CHANNEL CONFIGURATION FOR DUAL CONNECTIVITY AND SIMULTANEOUS UPLINK TRANSMISSION

摘要

Power management is coordinated between first and second radio access nodes for channels of a first group to enable simultaneous uplink transmissions by a user equipment (UE) on first-group channels to both those nodes. This is done by, for each of the first-group channels, offsetting downward a maximum uplink transmit power on the respective first-group channel to be transmitted to one of those nodes by an amount reserved for the respective first-group channel to be transmitted to the other node. Uplink transmission opportunities (TX-OPs) of the UE on second-group channels are time-division duplexed (TDD) such that none of the UE's TX-OPs to the first access node for any second-group channel overlaps in time with the UE's TX-OPs to the second access node for the corresponding second-group channel. The network informs the UE via wireless signaling of patterns defining the TDD of the uplink TX-OPs for the second-group channels.
