Description
Technical Field
The present application relates to the field of communications 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 the related art, the user equipment transmits a Power Headroom Report (PHR) to the base station, so that the base station can determine to adjust the power of the user equipment according to the PHR.
A SUL (Supplement UpLink carrier) is introduced into NR (New Radio, New air interface) to enhance UpLink coverage. When a cell is configured with SUL, the cell will correspond to two uplink carriers, one SUL carrier and one non-SUL carrier.
Currently, in order to upload a PHR, a user equipment periodically transmits a PHR of a current operating carrier to a base station. For example, when the current working carrier of the ue is the SUL carrier, the PHR of the non-SUL carrier needs to be reported in the next period, and in some cases, the base station may still indicate the working carrier of the ue as the SUL carrier in the next period, so that the PHR of the non-SUL carrier cannot be reported in the next period, and the base station cannot control the power of the non-SUL carrier for a long time.
In order to solve the problems of the foregoing methods, another method is proposed in the related art, in which a PHR is triggered and transmitted to a base station whenever the ue receives an instruction from the base station to switch an operating carrier. However, in this way, if the base station frequently instructs the serving cell to switch the working carrier, the PHR is frequently triggered, and is frequently transmitted to the base station, which wastes resources of the user equipment.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flow chart diagram illustrating a power headroom report transmission method according to one embodiment of the present disclosure. The method described in this embodiment can be applied to user equipment, such as a mobile phone, a tablet computer, a wearable device, and the like. As shown in fig. 1, the power headroom report transmission method may include the steps of:
in step S1, before a first suppression timer counts time, determining whether a first operating carrier after a serving cell of the ue is switched to a carrier last time when the first suppression timer counts time is different from a second operating carrier of the serving cell after the first suppression timer expires, where the first suppression timer counts time when the ue transmits a power headroom report to a base station, and the serving cell is configured with a supplemental uplink carrier and a non-supplemental uplink carrier;
in step S2, if not, triggering a power headroom report, wherein the triggering of the power headroom report may be an identifier for generating a triggering power headroom report;
in step S3, a power headroom report of the second operating carrier is transmitted to the base station.
In one embodiment, a first suppression timer may be set in the user equipment, and the first suppression timer may be timed when the user equipment transmits a power headroom report to the base station, for example, transmits a power headroom report for a supplemental uplink carrier, or transmits a power headroom report for a non-supplemental uplink carrier.
In one embodiment, the ue may record a first working carrier after a serving cell of the ue switches carriers last time when the first suppression timer times before the first suppression timer times, where the first working carrier may be an additional uplink carrier or a non-additional uplink carrier. A second working carrier of the serving cell after the first suppression timer expires may also be recorded, where the serving cell may switch the working carrier or not switch the working carrier multiple times during the timing of the first suppression timer, and the second working carrier may be the same as the first working carrier or different from the first working carrier, for example, one carrier is a supplemental uplink carrier, and the other carrier is a non-supplemental uplink carrier.
In an embodiment, by setting the first suppression timer, the power headroom report of the second operating carrier may be transmitted to the base station when the second operating carrier of the serving cell after the first suppression timer expires is different from the first operating carrier after the serving cell of the ue switches carriers last time before the first suppression timer times. After the first suppression timer is timed and before the first suppression timer is timed out, even if the working carrier of the serving cell changes, the power headroom report does not need to be uploaded for the changed working carrier.
Therefore, even if the base station frequently instructs the serving cell to switch the working carrier, the period of the UE transmitting the power headroom report of the working carrier to the base station does not have the timer value of the cell first suppression timer, so that frequent transmission of the power headroom report to the base station is avoided, and uplink resources are saved.
In addition, under the condition that the second working carrier is different from the first working carrier, the power headroom report of the second working carrier can be transmitted to the base station, the power headroom report does not need to be transmitted to the base station according to a fixed period, and the base station can be prevented from being incapable of carrying out power control on the supplementary uplink carrier or the non-supplementary uplink carrier for a long time.
It should be noted that, in step S3, the serving cell is required to be allocated with uplink resources that can be used for transmitting new data, and the uplink resources can accommodate a medium access control layer control element (MAC CE) of a power headroom report, so as to transmit the power headroom report of the second working carrier to the base station.
Optionally, the serving cell is in an active state.
In an embodiment, it may be determined whether the first working carrier and the second carrier are different only by considering the cell in the active state, and for the cell in the inactive state, since the ue does not communicate through the cell in the inactive state, the base station does not need to control the power of the carrier, and thus it may not consider to reduce the occupation of the ue resources.
Optionally, the physical uplink shared channel of the serving cell is configured on a supplemental uplink carrier or a non-supplemental uplink carrier according to a message indication of a physical downlink control channel.
