For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0049] 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.

[0050] With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of services in future life, the Third Generation Partnership Project (3GPP) rd The 3rd Generation Partnership Project (3GPP) international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0051] On the one hand, eMBB still aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0052] In the early days of NR deployment, complete NR coverage was difficult to obtain, so the typical network coverage was wide-area LTE coverage and NR island coverage. In addition, a large number of LTEs are deployed below 6GHz, and there is little spectrum below 6GHz available for 5G. Therefore, NR must study spectrum applications above 6GHz, but high-frequency bands have limited coverage and fast signal fading. At the same time, in order to protect mobile operators' early investments in LTE, a tight interworking working mode between LTE and NR was proposed.

[0053] In order to realize 5G network deployment and commercial applications as soon as possible, 3GPP first completed the first 5G version, namely EN-DC (LTE-NR Dual Connectivity). In EN-DC, the LTE base station (eNB) serves as the master node (Master Node, MN), and the NR base station (gNB or en-gNB) serves as the secondary node (Secondary Node, SN), connected to the EPC core network. In the later stage of R15, other DC modes will be supported, namely NE-DC, 5GC-EN-DC, and NR DC. In NE-DC, the NR base station serves as the MN and the eLTE base station serves as the SN, connected to the 5GC core network. In 5GC-EN-DC, the eLTE base station serves as the MN and the NR base station serves as the SN, connected to the 5GC core network. In NR DC, the NR base station serves as the MN and the NR base station serves as the SN, connected to the 5GC core network.

[0054] The technical solution of the embodiment of the present application can be applied not only to a dual-connectivity architecture (such as an MR-DC architecture), but also to a multiple-connectivity (MC) architecture. Typically, the MC architecture can be an MR-MC architecture.

[0055] RRC Status

[0056] In order to reduce air interface signaling and quickly restore wireless connections and data services, 5G defines a new Radio Resource Control (RRC) state, namely the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state.

[0057] 1) RRC_IDLE state (abbreviated as idle state): Mobility is based on UE cell selection and reselection, paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no UE context on the base station side and no RRC connection.

[0058] 2) RRC_CONNECTED state (referred to as connected state): There is an RRC connection, and UE context exists on the base station side and the UE side. The network side knows the location of the UE at the specific cell level. Mobility is mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.

[0059] 3) RRC_INACTIVE state (abbreviated as inactive state): Mobility is based on UE cell selection and reselection, there is a connection between CN and NR, the UE context exists on a certain base station, paging is triggered by RAN, and the RAN-based paging area is managed by RAN. The network side knows the UE location based on the RAN paging area level.

[0060] Power Headroom Report (PHR)

[0061] The terminal device reports PHR to the network side, which can assist the network side in better uplink data scheduling and uplink power control. The types of PHR are: first type PHR (type1 PHR), second type PHR (type2 PHR), and third type PHR (type3 PHR). Among them,

[0062] type1 PHR (dB) = PCMAX - PUSCH transmit power.

[0063] type2 PHR (dB) = PCMAX - (PUSCH transmit power and PUCCH transmit power).

[0064] type3 PHR (dB) = PCMAX - SRS transmit power.

[0065] Among them, PCMAX refers to the maximum transmission power of the terminal device (or the maximum transmission power supported by the terminal device).

[0066] It should be noted that the calculation of the above PHR can be based on actual transmission calculation or based on reference virtual transmission calculation. Specifically, the calculation of PHR based on actual transmission calculation means that PHR is calculated based on the actually transmitted PUSCH, or PUSCH and PUCCH, or SRS. The calculation of PHR based on reference virtual transmission calculation means that PHR is calculated based on a reference format. It should be noted that the reference formats of different types of PHR are different.

[0067] In the MR-DC scenario, the terminal device will report the PHR of all activated cells of the terminal device, including the activated cells on the MCG side and the activated cells on the SCG side. For example: Figure 2 This is the format of the PHR reported to the NR base station. i (1≤i≤7) corresponds to the index of one serving cell, and C1 to C7 correspond to the indexes of seven serving cells respectively. i The value of is used to indicate whether the PHR of the corresponding serving cell (Serving Cell) is reported. For the PHR of each serving cell (or carrier), it consists of 2 bytes, including the following information fields: P field, V field, PHR field, PCMAX field, where the information in the P field is used to indicate whether the power fallback caused by power management (Power Management-Maximum power Reduction, P-MPR) is applied. The information in the V field is used to indicate whether the PHR calculation is based on an actual transmission or a reference format. The information in the PHR field is PHR (also referred to as PH), where the type of PHR can be type1 PHR or type2 PHR or type3 PHR, but is not limited to this. The type of PHR can also be enhanced, such as typex PHR. The information in the PCMAX field is PHR. CMAX，f，c The PCMAX field is optional. The information in the V field indicates that the PHR calculation is based on the actual transmission, and P CMAX，f，c , the information in the V field indicates that the PHR calculation is based on the reference format, and there is no need to carry P CMAX，f，c (i.e. P CMAX，f，c Omitted for no transmission).

