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.

In one embodiment, when the primary cell is in an activated state, the secondary cell is changed from the activated state to a deactivated state, or the secondary cell is deleted, the problem of heating of an uplink due to mutual interference or power consumption between two or more radio frequency power amplifiers does not exist, and at this time, a smaller wide-tolerance value is subtracted from the configuration information to determine the uplink transmitting power corresponding to the primary cell.

In one embodiment, the status information is indicated by at least one of a MAC CE and DCI.

In one embodiment, the primary cell is in an activated state, the secondary cell is changed from an activated state to a deactivated state, or the secondary cell is deleted. 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 status information is indicated by at least one of a MAC CE and DCI.

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. 8 is a flowchart illustrating an uplink transmit power configuration method according to an exemplary embodiment, where as shown in fig. 8, the method includes:

step 801, receiving configuration information, and acquiring state information of a serving cell of user equipment; the configuration information is used for indicating the uplink transmitting power of initial configuration, and the service cell comprises at least one activated service cell;

step 802, in response to the state information including that the primary cell is in an activated state and the secondary cell is changed from a deactivated state to an activated state, and receiving updated configuration information, determining that the uplink transmission power corresponding to the primary cell is a difference between the updated configuration information and the second value, and determining that the uplink transmission power corresponding to the secondary cell is a difference between the configuration information corresponding to the secondary cell and the third value.

In one embodiment, the primary cell is in an active state, and the secondary cell is changed from a deactivated state to an active state, that is, both the primary cell and the secondary cell are in an active state. At this time, there are problems of mutual interference or power consumption heating between two or more radio frequency power amplifiers in the uplink path and/or performance degradation caused by that each path in the uplink path supports multiple working frequency bands, and so on, and therefore the uplink transmitting power corresponding to the main cell and the uplink transmitting power corresponding to the auxiliary cell are determined by subtracting a large wide-tolerance value from the configuration information.

In one embodiment, the second value represents a second wide tolerance value and the third value represents a third wide tolerance value. And the second value, namely the second wide tolerance value, is the wide tolerance value used when the uplink transmission power corresponding to the primary cell is determined when the primary cell is in the activated state and the secondary cell is also in the activated state. The third value, that is, the third wide-tolerance value, is a wide-tolerance value used when determining uplink transmission power corresponding to the secondary cell when the primary cell is in the activated state and the secondary cell is also in the activated 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 one embodiment, the second value and the third value are defined by a protocol. In one embodiment, the specific numerical values of the second value and the third value are indicated by at least one of RRC signaling, MAC-CE, and DCI.

In one embodiment, the status information is indicated by at least one of a MAC CE and DCI.
