    • A mobile telephony network comprises base stations operating according to a predetermined standard. A transfer node allows the transfer of data from a first base station to a second base station in the mobile telephone network. Data is sent from the first base station to a data receiver of the data transfer node via a first wireless communications channel complying with the said standard. The received data is transferred via an interface within the transfer node to a data sender of the data transfer node. The data sender sends the transferred data to the second base station via a second wireless communications channel complying with the said standard. The interface within the transfer node does not comply with the operating standard because it transfers data only within the node. Data may be sent from the second base station to the first base station via the node in similar manner. Preferably, the receiver appears to the first base station to be a relay and the sender appears to the second base station to be a user terminal.
    • 移动电话网络包括根据预定标准操作的基站。 传输节点允许将数据从第一基站传输到移动电话网络中的第二基站。 数据经由符合所述标准的第一无线通信信道从第一基站发送到数据传输节点的数据接收机。 所接收的数据经由传输节点内的接口传送到数据传输节点的数据发送者。 数据发送器通过符合所述标准的第二无线通信信道将传送的数据发送到第二基站。 传输节点内的接口不符合操作标准,因为它仅在节点内传输数据。 数据可以以类似的方式经由节点从第二基站发送到第一基站。 优选地,接收机在第一基站看起来是中继,并且发送方对第二基站看起来是用户终端。

    • Allocate power so as to maximise the throughput of each user of a multi-user MIMO group, with the constraint that over time all users in the group have equal throughput. This differs from equal capacity per slot in that each user may be assigned multiple slots as well as unequal power. This is illustrated in FIG. 4. Total throughput is maximised on any given slot for any two users. Power is shared between the spatial modes such that the total number of slots used by the two users is minimised. The membership of the MIMO group may change between slots and thus throughput is not necessarily equalised on a slot by slot basis.
    • 分配功率以便最大化多用户MIMO组的每个用户的吞吐量,并且具有随着时间的推移,组中的所有用户具有相等的吞吐量。 这与每个时隙的等容量不同,因为每个用户可能被分配多个时隙以及不相等的功率。 这在图1中示出。 任何两个用户的任何给定插槽的总吞吐量最大化。 在空间模式之间共享功率,使得两个用户使用的时隙的总数最小化。 MIMO组的成员资格可以在时隙之间改变,因此吞吐量不一定在逐个时隙上均衡。

    • Methods, systems and apparatuses are provided for transmitting and receiving space-time block coded data in a wireless communications system with co-operative relays. A source node transmits RF signals representing first and second sets of data symbols in respective first and second channels (in time frequency code or any combination) of a wireless communications system, the first and second sets of data symbols being for transmission from separate antennas respectively according to a space-time block code. A relay node receives the RF signals representing the first set of data symbols in the first channel and transmits RF signals representing the first set of data symbols in the second channel. A destination node received the RF signals representing the second set of data symbols from the source node and the RF signals representing the first set of data symbols from the relay node. This enables decoding of the received RF signals representing the first and second sets of data symbols according to the space-time block code.

    • The capacity of a cellular wireless system is increased by operation of base stations or base station sectors arranged to re-use radio resource elements that are used by neighbouring base stations or base station sectors, in conjunction with operation of relay stations, which are similarly arranged to re-use radio resource elements used by neighbouring relay stations, and where the radio resource elements re-used by the relay stations are different to those used by the base stations. The relay stations provide coverage, particularly in the areas at the boundaries between the areas of coverage of base stations that suffer from interference between signals transmitted from the respective base stations. In addition, the relay stations generally increase the average available carrier to interference ratio compared with a system in which base stations alone are deployed. The scheme for the allocation of radio resource elements ensures in particular that interference is avoided between signals transmitted from a base station and signals transmitted from a relay station in radio resource elements allocated to control data.

    • Embodiments of the invention relate to wireless communications networks, and more specifically to method and apparatus relating to wireless backhaul for cellular wireless systems. Increasing data capacity of cellular wireless systems places increasing demands on the capacity of the two way connection, known as backhaul, between a cellular base station and a telecommunications network such as the PSTN backhaul, since this is the connection that has to convey the wireless-originating traffic to its destination, often in an entirely different network. Known backhaul links include leased lines, microwave links, optical fibre links or radio resources for relaying backhaul traffic between base stations. The fixed line solutions are expensive to implement and maintain, while the radio solutions suffer from interference from transmissions between base stations with transmissions from user equipment to base stations which are not communicating with other base stations. In embodiments of the invention, the relaying of access data between base stations utilises radio resources other than radio resources used by transmissions from user equipment within an area of contiguous wireless coverage. The benefit of this approach is that it provides a means of avoiding interference between inter-base station transmissions and user equipment to base station transmissions.
    • 本发明的实施例涉及无线通信网络,更具体地涉及与蜂窝无线系统的无线回程相关的方法和装置。 蜂窝无线系统的数据容量的增加对于诸如PSTN回程的蜂窝基站和电信网络之间的双向连接(称为回程)的容量的需求增加,因为这是必须传送无线 - 将流量发送到目的地,通常在完全不同的网络中。 已知的回程链路包括专线,微波链路,光纤链路或无线电资源,用于在基站之间中继回程业务。 固定线路解决方案在实施和维护方面是昂贵的,而无线电解决方案受到来自基站之间的传输的干扰以及从不与其它基站通信的用户设备到基站的传输。 在本发明的实施例中,基站之间的接入数据中继使用无线电资源,而不是无线电资源使用的无线电资源来自用户设备在连续无线覆盖范围内的传输。 这种方法的优点在于它提供了一种避免基站间传输与用户设备之间基站传输干扰的方法。
