Detailed ways

Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

The uplink waveform configuration method provided by the embodiment of the present disclosure can be applied to the wireless communication system shown in Figure 1. Referring to Figure 1, the wireless communication system includes a network device and a terminal. The terminal is connected to the network device through wireless resources and performs data transmission.

It is understandable that the wireless communication system shown in FIG1 is only for schematic illustration, and the wireless communication system may also include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices, which are not shown in FIG1. The embodiments of the present disclosure do not limit the number of network devices and terminals included in the wireless communication system.

It can be further understood that the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt different communication technologies, such as code division multiple access (code division multiple access, CDMA), wideband code division multiple access (wideband code division multiple access, WCDMA), time division multiple access (time division multiple access, TDMA), frequency division multiple access (frequency division multiple access, FDMA), orthogonal frequency division multiple access (orthogonal frequency-division multiple access, OFDMA), single carrier frequency division multiple access (single carrier FDMA, SC-FDMA), carrier sense multiple access/collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). According to the capacity, rate, delay and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called new wireless network (New Radio, NR). For the convenience of description, the present disclosure sometimes simply refers to a wireless communication network as a network.

Further, the network equipment involved in the present disclosure may also be referred to as a wireless access network equipment. The wireless access network equipment may be: a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It may also be a gNB in an NR system, or it may also be a component or a part of a base station. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network equipment are not limited. In the present disclosure, the network equipment may provide communication coverage for a specific geographical area, and may communicate with a terminal located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network equipment may also be a vehicle-mounted device.

Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., which is a device that provides voice and/or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a smart phone (Mobile Phone), a customer premises equipment (Customer Premise Equipment, CPE), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

At present, uplink coverage has always been one of the performance bottlenecks of the communication system. Limited uplink coverage affects the signal quality of PUSCH, which in turn affects the user experience.

In the related technology, multiple waveforms are used to support PUSCH, such as Cyclic Prefix Orthogonal Frequency-Division Multiplexing (CP-OFDM) waveform and Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFTS-OFDM) waveform. As shown in Figure 2, the peak-to-average ratio (PAPR) of the DFTS-OFDM waveform is about 3dB lower than the PAPR of the CP-OFDM waveform. The CP-OFDM waveform can maximize the use of network capacity in densely populated cities, while the DFTS-OFDM waveform has a lower PAPR and is more suitable for scenarios with limited uplink coverage (for example, uplink coverage at the edge of a cell). Different waveforms have their own uplink coverage advantages for different scenarios.

In the related art, network equipment usually semi-statically configures the waveform used by the terminal through Radio Resource Control (RRC) signaling. On this basis, if the waveform used by the terminal needs to be changed, the RRC signaling needs to be reconfigured. It can be seen that the method of semi-statically configuring the waveform through RRC signaling in the related art has a long delay required to change the waveform, and there is a problem of inflexibility in use.

In addition, in the related art, for the PUSCH scheme, there is an enhanced multi-configuration scheme for configuring the authorized physical uplink shared channel (CG PUSCH), which is used to provide the terminal with multiple CG PUSCH configurations that can independently support PUSCH at the same time, and there is a certain time offset between different CG PUSCH configurations, which is used to provide multiple transmission opportunities in the time domain. On this basis, when the data block to be transmitted is ready, the terminal side can always select a CG PUSCH configuration for supporting transmission from multiple CG PUSCH configurations, and start transmission through the first transmission opportunity along the timing in the selected CG PUSCH configuration. Further, through the multiple transmission opportunities provided by the CG PUSCH configuration, multiple transmissions can be achieved, thereby meeting the low latency requirements and high reliability requirements at the same time. Among them, for the configuration of the transmission waveform under the current protocol, each CG PUSCH configuration is independently performed. Taking Figure 3 as an example, for the same data stream, four CG PUSCH configurations, namely configuration 1, configuration 2, configuration 3 and configuration 4, can be configured. The periods of the four CG PUSCH configurations are the same, but there is a time offset between them. On this basis, the time offset of the four CG PUSCH configurations corresponds to one transmission opportunity to ensure seamless transmission in timing, thereby minimizing latency. However, in the related art, multiple CG PUSCH configurations configured on the terminal side are usually configured to support the same specified waveform.

