Technical Field
The present invention relates to the field of communications technologies, and in particular, to a Power Headroom Report (PHR) triggering method and a user terminal.
Background
In future communication systems (e.g., 5G communication systems), high frequency communication and large-scale antenna technologies will be introduced to achieve the goals of high downlink transmission rates (e.g., 20Gbps) and high uplink transmission rates (e.g., 10 Gbps). The high-frequency communication can provide a wider system bandwidth, and the antenna size can be smaller, which is more favorable for the deployment of large-scale antennas in network side Equipment and User Equipment (UE). The Multi-beam (Multi-beam)/Multi-receiving node (Multi-TRP) on the side of the network side equipment is used for transmitting and receiving, and the Multi-beam transmitting and receiving on the side of the UE can be widely applied. However, currently, PHR is reported based on carrier triggering, and one carrier may correspond to multiple beams, which means that the flexibility of reporting by triggering of PHR is relatively low.

and the triggering module is used for triggering the PHR report of the uplink wave beam or the uplink wave beam group or the uplink carrier if the uplink wave beam or the uplink wave beam group of the user terminal meets the triggering condition.
In a third aspect, an embodiment of the present invention provides a user terminal, including: the PHR triggering program is stored on the memory and can be operated on the processor, and when being executed by the processor, the PHR triggering program realizes the steps in the PHR triggering method provided by the embodiment of the invention.

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 network system applicable to the embodiment of the present invention, and as shown in fig. 1, the network system includes a user terminal 11 and a network side device 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 ue 11 may establish communication with the network-side device 12, where the network in the drawing may indicate that the ue 11 wirelessly establishes communication with the network-side device 12, and the network-side device 12 may be a Transmission Reception Point (TRP), or may be a base station, and the base station may be a macro station, such as an LTE eNB, a 5G NR NB, or the like; the network side device 12 may also be an Access Point (AP).
It should be noted that, in the embodiment of the present invention, the specific type of the network-side device 12 is not limited, and the specific functions of the user terminal 11 and the network-side device 12 will be described in detail through a plurality of embodiments below.
Referring to fig. 2, fig. 2 is a flowchart of a PHR triggering method provided in 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, judging whether the uplink beam or the uplink beam group of the user terminal meets the triggering condition.
The trigger condition may be obtained in advance, that is, obtained before step 201 is executed, for example: preset before performing step 201, or configured by the network side device.
In addition, in the embodiment of the present invention, different trigger conditions may be configured for different uplink beams or different uplink beam groups, and the same trigger condition may also be configured. In addition, the trigger condition may be that a timer expires, a downlink reference beam of the uplink beam changes, an activation message of the uplink beam is received, or a configuration message of the uplink beam is received.
Step 202, if the uplink beam or the uplink beam group of the user terminal meets the trigger condition, triggering PHR reporting of the uplink beam or the uplink beam group or the uplink carrier.
In step 202, the PHR of the uplink beam or the uplink beam group meeting the trigger condition may be triggered, or the PHR of the uplink beam or the uplink carrier corresponding to the uplink beam group meeting the trigger condition may be triggered. In addition, the triggering of PHR reporting may be to trigger an operation of PHR reporting to execute PHR reporting, and specifically may be to report to a network side device.
In addition, in the embodiment of the present invention, a PHR may be configured for each uplink beam or uplink beam group or uplink carrier, and each PHR may be reported when reporting.
In addition, in the embodiment of the present invention, if the uplink beam or the uplink beam group of the ue does not satisfy the trigger condition, the process may be ended, or step 201 may be continuously executed, where the ending process is illustrated in the figure.
The PHR reporting can be triggered based on the beam level through the steps, so that the PHR reporting can be triggered more flexibly.
In this embodiment, triggering of PHR of the uplink beam or the uplink beam group or the uplink carrier based on the uplink beam or the uplink beam group of the user terminal can be realized, so that triggering of PHR reporting is more flexible compared with reporting based on carrier triggering in the prior art.
