Description

Communication method, apparatus and system TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and more particularly, to a communication method and apparatus. BACKGROUND

[0002] To solve the problems of less uplink time slots in the existing TDD system, leading to large uplink time delay, limited uplink coverage, and the like, the Rel-19 standard introduces a subband full duplex (SBFD) technical solution for the TDD system. In the SBFD technical solution, one carrier can be divided into a plurality of subbands with different link directions, and a base station can simultaneously transmit a signal on a downlink subband and receive a signal on an uplink subband, which can reduce the uplink time delay and improve the uplink coverage. However, the SBFD introduces interference between different links, for example, a downlink signal transmitted by one base station on a downlink subband can interfere with an uplink signal received by another base station on an uplink subband, which is referred to as inter-site cross-link interference. In order to manage the inter-site cross-link interference, the base station needs to perform interference or channel measurement on the inter-site cross-link interference. However, the uplink transmission of the base station can affect the inter-site cross-link interference or channel measurement, affecting the accuracy of the inter-site cross-link interference or channel measurement.

[0083] Optionally, the AI nodes can be deployed in one or more of the following positions in the communication system: a radio access network device, a terminal device, or a core network device, etc., or the AI nodes can also be deployed separately, for example, in a position other than any of the above devices, such as a host or a cloud server of an over the top (OTT) system. The AI nodes can communicate with other devices in the communication system, which can be one or more of the following: a network device, a terminal device, or a network element of a core network, etc.

[0084] It can be understood that the present application does not limit the number of AI nodes. For example, when there are multiple AI nodes, the multiple AI nodes can be divided based on functions, such as different AI nodes being responsible for different functions.

[0085] It can also be understood that the AI nodes can be independent devices, can be integrated into the same device to implement different functions, or can be network elements in a hardware device, or software functions running on a dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform), and the present application does not limit the specific form of the AI nodes.

[0086] The AI nodes can be AI network elements or AI modules.

[0087] FIG. 3 is a schematic diagram of a possible application framework in a communication system. As shown in FIG. 3, network elements in the communication system are connected through interfaces (e.g., NG, Xn, Fl) or air interfaces. One or more AI modules (only one is shown in FIG. 3 for clarity) are deployed in one or more of the network element nodes, such as one or more of the core network devices, access network nodes (RAN nodes), terminals, or operation administration and maintenance (OAM) devices. The access network node can be a single RAN node or can include multiple RAN nodes, e.g., including a CU and a DU. The CU and / or the DU can also be deployed with one or more AI modules. Optionally, the CU can be further split into a CU-CP and a CU-UP. One or more AI modules are deployed in the CU-CP and / or the CU-UP.

[0088] The AI module is configured to implement a corresponding AI function. AI modules deployed in different network elements can be the same or different. An AI module can implement different functions according to different parameter configurations of the model of the AI module. The model of the AI module can be configured based on one or more of the following parameters: a structural parameter (e.g., at least one of a number of neural network layers, a width of a neural network, a connection relationship between layers, a weight of a neuron, an activation function of a neuron, or a bias in the activation function), an input parameter (e.g., a type of the input parameter and / or a dimension of the input parameter), or an output parameter (e.g., a type of the output parameter and / or a dimension of the output parameter). The bias in the activation function can also be referred to as a bias of the neural network.

[0089] An AI module can have one or more models. A model can infer an output including one parameter or multiple parameters. The learning process, the training process, or the inference process of different models can be deployed in different nodes or devices, or can be deployed in the same node or device.

[0090] Fig. 4 is a schematic diagram of another possible application framework in a communication system. As shown in Fig. 4, a RAN intelligent controller (RIC) is included in the communication system. For example, the RIC can be the AI module 117, 118 shown in Fig. 4, which is configured to implement AI-related functions. The RIC includes a near-real time RIC (near-RT RIC) and a non-real time RIC (Non-RT RIC). The non-real time RIC is mainly configured to process non-real time information, such as data that is not sensitive to latency, which can be in the order of seconds. The real time RIC is mainly configured to process near-real time information, such as data that is relatively sensitive to latency, which can be in the order of tens of milliseconds.

[0091] The near-real time RIC is configured to perform model training and inference. For example, the near-real time RIC is configured to train an AI model and perform inference using the AI model. The near-real time RIC can obtain network side and / or terminal side information from a RAN node (e.g., a CU, a CU-CP, a CU-UP, a DU, and / or a RU) and / or a terminal. The information can be used as training data or inference data. Optionally, the near-real time RIC can deliver inference results to the RAN node and / or the terminal. Optionally, the inference results can be exchanged between the CU and the DU, and / or between the DU and the RU. For example, the near-real time RIC delivers the inference results to the DU, which then delivers the inference results to the RU.

