Description

Power headroom report sending method and equipment

Technical Field

The embodiment of the application relates to the field of communication, in particular to a power headroom report sending method and device.

Background

In the conventional communication system, an uplink resource required for a terminal device to transmit uplink data is allocated by a network side. When the network side allocates uplink resources for the terminal device, the Power Headroom (PH) of the terminal device needs to be referred to. The PH is equal to a difference between a maximum transmission Power of the terminal device and an estimated transmission Power used by a currently transmitted Physical Uplink Shared Channel (PUSCH), and is calculated by the terminal device and reported to the network side in a Power Headroom Report (PHR). The PHR is configured to provide a difference between a transmission power used by an uplink synchronization Channel (UL-SCH) or a Sounding Reference Signal (SRS) and a maximum transmission power for a serving cell activated by a terminal device on a network side, or provide a difference between a transmission power used by a terminal device activated primary cell (a primary cell in a primary cell group or a primary cell in a secondary cell group) and/or a transmission power used by a Physical Uplink Control Channel (PUCCH) and a maximum transmission power for a serving cell configured with the PUCCH and the UL-SCH and the PUCCH on the network side.

In the existing standard protocol, a trigger condition for reporting the PHR by the terminal device and a format of the PHR reported in different scenarios (such as Dual Connection (DC) and Carrier Aggregation (CA)) are specified. However, the trigger condition and format specified in the existing standard protocol are for the case where only one uplink carrier is configured per Cell (Cell). For the case that each cell is configured with multiple (two or more) uplink carriers, if the terminal device reports the PHR according to the trigger condition and format specified by the existing standard protocol, the network side cannot accurately allocate uplink resources to the terminal device because an accurate PH reference cannot be obtained, thereby greatly reducing the accuracy of resource scheduling at the network side.

Detailed Description

The terms "first" and "second," and the like in the description and claims of this application and the above-described drawings are used for distinguishing between different objects and not for limiting a particular order.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

To facilitate a clear understanding of the following embodiments, a brief description of the related art is first given:

double Connection (DC): the mode is a mode of a terminal device in a Radio Resource Control (RRC) CONNECTED (RRC _ CONNECTED) state, and the terminal device is configured with a Master Cell Group (MCG) and a Secondary Cell Group (SCG). In the case where the radio access network supports DC, the terminal device in RRC _ CONNECTED state may be configured to use radio resources provided by two different base stations, one as a Master base station (Master eNB, MeNB) and one as a Secondary base station (SeNB), which are CONNECTED by an X2 interface. In the DC scenario, the terminal device is connected to one MeNB and one SeNB. Wherein, as shown in table 1, an MCG is a set of serving cells associated with an MeNB, consisting of a PCell (PCell refers to the primary cell of the MCG) and optionally one or more secondary cells (scells). An SCG is a set of serving cells associated with a SeNB, consisting of a PSCell (PSCell refers to the primary cell of an SCG) and optionally one or more scells.

TABLE 1

In addition, it should be noted that, as the communication technology evolves, the dual connectivity may change into multiple connectivity, for example, in the case that the radio access network supports multiple connectivity, the terminal device in the RRC _ CONNECTED state may be configured to use radio resources provided by three or more different base stations. The method provided by the embodiment of the application is also suitable for a multi-connection scene, and is specifically realized in a double-connection scene, and the double-connection scene is taken as an example in the application for explanation.

Carrier Aggregation (CA): carrier aggregation refers to that a terminal device can simultaneously use multiple Component Carriers (CCs) for uplink and downlink communication, thereby supporting high-speed data transmission. In the carrier aggregation technology, there may be a PCell, which is mainly used to undertake operations such as security, handover, uplink physical control channel bearer, etc., and other cells participating in aggregation are called scells, which undertake operations of data transmission only and do not involve security, handover, etc.

The network side allocates uplink resources for the terminal equipment and needs to refer to the PH of the terminal equipment in the cell. The PH is equal to a difference between the maximum transmission power of the terminal device in the cell and the estimated transmission power used for currently transmitting the PUSCH in the cell, and can be simply expressed as: PH is equal to UEAllowedMaxTransPower-PuschPower, wherein PH represents the power headroom, UEAllowedMaxTransPower represents the maximum transmission power of the terminal device in the cell, and PuschPower represents the transmission power currently used for transmitting PUSCH in the cell. The unit of PH is dB, the range is [ -23dB, +40dB ], if PH is negative value, it means that the network side schedules a data higher than its maximum transmission power to the terminal device.

In the existing standard protocol, a triggering condition for reporting the PHR by the terminal device and a format of the PHR reported in different scenes (such as DC and CA) are specified.

The trigger conditions specified by the existing standard protocol include the following six types:

1. and when the prohibit Timer (prohibit Timer) is overtime and the difference value between the path loss (pathloss) measured when the terminal equipment reports the PHR last time and the path loss measured currently is larger than a threshold value.

2. The arrival of a period of a periodic Timer (periodic Timer).

3. In the DC scenario, one PSCell is added.

4. In DC or CA scenarios, one SCell is activated.

5. When the terminal device performs PHR reconfiguration, for example, when the period of the periodic timer and the length of the timer are prohibited from being reconfigured.