Referring to fig. 3, fig. 3 is a flowchart of another PHR triggering method provided in an embodiment of the present invention, where the method is applied to a user equipment, and the main difference between this embodiment and the embodiment shown in fig. 2 is that reporting triggering of a PHR is performed based on one or more of a PHR prohibition timer of a beam, a downlink path loss variation of a beam, and a PHR timer of a beam period, as shown in fig. 3, the method includes the following steps:
step 301, if any one or more of configuration parameters of an uplink beam or an uplink beam group of the user terminal satisfy a trigger condition, determining that the uplink beam or the uplink beam group of the user terminal satisfies the trigger condition, where the configuration parameters include one or more of a PHR prohibition timer of a beam, a downlink path loss variation of a beam, and a PHR period timer of a beam.
The configuration parameters may be configured to the user terminal in advance by the network side device, or configured by the user terminal itself. The above-mentioned beam prohibit PHR-Timer may be configured with one prohibit PHR-Timer for each uplink beam, and certainly, the prohibit PHR-Timer for one beam may also correspond to multiple uplink beams. The PHR prohibition timer may be a prohibition control for PHR triggering, so as to prevent the user terminal from frequently triggering the corresponding PHR report, that is, after a PHR is triggered once, the user terminal will not trigger the PHR again before the timer is not overtime.
The downlink path loss variation (dl-pathloss change) of the beam may be that one downlink path loss variation is configured for each uplink beam, or of course, the downlink path loss variation of one beam may correspond to a plurality of uplink beams. The downlink path loss variation is a threshold for triggering the PHR by the downlink path loss variation, that is, the user terminal triggers the reporting of the corresponding PHR only when the downlink path loss variation reaches the threshold.
The periodic PHR timer of the beam may be configured for each uplink beam, and certainly, the periodic PHR timer of one beam may correspond to multiple uplink beams. The periodic PHR timer may be a timer controlled by periodically triggering the PHR, that is, when the periodic PHR timer is overtime, the ue will trigger the corresponding PHR to report.
In addition, it should be noted that the condition that the PHR timer for prohibiting the beam satisfies the trigger may be that the PHR timer is prohibited from being overtime, and the condition that the downlink loss variation of the beam satisfies the trigger may be that the downlink loss variation exceeds a specific threshold, and the condition that the periodic PHR timer of the beam satisfies the trigger may be that the periodic PHR timer is overtime.
Optionally, the uplink beam group is configured explicitly or implicitly by the network side device. The implicit configuration may be that the downlink beam references corresponding to the uplink beam all adopt one parameter configuration, for example: the uplink beams corresponding to the same downlink beam reference are grouped.
Step 302, if the uplink beam or the uplink beam group of the user terminal meets the trigger condition, triggering PHR reporting of the uplink beam or the uplink beam group or the uplink carrier.
In this embodiment, when any one of the PHR prohibition timer of the beam, the downlink path loss variation of the beam, and the PHR period of the beam satisfies the trigger condition, the PHR report of the uplink beam, the uplink beam group, or the uplink carrier may be triggered, so that the triggering flexibility of the PHR report is improved.
Referring to fig. 4, fig. 4 is a flowchart of another PHR triggering method provided in the embodiment of the present invention, where the method is applied to a user equipment, and the main difference between the embodiment and the embodiment shown in fig. 2 is that a downlink reference beam based on an uplink beam or an uplink beam group needs to be replaced to perform PHR reporting triggering, as shown in fig. 4, the method includes the following steps:
step 401, determining that the uplink beam or the uplink beam group of the user terminal satisfies the trigger condition if the uplink beam or the downlink reference beam of the uplink beam group of the user terminal needs to be replaced.
In the embodiment of the invention, one uplink beam corresponds to one downlink reference beam, or one uplink beam group corresponds to one downlink reference beam.
