Methods and apparatus for related to a transmission and reception point

A method performed by a transmission and reception point (TRP) in a wireless communication system, the method comprising:

• transmitting, to a terminal, a radio resource control (RRC) message configuring a plurality of transmission configuration indicator (TCI) states associated with a physical downlink shared channel (PDSCH) and a control resource set (CORESET) configuration for a bandwidth part (BWP) of a serving cell;
• transmitting, to the terminal, a medium access control (MAC) control element (CE) including information bits corresponding to the plurality of TCI states and 1 bit indicating that at least one activated TCI state among the plurality of TCI states is associated with a transmission and reception point (TRP) which is one of a first TRP or a second TRP, wherein one bit of the information bits indicates an activation state or a deactivation state of each TCI state among the plurality of TCI states, and wherein the first TRP and the second TRP are for the BWP of the serving cell;
• transmitting, to the terminal, downlink control information (DCI) scheduling a PDSCH, the DCI including TCI information indicating a TCI state for the PDSCH from the at least one activated TCI state for the TRP;
• and
• transmitting, to the terminal, the PDSCH scheduled by the DCI based on the TCI state indicated by the TCI information,
• wherein the TRP is identified by a value of the 1 bit from the first TRP or the second TRP, based on the CORESET configuration for the BWP of the serving cell, the CORESET configuration being configured with an index for the CORESET.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a processor configured to:
• receive a radio resource control (RRC) message configuring a plurality of transmission configuration indicator (TCI) states associated with a physical downlink shared channel (PDSCH) and a control resource set (CORESET) configuration for a bandwidth part (BWP) of a serving cell,
• receive a medium access control (MAC) control element (CE) including information bits corresponding to the plurality of TCI states and 1 bit indicating that at least one activated TCI state among the plurality of TCI states is associated with a transmission and reception point (TRP) which is one of a first TRP or a second TRP, wherein one bit of the information bits indicates an activation state or a deactivation state of each TCI state among the plurality of TCI states, and wherein the first TRP and the second TRP are for the BWP of the serving cell,
• receive, from the TRP, downlink control information (DCI) scheduling a PDSCH, the DCI including TCI information indicating a TCI state for the PDSCH from the at least one activated TCI state for the TRP, and
• receive, from the TRP, the PDSCH scheduled by the DCI based on the TCI state indicated by the TCI information,
• wherein the TRP is identified by a value of the 1 bit from the first TRP or the second TRP, based on the CORESET configuration for the BWP of the serving cell, the CORESET configuration being configured with an index for the CORESET.
