摘要： In a relay based wireless communication system, a method for transmitting an uplink backhaul sub-frame of a relay node includes obtaining scheduling information for an uplink backhaul sub-frame through a downlink backhaul control channel from a base station, and performing a rate matching and mapping of data by regarding at least one predefined symbol as a blank symbol. The predefined symbol is located at a front part or a rear part of the scheduled uplink backhaul sub-frame. The transmitting method further includes performing a multiplexing of the uplink backhaul sub-frame, and transmitting the multiplexed uplink backhaul sub-frame. This method can eliminate an overlap of transmission and reception timing in a relay node due to an RF transmission/reception switching time delay. Also, the method can make better use of wireless backhaul resources and minimize an influence on conventional systems by offering the compatibility with conventional uplink and downlink sub-frame structures.
摘要翻译：在基于中继的无线通信系统中，用于发送中继节点的上行链路回程子帧的方法包括通过来自基站的下行链路回程控制信道获取上行链路回程子帧的调度信息，并且执行速率匹配，通过将至少一个预定义符号作为空白符号进行映射。预定义符号位于调度的上行回程子帧的前部或后部。发送方法还包括执行上行链路回程子帧的复用，以及发送多路复用的上行回程子帧。由于RF发送/接收切换时间延迟，该方法可以消除中继节点中的发送和接收定时的重叠。此外，该方法可以通过提供与常规上行链路和下行链路子帧结构的兼容性，更好地利用无线回程资源并最小化对传统系统的影响。

摘要： The objective of the present invention is to control the HARQ process for two codewords assigned to each UE in downlink of the LTE-A system efficiently. In the proposed method, particularly when one of the two codewords is decoded successfully but the other is not in the HARQ process, the UE can be scheduled for both the retransmission and initial transmission by means of the control signal of PDCCH or ACK/NACK information of PHICHs. The proposed method is capable of reducing resource amount necessary for the control signal transmission without increasing the PDCCH decoding complexity of the UE.

The method for transmitting a backhaul sub frame channel according to one embodiment of the present invention comprises: creating a downlink relay control channel by coding downlink relay control information that is transmitted to a relay; allocating the created downlink relay control channel to a first slot of a semi-static resource region that is allocated to the relay; and transmitting, to the relay, a backhaul sub frame to which the channel is allocated. Compared to existing control channel transmission techniques, the present invention can minimize overheads. Moreover, the present invention also reduces control channel resources required during retransmission and for the transmission of multiple backhaul subframes.

摘要： The present invention relates to a fractional RB (Resource Block) allocation method which enables resource allocation in a unit smaller than RB to improve the capacity of VoIP (Voice over Internet Protocol) in an LTE (Long Term Evolution) system. That is, the present invention introduces a resource arrangement method which allows different users to share the same resource, without even using an SDMA, and a method for informing the fractional RB allocation and how to use the same. A method for introducing multiplexation into an RB and changing the RE arrangement is proposed to support the downlink fractional RB allocation. A method for changing the RE arrangement is also proposed to support the uplink fractional RB allocation. According to the present invention, to provide a consistent service with a small amount of traffic generated as in the VoIP, resources of a smaller amount than a single RB can be used for a terminal with a good channel state. In the present invention, the occupancy of resources for the terminals of an excellent channel state is reduced so that the capacity of the VoIP can be improved.
摘要翻译：本发明涉及一种分数RB（资源块）分配方法，其能够以比RB小的单元进行资源分配，以提高LTE（长期演进）系统中的VoIP（因特网协议语音）的容量。也就是说，本发明引入了一种资源安排方法，其允许不同的用户共享相同的资源，甚至不使用SDMA，以及用于通知分数RB分配的方法以及如何使用它们。提出了一种将多路复用引入RB并改变RE布置的方法，以支持下行分数RB分配。还提出了用于改变RE布置的方法以支持上行分数RB分配。根据本发明，为了提供与VoIP中生成的少量流量一致的服务，具有比单个RB更小的资源的资源可以用于具有良好信道状态的终端。在本发明中，降低了优良信道状态的终端的占用资源，能够提高VoIP的容量。
