Abstract
A method for downlink data transmission and related products are provided. The method includes: a terminal receives downlink control information (DCI) for scheduling multiple physical downlink shared channels (PDSCHs), wherein the DCI contains transmission configuration indicator (TCI) state indication; and the terminal determines a TCI state which is applied to each of the multiple PDSCHs according to at least one TCI state indicated by the TCI state indication.
Claims20
A method for downlink data transmission, comprising:
- receiving, by a terminal, DCI for scheduling multiple PDSCHs, wherein the DCI contains a TCI state indication;
- and
- determining, by the terminal, a TCI state which is applied to each of the multiple PDSCHs according to at least one TCI state indicated by the TCI state indication;
- wherein the multiple PDSCHs are N PDSCHs, the at least one TCI state is K TCI states and K equals to 2;
- and the K TCI states are applied to the N PDSCHs in circular or in sequence;
- under the condition that the multiple PDSCHs are applied to the at least one TCI state in circular:
- when N=K=2, an index sequence of the TCI states corresponding to the two PDSCHs is {0, 1};
- and
- when N>K=2, the n-th PDSCH in the multiple PDSCHs corresponds to the k-th TCI state in the at least one TCI state, and k=[(n−1) mod K+1].

A terminal, comprising:
- a processor;
- a transceiver;
- and
- a memory storing one or more programs which, when executed by the processor, are operable with the transceiver to receive DCI for scheduling multiple PDSCHs, wherein the DCI contains TCI state indication, and operable with the processor to determine a TCI state which is applied to each of the multiple PDSCHs according to at least one TCI state indicated by the TCI state indication;
- wherein the multiple PDSCHs are N PDSCHs, the at least one TCI state is K TCI states and K equals to 2;
- and the K TCI states are applied to the N PDSCHs in circular or in sequence;
- under the condition that the multiple PDSCHs are applied to the at least one TCI state in circular:
- when N=K=2, an index sequence of the TCI states corresponding to the two PDSCHs is {0, 1};
- and
- when N>K=2, the n-th PDSCH in the multiple PDSCHs corresponds to the k-th TCI state in the at least one TCI state, and k=[(n−1) mod K+1].
