摘要： In order to provide efficient relaying of multicast data in a wireless network, the wireless network comprises a base station and a relay node. The relay node is configured for transmissions on the basis of a radio frame including one or more subframes for unicast transmission and one or more subframes for multicast transmission. In a multicast-only operating mode of the relay node, the base station transmits multicast data to the relay node in one or more subframes which are selectable from the one or more subframes for unicast transmission and the one or more subframes for multicast transmission. The relay node receives the multicast data as transmitted by the base station and transmits the received multicast data in one or more of the subframes for multicast transmission.

摘要： A radio base station, a relay node and a respective method therein are provided for communicating data to a user equipment, the relay node being associated with the base station, wherein a downlink transmission to the user equipment is scheduled on subframe(s) available for the base station. The method in the radio base station comprises detecting that at least a part of the available subframes are not needed for downlink transmission to the relay node; and un-reserving at least one of the not needed subframes. The method further comprises transmitting, to the relay node, a release notification message notifying the relay node of the unreserved subframes for enabling the relay node to use the unreserved subframes for downlink transmission.

摘要： The present invention is directed to a method for adjusting a guard period in a base station for a cellular wireless communication system. The base station is adapted to communicate in a frame structure comprising a downlink frame followed by the guard period followed by an uplink frame. The method comprises the following steps: measuring interference in dependence on time from at least one interfering base station; and adjusting an uplink frame start time within the frame structure in dependence on the measured interference. The invention also relates to a base station, a network management entity, a computer program product and a method for operating the network entity.

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.

摘要： 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： The present invention is directed to methods for adjusting a guard period in a cellular wireless communication system, to a base station adapted to adjust a guard period, and to a network management entity for adjusting a guard period. One method comprises the steps: obtaining (S1) an indication of at least one downlink frame for an interference measurement; transmitting (S2) during the at least one indicated downlink frame an interference signal; measuring (S3) interference at least during a part of the guard period succeeding the indicated downlink frame; and setting (S4) at least one of an end time of at least one subsequence.
