Description

Channel transmission method, device, equipment and storage medium Technical Field

[0001] The present application relates to the field of communications, and in particular to a channel transmission method, apparatus, device, and storage medium. Background Art

[0002] Integrated communication and perception is a technology with great application prospects.

[0063] First, the communication technology involved in the embodiments of this application is introduced:

[0064] 1. Communication and perception integrated technology

[0065] Wireless communication and sensing are two key applications of modern radio frequency technology. Sensing uses radio waves to detect parameters of the physical environment, enabling environmental perception such as target location, motion recognition, and imaging. Traditionally, sensing and wireless communication have existed independently, and this separation wastes wireless spectrum and hardware resources.

[0066] As wireless communication spectrum moves toward millimeter waves, terahertz, and visible light, the overlap between wireless and sensing spectrums is increasing. Integrated communication and sensing technologies are being used to merge wireless communication and sensing functions, enabling the same signal to simultaneously perform both communication and sensing, thereby improving spectrum utilization. Furthermore, wireless communication and wireless sensing are increasingly similar in terms of system design, signal processing, and data processing. Using the same device to implement both communication and sensing functions also helps reduce equipment costs.

[0067] Communication-perception integration technology, also known as synaesthesia integration, can be broadly categorized into two types: communication-assisted perception and perception-assisted communication. Communication-assisted perception refers to the transmission and aggregation of perception information via wireless communications, which can expand the breadth and depth of perception services and improve their timeliness. Fusion of communication and perception technology can provide efficient perception services such as high-precision positioning, high-resolution imaging, and virtual environment reconstruction. This can effectively build digital twin environments, enabling digital re-presentation and deep processing across numerous industries.

[0068] 2. Time-frequency resources of physical channels

[0069] Generally speaking, network equipment allocates the time and frequency resources required for transmission on physical channels to terminal devices based on factors such as the transport block size (TBS) carried by the physical channel, channel conditions, and reliability requirements. Examples of physical channels include the physical downlink shared channel (PDSCH) and the physical uplink shared channel (PUSCH).

[0070] When channel conditions are poor and reliability requirements are high, network devices typically select a lower Modulation and Coding Scheme (MCS) level. A lower MCS level means a lower code rate, which results in more time and frequency resources being used by the physical channel. To accommodate various communication scenarios, multiple MCS mapping tables are available to meet the communication needs of various scenarios. For more information, please refer to 3rd Generation Partnership Project (3GPP) TS 38214.

[0071] For time-domain resource allocation, network devices can schedule time-domain resources with granularity down to a single symbol or multiple symbols within a time slot. For example, the MCS mapping table can indicate the number of symbols (L) and the starting symbol (S) occupied by the physical channel to adapt time-frequency resource allocation to different service requirements.

[0072] 3. Steps for determining TBS

[0073] Taking the PDSCH as an example, determining the TBS in the PDSCH can be achieved through the following three steps:

[0074] 1) Determine the number of resource elements (REs) N for PDSCH RE ,include:

[0075] i. Determine the number of REs within a physical resource block (PRB). The calculation formula is:

[0076] in, Indicates the number of subcarriers in a resource block (RB); The number of symbols occupied by PDSCH in a time slot; The number of REs occupied by the demodulation reference signal (DMRS) in a PRB; The number of overhead REs configured within a PRB. In some embodiments, the number of overhead REs includes the number of REs occupied by control information of at least one of the synchronization channel, physical broadcast channel (PBCH), physical downlink control channel (PDCCH), and physical uplink control channel (PUCCH). In some embodiments, the number of overhead REs includes, but is not limited to, the number of REs occupied by at least one of reference resources, such as the Channel State Information Reference Signal (CSI-RS) and the Control Resource Set (CORESET).

[0077] ii. Determine the number of REs in PDSCH. The calculation formula is: N RE =min(156,N′ RE )×n PRB .

[0078] Among them, n PRB It is the number of PRBs allocated by the network device to the terminal device.

[0079] 2) Calculate the amount of intermediate information N carried by PDSCH info , the calculation formula is: N info =N RE ×R×Q m ×υ.

[0080] Among them, N RE is the calculated number of REs in PDSCH, R is the coding rate of PDSCH, Q mIt is the modulation order of the data on PDSCH, and υ represents the number of transmission layers of PDSCH.

[0081] 3) Based on the intermediate information N info Determine TBS:

[0082] i. If N info ≤3824, TBS was determined by quantitative table lookup;

[0083] ii. If N info >3824, TBS was determined by quantitative calculation.

[0084] However, the coding rate supported by a communication system has a lower limit, which means that there is a minimum value for R. Even if the lowest coding rate supported by the communication system (such as 30 / 1024) is used to transmit a small amount of data, the time and frequency resources occupied by the physical channel are not large enough to meet the perception requirements.

[0085] Taking TBS = 48 bits as an example, if R = 30 / 1024, and if the PDSCH time domain resource includes at least 2 symbols, then when using dual-port transmission, the PDSCH frequency domain resource needs to include 51 RBs. If the subcarrier spacing is 15 kHz, the bandwidth occupied by PDSCH is approximately 9M.

[0086] Taking TBS = 48 bits as an example, if R = 30 / 1024, and if the PUSCH time domain resource includes at least one symbol, then when using single-port transmission, the PUSCH frequency domain resource needs to include 90 RBs. If the subcarrier spacing is 15 kHz, the bandwidth occupied by PUSCH is approximately 12 Mbps.

[0087] When the bandwidth is about 9M or 12M, the perception resolution is about 15m, which cannot meet the accuracy requirements in most perception scenarios.

[0088] 4. Perceived needs

[0089] Perception accuracy is usually affected by the signal transmission bandwidth and transmission time. For example, the larger the signal transmission bandwidth, the higher the perception ranging accuracy, while the longer the signal transmission time, the higher the perception speed measurement accuracy.

[0090] When using communication signals for perception, the time domain resources allocated to communication signals need to consider two requirements simultaneously:

[0091] 1. Communication requirements, including data volume, transmission reliability, transmission latency, etc.

