Description

Power configuration method and device

[0001] This application claims priority to Chinese Patent Application No. 202410940323.2, filed on July 12, 2024, entitled "Power Configuration Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a power configuration method and apparatus. Background Technology

[0003] In satellite communication scenarios, assuming a satellite's total power is constant, it uses inter-beam power sharing to manage the power allocation of active beams. For example, within a scheduling window, the satellite can allocate less power to one active beam and more power to the others. When reallocating power to active beams, the power of the active beams needs to be indicated to the terminal devices so they can adjust their downlink data reception power accordingly. However, the current power indication method is at the terminal device level. Therefore, when indicating the power of the active beams to all terminal devices in the active beams using the current method, the satellite needs to send dedicated indication information to each terminal device, resulting in significant signaling overhead. Summary of the Invention

[0004] This application provides a power configuration method and apparatus that can effectively reduce signaling overhead when indicating the power of the active beam to a terminal device.

[0005] In a first aspect, embodiments of this application provide a power configuration method applied to a terminal device. The method includes: receiving first information at the cell level or beam level from a network device, the first information indicating a first downlink power offset configuration of a first active beam operating under the network device after a change in the downlink power allocation of the active beam of the network device; and adjusting the received power of downlink data based on the first information.

[0006] In the method described in the first aspect, the first information is cell-level or beam-level information. All terminal devices under a cell served by the first active beam, or all terminal devices under the first active beam, can know the first downlink power offset configuration of the first active beam after the downlink power allocation of the network device changes, based on the received first information. Compared to the power indication method at the terminal device level, this method can effectively reduce signaling overhead when indicating the power of the active beam to the terminal device by reducing the amount of personalized information (such as terminal identification information) carried when sending dedicated indication information to the terminal device.

[0007] In one possible implementation, the network device is a satellite, which has the function of allocating downlink power for the active beam. This allows for effective reduction of signaling overhead when the satellite instructs the terminal device on the power of the active beam, based on the method described in the first aspect.

[0008] In one possible implementation, the first information is carried as a broadcast message. This allows the terminal device to receive the first information transmitted via broadcast. Broadcasting can further reduce the signaling overhead when indicatively specifying the power of the active beam by reducing the amount of first information that needs to be transmitted.

[0009] In one possible implementation, the first information is downlink control information or group downlink control information.

[0010] In this way, the terminal device can receive downlink control information or group downlink control information to know the first downlink power offset configuration of the first active beam. Specifically, when the first information is group downlink control information, the terminal device can receive the first information transmitted via multicast. Multicast can further reduce the signaling overhead when indicating the power of the active beam by reducing the number of first messages that need to be transmitted.

[0011] In one possible implementation, before receiving the first information at the cell level or beam level from the network device, the method further includes: receiving second information from the network device, the second information being carried in a broadcast message; the second information includes M downlink power offset configurations, the M downlink power offset configurations including a first downlink power offset configuration, where M is a positive integer greater than or equal to 1.

[0012] In this way, the terminal device can first receive the second information transmitted via broadcast and pre-store the M downlink power offset configurations included in the second information; then, it receives the first information, which indicates that the downlink power offset configuration of the first active beam is the first downlink power offset configuration among the M downlink power offset configurations. For example, the first information can be an identifier of the first downlink power offset configuration. Since in the prior art downlink power offset configuration, multiple downlink power offset configurations need to be pre-configured to the terminal device via dedicated RRC messages, the second information transmitted via broadcast can reduce the signaling overhead when indicating the power of the active beam by reducing the number of second information messages that need to be transmitted.

[0013] In one possible implementation, before receiving the first information at the cell level or beam level from the network device, the method further includes: receiving third information from the network device, the third information being used to configure N discontinuous reception DTX patterns, wherein the first DTX pattern among the N DTX patterns is associated with a first downlink power offset configuration, and N is a positive integer greater than or equal to 1 and less than or equal to M; wherein the first information indicates the first downlink power offset configuration of the first active beam operating under the network device after the downlink power allocation of the active beam of the network device changes by indicating the first DTX pattern.

[0014] In this way, the terminal device can be pre-configured with N DTX patterns, and the first DTX pattern among the N DTX patterns is associated with the first downlink power offset configuration. Thus, the first information can implicitly indicate the first downlink power offset configuration by indicating the first DTX pattern.

[0015] In one possible implementation, before receiving the first information at the cell level or beam level from the network device, the method further includes: receiving fourth information from the network device, the fourth information including configuration parameters of a DTX pattern; wherein the configuration parameters of a DTX pattern include: period, N start times and activation duration, the first start time among the N start times is associated with a first downlink power offset configuration, and N is a positive integer greater than or equal to 1 and less than or equal to M; wherein the first information indicates the first downlink power offset configuration of the first active beam operating under the network device after the downlink power allocation of the active beam of the network device changes by indicating the first start time.

[0016] In this way, the terminal device can be pre-configured with a DTX pattern, which has N start times configured. Among the N start times, the first start time is associated with the first downlink power offset configuration. Thus, the first information can implicitly indicate the first downlink power offset configuration by indicating the first start time.

[0017] In one possible implementation, before receiving the first information at the cell level or beam level from the network device, the method further includes: receiving fourth information from the network device, the fourth information including configuration parameters of a DTX pattern; wherein the configuration parameters of a DTX pattern include: period, start time, and N activation durations, the first activation duration among the N activation durations being associated with a first downlink power offset configuration, and N being a positive integer greater than or equal to 1 and less than or equal to M; wherein the first information, by indicating the first activation duration, indicates the first downlink power offset configuration of the first active beam operating under the network device after the downlink power allocation of the active beam of the network device changes.

[0018] In this way, the terminal device can be pre-configured with a DTX pattern, in which N activation durations are configured. Among the N activation durations, the first activation duration is associated with the first downlink power offset configuration. Thus, the first information can implicitly indicate the first downlink power offset configuration by indicating the first activation duration.

