Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to terminals, network devices, and communication methods. Background Technology

[0002] With the development of communication technology, the application of high-frequency spectrum resources in new radio (NR) communication technology has become an effective way to achieve high-data-rate communication.

[0003] In the high-frequency band, to overcome path fading and increase coverage, network devices and terminals typically use beamforming for communication. This means that the network device or terminal simulates weighting of its multiple antenna elements, amplifying the energy of the weighted signal in a specific direction, and then transmitting or receiving signals from the other end in that direction.

[0004] In practical applications, the terminal can use beamforming to send uplink data channels to network devices. Furthermore, the terminal can transmit uplink control information on this uplink data channel.

[0005] Because high-frequency communication uses shorter wavelengths, its signal diffraction capability is poor, making it susceptible to obstructions. When uplink control information is transmitted across the beam, obstructions can cause a degradation in link quality, thus reducing the reliability of control information transmission.

[0006] The terminal uses a beamforming method, and how to reliably transmit uplink control information over the uplink data channel is a problem that needs to be solved. Summary of the Invention

[0061] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0062] An exemplary structural diagram of a communication system to which the communication method of the embodiments of this application can be applied is shown below. Figure 1 As shown. It should be understood that the embodiments of this application are not limited to those shown. Figure 1 In the system architecture shown, in addition, Figure 1 The device in the document can be hardware, software based on function, or a combination of both.

[0063] from Figure 1 It is understood that a communication system that can apply the communication method of the embodiments of this application may include a network device 110 and a terminal 120.

[0064] Network device 110 can be a base station. It should be understood that the specific type of base station is not limited in the embodiments of this application. In systems employing different wireless access technologies, the names of devices with base station functions may differ. For ease of description, in all embodiments of this application, the aforementioned devices providing wireless communication functions for terminals are collectively referred to as base stations, such as base station equipment or small cell equipment (pico) in future networks.

[0065] Terminal 120 can be user equipment (UE). The UE can communicate with one or more core networks via a radio access network (RAN). The UE can be referred to as an access terminal, terminal equipment, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication equipment, user agent, or user device. The UE can be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device, or other device connected to a wireless modem, in-vehicle equipment, wearable device, or terminal equipment in the Internet of Things (IoT), vehicular networks, and any form of terminal equipment in future networks.

[0066] exist Figure 1 In the communication system shown, network device 110 and terminal 120 can transmit data to each other on high-frequency resources using beamforming.

[0067] The shorter wavelengths in high-frequency bands allow for smaller antenna spacing, enabling the placement of more antenna elements within the same area. A large number of antenna elements can form a large-scale array antenna. This large-scale array antenna can utilize beamforming to increase array gain, effectively enhancing coverage and overcoming path attenuation in the high-frequency band.

[0068] For large-scale antenna arrays, it is not feasible to connect every antenna element to a radio frequency (RF) channel from a cost perspective. With a limited number of RF channels, by using a phase shifter at the RF end, analog phase weighting can be achieved, thereby forming an analog beam at the RF end.

[0069] Analog beams can be formed in network devices or at terminals. Network devices or terminals can enhance the energy of a signal in a certain direction by changing the phase weights of the antenna array elements, thus improving their ability to receive or transmit signals in that direction. The antenna port that transmits the enhanced signal in that direction can be called a beam; that is, network devices or terminals can transmit beams in different directions or receive beams in different directions.

[0070] For high-frequency bands, analog beamforming or a hybrid analog-digital weighted approach can be used to meet coverage requirements.

[0071] If analog beamforming or hybrid beamforming is used for communication, then for the same antenna panel, when transmitting information on multiple beams, these multiple beams are transmitted in a time-division manner. In other words, if analog beamforming or hybrid beamforming is used for communication, for the same antenna panel, only one analog beam can be formed at a time, pointing in one direction, i.e., covering a certain area.

