摘要： A method and system for allocating a particular uplink control region to both HARQ ACKCH and CQICH in order to maximize uplink bandwidth for data transfer in a communication network. A control region scheduling (CRS) utility assigns a higher priority to HARQ ACKCH relative to CQICH. When both HARQ ACKCH and CQICH are to be allocated for a subscriber in the same region in the same frame, HARQ ACKCH is allocated in the region while CQICH is rejected. As the substitute to the rejected CQICH, the CRS utility may use current uplink channel quality information in combination with the corresponding HARQ ACK transmission to estimate the downlink channel quality information for the subscriber. Upon receiving the HARQ ACK information, the CRS utility updates the subscriber(s) uplink channel quality information. The CRS utility also provides a configurable option of activating or de-activating the sharing of the uplink control region.
摘要翻译：用于向HARQ ACKCH和CQICH两者分配特定上行链路控制区域的方法和系统，以便最大化用于通信网络中的数据传输的上行链路带宽。控制区域调度（CRS）实用程序相对于CQICH向HARQ ACKCH分配更高的优先级。当HARQ ACKCH和CQICH都将在相同帧中的相同区域中的用户分配时，HARQ ACKCH被分配在该区域，而CQICH被拒绝。作为拒绝的CQICH的替代品，CRS实用程序可以使用当前的上行链路信道质量信息与相应的HARQ ACK传输相结合来估计用户的下行链路信道质量信息。在接收到HARQ ACK信息时，CRS实用程序更新订户上行链路信道质量信息。 CRS实用程序还提供了激活或取消激活上行链路控制区域共享的可配置选项。
