[0045] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0046] I. Narrowband Physical Downlink Control Channel (NPDCCH)

[0047] One NPDCCH is composed of 1 or 2 NCCEs, and if the NPDCCH is repeatedly transmitted, only 2 narrowband control channel elements (NCCEs) can be used.

[0048] Optionally, one NCCE occupies 6 subcarrier spacings (SCSs) in the frequency domain and 1 sub-frame in the time domain.

[0049] For NPDCCH repetition transmission, in subframe unit, only transmit in the available subframes configured by higher layer signaling. If encounter unavailable subframe, postpone, postpone also if encounter Narrowband Primary Synchronisation Signal (NPSS), Narrowband Secondary Synchronisation Signal (NSSS) and Narrowband Physical broadcast channel (NPBCH) in available subframes.

[0050] For NPDCCH repetition transmission, when DL gap is configured by higher layer, for the terminal with R_max larger than threshold, the subframes corresponding to the DL gap are regarded as invalid subframes, postpone; for the terminal with R_max smaller than threshold, do not perform gap transmission, the subframes corresponding to the DL gap are still regarded as valid subframes.

[0051] II. Downlink Control Information (DCI) format N0 (DCI format N0).

[0052] If format N0 CRC is scrambled by PUR-RNTI, the content contained in the DCI is shown in Table 1, otherwise shown in Table 2.

[0053] Table 1:

[0054] Table 2:

[0055] If the number of information bits in format N0 mapped onto the UE-specific search space given by C-RNTI defined in [3] is less than the number of information bits of format N1 in the same search space, then zeros shall be appended on format N0 until the payload size is equal to the payload size of format N1.

[0056] NPDCCH format N0 is used to schedule NPUSCH, DCI needs 23 bits, plus CRC is 39 bits;

[0057] There are 2 bits in NPDCCH format N0 to indicate the number of DCI subframe repetition (USS), corresponding to R1, R2, R3, R4 respectively, and the maximum repetition number R_max is configured to determine.

[0058] The supported repetition numbers are {1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048}, that is, R_max is taken from these repetition numbers.

[0059] When R_max >= 8, R4 = R_max, R3 = R_max / 2, R2 = R_max / 4, R1 = R_max / 8;

[0060] When R_max = 4, R3 = R_max, R2 = R_max / 2, R1 = R_max / 4;

[0061] When R_max = 2, R2 = R_max, R1 = R_max / 2;

[0062] When R_max = 1, R1 = R_max.

[0063] For format N2, which is a DL grant used to schedule paging, 3 bits are used to indicate the number of DCI subframe repetition (CSS), the principle is the same as above, only R1~R4 becomes R1~R8.

[0064] Three, DCI format N1.

[0065] If format N1 is used for a random access procedure initiated by a NPDCCH order, only when the NPDCCH order indicator is set to "1" and the format N1 CRC is scrambled with a cell radio network temporary identity (Cell-RNTI, C-RNTI), the content contained in the DCI is as shown in Table Three; if the format N1 CRC is scrambled with a C-RNTI or a PUR-RNTI, the content contained in the DCI is as shown in Table Four; if the format N1 CRC is scrambled with a Random Access RNTI (RA-RNTI), the content contained in the DCI is as shown in Table Five; if the format N1 CRC is scrambled with a Group RNTI (G-RNTI), the content contained in the DCI is as shown in Table Six.

[0066] Table Three:

[0067] Table Four:

[0068] Table Five:

[0069] Table Six:

[0070] If the number of information bits in format N1 mapped to the same search space is less than that of format N0, and the format N1 CRC is not scrambled by G-RNTI, then zeros should be appended on format N1 until the payload size equals that of format N0.

[0071] Four, DCI format N2.

[0072] If format N2 is used for paging: format N2 CRC is scrambled with Paging RNTI (P-RNTI) and Flag = 0, the content contained in the DCI is shown in Table Seven; if format N2 is used for paging: format N2 CRC is scrambled with P-RNTI, Flag = 1, the content contained in the DCI is shown in Table Eight; if format N2 is used to notify Single Cell Multicast Control Channel (SC-MCCH) change: format N2 CRC is scrambled with SC-RNTI, the content contained in the DCI is shown in Table Nine.

