Method performed by user equipment and user equipment

Technical Field

The present invention relates to the field of wireless communication technology, and in particular, to a method performed by a user equipment and a corresponding user equipment.

Background

This section introduction may facilitate a better understanding of various aspects of the disclosure. The statements in this section are thus to be read in this light, and not as admissions of what is or is not prior art.

Several typical applications are defined in 5G systems, such as industrial wireless sensor applications, which are aimed at speeding up industrial transmission and digitization for flexibility, productivity and efficiency, as well as for reducing maintenance, improving operational safety, etc. The video monitoring equipment is applied to intelligent city construction, and better city management and service are realized. Wearable devices may be used for intelligent services in a number of aspects of medicine, life, etc. User equipment for these applications both desire lower complexity and less power consumption. To better implement these applications, the market for related devices is expanded, with further consideration being given to reducing their complexity. For example, reducing the peak data rate of these devices to a maximum of 10Mbps, limiting the user device bandwidth to 5MHz, and possibly relaxing some of the processing time constraints of the data channel. At the same time, the coexistence of these devices with existing capacity-reducing devices and other NR user devices in the same cell must be considered to maintain the integrity of the ecology of the existing devices and maximize the ecological scale. These services put some new demands on existing NR networks. For example, a network to support a reduction in bandwidth of user equipment to a maximum of 5MHz requires that the network configuration or data transmission procedures meet the relevant requirements. The peak rate of the user equipment to be reduced also requires some new constraints for data scheduling of the network, etc. The related method provides a better method for realizing the capacity reduction requirement of the devices in the network, ensures the coexistence requirement of the devices in the network with the existing devices, and obtains better network utilization efficiency.

The following is a description of the technology associated with the scheme of the present invention. Unless otherwise indicated, the same terms in the specific examples have the same meaning as those in the related art.

It should be noted that, in the description of the present invention, the user equipment and the terminal equipment refer to the same meaning, and the UE may also be used to denote the user equipment, which is not specifically distinguished and limited hereinafter. Similarly, the network device is a device that communicates with the user equipment, including but not limited to a base station device, a gNB, an eNB, a wireless AP, a wireless relay, a relay-capable terminal, and the like, and is not specifically distinguished and limited hereinafter. The description herein may be made in terms of one form of base station implemented as a network device, and other forms of network device may be readily substituted for the specific implementation.

When the user equipment performs communication service in the NR network, it is required to receive a system message sent by the network. For example, the user equipment searches for and receives SSB signals on a frequency band and receives system broadcast information according to configuration information therein. The SSB includes three signals or channels, i.e., PSS, SSS, and PBCH, for respectively transmitting different system information. In the NR system, the SSB signal occupies a total of 4 symbols and 20 RBs of time-frequency resources. When the SSB is transmitted using the 15KHz subcarrier parameter, the bandwidth occupied by the SSB is at least 3.6MHz. When the SSB is transmitted using the 30KHz subcarrier parameter, the bandwidth occupied by the SSB is 7.2MHz.

Upon receiving the valid SSB signal, the user equipment may obtain MIB information transmitted by the PBCH or the like according to the SSB signal. The user equipment can determine the parameters of the bandwidth, the number of symbols, the frequency domain position and the like of CORESET used by PDCCH for scheduling PDSCH resources carrying SIB1 according to MIB information, namely the type0-PDCCH CSS parameters. For example, the information transmitted by the PBCH channel includes MIB information and some other system configuration information. The user equipment may determine SCS parameters used for SIB1/PDCCH according to the subclrierspacengcommon in MIB message. The user equipment may detect PDCCH in type0 PDCCH CSS, and the obtained DCI information, i.e., scheduling information of the related PDSCH.

