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 communication are described. Generally, the described techniques provide a base station receiving an indication from a core network to serve multicast/broadcast traffic to one or more UEs. The base station may select a radio bearer mode from a plurality of radio bearer modes for delivery of the multicast/broadcast traffic to at least one UE of the one or more UEs. For example, the base station may select a multicast/broadcast only mode, a mixed multicast/broadcast mode and unicast mode, or a unicast mode for service of the traffic. Dependent on the selected mode and/or quality of service, the base station may select a dedicated radio bearer (DRB) for communication of the traffic in a unicast mode (e.g., to a particular UE) or a multicast radio bearer (MRB) for communication of the traffic in a broadcast/multicast mode.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support uplink (UL) transmit (Tx) switch operations. In a first aspect, a method of wireless communication includes transmitting a user equipment (UE) capability that indicates multiple bands including a first set of bands and a second set of bands, each of the first set of bands and the second set of bands available for a UL Tx switch configuration. The first set of bands may be a pair of bands or a group of one or more bands. The method also includes receiving the UL Tx switch configuration for the first set of bands or the second set of bands, and transmitting an uplink message via the first set of bands or the second set of bands indicated by the UL Tx switch configuration. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications and capability signaling for enhanced handover processes are described. A user equipment (UE) may transmit, to a source base station, a band combination indicator to indicate at least one band combination supported by the UE. The source base station may transmit a source base station configuration and at least one band combination supported by the UE to a target base station for use during a handover procedure. The target base station may then transmit to the source base station, a target base station configuration to use in the handover procedure. The source base station may transmit to the UE, both base station configurations to be applied during the handover procedure which may include a number of band combinations. The UE may communicate during handover execution with both base stations using at least one band combination indicated in the received base station configurations.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may request a user equipment (UE) to report location information for the UE using a specific format. The UE may report the location information to the base station based on the request. The base station may use the location information reported by the UE to determine the location of the UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some networks, a user equipment (UE) may switch between serving beams of a transmitting device that are associated with different bandwidth parts of a radio frequency spectrum. To improve aspects of beam measurement and selection, a UE may be configured to support various techniques for beam measurement according to the different bandwidth parts. For example, a UE may receive a beam measurement configuration associated with one or more beams, and may monitor for reference signals associated with the beams using the different bandwidth parts. The UE may determine a channel quality of one or more of the beams based on the monitoring, and transmit a beam measurement report to the network in accordance with the beam measurement configuration. In some examples, such a report may be transmitted based on the UE determining that an event condition is satisfied.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a satellite of a non-terrestrial network (NTN) may establish communications on a beam of the satellite. The UE may receive, on a first carrier of a first set of carriers associated with a first beam, a configuration for the first set of carriers associated with the first beam and a second set of carriers associated with a second beam. The first carrier may be used to send a first set of synchronization signals, and a second carrier of the second set of carriers may be used to send a second set of synchronization signals. The UE may identify some system information associated with the second set of carriers based on the configuration and reselect to the second beam based on the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine an inactivity timer associated with a first set of one or more beams used for communicating with a network entity associated with a satellite has expired. The UE may identify location information corresponding to the location of the UE with respect to the network entity. The UE may identify beam geometry information for one or more beams associated with the network entity. For example, the UE may receive the beam geometry information from the network entity. The UE may process the location information and the beam geometry information to identify a second set of one or more beams, the second set different than the first set. The UE and the network entity may communicate according to the second set of one or more beams.
