Description

Resource allocation methods, apparatus, equipment, media and program products Technical Field

[0001] This application relates to the field of communication technology, and in particular to a resource allocation method, apparatus, device, medium, and program product. Background Technology

[0002] To avoid or reduce electromagnetic radiation harm to the human body when using terminal devices, relevant protocols specify the Specific Absorption Rate (SAR) requirement, stipulating that terminal devices must not exceed this requirement. Related technologies typically address SAR exceedances by power back-off, i.e., reducing power.

[0003] However, satellite communication terminal equipment (terminal equipment that communicates with satellites) typically needs to transmit at high power to maintain a connection with the satellite. Reducing the power will make the connection unstable and affect communication quality. Therefore, related technologies involve having the terminal equipment report the maximum uplink percentage it supports at a certain power level to the network equipment. The network equipment then calculates the uplink time percentage of the terminal equipment in real time to determine whether the terminal equipment needs to reduce or maintain power. However, this method is complex and consumes a lot of power for both the terminal equipment and the network equipment.

[0059] The mobile communication system provided in this application embodiment can be applied to at least one of the following communication scenarios, but not limited to: uplink communication scenario, downlink communication scenario, and sidelink (SL) communication scenario.

[0060] The following section describes the relevant technologies involved in the embodiments of this application:

[0061] • Specific Absorption Rate (SAR):

[0062] SAR is an indicator parameter that measures the intensity of electromagnetic radiation emitted by terminal devices to the human body. In order to avoid electromagnetic radiation damage to the human body from terminal devices such as mobile phones, relevant protocols have strict requirements on the SAR value of terminal devices, and terminal devices cannot exceed these requirements.

[0063] The SAR value is the average measurement value of a terminal device over a period of time. It has the characteristics that the higher the transmission power of the terminal device, the higher the SAR value, and the longer the uplink transmission time, the higher the SAR value.

[0064] Solutions to the SAR exceeding the standard problem:

[0065] To meet SAR performance requirements, terminal devices typically employ devices such as distance sensors to detect the distance between the device and a human body. When the device approaches the human body, a power backoff method is used to reduce transmission power and avoid SAR exceeding limits. However, as SAR testing methods have evolved from testing the SAR of a single terminal device orientation to requiring all faces and edges of the device to be close to a human body for SAR testing, this approach cannot address the potential SAR exceeding issues under various orientations. A more universal solution is needed.

[0066] The emergence of high-power terminal devices (26dBm) in LTE has brought increasing attention to the issue of SAR exceeding limits. Compared to ordinary terminal devices (23dBm), these devices have higher transmit power and therefore higher SAR values. To address the SAR exceeding limit problem of high-power terminal devices in LTE, static uplink / downlink subframe ratios are generally used in current LTE networks, as shown in Table 1. In the table, D represents downlink (DL) subframes, U represents uplink (UL) subframes, and S represents special subframes.

[0067] Table 1

[0068] By excluding uplink-downlink configurations 0 and 6, where the uplink subframe ratio exceeds or equals 50%, the uplink transmission time ratio of terminal devices is limited to less than 50%, which to some extent solves the SAR exceeding problem caused by high-power terminal devices.

[0069] High-power terminal devices have also been introduced into NR, but it's difficult to solve the SAR exceeding problem using methods similar to LTE. This is because LTE only has 7 configurations, all of which are static, while NR has over 60 configurations (as shown in Table 2), and each configuration contains flexible symbols that can be configured for uplink or downlink. This makes calculating the uplink proportion in each configuration extremely difficult. In Table 2, D represents downlink symbols, U represents uplink symbols, and X represents flexible symbols.

[0070] Table 2

[0071] To address this issue, a maximum uplink duty cycle (maxULdutycycle) is introduced, which is the maximum uplink duty cycle that a terminal device reports to the network device that it supports in a certain frequency band. When the uplink duty cycle scheduled by the network device exceeds this maximum duty cycle, the terminal device uses power backoff to reduce the SAR value.

[0072] • SAR exceeding limits issue in satellite communication terminal equipment:

[0073] Satellite communication is increasingly being used in terminal devices (such as mobile phones) as a supplementary network to terrestrial mobile communication to achieve network coverage in remote mountainous areas, deserts, and oceans. Therefore, the use of satellite communication in terminal devices is primarily for emergency communication purposes.