[0019] In one possible implementation, before receiving the first information at the cell level or beam level from the network device, the method further includes: receiving fourth information from the network device, the fourth information including configuration parameters of a DTX pattern; wherein the configuration parameters of a DTX pattern include: N periods, a start time, and an activation duration, the first period of the N periods being associated with a first downlink power offset configuration, and N being a positive integer greater than or equal to 1 and less than or equal to M; wherein the first information indicates, by indicating the one period, the first downlink power offset configuration of the first active beam operating under the network device after a change in the downlink power allocation of the active beam of the network device.

[0020] In this way, the terminal device can be pre-configured with a DTX pattern, which has N cycles configured. The first cycle of the N cycles is associated with the first downlink power offset configuration, so the first information can implicitly indicate the first downlink power offset configuration by indicating the first cycle.

[0021] In one possible implementation, after receiving the first information at the cell level or beam level from the network device and before adjusting the received power of the downlink data based on the first information, the method further includes: receiving fifth information at the terminal device level from the network device, the fifth information being used to indicate the second downlink power offset configuration of the terminal device; the aforementioned adjustment of the received power of the downlink data based on the first information includes: adjusting the received power of the downlink data based on the first downlink power offset configuration of the first active beam and the second downlink power offset configuration of the terminal device.

[0022] In this way, when different terminal devices under the first active beam service in a cell or different terminals under the first active beam need to adjust downlink power according to traffic volume, the terminal devices can also receive the fifth information and achieve more personalized power adjustment through the first information and the fifth information.

[0023] In one possible implementation, the granularity of the first downlink power offset configuration of the first active beam is greater than the granularity of the second downlink power offset configuration of the terminal device.

[0024] This effectively saves signaling overhead compared to using downlink power offset configuration at the terminal device level for indication.

[0025] Secondly, embodiments of this application provide a power configuration method applied to a terminal device. The method includes: receiving sixth information from a network device, the sixth information indicating a first number of active beams in the network device after a change in the number of active beams in the network device, the sixth information being carried in a broadcast message; and adjusting the downlink data receiving power based on the first number and the second number, the second number being the number of active beams in the network device before the change in the number of active beams in the network device.

[0026] In the method described in the second aspect, the sixth information can indicate the first number of active beams after a change in the number of active beams in the network device. Thus, the terminal device can determine the downlink power offset of the active beams based on the first number and the second number of active beams before the change, and adjust the received power of the downlink data based on this downlink power offset. This approach eliminates the need for the network device to send specific offset values ​​and other information to the terminal device, effectively reducing signaling overhead.

[0027] In one possible implementation, the network device is a satellite, which has the function of allocating downlink power to active beams based on the number of active beams in operation. This allows for effective reduction of signaling overhead when the satellite instructs the terminal device on the power of the active beams, based on the method described in the second aspect.

[0028] In one possible implementation, the sixth information includes the state of each wave position under the network device after the number of active beams of the network device changes, wherein the state of the wave position is either scanning or non-scanning; the method further includes: determining the first number of active beams under the network device based on the number of wave positions in the scanning state in the sixth information.

[0029] In this way, the terminal device can obtain the first working quantity by counting the number of wave positions in the scanning state in the sixth information.

[0030] In one possible implementation, adjusting the received power of downlink data based on the first number of working devices and the second number of working devices includes: determining a first downlink power offset configuration of a first active beam operating under the network device based on the ratio of the first number of working devices and the second number of working devices; and adjusting the received power of downlink data based on the first downlink power offset configuration of the first active beam.

[0031] In one possible implementation, before adjusting the received power of downlink data based on the first downlink power offset configuration of the first activated beam, the method further includes: receiving fifth information at the terminal device level from the network device, the fifth information being used to indicate the second downlink power offset configuration of the terminal device; the adjustment of the received power of downlink data based on the first downlink power offset configuration of the first activated beam includes: adjusting the received power of downlink data based on the first downlink power offset configuration of the first activated beam and the second downlink power offset configuration of the terminal device.

[0032] In this way, when different terminal devices under the first active beam service in a cell or different terminals under the first active beam need to adjust downlink power according to traffic volume, the terminal devices can also receive the fifth information and achieve more personalized power adjustment through the sixth information and the fifth information.

[0033] In one possible implementation, the granularity of the first downlink power offset configuration of the first active beam is greater than the granularity of the second downlink power offset configuration of the terminal device.

[0068] The embodiments of this application will now be described with reference to the accompanying drawings.

[0069] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0070] It should be understood that in this application, "at least one (item)" means one or more, and "more than" means two or more. "And / or" is used to describe the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can represent three cases: only A exists, only B exists, and both A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0071] The embodiments of this application can be applied to communication systems such as non-terrestrial networks (NTNs). NTNs are characterized by long communication distances, large coverage areas, and flexible networking, providing services not only to fixed terminals but also to various types of mobile terminals. NTNs can utilize equipment such as drones, high-altitude platforms, and / or satellites for networking. Taking satellites as an example, for locations where base stations cannot be deployed, such as oceans, deserts, and the air, base stations or some base station functions can be deployed on satellites, thereby providing seamless coverage for terminal devices. Furthermore, because satellites are less affected by natural disasters, satellite communication can effectively improve the reliability of communication systems.

[0072] The following uses a satellite communication system as an example to introduce the communication system of this application embodiment:

[0073] Referring to Figure 1, this communication system is a convergence system integrating satellite communication and 5G (5th generation mobile networks) technologies, comprising at least one terminal device, at least one network device, a ground station, and a core network. The terminal device and network device exchange user service data and signaling via New Radio (NR) technology. Network devices exchange signaling and transmit user service data via the XN interface. Network devices and the ground station exchange core network signaling and transmit user service data via the NG interface. The ground station connects to the core network, which includes user plane and control plane functional entities. For example, user plane functional entities include the User Plane Function (UPF) and data network, etc. The UPF is responsible for managing user service data transmission and traffic statistics. Control plane functional entities include the Access and Mobility Management Function (AMF), Session Management Function (SMF), security authentication, and accounting, etc. The AMF is responsible for user access management, and the SMF is responsible for session establishment, modification, and release.

