[0063] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0064] In related technologies, DCI information is carried by PDCCH, where DCI information may include resource block (RB) allocation information, modulation mode, hybrid automatic repeat request (HARQ) identifier (HARQ-ID), power control information, etc. A PDCCH carries information of a DCI format, and different types of control information correspond to different DCI formats. As business demands increase, the number of DCIs that need to be carried will increase significantly, which will lead to insufficient control channel resources.

[0065] Based on this, in various embodiments of the present application, not only PDCCH is used to carry control information, but PDSCH is also used to carry control information, that is, control information is carried jointly by PDCCH and PDSCH. In this way, PDCCH resources can be used to carry more control information, so that the amount of transmission data of the control information is not limited, thereby improving the utilization rate of control channel resources.

[0066] The present application embodiment provides an information transmission method, which is applied to a terminal, such as Figure 1 As shown, the method includes:

[0067] Step 101: receiving first information, where the first information is carried on a control channel and is used to schedule a first physical downlink shared channel;

[0068] Step 102: Receive second information, where the second information is carried on the first physical downlink shared channel and is used to schedule data transmission.

[0069] In actual application, the terminal may be referred to as user equipment (UE) or a user, etc. The embodiment of the present application does not limit the name of the terminal as long as its function is realized.

[0070] In actual application, the network device may configure the first information for the terminal and send the first information to the terminal through a control channel; wherein the network device may also be called an access network device, a base station, etc., such as a fifth generation mobile communication technology (5G) base station. The embodiment of the present application does not limit the name of the network device as long as its function is realized. In addition, the control channel may be set to PDCCH.

[0071] Correspondingly, the terminal can receive the first information carried in the control channel by blindly detecting the control channel; the first information can be called first control information, first DCI, etc., and the embodiment of the present application does not limit the name of the first information.

[0072] In actual application, the first information is used to schedule the first physical downlink shared channel for the terminal; that is, the first information can be understood as control information of the first physical downlink shared channel.

[0073] Here, in actual application, in order to reduce the amount of data carried on the control channel to save control channel resources of the physical layer, basic control information of the first physical downlink shared channel may be carried in the control channel.

[0074] Specifically, in one embodiment, the first information includes at least one of the following:

[0075] Time-frequency domain information;

[0076] Modulation and coding information;

[0077] Retransmit the information.

[0078] Among them, the time-frequency domain information is used to indicate the time-frequency domain position corresponding to the scheduled first physical downlink shared channel, and the time-frequency domain information may specifically include a first identifier, and the first identifier is used to indicate the relative position of the control channel and the first physical downlink shared channel (that is, the time interval between the control channel and the first physical downlink shared channel), so that the terminal can determine the scheduled first physical downlink shared channel.

[0079] In actual application, in step 102, after determining the scheduled first physical downlink shared channel, the terminal can receive the second information sent by the network device through the first physical downlink shared channel, thereby determining the resources for data transmission scheduled for the terminal; wherein, the second information can be called second control information, second DCI, etc., and the embodiment of the present application does not limit the name of the second information.

[0080] Here, since data transmission can be divided into uplink scheduling or downlink scheduling, the network device can set a format identifier (which can be expressed as format ID in English) in the second information to indicate the scheduling type of the second information to the terminal.

[0081] Specifically, in one embodiment, the second information is at least used to indicate whether the data transmission is uplink scheduling or downlink scheduling.

[0082] The second information may include a second identifier, and the second identifier is used to indicate the scheduling type of the second information. Exemplarily, when the value of the second identifier is set to 1, it can indicate that the scheduling type of the second information is downlink scheduling, and when the value of the second identifier is set to 0, it can indicate that the scheduling type of the second information is uplink scheduling; of course, when the value of the second identifier is set to 1, it can indicate that the scheduling type of the second information is uplink scheduling, and when the value of the second identifier is set to 0, it can indicate that the scheduling type of the second information is downlink scheduling, and the embodiment of the present application does not limit this.