[0074] Satellite communication terminal equipment (terminal equipment that communicates with satellites) currently mostly operates in the FDD band, meaning that these devices may continuously transmit signals for extended periods. This makes SAR (Special Radiation Protection) exceedances more severe in head-to-hand scenarios (where the user holds the terminal close to their head) compared to terrestrial TDD systems. Simply relying on power backoff to address this issue would make satellite communication extremely difficult, potentially even impossible to maintain. This is because satellite communication terminal equipment typically requires high transmission power to maintain a connection with the satellite, and power backoff would make the connection highly unstable.

[0075] To avoid or reduce electromagnetic radiation harm to the human body when using terminal devices, relevant protocols specify SAR (Specific Absorption Scale) requirements, stipulating that terminal devices must not exceed these requirements. Related technologies typically address SAR exceedances by power backoff, i.e., reducing power. However, for satellite communication terminal devices (those communicating with satellites), a high transmission power is usually required to maintain a connection. Reducing power would make the connection unstable, affecting communication quality. Therefore, related technologies involve having the terminal device report its maximum uplink percentage supported at a certain power level to the network device. The network device then calculates the uplink time percentage in real time to determine whether the terminal device needs to reduce or maintain power. However, this method is complex and consumes a significant amount of power for both the terminal and network devices.

[0076] To address the aforementioned problems, embodiments of this application provide a resource configuration method. Figure 2 shows a flowchart of a resource configuration method provided in an exemplary embodiment of this application. This method is executed by a terminal device in an FDD communication system, and includes:

[0077] Step 210: Receive uplink time domain configuration.

[0078] Among them, the proportion of uplink time units in the uplink time domain configuration is less than 100%.

[0079] In some embodiments, the FDD communication system is an FDD satellite communication system.

[0080] In FDD satellite communication systems, uplink (from the terminal device to the satellite) and downlink (from the satellite to the terminal device) data transmissions are performed simultaneously via two different frequency channels. This method allows uplink and downlink data to be transmitted concurrently, improving data transmission efficiency.

[0081] Figure 3 shows a schematic diagram of uplink and downlink resources for an FDD communication system provided in related technologies.

[0082] As shown in Figure 3, within this time slot, for the uplink time domain configuration, the entire time slot consists entirely of uplink symbols. Similarly, for the downlink time domain configuration, the entire time slot consists entirely of downlink symbols.

[0083] However, for satellite communication terminal equipment, if the uplink time unit accounts for 100%, it is easy to cause SAR to exceed the limit. Therefore, it is necessary to reduce the proportion of uplink time units to avoid the SAR exceeding the limit problem.

[0084] In some embodiments, the uplink time domain configuration includes at least one of the following: the proportion of uplink time units; a time unit pattern within a time domain range, the time unit pattern including at least one type and arrangement of time units; wherein, the type of time unit includes uplink time units and empty time units, and the granularity of the time unit is at least one of symbol, symbol group, time slot, subframe, and frame.

[0085] For example, when the uplink time domain configuration includes the proportion of uplink subframes (uplink time units), it is used to indicate that the proportion of uplink subframes is 40%, 3 / 7, 4 / 14, etc.; or, when the uplink time domain configuration includes a symbol pattern (time unit pattern) within a time slot, it is used to indicate that the 1st to 3rd symbols and the 8th to 10th symbols within a time slot are uplink symbols, and the 4th to 7th symbols and the 11th to 14th symbols are empty symbols. For example, if 1 represents an uplink symbol and 0 represents an empty symbol, then the symbol pattern within the above time slot can be represented as 11100001110000.

[0086] By representing the uplink time domain configuration in different ways, configuration requirements can be flexibly met according to different usage scenarios.

[0087] To address the aforementioned SAR overshooting issue, further division of the uplink time slots is required. Figure 4 illustrates a schematic diagram of a resource allocation method provided in an exemplary embodiment of this application.

