- multimodal services add a dimension of tactile experience to users based on XR.
- tactile signals and video signals two different modes or different types of signals, remote touch and remote control can be realized, and remote perception in vision, hearing, touch, kinesthetics, etc. can be realized.
- tactile signals and video signals Due to the difference in human perception, tactile signals and video signals have different transmission requirements for the network. According to the current standard definition, the reliability requirement of video signals is 99%, the delay requirement is 10ms, and the reliability requirement of tactile signals is 99.999%, and the delay requirement is 5ms. Therefore, different reliability guarantees need to be adopted in physical layer transmission.
- the initial block error rate (iBLER) of the physical layer can be set to 1%, and after one retransmission and the cumulative addition of the combining gain, the transmission reliability requirement of 99.999% can be reached; within the 10ms delay requirement of the video signal, there are usually 2 to 3 retransmission opportunities, so the initial block error rate iBLER of the physical layer can be set to 10%.

- the first transmission method scheduling the tactile signal and the video signal in time slots;
- the TDD time slot ratio as "DDDSU", where "S” represents a special time slot, and the subcarrier interval is 30K Hz (i.e., the time length of a time slot is 0.5ms).
- Figure 2 shows the number of time slots in which no tactile signal arrives at the air interface within the video packet delay budget (PDB) under different numbers of tactile sensors (for example, the video packet delay budget is 10ms, and 20 time slots are required for transmission).
- the typical number of tactile transmitters for a single user is 60, including 40 tactile vests and 20 pairs of tactile gloves.
- the second transmission method described above consider transmitting the video signal together with the reliability requirements of the tactile signal.
- Transmission that is, the video signal is also transmitted using the transmission parameters corresponding to the tactile signal.
- Table 2 shows an example of the capacity data table of the video service after the video signal is transmitted together with the reliability requirement of the tactile signal.
- the current system supports scheduling two TBs (for example, TB1 and TB2) through one DCI.
- Each TB has independent MCS, NDI and RV configurations, but the time domain resources and frequency domain resources occupied by the two TBs are the same.
- the multimodal services of the video signal (video data) and the tactile signal (tactile data) may be transmitted in the following manner: tactile data is transmitted using TB1, and video data is transmitted using TB2.
- the two TBs use independent MCS, NDI and RV configurations, and the two TBs occupy different space division resources respectively.
- the total space division multiplexing resources have 8 layers, the first 4 layers carry TB1 for transmitting tactile data, and the last 4 layers carry TB2 for transmitting video data.
- the above method is used to transmit the video signal and the tactile signal. Since the data volume of the video signal and the tactile signal is quite different, for example, for a 30Mbps@60FPS video, the size of a single video frame is 60 to 100K bytes, and the size of each tactile data packet is 12 to 48 bytes. Considering that there are 60 tactile sensors on the downlink user side, after tactile compression, the average number of tactile data packets that need to be transmitted per time slot in the air interface is about 20, and the total size of the tactile data volume is 240 to 960 bytes.
- the tactile data volume only needs about 2 to 3 resource block groups (RBGs) to complete the transmission (generally speaking, the number of RBGs that a user can occupy in a time slot (i.e., within the time of a TB transmission) is in the order of tens). Since the amount of data required to be carried by the TB for transmitting tactile data is relatively small, while the amount of data required to be carried by the TB for transmitting video data is relatively large, if these two TBs occupy the same frequency domain resources and time domain resources, the resource utilization rate of the TB for transmitting tactile data will be relatively low (for example, more padding bits need to be added).
- RBGs resource block groups
- the present application provides a method for data transmission, which transmits first data (the first data may be, for example, video data) on a part of time-frequency resources on the same layer of space division resources (for example, the first space division resources), and transmits second data (the second data may be, for example, tactile data) on another part of time-frequency resources on the same layer of space division resources, or transmits the second data on another layer of space division resources (for example, the second space division resources).
- Two different sets of MCS, NDI and RV are used for transmitting the first data and the second data, respectively, and the first space division resources and the second space division resources correspond to the same time-frequency resources.

- the space-division resources included in the first part of the space-division resources and the space-division resources included in the second part of the space-division resources can be configured in advance, or can be indicated in the DCI.
- indication information can be added in the RRC to indicate that a part of the time-frequency resources (third time-frequency resources) allocated by the DCI should be divided from front to back (or from back to front) according to time (i.e., according to the time domain) and the remaining part should be the second time-frequency resources.

- the "SecondTB-ENABLE" field indicates "using (or activating) the second transmission parameter", as shown in FIG. 12, the first part of the second MCS field in the DCI (for example, the first two bits of the second MCS field) is used to indicate the second MCS.

- some bits in the second MCS field can be used to indicate: in the time-frequency resources (i.e., the third time-frequency resources) of the first spatial resources allocated by the DCI, the sizes of the first time-frequency resources and the second time-frequency resources, and different bit values can represent different division ratios or division forms of the third time-frequency resources.
- the above-mentioned DCI may also be called “second indication information”.
- the second RV field can be reduced from the original 2-bit length to 1-bit length, and the remaining 1 bit of the second RV field and the second part of the second MCS field (for example, the last three bits of the second MCS field) jointly indicate the first time-frequency resource and the second time-frequency resource.
- part of the bits in the second MCS field and part of the bits in the second RV field can be used to jointly indicate: in the time-frequency resources of the first space-division resources allocated by the DCI (i.e., the third time-frequency resources), the sizes of the first time-frequency resources and the second time-frequency resources, and different bit values can represent different division ratios or division forms of the third time-frequency resources.
- the first time-frequency resource and the second time-frequency resource can be indicated by DCI, and there is no need to add additional fields in the DCI to indicate the first time-frequency resource and the second time-frequency resource, which can save communication resources and improve the utilization rate of communication resources.
- the network device may send an RRC with "whether to use (or activate) the second transmission parameter" added thereto and the above-mentioned DCI to the terminal device.
- the network device can use the transmission parameters of TB1 (the first MCS, the first NDI, and the first RV) to send tactile data to the terminal device in the first time-frequency resource in the third time-frequency resource, and use the transmission parameters of TB2 (the second MCS, the second NDI, and the second RV) to send video data to the terminal device in the second time-frequency resource in the third time-frequency resource.

- the terminal device uses (automatically uses) the transmission parameters of TB1 (the first MCS, the first NDI, and the first RV) by default to receive the first data (for example, tactile data) on the first time-frequency resource, and uses the transmission parameters of TB2 (the second MCS, the second NDI, and the second RV) to receive the second data (for example, video data) on the second time-frequency resource.
- the value of the "maxNrofCodeWordsScheduledByDCI" field in the RRC signaling is 1, and the RRC indicates "using (or activating) the second transmission parameter"
