Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

Referring to fig. 1, fig. 1 is a structural diagram of a reporting system of a PHR according to an embodiment of the present invention, and as shown in fig. 1, the reporting system includes a user terminal 11 and a base station 12, where the user terminal 11 may be a ue (user equipment), for example: the terminal side Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present invention. The base station 12 may be a 5G base station (e.g., a gNB, a 5G NR NB), or may be a 4G base station (e.g., an eNB), or may be a 3G base station (e.g., an NB), and the like, and it should be noted that a specific type of the base station 12 is not limited in this embodiment of the present invention.

It should be noted that the specific functions of the user terminal 11 and the base station 12 are described in detail through a plurality of embodiments below.

Referring to fig. 2, fig. 2 is a flowchart of a reporting method for a PHR according to an embodiment of the present invention, where the method is applied to a user terminal, and as shown in fig. 2, the method includes the following steps:

step 201, obtaining PHR configuration information of BWP supported by the user terminal.

The BWPs supported by the ue may be one or more BWPs supported by the ue, for example: the ue may only support a relatively small operating bandwidth (e.g. 5MHz, 10MHz, or 20MHz, etc.), and a cell on the network side may support a relatively large bandwidth (e.g. 100MHz, 200MHz, or 400MHz, etc.), so that the BWP supported by the ue may be one or more BWPs in the bandwidth of the cell.

In addition, the above-mentioned acquisition may be sent by the receiving base station, or may be predefined by a protocol, or the user terminal stores in advance, etc. In addition, the PHR configuration information may indicate a BWP for which the power headroom and/or the maximum transmit power of the terminal need to be reported, may also indicate a trigger condition for reporting by the PHR of the user terminal, and may also indicate a content that the BWP needs to be reported, which is not limited in this embodiment of the present invention.

Step 202, reporting a PHR to a base station according to the PHR configuration information, wherein the PHR includes a power headroom of a BWP indicated by the PHR configuration information and/or a maximum transmission power of a terminal.

The power headroom and/or the terminal maximum transmission power may represent the power headroom or the terminal maximum transmission power, or represent the power headroom and the terminal maximum transmission power.

The step may be to acquire the power headroom of the BWP indicated by the PHR configuration information and/or the maximum transmission power of the terminal, generate the PHR, and report the PHR to the base station. In addition, the BWP indicated by the PHR configuration information may be one or more BWPs supported by the user terminal. And the power headroom and/or the maximum transmit power of the terminal reported by each BWP may be reported in the same manner or different manners.

In addition, if there are multiple BWPs that need to report the PHR, the UE may upload a corresponding PHR for each BWP, so that reporting the corresponding PHR on different BWPs can be achieved, thereby achieving more accurate power control for each BWP, saving the transmission power of the UE, and improving the quality of uplink transmission signals. Of course, the embodiment of the present invention is not limited thereto, for example: it is also possible that the power information of multiple BWPs is reported by the same PHR.

In this embodiment, PHR configuration information of a bandwidth portion BWP supported by the user terminal is obtained; reporting the PHR to a base station according to the PHR configuration information, wherein the PHR comprises the power headroom of the BWP indicated by the PHR configuration information and/or the maximum transmission power of the terminal. In this way, PHR reporting is carried out in a BWP layer, so that the accuracy of the uplink transmission power of the user terminal can be improved.

Referring to fig. 3, fig. 3 is a flowchart of a reporting method for a PHR according to an embodiment of the present invention, where the method is applied to a user terminal, and as shown in fig. 3, the method includes the following steps:

step 301, receiving PHR configuration information of BWP supported by the ue, which is sent by the base station.

Through step 301, the base station can configure the PHR configuration information for the user equipment, thereby improving the flexibility of the PHR configuration information. Of course, in this embodiment, step 301 is optional, and step 301 may be understood as a limitation to acquiring PHR configuration information of BWP supported by the user terminal, for example: acquiring PHR configuration information of BWP supported by the user terminal may also include:

and acquiring PHR configuration information of BWP supported by the user terminal, which is agreed by a protocol.

The obtaining of the PHR configuration information agreed by the protocol may be obtaining of the PHR configuration information stored in advance. In this embodiment, the PHR configuration information may be obtained by protocol agreement, so that signaling transmission overhead between the ue and the base station may be reduced. Of course, step 301 may also be directly replaced with obtaining PHR configuration information of BWP supported by the ue.