In one embodiment, if a Physical Uplink Shared Channel (PUSCH) of a serving cell is indicated to be configured by a Physical Downlink Control Channel (PDCCH) and indicates that the PUSCH can be configured on a supplemental Uplink carrier or a non-supplemental Uplink carrier, the PUSCH may be dynamically switched between the supplemental Uplink carrier and the non-supplemental Uplink carrier. The power headroom report may be transmitted according to the embodiment shown in fig. 1 only for such serving cells.
Optionally, the physical uplink shared channel of the serving cell is configured on a supplemental uplink carrier or a non-supplemental uplink carrier according to an RRC message indication.
In one embodiment, if a Physical Uplink Shared Channel (PUSCH) of a serving cell is configured as indicated by a Radio Resource Control (RRC) message, whether the PUSCH configuration is in a supplemental Uplink carrier or a non-supplemental Uplink carrier is relatively static. The power headroom report may be transmitted according to the embodiment shown in fig. 1 only for such serving cells.
Optionally, the timer value of the first suppression timer is the same as the timer value of the second suppression timer;
if the second suppression timer is overtime and the path loss change value of at least one service cell of the user equipment is greater than a preset path loss value, triggering a power headroom report; or
If the second suppression timer is overtime, and there is uplink resource available for transmitting new data, and at least one serving cell of the ue has an available physical uplink shared channel or an available physical uplink control channel, and a power backoff change value required by the serving cell having the available physical uplink shared channel or the available physical uplink control channel is greater than a preset backoff value.
In an embodiment, in case that the second suppression timer expires, if certain conditions are met, for example, a change value of a path loss of at least one serving cell of the ue is greater than a preset path loss value, or there is an uplink resource available for transmitting new data, and at least one serving cell of the ue has an available physical uplink shared channel or an available physical uplink control channel, and a change value of a power backoff required by a serving cell having an available physical uplink shared channel or an available physical uplink control channel is greater than a preset backoff value, the power headroom report may also be triggered.
By setting the timer value of the first suppression timer to be the same as the timer value of the second suppression timer, the number of characters required to be transmitted by the base station to configure the timer value can be reduced, thereby reducing the occupation of downlink resources.
Fig. 2 is a schematic flow chart diagram illustrating another power headroom report transmission method according to one embodiment of the present disclosure. As shown in fig. 2, on the basis of the embodiment shown in fig. 1, the method further includes:
in step S4, the second suppression timer is started or restarted.
In one embodiment, after the power headroom report of the second operating carrier is transmitted to the base station, since the power headroom report is already transmitted to the base station after the power headroom report is triggered for the serving cell, if the timing of the second suppression timer is still maintained, the power headroom report may be transmitted to the base station again when the second suppression timer is over time, so that the power headroom report is repeatedly transmitted to the base station in a short time, and uplink resources are wasted. By starting or restarting the second suppression timer, the second suppression timer can be restarted, so that waste of uplink resources caused by repeatedly transmitting a power headroom report to the base station in a short time is avoided.
Optionally, the timer value of the first suppression timer is indicated by an RRC message.
In one embodiment, the timer value of the first suppression timer may be indicated by an RRC message, whereby the timer value of the first suppression timer may be set as needed, and may be made the same as or different from the timer values of the other timers.
Fig. 3 is a schematic flow chart diagram illustrating yet another power headroom report transmission method according to one embodiment of the present disclosure. As shown in fig. 3, on the basis of the embodiment shown in fig. 1, the method further includes:
in step S5, canceling the triggered power headroom report, which may be deleting the identifier related to the triggered power headroom report;
in step S6, the first suppression timer is started or restarted.
In an embodiment, after the power headroom report of the second operating carrier is transmitted to the base station, since the power headroom report is already transmitted to the base station after the power headroom report is triggered for the serving cell, if the power headroom report trigger is still maintained, the power headroom report may be transmitted to the base station every time the carrier is switched by the serving cell, so that the power headroom report is repeatedly transmitted to the base station in a short time, and uplink resources are wasted. By canceling the trigger power headroom report and starting or restarting the second suppression timer, the first suppression timer can be restarted, and the power headroom report is triggered only when the second working carrier is different from the first working carrier, so that the waste of uplink resources caused by repeatedly transmitting the power headroom report to the base station in a short time is avoided.
Fig. 4 is a schematic flow chart diagram illustrating yet another power headroom report transmission method according to one embodiment of the present disclosure. As shown in fig. 4, on the basis of the embodiment shown in fig. 1, the method further includes:
in step S7, the cycle timer is started or restarted;
and if the periodic timer is overtime, triggering a power headroom report.
In one embodiment, after the power headroom report of the second working carrier is transmitted to the base station, since the power headroom report is already transmitted to the base station after the power headroom report is triggered for the serving cell, if the period timer is kept for timing, the power headroom report is transmitted to the base station when the period timer is timed out, so that the power headroom report is repeatedly transmitted to the base station in a short time, and uplink resources are wasted. By starting or restarting the periodic timer, the periodic timer can be restarted, so that waste of uplink resources caused by repeatedly transmitting a power headroom report to the base station in a short time is avoided.
