Description

Power control method and device based on uplink multi-carrier simultaneous transmission
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a power control method and apparatus based on uplink multi-carrier simultaneous transmission.
Background
With the standardization of new air interfaces (NR) in the future, the fifth generation mobile communication technology will gradually enter into practical use. Due to the widespread deployment of the fourth generation Long Term Evolution (LTE), a large amount of low frequency spectrum has been divided for LTE use. Future networks and terminals supporting fifth generation mobile communication technologies will face shared spectrum usage with LTE systems.
When spectrum usage shared by LTE and NR is performed, one method is to share the LTE uplink spectrum and NR, that is, the LTE uplink spectrum may transmit LTE and NR signals at the same time. The advantage of this approach is that the NR uplink coverage and data transmission can be enhanced with partial LTE uplink resources.
For a terminal, according to the terminal capability, there are two ways of supporting shared NR carrier and LTE carrier uplink transmission, one is that only one of the two carriers can be selected for transmission at a time point, and the other is that one time point can support simultaneous transmission on the two carriers.
Terminals that can only transmit on one carrier for a point in time need only maintain separate power control systems on different carriers. For a terminal supporting simultaneous transmission of an NR carrier and an LTE carrier, two sets of parallel power control devices need to be considered.
The adoption of two sets of parallel power control firstly needs to solve the power distribution problem of two sets of power control systems. Due to the maximum transmission power limitation of the terminal, even if two carriers use independent radio frequency transmission devices, a total maximum transmission power limitation is still observed on the maximum transmission power, rather than simply observing the maximum transmission power limitations of the respective carriers. The constraint imposed by this limitation is that at any one time, the mechanism of power allocation and the maximum power allocation limitation problem need to be considered.
In addition, for NR, uplink data transmission based on a non-scheduling scheme is supported, and when data transmission based on non-scheduling is performed, if data transmission is performed on LTE and NR shared carriers, orthogonality between LTE and NR transmission may be destroyed, thereby causing extra interference.

Suppose PNCIndicating the control channel transmission power, P, on the NR carrierNDIndicating the data channel transmit power on the NR carrier. For non-scheduled uplink data transmission, the transmission power is PGF. In order to ensure orthogonality of data transmission on an LTE carrier, non-scheduling-based uplink data transmission is limited to be transmitted only on an NR carrier.

But limited by the maximum transmission power of the terminal, the sum of the powers of all channels cannot exceed the maximum allowed transmission power Pmax of the terminal. Therefore, after each channel determines the power to be transmitted, it is necessary to update the available transmission power of each channel according to the power limit.

In determining Pmax- (P)GF+PLC+PNC)-(PLD+PND) Whether less than 0, and c × (Pmax-P)GF-PLC-PNC) Whether or not greater than PNDThen, after step 203, if there is an adjusted parameter, the power value of the corresponding adjusted parameter is used to determine: pGF、PLC、PNC。
Does not satisfy Pmax- (P) at the same timeGF+PLC+PNC)-(PLD+PND) Less than 0, and c × (Pmax-P)GF-PLC-PNC) Not more than PNDUnder both conditions, P is not adjustedNDI.e. PNDRemain unchanged.
