System and method for transmitting uplink data associated with downlink multiple point transmission

摘要

A system and method for transmitting UL data associated with DL multiple point transmission are provided. A method for transmission point operations includes determining an identifier associated with each transmission point in a downlink serving set that includes a primary transmission point and at least one secondary transmission point, transmitting downlink information to a user equipment, and receiving, at a receiving transmission point, uplink data including a first identifier of an intended recipient from the user equipment, where the intended recipient is a first transmission point in the downlink serving set. The method also includes forwarding the uplink data to the intended recipient based on the first identifier.

1. A method for transmission point operations, the method comprising:
configuring an identifier associated with a bearer served by a multiple point system comprising a primary transmission point and at least one secondary transmission point, wherein an intended recipient of an uplink (UL) data of the bearer is determinable based on the identifier; transmitting downlink information of the bearer to a user equipment; receiving, at a receiving transmission point, the uplink data of the bearer from the user equipment including an identification information related to the identifier, determining, in accordance with the identifier, whether the intended recipient is located at the receiving transmission point or a first transmission point of the multiple point system; and forwarding, by the receiving transmission point, the uplink data to the first transmission point upon determining the intended recipient of the uplink data is a corresponding packet data convergence control (PDCP) entity of the uplink data located at the first transmission point of the multiple point system, wherein the PDCP entity is assigned to the user equipment and the bearer.
