Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.

Abstract: Embodiments of the present disclosure relate to methods, a terminal device, a network device, and computer program products for SCell management in wireless communication. A terminal device receives from a network device configuration information for configuring a triggering mode. The triggering mode is for triggering activation of a secondary cell of the terminal device and a transmission of a temporary reference signal in the secondary cell. Based on the configured triggering mode, the terminal device receives first triggering information on the activation of the secondary cell and second triggering information on the transmission of the temporary reference signal for performing the activation of the secondary cell. In this way, it is possible to reduce the latency of activation/de-activation procedure for SCG and secondary cells.

Abstract: Described are processing time approaches to simultaneous multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In various approaches, simultaneously scheduling a plurality of physical downlink shared channels (PDSCHs) through a single DCI transmitted via a physical downlink control channel (PDCCH) occurs, wherein each of the plurality of PDSCHs is associated with a respective cell in a plurality of cells. The approaches further include transmitting data to or receiving data to a user equipment (UE) based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH. In other aspects, a hybrid automatic repeat request-acknowledgement (HARQ-ACK) is received via a physical uplink control channel (PUCCH), the HARQ-ACK having been sent by a user equipment (UE) in response to one of the plurality of PDSCHs, wherein the HARQ-ACK is sent no earlier than a time offset following a reference time in one of the plurality of PDSCHs. In other aspects, transmitting data to or receiving data to a user equipment (UE) is based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH, the time offset being configured to permit analog beam switching by a user equipment (UE).

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for reducing interferences for Sounding Reference Signal (SRS) by, for example, one or more of frequency domain interference randomization, code domain interference randomization, or power control. For example, a user equipment (UE) can be configured to determine a comb offset and/or a cyclic shift for each Sounding Reference Signal (SRS) transmission occasion for the UE. The comb offset and/or the cyclic shift change between different SRS transmission occasions of the UE. The UE is further configured to transmit an SRS to the base station using the determined comb offset and/or the determined cyclic shift during the SRS transmission occasion corresponding.

Abstract: A method that determines a resource at a first user equipment (UE) for a sidelink communication from the second UE to a first UE is described. In an exemplary embodiment, the method receives a request from the second UE to send data to the first UE. In addition, the method determines a preconfigured resource selection window that is used by the second UE. Furthermore, the method determines a first sensing result at the first UE. The determined first sensing result includes information to be reported to the second UE for a resource selection. The determined first sensing results has a plurality of first sensing types. Further, the method transmits the first sensing result from the first UE to the second UE.

Abstract: Techniques for changing a Transmission Configuration Indication (TCI) state by a user equipment (UE) operating in a wireless communications system are provided. The UE receives a first message including a TCI state change command from a network and determines, based on the first message, whether a time offset/frequency offset (TO/FO) and a reception (Rx) beam for a new TCI state are known by the UE. Based on the determination, the UE calculates a time delay of the UE to be prepared to receive a reference signal with the new TCI state, generates a second message indicating the time delay of the UE for the new TCI state, and transmits the second message to the network.

Abstract: A communication system provides reliable wideband communications with reduced power consumption in a user equipment (UE) receiver. A UE may include receiver circuitry to receive a radio frequency (RF) signal from a wireless network and output an analog baseband signal. The RF signal includes M copies of a duplicated signal in a frequency domain. The analog baseband signal includes the M copies of the duplicated signal uniformly offset from one another in the frequency domain by a bandwidth F and including a gap between adjacent copies. The UE further includes an anti-aliasing analog filter an analog to digital converter (ADC). The ADC samples an output of the anti-aliasing analog filter at a sampling frequency selected to obtain a digital baseband signal comprising a combined digital copy of the M copies of the duplicated signal folded over each other.