These satellites can be geostationary earth orbit (GEO) satellites, medium earth orbit (MEO) satellites, or low earth orbit (LEO) satellites, etc. Optionally, the satellite's operating mode can be transparent mode or regenerative mode.

[0076] It is understood that the above-described communication system is merely an example, and this application can also be applied to other NTN communication systems besides those described above, such as NTN communication systems integrated with the Internet of Things (IoT) field. Furthermore, the aforementioned network equipment may also include high altitude platform station (HAPS) equipment and / or drones, etc.

[0077] The following uses a satellite communication system as an example to illustrate the relevant technologies and concepts involved in the embodiments of this application:

[0078] I. Beam-hopping technology

[0079] In satellite communication systems, a single satellite has a large coverage area, but the coverage area of ​​a single active beam is relatively small. To enable a satellite to achieve full coverage of a corresponding area, a single satellite can use beam hopping technology to manage the active beam. Specifically, because the number of positions within a satellite's coverage area is large, and usually much larger than the number of active beams simultaneously transmitted by the satellite, the satellite cannot simultaneously provide service to all positions within the coverage area. Currently, the active beam can provide service to all positions within the satellite's coverage area through time-division multiplexing. For example, as shown in Figure 2, for active beam 1, active beam 1 scans the first position during the first dwell time, the second position during the second dwell time, the third position during the third dwell time, and so on. During the scanning of each position, active beam 1 is responsible for controlling data transmission (such as synchronization signal (SSB) scanning and system information block (SIB) broadcasting) and service data transmission. In this way, the same active beam can provide service to multiple positions by continuously adjusting the scanned positions.

[0080] II. Jumping Beam Pattern

[0081] Satellites can configure beam hopping patterns to terminal devices to indicate the dwell status of active beams. The configuration methods for beam hopping patterns include, but are not limited to, the following two:

[0082] Method 1: The hopping beam pattern includes the stationed / unstationed status (or scanned / non-scanned status) of all saturations within the satellite coverage area within one or more consecutive scheduling windows. For example, the stationed status is "on," and the unstationed status is "off." In this way, the satellite can indicate the hopping beam pattern to terminal devices for all saturations, allowing each terminal device to know whether all saturations are active beamstations based on the hopping beam pattern.

[0083] Method 2: The hopping beam pattern includes the camped / uncamped status of a certain beam position within one or more consecutive scheduling windows. In this way, the satellite can indicate the hopping beam pattern to the terminal equipment under a certain beam position, so that the terminal equipment under that beam position can know whether the beam position is activated and camped based on the hopping beam pattern.

[0084] III. Inter-beam power sharing

[0085] Inter-beam power sharing refers to the dynamic allocation of power among active beams by a satellite in a scenario where the total power of the satellite is constant. Adjustments in the traffic load of terminal equipment under active beams and / or changes in the number of active beams can lead to a reallocation of power among the active beams. For example, if the traffic load in the positions where one active beam should reside decreases while the traffic load in the positions of the remaining active beams remains unchanged or increases, the terminal equipment can reduce the power of that active beam and increase the power of the remaining active beams. Similarly, if one active beam is deactivated while the remaining active beams remain active, the change in the number of active beams can allow the power of that active beam to be set to 0, and power to the remaining active beams to be reallocated.

[0086] For example, as shown in Figure 3, suppose a satellite is configured with K active beams, namely active beam1, active beam2, active beam3, ..., active beamK. The total power of the satellite is constant, and the satellite uses a uniform power distribution method to allocate power to the active beams. Then, in scheduling window 1, the power of active beam1 to active beamK is the same, which is 1 / K of the total satellite power. If at the beginning of scheduling window 2, the traffic under active beam3 is cleared to 0 or active beam3 is configured to be inactive, then the satellite can allocate 0 power to active beam3. The power originally allocated to active beam3 can be allocated to active beams other than active beam3, thereby increasing the power of active beams other than active beam3.

[0087] It should be noted that the scenario in which the active beam switches from working to inactive can be triggered by one or more of the following: changes in channel state, changes in system load, or changes in the traffic volume of the terminal device. Specifically, when the traffic volume of the terminal device under an active beam decreases to 0, that active beam switches from working to inactive.

[0088] IV. Downlink Power Offset Configuration

[0089] Currently, to meet the service needs of different terminal devices, satellites can send different downlink power offset configurations to different terminal devices. The downlink power offset configuration depends on the configuration of reference signal resources and the activation of those resources.

[0090] Taking a 5G communication system as an example, firstly, the base station in 5G configures multiple non-zero power channel state information reference signals (NZP-CSI-RS) resources for the connected terminal by sending a dedicated RRC message. Each NZP-CSI-RS resource includes the following in the protocol specification:

[0091] Wherein, nzp-CSI-RS-ResourceId represents the identifier of the NZP-CSI-RS resource; resourceMapping represents the resource element mapping of the NZP-CSI-RS resource in the time-frequency domain; powerControlOffset represents the power ratio of the energy per resource element (EPRE) of the physical downlink shared channel (PDSCH) to the EPRE of the NZP-CSI-RS; and powerControlOffsetSS represents the power ratio of the EPRE of the NZP-CSI-RS to the EPRE of the synchronization signal block (SSB).

[0092] Then, in 5G, the base station triggers NZP-CSI-RS resources to the connected terminal via media access control (MAC) signaling to activate different downlink power offset configurations. Specifically, the MAC signaling may carry the identifier of the target NZP-CSI-RS resource, which is any one of a plurality of pre-configured NZP-CSI-RS resources.

