Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain an indication that a difference between a previous timing advance value that is based at least in part on a current satellite location and a previous combination of a UE location and a timing advance parameter, and a current timing advance value that is based at least in part on the current satellite location and a current combination of the UE location and the timing advance parameter, is greater than a threshold. The UE may generate an adjusted timing advance value that is different from the current timing advance value by an amount that is less than the threshold. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques for uplink (UL) data channel design. An example method is provided for operations which may be performed by a first apparatus. The example method generally comprises determining a number of pilot symbols to transmit for one or more slots of a first subframe based, at least in part, on a coverage enhancement (CE) level, and transmitting at least one uplink data channel having the determined number of pilot symbols in the one or more slots of the first subframe.

Abstract: Methods, systems, and devices for wireless communications are described. In some non-terrestrial networks, the movement of satellites may result in the movement of cell coverage. A user equipment (UE) may experience changing cell coverage due to the movement of cell coverage, even if the UE is stationary. A UE may be configured to determine a cell is serving two or more earth-fixed tracking areas, determine whether to monitor paging resources of a first earth-fixed tracking area or a second earth-fixed tracking area, and monitor the selected paging resources. In some aspects, the UE may determine that a cell serves two or more earth-fixed tracking areas based on a received control message including multiple tracking area indicators. In some aspects, the UE may determine which paging resources to monitor based on a geographic position of the UE.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for pilot design for Narrow-Band Internet of Things (NB-IoT). In certain aspects, the method generally includes determining at least one binary code sequence to use as a demodulation reference signal (DMRS) for a channel transmitted across one or more subframes using one or more tones within a resource block (RB) allocated to the UE for narrowband communication, and transmitting the channel including the DMRS using the one or more tones and the determined binary code sequence. In certain aspects, the binary code sequence may be determined based on a binary random sequence, such as pseudo noise (PN) or Gold sequence.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, signaling indicating one or more common timing offset parameters that are based at least in part on one or more delays between a satellite and a reference point in a non-terrestrial network (NTN). The UE may determine a transmit time for an uplink signal based at least in part on the one or more common timing offset parameters and a starting time associated with an uplink slot in which the uplink signal is to arrive at the reference point. The UE may transmit the uplink signal at the transmit time. 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 information that indicates whether to perform a first random access channel (RACH) procedure for a non-terrestrial network or a second RACH procedure for a terrestrial network, wherein the first RACH procedure is configured to support a larger number of UEs contemporaneously performing a RACH procedure than the second RACH procedure. Responsive to the information indicating that the UE is to perform the first RACH procedure, the UE may perform the first RACH procedure. Numerous other aspects are provided.

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 method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. A BS and a UE may communicate using a narrowband Internet of Things (NB-IoT) communication system. However, a frequency, time, and/or power associated with transmission of a SIB1-NB on a non-anchor carrier may not be configured for NB-IoT. In some aspects, the BS may determine parameters, such as a time domain location parameter, a frequency domain location parameter, a quantity of repetitions, a power boosting parameter, and/or the like for a transmission in NB-IoT. In some aspects, a UE may determine to transmit a connection request message on a different carrier than a random access channel message.
