Abstract

Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method of communication comprises receiving, at a first device, control information from a second device; determining a transmission control indication (TCI) codepoint from the control information, the TCI codepoint indicating at least a first TCI state and a second TCI state to be used for communicating data with the second device over a physical shared channel; in response to a number of repetitions of the data being configured to be scheduled by the control information, determining a first configuration for communicating the repetitions of the data with the second device, the first configuration assigning the first and second TCI states to the repetitions of the data; and communicating, at least based on the first configuration, the repetitions of the data with the second device over the physical shared channel.

Claims (67)

receiving control information comprising a redundancy version (RV) indication field associated with a plurality of physical downlink shared channel (PDSCH) transmission occasions for repetition, the plurality of PDSCH transmission occasions comprising at least one PDSCH transmission occasion associated with a first transmission control indication (TCI) state and at least one PDSCH transmission occasion associated with a second TCI state, the RV indication field corresponding to a first RV sequence and a second RV sequence, and the first RV sequence being applied to the at least one PDSCH transmission occasion associated with the first TCI state, the second RV sequence being applied to the at least one PDSCH transmission occasion associated with the second TCI state; and

receiving a PDSCH associated with the plurality of PDSCH transmission occasions based on the control information;

wherein,

in a case where the number of the plurality of PDSCH transmission occasions is 2,

the first RV sequence is {0}, the second RV sequence is {3}, in a case where a value of the RV indication field is 0, and

the first RV sequence is {2}, the second RV sequence is {1}, in a case where a value of the RV indication field is 2;

in a case where the number of the plurality of PDSCH transmission occasions is 4,

the first RV sequence is {0, 2}, the second RV sequence is {3, 1}, in a case where a value of the RV indication field is 0;

in a case where the number of the plurality of PDSCH transmission occasions is 8,

the first RV sequence is {a, b, c, d}, the second RV sequence is {((a+3) mod 4), ((b+3) mod 4), ((c+3) mod 4), ((d+3) mod 4)}, wherein each of a, b, c and d is from a set of {0, 2, 3, 1}, and values of a, b, c and d are different with each other.

2. The method of claim 1 , wherein

in a case where the number of the plurality of PDSCH transmission occasions is 2,

the at least one PDSCH transmission occasion associated with the first TCI state comprises a first PDSCH transmission occasion of the plurality of PDSCH occasions, and the at least one PDSCH transmission occasion associated with the second TCI state comprises a second PDSCH transmission occasion of the plurality of PDSCH occasions;

in a case where the number of the plurality of PDSCH transmission occasions is 4,

the at least one PDSCH transmission occasion associated with the first TCI state comprises first and second PDSCH transmission occasions of the plurality of PDSCH transmission occasions, and the at least one PDSCH transmission occasion associated with the second TCI state comprises third and fourth PDSCH transmission occasions of the plurality of PDSCH transmission occasions; or

the at least one PDSCH transmission occasion associated with the first TCI state comprises first and third PDSCH transmission occasions of the plurality of PDSCH transmission occasions, and the at least one PDSCH transmission occasion associated with the second TCI state comprises second and fourth PDSCH transmission occasions of the plurality of PDSCH transmission occasions.

3. A method, performed by a network device, comprising:

transmitting control information comprising a redundancy version (RV) indication field associated with a plurality of physical downlink shared channel (PDSCH) transmission occasions for repetition, the plurality of PDSCH transmission occasions comprising at least one PDSCH transmission occasion associated with a first transmission control indication (TCI) state and at least one PDSCH transmission occasion associated with a second TCI state, the RV indication field corresponding to a first RV sequence and a second RV sequence, and the first RV sequence being applied to the at least one PDSCH transmission occasion associated with the first TCI state, the second RV sequence being applied to the at least one PDSCH transmission occasion associated with the second TCI state; and

transmitting a PDSCH associated with the plurality of PDSCH transmission occasions based on the control information;

wherein,

in a case where the number of the plurality of PDSCH transmission occasions is 2,

the first RV sequence is {0}, the second RV sequence is {3}, in a case where a value of the RV indication field is 0, and

the first RV sequence is {2}, the second RV sequence is {1}, in a case where a value of the RV indication field is 2;

in a case where the number of the plurality of PDSCH transmission occasions is 4,

the first RV sequence is {0, 2}, the second RV sequence is {3, 1}, in a case where a value of the RV indication field is 0;

in a case where the number of the plurality of PDSCH transmission occasions is 8,

4. The method of claim 3 , wherein

in a case where the number of the plurality of PDSCH transmission occasions is 2,