In view of this, the present disclosure provides an uplink waveform configuration method, which is adapted to the enhanced multi-configuration scheme of the CG PUSCH involved above, and is used to make further improvements on the basis of the enhanced multi-configuration scheme to achieve dynamic configuration of the transmission waveform. Specifically, the present disclosure configures specific CG PUSCH configuration information in the terminal, which is used to configure multiple groups of CG PUSCH configurations, and configures the multiple groups of CG PUSCH configurations to correspond to at least two different transmission waveforms. On this basis, the terminal can consider the multiple groups of CG PUSCH configurations configured by the CG PUSCH configuration information according to the CG PUSCH configuration information, and then based on the at least two transmission waveforms corresponding to the multiple groups of CG PUSCH configurations, realize the configuration of the transmission waveform used for CG PUSCH transmission.

Fig. 4 is a flow chart of an uplink waveform configuration method according to an exemplary embodiment. As shown in Fig. 4 , the method is used in a terminal and includes the following steps.

In step S11, determine the CG PUSCH configuration information.

In the disclosed embodiment, CG PUSCH configuration information is used to configure multiple groups of CG PUSCH configurations. The transmission waveforms corresponding to the multiple groups of CG PUSCH configurations include at least two different transmission waveforms, and each transmission waveform corresponds to one or more groups of CG PUSCH configurations.

In step S12, based on the CG PUSCH configuration information, the transmission waveform used for CG PUSCH transmission is configured.

In the uplink waveform configuration method provided by the embodiment of the present disclosure, multiple groups of CG PUSCH configurations corresponding to at least two different transmission waveforms are configured on the terminal side. On this basis, the terminal selects the CG PUSCH configuration corresponding to different transmission waveforms to realize the switching of the transmission waveform. Compared with the semi-static configuration method using RRC signaling in the related art, this method has better flexibility and realizes the dynamic configuration of the transmission waveform.

For example, the transmit waveform used for CG PUSCH transmission can be configured as follows.

FIG5 is a flow chart of another uplink waveform configuration method according to an exemplary embodiment. As shown in FIG5 , step S21 in the embodiment of the present disclosure is similar to the execution method of step S11 in FIG4 , and will not be described in detail herein.

In step S22, the transmission waveform used for CG PUSCH transmission is configured to be the transmission waveform corresponding to the CG PUSCH configuration used for CG PUSCH transmission.

In the disclosed embodiment, the terminal configures the transmission waveform corresponding to the CG PUSCH configuration used for CG PUSCH transmission as the transmission waveform corresponding to the CG PUSCH configuration used for CG PUSCH transmission through CG PUSCH configuration information. Accordingly, when the CG PUSCH configuration used for CG PUSCH transmission is switched, the terminal can switch the transmission waveform based on the switching of the CG PUSCH configuration, thereby realizing dynamic configuration of the transmission waveform.

In the uplink waveform configuration method provided by the embodiment of the present disclosure, the CG PUSCH configuration used by the terminal for CG PUSCH transmission can be determined by the network device or by the terminal itself. Among them, as a feasible implementation method, the terminal side can independently determine the CG PUSCH configuration used for CG PUSCH transmission, and then by reporting the corresponding CG PUSCH configuration, the network device side completes the CG PUSCH configuration of the terminal.

FIG6 is a flow chart of another uplink waveform configuration method according to an exemplary embodiment. As shown in FIG6 , step S31 and step S33 in the embodiment of the present disclosure are similar to the execution method of step S21 and step S22 in FIG5 , and are not described in detail here.

In step S32, configuration indication information is sent to the network device so that the network device configures the CG PUSCH configuration used for CG PUSCH transmission for the terminal based on the configuration indication information.

In the disclosed embodiment, the configuration indication information is generated by the terminal and is used to indicate the CG PUSCH configuration used for CG PUSCH transmission. When the terminal sends the configuration indication information to the network device, the network device can configure the CG PUSCH configuration used for CG PUSCH transmission for the terminal according to the configuration indication information.

The uplink waveform configuration method provided in the embodiment of the present disclosure can enable the terminal to autonomously determine the CG PUSCH configuration used for CG PUSCH transmission. And, it can be understood that when the terminal determines the CG PUSCH configuration to be used, it is necessary to refer to the transmission waveform used for CG PUSCH transmission. Specifically, the terminal refers to the transmission waveform used for CG PUSCH transmission, determines the CG PUSCH configuration that supports the use of the transmission waveform for CG PUSCH transmission, and then determines the CG PUSCH configuration used for CG PUSCH transmission in the CG PUSCH configuration that supports the use of the transmission waveform for CG PUSCH transmission. In the above embodiment, the transmission waveform referenced by the terminal can be determined by the network device side and notified to the terminal, or it can be determined autonomously by the terminal side.

As a feasible implementation method, for the process of the terminal sending the configuration indication information, the transmission waveform used for the CG PUSCH transmission referenced by the terminal can be sent by the network device through the waveform indication information. Among them, the waveform indication information can be understood as downlink information used to indicate the transmission waveform used by the terminal for CG PUSCH transmission.

FIG7 is a flow chart of another uplink waveform configuration method according to an exemplary embodiment. As shown in FIG7 , step S41 and step S43 in the embodiment of the present disclosure are similar to the execution method of step S31 and step S33 in FIG6 , and are not described in detail here.

In step S42, when the waveform indication information sent by the network device is received, configuration indication information is sent to the network device, so that the network device configures the CG PUSCH configuration used for CG PUSCH transmission for the terminal based on the configuration indication information.

The uplink waveform configuration method provided by the embodiment of the present disclosure is that the terminal obtains the transmission waveform used for CG PUSCH transmission determined by the network device by receiving waveform indication information, and then sends configuration indication information to the network device through the determined transmission waveform to complete the configuration process of the transmission waveform.

For example, the waveform indication information can be carried in at least one of the MAC CE signaling and the DCI signaling.

In addition, as another feasible implementation method, for the process of the terminal sending the configuration indication information, the transmission waveform used for the CG PUSCH transmission referenced by the terminal can also be determined autonomously by the terminal. For example, the terminal side can pre-configure the corresponding reporting judgment condition to send the configuration indication information when the terminal determines that the reporting judgment condition is met. Among them, the above-mentioned reporting judgment condition can be understood as the judgment condition configured for triggering the sending of the configuration indication information.

FIG8 is a flowchart of another uplink waveform configuration method according to an exemplary embodiment. As shown in FIG8 , step S51 and step S53 in the embodiment of the present disclosure are similar to the execution method of step S31 and step S33 in FIG6 , and are not described in detail here.

In step S52, when the reporting judgment conditions are met, configuration indication information is sent so that the network device configures the CG PUSCH configuration used for CG PUSCH transmission for the terminal based on the configuration indication information.

For ease of understanding, three reporting judgment conditions that can be used to trigger the sending of configuration indication information are exemplified below.

Judgment condition 1: The layer 1 interference plus noise ratio (L1-SINR) obtained by beam measurement or the interference plus noise ratio (SINR) obtained by other measurements is compared with the SINR threshold.

Judgment condition 2: Whether the estimated value of the reference signal received power (RSRP) meets the RSRP estimated value threshold that makes the terminal located at the edge of the cell.

Judgment condition 3: Compare the channel quality indicator (CQI) of the specified layer obtained by using the downlink signal to estimate the channel state information with the CQI threshold value, or compare the signal with the SINR with the SINR threshold value.

Judgment condition 4: whether the probability of continuous data transmission errors and/or the probability of retransmission failure under the specified number of transmission layers increases and reaches a specified threshold.

Wherein, for judgment condition 1, if L1-SINR or SINR is higher than the SINR threshold, the CP-OFDM waveform is used. Correspondingly, if L1-SINR or SINR is lower than or equal to the SINR threshold, the DFTS-OFDM waveform is used.

For judgment condition 2, if the RSRP estimation value of the reference signal received power satisfies the RSRP estimation value threshold that places the terminal at the edge of the cell, then CG PUSCH transmission using the DTFS-OFDM waveform can ensure a better communication effect. At this time, the terminal can determine the DTFS-OFDM waveform as the waveform used for CG PUSCH transmission, and in the CG PUSCH configuration corresponding to the DTFS-OFDM waveform, determine the CG PUSCH configuration used for CG PUSCH transmission, and then send the configuration indication information. Correspondingly, if the RSRP estimation value of the reference signal received power does not meet the RSRP estimation value threshold that places the terminal at the edge of the cell, then CG PUSCH transmission using the CP-OFDM waveform can ensure a better communication effect. In this case, the method of sending the configuration indication information is similar to the relevant embodiments involving the above-mentioned DTFS-OFDM waveform, and will not be repeated here. In addition, for judgment condition 2, the RSRP estimation value threshold is used to determine whether the terminal is located at the edge of the cell, and can be set accordingly according to actual needs. The present disclosure does not limit the specific value of the RSRP estimation value threshold.

