The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

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

In order to reduce air interface signaling, quickly recover wireless connection, and quickly recover data service, 5G defines a new Radio Resource Control (RRC) state, that is, an RRC INACTIVE (RRC _ INACTIVE) state. 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 (type1 PHR), a second type PHR (type2 PHR), and a third type PHR (type3 PHR). Wherein,

type1phr (db) ═ PCMAX-PUSCH transmit power.

type2 phr (db) ═ PCMAX- (PUSCH transmit power and PUCCH transmit power).

type3 phr (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 a single-cell scenario (i.e., a scenario in which dual connectivity is not configured and uplink carrier aggregation is not configured), the terminal device reports the PHR of a single cell, as shown in fig. 2-1.

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: fig. 2-2 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 the PHR of each serving cell (or carrier),consists of 2 bytes and comprises the following information fields: the system comprises a P domain, a V domain, a PHR domain and a PCMAX domain, wherein information in the P domain is used for indicating whether P-MPR is applied or not. 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 field is a PHR (also referred to as simply PH), wherein the type of the PHR may be, but not limited to, type1PHR or type2 PHR or type3 PHR, and the type of the PHR may also be enhanced, for example, 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).

To meet the higher bandwidth and rate requirements, more secondary nodes may be introduced, and accordingly, a situation of configuring multiple SCGs may occur, for example, as shown in fig. 3-1 and fig. 3-2, in a scenario where a terminal device is configured with multiple SCGs, the multiple SCGs may all be activated, or may be partially activated, or only one SCG is activated. For a scenario where multiple SCGs are configured, it is clear how to report the PHR, compared with configuring a single SCG. Therefore, the following technical scheme of the embodiment of the application is provided.

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". Also, the description for "cell" or "serving cell" may be replaced with "carrier".

It should be noted that the description of the embodiment of the present application for the "first type power headroom" 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 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 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.

Fig. 4 is a flowchart illustrating a method for reporting power headroom according to an embodiment of the present application, where as shown in fig. 4, the method for reporting power headroom includes the following steps:

step 401: the method comprises the steps that a terminal device sends a PHR MAC CE to a network device, wherein the PHR MAC CE comprises PHRs of a plurality of cells, and the cells belong to a plurality of cell groups CG.

In this embodiment of the present application, the terminal device encapsulates the PHR MAC CE according to a first rule, where the first rule is: PHRs of the plurality of cells are ordered in the PHR MAC CE based on at least one of: CG index, serving cell index, power headroom type. Then, the terminal device transmits the PHR MAC CE to the network device, and accordingly, the network device receives the PHR MAC CE transmitted by the terminal device. Further, optionally, the network device is a base station, such as a MN or a SN.

Here, for each of the plurality of cells, at least one of the following information is associated: CG index, serving cell index, power headroom type. The index of the CG is an index of the CG to which the cell belongs, the Serving cell index (Serving cell index) of the cell, and the power headroom type is a type of power headroom (e.g., a first type power headroom, a second type power headroom, or a third type power headroom) reported by the terminal device for the cell. And the terminal equipment encapsulates the PHR of each cell into the PHR MAC CE according to the at least one information related to each cell in the plurality of cells.

The first rule may be also referred to as a "rule for assembling PHR MAC CE", and the "format of PHR MAC CE" may be equivalently determined by the "rule for assembling PHR MAC CE".

In an optional manner of the present application, the first rule is agreed by a protocol. And the terminal equipment encapsulates the PHR MAC CE according to a first rule. For example: when the report of PHR is triggered, the terminal equipment generates PHR MAC CE according to a first rule agreed by a protocol.

In another optional manner of this application, the first rule is configured for a network device. And the terminal equipment encapsulates the PHR MAC CE according to a first rule. For example: the network device configures the format of the PHR MAC CE or the rule (i.e., the first rule) for assembling the PHR MAC CE by the terminal device through the dedicated RRC signaling. When the report of PHR is triggered, the terminal equipment generates PHR MAC CE according to a first rule configured by the network equipment.

In the embodiment of the present application, when the PHR is triggered, and when a terminal device assembles a PHR MAC CE, the PHR MAC CE carries all active cells of the terminal device and/or PHR of an active cell with a dormant behavior. Here, the activated cell refers to a cell in an activated state, and the activated cell with a dormant behavior indicates a cell in an activated state with a dormant behavior, where it should be noted that the activated state with a dormant behavior may be implemented by: the active BWP of the active cell is an non-dormant BWP.

For a scenario of multiple SCGs, the PHR MAC CE includes a PHR of a serving cell in a first state and/or a PHR of a serving cell in a second state in at least one activated SCG; wherein the first state refers to an active state and the second state refers to an active state with non-sleep behavior.

For example: for the 3 SCG scenario, there are 2 active cells and 1 active cell with dormant behavior in SCG1, 1 active cell with dormant behavior in SCG2, and 1 active cell in SCG 3. Then, when the PHR of any cell in the cells is triggered, the PHR MAC CE carries the PHR of each cell in the cells when the terminal device assembles the PHR MAC CE.

