Description

Power headroom report transmission method and device

Technical Field

The present disclosure relates to the field of terminal technologies, and in particular, to a power headroom report transmission method, a power headroom report transmission apparatus, an electronic device, and a computer-readable storage medium.

Background

In LTE (Long Term Evolution), the ue may send a Power Headroom Report (PHR) to the base station, so that the base station adjusts the power of the ue according to the PHR.

In one embodiment, when the supplementary uplink carrier of the first cell is reconfigured, how the power headroom calculated by the first cell changes. For example, the first cell is not configured with a supplemental uplink carrier, but is configured with a supplemental uplink carrier, and then, when the first cell is not configured with a supplemental uplink carrier, the power headroom only needs to be calculated for other carriers, but when the first cell is configured with a supplemental uplink carrier, based on the embodiment shown in fig. 1, the power headroom needs to be calculated for other carriers as well as the supplemental uplink carrier, that is, the power headroom needs to be reported to the base station is changed, so that it can be determined that a trigger event exists, and the power headroom is calculated for the first cell again, so that the base station can accurately determine the power headroom of the first cell after the supplemental uplink carrier is reconfigured, and further it is ensured that the base station can accurately adjust the power of the user equipment according to the corresponding PHR.

Fig. 4 is a schematic flow chart diagram illustrating yet another triggering event for determining whether a power headroom report exists in accordance with an exemplary embodiment. As shown in fig. 4, on the basis of the embodiment shown in fig. 1, the determining whether there is a triggering event of power headroom report includes:

in step S13, it is determined whether the dynamic scheduling conditions of the physical uplink shared channel of the first cell on the supplemental uplink carrier and the other carriers change, and if so, it is determined that a trigger event exists.

In an embodiment, the change of the physical uplink shared channel from the non-dynamic scheduling to the dynamic scheduling in the supplemental uplink carrier and the other carriers means that the supplemental uplink carrier and the other carriers are configured with the physical uplink shared channel from one of the two carriers to the two carriers, and the physical uplink shared channel is configured in each of the two carriers. Correspondingly, the fact that the physical uplink shared channel is changed from dynamically-scheduled to dynamically-non-scheduled in the supplemental uplink carrier and the other carriers means that the supplemental uplink carrier and the other carriers are respectively configured with the physical uplink shared channel from the supplemental uplink carrier and the other carriers, and the physical uplink shared channel is configured in one of the supplemental uplink carrier and the other carriers.

For example, when the physical uplink shared channel is not dynamically scheduled in the supplemental uplink carrier and other carriers, for a carrier in which the physical uplink shared channel is not configured, the power headroom is calculated by referring to the power headroom when the user equipment assumes that the carrier in which the physical uplink shared channel is not configured is configured with the physical uplink shared channel; and when the physical uplink shared channel can be dynamically scheduled in the supplemental uplink carrier and other carriers, the actual power headroom of the carrier configured with the physical uplink shared channel is referred in calculating the power headroom. There is a difference in the power headroom referenced in these two cases.

Therefore, when the uplink carrier and other carriers of the physical uplink shared channel are changed from the non-dynamic scheduling to the dynamic scheduling, the trigger event is determined to exist, and the power headroom can be calculated for the first cell again, so that the base station can accurately determine the power headroom of the first cell after the uplink carrier is reconfigured, and the base station can be further ensured to accurately adjust the power of the user equipment according to the corresponding PHR.

Fig. 5 is a schematic flow chart diagram illustrating yet another triggering event for determining whether a power headroom report exists in accordance with an exemplary embodiment. As shown in fig. 5, on the basis of the embodiment shown in fig. 1, the determining whether there is a triggering event of power headroom report includes:

in step S14, it is determined whether a carrier on which a physical uplink control channel, a physical uplink shared channel, and/or a channel sounding reference signal of the first cell is located has changed, and if so, it is determined that a trigger event exists.

In an embodiment, when a carrier in which a PUCCH (Physical Uplink Control Channel) and/or a PUSCH (Physical Uplink Shared Channel) and/or an SRS (Sounding Reference Signal) of a first cell configured with a supplemental Uplink carrier is changed (including a case where a carrier in which any one of the PUCCH, the PUSCH, and the SRS is changed, a case where carriers in which both of the PUCCH, the PUSCH, and the SRS are changed, and a case where carriers in which all of the PUCCH, the PUSCH, and the SRS are changed, for example, the supplemental Uplink carrier is changed to another carrier, the other carrier is changed to a supplemental Uplink carrier, and the carrier is configured on a certain carrier to be not configured on any carrier, a power headroom calculation manner for the supplemental Uplink carrier and/or the other carriers may be changed.

For example, if the power headroom calculation method to be allocated to the first cell is the first power headroom calculation method and the second power headroom calculation method, and the PUSCH and the PUCCH are allocated to the supplemental uplink carrier before the PUCCH and/or the PUSCH and/or the SRS is changed, the power headroom is calculated by the second power headroom calculation method for the supplemental uplink carrier. After the change, the PUCCH is allocated from the supplemental uplink carrier to another carrier, and the calculation method of the power headroom is changed from the second power headroom calculation method to the first power headroom calculation method for the supplemental uplink carrier.

Since the power headroom calculated according to different power headroom calculation methods is different, according to this embodiment, when the carrier where the PUCCH, PUSCH, and/or SRS is located is changed, step S2 may be executed to re-determine the power headroom calculation method corresponding to each carrier of the first cell, thereby ensuring that the power headroom is accurately calculated, and further ensuring that the base station can accurately adjust the power of the user equipment according to the corresponding PHR.

Fig. 6 is a schematic flow chart diagram illustrating yet another triggering event for determining whether a power headroom report exists in accordance with an exemplary embodiment. As shown in fig. 6, on the basis of the embodiment shown in fig. 1, the determining whether there is a triggering event of power headroom report includes:

in step S15, after determining that a carrier where a physical uplink control channel, a physical uplink shared channel, and/or a channel sounding reference signal of the first cell is located is changed, determining whether the carrier where the channel sounding reference signal is located is different from the carrier where the link control channel and/or the physical uplink shared channel is located, and if so, determining that a trigger event exists.

In an embodiment, after a carrier where a PUCCH, PUSCH, and/or SRS of a first cell configured with a supplementary uplink carrier is located is changed, the SRS is different from the carrier where the PUCCH and PUSCH are located, that is, a power headroom calculation manner of a certain carrier of the supplementary uplink carrier and other carriers before the change is changed from a first power headroom calculation manner or a second power headroom calculation manner to a third power headroom calculation manner, so that by executing step S2, a calculation manner of a changed power headroom can be determined in time, so as to accurately calculate the power headroom, thereby ensuring that a base station can accurately adjust power of a user equipment according to a corresponding PHR.
