A system and a method are disclosed for a terminal in a wireless communication system. The method includes monitoring for at least one of a first condition or a second condition, wherein the first condition includes a CSI-RS or a PDSCH overlapping with an uplink subband in a subband full-duplex operation and becoming non-contiguous in a frequency domain, and wherein the second condition includes different network antenna patterns or power patterns being used in a network energy saving operation for transmission of the CSI-RS; and relaxing processing requirements related to at least one of a processing timeline or occupied computational resources, in response to the first condition or the second condition occurring.

Even when the lengths of data items to be transmitted to users are not the same, the frames multiplexed at the same time finally have the same frame length and are transmitted. Even when the lengths of frames for the users are not the same at the time when a transmission request is received from a higher layer, a communication apparatus reconfigures at least two of the frames having short lengths into a frame having a long length through Aggregation so that the frames finally have the same frame length and transmits the frames at the same time in a multiplexed manner. On the transmitter side, the transmission power used per destination communication station can be increased due to a decrease in the total number of multiplexed frames. On the receiver side, an unstable AGC operation can be prevented.

Channel feedback for non-orthogonal multiple access (NOMA) multiple-input multiple-output (MIMO) communication systems may be reported by determining a measurement set of transmission strategies for channel feedback for a non-orthogonal channel. Estimates of channel quality for downlink transmissions to the UE corresponding to respective transmission strategies of the measurement set may then be determined. A channel feedback report may then be sent. The channel feedback report may include indicators of channel quality for a subset of the measurement set of transmission strategies.

A method for a User Equipment (UE) operating in a wireless communication system including a Primary Cell (PCell) and a first Secondary Cell (SCell) with a Physical Uplink Control Channel (PUCCH) resource. The method includes receiving a parameter included in information about a second SCell without the PUCCH resource. The parameter indicates that a Hybrid Automatic Repeat Request (HARQ) feedback of the second SCell is to be sent on the first SCell. The method further includes transmitting the HARQ feedback of the second SCell to the first SCell.

A signal structure for use in D2D communications is described. In one embodiment, a preamble for automatic gain control at the receiver end is included in the transmitted signal. Techniques for scheduling of D2D transmissions using carrier sensing multiple access (CSMA) and a power control schemes for interference management are also described.

The apparatus may also transmits data for a second UE on an enhancement layer. The second UE is configured for NOMA communication. Additionally, the base layer is overlayed with the enhancement layer. The reference signal may include a cell specific reference signal. The apparatus may be further configured to receive a traffic power ratio for the second UE to be followed by the second UE when the second UE is a base layer UE in a NOMA communication.

Methods, systems, and devices for wireless communications are described. A scheduled entity transmits an indication of frequency resources that have different transmission requirements from those of other frequency resources in a smallest frequency domain scheduling unit that comprises the frequency resources for the scheduled entity. The scheduled entity receives, from a scheduling entity, signaling indicating at least one characteristic of how a channel is to be scheduled on the frequency resources from a scheduling entity. The scheduled entity communicates with the scheduling entity in accordance with the at least one characteristic.

The present application provides an information acquisition method and apparatus, a device, and a storage medium. The method includes: a network device sends a first signal to a terminal device. The first signal is different from those of a second signal sent by the network device to the terminal device in respect of at least one of a modulation mode, an encoding mode, a multi-access mode, or a waveform, and the first signal carries at least one type of information.

Various embodiments disclosed herein provide for facilitating updating a slot format used for establishing a radio sidelink. According an embodiment, a system can receive a slot format over a sidelink, wherein the slot format comprises a first release parameter and a transmit period. The system can further facilitate determining whether the first release parameter matches a second release parameter stored in the memory. The system can further facilitate, in response to the determining indicating that the first release parameter matched the second release parameter, updating a resource map used to transmit data, resulting in an updated resource map. The system can further facilitate transmitting the slot format based on the transmit period.