For judgment condition 3, the cyclic prefix orthogonal frequency division multiplexing CP-OFDM waveform is used to estimate the channel state information, which is used to determine the communication quality of CG PUSCH transmission using the CP-OFDM waveform. If it is determined that the channel quality CQI of the specified number of layers is lower than the CQI threshold value or the signal to interference plus noise ratio SINR is lower than the SINR threshold value, it means that the communication effect of CG PUSCH transmission using the CP-OFDM waveform is poor. At this time, the terminal can determine the DTFS-OFDM waveform as the waveform used for CG PUSCH transmission, and determine the CG PUSCH configuration used for CG PUSCH transmission in the CG PUSCH configuration corresponding to the DTFS-OFDM waveform, and then send the configuration indication information. Correspondingly, if it is determined that the CQI of the specified number of layers is higher than the CQI threshold value and/or the signal and SINR are higher than the SINR threshold value, then the CP-OFDM waveform is used to transmit CG PUSCH to ensure a better communication effect. In this case, the method of sending the configuration indication information is similar to the relevant embodiments involving the above-mentioned DTFS-OFDM waveform, and will not be repeated here.

For judgment condition 4, the terminal performs CG PUSCH transmission according to any transmission waveform of the CP-OFDM waveform and the DTFS-OFDM waveform. If the terminal has an increase in the probability of continuous data transmission error and/or retransmission failure under the specified number of transmission layers, it means that the transmission waveform currently used by the terminal cannot guarantee a better communication effect. Take the case where the terminal performs CG PUSCH transmission according to the CP-OFDM waveform, and the probability of continuous data transmission error and/or retransmission failure increases. In this case, the terminal can determine the DTFS-OFDM waveform as the waveform used for CG PUSCH transmission, and determine the CG PUSCH configuration used for CG PUSCH transmission in the CG PUSCH configuration corresponding to the DTFS-OFDM waveform, and then send the configuration indication information. Correspondingly, if the terminal performs CG PUSCH transmission according to the DFTS-OFDM waveform, and the probability of continuous data transmission error and/or retransmission failure increases, then the CP-OFDM waveform can guarantee a better communication effect for CG PUSCH transmission. In this case, the method of sending the configuration indication information is similar to the relevant embodiments involving the above-mentioned DTFS-OFDM waveform.

For the three judgment conditions involved in the above embodiment, the terminal can send configuration indication information when determining that at least one of the above reporting judgment conditions is met. In addition, it should be noted that the configuration indication information can also be sent through other judgment conditions, and the configuration method of the judgment condition is not limited to this.

Usually, there is a certain correlation between the service and the CG PUSCH configuration. For example, in the related art, the service feature words, arrival models, and requirements for latency and reliability of different services are not the same. Therefore, the transmission parameters corresponding to the CG PUSCH configurations configured for different services are usually different, and the waveform is currently configured through semi-static RRC. Through the uplink waveform configuration method provided by the embodiment of the present disclosure, when configuring the transmission waveform, for the CG PUSCH configuration corresponding to a specific service in different services, the configured transmission waveform can be further configured to have waveform differences. For example, in order to support dynamic waveform selection, the service corresponding to the CG PUSCH can simultaneously configure two sets of CG PUSCH configurations _A1 and _B1 with different waveforms. On this basis, CG PUSCH configuration _A1 can be configured with a transmission waveform _W1 , and CG PUSCH configuration _B1 can be configured with a transmission waveform _W2 . Compared with the two, the configured transmission waveforms can be different. The waveform selections actually corresponding to different services can also be different.

In addition, in the related art, when comparing multiple CG PUSCH configurations corresponding to the same service, the configured transmission waveforms are usually the same fixed waveform. In this regard, through the uplink waveform configuration method provided by the embodiment of the present disclosure, different transmission waveforms can be configured for multiple CG PUSCH configurations corresponding to the same service, and then while the terminal supports the service, the transmission waveform can be switched by switching the CG PUSCH configuration, so as to realize dynamic configuration of the transmission waveform while supporting the service. Furthermore, for the solution in which the terminal side autonomously selects the CG PUSCH configuration used for CG PUSCH transmission, if it is determined that the transmission waveform used for CG PUSCH transmission corresponds to multiple CG PUSCH configurations, it is necessary to further screen among the multiple CG PUSCH configurations corresponding to the transmission waveform to determine the CG PUSCH configuration used by the terminal for CG PUSCH transmission.