[0092] 2. Perception requirements: Different perception services have different requirements for signal transmission bandwidth and transmission time.

[0093] If, in order to meet perception needs, network equipment is scheduled to use more time-frequency resources (i.e., large bandwidth or multiple symbols) for transmission, the following problems will arise: when the amount of data transmitted is small, the sender generates a larger TB for transmission by filling in redundant information, resulting in reduced system transmission efficiency, wasted power consumption, and increased transmission delay.

[0094] Therefore, if the above communication technology is used for wireless communication and perception, it is difficult to meet the perception needs when meeting the communication needs, and it is difficult to meet the communication needs when meeting the perception needs, and it is impossible to achieve true synaesthesia integration technology.

[0095] Based on the above problems, the present application provides a channel transmission method that supports the balance between wireless communication quality and perception needs.

[0281] In some embodiments, the terminal device measures a first signal carried by the channel to obtain a first perception result.

[0282] It should be understood that when the first signal and / or transmission block is sent by the network device to the terminal device, the terminal device obtains the first perception result based on the first signal carried by the channel. In other words, when the terminal device belongs to the first node as shown in Figure 2 or Figure 3, the terminal device performs step 650a.

[0283] Step 650b: Send a first signal and / or a transmission block on the channel, where the first signal is used to obtain a first perception result.

[0290] In summary, the method provided in this embodiment satisfies the perception requirement through the first signal carried by the channel. At the same time, considering that if the channel occupies more time-frequency resources to meet the perception requirement, the TBS of the transport block carried by the channel will also increase accordingly, a solution is designed to ensure wireless communication quality by determining the TBS based on the first parameter. Compared with filling a large number of redundant bits in the transport block with an increased TBS, the method provided in this embodiment uses the first parameter to effectively adjust the transmission parameters of the channel, such as reducing the coding rate and the amount of intermediate information. This ensures that the transport block with an increased TBS carries more valid bits rather than a large number of redundant bits, reducing the transmission of redundant bits in the channel, improving the reliability, robustness, and efficiency of channel transmission, and achieving a balance between perception and communication requirements. Furthermore, it supports terminal devices reporting capability information to assist network devices in configuring the first parameter, so that the transport block / first signal carried by the channel is more consistent with the receiving capabilities of the terminal device, thereby improving the communication efficiency and transmission quality of the communication system.

[0398] In some embodiments, the time-frequency resources of a third channel among the n channels are periodically distributed in the time domain according to a period P. Exemplarily, the n channels are periodically distributed in the time domain with a period of K time domain units, and / or the n channels are periodically distributed in the frequency domain with a period of K frequency domain units.

[0399] In some embodiments, the distribution of time-frequency resources of a third channel among the n channels is associated with a period P. Exemplarily, the period P indicates that K time domain units are used as a period, and the time domain resources occupied by a certain channel among the n channels may be before K time domain units or after K time domain units. It can also be understood that the time domain resources occupied by different channels are not periodically distributed in the time domain with K time domain units as a period, but the time domain resources occupied by different channels can be determined based on the period P. For example, the time domain starting position of a certain channel is several time domain units before the period P, or several time domain units after the period P. Exemplarily, the period P indicates that K frequency domain units are used as a period, and the frequency domain resources occupied by a certain channel among the n channels may be before K frequency domain units or after K frequency domain units. It can also be understood that the frequency domain resources occupied by different channels are not periodically distributed in the frequency domain with K frequency domain units as a period, but the frequency domain resources occupied by different channels can be determined based on the period P. For example, the frequency domain starting position of a certain channel is several frequency domain units before the period P, or several frequency domain units after the period P.

[0439] In some embodiments, the n channels include at least two fourth channels, and the at least two fourth channels repeatedly transmit the first transport block. The first transport blocks in different fourth channels are assigned different RV numbers. This design allows the n channels to carry the second signal to meet perception requirements while also achieving retransmission gain through repeated transmission, thereby improving the transmission quality of the first transport block and ensuring transmission efficiency.

[0440] The RV number may also be implemented as an RV ID or an RV index.

[0441] In some embodiments, RV numbers corresponding to the first transport blocks in at least two fourth channels are arranged in a first order.

[0454] In summary, the method provided in this embodiment, since n channels occupy more time-frequency resources, the second signal carried by n channels can meet the perception requirements, and the constraint conditions effectively improve the transmission efficiency of n channels. The method provided in this embodiment avoids the waste caused by n channels occupying too many transmission resources, and also avoids the reduction of perception accuracy and communication quality caused by n channels occupying unreasonable transmission resources, thereby achieving a balance between perception requirements and communication requirements. In addition, the RV number and / or HARQ ID of the transmission block carried by n channels can be flexibly adjusted according to different orders, making full use of the time-frequency resources of n channels, so that the transmission of the transmission block can obtain retransmission gain, encoding and decoding gain, and coverage gain. The method provided in this embodiment not only saves the control overhead of n channels through the constraint conditions, but also improves the reliability and perception accuracy of n channel transmission.

[0455] Considering that the steps executed by the terminal device and the network device are not exactly the same, the channel transmission method shown in Figure 8 or Figure 9 or Figure 10 or Figure 11 is introduced from the perspective of the terminal device and the perspective of the network device respectively.

[0456] In some embodiments, step 810 or step 910 can be implemented as step 1220a, and step 1010 or step 1110 can be implemented as step 1220b. In addition to step 1220a or step 1220b, the channel transmission method may also include step 1210. As shown in Figure 12, Figure 12 shows a flow chart of the channel transmission method provided by some exemplary embodiments of the present application. Taking the method as performed by a terminal device as an example, a schematic description is given. Among them, the terminal device is implemented as a first node as shown in Figure 8 or Figure 9, or the terminal device is implemented as a second node as shown in Figure 10 or Figure 11. The method includes at least some of the following steps:

[0457] Step 1210: Receive second information, where the second information is used to indicate a second parameter;

[0458] In some embodiments, the second parameter includes at least one of the following:

[0459] Time domain resources of at least some of the n channels;

[0461] The time domain interval between the time domain resources of at least two channels;

[0462] The frequency domain spacing between the frequency domain resources of at least two channels;

[0463] Maximum number of HARQ processes for n channels;

[0464] HARQ IDs of at least some of the n channels;

[0465] RV numbers of at least some of the n channels;

[0466] First order;

[0467] · Second order.