6. The prohibit phr Timer is timed out, and a Media Access Control (MAC) entity has uplink resources available for transmission, and in a current Transmission Time Interval (TTI), the following conditions are satisfied for any activated SCell configured with the MAC entity: the cell has allocated uplink resources or PUCCH resources, and the change in the required power backoff value is greater than the change in the path loss of the uplink resources for transmitting PUCCH measured when the PHR is reported on the MAC entity configured in the cell last time.

The format of the PHR reported under different scenarios specified by the existing standard protocol is:

1. for a scenario in which a single cell is configured, the format of the PHR is shown in fig. 1. As can be seen from fig. 1, the PHR is one byte, where R is a reserved (reserve) bit, and PH is a power headroom of the terminal device in the cell.

2. For a configured multi-cell (at most 8 cells or at most 32 cells), and in a CA scenario, the format of the PHR is as shown in fig. 2 and 3. The PHR format shown in fig. 2 may be referred to as a PHR extension format (extensedphr), and the PHR format shown in fig. 3 may be referred to as an extensedphr 2 format. Fig. 2 (a) is a schematic structural diagram of a PHR when an SCell is configured with a PUCCH, and fig. 2 (b) is a schematic structural diagram of a PHR when an SCell is configured with a PUCCH, in the case of fig. 2 (a) is configured with 8 cells at most. Fig. 3 (a) is a schematic diagram of a PHR when an SCell is configured with a PUCCH in the case where 8 cells are configured at most, and fig. 3 (b) is a schematic diagram of a PHR when an SCell is configured with a PUCCH in the case where 32 cells are configured at most.

3. For a configured multi-cell (at most 8 cells or at most 32 cells), and in a DC scenario, the format of the PHR is as shown in fig. 4. The PHR format shown in fig. 4 may be referred to as a dual Connection PHR (dual Connection PHR) format. Fig. 4 (a) is a schematic structural diagram of a PHR in a case where 8 cells are configured at most, and fig. 2 (b) is a schematic structural diagram of a PHR in a case where 32 cells are configured at most.

In fig. 2 to 4, the Cx field is used to determine whether the SCell with index x reports the PH. When 8 cells are allocated at most, x takes a value of {1, 2, 3, …, 7}, and when 32 cells are allocated at most, x takes a value of {1, 2, 3, …, 31 }.

The R field is a reserved bit.

The P-domain is used to indicate whether power backoff is applied.

The value of V-field may be 0 or 1. When V is 1, it is used to indicate that the corresponding PH is a PH calculated based on the reference format, and when V is 0, it is used to indicate that the corresponding PH is a PH calculated based on the actual transmission

P_CMAX,CmThe field is used to represent the maximum transmission power of the corresponding cell. Wherein, when V is 1, P of corresponding cell does not need to be included_CMAX,C1A field.

A PH (Type 2, PCell) field for indicating a PH of the PCell under Type (Type) 2.

A PH (Type 1, PCell) field for indicating a PH of PCell under Type 1.

And a PH (Type X, SCell n) field used for indicating a PH of the SCell n under Type X, where a value of X may be 1 or 3, and n is an integer greater than 1 and is an index number of the SCell.

A PH (Type 2, PUCCH SCell) field to indicate a PH of the SCell configured with PUCCH in Type 2.

A PH (Type 2, PSCell) field to indicate the PH of a PSCell at Type 2.

Wherein Type1 refers to PH when only PUSCH is currently transmitted in a cell. Type2 refers to PH when PUCCH and PUSCH are currently transmitted simultaneously in a cell. Type3 refers to PH when only SRS is currently transmitted in a cell.

In addition, as shown in fig. 5, since the New Radio (NR) operating frequency band is higher, the terminal device in the cell edge area may receive a signal transmitted by the network side through the NR Downlink (DL), but the network side cannot receive the signal of the terminal device in the cell edge area due to the lower transmission power of the terminal device, that is, there is a problem of asymmetric uplink and Downlink coverage. To solve this problem, at least one low frequency band (e.g., a Long Term Evolution (LTE) band) is introduced to assist the terminal device to transmit Uplink data, so that the terminal device has at least two Uplink carriers to transmit Uplink data, which may be referred to as a Supplementary Uplink (SUL) technology. In a cell, among at least two Uplink carriers of a terminal device, an original Uplink carrier in a high frequency band may be referred to as a Primary Uplink (PUL), and the other introduced Uplink carriers in a low frequency band are referred to as SULs, that is, in the SUL technology, the terminal device may have one PUL and at least one SUL in a cell to solve the problem of asymmetric Uplink and downlink coverage. When the terminal equipment sends the uplink data to the access network equipment by adopting the same transmitting power, the transmission distance when the uplink data is sent on the PUL is longer than that when the uplink data is sent on the SUL.

It should be noted that, in at least two uplink carriers of the terminal device, the two names of the PUL and the SUL are only used for distinguishing the original high-frequency band uplink carrier from the introduced low-frequency band uplink carrier, and as the communication technology evolves, the names of the PUL and the SUL may change, and the embodiment of the present application is not specifically limited herein.

