摘要： A method and system for controlling access to a medium in a wireless communication system. A superframe structure is defined in time domain to include a contention free period (CFP) which has at least one scheduled resource allocation (SRA) (3712), at least one management SRA (MSRA) (3718) and a contention period. An extended beacon (EB) (3746) including information about the SRA and MSRA is transmitted for. The architecture reduces station battery consumption, supports higher throughput for non-real time (NRT) traffic and is more efficient for real time (RT) traffic while maintaining full compatibility.

摘要： A method and system for eliminating interference caused by hidden nodes is disclosed. An initiator control message is defined for an initiator, (typically a wireless station (STA)), in order to begin an aggregate frame exchange with at least one responder. The initiator control message includes information on the queue sizes at the initiator. A responder, (typically an access point (AP)), sets up the required protection for the transmission of data by the initiator based on information on the queue sizes indicated in a field of the initiator control message using a responder control message. Other STAs that receive the responder control message set parameters for a wireless medium access accordingly. In another embodiment, multiple receiver aggregate multi-poll (MMP) and power save aggregation descriptor (PSAD) control frames are configured for transmission by a non-AP STA to provide enhanced scheduling and mitigate hidden node problems.

摘要： A peer-to-peer communication system using a direct link setup (DLS) is disclosed. A mobile station (STA) establishes a direct communication link with another STA by sending a message requesting a DLS to an access point (AP), (i.e., a centralized controller). The AP may accept or reject the DLS request based on channel measurements. If the DLS request is accepted, the DLS is established such that the STAs may directly communicate with each other. An established DLS connection may be torn down by the AP sending a message including a DLS teardown request to one of the STAs, or based on channel measurements. The system may be an Ad hoc network comprising a plurality of STAs without an AP where each STA maintains a database of one-hop and two-hop STAs, and establishes a direct link to other STAs after informing neighboring STAs of an intention to establish a direct communication link.
摘要翻译：公开了一种使用直接链路建立（DLS）的对等通信系统。移动站（STA）通过向接入点（AP）（即集中式控制器）发送请求DLS的消息来建立与另一个STA的直接通信链路。 AP可以基于信道测量接受或拒绝DLS请求。如果DLS请求被接受，则建立DLS使得STA可以直接相互通信。 AP可以将建立的DLS连接拆除，其中包括向一个STA发送包括DLS拆卸请求的消息，或者基于信道测量。该系统可以是包括多个没有AP的STA的Ad hoc网络，其中每个STA维护一跳和两跳STA的数据库，并且在通知相邻STA之后建立与其他STA的直接链路，以建立直接沟通链接

摘要： The method involves sending a request frame to a responder by an initiator, and sending a response frame to the initiator without sending a separate acknowledgement (ACK) frame for acknowledging receipt of the request frame. The response frame is sent by the responder within a short inter-frame spacing (SIFS) from time that the responder receives the request frame, where the responder has a request identity number in the response frame. An independent claim is also included for a wireless communication system comprising an initiator.
摘要翻译：该方法包括由发起者向请求者发送请求帧，并且向发起者发送响应帧，而不发送用于确认接收请求帧的单独的确认（ACK）帧。应答器在响应者接收到请求帧的时间内在短帧间距（SIFS）内由响应者发送响应帧，响应者在响应帧中具有请求标识号。还包括用于包括发起者的无线通信系统的独立权利要求。

摘要： In a wireless communication system including at least one wireless transmit/receive unit (WTRU) and at least one Node-B (NB), an activation or deactivation state is determined for each of a plurality of HARQ processes. A signal that includes the activation or deactivation state for each of the HARQ processes is transmitted to the WTRU. In response to receiving the signal, the WTRU activates or deactivates a particular HARQ process in accordance with the activation or deactivation state for each of the HARQ processes contained in the received signal. The activation of HARQ processes is considered for non-scheduled transmissions.

摘要： A wireless communication method and system for controlling the current data bit rate of a radio link (RL) to maintain the quality of the RL. The system includes a core network (CN), a radio network controller (RNC) and at least one wireless transmit/receive unit (WTRU). The RL is established between the RNC and the WTRU. The RNC establishes a guaranteed data bit rate, a maximum data bit rate and a current data bit rate associated with the RL. When the RNC senses an event which indicates that the quality of the RL has substantially deteriorated, the RNC reduces the value of the current data bit rate. Then, in a recovery process, if a similar event does not occur during an established waiting period, the RNC restores the current data bit rate back to the maximum data bit rate.

摘要： A method and apparatus for selecting an antenna mapping in multiple-in/multiple-out (MIMO) enabled wireless communication networks. A candidate set of currently available antenna mappings is determined based upon measured long term channel conditions. An antenna mapping is selected from the candidate set, and the mapping is calibrated with a selected antenna mapping of a receiving wireless transmit/receive unit (WTRU). When the selected mappings are calibrated, packet data transmission begins. In an alternative embodiment, a calibration training frame (CTF) is used to calibrate multiple antenna mappings simultaneously or sequentially. Also disclosed are physical layer and medium access control layer frame formats for implementing antenna mapping selection according to the invention.

摘要： The present invention relates to a detector that detects a transmitted digital signature using the energy output from a matched filter. The energies are tabulated according to an anticipated signature pattern for variable transmission distances. The tabulation accounts for expected round trip transmission delays and allows processing of the accumulated symbols to derive a correct signature whether coherent or non-coherent signature coding is used and multiple Doppler channels are present.