There are many possible implementations of limiting the maximum bandwidth of the user equipment to 5MHz or limiting the peak rate of the user equipment. For example, the maximum bandwidth of the control channel received by the user equipment may be limited to 20MHz and the maximum bandwidth of the data channel may be limited to 5MHz. This may enable the user equipment to receive control channel information transmitted in a 20MHz bandwidth and determine scheduling information of PDSCH according to DCI indication in the control channel. Meanwhile, the user equipment limits the data channel to use the bandwidth not more than 5MHz, so that the complexity of the user equipment can be reduced, and related targets are realized. Alternatively, the user equipment limits the number of RBs used by the processed data channel to be no greater than a predetermined value, which can also reduce the complexity of the user equipment receiving or transmitting device. Or there are other methods such as limiting the maximum transport block size for the user equipment to process data, relaxing the minimum limit for the maximum MIMO layer number multiplied by the modulation order and the scaling factor, relaxing the time requirements for the user equipment to process each traffic channel or signal, etc. A combination of one or more of the above methods may be used in a network to achieve the relevant objective.

For a specific example, to ensure that the capability of the user equipment is not exceeded when transmitting the data channel PDSCH/PUSCH, the network schedules PDSCH for transmission using a continuous bandwidth of no more than 5MHz and determines the relevant parameters based on the SCS parameters used for PDSCH transmission. For example, when PDSCH is transmitted using SCS of 15kHz, resources are allocated on BWP with a bandwidth of not more than 25 RBs, such that the transmission bandwidth of PDSCH does not exceed 5MHz. Alternatively, frequency hopping is used over a larger bandwidth BWP in such a way that the total bandwidth of the resources allocated to the user equipment over any symbol does not exceed 5MHz. PDSCH is transmitted, for example, on BWP of 20MHz total bandwidth, and when the BWP uses SCS of 15kHz, the total number of available RBs within 20MHz bandwidth is 106. When the network uses several symbols for PDSCH transmission over this bandwidth, the first half of the symbols are transmitted using 24 RBs and the second half of the symbols are transmitted using another 24 RBs. The RBs of the two parts may be distributed over different bandwidths within the total bandwidth. But the total bandwidth received by the user equipment on any symbol still does not exceed 25 RBs. Or, the method of using scheduling limitation on the BWP with larger bandwidth is such that the total bandwidth of the resources allocated to the user equipment on any symbol is not more than 5MHz, when SCS is 15kHz, the method of using non-interleaving mapping when mapping from VRB to PRB can be implemented by downlink scheduling to allocate resources of not more than 25 RBs. Other methods may be used in the network such that the data transmission does not exceed the capability limits of the user equipment, as is not limited herein. Similarly, these methods may also be applied to the transmission of the uplink data channel, and will not be described in detail here.

In the invention, the network uses a proper indication method, so that the user equipment with limited capability can coexist with other user equipment in the same cell, and related data transmission can meet the requirements of the user equipment, thereby realizing the service requirement.

The network may also relax the processing time constraints of the ue so that the ue may have more processing time when receiving or transmitting data, thereby reducing the complexity of the associated device. There may be some problems when this type of user equipment co-exists with other types of user equipment in the network. For example, the time parameter of network scheduling does not meet the requirement of the user equipment, and the related embodiments of the present invention solve the problems, so that the user equipment and the network can obtain consistent understanding, and ensure the normal operation of the communication service.

Embodiments of the present invention will be specifically described below. Hereinafter, unless explicitly stated, the user equipments refer to such user equipments using smaller data transmission bandwidths to reduce complexity.

[ example 1 ]

In the method performed by the ue in embodiment 1 of the present invention, the ue determines whether the network supports access and/or data transmission usage parameters of the ue using a smaller data transmission bandwidth according to the indication information, where the number of RBs of the bandwidth used for the downlink shared channel PDSCH or the uplink shared channel PUSCH is not greater than a predetermined value.

Fig. 1 is a flow chart of a method performed by a user equipment according to embodiment 1 of the present invention.

As shown in fig. 1, in step S101, the user equipment receives a synchronization signal/physical broadcast channel block SSB signal and obtains type0-PDCCH CSS related parameters.

In step S102, the user equipment detects the PDCCH according to the type0 PDCCH CSS, and obtains indication information.

In step S103, the ue can determine that the network supports access of the ue according to the indication information, and/or the ue determines parameters used for data transmission according to the indication information.

The related processes are described in detail below.