[0088] As shown in Figure 4(a), the uplink time slot is divided into uplink pattern 1 (UL pattern 1) and uplink pattern 2 (UL pattern 2). Uplink pattern 1 accounts for 1% of the entire time slot, and uplink pattern 2 accounts for 2% of the entire time slot. There are many other ways to divide the uplink pattern. This embodiment is only used as an example to illustrate uplink pattern 1 and uplink pattern 2, and is not limited thereto.

[0089] As shown in Figure 4(b), for cell 1, uplink pattern 1 is used to indicate that the first to third symbols and the eighth to tenth symbols in this time slot are uplink symbols, and the fourth to seventh symbols and the eleventh to fourteenth symbols are empty symbols. That is, the proportion of uplink symbols is 42.9% (3 / 7), which is less than 100%.

[0090] As shown in Figure 4(c), for cell 2, uplink pattern 2 is used to indicate that the 4th to 7th symbols and the 11th to 14th symbols in this time slot are uplink symbols, and the 1st to 3rd symbols and the 8th to 10th symbols are empty symbols. That is, the proportion of uplink symbols is 57.1% (4 / 7), which is less than 100%.

[0091] In some embodiments, the method further includes: receiving a downlink time domain configuration, wherein the proportion of downlink time units in the downlink time domain configuration is equal to 100%; or, receiving a downlink time domain configuration, wherein the proportion of downlink time units in the downlink time domain configuration is less than 100%; or, receiving a downlink time domain configuration, wherein the proportion of downlink time units in the downlink time domain configuration is less than 100%, and for the same cell or beam, the downlink time units and uplink time units occupy the same number of time units.

[0092] Since downlink time slots have no impact on the SAR of the terminal device, the original time slot configuration (i.e., the configuration shown in Figure 3) can be maintained, or the same pattern division method as the uplink time slots can be adopted. Figure 5 shows a schematic diagram of a resource configuration method provided by an exemplary embodiment of this application.

[0093] As shown in Figure 5(a), the downlink time slot is divided into downlink pattern 1 (DL pattern 1) and downlink pattern 2 (DL pattern 2). Downlink pattern 1 accounts for 1% of the entire time slot, and downlink pattern 2 accounts for 2% of the entire time slot.

[0094] As shown in Figure 5(b), for cell 1, downlink pattern 1 is used to indicate that the first to third symbols and the eighth to tenth symbols in this time slot are downlink symbols, and the fourth to seventh symbols and the eleventh to fourteenth symbols are empty symbols, that is, the proportion of downlink symbols is 42.9% (3 / 7).

[0095] As shown in Figure 5(c), for cell 2, downlink pattern 2 is used to indicate that the 4th to 7th symbols and the 11th to 14th symbols in this time slot are downlink symbols, and the 1st to 3rd symbols and the 8th to 10th symbols are empty symbols, that is, the proportion of downlink symbols is 57.1% (4 / 7).

[0096] Optionally, the division and combination of the upward and downward patterns are shown in Table 3. The combinations in Table 3 are only illustrative examples, and the embodiments of this application do not limit other combinations.

[0097] Table 3

[0098] For example, combination 1 is a combination of uplink pattern 1 and downlink pattern 1, as shown in Figure 5(b); combination 2 is a combination of uplink pattern 2 and downlink pattern 2, as shown in Figure 5(c); combination 4 is a combination of uplink pattern 1 and all downlink time slots, as shown in Figure 4(b); combination 4 is a combination of uplink pattern 2 and all downlink time slots, as shown in Figure 4(c).

[0099] This embodiment uses the division of time slots as an example. In other embodiments, the division can also be based on other granularities such as symbol groups, subframes, and frames. This application does not limit this.

[0100] The following explanation uses an FDD satellite communication system as an example; the same methods apply to FDD terrestrial communication systems.

[0101] Different neighborhoods correspond to different uplink patterns:

[0102] In some embodiments, the uplink time domain configuration is per cell or cell-level.

[0103] Different uplink patterns are mapped to different cells, and the terminal device selects the appropriate uplink pattern to access the corresponding cell.

[0104] Optionally, the uplink time domain configuration corresponds to one cell (e.g., the first cell), and other cells do not use the uplink time domain configuration; or, the uplink time domain configuration corresponds to at least two cells.