For example, referring to fig. 5, taking an example that a terminal device has one PUL and one SUL in one cell, a terminal device in an idle state may determine which uplink carrier of the PUL and the SUL is accessed by determining Reference Signal Received Power (RSRP) of a downlink signal, and when the RSRP exceeds a preset threshold, it indicates that the terminal device is in a central region of the cell (region 1 shown in fig. 5), and at this time, the terminal device may select the PUL for uplink access. And when the RSRP is lower than the preset threshold, it indicates that the terminal device is in the edge area of the cell (area 2 shown in fig. 5), and the terminal device selects the SUL for uplink access. When the uplink access of the terminal equipment is successful, the terminal equipment can enter a connection state, so that data transmission can be carried out.

It can be seen that in a scenario where the SUL technology is used, there may be a case where at least two uplink carriers may be configured in a cell (e.g., PCell, SCell, PSCell). In this case, if the terminal device needs to report the PH of the cell, it needs to report the PH of the cell for different uplink carriers in the cell. The trigger condition and format specified in the existing standard protocol are both for the case where only one uplink carrier is configured for a cell. At this time, if the terminal device reports the PHR according to the trigger condition and format specified by the existing standard protocol, the network side cannot accurately allocate uplink resources to the terminal device because the network side cannot obtain an accurate PH reference, thereby greatly reducing the accuracy of resource scheduling at the network side.

The method and the device aim to solve the problems that the network side cannot accurately allocate uplink resources to the terminal equipment due to the fact that accurate PH reference cannot be obtained, and accuracy of resource scheduling of the network side is greatly reduced. The embodiment of the application provides a method for sending a power headroom report, wherein in a scenario that a trigger condition is changed, a terminal device receives uplink carrier configuration from an access network device, the uplink carrier configuration is used for indicating configuration of at least two uplink carriers in at least one cell, and when the uplink carrier configuration changes, the terminal device triggers a PHR (Power Headroom), so that a network side can obtain an accurate PH reference by designing the trigger condition meeting an SUL (Surge engineering language) technology. Under the scene of changing PHR content, the terminal equipment receives configuration information from the access network equipment and sends PHR to the access network equipment according to the configuration information; wherein, this PHR includes: PH of at least two uplink carriers in at least one cell; alternatively, the PHR comprises: PH and first indication information of an uplink carrier in at least one cell; alternatively, the PHR comprises: a PH of an uplink carrier in at least one cell, wherein a Protocol Data Unit (PDU) received by a terminal device includes first indication information; the first indication information is used for indicating that the PH of one uplink carrier in at least one cell is reported, so that the network side can obtain an accurate PH reference by reporting the PHs of at least two uplink carriers in at least one cell or the PH and the indication information of one uplink carrier in at least one cell. Therefore, the network side can accurately allocate the uplink resources to the terminal equipment, and the accuracy of resource scheduling of the network side is improved.

It should be noted that, in this embodiment of the present application, a PHR includes PHs of at least two uplink carriers in at least one cell, which means that at least two uplink carriers exist in the PHs of multiple uplink carriers included in the PHR and belong to the same cell, that is, there is at least one cell that reports the PHs of at least two uplink carriers.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Fig. 9 is a flowchart illustrating a power headroom report sending method according to an embodiment of the present application, and as shown in fig. 9, the method may include:

401. and the access network equipment sends the uplink carrier configuration to the terminal equipment.

The uplink carrier configuration is used for indicating the configuration of at least two uplink carriers in at least one cell.

402. The terminal equipment receives the uplink carrier configuration from the access network equipment.

403. When the uplink carrier configuration changes, the terminal device triggers the PHR.

After the terminal device receives the configuration for indicating at least two uplink carriers in at least one cell from the access network device, that is, after receiving the uplink carrier configuration, the terminal device may determine whether the uplink carrier configuration changes, and when determining that the uplink carrier configuration changes, it indicates that PHR reporting may be triggered, and at this time, the terminal device may trigger the PHR so as to send the PHR to the access network device.

404. The access network equipment receives the PHR from the terminal equipment.

After the access network device receives the PHR from the terminal device, when uplink resource allocation is needed, allocation may be performed with reference to the received PHR.

In a specific implementation, the change of the uplink carrier configuration may include multiple cases, which are described in detail in the following cases.

In some embodiments, the specific change of the uplink carrier configuration may be: the uplink carrier corresponding to the resource indicated by the uplink scheduling information currently received by the terminal equipment is different from the uplink carrier corresponding to the resource adopted by the terminal equipment for sending uplink data last time; or the uplink carrier corresponding to the resource indicated by the uplink scheduling information currently received by the terminal device is different from the uplink carrier corresponding to the resource indicated by the uplink scheduling information last received by the terminal device.

Specifically, when the terminal device obtains new uplink scheduling (Grant) information, the terminal device may determine whether an uplink carrier corresponding to a resource indicated by the uplink scheduling information is the same as an uplink carrier corresponding to a resource used for last uplink data transmission, and trigger the PHR if the uplink carrier corresponding to the resource indicated by the uplink scheduling information is different from the uplink carrier corresponding to the resource used for last uplink data transmission. And if the uplink carrier corresponding to the resource indicated by the uplink scheduling information is the same as the uplink carrier corresponding to the resource used for sending the uplink data last time, not triggering the PHR. The uplink data may be a PHR, or other data sent by the terminal device to the access network device, which is not specifically limited herein in this embodiment of the present application;

and/or when the terminal device obtains new uplink scheduling information, the terminal device may determine whether an uplink carrier corresponding to a resource indicated by the uplink scheduling information is the same as an uplink carrier corresponding to a resource indicated by uplink scheduling information received last time, and trigger the PHR if the uplink carrier corresponding to the resource indicated by the uplink scheduling information is different from the uplink carrier corresponding to the resource indicated by the uplink scheduling information received last time. And if the uplink carrier corresponding to the resource indicated by the uplink scheduling information is the same as the uplink carrier corresponding to the resource indicated by the uplink scheduling information received last time, not triggering the PHR.