In the NR system, the user equipment detects PDCCH in a type0-PDCCH CSS to obtain scheduling DCI information. The user equipment receiving SSB may obtain type0-PDCCH CSS related parameters, e.g., the user equipment may determine the configuration information of CORESET associated with type0-PDCCH CSS, i.e., the configuration information of CORESET 0. Typically, the frequency domain resource of CORESET0 may use one of 24RB or 48RB or 96RB when SCS of bandwidth is 15kHz and one of 24RB or 48RB when SCS is 30 kHz. In all cases, except for the 24RB/15kHz configuration, the CORESET0 bandwidth exceeds 5MHz. In the NR network, before the ue obtains specific radio link configuration information, the channel bandwidth of PDSCH scheduling in some common procedures is distributed in the bandwidth range determined by CORESET0, which is determined by the DCI frequency domain indicator for scheduling the PDSCH. At this time, if the bandwidth of CORESET0 is greater than 5MHz, the bandwidth used by the scheduled PDSCH may be greater than 5MHz, exceeding the capabilities of some user devices. For example, PDSCH scheduled by DCI using P-RNTI scrambling CRC in paging phase, PDSCH scheduled by DCI using RA-RNTI scrambling CRC in random access phase, PDSCH scheduled by DCI using SI-RNTI scrambling CRC, PDSCH scheduled by DCI using TC-RNTI scrambling CRC, or the like may use CORESET0 as a reference to determine the relevant scheduling bandwidth. At this time, the ue may not correctly receive the related information, and thus may not perform the related network service. On the other hand, as the dynamic scheduling method is used for scheduling the PDSCH in the network, the PDSCH which is scheduled at different time can use different resources for transmission, the bandwidth which is possibly used at some time is not more than 5MHz, and the bandwidth which is used at other time is more than 5MHz, so that the performance of the user equipment for receiving the network information is unstable, and the service performance is influenced. In addition, in the random access process, the user equipment receives the random access response RAR message and includes uplink authorization for determining the resource used by the user equipment for sending msg 3. The bandwidth of the resource is associated with the bandwidth of the initial upstream BWP of the cell configuration and may also be out of the capability of the user equipment.

In an alternative embodiment, the ue determines whether the network supports access of the ue according to the received indication information of the network, or the ue determines a method or parameter of access of the ue supported by the network. One specific example is shown in table 1, where the ue determines different support modes of the network for the ue according to the 2-bit indication information. For example, the bit indication received by the ue is 00, the ue determines the indication information to be a reserved bit, and the network does not support access of the ue using a specific method or configuration. At this point, if the user equipment receives or transmits a data channel in the network, the bandwidth capability of the user equipment may be exceeded. When the bit indication received by the user equipment is not 00, a specific method or configuration or parameter is used in the network to support the data transmission of the user equipment. For example, according to the network indication, the user equipment determines that the PDSCH parameters scheduled by DCI using a specific RNTI scrambling CRC always satisfy a specific assumption, such as that its bandwidth is always smaller than a predefined value. In this way, the user equipment meeting the relevant receiving capability determines that relevant PDSCH data transmission can be received in the network according to the information, and relevant service functions are realized.

01	Mode 1

Optionally, the user equipment determines, according to the indication information, a parameter value of PDSCH scheduled by DCI using some RNTI scrambling CRC.

For example, when the network allocates PDSCH resources to the user equipment using downlink resource allocation type 1, the DCI indicates a segment of allocated frequency-domain continuous resources using RIV as the frequency-domain resource indication information. Specifically, an RIV value can be calculated according to the following method based on the starting position RBstart of the allocated resources in the frequency domain and the number of RBs used by the allocated bandwidth.

The user equipment may obtain a starting position and a frequency domain width of the scheduled resource on the BWP bandwidth according to the RIV value in the DCI, and perform PDSCH reception on the related resource.

It is also possible to use an interleaved or non-interleaved manner in mapping VRBs to PRBs in the network when PDSCH data is transmitted, that is, mapping the sequence numbers of VRBs indicated by DCI to the sequence numbers of actual physical resource PRBs according to a certain rule. When the non-interleaving is used, the mapping is carried out according to interleaving parameters, and after the mapping, continuous RBs on the VRB correspond to discontinuous PRBs, so that the bandwidth occupied by all PRBs is increased.

