[0026] The following description, in conjunction with the accompanying drawings, details the methods for sending or receiving information provided in the embodiments of this application through some examples and application scenarios.

[0027] like Figure 2 As shown in the figure, this application embodiment provides a method 200 for sending or receiving information. This method can be executed by a terminal. In other words, this method can be executed by software or hardware installed on the terminal. The method includes the following steps.

[0028] S202: The terminal obtains first configuration information, which is related to at least two carriers. The first configuration information includes at least one of the following: information on signal generation or scrambling sequence generation, and power control information.

[0029] The first configuration information is related to at least two carriers. For example, the first configuration information includes power control information for at least two carriers in the first carrier group, and may also include information on signal generation or scrambling sequence generation for at least two carriers in the first carrier group.

[0030] In some embodiments, the at least two carriers are contained in the same carrier group; or, the at least two carriers belong to different carrier groups.

[0031] In this embodiment, for example, the terminal can use at least two carriers within the same carrier group to transmit information related to the random access procedure. For example, the terminal transmits Msg1 on carrier 1 and receives Msg2 on carrier 2, etc., where carrier 1 and carrier 2 belong to the same carrier group.

[0032] In another example of this embodiment, the terminal may use at least two carriers in different carrier groups to send information related to the random access procedure. For example, the terminal may send Msg1 on carrier 1 and receive Msg2 on carrier 2, etc., where the carrier group to which carrier 1 belongs is different from the carrier group to which carrier 2 belongs.

[0033] The first configuration information may include information on signal generation or scrambling sequence generation. For example, the terminal may generate uplink first information based on the information on signal generation or scrambling sequence generation, and may also send the first information to the network-side device. For another example, the terminal may receive downlink first information based on the information on signal generation or scrambling sequence generation, which is beneficial for the terminal to receive the first information correctly.

[0034] The first configuration information may include power control information. For example, the terminal may determine the transmission power of the first information based on the power control information, and then transmit the first information.

[0035] In some embodiments, the first configuration information may further include carrier-related information, such as one or more uplink carrier groups, the uplink carrier group containing one or more uplink carriers; and one or more downlink carrier groups, the downlink carrier group containing one or more downlink carriers. The first configuration information may also include carrier group ID and carrier ID, etc.

[0036] S204: The terminal sends or receives first information on a target carrier based on the first configuration information. The target carrier is included in the at least two carriers. The first information is related to the random access procedure. The target carriers for transmitting at least two different first information are different.

[0037] For example, the terminal transmits first information on a determined uplink target carrier based on the first configuration information; or, for another example, the terminal receives first information on a determined downlink target carrier based on the first configuration information.

[0038] The first information is related to the random access process. For example, the first information may include Msg1, Msg2, Msg3, and Msg4 in a 4-step random access process; the first information may include MsgA and MsgB in a 2-step random access process; the first information may also include system information and other related information of the random access process; the first information may also include messages related to the RRC establishment process.

[0039] In this embodiment, at least two different first information transmissions have different target carriers, for example, such as Figure 3 As shown, Figure 3 Carrier 1, Carrier 2, and Carrier 3 are three different carriers. The terminal ( Figure 3 The UE shown completes synchronization and system message reception operations on carrier 1; it transmits Msg1 on carrier 1, which includes a random access preamble; it receives Msg2 on carrier 2, i.e., it receives a random access response (RAR); and it transmits Msg3 (Msg3 contains Scheduled Transmission) and receives Msg4 (Msg4 contains Contention Resolution) on carrier 3. This multi-carrier random access process allows the terminal to flexibly adjust the transmission carriers, improving communication system performance.

[0040] The information transmission or reception method provided in this application embodiment involves a terminal acquiring first configuration information. This first configuration information is related to at least two carriers and includes at least one of the following: signal generation or scrambling sequence generation information, and power control information. The power control information carried in the first configuration information helps the terminal determine a reasonable transmission power to transmit the first information, improving the success rate of random access and minimizing terminal transmission power while ensuring coverage performance. The signal generation or scrambling sequence generation information carried in the first configuration information helps the terminal accurately transmit or receive the first information on the target carrier, enabling a carrier-based random access process. Furthermore, since the target carriers for at least two different first information transmissions are different, for multi-carrier random access processes, this allows the terminal to flexibly adjust the transmission carrier, improving communication system performance.