[0093] Finally, after the terminal device receives the MAC signaling to activate the target NZP-CSI-RS resource, it can first determine the EPR of the target NZP-CSI-RS based on the EPR of the SSB and the value indicated by the powerControlOffset; then, based on the EPR of the target NZP-CSI-RS and the value indicated by the powerControlOffset, it can determine the EPR of the PDSCH, thereby determining the power of the received PDSCH based on the EPR of the PDSCH. Furthermore, the terminal device can also identify the number of demodulation reference signal code division multiplexing (DMRS CDM) groups configured in the network device, and find the power ratio between the EPR of the PDSCH and the ERPE of the DMRS based on the number of DMRS CDM groups, thereby determining the power of the received DMRS based on the found power ratio and the EPR of the PDSCH.

[0094] The technical problems of the embodiments of this application will be explained below in conjunction with the above-described technology: Currently, in the case of inter-beam power sharing in satellite communication systems, the satellite can dynamically allocate the power of the active beam. After reallocating the power of the active beam, the satellite needs to indicate the reallocated power of the active beam to the terminal device. If the satellite adopts the downlink power offset configuration method described above to indicate the reallocated power of the active beam to the terminal device, it depends on the configuration of reference signal resources and the activation of reference signal resources. Since the downlink power offset configuration method described above is to meet the service needs of different terminal devices, the downlink power offset configuration method described above is a power configuration method at the terminal device level (or it can also be called a terminal device granularity). If the power reallocated by an active beam is indicated to all terminal devices under that active beam in this manner, the reference signal resources of each terminal device in the active beam need to be reconfigured and activated. This requires the satellite to send dedicated RRC messages and MAC signaling to each terminal device under that active beam to configure the same downlink power offset configuration of the active beam for each terminal device. This method results in high signaling overhead due to the need to carry personalized information of the terminal devices (such as terminal identification information) and the large number of messages and signaling sent. In order to reduce the signaling overhead when indicating the power of the active beam to terminal devices, this application proposes a power configuration method, which can be applied to the communication system shown in Figure 1, and will not be described in detail here.

[0095] The following examples illustrate the power configuration method proposed in this application under two scenarios of inter-beam power sharing:

[0096] Scenario 1: When the downlink power allocation of the active beam of a network device changes, how should the network device indicate the downlink power of the active beam to the terminal device?

[0097] Figure 4 shows a flowchart of a power configuration method provided in an embodiment of this application under the first scenario. As shown in Figure 4, the method includes steps 401 to 402. The execution subject of the method shown in Figure 4 can be a terminal device and a network device, or the subject can be a chip in the terminal device and a chip in the network device. Alternatively, the execution subject of the method shown in Figure 4 can also be other types of products, and those skilled in the art can further expand upon this based on the content disclosed in the specification. The execution subject of the method shown in Figure 4 and the following embodiments are examples of terminal devices and network devices. Wherein:

[0098] 401. The network device sends cell-level or beam-level first information to the terminal device. The first information indicates the first downlink power offset configuration of the first active beam operating under the network device after the downlink power allocation of the active beam of the network device changes. Accordingly, the terminal device receives the first information.

[0099] In this embodiment of the application, the network device has the function of allocating downlink power for the active beam. For example, the network device can be a satellite in a satellite communication system.

[0100] Changes in downlink power allocation of the active beam of a network device can be triggered by one or more of the following factors: for example, adjustments in the traffic volume of terminal devices under the active beam, changes in the number of active beams, etc.

[0101] The traffic adjustment of the active beam includes, but is not limited to: increasing, decreasing and / or clearing the traffic of the terminal equipment in one or more active beam positions.

[0102] The changes in the number of active beams include, but are not limited to, increases or decreases in the number of active beams. These changes can be triggered by one or more of the following: changes in channel state, system load, or adjustments in the traffic volume of terminal devices. For example, if the channel state corresponding to the third active beam (active beam3) deteriorates, the network device can configure active beam3 to be inactive. Similarly, if the system load increases, the network device can configure active beam3 to be inactive to reduce unnecessary downlink data transmission under active beam3. Furthermore, if the traffic volume of terminal devices in the positions where active beam3 should reside is reduced to zero, the network device can configure active beam3 to be inactive.

[0103] After the downlink power allocation of the active beam of a network device changes, the network device can indicate the downlink power of the active beam to a terminal device, which is a terminal device under the active beam. Taking the active beam as the first active beam as an example, the network device can send first information to the terminal device served by the first active beam, and indicate the downlink power of the first active beam through the first downlink power offset configuration indicated by the first information.

[0104] The first downlink power offset configuration includes a set of power offset parameters, namely powerControlOffset_r19 and powerControlOffsetSS_r19. powerControlOffset_r19 represents the power ratio of PDSCH EPRE to CSI-RS, and powerControlOffsetSS_r19 represents the power ratio of CSI-RS to SSB EPRE. These two power ratios can be used to determine the power of the first active beam transmitting downlink data such as PDSCH / CSI-RS. For example, the value ranges of powerControlOffset_r19 and powerControlOffsetSS_r19 are shown in Formula 1 below: [0dB, min(P max EIRP max -Gt max )] (Formula 1)

[0105] Among them, P max It is the maximum transmit power of the network device, EIRP max It is the maximum value of the effective isotropic radiated power (EIRP) of a single activated beam, Gt maxIt is the maximum value of the antenna gain of a single active beam. Formula 1 indicates that the minimum downlink power offset of the first active beam is 0 dB, and the maximum value is P. max With EIRP max -Gt max The minimum value in.

[0106] Optionally, the first information can be at the cell level. When the first information is at the cell level, sending the first information to the terminal devices serving the first active beam means that the network device can send the first information to all terminal devices in a cell serving the first active beam. Compared to the downlink power offset configuration at the terminal device level in the prior art (i.e., sending dedicated RRC messages and MAC signaling to each terminal device), the cell-level first information applies to a cell and does not need to carry personalized information for each terminal device (such as terminal identification information carried in dedicated RRC messages), which can save some signaling overhead.

