摘要： Methods and apparatuses for scheduling transmissions between a base station and multiple user stations in a broadband wireless access network may include a subscriber station generating a bandwidth request which includes one of a limited number of available and predefined preamble sequences and a data portion identifying the resources requested. The subscriber station randomly selects a contention slot in a wireless channel, allocated by the base station, for sending a bandwidth request. The receiving base station is able to detect the preamble sequence of bandwidth requests and differentiate between subscribers even when bandwidth requests of two or more subscribers may collide by virtue of selecting the same contention slot. In this manner, latency and overhead of bandwidth requests may be improved. Additional variants and embodiments are also disclosed.

摘要： In wireless communication networks that use ARQ/HARQ feedback protocols, when a first device receives an apparent HARQ ACK from a second device, the first device may make a new transmission using a HARQ Channel ID whose previous usage was under conditions indicating a likelihood of error in the ACK. When the second device receives the new transmission, the reuse of that HARQ Channel ID in a new transmission rather than a retransmission lets the second device know that its previous NAK transmission was incorrectly received as an ACK.
摘要翻译：在使用ARQ / HARQ反馈协议的无线通信网络中，当第一设备从第二设备接收到明显的HARQ ACK时，第一设备可以使用HARQ信道ID进行新的传输，其先前的使用处于表示错误的可能性的条件在ACK中。当第二设备接收到新的传输时，在新的传输中重新使用该HARQ信道ID而不是重传，使得第二设备知道其先前的NAK传输被错误地接收为ACK。