As a feasible implementation method, in order to better support the "come and go" of data packets for the same service configuration and minimize the transmission delay, the network introduces the "flexible trigger execution CG PUSCH transmission" mechanism. The network can configure multiple sets of CG PUSCH configurations for the same service. These CG PUSCH configurations usually have the same transmission period, transmission opportunity size, number of repeated transmissions, and MCS, etc. Different CG PUSCH configurations are staggered at different transmission opportunities for terminal selection. The current protocol supports semi-static RRC configuration transmission waveforms. In order to support more dynamic waveform configuration and switching, the number of CG PUSCH configurations can be increased at the same time, and multiple sets of CG PUSCH configurations can be configured for different transmission waveforms. Among them, the screening process can be achieved by enhancing the "flexible start" mechanism and "switch" control involved in the multi-configuration scheme. Among them, the "flexible start" mechanism means that a CG PUSCH configuration has multiple transmission opportunities, and different transmission opportunities are distributed along the timing. The terminal can select any transmission opportunity for CG PUSCH transmission. "Switch" control means that each CG PUSCH configuration is equipped with a control switch that can be switched between the "on" position and the "off" position. The terminal can trigger the switch according to actual needs to select different transmission opportunities distributed along the timing. On this basis, the terminal can determine the nearest transmission opportunity among multiple CG PUSCH configurations corresponding to the transmission waveform used for CG PUSCH transmission according to the "flexible start" mechanism and "switch" control, and then use the CG PUSCH configuration with the nearest transmission opportunity as the CG PUSCH configuration used for CG PUSCH transmission, so as to ensure the timeliness of CG PUSCH transmission.

In the uplink waveform configuration method provided by the embodiment of the present disclosure, the terminal can determine the CG PUSCH configuration used for CG PUSCH transmission according to the transmission waveform used for CG PUSCH transmission, and then send configuration indication information. On this basis, the network device can determine the CG PUSCH configuration that the terminal expects to use based on the configuration indication information, and use this as the CG PUSCH configuration used by the terminal configuration for CG PUSCH transmission. This method provides an implementation scheme for the terminal side to autonomously determine the CG PUSCH configuration to be used.

Correspondingly, the CG PUSCH configuration used by the terminal for CG PUSCH transmission can be determined not only autonomously by the terminal side, but also by the network device side.

As a feasible implementation method, the network device can determine the CG PUSCH configuration used by the terminal for CG PUSCH transmission, and then activate the terminal to use the determined CG PUSCH configuration for CG PUSCH transmission by sending configuration activation information. The configuration activation information is used to activate the CG PUSCH configuration corresponding to the transmission waveform used for CG PUSCH transmission.

FIG9 is a flow chart of another uplink waveform configuration method according to an exemplary embodiment. As shown in FIG9 , step S61 and step S63 in the embodiment of the present disclosure are similar to the execution method of step S21 and step S22 in FIG5 , and are not described in detail here.

In step S62, configuration activation information sent by the network device is received.

For example, the configuration activation information can be carried in the downlink control information signaling (Downlink Control Information, DCI).

Further, as a feasible implementation, the configuration activation information can be carried in the hybrid automatic repeat request (HARQ) process number field of the DCI. The HARQ process number field includes an HPN value, which is used to indicate the HARQ process number and to indicate the CG PUSCH configuration corresponding to the transmission waveform used for CG PUSCH transmission.

Generally, CG PUSCH includes CG PUSCH with configuration authorization type 1 (type 1) and CG PUSCH with configuration authorization type 2 (type 2) (hereinafter, for the convenience of description, the present disclosure will refer to configuration authorization type 1 as the first authorization type and configuration authorization type 2 as the second authorization type). For the convenience of understanding, configuration authorization type 1 and configuration authorization type 2 are explained below respectively.

