First Claim
Patent Images
1. A base station, comprising:
- an information processing module that determines a number of uplink user equipments (UEs) handled by the base station, and a number of downlink UEs handled by the base station;
a calculation module that determines a metric calculation based on the determined number of uplink UEs and the determined number of downlink UEs; and
a frame formatting module that adjusts a number of subframes within a frame based on the determined metric calculation.

Abstract
Systems and methods are directed to deciding the number of subframes in a frame to use for uplink transmission, with the remaining frames used for downlink transmission for a Base Station (BS) in a Time Division Duplexing Long Term Evolution (TDD-LTE). Systems and methods are based on the number of User Equipment (UEs) that the BS has to serve in the uplink and in the downlink, as well as the uplink (UL) and downlink (DL) traffic loads per user. Systems and methods are directed to allowing a TDD LTE BS to partition the subframes in a frame for its UL and DL traffic.