When the uplink beam or the downlink reference beam of the uplink beam group needs to be replaced, it may be determined that the downlink reference beam needs to be replaced when the user terminal detects that the downlink reference beam fails (beam failure) occurs, or it may be determined that the network side device configures the downlink reference beam and needs to be replaced. For example: if the uplink beam of the user terminal or the downlink reference beam of the uplink beam group needs to be replaced, determining that the uplink beam or the uplink beam group of the user terminal meets the trigger condition includes:
if the uplink beam of the user terminal or the downlink reference beam of the uplink beam group fails, determining that the uplink beam of the user terminal or the downlink reference beam of the uplink beam group needs to be replaced, and determining that the uplink beam or the uplink beam group of the user terminal meets the trigger condition; or
And if receiving a message which is sent by network side equipment and used for triggering the replacement of the uplink wave beam of the user terminal or the downlink reference wave beam of the uplink wave beam group, determining that the uplink wave beam or the uplink wave beam group of the user terminal meets the triggering condition.
The failure of the downlink reference beam of the uplink beam or the uplink beam group may be that the ue detects the failure of the uplink reference beam, for example: the uplink reference beam cannot be detected, or the uplink reference beam affects the corresponding uplink beam. In this case, an automatic backoff (fall back) is indicated to the downlink reference case (case), i.e., the downlink reference beam needs to be replaced. Another example is: for example, if the downlink beam 1 fails, the uplink beam X originally uses the downlink beam 1 as the path loss reference, and the downlink beam 1 fails, a downlink reference needs to be changed, and if the uplink beam X is automatically changed into the downlink beam 2 as the path loss reference at this time, the uplink beam X can trigger PHR reporting.
The message triggering the change of the uplink beam of the ue or the downlink reference beam of the uplink beam group may be that the network side device needs to change the downlink reference for the uplink beam for some reasons, and may notify the ue to change the downlink reference beam by using RRC (Radio Resource Control), MAC (Media Access Control), or physical layer signaling, so as to trigger PHR reporting.
Step 402, if the uplink beam or the uplink beam group of the user terminal meets the trigger condition, triggering PHR reporting of the uplink beam or the uplink beam group or the uplink carrier.
In this embodiment, when the uplink beam or the uplink reference beam of the uplink beam group needs to be changed, the PHR of the uplink beam or the uplink beam group or the uplink carrier may be triggered, so as to improve the flexibility of triggering the PHR, and the network side device may know the PHR of the user terminal in time.
Referring to fig. 5, fig. 5 is a flowchart of another PHR triggering method provided in an embodiment of the present invention, where the method is applied to a user terminal, and a main difference between this embodiment and the embodiment shown in fig. 2 is that reporting triggering of a PHR is performed based on a notification message sent by a network side device, and as shown in fig. 5, the method includes the following steps:
step 501, if receiving a notification message for configuring an uplink beam or an uplink beam group sent by a network side device, determining that the uplink beam or the uplink beam group of the user terminal satisfies the trigger condition.
In step 501, it may be implemented that if the network side device configures an uplink beam or an uplink beam group for the user terminal, it is determined that the uplink beam or the uplink beam group of the user terminal satisfies the trigger condition. Therefore, reporting of the PHR is realized according to the notification message of the network side equipment, so that the network side equipment can accurately know the PHR of the user terminal.
It should be noted that, in this embodiment, step 501 is replaceable, for example: step 501 may be replaced by: and if receiving a notification message for activating the uplink beam or the uplink beam group sent by the network side equipment, determining that the uplink beam or the uplink beam group of the user terminal meets the trigger condition.
In this embodiment, the PHR reporting may be triggered when the uplink beam or the uplink beam group is activated.
Step 502, if the uplink beam or the uplink beam group of the user terminal meets the trigger condition, triggering PHR reporting of the uplink beam or the uplink beam group or the uplink carrier.
