20130223271 | METHOD AND APPARATUS FOR SIGNALLING MEASUREMENT SIGNALLING - The eNB of a first cell being interfered by at least one second cell, obtains pattern information, from the eNB of the second cell or network configuration, indicating almost blank subframes that are configured by the eNB of the second cell or the network configuration; determines measurement signalling indicating subframes; and sends the measurement signalling to the UE. The UE in the first cell receives the measurement signalling from the serving eNB, the measurement signalling comprising at least one pattern information recommended by at least one second cell or network configuration, each of the pattern information indicating at least one almost blank subframe that is configured by the corresponding second cell; determines the resource used for measurement according to the measurement signalling; and carries out measurement on the determined resource. | 08-29-2013 |

20130242750 | Method And Apparatus For Search Space Configuration For Enhanced Physical Downlink Control Channel - In one embodiment, the method of configuring a common search space (CSS) for at least one user equipment (UE) in a wireless communication system with at least a first type of physical downlink control channel includes broadcasting at least one parameter of a common search space (CSS), none of the parameters being the number of orthogonal frequency-division multiplex (OFDM) symbols. In one embodiment, a method of configuring a default user equipment-specific search space (USS) for a user equipment (UE) in a wireless communication system with at least a first type of physical downlink control channel includes broadcasting at least one parameter of the default USS, none of the parameters being based on an identifier of the UE. The broadcasting may occur before UE-specific signaling. In one embodiment, a method of configuring or reconfiguring the USS may include transmitting at least one parameter of the USS with UE-specific signaling. | 09-19-2013 |
20130329636 | METHOD AND DEVICE FOR REQUESTING ALMOST BLANK SUBFRAMES IN HETEROGENEOUS NETWORKS - One embodiment of the invention provides a mechanism to assist the eNodeB of the second cell, for example macrocell eNodeB or femtocell eNodeB to determine the configuration of ABSs. To be specific, the eNodeB of the first cell sends a request signaling to the eNodeB of the second cell to inform of the requirement for ABSs. The eNodeB of the second cell receives the request signaling from the eNodeB of the first cell, and then it determines the pattern of ABSs and sends the pattern of ABSs in the form of bitmap through a signaling to the eNodeB of the first cell. As the requirement for ABSs is determined by the eNodeB of the first cell on the basis of the number of the UEs and/or the traffic load of the UEs which are near the edge of coverage area of the picocell, it can help the eNodeB of the second cell to determine the configuration of ABSs, i.e. the pattern of ABSs, so that the efficient resource utilization is achieved. | 12-12-2013 |
20140031046 | TRANSMISSION METHOD AND MOBILE STATION TO CARRY OUT THE METHOD - A method, in a cellular radio-communication system comprising a core network and an access network, the access network comprising base stations for providing wireless links to at least one mobile station, the mobile station being capable of operating in a first transmission mode in which beamforming transmit diversity is not used and in a second transmission mode in which beamforming transmit diversity is used. The method comprises switching from the second transmission mode to the first transmission mode upon determining that at least one predetermined criterion related to the mobile station operation in soft handover is satisfied. | 01-30-2014 |

20140287763 | INTERFERENCE REDUCTION - A method of reducing inter cell interference in a wireless communication network, a network control node, network access node, user equipment and computer program product operable to implement that method. The method is for use in a network comprising a plurality of network access nodes, each supporting a region of radio overage, and the method comprises: discovering, for a first network access node, at least one adjacent network access node; allocating at least one predetermined shared radio channel for radio communication commenced within an overlapping radio coverage region between said first network access node and said adjacent network access node; and communicating an indication of said at least one predetermined shared radio channel to said first network access node and said adjacent network access node. The method enables shared radio channels to be used in a “soft handover” type scenario, by enabling adjacent network access nodes to decipher and decode transmissions made by user equipment operating in overlap regions in a network. Such methods may be particularly suited to user equipment operating in a Cell_FACH mode. | 09-25-2014 |