Configure grant type 1, and the uplink grant is provided by RRC signaling, for example, including the activation of the grant. Once the terminal correctly receives the configuration of the RRC signaling, it takes effect immediately. Among them, the transmission parameters configured by RRC signaling may include, for example, the period, time offset and frequency resources, and the modulation and coding method used by PUSCH. After receiving the RRC configuration, the terminal starts to transmit using the configured grant at the time given by the period and offset. The offset is to control at which time the terminal is allowed to transmit.

Configure authorization type 2, and the transmission cycle is provided by RRC signaling. The network equipment realizes resource activation and configuration of some transmission parameters through DCI signaling, thereby realizing the activation transmission of the authorization configuration. After the terminal receives the activation command, if there is data to be sent in the cache, it will be transmitted according to the pre-configured cycle. If there is no data, the terminal will not transmit any data. The activation time is specified by the sending time of the Physical Downlink Control Channel (PDCCH). The terminal can choose to activate the configuration authorization type 2 or deactivate the configuration authorization type 2 by sending MAC control signaling in the uplink.

In the above-mentioned embodiment, for the scheme in which the terminal side autonomously determines the CG PUSCH configuration used for CG PUSCH transmission, the terminal can determine the CG PUSCH configuration used for CG PUSCH transmission based on the transmission waveform used for CG PUSCH transmission, and then send the configuration indication information. On this basis, the network device can determine the CG PUSCH configuration that the terminal expects to use based on the configuration indication information, and configure the CG PUSCH configuration used for CG PUSCH transmission for the terminal based on this. For the scheme in which the terminal side autonomously determines the CG PUSCH configuration used for CG PUSCH transmission, since the scheme directly executes the configuration and activation of the corresponding CG PUSCH configuration through the network device, the scheme implementation can be adapted to the CG PUSCH of the first authorization type.

Correspondingly, since the network device side determines the scheme of the CG PUSCH configuration used for CG PUSCH transmission, the network device can directly activate the CG PUSCH configuration used for CG PUSCH transmission on the terminal side by sending configuration activation information (for example, it can be DCI signaling). Therefore, the scheme implementation can be adapted to the second authorization type of CG PUSCH.

The uplink waveform configuration method provided by the embodiment of the present disclosure provides an adaptable uplink waveform configuration scheme for CG PUSCH with a first authorization type and CG PUSCH with a second authorization type, respectively.

In the related art, since the transmission waveform corresponding to the CG PUSCH configuration is single, the maximum number of CG PUSCH configurations that are allowed to be configured for each bandwidth part (Bandwidth Part, BWP) is only 12. Among them, the CG PUSCH configurations configured for each partial bandwidth BWP can all be CG PUSCH configurations of the first authorization type, all be CG PUSCH configurations of the second authorization type, or include both the CG PUSCH configuration of the first authorization type and the CG PUSCH configuration of the second authorization type. Due to the uplink waveform configuration method provided in the embodiment of the present disclosure, the transmission waveform needs to be configured differentially. Therefore, it is necessary to further expand the threshold value of the number of CG PUSCH configurations that can be configured for the partial bandwidth BWP.

In a feasible implementation, multiple groups of CG PUSCH configurations can be configured by the same partial bandwidth BWP, and the CG PUSCH configuration quantity threshold that the partial bandwidth BWP is allowed to configure is the CG PUSCH configuration quantity threshold after quantity expansion. The CG PUSCH configuration quantity threshold after quantity expansion is used to ensure that the terminal supports the service normally and realizes the differentiated configuration of different CG PUSCH configurations for the transmission waveform.

For example, after the CG PUSCH configuration quantity threshold that is allowed to be configured for a portion of the bandwidth BWP is expanded, the CG PUSCH configuration quantity threshold after the expansion should be greater than 12, including 18 or 24. Among them, taking 24 as an example, when the CG PUSCH configuration quantity threshold is 12, it can meet the demand of supporting CG PUSCH transmission with a single transmission waveform. The CG PUSCH configuration quantity threshold is further expanded to 24 to support another transmission waveform (for example, DFTS-OFDM) in addition to the above single transmission waveform (for example, CP-OFDM), so as to support CG PUSCH transmission through any one of the two transmission waveforms. In addition, considering that the number of CG PUSCHs corresponding to the two transmission waveforms does not need to be completely consistent, therefore, configuring the CG PUSCH configuration quantity threshold to 18 can actually meet the usage requirements.