[0083] Here, for downlink scheduling, the network device may schedule corresponding downlink resources for the terminal through the second information.

[0084] Specifically, in one embodiment, the channel carrying data includes a second physical downlink shared channel, and the second information is at least used to indicate a relative position between the second physical downlink shared channel and the first physical downlink shared channel.

[0085] In actual application, when the channel carrying data includes the second physical downlink shared channel, the second information can be understood as control information of the second physical downlink shared channel, and the second physical downlink shared channel can be scheduled for the terminal.

[0086] In actual application, in order to enable the terminal to determine the scheduled second physical downlink shared channel, the network device can set a third identifier to indicate to the terminal the relative position of the second physical downlink shared channel and the first physical downlink shared channel; that is, the second information can include the third identifier.

[0087] For example, Figure 2 As shown, when the control channel is set to PDCCH, the network device can indicate the relative position of the PDCCH and the scheduled first PDSCH (i.e., the first physical downlink shared channel) through K0 (i.e., the first identifier) ​​in the first information; further, the relative position of the first PDSCH and the second PDSCH (i.e., the second physical downlink shared channel) can be indicated through the K3 identifier (i.e., the third identifier) ​​in the second information.

[0088] Here, in actual application, the relative position of the first physical downlink shared channel and the second physical downlink shared channel can specifically refer to the time interval between the first physical downlink shared channel and the second physical downlink shared channel; wherein, the time interval between the first physical downlink shared channel and the second physical downlink shared channel can be determined by the value of the third identifier.

[0089] For example, Figure 3 As shown, when the K3 identifier is set to 0 (k3=0), it can indicate that the first PDSCH and the second PDSCH are in the same time slot; when the K3 identifier is set to 1 (k3=1), it can indicate that the second PDSCH is in a time slot after the time slot where the first PDSCH is located; when the K3 identifier is set to 2 (k3=2), it can indicate that the second PDSCH is in two time slots after the time slot where the first PDSCH is located. The embodiments of the present application are not limited to this.

[0090] Here, for uplink scheduling, the network device may schedule corresponding uplink resources for the terminal through the second information.

[0091] Specifically, in one embodiment, the channel carrying data includes a first physical uplink shared channel, and the second information is at least used to indicate a relative position between the first physical uplink shared channel and the first physical downlink shared channel.

[0092] In actual application, when the channel carrying data includes the first physical uplink shared channel, the second information can be understood as control information of the first physical uplink shared channel, and can schedule the first physical uplink shared channel for the terminal.

[0093] In actual application, in order to enable the terminal to determine the scheduled first physical uplink shared channel, the network device can set a fourth identifier to indicate to the terminal the relative position of the first physical uplink shared channel and the first physical downlink shared channel; that is, the second information can include the fourth identifier.

[0094] Exemplarily, when the control channel is set to PDCCH, the network device can indicate the relative position of PDCCH and the scheduled first PDSCH through K0 (i.e., the first identifier) ​​in the first information; further, the relative position of the first PDSCH and the first physical uplink shared channel (PUSCH, Physical Uplink Shared CHannel) through the K4 identifier (i.e., the fourth identifier) ​​in the second information.

[0095] Here, in actual application, the relative position of the first physical downlink shared channel and the first physical uplink shared channel may specifically refer to the time interval between the first physical downlink shared channel and the first physical uplink shared channel; wherein the time interval between the first physical downlink shared channel and the second physical downlink shared channel may be determined by the value of the fourth identifier.

[0096] For example, Figure 4 As shown, when the K4 identifier is set to 0 (k4=0), it can indicate that the first PDSCH and the first PUSCH are in the same time slot; when the K4 identifier is set to 1 (k4=1), it can indicate that the first PUSCH is in a time slot after the time slot where the first PDSCH is located; when the K4 identifier is set to 2 (k4=2), it can indicate that the first PUSCH is in two time slots after the time slot where the first PDSCH is located. The embodiments of the present application are not limited to this.

