Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and apparatus for determining transmission power. Background Technology

[0002] In a communication system, terminal devices can send data to network devices through a physical uplink channel, thus achieving uplink communication. To ensure uplink communication performance, it is generally necessary to control the transmission power of the terminal devices to keep it within a reasonable range. By ensuring that the transmission power of the terminal devices is controlled within a reasonable range, both effective data transmission can be guaranteed, and interference to other devices can be minimized.

[0003] Therefore, how to control the transmission power within a reasonable range is an urgent problem to be solved. Summary of the Invention

[0004] This application provides a method and apparatus for determining transmission power, which can control the transmission power within a reasonable range.

[0005] In a first aspect, this application provides a method for determining transmission power, the method comprising:

[0006] A first transmission power is determined based on N time-domain resources corresponding to the first transmission block. The first transmission power is the transmission power of the first transmission block on each of the time-domain resources. The size of the N time-domain resources is greater than 1 time slot, and N is a positive integer. The first transmission block is transmitted on the N time-domain resources using the first transmission power.

[0007] In this embodiment, N is a positive integer, such as N=1, N=2, N=3, etc. This embodiment does not limit the value of N. The size of the N time-domain resources is greater than one time slot, which can be understood as: the length occupied by the N time-domain resources is greater than one time slot; or, the N time-domain resources are distributed across at least two time slots; or, the number of time slots occupied by the N time-domain resources is greater than one time slot. The N time-domain resources can be continuous or discontinuous.

[0008] It is understood that although the transmission power of each time domain resource is referred to as the first transmission power, whether the transmission power (i.e. the first transmission power) on each time domain resource is the same is not limited in the embodiments of this application.

[0009] It is understood that the above method can also be replaced by: determining a first transmission power based on N time-domain resources corresponding to the first signal, wherein the first transmission power is the transmission power on each of the time-domain resources, the size of the N time-domain resources is greater than 1 time slot, and N is a positive integer; and transmitting the first signal on the N time-domain resources using the first transmission power.

[0010] For example, the first signal may include a physical uplink shared channel (PUSCH), etc., and the specific type of the first signal is not limited in this embodiment. The description of the N time-domain resources and the first transmit power can be found in the above method and will not be detailed here.

[0011] In this embodiment, by associating the first transmission power with N time-domain resources corresponding to the transport block, the terminal device can determine the first transmission power based on these N time-domain resources, thereby ensuring that the first transmission power is controlled within a reasonable range and that the terminal device can reasonably control the transmission power. This improves the situation where the network device fails to receive the transport block, or it can also reduce interference with other terminal devices.

[0012] In one possible implementation, the N time-domain resources include K orthogonal frequency division multiplexing (OFDM) symbols, wherein the K OFDM symbols occupy at least two time slots, and K is a positive integer greater than 14.

[0013] In other words, the aforementioned K OFDM symbols are distributed across at least two time slots.

[0014] In one possible implementation, K is equal to 14, or K is a positive integer less than 14.

[0015] For example, the above N time-domain resources can be distributed across at least two time slots; however, the total length of the OFDM symbols included in the N time-domain resources can be equal to 14, or less than 14 (but greater than 2), etc.

[0016] In one possible implementation, the first transmit power is further determined based on at least one of the following: the frequency domain resources corresponding to the first transport block, the modulation order of the first transport block, the target coding rate of the first transport block, and the size of the first transport block.

[0017] In this embodiment of the application, the modulation order of the first transmission block (e.g., The modulation order can be used to determine the transmit power offset value (e.g., BPRE), etc. The target coding rate of the first transport block, such as the MCS of the first transport block (e.g., ... deltaMCS For example, the target coding rate can be used to determine the transmit power offset value (e.g., ...). The size of the first transmission block, such as the size of the code blocks it comprises, is also considered. For example, the size of the first transmission block can be used to determine a transmit power offset value (such as BPRE). In other words, the first transmit power can be determined not only by N, but also by one or more of the above.

[0018] In one possible implementation, the first transmission power satisfies the following formula:

[0027] It is understood that this application is for the convenience of indexing the carrier. To distinguish it from the cumulative power adjustment value of the transmission power of the first transmission block, this cumulative power adjustment value is used... This is a statement, but it should not be construed as a limitation on the embodiments of this application. For example, the It can also be used express.

[0046]

[0047] Wherein, C represents the number of code blocks corresponding to the first transport block, and the This represents the size of the r-th code block; This indicates the number of resource elements (REs) corresponding to the first transport block. The number of OFDM symbols in the s-th time-domain resource of the first transport block is determined by the number of OFDM symbols in the first transport block in the s-th time-domain resource, wherein the s-th time-domain resource is included in the N time-domain resources; or, the number of OFDM symbols in each of the N time-domain resources of the first transport block is determined by the number of OFDM symbols in the first transport block in each of the N time-domain resources. Configured by network devices, or defined by protocols, the This is the offset value.

After being output by the processor, the information may require further processing before reaching the transceiver. Similarly, when the processor receives the above information, the transceiver receives the information and inputs it into the processor.

[0107] Based on the terminal devices and network devices described above, embodiments of this application provide a communication system.

[0108] For example, terminal devices can communicate directly. This can be achieved, for instance, through D2D technology. Figure 1 As shown, UE4 and UE5, and UE4 and UE6, can communicate directly using D2D technology. UE4 or UE6 can communicate with UE5 individually or simultaneously.

[0112] 3. Subcarrier spacing

[0113] Subcarrier spacing is a set of parameters (also known as waveform parameters or numberology) in a communication system. This parameter set can be used to define one or more of the following parameters: subcarrier spacing, cyclic prefix (CP), time unit, bandwidth, etc. For example, CP information may include CP length and / or CP type. For instance, CP can be normal CP (NCP) or extended CP (ECP), etc. The time unit mentioned above represents a time unit in the time domain; for example, the time unit can be a sampling point, symbol, microslot, slot, subframe, or radio frame, etc. An example is the subcarrier spacing index. The relationship with subcarrier spacing can be shown in Table 1: Time unit information can include the type, length, or structure of the time unit. [TS 38.211, Table 4.2-1: Supported transmission numerologies] defines it as follows:

[0114] Table 1

[0115]

[0116] It is understood that the contents shown in Table 1 can also refer to relevant standards or protocols, such as TS 38.211, Table 4.2-1, etc., which will not be detailed here. It is understood that the subcarrier spacing shown above can also have other values, etc., and this application does not limit them.