[0072] For example, a large number of antenna array elements can be set on network device 110 and terminal 120. When terminal 120 sends information to network device 110 (such as uplink data information or uplink control information), terminal 120 can set a phase shifter on its own radio frequency terminal. By changing the phase weight of the antenna array elements through the phase shifter, the simulated phase weighting of multiple antenna array elements is realized, which enhances the signal capability in the direction of the network device and forms a simulated beam aligned with network device 120. The network device 110 sends information through this simulated beam.

[0073] Correspondingly, network devices can also set up phase shifters at their own radio frequency terminals. By changing the phase weights of the antenna array elements through the phase shifters, the simulated phase weighting of multiple antenna array elements can be achieved to form a receiving beam to receive the information sent by the terminal 120.

[0074] Similarly, as the reverse process of uplink transmission, when the network device sends information (i.e., downlink data information or downlink control information) to the terminal 120, the above communication method can also be used, which will not be repeated here.

[0075] In the embodiments of this application, a beam can be understood as a spatial resource. Different beams can be considered as different spatial resources. Unlike the beams in LTE, the beams in the embodiments of this application are mainly analog beams, that is, only one analog beam can be formed on an antenna panel at the same time. If the terminal or network device only has one antenna panel, when multiple beams need to be transmitted, different beams can only be transmitted in a time-division manner.

[0076] The technical solution of this application is applicable not only to scenarios using different beams for transmission, but also to scenarios using different port resources for transmission. This is because a port itself is a logical resource identifier that can be used to distinguish different spatial resources, and thus, different beams.

[0077] In this application, different spatial resources can have different quasi-co-located (QCL) information. QCL information is generally used to indicate the relationship between reference signal ports. In beamforming communication, before data transmission using uplink beams, beam pairing scanning is required. The terminal needs to send an uplink reference signal to scan the beams to determine the transmit beam used by the terminal and the receive beam used by the network device when transmitting data. This reference signal can be a sounding reference signal (SRS) or other reference signals. When beam-based correspondence or reciprocity exists for the terminal, this reference signal can also be a downlink reference signal. Reciprocity means that the uplink beam of the terminal can be determined based on the downlink scanning results; that is, the optimal receive beam determined by the terminal through downlink beam scanning corresponds to the optimal uplink transmit beam.

[0078] The QCL information in this application can be a parameter describing spatial relationships, such as the angle-of-departure (AOD) or the spatial correlation of the transmit beam antenna. When actually using a certain beam for data communication, if the terminal obtains the QCL information, it can determine the corresponding transmit beam using the QCL information. For example, it can determine that the port of the demodulation reference signal (DMRS) of the physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) is QCL-compliant with the port of the SRS during a previous scan; that is, the beam direction of the PUSCH or PUCCH is the same as the beam direction of a previous SRS. In this application, when multiple beams are needed for transmission, beams with different directions are required; therefore, different beams have different QCL information.

[0079] It should be noted that, Figure 1 This is merely an illustrative diagram, and the number of network devices 110 and terminals 120 does not limit the solution provided in this application. In practical applications, different numbers can be used. Figure 1 The number shown is used for network deployment.

[0080] Furthermore, the solution provided in this application can also be applied to other than Figure 1 This application does not limit the scope of any other communication system that uses beamforming for communication.

[0081] The following embodiments in this application are only for illustrative purposes. Figure 1Taking the communication system shown as an example, the communication method, network equipment and terminal provided in this application will be described.

[0082] Figure 2 This is a schematic flowchart illustrating a communication method according to one embodiment of this application. It should be understood that... Figure 2 The steps or operations of the communication method are illustrated, but these steps or operations are merely examples, and other operations may be performed in the embodiments of this application. Figure 2 Variations of various operations within it. Furthermore... Figure 2 The various steps in can be followed according to Figure 2 The different orders in which they are presented may be executed, and it is possible that they are not intended to be executed. Figure 2 All operations within.