[0468] In some embodiments, the second parameter includes the time slots corresponding to the n channels. Alternatively, the second parameter indicates the time slot corresponding to channel A among the n channels and indicates the time slot intervals between the other channels and channel A. The other channels refer to the channels other than channel A among the n channels. The time slot can be replaced with other time domain units. The time slot is used as an example here only and is not intended to be limiting.

[0469] In some embodiments, the second parameter includes the PRBs corresponding to the n channels. Alternatively, the second parameter indicates the PRB corresponding to channel A among the n channels and indicates the frequency domain spacing between the other channels and channel A. The other channels refer to the channels other than channel A among the n channels. The PRB can be replaced by other frequency domain units, such as at least one of a carrier, a BWP, a subband, a subchannel, a subcarrier, or a unit based on other frequency domain units. PRB is used as an example only and is not intended to be limiting.

[0470] In some embodiments, the second information is DCI.

[0471] In some embodiments, the second information is the same as the first information, or the second information is different from the first information.

[0472] In some embodiments, the second parameters corresponding to different channels in the n channels are the same, and / or the second parameters corresponding to different channels in the n channels are different. In some embodiments, the second parameters corresponding to different channels in the n channels can be configured uniformly or individually.

[0473] In some embodiments, the n channels correspond to the same time slot. Alternatively, the time domain resources corresponding to the n channels are located in the same time slot set, which includes one or more time slots. Alternatively, the n channels correspond to different time slots, and the time slot interval between each time slot corresponding to the n channels is less than a first threshold. Alternatively, some of the n channels correspond to the same time slot, while another portion of the n channels correspond to different time slots, and the time slot interval between each time slot corresponding to the n channels is less than the first threshold. The time slot can be replaced with other time domain units, and the time slot is used as an example here only and is not intended to be limiting.

[0474] It can be understood that by limiting the time domain resources of n channels, the first node can complete the reception of n channels in a shorter time, thereby ensuring the effectiveness of the second signal carried by the n channels for obtaining the second perception result, so that the second perception result has higher perception precision and accuracy.

[0475] In some embodiments, the time domain resource corresponding to a channel includes at least one time domain unit, and the at least one time domain unit is continuous or discontinuous. Wherein, a channel is one channel among n channels.

[0484] In some embodiments, the terminal device measures the second signal carried by n channels to obtain a second perception result.

[0485] It should be understood that when the second signal and / or transmission block is sent by the network device to the terminal device, the terminal device obtains the second perception result based on the second signal carried by the n channels. That is, when the terminal device belongs to the first node shown in Figure 8 or Figure 9, the terminal device performs step 1220a.

[0486] For details about the constraints, please refer to step 910 and will not be described in detail here.

[0487] Step 1220b: Send a second signal on n channels that meet the constraint condition, where the second signal is used to obtain a second perception result.

[0492] In some embodiments, the terminal device sends the second signal on n channels; or, the terminal device sends a transmission block on n channels, the transmission block including the second signal; or, the terminal device sends the second signal and the transmission block on n channels.

[0493] It should be understood that when the second signal and / or transmission block is sent by the terminal device to the network device, the network device obtains the second perception result based on the second signal carried by the n channels. That is, when the terminal device belongs to the second node shown in Figure 10 or Figure 11, the terminal device performs step 1220b.

[0494] In some embodiments, the RBs occupied by the second signal are continuous or discontinuous, and the RBs occupied by the second signal correspond to one or more carriers. This can also be understood as the second signal occupying RBs in one or more carriers, the second signal occupying the same or different numbers of RBs in different carriers, and the RBs being adjacent or spaced apart.

[0497] For details about the constraints, please refer to step 910 and will not be described in detail here.

[0498] In some embodiments, the n channels satisfy at least one of the following conditions:

[0499] Among the n channels, there are channels with the same modulation order;

[0500] There are channels with different modulation orders among the n channels;

[0501] Among the n channels, there are channels with the same coding rate;

[0502] Among the n channels, there are channels with different coding rates.

[0504] n transport blocks are mapped one-to-one with n channels from low to high in the frequency domain;

[0505] n transport blocks are mapped one-to-one with n channels from front to back in the time domain.

[0506] In some embodiments, the n channels include channel A, channel B, channel C, and channel D. Channel A, channel B, channel C, and channel D are arranged from low to high or from high to low in the frequency domain.

[0507] In some embodiments, the n channels include channel A, channel B, channel C, and channel D. Channel A, channel B, channel C, and channel D are arranged from front to back or from back to front in the time domain.

[0508] In some embodiments, the n channels include at least two fourth channels, the at least two fourth channels repeatedly transmit the first transport block, and the RV numbers corresponding to the first transport blocks carried by the at least two fourth channels are arranged in a first order.

[0509] In some embodiments, the n channels include at least two fourth channels, the at least two fourth channels repeatedly transmit the first transport block, and the first transport blocks in different fourth channels correspond to different RV numbers.

[0510] The RV number may also be implemented as an RV ID or an RV index.

[0511] In some embodiments, RV numbers corresponding to the first transport blocks in at least two fourth channels are arranged in a first order.

[0512] In some embodiments, the first order is agreed upon by a communication protocol or determined based on DCI.

[0513] In some embodiments, the n channels include at least two fifth channels, the at least two fifth channels respectively transmit different transport blocks, and the transport blocks in different fifth channels correspond to different HARQ IDs.

[0514] The HARQ ID may also be implemented as a HARQ number or a HARQ index.

[0515] In some embodiments, the HARQ IDs corresponding to the transport blocks in at least two fifth channels are arranged in a second order.

[0516] In some embodiments, the second order is agreed upon by a communication protocol or determined based on DCI.

[0517] It can also be understood that each channel in the fourth channel is distinguished by a different RV number, and each channel in the fifth channel is distinguished by a different HARQ ID.