[0117] The symbols defined below in this application are as follows: It can represent rounding up, or rounding up can also be done using ceil( () indicates etc. For example...

[0118] It is understood that the above descriptions of terminal equipment, network equipment, communication systems, or subcarrier spacing also apply to the various embodiments shown below. Further descriptions of terminal equipment, network equipment, communication systems, or subcarrier spacing will not be repeated below.

[0119] Figure 2 This is a flowchart illustrating a method for determining transmission power according to an embodiment of this application, as shown below. Figure 2 As shown, the method includes:

[0120] 201. The base station sends configuration information to the UE, and the UE receives the configuration information. This configuration information may include one or more of the following: the transmission power of the reference signal, time / frequency location (also known as time-domain resources / frequency-domain resources), or uplink power control. It can be understood that step 201 can be performed when the UE is connected to a downlink synchronization base station or an access base station, and the configuration information sent by the base station can be received.

[0121] For example, if the configuration information includes uplink power control information, then the configuration information may include cell common power control parameters and / or UE-specific power control parameters. If the UE is not configured with these dedicated power control parameters, the UE can use the cell common power control parameters to determine the uplink transmission power.

[0122] For example, the signaling format for the community common power control parameters can be as follows:

[0123]

[0124] Here, `PUSCH-ConfigCommon` represents the common configuration of the physical uplink shared channel (PUSCH). `msg3-DeltaPreamble` represents the power offset between message 3 (Msg3) and the random access preamble, and this power offset can be any number between -1 and 6. `p0-NominalWithGrant` represents the nominal P0 value corresponding to the PUSCH, and this nominal P0 value can be any number between -202 and 24. It can be understood that `OPTIONAL` above can indicate that the corresponding parameter can be configured or not. For example, the corresponding `msg3-DeltaPreamble` parameter or the corresponding `p0-NominalWithGrant` parameter can be configured, etc.

[0125] For example, the signaling format for UE-specific power control parameters can be as follows:

[0126]

[0127]

[0128] Here, tpc-Accumulation indicates whether transmit power control (TPC) is accumulated. For example, if this field is configured, the TPC value is considered to be accumulated. For example, this parameter can be used to determine the TPC value in formula (1). msg3-Alpha represents the weighting factor for Msg3 power control. p0-NominalWithoutGrant represents the nominal p0 value for semi-persistent scheduling or grant-free scheduling. p0-AlphaSets represents the possible set of p0 and alpha values ​​corresponding to PUSCH, such as the parameter used to determine the p0 value shown in formula (1). `pathlossReferenceRSToAddModList` is used to estimate the p0 value of the path loss reference signal corresponding to `PUSCH`. `deltaMCS` is the power adjustment enable corresponding to `MCS`, which can be used to determine the value shown in formula (1). For example, in 38.213, it can be written as P0-PUSCH-AlphaSet represents the possible set of p0 and alpha values ​​corresponding to PUSCH. This parameter can be used to determine the values ​​shown in formula (1). P0-PUSCH-AlphaSetId represents the set index of the p0 value and alpha value corresponding to PUSCH. P0 is the p0 value corresponding to PUSCH, and alpha is the alpha value corresponding to PUSCH.

[0129] It is understood that the nominal p0 value shown above can be considered as the reference target received power of PUSCH, while p0 in P0-PUSCH-AlphaSet can be considered as a power adjustment value specific to the UE. This p0 can be used for power control for different UEs.

[0130] 202. When the base station transmits a downlink reference signal at a specific transmission power, the UE receives the corresponding downlink reference signal.

[0131] It is understandable that the specific transmission power shown here refers to the transmission power corresponding to the base station.

[0132] Generally, reference signals (RS) can be further classified by function as demodulation reference signals (DMRS), channel state information reference signals (CSI-RS), phase tracking reference signals (PTRS), and sounding reference signals (SRS). For example, a reference signal is a signal whose time and frequency location, and the signal / symbol it carries in time and frequency, are known or can be inferred by the transmitting or receiving end according to predetermined rules. Reference signals are known signals used to acquire information about the effects of external factors (e.g., spatial channel conditions, non-ideals of transmitting or receiving devices) on the signal during transmission. Reference signals are generally used for channel estimation, auxiliary signal demodulation, and detection. For example, DMRS and CSI-RS are used to acquire channel information, while PTRS is used to acquire phase change information.

[0133] The downlink reference signal shown here is the reference signal sent by the base station to the UE.

[0134] Understandably, the base station can not only send downlink reference signals to the UE, but also engage in further uplink or downlink communication with the UE. For example, the base station can also perform signaling interaction, capability interaction, or security authentication with the UE. For instance, signaling may include uplink scheduling authorization, which specifies the time or frequency resources, modulation and coding scheme (MCS), or power control information required for uplink transmission. The MCS can be used to determine the modulation order and / or target coding rate of the data.

[0135] 203. The UE determines the transmission power of the uplink signal.

[0136] For example, the UE can determine the path loss (PL) between the base station and the UE based on the above configuration information and the reference signal received power (RSRP). The configuration information may include the p0 value of the reference signal used to estimate the path loss of the PUSCH.

[0137] For example, the UE can also determine the uplink signal transmission power based on the above configuration information and the above path loss, etc.

[0138] It is understandable that the method for the UE to determine the uplink signal transmission power can be found in the following text, such as formulas (1) to (4), etc., which will not be detailed here.

[0139] 204. The UE transmits uplink signals according to the determined transmission power. That is, the UE can perform uplink transmission via PUSCH.

[0140] The PUSCH can be used to carry data signals or control signals, etc., and this application embodiment does not limit this.

