[0143] To facilitate a better understanding of the embodiments of this application, the related technologies are described.

[0144] (1)SSB.

[0145] In order for the UE to search for a suitable cell and synchronize with the selected cell, it is usually necessary to broadcast a synchronization signal and provide some main information about the cell.

[0146] 5th generation (5) th Broadcast signals from Generation 5G (New Radio, NR) systems are transmitted via SSB (Service Subsystem), such as... Figure 2 As shown, the SSB consists of the PSS, SSS, and PBCH. The PSS and SSS are used for signal synchronization, while the PBCH is used to transmit system messages. The PBCH carries the most important system information and is also called the Master Information Block (MIB).

[0147] The SSB consists of 240 consecutive subcarriers (i.e., 20 resource blocks (RBs)) in the frequency domain and four consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain. The PSS is a 127-character sequence mapped onto the first OFDM symbol, occupying the middle 127 subcarriers with 56 and 57 subcarriers on either side that do not transmit any signal. The SSS is also a 127-character sequence located on the third OFDM symbol of the SSB, occupying the middle 127 subcarriers with 8 and 9 subcarriers on either side that do not transmit any signal. The PBCH is located on the second to fourth OFDM symbols of the SSB, with 240 subcarriers each on the second and fourth OFDM symbols and 96 subcarriers on the third OFDM symbol. Therefore, the PBCH has a total of 576 resource elements (REs). The PBCH demodulation reference signal is... The signal (DMRS) occupies 1 / 4 of the resources, so the number of REs occupied by the PBCH payload is 576 * 3 / 4 = 432. Quadrature Phase Shift Keying (QPSK) modulation is used, and the size of the transport block (TB) is 864 bits.

[0148] (2) Channel bandwidth and transmission bandwidth.

[0149] Channel bandwidth refers to the bandwidth of a single RF carrier supported by a 5G base station. NR can support different UE channel bandwidths on the same carrier for sending or receiving signals to or from UEs connected to the base station. For example... Figure 3 As shown, the carrier bandwidth that can be used to transmit data in the channel bandwidth is called the transmission bandwidth. In order to avoid interference between adjacent channels, a certain guard band needs to be reserved at the edge of the channel bandwidth.

[0150] Table 1

[0151]

[0152] As shown in Table 1, different channel bandwidths and subcarrier spacings (SCS) correspond to different maximum transmission bandwidths.

[0153] Table 2

[0154]

[0155] As shown in Table 2, different channel bandwidths and subcarrier spacings correspond to different minimum guard bands.

[0156] It should be understood that “N / A” in Tables 1 and 2 indicates that it is not applicable or there is no data.

[0157] (3) Narrowband terminal.

[0158] To support narrowband terminals, the 4th generation (4G) th The Long Term Evolution (LTE) system (4G) designed a completely new NB-IoT system and a new broadcast signal for it. In version 15, the minimum channel bandwidth defined by the NR system was 5MHz. In order to enable narrowband terminals (such as 3MHz terminals) to access the NR system, in the evolution process of version 18, the method of RB-level pruning of PBCH was determined. That is, the PBCH encoding is still based on 20 RB resources for encoding and resource mapping, the SSB structure remains unchanged, but the receiver only receives the PBCH and PSS / SSS within the middle 3MHz (12 RBs).

[0159] As shown above, the terminal can utilize SSS and PBCH DMRS for joint channel estimation to improve demodulation performance. The EPRE of SSS, PBCH, and PBCH DMRS is the same. This application considers that the SSS design needs to be compatible with both narrowband and wideband terminals. However, for narrowband terminals, PSS only occupies 127 subcarriers, and the remaining subcarrier positions are not occupied by other signals / channels. Therefore, the transmit power of PSS can be improved by 3dB compared to SSS. Furthermore, considering that in 5G networks, to support narrowband terminal access, the terminal can only receive a portion of the PBCH payload, or even if the network side uses a method to increase the PBCH code rate to ensure the narrowband terminal receives the complete PBCH, it will still result in a performance loss of approximately 3dB. Therefore, PBCH coverage enhancement can be performed to ensure the reception performance of narrowband terminals. Additionally, considering that in 6G networks, the terminal may perform rapid beam training during access, the transmit power between different beams can be flexibly controlled.

[0160] In other words, considering the need for 6G SSB design to be compatible with both narrowband and broadband terminals, and the relatively poor reception performance of narrowband SSBs, and the fact that terminals in 6G networks may undergo rapid beam training during access, the transmit power of different beams needs to be flexibly controlled. Therefore, this application provides a method for determining the transmit power of different SSBs or different PSS, SSS, and PBCH within an SSB in various possible scenarios. By flexibly controlling the transmit power, the energy utilization efficiency of the transmit power is improved, thereby ensuring the reception performance of narrowband terminals or ensuring that terminals can quickly and efficiently complete random access.

[0183] For example, the at least one first signal is at least one SSS, the at least one second signal is at least one PSS, and the at least one third signal is at least one PBCH. Of course, the at least one first signal, the at least one second signal, and the at least one third signal can be any three signals capable of forming or constituting a signal group, and this application does not specifically limit them.

[0184] For example, at least two of the at least one first signal, the at least one second signal, and the at least one third signal are associated with or located in the same module. For instance, the at least one first signal is associated with or located in the same module as the at least one second signal, or the at least one first signal is associated with or located in the same module as the at least one third signal, or the at least one second signal is associated with or located in the same module, or the at least one first signal, the at least one second signal, and the at least one third signal are associated with or located in the same module.

[0185] For example, the first signal group is an SSB, and the at least one first signal, the at least one second signal, and the at least one third signal are transmitted within the same SSB.

[0186] For example, the first signal group is a first-level SSB, and the second signal group is a second-level SSB. Alternatively, the first signal group and the second signal group belong to the same SSB set (burst), or the first signal group is an SSB, and the second signal group is the wake-up signal of the SSB. Optionally, the first signal group and the second signal group may be associated with positions on different sync rasters, or there may be a protocol-defined or network-configured frequency interval between the first signal group and the second signal group.

[0187] For example, the time-domain resources of the at least one first signal, the at least one second signal, and the at least one third signal are continuous.

[0188] For example, the at least one power bias can be used for power boosting of at least one of the following: a first signal in the first signal group, a second signal in the first signal group, or a third signal in the first signal group.

[0189] For example, different first signals in the first signal group are associated with independent or identical power configurations, and different first signals in the first signal group are associated with independent or identical power biases.

[0190] For example, the transmission power of the i-th first signal in the first signal group is determined based on the transmission power configured by the power configuration associated with the i-th first signal in the first signal group. For example, the transmission power of the i-th first signal in the first signal group is equal to the transmission power configured by the power configuration associated with the i-th first signal in the first signal group.

[0191] For example, the transmission power of the i-th first signal in the first signal group is determined based on the power bias associated with the i-th first signal in the first signal group. For instance, the transmission power of the i-th first signal in the first signal group is equal to a reference value of the transmission power (e.g., the transmission power agreed upon by the network configuration or protocol, or the transmission power of a specific first signal, or the transmission power of a specific second signal, or the transmission power of a specific third signal) plus its associated power bias.