[0092] The non-real time RIC is also configured to perform model training and inference. For example, the non-real time RIC is configured to train an AI model and perform inference using the AI model. The non-real time RIC can obtain network side and / or terminal side information from a RAN node (e.g., a CU, a CU-CP, a CU-UP, a DU, and / or a RU) and / or a terminal. The information can be used as training data or inference data, and the inference results can be delivered to the RAN node and / or the terminal. Optionally, the inference results can be exchanged between the CU and the DU, and / or between the DU and the RU. For example, the non-real time RIC delivers the inference results to the DU, which then delivers the inference results to the RU.

[0093] The near-real time RIC and the non-real time RIC can also be separately configured as a network element. Alternatively, the near-real time RIC and the non-real time RIC can also be part of other devices. For example, the near-real time RIC can be configured in a RAN node (e.g., a CU, a DU), and the non-real time RIC can be configured in an OAM, a cloud server, a core network device, or another network device.

[0094] Embodiments of the present application can be applied to a 5G new radio (NR) wireless communication system, and high data rate and low latency are achieved by using a large bandwidth. In a time division duplex system, as shown in FIG. 5, DL usually occupies the main time resource, which causes coverage imbalance between DL and UL. Compared with a frequency division duplex (FDD) system, the uplink coverage of a TDD system is poorer and the delay is larger.

[0095] To solve the problems of uplink coverage and uplink delay in a TDD system, a SBFD scheme is proposed in release (R) 18 standards. In the SBFD scheme, one component carrier (CC) can include multiple subbands, and the transmission directions of different subbands can be different.

[0096] For example, FIG. 6 is a schematic diagram of time-frequency resource allocation in a SBFD scheme. On the three time units in the middle, one carrier can be divided into three subbands, the middle subband is an uplink subband that can be used for uplink transmission, and is identified as UL in the figure. The upper and lower subbands are downlink subbands that can be used for downlink transmission, and are identified as DL in the figure. Whether there is a guard band (GB) between the downlink subband and the uplink subband, and whether transmission can be performed on the guard band if the guard band exists, are not limited by the present application.

[0097] Among them, the upper subband refers to the subband with a higher frequency, the lower subband refers to the subband with a lower frequency, and the middle subband refers to the subband with a frequency between the frequency of the upper subband and the frequency of the lower subband. The first or last time unit can be referred to as a non-SBFD time unit, and any time unit in the middle can be referred to as a SBFD time unit. The time unit may, for example, be a time slot or a symbol.

[0098] For another example, FIG. 7 is a schematic diagram of time-frequency resource allocation in a SBFD scheme. On the three time units in the middle, one carrier can be divided into two subbands, the upper subband is a downlink subband that can be used for downlink transmission, and is identified as DL in the figure. The lower subband is an uplink subband that can be used for uplink transmission, and is identified as UL in the figure.

[0099] It can be considered that in the SBFD scheme, on the SBFD time unit, the network device can realize simultaneous sending and receiving signals through different frequency domain resources or subbands. At present, in the R19 standard, the network device can adopt a subband full duplex scheme, and the terminal device can adopt a subband half duplex scheme. The terminal device adopts a subband half duplex scheme, which means that the terminal device can only receive or send signals on the SBFD time unit, and cannot simultaneously receive and send signals.

[0100] For the time domain configuration of SBFD, there are two possible configuration modes according to whether SBFD symbols and non-SBFD symbols are contained in one time slot at the same time. In one possible configuration mode, the time domain configuration of SBFD is time slot level, that is, the symbols contained in one time slot are all configured as SBFD symbols or all configured as non-SBFD symbols. In another possible configuration mode, the time domain configuration of SBFD is symbol level, that is, the symbols contained in one time slot can be configured as SBFD symbols and the other part can be configured as non-SBFD symbols. The embodiments of the present application do not make any limitation on the time domain configuration mode of SBFD. Among them, the SBFD symbol can be a symbol configured with SBFD operation, and the non-SBFD symbol can be a symbol without SBFD operation. For uplink transmission, the non-SBFD symbol can be an uplink symbol or a flexible symbol; for downlink transmission, the non-SBFD symbol can be a downlink symbol or a flexible symbol.

