Embodiment Construction

[0150] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0151] Such as Figure 1 to Figure 5 As shown, a D2D link selection scheme for integrating social information in a multi-cell scenario of the present invention includes the following steps:

[0152] Step 1: For a figure 1 In the multi-cell cellular network shown in (a), there are cellular users and D2D pairs in each cell, and there will be cross-region D2D pairs in two adjacent cells, such as the cell between cell 1 and cell 2. Cross-regional D2D to d 12 , the inter-area D2D pair d existing between cell 3 and cell 4 34 , the D2D pair can multiplex the link of the cellular user for communication. For cross-region D2D pair d 12 In terms of d 12 The two users of are located in two adjacent cells, namely cell 1 and cell 2. At this time, for d 12 The link selection of d only involves the interaction between the cell 1 and cell 2 base stat...

Abstract

The present invention discloses a D2D (Device-to-Device) link selection method of social information fusion in multi-cell scenes. The method comprises the following steps: the step 1: performing degeneration of multi-cell D2D communication scenes into D2D communication scenes for coexistence of two cells of origin for researching, performing classification of users through a base station according to the user position distribution in a network to allow the users to perform interference distinguishing; the step 2: employing an alliance having untransferable effectiveness to form a game to perform link selection for an in-cell D2D pair of the same cell where two users are located; and the step 3: performing link selection of cross-cell D2D pairs of two cells where two users are located, and considering the equalization of the cross-cell D2D pairs for the link resource usage of the two cells in the link selection process. The link selection method is simple to realize and small in signaling cost, and can ensure the equalization of the cross-cell D2D pairs for the link resource usage of two cells.

Description

technical field [0001] The present invention relates to a D2D link selection scheme for fusing social information in a multi-cell scenario. Specifically, for a cellular network where multiple cells coexist, consider intra-area D2D pairs (two users performing D2D communication are in the same cell) and cross-area D2D pairs (two users performing D2D communication are located in the same cell). A link selection method when two cells) multiplex cellular user links. Background technique [0002] In the next-generation cellular network, mobile data traffic is rapidly increasing, and service content tends to be diversified. In order to alleviate the pressure on the base station and make full use of the large number of widely distributed mobile smart terminals in the network, D2D (Device-to-Device) communication has attracted more and more attention. D2D communication allows end users with close distances to communicate directly without going through the transfer of the base stati...
