It should also be understood that, in this embodiment of the present application, the terminal device may include but is not limited to a mobile station (Mobile Station, MS), Mobile Terminal, Mobile Telephone, User Equipment (User) Equipment, UE), mobile phone (handset) and portable equipment (portable equipment), etc., the terminal equipment can pass through the radio access network (Radio Access Network, RAN) communicates with one or more core networks, for example, the terminal device may be a mobile phone (or "cellular" phone), a computer with wireless communication function, etc., and the terminal device may also be portable, pocket-sized, Handheld, computer built-in or in-vehicle mobile devices.

In this embodiment of the present application, the network device may be an access network device, for example, may be a base station, a transmitting and receiving point (Transmit and Receive Point (TRP) or access point, the base station can be a base station in GSM or CDMA (Base Transceiver Station, BTS), may also be a base station (NodeB) in WCDMA, or an evolved base station in LTE (evolved Node) B, eNB or e-NodeB) may also be an NR or a 5G base station (gNB), which is not specifically limited in this embodiment of the present application.

In order to facilitate the understanding of the solution, related concepts in the embodiments of the present application are first introduced.

The basic parameter set mentioned in the embodiment of the present application may include at least one of the following parameters:

Subcarrier spacing, number of subcarriers in a particular bandwidth, number of subcarriers in a physical resource block PRB, length of an orthogonal frequency division multiplexed OFDM symbol, Fourier transform for generating an OFDM signal, such as a fast Fourier transform ( Fast Fourier Transform ("FFT" for short) or inverse Fourier transform such as Inverse Fast Fourier Transform, abbreviated as "IFFT", the number of OFDM symbols in the transmission time interval TTI, the number of TTIs included in a specific time length, and the length of the signal prefix.

The subcarrier spacing refers to the frequency interval of adjacent subcarriers, for example, 15 kHz, 60 kHz, etc.; the number of subcarriers in a specific bandwidth is, for example, the number of subcarriers corresponding to each possible system bandwidth; the number of subcarriers included in the PRB, for example, Typically, it may be an integer multiple of 12; the number of OFDM symbols included in the TTI, for example, may be an integer multiple of 14; the number of TTIs included in a certain time unit may refer to 5 The number of TTIs included in the length of 1ms or 10ms; the length of the signal prefix such as the length of the cyclic prefix of the signal, or whether the cyclic prefix uses a regular CP or an extended CP.

In the NR standardization discussion, data can be transmitted between terminals and network devices using different types of basic parameter sets. Data can be transmitted using different base parameter sets on the same carrier or on different carriers. In general, different basic parameter sets can be distinguished by subcarrier spacing. For example, a basic parameter set corresponding to 15 KHz can be used as a reference basic parameter set. For example, the subcarrier spacing of other types of basic parameter sets may be 15 kHz×2n, and n is a non-negative integer; the number of slots included in one subframe of other types of basic parameter sets may be the time slot of the reference basic parameter set. The number 2n, n is a non-negative integer; one resource block RB of other types of basic parameter sets may be the same in the frequency domain as the number of subcarriers included in the frequency domain of the reference basic parameter set (for example, 12). When n=1, the subcarrier spacing in the basic parameter set is 30KHz, and the number of slots that one subframe can contain is four.

Currently discussed in the same carrier to multiplex different types of basic parameter sets, there are two main ways of multiplexing:

1, time division multiplexing (Time Division Multiplexing, TDM), that is, different basic parameter sets can be multiplexed in the time domain within the same bandwidth. It should be understood that the time periods corresponding to different basic parameter sets may be the same or different. Referring to Figure 2, the three different types of basic parameter sets contain different numbers of subcarriers in the same bandwidth. Assuming that each RB corresponds to 12 subcarriers, the number of subcarriers included in the first basic parameter set is 48, and the number of subcarriers included in the second basic parameter set is 24, and the third basic parameter set includes The number of subcarriers is 12.

2. Frequency Division Multiplexing (Frequency Division) Multiplexing, FDM), that is, different basic parameter sets can be multiplexed in the frequency domain during the same time interval. It should be understood that the bandwidths corresponding to different basic parameter sets may be the same or different. Each RB can correspond to 1 time slot. Referring to Figure 3, the three different types of basic parameter sets contain different numbers of time slots in the same time interval. For example, the first basic parameter set includes 1 time slot in the transmission time interval, the second basic parameter set includes 2 time slots in the transmission time interval, and the third basic parameter set includes 4 in the transmission time interval. Time slot.

Since data is transmitted using different basic parameter sets on the same carrier or different carriers, the terminal needs to determine which basic parameter set to use to transmit data when transmitting data, and the network device needs to indicate to the terminal through the DCI that the terminal transmits data. The base parameter set. However, this way of indicating the basic parameter set used for transmitting data to the terminal by means of DCI increases the overhead of transmitting DCI. In order to reduce the overhead of transmitting DCI, the method of data transmission in the embodiment of the present application is described in detail below with reference to FIG.

