Abstract: Example data transmission methods and apparatus are described. One example method includes receiving a slot format and physical uplink shared channel (PUSCH) parameters from a network device. First information is determined based on the slot format and the PUSCH parameters, wherein the first information is N slots, and N is an integer greater than 1. Whether to send data carried on a PUSCH in the N slots is determined based on slot formats of the N slots, wherein the data sent in the N slots is obtained by performing channel coding on a transport block (TB), and a TB size is determined based on available symbols in the N slots.

The method includes: generating, by a network device, first indication information, and sending the first indication information to a terminal device; and after receiving the first indication information, determining, by the terminal device, slot formats of M CCs based on the first indication information. The first indication information indicates K slot formats. The K slot formats are the slot formats of the M CCs configured for the terminal device. At least one slot format in the K slot formats is corresponding to at least two CCs in the M CCs. Configuration parameters of the at least two CCs have at least one type of same parameter. The configuration parameter includes at least one of the following parameters: a subcarrier spacing, a cyclic prefix, a bandwidth, or a frequency band.

Abstract: Embodiments of this application provide a resource configuration method and a device. According to this method, a first terminal device may reserve N resources based on listen before talk LBT durations corresponding to N transmission requirements. Because the LBT durations are considered, cases in which an LBT duration of a transmission requirement has not ended when a resource corresponding to the transmission requirement arrives can be reduced, so that a probability that the first terminal device can transmit data on the resource corresponding to the transmission requirement can be increased, thereby ensuring communication efficiency of the terminal device.

Abstract: In a packet processing method, a first device receives a first packet. The first packet includes a first bearing area and a second bearing area, and the first bearing area bears a first DA and a first SA. The first device performs slicing processing on the second bearing area to obtain N slices. The first device encapsulates each of the N slices to obtain N Ethernet frames. The first DA and the first SA are used for encapsulating at least one of the N slices. The first device sends the N Ethernet frames. In this way, when a physical link aggregation group performs network packet transmission, encapsulation overheads can be reduced, and network packet transmission efficiency can be improved.

Abstract: A method for determining a physical sidelink feedback channel resource and an apparatus are provided. The method includes: a first terminal device sends multicast information to at least two second terminal devices. The first terminal device determines, based on a total quantity of terminal devices in a multicast group and a resource group of physical sidelink feedback channel resources, a physical sidelink feedback channel resource corresponding to each second terminal device. The first terminal device receives, based on the physical sidelink feedback channel resource corresponding to each second terminal device, feedback information sent by each of the at least two second terminal devices. According to the foregoing method, physical sidelink feedback channel resources can be allocated to the terminal devices in the multicast group.

Abstract: A data transmission method and system are provided. The data transmission method includes: transmitting, by a BBU, frequency domain data obtained by performing a multi-antenna MIMO coding, to a RRU via a CPRI; receiving, by the RRU, the frequency domain data transmitted by the BBU, via the CPRI; and performing, by the RRU, an OFDM symbol generation processing on the frequency domain data received via the CPRI, to convert the frequency domain data into time domain data. With this method, a rate of the CPRI can be significantly lowered, and a bandwidth of the CPRI can be dynamically adjusted in the communication system according to the load and the usage of frequency resources, thereby lowering the bandwidth of the CPRI.
