[0184] In some embodiments, power control of a terminal (ie, UE) may be implemented through a Power Headroom Reporting (PHR) procedure.

[0185] In some embodiments, the PHR procedure may be used to provide the following information to the serving gNB:

[0186] (1) Type 1 power headroom: The difference between the nominal maximum transmit power of each UE in the activated serving cell and the estimated power of the uplink shared channel (UL-SCH);

[0187] (2) Type 2 power headroom: the difference between the nominal maximum transmit power of the UE and the estimated power of the UL-SCH and Physical Uplink Control Channel (PUCCH) transmissions on the special cell (SpCell) of another Medium Access Control (MAC) entity, where the other MAC entity can be the Evolved Universal Terrestrial Radio Access (E-UTRA) MAC entity in the case of E-UTRAN New Radio Dual Connectivity (EN-DC), New Radio E-UTRAN Dual Connectivity (NE-DC) and Next Generation RAN E-UTRA New Radio-Dual Connectivity (NGEN-DC);

[0188] (3) Type 3 power headroom: The difference between the nominal maximum transmit power of each UE in the activated serving cell and the estimated power of the Sounding Reference Signal (SRS) transmission;

[0189] (4) MPE P-MPR: To meet the Maximum Permissible Exposure (MPE) requirement of Frequency Range 2 (FR2), power backoff is performed on serving cells operating in FR2.

[0190] In some embodiments, Radio Resource Control (RRC) may control power headroom reporting by configuring the following parameters:

[0191] (1) Periodic timer (phr-PeriodicTimer);

[0192] (2) Prohibit timer (phr-ProhibitTimer);

[0193] (3) Transmission power factor change (phr-Tx-PowerFactorChange);

[0194] (4) Type 2 for other cells (phr-Type2OtherCell);

[0201] (11) MPE resource pool add / modify list (mpe-ResourcePoolToAddModList);

[0202] (12) Dual PHR mode (twoPHRMode).

[0203] In some embodiments, the power headroom report may be triggered when any of the following events occurs:

[0204] The phr-ProhibitTimer expires or has expired, and the path loss of at least one Reference Signal (RS) used as a path loss reference has changed by more than phr-Tx-PowerFactorChange dB, and the downlink bandwidth part (BandwidthPart, BWP) of any active serving cell of this MAC entity is not a dormant BWP since the last PHR was transmitted at this MAC entity;

[0205] phr - PeriodicTimer expires;

[0206] The power headroom reporting function is configured or reconfigured by an upper layer, and the reconfigured power headroom reporting function is not used to disable the power headroom reporting function;

[0207] Activate the Secondary Cell (SCell) of any MAC entity, and the first active downlink bandwidth part identifier (firstActiveDownlinkBWP-Id) in its configured uplink is not set to the dormant BWP;

[0208] Activate the Secondary Cell Group (SCG);

[0209] In addition to SCG being deactivated, a Primary Serving Cell (PSCell) is added;

[0210] The phr-ProhibitTimer expires or has expired when the MAC entity has uplink resources for new transmissions and for any activated serving cell configured for uplink of any MAC entity, the following conditions are met:

[0211] Uplink resources are allocated for transmission; or,

[0212] There is a PUCCH transmission on this cell and the power backoff required for power management has changed by more than phr-Tx-PowerFactorChange dB since the last PHR transmission on this cell;

[0213] Switching from the dormant BWP of the uplink SCell configured by any MAC entity to the non-dormant downlink BWP;

[0214] If mpe-Reporting-FR2 is configured and mpe-ProhibitTimer is not running:

[0215] Since the last PHR transmission at this MAC entity, at least one activated FR2 serving cell has applied a P-MPR measurement value equal to or greater than mpe-Threshold; or,

[0216] Because the applied P-MPR measurement is equal to or greater than the mpe-Threshold for this MAC entity to meet the FR2 MPE requirement, the applied P-MPR measurement for at least one activated FR2 serving cell has changed by more than phr-Tx-PowerFactorChange dB since the last PHR transmitted at this MAC entity. In this case, the PHR is referred to as an "MPE P-MPR report".

[0217] In some embodiments, terms such as "reference signal (RS)", "synchronization signal (SS)", "synchronization signal block (SSB)", "pilot", and "pilot signal" can be used interchangeably.

[0218] In the AmbientIOT system and 6GIOT system, IoT devices (including AmbientIOT devices and 6G IOT devices) can access the network directly or indirectly.

[0219] In some embodiments, the IOT device can access the network in a direct way. Take the network access method of the AmbientIOT device in the AmbientIOT system as an example, see Figure 2A , Figure 2A is a schematic diagram of a network architecture according to an embodiment of the present disclosure, such as Figure 2A As shown, taking the access network device as a base station as an example, data (including uplink data and downlink data) can be directly sent and received between the Ambient IOT device and the base station.

[0220] In some embodiments, IoT devices can access the network indirectly. For example, the network access method of AmbientIOT devices in the AmbientIOT system is shown in Figure 2. Figure 2B , Figure 2B FIG. 1 is another schematic diagram of a network architecture according to an embodiment of the present disclosure, taking a base station as an example. Figure 2B As shown, data (including uplink data and downlink data) can be sent and received indirectly between the Ambient IOT device and the base station, and the intermediate node can play the function of data forwarding between the Ambient IOT device and the base station.

[0221] In some embodiments, the UE may be used as an intermediate node between the IoT device and the base station.

[0222] In some embodiments, in the New Radio (NR) system, the base station can perform power control on the UE based on the power sent by the Uu interface signaling. However, in the Ambient IoT system and the 6G IOT system, for the UE as an intermediate node, power is not only used for signaling transmission of the Uu interface, but also for reader-to-device (R2D) transmission in the AIoT interface. Therefore, in this case, for the UE as an intermediate node, if power control is performed on the UE based only on the power sent by the Uu interface signaling, the power control effect will be poor.

[0223] Figure 3 FIG. 1 is an interactive diagram of a power control method according to an embodiment of the present disclosure. Figure 3 As shown, the embodiment of the present disclosure relates to a power control method, which includes:
