A terminal includes a controller configured to identify a resource that is included in a time domain in which a first channel used for transmitting a response related to retransmission control is allocated, and that is included in a frequency domain that is not used for transmitting the first channel; and a transmitter configured to transmit a second channel or a signal by using the resource.

A method and apparatus for switching between unicast and multicast by considering degraded user experience in a wireless communication system is described. A CU of a RAN node receives, from the DU, a first switching message including status of the MBS for each of the first wireless device and the second wireless device. A CU of a RAN node determines to switch the first transmission to a third transmission only for the first wireless device for the MBS, based on the received status of the MBS.

A communication method includes a first terminal device that determines first configuration information of first discontinuous reception DRX, where the first DRX controls the first terminal device to receive data on a sidelink. The first terminal device sends the first configuration information to a second terminal device, where the second terminal device is a terminal device that establishes a sidelink connection to the first terminal device. This can reduce power consumption of the terminal device.

The present application provides a method and a device in a node used for wireless communications. A first node receives first configuration information and second configuration information; transmits a first message, the first message comprising at least a former one of a first signature sequence and first data; and receives a second message; and transmits a third message on a second time-frequency resource block, a first bit block being used to generate the third message; the first configuration information indicates a first time-frequency resource block, the first time-frequency resource block being used to transmit the first signature sequence in the first message; the second configuration information indicates multiple shared resource units; whether the first signature sequence is mapped to one shared resource unit of the multiple shared resource units is used to determine whether the first message comprises the first data.

This application provides a communication method and apparatus. One example method includes, obtaining, by a terminal device, a first frequency domain resource and a second frequency domain resource, wherein the first frequency domain resource and the second frequency domain resource are independently configured, and the second frequency domain resource comprises a control-resource set (CORESET) 0 and an initial bandwidth part (BWP); and receiving, by the terminal device, first information, wherein the first information is used to schedule a downlink data channel, the first information comprises frequency domain resource assignment information, wherein the frequency domain resource assignment information indicates a frequency domain resource of the downlink data channel within a range of the first frequency domain resource, and the first information is scrambled by using a group-radio network temporary identifier (G-RNTI) this application.

A protocol layer on top of the Bluetooth low energy (BLE) system of paired devices to provide transmission that allows arbitrary sizes of data to be sent. To guarantee transmissions, the transmissions may be validated and, if required, resent to replace data that was lost or corrupted. The protocol layer also supports Remote Procedure Calls to allow functions on either of two connected devices to be executed on one device on behalf of the other. A further protocol layer also allows high priority, short messages to temporarily interrupt the transmission of low priority, long messages.

Embodiments herein relate to a method performed by a radio network node for handling transmission of data from a wireless device in a wireless communication network. The radio network node determines a delay value for a transmission of data from the wireless device based on a transmission type of data from the wireless device or a capability of the wireless device. The capability is related to a processing time for processing received data from the radio network node, or for processing data for transmission to the radio network node. The radio network node further transmits an indication, to the wireless device, which indication indicates the determined delay value.
