In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of the services in future life, the third generation partnership project (3) ^rd Generation Partnership Project, 3GPP) the international organization for standardization began developing 5G. The main application scenarios of 5G are: enhanced Mobile Ultra wide band (eMBB), Low-Latency high-reliability communication (URLLC), and massive Machine-Type communication (mMTC).

On the one hand, the eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said that it must be analyzed in detail in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

When NR is deployed early, complete NR coverage is difficult to obtain, so typical network coverage is wide area LTE coverage and islanding coverage mode of NR. Moreover, a large amount of LTE is deployed below 6GHz, and the spectrum below 6GHz available for 5G is rare. NR must therefore be studied for spectrum applications above 6GHz, with limited high band coverage and fast signal fading. Meanwhile, in order to protect the early LTE investment of a mobile operator, a light interworking (TIGHT) working mode between LTE and NR is provided.

In order to enable 5G network deployment and commercial applications as soon as possible, 3GPP first completes the first 5G release, namely EN-DC (LTE-NR Dual Connectivity). In EN-DC, an LTE base station (eNB) as a Master Node (MN) and an NR base station (gNB or EN-gNB) as a Secondary Node (SN) are connected to an EPC core network. Later in R15, other DC modes will be supported, namely NE-DC, 5GC-EN-DC, NR DC. In NE-DC, NR base station as MN, eLTE base station as SN, connect 5GC core network. In 5GC-EN-DC, an eLTE base station is used as MN, an NR base station is used as SN, and a 5GC core network is connected. In NR DC, an NR base station serves as MN and an NR base station serves as SN, and is connected to a 5GC core network.

The technical solution of the embodiment of the present application may be applied not only to a dual connection architecture (e.g., MR-DC architecture) but also to a Multi Connection (MC) architecture, and typically, the MC architecture may be an MR-MC architecture.

RRC state

5G defines a new Radio Resource Control (RRC) state, that is, an RRC INACTIVE (RRC _ INACTIVE) state, for the purpose of reducing air interface signaling, quickly recovering Radio connection, and quickly recovering data service. This state is distinguished from the RRC IDLE (RRC IDLE) state and the RRC ACTIVE (RRC ACTIVE) state. Wherein,

1) RRC _ IDLE state (IDLE state for short): mobility is UE-based cell selection reselection, paging is initiated by a Core Network (CN), and a paging area is configured by the CN. The base station side has no UE context and no RRC connection.

2) RRC _ CONNECTED state (CONNECTED state for short): there is an RRC connection and there is a UE context on the base station side and the UE side. The network side knows that the location of the UE is at a specific cell level. Mobility is network side controlled mobility. Unicast data may be transmitted between the UE and the base station.

3) RRC _ INACTIVE state (INACTIVE state for short): mobility is UE-based cell selection reselection, there is a connection between CN-NRs, UE context exists on a certain base station, paging is triggered by RAN, RAN-based paging area is managed by RAN, and network side knows that UE location is based on RAN's paging area level.

Power Headroom Report (PHR)

The terminal device reports the PHR to the network side, which can assist the network side to perform better uplink data scheduling and uplink power control. Types of PHR are: a first type PHR (type1PHR), a second type PHR (type2PHR), and a third type PHR (type3 PHR). Wherein,

type1phr (db) ═ PCMAX-PUSCH transmit power.

type2phr (db) ═ PCMAX- (PUSCH transmit power and PUCCH transmit power).

type3phr (db) ═ PCMAX-SRS transmit power.

Where PCMAX refers to the maximum transmission power of the terminal device (or the maximum transmission power supported by the terminal device).

It should be noted that the calculation of the PHR may be based on an actual transmission calculation or a reference virtual transmission calculation. Specifically, the calculation of the PHR based on the actual transmission calculation means that the PHR is calculated from the PUSCH, or the PUSCH and PUCCH, or the SRS, which is actually transmitted. The calculation of the PHR based on the reference virtual transmission calculation means that the PHR is calculated according to one reference format, and it should be noted that the reference formats of different types of PHR are different.