Alternatively, when the indication information is mode 1, the user equipment determines that the number of RBs of the bandwidth used by PDSCH resources scheduled using DCI of SI-RNTI or P-RNTI or TC-RNTI or RA-RNTI scrambling CRC does not exceed a specific value, which is determined by SCS used by the data channel. The user equipment expects the VRB-to-PRB mapping threshold in these DCIs to be 0, i.e. the scheduled PDSCH uses non-interleaving mode for VRB-to-PRB mapping.

Alternatively, when the indication information is mode 2, the user equipment determines that the total number of RBs used by PDSCH resources scheduled using DCI of SI-RNTI or P-RNTI or TC-RNTI or RA-RNTI scrambling CRC does not exceed a specific value, which is determined by SCS used by the data channel.

Optionally, the user equipment further determines a parameter for the user equipment to receive the PDSCH channel according to the second indication information in the DCI. For example, when the ue determines that the indication information is in mode 3, the ue determines, according to the second indication information in the DCI, the location and bandwidth of the specific initial downlink BWP or CORESET for the ue to receive data. For example, the second indication information includes an offset value of RB0 with respect to CORESET where the current PDCCH is located. The user equipment may determine the starting position of a particular initial downlink BWP or CORESET based on the offset. The user equipment determines the bandwidth of the specific initial downlink BWP or CORESET according to the predetermined value or the bandwidth value in the second indication information. The user equipment can also determine the number of symbols and the symbol position used by the user equipment for searching the PDCCH on the specific CORESET according to the preset value or the same number of symbols and the symbol position used by the CORESET where the current PDCCH is located or the number of symbols and the symbol position in the second indication information. The user equipment may search for PDCCH on a specific CORESET according to the indicated information to obtain relevant scheduling information.

Optionally, the user equipment further determines parameters for the user equipment to receive the PDSCH channel according to the third indication information in the SIB. For example, when the indication information is mode 1, the user equipment determines that the number of RBs of the bandwidth used by PDSCH resources scheduled by DCI using SI-RNTI scrambling CRC does not exceed a specific value, which is determined by SCS used by the data channel. The user equipment expects the VRB-to-PRB mapping field in these DCIs to be 0, i.e. the scheduled PDSCH uses non-interleaving mode for VRB-to-PRB mapping. At this time, the user equipment may receive SIB information on PDSCH scheduled by DCI format 1_0 of the SI-RNTI scrambling CRC. The SIB information includes configuration information of a specific initial downlink BWP, and is used for receiving PDSCH scheduled by DCI of TC-RNTI or RA-RNTI scrambling CRC by the user equipment.

Alternatively, the specific value used by the bandwidth RB determined by the SCS of the data channel may be implemented in a predefined manner, for example, the number of RBs determined when the SCS is 15kHz is 25, and the number of RBs determined when the SCS is 30kHz is 11. Or the number of RBs determined when SCS is 15kHz is 24, and the number of RBs determined when SCS is 30kHz is 12.

Optionally, the user equipment determines, according to the indication information, a parameter of a PUSCH scheduled by DCI using TC-RNTI scrambling CRC or a PUSCH scheduled by uplink grant in the RAR message.

Optionally, when the indication information is mode 1, the user equipment determines that the number of RBs of the bandwidth used by DCI using TC-RNTI scrambling CRC or PUSCH resources scheduled by uplink grant in the RAR message does not exceed a value determined by SCS used by the data channel. And the user equipment expects the frequency domain hopping indication value in the relevant DCI or uplink grant to be 0, that is, the scheduled PUSCH does not use frequency hopping.

Optionally, when the indication information is mode 2, the user equipment determines that the number of RBs of the bandwidth used by DCI using TC-RNTI scrambling CRC or PUSCH resources scheduled by uplink grant in the RAR message does not exceed a value determined by SCS used by the data channel.

