Systems and methodologies are described that facilitate providing relay nodes in wireless networks. In particular, cluster nodes, which can be regular eNBs, can provide wireless network access to the relay nodes over a backhaul link, and the relay nodes can offer access to devices or other relay nodes to expand network coverage and / or provide increased throughput. User equipment (UE) relays can function as UEs according to a cluster node such that UE relays receive network addressing and can tunnel communications through the cluster node using the backhaul link. Cell relays can function as a cell of the cluster node, such that transport layer communications terminate at the cluster node. In this regard, cell relays can define transport layers to use in communicating with the cluster nodes over the backhaul and with other devices over a provided access link.

The invention aims at providing a multi-cell relay OFDM system resource distribution method with frequency planning. The multi-cell relay OFDM system resource distribution method with the frequency planning is low in complexity. Maximum system capacity serves as the goal of the multi-cell relay OFDM system resource distribution method, the frequency planning is applied, and a model is built under the condition that base stations and relay terminals are limited in transmitted power. The multi-cell relay OFDM system resource distribution method with the frequency planning comprises the following steps that a single cell is divided into three independent regions, different frequency bands are used for different regions, users in the different regions access to relays which are shortest in distance, therefore, distances of the users using the same frequency band between adjacent cells are increased, and then the influence of co-channel interference can be reduced; through self-adaptive distribution of the transmitted power of base station terminals of different regions, eventually system total capacity is decoupled to the sum of capacities of the three regions, and algorithm complexity is reduced; power of the base station terminals is used for representing power of the relay terminals according to DF relay features in the process of analyzing the resource distribution problems of a single region, therefore, an optimization problem in a standard form is converted, and eventually a final solution of the problem is acquired by utilizing multiple plane water injection and loop iteration theories.

Systems and methods are described herein that facilitate mapping of multiple Evolved Packet System (EPS) bearers to a single relay eNB radio bearer. In particular, the upstream eNB may select the radio bearer of the downstream eNB for association to the EPS bearer based on best effort matching or essentially any logic. The upstream eNB may store the association between the radio bearer and the EPS bearer for subsequent downstream packet routing. The upstream eNB may also provide an indication of the selected radio bearer to the downstream relay eNB to facilitate packet routing from upstream. Alternatively, the upstream eNB may also select the radio bearer of the downstream eNB for associating with the EPS bearer according to the Quality of Service (QoS) Class Identifier (QCI) of the EPS bearer.

Priority cell relay method and communication realize system belong to network transmission technology with definite cell legnth. Cells are designed in different cell transmission priorities according to the special information carried by each cell generated and sent by the source cell send terminal. The network terminal at the network entrance monitors the cell arriving speed of dummy connection and discards priority of the cell arrived at the cell device.

The present invention provides a cell relay handover method and system. The method includes: judging whether the terminal is in a high-speed mobile state according to the measurement report reported by the terminal, and if so, allocating high-speed air interface resources for the terminal. The high-speed air interface resources are Refers to the physical channel resources allocated for high-speed mobile terminals; according to the measurement report reported by the terminal, determine the target cell for handover, instruct the target cell to enable the high-speed air interface resource, and monitor the signal of the high-speed air interface resource; The measurement report judges whether the bit error rate of the target cell on the high-speed air interface resource is less than a preset bit error rate, and if it is smaller, releases the wireless link of the current cell, and switches the terminal to the target cell middle. By controlling the handover process, the cells allocate high-speed air interface resources to the terminals in the high-speed mobile state, so that the terminals always run on the same physical channel resource, and realize the relay handover between the cells.
