PUCCH resource management mechanism for coordinated multi-point operation

摘要

A method for uplink control signaling in CoMP operation is described. The method includes allocating a first set of CCEs for an associated transmission from an AP to an associated UE. The method also includes transmitting, to a RRH, a message including an indication of the first set of CCEs. The message including the indication of a first set of CCEs is received at the RRH. The method also includes allocating, by the RRH, a second set of CCEs for an associated transmission from the RIM to an associated UE. A UE receives the transmission of downlink control information beginning at a first CCE. The method includes receiving a PUCCH resource offset parameter, the PUCCH resource offset parameter indicating the reception point for the UE. The UE determines an uplink control channel resource based on the first CCE and the PUCCH resource offset parameter.

1. A method comprising:
receiving, at a remote radio head, a message comprising an indication of a first set of control channel elements for an associated transmission from an access point to a first associated user equipment; and allocating, at least in part in response to the receiving, a second set of control channel elements for an associated transmission from the remote radio head to a second associated user equipment, wherein the second set of control channel elements are different from the first set of control channel elements.
