Description

TECHNICAL FIELD The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for configuring transmit power. In the 3GPP LTE (The 3rd Generation Partnership Project Long Term Evolution) system, uplink power control (uplink power control, referred to as uplink power control or power control) is used to control the physical uplink channel. (Uplink Physical Channel) transmit power to compensate for channel loss and shadow, and to suppress inter-cell interference. The physical uplink channel controlled by the uplink power control includes a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and a sounding reference signal (SRS). LTE uplink power control uses a combination of open loop (Open Loop) and closed loop (Closed Loop) control.

In the LTE system, the transmit power (in dBm) of the PUSCH of the User Equipment (UE) on the subframe (Subframe) i is defined as: ^PUSCH (0 = min{ _CMAX , 10 log ₁₀ (M _p P _{0 PUSCH} (j) + a(j) - PL + A _W (i) + /( )} In the above formula, each parameter represents:

The LTE-Advanced system (referred to as LTE-A system) is the next-generation evolution system of the LTE system. As shown in Figure 1, the LTE-A system uses carrier aggregation technology to extend the transmission bandwidth. Each aggregated carrier is called a component carrier. Multiple component carriers can be contiguous or non-contiguous, can be in the same frequency band, or can be in different frequency bands.

In the LTE-A system, the user equipment may transmit one physical uplink shared channel PUSCH on one (uplink) component carrier, or may simultaneously transmit multiple PUSCHs on multiple (upstream) component carriers. It is also proposed that multiple physical uplink control channels can be transmitted on one (upstream) component carrier.

PUCCH, and simultaneously transmit PUSCH and PUCCH on one (uplink) component carrier. According to the transmission power configuration method of the related art, the transmission power of the PUSCH and/or the PUCCH on a single component carrier is configured, which is called the estimated transmission power of the PUSCH and the estimated transmission power of the PUCCH. Both the estimated transmit power of the PUSCH and the estimated transmit power of the PUCCH satisfy the transmit power requirements and constraints based on the component carrier. However, on subframe i, when multiple PUSCHs and/or PUCCHs on multiple component carriers are simultaneously transmitted, if the sum of the estimated transmit powers is greater than the maximum configured output power of the user equipment, the user equipment must reduce the transmit power. According to the related art transmission power configuration method, it configures only the physical uplink channel on a single component carrier, and cannot support the architecture of multiple component carriers in the LTE-A system, that is, when transmitting simultaneously on multiple component carriers When the sum of the estimated transmit powers of the multiple PUSCHs and/or the PUCCHs is greater than the maximum configured output power of the user equipment, the configuration method in the related art cannot configure the transmit power for each physical uplink channel on the plurality of component carriers. SUMMARY OF THE INVENTION The present invention has been made in view of the problem of the configuration in which the transmission power of each physical uplink channel on a component carrier cannot be performed in the related art. To this end, the main object of the present invention is to provide a method and apparatus for configuring transmission power.

The present invention has the following beneficial effects: When the sum of the estimated transmit powers of the plurality of physical uplink channels simultaneously transmitted is greater than the maximum configured output power of the user equipment, the present invention reduces the transmit power of all the physical uplink shared channels according to a certain ratio. Or set the transmit power of one or more physical uplink shared channels to 0, which can effectively reduce the transmit power of each physical uplink channel.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. 2 is a schematic diagram of a wireless communication system in accordance with an embodiment of the present invention. As shown in FIG. 2, the wireless communication system based on the embodiment of the present invention includes: a user equipment 202 and a base station 204. The embodiment of the present invention mainly improves the method for configuring the transmit power of the physical uplink channel on the user equipment 202, which will be described below with reference to the accompanying drawings. FIG. 3 is a flowchart of a method for configuring transmit power according to an embodiment of the present invention. As shown in FIG. 3, the method for configuring the transmit power may include the following steps:

S302. Calculate a power parameter of each physical uplink shared channel PUSCH.

S308. Determine whether a sum of the estimated transmit power of the PUSCH and the estimated transmit power of the physical uplink control channel PUCCH that is not set to 0 is greater than a maximum configured output power of the user equipment.

S310. If not greater, set a transmit power of a PUSCH whose transmit power is not set to 0 to an estimated transmit power of the PUSCH. According to the related art transmission power configuration method, it is configured only for a physical uplink channel on a single component carrier, and cannot perform transmission power configuration for a plurality of physical uplink channels on a plurality of component carriers. In contrast, embodiments of the present invention, when multiple PUSCHs are simultaneously transmitted on multiple component carriers

When the sum of the estimated transmit powers of the PUCCH is greater than the maximum configured output power of the user equipment, the transmit power of all the physical uplink shared channels is reduced according to a certain ratio or the transmit power of one or more physical uplink shared channels is set. 0, this can effectively reduce the transmit power of each physical uplink channel. The user equipment may only transmit the PUSCH on the subframe i, or only transmit the PUCCH, or simultaneously transmit the PUSCH and the PUCCH. The PUCCH is only transmitted on a specific component carrier, and its estimated transmit power satisfies the requirements and constraints of the component carrier based transmit power.
