摘要： A method of providing signal synchronization for a radio access network may include transmitting a first carrier including synchronization signals on a first frequency from the radio access network. Information relating the first carrier on the first frequency with a second carrier on a second frequency may be transmitted from the radio access network, with this information being intended to be used in synchronization by a wireless terminal upon addition of the second carrier. More particularly, the first and second frequencies may be different. A command to add the second carrier as a downlink for transmissions may be transmitted to the wireless terminal. Related network nodes and wireless terminals are also discussed.

摘要： A cellular communications system that utilizes OFDM in its radio interface is capable of utilizing either a first subcarrier spacing or a second subcarrier spacing. Which of these is presently in use is indicated by generating a first type of synchronization signal in response to the first subcarrier spacing presently being in use, and generating a second type of synchronization signal in response to the second subcarrier spacing presently being in use. Whichever of the first type of synchronization signal and the second type of synchronization signal was generated is transmitted. To distinguish between the first and second types of synchronization signals, a time domain representation of the second type of synchronization signal includes a plurality of instances of the first type of synchronization signal.

摘要： A method in a radio network node for dynamic carrier mode switching is provided. The radio network node is comprised in a radio communications system. The radio network node is configured to operate in a legacy mode and is further configured to operate in a non legacy mode. At least one carrier is operated so that it switches (602) from non legacy mode to legacy mode. When operating the carrier in the legacy mode, the radio network node signals (603) with a user equipment. The user equipment operates in legacy mode, but can not operate in non legacy mode. The radio network node then operates the at least one carrier so that it switches (604) from legacy mode back to non legacy mode.

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： 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： 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.
