摘要： A method for wireless communication, a terminal device, and a network device are provided in embodiments of the disclosure, so that in the case of many terminal devices that need to be identified at the same time and in the case of limited wireless resources available for multiplexing, the number of terminal devices involved in multiplexing can be limited through registration and/or deregistration, and thus a problem of congestion due to that a large number of terminal devices simultaneously make a response through backscattering can be solved. The method for wireless communication includes the following. A terminal device receives a first signal. The first signal is used to trigger the terminal device to perform registration, or the first signal is used to trigger the terminal device to perform deregistration; and the terminal device obtains, by means of power harvesting, power for communication and information gathering and processing.

摘要： Embodiments of the present application provide a wireless communication method, a terminal device, and a network device. The method comprises: sending first indication information, wherein the first indication information is used to indicate first parameters, and the first parameters are used to represent a first energy collection efficiency and/or first time interval of a terminal device. By means of the indicated first parameters, the network device may be enabled to know the energy collection efficiency or time interval of the terminal device. Thus, when the network device performs downlink transmission or uplink scheduling, communication parameters may be determined according to the energy collection efficiency or time interval indicated by a zero-power device, which reduces invalid transmission or scheduling, conserves transmission resources, reduces delay, and improves the system performance of zero-power communication.

摘要： Embodiments of the present application provide a wireless communication method, a terminal device, and a communication device. The method comprises: determining a type or terminal group to which a terminal device belongs; sending a backscattered signal on the basis of a transmission resource, fallback parameter, or time unit corresponding to the type or terminal group to which the terminal device belongs. In the present application, different transmission resources, fallback parameters, or time units are designed for terminal devices of different types or different groups, such that resource conflicts between the terminal devices of different types or different groups can be avoided, and the reliability of data transmission is improved. In particular, for an energy-constrained terminal device such as a terminal device that requires energy collection and storage between communications and is far away from a network device, the energy collected or stored by the terminal device can be saved and the energy utilization efficiency is improved, such that energy requirements during communication can be met.

摘要： Provided in the embodiments of the present application are a wireless communication method, a terminal device and a network device. The method comprises: acquiring a first bit sequence of a target transport block that has been encoded, wherein the target transport block is transmitted on the basis of a plurality of time domain unit sets; inputting the first bit sequence into a circular buffer region; reading a plurality of second bit sequences from the circular buffer region on the basis of at least one redundancy version (RV) and at least one position offset factor, wherein the at least one RV corresponds to at least one of the plurality of time domain unit sets, and the plurality of time domain unit sets or the at least one RV corresponds to the at least one position offset factor, and respectively sending the plurality of second bit sequences via the plurality of time domain unit sets. By means of the method provided in the present application, not only can the rate matching of a transport block in TBoMS be realized, but the loss of system bits corresponding to RV0 and/or RVI can also be prevented, thereby improving the decoding performance of a sequence that has been subjected to rate matching.