[0101] Compared with the TDD system, in the SBFD scheme, the available uplink transmission resources of the terminal device are increased. Therefore, the SBFD scheme can effectively improve the uplink coverage and reduce the uplink delay.

[0102] In the SBFD scheme, due to the signal power in one subband leaking into adjacent other subbands, it will cause interference between UL and DL, that is, cross link interference (CLI). According to the source of the interference, the CLI can be divided into the following two types:

[0103] 1) Type 1, UE-to-UE CLI.

[0104] UE-to-UE CLI refers to the interference caused by the uplink signal transmitted by one UE in the cell to the downlink signal received by another UE in the cell or in the neighboring cell. For example, in FIG. 8, the interference caused by the uplink signal transmitted by UE#1 or UE#2 to the downlink signal received by UE#0 from gNB#0 can be referred to as UE-to-UE CLI. The embodiments of the present application mainly measure and report the UE-to-UE CLI.

[0105] 2) Type 2, CLI between next generation nodeB (gNB) and gNB (gNB-to-gNB CLI).

[0106] gNB-to-gNB CLI refers to the interference caused by the downlink signal transmitted by one base station to the uplink signal received by another base station. For example, in FIG. 8, the interference caused by the downlink signal transmitted by gNB#0 to UE#0 to the uplink signal received by gNB#1 from UE#1 or UE#2 can be referred to as gNB-to-gNB CLI.

[0107] FIG. 10 shows a schematic diagram of a flexible TDD scenario according to an embodiment of the present application.

[0108] Dynamic / flexible TDD supports different cells using different uplink and downlink time slot ratios, and supports dynamic changes of the uplink and downlink time slot ratios. For example, as shown in FIG. 9, cell 1 uses the uplink and downlink time slot ratio of DDDSU, and cell 2 uses the uplink and downlink time slot ratio of DSUUU. If base station 1 and base station 2 are synchronized, in time slot 3, the downlink signal transmitted by base station 1 will cause interference to the uplink signal received by base station 2, which can be considered as CLI between base stations.

[0109] The design of uplink mute resources, the configuration method and the power transmission method of uplink non-mute resources according to the embodiments of the present application will be described in detail below in combination with FIGS. 1-9.

[0110] FIG. 10 shows a schematic diagram of a first resource according to an embodiment of the present application.

[0111] In the NR system, taking FIG. 10 as an example, when the subcarrier spacing is 15 kHz, in the time domain, the length of each slot is 1 millisecond (ms), occupying 14 orthogonal frequency division multiplexing (OFDM) symbols, as shown in FIG. 10, each slot occupies 0-13, a total of 14 OFDM symbols on the time axis. In the frequency domain, each slot occupies 12 consecutive subcarriers, as shown in FIG. 10, 0-11, a total of 12 subcarriers on the frequency axis. One resource block (RB) occupies one slot in time and 12 consecutive subcarriers in frequency, such as RB#X and RB#Y in FIG. 10. One resource element (RE) is the smallest unit of resources, that is, one OFDM symbol in time and one subcarrier in frequency.

[0112] Due to the existence of inter-base station CLI, inter-base station CLI needs to be measured and compensated to suppress the influence of inter-base station CLI on uplink transmission. The uplink transmission of the UE will have some influence on the inter-base station CLI or channel measurement, which will affect the accuracy of the inter-base station CLI or channel measurement, therefore, the uplink transmission of the UE needs to be muted on the measurement resource for inter-base station CLI or channel measurement, which is called first resource, or called uplink muting resource, both of which are equivalent. That is, the UE does not perform first uplink transmission on the first resource. The first resource is composed of one or more first resource elements, and the first resource element is a RE that is not used for first uplink transmission, that is, a muting RE.

[0113] The first uplink transmission herein can be a physical uplink share channel (PUSCH), and optionally, can also include a physical uplink control channel (PUCCH).

[0114] The first resource can be a protocol pre-defined pattern type in the frequency domain, or a pattern type configured by the base station through signaling. A specific embodiment is that the first resource is comb-2 mapping on the subcarrier, that is, occupying one subcarrier every two subcarriers, or occupying one subcarrier every interval subcarrier, which can also be considered that the first resource is located at the subcarriers with consecutive odd indexes, or the subcarriers with consecutive even indexes in the frequency domain. As shown in FIG. 10, on the RB#X, the first resource includes the consecutive odd subcarriers with indexes 1, 3, 5, 7, 9, and 11 in the frequency domain.