[0097] In addition, with respect to uplink scheduling or downlink scheduling, the second information may further include control-related information of the uplink scheduling or downlink scheduling.

[0098] Specifically, in one embodiment, the second information includes at least one of the following:

[0099] Information about the resource;

[0100] Transport block related information;

[0101] Retransmit relevant information;

[0102] Information related to multiple antennas;

[0103] Control channel scheduling and indication related information.

[0104] Among them, the resource information may include carrier indication information, partial bandwidth (BWP, Bandwidth Part) indication information, time domain resource allocation information, frequency domain resource allocation information, virtual resource block (VRB, Virtual Resource Block) to physical resource block (PRB, Physical Resource Block) mapping related information, PRB bundling size indication information, reserved resource information, zero-power downlink channel state information reference signal (CSI-RS, Channel State Information Reference Signal) trigger indication information, transmission control protocol (TCP, Transmission Control Protocol) indication information for scheduling PUSCH, uplink (UL, Uplink) or supplementary uplink (SUL, Supplementary Uplink) indication information, frequency hopping information and downlink assignment index (DAI, Downlink Assignment Index), etc. The embodiment of the present application does not limit the specific content of the resource information.

[0105] In addition, the transmission block related information may include modulation and coding strategy (MCS), new transmission data (NDI) and redundant version (RV), etc.; the retransmission information may include HARQ process number, DAI, PDSCH to HARQ feedback timing information, code block group (CBG) based transmission information, CBG clearing information, etc.; the multi-antenna related information may include antenna port, transmission configuration indication (TCI, Transmission Configuration Index), sounding reference signal (SRS, Sounding Reference Signal) request and demodulation reference signal (DM-RS, Demodulation Reference Signal) sequence initialization and other information; the scheduling and indication related information of the control channel may include TCP indication and PUCCH resource indicator for scheduling physical uplink control channel (PUCCH, Physical Uplink Control Channel), etc. The specific content of the above information is not limited in the embodiments of the present application.

[0106] Accordingly, the embodiment of the present application also provides an information transmission method, which is applied to a network device, such as Figure 5 As shown, the method includes:

[0107] Step 501: Send first information, where the first information is carried on a control channel and is used to schedule a first physical downlink shared channel;

[0108] Step 502: Send second information, where the second information is carried on the first physical downlink shared channel and is used to schedule data transmission.

[0109] In actual application, in order to ensure the reliability of the second information carried by the first physical downlink shared channel, the network device may add a replication transmission measure to improve the reliability of data transmission, thereby ensuring that the terminal can detect the carried second information.

[0110] Based on this, in one embodiment, the method may further include:

[0111] The second information is copied to obtain N pieces of second information, where the value of N is an integer greater than 1;

[0112] N second information are sent.

[0113] In actual application, the network device can copy the second information and send the copied N second information to the terminal; in this way, even if there is information loss during the information transmission process (for example, M second information is lost, and the value of M is less than N), the terminal can successfully receive the second information. In this way, the reliability of data transmission is increased.

[0114] Exemplarily, the network device copies the second information to obtain 10 second information, and sends 10 second information to the terminal; during the information transmission process, 2 second information may be lost, and the other 8 second information can be successfully transmitted, so that the terminal can successfully receive the second information.

[0115] In addition to the copy transmission measure, the network device may also add a retransmission measure to ensure the reliability of data transmission.

[0116] Based on this, in one embodiment, the method may further include:

[0117] In the case that the third information sent by the terminal is not received, the second information is sent repeatedly, and the third information indicates that the second information is successfully received.

[0118] Here, after the network device sends the second information to the terminal, if the terminal successfully receives the second information, the third information may be fed back to the network device, so that the network device can know that the second information is successfully received by the terminal.