[0073] Table Seven:

[0074] Table Eight:

[0075] Table Nine:

[0076] Five, RNTI value range.

[0077] The RNTI value is shown in Table Ten.

[0078] Table Ten:

[0079] Note 1: the same C-RNTI is used by the Media Access Control (MAC) entity on all serving cells.

[0080] Note 2: SI-RNTI value FFFF can be used for MBMS dedicated carrier. SI-RNTI value FFF9 is used for Multimedia Broadcast Multicast Service (MBMS) dedicated carrier only.

[0081] Note 3: Applicable for NB-IoT.

[0082] As can be seen, for NB-IoT, the value range of RNTI is 901-FFF3. In addition, values FFF4-FFF8 can also be used for new application scenarios.

[0083] As can be seen from the above background, in the related art NB-IoT technology, the dynamic scheduling of uplink and downlink transmission is decoupled scheduling, and at least one of the periodic or semi-persistent uplink and downlink transmission cannot be triggered, except for the semi-persistent scheduling (SPS) for uplink buffer status report (BSR). In the NB-IoT scenario, voice service is supported, and from the perspective of physical layer transmission, voice service has persistence and uplink and downlink interaction. If at least one of the dynamic scheduling uplink and downlink transmission is used for each voice packet, a large amount of scheduling signaling overhead will be brought, the time-frequency resources are occupied, the available time-frequency resources of uplink and downlink are reduced, and the call quality is reduced. In addition, frequent scheduling signaling transmission will also cause time delay to increase, affecting the call experience. Further, the voice packet has regularity, and the voice packet size also does not change greatly in a short time, and therefore the physical layer transmission parameter is relatively stable and does not change frequently. Therefore, the introduction of semi-persistent transmission of joint scheduling uplink and downlink can well cope with this scenario, reduce unnecessary redundant signaling overhead, improve transmission efficiency, and improve call quality. Therefore, the joint transmission processing method is proposed.

[0084] The joint transmission processing method provided by the embodiments of the present application will be described in detail in combination with some embodiments and application scenarios and the accompanying drawings.

[0085] Referring to FIG. 2, the joint transmission processing method provided by the embodiments of the present application includes:

[0086] Step 201, receiving target information from a network side device by a terminal;

[0087] Step 202, performing transmission operation of target transmission by the terminal based on the target information, the target transmission including uplink semi-persistent scheduling (SPS) transmission and downlink SPS transmission;

[0088] The target information includes a first target DCI or a first configuration, the first target DCI is used to activate the target transmission, and the first configuration is an SPS transmission configuration of the target transmission.

[0089] In the embodiment of the application, the target transmission can be understood as a joint transmission of uplink SPS transmission and downlink SPS transmission. In one joint transmission process (in an SPS period), the uplink SPS transmission can be located before the downlink SPS transmission or after the downlink SPS transmission, which is not limited herein.

[0090] Optionally, in an embodiment, the network side device can configure the SPS transmission configuration of the target transmission for the terminal through the first configuration, so that the terminal can perform the transmission operation of the target transmission based on the first configuration. In this way, since the configuration of the target transmission is controlled by the first configuration and the transmission operation of the target transmission is performed, the signaling overhead of the target transmission can be saved.

[0091] Optionally, in an embodiment, the network side device can activate the target transmission through the first target DCI, and the terminal can activate the target transmission and perform the transmission operation of the target transmission upon receiving the first target DCI. In this way, since the target transmission is activated by the first target DCI and the transmission operation of the target transmission is performed, the signaling overhead of the target transmission can be saved.

[0092] Optionally, in the case that the target information is the first target DCI, the terminal receiving the target information from the network side device can be understood or replaced as the terminal monitoring the first target DCI, and the terminal can demodulate the first target DCI after monitoring the first target DCI.

