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: Wireless communications devices and methods are adapted to facilitate DMRS sequence grouping. In one example, information is obtained for a transmission scheduled with pi/2 BPSK modulation, the transmission including two or more symbols scheduled for a DMRS (DMRS symbols). Respective DMRS sequences may be identified for each of the DMRS symbols, where each DMRS sequence subsequent to another DMRS sequence is dependent on its immediately preceding DMRS sequence, and the transmission may be sent with the identified DMRS sequences in the two or more DMRS symbols. In one example, a first transmission may be sent to schedule a second transmission from another device with pi/2 BPSK modulation, where the second transmission includes two or more DMRS symbols. The scheduled second transmission may be received with at least one DMRS symbol including a DMRS sequence based on its immediately preceding DMRS sequence. Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a first set of grants for performing uplink transmissions between the UE and a first group of cells associated with a first radio access technology (RAT) and a second set of grants for performing uplink communication between the UE and a second group of cells associated with a second RAT. The UE may determine that a combined transmit power exceeds a total power limit or that there may be a potential of the combined power exceeding the total power limit. The UE may further perform the uplink communication with the first group of cells using the first RAT and the second group of cells using the second RAT.

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: A method, apparatus, and computer-readable medium are provided for wireless communication at a Road Side Synchronization Device (RSSD). The RSSD receives, from a first neighbor device, a first Sidelink Synchronization Signal (SLSS). The RSSD synchronizes in time/frequency with the first neighbor device, and transmits a second SLSS. The second SLSS is based on a synchronized timing and a synchronized frequency with the first neighbor device.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A narrowband internet of things (NB-IoT) user equipment (UE) associated with a non-terrestrial wireless network may identify a first synchronization procedure that is specific to the non-terrestrial network and different from synchronization procedures specific to terrestrial networks. In some cases, the UE may identify a different channel raster or may receive an indication of a true frequency of operation of a narrowband cell in the non-terrestrial network. The UE may identify the narrowband cell associated with the non-terrestrial network and may synchronize with the network using the identified synchronization procedure.

Abstract: Methods, systems, and devices for wireless communications are described that provide for managing transmissions using multiple component carriers (CCs) in which transmissions using one or more of the CCs may span less than a full transmission time of a slot or other transmission time interval. A UE may signal a capability to transmit such transmissions, and one or more capabilities related to carrier aggregation that may be used by a base station for scheduling of transmissions on different CCs. In the event that overlapping transmissions on two or more CCs exceed a maximum power threshold, various techniques for dropping at least a portion of one or more transmissions of one or more CCs are described.

Abstract: Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions. In some cases, a UE may determine a transmit power budget, receiving signaling indicating how to allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, and transmitting the PUSCH using the transmit chains according to the determined transmit power allocation.
