Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A device may receive a set of demodulation reference signals (DMRSs) over a multi-path channel on a set of resources in accordance with a reference signal pattern. The reference signal pattern may be associated with a non-uniform frequency spacing that results in a row-sampled Discrete Fourier Transform (DFT) matrix associated with the reference signal pattern having a lower coherence than other row-sampled DFT matrices. Additionally or alternatively, the device may receive a set of tracking reference signals (TRSs) over the multi-path channel. The set of TRSs may be specific to wide-area terrestrial broadcast services, single frequency network (SFN)-based broadcast services, multimedia broadcast multicast services (MBMSs), or the reference signal pattern. The device may perform channel estimation based on receiving one or both of the set of DMRSs or the set of TRSs over the multi-path channel.

Abstract: Certain aspects of the present disclosure provide techniques for providing feedback. For example, a user equipment (UE) may receive, from a network node, a configuration of a search space comprising time and frequency resources available to the network node for communicating a downlink control channel, the configuration indicating a feedback process type corresponding to the search space. The UE may also receive, from the network node, the downlink control channel in the search space. The UE may also receive a downlink transmission scheduled by the downlink control channel. The UE may selectively provide feedback to the network node regarding decoding of the downlink transmission according to the feedback process type corresponding to the search space.

Abstract: In one aspect, a method of wireless communication includes operating, by a user equipment (UE), in a network with fixed radio cells. The method also includes determining, by the UE, a plurality of potential satellites for selecting a first cell to camp on, the first cell associated with a first satellite. The method includes performing cell reselection, by the UE, to select a cell associated with a second satellite using a selection condition. The method further includes establishing, by the UE, a connection with the second satellite for paging monitoring or wireless communications. Other aspects and features are also claimed and described.

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 which UEs may communicate with satellites or base stations, or both in a non-terrestrial network. Due to large distances between transmitting devices and receiving devices in a non-terrestrial network, the UE may account for propagation delay and frequency shift of communications with a satellite based on location information of the satellite. The UE may receive first satellite location information from a base station or a satellite, via a broadcast message. The UE may receive second satellite location information from the wireless network node via a unicast message, where both the first satellite location information and the second satellite location information relate to a same satellite. The UE may transmit an uplink communication via the satellite based on at least one of the first satellite location information or the second satellite location information.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may indicate in system information, or a user equipment (UE) may determine based on system information, which reference signal resources may be used for channel estimation for a given broadcast control channel. In some examples, a base station may configure and transmit reference signals having the same numerology as a broadcast control channel according to a first reference signal pattern during the same subframe in which the broadcast control channel is configured. The first reference signal pattern may be more dense than a second reference signal pattern used for reference signals having a different numerology than the broadcast control channel. The more dense first reference signal pattern may provide sufficient reference signals for successful single-symbol channel estimation, resulting in a successful decoding of the broadcast control channel.