Optionally, the PHR configuration information includes at least one of:

reporting configuration of the PHR and a signaling format of the PHR.

The reporting configuration of the PHR may be a configuration related to the user terminal triggering the reporting of the PHR, for example: a timer or a reporting threshold, etc., that is, the reporting configuration indicates the user terminal to perform PHR reporting under which conditions, thereby improving the PHR reporting performance of the user terminal.

The signaling format of the PHR may be a content that the PHR needs to include, which indicates the power information that the user terminal needs to report through the signaling format, so as to improve the accuracy of reporting the PHR by the user terminal. It should be noted that, when the PHR configuration information includes the reporting configuration of the PHR and the signaling format of the PHR, the PHR configuration information may be obtained in multiple steps, for example: the reporting configuration of the PHR is sent by the receiving base station, and the signaling format of the PHR may be predefined by a protocol, or the signaling format of the PHR is sent by the receiving base station, and the reporting configuration of the PHR may be predefined by a protocol, and the like, which is not limited in the embodiment of the present invention.

Optionally, the reporting configuration of the PHR includes at least one of the following:

the method comprises the steps of periodically reporting a timer, forbidding reporting the timer, a downlink path loss change value and a power backoff change value.

The periodic reporting timer may be a timer for periodically triggering PHR reporting, the report prohibition timer may be a timer for prohibiting a user terminal from reporting the PHR during a running period, the downlink loss variation value may be a threshold of downlink loss, and the power backoff variation value may be a threshold of power backoff.

The reporting configuration can enable the user terminal to accurately report the PHR under a specific condition so as to improve the accuracy of the PHR reporting.

Optionally, the signaling format of the PHR indicates the format of the PHR through a display or implicit indication manner.

The format of the explicit indication PHR may be a format directly indicating the PHR through information content in configuration information of the PHR, for example: the information content in the configuration information indicates which BWPs need to report the PHR, and also indicates which contents need to be reported in the PHR, for example, the maximum transmission power of the terminal and/or the power headroom after the uplink physical channel transmission needs to be reported, so that the user terminal can be flexibly indicated to report the PHR, and the requirements of different services can be met by the flexibility of the user terminal. The format of the implicitly indicated PHR may be a format implicitly indicated by a configuration attribute of the BWP or a parameter of the BWP, and the user terminal may determine the PHR format of the BWP according to the configuration attribute or the parameter. For example: the configuration attribute of a certain BWP indicates the BWP configured with the maximum transmission power of the terminal and/or the power headroom after the uplink physical channel transmission, and implicitly indicates the BWP. Signaling overhead can be saved by implicitly indicating the format of the PHR, and the implicitly may further include indicating the format of the PHR in a pre-agreed manner, for example: it is pre-defined which BWPs are configured with PHR.

Optionally, the signaling format of the PHR indicates the following format of the PHR by a display indication manner:

reporting the maximum sending power of the terminal and/or BWP of the power margin after the uplink physical channel sending;

and/or the presence of a gas in the gas,

the maximum transmission power of the terminal and/or the BWP of the power margin after the uplink physical channel transmission do not need to be reported.

It should be noted that, in this embodiment of the present invention, the uplink physical channel includes at least one of an uplink control channel, an uplink data channel, an uplink sounding channel, and an uplink random access channel, that is, the maximum transmission power of the terminal and/or the power headroom after the uplink physical channel is transmitted may include at least one of the following:

the maximum sending power of the terminal and/or the power margin after the uplink physical channel is sent, the maximum sending power of the terminal and/or the power margin after the uplink data channel is sent, the maximum sending power of the terminal and/or the power margin after the uplink detection channel is sent, and the maximum sending power of the terminal and/or the power margin after the uplink random access channel is sent.

For example: the signaling format of the PHR indicates at least one of the following items through a display indication mode

Whether a BWP needs to report the maximum sending power of a terminal and/or the power margin after the uplink control channel is sent;

whether a BWP needs to report the maximum sending power of a terminal and/or the power margin after the uplink data channel is sent;

whether a BWP needs to report the maximum sending power of a terminal and/or the power margin after the uplink detection channel is sent;

whether a BWP needs to report the maximum sending power of a terminal and/or the power margin after the uplink random access channel is sent;

the Uplink control Channel may be a Physical Uplink Control Channel (PUCCH), the Uplink data Channel may be a Physical Uplink Shared Channel (PUSCH), the Uplink Sounding Channel may be an Uplink Channel for transmitting a Sounding Reference Signal (SRS), and the Uplink random access Channel may be a Physical Random Access Channel (PRACH).