[0107] Optionally, the first information can be beam-level. When the first information is beam-level (or wavelet-level), sending the first information to the terminal devices served by the first active beam means that the network device can send the first information to all terminal devices under the first active beam. Compared with the downlink power offset configuration at the terminal device level in the prior art, the beam-level first information is applicable to one beam (or one wavelet), and does not need to carry the personalized information of each terminal device, which can save some signaling overhead.

[0108] The following describes how the first piece of information is carried:

[0109] In a first possible implementation, the first information can be carried in a broadcast message, which can be a system information block (SIB) message, etc. This application does not limit this. The first information includes the offset value of the downlink power offset configuration of the first active beam. For example, the first information includes the values ​​of the power offset parameters powerControlOffset_r19 and powerControlOffsetSS_r19.

[0110] In this way, network devices can send the first information via broadcast. The first information can be received by all terminal devices in a cell serving the first active beam / all terminal devices in the first active beam. Compared with the downlink power offset configuration at the terminal device level in the prior art, this method can effectively reduce signaling overhead by reducing the number of first information sent.

[0111] In the second possible implementation, the first information is Group downlink control information (Group DCI), which is transmitted via multicast. The first information includes the activation parameters of the first downlink power offset configuration of the first active beam.

[0112] In this way, network devices can send the first information via multicast. The first information can be received by all terminal devices in a cell served by the first active beam / all terminal devices in the first active beam. With the downlink power offset configuration at the terminal device level in the technology, this method can effectively reduce signaling overhead by reducing the number of first information sent.

[0113] Specifically, in this approach, before sending the first information, the network device may first send a second information. The second information is carried in a broadcast message and includes M downlink power offset configurations, which include a first downlink power offset configuration. Here, M is a positive integer greater than or equal to 1, and each of the M downlink power offset configurations includes multiple sets of power offset parameters, including one set of power offset parameters from the first downlink power offset configuration.

[0114] Optionally, the second information can also be at the cell / beam level. In this case, the network device can broadcast M downlink power offset configurations to all terminal devices in a cell served by the first active beam, or to all terminal devices under the first active beam. Compared to the prior art where terminal device-level downlink power offset configuration requires sending a dedicated RRC message to each terminal device in the active beam to configure reference signal resources, this reduces signaling overhead by decreasing the number of messages sent.

[0115] After receiving M downlink power offset configurations indicated by a broadcast method, the terminal device can store the M downlink power offset configurations. Then, the network device can activate a set of power offset parameters of the first downlink power offset configuration by sending a first message carrying the identifier of the first downlink power offset configuration.

[0116] In the third possible implementation, the first information is downlink control information (DCI), which is sent via unicast. The first information includes activation parameters for the first downlink power offset configuration of the first active beam. Furthermore, before the network device sends the first information to the terminal device, the network device first broadcasts the second information to the terminal device to indicate M downlink power offset configurations. Compared to the prior art where terminal device-level downlink power offset configurations send dedicated RRC messages and MAC signaling to each terminal device in the active beam, this method, although not reducing signaling overhead when sending the first information (both DCI and MAC signaling are sent via unicast), reduces the number of messages sent by broadcasting the second information, thereby reducing signaling overhead. Therefore, overall, it also reduces the signaling overhead when indicating the power of the active beam.

[0117] Optionally, in the second or third possible implementation described above, the activation parameter of the first downlink power offset configuration can be the identifier (ID) corresponding to the set of parameters powerControlOffset_r19 and powerControlOffsetSS_r19. For example, if M is 3, and the network device indicates three downlink power offset configurations to the terminal device through the second information, with the identifiers of these three downlink power offset configurations being 00, 01, and 10 respectively, then the network device can indicate that the first downlink power offset configuration of the first active beam is the downlink power offset configuration corresponding to "00" by sending a DCI or Group DCI carrying "00".

[0118] Optionally, if the downlink power allocation of the active beam of the network device changes, triggering a change in the hopping beam pattern, then a hopping beam pattern can be associated with each of the M downlink power offset configurations. The activation parameter of the first downlink power offset configuration in the second or third possible implementation described above can be the activation parameter of the hopping beam pattern.

[0119] For example, hopping beam patterns can be configured using a discontinuous transmission (DTX) mechanism, where the hopping beam pattern is referred to as a DTX pattern. The configuration parameters of a DTX pattern include: cycle, on-duration, and startoffset. During the on-duration, the network device can transmit an active beam to the terminal device. It is understood that hopping beam patterns can also be configured in other ways, and this application does not limit this to any particular method.

[0120] The following section uses the DTX mechanism as an example to specifically explain the activation parameters of the first downlink power offset configuration in the second or third possible implementation methods mentioned above, which can be the activation parameters of the hopping beam pattern:

[0121] (1) Before the network device sends the first information at the cell level or beam level, the network device may send the third information to the terminal device. The third information is used to configure N DTX patterns. The first DTX pattern among the N DTX patterns is associated with the first downlink power offset configuration, and N is a positive integer greater than or equal to 1 and less than or equal to M.

[0122] The first information indicates the first downlink power offset configuration of the first active beam operating under the network device after the downlink power allocation of the active beam of the network device changes by indicating the first DTX pattern.

[0123] The configuration information of a DTX pattern includes the period, start period, and activation duration. Any two DTX patterns among the N DTX patterns have at least one or more differences in the period, start period, and activation duration.

[0124] Optionally, the third information can be at the cell level or the beam level. When the third information is at the cell level, the network device can configure N DTX patterns for all terminal devices in a cell through the third information. When the third information is at the beam level, the network device can configure N DTX patterns for all terminal devices in the first active beam through the third information.

[0125] Optionally, the network device may first send a second message to configure M downlink power offset configurations, and then send a third message to configure N DTX patterns. When sending the third message, the device may configure an associated downlink power offset configuration for each DTX pattern. For example, the associated downlink power offset configuration for the first DTX pattern may be configured as the first downlink power offset configuration.