[0192] For example, each first signal in the first signal group is determined according to the transmission power configured in its associated power configuration. Alternatively, a portion of the first signals in the first signal group are determined according to the transmission power configured in their associated power configuration, and another portion of the first signals in the first signal group are determined according to their associated power bias. Alternatively, each first signal in the first signal group is determined according to its associated power bias.

[0193] For example, different second signals in the first signal group are associated with independent or identical power configurations, and different second signals in the first signal group are associated with independent or identical power biases.

[0194] For example, the transmission power of the i-th second signal in the first signal group is determined based on the transmission power configured by the power configuration associated with the i-th second signal in the first signal group. For example, the transmission power of the i-th second signal in the first signal group is equal to the transmission power configured by the power configuration associated with the i-th second signal in the first signal group.

[0195] For example, the transmission power of the i-th second signal in the first signal group is determined based on the power bias associated with the i-th second signal in the first signal group. For instance, the transmission power of the i-th second signal in the first signal group is equal to a reference value of the transmission power (e.g., the transmission power agreed upon by the network configuration or protocol, or the transmission power of a specific first signal, or the transmission power of a specific second signal, or the transmission power of a specific third signal) plus its associated power bias.

[0196] For example, each second signal in the first signal group is determined according to the transmission power configured in its associated power configuration. Alternatively, a portion of the second signals in the first signal group are determined according to the transmission power configured in their associated power configuration, and another portion of the second signals in the first signal group are determined according to their associated power bias. Alternatively, each second signal in the first signal group is determined according to its associated power bias.

[0197] For example, different third signals in the first signal group are associated with independent or identical power configurations, and different third signals in the first signal group are associated with independent or identical power biases.

[0198] For example, the transmission power of the i-th third signal in the first signal group is determined based on the transmission power configured by the power configuration associated with the i-th third signal in the first signal group. For example, the transmission power of the i-th third signal in the first signal group is equal to the transmission power configured by the power configuration associated with the i-th third signal in the first signal group.

[0199] For example, the transmission power of the i-th third signal in the first signal group is determined based on the power bias associated with the i-th third signal in the first signal group. For instance, the transmission power of the i-th third signal in the first signal group is equal to a reference value of the transmission power (e.g., the transmission power agreed upon by the network configuration or protocol, or the transmission power of a specific first signal, or the transmission power of a specific second signal, or the transmission power of a specific third signal) plus its associated power bias.

[0200] For example, each third signal in the first signal group is determined according to the transmission power configured in its associated power configuration. Alternatively, a portion of the third signals in the first signal group are determined according to the transmission power configured in their associated power configuration, and another portion of the third signals in the first signal group are determined according to their associated power bias. Alternatively, each third signal in the first signal group is determined according to its associated power bias.

[0201] For example, at least one of the following can be agreed upon through network configuration or protocol: whether to increase the transmission power of the first signal in the first signal group, whether to increase the transmission power of the second signal in the first signal group, and whether to increase the transmission power of the third signal in the first signal group. Alternatively, at least one of the following can be agreed upon through network configuration or protocol: whether to decrease the transmission power of the first signal in the first signal group, whether to decrease the transmission power of the second signal in the first signal group, and whether to decrease the transmission power of the third signal in the first signal group. Optionally, the first device can determine the path loss of the first signal, the path loss of the second signal in the first signal group, and the path loss of the third signal in the first signal group based on at least one of the following: the transmission power of the first signal in the first signal group, the transmission power of the second signal in the first signal group, and the transmission power of the third signal in the first signal group.

[0202] In the embodiments of this application, the first signal group received by the first device is associated with at least one of the following: at least one power configuration and at least one power bias, which can improve the flexibility of the transmission power of the first signal group, the first signal in the first signal group, the second signal in the first signal group, or the third signal in the first signal group, thereby improving the energy utilization efficiency of the transmission power of the first signal group, the first signal in the first signal group, the second signal in the first signal group, or the third signal in the first signal group.

[0203] In some embodiments, the at least one power configuration satisfies at least one of the following:

[0204] A specific first signal in the first signal group is associated with an independent power configuration;

[0205] A specific second signal in the first signal group is associated with an independent power configuration;

[0206] A specific third signal in the first signal group is associated with an independent power configuration;

[0207] The at least one first signal is associated with the same power configuration;

[0208] The at least one second signal is associated with the same power configuration;

[0209] The at least one third signal is associated with the same power configuration;

[0210] The power configurations associated with different first signals in the first signal group have different parameters;

[0211] The power configurations associated with different second signals in the first signal group have different parameters;

[0212] The power configurations associated with different third signals in the first signal group have different parameters;

[0213] The parameters configured for the power configuration associated with the first signal group are different from the parameters configured for the power configuration associated with the second signal group.

[0214] For example, one or more first signals in the first signal group can be associated with one power configuration of the at least one power configuration. For instance, all first signals in the first signal group can be associated with one power configuration of the at least one power configuration. One or more second signals in the first signal group can be associated with one power configuration of the at least one power configuration. For instance, all second signals in the first signal group can be associated with one power configuration of the at least one power configuration. One or more third signals in the first signal group can be associated with one power configuration of the at least one power configuration. For instance, all third signals in the first signal group can be associated with one power configuration of the at least one power configuration. One or more signal groups can be associated with one power configuration of the at least one power configuration. In other words, different first signals, different second signals, or different third signals in the first signal group can be associated with independent power configurations, or different first signals, different second signals, or different third signals in the first signal group can be associated with or share a power configuration. One signal group can be associated with an independent power configuration, or multiple signal groups can be associated with or share a power configuration.

[0215] The at least one power configuration and the at least one power bias are described below using the first signal in the first signal group as an example.

[0216] Assuming the first signal group includes two first signals, the at least one power configuration and the at least one power bias can exist in the following ways:

[0217] Method 1: Each of the two first signals is independently associated with one of the at least one power configuration. In other words, the at least one power configuration includes the power configuration associated with each of the two first signals, and the two first signals are not associated with a power bias.

[0218] Method 2: One of the two first signals is associated with one of the at least one power configuration, and the other of the two first signals is associated with one or more power biases. In other words, the at least one power configuration includes the power configuration associated with one of the two first signals, and the at least one power bias includes the power bias associated with the other of the two first signals.

[0219] Method 3: Each of the two first signals is independently associated with one or more power biases. In other words, the at least one power bias includes the power bias associated with each of the two first signals, and the two first signals are not associated with a power configuration.

[0220] For example, assuming the first signal group includes two SSSs, the at least one power configuration and the at least one power bias can exist in the following ways:

[0221] Method 1: Each of the two SSSs is independently associated with one of the at least one power configuration. In other words, the at least one power configuration includes the power configuration associated with each of the two SSSs, and the two SSSs are not associated with power bias.

[0222] Method 2: One of the two SSSs is associated with one of the at least one power configuration, and the other of the two SSSs is associated with one or more power biases. In other words, the at least one power configuration includes the power configuration associated with one of the two SSSs, and the at least one power bias includes the power bias associated with the other of the two SSSs.

[0223] Method 3: Each of the two SSSs is independently associated with one or more power biases. In other words, the at least one power bias includes the power bias associated with each of the two SSSs, and the two SSSs are not associated with a power configuration.

