Problems solved by technology

Part of the work considered the QoS requirements of cellular users, but did not realize the joint optimization of D2D user power, cellular user power and resource block allocation under the condition of limited interference
"DownlinkResourceReuseforDevice-to-DeviceCommunicationsUnderlayingCellularNetworks" (resource reuse in D2D communication based on cellular network) [IEEESIGNAL PROCESSINGLETTERS, VOL. The QoS requirements of cellular users are met, but the interference limitation is not considered
At present, in the available data, there is still no precedent for joint resource allocation and guaranteed QoS requirements in cellular network-based D2D communication systems.

Embodiment

[0059] Examples of the present invention figure 1 As shown, a joint resource allocation method of a D2D communication system based on a cellular network is implemented by a D2D communication system based on a cellular network: the system includes two parts: a cellular system and a D2D system, and the cellular system includes a base station BS and C cellular users ; The D2D system includes L pairs of D2D users, the first pair of D2D users includes a D2D transmitter TXl and a D2D receiver RXl, where l∈{1,2,...,L}, assume that the cellular network-based D2D communication system has a total C resource blocks, each cellular user occupies a corresponding resource block, and each resource block is reused by a pair of D2D users at most, let the symbol y l,c ∈{0,1} represents the resource block reuse factor, that is, when the D2D user pair l reuses the cth resource block, y l,c = 1; when the D2D user does not reuse the cth resource block for l, y l,c = 0; then where c∈Λ represents ...

Abstract

The invention provides a method for allocating joint resources of a D2D communication system based on a cellular network, and belongs to the technical field of wireless communication. In the D2D communication system based on the cellular network, a D2D user can reuse a resource block of a cellular user (CU) to realize direct communication without relying on a base station. The resource allocation method is not only used for jointly optimizing the power allocation and resource block allocation of the D2D user and the cellular user under limit interference conditions to achieve the purpose of high energy efficiency, but also considering the QoS requirements of the cellular user, balancing the QoS requirements of the cellular user and the continuously improved D2D system and rate, and filling the blank of carrying out resource allocation and guaranteeing the QoS requirements in the D2D communication system based on the cellular network under the limit interference conditions.

Description

technical field [0001] The invention relates to a method for allocating joint resources of a D2D communication system based on a cellular network, and belongs to the technical field of wireless communication. Background technique [0002] At the 2007 World Wireless Communication Conference, the bandwidth allocated for mobile communication systems was less than 600MHz. At the same time, the bandwidth allocation below 5GHz is already very crowded. It is estimated that by 2020, the bandwidth demand for wireless communications will be between 1200MHz and 1700MHz. Bandwidth resources can no longer meet the needs of wireless communication development. To reduce the discrepancy between bandwidth supply and bandwidth demand, it becomes important to utilize the allocated bandwidth more efficiently. [0003] At the same time, a lot of work is driving the evolution of next-generation wireless communication systems, such as LTE-A and WiMAX. The future wireless cellular network will ha...