[0141] Furthermore, during the random access process, after the UE sends Random Access Message 1 (also known as Msg1), the base station sends a Random Access Response (also known as Message 2 or Msg2) to the UE. The Random Access Response (RAR) may carry an uplink grant (UL grant), which can be used to schedule uplink transmission messages. This message can be called Message 3 (also known as Msg3). In other words, Message 3 is uplink information sent by the UE to the base station and is a special type of information carried by the PUSCH. Therefore, the PUSCH shown in this embodiment can be used to carry Msg3.

[0142] It is understood that the following will explain the transmission power in conjunction with relevant standards or protocols. It is also understood that for any parts of the formulas shown below that are not described in detail, relevant standards or protocols can be consulted. This application's embodiments will not limit this further.

[0143] In new radio (NR), taking PUSCH as an example, when the UE performs uplink transmission, the power of the PUSCH can satisfy the following formula:

[0144]

[0145] in, This indicates the index of the active uplink bandwidth part (UL BWP). This indicates the carrier index (also known as the carrier index). This represents the serving cell index (also known as the index of the serving cell). This indicates the parameter set configuration index (also known as the parameter set configuration index). This indicates the PUSCH power control adjustment state index (also known as the PUSCH power control adjustment state index). This represents the PUSCH transmission occasion index (also known as the PUSCH transmission opportunity index). This represents the subcarrier spacing index (also known as the subcarrier spacing index).

[0146] It is understandable that the above formula (1) can be expressed as follows in relevant standards or protocols:

[0147] If the UE uses an indexed parameter set configuration and an indexed PUSCH power control adjustment state to transmit PUSCH on the active uplink bandwidth portion of the carrier of the serving cell, then the UE will determine the PUSCH transmission power in the PUSCH transmission scenario as described in the above formula (1). .

The English text in parentheses in the embodiments of this application can be understood as the representation in the corresponding standard or protocol, and this will not be repeated below. It is understood that the multiplication shown in this application can be [used for other purposes]. It can also be represented by a period.

[0149] Satisfy the following formula:

[0151] in, .

[0152] Regarding the above formula (2), if the UE establishes a dedicated radio resource control (RRC) connection through the Type-1 (i.e., four-step random access procedure) random access response procedure, and is not configured P0-PUSCH-AlphaSet Alternatively, it may send an uplink scheduling grant (UL grant) in the form of a random access response (RAR). .in The received target power of the preamble is indicated by higher-layer parameters configured by the base station. preambleReceivedTargetPower specified. It is the power offset between Random Access Message 3 (also known as Msg3) and the Random Access Preamble, determined by the configuration information. msg3-DeltaPreamble Specify, or if not configured, then .

[0153] Regarding formula (2) above, if the UE establishes a dedicated radio resource control (RRC) connection through the Type-2 (i.e., two-step random access procedure) random access response process, then during the PUSCH transmission in the two-step random access response process, .in This indicates the target power of the preamble (a higher-layer parameter configured by the base station). preambleReceivedTargetPower specified), It is the transmit power offset between the random access message A PUSCH and the random access preamble, determined by the configuration information. msgA- DeltaPreamble Specify; if not configured, the default will be used. .

[0154] For formula (2) above, if it is a normal PUSCH transmission (such as PUSCH transmission other than four-step random access and two-step random access), then ,in, It can be specified by the higher-level parameter nominal p0 (i.e., the parameter in the configuration information above). p0-NominalWithGrant If not configured, then .parameter Based on field p0-PUSCH- AlphaSetId From a set of p0 and alpha configured by the base station P0-PUSCH-AlphaSet Obtained from [the source].

[0156] in, This indicates the number of RBs in PUSCH. This indicates the scheduling bandwidth of PUSCH.

[0157] in, This represents the path loss of the active downlink bandwidth portion (BWP) estimated by the UE using a reference signal, in decibels. If the UE is not provided with a reference signal for PUSCH path loss acquisition (e.g., ...), PUSCH-PathlossReferenceRS or enableDefaultBeamPlForSRS If the UE can use the reference signal in the synchronization signal block (SS / PBCH block, SSB) to estimate the path loss, the SSB is the SSB that the UE uses to receive the master information block (MIB).

[0158] The specific calculation method is as follows: = referenceSignalPower – higher layer filtered RSRP ,in referenceSignalPower The transmission power of the reference signal, higher layer filtered RSRP This is the received power of the reference signal.

[0162] The BPRE in formula (3) can vary depending on the content sent by the PUSCH. For example, for uplink data, For channel state information (CSI), then .in It refers to the number of code blocks (also known as coded blocks, CBs, etc.) sent. It is the first The size of a code block (e.g., the size of a code block can be measured in bits). It refers to the number of resource elements (REs), such as... . Indicates the modulation order. It is a PUSCH sending opportunity PUSCH symbol The number of subcarriers (or resource elements) excluding DMRS and the phase tracking reference signal (PTRS). If the PUSCH contains uplink data, then If PUSCH only contains CSI, then , This is the power offset value corresponding to CSI. Indicates PUSCH sending opportunity The number of OFDM symbols in the data.

[0163] in, This indicates the cumulative transmit power control (TPC) power corresponding to the PUSCH power control state. Satisfy the following formula:

[0164] (4)

[0165] in, This indicates the cumulative power adjustment received by the UE between the following two time periods: PUSCH transmission opportunity. Before One OFDM symbol, PUSCH transmission opportunity Before OFDM symbols. This represents the number of OFDM symbols between the last OFDM symbol received from the uplink scheduling grant (corresponding PDCCH or DCI) (i.e., the last received time) and the first OFDM symbol before the PUSCH transmission (i.e., the earliest transmitted time). When or When reconfigured, this value can be reset to 0, i.e. .

[0166] It is understood that the explanations of the formulas or parameters shown above are merely examples. For any parts not described in detail, please refer to relevant standards or protocols, such as [8-1, TS 38.101-1], [8-2, TS38.101-2], [8-3, TS38.101-3], [11, TS 38.321], [5, TS 38.212], [4, TS 38.211], [7, TS 38.215], [12, TS38.331], [6, TS 38.214], etc., which will not be elaborated here.