[0093] It should be understood that after the terminal successfully demodulates the first target DCI, the terminal can transmit acknowledgment (ACK) information on the corresponding feedback resource to identify the successful reception of the first target DCI, and then perform the first target transmission according to the information carried in the first target DCI. If the demodulation is not successful, the network side device will retransmit the first target DCI without receiving the ACK information within a certain time.

[0094] Optionally, the network side device can receive the uplink SPS transmission according to the transmission indicated in the first target DCI, and if the uplink SPS transmission is not received within a first time duration, the network side device will retransmit the first target DCI. The first time duration can be a value pre-defined by a protocol or configured by the network side device, or determined according to a timing offset between the downlink SPS transmission and the uplink SPS transmission.

[0095] Optionally, the first duration starts from the transmission of the first target DCI. The first duration can be defined as a maximum time limit, or a minimum time limit, or a certain specific transmission resource, or a time window or a timer for monitoring ACK. In other words, from the perspective of the terminal, if the first target DCI is not successfully demodulated, that is, the ACK message is not sent within a certain time, the terminal will continue to monitor the first target DCI or the terminal expects to continue to receive the first target DCI after the certain time.

[0096] Optionally, the network side device can send a downlink SPS transmission according to the transmission indicated in the first target DCI. If feedback information of the terminal for the downlink SPS transmission is not received within a second duration, or negative acknowledgment (NACK) information of the terminal for the downlink SPS transmission is received, the network side device will retransmit the first target DCI. It should be noted that no matter whether the HARQ feedback of the HARQ process corresponding to the downlink SPS transmission is enabled or disabled, the terminal needs to perform HARQ-ACK feedback for the first received downlink SPS transmission. If the network side device receives NACK, the network stops sending the downlink SPS transmission and retransmits the first target DCI.

[0097] Optionally, the second duration is a value pre-defined by a protocol or configured by the network side device. The second duration starts from the transmission of the first target DCI.

[0098] Optionally, the transmission operation of the terminal for the target transmission can be understood as that the terminal sends uplink SPS transmission and the terminal receives downlink SPS transmission.

[0099] Embodiments of the present application receive target information from a network side device by a terminal; the terminal performs a transmission operation of a target transmission based on the target information, the target transmission including uplink semi-persistent scheduling (SPS) transmission and downlink SPS transmission; wherein the target information includes a first target DCI or a first configuration, the first target DCI is used to activate the target transmission, and the first configuration is an SPS transmission configuration of the target transmission. In this way, the transmission operation of the target transmission is controlled through the first target DCI or the first configuration, thereby reducing the signaling overhead of transmission.

[0100] Optionally, in some embodiments, after the terminal performs the transmission operation of the target transmission based on the target information, the method further includes:

[0101] The terminal monitors a second target DCI, the second target DCI being used to deactivate the target transmission.

[0102] In the embodiments of the present application, the network side device can deactivate the target transmission through the second target DCI, and the terminal can deactivate the target transmission and stop the transmission operation of the target transmission upon receiving the second target DCI. In this way, since the target transmission is deactivated through the second target DCI and the transmission operation of the target transmission is stopped, the signaling overhead of the target transmission deactivation management can be saved.

[0103] Optionally, in some embodiments, the terminal monitoring the second target DCI comprises:

[0104] The terminal monitors the second target DCI according to a target period.

[0105] The target period is configured or indicated by the network side device.

[0106] In the embodiments of the present application, the network side device can configure or indicate the target period for the terminal, and then the terminal periodically monitors the second target DCI based on the configured or indicated target period, so that the power consumption of monitoring the second target DCI can be reduced.

[0107] Optionally, in some embodiments, the starting moment of monitoring the second target DCI satisfies any one of the following conditions:

[0108] The starting moment of monitoring the second target DCI is the end moment of the time unit in which the first target DCI is received, or the starting moment of monitoring the second target DCI is located after the end moment of the time unit in which the first target DCI is received, and is separated from the end moment of the time unit in which the first target DCI is received by a first time length.

