摘要： The present invention provides conversion between SDUs transmitted between a central network controller and base stations and PDUs transmitted between the base stations and mobile terminals. For downlink communications, SDUs are transmitted from the central network controller and forwarded to the base stations in an active set. One base station will break down the SDUs to create PDUs to transmit to the mobile terminal. For uplink communications, the base station will receive PDUs from the mobile terminal, create SDUs from the PDUs, and transmit the SDUs to the central network controller. During switching events, continuity information received from a previously serving base station is processed by the mobile terminal and used to create continuity information to send to the currently serving base station and used to determine the appropriate PDU from which to start transmissions to the mobile terminal after the switching event.
摘要翻译：本发明提供了在中央网络控制器和基站之间传输的SDU与在基站和移动终端之间传输的PDU之间的转换。对于下行链路通信，SDU从中央网络控制器发送并转发到活动集中的基站。一个基站将分解SDU以创建PDU以向移动终端传输。对于上行链路通信，基站将从移动终端接收PDU，从PDU创建SDU，并将SDU发送到中央网络控制器。在切换事件期间，由先前服务的基站接收的连续性信息由移动终端处理，并用于创建连续性信息以发送到当前服务的基站，并且用于确定适当的PDU，从而在其之后开始传输到移动终端切换事件。

摘要： Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.

摘要： One or more relay stations may be employed along a wireless communication access path between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add scheduling information to the PDUs before they are delivered to the downstream intermediate relay stations or egress stations. The scheduling information is used by the downstream stations to schedule the PDUs for further delivery. The scheduling information may also be used by the egress station to schedule the PDUs for delivery. The scheduling information added to the PDU by the ingress station bears on a QoS class associated with the PDU, a deadline for the egress station to deliver the PDU, or a combination thereof.

摘要： Aspects of the present invention provide a multi-band hybrid Gigabit wireless communication system which is enabled by a number of different complementary access technologies to realize ubiquitous hyper-connectivity, true broadband, seamless operation and low power consumption. The system is capable of serving fixed, nomadic and mobile scenarios. The multi-band wireless system is a low power wireless system which operates m different frequency bands covering the spectrum from radio wave to optical wave by making use of both regulated bandwidths and unregulated bandwidths. Using low power distributed antenna and low power indoor and outdoor antennas enables the use of unregulated bandwidths as well as regulated bandwidths as the low power nature of the signals reduces the possibility of interference with the regulated use of the signals.

摘要： Systems and methods for providing distributed Automatic Repeat Request (ARQ) in a wireless communication system are described herein. In one embodiment, a relay station interconnects a base station of the wireless communication system and one or more mobile stations. A first ARQ process is performed for a first connection between the base station and the relay station. A separate second ARQ process is performed for a second connection between the relay station and a mobile station. In this manner, rather than having end-to- end ARQ between the base station and the mobile station, a distributed ARQ process is provided.

摘要： In some embodiments of the present invention there is provided a frame structure for transmitting an integer number of OFDM symbols in which some of the OFDM symbols are to be transmitted in a unicast format and some of the OFDM symbols are to be transmitted in a broadcast format. The frame structure includes partitioning of a frame into at least two portions to accommodate both unicast and broadcast modes in the frame. The frame structure is used for transmitting multiple frames in a serial manner from at least one transmitter. The unicast mode supports transmission of OFDM symbols from a single transmitter to a single receiver. The broadcast mode supports transmission of OFDM symbols from multiple transmitters to all receivers within range of the multiple transmitters. The multicast mode supports transmission of OFDM symbols from multiple transmitters to multiple receivers within range of the multiple transmitters.