[0041] In the various embodiments of this application, the at least two carriers may correspond to different cells, bands, sub-bands, or band width parts (BWP). For example, each carrier may correspond to one cell, and at least two carriers may correspond to at least two cells. Alternatively, at least two carriers may correspond to the same cell. Specifically, a cell may contain multiple frequency domain units that are not contiguous in the frequency domain, and the frequency domain units may be carriers.

[0042] The cells involved in the various embodiments of this application may be equivalent to carriers, for example, a cell contains one carrier; or, they may be equivalent to carrier groups, for example, a cell contains a group of carriers, each carrier may have the same or different physical cell identifiers (PCIs); or, they may be equivalent to multiple frequency domain units, for example, a cell contains multiple frequency domain units that are not contiguous in the frequency domain.

[0043] The following sections will introduce the power control information and the signal generation or scrambling sequence generation information in the first configuration information, starting with the power control information.

[0044] In some embodiments, the power control information is used by the terminal to determine the transmission power of the first information, and the power control information includes at least one of the following: 1) Path loss reference carrier group. For example, the terminal calculates the path loss based on the path loss reference signal (such as the SSB configured in the network) on the path loss reference carrier group. In this embodiment, the path loss calculation is always based on the measurement results of the path loss reference signal on the path loss reference carrier group, and is independent of whether the target carrier is within the path loss reference carrier group.

[0045] 2) The path loss reference carrier can be a path loss reference carrier within a carrier group. For example, the terminal calculates the path loss based on the path loss reference signal (such as the SSB configured in the network) on the path loss reference carrier. In this embodiment, the path loss calculation is always based on the measurement results of the path loss reference signal on the path loss reference carrier, while the target carrier and the path loss reference carrier can be different.

[0046] Optionally, the path loss reference carrier is configured independently for each carrier group. For example, one path loss reference carrier is configured in each carrier group, and the path loss calculation on other carriers in the carrier group is obtained based on the measurement results of the path loss reference signal on the path loss reference carrier, which provides high configuration flexibility.

[0047] 3) Path loss reference signal. This embodiment can configure a path loss reference signal for the terminal, which helps the terminal calculate the path loss and then calculate the transmission power of the first information based on the path loss.

[0048] In this embodiment, the first configuration information can be carried by system messages, Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, or Downlink Control Information (DCI). That is, the aforementioned path loss reference carrier group, path loss reference carrier, or path loss reference signal can be configured by system messages, RRC signaling, MAC signaling, or DCI indication.

[0049] In some embodiments, the method further includes: the terminal determining the power control information based on a first association relationship, wherein the first association relationship includes at least one of the following: an association relationship between uplink carriers and downlink carriers, and an association relationship between uplink carrier groups and downlink carrier groups.

[0050] For example, for each downlink carrier, there exists an uplink carrier that is associated with it, and the terminal determines the path loss reference signal on the downlink carrier based on the association.

[0051] In some embodiments, the power control information includes the number or index of one or more downlink carriers, and offset information associated with each downlink carrier, the offset information including at least one of the following: 1) The power control offset values ​​of one or more uplink carriers associated with the downlink carrier, which can be indicated in the form of a power control offset list.

[0052] In some embodiments, the power control bias value includes at least one of the following: power bias value, road loss compensation coefficient value, and road loss compensation value.

[0053] 2) The target received power of one or more uplink carriers associated with the downlink carrier, which may be indicated in the form of a target received power list.

[0054] 3) The nominal power of one or more uplink carriers associated with the downlink carrier, which can be indicated by a nominal power list.

[0055] For example, the network-side equipment may configure four downlink carriers and three uplink carriers for random access. In this configuration, the network-side equipment will configure a power control offset value and a target received power or nominal power for each downlink carrier relative to each uplink carrier. That is, three power control offset values ​​and three target received powers or three nominal powers will be configured for each downlink carrier, each corresponding to a different uplink carrier.

[0056] Optionally, for uplink carriers with the same frequency as the downlink carrier, the power control offset value, target received power, or nominal power may not be configured.

[0057] Optionally, the network-side equipment will be configured with four lists, that is, each downlink carrier will be configured with a list, and each list may contain three power control offset values, three target received power values, or three nominal power values.