[0109] The starting moment of monitoring the second target DCI is determined based on a target parameter in the transmission parameter configuration of the target transmission, and the target parameter comprises at least one of a maximum transmission time, a minimum transmission time, a maximum transmission number and a minimum transmission number.

[0110] In the embodiments of the present application, the above-mentioned time unit can be a time slot, a sub-time slot, a frame, a sub-frame, etc., which is not limited further herein.

[0111] Optionally, the above-mentioned first time length can be indicated by a protocol or the network side device, for example, 0ms or 13ms or other values, which is not limited further herein.

[0112] Optionally, the starting moment of monitoring the second target DCI is determined based on a target parameter in the transmission parameter configuration of the target transmission, which can be understood as that the starting moment of monitoring the second target DCI is determined based on an ending moment n of the target transmission, wherein the ending moment n of the target transmission is determined based on the target parameter. For example, the starting moment of monitoring the second target DCI is the ending moment n of the target transmission, or the starting moment of monitoring the second target DCI is located after the ending moment n of the target transmission, and is separated from the starting moment of monitoring the second target DCI being the ending moment n of the target transmission by a second time length, which can be indicated by a protocol or a network side device, for example, 0 ms or 13 ms or other values, which are not limited herein.

[0113] Optionally, in some embodiments, the second target DCI includes at least one of the following fields:

[0114] DCI format identifier;

[0115] deactivation indication;

[0116] SPS process identifier;

[0117] Hybrid Automatic Repeat Request (HARQ) feedback resource indication;

[0118] orthogonal cover code (OCC) index.

[0119] In the embodiments of the present application, the field (or indication field) of the DCI format identifier can carry a format N0 and format N1 differentiation flag, which is used to distinguish between DCI format N0 and DCI format N1.

[0120] Optionally, the field of the deactivation indication can carry deactivation indication information, specifically, which can be indicated by N bits, or implicitly indicated by other information, for example, implicitly indicated by RNTI information. Further, the activation or deactivation can be distinguished by different RNTIs, or can be the same RNTI name but with different value ranges; or there can be an association relationship, such as complementary values. At this time, such a field in the DCI can not be needed to specially distinguish the activation or deactivation.

[0121] Optionally, a field of SPS process ID is used to identify the SPS configuration; it is to be understood that the SPS process ID here can include DL SPS process ID and UL SPS process ID, or the same process ID is used for joint configuration of DL and UL, i.e. joint SPS process ID.

[0122] Optionally, for the field of HARQ feedback resource indication, if a gap is indicated, the gap can include at least one of the following:

[0123] A gap between the HARQ feedback resource and the NPDSCH ending subframe;

[0124] A gap between the HARQ feedback resource and the SPS interval resource ending subframe;

[0125] A gap between the HARQ feedback resource and the NPDCCH.

[0126] Optionally, for the field of OCC index, the OCC index used by the current terminal is indicated to determine the OCC code for the target transmission using OCC.

[0127] Optionally, in some embodiments, the first target DCI or the second target DCI includes any of the following:

[0128] A first DCI associated with the uplink SPS transmission and a second DCI associated with the downlink SPS transmission;

[0129] A third DCI associated with the uplink SPS transmission and the downlink SPS transmission.

[0130] In the embodiments of the present application, the first target DCI and the second target DCI can be understood as DCIs of the same type, wherein the first target DCI and the second target DCI include a first DCI associated with the uplink SPS transmission and a second DCI associated with the downlink SPS transmission. It can be understood that the DL SPS transmission and the UL SPS transmission are respectively scheduled (including activation or deactivation) by the two DCIs, but there is an association relationship between the two DCIs, or there is an association relationship between the DL SPS transmission and the UL SPS transmission. For example, in some embodiments, the first DCI carries an SPS process identifier of the uplink SPS transmission, the second DCI carries an SPS process identifier of the downlink SPS transmission, and the SPS process identifier carried by the first DCI and the SPS process identifier carried by the second DCI are the same or determine the association relationship between the DL SPS process identifier and the UL SPS process identifier through target configuration. Because they are respectively scheduled, the flexibility of scheduling can be improved.
