Description

Power headroom report transmission method and device

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 device, an electronic device, and a computer readable storage medium.

Background technique

In the related art, the user equipment transmits a PHR (power headroom report) to the base station, so that the base station can determine to adjust the power of the user equipment according to the PHR.

SUL (Supplement UpLink) is introduced in NR (New Radio) to enhance uplink coverage. When a cell is configured with a SUL, the cell will correspond to two uplink carriers, one SUL carrier, and one non-SUL carrier.

Currently, in order to upload a PHR, the user equipment periodically transmits the PHR of the current working carrier to the base station. For example, when the current working carrier of the user equipment is a 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 that the working carrier of the user equipment is the SUL carrier in the next period, thereby The PHR that causes the non-SUL carrier cannot be reported in the next cycle, so that the base station cannot control the power of the non-SUL carrier for a long time.

In order to solve the problem in the above manner, another method is proposed in the related art. When the user equipment receives a base station indicating that the working carrier is switched, the PHR is triggered, and the PHR is transmitted to the base station. However, based on this manner, if the base station frequently instructs the serving cell to switch the working carrier, it will result in frequent triggering of the PHR and frequent transmission of the PHR to the base station, wasting resources of the user equipment.

Detailed ways

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. 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 obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

FIG. 1 is a schematic flow chart of a power headroom report transmission method according to an 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 following steps:

In step S1, before the first suppression timer is timed, the first working carrier after the serving cell handover carrier of the user equipment that is closest to the first suppression timer is determined, and the first suppression timer Whether the second working carrier of the serving cell is different after the timeout, wherein the first suppression timer is timed when the user equipment transmits a power headroom report to the base station, where the serving cell is configured to supplement the uplink carrier and the non- Supplement the uplink carrier;

In step S2, if different, the power headroom report is triggered, wherein the trigger power headroom report may be an identifier for generating a report about the trigger power headroom;

In step S3, the power headroom report of the second working carrier is transmitted to the base station.

In an embodiment, a first suppression timer may be set in the user equipment, where the first suppression timer may be timed when the user equipment transmits a power headroom report to the base station, for example, transmitting a power headroom report of the supplemental uplink carrier, or transmitting Power headroom report for non-supplemented uplink carriers.

In an embodiment, the user equipment may record the first working carrier after the serving cell handover carrier of the user equipment, which is the most recent time before the first suppression timer is timed, wherein the first working carrier It can be a supplementary uplink carrier or a non-additional uplink carrier. The second working carrier of the serving cell after the first suppression timer expires may be recorded, where the serving cell may switch the working carrier multiple times or does not switch the working carrier during the first suppression timer timing, and the second work The carrier may be the same as the first working carrier, or may be different from the first working carrier, for example, one carrier is an supplemental uplink carrier, and the other carrier is a non-supplemented uplink carrier.

In an embodiment, by setting a first suppression timer, the second working carrier of the cell may be served after the first suppression timer expires, and the serving cell of the user equipment is the last time before the first suppression timer is timed. When the first working carrier after the carrier is switched is different, the power headroom report of the second working carrier is transmitted to the base station. After the first suppression timer is timed but not timed out, even if the working carrier of the serving cell changes, there is no need to upload a power headroom report for the changed working carrier.

It should be noted that, in step S3, the serving cell needs to be allocated an uplink resource that can be used for transmitting new data, and the uplink resource can accommodate a medium access control layer control element of the power headroom report (MAC CE). In the case of the base station, the power headroom report of the second working carrier is transmitted to the base station.

By starting or restarting the second suppression timer, the second suppression timer can be re-timed to avoid repeatedly transmitting the power headroom report to the base station in a short time, thereby causing waste of uplink resources.

In an embodiment, the timer value of the first suppression timer may be indicated by an RRC message, according to which the timer value of the first suppression timer may be set as needed, and the timer value of the first suppression timer may be caused. It is the same as or different from the timer value of other timers.

In step S5, the trigger power headroom report is cancelled, wherein the trigger power headroom report is canceled, and the identifier about the trigger power headroom report may be deleted;

In step S6, the first suppression timer is started or restarted.

In an embodiment, after transmitting the power headroom report of the second working carrier to the base station, since the power headroom report has been transmitted to the base station after triggering the power headroom report for the serving cell, if the power remaining is still maintained If the quantity report is triggered, the power headroom report may be transmitted to the base station every time the carrier cell switches the carrier, so that the power headroom report is repeatedly transmitted to the base station in a short time, and the uplink resource is wasted. By canceling the triggering power headroom report and starting or restarting the second suppression timer, the first suppression timer can be re-timed, and the power remainder is triggered only when the second working carrier is different from the first working carrier. The quantity report avoids the waste of uplink resources caused by repeatedly transmitting power headroom reports to the base station in a short time.

FIG. 4 is a schematic flow chart of still another power headroom report transmission method according to an embodiment of the present disclosure. As shown in FIG. 4, based on the embodiment shown in FIG. 1, the method further includes:
