Background

In the fifth generation mobile communication technology (5G) technology, a User Equipment (User Equipment, abbreviated as "UE") may support multiple different base parameter sets (numerology) within one carrier. These different sets of base parameters may be multiplexed by Time Division multiplexing ("TDM") or Frequency Division multiplexing ("FDM"). For example, in the same Transmission Time Interval (TTI), different frequency domain resources may be allocated to data Transmission using different sets of base parameters. In order to reduce the complexity of blind detection of the Control Channel, data transmission using different basic parameter sets and performing FDM multiplexing may be scheduled based on a common Control Channel, for example, a Physical Downlink Control Channel (PDCCH). Since the control information required for data transmission based on different sets of elementary parameters may be different, how to schedule data transmission based on different sets of elementary parameters is an urgent problem to be solved.

The network device 20 is used to provide a communication service to the terminal device 10 and access a core network, and the terminal device 10 accesses the network by searching for a synchronization signal, a broadcast signal, or the like transmitted by the network device 20, thereby performing communication with the network.

The embodiment of the invention can improve the flexibility of control signaling design by scheduling data transmission based on different basic parameter sets by using different DCI formats in a common control channel.

Fig. 2 shows a schematic flow diagram of a method of data transmission according to an embodiment of the invention. A terminal device 10 and a network device 20 are shown in fig. 2. As shown in fig. 2, the specific flow of transmitting data includes:

network device 20 determines 210 the set of base parameters to use for transmitting the data.

For example, the network device 20 may determine a basic parameter set for performing the data transmission among a plurality of basic parameter sets, so as to determine Downlink Control Information (DCI) to be sent to the terminal device 10 according to the basic parameter set.

Wherein the base parameter set may include at least one resource parameter for determining time-frequency resources for transmitting the data.

Optionally, the base parameter set may include at least one of the following parameters:

the number of subcarriers in a specific bandwidth, the number of subcarriers in a physical resource block PRB, the length of an orthogonal frequency division multiplexing OFDM symbol, the number of points of a Fourier Transform such as Fast Fourier Transform (FFT) or an Inverse Fourier Transform such as Inverse Fast Fourier Transform (IFFT) for generating an OFDM signal, the number of OFDM symbols in a transmission time interval TTI, the number of TTIs included within a specific time length, and the length of a signal prefix.

220, the network device 20 transmits DCI for scheduling the data to the terminal device 10 according to the basic parameter set.

Specifically, in the embodiment of the present invention, multiple different basic parameter sets may be supported in the same carrier, and the different basic parameter sets may be multiplexed in a TDM or FDM manner. For example, in the same TTI, different frequency domain resources may be allocated for data transmission based on different sets of underlying parameters; or different TTIs may be used for data transmission based on different sets of underlying parameters. Data transmissions based on different sets of underlying parameters may be scheduled through a common control channel or separate control channels. After network device 20 determines the base parameter set, DCI for scheduling the data may be transmitted to terminal device 10 according to the base parameter set.

It should be understood that the network device 20 may select an appropriate Channel according to different requirements to schedule the data based on different basic parameter sets, the network device 20 may schedule the data based on different basic parameter sets in a common Control Channel, for example, the network device 20 sends DCI for scheduling the data to the terminal device 10 through a Physical Downlink Control Channel (PDCCH), and the network device 20 may also schedule the data based on different basic parameter sets through an independent Control Channel, which is not limited herein.

Alternatively, the network device 20 may transmit DCI for scheduling the data to the terminal device 10 according to at least one parameter in the basic parameter set; or the network device 20 may determine the DCI format of the DCI according to the basic parameter set and the corresponding relationship between the basic parameter set and the DCI format, and send the DCI for scheduling the data to the terminal device 10 according to the DCI format.

Specifically, the network device 20 may determine a physical resource for scheduling DCI of the data based on at least one parameter in the basic parameter set, and then transmit the DCI for scheduling the data to the terminal device 10 on the determined physical resource. For example, the network device 20 may determine the number of subcarriers and the number of PRBs occupied by the control channel carrying the DCI based on the subcarrier spacing in the basic parameter set, so as to transmit the DCI to the terminal device 10 in the control channel on the corresponding subcarriers and PRBs.

Network device 20 may also determine the DCI format of the DCI for scheduling the data according to the determined basic parameter set and the corresponding relationship between the basic parameter set and the DCI format, and send the DCI for scheduling the data to terminal device 10 according to the DCI format.

For example, assuming that the base parameter set includes subcarrier spacing, the corresponding relationship between the base parameter set and the DCI format may be as shown in table one. Wherein, the subcarrier interval used for data transmission on the first frequency band is 15kHz, and the corresponding DCI format is DCI format 1(DCI format 1); the subcarrier interval used for data transmission on the second frequency band is 30kHz, and the corresponding DCI format is DCI format 2; the subcarrier interval used for data transmission in the third frequency band is 60kHz, and the corresponding DCI format is DCI format 3; the subcarrier interval used for data transmission in the fourth frequency band is 120kHz, and the corresponding DCI format is DCI format 4.

Watch 1

Subcarrier spacing	DCI format
		15kHz	DCI format 1
30kHz	DCI format 2
		60kHz	DCI format 3
120kHz	DCI format 4

For a fixed system bandwidth, the number of subcarriers corresponding to different subcarrier intervals is different, the number of corresponding downlink total Physical Resource Blocks (PRB) is also different, and the number of bits required for frequency domain Resource allocation is also different. The number of bits in the frequency domain resource allocation domain in the DCI format corresponding to different subcarrier intervals is different, and the total number of bits included in different DCI formats is also different. For example, assuming that the number of bits in the frequency domain resource allocation field included in each DCI format is M, M-k, M-2k, and M-3k, the number of control information bits included in the four DCI formats is N, N-k, N-2k, and N-3k, respectively.

The network device 20 may determine the DCI format of the DCI for scheduling the data according to the determined base parameter set and the corresponding relationship between the base parameter set and the DCI format, so as to transmit the DCI to the terminal device 10 according to the DCI format.

Therefore, the data transmission based on different basic parameter sets can be scheduled by adopting different DCI formats, and the flexibility of control signaling design is increased.

It should be understood that the corresponding relationship between the basic parameter set and the DCI format may be determined by the network device 20 itself, or may be predetermined between the network device 20 and the terminal device 10.

The terminal device 10 detects the downlink control information DCI for scheduling the data 230.

Specifically, the terminal device 10 detects downlink control information DCI for scheduling the data, which is transmitted by the network device 20. For example, the terminal device may detect DCI for scheduling the data based on different DCI formats until the DCI is correctly detected according to a certain DCI format.

The terminal device 10 determines 240 a base parameter set for transmitting the data according to the detected DCI.

Specifically, after the terminal device 10 detects the DCI based on the possible DCI formats, the base parameter set for transmitting the data may be determined according to the detected DCI.

In this way, the network device 20 does not need to notify the terminal device 10 of the basic parameter set used for data transmission to be performed currently, and overhead of downlink signaling can be saved.

Optionally, the terminal device 10 may determine the basic parameter set for transmitting the data according to a detected Cyclic Redundancy Check (CRC) code (which may be referred to as a CRC Check code) of the DCI. For example, the terminal device 10 may determine the basic parameter set for transmitting the data according to the length of the CRC check code or the content of the CRC check code.

Optionally, the terminal device 10 may further determine the basic parameter set for transmitting the data according to the detected DCI format of the DCI and the correspondence between the DCI format and the basic parameter set.

For example, possible formats of DCI for scheduling the data are DCI format 1, DCI format 2, DCI format 3, and DCI format 4. The terminal device detects DCI transmitted by the network device 20 through the PDCCH based on these possible DCI formats. As shown in the above table one, the four DCI formats may correspond to the size of one subcarrier interval. Assuming that the terminal device 10 correctly detects DCI sent by the network device 20 based on the DCI format 1, the terminal device 10 determines that the subcarrier interval corresponding to the detected DCI format 1 is 15kHz according to the correspondence between the DCI format and the subcarrier interval shown in table one. The terminal device 10 detects a Physical Downlink Shared Channel (PDSCH) scheduled by the DCI according to the determined subcarrier spacing. For example, the terminal device 10 may determine the number of subcarriers and the number of PRBs on the first frequency band, the number of time-domain sample points corresponding to one OFDM symbol, and the number of OFDM symbols included in one TTI according to the subcarrier spacing. And then, according to the parameters and the control information in the DCI, detecting the data scheduled by the DCI.