[0126] Optionally, the network device may first send a third message to configure N DTX patterns, and then send a second message to configure M downlink power offset configurations, and configure the associated downlink power offset configuration for each DTX pattern when sending the second message.

[0127] Optionally, the network device can send the second and third information simultaneously, and configure an associated downlink power offset for each DTX pattern.

[0128] For example, taking the third information as the cell level, N DTX patterns can be configured according to the following specifications:

[0129] Wherein, CellDTX-Config-NTN represents the DTX configuration mechanism in this application, and CellDTX-Config-r18 represents the DTX and DRX configuration mechanism in the current 3GPP protocol r18 version. The above provision means that at least one, and at most maxNrofCellDTX-Config-NTN, DTX patterns are configured according to the DTX configuration mechanism in the current r18 version. Specifically, in the DTX configuration mechanism of the aforementioned r18 version, cellDTXDRX-onDurationTimer-r18 is used to configure the activation duration of DTX and / or DRX patterns, cellDTXDRX-CycleStartoffset-r18 is used to configure the period and start time of DTX and / or DRX patterns, cellDTXDRX-SlotOffset-r18 is used to configure the slot offset value of DTX and / or DRX patterns, cellDTXDRXconfigType-r18 is used to configure the type of DTX and / or DRX patterns, which can be dtx or dtxdrx in this application, indicating that it is applied to the DTX pattern configuration in this application, and cellDTXDRXactivationStatus-r18 indicates whether DTX and / or DRX patterns are activated. This application will not elaborate on the various parameters of the DTX configuration mechanism in the r18 version.

[0130] For example, still taking the third information as the cell level, the downlink power offset configuration can be associated with N DTX patterns in the following way:

[0131] As shown in Figure 5, PowerControlOffset-NTN indicates that the network device has configured four downlink power offset configurations for the terminal device (equivalent to M being 4), namely X1, X2, X3, and X4; cellDTX-Config-NTN indicates that the network device has configured three DTX patterns for the terminal device, namely cellDTX-1, cellDTX-2, and cellDTX-3. Therefore, cellDTX-1 can be associated with X1, cellDTX-2 with X2, and cellDTX-3 with X3.

[0132] Furthermore, the network device can implicitly indicate the first downlink power offset configuration of the first active beam by sending first information, which carries the activation parameters of the first DTX pattern among N DTX patterns. For example, the activation parameters of the first DTX pattern may include detailed information about the first DTX pattern during configuration, such as the information specified in version r18 above; or, when configuring N DTX patterns, if a corresponding identifier is configured for each DTX pattern, the activation parameters of the first DTX pattern may include the identifier corresponding to the first DTX pattern. This application does not limit the form of the activation parameters of the first DTX pattern.

[0133] (2) Before the network device sends the first information at the cell level or beam level, the network device sends the fourth information to the terminal device; the fourth information includes the configuration parameters of a DTX pattern. The configuration parameters of a DTX pattern include: period, N start times and activation duration; the first start time among the N start times is associated with the first downlink power offset configuration, and N is a positive integer greater than or equal to 1 and less than or equal to M.

[0134] The first information indicates the first downlink power offset configuration of the first active beam operating under the network device after the downlink power allocation of the active beam of the network device changes by indicating the first start time.

[0135] Among them, N start times are different.

[0136] Optionally, the fourth information can be at the cell level or the beam level. When the fourth information is at the cell level, the network device can use the fourth information to configure a DTX pattern including N start times for all terminal devices in a cell. When the third information is at the beam level, the network device can use the fourth information to configure a DTX pattern including N start times for all terminal devices in the first active beam.

[0137] Optionally, the network device may first send a second message to configure M downlink power offset configurations, and then send a fourth message to configure a DTX pattern including N start times. When sending the third message, the associated downlink power offset configuration is configured for each start time. For example, the associated downlink power offset configuration is configured as the first downlink power offset configuration for the first start time.

[0138] Optionally, the network device may first send a fourth message to configure a DTX pattern including N start times, and then send a second message to configure M downlink power offset configurations, configuring the associated downlink power offset configuration for each start time when sending the second message.

[0139] Optionally, the network device can send the second and fourth information simultaneously, and configure an associated downlink power offset for each start time.

[0140] For example, taking the fourth information as the cell level, a DTX pattern including N start times can be configured according to the following specifications:

[0141] In this application, CellDTX-Config-NTN represents the DTX configuration mechanism. Compared to CellDTX-Config-r18 defined in the current r18 version, CellDTX-Config-NTN modifies cellDTXDRX-CycleStartoffset-r18, while the rest remains unchanged. For example, SEQUENCE(SIZE(1..maxNrofDurationoffsets)OF)INTEGER(0..9)) indicates that at least one, and at most maxNrofDurationoffsets, start times need to be configured, and the value of each start time can be any value in (0..9).

[0142] For example, still taking the fourth information as the cell level, the downlink power offset configuration can be associated with N start times in a DTX pattern in the following way:

[0143] As shown in Figure 6, PowerControlOffset-NTN indicates that the network device has configured four downlink power offset configurations for the terminal device (equivalent to M being 4), namely X1, X2, X3, and X4; cellDTX-Config-NTN indicates that the network device has configured one DTX pattern for the terminal device, which includes three start times: StartOffset-1, StartOffset-2, and StartOffset-3. Therefore, StartOffset-1 can be associated with X1, StartOffset-2 with X2, and StartOffset-3 with X3.

[0144] Furthermore, the network device can implicitly indicate the first downlink power offset configuration of the first active beam by sending a first message, which carries the activation parameters of the first start time among N start times.

[0145] (3) In the above (2) method, the fourth information sent by the network device to the terminal may include the following configuration parameters of a DTX pattern: period, start time and N activation durations; the first activation duration among the N activation durations is associated with the first downlink power offset configuration, the N activation durations are different, and N is a positive integer greater than or equal to 1 and less than or equal to M.