[0167] Generally, information such as the time-domain or frequency-domain resources of uplink data can be determined through downlink control information (DCI). The time-domain resources of this uplink data can be within a single time slot, and can be indicated by the start OFDM symbol (i.e., the starting position of the time-domain resources) and the duration (also referred to as the duration length, etc.). Figure 3 As shown, the gray area represents time-domain resources from OFDM symbol 2 to OFDM symbol 10 (also referred to as from OFDM symbol index 2 to OFDM symbol index 10), meaning the time-domain resources comprise a total of 9 OFDM symbols. For example, the time and frequency resources scheduled within a time slot are referred to as transmission occasions (as indicated in relevant standards or protocols, a PUSCH transmission occasion does not span multiple time slots).

[0168] Generally, an uplink transport block (TB) can be encoded into multiple versions (i.e., redundant versions). A redundant version can be transmitted through a single PUSCH transmission opportunity. Simultaneously, the base station can instruct the UE to transmit multiple redundant versions on multiple different transmission opportunities.

[0169] However, how should the terminal device control power when TB is transmitted through multiple time slots? If the formula described above is simply applied to the scenario where TB is transmitted through multiple time slots, it will cause a mismatch between the uplink transmission power and the multiple time slots, which may lead to base station reception failure or affect other UEs.

[0170] In view of this, embodiments of this application provide a method and apparatus for determining transmission power. By associating the transmission power with the number of time slots or the number of OFDM conformances, the terminal device can reasonably control the transmission power according to this method, ensuring that the uplink transmission power is controlled within a reasonable range. This improves the situation of base station reception failure, or it can also reduce interference to other UEs. Meanwhile, as described above, generally a single redundant version of the uplink transport block after channel coding is transmitted through one time slot. However, the method provided in this application is applicable to transmitting a single redundant version of the uplink transport block after channel coding simultaneously through multiple time slots.

[0171] Figure 4 This is a schematic flowchart of a method for determining transmission power provided in an embodiment of this application, as shown below. Figure 4 As shown, the method includes:

[0172] 401. The terminal device determines the first transmission power based on the N time-domain resources corresponding to the first transmission block. The first transmission power is the transmission power of the first transmission block on each time-domain resource, and the size of the N time-domain resources is greater than 1 time slot, where N is a positive integer.

[0173] The aforementioned N time-domain resources being larger than one time slot can also be understood as follows: the length occupied by the N time-domain resources is greater than one time slot; the length occupied by the N time-domain resources is greater than T OFDM symbols, where T is not less than 14, or T is greater than or equal to 2 (e.g., the N time-domain resources occupy two time slots, each time slot occupies one OFDM symbol, i.e., the N time-domain resources include 2 OFDM symbols, which are distributed across different time slots); or, the N time-domain resources are distributed across at least two time slots; or, the number of time slots occupied by the N time-domain resources is greater than one time slot. These N time-domain resources can be continuous or discontinuous.

[0174] For example, the aforementioned N time-domain resources can be used to carry transport blocks (also referred to as those used for mapping transport blocks, etc.), that is, the aforementioned N time-domain resources include time-domain resources used for transmitting the first transport block. Optionally, the N time-domain resources may also include time-domain resources occupied by the corresponding demodulation reference signal (DMRS), wherein the demodulation reference signal is associated with the physical data channel corresponding to the first transport block. In other words, the PUSCH shown below in the embodiments of this application can be used to carry signals corresponding to the first transport block. The signals corresponding to the first transport block include the first transport block, or may also include reference signals such as DMRS or sounding reference signals (SRS), etc.

[0175] The following can be understood regarding N time-domain resources:

[0176] The first type involves N time-domain resources that are contiguous, and the length of these N time-domain resources is greater than one time slot.

[0177] For example, if the unit of time-domain resources is a time slot, then the N time-domain resources can be understood to include N time slots, where N is an integer greater than 1. For example, the N time-domain resources may include 2 time slots, 3 time slots, or 4 time slots, etc. In this case, the first transmission power can be understood as the transmission power of the first transmission block in each time slot.

[0178] For example, if the unit of time-domain resources is OFDM symbols, then the N time-domain resources can include K OFDM symbols. For instance, K is an integer not less than 14, such as K=14, K=18, K=20, or K=29, etc., and will not be listed here. For example, such as... Figure 5a As shown, the N time-domain resources can include 18 OFDM symbols. Since one time slot includes 14 OFDM symbols (OFDM symbol indices 0 to 13), the 18 OFDM symbols are greater than one time slot. In this case, Figure 5a The time-domain resources shown can be understood as two time-domain resources, and the first transmission power can be understood as the transmission power of the first transmission block on each time-domain resource. For example, since... Figure 5a The time-domain resource shown can also be understood as a continuous time-domain resource. Therefore, in this case, the first transmission power can also be understood as the transmission power of the first transmission block on this one time-domain resource. It is understood that the relationship between N and K is not limited in this embodiment. For example, if N time-domain resources are in units of time slots, then N is less than K; or if N time-domain resources are in units of OFDM symbols, then N equals K. It is understood that the units of time-domain resources shown here are merely examples, and as technology evolves, time-domain resources may have other units of measurement, etc., which are not limited in this embodiment.

[0179] The second type involves N time-domain resources that are discontinuous, and the length occupied by the N time-domain resources is greater than 1 time slot.

[0180] Optionally, the length occupied by N time-domain resources can be understood as: the total length of the OFDM symbols occupied by the N time-domain resources is greater than one time slot. That is, the total length of the OFDM symbols occupied by each of the N time-domain resources is greater than one time slot. For example, as... Figure 5b Although the length of each time-domain resource is no more than one time slot, Figure 5b The two time-domain resources shown occupy a total OFDM symbol length of 18 symbols, which is greater than one time slot. For example, as... Figure 5cAs shown, although the lengths of the three time-domain resources are 9 OFDM symbols, 4 OFDM symbols, and 3 OFDM symbols respectively, all less than one time slot, the total length of OFDM symbols occupied by these three time-domain resources is 16 OFDM symbols, which is greater than one time slot. In this case, the first transmission power can be understood as the transmission power of the first transmission block on each time-domain resource. For example, since... Figure 5c The diagram shows three discontinuous time-domain resources; therefore, the first transmission power can be the transmission power of each of these three time-domain resources. For example, since... Figure 5c The time-domain resources shown are distributed across two time slots. The first transmission power can also be understood as the transmission power of each time-domain resource (such as each time slot) in the two time-domain resources.