[0224] In this embodiment, by enriching the at least one power configuration, the transmission power of at least one of the first signal group, the first signal in the first signal group, the second signal in the first signal group, or the third signal in the first signal group can be flexibly controlled, which can improve the flexibility of the transmission power of at least one of the first signal group, the first signal in the first signal group, the second signal in the first signal group, or the third signal in the first signal group, and thus improve the energy utilization efficiency of the transmission power of at least one of the first signal group, the first signal in the first signal group, the second signal in the first signal group, or the third signal in the first signal group.

[0225] In some embodiments, the transmission power of the i-th fourth signal in the first signal group is agreed upon by a protocol or configured by a second device, or

[0226] The transmission power of the i-th fourth signal in the first signal group is determined based on at least one of the following: the transmission power of a specific fourth signal in the first signal group; the power bias between the specific fourth signal in the first signal group and the i-th fourth signal in the first signal group; the transmission power of a specific fifth signal in the first signal group; the power bias between the specific fifth signal in the first signal group and the i-th fourth signal in the first signal group; and the power bias between the specific fifth signal in the first signal group and the specific fourth signal in the first signal group. Wherein, the fourth signal includes a first signal among the at least one first signal, and the fifth signal includes a second signal among the at least one second signal or a third signal among the at least one third signal; or the fourth signal includes a second signal among the at least one second signal, and the fifth signal includes a first signal among the at least one first signal or a third signal among the at least one third signal; or the fourth signal includes a third signal among the at least one third signal, and the fifth signal includes a first signal among the at least one first signal or a second signal among the at least one second signal.

[0227] For example, the at least one power configuration includes at least one of the following: a power configuration for configuring the transmission power of a specific fourth signal in the first signal group, and a power configuration for configuring the transmission power of a specific fifth signal in the first signal group. The at least one power bias includes at least one of the following: a power bias between the specific fourth signal in the first signal group and the i-th fourth signal in the first signal group, a power bias between the specific fifth signal in the first signal group and the i-th fourth signal in the first signal group, and a power bias between the specific fifth signal in the first signal group and the specific fourth signal in the first signal group.

[0228] For example, the power bias between a specific fifth signal in the first signal group and a specific fourth signal in the first signal group includes at least one of the following: the power bias between a specific first signal in the first signal group and a specific second signal in the first signal group, the power bias between a specific first signal in the first signal group and a specific third signal in the first signal group, and the power bias between a specific second signal in the first signal group and a specific third signal in the first signal group.

[0229] For example, a specific fifth signal in the first signal group can be a fifth signal at a specific position in the first signal group, such as the first fifth signal, the last fifth signal, a fifth signal in the middle position, or a fifth signal at another position in the first signal group. The specific fifth signal in the first signal group can be agreed upon by a protocol or indicated by a second device. Similarly, a specific fourth signal in the first signal group can be a fourth signal at a specific position in the first signal group, such as the first fourth signal, the last fourth signal, a fourth signal in the middle position, or a fourth signal at another position in the first signal group. The specific fourth signal in the first signal group can be agreed upon by a protocol or indicated by a second device.

[0230] For example, the transmission power of the i-th first signal in the first signal group is determined according to at least one of the following:

[0231] The transmission power of a specific first signal in the first signal group; the power bias between a specific first signal in the first signal group and the i-th first signal in the first signal group; the transmission power of a specific second signal in the first signal group; the power bias between a specific second signal in the first signal group and the i-th first signal in the first signal group; the power bias between a specific second signal in the first signal group and the specific first signal in the first signal group; the transmission power of a specific third signal in the first signal group; the power bias between a specific third signal in the first signal group and the i-th first signal in the first signal group; the power bias between a specific third signal in the first signal group and the specific first signal in the first signal group; the power bias between a specific third signal in the first signal group and the specific second signal in the first signal group. The specific third signal in the first signal group can be a third signal at a specific position in the first signal group, such as the first third signal, the last third signal, a third signal in the middle position, or a third signal at other positions in the first signal group. The specific third signal in the first signal group can be agreed upon by a protocol or indicated by a second device. The specific second signal in the first signal group can be the second signal at a specific position in the first signal group, such as the first second signal, the last second signal, the second signal at the middle position, or the second signal at other positions in the first signal group. The specific second signal in the first signal group can be agreed upon by a protocol or indicated by a second device.

[0232] For example, the transmission power of the i-th first signal in the first signal group is determined according to at least one of the following:

[0233] 1. The transmission power of a specific first signal in the first signal group, and the power bias between the specific first signal in the first signal group and the i-th first signal in the first signal group;

[0234] 2. The transmission power of a specific second signal in the first signal group, and the power bias between the specific second signal in the first signal group and the i-th first signal in the first signal group;

[0240] For example, the transmission power of the i-th second signal in the first signal group is determined according to at least one of the following:

[0241] The transmission power of a specific second signal in the first signal group; the power bias between a specific second signal in the first signal group and the i-th second signal in the first signal group; the transmission power of a specific first signal in the first signal group; the power bias between a specific first signal in the first signal group and the i-th second signal in the first signal group; the power bias between a specific first signal in the first signal group and the specific second signal in the first signal group; the transmission power of a specific third signal in the first signal group; the power bias between a specific third signal in the first signal group and the i-th second signal in the first signal group; the power bias between a specific third signal in the first signal group and the specific second signal in the first signal group; the power bias between a specific first signal in the first signal group and the specific third signal in the first signal group. Wherein, the specific first signal in the first signal group can be a first signal at a specific position in the first signal group, such as the first first signal, the last first signal, a first signal at an intermediate position, or a first signal at another position in the first signal group. The specific first signal in the first signal group can be agreed upon by a protocol or indicated by a second device. The specific third signal in the first signal group can be a third signal at a specific position in the first signal group, such as the first third signal, the last third signal, the third signal at the middle position, or the third signal at other positions in the first signal group.

[0242] For example, the transmission power of the i-th second signal in the first signal group is determined according to at least one of the following:

[0243] 1. The transmission power of a specific second signal in the first signal group, and the power bias between the specific second signal in the first signal group and the i-th second signal in the first signal group;

The specific second signal in the first signal group can be agreed upon by a protocol or indicated by a second device.

[0252] For example, the transmission power of the i-th third signal in the first signal group is determined according to at least one of the following:

[0253] 1. The transmission power of a specific third signal in the first signal group, and the power bias between the specific third signal in the first signal group and the i-th third signal in the first signal group;

[0254] 2. The transmission power of a specific first signal in the first signal group, and the power bias of the specific first signal in the first signal group and the i-th third signal in the first signal group;

[0260] In this embodiment of the application, by using at least one of a specific first signal, a specific second signal, and a specific third signal in the first signal group and a power bias associated with the corresponding signal, the transmission power of at least one of the first signal, the second signal, and the third signal in the first signal group can be flexibly controlled, thereby improving the flexibility of the transmission power of the first signal in the first signal group and thus improving the energy utilization efficiency of the first signal in the first signal group.

[0261] In some embodiments, the first signal group satisfies at least one of the following:

[0262] The time-domain resources occupied by the first signal, the second signal, and the third signal in the first signal group are continuous;

[0263] Different first signals in the first signal group are associated with the same or different beam or quasi-co-located QCL signals;

[0264] The different first signals in the first signal group are time-division multiplexed (TDM) or frequency-division multiplexed (FDM);

[0265] Different third signals in the first signal group are associated with the same or different reference signal ports or reference signal sequences;

[0266] Different third signals in the first signal group carry the same or different system messages;

[0267] The sub-blocks containing different first signals in the first signal group are time-division multiplexed (TDM) or frequency-division multiplexed (FDM).

[0268] For example, the different third signals in the first signal group, associated with the same or different reference signal ports or reference signal sequences, can be understood or replaced as: the third signals in the sub-blocks containing different first signals in the first signal group, associated with the same or different reference signal ports or reference signal sequences. Optionally, a sub-block includes one of the at least one first signal and one or more of the at least one third signal. Optionally, the reference signal port may be a DMRS port.

[0269] For example, different third signals in the first signal group carry the same or different system messages, including at least one of the following: different third signals in the first signal group carry the same or different PBCH loads; different third signals in the first signal group carry the same or different MIBs.

[0270] The structure of the first signal group will be illustrated below using SSB as an example.

[0271] In some embodiments, considering a narrowband SSB structure, the PBCH payload, which would normally be transmitted within 20 RBs, is transmitted in the narrowband by increasing the bit rate, to ensure that the first device can receive the complete PBCH payload.

[0272] For example, such as Figure 5 As shown, when the transmission bandwidth occupied by the PBCH is limited to 12 RBs, the PBCH no longer multiplexes the same symbol with the SSS. This means that the PBCH can be power-up boosted to improve its decoding performance. Figure 5 (a) contains one first signal (e.g., SSS), one second signal (e.g., PSS), and one third signal (e.g., PBCH). Figure 5 (b) contains one first signal (e.g., SSS), one second signal (e.g., PSS), and two third signals (e.g., PBCH). The first third signal carries the necessary system messages for the low-power first device to access, and the second third signal carries additional system messages for the broadband first device; or the first third signal carries the necessary system messages, and the second third signal carries messages about certain new features, such as NTN ephemeris.

[0273] In some embodiments, the structure of an SSB is considered to be extended to multiple symbols. The same SSB may include multiple SSSs, each SSS occupies one symbol, and the PBCH within the same SSB occupies multiple symbols.

[0274] For example, such as Figure 6 As shown, Figure 6 (a) contains two first signals (e.g., SSS), one second signal (e.g., PSS), and one third signal (e.g., PBCH). The two first signals belong to the same SSB 0, but their powers may be different. Figure 6 (b) includes two first signals (e.g., SSS), one second signal (e.g., PSS), and one third signal (e.g., PBCH). The two first signals are transmitted by wide and narrow beams, respectively. The first device can perform beam training by measuring the signal quality of the two first signals to determine the beam direction with the best signal quality, but they belong to the same SSB. For signal power control, in this scenario, there is a power offset between the two first signals. The PBCH can also have a power offset relative to one of the two first signals, for example, the PBCH can have a power offset relative to either the first or the second of the two first signals. Furthermore, in this scenario, because the power of the two first signals is related to the beam measurement, the first device can report at least one of the following: the beam selected by the first device, and the transmission power associated with the beam selected by the first device.

[0275] In some embodiments, the structure of an SSB is considered to be extended to multiple symbols. The same SSB may include multiple SSSs, each SSS occupying one symbol, and the same SSB may include multiple PBCHs, each PBCH occupying multiple symbols.

[0276] like Figure 7 As shown, the structure of SSB is similar to Figure 6 Similar, but different in that the SSB beam contains multiple third signals, such as Figure 7 As shown in (a) or (b), the contents of multiple third signals may be the same or different, and their power may be different. Similarly, the first third signal carries the necessary system messages for the low-power first device to access, and the second third signal carries additional system messages for the broadband first device; or the first third signal carries the necessary system messages, and the second third signal carries messages of certain new features, such as NTN ephemeris, etc.

[0277] It should be understood that Figures 5 to 7 The structure of the SSB shown is merely an example of this application and should not be construed as a limitation thereof. For example, this application does not specifically limit the relative positional relationship of the first signal, the second signal, and the third signal.

[0278] In this embodiment, when different first signals in the first signal group are associated with different beams or QCL signals, the first device can perform rapid beam training during the access period, thereby improving the beam training effect. Furthermore, when different third signals in the first signal group are associated with the same or different reference signal ports or reference signal sequences, or when different third signals in the first signal group carry the same or different system messages, the receiving performance of the third signals in the first signal group can be guaranteed, or more information can be carried.

[0279] In some embodiments, the transmission power of the j-th sixth signal in the first signal group is agreed upon by a protocol or configured by a second device, or the transmission power of the j-th sixth signal in the first signal group is determined based on at least one of the following: the transmission power of the j-th sixth signal in the second signal group; the power bias between the j-th sixth signal in the second signal group and the j-th sixth signal in the first signal group; the transmission power of a specific sixth signal in the second signal group; the power bias between a specific sixth signal in the second signal group and the j-th sixth signal in the first signal group; the power bias between a specific sixth signal in the second signal group and the j-th sixth signal in the second signal group; the power bias between a specific sixth signal in the second signal group and the specific sixth signal in the first signal group; the power bias between a specific sixth signal in the first signal group and the j-th sixth signal in the first signal group; wherein, the sixth signal includes one of the following: a first signal among the at least one first signal, a second signal among the at least one second signal, and a third signal among the at least one third signal.

[0280] For example, the at least one power configuration includes at least one of the following: a power configuration for configuring the transmission power of the j-th sixth signal in the second signal group, and a power configuration for configuring the transmission power of a specific sixth signal in the second signal group. The at least one power bias includes at least one of the following: a power bias between the j-th sixth signal in the second signal group and the j-th sixth signal in the first signal group, a power bias between a specific sixth signal in the second signal group and the j-th sixth signal in the first signal group, a power bias between a specific sixth signal in the second signal group and the j-th sixth signal in the second signal group, a power bias between a specific sixth signal in the second signal group and the specific sixth signal in the first signal group, and a power bias between a specific sixth signal in the first signal group and the j-th sixth signal in the first signal group.

[0281] It should be noted that, in other alternative embodiments, the transmission power of the first signal in the first signal group, the transmission power of the second signal in the first signal group, or the transmission power of the third signal in the first signal group can be determined based on at least one of the following: the power bias between the first signal in the first signal group and the second signal in the second signal group, the power bias between the first signal in the first signal group and the third signal in the second signal group, the power bias between the second signal in the first signal group and the first signal in the second signal group, the power bias between the second signal in the first signal group and the third signal in the second signal group, the power bias between the third signal in the first signal group and the first signal in the second signal group, the power bias between the third signal in the first signal group and the second signal in the second signal group, one of the first signal in the first signal group, the second signal in the first signal group, and the power bias between the first signal in the second signal group, the second signal in the second signal group, and the third signal in the second signal group. This application does not specifically limit this.

[0282] For example, the transmission power of the j-th first signal in the first signal group is determined according to at least one of the following:

[0283] The transmission power of the j-th first signal in the second signal group; the power bias between the j-th first signal in the second signal group and the j-th first signal in the first signal group; the transmission power of a specific first signal in the second signal group; the power bias between the specific first signal in the second signal group and the j-th first signal in the first signal group; the power bias between the specific first signal in the second signal group and the j-th first signal in the second signal group; the power bias between the specific first signal in the second signal group and the specific first signal in the first signal group; the power bias between the specific first signal in the first signal group and the j-th first signal in the first signal group.

