摘要： Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network. These embodiments can advantageously be deployed in dense urban areas and/or co-located with wireless access nodes, such as base-stations of a cellular wireless communication system. Preferably wireless links between constituent network nodes are set-up hierarchically. A basic result of this is that peer-to-peer (child-to-child) communication is generally prohibited and circuits are forced to conform to a topology. The multi-hop wireless backhaul network may be used to carry delay sensitive, high-density last mile circuit traffic over Non-Line-Of-Sight (NLOS) broadband radio links. Moreover, some embodiments of the invention provide a method of path-healing for re-routing of circuit traffic from circuits that have experienced catastrophic failures.

摘要： A base station in a wireless communications system defines a plurality of beams which each have an amount of resources for supporting communication links with terminals. A control entity determines if a direct communication link can be supported between a new terminal and a base station using a first beam. If a direct communication link cannot be supported, a relaying equipment is used to provide a multi-hop path between the base station and the terminal. The multi-hop path comprises a link between the base station and the relaying equipment using resources of a different beam. This helps to redistribute load within the cell. The direct communication link can be refused if there are insufficient resources in the first beam, or if accepting the new terminal would cause quality of communication links with existing terminals to deteriorate.

摘要： A wireless network includes a base station which can serve terminals directly, or via multi-hop transmission paths via relay stations. The base station transmits a downlink sub-frame which includes a first set of frame control information and a second set of frame control information. The second set of frame control information occupies a different position within the downlink sub-frame compared to the first set of frame control information. A relay station is able to transmit a downlink sub-frame to a terminal, or another relay station, while still being able to receive a set of frame control at a different time during the downlink sub-frame. The invention is especially useful in a wireless network in which the downlink transmissions of a base station and a relay station are synchronized to one another and where the downlink transmissions of a base station and relay station occupy the same, or similar, frequency bearer.

摘要： 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.

摘要： 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.
摘要翻译： 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。 4。 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。