For another example, possible formats of DCI for scheduling the data include DCI format 1, DCI format 2, DCI format 3, and DCI format 4, and the correspondence between the DCI format and the basic parameter set is shown in table two. Based on these possible DCI formats, terminal apparatus 10 detects DCI transmitted by network apparatus 20 through the PDCCH. The four DCI formats contain the same number of control information bits, and the first two control information bits are used to distinguish different DCI formats. Assuming that the terminal device 10 correctly detects DCI transmitted by the network device 20 based on the DCI format 2, according to a predetermined correspondence between the DCI format and the basic parameter set, it determines that the basic parameter set corresponding to the detected DCI format 2 is a second basic parameter set, and the terminal device 10 performs detection on the PDSCH scheduled by the detected DCI according to the determined parameters in the second basic parameter set. For example, the terminal may determine, according to the subcarrier spacing, the total subcarrier number, and the channel prefix length in the basic parameter set, and in combination with other control information in the DCI, a parameter for detecting the PDSCH scheduled by the DCI, so as to detect the PDSCH scheduled by the DCI.

DCI format	Basic parameter set
		DCI format 1	First basic parameter set
DCI format 2	Second basic parameter set
		DCI format 3	Third basic parameter set
DCI format 4	Fourth basic parameter set

Optionally, the length of control information corresponding to different DCI formats is different, and/or information indicated by DCI format indication bits included in different DCI formats is different.

Optionally, if the basic parameter sets corresponding to different DCI formats are different, and the different DCI formats include the same control information field, the number of bits occupied by the same control information field in the different DCI formats is different, and/or the content indicated by the same control information field in the different DCI formats is different.

The length of the DCI refers to the total number of bits of the control information included in the DCI, and the content of the DCI refers to the control information fields included in the DCI and the content indicated by the control information fields.

Specifically, different DCI formats correspond to different sets of basic parameters, and the different DCI formats may be distinguished by at least one of a length of DCI, content of control information in DCI, a length of a control information field, and content indicated by the control information field. That is, the DCI lengths corresponding to different DCI formats are different, and/or the content of the control information in the DCI corresponding to different DCI formats is different, and/or the number of bits occupied by the same control information field in the DCI corresponding to different DCI formats is different for the same control information field, and/or the content indicated by the same control information field in the DCI corresponding to different DCI formats is different for the same control information field.

The DCI formats corresponding to different DCI formats may have different lengths, for example, the DCI format corresponding to the first basic parameter set is DCI format 1, the DCI format corresponding to the second basic parameter set is DCI format 2, and the information bits included in the DCI formats 1 and 2 are different; the content of the control information in the DCI corresponding to different DCI formats may be different, for example, the DCI format corresponding to the first basic parameter set is DCI format 1, the DCI format corresponding to the second basic parameter set is DCI format 2, and DCI format 1 has one more control information field than DCI format 2. For the same control information field, the number of bits occupied by the same control information field in the DCIs corresponding to different DCI formats may be different, for example, the DCI format corresponding to the first base parameter set is DCI format 1, the DCI format corresponding to the base parameter set 2 is DCI format 2, and both DCI format 1 and format 2 include a control information field for indicating Resource Block (RB) allocation, but because the frequency domain Resource regions corresponding to the two base parameter sets are different, the number of bits of the control information field for indicating RB allocation is also different; for the same control information field, the content indicated by the same control information field in the DCIs corresponding to different DCI formats may also be different, for example, the DCI format corresponding to the first basic parameter set is DCI format 1, the DCI format corresponding to the second basic parameter set is DCI format 2, the DCI format corresponding to the third basic parameter set is DCI format 3, the DCI format corresponding to the fourth basic parameter set is DCI format 4, the four DCI formats all include a 2-bit control information field indicating ACK/NACK feedback timing, which is used to indicate a timing relationship between data transmission and corresponding ACK/NACK, and for the DCI format 1 corresponding to the first basic parameter set, four possible timings indicated by the control information field are {0, 1, 2, 3 }; for DCI format 2 corresponding to the second basic parameter set, the four possible timings indicated by the control information field are {0, 2, 4, 6 }; for DCI format 3 corresponding to the third basic parameter set, the four possible timings indicated by the control information field are {0, 3, 6, 9 }; for DCI format 4 corresponding to the fourth basic parameter set, the four possible timings indicated by the control information field are {0, 4, 8, 12 }; the content indicated by the control information field in different DCIs corresponding to different basic parameter sets is different.