[0284] For example, the transmission power of the j-th first signal in the first signal group is determined according to at least one of the following:

[0285] 1. The transmission power of the j-th first signal in the second signal group, and the power bias between the j-th first signal in the second signal group and the j-th first signal in the first signal group;

[0286] 2. The transmission power of a specific first signal in the second signal group, and the power bias between the specific first signal in the second signal group and the j-th first signal in the first signal group;

[0287] 3. The transmission power of a specific first signal in the second signal group, the power bias between the specific first signal in the second signal group and the j-th first signal in the second signal group, and the power bias between the j-th first signal in the second signal group and the j-th first signal in the first signal group;

[0288] 4. The transmission power of a specific first signal in the second signal group, the power bias between a specific first signal in the second signal group and a specific first signal in the first signal group, and the power bias between a specific first signal in the first signal group and the j-th first signal in the first signal group.

[0289] It should be noted that the transmission power of the j-th first signal in the first signal group can be determined based on the transmission power of the p-th first signal in the second signal group and the related power bias. In other words, in this application, the transmission power of the j-th first signal in the first signal group can be determined based on the first signal in the second signal group whose position (or signal index) is different from that of the j-th first signal in the first signal group. For example, when the number of first signals in the first signal group is different from the number of first signals in the second signal group, the transmission power of the j-th first signal in the first signal group can be determined based on the transmission power of the p-th first signal in the second signal group and the related power bias.

[0290] For example, the transmission power of the j-th second signal in the first signal group is determined according to at least one of the following:

[0291] The transmission power of the j-th second signal in the second signal group; the power bias between the j-th second signal in the second signal group and the j-th second signal in the first signal group; the transmission power of a specific second signal in the second signal group; the power bias between a specific second signal in the second signal group and the j-th second signal in the first signal group; the power bias between a specific second signal in the second signal group and the j-th second signal in the second signal group; the power bias between a specific second signal in the second signal group and a specific second signal in the first signal group; the power bias between a specific second signal in the first signal group and the j-th second signal in the first signal group.

[0292] For example, the transmission power of the j-th second signal in the first signal group is determined according to at least one of the following:

[0293] 1. The transmission power of the j-th second signal in the second signal group, and the power bias between the j-th second signal in the second signal group and the j-th second signal in the first signal group;

[0294] 2. The transmission power of a specific second signal in the second signal group, and the power bias between the specific second signal in the second signal group and the j-th second signal in the first signal group;

[0295] 3. The transmission power of a specific second signal in the second signal group, the power bias between the specific second signal in the second signal group and the j-th second signal in the second signal group, and the power bias between the j-th second signal in the second signal group and the j-th second signal in the first signal group;

[0296] 4. The transmission power of a specific second signal in the second signal group, the power bias between the specific second signal in the second signal group and the specific second signal in the first signal group, and the power bias between the specific second signal in the first signal group and the j-th second signal in the first signal group.

[0297] It should be noted that the transmission power of the j-th second signal in the first signal group can be determined based on the transmission power of the p-th second signal in the second signal group and the associated power bias. In other words, in this application, the transmission power of the j-th second signal in the first signal group can be determined based on a second signal in the second signal group whose position (or signal index) differs from that of the j-th second signal in the first signal group. For example, when the number of second signals in the first signal group is different from the number of second signals in the second signal group, the transmission power of the j-th second signal in the first signal group can be determined based on the transmission power of the p-th second signal in the second signal group and the associated power bias.

[0298] For example, the transmission power of the j-th third signal in the first signal group is determined according to at least one of the following:

[0299] The transmission power of the j-th third signal in the second signal group; the power bias between the j-th third signal in the second signal group and the j-th third signal in the first signal group; the transmission power of a specific third signal in the second signal group; the power bias between the specific third signal in the second signal group and the j-th third signal in the first signal group; the power bias between the specific third signal in the second signal group and the j-th third signal in the second signal group; the power bias between the specific third signal in the second signal group and the specific third signal in the first signal group; the power bias between the specific third signal in the first signal group and the j-th third signal in the first signal group.

[0300] For example, the transmission power of the j-th third signal in the first signal group is determined according to at least one of the following:

[0301] 1. The transmission power of the j-th third signal in the second signal group, and the power bias between the j-th third signal in the second signal group and the j-th third signal in the first signal group;

[0302] 2. The transmission power of a specific third signal in the second signal group, and the power bias between the specific third signal in the second signal group and the j-th third signal in the first signal group;

[0303] 3. The transmission power of a specific third signal in the second signal group, the power bias between the specific third signal in the second signal group and the j-th third signal in the second signal group, and the power bias between the j-th third signal in the second signal group and the j-th third signal in the first signal group;

[0304] 4. The transmission power of a specific third signal in the second signal group, the power bias between the specific third signal in the second signal group and the specific third signal in the first signal group, and the power bias between the specific third signal in the first signal group and the j-th third signal in the first signal group.

[0305] It should be noted that the transmission power of the j-th third signal in the first signal group can be determined based on the transmission power of the p-th third signal in the second signal group and the related power bias. In other words, in this application, the transmission power of the j-th third signal in the first signal group can be determined based on a third signal in the second signal group whose position (or signal index) differs from that of the j-th third signal in the first signal group. For example, when the number of third signals in the first signal group is different from the number of third signals in the second signal group, the transmission power of the j-th third signal in the first signal group can be determined based on the transmission power of the p-th third signal in the second signal group and the related power bias.

[0306] In this embodiment of the application, the transmission power of at least one of the first signal, the second signal, and the third signal in the second signal group can be flexibly controlled by at least one of the first signal, the second signal, and the third signal in the first signal group. This can improve the flexibility of the transmission power of the first signal, the second signal, or the third signal in the first signal group, and thus improve the energy utilization efficiency of the transmission power of the first signal, the second signal, or the third signal in the first signal group.

[0307] In some embodiments, the first signal group satisfies at least one of the following:

[0308] The time-domain resources occupied by the first signal group and the second signal group are continuous;

[0309] The first signal group and the second signal group are time-division multiplexed (TDM) or frequency-division multiplexed (FDM);

[0310] The second signal in the first signal group is multiplexed from the second signal in the second signal group;

[0311] The first signal in the first signal group and the first signal in the second signal group are associated with different beam or quasi-co-located QCL signals;

[0312] The reference signal port or reference signal sequence associated with the third signal in the first signal group is used to indicate the beam or quasi-co-located QCL signal associated with the first signal in the first signal group;

[0313] The reference signal port or reference signal sequence associated with the third signal in the second signal group is used to indicate the beam or quasi-co-located QCL signal associated with the first signal in the second signal group;

[0314] The third signal in the first signal group and the third signal in the second signal group are associated with the same reference signal port or reference signal sequence;

[0315] The third signal in the first signal group and the third signal in the second signal group are associated with the same or different beam or quasi-co-located QCL signals.

[0316] The following example illustrates the structure of the SSB set (burst) formed by the first signal group and the second signal group, using the first signal group as an example.