Optionally, the user equipment further determines a parameter for the user equipment to transmit the PUSCH channel according to the fourth indication information in the SIB. For example, when the indication information is mode 1, the user equipment determines that the number of RBs of the bandwidth used by PDSCH resources scheduled by DCI using SI-RNTI scrambling CRC does not exceed a specific value, which is determined by SCS used by the data channel. The user equipment expects the VRB-to-PRB mapping field in these DCIs to be 0, i.e. the scheduled PDSCH uses non-interleaving mode for VRB-to-PRB mapping. At this time, the user equipment may receive SIB information on PDSCH scheduled by DCI format 1_0 of the SI-RNTI scrambling CRC. The SIB information contains configuration information of a specific initial uplink BWP, and is used for transmitting a PUSCH scheduled by uplink grant in DCI or RAR message of TC-RNTI scrambling CRC by the user equipment.

It is also possible to use more or fewer bits in the network to carry the indication information. For example, 1 bit is used to indicate the relevant information. The ue determines the relevant data channel transmission parameters by using the method defined in mode 1 above when the bit indication is 1, and retains the information when the bit indication is 0. The relevant methods in the above examples may still be utilized in combination and will not be described here again.

The user equipment needs to acquire the related indication information as early as possible to determine the supporting condition of the network, so that unnecessary processing is reduced. For example, the user equipment may obtain the relevant information by receiving the SSB, and the user equipment may also obtain the relevant information by receiving the PDCCH in the type0-PDCCH CSS determined by the information in the SSB. In both cases, the bandwidth of the associated control channel is less than 20MHz.

Optionally, the ue determines the indication information according to bit indication in DCI format 1_0 of SI-RNTI scrambling CRC. In release 17 and previous networks, the SI-RNTI sent by the base station scrambles the DCI of the CRC with a number of reserved bits not used to indicate valid information. For example, for an unshared spectrum cell, there are 15 reserved bits in the DCI. For example, when the indication information uses 2-bit indication, the user equipment determines the relevant indication information according to the first 2 bits of the reserved bits.

Optionally, the ue determines the indication information in the DCI only when the indication field System information indicator of the system information indication field System information indicator in DCI format 1_0 of the SI-RNTI scrambling CRC indicates 0, that is, when the PDSCH scheduled by the DCI carries SIB1 message.

There are also some reserved bits in the data transmitted by the PBCH channel sent by the network, which are not used for the indication of Release17 and the previous version of the system message or the network configuration. For example, in the MIB message transmitted by the PBCH, the spare field uses 1 bit as a padding bit of the MIB message, and does not represent valid information. There are also several transmission bits for network time related information in the PBCH, commonly denoted asWhen Lmax in the system is not 10 or 20 or 64, then the +.>To reserve bits, not used for transmissionEffective information. Here, lmax is the maximum sequence number of SSBs in the system, and can be determined according to the frequency band in which the SSBs are located. For example, in the cell where the user equipment detects the SSB on the frequency band of FR1, lmax takes a value of 4 or 8, and in the cell where the user equipment detects the SSB on the frequency band of FR2, lmax takes a value of 64.

Optionally, the ue determines the indication information according to a bit indication in the PBCH. For example, use in FR1 cells As a bit indication, the user equipment determines the relevant parameter hypothesis according to the indication information. The network may also define the use +.>Or the spark field in the MIB as a bit indication, it is also possible to use a combination with other bits, without further limitation.

[ example 2 ]

Fig. 2 is a flowchart of a method performed by a user equipment according to embodiment 2 of the present invention.

As shown in fig. 2, in step S201, the user equipment receives a synchronization signal/physical broadcast channel block SSB signal and obtains type0-PDCCH CSS related parameters.

In step S202, the user equipment detects the PDCCH according to the type0 PDCCH CSS, and obtains indication information.

In step S203, the user equipment determines a time parameter used by the user equipment according to the bandwidth parameter or the indication information.

The related processes are described in detail below.

In the NR network, the limitation of the processing time of the user equipment can be relaxed, so that the user equipment can have more processing time when receiving or transmitting data, thereby reducing the complexity of the related equipment. For example, in existing networks, the user equipment determines the minimum processing time required for the data transmission process. For example, the network defines a parameter for determining a minimum time interval between a last symbol of a PDSCH scheduled by the PDCCH received by the user equipment and a first symbol of a channel associated with the HARQ-ACK, and defines a parameter for defining a minimum time interval between a first symbol of a PUSCH scheduled by the PDCCH received by the user equipment and a last symbol of the associated PDCCH for N2. The timing of the user equipment, when performing the associated traffic scheduling, needs to meet the minimum interval determined according to these parameters. When the network supports the user equipment with wider time limit, especially when the processing time of receiving or transmitting the public data channel is widened, the user equipment needs to acquire proper instructions so that the understanding of the time relationship between the network and the user equipment is consistent, thereby ensuring the normal operation of the communication service.