In an MR-DC scenario, the terminal device reports the PHR of all active cells of the terminal device, including an active cell on the MCG side and an active cell on the SCG side. For example: for example: fig. 2 shows a format of PHR reported to an NR base station. C _i (i is not less than 1 and not more than 7) index corresponding to 1 serving cell, C ₁ To C ₇ Corresponding to the indices of 7 serving cells, respectively. C _i The value of (2) is used for indicating whether the PHR of the corresponding Serving Cell (Serving Cell) reports. For a PHR of each serving cell (or carrier), it consists of 2 bytes, and includes the following information fields: a P domain, a V domain, a PHR domain, and a PCMAX domain, wherein information in the P domain is used to indicate whether Power Management-Maximum Power Reduction (P-MPR) is applied or not. For information in the V domainIndicating whether the PHR calculation is based on an actual transmission or a reference format. The information in the PHR field is a PHR (also referred to as simply PH), wherein the type of the PHR may be, but not limited to, a type1PHR or a type2PHR or a type3PHR, and the type of the PHR may also be enhanced, for example, a type x PHR. Information in the PCMAX domain is P _CMAX,f,c Optionally, the PCMAX domain is optional, and the information in the V domain indicates that the PHR calculation needs to be carried with P in case of actual transmission _CMAX,f,c In the case that the information in the V domain indicates that PHR calculation is based on the reference format, P does not need to be carried _CMAX,f,c (i.e. P) _CMAX,f,c Omit not transmit).

Because the cell under the double-connection scene has CG under MN and CG under SN, for this reason, when reporting PHR for one CG, how to correctly reflect the situation in the other CG is a problem to be solved. Therefore, the following technical scheme of the embodiment of the application is provided.

Fig. 3 is a flowchart illustrating a method for reporting power headroom according to an embodiment of the present invention, where as shown in fig. 3, the method for reporting power headroom includes the following steps:

step 301: a first network node receives first configuration information sent by a second network node, wherein the first configuration information comprises power headroom configuration of the second network node side.

In this embodiment, the first network node and the second network node are base stations. In an alternative, the first network node and the second network node are two base stations in a dual connectivity architecture, where the dual connectivity architecture may be EN-DC, NE-DC, 5GC-EN-DC, NR DC, etc. In another alternative, the first network node and the second network node are two base stations in a multi-connection architecture.

In this embodiment of the present application, the first network node is an MN, and the second network node is an SN; or, the first network node is a SN, and the second network node is a MN.

In this embodiment, the power headroom configuration of the second network node side is the same as the power headroom configuration of the terminal device configured by the second network node; or the power headroom configuration of the second network node side is different from the power headroom configuration of the terminal device configured by the second network node; or the second network node does not configure the power headroom configuration for the terminal device.

For example: the MN informs the SN about the power headroom configuration of the MN side. The power headroom configuration of the MN side may be the same as the power headroom configuration configured by the MN to the terminal device; or, the power headroom configuration of the MN side may be different from the power headroom configuration configured by the MN to the terminal device; alternatively, the MN does not configure the terminal device with a power headroom configuration.

For example: the SN informs the MN about the power headroom configuration on the SN side. The configuration of the power headroom at the SN side may be the same as the configuration of the power headroom configured by the SN to the terminal device; or, the power headroom configuration of the SN side may be different from the power headroom configuration configured by the SN to the terminal device; alternatively, the SN does not configure the terminal device with a power headroom configuration.

Step 302: the first network node sends second configuration information to a terminal device, wherein the second configuration information comprises power headroom configuration of the first network node side and power headroom configuration of the second network node side; wherein the second configuration information is used for the terminal device to report a power headroom report to the first network node.

In this embodiment of the present application, for the power headroom configuration at the first network node side and/or the power headroom configuration at the second network node side, the power headroom configuration includes at least one of the following: power headroom reporting configuration (i.e. configuration information on PHR reporting), power headroom calculation reference parameter configuration (i.e. expected PHR calculation reference parameter configuration).

In an alternative, in the case that the SN triggers PHR reporting, the power headroom configuration from the MN side is referred to when calculating the PHR of the serving cell of the MN side (i.e., the power headroom reporting configuration and/or the expected PHR calculation reference parameter configuration).

In another alternative, in the case that the MN triggers PHR reporting, the power headroom configuration from the SN side is referred to when calculating the PHR of the serving cell on the SN side (i.e., the power headroom reporting configuration and/or the expected PHR calculation reference parameter configuration).