Wherein, the PHR at least includes a PH of an uplink carrier corresponding to a resource indicated by the currently received uplink scheduling information. For example, the uplink carrier corresponding to the resource indicated by the uplink scheduling information currently received by the terminal device is carrier a, the uplink carrier corresponding to the resource indicated by the uplink scheduling information received last time (or the uplink carrier corresponding to the resource used for sending uplink data last time) is carrier b, and carrier a is different from carrier b, at this time, the terminal device may trigger the PHR, and report the PHR at least including the PH of carrier b to the access network device. The carrier a and the carrier b may be different uplink carriers in the same cell, for example, the carrier a is a PUL in a PCell, and the carrier b is an SUL in the PCell, or different uplink carriers in different cells, for example, the carrier a is a PUL in a PSCell, and the carrier b is an SUL in an SCell.

Further, in order to trigger the PHR frequently when the access network device dynamically schedules multiple uplink carriers more frequently, the ProhibitTimer may be set to limit the frequency of triggering the PHR. For example, when the end device determines that the uplink carrier corresponding to the resource indicated by the currently received uplink scheduling information is different from the uplink carrier corresponding to the resource indicated by the uplink scheduling information received last time (or the uplink carrier corresponding to the resource used for transmitting uplink data last time), it may be further determined whether the ProhibitTimer is overtime, if the ProhibitTimer is overtime, the PHR is triggered, and if the ProhibitTimer is not overtime, the PHR is not triggered.

It should be noted that, in a specific implementation, the ProhibitTimer may reuse a ProhibitTimer in an existing standard protocol, or may reconfigure a timer. Under the condition of reconfiguring the ProhibitTimer, the timing time of the ProhibitTimer can be set according to the requirements of the actual application scene. In addition, the ProhibitTimer may be configured uniformly for uplink carriers in a cell, or may be configured separately for different uplink carriers, and the embodiment of the present application is not limited specifically herein.

In other embodiments, the specific change of the uplink carrier configuration may be: the uplink carrier corresponding to the resource configured with the physical uplink control channel (such as PUCCH) is changed from the first uplink carrier to the second uplink carrier.

It should be noted that, in this embodiment of the present application, the first uplink carrier and the second uplink carrier are different uplink carriers. For example, the first uplink carrier is a PUL in a PCell, and the second uplink carrier is a SUL in the PCell, or the first uplink carrier is a SUL in the PCell and the second uplink carrier is a PUL in an SCell, or the first uplink carrier is a SUL in the PCell and the second uplink carrier is a SUL in the SCell, which is not specifically limited in this embodiment of the present application.

Specifically, when the terminal device determines that an uplink carrier corresponding to a resource configured with a physical uplink control channel in a certain cell is changed from a first uplink carrier to a second uplink carrier, the terminal device triggers the PHR. Wherein, this PHR includes at least: the PH of the second uplink carrier in Type2, that is, the PHR includes Type2PH of the second uplink carrier. For example, if the uplink carrier corresponding to the resource in which the PUCCH is allocated is changed from the carrier c to the carrier d, the terminal device triggers the PHR, and carries at least Type2PH of the carrier d in the PHR. In this way, the terminal device triggers the PHR when the carrier corresponding to the configured PUCCH resource changes, so that the access network device can obtain a reference more quickly when the access network device schedules uplink resources on multiple uplink carriers of the terminal device.

In some other embodiments, the specific change of the uplink carrier configuration may be: in a dual connectivity scenario, the uplink carrier configuration of a Special Cell (SpCell) changes. Where SpCell refers to the PCell (primary cell) of MCG, the PSCell of SCG, and/or the PCell in the normal case (not configured with DC). That is, when the uplink carrier configuration of the SpCell changes, the terminal device triggers the PHR.

The specific change of the uplink carrier configuration of the SpCell is as follows: in a carrier aggregation scenario, an uplink carrier is added to a master cell in a master cell group, or the configuration of the uplink carrier configured on the master cell in the master cell group changes. Or, in a dual connectivity scenario, an uplink carrier is added to a primary cell in a primary cell group, or a configuration of an uplink carrier configured on the primary cell in the primary cell group changes, or an uplink carrier is added to a primary cell in an auxiliary cell group, or a configuration of an uplink carrier configured on the primary cell in the auxiliary cell group changes.

In this embodiment of the present application, adding an uplink carrier may refer to: resources configured with a physical uplink shared channel (such as a PUSCH) on the added uplink carrier; or, only the resources of the SRS are configured on the added uplink carrier. Optionally, when only the SRS is configured on the added uplink carrier, the PHR may not be triggered.