[0119] If the terminal fails to successfully receive the second information, the third information will not be fed back to the network device. In this case, the network device can set a preset time length to determine whether the second information is successfully received by the terminal based on the preset time length; wherein the value of the preset time length can be set as needed, such as 5 seconds.

[0120] Exemplarily, when the preset time length is set to 5 seconds, if the network device does not receive the third information sent by the terminal within the preset time length after sending the second information, it is considered that the second information has not been successfully received by the terminal. At this time, the network device may repeatedly send the second information until the third information sent by the terminal is received within the preset time length.

[0121] In the information transmission method provided in the embodiment of the present application, the terminal receives first information, the first information is carried on the control channel, and the first information is used to schedule the first physical downlink shared channel; and receives second information, the second information is carried on the first physical downlink shared channel, and the second information is used to schedule data transmission. The technical solution provided in the embodiment of the present application uses the control channel (such as PDCCH) and PDSCH to jointly carry control information, so as to reduce the limitation of the carrying capacity of control information caused by the shortage of control channel resources; that is, PDCCH is used to carry basic control information, and PDSCH is used to carry other control information. In this way, the flexibility of control information configuration can be greatly increased, thereby using control channel resources to carry more control information and increasing the transmission amount of control information.

[0122] The present application is described in further detail below in conjunction with application examples.

[0123] As business demands continue to increase, the physical layer will become more and more differentiated. Therefore, the requirements for flexible scheduling of the air interface will also increase, and the corresponding control information will inevitably increase. For example, compared with the fourth-generation mobile communication technology (4G), 5G adds control information for UE groups; for another example, since the PDCCH in the new air interface (NR, New Radio) does not necessarily span the entire carrier bandwidth, 5G adds flexible BWP indication information.

[0124] Based on this, in this application example, a flexible control information configuration scheme is proposed, which enables the network side to transmit control information through PDCCH and PDSCH to solve the problem of tight PDCCH resources and limited information carried on PDCCH.

[0125] Specifically, for downlink information, the terminal can obtain the first DCI (i.e., the first information mentioned above) of the first PDSCH carried by the PDCCH by blindly detecting the PDCCH. The first DCI may include the receiving time and frequency information of the first PDSCH (i.e., the time and frequency domain information mentioned above) (specifically including time domain resource information (expressed as Time domain resource assignment in English) and frequency domain resource information (Frequency domain resource assignment)), modulation and coding information (expressed as Modulation and coding scheme in English) at least one; through the first DCI, the second DCI carried by the first PDSCH is received, the second DCI can be understood as the control information of the second PDSCH, and the second information can include time and frequency information, MCS configuration, HARQ process number, redundant version and other information.

[0126] Here, in actual application, the terminal can decode the first PDSCH according to the first PDSCH control information (i.e., the first DCI) carried by the PDCCH; and can decode the second PDSCH according to the control information (i.e., the second DCI) carried by the first PDSCH. For the scheduled first PDSCH, the relative position with respect to the PDCCH can be indicated by K0 in the first DCI. In addition, this application example introduces the K3 identifier, and the relative position (also understood as the time interval) of the second PDSCH with respect to the first PDSCH is indicated by the K3 identifier in the second DCI; wherein, the first PDSCH and the second PDSCH can be in one time slot.

[0127] For uplink information, the terminal can obtain the first DCI of the first PDSCH carried by the first PDCCH by blindly detecting PDCCH, and the first DCI may include at least one of the receiving time-frequency information and modulation and coding information of the first PDSCH; through the first DCI, the third DCI carried by the first PDSCH is received, and the third DCI can be understood as the control information of the first PUSCH, and the third DCI may include at least one of the time-frequency information, MCS configuration, HARQ process number, and redundant version.

[0128] Here, the relative position of the first PDSCH to the PDCCH may be indicated by K0 in the first DCI. In addition, this application example introduces the K4 identifier, and for the scheduled first PUSCH, the relative position to the first PDSCH may be indicated by the K4 identifier in the second DCI.

