[0003] After completing uplink data transmission using public uplink transmission resources, a terminal device needs to receive downlink messages from the network device. Based on the received downlink messages, the terminal device can determine whether the uplink data transmission was successful. How the terminal device receives downlink messages is a problem that needs to be solved. Summary of the Invention

[0039] After completing uplink data transmission using public uplink transmission resources, a terminal device needs to receive a downlink message from a network device. Based on the received downlink message, the terminal device can determine whether the uplink data transmission was successful. However, in the prior art, how the terminal device determines the RNTI for receiving downlink messages for uplink data transmission using public uplink transmission resources has become a technical problem that needs to be solved urgently.

[0040] In an embodiment of the present invention, a terminal device may determine the RNTI based on parameters of an uplink pre-configured resource.

In some embodiments, the network device may also be a device that provides wireless communication functions for a terminal device, such as a chip system. For example, the chip system may include a chip and may also include other discrete devices.

[0044] In some embodiments, the network device may also communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks.

[0045] The embodiment of the present invention provides a data transmission method, referring to Figure 1 , the following is a detailed description through specific steps.

[0046] In an embodiment of the present invention, the data transmission method provided in the following steps 101 to 102 can be executed by a chip (such as a baseband chip) with data processing capabilities in the terminal device, or by a chip module with data processing capabilities in the terminal device, or by the terminal device. In the following embodiment, the execution of the method by the terminal device is used as an example for description.

[0047] Step 101: Acquire parameters of uplink pre-configured resources for uplink data transmission.

[0048] In a specific implementation, the network device may send the parameters of the uplink pre-configured resources to the terminal device via high-layer signaling. The high-layer signaling may be a system message, RRC signaling, etc. The terminal device may obtain the parameters of the uplink pre-configured resources via the high-layer signaling sent by the network device.

[0049] In embodiments of the present invention, uplink preconfigured resources may be used for uplink data transmission and are preconfigured by a network device for a terminal device. Unless otherwise specified, the uplink preconfigured resources described below in embodiments of the present invention may refer to uplink transmission resources that can be used by multiple terminal devices. Specifically, uplink preconfigured resources may also be referred to as public uplink transmission resources, shared uplink transmission resources, or contested uplink transmission resources.

[0050] In some embodiments, the uplink pre-configured resources may include physical uplink shared channel (PUSCH) pre-configured resources. It is understandable that with the development of communication technology, in subsequent evolved communication systems (such as 6G communication systems, 7G communication systems, etc.), there may be other uplink transmission resources that can be shared by multiple terminal devices.

[0051] Step 102: Determine a wireless network temporary identifier based on parameters of the uplink pre-configured resources.

[0052] In the embodiment of the present invention, the parameters of the uplink pre-configured resources may include: frequency domain resource parameters of the uplink pre-configured resources and time domain resource parameters of the uplink pre-configured resources.

[0053] In a specific implementation, the frequency domain resource parameter of the uplink pre-configured resource may include the frequency domain resource index number of the uplink pre-configured resource. The time domain resource parameter of the uplink pre-configured resource may include at least one of the following: the starting subframe number of the uplink pre-configured resource, the ending subframe number of the uplink pre-configured resource, the starting time slot number of the uplink pre-configured resource, and the ending time slot number of the uplink pre-configured resource.

[0054] In some embodiments, the RNTI of the terminal device may be obtained based on the following formula (1):

[0055] RNTI=1+t_PUSCH_id+X1×f_PUSCH_id; (1)

[0056] Among them, f_PUSCH_id is the frequency domain resource index number of the uplink pre-configured resource, t_PUSCH_id is any one of the starting subframe number, ending subframe number, starting time slot number, and ending time slot number of the uplink pre-configured resource; X1 is the first scaling factor.

[0057] That is to say, the RNTI of the terminal device can be determined based on any one of the starting subframe number, ending subframe number, starting time slot number, ending time slot number, etc. of the uplink pre-configured resources, as well as the frequency domain resource index number of the uplink pre-configured resources.

[0058] In a specific application, the value of X1 can be pre-configured by the network device or pre-specified in the communication protocol. For example, the value of X1 is 10. Another example is that the value of X1 is 20 or 30.

[0059] It should be noted that the above specific values of X1 are only for illustrative purposes and do not limit the values of X1.

