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： 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： The present invention provides a method, a radio base station (40) and a mobile terminal (50) for allocating resources in a telecommunications network, where communications between the radio base station (40) and the mobile terminal (50) take place over a plurality of carriers. The method comprises transmitting and receiving a resource allocation message comprising one or more bits. Each of the bits corresponds to a number of resource blocks, where the number is determined from the ratio of the aggregate bandwidth of the plurality of carriers divided by the bandwidth of the carrier over which the resource allocation message is sent.

摘要： In a heterogeneous cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node.

摘要： Mechanisms to provide independent DRX (discontinuous reception) functionalities for individual carriers of a multi-carrier wireless network (200) are described. DRX is a higher layer functionality indicating which TTIs (transmission time intervals) a user equipment (220) needs to read for control signals. Operating in the DRX cycle allows the user equipment (220) to reduce battery consumption. A connection is established between a base station (210) and the user equipment (220) over a plurality of carriers, where for each carrier, an independent DRX cycle is established. The plurality of carriers include anchor carriers which can carry commands from the base station (210). The anchor carriers have shorter DRX cycles than the non-anchor carriers. When a large amount of download data is to be transferred, the DRX cycles of multiple carriers are overridden and used for transfer to achieve fast download rates. The override commands are sent from the base station (210) to the user equipment (220) prior to the transfer.
