[0218] b. the measured value of P-MPR applied by at least one activated FR2 serving cell has changed by more than phr-Tx-PowerFactorChange dB since the last transmission of PHR on this MAC entity due to the measured value of P-MPR applied being equal to or greater than mpe-Threshold of this MAC entity to meet the FR2 MPE requirement.

[0219] In some embodiments, the terms "reference signal (RS)", "synchronization signal (SS)", "synchronization signal block (SSB)", "pilot", "pilot signal", and the like can be replaced with each other.

[0220] In the Ambient IOT system and the 6G IOT system, the IOT devices (including the Ambient IOT devices and the 6G IOT devices) can access the network in a direct or indirect manner.

[0221] In some embodiments, the IOT devices can access the network in a direct manner. Taking the network access manner of the Ambient IOT devices in the Ambient IOT system as an example, referring to FIG. 2A, FIG. 2A is a schematic diagram of a network architecture, according to an embodiment of the present disclosure, as shown in FIG. 2A, taking the access network device as a base station as an example, the Ambient IOT devices and the base station can directly transmit and receive data (including uplink data and downlink data).

[0222] In some embodiments, the IOT devices can access the network in an indirect manner. Taking the network access manner of the Ambient IOT devices in the Ambient IOT system as an example, referring to FIG. 2B, FIG. 2B is another schematic diagram of a network architecture, according to an embodiment of the present disclosure, taking the access network device as a base station as an example, as shown in FIG. 2B, the Ambient IOT devices and the base station can indirectly transmit and receive data (including uplink data and downlink data), and the intermediate node can play a data forwarding function between the Ambient IOT devices and the base station.

[0223] In some embodiments, the UE can be used as an intermediate node between the IOT devices and the base station.

[0224] In some embodiments, in the New Radio (NR) system, the base station can perform power control on the UE based on the power of the Uu interface signaling transmission. However, in the Ambient IoT system and the 6G IOT system, for the UE as an intermediate node, the power is not only used for the Uu interface signaling transmission, but also used for the Reader to Device (R2D) transmission in the AIoT interface, therefore, in this case, for the UE as an intermediate node, if the power control on the UE is only based on the power of the Uu interface signaling transmission, the power control effect will be poor.

[0283] In some embodiments, the terminal can determine the first power range based on the power consumption of the terminal performing the first operation on the low-power device, to determine the transmission power of the terminal within the first power range.

[0284] In some embodiments, the first power range can consist of a first power range lower limit and a first power range upper limit, and the maximum transmission power of the terminal can be a value between the first power range lower limit and the first power range upper limit. That is, P CMAX_L,f,c ≤ P CMAX,f,c ≤ P CMAX_H,f,c , where P CMAX,f,c is the maximum transmission power of the terminal on the carrier f of the serving cell c, P CMAX_L,f,c is the first power range lower limit, and P CMAX_H,f,c is the first power range upper limit.

[0287] In some embodiments, the determination of the upper limit of the first power range can be achieved by the following formula: P CMAX_H,f,c = MIN{P EMAX,c , P PowerClass - ΔP PowerClass}.

[0288] wherein, P CMAX_H,f,c is the upper limit of the first power range, P EMAX,c is the maximum transmission power limit of the terminal, P PowerClass is the maximum terminal power for shared spectrum access operation, and ΔP PowerClass is the terminal power variation allowed for shared spectrum access operation based on P PowerClass .

[0289] In some embodiments, P EMAX,c may be configured by an information element (IE) for describing the maximum transmission power limit of the device or cell, which may, optionally, be p-Max IE, NR NS PmaxList IE, etc., but is not limited thereto. Taking the case where the IE for describing the maximum transmission power limit of the device or cell is p-Max IE or NR NS PmaxList IE, the configuration of P EMAX,c may be achieved by the additionalPmax field in the p-Max IE or NR NS PmaxList IE.

[0290] In some embodiments, the value of ΔT C,c may be agreed in the protocol, for example, the value of ΔT C,c may be 0 dB or 1.5 dB, and the value of ΔT C,c under different network states may be agreed in the protocol.

[0291] In some embodiments, the value of P PowerClass may be agreed in the protocol.

[0292] In some embodiments, the value of ΔP PowerClass may be agreed in the protocol, for example, different values of ΔP PowerClass may be configured for different network states, different power levels of the terminal, etc.

[0293] In some embodiments, MPRc , ΔMPR c , A-MPR c , and P-MPR c may be agreed by protocol, for example, different MPRs can be configured for different shared spectrum access operations c , ΔMPR c , A-MPR c , and P-MPR c .

[0294] In some embodiments, the value of ΔT IB,c may be agreed by protocol, for example, different ΔT IB,c values can be configured for different terminal operating frequency ranges.

[0295] In some embodiments, the value of ΔT RxSRS may be agreed by protocol, for example, different ΔT RxSRS values can be configured for different SRS TxSwitch capabilities.

[0317] Type W power headroom: the power headroom of the terminal after the SRS transmission and the CW transmission is subtracted from the nominal maximum transmission power.

[0318] In some embodiments, the base station can configure PeriodicTimer and / or phr-ProhibitTimer for the new type of PHR reporting.

[0319] In some embodiments, a new MAC CE can be introduced for PHR to distinguish the PHR type.

[0320] Optionally, an indication field can be added in the PHR MAC CE reporting to indicate the PHR type of the current MAC CE, for example, different values of the R field in the existing PHR MAC CE can be used for indication.