In the embodiment of the present application, a terminal device encapsulates a PHR MAC CE according to a first rule, and the implementation of the first rule is described below with reference to different cases.

The terminal equipment fills a second type power margin and a first type power margin of a cell in sequence from small to large according to the index sequence of the serving cell, wherein the second type power margin is positioned before the first type power margin, and finally obtained information contained in a PHR MAC CE is as follows: type2 PHR of cell 1, type1PHR of cell 1, type2 PHR of cell 2, type1PHR of cell 2, type2 PHR of cell 3, type1PHR of cell 3, type2 PHR of cell 5, type1PHR of cell 5, type2 PHR of cell 6, type1PHR of cell 6, type2 PHR of cell 4, type1PHR of cell 4. Here, the second type power headroom is located before the first type power headroom, which is not limited to this, and the first type power headroom may be located before the second type power headroom.

It should be noted that, in the above solutions, the power headroom types that need to be reported by the cell are type2 PHR and type1PHR, which are taken as examples, but not limited to this, the power headroom types that need to be reported by the cell may also be type2 PHR and type3 PHR, or the power headroom types that need to be reported by the cell are only type1PHR or type3 PHR. Whether type2 PHR exists in each cell depends on the network side configuration and/or the type of the carrier.

It should be noted that, if one or more cells do not need to report the type2 PHR, the rule part (i.e. encapsulation logic) related to the type2 PHR in the first rule may be deleted, and only the rule parts (i.e. encapsulation logic) related to the other types 1PHR or 3 PHR may be reserved.

In the embodiment of the application, the terminal device generates the PHR MAC CE according to the first rule and reports the PHR MAC CE to the network device. The network device also decodes the PHR MAC CE according to the first rule.

In the embodiment of the present application, for a scenario with multiple CGs, if one PHR MAC CE includes PHR of all cells under multiple CGs, the overhead of the PHR MAC CE may be very large. For this reason, a concept of a PHR group (PHR group) is proposed.

In an alternative, the one PHR group includes a set of CGs, and each CG in the set of CGs includes at least one serving cell.

In another alternative, the one PHR group includes a set of serving cells. Further, optionally, in case that the one PHR group includes a group CG, the group CG includes an MCG and at least one SCG.

Here, the network device sends first configuration information to the terminal device, and accordingly, the terminal device receives the first configuration information sent by the network device, where the first configuration information is used to determine the configuration of the PHR group. For example: the network side may configure one or more PHR groups through RRC dedicated signaling, and after receiving the RRC dedicated signaling, the terminal device may determine which serving cells included in the one PHR group are included based on the RRC signaling. For example: the RRC dedicated signaling includes index information of a group of CGs in the PUCCH group or a serving cell index of a group of cells.

Wherein, PHRs of all serving cells in the PHR group are reported in a PHR MAC CE. Specifically, if one cell in one PHR group triggers PHR reporting, the terminal device sends a PHR MAC CE to a network device, where the PHR MAC CE includes the PHR of all the cells in the one PHR group.

In an optional manner, the PHR MAC CE further includes header information, where the header information includes a first bit map, each bit in the first bit map corresponds to one cell in the PHR group, and a value of the bit is used to indicate whether the cell corresponding to the bit reports the corresponding PHR (or indicate whether the PHR of the cell corresponding to the bit is carried in the PHR MAC CE). Here, bits in the first bitmap correspond one-to-one to an order from lower to upper and a sequence from smaller to larger of the serving cell indexes in the one PHR group; or, the bits in the first bitmap correspond to the serving cell indexes in the PHR group in a one-to-one correspondence from low to high.

Then, after the header information, PHR of each cell is sequentially filled in according to a first rule. It should be noted that PHR herein refers to power headroom information in general, and includes at least one of the following: p indication information, V indication information, PHR, P _CMAX,f,c 。

In the embodiment of the present application, in a scenario of multiple SCGs, there may be a scenario of SCG deactivation, and at this time, all serving cells of the SCG do not report the PHR, and the PHR is triggered and reported only in the MCG and the MAC entity activating the SCG. For this, the PHR MAC CE has a header information, where the header information includes a first bit map, each bit in the first bit map corresponds to a cell in a PHR group, and a value of the bit is used to indicate whether the cell corresponding to the bit reports a corresponding PHR. In order to effectively control the size of the PHR MAC CE, the header information of the PHR MAC CE only includes a first bitmap of a PHR group consisting of serving cells activating the SCG and the MCG.

According to the technical scheme of the embodiment of the application, the terminal equipment reports the PHRs of the cells under the CG through the PHR MAC CE, so that the reporting of the PHRs is realized under the scene of multi-CG configuration, the PHR MAC CE is packaged by adopting the first rule, the reporting of the PHRs is more flexible and correct, and the network side can better execute uplink power control and uplink scheduling on the terminal equipment.
