Abstract: Aspects presented herein may enable a remote UE to notify a base station about the availability of a relay UE that is not connected to the base station. In one aspect, a remote UE transmits, to a relay UE, a relay request via sidelink, the relay UE being in an RRC inactive mode. The remote UE receives, from the relay UE via the sidelink, an indication of relay availability in response to the relay request. The remote UE receives, from a base station, a configuration for relay of communication from the base station over the sidelink between the remote UE and the relay UE. The remote UE transmits or receives user data from the base station through the relay UE based on the configuration.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for UW-OFDM waveform techniques. A UE may receive, from a base station, an indication of one or more parameters for the UW-OFDM waveform. The UE may subsequently receive, from the base station, a downlink transmission having the UW-OFDM waveform based on the one or more parameters. A location of redundant subcarriers for the UW-OFDM waveform may be based on at least one of frequency resources allocated for the UE or a combination of the frequency resources allocated to multiple UEs.

Abstract: Aspects relate to techniques for configuring intermittent time domain resources that are usable by a user equipment (UE) for communication with a base station. The base station may transmit a usable time domain resource (TDR) configuration to the UE that indicates the usable time resources that are available to the UE for communication with the base station. The UE may then communicate with the base station based on the usable TDR configuration.

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: In a wireless network, a frame structure may include a padding duration at the start of every half subframe to ensure that an integer number of symbols fit within a duration of the half subframe. In some aspects, to avoid wasting time domain resources, the padding duration may be utilized for other purposes. For example, because a single carrier waveform is not bound to a fixed Fast Fourier Transform size, a wireless node may use the padding duration to transmit a single carrier symbol that has a shorter length than a full symbol associated with a subcarrier spacing. Additionally, or alternatively, in cases where a wireless node is configured to transmit or receive a signal in a first symbol of a half subframe that is associated with a different power level than a preceding symbol, the padding duration may be used to adapt a transmit power or a receive gain.

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.