[0083] S220, the terminal uses multiple spatial resources from the first spatial resource set to send first uplink control information. Correspondingly, the network device receives the first uplink control information.

[0084] The first spatial resource set can be pre-configured on the terminal. Specifically, both the terminal and the network device can be configured with the first spatial resource set, which can include indexes or identification information of multiple spatial resources.

[0085] In this communication method, the terminal uses multiple spatial resources to send the first uplink control information. When the uplink control information transmitted on some of the spatial resources is affected, the other spatial resources can still transmit the uplink control information, thereby improving the transmission reliability of the uplink control information and ultimately improving the communication reliability between the terminal and the network device.

[0086] In this embodiment, the spatial resources can be beams. The first spatial resource set can be understood as the first beam set; the first spatial resource set includes multiple spatial resources, which can be understood as: the first spatial resource set includes multiple beams. Each beam has a corresponding analog phase weighting value.

[0087] The following embodiments of this application use spatial resources as a beam as an example to further describe the communication method of this application. It should be understood that beams in the following description can be replaced with ports or other names that have the same meaning as beams.

[0088] Network devices can define a first beam set as multiple beams with good communication quality (e.g., RSRP value) or low spatial correlation between the network device and the terminal. Specifically, this can be achieved by defining a first beam set as multiple beams with good communication quality or low correlation among the beams available to the terminal. Alternatively, each beam can be a beam from the transmit and receive beams that have already been paired between the network device and the terminal.

[0089] That is, the communication quality of the beams in the first beam set can be better than the communication quality of other beams that can be used for communication between network devices and terminals.

[0090] For example, if a network device and a terminal can communicate through 5 beams, but the quality of 3 of the beams is better than that of the other 2 beams, then the network device can identify these 3 beams as the first beam set.

[0091] The terminal uses a beam with better communication quality to send the first uplink control information, which can further improve the communication reliability between the terminal and network equipment.

[0092] The first uplink control information may include one or more types of information.

[0093] When the first uplink control information includes multiple types of information, it means that the beam sets of the multiple types of information are the same, and they are all the first beam set.

[0094] The first uplink control information may include a beam index (BI). After the network device sends a measurement reference signal or the terminal sends a measurement reference signal, the BI can be used to report to the network device which beams have better quality, so that the network device can schedule beams according to the measurement results.

[0095] The first uplink control information may include a beam recovery request (RR) message. In high-frequency communication systems using beamforming, if the beam is affected, such as by obstruction causing a beam interruption, the terminal can notify the network device that communication has been interrupted via an RR message. Upon receiving the RR message, the network device will take certain measures, such as switching beams, to restore communication.

[0096] The first uplink control information may include the reference signal received power (RSRP) of the beam.

[0097] The first uplink control information may also include at least one of the following: hybrid automatic repeat request-acknowledgement (HARQ-ACK), rank indicator (RI), channel quality indicator (CQI), and precoding matrix indicator (PMI). The definitions of RI, HARQ-ACK, CQI, PMI, and RSRP can be found in the definitions of the same or similar terms in LTE technology; for brevity, they will not be repeated here.

[0098] The terminal can use multiple spatial resources from the first spatial resource set to send the first uplink control information on the uplink data channel.

[0099] Figure 2 In the communication method shown, optionally, some of the resources in the first control resource set may not be pre-configured on the terminal. In this case, Figure 2 The communication method shown may further include: S210, whereby the network device sends first indication information, the first indication information being used to indicate a first set of spatial resources, the first set of spatial resources including multiple spatial resources. Correspondingly, the terminal receives the first indication information.

[0100] When the first uplink control information includes multiple types of information, the network device can save signaling, i.e., save communication resources, by instructing the terminal to send the beam set when multiple types of information are sent through a first indication information.

[0101] The first indication information may include an index of each type of information in the first uplink control information and an index of each beam in the first beam set, or an index of the beam pair to which each beam belongs, or an index of the beam group to which each beam belongs. By using index indication information and beams, signaling overhead can be saved, thereby saving communication resources.

