摘要： A basic idea is to employ multi-user detection (MUD) at the receiver side in a multi-hop network to concurrently decode multiple packets transmitted from multiple nodes (T1, T2), and prioritize among the correctly decoded packets to select one or more packets suitable for forwarding, and finally reply with a packet acknowledgement (ACK) to the corresponding transmitting node for each selected packet. In this way, the design choice of MUD is exploited in the forwarding procedure. It is furthermore beneficial to exploit also the diversity enabled by the existence of multiple relay nodes (R1, R2, R3). A transmitting node that transmits its data packet signal to multiple relay candidate nodes and then receives packet acknowledgements from at least two relay candidate nodes preferably performs a prioritization to select a suitable relay node. The transmitting node then transmits a forwarding order (FO) to the selected relay node, which takes on responsibility for forwarding the information to the next node.
摘要翻译：一个基本思想是在多跳网络中的接收机侧采用多用户检测（MUD）来同时解码从多个节点（T1，T2）发送的多个分组，并且在正确解码的分组中优先选择一个或多个适用于转发的分组，并且最后用每个所选分组的对应发送节点的分组确认（ACK）进行答复。以这种方式，在转发过程中利用了MUD的设计选择。此外，还有利于利用多个中继节点（R1，R2，R3）的存在实现的分集。将其数据分组信号发送到多个中继候选节点，然后从至少两个中继候选节点接收分组确认的发送节点优选地执行优先级选择合适的中继节点。然后，发送节点向所选择的中继节点发送转发顺序（FO），该中继节点负责将信息转发到下一个节点。

摘要： Systems and methods are provided for managing communications between two or more ad-hoc networks in a communication system. The systems and methods may have flexible communication time sharing of one or more nodes taking part in two or more ad-hoc networks. For example, the communication scheduling function for a node shared by two or more ad-hoc networks is provided with a generic functional architecture such that it may be located in a number of different locations. In one embodiment, a Bluetooth communication system includes an inter-piconet scheduling function having a JUMP mode introduced to distinctly identify a node to its neighbors as being shared with multiple ad-hoc networks. The jump mode may have one or more methods for managing the inter-network communications that may include: (1) predetermined fixed starting point and length communication windows, (2) time points with flexible starting points and communication window length, and/or (3) random starting time and length communication windows.

摘要： The present invention discloses a method in a wireless access network node for controlling a UE. The UE comprises at least two transmit antennas, and is capable of uplink transmit diversity. There is an antenna weight associated with each transmit antenna. First, the wireless access network node determines that the antenna weights of the user equipment may be controlled. Then, it creates a control signal that comprises control information and transmits it to the user equipment. The control information controls a UE autonomous selection of the antenna weights in the UE.

摘要： The present invention relates to a method and a user equipment for use in a wireless communication system that allow for improved uplink transmit diversity performance by using downlink measurements for making informed decisions on whether or not to change precoding vector for uplink transmission. The user equipment measures (32) downlink characteristics, such as received power, on a plurality of antennas of the user equipment. Based on the measured downlink characteristics a precoding vector for unlink transmission is determined (38). The determined precoding vector is then used to perform uplink transmission (31).