When the resource of the physical uplink shared channel is configured on the added uplink carrier under the condition that the PHR is triggered, reporting, by the terminal device, the PHR to the access network device at least includes: PH of the added uplink carrier in type 1. When only the resource of the SRS is configured on the added uplink carrier, the PHR reported to the access network device at least includes: increased uplink carrier PH in type 3. For example, in a carrier aggregation scenario, an uplink carrier e is added to the PCell, and the uplink carrier e is configured with resources of the PUSCH, the terminal device triggers a PHR, and reports the PHR to the access network device, where the PHR at least includes Type1PH of the uplink carrier e.

In this embodiment, the change in the configuration of the uplink carrier may include at least one of: the uplink carrier corresponding to the resource in which the physical uplink shared channel is allocated is reconfigured to an uplink carrier corresponding to only the resource in which the SRS is allocated, and the uplink carrier corresponding to only the resource in which the SRS is allocated is reconfigured to an uplink carrier corresponding to the resource in which the physical uplink shared channel is allocated.

Wherein, in case of triggering the PHR, when the configuration of the uplink carrier changes, the method includes: when the uplink carrier corresponding to the resource configured with the physical uplink shared channel is reconfigured to be the uplink carrier corresponding to the resource configured with the SRS, reporting to the PHR of the access network device at least includes: configuring the PH of the changed uplink carrier under the type 3; when the configuration of the uplink carrier is changed, the method comprises the following steps: when only the uplink carrier corresponding to the resource configured with the SRS resource is reconfigured to be the uplink carrier corresponding to the resource configured with the physical uplink shared channel, reporting to the PHR of the access network device at least includes: configuring the PH of the changed uplink carrier under the type 1. For example, in a dual connectivity scenario, PUL 1 and SUL 2 are configured on a PSCell, and a resource of a PUSCH is configured in the PUL 1, and when the resource of the PUSCH configured on the PUL 1 is reconfigured as a resource of an SRS, the terminal device triggers PHR reporting, and reports Type3PH including at least the PUL 1 to the access network device.

According to the power headroom report sending method provided by the embodiment of the application, the terminal device receives uplink carrier configuration from the access network device, the uplink carrier configuration is used for indicating the configuration of at least two uplink carriers in at least one cell, and when the uplink carrier configuration changes, the terminal device triggers the PHR, so that the access network device can obtain an accurate PH reference by designing a triggering condition meeting the SUL technology, the network side can accurately allocate uplink resources to the terminal device, and the accuracy of resource scheduling of the network side is improved.

Fig. 10 is a flowchart of another power headroom report sending method according to an embodiment of the present application.

As can be seen from fig. 2 to fig. 4, in the PHR in the ExtendedPHR format in the existing standard protocol, the terminal device reports Type2PH and Type1PH of the Pcell to the access network device, and reports Type x (x is 1 or 3) PH of the SCell in sequence according to the ascending manner of the cell index number.

The PHR in the extensedphr 2 format is different from the PHR in the extensedphr format in that Type2PH of Scell configured with PUCCH is added after Type2PH of Pcell.

A PHR in the dual Connection PHR format is different from a PHR in the ExtendedPHR format in that the Type2PH of the PSCell is added after the Type2PH of the Pcell.

It can be obtained that, in the format of the PHR defined in the existing standard protocol, the PHR only specifies how the PH of one uplink carrier (which may be considered as the PUL of the cell) of each cell is reported, and does not specify how the PH of the SUL of the cell is reported when at least two uplink carriers (one PUL and at least one SUL) exist in the cell. In order to meet a reporting requirement of a PH (that is, reporting a PH of at least one uplink carrier of a cell) that can be met in an SUL technology, an embodiment of the present application provides a power headroom report sending method, as shown in fig. 10, where the method may include:

501. and the access network equipment sends the configuration information to the terminal equipment.

The configuration information may include an uplink carrier configuration, where the uplink carrier configuration is used to indicate configurations of at least two uplink carriers in at least one cell.

502. The terminal equipment receives configuration information from the access network equipment;

503. and the terminal equipment sends the PHR to the access network equipment according to the configuration information.

After the terminal device receives the configuration information from the access network device, the PHR may be sent to the access network device according to the configuration information.

For example, the terminal device may send the PHR to the access network device according to the received configuration information when it is determined that the trigger condition is satisfied. The PHR includes: PH of at least two uplink carriers in at least one cell; alternatively, the PHR includes: PH and first indication information of an uplink carrier in at least one cell; alternatively, the PHR includes: PH of an uplink carrier in at least one cell, and the MAC PDU sent by the terminal equipment comprises first indication information; the first indication information is used for indicating that the PH of one uplink carrier in at least one cell is reported.

It should be noted that, in the embodiment of the present application, the triggering condition may be six conditions specified in an existing standard protocol, or an uplink carrier configuration change in the embodiment shown in fig. 9 of the present application may be used as the triggering condition, and the embodiment of the present application is not limited herein.