[0102] The first indication information may also include QCL-related information, which indicates whether the ports are similar with respect to a certain spatial parameter. If the terminal can determine that the ports are similar with respect to a certain spatial parameter, then the two ports have similar spatial characteristics.

[0103] In this application, to instruct the terminal to use different transmit beams, the first indication information can carry information about the QCL (Queries Classification of Linear Adaptives) parameter between the DMRS port of PUCCH or PUSCH and the SRS port. The QCL parameter can be AOA (Area of ​​Effect) or the spatial correlation of the transmit antenna. This allows control information to be transmitted on different beams. The network device can transmit the first indication information via higher-layer signaling. Correspondingly, the terminal can receive the first indication information via higher-layer signaling.

[0104] Higher-layer signaling may include radio resource control (RRC) signaling and medium access control-control element (MAC-CE) signaling.

[0105] Network devices can send first instruction information via downlink control information, and correspondingly, terminals can receive first instruction information via downlink control information.

[0106] Figure 2 In the communication method shown, optionally, some of the resources in the first control resource set may not be pre-configured on the terminal. In this case, Figure 2 The communication method shown may further include: a network device sending downlink scheduling information, the downlink scheduling information including modulation and coding schemes for multiple time units. Correspondingly, a terminal receives the downlink scheduling information. After receiving the downlink scheduling information, the terminal can determine the modulation and coding scheme that meets a certain condition among the multiple time units, such as a modulation and coding scheme greater than a certain threshold, and determine that the beams corresponding to the transmission blocks using that modulation and coding scheme value within the multiple time units form a first beam set.

[0107] In other words, the beams in the first beam set mentioned in S220 are the beams used when transmitting the first transmission block, and the modulation and coding scheme of the first transmission block is the modulation and coding scheme that satisfies the first condition among the modulation and coding schemes of the above multiple time units.

[0108] In this embodiment, the terminal uses the beam corresponding to the transmission block whose modulation and coding scheme value satisfies the first condition in multiple time units to send the first uplink control information, which can further improve the communication reliability of the first uplink control information.

[0109] The first condition can be pre-configured on the terminal, such as by configuring according to communication standards or by configuring according to configuration information sent by network devices.

[0110] The first condition can specifically be that the modulation and coding scheme value is the highest, that is, the modulation and coding scheme value of the first transmission block is the highest among the modulation and coding schemes of the above multiple time units.

[0111] In this context, a time unit can be a subframe, meaning that the downlink scheduling information can include the modulation and coding schemes of multiple subframes. It should be understood that each subframe can have multiple modulation and coding schemes.

[0112] like Figure 3 In the two subframes shown, each subframe includes 7 symbols. The first subframe is a bidirectional subframe, and the second subframe is a full uplink subframe. The downlink symbols of the first subframe carry the scheduling information of these two subframes.

[0113] At this point, the terminal can receive the modulation and coding scheme information of these two subframes in the scheduling information of the first downlink subframe. Then, the terminal can determine which of the two subframes has a larger modulation and coding scheme, and send the first uplink control information through the beam corresponding to the transport block using the larger modulation and coding scheme.

[0114] The terminal can be pre-configured, such as according to the standard configuration as follows: when there are multiple modulation and coding schemes with the highest value, that is, when there are multiple transmission blocks with the highest modulation and coding scheme value, the first uplink control information can be sent using the beam with the earliest time in the beam corresponding to the transmission block with the highest modulation and coding scheme value.

[0115] When each time unit is not centrally scheduled, it is necessary to indicate the first beam set when sending the first uplink control information. For example... Figure 4 As shown, it contains 2 subframes, each with 7 symbols. Each subframe contains its own scheduling information. Therefore, when the network device schedules the uplink data channel of the terminal on multiple subframes, it can send indication information to the terminal to indicate on which subframe the first uplink control information will be transmitted.