[0105] In some embodiments, at least two cells have different uplink time domain configurations; or, the uplink time units in the uplink time domain configurations of at least two cells do not overlap in the time domain.

[0106] Figure 6 illustrates a schematic diagram of different uplink patterns corresponding to different cells, provided in an exemplary embodiment of this application. As shown in Figure 6, in this example, different uplink patterns (the downlink patterns of the two satellite cells can be the same or different) correspond to different cells. For example, satellite cell 1 corresponds to uplink pattern 1 with an uplink time unit ratio of 1, and satellite cell 2 corresponds to uplink pattern 2 with an uplink time unit ratio of 2. In this embodiment, a satellite cell can be simply referred to as a cell.

[0107] Optionally, the proportion of uplink time units in the uplink time domain configuration of at least two cells is different in the time domain; and / or, the total proportion of uplink time units in the uplink time domain configuration of at least two cells is less than or equal to 100%.

[0108] For example, combining Figures 4 and 6, the proportion of uplink symbols in the time slots in the uplink time domain configuration of satellite cell 1 is 42.9%, while the proportion of uplink symbols in the time slots in the uplink time domain configuration of satellite cell 2 is 57.1%. The proportions are different, but the total proportion is equal to 100%.

[0109] This embodiment uses a time slot as an example. In other embodiments, it can also be described based on other granularities such as symbol groups, subframes, and frames. This application does not limit this.

[0110] In some embodiments, the uplink time domain configuration is carried in at least one of the Master Information Block (MIB), System Information Block (SIB), and Radio Resource Control (RRC) signaling.

[0111] Optionally, RRC signaling includes public RRC signaling, terminal equipment-specific RRC signaling, and terminal equipment group RRC signaling;

[0112] Specifically, the terminal device-specific RRC signaling is only for that terminal device, while the terminal device group RRC signaling is for a terminal device group, which includes that terminal device.

[0113] To inform terminal devices of the proportion of uplink time units corresponding to each satellite cell, the uplink pattern needs to be communicated to the terminal devices. For example, the uplink time domain configuration is broadcast via MIB, SIB1, or SIBx (x is greater than 1). The uplink time domain configuration includes at least one of the following: the proportion of uplink time units (in units of symbols, time slots, subframes, or frames); and a time unit pattern within a time domain range, wherein the time unit pattern includes at least one type and arrangement of time units.

[0114] For example, the arrangement of symbols within a time slot, such as DDDNNNNDDDNNNN, where D represents the uplink symbol and N represents the empty symbol, can be represented by 11100001110000 in a specific implementation.

[0115] For example, the arrangement of time slots within a subframe, such as DN, where D represents uplink time slots and N represents empty time slots, can be represented by 10 in the specific implementation.

[0116] For example, the arrangement of subframes within a frame, such as DDDNNDDDNN, where D represents the uplink subframe and N represents the empty subframe, can be represented by 1110011100 in a specific implementation.

[0117] In some embodiments, the method further includes: accessing a first cell, the first cell being determined based on uplink time-domain configuration and / or the maximum uplink percentage supported by the terminal device.

[0118] In some embodiments, the maximum uplink percentage supported by the terminal device is greater than or equal to the uplink time unit percentage of the first cell.

[0119] This ensures that the terminal device will not exceed its maximum uplink capacity in the first cell, thus enabling maximum power transmission.

[0120] As shown in Figure 6, the UE (terminal device) is located within the coverage area of ​​satellite cell 1 and satellite cell 2. The UE obtains the uplink time percentage corresponding to satellite cell 1 (percentage 1, 42.9%) by reading the uplink time domain configuration broadcast by the satellites, and obtains the uplink time percentage corresponding to satellite cell 2 (percentage 2, 57.1%). The UE compares this with its maximum supported uplink percentage to determine the appropriate first cell to connect to. For example, if the UE's maximum supported uplink percentage is 45%, which is greater than percentage 1 and less than percentage 2, then the UE can connect to satellite cell 1 to achieve maximum power transmission.

[0121] Different beams correspond to different uplink patterns:

[0122] In some embodiments, the uplink time-domain configuration is per beam or based on beam granularity.

[0123] Different uplink patterns are mapped to different beams, and the terminal device selects the applicable uplink pattern to use the corresponding beam.

