Systems and methods are disclosed for enhanced transmit and receive performance for time synchronization. In one embodiment, a method performed by an access node for a wireless network comprises receiving a Physical Random Access Channel (PRACH) preamble from a User Equipment (UE) and deriving timing-related information based on the PRACH preamble in accordance with a defined uplink signal timing detection error requirement, the defined uplink signal timing detection error requirement being stricter than a respective uplink signal timing detection error requirement defined in Release 15 and 16 of Third Generation Partnership Project New Radio (NR) specifications for a subcarrier spacing used for the PRACH preamble. The method further comprises sending the timing-related information to the UE. In this manner, enhanced time synchronization performance can be achieved.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a first channel measurement resource (CMR) associated with a first transmission configuration indicator (TCI) state and a second CMR associated with a second TCI state. The UE may also receive an indication of a first interference measurement resource (IMR) associated with the first CMR and a second (IMR) associated with the second CMR. The UE may obtain an interference measurement using the first IMR, the second IMR, or both, for a channel state information (CSI) report for ajoint transmission hypothesis associated with the CMR and the second CMR. The UE may transmit the CSI report based at least in part on the interference measurement (s).

A method includes a first device that sends a spectrum sensing request frame to a second device, where the spectrum sensing request frame requests the second device to perform spectrum sensing. The second device sends a request acknowledgment frame which, is used to acknowledge that the spectrum sensing request frame is received. The second device performs spectrum sensing based on the at least one spectrum sensing parameter, to obtain a spectrum sensing result. The second device sends a spectrum sensing feedback frame to the first device, where the spectrum sensing feedback frame is used to feed back the spectrum sensing result. The first device sends the spectrum sensing request frame, so that the second device can perform spectrum sensing based on information carried in the spectrum sensing request frame, and the first device can obtain the accurate spectrum sensing result of the second device.

A sensing method and apparatus and a communication device. The sensing method in embodiments of this application includes: A first device receives, based on each received beam determined by a first beam sweeping mode, an echo signal of a first signal sent by a second device. In a case that it is determined based on a first echo signal received at a first moment that a sensing object is detected, the first device obtains a first received beam used at a second moment based on the first echo signal. The first device receives, at the second moment based on the first received beam, a second echo signal of a first signal sent by the first device. The second moment is a moment after the first moment.

Methods and systems for detecting and mitigating the effects of time of flight interference of a radio frequency (RF) signal are provided. A wireless communication network may determine, based on one or more parameters being sufficiently different than a baseline value, that time of flight interference is occurring based on the undesirable propagation of a first cell's downlink signals into a second cell's coverage area. In response to the determination, the network may identify an offending base station and modify the RF transmission characteristics of the offending base station to prevent or mitigate the impact of the interference event on the RF signal's propagation.

A network device includes receiver and a processor. The receiver receives a signal from a group of terminal devices, over a physical uplink control channel (PUCCH) Format 0 (FMT0). The processor is coupled to the receiver, performs processing on the received signal to detect payloads and obtain SNRs corresponding to the terminal devices in the group, and utilizes the detected payloads and the SNRs for handling further communications with the terminal devices. In the processing, the processor obtains a time domain sequence from the received signal by performing a transform from a frequency domain into a time domain, determines a plurality of correlation power values from the time domain sequence, extracts, from the plurality of correlation power values, a maximum correlation power value corresponding to each terminal device, and determines a current noise power value for SNR based on an instant noise power value, and a previous noise power value.

Methods, systems, and devices for wireless communication are described. Generally, the techniques described herein may enable joint reporting of channel state information (CSI) and cross-link interference (CLI). For example, a network entity may transmit, to a user equipment (UE), a joint configuration indicative of a first set of resources associated with generation of one or more CSI metrics and a second set of resources associated with generation of one or more CLI metrics. As such, the UE may generate the one or more CSI metrics and one or more CLI metrics in accordance with the joint configuration and transmit a joint report indicative of the one or more CSI metrics and the one or more CLI metrics.