[0058] In some embodiments, the downlink carrier has a different frequency point from or is not a default pairing with one or more uplink carriers associated with it. Alternatively, for each downlink carrier, the power control information does not include the power control offset value, target received power, or nominal power of the uplink carrier that has the same frequency point as or is a default pairing with that downlink carrier.

[0059] In some embodiments, the power control bias value includes at least one of the following: power bias value, road loss compensation coefficient value, and road loss compensation value.

[0060] In some embodiments, the first information is uplink information, including at least one of the following: Physical Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS), Wake Up Signaling (WUS), and Sensing Signal.

[0061] The following section will introduce the information on signal generation or scrambling sequence generation in the first configuration information.

[0062] In some embodiments, the information for signal generation or scrambling sequence generation includes: identification information used for signal generation or scrambling sequence generation.

[0063] In some embodiments, the signal or scrambling sequence includes at least one of the following: 1) A signal or scrambling sequence of at least one uplink carrier or carrier group.

[0064] 2) A signal or scrambling sequence of at least one downlink carrier or carrier group.

[0065] 3) At least one uplink carrier group and downlink carrier group signal or scrambling sequence, for example, the uplink carrier group and its corresponding downlink carrier group use the same identification information, which is used for signal generation or scrambling sequence generation.

[0066] In some embodiments, the identification information includes at least one of the following: carrier group identifier (ID), carrier ID, cell ID, and the index of the carrier within the carrier group. For example, the terminal may generate a signal or scrambling sequence based on one of the following identification information: carrier group ID, carrier group ID and cell ID (e.g., the sum of carrier group ID and cell ID, and so on), cell ID, carrier group ID and N multiplied by the index of the carrier within the carrier group, where the value of N can be configured by the network-side device or determined based on the number of carriers within the carrier group.

[0067] In some embodiments, different carriers within the same carrier group have the same cell ID; or, at least two carriers within the same carrier group have different cell IDs. For example, different carriers within a carrier group may have the same or different cell IDs, which may be PCI, etc.

[0068] In some embodiments, the first information includes at least one of the following: Physical Downlink Control Channel (PDCCH), PUSCH, Physical Downlink Shared Channel (PDSCH), Demodulation Reference Signal (DMRS) for physical channels or signals, PUSCH of message A, Phase Tracking Reference Signal (PTRS), Tracking Reference Signal (TRS), PUCCH, WUS, sensing signal, positioning signal, and sequence-based channels or signals (such as PRACH, SRS).

[0069] To illustrate in detail the information sending or receiving methods provided in the embodiments of this application, the following will describe them in conjunction with several specific embodiments.

[0070] Example 1 This embodiment mainly introduces the generation of correlation signals based on multi-carrier signals.

[0071] In this embodiment, the network-side device can indicate identification information through the first configuration information, which is used for signal generation or scrambling sequence generation.

[0072] The main application scenarios of this embodiment are as follows: Figure 3 As shown, Figure 3 Carrier 1, Carrier 2, and Carrier 3 are three different carriers. The terminal ( Figure 3 The UE shown completes synchronization and system message reception operations on carrier 1; transmits Msg1 on carrier 1, which includes a random access preamble; receives Msg2 on carrier 2, which is a random access response (RAR); and transmits Msg3 (which includes Scheduled Transmission) and receives Msg4 (which includes Contention Resolution) on carrier 3.

[0073] When a terminal performs uplink transmission or downlink reception on different carriers within a carrier group, the network-side equipment can configure the identification information within the carrier group through joint configuration or independent configuration. This identification information is used for signal generation or scrambling sequence generation and may include at least one of the following: carrier group identifier (ID), carrier ID, cell ID, and the carrier's index within the carrier group. Different carriers may have the same or different PCIs; different carrier groups may have the same or different PCIs.

[0074] In one example, the cell IDs carried by the SSBs on different carriers can be different. When configuring the initial access carrier, the network-side device configures one or more carrier groups. The carriers within the carrier group generate signals or scrambling sequences based on the carrier group ID, or generate signals or scrambling sequences based on the carrier group ID and the cell ID, or generate signals or scrambling sequences based on the carrier group ID and the carrier ID.

[0075] In another example, within a carrier group, different SSBs carry the same cell ID. In this case, carriers with the same cell ID can be considered as the same carrier group. Carriers within the carrier group generate signals or generate scrambling sequences through the cell ID.

