摘要： The present invention discloses a method of requesting resource from a resource allocating apparatus by a request requesting apparatus, a resource allocating apparatus, a resource requesting apparatus and a communication system. The method comprises the following steps: sending a resource request message from the resource requesting apparatus to the resource allocating apparatus; after receiving the resource request message, if resource cannot be allocated within a set time interval with respect to the resource requesting apparatus, sending an acknowledgement for the resource request message from the resource allocating apparatus to the resource requesting apparatus; and if the resource is allocated to the resource requesting apparatus within the set time interval, not sending the acknowledgement for the resource request message from the resource allocating apparatus to the resource requesting apparatus. Utilizing the method and structure of the present invention, the resource allocating apparatus sends additional acknowledgement message only if needed, therefore overhead is reduced much more. Moreover, since the solution of the present invention does not change any signaling exchanged between the resource allocating apparatus and the resource requesting apparatus, it is able to meet the requirement of backward compatibility.

摘要： A relay method and device, wherein the control signal and the data signal which are in the same subframe are directly sent to a lower level device respectively by an upper level device and a relay function device. In one example, the relay function device transmits data signal using subscriber special reference signal to make the lower level device estimate an access channel correctly; in another example, the relay function device carries out precoding of the data signal correlative with the access channel so as to cancel the influence of the access channel, thereby make the lower level device receive data signal correctly. Retransmission control signaling is sent to the lower level device in each subframe by the upper level device to ensure the fixed sequential relationship of feedback retransmission.

摘要： The present invention provides a network access method and system for Machine Type Communications (MTC), wherein the method comprises the following steps: an MTC device sends a preamble to a base station; the base station sends a Random Access Response (RAR) to the MTC device; if the RAR does not contain a temporary access resource assignment indication, the MTC device sends a Layer 2/Layer 3 message to the base station; otherwise, the MTC device re-attempts to perform network access; the base station sends a contention resolution message to the MTC device; if the contention resolution message contains a self-identification contained in the Layer 2/Layer 3 message sent by the MTC device, the network access is completed; if the contention resolution message contains the temporary access resource assignment indication, the MTC device re-attempts to perform the network access; otherwise, the MTC device attempts to perform the network access using the originally used access resource again. According to the present invention, it is enabled to dynamically and quickly perform assignment and release of MTC access resources based on actual access resource collisions, which thereby avoids waste of uplink resources in a semi-static configuration, reduces the possibility of collision, and protects normal access of non-MTC devices.
摘要翻译：本发明提供了一种用于机器类型通信（MTC）的网络接入方法和系统，其中所述方法包括以下步骤：MTC设备向基站发送前同步码; 基站向MTC设备发送随机接入响应（RAR）; 如果RAR不包含临时接入资源分配指示，则MTC设备向基站发送第2层/第3层消息; 否则，MTC设备重新尝试执行网络接入; 基站向MTC设备发送争用解决消息; 如果争用解决消息包含由MTC设备发送的第2层/第3层消息中包含的自身标识，则完成网络访问; 如果竞争解决消息包含临时接入资源分配指示，则MTC设备重新尝试执行网络接入; 否则，MTC设备尝试再次使用最初使用的接入资源执行网络接入。根据本发明，能够基于实际的接入资源冲突来动态地并且快速地执行MTC接入资源的分配和释放，从而避免了在半静态配置中浪费上行链路资源，减少了冲突的可能性，并且保护非MTC设备的正常访问。
