Description

[0001] This application is a divisional application of the Chinese patent application with application number "201710453143.1", application date "June 15, 2017", and title "Information Transmission Method and Device, Storage Medium and Processor". Technical Field

[0002] The present invention relates to the field of communications, and in particular to an information transmission method and device, a storage medium and a processor. Background Art

[0003] With the continuous advancement of radio technology, various radio services have emerged in large numbers. However, the spectrum resources that radio services rely on are limited. Faced with the increasing demand for bandwidth, the spectrum resources between 300MHz and 3GHz mainly used in traditional commercial communications are extremely tight and can no longer meet the needs of future wireless communications.

[0004] In future wireless communications, higher carrier frequencies than those used by the fourth generation (4G) communication system will be used for communication, such as 28 GHz, 45 GHz, etc. This high-frequency channel has the disadvantages of large free propagation loss, easy absorption by oxygen, and large influence of rain attenuation, which seriously affects the coverage performance of the high-frequency communication system. In order to ensure that the high-frequency communication and the Long Time Evolution (LTE) system have similar signal to interference plus noise ratio (SINR) within the coverage range, it is necessary to ensure the antenna gain of the high-frequency communication. Fortunately, since the carrier frequency corresponding to the high-frequency communication has a shorter wavelength, it can be guaranteed that more antenna elements can be accommodated per unit area, and more antenna elements mean that the beamforming method can be used to improve the antenna gain, thereby ensuring the coverage performance of the high-frequency communication.

[0005] After adopting the beamforming method, the transmitter can concentrate the transmission energy in a certain direction, while the energy in other directions is very small or no. In other words, each beam has its own directionality, and each beam can only cover the terminals in a certain direction. The transmitter, i.e. the base station, needs to transmit multiple beams to achieve full coverage. Typically, the number of beams is dozens or even hundreds. In order to meet the access needs of terminals that may appear in all directions, it is necessary to achieve full coverage of system broadcast messages. Communication sites need to repeatedly send the same system broadcast message in each beam direction. For communication sites, there is also the problem of increasing the "absolute overhead" of system broadcast messages.

[0006] In the new generation of wireless communication systems (New Radio, referred to as NR), system information is divided into minimum system information (minimum SI) and other system information (other SI). Among them, the minimum system information is further divided into the "main system information (MIB)" carried on the physical broadcast channel (Physical Broadcast Channel, referred to as PBCH), and the "remaining minimum system information (Remaining Minimum SI, referred to as RMSI)" carried on the physical downlink shared channel; the main system information is used to provide basic system parameters of the cell, and the remaining minimum system information is used to provide initial access-related configuration information, such as the sending configuration of the initial access request, the receiving configuration of the initial access response message, etc. Other system information that needs to be broadcast is called other system information. Different from the existing system (such as the LTE system), in order to better forward compatibility and enhance resource scheduling flexibility in the new generation system, it is necessary to reduce the sending of always online information as much as possible. Therefore, the minimum system information is broadcasted in a periodic manner, while other system information is sent on demand.

[0007] However, there is currently no feasible technical solution for how to request and transmit other system information. Summary of the invention

[0051] The present application embodiment can be run on Figure 1 In the network architecture shown in Figure 1 As shown, the network architecture includes: A, B, C, where A, B, C (describe the functions and interactive relationships of ABC)

[0052] In this embodiment, a method for information transmission running on a network architecture is provided. Figure 2 The process of the information transmission method according to the embodiment of the present invention is as follows Figure 1 ,like Figure 2 As shown, the process includes the following steps:

[0053] Step S202, the network side sends request configuration information of other system information to the terminal; wherein the request configuration information of other system information includes: sending configuration of request information of other system information; the request information of other system information is information sent to the network side when the terminal requests to obtain other system information;

[0054] Step S204: The network side sends other system information on the downlink transmission port indicated by the request information of other system information.