[0518] First, let me introduce the fourth channel:

[0519] In some embodiments, each fourth channel repeatedly transmits the same first transport block, and the same first transport block undergoes at least one of the following processes: adding a cyclic redundancy check (CRC), channel coding, rate matching, etc., to generate different RVs, and the different RVs are distinguished by different RV numbers, so that each fourth channel corresponds to a different RV number.

[0520] With this design, the fourth channel is transmitted within n channels that meet the constraints through different RVs, so that the transmission block carried by the fourth channel obtains retransmission gain in a shorter time or even within one time slot, thereby improving the transmission reliability of the fourth channel and the reliability and effectiveness of the second perception result.

[0521] In some embodiments, the HARQ IDs of the fourth channels are the same, and the RV numbers are arranged in a first order. In some embodiments, the first order is a cycle of 0, 2, 3, and 1.

It is understood that the first order may also be an order other than the cycle of 0, 2, 3, and 1, such as a cycle of 3, 1, 0, and 2. The cycle of 0, 2, 3, and 1 is used as an example here and is not intended to be limiting.

[0522] Next, we introduce the fifth channel:

[0523] In some embodiments, each fifth channel transmits a different transport block, and different transport blocks are distinguished by different HARQ IDs, so that each fifth channel corresponds to a different HARQ ID.

[0524] Such a design transmits the fifth channel within n channels that meet the constraints through different HARQ IDs, so that the transmission block carried by the fifth channel obtains retransmission gain in a shorter time or even within one time slot, thereby improving the transmission reliability of the fifth channel and improving the reliability and effectiveness of the second perception result.

[0525] In some embodiments, the RV numbers of the respective fifth channels are the same, and the HARQ IDs are arranged in a second order. In some embodiments, the second order is a cycle from 0 to (y-1), where y = the maximum number of HARQ processes. In some embodiments, y = 4. If the n channels include 4 fifth channels, the HARQ IDs of the transport blocks carried by these 4 fifth channels are 0, 1, 2, and 3, respectively; if the n channels include 6 fifth channels, the HARQ IDs of the transport blocks carried by these 6 fifth channels are 0, 1, 2, 3, 0, and 1, respectively; if the n channels include 9 fifth channels, the HARQ IDs of the transport blocks carried by these 9 fifth channels are 0, 1, 2, 3, 0, 1, 2, 3, and 0, respectively; and so on. In some embodiments, y=2, if the n channels include 4 fifth channels, the HARQ IDs of the transport blocks carried by these 4 fifth channels are 0, 1, 0, 1, respectively; if the n channels include 6 fifth channels, the HARQ IDs of the transport blocks carried by these 6 fifth channels are 0, 1, 0, 1, 0, 1, respectively; if the n channels include 9 fifth channels, the HARQ IDs of the transport blocks carried by these 9 fifth channels are 0, 1, 0, 1, 0, 1, 0, 1, respectively; and so on.

[0526] When n channels include both the fourth and fifth channels:

[0527] In some embodiments, at least some of the n channels belong to both the fourth channel and the fifth channel. This can also be understood as at least some of the n channels having both RV numbers and HARQ IDs. Taking channel A as an example, among the n channels, there are other channels that have different RV numbers than channel A, and there are also other channels that have different HARQ IDs than channel A.

[0528] In some embodiments, the second order has a higher priority than the first order. That is, channels belonging to both the fourth channel and the fifth channel are first arranged in the second order by HARQ ID and then in the first order by RV number. In some embodiments, the y transport blocks under the first RV number are first mapped one-to-one to the y channels by HARQ ID in the second order, then the y transport blocks under the second RV number are mapped one-to-one to the y channels by HARQ ID in the second order, then the y transport blocks under the third RV number are mapped one-to-one to the y channels by HARQ ID in the second order, and so on.

[0529] In some embodiments, the second order corresponding to the HARQ ID is 0 and 1, and the first order corresponding to the RV number is 0, 2, 3, and 1. n is 4, and the n channels belong to both the fourth channel and the fifth channel, and the n channels include SH1, SH2, SH3, and SH4 (arranged from low to high in the frequency domain). Then, the channel with RV number 0 is mapped first according to the second order, and then the channel with RV number 2 is mapped according to the second order. That is, the two transport blocks with RV number 0 are first mapped one by one to SH1 and SH2 with HARQ ID in the order of 0 and 1, and then the two transport blocks with RV number 2 are mapped one by one to SH3 and SH4 with HARQ ID in the order of 0 and 1. Then, the HARQ ID of SH1 is 0 and the RV number is 0; the HARQ ID of SH2 is 1 and the RV number is 0; the HARQ ID of SH3 is 0 and the RV number is 2; and the HARQ ID of SH3 is 1 and the RV number is 2.

[0530] In some embodiments, if the time-frequency resources corresponding to a certain channel are unavailable, the unavailable time-frequency resources may be skipped for resource mapping, or no transmission may be performed on the channel, based on the agreement of the communication protocol. The unavailability of time-frequency resources includes, but is not limited to, at least one of the following: the PRB corresponding to a certain channel overlaps with the PRB used to transmit the synchronization signal block (SS / PBCH, SSB), the transmission direction of a certain channel conflicts with that of n channels, the time-frequency resources corresponding to a certain channel have been pre-configured by the network device, or there are other higher priority transmissions on a certain channel. In some embodiments, the time-frequency resources of a certain channel have been PDCCH scheduled with CRC scrambled by Cell Radio Network Temporary Identifier (C-RNTI), or Modulation and Coding Scheme C-RNTI (MCS-C-RNTI), or Configured Scheduling RNTI (CS-RNTI), or Group RNTI (G-RNTI), or Group Configured Scheduling RNTI (G-CS-RNTI), or Multicast Control Channel RNTI (MCCH-RNTI), or scheduled by SPS, etc.

[0531] In some embodiments, the TBS corresponding to one or more of the n channels may use the method shown in step 210 or step 310. It should be noted that the method shown in step 210 or step 310 is optional for the embodiments of the present application, that is, the TBS corresponding to one or more of the n channels may not use the method shown in step 210 or step 310.