FIG. 4 is a schematic flowchart of a method for data transmission in an embodiment of the present application. The method shown in Figure 4 includes:

410. The terminal uses at least one first radio network temporary identifier RNTI to descramble the cyclic redundancy check code in the downlink control information (Cyclic) The Redundancy Check (CRC) determines that the first RNTI in the at least one first RNTI that successfully descrambles the CRC is the target RNTI.

Specifically, the foregoing first RNTI may be a basic parameter set wireless network temporary identifier (Numerology-Radio) The Network Tempory Identity (N-RNTI) may be used to indicate a basic parameter set. The name of the first RNTI is not specifically limited in this embodiment of the present application.

It should be noted that, if the terminal uses multiple RNs to descramble the CRC in the downlink control information, the terminal may descramble the CRC in the downlink control information according to the preset priority of the first RNTI, and the terminal may also be random. The CRC in the downlink control information is descrambled using a different first RNTI of the plurality of first RNTIs. The order in which the terminal uses the first RNTI descrambling is not specifically limited in this embodiment of the present application. Optionally, the at least one first RNTI is a plurality of first RNTIs, the multiple first RNTIs are all first RNTIs corresponding to the basic parameter set, and the first RNTIs are different among the multiple first RNTIs. Used to indicate different basic parameter sets.

It should be understood that the foregoing terminal may pre-store all the first RNTIs, and the terminal may also pre-store only a part of the first RNTI, which is not specifically limited in this embodiment of the present application.

It should also be understood that all of the above first RNTIs may refer to all first RNTIs specified by the protocol.

420. The terminal determines, according to the target RNTI, and the correspondence between the first RNTI and the basic parameter set, the target basic parameter set for transmitting data.

It should be noted that the correspondence between the first RNTI and the basic parameter set may be a correspondence between the first RNTI and the basic parameter set specified by the protocol, or may be a first RNTI and a basic indication that the network device indicates to the terminal by using the high layer signaling. The corresponding relationship of the parameter set is not specifically limited in this embodiment of the present application.

For example, the correspondence between the foregoing first RNTI and the basic parameter set may be as shown in Table 1. The 15KHz-RNTI is used to indicate a basic parameter set of 15KHz, the 30KHz-RNTI is used to indicate a basic parameter set of 30KHz, and the 60KHz-RNTI is used to indicate The basic parameter set of 60 KHz, 120 KHz-RNTI is used to indicate the basic parameter set of 120 KHz.

120KHz-RNTI 120KHz numerology

Optionally, as an implementation, the method further includes:

430. The terminal performs data transmission with the network device by using a transmission parameter in the target basic parameter set.

Optionally, as an embodiment, the method further includes: the terminal successfully descrambling the CRC in the downlink control information by using the second RNTI, and determining that the receiving end that receives the downlink control information is the terminal .

Specifically, the second RNTI is used to indicate the terminal that receives the downlink control information. If the terminal can use the pre-stored first RNTI to descramble the CRC in the downlink control information, the receiving end of the downlink control information is the terminal, that is, The foregoing second RNTI is used to uniquely identify the terminal.

It should be noted that the foregoing second RNTI may be different types of RNTIs according to different scenarios of the terminal. The foregoing second RNTI may be a C-RNTI for dynamically scheduled PDSCH transmission, may also be an RA-RNTI for a random access response, or may be an SI-RNTI for identifying a transmission of an SIB message, or may be The P-RNTI for identifying the transmission of the paging message may also be a TPC-RNTI for identifying the user group for joint coding TPC command transmission, for transmission of Msg3, and for conflict resolution. C-RNTI.

For example, when the terminal has data to be transmitted, the downlink control information may be downlink control information for indicating data transmission, and the CRC in the downlink control information may be scrambled by using a C-RNTI, and the second RNTI may be C. -RNTI. When the terminal is in an idle state and the terminal wants to access the network through random access, the downlink control signal may carry a random access response (Random) Access Response, RAR), the CRC in the downlink control information may be scrambled by the RA-RNTI, and the second RNTI may be an RA-RNTI.

It should be understood that the foregoing step 440 may be before step 410, that is, the terminal may first use the first RNTI to descramble the CRC in the downlink control information, and the terminal uses the second RNTI to descramble the CRC in the downlink control information; It is also possible after step 410, that is, the terminal may first descramble the CRC in the downlink control information using the second RNTI, and then use the first RNTI to descramble the CRC in the downlink control information. The order in which the terminal uses the first RNTI and the second RNTI to descramble the CRC in the downlink control information mainly depends on the order in which the first RNTI and the second RNTI scramble the CRC when the network device generates the downlink control information. For example, the network device first scrambles the CRC of the downlink control information by using the first RNTI, and then scrambles the CRC of the downlink control information by using the second RNTI, and the corresponding terminal needs to first perform the CRC of the downlink control information by using the second RNTI. De-scrambling, and then using the first RNTI to descramble the CRC of the downlink control information; if the network device first scrambles the CRC of the downlink control information by using the second RNTI, and then scrambles the CRC of the downlink control information by using the first RNTI The corresponding terminal needs to first descramble the CRC of the downlink control information by using the first RNTI, and then descramble the CRC of the downlink control information by using the second RNTI.