[0055] Through the above steps S202-204, the network side sends request configuration information of other system information to the terminal; wherein the request configuration information of other system information includes: sending configuration of request information of other system information; the request information of other system information is information sent to the network side when the terminal requests to obtain other system information, and then the network side sends other system information on the downlink transmission port indicated by the request information of other system information; it can be seen that through the above steps, the network side can effectively transmit other system information to the terminal side, filling the gap in the relevant technology and solving the problem of how to transmit other system information that has not yet existed in the relevant technology.

[0056] Optionally, the execution entity of the above steps on the network side may be a base station or other network elements, but is not limited thereto.

[0057] Optionally, the execution order of step S202 and step S204 can be interchanged, that is, step S204 can be executed first, and then step S202.

[0058] It should be noted that the request configuration information of other system information involved in this embodiment is configured through the remaining minimized system information, or through the dedicated radio resource control RRC signaling configuration.

[0059] In addition, the request information of other system information in this embodiment is a preamble sequence transmitted in one or more preamble resources predefined by the system; wherein the preamble resources include at least one of the following time domain, frequency domain, and code domain resources. Therefore, when other system information is divided into one or more categories, one preamble resource corresponds to one category of other system information.

[0060] Optionally, the method of this embodiment may further include:

[0061] Step S206: The network side identifies the downlink transmission port and the type of other system information requested by the terminal in the request information of other system information.

[0062] In addition, in another optional implementation of the present embodiment, the request configuration information of other system information involved in the present embodiment also includes at least one of the following: transmission period of various types of other system information, transmission time window of other system information, frequency domain position of other system information, transmission resource information of other system information, whether other system information has been transmitted on the transmission resources, and the type of other system information that has been transmitted.

[0063] Based on the request configuration information of the above-mentioned other system information, the way in which the network side sends other system information on the downlink transmission port indicated by the request information of other system information in step S204 of this embodiment can be in a specific application scenario: the network side sends other system information to the terminal through the downlink transmission port indicated by the request information of other system information according to the transmission period, time window, and frequency domain position of other system information.

[0064] In another optional implementation of this embodiment, the request configuration information of other system information involved in this embodiment also includes: random access response RAR reception configuration. Based on this, step S202 involved in this embodiment: the network side sends the request configuration information of other system information to the terminal, in a specific application scenario, can be: the network side includes the other system information in the random access response RAR and sends it.

[0065] The random access response includes at least one of the following: a transmission period of other system information, a transmission time window of other system information, a frequency domain position of other system information, transmission resource information of other system information, and a type of other system information that has been transmitted.

[0066] Based on the random access response, the method of this embodiment may further include: the network side sends other system information according to a transmission period of other system information, a transmission time window of other system information, and a frequency domain position of other system information.

[0067] The present embodiment is described below in conjunction with specific implementation methods; Specific implementation method 1

[0069] Indicate other SI in RMSI to request preamble to send configuration; after the terminal obtains the configuration information in RMSI, it sends the preamble corresponding to the expected other SI; receive RAR, and obtain the requested other SI in RAR.

[0070] Implementation 1 will be specifically described below with reference to Implementation 1.1 and Implementation 1.2.

[0071] exist Specific implementation 1.1 The process steps include:

[0072] Step S1: gNB sends request configuration information of other system information to UE1;

[0073] Step S2: UE1 feeds back preamble to gNB;

[0074] Step S3: gNB sends a RAR carrying other system information to UE1.