[0532] In this application, the perception result includes at least one of the following: detection results of the target, detection results of the environment, recognition results of the target, recognition results of the environment, measurement results of the target, and measurement results of the environment. Among them, measurement includes at least one operation of measuring distance, measuring delay, measuring angle, measuring movement speed, and measuring phase.

[0533] In some embodiments, perception can be equivalent to or replaced by at least one of the following: positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0534] It should be noted that the above step 1210 is an optional step. Step 1210 can be implemented independently as a configuration method.

[0535] In summary, the method provided in this embodiment, since n channels occupy more time-frequency resources, the second signal carried by n channels can meet the perception requirements, and the constraint conditions effectively improve the transmission efficiency of n channels. The method provided in this embodiment avoids the waste caused by n channels occupying too many transmission resources, and also avoids the reduction of perception accuracy and communication quality caused by n channels occupying unreasonable transmission resources, thereby achieving a balance between perception requirements and communication requirements. In addition, the RV number and / or HARQ ID of the transmission block carried by n channels can be flexibly adjusted according to different orders, making full use of the time-frequency resources of n channels, so that the transmission of the transmission block can obtain retransmission gain, encoding and decoding gain, and coverage gain. The method provided in this embodiment not only saves the control overhead of n channels through the constraint conditions, but also improves the reliability and perception accuracy of n channel transmission.

[0536] In some embodiments, step 810 or step 910 can be implemented as step 1320a, and step 1010 or step 1110 can be implemented as step 1320b. In addition to step 1320a or step 1320b, the channel transmission method may also include step 1310. As shown in Figure 13, Figure 13 shows a flow chart of the channel transmission method provided by some exemplary embodiments of the present application. Taking the method as an example of being executed by a network device, a schematic description is given. Among them, the network device is implemented as a second node as shown in Figure 10 or Figure 11, or the network device is implemented as a first node as shown in Figure 8 or Figure 9. The method includes at least some of the following steps:

[0537] Step 1310: Send second information, where the second information is used to indicate a second parameter;

[0538] In some embodiments, the second parameter includes at least one of the following:

[0539] Time domain resources of at least some of the n channels;

[0540] Frequency domain resources of at least some of the n channels;

[0542] The frequency domain spacing between the frequency domain resources of at least two channels;

[0543] Maximum number of HARQ processes for n channels;

[0544] HARQ IDs of at least some of the n channels;

[0545] RV numbers of at least some of the n channels;

[0546] First order;

[0547] · Second order.

[0548] In some embodiments, the second parameter includes the time slots corresponding to the n channels. Alternatively, the second parameter indicates the time slot corresponding to channel A among the n channels and indicates the time slot intervals between the other channels and channel A. The other channels refer to the channels other than channel A among the n channels. The time slot can be replaced with other time domain units. The time slot is used as an example here only and is not intended to be limiting.

[0549] In some embodiments, the second parameter includes the PRBs corresponding to the n channels. Alternatively, the second parameter indicates the PRB corresponding to channel A among the n channels and indicates the frequency domain spacing between the other channels and channel A. The other channels refer to the channels other than channel A among the n channels. The PRB can be replaced by other frequency domain units, such as at least one of a carrier, a BWP, a subband, a subchannel, a subcarrier, or a unit based on other frequency domain units. PRB is used as an example only and is not intended to be limiting.

[0550] In some embodiments, the second information is DCI.

[0551] In some embodiments, the second information is the same as the first information, or the second information is different from the first information.

[0552] In some embodiments, the second parameters corresponding to different channels in the n channels are the same, and / or the second parameters corresponding to different channels in the n channels are different. In some embodiments, the second parameters corresponding to different channels in the n channels can be configured uniformly or individually.

[0553] In some embodiments, the n channels correspond to the same time slot. Alternatively, the time domain resources corresponding to the n channels are located in the same time slot set, where the time slot set includes one or more time slots. Alternatively, the n channels correspond to different time slots, and the time slot interval between the time slots corresponding to the n channels is less than a first threshold. Alternatively, some of the n channels correspond to the same time slot, while another portion of the n channels correspond to different time slots, and the time slot interval between the time slots corresponding to the n channels is less than the first threshold. The time slot can be replaced with other time domain units, and the time slot is used as an example here only and is not intended to be limiting.

[0554] It can be understood that by limiting the time domain resources of n channels, the second node can send n channels in a shorter time, thereby ensuring the effectiveness of the second signal carried by the n channels for obtaining the second perception result, so that the second perception result has higher perception precision and accuracy.

[0555] In some embodiments, the time domain resource corresponding to a channel includes at least one time domain unit, and the at least one time domain unit is continuous or discontinuous. Wherein, a channel is one channel among n channels.

[0559] In some embodiments, the second signal includes at least one of the following signals: DMRS; SRS; E-SRS; CPRS; CSI-RS.

[0560] In some embodiments, the second signal may be implemented as any one or more REs, or the second signal may be a signal formed by any one or more REs, or the second signal may be a signal carried by any one or more REs.

[0561] In some embodiments, the second signal is a data signal. Alternatively, the second signal is a signal in a transmission block carried by n channels.

[0562] In some embodiments, the second signal may be a signal for performing a perception service, or a signal for performing a perception operation, or a signal for achieving a perception goal, or a signal for obtaining a perception result, or a signal designed in the future for performing a perception service, or a signal designed in the future for performing a perception operation, or a signal designed in the future for achieving a perception goal, or a signal designed in the future for obtaining a perception result.

[0564] In some embodiments, the network device measures the second signal carried by n channels to obtain a second perception result.

[0565] It should be understood that when the second signal and / or transmission block is sent by the terminal device to the network device, the network device obtains the second perception result based on the second signal carried by the n channels. That is, when the network device is the first node shown in Figure 8 or Figure 9, the network device performs step 1220a.

[0566] For details about the constraints, please refer to step 910 and will not be described in detail here.

[0567] Step 1320b: Send a second signal on n channels that meet the constraint condition, where the second signal is used to obtain a second perception result.

[0568] In some embodiments, the second signal includes at least one of the following signals: DMRS; SRS; E-SRS; CPRS; CSI-RS.