For example, the DCI format and the base parameter set may correspond to each other as shown in table two above. The corresponding basic parameter set is a first basic parameter set when the DCI format is DCI format 1, the corresponding basic parameter set is a second basic parameter set when the DCI format is DCI format 2, the corresponding basic parameter set is a third basic parameter set when the DCI format is DCI format 3, and the corresponding basic parameter set is a fourth basic parameter set when the DCI format is DCI format 4. After the terminal device 10 detects the DCI sent by the network device 20 based on the DCI format 2, the terminal device 10 may determine, according to the corresponding relationship between the DCI format and the basic parameter set, that the basic parameter set used for data transmission is the basic parameter set two. The basic parameter set may include parameters such as subcarrier spacing, number of subcarriers in current system bandwidth, signal prefix length, and the like. The network device 20 may send the parameter configuration conditions in the first basic parameter set, the second basic parameter set, the third basic parameter set, and the fourth basic parameter set to the terminal device 10 in advance, and the terminal device 10 receives the parameter configuration conditions in the basic parameter sets. Assume that all of the four DCI formats include a 2-bit control information field for indicating an Acknowledgement/non-Acknowledgement (ACK/NACK) feedback timing, specifically indicating a subframe offset between a data transmission subframe and an ACK/NACK feedback subframe. Alternatively, the number of bits occupied by the control information field in different DCI formats may be different, for example, the number of bits of control information included in DCI format 1 and DCI format 3 is the same (assumed to be M), and the number of bits of control information included in DCI format 2 and DCI format 4 is the same (assumed to be N). Optionally, for different DCI formats corresponding to different parameter configuration groups, the DCI formats may also all include a control information field with 2 bits for indicating ACK/NACK feedback timing, but the content indicated by the control information field with 2 bits for indicating ACK/NACK feedback timing may be different, for example, as shown in table three.

DCI format	Indicated subframe offset value
		DCI format 1	{0，1，2，3}
DCI format 2	{0，2，4，6}
		DCI format 3	{0，3，6，9}
DCI format 4	{0，4，8，12}

After the terminal device 10 detects DCI transmitted by the network device 20 based on a certain DCI format, the terminal device 10 may determine at least one of the length of the DCI, the content of the control information in the DCI, the number of bits occupied by a certain control information field in the DCI, and the content indicated by the certain control information field in the DCI according to the DCI format, and determine a basic parameter set for transmitting the data according to a corresponding relationship between the DCI format and the basic parameter set.

Optionally, the control information field in the DCI format may include at least one of:

a control information field for indicating physical resource allocation, a control information field for indicating ACK/NACK feedback timing, a control information field for indicating frequency hopping configuration, a control information field for indicating Modulation Coding Scheme (MCS), a control information field for indicating subframe structure, and a control information field for indicating demodulation Reference Signal (DMRS) configuration.

Wherein, the control information field for indicating physical resource allocation may be, for example, an RB allocation information field of a PRB occupied for indicating data transmission of the DCI scheduling; the control information field for indicating the ACK/NACK feedback time sequence is used for indicating the time sequence relation between data transmission and corresponding ACK/NACK feedback, such as the sub-frame offset number between the sub-frame where the data transmission is located and the sub-frame where the corresponding ACK/NACK feedback is located; the control information field for indicating the frequency hopping configuration is, for example, a control information field for indicating frequency domain frequency hopping; the control information field for indicating the DMRS configuration is, for example, a control information field for indicating information such as a port used by the DMRS and a scrambling sequence; the control information field for indicating the subframe structure is, for example, a field for indicating the number of total Orthogonal Frequency Division Multiplexing (OFDM) symbols in a subframe, or the number or position of Guard Periods (GP) in a subframe, or the number configuration of different types of OFDM symbols in a subframe, such as the number or ratio configuration of downlink control symbols, downlink data symbols, and uplink control symbols in a subframe, or the number or ratio configuration of downlink control symbols and uplink data symbols in a subframe.

Optionally, 241 to 244 may also be included in the method 240. Fig. 3 is a schematic flow chart of a method of transmitting data according to another embodiment of the present invention. The method includes 241 to 244, wherein 240 may be replaced by 241 to 244.

241, the network device 20 determines the correspondence between the DCI format and the base parameter set.

242, the network device 20 transmits indication information indicating the correspondence relationship to the terminal device 10.

243, the terminal device 10 receives the indication information indicating the correspondence sent by the network device 20.