[0068] Since the cell in the dual-connection scenario has a CG under the MN and a CG under the SN, when reporting PHR for one CG, how to correctly reflect the situation in another CG is a problem that needs to be solved. To this end, the following technical solution of the embodiment of the present application is proposed.

[0069] Figure 3A flow chart of a method for reporting power headroom provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the method for reporting power headroom includes the following steps:

[0070] Step 301: A first network node receives first configuration information sent by a second network node, where the first configuration information includes a power headroom configuration on the second network node side.

[0071] In the embodiment of the present application, the first network node and the second network node are base stations. In an optional manner, the first network node and the second network node are two base stations in a dual-connection architecture, where the dual-connection architecture may be EN-DC, NE-DC, 5GC-EN-DC, NR DC, etc. In another optional manner, the first network node and the second network node are two base stations in a multi-connection architecture.

[0072] In an 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 an SN, and the second network node is an MN.

[0073] In an embodiment of the present application, the power headroom configuration on the second network node side is the same as the power headroom configuration configured by the second network node for the terminal device; or, the power headroom configuration on the second network node side is different from the power headroom configuration configured by the second network node for the terminal device; or, the second network node does not configure the power headroom configuration for the terminal device.

[0074] For example: MN notifies SN about the power headroom configuration on the MN side. The power headroom configuration on the MN side may be the same as the power headroom configuration configured by MN for the terminal device; or, the power headroom configuration on the MN side may be different from the power headroom configuration configured by MN for the terminal device; or, MN does not configure the power headroom configuration for the terminal device.

[0075] For example: SN notifies MN about the power headroom configuration on the SN side. The power headroom configuration on the SN side may be the same as the power headroom configuration configured by the SN for the terminal device; or, the power headroom configuration on the SN side may be different from the power headroom configuration configured by the SN for the terminal device; or, the SN does not configure the power headroom configuration for the terminal device.

[0076] Step 302: The first network node sends second configuration information to the terminal device, the second configuration information including the power headroom configuration on the first network node side and the power headroom configuration on the second network node side; wherein the second configuration information is used by the terminal device to report a power headroom report to the first network node.

[0077] In an embodiment of the present application, for the power headroom configuration on the first network node side and / or the power headroom configuration on the second network node side, the power headroom configuration includes at least one of the following: power headroom reporting configuration (i.e., configuration information about PHR reporting), power headroom calculation reference parameter configuration (i.e., expected PHR calculation reference parameter configuration).

[0078] In an optional manner, when the SN triggers PHR reporting, the power headroom configuration from the MN side (ie, the power headroom reporting configuration and / or the expected PHR calculation reference parameter configuration) is referred to when calculating the PHR of the serving cell on the MN side.

[0079] In another optional manner, when the MN triggers PHR reporting, the power headroom configuration from the SN side (ie, the power headroom reporting configuration and / or the expected PHR calculation reference parameter configuration) is referred to when calculating the PHR of the serving cell on the SN side.

[0080] In the above solution, optionally, the power headroom reporting configuration includes at least one of the following:

[0081] First indication information, where the first indication information is used to indicate whether the terminal device is configured with a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) for simultaneous transmission for one or more carriers;

[0082] 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;

[0083] 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;

[0084] Fourth indication information, the fourth indication information is used to indicate a list of carriers for which the terminal device needs to report power margin and / or a list of carriers for which the terminal device does not need to report power margin.

[0085] It should be noted that the description of "carrier" in the embodiments of the present application can also be replaced by "service cell" or "cell".

[0086] It should be noted that the description of the “first type of power headroom” in the embodiment of the present application may also be replaced by “type1 PHR”, wherein “type1 PHR” may also be abbreviated as “type1 PH”.

[0087] It should be noted that the description of the “second type of power headroom” in the embodiment of the present application may also be replaced by “type2 PHR”, where “type2 PHR” may also be abbreviated as “type2 PH”.

[0088] It should be noted that the description of the “third type of power headroom” in the embodiment of the present application may also be replaced by “type3 PHR”, where “type3 PHR” may also be abbreviated as “type3 PH”.

[0089] It should be noted that, for the above-mentioned fourth indication information, equivalently, the fourth indication information is used to indicate the whitelist or blacklist of the SCell list that needs to report PHR, wherein the whitelist refers to the list of carriers that need to report power margin, and the blacklist indicates the list of carriers that do not need to report power margin.

[0090] In the above solution, optionally, the power headroom calculation reference parameter configuration includes:

[0091] Fifth indication information, wherein the fifth indication information is used to indicate whether the power headroom of one or more carriers is the power headroom calculated according to actual transmission or the power headroom calculated according to reference virtual transmission.