[0124] In some embodiments, the uplink time domain configurations of at least two beams are different; or, the uplink time units in the uplink time domain configurations of at least two beams do not overlap in the time domain.

[0125] Figure 7 illustrates a schematic diagram of different uplink patterns corresponding to different beams provided in an exemplary embodiment of this application. As shown in Figure 7, in this example, different uplink patterns (the downlink patterns of the two satellite beams may be the same or different) correspond to different beams. For example, satellite beam 1 corresponds to uplink pattern 1 with an uplink time unit ratio of 1, and satellite beam 2 corresponds to uplink pattern 2 with an uplink time unit ratio of 2. In this embodiment, the satellite beam can be simply referred to as a beam.

[0126] Optionally, the proportion of uplink time units in the uplink time domain configuration of at least two beams is different in the time domain; and / or, the total proportion of uplink time units in the uplink time domain configuration of at least two beams is less than or equal to 100% in the time domain.

[0127] In some embodiments, the method further includes using a first beam, which is determined based on uplink time-domain configuration and / or the maximum uplink percentage supported by the terminal device.

[0128] In some embodiments, the maximum uplink percentage supported by the terminal device is greater than or equal to the uplink time unit percentage of the first beam.

[0129] The UE (Terminal Equipment) selects the first beam based on the maximum uplink proportion it can support. Similar to the section on different uplink patterns for different cells, in order to let the UE know the proportion of uplink time units corresponding to each satellite beam, a system broadcast method can be used. For specific implementation details, please refer to the section on different uplink patterns for different cells mentioned above, which will not be repeated here.

[0130] The difference lies in the fact that in the embodiment of Figure 6, the uplink time ratio is limited based on cell granularity, and all beams in each cell correspond to the same uplink time ratio. In the embodiment of Figure 7, the uplink time ratio is distinguished based on beam granularity, and the implementation granularity is more refined. Different beams may correspond to different uplink time ratios, different beams may correspond to the same uplink time ratio, some beams may correspond to different uplink time ratios, and some beams may correspond to the same uplink time ratio.

[0131] In some embodiments, the relationship between the beam and the cell is one-to-one, many-to-one, or one-to-many.

[0132] When there is a one-to-one relationship between beams and cells, the embodiments in Figure 6 and Figure 7 can express the same meaning. When there is a many-to-one relationship between beams and cells, the two satellite cells in the embodiment of Figure 6 can correspond to the same beam. When there is a one-to-many relationship between beams and cells, the two satellite beams in the embodiment of Figure 7 can correspond to the same cell, and the two satellite beams can correspond to the same coverage area or different coverage areas.

[0133] Partitioning resources in the frequency and time domains:

[0134] In the above embodiments, resources are allocated in the time domain. Optionally, resources can also be allocated in the frequency domain for uplink transmission.

[0135] Figure 8 shows a schematic diagram of a resource configuration method provided in an exemplary embodiment of this application.

[0136] As shown in Figure 8(a), in frequency band 1, the uplink time slot is divided into uplink pattern 1 and uplink pattern 2, with uplink pattern 1 accounting for 1% of the total time slot and uplink pattern 2 accounting for 2%. In frequency band 2, the uplink time slot is divided into uplink pattern 3 and uplink pattern 4, with uplink pattern 3 accounting for 3% of the total time slot and uplink pattern 4 accounting for 4%.

[0137] As shown in Figure 8(b), for cell 1, uplink pattern 1 is used to indicate that in frequency band 1, the first to third symbols and the eighth to tenth symbols in this time slot are uplink symbols, and the fourth to seventh symbols and the eleventh to fourteenth symbols are empty symbols, that is, the proportion of uplink symbols is 42.9% (3 / 7).

[0138] As shown in Figure 8(c), for cell 2, uplink pattern 2 is used to indicate that in frequency band 1, the 4th to 7th symbols and the 11th to 14th symbols in this time slot are uplink symbols, and the 1st to 3rd symbols and the 8th to 10th symbols are empty symbols, that is, the proportion of uplink symbols is 57.1% (4 / 7).