[0075] The above steps S1 to S3 are described in detail as follows: the gNB indicates other system information (other SI) request configuration information to the terminal through the remaining minimized system information RMSI; in this embodiment, the terminal needs to request other SI from the base station by sending a random access request preamble sequence (preamble); therefore, the other system information (other SI) request configuration information includes the sending configuration of the preamble, Figure 3 The sending configuration diagram of the request configuration information of other system information according to the embodiment of the present invention includes a preamble Figure 1 ,like Figure 3 As shown, since the high-frequency band RMSI needs to be transmitted in a beam manner, that is, to complete full coverage of the expected coverage range, it needs to be transmitted in different beam directions. When the terminal requests other system information, it needs to indicate to the base station which downlink transmission beam (or port) it is in, so that the base station can send the other system information in the beam direction (or port) where the terminal is located. In this embodiment, assuming that the reciprocity of the terminal and the base station side is established, the port for sending the RMSI downlink uniquely corresponds to a preamble time-frequency domain resource, that is, the terminal sends the preamble on the preamble time-frequency domain resource corresponding to the RMSI, and the base station can determine the downlink beam (or port) where the current terminal is located. For example, if the terminal receives RMSI on beam2, then according to the RMSI configuration in beam 2, it is known that the corresponding preamble resource is preamble resource 2, and the terminal will send the preamble on preamble resource 2. Correspondingly, if the base station receives the preamble on preamble resource 2, it is determined that the UE under beam2 needs other SI, and the subsequent base station will send other SI on beam2.

[0076] In addition, other SI is pre-divided into two categories by the system: for example, SI related to neighboring cell measurement is the first category of other system information; the remaining other system information is the second category of other system information. And two preamble sequence resources are predefined specifically for other SI application, sequence 1 corresponds to the first category of other system information, and sequence 2 corresponds to the second category of other system information. At this time, if the terminal wants to request other system information related to neighboring cell measurement, the terminal will choose to send sequence 1.

[0077] Furthermore, Figure 4 is a schematic diagram of other system information carried on RAR according to an embodiment of the present invention, such as Figure 4 As shown, the base station receives the other SI request dedicated preamble sequence 1 sent by the terminal on preamble resource 2, then the base station determines that only the other SI related to the neighboring cell measurement is included in the RAR corresponding to beam2.

[0078] The terminal that has sent the other SI request information receives the RAR according to the RAR reception configuration configured on the network side, and obtains the desired other SI in the RAR.

[0079] When receiving RAR, the terminal blindly detects DCI with RA-RNTI in the search space of the physical downlink control channel (PDCCH) of the corresponding time slot, obtains the scheduling information of the random access response information in DCI, and receives the random access response information according to the scheduling information, and then obtains the other SI contained in the random access response information. Specific implementation 1.2

[0081] Figure 5 The sending configuration diagram of the request configuration information of other system information according to the embodiment of the present invention includes a preamble Figure 2 ,like Figure 5 As shown in the figure, when the reciprocity on the base station side does not hold and the reciprocity on the UE side holds, that is, the downlink transmit port (beam) on the base station side cannot uniquely correspond to the uplink receive port (beam) on the base station side, and the downlink receive port (beam) on the terminal side uniquely corresponds to the uplink transmit port (beam). At this time, there will be multiple preamble transmission time-frequency resources corresponding to the downlink transmit beam beam2, so that the base station can receive the preamble transmission of the terminal with different receive ports. That is, the base station switches the receive port (beam direction) on multiple preamble transmission time-frequency resources, and the transmit port (beam) of the terminal remains unchanged, that is, polling of the receive port on the base station side is performed.

[0082] When reciprocity does not hold on the UE side, but reciprocity holds on the base station side, that is, the downlink receiving port (beam) on the terminal side cannot uniquely correspond to the uplink transmitting port (beam), while the downlink transmitting port (beam) on the base station side uniquely corresponds to the uplink receiving port (beam) on the base station side. At this time, when the UE sends the preamble, it needs to repeatedly send the preamble through multiple uplink transmitting ports (beams) to ensure that the base station side can receive it. In this case, it is also necessary to define multiple corresponding preamble transmission time-frequency resources for a downlink transmitting port (beam). On different preamble transmission time-frequency resources, the terminal will change the transmitting port (beam), while the receiving port (beam) on the base station side remains unchanged, that is, polling the transmitting port on the terminal side is performed.