It should be further understood that the foregoing step of scrambling the CRC in the downlink control information by using the first RNTI and the second RNTI may be specified by a communication protocol, or the network device may indicate the terminal by using the high layer information.

Optionally, as an embodiment, the method further includes: the terminal successfully descrambling the CRC in the downlink control information by using the target RNTI, and determining that the receiving end of the downlink control information is the terminal .

Specifically, the foregoing first RNTI is further configured to uniquely identify the terminal. That is, after the terminal successfully descrambles the CRC through the target RNTI, the terminal may determine the basic parameter set indicated by the target RNTI, and may also determine that the receiving end that receives the downlink control information is the terminal.

Optionally, the at least one first RNTI is a plurality of first RNTIs, the multiple first RNTIs are all first RNTIs corresponding to the basic parameter set, and the first RNTIs are different among the multiple first RNTIs. Used to indicate different basic parameter sets.

Optionally, as an embodiment, the terminal uses the at least one first radio network temporary identifier RNTI to descramble the cyclic redundancy check code CRC in the downlink control information, and determines a successful descrambling in the at least one first RNTI. Determining, by the terminal, that the first RNTI of the CRC is the target RNTI, and determining that the first RNTI that successfully descrambles the CRC is the target RNTI, where the terminal descrambles the CRC by using at least one first RNTI in the first set. The first set includes the at least one first RNTI, and the transmission parameters in the basic parameter set indicated by each of the at least one first RNTI in the first set satisfy the transmission requirement of the first service.

It should be noted that the foregoing first service may be ultra-reliable low-latency communication (Ultra Reliable and Low). Latency Communication, URLLC) Service URLLC service can also be enhanced mobile broadband (enhance Mobile) Brondband, eMBB) business. If the first service is a URLLC service, the first set may include a basic parameter set that meets the service transmission requirement, for example, a basic parameter set corresponding to a subcarrier spacing of 60 kHz and/or a basic parameter set corresponding to a subcarrier spacing of 120 kHz; If the first service may be an eMBB service, the first set may include a basic parameter set that satisfies the service transmission requirement, for example, a basic parameter set corresponding to a subcarrier spacing of 15 kHz and/or a basic parameter corresponding to a subcarrier spacing of 30 kHz. set.

It should be further understood that the terminal may send the indication information to the network device, where the indication information is used to indicate the service type of the service to which the data to be transmitted belongs, and the terminal may also indicate, to the network device, the service of the service to which the data to be transmitted belongs when establishing the RRC with the network device. The specific manner of the service that the terminal indicates to the network device that the data to be transmitted belongs to is not limited.

Optionally, as an embodiment, the first set is a subset of the second set, and the second set includes all first RNTIs pre-stored by the terminal.

Specifically, the foregoing second set may include a first RNTI corresponding to all the basic parameter sets specified by the protocol, and the first set, as a subset of the second set, may include a corresponding basic parameter set that satisfies the first service transmission requirement. In an RNTI, the terminal may attempt to descramble the CRC in the downlink control information using only the first RNTI in the first set to determine the target RNTI.

For example, if the terminal supports the four basic parameter sets shown in Table 1, the first set may include four first RNTIs corresponding to the four basic parameter sets, and the second set may include 60KHz-RNTI and the first set. The 120KHz-RNTI, when the terminal needs to transmit the data of the URLLC service, the terminal may report the service type (for example, URLLC) of the service to which the data to be transmitted belongs to the network device, and the network device may perform the service according to the service to which the data to be transmitted by the terminal belongs. Type: Determine the target basic parameter set from the basic parameter set corresponding to 60KHz-RNTI and 120KHz-RNTI for the terminal to transmit data usage. Correspondingly, when the terminal performs descrambling on the CRC in the downlink control information, the CRC may be descrambled in the first RNTI from the first set, thereby preventing the terminal from determining the target from the first RNTI in the second set. The RNTI is to reduce the time at which the terminal determines the target RNTI by descrambling the CRC in the downlink control information.

Optionally, as an embodiment, the transmission parameter in the basic parameter set indicated by the first RNTI in the second set meets transmission requirements of multiple different services.

Specifically, the transmission parameters in the basic parameter set indicated by the first RNTI in the second set meet the transmission requirements of multiple services, such as a URLLC service and an eMBB service.

Optionally, as an embodiment, the method further includes: the terminal receiving configuration information sent by the network device, where the configuration information is used to configure the first set for the terminal.

Specifically, the network device may configure, for the terminal, only the first RNTI corresponding to the basic parameter set that the terminal meets the first service transmission requirement, that is, the first RNTI in the first set, and the basic parameter set that does not meet the first service transmission requirement. The first RNTI, the network device may not be configured for the terminal.
