摘要： A method includes receiving a first assignment for a first transmission with a first hybrid automatic repeat request (HARQ) process identifier (process ID) in a first network resource, receiving a second assignment for a second transmission with a second HARQ process ID in a second network resource, wherein the first network resource and the second network resource differ in a domain other than a time domain, detecting an indication indicating that the first HARQ process ID and the second HARQ process ID map to a same transmission block (TB), and communicating with an access node, a transmission associated with at least one of the first HARQ process ID or the second HARQ process ID.

摘要： This application provides a downlink control information transmission method and an apparatus. The method includes: receiving first downlink control information DCI in search space of a first carrier bandwidth part BWP, where if a frequency domain resource allocation type of the first BWP is a type 0, an L f -bit frequency domain resource allocation indication in the first DCI is an L f -bit bitmap, and bits in the L f - bit bitmap in descending order are respectively corresponding to resource block groups RBG 0 to RBG ( L f -1) in a second BWP; and for one bit in the L f -bit bitmap, when a value of the bit is 11, an allocated resource includes one RBG corresponding to the bit. According to this method, BWP switching or cross-BWP scheduling can be performed by using a truncated information field.

摘要： A method and an apparatus for switching a cell state are provided, and relate to the field of communication technologies. The method includes: A terminal device receives a first instruction from a network device, and switches a serving cell state based on the first instruction. The first instruction indicates to switch the serving cell state of the terminal device to or from a first state. When the serving cell state is the first state, a downlink carrier of a serving cell supports downlink communication, and an uplink carrier of the serving cell does not support uplink communication. Such a technical solution helps reduce a latency of serving cell state switching and improve communication performance.

摘要： This application provides an extended reality data transmission method and an apparatus. The method includes: determining that a data type is extended reality data; determining, based on the data type, to obtain, based on delay information and transmission error information, extended reality quality indicator XQI information corresponding to a target rate, where the XQI information indicates transmission quality of the extended reality data; and performing communication based on the XQI information. Because the XQI information can represent transmission quality of the extended reality XR data in a network, objective impact on the XR data in network transmission can be systematically evaluated by using the method, to guide a network operator to maintain and optimize the network based on a requirement of the XR data.

摘要： Embodiments of this application disclose a wireless communication method and an apparatus, to improve robustness of data transmission between a terminal device and a node device. The method in the embodiments of this application includes: A terminal device incorrectly receives first data in a first cell, where the first cell is a first primary cell. The terminal device sends first indication information in a second cell, where the second cell is a secondary cell or a second primary cell, and the first indication information is used to indicate that the first data is incorrectly received in the first cell, or is used to request transmission of the first data in the second cell. The terminal device receives the first data in the second cell. Therefore, in the embodiments of this application, the terminal device triggers, by using the indication information, sending of the data in the second cell to the terminal device. This improves the robustness of the data transmission.