In this embodiment, it may be achieved to indicate to the ue which BWPs need to report the power headroom and/or the maximum transmit power of the ue, and which BWPs do not need to report the power headroom and/or the maximum transmit power of the ue, thereby further improving the accuracy of PHR.

Optionally, the signaling format of the PHR indicates at least one of the following by an implicit indication manner:

the BWP configured with the maximum transmission power of the terminal and/or the power headroom after the transmission of the uplink physical channel and the BWP not configured with the maximum transmission power of the terminal and/or the power headroom after the transmission of the uplink physical channel.

The uplink physical channel may refer to the uplink physical channel in the above embodiment, which is not described herein again.

In this embodiment, some BWPs may be configured with the maximum transmission power of the terminal and/or the power headroom after the uplink physical channel transmission, or some BWPs may not be configured with the maximum transmission power of the terminal and/or the power headroom after the uplink physical channel transmission, for example: the signaling format of the PHR indicates at least one of the following items by an implicit indication mode:

whether a certain BWP is configured with the maximum transmission power of a terminal and/or the power margin after the transmission of an uplink control channel;

whether a certain BWP is configured with the maximum sending power of a terminal and/or the power margin after the sending of an uplink data channel;

whether a certain BWP is configured with the maximum sending power of a terminal and/or the power margin after the uplink detection channel is sent;

whether a certain BWP is configured with the maximum transmission power of the terminal and/or the power headroom after the uplink random access channel transmission.

Therefore, the user terminal can only report the power headroom of the BWP configured with the maximum transmission power of the terminal and/or the power headroom after the transmission of the uplink physical channel and/or the maximum transmission power of the terminal, so as to improve the accuracy of PHR.

Step 302, reporting a PHR to a base station according to the PHR configuration information, wherein the PHR includes a power headroom of a BWP indicated by the PHR configuration information and/or a maximum transmission power of a terminal.

Optionally, the reporting the PHR to the base station according to the PHR configuration information includes:

The PHR trigger condition may be configured in the PHR configuration information, for example: the PHR configuration information includes a trigger condition indicated by reporting configuration of the PHR. Or the PHR trigger condition may be preset by the user terminal or the like,

in the embodiment, reporting can be realized only when the PHR trigger condition is met, so that the accuracy of reporting the PHR by the user terminal can be improved. It should be noted that, in the embodiment of the present invention, reporting is not limited to meeting the PHR trigger condition, for example: and reporting at the moment of protocol agreement or base station configuration, and the like.

Optionally, if the PHR trigger condition is met, reporting the PHR to the base station according to the PHR configuration information, where reporting the PHR to the base station includes:

if at least one condition content in the PHR triggering conditions is met, reporting the PHR to a base station according to the PHR configuration information;

adding, deleting, or modifying a configuration of at least one BWP;

and prohibiting the report timer from being overtime, wherein the power back-off change value of at least one activated BWP exceeds the power back-off change value acquired by the user terminal.

If the report prohibition timer of the ue expires and the downlink loss variation value of at least one activated BWP exceeds the downlink loss variation value acquired by the ue, the PHR reported to the base station may be a PHR corresponding to each BWP in the at least one BWP, or may also be a PHR including power information of the at least one BWP. Similarly, the at least one BWP is activated or deactivated, then the PHR reported to the base station may be a PHR corresponding to each BWP in the at least one BWP, or may also be a PHR including power information of the at least one BWP. Similarly, the configuration of the at least one BWP is added, deleted or modified, and then the PHR reported to the base station may be a PHR corresponding to each BWP in the at least one BWP, or may also be a PHR including power information of the at least one BWP. Similarly, if the report timer is prohibited from being timed out and the change value of the power backoff of at least one active BWP exceeds the change value of the power backoff obtained by the ue, the PHR reported to the base station may be a PHR corresponding to each BWP in the at least one BWP or may also be a PHR including power information of the at least one BWP.

In this embodiment, reporting the PHR to the base station can be achieved if the user terminal meets the at least one condition, so that accuracy of reporting the PHR by the user terminal can be improved. In addition, in this embodiment, each BWP in the at least one BWP may report its PHR to satisfy the above condition, or report a PHR, where the PHR may include power information of one or more BWPs.