Step 502 may be triggering PHR of the configured uplink beam or the uplink beam group, or triggering PHR of the configured uplink beam or the uplink carrier corresponding to the uplink beam group; or triggering the PHR of the activated uplink beam or uplink beam group, or triggering the PHR of the uplink carrier corresponding to the activated uplink beam or uplink beam group. Of course, in this embodiment, step 502 may also trigger PHR reporting of uplink beams or uplink beam groups other than configuration or activation, or corresponding uplink carriers, which is not limited in this embodiment of the present invention.
In this embodiment, when receiving a configuration or activation notification message sent by a network side device, triggering PHR of an uplink beam or an uplink beam group or an uplink carrier may be implemented, and triggering flexibility of PHR reporting may be improved.
Referring to fig. 6, fig. 6 is a flowchart of another PHR triggering method provided in the embodiment of the present invention, where the method is applied to a user equipment, and the main difference between this embodiment and the embodiment shown in fig. 2 is that reporting triggering of a PHR is performed based on the total transmit power of multiple uplink beams, as shown in fig. 6, the method includes the following steps:
step 601, if the total transmission power of the plurality of uplink beams of the user terminal exceeds the maximum transmission power of the user terminal, determining that the plurality of uplink beams meet the triggering condition.
The total transmission power of the multiple uplink beams may be a total transmission power of multiple beams (Multi-beams) in uplink of the user equipment.
Step 602, if the uplink beam or the uplink beam group of the user terminal meets the trigger condition, triggering PHR reporting of the uplink beam or the uplink beam group or the uplink carrier.
In step 602, the corresponding PHR may be triggered according to each uplink beam or each uplink beam group or each uplink carrier.
Optionally, if the total transmission power of the multiple uplink beams of the user terminal exceeds the maximum transmission power of the user terminal, determining that the multiple uplink beams satisfy a trigger condition includes:
if the total transmission power of a plurality of uplink beams of the user terminal exceeds the maximum transmission power of the user terminal and the user terminal discards part of uplink beams, determining that the uplink beams which are not discarded in the uplink beams meet a triggering condition;
if the uplink beam or the uplink beam group of the user terminal meets the trigger condition, triggering PHR reporting of the uplink beam or the uplink beam group or the uplink carrier, including:
and if the uplink beams which are not discarded in the uplink beams meet the triggering condition, triggering the uplink beams which are not discarded to be reported on PHRs of different carriers.
In this embodiment, when part of the uplink beams are discarded, the uplink beams not discarded may be triggered to report on the PHR of different carriers, so as to avoid unnecessary PHR reporting and save transmission resources. In addition, the reporting of the uplink beams that are not discarded in the PHR of different carriers may be that, when a certain uplink beam corresponds to multiple uplink carriers, the reporting of the PHR of the multiple uplink carriers corresponding to the uplink beam may be triggered. For example: the uplink beam 1 corresponds to the uplink carrier 1 and the uplink carrier 2, and can trigger PHR of the uplink beam 1 in the uplink carrier 1 and trigger PHR of the uplink beam 1 in the uplink carrier 2.
Optionally, if the total transmission power of the multiple uplink beams of the user terminal exceeds the maximum transmission power of the user terminal, determining that the multiple uplink beams satisfy a trigger condition includes:
if the total transmission power of a plurality of uplink beams of the user terminal exceeds the maximum transmission power of the user terminal and the transmission power of part of the uplink beams is adjusted, determining that the plurality of uplink beams meet the triggering condition;
if the uplink beam or the uplink beam group of the user terminal meets the trigger condition, triggering PHR reporting of the uplink beam or the uplink beam group or the uplink carrier, including:
and if the plurality of uplink beams meet the triggering condition, triggering PHR report of each beam.
In this embodiment, the transmission power of part of uplink beams can be adjusted to trigger PHR reporting of each beam. If some uplink beams correspond to multiple uplink carriers, the PHR of the uplink beam in the multiple uplink carriers may trigger reporting.
In this embodiment, when the total transmission power of the uplink beams exceeds the maximum transmission power of the user terminal, the PHR reporting may be triggered, so that the network side device may know the PHR of the user terminal in time, and the overall performance of the communication system may be improved.