[0076] The channels and signals (i.e., the first information) to which the signal generation or scrambling sequence generation is applied include: PUSCH, PDCCH, PDSCH, DMRS for PUSCH, DMRS for PDSCH, DMRS for PDCCH, PTRS, TRS; PUCCH; WUS; sensing signals; positioning signals; and other sequence-based channels or signals, such as PRACH. It can also be a channel or signal related to the Ambient Internet of Things (AIoT), including at least one of the following: reflected signal, carrier signal (signal sent from CW node to device node), physical reader to device channel (PRDCH), physical device to reader channel (PDRCH); it can also be a channel or signal related to the sidelink, including at least one of the following: Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), Physical Sidelink Feedback Channel (PSFCH), and the DMRS corresponding to these channels.

[0077] The following example uses the initialization enhancement of the scrambling sequence for the first information in an NR system. It should be noted that future 6G communication systems may also use different sequence initialization formulas, but the identification information related to the cell ID will remain the same. The method for determining it can be described as follows.

[0078] For PDCCH, the initialization of its scrambling sequence is as follows:

[0079] If the upper layer configures the parameter pdcch-DMRS-ScramblingID, then Equal to the high-level configuration value; otherwise, identification information. It is equal to the carrier group ID, or the carrier group ID and the cell ID, or the cell ID, or the carrier group ID and the carrier ID, or the carrier group ID and N multiplied by the carrier's index within the carrier group. The value of N can be configured by the network-side equipment or determined based on the number of carriers within the carrier group.

[0080] For PDSCH, the initialization of its scrambling sequence is as follows:

[0081] If the higher-level configuration includes the parameter dataScramblingIdentityPDSCH, then... Equal to the high-level configuration value; otherwise, identification information. It is equal to the carrier group ID, or the carrier group ID and the cell ID, or the cell ID, or the carrier group ID and the carrier ID, or the carrier group ID and N multiplied by the carrier's index within the carrier group. The value of N can be configured by the network-side equipment or determined based on the number of carriers within the carrier group.

[0082] For PUSCH, the initialization of its scrambling sequence is as follows:

[0083] If the higher-level configuration includes the parameter dataScramblingIdentityPUSCH, then... Equal to the high-level configuration value; otherwise, identification information. It is equal to the carrier group ID, or the carrier group ID and the cell ID, or the cell ID, or the carrier group ID and the carrier ID, or the carrier group ID and N multiplied by the carrier's index within the carrier group. The value of N can be configured by the network-side equipment or determined based on the number of carriers within the carrier group.

[0084] The aforementioned PUSCH can be a PUSCH scheduled based on dynamic scheduling, or a PUSCH used for configured grant transmission. The configured grant includes two types: configured grant type 1, where the uplink transmission grant is provided by the RRC layer, the terminal stores the configuration (such as the first configuration information) and uses it as the granted configuration; and configured grant type 2, where the uplink transmission grant is provided by the PDCCH, and the configuration is stored or cleared according to the activation or deactivation indication of the configuration (such as the first configuration information) based on the Layer 1 Signaling.

[0085] For Msg A PUSCH, the initialization of its scrambling sequence is as follows:

[0086] If the higher-level configuration includes the parameter msgA-DataScramblingIndex, then... Equal to the high-level configuration value; otherwise, identification information. It is equal to the carrier group ID, or the carrier group ID and the cell ID, or the cell ID, or the carrier group ID and the carrier ID, or the carrier group ID and N multiplied by the carrier's index within the carrier group. The value of N can be configured by the network-side equipment or determined based on the number of carriers within the carrier group.

[0087] For DMRS for PDCCH, the sequence is initialized as follows:

[0088] If the upper layer configures the parameter pdcch-DMRS-ScramblingID, then Equal to the high-level configuration value; otherwise, identification information. It is equal to the carrier group ID, or the carrier group ID and the cell ID, or the cell ID, or the carrier group ID and N multiplied by the carrier's index within the carrier group. The value of N can be configured by the network-side equipment or determined based on the number of carriers within the carrier group.

[0089] For DMRS for PDSCH, the sequence is initialized as follows:

[0090] If the upper layer configures the parameter scramblingID (which can be one or two) in DMRS-DownlinkConfig, then the identification information... Equal to the high-level configuration value; otherwise, It is equal to the carrier group ID, or the carrier group ID and the cell ID, or the cell ID, or the carrier group ID and N multiplied by the carrier's index within the carrier group. The value of N can be configured by the network-side equipment or determined based on the number of carriers within the carrier group.