[0139] As shown in Figure 8(d), for cell 3, uplink pattern 3 is used to indicate that in frequency band 2, the first to second symbols and the eighth to ninth symbols in this time slot are uplink symbols, and the third to seventh symbols and the tenth to fourteenth symbols are empty symbols, that is, the proportion of uplink symbols is 28.6% (2 / 7).

[0140] As shown in Figure 8(e), for cell 4, uplink pattern 4 is used to indicate that in frequency band 2, the 3rd to 7th symbols and the 10th to 14th symbols in this time slot are uplink symbols, and the 1st to 2nd symbols and the 8th to 9th symbols are empty symbols, that is, the proportion of uplink symbols is 71.4% (5 / 7).

[0141] Similarly, the same resource allocation method can be used for downlink time slots as for uplink time slots. For specific implementation details, please refer to the embodiment in Figure 5, which will not be repeated here.

[0142] By further dividing resources in the frequency domain, it is possible to more flexibly indicate the resources corresponding to different cells and improve data transmission efficiency.

[0143] This embodiment uses a time slot as an example. In other embodiments, it can also be described based on other granularities such as symbol groups, subframes, and frames. This application does not limit this.

[0144] In summary, the method provided in this embodiment avoids the SAR exceeding problem caused by the terminal device sending data for a long time by receiving the uplink time domain configuration, in which the proportion of uplink time units is less than 100%. Furthermore, the terminal device does not need to report its maximum supported uplink proportion to the network device; it only needs to receive the uplink time domain configuration sent by the network device. This method is simple to implement and reduces the power consumption of the terminal device.

[0145] The method provided in this embodiment also ensures that the terminal device will not exceed its maximum uplink ratio capability in the first cell (or first beam) by ensuring that the maximum uplink ratio supported by the terminal device is greater than or equal to the uplink time unit ratio of the first cell (or first beam), thereby enabling maximum power transmission.

[0146] The method provided in this embodiment further simplifies the scheme complexity or more accurately matches the uplink time units in the uplink time domain configuration by receiving downlink time domain configuration. For example, if the proportion of downlink time units in the downlink time domain configuration is equal to 100%, since downlink time slots have no impact on the SAR of the terminal device, not changing the proportion of downlink time units can simplify the scheme complexity. Alternatively, if the proportion of downlink time units in the downlink time domain configuration is less than 100%, and for the same cell or beam, the downlink time units and uplink time units occupy the same number of time units, it can more accurately match the uplink time units in the uplink time domain configuration.

[0147] Figure 9 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a terminal device in an FDD communication system and includes:

[0148] Step 910: Receive the first configuration.

[0149] The first configuration is used to instruct the terminal device to use the first resource, and the proportion of uplink time units in the uplink time domain configuration associated with the first resource is less than 100%.

[0150] In some embodiments, the FDD communication system is an FDD satellite communication system.

[0151] For satellite communication terminal equipment, if the uplink time unit accounts for 100%, it is easy to cause SAR exceeding the limit. Therefore, it is necessary to reduce the proportion of uplink time units to avoid the SAR exceeding the limit problem.

[0152] In some embodiments, the first configuration is carried in at least one of MIB, SIB, RRC signaling, Downlink Control Information (DCI), and Medium Access Control Control Element (MAC CE).

[0153] For example, the first configuration is carried in the RRC signaling. The first configuration is used to instruct the terminal device to use the first resource. The proportion of uplink time units in the uplink time domain configuration associated with the first resource is less than 100%.

[0154] In some embodiments, the method further includes: reporting terminal capability information, which is used to indicate the maximum uplink ratio supported by the terminal device.

[0155] In the embodiment shown in Figure 2, the terminal device does not need to report the maximum supported uplink percentage (maximum time unit percentage capability); this information is known only to the terminal device itself. The network device predefines multiple cells or beams with different uplink time unit percentages, and the terminal device selects the appropriate cell or beam based on the maximum supported uplink percentage. However, in this embodiment, the terminal device needs to report its terminal capability information, i.e., report the maximum supported uplink percentage, and the network device configures the terminal device to a cell or beam with a different uplink time unit percentage.

