Abstract
A data transmission method includes steps of: acquiring, by a network side, a current data transmission rule, the current data transmission rule including a mapping relationship between currently-scheduled K UEs and data layers on N transmission resources corresponding to a selected encoding matrix, one UE at least occupying one data layer; and transmitting, by the network side, data to the K UEs in accordance with the current data transmission rule.
Claims24
A data transmission method, comprising steps of:
- acquiring, by a network side, a mapping relationship between currently-scheduled K User Equipments (UEs) and data layers on at least log2(K+1) transmission resources corresponding to a selected encoding matrix, where one UE at least occupying one data layer;
- and
- transmitting, by the network side, data to the K UEs in accordance with the mapping relationship between the currently-scheduled K UEs and the data layers on the at least log2(K+1) transmission resources corresponding to the selected encoding matrix.
8-21. (canceled)
A data reception method, comprising steps of:
- acquiring, by a User Equipment (UE), a mapping relationship between currently-scheduled K UEs and data layers on at least log2(K+1) transmission resources corresponding to a selected encoding matrix, where one UE at least occupying one data layer;
- and
- receiving, by the UE, feedback data from a network side, the feedback data being fed back by the network side after receiving data transmitted from the UE in accordance with the mapping relationship between the currently-scheduled K UEs and the data layers on the at least log2(K+1) transmission resources corresponding to the selected encoding matrix.
A network side device, comprising:
- a processing unit configured to acquire a mapping relationship between currently-scheduled K User Equipments (UEs) and data layers on at least log2(K+1) transmission resources corresponding to a selected encoding matrix, where one UE at least occupying one data layer;
- and
- a transmission unit configured to transmit data to the K UEs in accordance with the mapping relationship between the currently-scheduled K UEs and the data layers on the at least log2(K+1) transmission resources corresponding to the selected encoding matrix.
30-49. (canceled)
A User Equipment (UE), comprising:
- a processing unit configured to acquire a mapping relationship between currently-scheduled K UEs and data layers on at least log2(K+1) transmission resources corresponding to a selected encoding matrix, where one UE at least occupying one data layer;
- and
- a reception unit configured to receive feedback data from a network side, the feedback data being fed back by the network side after receiving data transmitted from the UE in accordance with the mapping relationship between the currently-scheduled K UEs and the data layers on the at least log2(K+1) transmission resources corresponding to the selected encoding matrix.