Optionally, the user equipment determines the time parameter according to the bandwidth parameter. Optionally, the ue determines the time parameter for the common channel according to the bandwidth of CORESET 0. For example, the ue determines the adjustment coefficient of N1 according to the bandwidth of CORESET0, and a specific example is shown in table 2. The user equipment determines N1 used by the user equipment according to the coefficient value and a preset symbol value.

TABLE 2N 1 coefficients determined from CORESET0 Bandwidth parameter

The N1 used by the user equipment when receiving the PDSCH scheduled by the SI-RNTI or P-RNTI or TC-RNTI or RA-RNTI scrambled DCI of the CRC is the product of the determined N1 coefficient and the predefined PDSCH processing capability 1 and the number of PDSCH processing time symbols determined by the SCS used by the PDSCH.

For another example, the user equipment may determine an N1 value used when receiving a PDSCH scheduled by DCI of SI-RNTI or P-RNTI or TC-RNTI or RA-RNTI scrambling CRC according to a predetermined table. Specific examples are shown in table 3.

TABLE 3N 1 time parameter determined from CORESET0 Bandwidth parameter

Optionally, the ue determines a time parameter for the common channel according to the bandwidth of the uplink initial BWP. For example, the ue determines the coefficient of N2 according to the bandwidth of the uplink initial BWP, and a specific example is shown in table 4.

Table 4N 2 coefficients determined from initial upstream BWP bandwidth parameters

When the user equipment transmits the PUSCH scheduled by the uplink grant in the RAR message or the PUSCH scheduled by the DCI of the TC-RNTI scrambling CRC, the N2 used is the product of the determined N2 coefficient and the predefined PUSCH processing capability 1 and the PUSCH processing time symbol number determined by the SCS used by the PUSCH.

Alternatively, the user equipment may determine N2 used when PUSCH scheduled by uplink grant in the RAR message or PUSCH scheduled by DCI of TC-RNTI scrambling CRC according to a predetermined table. An example is shown in table 5.

Table 5N 2 time parameters determined from initial upstream BWP bandwidth parameters

Optionally, the ue indication information determines a reception or transmission time coefficient of a PUSCH scheduled by DCI for uplink grant scheduled PUSCH or TC-RNTI scrambling CRC or a PDSCH scheduled by DCI for RA-RNTI scrambling CRC. As a specific example, the user equipment determines the time parameter used from the indication information in the DCI of the RA-RNTI or msgB-RNTI scrambling CRC. For example using 1 bit to indicate the associated N1 coefficient or number of symbols of N1. Table 6 is an example of determining the relevant N1 and N2 coefficients. Tables 7 and 8 are examples of determining the values of N1 and N2 based on the indications.

TABLE 6N 1/N2 coefficients indicated by bits

Bit indication	0	1
			N1 coefficient	1	2
N2 coefficient	1	2

Table 7 number of N1 symbols indicated by bits

μ＝1	10	20

Table 8 number of N2 symbols indicated by bits

Bit indication	0	1
			μ＝0	10	20
μ＝1	12	24

Optionally, the indication information is an indication in DCI or an indication in a MAC layer message.

Alternatively, the user equipment determines the indication information only when the system information indication in the DCI is 0.

Optionally, the user equipment may determine a time parameter used by the user equipment in the related network according to the indication information in the DCI. The user equipment may determine the mode parameter according to first indication information in DCI format 1_0 of the SI-RNTI scrambling CRC, and may also determine indication information of the time parameter according to bit indication in DCI format 1_0 of the SI-RNTI scrambling CRC. For example, the relevant N1 and N2 are determined in accordance with the 1 bit indication in the DCI indication in combination with the method in the previous example.