[0317] In some embodiments, the structure of a 6G SSB is considered to extend to multiple symbols. A single SSB includes multiple SSSs, each occupying one symbol. A single SSB also includes one or more PBCHs, each occupying multiple symbols. Furthermore, in this scenario, the MIB message can be identical for different SSBs, differing only in the beam indicated by the PBCH. If the PBCH occupies multiple symbols, the beam can be indicated not through the PBCH payload, but through the PBCH DMRS sequence. Therefore, the PBCH can be repeated on these symbols, or the same PBCH can be transmitted at a lower code rate.

[0318] For example, beams can be distinguished by SSB indexes. Different SSB indices correspond to different SSB structures, and different SSB structures can be used for different scenarios. Alternatively, different SSB index groups or SSB bursts can use different SSB structures. The SSB structure can be a block containing one or more first signals, second signals, and third signals. When the SSB structure includes multiple first signals, different first signals can use the same or different beams.

[0319] For example, such as Figure 8 As shown, the two first signals are transmitted using different beams. The PBCH DMRS sequence index occupying the first two symbols can be used to indicate the SSB index of the first first signal transmission, and the PBCH DMRS sequence index occupying the last two symbols can be used to indicate the SSB index of the second first signal transmission. The content of the third signal transmission in the first signal group can be as follows: Figure 8 As shown in (a) above, the first signal group includes a third signal that occupies 4 symbols and is used to transmit the MIB, or as shown below. Figure 8 As shown in (b) above, the first signal group includes two third signals, which occupy four symbols but are repeated twice, using the same beam transmission, or as shown below. Figure 8 As shown in (c), the first signal group includes two third signals, which occupy 4 symbols, are repeated twice, but are transmitted using different beams.

[0320] It should be understood that Figure 8 The structure of the SSB set shown is merely an example of this application and should not be construed as a limitation thereof. For example, this application does not specifically limit the relative positional relationship of the first signal, the second signal, and the third signal.

[0321] In this embodiment, when the second signal in the first signal group reuses the second signal in the second signal group, resource overhead can be reduced. When the first signal in the first signal group and the first signal in the second signal group are associated with different beams or QCL signals, the first device can perform fast beam training during access, thereby improving the beam training effect. When the reference signal port or reference signal sequence associated with the third signal in the first signal group is used to indicate the beam or QCL signal associated with the first signal in the first signal group; or when the reference signal port or reference signal sequence associated with the third signal in the second signal group is used to indicate the beam or QCL signal associated with the first signal in the second signal group, signaling overhead can be reduced. Furthermore, when the third signal in the first signal group and the third signal in the second signal group are associated with the same reference signal port or reference signal sequence, or when the third signal in the first signal group and the third signal in the second signal group are associated with the same or different beams or QCL signals, the reception performance of the third signal in the first signal or the ability to carry more information can be guaranteed.

[0322] In some embodiments, the at least one power bias is agreed upon via a protocol or configured by a second device, or

[0323] The at least one power bias is determined according to at least one of the following:

[0324] The power bias or power bias index specified in the protocol;

[0325] The power bias or power bias index indicated by the second device;

[0326] The frequency band in which the first signal group is located;

[0327] Subcarrier spacing of the first signal group

[0328] The bandwidth of the first signal group;

[0329] The network type of the network accessed by the first device; for example, the network type of the network accessed by the first device may be TN, NTN or other types;

[0330] The cell type accessed by the first device; for example, the cell type accessed by the first device includes, but is not limited to: coverage cell, capacity cell, energy-saving cell, ordinary cell or other cell types;

[0331] Synchronization grid of the first signal group;

[0332] The period of the first signal group;

[0333] Whether the first signal group is requested or sent on demand.

[0334] For example, the terminal may first determine the at least one power bias, and then determine the transmission power of the i-th fourth signal in the first signal group based on the at least one power bias, or determine the transmission power of the j-th sixth signal in the first signal group based on the at least one power bias. In other words, the at least one power bias may include determining the transmission power of the i-th fourth signal in the first signal group as described above. For example, the at least one power bias includes, but is not limited to, the following power biases mentioned above: the power bias between a specific fourth signal in the first signal group and the i-th fourth signal in the first signal group; the power bias between a specific fifth signal in the first signal group and the i-th fourth signal in the first signal group; and the power bias between a specific fifth signal in the first signal group and a specific fourth signal in the first signal group. Alternatively, the at least one power bias may include various power biases involved in determining the transmission power of the j-th sixth signal in the first signal group as described above. For example, the at least one power bias includes, but is not limited to, the following power biases mentioned above: the power bias between the j-th sixth signal in the second signal group and the j-th sixth signal in the first signal group; the power bias between a specific sixth signal in the second signal group and the j-th sixth signal in the first signal group; the power bias between a specific sixth signal in the second signal group and the j-th sixth signal in the second signal group; the power bias between a specific sixth signal in the second signal group and a specific sixth signal in the first signal group; and the power bias between a specific sixth signal in the first signal group and the j-th sixth signal in the first signal group. This application does not specifically limit this.

[0335] In this embodiment, by enriching the factors used to determine the at least one power bias, the flexibility in determining the transmission power of the first signal group can be further improved, thereby improving the energy utilization efficiency of the transmission power of the first signal group.

[0336] In some embodiments, the transmission power of the k-th seventh signal in the first signal group is agreed upon by a protocol or configured by a second device, or

[0337] The transmission power of the k-th seventh signal in the first signal group is determined according to at least one of the following:

[0338] 1. The transmit power index or power bias index indicated by at least one of the second signal group, the kth seventh signal in the second signal group, and the eighth signal in the second signal group.

[0339] Wherein, the seventh signal includes the first signal among the at least one first signal, and the eighth signal includes the second signal among the at least one second signal or the third signal among the at least one third signal; or the seventh signal includes the second signal among the at least one second signal, and the eighth signal includes the first signal among the at least one first signal or the third signal among the at least one third signal; or the seventh signal includes the third signal among the at least one third signal, and the eighth signal includes the first signal among the at least one first signal or the second signal among the at least one second signal.

[0340] For example, the at least one power configuration is associated with a transmit power index indicated by at least one of the second signal group, the kth seventh signal in the second signal group, and the eighth signal in the second signal group. The at least one power bias is associated with a power bias index indicated by at least one of the second signal group, the kth seventh signal in the second signal group, and the eighth signal in the second signal group.

[0341] For example, the transmit power index or power bias index indicated by at least one of the second signal group, the kth seventh signal in the second signal group, and the eighth signal in the second signal group can be understood or replaced as: the transmit power index or power bias index indicated by at least one of the second signal group, the kth seventh signal in the second signal group, and any eighth signal in the second signal group; or it can be understood or replaced as: the transmit power index or power bias index indicated by at least one of the second signal group, the kth seventh signal in the second signal group, and the eighth signal in the second signal group in the index set agreed upon by the second device configuration or protocol.

[0342] For example, when the seventh signal includes a first signal from the at least one first signal, at least one of the second signal group, the k-th first signal in the second signal group, any second signal in the second signal group, and any third signal in the second signal group can be used to indicate a transmit power index or a power bias index. Similarly, when the seventh signal includes a second signal from the at least one second signal, at least one of the second signal group, the k-th second signal in the second signal group, any first signal in the second signal group, and any third signal in the second signal group can be used to indicate a transmit power index or a power bias index. Furthermore, when the seventh signal includes a third signal from the at least one third signal, at least one of the second signal group, the k-th third signal in the second signal group, any first signal in the second signal group, and any second signal in the second signal group can be used to indicate a transmit power index or a power bias index. Optionally, when the third signal in the second signal group is used to indicate the transmit power index or power bias index, the transmit power index or power bias index can be indicated by the DMRS sequence or sequence index of the third signal in the second signal group, or the third signal in the second signal group can directly carry indication information to indicate the power index or power bias index.

