20110038328 | METHOD AND APPARATUS THAT FACILITATES INTERFERENCE CANCELLATION FOR CONTROL CHANNELS IN HETEROGENOUS NETWORKS - Aspects are described for reducing interference in wireless systems. In a first embodiment, an uplink acknowledgment region associated with a macro cell is determined, and an assignment of uplink control resources is restricted to a region within the uplink acknowledgment region. A control signal is then transmitted to user equipment via the assignment of uplink control resources. In another embodiment, control signals are received from wireless terminals, which include desired uplink control signals associated with an access point base station, as well as interfering uplink acknowledgement signals associated with macro cells. The control signals may then be regenerated by cancelling the set of interfering signals from the control signals. The desired uplink control signals are then decoded. | 2011-02-17 |
20110038329 | EFFICIENT CONTROL CHANNEL DECODING IN CoMP COMMUNICATIONS - Certain embodiments of the present disclosure propose two efficient designs for a control channel in a Coordinated Multi-Point (CoMP) system. The proposed designs enable a user equipment (UE) to transmit acknowledgement (ACK) and negative acknowledgement (NACK) signals to one or more access points (APs) upon receiving transmissions from them. | 2011-02-17 |
20110038330 | ROBUST DECODING OF CoMP TRANSMISSIONS - Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations. | 2011-02-17 |
