Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, are configured for spreading, using a first data spreader, first data into a first data frame using a first spreading factor. A first transmitter transmits the first data frame to a diplexer on a first frequency. A second data spreader spreads second data into a second data frame using a second spreading factor. A second transmitter transmits the second data frame to a diplexer on a second frequency different than the second frequency. A diplexer combines the first data frame and the second data frame. A first receiver receives on the first frequency, a third data frame from the diplexer. A second receiver receives on the second frequency a fourth data frame from the diplexer.

Abstract: A method includes a base station in a distributed antenna system having a set of antennas. For each antenna, the base station stores state information indicating that the antenna is either in a transmit state or a do_not_transmit state. For each antenna indicated by the state information for the antenna as being in the transmit state, the base station determines whether the antenna has been given a clear channel indication (CCI) for a next transmission time interval (TTI). At the next TTI, the base station transmits data to a UE, wherein the base station transmits the data to the UE using antennas included in said set of antennas that i) are indicated by the state information for the antenna as being in the transmit state and ii) have been given the CCI. The base station adjusts the state information in accordance with a transmit status.

Abstract: A method and apparatus for transmitting a training sequence code of a transmitting apparatus with a plurality of transmitting antennas in a communication system are provided. A transmitting apparatus allocates a plurality of time slots for the plurality of transmitting antennas to be divided into at least one frame, and sends a training sequence code with reference power for any one of the transmitting antennas, and sends remaining training sequence codes for remainders of the transmitting antennas with transmission power from zero to the reference power, in any one of the time slots. A receiving apparatus receives a plurality of training sequence codes for a plurality of transmitting antennas through any one of the plurality of receiving antennas from a transmitting apparatus, and selects one of the training sequence codes having the greatest reception power to estimate a channel. This may improve a channel estimation performance in a communication system.

Abstract: Techniques for encoding a phase adjustment for a feedback signal in a closed-loop transmit diversity system. In an aspect, codewords for the phase adjustments are chosen according to a variable-length prefix code. The prefix code aspect allows the codewords to be transmitted in sequence on the feedback channel without being separated by "commas" or demarcation symbols. The variable-length aspect provides a variety of coarse and fine phase adjustment quantization step sizes to accommodate multiple different channel scenarios. In an aspect, the length of the codewords may be further optimized according to the Huffman encoding algorithm.

Abstract: Providing for fair resource sharing among wireless nodes in a wireless communication environment is described herein. By way of example, fairness can comprise establishing a set of resource sharing credits for wireless nodes. By expending credits, a node can borrow a resource of another node, to enable or enhance operation of the borrowing node. Credits for the borrowing node are decreased based on consumption of a shared resource, or credits for the lending node are increased based on such consumption, or both. Once an amount of credits expires, a node can be restricted from borrowing further resources until enough resources are lent to build up a suitable amount of credits. Accordingly, fairness can comprise correlating shared resource consumption with shared resource provisioning, to encourage participation in cooperative wireless communications.

Abstract translation: 本文描述了在无线通信环境中的无线节点之间提供公平的资源共享。 作为示例，公平性可以包括为无线节点建立一组资源共享信用。 通过消耗积分，节点可以借用另一个节点的资源，以启用或增强借用节点的操作。 基于共享资源的消耗，借用节点的贷方减少，或者基于这样的消费增加贷款节点的贷款，或两者。 一旦一定数量的信用额到期，一个节点可以被限制借用进一步的资源，直到足够的资源被借出来建立一个合适数量的信用。 因此，公平性可以包括将共享资源消耗与共享资源供应相关联，以鼓励参与协作无线通信。
