Abstract
The use of LTE-Unlicensed is a promising approach to aggregate both licensed and unlicensed spectrum bands, in an effort to meet the QoS of emerging wireless services. In this chapter, we investigate the problem of carrier aggregation between licensed and unlicensed spectrum by deploying LTE-Unlicensed enabled micro-cell base stations, which have access to the unlicensed spectrum, to provide cellular users a more reliable and efficient transmission. We address the unlicensed resource allocation problem by modeling it as a student-project allocation matching game. In addition, a post-matching procedure of resource re-allocation is introduced to guarantee unlicensed users’ QoS, as well as the system-wide stability. The simulation evaluation shows the effectiveness and efficiency of our investigated matching-based approach.

- 1.
In the rest of this chapter, we abbrevate the LTE Unlicensed as LTE-U.
- 2.
The external effect in this work refers to inter-dependence of players’ preferences, more details are provided in Sect. 7.4.2.
- 3.
In this work, we assume that the UL resources of the unlicensed spectrum are shared by the CUs.
- 4.
Here the performance decrease does not refer to the interference between co-existing CUs, since the resource allocation is scheduled by the BSs. But due to the increase of CUs, each CU will be allocated less resource consequently.
- 5.
To measure CUs’ effect on VUs, we deploy sensors around U-APs to detect CUs’ interferences.
- 6.
In this work, we assume the LTE-U BSs adopt TDMA for CUs who are sharing the same unlicensed subband, and we assume equal share of time for each CU.