[0092] In the embodiment of the present application, the first configuration information may be transmitted between the first network node and the second network node in any of the following ways:

[0093] Method 1: The first configuration information is carried in an inter-node message.

[0094] In an optional manner, the first configuration information is carried in CG-Config, and the SN notifies the MN about the power headroom configuration on the SN side (ie, the first configuration information) by sending the CG-Config to the MN.

[0095] In another optional manner, the first configuration information is carried in CG-Configinfo, and the MN notifies the SN about the power headroom configuration on the MN side (ie, the first configuration information) by sending CG-Configinf to the SN.

[0096] Mode 2: The first configuration information is carried in a message in a secondary node SN adding process. Optionally, the message in the SN adding process is a secondary node adding request message or a secondary node adding request confirmation message.

[0097] Mode 3: The first configuration information is carried in a message in the SN modification process. Optionally, the message in the SN modification process is a secondary node modification request message, a secondary node modification request confirmation message, or a secondary node modification confirmation message.

[0098] In an optional manner, 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 X2 interface.

[0099] For example: Refer to Figure 4-1 , the interface between MeNB and en-gNB is X2 interface, 1. MeNB sends SgNB add request message to en-gNB; 2. en-gNB sends SgNB add request confirmation message to MeNB. Among them, MeNB can send its own power headroom configuration to en-gNB in ​​SgNB add request message. Alternatively, en-gNB can send its own power headroom configuration to MeNB in ​​SgNB add request confirmation message.

[0100] For example: Refer to Figure 4-2 , the interface between MeNB and en-gNB is X2 interface, 1. MeNB sends SgNB modification request message to en-gNB; 2. en-gNB sends SgNB modification request confirmation message to MeNB. Among them, MeNB can send its own power headroom configuration to en-gNB in ​​SgNB modification request message. Alternatively, en-gNB can send its own power headroom configuration to MeNB in ​​SgNB modification request confirmation message.

[0101] For example: Refer to Figure 4-3 The interface between MeNB and en-gNB is X2 interface. 1. en-gNB sends SgNB modification request message to MeNB; 2. MeNB sends SgNB modification confirmation message to en-gNB. Among them, en-gNB can send its own power headroom configuration to MeNB in ​​SgNB modification request message. Alternatively, MeNB can send its own power headroom configuration to en-gNB in ​​SgNB modification confirmation message.

[0102] In an optional manner, 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.

[0103] For example: Refer to Figure 5-1, the interface between the M-NG-RAN node and the S-NG-RAN node is the Xn interface, 1. The M-NG-RAN node sends an SN add request message to the S-NG-RAN node; 2. The S-NG-RAN node sends an SN add request confirmation message to the M-NG-RAN node. Among them, the M-NG-RAN node can send its own power headroom configuration to the S-NG-RAN node in the SN add request message. Alternatively, the S-NG-RAN node can send its own power headroom configuration to the M-NG-RAN node in the SN add request confirmation message.

[0104] For example: Refer to Figure 5-2 , the interface between the M-NG-RAN node and the S-NG-RAN node is the Xn interface, 1. The M-NG-RAN node sends an SN modification request message to the S-NG-RAN node; 2. The S-NG-RAN node sends an SN modification request confirmation message to the M-NG-RAN node. Among them, the M-NG-RAN node can send its own power headroom configuration to the S-NG-RAN node in the SN modification request message. Alternatively, the S-NG-RAN node can send its own power headroom configuration to the M-NG-RAN node in the SN modification request confirmation message.

[0105] For example: Refer to Figure 5-3 , the interface between the M-NG-RAN node and the S-NG-RAN node is the Xn interface, 1. The S-NG-RAN node sends an SN modification request message to the M-NG-RAN node; 2. The M-NG-RAN node sends an SN modification confirmation message to the S-NG-RAN node. Among them, the S-NG-RAN node can send its own power headroom configuration to the M-NG-RAN node in the SN modification request message. Alternatively, the M-NG-RAN node can send its own power headroom configuration to the S-NG-RAN node in the SN modification confirmation message.

[0106] In an embodiment of the present application, the first network node sends second configuration information to the terminal device according to the power headroom configuration on 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 the power headroom configuration on the first network node side and the power headroom configuration on the second network node side.

[0107] Then, the terminal device reports a power headroom report to the first network node according to the second configuration information, and the first network node receives the power headroom report reported by the terminal device, and the power headroom report includes the power headroom information of the service cell on the first network node side and the power headroom information of the service cell on the second network node side.

[0108] Here, the power headroom report reported by the terminal device is carried in the PHR MAC CE. For example: the terminal device reports the PHR MAC CE to the SN, and the PHR MAC CE includes the power headroom information of the serving cell on the SN side and the power headroom information of the serving cell on the MN side. For example: the terminal device reports the PHR MAC CE to the MN, and the PHR MAC CE includes the power headroom information of the serving cell on the MN side and the power headroom information of the serving cell on the SN side.