[0181] Optionally, the length occupied by N time-domain resources can be understood as: the number of time slots occupied by N time-domain resources is greater than 1 time slot. For example, such as... Figure 5d As shown, the lengths of the two time-domain resources are 5 OFDM symbols and 4 OFDM symbols respectively, and the total length of the OFDM symbols occupied by these two time-domain resources is less than one time slot. However, these two time-domain resources are distributed across two time slots, which can also be interpreted as the number of time slots occupied by these two time-domain resources being greater than one time slot.

[0182] Understandable, actually regardless of Figures 5a to 5c ,still Figure 5d This can all be understood as N time-domain resources distributed across more than one time slot. For example, from... Figures 5a to 5c It can be seen that the N time-domain resources are clearly distributed across 2 time slots, i.e., more than 1 time slot. It is understood that these N time-domain resources can be measured in units of time slots, OFDM symbols, etc., and the units for these N time-domain resources are not limited in this embodiment.

[0183] In this embodiment of the application, the first transmission power is not only related to N, but may also be related to at least one of the following:

[0184] The frequency domain resources corresponding to the first transport block, such as the number of RBs or REs used to transmit the first transport block (or, as can be understood, the number of RBs or REs for the PUSCH), etc. For example, these frequency domain resources can be used to determine the transmit power offset value. Or, these frequency domain resources can be used to determine the scheduling bandwidth of the PUSCH, etc.

[0185] The modulation order of the first transmission block (e.g.) For example, the modulation order can be used to determine the transmit power offset value (such as BPRE), etc.

[0186] The target coding rate of the first transport block, such as the MCS of the first transport block (e.g. deltaMCSFor example, the target coding rate can be used to determine the transmit power offset value (e.g., ...). )wait.

[0187] The size of the first transport block is such that the size of the code blocks it comprises. For example, the size of the first transport block can be used to determine a transmit power offset value (such as BPRE).

[0188] In other words, the first transmission power can be determined not only by N, but also by one or more of the above.

[0189] The transmission power of the first transmission block satisfies the following formula:

[0190] [dBm](5)

[0191] in, P Indicates the first transmission power. This indicates the maximum transmit power of the first transmission block. Indicates the target power of the first transmission block. A function representing the bandwidth M of the first transmission block (also known as...)

This represents the estimated path loss. This represents the offset value of the transmit power of the first transmission block. This represents the cumulative power adjustment value of the transmission power of the first transmission block.

[0193] This can be understood as the bias value of the first transmission power. For details regarding the function for N, please refer to formulas (8) and (9) shown below, which will not be elaborated here. For example, the configuration value and... The relationships between the values ​​can also be shown in Table 2 or Table 3. The N shown in Table 2 can be obtained from the configuration information. For example, if the value corresponding to N in the configuration information is n1, then the corresponding... It can be ,like It can be equal to any one of 3, 4, or 5, or...

Table 3 can represent the corresponding values ​​when N takes a certain value. For a certain value, such as or It is understood that n1 and n2 shown here are merely examples. For instance, when N time-domain resources include 14, 20, or 28 OFDM symbols (or N time-domain resources include more than or equal to 14 OFDM symbols and less than or equal to 28 OFDM symbols), the value of N can correspond to n1. Similarly, when N time-domain resources include 29, 35, or 42 OFDM symbols (or N time-domain resources include more than or equal to 29 OFDM symbols and less than or equal to 42 OFDM symbols), the value of N can correspond to n2. Exemplarily, n1 or n2 can be obtained from the corresponding information in the configuration information (e.g., when indicated by 1 bit, n1 can be equal to 0, and n2 can be equal to 1; or, when indicated by 2 bits, n1 can be equal to 00, and n2 can be equal to 01, etc.).

[0209] Understandably, the above-mentioned This can be understood as a power adjustment amount. In other words, the terminal device can determine the power adjustment amount through N, and then determine the first transmission power based on this power adjustment amount.

[0210] As you can understand, the specific method for determining the first transmission power can be found in the following text.

[0211] 402. The terminal device transmits the first transmission block on N time-domain resources using the first transmission power.

[0212] Generally, a transport block (TB) can include multiple code block groups (CBGs), and a CBG can include multiple code blocks (CBs). Therefore, transmitting the first transport block as shown in the embodiments of this application can also be understood as transmitting multiple code blocks obtained based on the first transport block. These multiple code blocks are obtained after channel coding of the first transport block. Thus, the terminal device transmitting the first transport block on N time-domain resources using a first transmit power can be understood as transmitting multiple code blocks on N time-domain resources using a first transmit power. Alternatively, transmitting the first transport block on N time-domain resources can also be understood as transmitting one or more code blocks (such as codeblocks) after channel coding of the first transport block using OFDM symbols distributed on N time-domain resources.

[0213] The N time-domain resources corresponding to the first transport block shown above can be understood as: N time-domain resources used for transmitting (or sending) the first transport block; or, the first transport block is mapped onto N time-domain resources.

[0214] It is understood that, in conjunction with the method provided in the embodiments of this application, mapping the first transport block to multiple time-domain resources (i.e., the aforementioned N time-domain resources) can be achieved in the following ways:

[0215] 1. When determining the size of the first transport block, it is based on the number of time slots to which the first transport block is mapped.

[0216] 2. When determining the time-domain resources mapped to the first transport block (i.e., determining the above N time-domain resources), the time-domain resources are located on multiple different time slots.

[0217] 3. The number of uplink OFDM symbols indicated in the uplink scheduling authorization is greater than a predefined value. For example, it may be greater than 12, or greater than 14, etc. The specific value of this predefined value is not limited in the embodiments of this application.