In the foregoing scheme, optionally, the power headroom reporting configuration includes at least one of:

first indication information, where the first indication information is used to indicate whether a terminal device configures a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) for one or more carriers for simultaneous transmission;

second indication information, where the second indication information is used to indicate whether the terminal device reports a second type of power headroom for one or more carriers;

third indication information, where the third indication information is used to indicate whether the terminal device reports a third type of power headroom for one or more carriers;

and fourth indication information, where the fourth indication information is used to indicate a carrier list for which the terminal device needs to report the power headroom and/or a carrier list for which the terminal device does not need to report the power headroom.

It should be noted that, the description of the embodiment of the present application for the "carrier" may also be replaced by "serving cell" or "cell".

It should be noted that the description of the "first type of power headroom" in the embodiments of the present application may also be replaced by "type 1 PHR", where "type 1 PHR" may also be referred to as "type 1 PH" for short.

It should be noted that the description of the second type of power headroom in the embodiments of the present application may also be replaced by "type 2 PHR", where "type 2 PHR" may also be referred to as "type 2 PH" for short.

It should be noted that the description of the third type of power headroom in the embodiments of the present application may also be replaced by "type 3 PHR", where "type 3 PHR" may also be referred to as "type 3 PH" for short.

It should be noted that, for the fourth indication information, equivalently, the fourth indication information is used to indicate a white list or a black list of a list of scells that need to report a PHR, where the white list refers to a carrier list that needs to report a power headroom, and the black list indicates a carrier list that does not need to report the power headroom.

In the foregoing solution, optionally, the configuring of the power headroom calculation reference parameter includes:

fifth indication information for indicating whether a power headroom of one or more carriers is a power headroom calculated from an actual transmission or a power headroom calculated from a reference virtual transmission.

In this embodiment of the application, the first configuration information may be transmitted between the first network node and the second network node by any one of the following manners:

the first method is as follows: the first configuration information is carried in an inter-node (inter-node) message.

In an optional manner, the first configuration information is carried in CG-Config, and the SN informs the MN about the power headroom configuration (i.e. the first configuration information) on the SN side by sending CG-Config to the MN.

In another alternative, the first configuration information is carried in CG-configlnfo, and the MN informs the SN about the power headroom configuration of the MN side (i.e. the first configuration information) by sending CG-Configinf to the SN.

The second method comprises the following steps: and the first configuration information is carried in the information in the process of adding the auxiliary node SN. Optionally, the message in the SN adding process is an auxiliary node addition request message or an auxiliary node addition request confirmation message.

The third method comprises the following steps: the first configuration information is carried in a message in the SN modification process. Optionally, the message in the SN modification process is an auxiliary node modification request message, an auxiliary node modification request confirmation message, or an auxiliary node modification confirmation message.

In an alternative, the transmission of the message in the SN adding procedure or the transmission of the message in the SN modifying procedure may be implemented through an X2 interface.

For example: referring to fig. 4-1, the interface between the MeNB and the en-gNB is an X2 interface, and 1, the MeNB sends an SgNB addition request message to the en-gNB; 2. the en-gNB sends a SgNB addition request acknowledgement message to the MeNB. The MeNB may send the power headroom configuration of its own side to the en-gNB in the SgNB addition request message. Alternatively, the en-gNB may send its own power headroom configuration to the MeNB in a SgNB addition request acknowledge message.

For example: referring to fig. 4-2, the interface between the MeNB and the en-gNB is an X2 interface, and 1, the MeNB sends a SgNB modification request message to the en-gNB; 2. the en-gNB sends a SgNB modification request acknowledgement message to the MeNB. Wherein, the MeNB may send the power headroom configuration of its own side to the en-gNB in the SgNB modification request message. Alternatively, the en-gNB may send its own power headroom configuration to the MeNB in a SgNB modification request acknowledgement message.

For example: referring to fig. 4-3, the interface between the MeNB and the en-gNB is an X2 interface, and 1, the en-gNB sends an SgNB modification request message to the MeNB; 2. the MeNB sends a SgNB modification acknowledgement message to the en-gNB. Wherein the en-gNB can send the power headroom configuration of the self-side to the MeNB in the SgNB modification request message. Alternatively, the MeNB may send the power headroom configuration of its own side to the en-gNB in a SgNB modification acknowledgement message.

