All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. "and/or" in various embodiments of the present specification means at least one of front and rear.

It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, for example: a Long Term Evolution (LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD) System, a Universal Mobile Telecommunications System (UMTS) or Worldwide Interoperability for Microwave Access (WiMAX) communication System, a 5G System, a New Radio (NR) System, or a subsequent Evolution communication System.

In the embodiment of the present invention, the Terminal device may include, but is not limited to, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a Mobile phone (Mobile Telephone), a User Equipment (UE), a handset (handset), a portable device (portable Equipment), a vehicle (vehicle), etc., and the Terminal device may communicate with one or more core networks through a Radio Access Network (RAN), for example, the Terminal device may be a Mobile phone (or referred to as a "cellular" phone), a computer with a wireless communication function, and the Terminal device may also be a portable, pocket, handheld, computer-embedded, or vehicle-mounted Mobile apparatus.

In the embodiment of the present invention, the network device is a device deployed in a radio access network to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of devices having a base station function may differ. For example, in an LTE network, referred to as an Evolved node B (eNB or eNodeB), in a third Generation (3G) network, referred to as a node B (node B), in a 5G system, referred to as a next Generation node B (gnb), or a network device in a subsequent Evolved communication system, etc., the words are not limited.

As shown in fig. 1, an embodiment of the present invention provides a power reporting method 100, which may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, and the method includes the following steps:

s102: receiving a Multicast Broadcast Service (MBS) message through a Secondary Cell Group (SCG).

S104: and responding to the MBS message, and sending a Physical Uplink Control Channel (PUCCH) through the target cell.

Alternatively, the target Cell may be a Cell within a Master Cell Group (MCG), for example, the target Cell is a Primary Cell (PCell) or a Secondary Cell (SCell) within the MCG. In this example, the SCG may not configure the uplink resource, and the SCG does not have uplink transmission, which is convenient to reduce the consumption of uplink reception of the network device and save resources.

The target Cell may also be a Cell within an SCG, e.g., the target Cell is a Primary Secondary Cell (PSCell) or an SCell within an SCG.

The PUCCH transmitted in this step may be an acknowledgement message (ACK) or a negative acknowledgement message (NACK), which is used to indicate successful reception of the MBS message and unsuccessful reception of the MBS message, respectively.

S106: reporting first Power information of a Type 4PH (PH Type4) or second Power information of a virtual Type 2PH (virtual PH Type2, or referred to as reference Type 2PH) of the target cell when there is no Physical Uplink Shared Channel (PUSCH) transmission on the target cell and a Power Headroom (PH) needs to be reported.

The above type 4PH is used for power information calculation in case of PUCCH-only transmission. For example, the first power information calculated by type 4PH may be obtained by subtracting the transmission power of PUCCH from the uplink maximum transmission power.

In this embodiment, type 4PH is a newly defined power headroom reporting type, and only the transmission power of the PUCCH needs to be calculated, but the transmission power of the PUSCH (usually, the PUSCH is not transmitted) does not need to be calculated. Therefore, other similar terms may be used to denote type4 PH. For example, Type 5PH, Type 6PH, etc. are only required to be distinguishable from PH Type1, PH Type2, and PH Type3 in the related art.

The above-mentioned virtual type 2PH is used for power information calculation by type 2PH without PUSCH transmission. For example, the virtual type 2PH is a transmission power of the PUSCH of the reference format or a transmission power of the PUSCH of 0 power as a transmission power of the PUSCH when there is no PUSCH transmission.

In this embodiment, the virtual type 2PH is power information calculation with reference to the type 2PH without PUSCH transmission. Accordingly, other similar terms may be used to refer to virtual type2 PH. For example, referring to type 2PH and the like, it is sufficient if it can be distinguished from type 2PH in the related art.

Optionally, in this embodiment, the first Power information or the second Power information may be placed in a Power Headroom Report (PHR) Media Access Control-Control Element (MAC CE), and the PHR MAC CE may be sent through an uplink subframe.

In the power reporting method provided by the embodiment of the invention, in a scenario where the SCG only receives MBS messages, the first power information of type 4PH or the second power information of virtual type 2PH can be reported by the target cell, so that the problem that the power information cannot be reported is solved, network equipment can conveniently obtain related power information in time, and the possibility is provided for flexible network deployment of a network, various internet of things and broadcast applications.

The power reporting method provided by the embodiment of the invention can also be applied to non-MBS scenes, for example, the situation of only downlink reception sometimes occurs in the application of the Internet of things, and the power reporting method provided by the embodiment of the invention can also be adopted at this moment.

Optionally, in the embodiment 100, the first power information of type 4PH includes at least one of:

1) the power headroom after the terminal device transmits the PUCCH, for example, type 4PH (PH type4) indicates the power headroom after the terminal device transmits the PUCCH.

2) The terminal device may send the maximum available cell transmit power after sending the PUCCH, for example, the maximum cell transmit power of the cell after sending the PUCCH.

Optionally, in embodiment 100, the first power information of type 4PH is reported by the terminal device when at least one of the following conditions is met:

1) the power headroom report PHR Timer (prohibitPHR-Timer) is prohibited from running, the terminal device obtains uplink resources for new data transmission, and the downlink path loss change exceeds a first threshold, specifically, for example, the prohibitPHR-Timer is overtime, the terminal device has resources for uplink new data transmission, and the path loss change from the last PH information reporting time exceeds an uplink path loss change threshold (dl-pathloss change) dB.

2) The periodic PHR timer times out.

3) The PHR function is configured or reconfigured, for example, a higher layer configuration or a reconfigured PH reporting function (except for a configuration in which PH reporting is prohibited).

It should be noted that the embodiments of the present invention are not limited to the above triggering manners, and other manners capable of triggering the terminal to report the PH may also be applied to the embodiments of the present invention.

In a specific example, the first power information of the target cell type 4PH is calculated by the following formula:

PH _type4,c (i)＝P _CMAX,c (i)-{P _{0_PUCCH} +PL _c +Δ _TF,i }

P _CMAX,c (i)＝MIN{P _EMAX,c ,P _PowerClass -ΔP _PowerClass }

wherein the pH is _type4,c (i) The first power information;

i is the transmission timing of the PUCCH.

P _EMAX,c Is the maximum transmission power of the terminal device.

P _PowerClass The power grade of the terminal equipment can be obtained from a terminal power grade table.

Specifically, for example, the terminal device may be prohibited from reporting the "power information of the SCG cell" through the SCG "by the network device configuration or protocol agreement. In a specific example, the SCG does not configure any PUSCH uplink transmission, and therefore cannot report the PHR MAC CE, the terminal device does not trigger reporting "power information of SCG cell" on the SCG.
