    Abstract: Satellites in a non-terrestrial network may provide positioning reference signals (PRS) to user equipment (UE), with which the UE may determine its position using propagation delay difference measurements, such as Time Difference of Arrival (TDOA) measurement. Due to the large distances between satellites and the UE, the propagation delay differences in the PRS received from satellites may exceed half a radio frame, resulting in a frame level timing ambiguity in the differential measurements. The satellites transmit secondary PRS, along with primary PRS, that include timing information to resolve frame level timing ambiguity of the primary PRS. The positioning occasions in the secondary PRS, for example, may be aligned with corresponding positioning occasions primary PRS within each radio frame, and are transmitted with a periodicity that is an integer multiple (greater than 1) of that of the primary PRS to resolve the frame level timing ambiguity of the primary PRS.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a loss of coherence associated with the UE. The UE may perform at least one adjustment to a transmission parameter or a reception parameter based at least in part on the indication of the loss of coherence. For example, the adjustment to the transmission parameter may include adjusting a transmit power, adjusting a transmit frequency, adapting a transmission time, changing an antenna port, or a combination thereof. Additionally, or alternatively, the adjustment to the reception parameter may include refraining from joint channel estimation across a plurality of slots, adjusting a downscaling parameter or a frequency tuning associated with at least one reception antenna, refraining from blind decoding, or a combination thereof. Numerous other aspects are described.

    Abstract: Certain aspects of the present disclosure provide techniques for supporting multiple types of random access occasions. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), an indication of at least two types of random access occasions (ROs) including a first RO type and a second RO type for communicating in a first coverage area of the BS as part of a random access process for the UE to establish a connection with the BS in the first coverage area. The method further includes transmitting, to the BS, a preamble on an RO of one of the first RO type or the second RO type, wherein a preamble format of the preamble is based on whether the RO is of the first RO type or the second RO type.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may determine a grid allocation of single carrier resource blocks (SC-RBs) that defines a plurality of SC-RBs in a time domain and in a frequency domain. The first node may perform, to a second node, a frequency division multiplexed transmission associated with a single carrier waveform using one or more SC-RBs indicated in the grid allocation of SC-RBs. Numerous other aspects are described.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical downlink control channel (PDCCH) communication in a first dynamic control resource set (CORESET) configured in a first bandwidth part (BWP). The PDCCH communication may indicate a BWP switch from the first BWP to a second BWP. The UE may determine, based at least in part on the BWP switch, whether to monitor one or more second dynamic CORESETs, subsequent to the first dynamic CORESET, that were configured in the first BWP. The UE may selectively monitor the one or more second dynamic CORESETs based at least in part on determining whether to monitor the one or more second dynamic CORESETs. Numerous other aspects are provided.