[0569] In some embodiments, the second signal may be implemented as any one or more REs, or the second signal may be a signal formed by any one or more REs, or the second signal may be a signal carried by any one or more REs.

[0572] In some embodiments, the network device sends the second signal on n channels; or, the network device sends a transmission block on n channels, the transmission block including the second signal; or, the network device sends the second signal and the transmission block on n channels.

[0573] It should be understood that when the second signal and / or transmission block is sent by the network device to the terminal device, the terminal device obtains the second perception result based on the second signal carried by the n channels.

[0586] In some embodiments, the n channels include channel A, channel B, channel C, and channel D. Channel A, channel B, channel C, and channel D are arranged from front to back or from back to front in the time domain.

[0587] In some embodiments, the n channels include at least two fourth channels, the at least two fourth channels repeatedly transmit the first transport block, and the RV numbers corresponding to the first transport blocks carried by the at least two fourth channels are arranged in a first order.

[0588] For details about the constraints, please refer to step 910 and will not be described in detail here.

[0589] In some embodiments, the n channels include at least two fourth channels, the at least two fourth channels repeatedly transmit the first transport block, and the first transport blocks in different fourth channels correspond to different RV numbers.

[0597] It can also be understood that each channel in the fourth channel is distinguished by a different RV number, and each channel in the fifth channel is distinguished by a different HARQ ID.

[0598] For details about the fourth channel and the fifth channel, please refer to the embodiment shown in FIG12 , which will not be described in detail here.

[0599] In some embodiments, if the time-frequency resources corresponding to a certain channel are unavailable, the unavailable time-frequency resources can be skipped for resource mapping based on the agreement of the communication protocol, or no transmission can be performed on the channel.

[0601] In some embodiments, perception can be equivalent to or replaced by at least one of the following: positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0602] It should be noted that the above step 1310 is an optional step and can be implemented independently as a configuration method.

[0603] In summary, the method provided in this embodiment, since n channels occupy more time-frequency resources, the second signal carried by n channels can meet the perception requirements, and the constraint conditions effectively improve the transmission efficiency of n channels. The method provided in this embodiment avoids the waste caused by n channels occupying too many transmission resources, and also avoids the reduction of perception accuracy and communication quality caused by n channels occupying unreasonable transmission resources, thereby achieving a balance between perception requirements and communication requirements. In addition, the RV number and / or HARQ ID of the transmission block carried by n channels can be flexibly adjusted according to different orders, making full use of the time-frequency resources of n channels, so that the transmission of the transmission block can obtain retransmission gain, encoding and decoding gain, and coverage gain. The method provided in this embodiment not only saves the control overhead of n channels through the constraint conditions, but also improves the reliability and perception accuracy of n channel transmission.

[0604] FIG14 is a flow chart illustrating a channel transmission method provided by some exemplary embodiments of the present application. This method is illustrated by taking the terminal device shown in FIG6 and the network device shown in FIG7 as an example. The method includes at least some of the following steps:

[0605] Step 1401: The network device configures a first coefficient set for the terminal device;

[0606] The first coefficient set includes one or more set elements.

[0607] In some embodiments, the first coefficient set is configured by the network device; or, the first coefficient set is configured by the network device based on capability information reported by the terminal device; or, the first coefficient set is agreed upon by a communication protocol.

[0608] In some embodiments, the first coefficient set includes z set elements, where z is an integer greater than or equal to 1, and each set element is a positive number. In some embodiments, the first coefficient set includes 4 set elements, and the first coefficient set = {1, 0.5, 0.25, 0.125}. It should be understood that the values ​​of each set element in the first coefficient set can also be positive numbers such as 2, 3, 2.5, 4, 0.3, 0.9, and {1, 0.5, 0.25, 0.125} does not limit the values ​​of the set elements.

[0609] Step 1402: The network device sends first information to the terminal device, where the first information is used to indicate a first parameter;

[0610] In some embodiments, the first parameter includes at least one of the following: a first coefficient, the value of the first coefficient is greater than 1, or the value of the first coefficient is greater than 0 and less than 1; the number of RBs occupied by the first signal; the number of time domain units occupied by the first signal; the number of REs occupied by the first signal; and the first overhead number of the perception function scheduling.

[0611] The first coefficient may be called a scaling factor, an expansion factor, an adjustment factor, a scaling factor, an expansion factor, or an adjustment factor.

[0612] In some embodiments, before executing step 1402, the network device receives capability information reported by the terminal device, and the network device configures the first parameter based on the capability information.

[0613] In some embodiments, the first information includes DCI and / or higher layer signaling.

[0614] In some embodiments, the first information includes a first coefficient field, and the first coefficient field is used to indicate the value of the first coefficient F. In some embodiments, the first coefficient field corresponds to m bits, where m is an integer greater than or equal to 0.

[0615] In some embodiments, there is a mapping relationship or a one-to-one correspondence between the values ​​of the first coefficient field and the values ​​of the first coefficient. For example, when the bit codeword of the first coefficient field is the first codeword, the value of the first coefficient is the first value. In some embodiments, when the bit codeword of the first coefficient field is p1, the value of the first coefficient is q1; when the bit codeword of the first coefficient field is p2, the value of the first coefficient is q2. Wherein, p1 is different from p2, q1 is different from q2, and q1 and q2 both belong to the first coefficient set.

[0616] In the embodiment of the present application, taking m=2 as an example, a corresponding relationship between a first coefficient field and a first coefficient is exemplarily provided, as shown in Table 1.

[0617] Table 1 Correspondence between the first coefficient domain and the first coefficient

[0618] It should be noted that the values ​​of the first coefficients shown in Table 1 are only examples and are not limiting. The values ​​of the first coefficients may also be positive numbers such as 2, 3, 2.5, 4, 0.3, 0.9, etc.

