Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a keep alive signal (KAS) that is associated with an initial timing synchronization between the UE and a network node. The UE may receive a minimum system information (MSI) message, from the network node and based at least in part on receiving the KAS, that includes synchronization signal block (SSB) information, initial access information, and scheduling information. Numerous other aspects are described.

Abstract: Aspects relate to configuration of a combined reference signal configuration including two or more reference signal configurations. Each reference signal configuration may be associated with one or more beam identifiers (IDs) is a respective communication direction. In some examples, the communication direction may be a downlink communication direction, an uplink communication direction, or a sidelink communication direction. Based on the combined reference signal configuration, reference signals associated with the two or more reference signal configurations may be communicated between devices (e.g., between a user equipment (UE) and a network entity or between two UEs). In addition, a UE may transmit a measurement report based on one or more report settings configured for the combined reference signal configuration.

Abstract: Methods, systems, and devices for wireless communications are described that support blind decoding limit adjustment techniques. A base station may configure a user equipment (UE) with one or more conditions that may trigger an adjustment to a number of blind decoding candidates that are to be monitored at the UE for a control information communication from the base station. A nominal number of blind decoding candidates may be configured at the UE, and the adjustment to the number of blind decoding candidates may reduce the number of blind decoding candidates from the nominal number, thus allowing the UE to perform blind decoding using less processing power, less time, or both. The trigger conditions may include one or more configured conditions that may support reliable communications with fewer blind decoding candidates.

Abstract: Aspects described herein relate to multiplexing, in frequency and to generate a multiplexed set of data subcarriers, a first set of data subcarriers for a first user or a first channel with a second set of data subcarriers for a second user or a second channel, adding at least one set of redundant subcarriers to the multiplexed set of data subcarriers to be transmitted in a unique-word orthogonal frequency division multiplexing (UW-OFDM) waveform to produce at least one of head samples or tail samples for the UW-OFDM waveform, mapping the multiplexed set of data subcarriers and the at least one set of redundant subcarriers as input to an inverse fast Fourier transform (IFFT), and generating the UW-OFDM waveform based on an output of the IFFT.

Abstract: A wireless device (e.g., a UE or a base station) may generate a hybrid symbol including a CP portion, a data portion, and at least one of a header portion or a tail portion. The CP portion may be located at a beginning of the hybrid symbol, and may include one or more CP samples that correspond to a predefined number of samples at an end of the hybrid symbol. The data portion may be located after the header portion or before the tail portion. The header portion may be located after the CP portion, and may include one or more predefined header samples. The tail portion may be located at the end of the hybrid symbol, and may include one or more predefined tail samples. The wireless device may generate a waveform including the generated hybrid symbol. The wireless device may transmit a signal based on the generated waveform.

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: Method and apparatus to updated PUCCH parameters in response to channel conditions. The apparatus transmits, to a UE, a configuration to update one or more PUCCH parameters. The apparatus identifies a change of channel conditions between the UE and the base station. The apparatus transmits, to the UE, an indication to update the one or more PUCCH parameters based at least on the change of the channel conditions. The apparatus communicates, with the UE, based on a PUCCH having the one or more PUCCH parameters updated.

Abstract: Method and apparatus to use different GI sequences for different FDM UEs. The apparatus calculates a GI of each UE from a set of UEs based at least on a delay spread associated with each UE from the set of UEs. The apparatus multiplexes data and the GI of each respective UE from the set of UEs to generate a waveform. The apparatus transmits the waveform to the set of UEs. The apparatus may receive, from each UE from the set of UEs, the delay spread associated with each UE from the set of UEs. The apparatus may multiplex the GI of each respective UE from the set of UEs prior to performing a DFT operation on the GI and the data. The apparatus may multiplex the GI of each respective UE from the set of UEs after performing an IDFT operation to generate the waveform.

Abstract: A method for wireless communication at a user equipment (UE) includes receiving, from a base station, a slot parameter that configures the UE to receive a number of symbols within a self-contained slot. The method also includes receiving, from the base station, a cyclic prefix (CP) parameter associated with a single symbol of the number of symbols, the CP parameter indicating a source of samples for a CP included at a beginning of the single symbol. The method further includes receiving, from the base station, the number of symbols within the self-contained slot. In some examples, a guard interval (GI) may be included at one or both of an end or a beginning of each symbol of the number of symbols. The CP may be outside a single FFT window of a number of FFT windows, associated with the single symbol of the number of symbols.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a physical uplink shared channel (PUSCH) message associated with a random access channel (RACH) procedure to a non-terrestrial network node. The UE may monitor a physical downlink control channel (PDCCH) for a contention resolution message associated with the RACH procedure during a contention resolution window. In some aspects, the UE may start to monitor the PDCCH a variable time period after the PUSCH message is transmitted. Numerous other aspects are provided.