[0083] In another case, the reciprocity on both the UE side and the base station side does not hold. In this case, it is necessary to define more preamble transmission time-frequency resources and a downlink transmit port (beam), that is, to complete the joint polling of the terminal side transmit port (beam) and the base station side receive port (beam) according to certain rules. For example, the base station side receive port is polled first, that is, the base station side receive port (beam) is switched on multiple consecutive preamble resources, and the terminal keeps the transmit port (beam) unchanged; after the base station receive port is polled once, the terminal switches to another transmit port (beam), and the base station polls for reception; this is repeated to complete any combination of transmission of all the terminal transmit ports and the base station side receive ports.

[0084] It should be noted that in the above-mentioned cases, the defined set of preamble transmission time-frequency resources corresponds to a certain downlink transmission port, that is, when the base station receives the other SI request preamble sent by the terminal on any of these resources, the base station can determine the downlink transmission port (beam direction) where the UE is located, and send the other SI on the corresponding port. Specific implementation method 2

[0086] The specific implementation method 2 is as follows: RMSI or RRC dedicated signaling indicates the configuration of sending other SI request information, as well as the period, transmission time window, and frequency domain position of various types of other SI; after the terminal obtains the configuration information in RMSI, it sends the preamble corresponding to the expected other SI. Blind detection of PDCCH within the specified time window.

[0087] In a specific embodiment, the method includes the following steps:

[0088] Step S1: gNB sends request configuration information of other system information to UE1;

[0089] Step S2: UE1 feeds back preamble to gNB;

[0090] Step S3: gNB sends a physical downlink shared channel (PDSCH) carrying other system information to UE1.

[0091] For S1-S3 in this specific embodiment, the base station gNB sends other system information (other SI) request configuration information to the terminal; wherein the other system information (other SI) request configuration information includes: the sending configuration of the request information of other system information, and the transmission period, time window, and frequency domain position of other SI, wherein the request information of other system information refers to the information sent to the network side when the terminal requests to obtain other system information.

[0092] Specifically, the gNB indicates other system information (otherSI) request configuration information to the terminal through the remaining minimized system information (RMSI); in this embodiment, the terminal needs to request other SI from the base station by sending a random access request preamble sequence (preamble); therefore, the other system information (other SI) request configuration information includes the sending configuration of the preamble, such as Figure 3 As shown, since the high-frequency band RMSI needs to be transmitted in a beam manner, that is, to complete full coverage of the expected coverage range, it needs to be transmitted in different beam directions. When the terminal requests other system information, it needs to indicate to the base station which downlink transmission beam (or port) it is in, so that the base station can send the other system information in the beam direction (or port) where the terminal is located. In this embodiment, assuming that the reciprocity of the terminal and the base station side is established, the port for sending the RMSI downlink uniquely corresponds to a preamble time-frequency domain resource, that is, the terminal sends the preamble on the preamble time-frequency domain resource corresponding to the RMSI, and the base station can determine the downlink beam (or port) where the current terminal is located. For example, if the terminal receives RMSI on beam2, then according to the RMSI configuration in beam 2, it is known that the corresponding preamble resource is preamble resource2, and the terminal will send the preamble on preamble resource 2. Correspondingly, if the base station receives the preamble on preamble resource2, it is determined that the UE under beam2 needs other SI, and the subsequent base station will send other SI on beam2.

[0093] In addition, other SI is pre-divided into multiple types by the system: each type of other system information corresponds to a dedicated preamble sequence, and the terminal and the base station are aware of the division method of the above other system information and the corresponding relationship between each type of other system information and the dedicated preamble sequence. At this time, if the terminal wants to request a certain type of other system information, the terminal will choose to send the preamble sequence corresponding to this type of other system information.