[0060] In a specific implementation, the parameters of the uplink pre-configured resource may also include: the orthogonal code index corresponding to the uplink pre-configured resource. Thus, the RNTI of the terminal device may also be associated with the orthogonal code index of the uplink pre-configured resource. For an uplink pre-configured resource (such as a pre-configured PUSCH time-frequency resource), multiple terminal devices can be multiplexed for simultaneous transmission through the orthogonal code index.

[0061] In some embodiments, the RNTI of the terminal device may be obtained based on the following formula (2):

[0062] RNTI=1+t_PUSCH_id+X1×f_PUSCH_id+X2×OCC_index; (2)

[0063] Wherein, OCC_index is the orthogonal code index corresponding to the uplink preconfigured resource, and X2 is the second scaling factor. In specific applications, the value of X2 can be preconfigured by the network device or predefined in the communication protocol. The value of X2 can be 5, 10, 20, etc. It should be noted that the specific value of X2 described above is for illustrative purposes only and does not limit the value of X2.

[0064] In a specific implementation, when the parameters of the uplink pre-configured resources include the orthogonal code index corresponding to the uplink pre-configured resources, the above formula (1) may also be used to determine the RNTI of the terminal device. That is, when the parameters of the uplink pre-configured resources include the orthogonal code index corresponding to the uplink pre-configured resources, the RNTI of the terminal device may be determined with or without considering the orthogonal code index corresponding to the uplink pre-configured resources.

[0065] In a specific implementation, the time domain resource parameter of the uplink pre-configured resource may further include: a system frame number corresponding to the first subframe occupied by the uplink pre-configured resource.

[0066] In some embodiments, when the time domain resource parameter of the uplink pre-configured resource may also be the system frame number of the uplink pre-configured resource, the terminal device may determine the RNTI using the following formula (3):

[0067] RNTI=1+t_PUSCH_id+X1×f_PUSCH_id+X3×(SFN_PUSCH_id mod(Wmax / X4)); (3)

[0068] Among them, SFN_PUSCH_id is the system frame number corresponding to the first subframe occupied by the uplink pre-configured resources, X3 is the preset third scaling factor, X4 is the preset fourth scaling factor, Wmax is a preset value, and SFN_PUSCH_id mod (Wmax / X4) is SFN_PUSCH_id modulo (Wmax / X4).

[0069] In specific applications, the value of X3 can be pre-configured by the network device or pre-specified in the communication protocol. The value of X3 can be 20, 40, 60, etc. It should be noted that the specific value of X3 described above is only exemplary and does not limit the specific value of X3.

[0070] Accordingly, the value of X4 can be pre-configured by the network device or pre-specified in the communication protocol. The value of X4 can be 10, 20, 30, etc. It should be noted that the specific value of X4 described above is only exemplary and does not limit the specific value of X4.

[0071] The value of Wmax can be pre-configured by the network device or pre-specified in the communication protocol. The value of Wmax can be 200, 400, 800, etc. It should be noted that the specific value of Wmax mentioned above is only for example and does not limit the specific value of Wmax.

[0072] In a specific implementation, the parameters of the uplink pre-configured resource may further include: an orthogonal code index corresponding to the uplink pre-configured resource. In this scenario, the RNTI of the terminal device may also be associated with the orthogonal code index corresponding to the uplink pre-configured resource.

[0073] In some embodiments, the RNTI of the terminal device may be obtained based on the following formula (4):

[0074] RNTI=1+t_PUSCH_id+X1×f_PUSCH_id+X3×(SFN_PUSCH_id mod(Wmax / X4))+X2×OCC_index; (4)

[0075] The specific interpretations of X2 and OCC_index in formula (4) can refer to the description of formula (2) above, and will not be repeated here.

[0076] It is understandable that even if the parameters of the uplink pre-configured resources include the orthogonal code index corresponding to the uplink pre-configured resources, the RNTI of the terminal device can be determined based on the above formula (3), that is, the orthogonal code index corresponding to the uplink pre-configured resources can be ignored.

[0077] In the embodiment of the present invention, the parameters of the uplink pre-configured resources may include: a system frame number corresponding to the first subframe occupied by the uplink pre-configured resources, and a frequency domain resource parameter of the uplink pre-configured resources.

