System and method for uplink and downlink in multi-point communications

A user equipment (UE), comprising:

• a non-transitory memory storage storing instructions;
• and
• one or more hardware processors in communication with the non-transitory memory storage, wherein the one or more hardware processors execute the instructions to cause the UE to perform operations comprising:
• receiving first configuration information of a bandwidth part (BWP) in a carrier for a serving cell, the first configuration information configuring a first signal or channel on the BWP in the carrier for the serving cell, wherein the first signal or channel is associated with a first synchronization signal block (SSB), and wherein the first configuration information indicates a first parameter associated with the first SSB;
• receiving second configuration information of the BWP in the carrier, the second configuration information configuring a second signal or channel on the BWP in the carrier, wherein the second signal or channel is associated with a second SSB different from the first SSB, and wherein the second configuration information indicates a second parameter associated with the second SSB;
• and
• performing first transmission or first reception of the first signal or channel in accordance with the first parameter associated with the first SSB and performing second transmission or second reception of the second signal or channel in accordance with the second parameter associated with the second SSB.

A method, comprising:

• transmitting, by a base station to a user equipment (UE), first configuration information of a bandwidth part (BWP) in a carrier for a serving cell, the first configuration information configuring a first signal or channel on the BWP in the carrier for the serving cell, wherein the first signal or channel is associated with a first synchronization signal block (SSB), and wherein the first configuration information indicates a first parameter associated with the first SSB;
• transmitting, by the base station to the UE, second configuration information of the BWP in the carrier, the second configuration information configuring a second signal or channel on the BWP in the carrier, wherein the second signal or channel is associated with a second SSB different from the first SSB, and the second configuration information indicates a second parameter associated with the second SSB;
• and
• performing, by the base station with a second base station, first transmission to the UE or first reception from the UE of the first signal or channel in accordance with the first parameter associated with the first SSB,
• wherein the second base station performs second transmission or second reception of the second signal or channel in accordance with the second parameter associated with the second SSB.

A base station, comprising:
