摘要:
In communication of data between a first base station and a mobile terminal, a second base station may handle uplink transmissions from the mobile terminal. For this purpose, the first base station sends, to the second base station, a request to handle the uplink transmissions from the mobile terminal. The handling of the uplink transmissions to be performed by the second base station includes scheduling of the uplink transmissions so as to obtain uplink scheduling information. Via a backhaul link, the second base station transmits the uplink scheduling information to the first base station. The first base station includes the uplink scheduling information into downlink transmissions to the mobile terminal.

In communication of data between a first base station and a mobile terminal, a second base station may handle uplink transmissions from the mobile terminal. For this purpose, the first base station sends, to the second base station, a request to handle the uplink transmissions from the mobile terminal. Further, the first base station sends carrier information to the second base station. The carrier information indicates one or more uplink carriers for receiving the uplink transmissions. The one or more uplink carriers are controlled by the second base station. Moreover, the first base station sends downlink transmissions to the mobile terminal. The downlink transmissions include configuration data. By means of the configuration data, the mobile terminal is configured to send uplink transmissions on the one or more uplink carriers as indicated by the carrier information, e.g., on an uplink payload channel controlled by the second base station.

Method for performing a feedback process between a network access node and a user terminal, comprising collecting supporting information and suspending a transmission of a transport block until the supporting information is collected and/or a decision is taken as to whether request either a new transmission or a retransmission. The method may be performed in a serving network node cooperating with supporting network nodes, receivers or antennas, wherein a first part of the information of the transport block is gathered from a receiver or antenna within the serving network node and a second part of the information of the transport block is gathered from one of the supporting network nodes, receivers or antennas.
摘要:
With respect to cooperative signal communication between a mobile terminal (200) and a plurality of access nodes (100-1, 100-2), a combined signal quality value is calculated on the basis of a first individual signal quality value (Q1) of a communication link between a first access node (100-1), e.g. a serving base station, and the terminal (200), and a second individual signal quality value (Q2) of a second communication link between a second access node (100-2), e.g. a supporting base station, and the terminal (200). On the basis of the combined signal quality value, a transmission parameter (50) for future cooperative transmissions is adapted. The transmission parameter (50) may be a modulation scheme, a coding scheme, a transmit power, or a resource allocation.
摘要:
In cooperative signal communication between a mobile terminal (200) and a plurality of access nodes (100-1, 100-2, 100-3), cooperation signals (20), e.g. received signals or signals to be transmitted, are communicated with the access nodes (100-1, 100-2, 100-3). The cooperation signals (20) are quantized according to a quantization parameter, e.g. quantization depth and/or quantization type, which is adapted on the basis of a cooperative communication parameter. The cooperative communication parameter is a characteristic of the cooperative communication process, e.g. modulation scheme.

A technique for assigning transceiver devices to transmission resources for inter-cell interference coordination in a heterogeneous cellular communication network is described. The network comprises a first cell layer having a first cell associated with a first transmission resource and a second cell layer having a second cell associated with a second transmission resource disjunctive from the first transmission resource. In a method implementation, the technique comprises performing a first selection procedure to select a first set of transceiver devices served in the first cell based on the potential of causing interference to transceiver devices served in the second cell, performing a second selection procedure to select a second set of transceiver devices served in the second cell based on the potential of being sensitive to interference from transceiver devices served in the first cell, and assigning the first set of transceiver devices to the first transmission resource and the second set of transceiver devices to the second transmission resource.
摘要:
In downlink signal communication to a mobile terminal (200), the mobile terminal (200) is associated with a serving access node (100-1). Signal communication to a further mobile terminal (200; 200′″) may interfere with the signal communication between the serving access node (100-1) and the mobile terminal (200). In order to allow interference mitigation at the mobile terminal (200), the serving access node (100-1) obtains scheduling information pertaining to the signal communication to the further mobile terminal (200; 200′″). The obtained scheduling information is then forwarded to the mobile terminal (200) to be used for interference mitigation.