[0343] 2. The time-frequency domain resources of the first signal group and the time-frequency domain resources of the second signal group.

[0344] For example, the transmission power of the k-th seventh signal in the first signal group is determined based on the time-frequency domain resource pattern of the first signal group and the time-frequency domain resource pattern of the second signal group. As one implementation, the transmission power of the k-th seventh signal in the first signal group is determined based on the offset between the time-frequency domain resources of the first signal group and the second signal group. For example, when the first signal group and the second signal group are offset by different symbols / time slots in the time domain, the power offset corresponding to the k-th seventh signal in the first signal group is different.

[0345] 3. The bandwidth of the first signal group and the bandwidth of the second signal group.

[0346] For example, the transmission power or power bias of the k-th seventh signal in the first signal group is determined based on the difference between the bandwidth of the first signal group and the bandwidth of the second signal group. For instance, assuming the difference between the bandwidth of the first signal group and the bandwidth of the second signal group is denoted as D1, the transmission power of the k-th seventh signal in the first signal group is the transmission power corresponding to D1. Furthermore, the transmission power of the k-th seventh signal in the first signal group is determined based on the power bias corresponding to D1.

[0347] 4. The number of synchronization signals associated with the first signal group and the number of synchronization signals associated with the second signal group.

[0348] For example, the transmission power or power bias of the k-th seventh signal in the first signal group is determined based on the difference between the number of synchronization signals associated with the first signal group and the number of synchronization signals associated with the second signal group. For instance, assuming the difference between the number of synchronization signals associated with the first signal group and the number of synchronization signals associated with the second signal group is denoted as D2, the transmission power of the k-th seventh signal in the first signal group is the transmission power corresponding to D2. Furthermore, the transmission power of the k-th seventh signal in the first signal group is determined based on the power bias corresponding to D2.

[0349] 5. The number of reference signal sequences associated with the first signal group and the number of reference signal sequences associated with the second signal group, the number of reference signal ports associated with the first signal group and the number of reference signal ports associated with the second signal group.

[0350] For example, the transmission power or power bias of the k-th seventh signal in the first signal group is determined based on the difference between the number of reference signal sequences associated with the first signal group and the number of reference signal sequences associated with the second signal group, or based on the difference between the number of reference signal ports associated with the first signal group and the number of reference signal ports associated with the second signal group. For instance, assuming the difference between the number of reference signal sequences associated with the first signal group and the number of reference signal sequences associated with the second signal group is used to determine the power, or the difference between the number of reference signal ports associated with the first signal group and the number of reference signal ports associated with the second signal group is denoted as D3, the transmission power of the k-th seventh signal in the first signal group is the transmission power corresponding to D3. Furthermore, the transmission power of the k-th seventh signal in the first signal group is determined based on the power bias corresponding to D3.

[0351] 6. The number of beams associated with the first signal group and the number of beams associated with the second signal group; the number of quasi-co-located QCL signals associated with the first signal group and the number of QCL signals associated with the second signal group.

[0352] For example, the transmission power or power bias of the k-th seventh signal in the first signal group is determined based on the difference between the number of beams associated with the first signal group and the number of beams associated with the second signal group, or based on the difference between the number of QCL signals associated with the first signal group and the number of QCL signals associated with the second signal group. For instance, assuming the difference between the number of beams associated with the first signal group and the number of beams associated with the second signal group, or the difference between the number of QCL signals associated with the first signal group and the number of QCL signals associated with the second signal group, is denoted as D4, the transmission power of the k-th seventh signal in the first signal group is the transmission power corresponding to D4. Furthermore, the transmission power of the k-th seventh signal in the first signal group is determined based on the power bias corresponding to D4.

[0353] 7. Measurement results of the second signal group.

[0354] For example, the measurement results of the second signal group include at least one of the following:

[0355] Beam index, SSB index, adjustment angle, Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal-to-Interference-plus-Noise Ratio (SINR), Peak-to-Average Power Ratio (PAPR), and Error Vector Magnitude (EVM).

[0356] For example, the first device measures the signals in the second signal group to obtain the measurement results of the second signal group.

[0357] For example, the first device reports the measurement results of the second signal group based on the resources configured for the second device.

[0358] The resources configured in the second device include at least one of the following:

[0359] The network device pre-configured resources; resources associated with the second signal group; resources associated with the first signal in the second signal group; resources associated with the second signal in the second signal group; resources associated with or indicated by the third signal in the second signal group. Optionally, in a beam training scenario, beams associated with different first signals in the second signal group can be associated with different resources, or beams associated with different first signals in the second signal group can be associated with different angles, thereby associating with different resources.

[0360] For example, the first device reports the measurement results of the second signal group based on the trigger signal of the first signal group (e.g., the wake-up signal (WUS) of the first signal group) or the signal associated with the first signal group, or the wake-up signal indicated in the second signal group.

[0361] The reporting method for the measurement results of the second signal group includes at least one of the following:

[0362] The measurement results of the second signal group are directly carried in the reporting signal; the measurement results of the second signal group are implicitly indicated by the transmission resources of the reporting signal (e.g., by the time-frequency resources or sequence resources of the reporting signal); the measurement results of the second signal group are indicated by the reference signal of the reporting signal; the measurement results of the second signal group are reported by other signals associated with the reporting signal; the measurement results of the second signal group are indicated by the type of the reporting signal (e.g., different WUS (e.g., WUS sequences) indicate different measurement results).

[0363] 8. The parameters related to the transmission power of the first signal in the first signal group requested by the first device.

[0364] For example, the parameters related to the transmission power of the first signal in the first signal group requested by the first device include, but are not limited to: parameters related to the transmission power of the first signal in the first signal group that the first device expects, and related parameters that affect the transmission power of the first signal in the first signal group requested by the first device. For example, the first device may request parameters related to the transmission power of the first signal in the first signal group on WUS, the trigger signal of the first signal, or the signal associated with the first signal, such as indication information on whether to increase transmission power, the power level expected by the first device, etc.

[0365] For example, the transmission power of the kth seventh signal in the first signal group is determined according to the at least one power bias, which is determined according to at least one of the following:

[0366] The power bias index indicated by at least one of the second signal group, the kth seventh signal in the second signal group, and the eighth signal in the second signal group; the time-frequency domain resources of the first signal group and the second signal group; the bandwidth of the first signal group and the bandwidth of the second signal group; the number of synchronization signals associated with the first signal group and the number of synchronization signals associated with the second signal group; the number of reference signal sequences associated with the first signal group and the number of reference signal sequences associated with the second signal group; the number of reference signal ports associated with the first signal group and the number of reference signal ports associated with the second signal group; the number of beams associated with the first signal group and the number of beams associated with the second signal group; the number of quasi-co-located QCL signals associated with the first signal group and the number of QCL signals associated with the second signal group; the measurement results of the second signal group; and the parameters related to the transmission power of the first signal in the first signal group requested by the first device.

