Abstract: A method and system for providing CoMP assistance in a wireless communication network are disclosed. In one embodiment a cooperating base station receives a CoMP assistance request from a serving base station. The CoMP assistance request is a request for assistance to decode a first transmission from a UE. The cooperating base station receives the first transmission from the UE. The first transmission from the UE is received at the cooperating base station at one of a time before receiving the CoMP assistance request and a time after receiving the CoMP assistance request. The cooperating base station determines a CoMP payload in response to the CoMP assistance request. The CoMP payload is based on the received first transmission from the UE. The CoMP payload is forwarded to the serving base station after the serving base station determines that the first transmission from the UE is received by the serving base station with error.

Abstract: The base stations in a coordinating set, i.e., CoMP set, implement distributed V-MIMO processing to decode uplink signals transmitted from multiple user terminals over the same time and frequency resources. Each base station uses the extrinsic information received from its coordinating base stations to facilitate demodulation and decoding. In the event that one of the base stations successfully decodes an uplink signal, it may provide the decoded data to the other coordinating base stations in the coordinating set. In this case, the coordinating base stations do not need to decode the uplink signal. Even if the uplink signal is not successfully decoded, the demodulated data received from the coordinating base station increases the likelihood of successfully decoding uplink signal in the next iteration of a HARQ process.

Abstract: A method and system for adaptive coordinated multipoint support in a wireless communication system are disclosed. According to one aspect, the invention provides an uplink coordinated multipoint, CoMP, method. A CoMP request is received at a cooperating base station from a serving base station. The CoMP request specifies a first CoMP payload type. Responsive to receiving the CoMP request, a second type of CoMP payload to provide to the serving base station is provided. The second type of CoMP payload is determined based at least in part on resource usage. The cooperating base station provides a CoMP payload of the determined second CoMP payload type to the serving base station.

Abstract: Methods and apparatus are provided for determining a set of cooperating cells for a mobile terminal in a mobile communication network for CoMP transmission or reception. A cell map is stored in memory of serving base station. The cell map associates one or more coordinating areas within the serving cell with corresponding sets of neighboring cells. To determine the set of cooperating cells for a given mobile terminal within a serving cell, the serving base station determines the current location of the mobile terminal. The current location of the mobile terminal is compared to the cell map stored in memory to determine the coordinating set for the mobile terminal.

Each task is performed by the baseband processor at a time that is based on the priority assigned to the task.

Abstract: A method for providing a radio architecture for a long term evolution (LTE) communication system is disclosed. According to one aspect, a radio provides power pooling and direct up-conversion of signals to be transmitted. Power pooling is provided by adjusting the gain and phase of each of a plurality of carrier signals in a digital matrix based on feedback signals received from an analog matrix, such that the output signals are coupled to one or more selected radio output ports. Direct up-conversion is achieved by up-sampling and filtering the carrier signals to be transmitted.

Abstract: In an OFDM system, frequency domain processing is carried out by the control node. The frequency domain data is scrambled and transmitted over a packet-based interface to a transmitting node. The transmitting node unscrambles the frequency domain data and converts the frequency domain data to time domain data. The time domain data is used to modulate an RF carrier to generate a transmit signal for transmission over a wireless communication link to one or more mobile terminals.

Abstract: Embodiments herein provide reduced backhaul bandwidth requirements for Coordinated Multi-Point reception of an uplink signal. A cooperating base station receive and demodulates the uplink signal to produce soft output values that each indicate the value of a corresponding information symbol in the uplink signal and the level of certainty in that symbol value. The cooperating base station then selectively sends particular ones of the soft output values to a serving base station over a backhaul communication link based on whether or not the level of certainty indicated by each soft output value exceeds a certainty threshold. The serving base station likewise receives and demodulates the uplink signal to produce its own soft output values. The serving base station then combines respective ones of the soft output values it received from the cooperating base station and the soft output values it produced itself that are associated with the same information symbol.
