    摘要： User grouping is employed to tradeoff the COMP forward link capacity and required reverse link feedback, which makes the design of COMP practical and flexible. A channel element, such as the large scale fading, is measured for each distributed transmitter (14, 16) and UE (18, 20) pair based on reference signals, and the network (10) receives this information as feedback in the reverse link. The COMP determines a maximum cross interference level α
    req that is affordable, based on the available reverse link capacity for feedback. If this maximum cross interference level α
    req is exceeded, geographically separate UEs (18, 20) are divided into as few groups as possible, with UEs (18, 20) within each group separated, and the groups are allocated different time/frequency resource blocks. The grouping is done with the constraint that the cross interference does not exceed α
    req .

    摘要： Uplink overhead is significantly reduced in a MU-COMP wireless communication network (10) by exploiting the dissimilarity of received signal strength in signals transmitted by geographically distributed transmit antennas (14, 16), as seen by receiving UEs (18, 20). Each UE (18, 20) calculates a quantized normalization measure of channel elements for a channel weakly received from a first transmitter (14, 16) to that for a channel strongly received from a second transmitter (14, 16). The quantized normalization measure may be modeled as a ratio of complex Gaussian variables, and quantized in phase and amplitude by making simplifying assumptions. The ratios are quantized, and transmitted to the network (10) using far fewer bits than would be required to transmit the full channel state information. The network (10) uses the quantized normalization measures to set the transmitter (14, 16) weights.

    摘要： In a radio network in which multiple base stations can communicate with multiple user terminals in a coordinated way, user terminals may be grouped into groups, each group representing a coordination scheme to be used for user terminals in the group. The groups may be chosen, for example, according to path loss or QoS requirements Preferably there are three groups requiring no coordination, multiuser coherent coordination and single user coherent coordination respectively. Grouping may be done dynamically according to one or more of the following factors: - the terminal's signalling overhead - the affordable processing complexity - the traffic load - the radio conditions. The grouping unit may be placed in one or more base stations or in any other suitable unit in the network.

    摘要： The present disclosure relates to a method of coordinated scheduling of a downlink transmission flow from a first radio network node (such as a radio network controller RNC) to a user equipment UE in a second radio network node (such as a Node B, an eNode B, a base station BS), the method comprising a step of : scheduling the downlink transmission flow so that the in-sequence delivery of the received data blocks can be kept in an acceptable level in the UE by adjusting a scheduling priority of the downlink transmission flow in the second radio network node. The method may further comprise steps of: estimating one or more buffer-related parameters based on buffered data for the downlink transmission flow from the first radio network node; and determining, based on the estimated one or more buffer-related parameter and/or one or more parameters associated with the operation status of the second radio network node, if the in-sequence delivery of the received data blocks to higher layers can be in an acceptable level in the UE.