[0115] The first resource can be a protocol predefined pattern type in the time domain, or a pattern type configured by the base station through signaling. A specific embodiment is that the first resource occupies at most two symbols in a slot. For example, one symbol is located in the first three symbols in the slot, and the other symbol is located in the remaining symbols, that is, the fourth and subsequent time domain symbols. In this way, the first resource is located in the time-frequency resource range of the PDCCH and PDSCH respectively, enabling the base station to measure the interference caused by the PDCCH and PDSCH respectively, improving the accuracy of interference measurement, and improving the system performance. For example, for PUSCH mapping type A, the time domain symbol of the first resource can be located in the first symbol in the slot, or the first valid symbol after the demodulation reference signal (DMRS) symbol, that is, the symbol that can be used for the first uplink transmission. The time domain symbol of the first resource can be located in the first symbol in the slot and the first valid symbol after the DMRS symbol. For another example, for PUSCH mapping type B, the time domain symbol of the first resource can be located in the second symbol, or the third symbol, or the fourth symbol in the slot. The time domain symbol of the first resource can be located in the second symbol and the fourth symbol in the slot, or the time domain symbol of the first resource can be located in the third symbol and the fourth symbol in the slot.

[0116] Specifically, in a slot, there are different meanings about the first three symbols, which are located in different positions in the slot for different reference starting points. For example, taking the first symbol of the slot as the reference starting point of the time domain symbol, the base station configures the first resource to be located in the second symbol, regardless of which symbol in the slot the PUSCH transmission starts from, the uplink muting resource is located in the second symbol of the slot. For another example, taking the starting symbol of the PUSCH as the reference starting point of the time domain symbol, the base station configures the first resource to be located in the second symbol, if the PUSCH transmission starts from the third symbol in the slot, the first resource is located in the second symbol relative to the starting symbol (third symbol) of the PUSCH transmission, that is, the first resource is located in the fourth symbol of the slot.

[0117] Optionally, for PUSCH mapping type A, the reference starting point of the time domain symbol can be the first symbol of the slot, and for PUSCH mapping type B, the reference starting point of the time domain symbol can be the starting symbol of the PUSCH.

[0118] For time-domain configuration of SBFD, there are two possible configuration manners according to whether SBFD symbols and non-SBFD symbols are contained in one slot. In one possible configuration manner, the time-domain configuration of SBFD is slot-level, that is, the symbols contained in one slot are configured as SBFD symbols or non-SBFD symbols. In another possible configuration manner, the time-domain configuration of SBFD is symbol-level, that is, the symbols contained in one slot are configured as SBFD symbols or non-SBFD symbols. The first resource unit in the first resource is valid only on the SBFD symbol.

[0119] For example, if the symbols contained in one slot are all non-SBFD symbols, even if the base station configures the first resource on the slot, the first resource is not valid on the slot, that is, the first resource unit is not valid. For another example, if the symbols contained in one slot are partially SBFD symbols and partially non-SBFD symbols, and the base station configures the first resource on the slot, the first resource unit configured on the non-SBFD symbols is not valid, and the first resource unit configured on the SBFD symbols is valid. For another example, for PUSCH transmission across multiple slots, for example, PUSCH repeated transmission across multiple slots, or PUSCH transmission mapping a transport block (TB) across multiple slots, or multiple PDSCH transmissions scheduled by one DCI on multiple slots, similarly, only the first resource unit configured on the SBFD slot or SBFD symbol is valid.

[0120] Optionally, the first resource cannot be configured on a symbol containing a PUSCH DMRS or a phase-tracking reference signal (PT-RS) or a sounding reference signal (SRS). Or, if the first resource is configured on a symbol containing a PUSCH DMRS or a PUCCH DMRS or a PT-RS or an SRS, the first resource on the symbol is invalid.

[0121] Optionally, the first resource can be located in one slot or multiple slots. When the first resource is located in multiple slots, the pattern on each slot can be the same or different.

[0122] FIG. 11 shows a flowchart of an uplink muting resource configuration method provided by an embodiment of the present application, including the following steps:

[0123] Step S1101, the network device sends first signaling to the terminal device. Correspondingly, the terminal device receives the first signaling from the network device.

[0124] Optionally, the first signaling can be radio resource control (RRC) signaling or system information block (SIB).

[0125] The base station configures N sets of first resources for the UE through the first signaling, where N is a positive integer greater than or equal to 1. The first resources are not used for the first uplink transmission, and thus the first resources can also be referred to as uplink muting resources. The first uplink transmission can be PUSCH. Optionally, the first uplink transmission can also be PUCCH.

