Provided are a communication mode switching method, and an apparatus and a device. The method includes sending a Packet Data Convergence Protocol (PDCP) data transmission status of user equipment in a first communication mode to a second network device, wherein the second network device is configured to use a second communication mode to deliver a service to the user equipment according to the PDCP data transmission status.

A method for determining a system operating mode and a terminal implementing the method are provided. The method includes: obtaining first information, where the first information is information detected or received by the terminal; and determining a system operating mode of the terminal in a first band based on the first information, where the system operating mode includes a licensed mode and an unlicensed mode.

Disclosed are a communication scheme and a system thereof for converging IoT technology and a 5G communication system for supporting a higher data transmission rate beyond that of a 4G system. The disclosure can be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars, connected cars, health care, digital education, retail business, security, and safety) based on the 5G communication technology and the IoT-related technology. Further, disclosed is a 5G or 6G communication system for supporting a higher data transmission rate than a post-4G communication system such as LTE.

In a wireless network, a user equipment (UE) may skip an uplink transmission associated with a dynamic uplink grant. In such cases, when the UE skips an uplink transmission that would have been concurrent with a downlink transmission, the UE may perform one or more mode-dependent control operations. For example, because the uplink transmission would result in a full-duplex operation if the UE were to perform the uplink transmission, the UE may reset a timer associated with switching from a full-duplex mode to a half-duplex mode and/or perform one or more mode-dependent control operations in the full-duplex mode. Alternatively, because the UE refrains from performing the uplink transmission that would have resulted in a full-duplex operation, the UE may maintain the timer associated with switching from the full-duplex mode to the half-duplex mode and/or perform the one or more mode-dependent control operations in the half-duplex mode.

The present disclosure provides a method and device in a node used for wireless communications. A node first receives a first signaling in a first time-frequency resource set, the first signaling is used to indicate a first reference signal resource; then receives a second signaling in a second time-frequency resource set; the first time-frequency resource set and the second time-frequency resource set are associated with a candidate resource set, the candidate resource set supports a DCI format scrambled by a first ID, and the second time-frequency resource set is located after the first time-frequency resource set; a demodulation reference signal of a channel occupied by the second signaling is quasi co-located with a target reference signal resource. The application improves the method and device for updating TCI state in the case of M-TRP supporting multicast, so as to optimize the system performance.

Methods, computer readable media, and apparatus for determining a receive (Rx) number of spatial streams (NSS) for different bandwidths (BWs) and modulation and control schemes (MCSs) are disclosed. An apparatus is disclosed comprising processing circuitry configured to decode a supported HE-MCS and a NSS set field, the supported HE-MSC and NSS set field received from an high-efficiency (HE) station. The processing circuitry may be further configured to determine a first maximum value of N receive (Rx) SS for a MCS and a bandwidth (BW), where the first maximum value of N Rx SS is equal to a largest number of Rx SS that supports the MCS for the BW as indicated by the supported HE-MCS and NSS set field; and, determine additional maximum values based on an operating mode (OM) notification frame, and a value of an OM control (OMC) field. Signaling for BW in 6 GHz is disclosed.

The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may measure a RSRP of a CRS for each of a plurality of neighboring cells. The apparatus may also calculate an interference strength of each of the plurality of neighboring cells based on the RSRP measurement of the CRS for each of the plurality of neighboring cells. Additionally, the apparatus may compare a PDSCH demodulation performance of the UE based on rate matching for a CRS offset associated with each of the plurality of neighboring cells with the PDSCH demodulation performance of the UE based on skipping the rate matching for the CRS offset. The apparatus may also transmit a request for the rate matching or skipping the rate matching for the CRS offset based on the comparison of the PDSCH demodulation performance of the UE.

A sidelink transmission control method, a transmit terminal, and a receive terminal are provided, where a method of a transmit terminal side includes: determining whether a trigger condition for resource reselection is satisfied; and performing a first operation in a case that the trigger condition for resource reselection is satisfied, where the first operation includes at least one of resource reselection, modulation and coding scheme MCS adjustment, and power adjustment.

A user equipment (UE) may simulate transmissions received from a BS to perform on-device testing of the UE. For example, the UE may be configured to loopback uplink data from the UL data path and input the uplink data as simulated downlink data for processing in the DL data path. The uplink data may include data related to a video call or network diagnostics. The user application data generated by the application and proceeding through the UL data path may be used to validate the DL data path. Downlink control information (DCI) may be determined by the UE and provided to the DL data path to accompany the uplink data. The DCI may include simulated uplink grants and/or simulated downlink scheduling assignments. The simulated downlink scheduling assignments may be determined based on availability of the uplink data in the UE's memory.

User Equipment (UE) determines a location of a resource of at least one control channel for transmission repetition, and the at least one control channel is located in a control region. The UE detects, according to the location of the resource, control signaling transmitted by a base station using the at least one control channel.
