Abstract:
1. An apparatus for allocating resources during call setup based on whether or not downlink transmit delay diversity (TDD) is needed for the call being setup, the apparatus comprising: first logic configured to evaluate one or more downlink parameters associated with a call; second logic configured to determine whether or not TDD is needed for the call based on the evaluation by the first logic; third logic configured to allocate a duplex transceiver to the call if the second logic makes a determination that downlink TDD is needed, the duplex transceiver being configured to implement downlink TDD, and comprising at least two simplex transceivers, each simplex transceiver being connected to a respective antenna, said at least two simplex transceivers communicating with a single mobile device during a single time slot; fourth logic configured to allocate a simplex transceiver to the call if the second logic determines that downlink TDD is not needed for the call, the simplex transceiver not being configured to implement downlink TDD; and fifth logic configured to evaluate the downlink parameters while the call is in progress and initiate a handover from the simplex transceiver to the duplex transceiver if the logic determines that downlink TDD is needed or initiate a handover from the duplex transceiver to the simplex transceiver if the logic determines that downlink TDD is no longer needed.