[0091] For DMRS for PUSCH, the sequence is initialized as follows:

[0092] If the upper layer configures the parameter scramblingID (which can be one or two) in DMRS-UplinkConfig, then the identification information... Equal to the high-level configuration value; otherwise, It is equal to the carrier group ID, or the carrier group ID and the cell ID, or the cell ID, or the carrier group ID and N multiplied by the carrier's index within the carrier group. The value of N can be configured by the network-side equipment or determined based on the number of carriers within the carrier group.

[0093] For DMRS for PUCCH, PUCCH can have multiple formats, and DMRS may only be applicable to some formats. An example DMRS sequence initialization is as follows:

[0094] If the upper layer configures the parameter scramblingID0 in the uplink DMRS configuration, then Equal to the high-level configuration value; otherwise, identification information. It is equal to the carrier group ID, or the carrier group ID and the cell ID, or the cell ID, or the carrier group ID and N multiplied by the carrier's index within the carrier group. The value of N can be configured by the network-side equipment or determined based on the number of carriers within the carrier group.

[0095] In addition, optionally, for future 6G systems, the generation of signals such as PRACH, SRS, uplink WUS signals, and sensing signals can be related to carrier group ID and / or cell ID. For example, carrier group ID, or carrier group ID and cell ID, or cell ID, or carrier group ID and N multiplied by the index of the carrier within the carrier group can be one of the parameters when generating the first information.

[0096] In addition, in Embodiment 1, during the initial access process, random access process, or after random access, the terminal can flexibly select the downlink carrier or uplink carrier for transmission from multiple available uplink carriers or available downlink carriers, wherein the available uplink carriers and available downlink carriers can be flexibly paired.

[0097] Considering factors such as the purpose of the carrier, signal multiplexing, and signal differences between carriers, network-side equipment can configure one or more uplink carrier groups and / or downlink carrier groups when configuring uplink carriers and / or downlink carriers for random access. Different carrier groups can have different purposes or characteristics, or carry different information.

[0098] The network provides first configuration information (or random access configuration) through system messages or other RRC signaling, wherein the random access configuration includes one or more uplink carrier groups and / or one or more downlink carrier groups, wherein the uplink carrier group includes one or more uplink carriers and the downlink carrier group includes one or more downlink carriers; the network-side device indicates or the protocol specifies the association between the uplink carrier group and the downlink carrier group.

[0099] In some cases, the network-side device is configured with one or more uplink carrier groups for random access, and uplink information during the random access process is only transmitted on carriers within that carrier group.

[0100] In some cases, the network-side device is configured with one or more downlink carrier groups for random access, and downlink information during the random access process will only be received on carriers within that carrier group.

[0101] In some examples, the network side is configured with an uplink carrier group for PRACH transmission, which contains one or more carriers used for PRACH transmission.

[0102] In some examples, the network side configures an uplink carrier group for non-PRACH, which contains one or more carriers. These carriers are used to transmit uplink signals other than PRACH during random access or before RRC establishment or recovery, such as Msg3, Msg5, RRC setuprequest, RRC Resume request, RRC Reestablishment Request, RRC setup complete, RRC Resume complete, and RRC Reestablishment complete messages.

[0103] In some examples, network-side equipment is configured with one or more synchronization reference downlink carrier groups, which contain one or more carriers, and downlink synchronization between carriers can be multiplexed. For example, the carriers within the carrier group share a set of radio frequency (RF) devices on the base station side. Optionally, within the downlink carrier group, SSB can be transmitted on every carrier, or only on one or a few carriers, to reduce SSB overhead.

[0104] In some examples, the network side is configured with downlink carrier groups where SSBs are associated. These carrier groups contain two or more carriers, and the SSBs within the carrier group are associated. For example, the number of SSBs and the SSB beam pointing can be the same across different carriers. Alternatively, the number of SSBs across different carriers can be different, but the SSB beams on different carriers can be associated. For instance, one SSB on a carrier with fewer SSBs can be associated with multiple SSBs on a carrier with more SSBs.

[0105] In some cases, the downlink carrier group configured by the network-side device has the same SSB beam on different carriers. Optionally, in this case, the network side may transmit the SSB only on a certain carrier in the carrier group.

