Problems solved by technology

However, in order to compensate for the increase in path loss in the high-frequency band or the coverage shrinkage caused by the poor signal at the location of the terminal, in the 2.6GHz, 3.5GHz and 4.9GHz frequency bands, the maximum transmit power of a higher-power terminal is defined, which is increased to 26dBm, in this case, the base station using TDD (Time Division Duplexing, time division duplex) mode, that is, TDD base station, can be realized by adjusting the uplink and downlink duty cycle, and the base station using FDD (Frequency Division Dupl

Abstract

The embodiment of the invention provides a dual-connection communication structure and an uplink method thereof, which relate to the field of communication and can satisfy the SAR (Specific AbsorptionRate) limit requirement while guaranteeing the uplink coverage. The method includes the following steps: a user terminal sends a scheduling request containing the maximum uplink transmission power toa TDD (Time Division Duplexing) base station and an FDD (Frequency Division Duplexing) base station; when the maximum uplink transmission power is determined to be greater than a preset power, the TDD base station sends a first uplink duty cycle to the FDD base station; the FDD base station sets a second uplink duty cycle according to the first uplink duty cycle to enable the average uplink transmission power of each wireless frame length in the communication connection between the two terminal and a target base station to be less than or equal to the preset power; and the TDD base station and the FDD base station respectively send a first scheduling consent permission including a first uplink slot and a second scheduling consent permission containing a second uplink slot generated thereby to the user terminal so that the user terminal can transmit uplink information to the target base station in the first uplink slot and the second uplink slot.

Description

technical field [0001] The invention relates to the communication field, in particular to a dual connection communication structure and an uplink method thereof. Background technique [0002] At present, there are two types of 5G network architecture implementation solutions, one is an independent (SA, Standalone) network structure, and the other is a non-independent network (NSA, Non-standalone) structure. Under the SA architecture, the terminal only connects to 5GNR (New Radio, new air interface) at the same time, while under the NSA architecture, the terminal will connect to 5GNR and LTE two air interfaces at the same time, that is, the terminal will connect to two types of base stations at the same time, so it is also called LTE. (Long Term Evolution, long-term evolution) and NR dual connection network. Because the terminal design needs to meet the limit requirements for human body radiation (SAR, Specific Absorption Rate, electromagnetic wave absorption ratio), when th...