[0094] Furthermore, Figure 6 FIG. 1 is a schematic diagram of other system information carried on a physical downlink shared channel according to an embodiment of the present invention. Figure 6 As shown, when the subordinate terminal has other SI acquisition requirements, the base station will transmit according to the predefined other SI cycle and within a fixed transmission time window; the other SI transmission time window includes one or more time slots.

[0095] The terminal obtains the transmission period of other SI in RMSI (for example, the transmission period is 160ms), transmission time window (the transmission time window can be at the radio frame level, for example, the transmission time window is represented by the system frame number (SFN): SFN mod16=1 or 2, indicating that two consecutive radio frames with the system frame number modulo 16 of 1 or 2 are one transmission time window; further, the transmission time window can also be a subframe granularity, and it is necessary to further indicate which subframes are included in the transmission time window based on the system frame number), and frequency domain position. In the specified frequency domain position and each slot of the transmission time window, the terminal uses SI-RNTI to blindly detect the downlink control information (DCI) in the physical downlink control channel (PDCCH), thereby determining whether the physical downlink shared channel (PDSCH) in this slot carries the other SI requested by the terminal. The terminal will obtain other SI in a slot within the other SI transmission time window.

[0096] When there are multiple downlink transmission ports (beams) and terminals requesting other SI, the base station will transmit other SI on multiple downlink transmission ports (beams) with other SI transmission requirements, and the base station can flexibly determine which slot to use to transmit other SI of which port (beam). In addition, different terminals can request different types of other SI, so the types of other SI carried in the slots corresponding to different ports (beams) can also be different.

[0097] In this embodiment, it is assumed that reciprocity is established on both the terminal and base station sides. Similar to Embodiment 2, when reciprocity is not established on one side or both sides, more preamble resources will be configured to correspond to the downlink transmission port (beam) to complete the port (beam) polling transmission on one side or both sides. Specific implementation method 3

[0099] This specific implementation method indicates the other SI request information sending configuration in RMSI or RRC dedicated signaling, as well as the period, transmission time window, and frequency domain position of various other SIs; after the terminal obtains the configuration information in RMSI, it sends the preamble corresponding to the expected other SI. Blind detection of PDCCH within the specified time window.

[0100] The difference from specific implementation method 2 is that the other system information (other SI) request configuration information sent by the base station gNB to the terminal includes: the sending configuration of the request information of other system information, and the transmission resource configuration information of other SI (such as frequency domain position, specific slot information in the time domain). Figure 7 The sending configuration diagram of the request configuration information of other system information according to the embodiment of the present invention includes a preamble Figure 3 ,like Figure 7 As shown, in RMSI, the preamble resources corresponding to the downlink port (beam) where the RMSI is located and the subsequent transmission resources of other SI are directly configured. At this time, the terminal does not need to determine whether other SI is included by blindly detecting the downlink control information in each slot within the transmission time window, but directly blindly detects DCI in the specified slot, and obtains the scheduling information of other SI in PDSCH in DCI, and receives other SI according to the scheduling information.

[0101] It should be noted that in this way, the other SI transmission resources notified in the RMSI are only pre-configured resources. When a corresponding terminal requests other SI, the requested other SI is sent using the pre-configured resources; if no terminal requests other SI on certain downlink ports (beams), the pre-configured other SI resources will be used to send other information without the need for reservation. Specific implementation method 4

[0103] The specific implementation method 4 is: RMSI or RRC dedicated signaling indicates other SI request information sending configuration and other SI transmission resource configuration information; after the terminal obtains the configuration information in RMSI, it sends the preamble corresponding to the expected other SI. Blind detection of downlink control information on the specified other transmission resource.

[0104] In this specific embodiment 4, the method steps include:

[0105] Step S1: gNB sends request configuration information of other system information to UE1;

[0106] Step S2: UE1 feeds back preamble to gNB;

[0107] Step S3: gNB sends RAR to UE1.

[0108] Step S4: gNB sends a PDSCH carrying other system information to UE1.