Optionally, the ue determines the indication information according to a bit indication in the MAC layer message. When the network responds to the random access request of the user equipment by using the RAR message of the MAC layer, the user equipment can determine the time parameter according to the bit indication in the RAR message. For example, in the RAR message, there is one reserved bit before Time Advance Command information. The ue may determine relevant N1 and N2 parameters for the time parameters in the random access procedure based on the value of the bit.

[ example 3 ]

Fig. 3 is a flowchart for explaining a method performed by a user equipment according to embodiment 3 of the present invention.

As shown in fig. 3, in step S301, the user equipment receives a synchronization signal/physical broadcast channel block SSB signal and obtains type0-PDCCH CSS related parameters;

in step S302, the user equipment determines a time parameter;

in step S303, the ue can determine the PUSCH transmission resource according to the slot location and the time parameter indicated by the uplink grant in the RAR message.

The following examples describe the relevant processes in detail.

In an NR network, a user equipment expects that a time interval for scheduling or processing data in a data transmission process is not less than a specific value. In these processes, the user equipment can have more time to process data by relaxing the time limit of processing the service by the user equipment, so as to reduce the complexity of the user equipment. For example, a parameter of N1 for determining a minimum interval from a last symbol of PDSCH scheduled by a user equipment receiving PDCCH to an associated HARQ-ACK is defined in the network, and a parameter of N2 for determining a minimum interval from a last symbol of PUSCH scheduled by a user equipment receiving PDCCH to an associated PDCCH is defined. The timing of the user equipment, when conducting the relevant service, needs to meet the minimum interval determined according to these parameters. For example, the network transmits a random access response RAR message for responding to a random access request transmitted by the user equipment. The RAR message contains uplink scheduling information, which is used to instruct the ue to send Msg3 through the scheduled uplink resource. At this time, a minimum interval needs to be satisfied between the scheduled uplink PUSCH resource and the PDSCH transmitting the RAR message. In NR system, the minimum interval between the last symbol of PDSCH and the first symbol of PUSCH is N _T1 +N _T2 +0.5 milliseconds, where N _T1 For a time determined by N1 symbols, N _T2 For a time determined by N2 symbols. At the same time, uplink scheduling information contained in RAR messageThe timing information K2 is included to indicate the time domain position of the PUSCH resource. For example, the ue determines that PUSCH should be transmitted on time slot n+k2+Δ according to the indication, where n is the time slot number of the last time slot in which the PDSCH where the RAR message is located. K2 is the number of slots determined from a predetermined table or a higher-level configured parameter list according to the time domain resource allocation information in the grant information, and Δ is a predefined value determined according to PUSCH subcarrier SCS parameters. One specific example is shown in tables 9, 10, 11. The user equipment can determine a row sequence number according to the time domain resource allocation information in the DCI information, and obtain the number of symbols corresponding to K2 and delta used for PUSCH scheduling according to the row sequence number and the corresponding value of the SCS parameter in the table.

The user equipment may obtain lower complexity and other benefits by relaxing processing time. For example, the user equipment extends the time of N1, N2 to twice the value used by other types of user equipment. Thus, the user equipment is receiving PDSCH or PUSCH may allow for lower complexity devices to be used and more processing time to implement the relevant traffic functions. Some problems may arise when such a user equipment is in the same network as a user equipment that does not use time extension. For example, when the network sends the RAR grant, the used scheduling offset value may not meet the requirement of such user equipment after the processing time is relaxed, resulting in unsuccessful scheduling, affecting the availability of the system. For another example, the user equipment uses twice as much time as before after relaxation, and the minimum time interval of the relevant PDSCH and PUSCH determined by the user equipment will also be enlarged. The time value obtained from certain scheduling parameters may then be smaller than the minimum time interval. In a specific example, when the SCS performs data transmission on a bandwidth of 15kHz, the user equipment determines that N1 is 28 symbols and N2 is 20 symbols, which are twice the value used by other types of user equipment. SCS used for uplink and downlink data channels is 15kHz, mu _PUSCH Corresponding to a value of 0. If the value indicated by the time domain resource allocation information in the uplink grant received by the ue is 1, the ue determines the relevant scheduling timing according to the second row in table 9, and can determine that PUSCH should be transmitted on the time slot n+k2+Δ, where K2 is the time corresponding to 1 time slot, i.e. 14 symbols, Δ is the time corresponding to 2 time slots, i.e. 28 symbols, and the time interval indicated by k2+Δ is the time corresponding to 42 symbols, which is smaller than the time parameter N according to the time parameter N _T1 +N _T2 The minimum interval value determined by +0.5 milliseconds, i.e., 48 symbols +0.5 milliseconds. At this time, the actions of the user equipment and the network need to be properly adjusted so that the service can be performed normally.

