DOWNLINK CONTROL SIGNALING FOR COORDINATED MULTIPOINT TRANSMISSION
First Claim
1. A base station configured for use in a coordinated multipoint (CoMP) transmission system, the base station comprising:
- a processor configured to;
transmit a first and a second physical downlink control channel (PDCCH) to a user equipment (UE) in a subframe, wherein the first PDCCH has a first downlink control information (DCI) format and the second PDCCH has a second DCI format; and
transmit a first transport block of at least one CoMP transmission to the UE in the subframe according to the first PDCCH, the at least one CoMP transmission comprising the first transport block from the base station and a second transport block from a second base station, wherein the second transport block is scheduled according to the second PDCCH.

Abstract
A base station performs a method for coordinated multipoint (CoMP) transmission to a plurality of user equipments (UEs). The method includes transmitting a first and a second physical downlink control channel (PDCCH) to a user equipment (UE) in a subframe, wherein the first PDCCH has a first downlink control information (DCI) format and the second PDCCH has a second DCI format. The method also includes transmitting a first transport block of at least one CoMP transmission to the UE in the subframe according to the first PDCCH, the at least one CoMP transmission comprising the first transport block from the base station and a second transport block from a second base station, wherein the second transport block is scheduled according to the second PDCCH.