[0109] For the above steps S1-S4, specifically, it can be: the base station gNB sends other system information (otherSI) request configuration information to the terminal; wherein, the other system information (other SI) request configuration information includes: the sending configuration of the request information of other system information, and the random access response receiving configuration, wherein, the request information of other system information refers to the information sent to the network side when the terminal requests to obtain other system information.

[0110] Specifically, the gNB indicates other system information (otherSI) request configuration information to the terminal through the remaining minimized system information (RMSI); in this embodiment, the terminal needs to request other SI from the base station by sending a random access request preamble sequence (preamble); therefore, the other system information (other SI) request configuration information includes the sending configuration of the preamble, such as Figure 3As shown, since the high-frequency band RMSI needs to be transmitted in a beam manner, that is, to complete full coverage of the expected coverage range, it needs to be transmitted in different beam directions. When the terminal requests other system information, it needs to indicate to the base station which downlink transmission beam (or port) it is in, so that the base station can send the other system information in the beam direction (or port) where the terminal is located. In this embodiment, assuming that the reciprocity of the terminal and the base station side is established, the port for sending the RMSI downlink uniquely corresponds to a preamble time-frequency domain resource, that is, the terminal sends the preamble on the preamble time-frequency domain resource corresponding to the RMSI, and the base station can determine the downlink beam (or port) where the current terminal is located. For example, if the terminal receives RMSI on beam2, then according to the RMSI configuration in beam 2, it is known that the corresponding preamble resource is preamble resource2, and the terminal will send the preamble on preamble resource 2. Correspondingly, if the base station receives the preamble on preamble resource2, it is determined that the UE under beam2 needs other SI, and the subsequent base station will send other SI on beam2.

[0111] In addition, other SI is pre-divided into multiple types by the system: each type of other system information corresponds to a dedicated preamble sequence, and the terminal and the base station are aware of the division method of the above other system information and the corresponding relationship between each type of other system information and the dedicated preamble sequence. At this time, if the terminal wants to request a certain type of other system information, the terminal will choose to send the preamble sequence corresponding to this type of other system information.

[0112] The base station determines which other SIs need to be transmitted on which downlink transmission ports (beams) based on the received preamble sequence. The base station can further determine the resources for sending these other SIs, including the transmission period, time window, and frequency domain position of the other SIs, and include this information in the random access response (RAR) and feed it back to the terminal. The other SIs are sent according to the resource configuration of the other SIs.

[0113] The terminal that has sent the other SI request first receives the RAR to determine the resource configuration of the other SI. Furthermore, in this embodiment, other system information is carried on the physical downlink shared channel; specifically, the other SI transmission time window contains one or more time slots of the terminal. According to the transmission period, time window, and frequency domain position of the other SI obtained in the RAR, the terminal uses SI-RNTI in the physical downlink control channel (PDCCH) in the specified frequency domain position and each slot of the transmission time window to blindly detect the downlink control information (DCI), thereby determining whether the physical downlink shared channel (PDSCH) in this slot carries the other SI requested by the terminal. The terminal will obtain other SI in a slot within the other SI transmission time window.

[0114] When there are multiple downlink transmission ports (beams) and terminals requesting other SI, the base station will transmit other SI on multiple downlink transmission ports (beams) with other SI transmission requirements, and the base station can flexibly determine which slot to use to transmit other SI of which port (beam). In addition, different terminals can request different types of other SI, so the types of other SI carried in the slots corresponding to different ports (beams) can also be different.

[0115] In this embodiment, it is assumed that reciprocity is established on both the terminal and base station sides. Similar to Embodiment 2, when reciprocity is not established on one side or both sides, more preamble resources will be configured to correspond to the downlink transmission port (beam) to complete the port (beam) polling transmission on one side or both sides. Specific implementation method 5

[0117] The specific implementation mode 5 is as follows: RMSI indicates that other SI requests preamble transmission configuration; after the terminal obtains the configuration information in RMSI, it sends the preamble corresponding to the expected other SI. Receive RAR, obtain the period, transmission time window, and frequency domain position of various other SI in RAR; blindly detect PDCCH within the specified time window.

