource block group (RBG) boundary. The base station can also adjust a precoding resource block group (PRG) for the narrowband data channel. Also, the base station can transmit the narrowband data channel to a User Equipment (UE) based on adjusting the PRG. In another aspect, the base station may align a beginning or last RB of the plurality of RBs with the wideband RBG boundary and/or align a beginning or last RB of the PRG with the wideband RBG boundary. In another aspect, the base station may transmit an indication to the UE indicating a flexible resource allocation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for an orthogonal frequency division (OFDM) symbol that includes one or more cell-specific reference signal (CRS) resource elements and one or more narrowband physical downlink shared channel (NPDSCH) resource elements, an NPDSCH energy per resource element (EPRE), wherein the NPDSCH EPRE for the OFDM symbol is based at least in part on an EPRE differential between a narrowband reference signal (NRS) EPRE and a CRS EPRE. The UE may demodulate the OFDM symbol based at least in part on the NPDSCH EPRE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) frequency hopping enhancements. An example method performed by user equipment generally includes determining a first sounding reference signal (SRS) frequency hopping pattern for transmitting one or more SRSs; determining an antenna switch will occur during the transmission of the one or more SRSs; determining a second SRS frequency hopping pattern for transmitting the one or more SRSs, wherein determining the second SRS frequency hopping pattern comprises using the first SRS frequency hopping pattern to generate the second SRS frequency hopping pattern based on the determined antenna switch; and transmitting a first set of SRSs of the one or more SRSs according to the first SRS frequency hopping pattern and transmitting a second set of SRSs of the one or more SRSs according to the second SRS frequency hopping pattern.
