Methods and apparatuses for indicating an interference distribution in frame between base stations are provided. The method comprises: in response to a mismatch between a first frame allocation used by a first base station and a second frame allocation used by a second base station, transmitting, from the first base station to the second base station, a message for indicating an interference distribution in frame, A new information element, i.e., UL ABS (uplink Almost Blank Subframe) is introduced to indicate the uplink ABS information of the interfering base station. A modified DL ABS with a flag is used to indicate the downlink ABS information of the interfering base station, wherein the flag is to indicate that the DL ABS is used to protect UL transmission in the recipient base station.

Embodiments of the claimed subject matter provide a method and apparatus for transmitting an uplink overload indicator in a wireless communication system that operates according to time division duplexing. One embodiment of the method includes transmitting, from a first base station to a second base station, a message indicating that the first base station detected interference in at least one subframe of a time division duplex (TDD) frame allocated for reception of uplink signals at the first base station. A portion of the interference is generated by downlink transmissions from the second base station in the subframe of the TDD frame.

The present application describes embodiments of a method for coordinating cells in a cluster. One embodiment of the method includes sending, from a first base station, information identifying a first time division duplex (TDD) subframe configuration associated with the first base station. This embodiment of the method also includes receiving, at the first base station, an acknowledgment indicating that a second base station received the information. This embodiment of the method further includes sending, from the first base station and in response to receiving the acknowledgment, information indicating modification of the first TDD subframe configuration to a second TDD subframe configuration.

A method for controlling communications between a mobile device and a pair of base stations during a soft hand off mode of operation in a wireless system using HARQ is provided. In the soft hand off mode of operation, the mobile device communicates with a plurality of base stations and receives a plurality of feedback signals in the form of NACK and ACK signals from each of the plurality of base stations. The mobile device determines the reliability of each of these feedback signals, combines the reliable signals, and retransmits the old information if no ACK signals are received. On the other hand, the receipt of even one reliable ACK signal results in new data being delivered to the plurality of base stations.

The present invention provides a method of wireless telecommunication of a message having a block size. The method includes determining a number of retransmissions of the message based upon the block size.
摘要:
A method for controlling the flow of information between a UE and a Node B is provided. The UE transmits over a control channel to the Node B a signal requesting to transmit information to the Node B. The Node B uses information regarding a delay, such as a propagation and/or processing delay, associated with the UE to schedule the transmission of data. The UE then receives over a shared channel from the Node B a signal identifying a time at which the UE is permitted to transmit information. Thereafter, the UE transmits at the identified time over a data channel to the Node B a signal containing the information.
摘要:
A method of communication includes assigning at least one channelization code to a data packet. A portion of power available for communicating is assigned to the channelization code based on a channel quality metric. A system includes a transmitter, and an allocation unit. The transmitter is adapted to communicate data packets. The allocation unit is adapted to assign at least one channelization code to a data packet and assign a portion of power available for communicating to the channelization code based on a channel quality metric associated with the data packet.
