Information transmission method, terminal device and network device
View Patent ↗The present disclosure relates to an information transmission method, a terminal device, and a network device. The method includes determining N uplink resources used to carry N sets of uplink feedback information. The N sets of uplink feedback information is used to feed back data transmission conditions in N sets of downlink resources. The i-th set of uplink feedback information corresponding to the i-th uplink resource is used to feed back the data transmission condition in the i-th set of downlink resources, when i is greater than 1. The i-th set of downlink resources include some or all of the (i−1)-th set of downlink resources, where N is a positive integer greater than 1, and i=1, 2, 3, . . . , N. The method also includes determining M available uplink resources in the N uplink resources, where M is a positive integer less than or equal to N. The method further includes using the M available uplink resources to send, to the network device, M sets of uplink feedback information corresponding to the M available uplink resources.