Optionally, the interval between the PUSCH actually transmitted by the ue and the PDSCH used for transmitting the RAR message is less than the minimum processing interval determined by the ue, and the ue determines the PUSCH transmission resource according to the slot position indicated by the DCI format 0_1 of the uplink grant or TC-RNTI scrambling CRC in the RAR message and the time parameter.

Optionally, when the interval between the first symbol of the PUSCH scheduled by the uplink grant and the last symbol of the PDSCH used for transmitting the RAR message in the RAR message received by the user equipment is smaller than the minimum processing interval determined by the user equipment, the user equipment sends the PUSCH on the first available time slot meeting the minimum time interval after the time slot indicated by the time domain resource allocation parameter in the corresponding grant.

Alternatively, the available time slot is that the symbol determined according to the time domain resource allocation information is indicated as an uplink symbol by the higher layer information on the time slot. For example, the k2+Δ determined by the terminal according to the time domain resource allocation information in the uplink grant information is 42 symbols, or 3 slots, and the terminal determines that the slot number of the grant indication is n+3 on the slot after the PDSCH slot number n of the grant information is transmitted. If the minimum time interval required by the terminal equipment is N _T1 +N _T2 +0.5 is about 4 slots, then the terminal determines the symbol on the first available slot n+5 after n+4 slots as uplink, and the terminal uses these symbols for PUSCH transmission scheduled by the current uplink grant.

Alternatively, the available time slot is that the symbol determined according to the time domain resource allocation information is occupied by the SSB symbol indicated by the higher layer information as the downlink symbol or as the actually transmitted SSB symbol on the time slot.

Optionally, when the interval between the first symbol of the PUSCH scheduled by the uplink grant and the last symbol of the PDSCH used for transmitting the RAR message in the RAR message received by the user equipment is smaller than the minimum time interval determined by the user equipment, the user equipment sends the PUSCH on the first available time slot with a predefined offset from the time slot after the time slot indicated by the time domain resource allocation parameter in the corresponding grant or DCI.

Optionally, when no specific random access resource is configured for the user equipment in the network, when the interval between the first symbol of the PUSCH of the uplink grant schedule and the last symbol of the PDSCH for transmitting the RAR message in the RAR message received by the user equipment is smaller than the minimum processing interval determined by the user equipment, the user equipment sends the PUSCH on the first available time slot meeting the minimum time interval after the corresponding grant resource.

Optionally, when no specific random access resource is configured for the user equipment in the network, when the interval between the first symbol of the PUSCH of the uplink grant schedule and the last symbol of the PDSCH for transmitting the RAR message in the RAR message received by the user equipment is smaller than the minimum processing interval determined by the user equipment, the user equipment sends the PUSCH on an available time slot with a predefined offset from the corresponding grant resource location determined according to the RAR after the location.

Optionally, when the interval between the first symbol of PUSCH of the uplink grant schedule and the last symbol of PDSCH for transmitting the RAR message in the RAR message received by the user equipment is smaller than the minimum processing interval determined by the user equipment, the user equipment sends a MAC message, where the MAC message at least includes a type indication and TC-RNTI of the user equipment. After the user equipment sends the MAC message, the PDCCH using the TC-RNTI to scramble the CRC is monitored, a new uplink authorization value sent by the network is obtained, and msg3 is sent on the new scheduling resource.

Optionally, when the DCI carrying the TC-RNTI scrambles the CRC to schedule PUSCH transmission, the time slot interval between the PDCCH carrying the DCI and the PUSCH is K2, where the K2 used for scheduling may be smaller than the time parameter N2 required by the terminal, and the actual PUSCH transmission resource may be determined on the available time slot after the time slot indicated by the time domain resource allocation indication information of the DCI by a similar method as above.
