An indication of non-receipt of one of the plurality of data blocks is received from the second device, which leads to a retransmission pending timer being started if a retransmission pending timer is not already running. The first device records for which of the data blocks an indication of non-receipt has been received whilst the timer is running, and notes for which of those initially non-received data blocks an acknowledgement of receipt is subsequently received. At expiry of the timer, the first device retransmits those of the data blocks that have a sequence number less than the sequence number of the data block that led to the timer being started and for which an indication of non-receipt was received whilst the timer is running and an acknowledgement of receipt was not received. | 05-09-2013 |

20130114518 | METHODS AND APPARATUSES FOR OVERRIDING COMMON ENHANCED DEDICATED CHANNEL RESOURCE SELECTION - A method, apparatus and computer program product are provided for overriding requests for a selected communication resource and indicating a different resource(s) for communication. A method and apparatus may select a communication channel resource type associated with a first set of resources based in part on determining that a predetermined condition is met and may provide a message, to a network device, requesting usage of the selected communication channel resource type. The method and apparatus may also receive a response, from the network device, denying the request for the selected communication channel resource type. The method and apparatus may also cause selection of another communication channel resource type associated with a second set of resources and providing a generated request to the network device requesting usage of the second type of communication channel resource type. | 05-09-2013 |

20130114430 | Devices and Methods Related to Controlling UE Assumption of Interference - To control UE assumption of interference there is a controller module to control a plurality of transmission points, each constituted by a set of at least one transmit antenna, to transmit data to another device in a coordinated transmission from at least a subset of the plurality of transmission points. The controller module is configured to allocate, to each resource linked to the subset of the plurality of transmission points, an interference contribution parameter that is indicative of an expected interference contribution originating from said transmission point, and to inform said another device of those resources to which the subset of the plurality of transmission points is linked, together with the respective interference contribution parameter allocated to each resource. Another device reports feedback based on signals which are scaled with the respective interference contribution parameter. | 05-09-2013 |

20130114427 | Cooperative Multipoint Scheme Selection Codebook - A network sends to a user equipment UE a reference signal configuration, and from receiving it the UE selects a codeword identifying a cooperative multipoint CoMP transmission scheme. There is a CoMP scheme selection codebook from which the UE selects the codeword corresponding to its recommended CoMP scheme. The UE sends to the network that codeword which identifies the CoMP transmission scheme, along with the CSI feedback characterizing the CoMP transmission scheme. From that codeword which the network receives it determines the UE's assumed CoMP transmission scheme, which the network uses to determine how the CSI feedback, received from the UE, was calculated by the UE (for example, joint transmission, or dynamic point selection with or without muting, or coordinating scheduling/beamforming). The network uses this information for selecting a CoMP transmission scheme for downlink CoMP transmissions to the UE. | 05-09-2013 |
20130114418 | METHODS AND APPARATUS FOR WIRELESS COMMUNICATION - The invention relates to methods, apparatus and computer program products for enabling mobility in a downlink packet access service in a wireless communications network. At a user equipment, packet data is received from a set of one or more serving downlink shared channel cells simultaneously via one or more respective shared downlink channels and a measurement report associated with the downlink packet access service is transmitted to the network. The service is capable of initiating an addition or removal of at least one, or replacement of any, of the serving downlink shared channel cells in the set on the basis of the transmitted measurement report. | 05-09-2013 |
20130114401 | METHOD AND APPARATUS FOR RESELECTING A DIFFERENT TRANSMISSION TIME INTERVAL RESOURCE - A method, apparatus and computer program product are provided in order to allow for reselection of a TTI resource, such as in an instance in which a mobile terminal has moved to a different portion of the coverage area and/or in an instance in which the TTI resource was initially incorrectly selected, such as based upon an inaccurate measurement.