[0126] The first resources can be of a BWP-specific type, or a UE-specific type, or a cell-specific type. For example, only one of the N sets is of a BWP-specific type, and the remaining N-1 sets are of a UE-specific type.

[0127] For example, if the first resources are of a BWP-specific type or a BWP group-specific type, the first resources are independently configured for each BWP or BWP group. Optionally, the first resources are configured for some BWPs or BWP groups, and the first resources are not configured for other BWPs or BWP groups. The first resources are valid only for the associated BWPs or BWP groups, and are not valid for other unassociated BWPs or BWP groups.

[0128] For example, if the first resources are of a UE-specific type, the first resources are valid for all BWPs of the UE.

[0129] For example, if the first resources are of a cell-specific type or a cell-common type, the first resources are valid for all BWPs of all UEs in the cell.

[0130] Step S1102, the network device sends second signaling to the terminal device. Correspondingly, the terminal device receives the second signaling from the network device.

[0131] S1102 is an optional step. The base station can dynamically activate / deactivate the first resources as needed. For example, if the inter-station CLI is small, or in other words, the inter-station CLI has a small impact on the uplink transmission, the base station can deactivate the first resources, so as to avoid the impact of the resource overhead of the uplink muting resources on the uplink transmission, and improve the flexibility of the base station scheduling. In this patent application, activation and taking effect are the same meaning, and deactivation and not taking effect are the same meaning, and any substitution can be made.

[0132] Optionally, the base station can indicate N1 sets of the first resources are valid or activated through the second signaling when indicating the validity or activation. N1 is less than or equal to N, and N1 is a positive integer. Optionally, the base station can divide the N sets of the first resources into N2 sets of first resource groups, N2 is less than or equal to N, and N2 is a positive integer. Each first resource group contains one or more sets of first resources, and the base station can indicate that one of the first resource groups is valid or activated.

[0133] Optionally, the base station can indicate that all the first resources in the N sets of the first resources are not valid or activated through the second signaling. The base station can also not make one or more of the first resources or first resource groups valid or activated, which can be referred to in the above indication of validity or activation.

[0134] The second signaling can be downlink control information (DCI) or a MAC control element (MAC CE).

[0135] The DCI can be scheduling DCI, such as DCI that schedules PUSCH, for example, DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 0_3, etc. Specifically, a new indication field can be introduced in these DCI formats to indicate the above functions, or some existing indication fields can be multiplexed to indicate the above functions, such as the sounding reference signal request (SRS request) field, the time domain resource allocation (TDRA) field, the modulation and coding scheme (MCS) field, etc.

[0136] 1. Multiplexing SRS request field

[0137] The existing SRS request field is used to trigger aperiodic SRS, and the indication field includes 2 bits or 3 bits.

[0138] In an embodiment of the present application, part or all of the indication field can be used to indicate whether the first resource is activated or takes effect. For example, when the indication field includes two bits, the first bit is used to indicate whether the first resource is activated or takes effect, and the second bit is used to trigger aperiodic SRS, or both of the two bits are used to indicate whether the first resource is activated or takes effect. For another example, when the indication field includes three bits, the first bit is a supplementary uplink (SUL) / SUL indication, and the specific indication method can be referred to the prior art, and the second bit and / or the third bit are used to indicate whether the first resource is activated or takes effect. For another example, when the indication field includes three bits, the first bit indicates whether the indication field is used for first resource indication or aperiodic SRS indication, for example, when the first bit takes a value of '0', the second bit and the third bit are used to indicate aperiodic SRS indication, and the specific indication method can be referred to the prior art, and when the first bit takes a value of '1', the second bit and / or the third bit are used to indicate whether the first resource is activated or takes effect.

[0139] In another embodiment, one or more indication states of the indication field can be used to indicate whether the first resource is activated or takes effect. For example, when the SRS request field takes a value of '10' and / or '11', it indicates that the first resource is not activated / takes no effect, or indicates that the first resource is activated / takes effect, and the indication states corresponding to other values can be referred to the prior art.

[0140] 2. Multiplexing TDRA field

[0141] The existing TDRA field is used to indicate PUSCH time domain resource allocation. Specifically, the base station configures a PUSCH time domain resource allocation list through RRC signaling or other high layer signaling, the PUSCH time domain resource allocation list includes L PUSCH time domain resource allocation indications, L is a positive integer, and each PUSCH time domain resource allocation indication includes at least mapping type, starting symbol and length and other parameters, and the specific parameters can be referred to the prior art. The indication field includes bits, and the L values correspond to the L PUSCH time domain resource allocation indications one by one, so that the corresponding PUSCH time domain resource allocation information can be indicated through the TDRA field.