[0156] After the terminal device reports its capabilities, the network device matches the terminal device to a cell or beam with an uplink time unit ratio not exceeding the maximum uplink ratio supported by the terminal device, or to a portion of the resources within a cell or beam, based on that information. This simplifies the initial access process for the terminal device and allows the network device to more flexibly configure it to a suitable cell or beam.

[0157] In some embodiments, terminal capability information is carried in the UE Capability Information signaling.

[0158] In some embodiments, the first resource includes at least one of the following: a first cell; a first beam; transmission resources corresponding to the first cell; and transmission resources corresponding to the first beam.

[0159] Optionally, the first resource is determined by the network device based on the uplink time domain configuration and / or the maximum uplink percentage supported by the terminal device.

[0160] For example, the maximum uplink percentage supported by the terminal device is 45%, the uplink time percentage corresponding to cell 1 is 42.9%, and the uplink time percentage corresponding to cell 2 is 57.1%. Since 45% is greater than 42.9% and less than 57.1%, the network device determines that the first resource is the transmission resource corresponding to cell 1, and instructs the terminal device to use the transmission resource corresponding to cell 1 through the first configuration.

[0161] In some embodiments, the uplink time-domain configuration of the first resource association is per cell or cell-level.

[0162] In some embodiments, at least two cells have different uplink time domain configurations; or, the uplink time units in the uplink time domain configurations of at least two cells do not overlap in the time domain.

[0163] In some embodiments, the proportion of uplink time units in the uplink time domain configuration of at least two cells is different in the time domain; and / or, the total proportion of uplink time units in the uplink time domain configuration of at least two cells is less than or equal to 100%.

[0164] For specific implementation details, please refer to the embodiment shown in Figure 6, which will not be repeated here.

[0165] In some embodiments, the uplink time-domain configuration of the first resource association is per-beam or based on beam granularity.

[0166] In some embodiments, the uplink time domain configurations of at least two beams are different; or, the uplink time units in the uplink time domain configurations of at least two beams do not overlap in the time domain.

[0167] In some embodiments, the proportion of uplink time units in the uplink time domain configuration of at least two beams is different in the time domain; and / or, the total proportion of uplink time units in the uplink time domain configuration of at least two beams is less than or equal to 100% in the time domain.

[0168] For specific implementation details, please refer to the embodiment shown in Figure 7, which will not be repeated here.

[0169] In summary, the method provided in this embodiment avoids the SAR exceeding problem caused by the terminal device sending data for a long time by receiving a first configuration, which is used to instruct the terminal device to use a first resource. The proportion of uplink time units in the uplink time domain configuration associated with the first resource is less than 100%. Furthermore, it only needs to receive the first configuration sent by the network device, which is simple to implement and reduces the power consumption of the terminal device.

[0170] In the method provided in this embodiment, the first resource is determined by the network device based on the uplink time domain configuration and / or the maximum uplink ratio supported by the terminal device, which ensures that the terminal device will not exceed its maximum supported uplink ratio when transmitting data, thereby enabling maximum power transmission.

[0171] Figure 10 illustrates a flowchart of a communication method provided in an exemplary embodiment of this application. The method is executed by a terminal device in an FDD communication system and includes:

[0172] Step 1010: Use the first resource.

[0173] Among them, the proportion of uplink time units in the uplink time domain configuration associated with the first resource is less than 100%.

[0174] In some embodiments, the FDD communication system is an FDD satellite communication system.

[0175] For satellite communication terminal equipment, if the uplink time unit accounts for 100%, it is easy to cause SAR exceeding the limit. Therefore, it is necessary to reduce the proportion of uplink time units to avoid the SAR exceeding the limit problem.

[0176] In some embodiments, the first resource is carried in at least one of MIB, SIB, RRC signaling, DCI, and MAC CE.

[0177] For example, DCI is used to schedule a first resource, where the proportion of uplink time units in the uplink time domain configuration associated with the first resource is less than 100%.

[0178] In some embodiments, the first resource includes at least one of the following: a first cell; a first beam; transmission resources corresponding to the first cell; and transmission resources corresponding to the first beam.

[0179] Optionally, the first resource is determined by the terminal device based on the uplink time domain configuration and / or the maximum uplink percentage supported by the terminal device.

[0188] For specific implementation details, please refer to the embodiment shown in Figure 6, which will not be repeated here.

