Problems solved by technology

While the UE is accessing the SCC, the base station cannot adjust the transmit power of the UE in the SCC through the above operations.
Therefore, if the UE accesses in a scenario where the mid-to-far point has a high noise floor, when the uplink service initiated by the terminal satisfies the activation of the SCC by the base station, the transmit power of the UE in the SCC increases very slowly, which cannot bring rapid traffic gain, resulting in user low perception

Embodiment 1

[0040] This embodiment provides a method for controlling uplink transmission power, such as figure 1 As shown, the method includes the following steps:

[0041] Step 101. Obtain the current power headroom value of the target component carrier;

[0042] Step 102: When it is determined that the target component carrier has a power headroom according to the current power headroom value of the target component carrier, send format 0 downlink control information to the terminal, and the format 0 downlink control information carries the setting a predetermined transmit power control command, and the set transmit power control command is used to increase the transmit power of the target component carrier.

[0043] In this embodiment, it is taken that the target component carrier is an SCC as an example.

[0044] In an optional embodiment, the acquiring the current power headroom value of the target component carrier includes: the base station receives the extended PHR reported by the...

Embodiment 2

[0087] This embodiment provides an uplink transmission power control device, such as image 3 As shown, the uplink transmit power control device includes: at least one processor 210 and a memory 211 for storing computer programs that can run on the processor 210; wherein, image 3 The processor 210 shown in the figure is not used to indicate that the number of processors is one, but only used to indicate the positional relationship of the processor relative to other devices. In practical applications, the number of processors can be one or more a; similarly, image 3 The memory 211 shown in FIG. 2 also has the same meaning, that is, it is only used to refer to the positional relationship of the memory relative to other devices. In practical applications, the number of memory may be one or more.

[0088] Wherein, when the processor 210 is used to run the computer program, the following steps are performed:

[0089] Obtain the current power headroom value of the target compone...

Embodiment 3

[0133] The following uses a specific example to further describe this embodiment in detail. The uplink transmission power control method provided by this embodiment is applied to LTE eNB, and the LTE eNB system is implemented on a multi-core central processor; wherein, the uplink power control adopts an accumulative method, as In an exemplary specific embodiment, P 0_PUSCH is set to -80dBm, α is set to 0.9, and θp is configured to 2. Such as Figure 4 As shown, the following only uses the first uplink scheduling, that is, the base station determines the current power headroom value of the target component carrier according to the extended PHR reported by the terminal after receiving the ActMACCE message for the target component carrier, and according to the extended PHR. The process of controlling the transmit power of the target component carrier by the current power headroom value for the first time is described as an example. The uplink transmit power control method provide...

Abstract

The embodiment of the present invention discloses an uplink transmission power control method, including: obtaining the current power headroom value of the target component carrier; determining when the target component carrier has a power headroom according to the current power headroom value of the target component carrier , delivering format 0 downlink control information to the terminal, where the format 0 downlink control information carries a set transmit power control command, and the set transmit power control command is used to increase the transmit power of the target component carrier. At the same time, the embodiment of the invention also discloses an uplink transmission power control device and a computer storage medium.

Description

technical field [0001] The present invention relates to the communication field, in particular to an uplink transmission power control method, device and computer storage medium. Background technique [0002] In the subsequent evolution of the long-term evolution (LTE-A, Long Term Evolution Advance) system, in order to meet the requirements of single-user peak rate and system capacity improvement, the carrier aggregation (CA, CarrierAggregation) technology is usually used to increase the system transmission bandwidth. Especially in the Long Term Evolution Time Division Duplexing (LTE TDD, LTE Time Division Duplexing) system, due to the small proportion of uplink subframes, the uplink rate is a bottleneck, and the demand for CA technology is even more urgent. [0003] In uplink carrier aggregation (ULCA, Uplink Carrier Aggregation), the cell accessed by the terminal is the primary carrier (PCC, Primary Component Carrier), and the secondary carrier (SCC, Secondary Component Ca...