[0619] Similarly, the values ​​of the first coefficients corresponding to the various bit codewords shown in Table 1 are only examples and are not limiting. For example, "00" can correspond to 0.125, "01" can correspond to 0.5, "10" can correspond to 1, "11" can correspond to 0.5, and so on. Not all possibilities are listed here. However, it should be understood that any bit codeword corresponding to m bits can correspond one-to-one to a set element in the first coefficient set. Even in the absence of the first coefficient set, that is, when the network device does not configure the first coefficient set for the terminal device, any bit codeword corresponding to m bits can correspond one-to-one to a positive number.

[0620] Moreover, each row in Table 1 can be used alone, for example, only "00" is used to indicate that the value of the first coefficient is 1, only "01" is used to indicate that the value of the first coefficient is 0.5, only "10" is used to indicate that the value of the first coefficient is 0.25, and only "11" is used to indicate that the value of the first coefficient is 0.125. Any two or any three rows in Table 1 can be used in combination, for example, "00" is used to indicate that the value of the first coefficient is 1, and "01" is used to indicate that the value of the first coefficient is 0.5; "10" is used to indicate that the value of the first coefficient is 0.25, and "11" is used to indicate that the value of the first coefficient is 0.125; "01" is used to indicate that the value of the first coefficient is 0.5, and "10" is used to indicate that the value of the first coefficient is 0.25, and "11" is used to indicate that the value of the first coefficient is 0.125; and so on. They are not listed here one by one.

[0621] Step 1403: The network device determines the TBS based on the first parameter;

[0622] In some embodiments, the DCI format adopted by the DCI included in the first information is DCI format 1-0, or DCI format 0-1.

[0623] The method for determining TBS may refer to the relevant content in step 640, which is schematically illustrated here with two examples.

[0624] Example 1:

[0625] Take the channel as PDSCH, and the first information includes DCI format 1-0 and high-level signaling as an example. The network device schedules PDSCH to transmit data through DCI format 1-0, and implicitly triggers the perception function by configuring the channel overhead in the transmission resource through high-level parameters. That is, the network device configures the channel overhead through high-level parameters. It is the first overhead number, which includes the number of REs occupied by control information such as synchronization channel, PBCH, PDCCH, PUCCH, and the number of REs occupied by control information used to perceive the service or the first signal.

[0626] The first parameter includes a first coefficient F, The first number includes the first coding rate R1, the modulation order Q m , number of transmission layers υ, number of first REs N RE 1. Then, it can be determined that Then, N can be determined RE 2=min(156,N′ RE 2)×n PRB , where n PRB The number of PRBs allocated to the channel by the network device. Then, N info =N RE 2×R1×F×Q m ×υ, or N info =N RE 2×R1 / F×Q m ×υ.

[0627] If N info ≤X, determine TBS by quantitative table lookup; if N info > X, TBS is determined by quantitative calculation, where X is a positive integer specified in the communication protocol. In some embodiments, X = 3824. Of course, X can also be larger or smaller than 3824.

[0628] In some embodiments, the TBS is determined by looking up a table or calculating in a relevant section of a relevant protocol of 3GPP.

[0629] Example 2:

[0630] For example, the PUSCH channel includes DCI format 0-1 and higher-layer signaling. The DCI schedules PUSCH data transmission and meets perception requirements by transmitting CPRS near multiple frequencies. The first information activates multiple carriers and / or multiple BWPs using higher-layer parameters.

[0631] The first parameter includes the first coefficient F, the number of REs occupied by the first signal The first number includes the first coding rate R1, the modulation order Q m , the number of transmission layers υ. Then, we can determine Then, N can be determined RE 2=min(156,N′ RE 2)×n PRB , where n PRB is the total number of PRBs required for the first signal transmission. info =N RE 2×R1×Qm ×υ×F, or, N info =N RE 2×R1×Q m ×υ÷F.

[0632] If N info ≤X, determine TBS by quantitative table lookup; if N info > X, TBS is determined by quantitative calculation, where X is a positive integer specified in the communication protocol. In some embodiments, X = 3824. Of course, X can also be larger or smaller than 3824.

[0633] In some embodiments, the TBS is determined by looking up a table or calculating in a relevant section of a relevant protocol of 3GPP.

[0634] Step 1404: The network device sends a transmission block and / or a first signal to the terminal device on the channel;

[0635] The TBS of the transmission block sent by the network device is the TBS determined in step 1003, and the first signal is used to obtain the first perception result.

[0636] Step 1405: The terminal device determines the TBS based on the first parameter;

[0637] The terminal device determines the content of the TBS, which can be referred to in step 1403 and will not be repeated here.

[0638] Step 1406: The terminal device receives a transport block through a channel based on the TBS.

[0639] The TBS of the transport block received by the terminal device is the TBS determined in step 1405 .

[0640] Step 1407: The terminal device obtains a first perception result based on the first signal.

[0641] In some embodiments, the terminal device measures the first signal and obtains a first perception result based on the measurement result.

[0642] In some embodiments, the first signal includes at least one of the following signals: DMRS; SRS; E-SRS; CPRS; CSI-RS; or a data signal.

[0643] In some embodiments, the perception result includes at least one of the following: a detection result of a target, a detection result of an environment, a recognition result of a target, a recognition result of an environment, a measurement result of a target, and a measurement result of an environment. The measurement includes at least one of distance measurement, delay measurement, angle measurement, movement speed measurement, and phase measurement.

[0644] In some embodiments, perception can be equivalent to or replaced by at least one of the following: positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0645] It should be noted that steps 1401, 1402, 1404, 1406, and 1407 are optional. The order of executing the steps can be adjusted according to actual conditions. For example, step 1403 can be executed before step 1401, or step 1403 can be executed before step 1402, step 1405 can be executed before step 1404, or step 1405 can be executed before step 1403.

[0646] In summary, the method provided in this embodiment satisfies the perception requirement through the first signal carried by the channel. At the same time, considering that if the channel occupies more time-frequency resources to meet the perception requirement, the TBS of the transport block carried by the channel will also increase accordingly, a solution is designed to ensure wireless communication quality by determining the TBS based on the first parameter. Compared with filling a large number of redundant bits in the transport block with an increased TBS, the method provided in this embodiment uses the first parameter to effectively adjust the transmission parameters of the channel, such as reducing the coding rate and the amount of intermediate information. This ensures that the transport block with an increased TBS carries more valid bits rather than a large number of redundant bits, reducing the transmission of redundant bits in the channel, improving the reliability, robustness, and efficiency of channel transmission, and achieving a balance between perception and communication requirements. Furthermore, it supports terminal devices reporting capability information to assist network devices in configuring the first parameter, so that the transport block / first signal carried by the channel is more consistent with the receiving capabilities of the terminal device, thereby improving the communication efficiency and transmission quality of the communication system.