[0106] Optionally, the same carrier can be configured in different carrier groups. For example, the first carrier can be configured as a PRACH transmit carrier, or it can be configured as a transmit carrier for Msg3 or Msg5.

[0107] Example 2 This embodiment mainly introduces uplink power control. For example, the network-side device can indicate power control information through the first configuration information, and the terminal determines the transmission power of the first uplink information based on the power control information.

[0108] In this embodiment, for randomly accessed terminals, as mentioned above, the terminal will perform uplink transmission or downlink reception on different carriers within the selected carrier group. Since the uplink transmission carrier is dynamically adjusted, the path loss, shadow fading, and other effects on different carriers are not the same. Accordingly, the transmission power of the uplink channel / signal also needs to be dynamically adjusted / determined.

[0109] In NR systems, the downlink carrier is fixed during random access. The uplink transmission uses either an uplink carrier (UL carrier) or a supplementary uplink carrier (SUL carrier) based on the measured signal reception quality of the downlink carrier (such as the RSRP of the SSB). The UL carrier has the same frequency as the downlink carrier. The terminal can calculate the corresponding path loss by using the SSB reception quality of the downlink carrier and the SSB transmission power provided in the system message. Since the uplink carrier and the supplementary uplink carrier have different frequencies, the corresponding path loss is different, which will also affect the determination of the uplink transmission power. The protocol pre-compensates for the path loss between different uplink carriers by configuring different target reception powers for each carrier.

[0110] However, in random access scenarios with dynamically adjusted uplink and downlink carriers, the downlink and uplink transmission carriers are relatively fixed during the random access process. In this mode, different messages during the random access process can be sent through different carriers. Considering the different frequency points of the carriers, this embodiment provides several possible implementation methods for path loss determination and path loss compensation: Implementation method 1: Define a path loss reference carrier / path loss reference cell within the carrier group, and you can also define a path loss reference signal.

[0111] In one embodiment, a path loss reference carrier / path loss reference cell is defined in the downlink carrier group. During the initial access process, the path loss is always calculated based on the path loss reference signal (such as the SSB configured in the network) on the path loss reference carrier.

[0112] In this method, path loss is always calculated based on the measurement results of the path loss reference signal on the path loss reference carrier, regardless of whether the transmission carrier of the downlink message is on the path loss reference carrier.

[0113] Optionally, for different uplink carriers within a carrier group, the network-side equipment can configure different power control offset values, target received power, or nominal power for each uplink carrier. The power control offset values ​​include at least one of the following: power offset value, path loss compensation coefficient value, and path loss compensation value.

[0114] Optionally, the network-side equipment can configure one or more of the following at the granularity of each carrier group: received target power, nominal power, and power control offset value.

[0115] Furthermore, the network-side equipment configures the power control offset value, target received power, and nominal power within the carrier group, or configures these parameters in a granular manner for each carrier. This method is independent of whether a path loss reference cell is defined within the carrier group. That is, when the network-side equipment configures one or more carrier groups, the network side can configure them in a granular manner for each carrier group, or in a granular manner for each carrier within the carrier group.

[0116] It should be noted that carrier groups can be optional; for example, when all carriers belong to the same carrier group, there is no need to define a separate carrier group.

[0117] Implementation Method 2: Define path loss compensation values ​​(or path loss offset values) between different carriers or carrier groups.

[0118] In this second implementation, the network-side device configures path loss compensation values ​​between different carriers or carrier groups. For example, the network-side device configures four downlink carriers and three uplink carriers for random access. In this method, the network-side device configures a path loss compensation value for each downlink carrier and each uplink carrier. That is, three path loss compensation values ​​are configured, corresponding to different uplink carriers; optionally, for uplink carriers with the same frequency, this path loss compensation value may not be configured. Optionally, the network-side device configures a list of four path loss compensation values, that is, this list is configured for each downlink carrier.

[0119] The path loss compensation value is relative to a specific carrier or carrier group, or a specific SSB or SSB group. The path loss compensation value can also be configured at the granularity of each SSB / carrier, or at the granularity of each SSB group / carrier group.

[0120] In this method, the path loss calculation (i.e., the path loss can be calculated based on the above path loss compensation value) can be based on the measurement results of any downlink carrier. To support path loss calculation, the network-side equipment will provide the transmission power of the path loss calculation reference signal on each downlink carrier.

