Abstract: Disclosed are techniques for positioning. A receiver receives complementary timing information associated with the positioning reference signals (PRS) of a repetition of a PRS sequence. The complementary timing information distinguishes a repetition of a PRS sequence from remaining repetitions of the PRS sequence. Based on the complementary timing information associated with different PRS from different non-terrestrial vehicles indicating that the PRS were transmitted during the same radio frame, the receiver can determine an observed time difference of arrival (OTDOA) between the PRS received from the respective non-terrestrial vehicles.

Abstract: A base station may identify one or more beams toward a node for communication with at least one UE. The one or more beams may correspond to a plurality of beams from the node. The base station may transmit, to the node, an indication to adjust a surface phase of the node corresponding to the one or more beams or one of the plurality of beams from the node. The base station may select at least one beam of the plurality of beams from the node for communication with the at least one UE. The base station may communicate with the at least one UE via the node and the at least one beam. The at least one beam of the plurality of beams from the node may be based on a defocusing operation associated with a virtual focal point.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, an indication of a time gap value associated with a random access channel (RACH) procedure, wherein the time gap value is based at least in part on a capability of the base station, determine whether a physical RACH (PRACH) occasion associated with the RACH procedure is valid based at least in part on receiving the indication of the time gap value associated with the RACH procedure, and selectively transmit, to the base station, a PRACH transmission in the PRACH occasion based at least in part on determining whether the PRACH occasion is valid. Numerous other aspects are provided.

Abstract: A UE, as a part of a RACH communication procedure, may transmit a first sequence within a first set of resources having a first SCS and a second sequence within a second set of resources having a second SCS greater than the first SCS. The second sequence is transmitted with a cyclic prefix greater than inverse of the first SCS divided by a sequence length of the first sequence. The first sequence is a first PRACH preamble. The second sequence may be a second PRACH preamble, an SRS sequence, or DMRS. The UE may repeat the transmission of the first sequence for a first number of times and repeat the transmission of the second sequence for a second number of times independent of the first number.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a number of resource elements (REs) associated with downlink control information (DCI) that is to be carried on a physical downlink shared channel (PDSCH) with a shared channel, wherein the number of REs associated with the DCI is determined based at least in part on a scaling factor and a number of REs associated with the shared channel; determine a transport block size (TBS) for the shared channel based at least in part on a remaining number of REs, of the number of REs associated with the shared channel, wherein the remaining number of REs is based at least in part on the number of REs associated with the DCI; and receive the PDSCH based at least in part on the TBS for the shared channel. 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 receive, in a single dynamic signaling communication, an indication to activate one or more coverage enhancement parameters. The UE may activate the one or more coverage enhancement parameters based at least in part on receiving the indication. Numerous other aspects are provided.

Abstract: A method of wireless communication by a UE (user equipment) includes receiving group-common downlink control information (DCI) indicating coverage-enhancements including channel state information (CSI) report settings for a group of UEs and/or PDCCH repetition. The method also includes reporting CSI in accordance with the coverage-enhanced CSI report settings, which may include report repetition. A method of wireless communication by a base station includes transmitting group-common downlink control information (DCI) indicating coverage-enhanced channel state information (CSI) report settings and/or PDCCH repetition for a group of UEs. The method also includes receiving CSI reports from the group of UEs in accordance with the group-common DCI.

Abstract: Orthogonal frequency-division multiplexing (OFDM) numerologies that maintain symbol boundary alignment while distributing excess cyclic prefixes (CPs) among OFDM symbols. Communication is established using a first sub-carrier spacing (SCS) and a first OFDM numerology, such as an exemplary numerology that distributes excess CP duration among a set of symbols that occupy a time interval within or equal to a corresponding time interval of a symbol of a second OFDM numerology with a second lower SCS. The first SCS may be, e.g., 960 kHz. The second SCS may be, e.g., 120 kHz. Another exemplary OFDM numerology described herein distributes the excess CP as prefix and postfix portions to one of the symbols, such as the first symbol of a set. Communication then proceeds using the first OFDM numerology at the first SCS and, in illustrative examples, using the second OFDM numerology at the second SCS or other OFDM numerologies at other SCSs.

Abstract: A non-geosynchronous satellite system, where each satellite has an antenna (perhaps a multi-element antenna) to form a beam pattern comprising a set of beams in the footprint of the satellite, where in one implementation each beam is substantially elliptical in shape having a minor axis and a major axis, where the minor axes are substantially collinear and the major axes are substantially oriented east to west. For a satellite, power is reduced or turned off for a subset of the set of beams, wherein each beam in the subset is reduced at or below a corresponding power level such that when a beam is powered above its corresponding power level an equivalent power flux-density (EPFD) exceeds a limit at some point on the Earth's surface.