[0218] 4. The starting OFDM symbol position S and the number of consecutive OFDM symbols L of the time-domain resources (i.e., the N time-domain resources mentioned above) indicated in the uplink scheduling authorization satisfy the following condition in the time slot: S + L > X, where X is an integer. For example, X is greater than a predefined value. For example, X > 14, or X > 20.

[0219] It is understood that the time slots shown in the embodiments of this application may be determined based on the subcarrier spacing used during uplink transmission, or the time slots may be determined based on the subcarrier spacing on which the downlink control channel or downlink data channel for transmitting uplink scheduling authorization is based.

[0220] In this embodiment, the OFDM symbols included in the above-mentioned N time-domain resources can be collectively formed into a single transmission occasion. Alternatively, each of the N time-domain resources can constitute a single transmission occasion, thus allowing the N time-domain resources to form N transmission occasions.

[0221] It is understandable that the above explanation uses the first transport block as an example to illustrate the method of determining the transmission power. However, the first transport block can also be transmitted via PUSCH, so the method of determining the transmission power can also be illustrated using PUSCH as an example. Therefore, step 401 can be replaced with: determining the first transmission power based on the N time-domain resources corresponding to the PUSCH, where the first transmission power is the transmission power on each time-domain resource, the size of the N time-domain resources is greater than one time slot, and N is a positive integer. Step 402 can also be replaced with: transmitting the PUSCH on the N time-domain resources using the first transmission power. This PUSCH can be used to carry the first transport block.

[0222] In this embodiment, by associating the first transmission power with N time-domain resources corresponding to the transport block, the terminal device can determine the first transmission power based on these N time-domain resources, thereby ensuring that the first transmission power is controlled within a reasonable range and that the terminal device can reasonably control the transmission power. This improves the situation where the network device fails to receive the transport block, or it can also reduce interference with other terminal devices.

[0223] The following details the method for determining the first transmission power.

[0224] In some embodiments of this application, It can be related to N (or determined by N), and the first transmission power satisfies the following formula:

[0225]

[0226] In other words, in formula (6) The following formula can be satisfied:

[0227] (11)

[0228] It is understood that the explanation of each parameter in formula (10) and formula (11) can be referred to the various embodiments shown above, such as the explanation of formula (6) above, or the explanation of formula (1) above, or the description of each parameter in relevant standards or protocols, etc., which will not be detailed here.

[0229] For example, in formula (10) This can be explained as in formula (3) above. When high-level parameters (such as deltaMCS When enabled, .otherwise, Understandable, for When the change of formula (10) is shown in formula (13) below, please refer to the following formula (13).

It is a PUSCH sending opportunity PUSCH symbol The number of subcarriers (or resource elements) excluding the DMRS and phase tracking reference signal (PTRS). For example, It can also vary depending on the content sent in the PUSCH. For example, if the PUSCH contains uplink data, then... If PUSCH only contains CSI, then , This refers to the power offset value corresponding to CSI, which will not be described in detail here. Indicates PUSCH sending opportunity The number of OFDM symbols in the data.

This can be a fraction, corresponding to scheduling at the resource element (or subcarrier) level. For example, .For example, .For example, .For example, Understandable. It can be a fraction not only less than 1, but also a fraction greater than 1. For example, .

[0232] In this embodiment of the application, since PUSCH is sent through N time-domain resources, at the same time... The scheduling bandwidth of PUSCH can be represented by the above formula (11), which can be used to represent the scheduling bandwidth of PUSCH on each time domain resource. Thus, even if PUSCH is transmitted through a time domain resource with more than one time slot, the terminal device can determine the first transmission power based on the time domain resource, so that the terminal device can reasonably control the transmission power.

[0233] In other embodiments of this application, the first transmission power satisfies the following formula:

[0252] For formula (17), since This can represent the opportunity to send a PUSCH. exist The number of OFDM symbols in each time slot of each time domain resource. Therefore, for N time domain resources, although the transmission power on each time domain resource is the first transmission power, that is, the first transmission power can be determined by formula (17), the transmission power on each time domain resource may be the same or different. This application embodiment does not limit this.

For example, this can be achieved by adding a field to the higher-level parameters. p0-NominalTBOverMultiSlot This indicates the nominal p0. In other words, the base station can send configuration information to the UE, and this configuration information may include this field. p0-NominalTBOverMultiSlot This field can be used to indicate the nominal p0, which can be used to determine... .

At the same time, N in Table 4 or Table 5 can take more values, etc., and this application embodiment does not limit this either.

[0266] In one possible implementation, This can be specified by a higher-level parameter. For example, this higher-level parameter may include fields. p0-PUSCH-AlphaSetId Fields p0-PUSCH-AlphaSet or field P0-PUSCH- AlphaSetMultiSlot One or more of them. For example, p0-PUSCH-AlphaSet This can indicate the transmission method of the first transport block. For example, the UE can determine this based on the field. p0-PUSCH-AlphaSetId Determine this field p0-PUSCH-AlphaSet Whether it is used to map the first transport block to N time-domain resources (such as N time slots, or K OFDM symbols, etc.), such as when p0-PUSCH- AlphaSetIdWhen the value is less than or equal to a predefined value (for example, a predefined value of 30; or, for example, a predefined value of 20), p0-PUSCH- AlphaSet This can be used for transmission methods where the first transport block is mapped to a single time slot (i.e., consecutive time-domain resources are less than or equal to one time slot); when p0-PUSCH-AlphaSetId When it is greater than the predefined value, p0-PUSCH-AlphaSet It can be used for a transmission method that maps the first transport block to N time-domain resources.

[0267] For example, the signaling format for the field P0-PUSCH-AlphaSetMultiSlot can be as follows:

[0269] In this context, P0-PUSCH-AlphaSetMultiSlot represents the possible set of p0 and alpha values ​​corresponding to the PUSCH, and p0-PUSCH-AlphaSetId represents the index of the set of p0 and alpha values ​​corresponding to the PUSCH. N represents the number of time slots mapped to a transport block in the PUSCH. sl1 indicates that a transport block is mapped to 1 time slot, sl2 indicates that a transport block is mapped to 2 time slots (which can be understood as the transport block being distributed across 2 time slots), sl4 indicates that a transport block is mapped to 4 time slots (which can be understood as the transport block being distributed across 4 time slots), and so on, with sl20 indicating that a transport block is mapped to 20 time slots. p0 represents the p0 value corresponding to the PUSCH, and alpha represents the alpha value corresponding to the PUSCH.

