Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

The terms "first", "second" and the like in the description and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of practice in sequences other than those illustrated or described herein.

Referring to FIG. 1 , an embodiment of the present invention provides a method for determining uplink data transmission. The execution subject of the method is a terminal supporting OMA and NOMA transmission, and the terminal includes but is not limited to a mobile phone, a tablet computer, a notebook computer, a palmtop computer, Car terminals, wearable devices, and pedometers, etc., the specific steps of the method are as follows:

Step 101: Receive first radio resource control (Radio Resource Control, RRC) signaling or second RRC signaling sent by a network device.

Wherein, the first RRC signaling includes: a first field and/or a second field, the first field may be used to implicitly or explicitly indicate whether to enable dynamic indication of OMA or NOMA transmission mode; the second field may It is used to implicitly or explicitly indicate the default transmission mode. The default transmission mode can be OMA or NOMA transmission mode.

For example: the first RRC signaling may be Physical Uplink Shared Channel (Physical Uplink SharedChannel, PUSCH)-configuration (Config) signaling, and the following dynamicMAmodeindication field and multiple access (Multiple Access, MA) mode (mode) field, where the dynamicMAmodeindication field can be used to indicate whether to enable the dynamic indication OMA or NOMA transmission mode. When the dynamicMAmodeindication field indicates disabled, it means that the dynamic indication OMA or NOMA transmission mode is not enabled. When the dynamicMAmodeindication field indicates enabled The meaning of is to enable the dynamic indication of OMA or NOMA transmission mode, and the MA mode field is used to indicate the default transmission mode of not enabling the dynamic indication of OMA or NOMA transmission mode.

Meanwhile, in another embodiment of the present invention, the second RRC signaling includes: a first radio network temporary identifier (Radio Network Temporary Identifier, RNTI) and NOMA configuration information for DCI scrambling, and the first RNTI The scrambled DCI is used to dynamically indicate that the NOMA transmission mode is adopted.

For example: the second RRC signaling can be NOMA-Config signaling, and the following fields are added to the NOMA-Config signaling. At this time, the second RNTI is defined as NOMA-C-RNTI, and the NOMA-C-RNTI is added The scrambled DCI is used to dynamically instruct the terminal to adopt NOMA transmission.

Step 102: Determine a transmission mode for sending uplink data according to the first RRC signaling or the second RRC signaling.

Since the information contained in the first RRC signaling is different from that contained in the second RRC signaling, there are the following situations for determining the transmission mode for sending uplink data.

Scenario 1:

When the first RRC signaling includes the first field and the second field, and the first field indicates that the dynamic indication OMA or NOMA transmission mode is not enabled, the default transmission indicated by the second field mode, which is determined as a transmission mode for sending uplink data, wherein the default transmission mode is OMA or NOMA transmission mode.

For example: the first RRC signaling is PUSCH-Config signaling, when the dynamicMAmodeindication field in the PUSCH-Config signaling received by the terminal indicates invalidation (disabled), and the MA mode field indicates OMA, the terminal needs to detect network equipment Whether the sent DCI is scrambled by C-RNTI. When the terminal detects that the DCI sent by the network device is scrambled by C-RNTI, it reads the scheduling information in the DCI according to the first DCI format corresponding to the OMA method and uses OMA for transmission way to send uplink data. Wherein, the first DCI format is shown in Table 1.

Table 1 The first DCI format corresponding to the OMA method

Another example: when the dynamicMAmodeindication field in the PUSCH-Config signaling received by the terminal indicates disabled, and the MA mode field indicates NOMA, the terminal only needs to detect whether the DCI sent by the network device is scrambled by NOMA-C-RNTI, when the terminal When it is detected that the DCI sent by the network device is scrambled through the NOMA-C-RNTI, the scheduling information in the DCI is read according to the second DCI format corresponding to the NOMA mode, and the uplink data is sent in the NOMA mode. Wherein, the format of the second DCI is shown in Table 2.

Table 2 The second DCI format corresponding to the NOMA method

Through comparative analysis of Table 1 and Table 2, it can be seen that the difference between the first DCI format and the second DCI format is that the second DCI format includes at least the MA signature related bit field and the user equipment (User Equipment, UE) indication field, where the MA The signature-related bit field can be used to implicitly or explicitly indicate the Multiple Access (Multiple Access, MA) codebook used by the terminal, and the UE indication field is used to dynamically indicate the set of terminals scheduled by the current DCI. Since the uplink channel uses NOMA transmission to carry a large number of terminals, in order to reduce the overhead of DCI, DCI indication based on terminal groups can be used, so the UE indication field is introduced in DCI to dynamically indicate the set of terminals scheduled by the current DCI .

Scenario 2:

When the first RRC signaling includes the first field, the first field indicates that the OMA or NOMA transmission mode is enabled dynamically, and the terminal detects that the DCI sent by the network device is scrambled by the first RNTI , read the scheduling information in the DCI according to the NOMA configuration information and send the uplink data in the NOMA transmission mode.

Case three:

When the first RRC signaling contains the first field, the first field indicates that the OMA or NOMA transmission mode is enabled dynamically, and the terminal detects that the DCI sent by the network device is scrambled by the second RNTI , reading the scheduling information in the DCI according to the OMA configuration information and sending the uplink data in an OMA transmission manner.

For example: when the dynamicMAmodeindication field in the PUSCH-Config signaling received by the terminal is indicated as enabled, the terminal needs to detect whether the DCI sent by the network device is scrambled by C-RNTI or NOMA-C-RNTI. When the terminal detects When the DCI sent by the network device is scrambled by C-RNTI, read the scheduling information in the DCI according to the first DCI format and configuration corresponding to the OMA method, and use the OMA transmission method to send uplink data; when the terminal detects the DCI sent by the network device When the NOMA-C-RNTI is used for scrambling, the scheduling information in the DCI is read according to the second DCI format and configuration corresponding to the NOMA mode, and the uplink data is sent using the NOMA transmission mode.

After step 202, the method further includes: using the corresponding RNTI to detect DCI according to the default transmission mode, and reading the scheduling information in the DCI according to the configuration information corresponding to the default transmission mode, and according to the default The transmission method sends uplink data. Step 203: When the first RRC signaling contains the first field, the first field indicates that the OMA or NOMA transmission mode is enabled dynamically, and the terminal detects that the DCI sent by the network device is through the first RNTI When scrambling, the scheduling information in the DCI is read according to the NOMA configuration information and the uplink data is sent in the NOMA transmission mode.

Step 204: When the first RRC signaling contains the first field, the first field indicates that the OMA or NOMA transmission mode is enabled dynamically, and the terminal detects that the DCI sent by the network device is through the second RNTI When scrambling, read the scheduling information in the DCI according to the OMA configuration information and send the uplink data in the OMA transmission mode.
