The shared-TDD scheme has been proposed to accommodate asymmetric communications between uplink and downlink. The accommodation of connectionless services in shared-TDD systems causes a difficulty of TDD boundary control. The paper proposes a TDD boundary control (resource assignment) scheme, which can optimize the TDD boundary based on the ratio of uplink to downlink traffic in CDMA/shared-TDD systems with connectionless services. Computer simulations show that the proposed scheme effectively controls the radio resource, and thus improves total throughput performance.
