Method, device and computer storage medium for communication

A method of communication, performed by a terminal device, comprising:

• receiving, from a network device, at least one configuration of a first subset of transmission configuration indicator (TCI) states and a second subset of TCI states, wherein the first subset of TCI states is associated with a first identity, and the second subset of TCI states is associated with a second identity;
• receiving a downlink control information (DCI) with an indication of a codepoint corresponding to at least one of a first TCI state from the first subset of TCI states or a second TCI state from the second subset of TCI states;
• and
• receiving, after a timing, a first physical downlink control channel (PDCCH) with the first TCI state, in a case where the first PDCCH is in a control resource set (CORESET) from a first subset of CORESETs,
• receiving, after the timing, the first PDCCH with the second TCI state, in a case where the first PDCCH is in a CORESET from a second subset of CORESETs,
• wherein the timing is based on a threshold and a last symbol of a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) with a hybrid automatic repeat request (HARQ).