[0078] In a specific implementation, the frequency domain resource parameter of the uplink pre-configured resource may include a carrier index corresponding to the uplink pre-configured resource.

[0079] In some embodiments, the RNTI of the terminal device may be obtained based on the following formula (5):

[0080] RNTI=1+floor(SFN_PUSCH_id / 4)+X5×carrier_id; (5)

[0081] Among them, SFN_PUSCH_id is the system frame number corresponding to the first subframe occupied by the uplink pre-configured resources, X5 is the preset fifth scaling factor, carrier_id is the carrier index where the uplink pre-configured resources are located, and floor(SFN_PUSCH_id / 4) is SFN_PUSCH_id / 4 rounded down.

[0082] In specific applications, the value of X5 can be pre-configured by the network device or pre-specified in the communication protocol. The value of X5 can be 128, 256, 512, etc. It should be noted that the specific value of X5 mentioned above is only illustrative and does not limit the specific value of X5.

[0083] In a specific implementation, the parameters of the uplink pre-configured resource may further include: an orthogonal code index corresponding to the uplink pre-configured resource. In this scenario, the RNTI of the terminal device may also be associated with the orthogonal code index corresponding to the uplink pre-configured resource.

[0084] In some embodiments, the RNTI of the terminal device may be obtained based on the following formula (6):

[0085] RNTI=1+floor(SFN_PUSCH_id / 4)+X5×carrier_id+X2×OCC_index; (6)

[0086] The specific interpretations of X2 and OCC_index in formula (6) can refer to the description of formula (2) above, and will not be repeated here.

[0087] In the embodiment of the present invention, the time parameter of the uplink pre-configured resource may only include the time domain resource parameter of the uplink pre-configured resource.

[0088] In a specific implementation, the time domain resource parameters of the uplink pre-configured resources may include: the system frame number corresponding to the first subframe occupied by the uplink pre-configured resources, and the superframe number corresponding to the first subframe occupied by the uplink pre-configured resources.

[0089] In some embodiments, the RNTI of the terminal device may be obtained based on the following formula (7):

[0090] RNTI=1+floor(SFN_PUSCH_id / n1)+X6×(H-SFN_PUSCH mod n2); (7)

[0092] Wherein, SFN_PUSCH_id is the system frame number corresponding to the first subframe occupied by the uplink pre-configured resources, X6 is the preset sixth scaling factor, H-SFN_PUSCH is the superframe number corresponding to the first subframe occupied by the uplink pre-configured resources, floor(SFN_PUSCH_id / 4) is SFN_PUSCH_id / 4 rounded down, n1 is the first coefficient, and n2 is the second coefficient.

[0093] In specific applications, the value of X6 can be pre-configured by the network device or pre-specified in the communication protocol. The value of X6 can be 128, 256, 512, etc. It should be noted that the specific value of X6 mentioned above is only for example and does not limit the specific value of X6.

[0094] The value of n1 can be 2, 4, or 8, and the value of n2 can be 2, 4, or 8, etc. The values of n1 and n2 can also be pre-configured by the network device or pre-specified in the communication protocol. It should be noted that the above values of n1 and n2 are only exemplary and do not limit the specific values of n1 and n2.

[0095] In a specific example, the RNTI of the terminal device can be obtained based on the following formula (8):

[0096] RNTI=1+floor(SFN_PUSCH_id / 4)+X6×(H-SFN_PUSCH mod 2); (8)

[0097] In formula (8), the value of n1 is 4, and the value of n2 is 2.

[0098] Correspondingly, if the parameters of the uplink pre-configured resources also include the orthogonal code index corresponding to the uplink pre-configured resources, the RNTI of the terminal device can also be determined based on the following formula (9):

[0099] RNTI=1+floor(SFN_PUSCH_id / n1)+X6×(H-SFN_PUSCH mod n2)+X2×OCC_index; (9)

[0100] The specific interpretations of X2 and OCC_index in formula (9) can refer to the relevant descriptions in the above content and will not be repeated here.

[0101] In the embodiment of the present invention, the parameters of the uplink pre-configured resources may include time domain resource parameters of the uplink pre-configured resources, frequency domain resource parameters of the uplink pre-configured resources, OFDM symbol indexes of the uplink pre-configured resources, and the like.