[0146] The first information indicates the first downlink power offset configuration of the first active beam operating under the network device after the downlink power allocation of the active beam of the network device changes by indicating the first activation duration.

[0147] Optionally, the fourth information can be at the cell level or the beam level. When the fourth information is at the cell level, the network device can use the fourth information to configure a DTX pattern including N activation durations to all terminal devices in a cell. When the third information is at the beam level, the network device can use the fourth information to configure a DTX pattern including N activation durations to all terminal devices in the first active beam.

[0148] Optionally, the network device may send the second information first and then the fourth information, or send the fourth information first and then the second information, or send the second information and the fourth information at the same time. This application does not limit this, and you can refer to the relevant description in (2) above.

[0149] For example, taking the fourth information as the cell level, the cellDTXDRX-onDurationTimer-r18 in the CellDTX-Config-r18 defined in the DTX configuration mechanism of the current r18 version can be modified, while the rest remains unchanged, thus obtaining a way to configure multiple activation durations for a DTX pattern. This application will not elaborate on this further. Furthermore, the downlink power offset configuration associated with N activation durations in a DTX pattern can be referenced in Figure 7, where OnDuration-1, OnDuration-2, and OnDuration-3 are the three activation durations configured by the network device for the terminal device. Therefore, OnDuration-1 can be associated with X1, OnDuration-2 with X2, and OnDuration-3 with X3.

[0150] Furthermore, the network device can implicitly indicate the first downlink power offset configuration of the first active beam by sending a first message, which carries the activation parameter of the first active duration among N active durations.

[0151] (4) In the above (2) method, the fourth information sent by the network device to the terminal may include the following configuration parameters of a DTX pattern: N cycles, start time and activation duration; the first cycle of the N cycles is associated with the first downlink power offset configuration, the N cycles are different, and N is a positive integer greater than or equal to 1 and less than or equal to M.

[0152] The first information indicates the first downlink power offset configuration of the first active beam operating under the network device after the downlink power allocation of the active beam of the network device changes by indicating the first cycle.

[0153] Optionally, the fourth information can be at the cell level or the beam level. When the fourth information is at the cell level, the network device can use the fourth information to configure a DTX pattern including N periods to all terminal devices in a cell. When the third information is at the beam level, the network device can use the fourth information to configure a DTX pattern including N periods to all terminal devices in the first active beam.

[0154] Optionally, the network device may send the second information first and then the fourth information, or send the fourth information first and then the second information, or send the second information and the fourth information at the same time. This application does not limit this, and you can refer to the relevant description in (2) above.

[0155] For example, taking the fourth information as the cell level, the cellDTXDRX-CycleStartoffset-r18 in the CellDTX-Config-r18 defined in the DTX configuration mechanism of the current r18 version can be modified, while the rest remains unchanged, thus obtaining a way to configure multiple cycles for a DTX pattern. This application will not elaborate on this further. Furthermore, the downlink power offset configuration associated with N cycles in a DTX pattern can be referenced in Figure 8, where Cycle-1, Cycle-2, and Cycle-3 are the three cycles configured by the network device for the terminal device. Cycle-1 can be associated with X1, Cycle-2 with X2, and Cycle-3 with X3.

[0156] Furthermore, the network device can implicitly indicate the first downlink power offset configuration of the first active beam by sending a first message carrying the activation parameters of the first cycle out of N cycles.

[0157] It is understood that when the hopping beam pattern is configured in other ways, the above-described method can also be used to associate different downlink power offset configurations with different hopping beam patterns, thereby implicitly indicating the first downlink power offset configuration of the first active beam by activating the hopping beam pattern. This application does not limit this.

[0158] 402. The terminal device adjusts the downlink data receiving power based on the first information.

[0159] Specifically, after receiving the first information, the terminal device can determine the downlink power of the first active beam according to the first downlink power offset configuration indicated by the first information. The downlink power of the first active beam includes, but is not limited to, the power of the network device transmitting downlink data such as PDSCH / CSI-RS through the first active beam. Furthermore, the terminal device can adjust the receiving power of downlink data such as PDSCH / CSI-RS according to the downlink power of the first active beam.

[0160] Based on the embodiment described in Figure 4, the network device can send cell-level or beam-level first information to the terminal devices so that all terminal devices under a cell served by the first active beam, or all terminal devices under the first active beam, are aware of the first downlink power offset configuration of the first active beam. Compared to the power indication method at the terminal device level, this method can effectively reduce signaling overhead when indicating the power of the active beam to the terminal devices by reducing the amount of personalized information (such as terminal identification information) carried when sending dedicated indication information to the terminal devices.

[0161] The second scenario: When the number of active beams of a network device changes and the network device's power sharing adopts a uniform distribution principle, how should the network device indicate the downlink power of the active beams to the terminal device?

[0162] It should be noted that when the number of active beams of a network device changes and the network device adopts a uniform distribution principle, the downlink power of the active beams will be redistributed. Therefore, either the second scenario or the first scenario described below can be used to indicate the downlink power of the active beams to the terminal device. When the number of active beams of a network device changes and the network device does not adopt a uniform distribution principle, the first scenario described above can be used to indicate the downlink power of the active beams to the terminal device.

[0163] Figure 9 shows a flowchart illustrating a power configuration method provided in an embodiment of this application under the second scenario. As shown in Figure 9, where:

[0164] 901. The network device sends a sixth message to the terminal device. The sixth message is carried in a broadcast message. The sixth message is used to indicate the first number of active beams of the network device after the number of active beams of the network device changes.

[0165] In this embodiment of the application, the network device has the function of allocating downlink power of the active beam according to the number of active beams. For example, the network device can be a satellite in a satellite communication system.

[0166] In one possible implementation, the network device can combine the configuration of the hopping beam pattern to send the sixth information, which includes the status of all beams under the network device after the number of active beams of the network device changes.

