Abstract: Provided are a wireless communication method, a terminal device and a network device. In the wireless communication method, the terminal device determines a target downlink channel for receiving a downlink signal, and/or the terminal device determines a target uplink channel for transmitting a back scattering signal. Correspondingly, the network device determines a target downlink channel for transmitting a downlink signal and/or the network device determines a target uplink channel for receiving a back scattering signal.

Abstract: A wireless communication method, a terminal device and a communication device. In the method the type or terminal group to which a terminal device belongs is determined. A backscatter signal is sent or a downlink signal is monitored on the basis of a configuration resource corresponding to the type or terminal group to which the terminal device belongs. On the basis of the configuration resource corresponding to the type or terminal group to which the terminal device belongs, the backscatter signal is sent or the downlink signal is monitored, that is, the terminal devices of different types or different groups correspond to different configuration resources.

Abstract: A wireless communication method includes: a type or terminal group to which a terminal device belongs is determined; and a backscatter signal is sent based on a transmission resource, a backoff parameter or a time unit corresponding to the type or terminal group to which the terminal device belongs.

Abstract: Provided are a wireless communication method, a first device, and a second device. The method includes that: a first device determines the number of repetitions of a first physical channel; counts a plurality of available time domain units corresponding to the first physical channel to obtain a count for each of the plurality of available time domain units; and performs sending of repeated data of the first physical channel based on the number of repetitions and the count for the each available time domain unit.

Abstract: The present invention relates to the field of tumor grade detection. Specifically disclosed are a gene combination for human tumor grading, and a use thereof. The gene combination for human tumor grading consists of a gene set A and a gene fragment set B. The gene combination for human tumor grading is obtained from high-throughput sequencing data of an actual renal cancer case of the Peking University First Hospital by means of specific pairing and clustering, is derived from real data, and can be used for malignancy degree grading and prognosis prediction for renal cancer and pan-cancer.
