Simultaneous transmit and receive

摘要

A simultaneous transmit and receive (STR) technology is described. The eNB is configured with a downlink centric measurement threshold and an uplink centric measurement threshold which increase overall capacity in the wireless cellular network. A signal measurement command is transmitted from the eNB to the UE instructing the UE to take a signal quality measurement. The signal quality measurement is received from the UE at the eNB. It is determined whether the signal quality measurement is greater than the downlink centric measurement threshold and whether the signal quality measurement is greater than the uplink centric measurement threshold. The downlink centric measurement threshold, the uplink centric measurement threshold, and the DL/UL ratio are configured to increase capacity in the wireless cellular network through selective use of STR.

1. A user equipment (UE) operable to perform full duplex radio communication in a wireless cellular network, having computer circuitry configured to:
receive a signal quality measurement command from an evolved node B (eNB) at the UE; measure a signal quality at the UE in response to the signal quality measurement command to form a signal quality measurement at the UE; transmit the signal quality measurement to the eNB to enable the eNB to:
identify a net network capacity gain by checking the signal quality measurement at the UE; andset a signal quality threshold based on a signal quality level that results in the net network capacity gain in order to use simultaneous transmission and reception (STR); receive a duplex communication mode command from the eNB that is based on the signal quality threshold; and operate the UE in full duplex communication mode or half-duplex communication mode as dictated by the duplex communication mode command.