It should be further noted that, when the PHR includes PHs of at least two uplink carriers in at least one cell, the content specifically included in the PHR may be a PH of a first uplink carrier and a PH of at least one second uplink carrier in the at least one cell, where the first uplink carrier may be a PUL, and the second uplink carrier may be a SUL. Or the specifically included content of the PHR is a PH of a third uplink carrier and a PH of at least one fourth uplink carrier in the at least one cell, where the PH of the third uplink carrier is a PH calculated based on actual transmission, and the PH of the fourth uplink carrier is a PH calculated based on a reference format. Or, the content specifically included in the PHR is a PH of an uplink carrier of a first priority and a PH of an uplink carrier of at least one second priority in at least one cell, where the first priority is greater than the second priority, and the priority of each uplink carrier may be notified to the terminal device by the access network device or may be configured in advance.

In this scheme, when the PHR includes PHs of at least two uplink carriers in at least one cell, specifically, the content included in the PHR may be, for example, an extensedphr format under the condition that the PH of a third uplink carrier and the PH of at least one fourth uplink carrier in the at least one cell, as shown in fig. 11, for each cell requiring PH reporting, the PH of the third uplink carrier is preferentially reported. Thus, other uplink carriers in the cell are based on the reference format, so that the V domain of the uplink carrier shown in fig. 11 is meaningless and can be used to indicate whether the uplink carrier is a PUL. In addition, in the field for reporting the PH of the fourth uplink carrier, the V field may be considered as a reserved field, which may be used for other purposes to indicate information that needs to be indicated.

When the network side or the terminal device side only needs to report the PH of one uplink carrier for some reasons, the PHR may include the PH of one uplink carrier in at least one cell. The content specifically included in the PHR may be a PH of a first uplink carrier in at least one cell, for example, a PH including a PUL in at least one cell. Or, the content specifically included in the PHR is a PH of the third uplink carrier. Or, the content specifically included in the PHR is a PH of an uplink carrier of a first priority in at least one cell.

When the PHR includes PHs of at least two uplink carriers in at least one cell, the PHR may include PHs of multiple uplink carriers in the cell for which the terminal device wants to report the PHs by redesigning a format and content of the PHR.

For convenience of understanding, taking the PHs of a plurality of uplink carriers that the terminal device wants to report as the PH of one PUL and the PH of at least one SUL as an example. For PHR with three formats, an ExtendedPHR2 format and a dual Connection PHR format, the three existing formats may be redefined by adding a PH of each cell of a PH to be reported to the SUL in the PHR with each format and arranging the PHs in a preset order.

Of course, three new PHR formats may be newly defined, for example, a PHR corresponding to the extended PHR format, which is different only in the PH added with SUL, is referred to as an extended PHR 3 format, a PHR corresponding to the extended PHR2 format, which is different only in the PH added with SUL, is referred to as an extended PHR 4 format, and a PHR corresponding to the dual connectivity PHR format, which is different only in the PH added with SUL, is referred to as a dual connectivity PHR2 format.

It should be noted that, for a scenario in which three new PHR formats are redefined, the format names of the redefined three new PHR formats are not specifically limited in this embodiment of the application.

In addition, in the embodiment of the present application, the order of increasing the PH of the SUL of each cell to be reported with an SUL in the PHR of the existing format may be in the following two manners:

the first method is as follows: the PH of at least one SUL of the cell may be increased after the PH of the PUL of each of all cells that need to report the PH of the SUL according to the order of the cells, so as to form a new PHR format.

The second method comprises the following steps: the PH of the SUL of each cell in all cells that need to report the PH of the SUL may be added according to the order of the cells after the PHs of all the PULs to form a new PHR format.

For example, taking the extensedphr format as an example, referring to (a) in fig. 2, and assuming that the PH of the SUL of the cell to report the SUL is increased in the above manner, the new PHR format may be as shown in fig. 12. As can be seen from fig. 12, the extensedphr format is different from the extensedphr format shown in (a) of fig. 2 in that the PH of each cell of all cells in which the PH of the SUL to be reported is added, such as the PH (type X, Pcell, SUL 1), and the PH (type X, Pcell, PUL) is used to indicate the PH of the PUL of the cell. And, increasing the PH of at least one SUL of the cell after the PH of the PUL of each cell of all cells that need to report the PH of the SUL.

For example, taking the extensedphr 2 format as an example, referring to (a) in fig. 3, and assuming that the PH of the SUL of the cell to report the SUL is increased in the above-mentioned manner two, the new PHR format may be as shown in fig. 13. As can be seen from fig. 13, the format of extensedphr 2 shown in (a) of fig. 3 is different in that the PH of the SUL, such as PH (type X, Pcell, SUL 1), of each of all cells in which the PH of the SUL to be reported is added, and the PH (type X, Pcell, PUL) is used to indicate the PH of the PUL of the cell. And, after the PHs of all PULs, the PH of the SUL of each cell in all cells that need to report the PH of the SUL is increased according to the order of the cells.

It should be noted that, in the example shown in fig. 13, the PUCCHs of the PCell and the PUCCH SCell are both configured on the PUL, and for the case that the PUCCH is configured on the SUL, the PUCCH may be added at the same position, which is not described in detail herein. Moreover, when the PHs of the multiple uplink carriers that the terminal device wants to report are the PHs of the third uplink carrier and the at least one fourth uplink carrier, and the PHs of the uplink carriers of the first priority and the PHs of the uplink carriers of the at least one second priority, redesigning the format and the content of the PHR may refer to the description that the PHs of the multiple uplink carriers that the terminal device wants to report are the PHs of one PUL and the PHs of at least one SUL, which is not described herein again one by one.