[0167] The state of a wave position is either scanning or non-scanning. A scanning state indicates that the active beam of the network device can scan / reside on that wave position, while a non-scanning state indicates that the active beam of the network device does not scan / reside on that wave position.

[0168] 902. The terminal device adjusts the downlink data receiving power based on the first working quantity and the second working quantity. The second working quantity is the number of working quantities of the network device's downlink active beam before the number of working quantities of the network device's active beam changes.

[0169] In one possible implementation, the terminal device can determine the first working quantity based on the state of all beams under the network device after the number of active beams of the network device changes in the sixth information. For example, the number of beams in the scanning state can be counted and determined as the first working quantity.

[0170] Similarly, the terminal device can obtain the number of active beams in the network device before the number of active beams changes, i.e., the second number of active beams. Then, based on the ratio of the first number of active beams to the second number of active beams, it determines the downlink power offset configuration (i.e., the downlink power offset value) of the still-active active beams. Since the network device uses a uniform distribution principle to allocate power to the active beams, the downlink power offset value of each active beam is the same. Taking one active beam as an example, assuming that the active beam is the first active beam, the downlink power offset value of the first active beam can be determined according to the following formula 2:

[0171] Where N1 represents the first number of active beams, N2 represents the second number of active beams, and P_offset_beam represents the downlink power offset value of the first active beam. It should be noted that the downlink power offset value of the first active beam calculated in this step is an offset value relative to the downlink power offset configuration of the first active beam before the change in the number of active beams. That is, based on the downlink power offset configuration of the first active beam before the change in the number of active beams, what additional offset value needs to be configured. Therefore, the step corresponding to Figure 9 can be executed when the downlink power offset configuration of the active beam is not indicated for the first time. The initial indication of the downlink power offset configuration of the active beam can be implemented according to the embodiment corresponding to Figure 4 above.

[0172] Furthermore, the terminal device can determine the downlink power of the first active beam based on the downlink power offset value of the first active beam, and adjust the receiving power of downlink data such as PDSCH / CSI-RS based on the downlink power of the first active beam.

[0173] Based on the embodiment described in Figure 9, the network device can broadcast sixth information to the terminal device. This sixth information indicates the first number of active beams after a change in the number of active beams operated by the network device. Thus, the terminal device can determine the downlink power offset of the active beams based on the first number and the second number of active beams before the change, and adjust the received power of the downlink data accordingly. This method eliminates the need for the network device to send specific offset values ​​or other information to the terminal device, effectively reducing signaling overhead.

[0174] In both scenarios described above, the network device refers to all terminal devices within a cell under the first active beam, or all terminal devices served by the first active beam, indicating the same first downlink power offset value. However, if different terminal devices within a cell, or different terminal devices under the first active beam, have different service scheduling requirements, then in order to meet these different service scheduling requirements and improve system throughput, further power control can be applied to the different terminal devices within the cell / beam. Specifically:

[0175] After sending the first or sixth information, the network device may also send a fifth information at the terminal device level to the terminal device. The fifth information is used to indicate the second downlink power offset configuration of the terminal device. Accordingly, the terminal device receives the fifth information. Then, the terminal device adjusts the downlink data reception power based on the downlink power offset configuration of the first active beam indicated by the first information and the second downlink power offset configuration of the terminal device. Alternatively, the terminal device first determines the downlink power offset configuration of the first active beam based on the sixth information, and adjusts the downlink data reception power according to the calculated downlink power offset configuration of the first active beam and the second downlink power offset configuration of the terminal device.

[0176] Specifically, the second downlink power offset configuration of the terminal device indicated by the fifth information can refer to the downlink power offset configuration at the terminal device level in the prior art: that is, the fifth information can be carried in MAC signaling, and the MAC signaling activates the second downlink power offset configuration by activating pre-configured reference signal resources (the reference signal resources are configured based on RRC messages). Then, the terminal device can adjust the received power of downlink data such as PDSCH / CSI-RS according to the first downlink power offset configuration and the second downlink power offset configuration.

[0177] Taking PDSCH as an example, the terminal device can adjust the receiving power of PDSCH according to the following formula 3:

[0178] in, EPRE represents the received power of the PDSCH received by the i-th UE. ssb Indicates the EPRE of SSB, It is calculated based on the first downlink power offset configuration, and is the cell-level / beam-level offset of the SSB's EPR (the EPR offset of the j-th cell or beam to which the i-th UE belongs). It is the terminal device-level offset of the i-th UE relative to the SSB's EPRE, calculated based on the second downlink power offset configuration.

[0179] Optionally, the granularity of the first downlink power offset configuration of the first active beam is larger than the granularity of the second downlink power offset configuration of the terminal device. For example, in the prior art, the granularity of the downlink power offset configuration at the terminal device level is 1 dB, meaning the granularity of the second downlink power offset configuration is 1 dB. Therefore, the granularity of the first downlink power offset configuration can be larger than 1 dB. This allows for a coarser granularity to indicate the cell-level / beam-level downlink power offset configuration first, followed by a finer granularity to indicate the terminal device-level downlink power offset configuration. Compared to using the terminal device-level downlink power offset configuration for all indications, this effectively saves signaling overhead.

The chip system can be composed of chips, or it can include chips and other discrete components.

[0222] The communication device 1100 includes at least one processor 1101, used to implement the data processing functions of the terminal device or network device in the methods provided in the embodiments of this application. The communication device 1100 may also include a communication interface 1102, used to implement the transmit and receive operations of the terminal device or network device in the methods provided in the embodiments of this application. In the embodiments of this application, the communication interface may be a transceiver, circuit, bus, module, or other type of communication interface, used to communicate with other devices through a transmission medium. For example, the communication interface 1102 is used for the device in the communication device 1100 to communicate with other devices. The processor 1101 uses the communication interface 1102 to transmit and receive data, and is used to implement the methods described in the above method embodiments.