[0116] Figure 2 In the communication method shown or in various possible implementations of the communication method, the first beam set may be a subset of the second beam set. The second beam set includes multiple beams that the terminal can use when sending second uplink control information, which is of a different type from the first uplink control information.

[0117] For example, the second uplink control information may include at least one of HARQ-ACK, RR, RI, BI, and RSRP; the first uplink control information may include at least one of BI, RSRP, CQI, and PMI other than the information included in the first uplink control information.

[0118] The multiple beams included in the second beam set can be used to transmit second uplink control information, which can be configured on the terminal or indicated by the network device. If it is indicated by the network device, then... Figure 2 The communication method shown, or various possible implementations thereof, may also include: the network device sending second indication information, the second indication information being used to instruct the terminal to send a second beamset when sending second uplink control information. Accordingly, the terminal receives the second indication information.

[0119] In this context, the importance of various information items in the second uplink control information can be higher than that in the first uplink control information. In other words, the impact of various information items in the second uplink control information on the communication between the terminal and the network device is greater than that of various information items in the first uplink control information.

[0120] In this case, the second beam set includes more beams, meaning the terminal can use more beams to send high-importance second uplink control information, thereby improving the communication reliability of the second uplink control information. The first beam set includes fewer beams, meaning the terminal can use fewer beams to send low-importance first uplink control information, thereby saving communication resources.

[0121] Network devices can send second instruction information via higher-layer signaling. Correspondingly, terminals can receive the second instruction information via higher-layer signaling.

[0122] Higher-layer signaling may include RRC signaling and medium access control-control element (MAC-CE) signaling.

[0123] Network devices can send second instruction information via downlink control information, and correspondingly, terminals can receive second instruction information via downlink control information.

[0124] The second uplink control information may include one or more types of information.

[0125] When the second uplink control information includes multiple types of information, it indicates that the beam sets for these multiple types of information are the same, namely the second beam set. In other words, network devices can use a single second indication message to instruct the terminal on the beam set when sending multiple types of information, thereby saving signaling and communication resources.

[0126] The second indication information may include an index of each type of information in the second uplink control information, an index of each beam in the second beam set, an index of the beam pair to which each beam belongs, or an index of the beam group to which each beam belongs. By using index indication information and beams, signaling overhead can be saved, thereby saving communication resources.

[0127] Figure 2 In the communication method shown or various possible implementations of the communication method, when the terminal uses multiple beams in the first beam set to send the first uplink control information on the uplink data channel, the terminal can perform time-domain resource mapping on the first uplink control information according to the resource mapping priority of the information included in the first uplink control information.

[0128] Prior to this, the terminal can obtain the resource mapping priority and / or resource mapping method. Then, it performs time-domain resource mapping on the first uplink control information according to the resource mapping priority and resource mapping method.

[0129] The resource mapping method and / or the resource mapping priority can be configured according to the communication standard or received from the network device.

[0130] The time-domain resource can specifically be a time-domain symbol. In this case, the resource mapping method can include: if the resource mapping priority of the information is higher, the symbol distance between the target time-domain symbol of the information and the time-domain symbol of the reference signal is smaller, and vice versa; if the resource mapping priority of the information is higher, the target time-domain symbol of the information is located before the time-domain symbol of the reference signal, and vice versa.

[0131] Alternatively, resource mapping methods may include: if the resource mapping priority of information is lower, then when the information is transmitted on fewer time domain symbols, or when it conflicts with higher priority information during mapping, the lower priority information is discarded first, and vice versa. Alternatively, it can be predefined that on resources with fewer uplink time domain symbols, only high-priority information is mapped, while on larger resources, both high-priority and low-priority information can be mapped.

