Abstract:
Device-to-Device (D2D) communication underlaying cellular network, introduced in
LTE-Advance, is a very promising feature. Using this feature user equipments (UEs)
can communicate directly where in traditional cellular communication, all UEs need to
communicate via base station. UEs in close proximity can act as D2D pair and communi-
cate reusing the Resource Blocks (RBs) of existing cellular network infrastructure. This
D2D communication is supervised by eNodeB (Base station in LTE) and the supervising
eNodeB is also responsible for the allocation of RBs for the D2D pairs.
This thesis is concerned with the resource allocation algorithm aiming di erent goals like
maximize the total system capacity, minimizing total interference etc. These resource
allocation algorithm will be used by the supervising eNodeB to allocate appropriate RBs
to the D2D pairs (shared with existing cellular UE) to attain the goals satisfying certain
quality of service (QoS) requirements.
There are three approaches depending on the degree of sharing namely \One to One
Sharing", \One to Many Sharing" and \Many to Many Sharing" approaches for \max-
imization of sum rate" and each of the existing algorithms follows one of these. This
thesis book proposes algorithm for each of the approaches and shows the comparison
analysis. Among these, algorithm for \One to One Sharing" and \One to Many Sharing"
approaches is optimal which is theoretically proved.
