Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying a configuration of a set of uplink slots for the UE to transmit uplink reference signals to a satellite. The UE may transmit, to the satellite, a set of uplink reference signals on the set of uplink slots according to the configuration. The set of uplink reference signals may include sounding reference signals (SRSs), positioning references signals (PRSs), or both. In some implementations, the UE may transmit the set of uplink reference signals in accordance with one or more timing advance values, where the timing advance values are indicated to the satellite by the UE, pre-configured by the satellite, or both. The UE may then, from a network node, an indication of a position of the UE based on the set of uplink reference signals.

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: A base station may transmit a broadcast/multicast service in a multicast broadcast single frequency network (MBSFN) area multicast communication. A method of wireless communication at a base station in accordance with an aspect of the present disclosure comprises determining a broadcast/multicast service to be provided to a user equipment (UE) in a multicast broadcast single frequency network (MBSFN) area, and transmitting a tracking reference signal (TRS) to the UE, the TRS indicating information associated with receiving the broadcast/multicast service by the UE.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

Abstract: Wireless communication systems and methods related to determining a new multimedia broadcast multicast service (MBMS) configuration for a MBMS that is backward compatible with a legacy MBMS configurations. A base station determines a MBMS configuration. The MBMS configuration includes at least one non-optional field that indicates compatibility with a first user equipment (UE) having a first MBMS capability or compatibility with a second UE having a second MBMS capability. The MBMS configuration also includes a sub-carrier spacing indication for a MBMS corresponding to the first MBMS capability or the second MBMS capability. The MBMS configuration is broadcasted to the first UE and the second UE.

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 serving base station or a serving satellite may transmit a timing configuration to the UE based on a reference unit, such as a location at a beam center for a respective satellite, a threshold distance relative to the beam center for the respective satellite, a reference time, or any combination thereof. In some cases, the UE may monitor for one or more SSBs from the neighboring satellites according to the timing configuration and a respective propagation delay between the UE and each of the neighboring satellites. The UE may measure the SSBs according to the measurement gap and measurement window in the timing configuration. In some examples, the UE may perform a cell handover procedure or a cell reselection procedure based on measuring the SSBs.

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: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may identify information for transmitting to a base station of a non-terrestrial network. The UE may identify that one or more resources allocated for transmitting the information are available based at least in part on identifying the information. The one or more resources include one or more types of uplink resources including physical random access channel (PRACH) resources or physical uplink shared channel (PUSCH) resources for the random access procedure, a PUSCH for a scheduling request (SR), or a physical uplink control channel (PUCCH) for a configured grant, or a combination thereof As a result, the UE may transmit, to the base station, a message over the one or more resources allocated for the information based at least in part on identifying the one or more resources.