[0132] For example, when the reference signal is a demodulation reference signal (DMRS), and DMRS occupies the first time-domain symbol, and the resource mapping priority is (HARQ-ACK and RR) > (RI, BI and RSRP) > (CQI and PMI) > Data resources, a resource mapping diagram obtained according to the aforementioned resource mapping method is as follows: Figure 5 As shown.

[0133] It should be understood that the above resource mapping priority is merely an example and should not constitute a limitation on the embodiments of this application. In the embodiments of this application, other resource mapping priorities may be used, such as (HARQ-ACK and RR) > (RI) > (BI, RSRP, CQI and PMI) > Data.

[0134] like Figure 5 As shown, the target time-domain symbols for HARQ-ACK and RR are placed immediately after the time-domain symbol for DMRS; the target time-domain symbols for RI and BI are on the second time-domain symbol after the time-domain symbol for DMRS; the target time-domain symbols for RSRP are on the 4th and 5th symbols after the time-domain symbol for DMRS; and the target time-domain symbols for CQI and PMI are after the target time-domain symbol for RSRP. Subsequent time-domain symbols represent the time-domain symbols that data can occupy. The information on each time-domain symbol is processed using frequency division.

[0135] When the reference signal is DMRS, DMRS occupies the second symbol in the subframe, and the resource mapping priority is (HARQ-ACK and RR) > (RI, BI and RSRP) > (CQI and PMI) > Data, a resource mapping diagram obtained according to the aforementioned resource mapping method is as follows: Figure 6 As shown.

[0136] like Figure 6 As shown, the target time domain symbol for (HARQ-ACK and RR) is the first time domain symbol, the target time domain symbol for RI and BI is the third time domain symbol, the target time domain symbol for RSRP is the fourth and fifth symbols, and the target time domain symbols for CQI and PMI are after the target time domain symbol for RSRP. The subsequent time domain symbols are the time domain symbols that the data can occupy.

[0137] Figure 6 This describes the case where a subframe has one DMRS. When slot or mini-slot aggregation is supported, each slot and mini-slot can have its own DMRS. In this case, resource mapping can be performed uniformly across multiple slots or mini-slots.

[0138] When the reference signal is DMRS, and DMRS occupies the second symbol in the subframe, and the resource mapping priority is (HARQ-ACK and RR) > (RI, BI and RSRP) > (CQI and PMI) > Data, a schematic diagram of unified resource mapping across multiple slots or minislots, based on the aforementioned resource mapping method, is shown below. Figure 7 As shown.

[0139] like Figure 7 As shown, the target time-domain symbols for ACK and RR can be near the time-domain symbol occupied by the DMRS in the first slot or mini-slot, while the target time-domain symbols for RI, CRI, and BI can be near the time-domain symbol occupied by the DMRS in the second slot or mini-slot.

[0140] When the terminal uses multiple beams in the second beam set to send the second uplink control information, it can also perform resource mapping on the second uplink control information according to the resource mapping priority. For the specific implementation method, please refer to the implementation method of the first uplink control information. For the sake of simplicity, it will not be described in detail here.

[0141] The following describes several methods for transmitting time slots.

[0142] One method for transmitting a slot may include: when a network device sends a transmission block (TB) of data to a terminal, after code block segmentation, channel coding, rate matching, and code block concatenation, the generated number of bits can be modulated using existing techniques according to the assigned modulation and coding scheme (MCS). This method differs from existing techniques in that it modulates the generated number of bits separately according to different modulation schemes. A simple way to use different modulation schemes for the number of bits is to divide them evenly and then generate corresponding modulation symbol numbers according to different modulation schemes. Interleaving of modulation symbols can also be considered before resource mapping.

[0143] In the interleaving method, if a mini-slot contains multiple time-domain symbols and the transmitted content has no latency requirements, then a cross-time-domain symbol interleaving method can be used to interleave the modulation symbols; if the transmitted content has no latency requirements, then an intra-time-domain symbol interleaving method can be used to interleave the modulation symbols. Finally, resource mapping is performed.