[0277] In some other embodiments of this application, the cumulative transmit power control power may be related to N, and the first transmit power satisfies the following formula:

[0278]

[0279] For example, the cumulative power adjustment value satisfies the following formula:

[0280] (20)

[0281] in, This indicates the cumulative power adjustment received by the UE between the following two time periods: PUSCH transmission opportunity. Before One OFDM symbol, PUSCH transmission opportunity Before OFDM symbols. This represents the number of OFDM symbols between the last OFDM symbol received from the uplink scheduling grant (corresponding PDCCH or DCI) (i.e., the last reception time) and the first OFDM symbol before the PUSCH transmission (i.e., the earliest transmission time). When or When reconfigured, this value is reset to 0, that is... .

[0282] Optional, such as PUSCH sending opportunity The number of time slots mapped in the first transport block is PUSCH sending opportunity The number of time slots mapped in the first transport block is The first transmission power can be compared with and Relevant. For example, when Not equal to hour, For example, when... and Time difference Exceeding the threshold At times (for example, ), ,or ,or For example, Understandably, what is shown here...

[0289] It is understood that in the various embodiments shown above, if a part of one embodiment is not described in detail, other embodiments can be referred to. The various embodiments shown above can also be combined with each other. For example, formula (10) shows that the bandwidth of the first transmission block is related to N, and formula (15) shows that the transmission power offset value is related to N. In the embodiments of this application, formula (10) and formula (15) can also be combined to determine the first transmission power. That is to say, in the first transmission power, the bandwidth of the first transmission block is not only related to N, but the transmission power offset value can also be related to N. For example, formula (18) shows that Since it is related to N, the first transmission power can also be determined by combining formula (10) and formula (18). Alternatively, the first transmission power can also be determined by combining formula (15) and formula (18), or by combining formula (10), formula (15) and formula (18), etc., which will not be detailed here.

[0290] To understand in more detail the method for determining transmission power provided in the embodiments of this application, Figure 6a This is a schematic flowchart of another method for determining transmission power provided in an embodiment of this application, as shown below. Figure 6a As shown, the method includes:

[0291] 601. The base station sends configuration information to the UE, and the UE receives the configuration information accordingly.

[0292] For example, this configuration information includes power configuration information, which can be used in scenarios where a first transport block is mapped to multiple time slots. For example, this can be achieved through fields in the RRC. p0-NominalTBOverMultiSlot Indication. For example, when the UE determines that the first transport block is mapped to multiple time slots, the UE can use this field. p0- NominalTBOverMultiSlot The indicated nominal p0 value determines the first transmission power. Further explanation of the fields included in the configuration information can be found in the above embodiments, and will not be detailed here.

[0293] 602. The base station sends a downlink reference signal to the UE, which is used to determine the path loss corresponding to the PUSCH. The corresponding UE receives the downlink reference signal.

[0294] 603. The base station sends an uplink scheduling grant (UL grant) to the UE, and the UE receives the uplink scheduling grant. The uplink scheduling grant can be indicated by any one or more of the following: physical downlink control channel (PDCCH), medium access control-control element (MAC-CE), or radio resource control (RRC) signaling.

[0295] For example, the UE can determine the parameters by which the first transport block is mapped to multiple time slots based on the uplink scheduling grant. For instance, the UE can determine the number of time slots N to which the first transport block is mapped, the starting OFDM symbol S, and the number of consecutively mapped OFDM symbols L. For example, the parameters configured in the uplink scheduling grant can be included in the configuration information described above.

[0296] 604. The UE determines the first transmission power based on the uplink scheduling authorization and / or power configuration information.

[0297] For example, the UE can determine the first transmission power based on one or more of N, S, L, or S+L. The specific method for determining the first transmission power is detailed below, but will not be elaborated here.

[0298] 605. The UE transmits the first transmission block using the first transmission power.

[0299] For example, the processing of transport blocks can be as follows: Figure 6bAs shown, after the UE obtains the first transport block, it can perform modulation, layer mapping, or precoding on the first transport block to obtain the modulation symbol corresponding to the first transport block. Simultaneously, the modulation symbol corresponding to the first transport block is mapped onto N time-domain resources, and the modulation symbol corresponding to the first transport block is transmitted through these N time-domain resources.

[0300] In conjunction with the methods described above, embodiments of this application also provide a method for processing transport blocks, such as... Figure 6c As shown, the method includes:

[0301] 611. The UE receives the first transport block from the higher layer (such as the higher layer of the UE).

[0302] For example, the first transport block can be a medium access control (MAC) protocol data unit (PDU). The size of the first transport block (TBS) is determined based on at least one of the following: time-domain resources indicated in the DCI (such as the N time-domain resources provided in the embodiments of this application), frequency-domain resources, MCS, and the number of transport layers (and / or ports) (e.g., which can be denoted as...). The MCS can be index information, such as indicating the modulation order. Target coding bit rate Information such as spectral efficiency.

[0303] For example, the UE can also determine the size of the first transport block through steps a to e shown below, which will be explained in detail below:

[0304] Step a: UE determines the unquantized intermediate variables. . .

[0305] in, The mapping layer number of the first transport block. The number of resource elements (REs) mapped in the first transport block. For the target encoding bitrate, For modulation order. Optional, regarding... The description can be found in the above embodiments; or, the Alternatively, it can be determined according to the following implementation method.