[0121] Implementation method 3: Dynamically adjust / indicate the path loss reference carrier or path loss reference carrier group.

[0122] Compared to implementation method 1, in this method, the path loss reference carrier can be dynamically indicated, or determined based on the scheduling carrier or the downlink data transmission carrier. Correspondingly, the network-side equipment configures path loss compensation values ​​between different uplink and downlink carrier combinations, enabling the determination of path loss in the path loss calculation carrier adjustment scenario, as well as the determination of uplink transmission power.

[0123] Implementation Method 4: Define the path loss compensation coefficient between different carriers or carrier groups.

[0124] In this approach, the network-side equipment configures path loss compensation coefficients between different uplink and downlink carriers. That is, the path loss compensation values ​​in Implementation Method 2 above are replaced with path loss compensation coefficient values, which can be relative to a specific carrier, carrier group, SSB, or SSB group. The path loss compensation coefficient values ​​can also be configured at the granularity of each SSB / carrier, or at the granularity of each SSB group / carrier group.

[0125] In this method, path loss can be calculated based on the measurement results of any downlink carrier. To support path loss calculation, the network-side equipment will also provide the transmission power of each downlink carrier as a reference signal for path loss calculation.

[0126] The uplink channels / signals include: PRACH, PUSCH, PUCCH, and SRS. The following description uses uplink channel / signal power control in an NR system as a basis, and the aforementioned enhancements (configuring different path loss offsets or different compensation coefficients) as examples to illustrate the uplink power control method in the multi-carrier scenario. The uplink power control method provided in this application embodiment can use different power control calculation schemes, such as the power control schemes that may be used in 6G communication systems.

[0127] 1. For PRACH transmission power, the PRACH transmission power is determined according to the following formula:

[0128] Where b represents activating the BWP index, c represents the cell or carrier group, f represents the carrier, and i represents the transmission timing. This represents the path loss compensation coefficient. Different path loss compensation coefficients are configured for different uplink carriers.

[0129] Alternatively, the transmit power of PRACH is determined according to the following formula:

[0130] in, This represents the path loss compensation value between different carriers, for example, the path loss compensation value of the transmission carrier compared to the path loss reference cell.

[0131] 2. For PUSCH transmit power, an exemplary formula for calculating transmit power is as follows:

[0132] in, This represents the path loss compensation value between different carriers, for example, the path loss compensation value of the transmission carrier compared to the path loss reference cell.

[0133] It is the maximum transmit power allowed per carrier.

[0134] It is a network configurable parameter, which can be understood as the target received power.

[0135] It is an estimate of the uplink path loss.

[0136] These are network configurable parameters related to partial path loss compensation.

[0137] μ is related to the subcarrier spacing used for PUSCH transmission.

[0138] This is the number of resource blocks allocated for PUSCH transport.

[0139] It is related to the modulation scheme and channel coding rate used for PUSCH transmission.

[0140] This indicates the reference signal index used for downlink path loss estimation.

[0141] 3. For PUCCH transmission power, an exemplary formula for calculating transmission power is as follows:

[0142] in, This can be understood as the target received power, which is and The sum of, It is an estimate of the uplink path loss. It is related to the PUCCH format. Different PUCCH formats have different configuration values, which reflect the impact of the number of CSI bits of the PUCCH on power. This reflects the impact of different PUCCH transmission formats on transmission power. The adjustment amount for the UE PUCCH transmit power is obtained by mapping the TPC information; This represents the path loss compensation value between different carriers.

[0143] 4. Regarding SRS transmit power. In multi-carrier scenarios, during random access or after connection establishment, the terminal can transmit SRS on one or more uplink carriers.

[0144] An exemplary formula for calculating SRS transmit power is as follows:

[0145] Alternatively, the SRS transmission power can be determined using the following formula:

[0146] in, This represents the path loss compensation value between different carriers. Through higher-layer signaling configuration, the SRS resource set configured on the uplink BWP b on carrier f in cell c corresponds to... The corresponding high-level parameter P0 value, This indicates the number of frequency domain resource blocks used for transmitting SRS. Indicates the road loss compensation coefficient. The cumulative power adjustment value can be adjusted by the terminal based on the power adjustment field in the DCI.

Furthermore, since the target carriers for at least two different first information transmissions are different, for multi-carrier random access processes, it allows the terminal to flexibly adjust the transmission carrier, improving communication system performance.