[0144] Correspondingly, when the terminal receives data, it first demodulates the received symbols based on the reference MCS and the offset of the MCS in the downlink control information (DCI) of the scheduling signaling, obtaining the corresponding bits. Then, based on the reference MCS in the signaling, it determines the corresponding TB size, which in turn determines the number and size of coding blocks (CBs) in the TB, thereby decoding the corresponding TB.

[0145] The advantage of this approach is that it uses different MCSs in different frequency bands to achieve frequency-selective scheduling gain. In the scheduling signaling DCI, multiple MCSs are indicated, one of which is set as the reference MCS, and the remaining MCSs are represented as relative values ​​to the reference MCS. This reduces scheduling overhead.

[0146] The differential MCS in this method uses an overhead-saving scheme to apply to the same time-domain symbol. It can be used on different subbands, different code blocks, or different code block groups. One subband corresponds to a portion of the allocated bandwidth, which corresponds to one or more CBs (CB groups). Similarly, this method can also be used in different time units. The terminal can obtain the corresponding MCS by receiving a reference MCS and a relative value.

[0147] Another method for transmitting a slot may include: when a network device transmits 1TB of data to a terminal, after code block segmentation, channel coding, rate matching, and code block concatenation, it directly modulates the data using existing techniques. This method differs from existing techniques in that it performs code block interleaving, and after interleaving, it uses the same MCS for modulation, followed by RE mapping.

[0148] In the interleaving method, if a mini-slot contains multiple time-domain symbols and the transmitted content has no latency requirements, then a cross-time-domain symbol interleaving method can be used to interleave the code blocks; if the transmitted content has no latency requirements, then an intra-symbol interleaving method can be used to interleave the code blocks. Finally, resource mapping is performed.

[0149] Correspondingly, when the terminal receives data, it demodulates the received symbols according to the MCS in the DCI of the scheduling signaling. After demodulation, it performs deinterleaving operation according to the interleaving method adopted, thereby deinterleaving the corresponding TB.

[0150] The advantage of this approach is that it involves code block interleaving to combat frequency-selective fading, while also taking into account different latency requirements.

[0151] Another method for transmitting a slot may include: when a network device transmits 1TB of data to a terminal, it performs code block segmentation, channel coding, rate matching, and code block concatenation, and uses the same MCS for modulation. After modulation, resource mapping is performed directly using existing technology. The difference between this method and existing technology is that it performs modulation symbol interleaving before resource mapping.

[0152] In the interleaving method, if a mini-slot contains multiple time-domain symbols and the transmitted content has no latency requirements, then a cross-time-domain symbol interleaving method can be used to interleave the modulation symbols; if the transmitted content has no latency requirements, then an intra-time-domain symbol interleaving method can be used to interleave the modulation symbols. After interleaving, resource mapping is performed.

[0153] The advantage of this approach is that it involves interleaving modulation symbols to combat frequency-selective fading, while also taking into account different time delay requirements.

[0154] The three schemes can also be applied to the case of sending multiple TBs, for example, different TBs correspond to different subbands.

[0155] Another method for transmitting slots may include: the network device sending configuration information about subbands to the terminal, where each subband corresponds to a portion of the allocated bandwidth, and this portion corresponds to one or more CBs (CBgroups). The configuration information may include bandwidth and the number of subbands, or the frequency domain size of the subbands and the number of subbands, or bandwidth and the frequency domain size of the subbands, or bandwidth, the frequency domain size of the subbands, and the number of subbands. The UE can obtain the corresponding subband allocation information through this configuration information, thereby determining its corresponding FFT size. As a UE capability, the UE can report the number of cells (carriers) it can support, or the number of subbands, or the number of cells and the number of subbands.

[0156] If a subband contains a code block group, then code block interleaving can be performed within the code block group. This interleaving can be performed on the encoded bits or on the modulated symbols after modulation.