[0367] It should be noted that the power bias index indicated by at least one of the second signal group, the kth seventh signal in the second signal group, and the eighth signal in the second signal group can be the index of various power biases mentioned above, and this application does not specifically limit it.

[0368] In this embodiment of the application, the transmission power of at least one of the first signal, the second signal, and the third signal in the first signal group can be indicated by at least one of the second signal group, the first signal in the second signal group, the second signal in the second signal group, or the third signal in the second signal group. Alternatively, the transmission power of at least one of the first signal, the second signal, and the third signal in the first signal group can be flexibly controlled by the difference between the first signal group and the second signal group, thereby improving the energy utilization efficiency of the transmission power of the first signal, the second signal, or the third signal in the first signal group.

[0369] In some embodiments, the method 200 further includes:

[0370] The first device determines the transmission power of at least one ninth signal based on the transmission power of the third signal in the first signal group;

[0371] The ninth signal includes at least one of the following: a downlink signal and an uplink signal.

[0372] For example, the ninth signal may be a downlink signal, including but not limited to: Channel State Information-Reference Signal (CSI-RS), Physical Downlink Control Channel (PDCCH), Common Search Space, Positioning Reference Signal (PRS), Tracking Reference Signal (TRS), Measurement Reference Signal, Broadcast Channel, Multicast Channel, Random Access Response (RAR), Paging, Msg4, corresponding demodulation reference signal, corresponding control channel, etc.

[0373] For example, the ninth signal may be an uplink signal, including but not limited to: Physical Random Access Channel (PRACH), Msg3 Physical Uplink Shared Channel (PUSCH), MsgAPUSCH, CG PUSCH in RRC idle / inactive state, DG PUSCH in RRC idle / inactive state, SRS (e.g., SRS in RRC inactive / idle state), WUS signal, etc.

[0374] For example, the at least one ninth signal includes a control resource set CORESET0 associated with a third signal in the first signal group.

[0375] In this embodiment, the first device determines the transmission power of at least one ninth signal based on the transmission power of the third signal in the first signal group. This reduces the complexity of determining the transmission power of the ninth signal and also improves the flexibility of the transmission power of the ninth signal, thereby improving the energy utilization efficiency of the transmission power of the ninth signal.

[0376] In some embodiments, the first device determines the transmission power of the at least one ninth signal based on the transmission power of the third signal in the first signal group and the first information:

[0377] The first information includes at least one of the following:

[0378] The correlation between the third signal in the first signal group and the at least one ninth signal;

[0379] The power bias between the third signal in the first signal group and the at least one ninth signal;

[0380] The range of values ​​for the power bias between the third signal and the at least one ninth signal in the first signal group;

[0381] The frequency band in which the at least one ninth signal is located;

[0382] The subcarrier spacing of the at least one ninth signal

[0383] The bandwidth of the at least one ninth signal;

[0384] The network type of the network accessed by the first device; for example, the network type of the network accessed by the first device may be TN, NTN or other types;

[0385] The cell type accessed by the first device; for example, the cell type accessed by the first device includes, but is not limited to: coverage cell, capacity cell, energy-saving cell, ordinary cell or other cell types;

[0386] The synchronization grid of the at least one ninth signal;

[0387] The period of the at least one ninth signal;

[0388] Whether the at least one ninth signal is requested or sent on demand.

[0389] For example, the first device determines the transmission power of the at least one ninth signal based on the association between the third signal in the first signal group and the at least one ninth signal, and at least one of the following: the power bias between the third signal in the first signal group and the at least one ninth signal; the value range of the power bias between the third signal in the first signal group and the at least one ninth signal. For example, when the at least one third signal is N3 third signals and the at least one ninth signal is M CORESET0, the N3 third signals are associated with the M CORESET0, and the power of the m-th CORESET0 among the M CORESET0 is determined by the transmission power of the n-th third signal among the N3 third signals.

[0390] As one implementation method, it can be agreed through a protocol or network that the transmission power of the m-th CORESET0 among the M CORESET0s is determined by the power of the n-th third signal among the N3 third signals. For example, when M = N3, the N3 third signals correspond one-to-one with the M CORESET0s, and their transmission powers also correspond one-to-one. The protocol or network stipulates that the transmission power of the m-th CORESET0 is the same as the transmission power of the third signal corresponding to the m-th CORESET0, or the protocol or network stipulates the power bias between the m-th CORESET0 and the third signal corresponding to the m-th CORESET0, or the protocol or network stipulates the range of values ​​for the power bias between the m-th CORESET0 and the third signal corresponding to the m-th CORESET0; or, the protocol or network stipulates that each CORESET0 in the M CORESET0s corresponds to a specific third signal among the N3, that is, the protocol or network stipulates that the transmission power of each CORESET0 is the same as the transmission power of the specific third signal among the N3, or the protocol or network stipulates the power bias based on the power bias between each CORESET0 and the specific third signal among the N3, or the protocol or network stipulates the range of values ​​for the power bias between each CORESET0 and the specific third signal among the N3.

[0391] As another implementation, the transmission power of the m-th CORESET0 among the M CORESET0s can be configured via the network, based on the power of the n-th third signal among the N3 third signals. For example, the power offset between the m-th CORESET0 and the n-th third signal among the N3 third signals can be configured via the network, or the range of values ​​for the power offset between the m-th CORESET0 and the n-th third signal among the N3 third signals can be configured via the network.

[0392] In this embodiment, by enriching the factors used to determine the at least one power bias, the flexibility in determining the transmission power of the first signal group can be further improved, thereby improving the energy utilization efficiency of the transmission power of the first signal group.

[0393] For example, the first device receives second information before receiving at least one group of signals; wherein the second information includes at least one of the following:

[0394] The at least one power bias;

[0395] The transmission power of one or more first signals in the first signal group;

[0396] The transmission power of one or more second signals in the first signal group;

[0397] The transmission power of one or more third signals in the first signal group.

[0398] In some embodiments, the second information includes the at least one power bias and at least one of the following: the transmission power of the one or more signals; wherein the at least one power bias includes at least one of the following:

[0399] The power bias of each first signal in the first signal group, excluding the one or more first signals;

[0400] The power bias of each of the second signals in the second signal group, excluding the one or more second signals;

[0401] The power bias of each third signal in the first signal group, excluding the one or more third signals.

[0402] For example, when the total number of the at least one first signal, the at least one second signal, and the at least one third signal is N, if the second signal includes the transmission power of an Xth signal, then the at least one power bias includes the power bias of the remaining N-1 Xth signals. For example, the at least one power bias includes the power bias between each Xth signal in the remaining N-1 Xth signals and the Xth signal; or, if the power bias of the remaining N-1 Xth signals is defaulted, then the transmission power of the power bias of the remaining N-1 Xth signals is the same as the transmission power of the Xth signal, where N>1. Optionally, the Xth signal can be one of the following: a first signal in the at least one first signal, a second signal in the at least one second signal, or a third signal in the at least one third signal. Optionally, the remaining N-1 Xth signals include at least one of the following: one or more first signals in the first signal group, one or more second signals in the first signal group, or one or more third signals in the first signal group.

[0403] For example, the second information includes the transmission power of each of the at least one first signal, the transmission power of each of the at least one second signal, and the transmission power of each of the at least one third signal.
