摘要： Error protection based on a nonlinear code set may be used in a multiple input multiple output (MIMO) radio communications system. A decoder decodes received MIMO data streams and generates an automatic repeat request (ARQ) message for data units received for the MIMO data streams for each transmission time interval. An encoder codes the ARQ message using a code word from a nonlinear code set. At the data transmitter, which transmits one or more data units in transmission time intervals from two or more MIMO data streams, the ARQ message associated with the transmitted data units is decoded using a code word from the nonlinear code set.

摘要： Method and apparatus in a communication unit (400) employing a wireless TDD or half duplex FDD transmission arrangement when communicating with a data sending party, for scheduling feedback reports for data blocks in received RX sub-frames, in TX sub-frames available for transmission. An obtaining unit (402) in the communication unit receives allocation parameters (P) for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit (404) in the communication unit then schedules feedback reports (FR) in available TX sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames. In this way, the number of feedback reports in a TX sub-frame can be reduced.

摘要： The invention relates to a method in a first communication device of receiving control information over a radio channel from a second communication device. The first communication device receives a subframe over the radio channel, and determines whether the subframe is a downlink subframe with downlink assignment intended for the first communication device by reading data in the subframe. That being the case, the first communication device decodes data within the subframe, and determines whether any data packet being sent from the second communication device before the subframe has been missed by analysing an indicator associated to the subframe in the data. The indicator provides knowledge about previous downlink subframes with downlink assignment intended for the first communication device.

摘要： The present invention relates to methods and arrangements in a multi-carrier system. It also assumes independent DRX (Discontinuous reception) functionality on respective component carriers and the possibility for one carrier, e.g. the anchor carrier to initiate a change of DRX state for another component carrier. The basic concept of the present invention is to introduce a new “dormant” state in the DRX logic, whereby the dormant state can be used for non-anchor carrier components. The dormant DRX state implies that a carrier of a UE having this state is not required to monitor system signaling. In embodiments of the present invention this new state is introduced for a particular component carrier (e.g. non-anchor component carrier) for a UE operating in a multi-carrier system, and how to perform the transitions to and from the dormant DRX state implicitly, e.g. based on configured timer(s) for the component carrier or explicit signaling in a different (e.g. anchor) component carriers.

摘要： A method for scheduling resources for uplink transmissions in a radio access network includes each of a plurality of access points (APs) placing its resources to the disposition of other APs and transmitting a blocking signal if it does not allow other APs to use any of its resources. The method includes a user terminal (UT) listening for blocking signals and an AP scheduling the UT on the AP's own resources and/or on resources belonging to one or more other APs.

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： For wireless networks that transmit synchronization signals allowing user equipment to synchronize to cells within the network and transmit reference signals allowing user equipment to determine cell identities, a method and apparatus taught herein advantageously link the synchronization signal sequences to the reference signal sequences according to a defined mapping. The linking simplifies the cell search process by allowing user equipment to determine cell identities based on mapping detected synchronization signal sequences to the corresponding reference signal or to the corresponding subset of reference signals in embodiments where there are more reference signal sequences than synchronization signal sequences. In at least one embodiment, the network is a 3G LTE network and at least the Primary Synchronization Signal (P-SyS) sequences are linked to the Downlink (DL) reference symbol sequences according to a defined mapping, thereby allowing to user equipment to determine cell identities from detected P-SyS sequences.

摘要： Teachings herein schedule a data transmission in a variable bandwidth wireless communication system based on the power efficiency of a mobile node. One or more processing circuits, of the mobile node or a network node, determine the value of a control setting that defines a power efficiency configuration of the mobile node. In one embodiment, for example, the power efficiency configuration indicates the mobile node is configured to operate at the maximum power efficiency attainable without the data rate of the data transmission falling below a minimum data rate required by a quality of service. Regardless, the one or more processing circuits select from different possible bandwidths of the data transmission a bandwidth that supports a given data rate and that, according to a power efficiency model that models power efficiency of the mobile node for the different possible bandwidths, yields a power efficiency comporting with the power efficiency configuration.

摘要： Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal (200) is configured to effectively ignore ‘UP’ transmit power control commands in the event that the mobile terminal (200) is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal (200), a plurality of transmit power control commands are received. An accumulated power control value is adjusted (350) in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted (350) in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal (200) is not in a power-limited state. Transmit power settings for each transmission are calculated (360) based on the accumulated power control value and the one or more radio link parameters.