[0306] For example, when the number of OFDM symbols (or OFDM symbol locations) in each time slot (i.e., N time-domain resources are the same, and the number and location of OFDM symbols included in each time slot corresponding to these N time-domain resources are also the same) and the number of frequency-domain resource blocks (or resource block locations) are the same, the determination can be made as follows: .Should This can be understood as the number of REs allocated to the PUSCH within the PRB (index denoted as k). For example, when the configuration in each time slot (such as the number and location of OFDM symbols occupied in each time slot) is exactly the same, in, The value is a fixed value and can represent the number of subcarriers contained in a PRB in the frequency domain, for example... This represents the number of OFDM symbols scheduled for the k-th RB (which can be granular at the RB or RBG level) in a time slot. This represents the amount of overhead for the k-th RB (or RBG) in a time slot, for example, the amount of overhead used for CSI-RS transmission. For another example, when the overhead of each resource block in each time slot is exactly the same as the DMRS configuration, , The value is a fixed value, for example ; This indicates the number of OFDM symbols scheduled for each RB (or RBG) in a time slot; This indicates the amount of overhead per RB (or RBG) in a time slot, for example, the amount of overhead used for CSI-RS transmission.

[0307] For example, when the number of OFDM symbols (or OFDM symbol locations) and the number of frequency domain resource blocks (or resource block locations) in each time slot are not exactly the same, they can be determined as follows: .Should This can be understood as the number of REs allocated to PUSCH within the PRB (index denoted as k). For example, if the configuration in each time slot is exactly the same, then , The value is a fixed value, for example ; This represents the number of OFDM symbols scheduled for the k-th RB (or RBG) in time slot s; This represents the amount of overhead for the k-th RB (or RBG) in time slot s, for example, the amount of overhead used for CSI-RS transmission. For another example, if the overhead of each resource block in each time slot is exactly the same as the DMRS configuration, then... , The value is a fixed value, for example ; This indicates the number of OFDM symbols scheduled for each RB (or RBG) in time slot s; This indicates the amount of overhead for each RB (or RBG) in time slot s, for example, the amount of overhead used for CSI-RS transmission.

[0308] Based on the above method, the number of resource elements allocated in the entire PUSCH is... , or for .

[0309] Step b, UE based on intermediate variables Determine intermediate variables after quantization .

[0310] It should be pointed out that, in The method by which the UE determines the first TBS can vary depending on the value of .

[0311] In one possible implementation, In this case, the UE determines the value of the first TBS according to steps c and d (denoted as Case I). In this case, the UE determines the value of the first TBS according to steps e and f (denoted as Case II). Case I and Case II are explained in detail below:

[0312] Case I

[0313] In Case I, the UE determines the value of the first TBS according to steps c and d.

[0314] Step c, UE determination .in, .

[0315] Step d: The UE can query tables in Table 10 for values ​​not greater than... The maximum value is taken as the value of the first TBS. For example, the value determined according to the formula above... If the value is 1200, then according to Table 10, the maximum value not greater than 1200 is 1192, so the first TBS is 1192 bits. It should be understood that Table 10 is only an example, and the correspondence between the index and TBS is not limited in the embodiments of this application.

[0318] Case II

[0319] Step e, UE determination .in, .

[0320] Step f: The UE determines the target coding bit rate. ,as well as Determine the value of the first TBS. It can be understood that TBS1, as shown below, represents the size of the first transport block.

[0321] In one possible implementation, hour, .in, .

[0322] exist and hour, .in, .

[0323] exist and hour, .

[0324] It is understandable that for any part of the above parameter descriptions that is not described in detail in one implementation method, you can refer to another implementation method.

[0325] 612. The UE adds cyclic redundancy check information to the first transport block and obtains the second transport block.

[0326] For example, the method for adding CRC information to the UE can refer to relevant standards or protocols, such as TS 38.212, etc., which will not be described in detail here.

[0327] 613. The UE performs block processing on the second transmission block to obtain one or more code blocks, such as code block 1.

[0328] For example, the UE can divide the second transport block into blocks through the physical layer to obtain C code blocks, where C is a positive integer.

[0329] It is understandable that whether the UE adds CRC information to these multiple code blocks can be determined based on the value of C. For example, when C=1, since the code block is equivalent to the original transport block, the UE does not need to add CRC information to the code blocks after the second transport block is segmented. Alternatively, when C is greater than 1, the UE can add CRC information to these C code blocks.

[0330] 614. The UE performs channel coding on code block 1 to generate code block 2.

[0331] 615. The UE performs rate matching on code block 2 (or the UE can scramble code block 2) to generate code block 3.

[0332] In one possible implementation, the size of the code block E (i.e., as mentioned above) , It satisfies the following formula:

[0333] (twenty one)

[0334] In another possible implementation, the size E of the code block satisfies the following formula:

[0335] (twenty two)

[0336] It is understood that in this application, To round up, you can also use... This indicates that, in other implementations, the value of E can also be determined by rounding, for example, round( The embodiments in this application are not limited to these.

[0337] For example, the total number of bits G1 after encoding the first transport block can satisfy the following formula:

[0338] (twenty three)

[0339] It is understandable that the parameters in formulas (21) to (23) are explained as follows: E represents the size of the code block (i.e., as shown above). ), Indicates the mapping layer number of the first transport block. G1 represents the modulation order of the first transport block, and G1 is the total number of bits after encoding the first transport block. This indicates the number of transport layers (or ports) for the first transport block, and C represents the number of code blocks corresponding to the first transport block. This indicates the number of REs mapped in the first transport block.

[0340] 616. The UE modulates and maps the code block 3.

[0341] 617. The UE maps the modulated and layer-mapped code block 3 onto time-frequency resources (such as the time-domain resources in the time-frequency resources, which can be the N time-domain resources shown in the embodiments of this application).

[0342] 618. The UE sends a PUSCH to the base station. The PUSCH can be carried on N time-domain resources. At the same time, the PUSCH can include code block 3.

[0343] It is understood that the embodiments of this application do not limit the number of code blocks included in code block 1, code block 2, and code block 3. It is also understood that for channel coding methods, rate matching methods, modulation methods, etc., relevant standards or protocols can be referenced, and the embodiments of this application do not limit them.

[0344] In this embodiment, the UE can determine the first transmission power based on the time domain resource, so that the terminal device can reasonably control the transmission power.

[0345] It is understood that in the various embodiments shown above, where one embodiment is not described in detail, other embodiments may be referenced.
