In order to facilitate the 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.

As people speed, latency, high-speed mobility, energy efficiency and the future of life in the pursuit of the business of diversity, complexity, for the third Generation Partnership Project ^{(3 rd Generation Partnership Project, 3GPP} ) ISO began the development of 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), Massive Machine-Type Communications (mMTC) ).

On the one hand, eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.

In the early deployment of NR, complete NR coverage is difficult to obtain, so the typical network coverage is wide-area LTE coverage and NR island coverage mode. Moreover, a large amount of LTE is deployed below 6GHz, and there is very little spectrum below 6GHz that can be used for 5G. Therefore, NR must study the spectrum application above 6GHz, and the high frequency band has limited coverage and fast signal fading. At the same time, in order to protect mobile operators' early investment in LTE, a tight interworking mode between LTE and NR is proposed.

In order to achieve 5G network deployment and commercial applications as soon as possible, 3GPP first completed the first 5G version, EN-DC (LTE-NR Dual Connectivity). In EN-DC, an LTE base station (eNB) serves as a master node (Master Node, MN), and an NR base station (gNB or en-gNB) serves as a secondary node (Secondary Node, SN) to connect 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 to connect to the 5GC core network. In 5GC-EN-DC, eLTE base station serves as MN, NR base station serves as SN, and connects 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 to connect to the 5GC core network.

The technical solutions of the embodiments of the present application can not only be applied to a dual-connectivity architecture (such as MR-DC architecture), but also can be applied to a multiple connectivity (Multiple Connectivity, MC) architecture. Typically, the MC architecture may be an MR-MC architecture.

RRC status

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

1) RRC_IDLE state (abbreviated as idle state): Mobility is UE-based 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 and no RRC connection on the base station side.

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

3) RRC_INACTIVE state (referred to as inactive state for short): Mobility is UE-based cell selection and reselection, there is a connection between CN-NR, UE context is stored on a certain base station, and paging is triggered by RAN, based on The paging area of the RAN is managed by the RAN, and the network side knows that the location of the UE is based on the paging area level of the RAN.

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. The types of PHR are: the first type PHR (type1PHR), the second type PHR (type2PHR), and the third type PHR (type3PHR). in,

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

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

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

Among them, PCMAX refers to the maximum transmission power of the terminal equipment (or the maximum transmission power supported by the terminal equipment).

It should be noted that the calculation of the above-mentioned PHR may be based on actual transmission calculation or based on reference virtual transmission calculation. Specifically, the calculation of the PHR based on actual transmission calculation means that the PHR is calculated according to the actual transmitted PUSCH, or PUSCH and PUCCH, or SRS. The calculation of PHR based on the reference virtual transmission calculation means that the PHR is calculated according to a reference format. It should be noted that the reference format of different types of PHR is different.

In the MR-DC scenario, the terminal device will report the PHR of all active cells of the terminal device, including the active cells on the MCG side and the active cells on the SCG side. For example: Figure 2 shows the format of the PHR reported to the NR base station. C _i (1≤i≤7) corresponds to the index of 1 serving cell, and C ₁ to C ₇ respectively correspond to the indexes of 7 serving cells. The value of C _i 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 It is applied to Power Management-Maximum Power Reduction (P-MPR) caused by power management. The information in the V domain is used to indicate whether the PHR calculation is based on an actual transmission or a reference format. The information in the PHR domain is PHR (also referred to as PH for short), where the type of the PHR can be type1PHR, type2PHR, or type3PHR, 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 P _CMAX,f,c , the PCMAX field is optional, and the information in the V field indicates that the PHR calculation is based on actual transmission, and the information in the P _CMAX,f,c ,V field needs to be carried In the case of indicating that the PHR calculation is based on the reference format, it is not necessary to carry P _CMAX,f,c (that is, P _{CMAX,f,c is} omitted and not transmitted).

Since the cells in the dual-connection scenario have a CG under the MN and a CG under the SN, for this, when reporting a PHR for one CG, how to correctly reflect the situation in the other CG is a problem that needs to be solved. To this end, the following technical solutions of the embodiments of the present application are proposed.
