中文摘要：

由于单身的搬运人频率分割的限制，多重存取(SC-FDMA ) 在长期的进化(LTE ) 采用了 uplink，分配挑选用户设备(UE ) 的副载波一定是连续的。这连续分配限制限制资源分配灵活性并且使安排问题的资源更复杂。大多数存在工作不能很好遇见 UE 服务(QoS ) 的质量要求，因为他们就试着主要基于隧道状况或缓冲区改进系统性能，缩放。当分配频率资源时，这份报纸建议就隧道状况，缓冲区尺寸和包延期而言安排计划的一个新奇资源。第一，优化功能被提出，它试图最小化重量的和因为仍然在 UE 留下的小点在每安排的槽以后缓冲。QoS 是这里的主要担心因素。然后，推迟信息得到包，这份报纸建议一个延期评价算法。继电器节点(RN ) 被介绍改进全面隧道状况。特定的 RN 选择策略也在计划被描绘。所有最重要，有创造性的协商机制在副载波分配过程被包括。它能在用户的 QoS 要求的保证改进全面系统产量性能。模拟结果证明计划罐头极大地提高象延期，产量和神经质一样的系统性能。

英文摘要：

Due to the constraint of single carrier frequency division multiple access （SC-FDMA） adopted in long term evolution （LTE） uplink, subcarriers allocated to single user equipment （UE） must be contiguous. This contiguous allocation constraint limits resource allocation flexibility and makes the resource scheduling problem more complex. Most of the existing work cannot well meet UE＇s quality of service （QoS） requirement, because they just try to improve system performance mainly based on channel condition or buffer size. This paper proposes a novel resource scheduling scheme considering channel condition, buffer size and packet delay when allocating frequency resource. Firstly, optimization function is formulated, which aims to minimize sum of weight for bits still left in UE buffer after each scheduling slot. QoS is the main concern factor here. Then, to get packet delay information, this paper proposes a delay estimation algorithm. Relay node （RN） is introduced to improve overall channel condition. Specific RN selection strategy is also depicted in the scheme. Most important of all, a creative negotiation mechanism is included in the subcarrier allocation process. It can improve the overall system throughput performance in guarantee of user＇s QoS requirement. Simulation results demonstrate that the scheme can greatly enhance system performance like delay, throughput and jitter.
