Technical Field

Background
In a mobile communication system, in order to improve system throughput, a Dual Connectivity (DC) technology is introduced to support a User Equipment (UE) in a Radio Resource Control (RRC) connection state to simultaneously use Radio resources provided by two base stations, and the two base stations may be connected through non-ideal transmission.
As shown in fig. 1, in a communication system using dual connectivity technology, a UE is simultaneously connected to a Master base station (hereinafter, referred to as Master eNodeB for short, MeNB) and an auxiliary base station (hereinafter, referred to as Secondary eNodeB for short, SeNB); wherein the primary base station is responsible for providing an interface with the core network and providing a mobility anchor function to the core network, and the secondary base station is responsible for providing additional radio resources to the UE. In order to ensure the effectiveness of connection between the UE and two base stations, in a dual-connection system, a main base station semi-statically allocates main base station protection power and auxiliary base station protection power to the UE, and in an uplink data transmission process, the transmission power allocated to the main base station and the auxiliary base station by the UE cannot exceed the respective protection power. Because the UE establishes communication connections with the primary base station and the secondary base station at the same time, that is, the UE uses two uplinks for data transmission (the two uplinks are respectively the uplink established by the UE and the primary base station and the uplink established by the UE and the secondary base station), when the UE transmits service data, the UE always needs to establish communication connections with the primary base station and the secondary base station, which causes the increase of power consumption of the UE and further reduces the standby time of the UE.
As can be seen from the above, in the communication system adopting the dual connectivity technology in the prior art, when the UE transmits service data, it is always necessary to establish communication connection with the primary base station and the secondary base station, which causes an increase in power consumption of the UE, and further reduces the standby time of the UE.

S102, the UE acquires uplink power control parameters when determining that the main base station and the auxiliary base station are accessed simultaneously according to the system information.
It should be noted that, in practical applications, when a UE in a communication system adopting the dual connectivity technology simultaneously accesses a primary base station and a secondary base station, the UE and the primary base station establish an uplink (for convenience, collectively referred to as a first uplink), and the UE and the secondary base station establish an uplink (for convenience, collectively referred to as a second uplink), so that the primary base station and the secondary base station can simultaneously receive uplink data of a predetermined service transmitted by the UE; however, when the UE establishes a connection with the primary base station and the secondary base station simultaneously for a long period of time, power consumption of the UE may increase. As shown in fig. 3, when the UE transmits uplink data of a predetermined service, it needs to pass through a plurality of power control periods T; therefore, in the data transmission method provided by the embodiment of the present invention, the power control period T is divided into the power control initial period T0And a power control adjustment period T1When the uplink data of the predetermined service sent by the UE is in the power control initial period T of the power control period T0Meanwhile, receiving the uplink data of the preset service through the main base station and the auxiliary base station; and when the uplink data of the predetermined service sent by the UE is in the power control regulation period T of the power control period T1When the uplink data of the predetermined service is received only by the anchor base station (the main base station or the auxiliary base station), namely, the UE transmits the uplink data of the predetermined service through the uplink established with the main base station or the uplink established with the auxiliary base station, and the uplink established between the non-anchor base station and the UE is closed, thereby reducing the uplink of the predetermined service and the uplink of the UEThe UE consumes power.
Specifically, the uplink power control parameter T, T0、T1Can be configured in advance at the UE side or the base station side; if the configuration is at the UE side, the UE may query the uplink power control parameter pre-configured in the database when determining to access the main base station and the auxiliary base station simultaneously and when acquiring the uplink power control parameter.

It should be noted that the power control initial period T0Is provided withWhen the sum of the transmission capacities of the first uplink and the second uplink is too small, the uplink throughput rate and the uplink transmission delay statistical period of the first uplink and the uplink throughput rate and the uplink transmission delay statistical period of the second uplink are also reduced, and at this time, the uplink throughput rate and the uplink transmission delay statistical value of the first uplink and the uplink throughput rate and the uplink transmission delay statistical value of the second uplink may be affected by wireless environment fluctuation such as channel fast fading and the like, so that the transmission capacities of the first uplink and/or the second uplink cannot be accurately reflected; therefore, the user can set T, T the uplink power control parameter by himself according to the actual situation0、T1The value of (a).
Specifically, the initial transmission power P0The determination method comprises the following steps: the UE determines the currently available power headroom (i.e., the remaining transmit power), the initial transmit power P0Is one half of the currently available power headroom of the UE; wherein the currently available power headroom of the UE is equal to the difference between the maximum transmit power of the UE and the power already consumed by the currently ongoing uplink transmission.