[0647] FIG15 is a flow chart illustrating a channel transmission method provided by some exemplary embodiments of the present application. This method is illustrated by taking the terminal device shown in FIG12 and the network device shown in FIG13 as an example. The method includes at least some of the following steps:

[0648] Step 1501: The network device sends second information, where the second information is used to indicate a second parameter.

[0649] In some embodiments, the second parameter includes at least one of the following: time domain resources of at least part of the n channels; frequency domain resources of at least part of the n channels; time domain interval between the time domain resources of at least two channels; frequency domain interval between the frequency domain resources of at least two channels; maximum number of HARQ processes of n channels; HARQ ID of at least part of the n channels; RV number of at least part of the n channels; first order; second order.

[0650] For other contents, please refer to step 1310 and will not be repeated here.

[0651] Step 1502: The network device sends a second signal and n transmission blocks on n channels that meet the constraint conditions;

[0652] For related content, please refer to step 1320b, which will not be repeated here.

[0653] The network device performs at least one of the following operations on each of the n transmission blocks: adding a CRC code, channel coding, rate matching, etc.

[0654] The network device maps n transport blocks to n channels one by one and sends n transport blocks through n channels. Each transport block has its own corresponding RV number and / or HARQ ID.

[0655] In some embodiments, as shown in FIG16 , n is 7, and the n channels occupy the same time domain resources. The n channels are arranged from low to high in the frequency domain, namely SH 1, SH 2, SH 3, SH 4, SH 5, SH 6, and SH 7.

[0656] Alternatively, as shown in FIG17 , n is 7, the time domain resources occupied by the n channels belong to the same time domain resource set, and / or the time domain interval between the time domain resources occupied by the n channels is less than a first threshold. The n channels are arranged from low to high in the frequency domain and from front to back in the time domain.

[0657] Assume that the maximum number of HARQ processes y indicated by the second information is 2, then the second order is 0, 1. Assume that the first order is 3, 1, 0, 2.

[0658] Then, the RV numbers and HARQ IDs of the n transport blocks carried by n channels are: the HARQ ID of SH 1 is 0, and the RV number of SH 1 is 3; the HARQ ID of SH 2 is 1, and the RV number of SH 2 is 3; the HARQ ID of SH 3 is 0, and the RV number of SH 3 is 1; the HARQ ID of SH 4 is 1, and the RV number of SH 4 is 1; the HARQ ID of SH 5 is 0, and the RV number of SH 5 is 0; the HARQ ID of SH 6 is 1, and the RV number of SH 4 is 0; the HARQ ID of SH 7 is 0, and the RV number of SH 4 is 2.

[0659] FIG16 shows the RV number and HARQ ID of the transport block carried by each channel when n channels occupy the same time domain resources.

[0660] FIG17 shows the RV number and HARQ ID of the transport block carried by each channel when n channels occupy different time domain resources.

[0661] Step 1503: The terminal device obtains a second perception result based on the second signal carried by the n channels that meet the constraint condition.

[0662] In some embodiments, the terminal device measures the second signal carried by n channels and obtains a second perception result based on the measurement result.

[0663] In some embodiments, the second signal includes at least one of the following signals: DMRS; SRS; E-SRS; CPRS; CSI-RS; or a data signal.

[0664] In some embodiments, the second perception result corresponds to a perception operation; and / or, the second perception result corresponds to a perception task; and / or, the second perception result corresponds to a perception target; and / or, the second perception result corresponds to a perception measurement; and / or, the second perception result corresponds to a perception estimation; and / or, the second perception result is transmitted through a channel; and / or, the second perception result includes n groups of information, one group of information in the n groups of information is obtained based on one channel among n channels; and / or, the second perception result includes a group of information.

[0665] In some embodiments, the perception result includes at least one of the following: a detection result of a target, a detection result of an environment, a recognition result of a target, a recognition result of an environment, a measurement result of a target, and a measurement result of an environment. The measurement includes at least one of distance measurement, delay measurement, angle measurement, movement speed measurement, and phase measurement.

[0666] In some embodiments, perception can be equivalent to or replaced by at least one of the following: positioning, ranging, speed measurement, angle measurement, target imaging, target detection, target tracking, and target recognition.

[0667] It should be noted that the above steps 1501 and 1503 are optional steps. The execution order of the above steps can be adaptively adjusted according to actual conditions. The above steps can be used alone or in combination, for example: step 1501 is implemented as a configuration method alone, or step 1503 is implemented as a perception method alone, step 1501 and step 1502 are combined to implement a transmission method, or step 1502 and step 1503 are combined to implement a perception method, and so on. The above steps can be split, for example: step 1501 is split into a step of sending second information for indicating a first parameter, and a step of sending second information for indicating a third parameter; or step 1502 is split into a step of sending n transmission blocks separately.

[0668] In summary, the method provided in this embodiment, since n channels occupy more time-frequency resources, the second signal carried by n channels can meet the perception requirements, and the constraint conditions effectively improve the transmission efficiency of n channels. The method provided in this embodiment avoids the waste caused by n channels occupying too many transmission resources, and also avoids the reduction of perception accuracy and communication quality caused by n channels occupying unreasonable transmission resources, thereby achieving a balance between perception requirements and communication requirements. In addition, the RV number and / or HARQ ID of the transmission block carried by n channels can be flexibly adjusted according to different orders, making full use of the time-frequency resources of n channels, so that the transmission of the transmission block can obtain retransmission gain, encoding and decoding gain, and coverage gain. The method provided in this embodiment not only saves the control overhead of n channels through the constraint conditions, but also improves the reliability and perception accuracy of n channel transmission.