[0189] In some embodiments, the uplink time-domain configuration of the first resource association is per-beam or based on beam granularity.

[0191] In some embodiments, the proportion of uplink time units in the uplink time domain configuration of at least two beams is different in the time domain; and / or, the total proportion of uplink time units in the uplink time domain configuration of at least two beams is less than or equal to 100% in the time domain.

[0192] For specific implementation details, please refer to the embodiment shown in Figure 7, which will not be repeated here.

[0193] In some embodiments, the proportion of downlink time units in the downlink time domain configuration of the FDD communication system is equal to 100%; or, the proportion of downlink time units in the downlink time domain configuration of the FDD communication system is less than 100%; or, the proportion of downlink time units in the downlink time domain configuration of the FDD communication system is less than 100%, and for the same cell or beam, the downlink time units and uplink time units occupy the same number of time units.

[0194] For specific implementation details, please refer to the embodiment shown in Figure 2, which will not be repeated here.

[0195] In summary, the method provided in this embodiment avoids the SAR exceeding problem caused by the terminal device sending data for a long time by using a first resource, where the proportion of uplink time units in the uplink time domain configuration associated with the first resource is less than 100%.

[0196] In the method provided in this embodiment, the first resource is determined by the network device based on the uplink time domain configuration and / or the maximum uplink ratio supported by the terminal device, which ensures that the terminal device will not exceed its maximum supported uplink ratio when transmitting data, thereby enabling maximum power transmission.

[0197] Figure 11 shows a flowchart of a resource configuration method provided in an exemplary embodiment of this application. The method is executed by a network device in an FDD communication system and includes:

[0198] Step 1110: Send uplink time domain configuration.

[0199] Among them, the proportion of uplink time units in the uplink time domain configuration is less than 100%.

[0200] In some embodiments, the FDD communication system is an FDD satellite communication system.

[0201] In some embodiments, the uplink time domain configuration includes at least one of the following: the proportion of uplink time units; a time unit pattern within a time domain range, the time unit pattern including at least one type and arrangement of time units; wherein, the type of time unit includes uplink time units and empty time units, and the granularity of the time unit is at least one of symbol, symbol group, time slot, subframe, and frame.

[0202] To address the aforementioned SAR overshooting issue, further division of the uplink time slots is required. Figure 4 illustrates a schematic diagram of a resource allocation method provided in an exemplary embodiment of this application.

[0203] For specific implementation details, please refer to the embodiment shown in Figure 4, which will not be repeated here.

[0204] In some embodiments, the method further includes: sending downlink time domain configuration, wherein the proportion of downlink time units in the downlink time domain configuration is equal to 100%; or, sending downlink time domain configuration, wherein the proportion of downlink time units in the downlink time domain configuration is less than 100%; or, sending downlink time domain configuration, wherein the proportion of downlink time units in the downlink time domain configuration is less than 100%, and for the same cell or beam, the downlink time units and uplink time units occupy the same number of time units.

[0205] Since downlink time slots have no impact on the SAR of the terminal device, the original time slot configuration (i.e., the configuration shown in Figure 3) can be maintained, or the same pattern division method as the uplink time slots can be adopted. Figure 5 shows a schematic diagram of a resource configuration method provided by an exemplary embodiment of this application. Specific implementation details are given in the embodiment shown in Figure 5, and will not be repeated here.

[0211] Different uplink patterns are mapped to different cells, and the terminal device selects the appropriate uplink pattern to access the corresponding cell.

[0212] Optionally, the uplink time domain configuration corresponds to one cell (e.g., the first cell), and other cells do not use the uplink time domain configuration; or, the uplink time domain configuration corresponds to at least two cells.

Furthermore, it does not require the network device to count the proportion of uplink time units of the terminal device in real time, thus reducing the implementation complexity.

This method enables simultaneous transmission of uplink and downlink data, improving data transmission efficiency.

[0266] Since the downlink time slots have no impact on the SAR of the first device, the original time slot configuration (i.e., the configuration shown in Figure 3) can be maintained, or the same pattern division method as the uplink time slots can be adopted. Figure 5 shows a schematic diagram of a resource configuration method provided by an exemplary embodiment of this application.