[0142] In the present application, indication information of whether the first resource is activated or takes effect can be introduced in each of the L PUSCH time domain resource allocation indications configured by the above RRC signaling or other high layer signaling, so that whether the first resource is activated / takes effect can be indicated through the TDRA field.

[0143] 3. Multiplexing MCS field

[0144] The existing MCS field is used to indicate the MCS of PUSCH, and the indication field includes 5 bits.

[0145] In the scheme of the present application, in one implementation, part or all of the bits in the indication field can be reused to indicate whether the first resource is activated or takes effect. For example, the first X bits of the indication field are used to indicate whether the first resource is activated or takes effect, and the remaining bits are still used to indicate the MCS, where X is a positive integer.

[0146] In another implementation, the MCS value of the indication field can be reused to indicate whether the first resource is activated or takes effect. For example, when the MCS value indicated by the indication field is greater than a first threshold, the first resource is not activated / takes effect, or when the MCS value indicated by the indication field is less than the first threshold, the first resource is activated / takes effect. Extending, the value of the first threshold can refer to the MCS threshold used to determine the time-domain density of the phase tracking reference signal (PT-RS) in the prior art, for example, ptrs-MCS3.

[0147] Optionally, the MAC CE can be used instead of the DCI to realize the indication, activation, etc. of the first resource.

[0148] Step S1103, the terminal device sends the first uplink transmission to the network device. Correspondingly, the network device receives the first uplink transmission from the terminal device.

[0149] Optionally, the network device performs measurement on the first resource, including inter-station cross-link interference or channel measurement.

[0150] In one specific implementation, before performing the first uplink transmission, the UE performs resource mapping, and if the scheduled or allocated time-frequency resource contains the first resource unit, the data of the first uplink transmission is not mapped to these first resource units. Optionally, according to the activation / taking effect indication information in the second signaling, the data of the first uplink transmission is not mapped to the activated / taking effect first resource units, but the data of the first uplink transmission can be mapped to the non-activated / non-taking effect first resource units.

[0151] The first value is the ratio of the energy per resource element (EPRE) of the first uplink transmission to the EPRE of the DMRS of the first uplink transmission.

[0152] One specific implementation, the UE keeps the uplink transmit power consistent on the symbols allocated for the first uplink transmission. If some of the symbols allocated for the first uplink transmission are configured with the first resource unit and some are not, the first value on the time-domain symbols configured with the first resource unit is greater than the first value on the time-domain symbols not configured with the first resource unit, where the first value is the ratio of the energy per resource element (EPRE) of the first uplink transmission to the EPRE of the DMRS of the first uplink transmission. The configuration can be pre-defined by the protocol or configured by the base station through signaling.

[0153] For the symbols configured with the first resource unit, the transmit power of the first transmission on the REs of these symbols needs to be boosted because there are fewer available REs on these symbols than on those not configured with the first resource unit. When the frequency-domain resource of the first resource is comb-2, the first value in the dB domain is equal to the first value on the time-domain symbols not including the first resource unit plus 3 dB. When the first value is in the linear domain, the first value on the time-domain symbols including the first resource unit is equal to twice the first value on the time-domain symbols not including the first resource unit.

[0154] For example, when the first uplink transmission is PUSCH, the PUSCH EPRE to DMRS EPRE ratio on the time-domain symbols not configured with the first resource unit can be determined according to Table 6.2.2-1 in 3GPP protocol TS 38.214 v18.0.0. For example, when the PUSCH EPRE to DMRS EPRE ratio on the time-domain symbols not configured with the first resource unit is 0 dB, the PUSCH EPRE to DMRS EPRE ratio on the time-domain symbols configured with the first resource unit is 3 dB.

[0157] It can be understood that, in order to realize the above functions, the terminal device or the network device comprises a hardware structure and / or a software module corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of the examples described in the embodiments disclosed in the present application, the present application can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is realized in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to realize the described functions for each specific application, but such implementation should not be considered beyond the scope of the present application.

[0158] The embodiments of the present application can divide the terminal device or the network device into function modules according to the above method embodiments, for example, each function module can be divided according to each function, or two or more functions can be integrated into one processing module. The integrated module can be realized in the form of hardware or in the form of a software function module.
