Uplink transmission control for asymmetric communications in CDMA/shared-TDD cellular packet communications

摘要

Shared-TDD scheme has been proposed for accommodation of asymmetric communications between uplinks and downlinks. The application of Shared-TDD scheme to cellular systems causes inter-link interference. This paper proposes uplink transmission control in order to relieve effect of inter-link interference in CDMA/Shared-TDD cellular packet systems. In the proposed scheme, mobile stations select transmission slots based on their location. Computer simulation shows that the proposed scheme relieves effect of inter-link interference, and thus improves downlink transmission efficiency.
