Description

Uplink transmission power configuration method, device, equipment and storage medium

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for configuring uplink transmit power of a user equipment.

Background

With the development of mobile communication technology, in order to meet the requirement of higher transmission rate, high frequency, large bandwidth, large-scale antenna technology and multi-carrier aggregation are increasingly the trend of wireless communication technology development.

The multi-carrier aggregation technique is also widely used in fifth-generation communication systems, and is mainly classified into carrier aggregation between frequency bands of 6GHz or less, carrier aggregation between millimeter-wave frequency bands, and carrier aggregation between a frequency band of 6GHz or less and a millimeter-wave frequency band. The radio frequency architecture of carrier aggregation between frequency bands below 6GHz follows the radio frequency architecture of LTE, the radio frequency front ends of the frequency bands need to be connected through various radio frequency passive devices for sharing an antenna system, and these devices introduce some extra insertion loss, so that extra wide capacitance values need to be introduced in uplink and downlink respectively on radio frequency indexes, and once the architecture is determined, no matter whether carrier aggregation is scheduled on multiple carriers simultaneously, loss always exists. The carrier aggregation between millimeter wave frequency bands, particularly the carrier aggregation based on independent beam management, uses independent radio frequency paths and antenna arrays respectively, and can cause the transmission power to introduce a certain wide-capacity value for the problems of mutual interference between two paths or multiple paths of radio frequency power amplifiers or power consumption heating and the like of an uplink path. Since the above-mentioned interference or power consumption heating problem does not exist when the Secondary cell (Scell) is deactivated or deleted, the uplink coverage of the Primary cell (Pcell) cannot be improved even when the Secondary cell is deactivated.

The method comprises the following steps:

receiving configuration information and acquiring state information of a serving cell of user equipment; the configuration information is used for configuring uplink transmitting power, the serving cell comprises at least one activated serving cell, and the state information at least comprises information used for indicating that the state of a secondary cell of the user equipment changes;

In an embodiment, the state information includes information indicating that the state of the primary cell is an active state and that the state of the secondary cell changes.

In an embodiment, the configuration information includes both configuration information for indicating the uplink transmission power of the initial configuration of the user equipment corresponding to the primary cell and configuration information for indicating the uplink transmission power of the initial configuration of the user equipment corresponding to the secondary cell.

In this embodiment, the uplink transmission power can be determined based on the configuration information corresponding to each serving cell.

The embodiment of the present disclosure provides a method for configuring uplink transmit power of user equipment in a multi-carrier system, which is performed by the user equipment; the method may be performed independently or in conjunction with any of the other embodiments of the disclosed embodiments. Fig. 2 is a flowchart illustrating an uplink transmit power configuration method according to an exemplary embodiment, where as shown in fig. 2, the method includes:

In one embodiment, the first value represents a first wide-tolerance value. The wide-tolerance value is introduced to overcome the performance degradation caused by each path in the uplink path for supporting multiple operating frequency bands. In the case where the secondary cell is changed from the activated state to the deactivated state or the secondary cell is deleted, the first value, that is, the first tolerance value may be a smaller value, or the first tolerance value may also be zero. The first value is generally smaller than a wide-tolerance value used when determining uplink transmission power corresponding to the primary cell when the primary cell is in an active state and the secondary cell is also in the active state. Since the main cell is in the active state and the auxiliary cell is also in the active state, there are problems of mutual interference or power consumption heating between two or more radio frequency power amplifiers and/or performance degradation caused by that each path in the uplink path supports multiple operating frequency bands, and the like, the tolerance value in this case is usually a large value.

In this embodiment, when the state of the secondary cell changes, that is, the state of the secondary cell changes from the active state to the deactivated state or the secondary cell is deleted, the uplink transmission power corresponding to the primary cell is determined using a smaller wide-tolerance value, so that the uplink transmission power of the primary cell is increased, thereby improving the uplink coverage of the primary cell.

At this time, the uplink transmission power corresponding to the primary cell is still determined by using the second value, i.e. the second wide tolerance value. In one embodiment, the second value is greater than the first value.