The uplink waveform configuration method provided by the disclosed implementation can update the transmission waveform corresponding to the CG PUSCH configuration of the first authorization type included in multiple groups of CG PUSCH configurations. For example, the transmission waveform corresponding to the CG PUSCH configuration of the first authorization type included in the updated multiple groups of CG PUSCH configurations can be used as the transmission waveform used for CG PUSCH transmission.

In one implementation, the terminal may update the transmission waveform corresponding to the CG PUSCH configuration according to the waveform indication information. For example, when the terminal receives the waveform indication information, it determines the waveform indicated by the waveform indication information, that is, the transmission waveform used for the CG PUSCH transmission. On this basis, the terminal may update the transmission waveform corresponding to the CG PUSCH configuration of the first authorization type according to the transmission waveform used for the CG PUSCH transmission.

In another implementation, the terminal may update the transmission waveform corresponding to the CG PUSCH configuration according to the configuration activation information. For example, when receiving the configuration activation information, the terminal determines the CG PUSCH configuration activated by the configuration activation information, and then updates the transmission waveform corresponding to the CG PUSCH configuration of the first authorization type according to the transmission waveform corresponding to the activated CG PUSCH configuration.

Based on the same concept, an embodiment of the present disclosure also provides an uplink waveform configuration method applied to a network device.

The network device involved in this embodiment is used to interact with the terminal involved in any of the above embodiments to complete the configuration of the transmission waveform actually used by the terminal. If there is any unclear point in the following embodiment, refer to any of the above embodiments. Similarly, if there is any unclear point in the above embodiment, refer to any of the following embodiments.

FIG. 10 is a flow chart of an uplink waveform configuration method according to an exemplary embodiment. As shown in FIG. 10 , the method is used in a network device and includes the following steps.

In step S71, PUSCH configuration information is provided for the terminal CG.

Among them, the CG PUSCH configuration information is used to configure multiple groups of CG PUSCH configurations, and the transmission waveforms corresponding to the multiple groups of CG PUSCH configurations include at least two different transmission waveforms, and each transmission waveform corresponds to one or more groups of CG PUSCH configurations.

In the uplink waveform configuration method provided by the embodiment of the present disclosure, the network device can provide the terminal with CG PUSCH configuration information for configuring multiple groups of CG PUSCH configurations, and the multiple groups of CG PUSCH configurations correspond to at least two different transmission waveforms. On this basis, the terminal selects the CG PUSCH configuration corresponding to different transmission waveforms to achieve the switching of the transmission waveform. Compared with the semi-static configuration method using RRC signaling in the related art, this method has better flexibility and realizes the dynamic configuration of the transmission waveform.

For example, a network device may be used to configure a CG PUSCH configuration used by a terminal for CG PUSCH transmission.

FIG11 is a flow chart of another uplink waveform configuration method according to an exemplary embodiment. As shown in FIG11 , step S81 in the embodiment of the present disclosure is similar to the execution method of step S11 in FIG10 , and will not be described in detail herein.

In step S82, configuration indication information sent by the terminal is received.

Among them, the configuration indication information is used to indicate the CG PUSCH configuration used for CG PUSCH transmission;

In step S83, based on the configuration indication information, the CG PUSCH configuration used for CG PUSCH transmission is configured for the terminal.

For example, the configuration indication information received by the network device may be sent by the terminal according to the waveform indication information after the waveform indication information is sent to the terminal.

FIG12 is a flowchart of another uplink waveform configuration method according to an exemplary embodiment. As shown in FIG12 , step S91, step S93, and step S94 in the embodiment of the present disclosure are similar to the execution method of step S81, step S82, and step S83 in FIG11 , and are not described in detail here.

In step S92, waveform indication information is sent to the terminal, so that the terminal sends configuration indication information when receiving the waveform indication information.

Among them, the waveform indication information is used to indicate the transmitting waveform used by the terminal for CG PUSCH transmission.

The waveform indication information is carried in the media access control MAC control element CE signaling and/or the downlink control information DCI signaling.

In the uplink waveform configuration method provided by the embodiment of the present disclosure, the network device can, for example, receive the configuration indication information sent by the terminal when the reporting judgment condition is met.