[0118] In this specific embodiment 5, the method steps include:

[0119] Step S1: gNB sends request configuration information of other system information to UE1;

[0120] Step S2: UE1 feeds back preamble to gNB;

[0121] Step S3: gNB sends RAR to UE1.

[0122] Step S4: gNB sends a PDSCH carrying other system information to UE1.

[0123] For the above steps S1 to S4, the base station gNB sends other system information (other SI) request configuration information to the terminal; wherein the other system information (other SI) request configuration information includes: the sending configuration of the request information of other system information, and the random access response receiving configuration, wherein the request information of other system information refers to the information sent to the network side when the terminal requests to obtain other system information.

[0124] Specifically, the gNB indicates other system information (otherSI) request configuration information to the terminal through the remaining minimized system information (RMSI); in this embodiment, the terminal needs to request other SI from the base station by sending a random access request preamble sequence (preamble); therefore, the other system information (other SI) request configuration information includes the sending configuration of the preamble, such as Figure 3 As shown, since the high-frequency band RMSI needs to be transmitted in a beam manner, that is, to complete full coverage of the expected coverage range, it needs to be transmitted in different beam directions. When the terminal requests other system information, it needs to indicate to the base station which downlink transmission beam (or port) it is in, so that the base station can send the other system information in the beam direction (or port) where the terminal is located. In this embodiment, assuming that the reciprocity of the terminal and the base station side is established, the port for sending the RMSI downlink uniquely corresponds to a preamble time-frequency domain resource, that is, the terminal sends the preamble on the preamble time-frequency domain resource corresponding to the RMSI, and the base station can determine the downlink beam (or port) where the current terminal is located. For example, if the terminal receives RMSI on beam2, then according to the RMSI configuration in beam 2, it is known that the corresponding preamble resource is preamble resource2, and the terminal will send the preamble on preamble resource 2. Correspondingly, if the base station receives the preamble on preamble resource2, it is determined that the UE under beam2 needs other SI, and the subsequent base station will send other SI on beam2.

[0125] In addition, other SI is pre-divided into multiple types by the system: each type of other system information corresponds to a dedicated preamble sequence, and the terminal and the base station are aware of the division method of the above other system information and the corresponding relationship between each type of other system information and the dedicated preamble sequence. At this time, if the terminal wants to request a certain type of other system information, the terminal will choose to send the preamble sequence corresponding to this type of other system information.

[0126] The base station determines which other SIs need to be transmitted on which downlink transmission ports (beams) based on the received preamble sequence. The base station can further determine the resources for sending these other SIs, including the transmission period, time window, and frequency domain position of the other SIs, and include this information in the random access response (RAR) and feed it back to the terminal. The other SIs are sent according to the resource configuration of the other SIs.

[0127] The terminal that has sent the other SI request first receives the RAR to determine the resource configuration of the other SI. Furthermore, in this embodiment, other system information is carried on the physical downlink shared channel; specifically, the other SI transmission time window contains one or more time slots of the terminal. According to the transmission period, time window, and frequency domain position of the other SI obtained in the RAR, the terminal uses SI-RNTI in the physical downlink control channel (PDCCH) in the specified frequency domain position and each slot of the transmission time window to blindly detect the downlink control information (DCI), thereby determining whether the physical downlink shared channel (PDSCH) in this slot carries the other SI requested by the terminal. The terminal will obtain other SI in a slot within the other SI transmission time window.

[0128] When there are multiple downlink transmission ports (beams) and terminals requesting other SI, the base station will transmit other SI on multiple downlink transmission ports (beams) with other SI transmission requirements, and the base station can flexibly determine which slot to use to transmit other SI of which port (beam). In addition, different terminals can request different types of other SI, so the types of other SI carried in the slots corresponding to different ports (beams) can also be different.

