Abstract
Management and distribution of PUCCH resources between first and second eNBs in a CoMP system is disclosed, in which the control and data transmission for a given UE is decoupled. The decoupling of the control and data transmissions allows the first eNB to transmit control information while the second eNB or remote radio head (RRH) transmits data. In such systems, the first eNB communicates a dynamic PUCCH parameter to UEs served in a decoupled manner. The dynamic PUCCH parameter allows the UE to determine uplink communications for the dynamic PUCCH region transmitted to the second eNB in such a position that will not overlap or cause interference with the dynamic PUCCH regions reserved by the first eNB.
Claims100
A method of wireless communication, comprising:
- receiving a first uplink parameter related to resource determination for transmission of an uplink control channel, wherein the first link parameter is a first starting index of the uplink control channel;
- receiving a second uplink parameter related to resource determination for transmission of the uplink control channel, wherein the second link parameter is a second starting index of the uplink control channel;
- receiving a data transmission from a first cell;
- determining a resource for transmission of the uplink control channel based at least in part on the second uplink parameter;
- and
- transmitting the uplink control channel using the determined resource.
