Abstract: Techniques for improving the capacity of a wireless communications system using interference cancellation (IC). In an early decoding and IC aspect, a frame transmitted from a user to a base station may be decoded prior to the entire frame being received by the base station. The remaining portion of the frame may then be re-constructed at the base station prior to its reception, and cancelled from the receive signal to reduce the interference to frames received from other users. In a power control aspect for early decoding and IC, the power control target level at a local base station may be adjusted in response to successfully early decoding a frame, without affecting the overall outer loop power control operation. Further aspects include late decoding techniques for utilizing the IC of other users' signals to improve the probability of decoding a given user's frames, as well as techniques for traffic channel demodulation using channel re-estimation.

Abstract: A UE determines a group identifier based at least in part on a timing advance (TA) associated with the UE, the group identifier associated with at least the UE and a second UE and receives a sidelink resource allocation associated with the group identifier. The UE transmits sidelink communication using the sidelink resource allocation. A network node associates a UE with a group identifier based on a timing advance (TA) associated with the UE and transmits a sidelink resource allocation associated with the group identifier, the group identifier associated with at least the UE and a second UE.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms for non-coherent, sequence-based downlink control signaling in a wireless communication system. In aspects, the mechanisms for non-coherent, sequence-based downlink control signaling may include a new non-coherent, sequence-based downlink control channel or signal transmitted from a base station to a user equipment (UE) and configured to convey information bits (e.g., control information bits) to the UE. The UE may receive a signal transmitted over the new non-coherent, sequence-based downlink control channel and may decode the signal to extract the control information. The UE may then apply a control based on the control information received from the base station in the signal over the non-coherent, sequence-based downlink control channel.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for demodulation reference signal (DMRS) precoding in high-Doppler scenarios. In some aspects, communicating devices may support different precodings for different portions of a signal, such as for a DMRS portion and an information portion. For example, a device may receive a signal including an orthogonal time-frequency space (OTFS) precoded first waveform portion carrying DMRS symbols and an orthogonal frequency division multiplexing (OFDM) precoded second waveform portion carrying information symbols. The device may transform the OTFS precoded DMRS symbols from a time-frequency domain to a delay-Doppler domain, may use the DMRS symbols to estimate a delay-Doppler channel, and may use the delay-Doppler channel estimate to measure an inter-carrier interference (ICI). The receiving device may use the ICI measurement to receive the information symbols carried by the OFDM precoded second waveform portion.

Abstract: Methods, systems, and devices for wireless communications are described that support techniques for intra-satellite handover. The described techniques provide for handovers such that a user equipment (UE) may transition from communications with a satellite via a first frequency (or set of frequencies) to communications with the same satellite via a second frequency (or set of frequencies). A UE may determine relevant timing and/or configuration for the second frequency (or set of frequencies) prior to transitioning from communications via the first frequency (or set of frequencies). Thus, the UE may efficiently begin communications at a second frequency (or set of frequencies) that are different than the first frequency (or set of frequencies)—for example, without performing a random access procedure.

Abstract: Certain aspects of the present disclosure provide techniques for time division multiplexing (TDMing) user equipment (UE) data using guard interval (GI)-based waveforms. An example method generally includes communicating with a device using a frame format, the frame format comprising a first symbol, a second symbol, and a third symbol, wherein: the first symbol comprises a first data portion for a first UE and a first GI corresponding to the first UE; the third symbol comprises a second data portion for a second UE and a second GI corresponding to the second UE, wherein the third symbol is later in time than the first symbol; and the second symbol comprises a gap or a reference signal (RS), a third GI corresponding to the first UE, and a fourth GI corresponding to the second UE, wherein the second symbol is between the first and third symbol in time.

Abstract: Methods, systems, and devices for wireless communications are described. A UE operating in an NTN may receive an indication of coverage information for a first cell associated with the NTN. The coverage information may indicate a coverage area supported by the first cell for wireless communications. The UE may transmit, based on location information of the UE and the coverage information, a message indicating a timing information associated with a measurement-based handover for the UE from the first cell to a second cell associated with the non-terrestrial network. For example, the message may include a recommendation for the UE to perform a non-measurement-based handover or an indication that the UE cannot complete the measurement-based handover before leaving the coverage area of the first cell.