In addition, when the PHR includes the PH of one uplink carrier in at least one cell, the terminal device may continue to use the PHR in the three formats of the extensedphr format, the extensedphr 2 format, and the dual Connection PHR format in the existing standard protocol. Therefore, the problem of resource waste caused by reporting the PHs of all uplink carriers together can be avoided.

In this embodiment of the present application, in order to distinguish whether the PHR reported by the terminal device includes PHs of at least two uplink carriers in at least one cell, the terminal device may carry indication information in the PHR or in a MAC PDU sent to the access network device, where the indication information is used to indicate whether the PHs of at least two uplink carriers in at least one cell are reported. When the indication information is a first value (equivalent to the first indication information in the present application), the indication information is used to indicate that the PH of an uplink carrier in at least one cell is reported. When the indication information is a second value (equivalent to the second indication information in the present application), the indication information is used to indicate that the PHs of at least two uplink carriers in at least one cell are reported.

It should be noted that, as an alternative, in the case that a new PHR format is defined, the indication information is also used to indicate the format of the PHR, so as to indicate whether the terminal device reports PHs of at least two uplink carriers in at least one cell. For example, the indication information is used to indicate that the format of the PHR is extensedphr 3, which may indicate that the PHs of at least two uplink carriers in at least one cell are reported, and if the format of the indication information is used to indicate that the PHR is extensedphr, which may indicate that the PHs of one uplink carrier in at least one cell are reported. Or, the indication information may also be used to indicate whether the PH of the second uplink carrier is included, or whether the PH of the fourth uplink carrier is included, or whether the PH of the second priority uplink carrier is included, so as to indicate whether the PHs of at least two uplink carriers in the at least one cell are reported. The embodiment of the present application does not specifically limit a specific implementation manner for indicating whether to report the PHs of at least two uplink carriers in at least one cell.

The following illustrates a specific implementation of the indication information, where the indication information is used to indicate whether to report PHs of at least two uplink carriers in at least one cell.

In some embodiments, the terminal device may carry the indication information in a MAC Control Element (CE) of the PHR. Specifically, an indication bit (bit) may be added to the MAC CE of the PHR to indicate whether the PHR includes PHs of at least two uplink carriers in at least one cell. When the method is specifically implemented, the following three alternatives and the combination of the three alternatives can be included:

alternative 1: it may be indicated by 1bit whether the PHR reports the PHs of at least two uplink carriers in the selected cell. Specifically, the reserved bits (R) in the bitmap (bitmap) as can be in the formats of the PHR shown in fig. 2-4 and fig. 11-13.

The following are exemplary: and R is 0, and is used for indicating that each cell in all the cells of the PH needing to be reported and indicated by the bitmap only reports the PH of one uplink carrier. For example, R ═ 0 is used to indicate that each cell of all cells whose PHs need to be reported are indicated by bitmap only reports the PH of the PUL in the cell, or only reports the PH of the third uplink carrier, or only reports the PH of the first priority uplink carrier.

The following are exemplary: and R is 1, and is used for indicating that each cell of all cells of the PH needing to be reported and indicated by the bitmap reports the PH of at least two uplink carriers. For example, R ═ 1 is used to indicate that each cell of all cells that need to report PHs and are indicated by the bitmap reports the PH of the first uplink carrier and the PH of at least one second uplink carrier, where the first uplink carrier may be the PUL and the second uplink carrier may be the SUL. Or, R ═ 1 is used to indicate that each cell in all cells that need to report PHs and indicated by the bitmap reports the PHs of the third uplink carrier and the PHs of at least one fourth uplink carrier. Or, R ═ 1 is used to indicate that each cell in all cells whose PHs need to be reported are indicated by the bitmap, reports the PH of the uplink carrier of the first priority and the PH of the uplink carrier of at least one second priority.

Alternative 2: a Bitmap may be added to the PHR formats shown in fig. 2-4 and fig. 11-13 to indicate which cells report PHs of at least two uplink carriers and which cells report PHs of one uplink carrier.

The number of the correspondingly configured cells is different, and the number of bits of the newly added bitmaps is also different. For example, a new 8-bit or 32-bit Bitmap may be added after the existing Bitmap, or a new 8-bit or 32-bit Bitmap may be added after the PHs of all PULs in the existing format, so as to indicate which cells report the PHs of at least two uplink carriers and which cells report the PH of one uplink carrier. If the value of a bit in the Bitmap is 1, the method is used to indicate that the cell corresponding to the bit reports the PHs of at least two uplink carriers, and if the value of a bit in the Bitmap is 0, the method is used to indicate that the cell corresponding to the bit reports the PH of one uplink carrier.

It should be noted that, in the embodiment of the present application, there is no particular limitation on the specific position of the newly added Bitmap in the PHR.

Alternative 3: for the uplink carrier reported with high priority in the cell (e.g., the first uplink carrier (e.g., PUL), or the uplink carrier with the first priority) based on actual transmission, the reserved bits in the bytes for indicating the maximum transmission power of the cell corresponding to the uplink carrier reported with high priority in the format of the PHR shown in fig. 2-4 and fig. 11-13 may be used to indicate whether the cell reports PHs of at least two uplink carriers.