Among them, the reporting judgment conditions include at least one of the following:

In the above-mentioned embodiments, for the scheme in which the terminal side autonomously determines the CG PUSCH configuration used for CG PUSCH transmission, the terminal can determine the CG PUSCH configuration used for CG PUSCH transmission based on the transmission waveform used for CG PUSCH transmission, and then send the configuration indication information. On this basis, the network device can determine the CG PUSCH configuration that the terminal expects to use based on the configuration indication information, and configure the CG PUSCH configuration used for CG PUSCH transmission for the terminal based on this. In the above-mentioned embodiments, for the scheme in which the terminal side autonomously determines the CG PUSCH configuration used for CG PUSCH transmission, since the scheme directly executes the configuration and activation of the corresponding CG PUSCH configuration through the network device, the scheme implementation can be adapted to the CG PUSCH of the first authorization type.

In the uplink waveform configuration method provided by the embodiment of the present disclosure, a network device can send configuration activation information to a terminal. The configuration activation information is used to activate the CG PUSCH configuration corresponding to the transmission waveform used for CG PUSCH transmission.

In the disclosed embodiment, the configuration activation information is carried in the DCI.

For example, the configuration activation information is carried in the hybrid automatic repeat request HARQ process number field of the DCI; wherein the HARQ process number field includes an HPN value, the HPN value is used to indicate the HARQ process number, and is used to indicate the CG PUSCH configuration corresponding to the transmission waveform used for CG PUSCH transmission.

In the above embodiment, since the network device side determines the scheme of the CG PUSCH configuration used for CG PUSCH transmission, the network device can directly activate the CG PUSCH configuration used for CG PUSCH transmission on the terminal side by sending configuration activation information (for example, it can be DCI signaling). Therefore, the scheme implementation can be adapted to the second authorization type of CG PUSCH.

For example, after the CG PUSCH configuration quantity threshold for which partial bandwidth BWP is allowed to be configured is expanded, the expanded CG PUSCH configuration quantity threshold should be greater than 12, including 18 or 24.

In the above embodiments, on the one hand, for the scheme in which the terminal side autonomously determines the CG PUSCH configuration used for CG PUSCH transmission, the terminal can determine the CG PUSCH configuration used for CG PUSCH transmission based on the transmission waveform used for CG PUSCH transmission, and then send the configuration indication information. On this basis, the network device can determine the CG PUSCH configuration that the terminal expects to use based on the configuration indication information, and configure the CG PUSCH configuration used for CG PUSCH transmission for the terminal on this basis. On the other hand, since the network device side determines the scheme in which the CG PUSCH configuration used for CG PUSCH transmission is used, the network device can directly activate the CG PUSCH configuration used for CG PUSCH transmission on the terminal side by sending configuration activation information (for example, DCI signaling). On this basis, in the process of interaction between the terminal and the network device, by selecting or activating different CG PUSCH configurations, the dynamic switching of the transmission waveform used for CG PUSCH transmission of the terminal can be realized, thereby improving the flexibility of the terminal in CG PUSCH transmission.

The method provided in the embodiment of the present disclosure has made further improvements on the basis of the enhanced multi-configuration scheme in the related art, so as to realize the dynamic configuration of the transmission waveform of the CG PUSCH transmission. Among them, the CG PUSCH configuration used by the terminal for CG PUSCH transmission can be determined by the network device, or by the terminal itself. In addition, when determining the CG PUSCH configuration used, the transmission waveform referenced by the terminal can also be determined by the network device side and notified to the terminal, or determined autonomously by the terminal side. On this basis, for the two types included in CG PUSCH (i.e., configuration authorization type 1 and configuration authorization type 2), the present disclosure provides corresponding adaptation schemes respectively. In addition, the present disclosure provides more flexible configuration options for multiple CG PUSCH configurations corresponding to the same service, and CG PUSCH configurations corresponding to different services. Furthermore, in order to make the number of CG PUSCH configurations that are allowed to be configured for a partial bandwidth BWP meet the differentiated configuration requirements for the transmission waveform, the present disclosure further expands the threshold value of the number of CG PUSCH configurations that can be configured for a partial bandwidth BWP. In addition, in order to meet the update of the transmission waveform corresponding to the configured CG PUSCH configuration, the present disclosure also proposes an adaptation scheme for updating the transmission waveform corresponding to the CG PUSCH configuration of the second authorization type by configuring activation information or waveform indication information, so as to improve each link of the dynamic configuration of the transmission waveform.