[0129] From the above description, it can be seen that the most basic control information (such as transmission time frequency, MCS and other information) can be carried on the PDCCH, and other control information can be carried on the first PDSCH, making the physical layer data transmission method more flexible, so that a larger amount of data can be carried on the PDSCH and more control information can be accommodated, solving the problem of increased control signaling caused by increasing physical layer differentiation.

[0130] In addition, this application example also defines a DCI format m to carry the time frequency, MCS and other control information of the first PDSCH through the first PDCCH, and to carry the control information of the second PDSCH or the first PUSCH through the first PDSCH. In this way, the flexibility of the control information configuration can be increased, thereby solving the problem of scarce PDCCH resources.

[0131] In actual application, for downlink transmission, the second DCI carried by the first PDSCH is used to schedule (also called configure) the second PDSCH; for uplink transmission, the third DCI carried by the first PDSCH is used to schedule the first PUSCH. For different scheduling types, the format ID in the DCI carried by the first PDSCH can be used to indicate the scheduling type. For example, a format ID of 0 can indicate that the scheduling type is uplink scheduling, and a format ID of 1 can indicate that the scheduling type is downlink scheduling.

[0132] Here, in the case of scheduling the second PDSCH, the second DCI carried by the first PDSCH includes at least one of the following: format ID; time domain resource information; frequency domain resource information; MCS; VRB to PRB mapping (expressed as VRB-to-PRBmapping in English); new data indicator (expressed as New data indicator in English); redundancy version (expressed as Redundancy version in English); HARQ process number (expressed as HARQ process number in English); TPC indication for scheduled PUCCH (expressed as TPC command for scheduled PUCCH in English); CBGTI.

[0133] Here, in the case of scheduling the first PUSCH, the third DCI carried by the first PDSCH includes at least one of the following: format ID; time domain resource information; frequency domain resource information; MCS; frame hopping flag (expressed as Frequencyhopping flag in English); new data indication; redundant version; HARQ process number; supplementary uplink indication (expressed as TPC / SUL indicator in English); carrier indication (expressed as Carrier indicator in English).

[0134] In the application example of this application, the most basic control information is carried in the first PDCCH, and the control information of the second PDSCH or the first PUSCH is transmitted using the first PDSCH; wherein, by introducing the identifiers K3 and K4, the relative position between the first PDSCH and the second PDSCH or the first PUSCH scheduled by the first PDSCH can be indicated. In this way, the flexibility of the control information configuration can be increased, so that more control information can be transmitted through the PDCCH, solving the problem of limited information carrying capacity due to limited PDCCH resources.

[0135] In addition, in order to ensure the reliability of the DCI carried by the first PDSCH (that is, it can be the same as the DCI carried by the PDCCH), measures such as retransmission and duplicate transmission can be added to the first PDSCH to improve the reliability of data transmission and ensure that the terminal can detect the DCI carried by the first PDSCH.

[0136] In order to implement the method of the embodiment of the present application, the embodiment of the present application also provides an information transmission device, which is arranged on the terminal, such as Figure 6 As shown, the device comprises:

[0137] A first receiving unit 601 is configured to receive first information, where the first information is carried on a control channel and is used to schedule a first physical downlink shared channel;

[0138] The second receiving unit 602 is configured to receive second information, where the second information is carried on the first physical downlink shared channel and is used to schedule data transmission.

[0139] In actual application, the first receiving unit 601 and the second receiving unit 602 can be implemented by a communication interface in an information transmission device.

[0140] In order to implement the method of the embodiment of the present application, the embodiment of the present application also provides an information transmission device, which is arranged on a network device, such as Figure 7 As shown, the device comprises:

[0142] The second sending unit 702 is configured to send second information, where the second information is carried on the first physical downlink shared channel and is used to schedule data transmission.

[0144] The second information is copied to obtain N pieces of second information, where the value of N is an integer greater than 1;