[0102] In a specific implementation, the frequency domain resource parameters of the uplink pre-configured resources may include the frequency domain resource index number and the carrier index of the uplink pre-configured resources. The time domain resource parameters of the uplink pre-configured resources may include at least one of the following: the starting subframe number of the uplink pre-configured resources, the ending subframe number of the uplink pre-configured resources, the starting time slot number of the uplink pre-configured resources, and the ending time slot number of the uplink pre-configured resources.

[0103] In some embodiments, the RNTI of the terminal device may be determined using the following formula (10):

[0104] RNTI=1+s_PUSCH_id+X7×t_PUSCH_id+X7×X8×f_PUSCH_id+X7×X2×X9×carrier_id; (10)

[0105] Among them, s_PUSCH_id is the starting OFDM symbol index of the uplink pre-configured resource, X7 is the preset seventh scaling factor, X8 is the preset eighth scaling factor, X9 is the preset ninth scaling factor, and X2 is the preset second scaling factor.

[0106] In specific applications, the value of X7 can be pre-configured by the network equipment or pre-defined in the communication protocol. The value of X7 can be associated with the number of OFDM symbols in a time slot. For example, if the number of OFDM symbols in a time slot is 14, the value of X7 is 14.

[0107] The value of X8 can be pre-configured by the network device or pre-specified in the communication protocol. The value of X8 can be 40, 80, 120, etc. It should be noted that the specific value of X8 mentioned above is only for example and does not limit the specific value of X8.

[0108] The value of X9 can be pre-configured by the network device or pre-specified in the communication protocol. The value of X9 can be 2, 4, 8, 16, etc. It should be noted that the specific value of X9 mentioned above is only for example and does not limit the specific value of X9.

[0109] In a specific implementation, if the parameters of the uplink pre-configured resources also include the orthogonal code index corresponding to the uplink pre-configured resources, then based on the above formula (10), the method for the terminal device to determine the RNTI can also be expanded to the following formula (11):

[0110] RNTI=1+s_PUSCH_id+X7×t_PUSCH_id+X7×X8×f_PUSCH_id+X7×X9×carrier_id+X2×OCC_index; (11)

[0111] If the parameters of the uplink pre-configured resource also include a demodulation reference signal (DRMS) resource index of the uplink pre-configured resource, the manner in which the terminal device determines the RNTI can also be represented by the following formula (12):

[0112] RNTI=1+s_PUSCH_id+X7×t_PUSCH_id+X7×X8×f_PUSCH_id+X7×X2×X9×carrier_id+X10×DMRS resource_index;

[0113] Wherein, X10 is the preset tenth scaling factor, and DMRS resource_index is the demodulation reference signal DMRS resource index of the uplink pre-configured resource.

[0114] In a specific implementation, the DMRS resources may include a DMRS sequence and a DMRS antenna port, and different DMRS sequences or different DMRS antenna ports correspond to different DMRS resources.

[0115] The value of X10 can be pre-configured by the network device or pre-specified in the communication protocol. The value of X10 can be 2, 4, 8, 16, etc. It should be noted that the specific value of X10 described above is only exemplary and does not limit the specific value of X10.

[0116] If the parameters of the uplink pre-configured resource also include the DMRS resource index of the uplink pre-configured resource and the orthogonal code index corresponding to the uplink pre-configured resource, the terminal device can determine the RNTI based on the following formula (13):

[0117] RNTI=1+s_PUSCH_id+X7×t_PUSCH_id+X7×X8×f_PUSCH_id+X7×X2×X9×carrier_id+X2×OCC_index+X10×DMRS resource_index; (13)

[0118] In summary, in the embodiment of the present invention, the RNTI of the terminal device is determined based on the parameters of the uplink pre-configured resources (PUSCH) of the terminal device.

[0119] In an embodiment of the present invention, after determining the RNTI, the terminal device can receive a downlink message sent by the network device based on the RNTI. The downlink message can be a response message made by the network device to the uplink data transmission of the terminal device. The response message can be used to indicate the reception result (ACK / NACK) of the uplink data or the downlink data sent by the network device.

[0120] In a specific implementation, the downlink message may include downlink control information (DCI) or a physical downlink shared channel (PDSCH) scheduled by the DCI. Thus, the terminal device receives the downlink message through the determined RNTI, and further determines whether the network device has successfully received the transmitted uplink data.