In an alternative, the transmission of the message in the SN adding process or the transmission of the message in the SN modifying process may be implemented through an Xn interface.

For example: referring to fig. 5-1, an interface between an M-NG-RAN node and an S-NG-RAN node is an Xn interface, and 1, the M-NG-RAN node transmits an SN addition request message to the S-NG-RAN node; 2. the S-NG-RAN node sends a SN addition request acknowledge message to the M-NG-RAN node. Wherein the M-NG-RAN node may send the power headroom configuration of its own side to the S-NG-RAN node in a SN addition request message. Alternatively, the S-NG-RAN node may send its own side power headroom configuration to the M-NG-RAN node in a SN addition request acknowledgement message.

For example: referring to fig. 5-2, an interface between an M-NG-RAN node and an S-NG-RAN node is an Xn interface, and 1, the M-NG-RAN node transmits an SN modification request message to the S-NG-RAN node; 2. the S-NG-RAN node sends a SN modification request acknowledgement message to the M-NG-RAN node. Wherein the M-NG-RAN node may send the power headroom configuration of its own side to the S-NG-RAN node in a SN modification request message. Alternatively, the S-NG-RAN node may send its own side power headroom configuration to the M-NG-RAN node in a SN modification request acknowledgement message.

For example: referring to fig. 5-3, an interface between an M-NG-RAN node and an S-NG-RAN node is an Xn interface, and 1, the S-NG-RAN node transmits an SN modification request message to the M-NG-RAN node; 2. the M-NG-RAN node sends a SN modification acknowledgement message to the S-NG-RAN node. Wherein the S-NG-RAN node may send the power headroom configuration of its own side to the M-NG-RAN node in a SN modification request message. Alternatively, the M-NG-RAN node may send its own side power headroom configuration to the S-NG-RAN node in a SN modification acknowledgement message.

In the embodiment of the application, the first network node issues the second configuration information to the terminal device according to the power headroom configuration of the second network node side, and accordingly, the terminal device receives the second configuration information sent by the first network node. Here, the second configuration information includes a power headroom configuration of the first network node side and a power headroom configuration of the second network node side.

And then, the terminal device reports a power headroom report to the first network node according to the second configuration information, the first network node receives the power headroom report reported by the terminal device, and the power headroom report comprises the power headroom information of the serving cell at the first network node side and the power headroom information of the serving cell at the second network node side.

Here, the power headroom report reported by the terminal device is carried in the PHR MAC CE. For example: and the terminal equipment reports PHR MAC CE to the SN, wherein the PHR MAC CE comprises power headroom information of the service cell at the SN side and power headroom information of the service cell at the MN side. For example: and the terminal equipment reports a PHR MAC CE to the MN, wherein the PHR MAC CE comprises power headroom information of a MN side service cell and power headroom information of an SN side service cell.

In an optional manner, the first network node forwards power headroom information of the serving cell on the second network node side to the second network node. For example: and the SN forwards the power headroom information of the MN side serving cell to the MN. For example: and the MN forwards the power headroom information of the service cell at the SN side to the SN.

It should be noted that the serving cell on the first network node side and/or the serving cell on the second network node side refer to a cell in an active state or a cell in an active state of a non-dormant behavior, where the active state of the non-dormant behavior refers to that an active BWP of the active cell is a non-dormant BWP.

Note that the active state has a sleep (dormant) behavior and a non-sleep (non-dormant) behavior. The terminal device may stay on the non-sleeping bwp (dormant bwp) to achieve the active state of the non-sleeping behavior.

In the technical scheme of the embodiment of the application, the second network node notifies the first network node of the power headroom configuration of the second network node side, so that the first network node can issue the power headroom configuration of the first network node side and the power headroom configuration of the second network node side to the terminal device together, the power headroom report reported to the first network node by the terminal device not only contains the power headroom information of the first network node side, but also includes the power headroom information of the second network node side, so that the terminal device reports a correct power headroom report to the network side, and the network side is assisted to make a correct and effective power function and scheduling.