[0129] In this embodiment, it is assumed that reciprocity is established on both the terminal and base station sides. Similar to Embodiment 2, when reciprocity is not established on one side or both sides, more preamble resources will be configured to correspond to the downlink transmission port (beam) to complete the port (beam) polling transmission on one side or both sides. Specific implementation method 6

[0131] The specific implementation method 6 is as follows: RMSI indicates that other SI requests preamble transmission configuration; after the terminal obtains the configuration information in RMSI, it sends the preamble corresponding to the expected other SI; receives RAR, obtains the transmission resource configuration information of other SI in RAR; and blindly detects downlink control information on the transmission resource of the specified other.

[0132] This specific implementation is consistent with the process of the above-mentioned specific implementation 6, except that: the base station directly indicates the transmission resource configuration information of other SI in RAR, that is, the specific transmission resources of subsequent other SI. At this time, the terminal does not need to determine whether other SI is included by blindly checking the downlink control information in each slot within the transmission time window, but directly blindly checks DCI in the specified slot, obtains the scheduling information of other SI in PDSCH in DCI, and receives other SI according to the scheduling information.

[0133] It should be noted that the other system information (other SI) request configuration information is configured through the remaining minimized system information (RMSI) or through dedicated RRC information. Specific implementation method 7

[0135] This specific implementation mode 7 is as follows: the following three mechanisms coexist, and the terminal determines the acquisition method of other SI by receiving other system information (other SI) request configuration information.

[0136] Mode 1: The other system information (other SI) request configuration information includes the sending configuration of the request information of other system information (preamble sending configuration), as well as the transmission period, time window, and frequency domain position of other SI. After the terminal obtains the other SI request configuration information, it sends the preamble according to the preamble sending configuration, indicates the downlink transmit beam and the type of other SI to be obtained to the base station, and defaults to blindly detect the DCI of other SI in the PDCCH of each slot within the transmission time window of other SI, and receives the other SI carried in the PDSCH according to the other SI scheduling information carried in the DCI.

[0137] Mode 2: If the other system information (other SI) request configuration information does not include the transmission period, time window, and frequency domain position of other SI, and includes the sending configuration of other SI request information and the random access response RAR receiving configuration; then the terminal shall connect to RAR by default according to the RAR receiving configuration, and further obtain the scheduling information of other SI; at this time, the scheduling information of other SI contained in RAR can be the transmission period, time window, and frequency domain position of other SI; or the specific scheduling information of other SI (that is, the specific slot in which other SI is carried). If it is the former, the terminal still needs to go to the PDCCH of each slot within the transmission time window of other SI to blindly detect the DCI of other SI, and receive the other SI carried in PDSCH according to the other SI scheduling information carried in DCI; if the scheduling information of other SI in RAR is the specific scheduling information of other SI, the terminal directly goes to the slot indicated by the scheduling information to blindly detect DCI in PDCCH, and receives the other SI carried in PDSCH according to the other SI scheduling information carried in DCI.

[0138] Mode 3: If the other system information (other SI) request configuration information includes the sending configuration of other SI request information, the transmission period, time window, and frequency domain position of other SI, and also includes the random access response RAR receiving configuration; at this time, after the terminal sends the preamble according to the sending configuration of the other SI request information, there are two options: Option 1, blindly detect the DCI of other SI in the PDCCH of each slot within the transmission time window of other SI, and receive the other SI carried in the PDSCH according to the other SI scheduling information carried in the DCI; Option 2, you can try to receive RAR. If the RAR has specific scheduling information, it can avoid blind detection of multiple slots in the time window, and directly go to the slot indicated by the scheduling information to blindly detect DCI in the PDCCH, and receive the other SI carried in the PDSCH according to the other SI scheduling information carried in the DCI. If the RAR is not received, blindly detect multiple slots in the time window according to Option 1.