In this case, considering that the uplink carrier reported by the low priority is based on the H of the reference format, and the byte corresponding to the fourth uplink carrier for indicating the maximum transmission power of the cell does not exist, at this time, the V domain thereof may be reused to indicate whether the uplink carrier is an SUL carrier.

In addition, for the case that the uplink carrier reported with high priority by a certain cell in option 3 is based on the reference format, it cannot be indicated by using the reserved bit in the byte used for indicating the maximum transmission power of the cell, and at this time, it may be specified to report only the PH of the uplink carrier with high priority in the cell (e.g., the first uplink carrier or the uplink carrier with the first priority), or to report the PHs of all uplink carriers in the cell. The scheme can be applied to a scene that uplink resources are not enough to report the PH values of all or a plurality of uplink carriers, so that the terminal equipment side can inform the access network equipment through the indication bit, and the reported PHR only contains the PH values of part of the uplink carriers with high priority.

In other embodiments, the terminal device may carry the indication information in the MAC PDU. Illustratively, the indication information may be carried in a sub-header of the MAC PDU. For example, an LCID different from an existing value may be used to indicate whether PH of at least two uplink carriers in at least one cell is reported.

504. The access network equipment receives the PHR from the terminal equipment.

After the access network device receives the PHR from the terminal device, when uplink resource allocation is needed, allocation may be performed with reference to the received PHR. For example, when the PHR includes PHs of at least two uplink carriers in at least one cell, the access network device may allocate uplink resources to the terminal device according to the PH of each uplink carrier of each cell in the at least one cell.

Further, in this embodiment of the present application, the access network device may indicate, through the control field, whether the terminal device reports PHs of at least two uplink carriers in at least one cell, or indicate a format of a PHR that needs to be reported.

In some embodiments, the indication may be included in configuration information (e.g., RRC configuration signaling). For example, the configuration information described in step 501 of the embodiment of the present application may include third indication information. Of course, the third indication information may not be included in the configuration information described in 501, but the network device sends the third indication information to the terminal device through other information, and the embodiment of the present application is not limited in this embodiment.

The third indication information may be used to indicate whether the terminal device reports PHs of at least two uplink carriers in at least one cell.

As an alternative, the third indication information may also be used to indicate whether the PH of the second uplink carrier is included, or whether the PH of the fourth uplink carrier is included, or whether the PH of the second priority uplink carrier is included, so as to indicate whether the PHs of at least two uplink carriers in the at least one cell are reported. The embodiment of the present application does not specifically limit a specific implementation manner for indicating whether to report the PHs of at least two uplink carriers in at least one cell. For example, a field may be added in the RRC configuration signaling to indicate whether the PH of the uplink carrier of the second priority is reported, or to indicate whether the PH of the SUL is reported.

In addition, in a specific implementation, the third indication information may also specifically indicate which specific cells of the terminal device need to report the PHs of the at least two uplink carriers, or be used to specifically indicate which specific cells of the terminal device do not need to report the PHs of the at least two uplink carriers (e.g., one PUL and at least one SUL), that is, only report the PH of one uplink carrier (e.g., PUL). Or, the third indication information may specifically indicate which cells of the terminal device need to specifically and respectively report the PHs of which n uplink carriers, where n is an integer greater than 1.

Or the third indication information is used to indicate a format of the PHR, where the PHR includes PHs of at least two uplink carriers in at least one cell when the format of the PHR is the first format, and the PHR includes a PH of one uplink carrier in at least one cell when the format of the PHR is the second format. The first format may be an ExtendedPHR 3 format, an ExtendedPHR 4 format, or a dialconnection PHR2 format, and the second format may be an ExtendedPHR format, an ExtendedPHR2 format, and a dialconnection PHR format. For example, if the new PHR format includes extensedphr 3 and extensedphr 4, it may be indicated in the control field of the RRC configuration signaling, such as PHR-Config:

PHR-Config information element

extendedPHR3 BOOLEAN OPTIONAL,--Need ON

extendedPHR4 BOOLEAN OPTIONAL,--Need ON

certainly, under the condition that the access network device indicates whether to report the PHs of the at least two uplink carriers in the at least one cell, when the terminal device reports the PHR, it may be indicated whether to report the PHs of the at least two uplink carriers in the at least one cell without adding indication information. The embodiments of the present application are not specifically limited herein.

According to the method for sending the power headroom report, the terminal equipment receives the configuration information from the access network equipment and sends the PHR to the access network equipment according to the configuration information; wherein, this PHR includes: PH of at least two uplink carriers in at least one cell; alternatively, the PHR comprises: PH and first indication information of an uplink carrier in at least one cell; alternatively, the PHR comprises: PH of an uplink carrier in at least one cell, and the MAC PDU received by the terminal equipment comprises first indication information; the first indication information is used for indicating that the PH of one uplink carrier in at least one cell is reported, so that the network side can obtain an accurate PH reference by reporting the PHs of at least two uplink carriers in at least one cell or the PH and the indication information of one uplink carrier in at least one cell, the network side can accurately allocate uplink resources to the terminal equipment, and the accuracy of resource scheduling of the network side is improved.
