摘要： Methods and devices for managing a cellular communication system (1) and mobile terminals (40) are presented. A collective positioning measurement order (50) is issued to a multitude of mobile terminals (40) in a first cell (10) of the cellular communication system (1). This issuing is preferably performed intermittently at a multitude of times according to a predetermined rule. Each mobile terminal (40) receives information concerning a collective positioning measurement order.

摘要： The invention relates to a method and arrangement for transmitting and receiving control information in a radio-access network. A network node transmits first control information in a first part and second control information in a second part of a time-frequency region that is transmitted after a control region in a subframe. The second part is located later in the subframe than the first part. The second control information may be less time-critical than the first control information. An intermediate node receives and decodes the first control information at the end of the first part. When the first control information indicates that the subframe comprises data payload to the intermediate node, the intermediate node receives and decodes the data payload. The intermediate node receives second control information at the end of the second part.

摘要： Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits.The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence across Discrete Fourier Transform Spread-Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The UE further transforms the block-spread sequence, per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS-OFDM symbol index and/or slot index to the block-spread sequence. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.

摘要： The technology disclosed provides the ability for a subframe to be configured as a “flexible” subframe. As a result, at least three different types of subframes in a TDD system may be configured: a downlink (“DL”) subframe, an uplink (“UL”) subframe, and a “flexible” subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.

摘要： Methods and arrangements for resource allocation in a telecommunication system in which aggregation of component carriers is applied. The size of the resource allocation field is determined based on the transmission bandwidth of a selection of component carriers. The selection of component carriers comprises the component carrier on which the resource allocation message is monitored and the component carriers which are cross-scheduled from said component carrier. The resource allocation message comprising the resource allocation field with the determined size is transmitted to the user equipment over a particular component carrier of the selection of component carriers. Furthermore, with only one size of the resource allocation field a smaller number of code word sizes needs to be monitored by the UE. This leads to a smaller number of blind decodings performed in the UE. The present invention enables a more tailored approach when determining the size of the resource allocation field to avoid too high overhead but also a too coarse resource allocation.

摘要： A method in a network node for transmitting control information to a user equipment in a telecommunications system is provided. The control information is scheduled in time intervals of a downlink shared data channel, wherein the control information is allocated resource elements in resource blocks of a time-frequency Orthogonal Frequency Division Multiplexing, OFDM, grid in the time intervals in which the control information is scheduled. The network node determines for a time interval, a set of user equipments for which control information is scheduled in the time interval. Also, it selects for a user equipment comprised in the determined set of user equipments, at least one group of user equipments amongst one or more groups of user equipments to which the user equipment is assigned. It also prepares a group signal corresponding to the selected one group of user equipments by allocating resource elements in the resource blocks of the time interval to the group signal. Furthermore, the network node transmits the prepared group signal in the allocated resource element in the time interval to the user equipment such that the user equipment is enabled to determine whether the control information that is allocated resource elements in the time interval is intended for the user equipment or not.A network node, a method in user equipment and a user equipment are also provided.

摘要： Method and apparatus for conveying feedback reports from a data receiving party (300) for data received from a data sending party (302) in a wireless connection. A plurality of feedback resources (304) assigned to different feedback information codes are allocated to the data receiving party for transmitting feedback reports. After checking whether the data was received correctly or not, the data receiving party selects a feedback resource (FR2) with a feedback information code that corresponds to one or more feedback reports on the received data. The data receiving party then sends feedback information on the selected feedback resource to the data sending party, thereby conveying the corresponding feedback information code. In this way, multiple feedback reports can be conveyed in a single feedback resource to the data sending party while still retaining single carrier properties.

摘要： The present invention relates to cellular radio communication and in particular to providing information on neighbor cells to enable terminals to perform neighbor cell measurements. In the prior art the terminal attempts to make neighbor cell measurements in a reference signal structure that is the same in the neighbor cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighboring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbor cells.
