Detailed ways

Specific embodiments of the present disclosure will be further described in detail below with reference to the drawings and embodiments. The following examples are intended to illustrate the disclosure, but are not intended to limit the scope of the disclosure.

Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of a system applicable to an embodiment of the present disclosure. As shown in FIG. 1, the system includes a base station 101 and a user equipment 102. The base station 101 and the user equipment 102 can communicate through a network. The base station 101 can instruct the base station 101 to transmit the current OSI by broadcasting the indication information. The user equipment 102 may perform an operation corresponding to the mode according to the manner in which the base station 101 indicated by the received indication information transmits the current OSI.

In the embodiment of the present disclosure, the base station 101 may be an evolved base station (Evolutional Node B, eNB or eNodeB for short), or a base station (gNB for short) in a 5G network. The user device 102 can be a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), or a wearable device. Equipment (Wearable Device), etc.

In the disclosed embodiment, it is considered that in the 3GPP 5G NR study, a multi-beam scanning scene is added. In the multi-beam scanning scenario, using the broadcast transmission mode to transmit the OSI not only increases system overhead, wastes resources, but also greatly increases the transmission delay of the OSI. Therefore, in the embodiment of the present disclosure, the base station 101 can directly indicate that the mode of transmitting the current OSI is the user requesting the transmission mode, that is, after receiving the OSI request information of the user equipment 102, the OSI is sent to the user equipment 102. Therefore, the transmission mode of the OSI can be standardized, the system overhead can be reduced, the waste of resources can be reduced, and the transmission delay of the OSI can be reduced. It should be noted, however, that the present disclosure does not exclude that the base station 101 simultaneously instructs it to transmit the current OSI in a broadcast transmission manner, that is, broadcasts the OSI in a preset period.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a method for transmitting another system information OSI according to an embodiment of the present disclosure. As shown in FIG. 2, the method includes:

Step 201: Broadcast first indication information, where the first indication information is used to indicate that the base station transmits the current OSI group in a manner that the user requests a transmission mode, where each of the OSI groups includes at least one OSI.

In this step, each of the OSI groups includes at least one OSI. For example, OSI group 1 may include only one OSI; OSI group 2 may include two OSIs; OSI group may include five OSIs. In this way, integrating at least one OSI into one OSI group can improve resource utilization and reduce the transmission delay of the OSI in the same OSI group.

Optionally, the current OSI group may be at least part of an OSI group in all OSI groups.

Specifically, the first indication information may be used to indicate that the manner in which the base station transmits the current all OSI group is a user requesting a transmission mode; the first indication information may also be used to indicate that the base station transmits a part of the OSI group. The user requests a transmission mode, wherein each of the OSI groups includes at least one OSI. In a specific embodiment, by setting the broadcast indicator parameter of the OSI group X to “0”, the manner in which the base station transmits the OSI group X is instructed to request the transmission mode by the user; the broadcast indicator parameter of the OSI group X is set to “ 1", indicating that the base station transmits the OSI group X in a broadcast transmission mode. The OSI group X represents any OSI group in the OSI group that the base station can transmit.

For the case where the first indication information is used to indicate that the base station transmits the current all OSI group, the user requests the transmission mode, and after receiving the OSI request information, the base station sends the requested OSI group to the user equipment that sends the request. . This standardizes the transmission method of OSI.

For the case where the first indication information is used to indicate that the base station transmits a part of the OSI group, the user requests the transmission mode. For the part of the OSI group, after receiving the OSI request information, the base station sends the request to the user equipment that sends the request. The OSI group of the request can understand that the OSI sent by the base station is an OSI group in the part of the OSI group; for other OSI groups except the part of the OSI group, the base station can transmit it by means of broadcast transmission.

Optionally, the base station may broadcast the first indication message by using an RMSI (Remaining Minimum System Information) or a PDCCH (Physical Downlink Control Channel). The RMSI is transmitted on the PDSCH (Physical Downlink Shared Channel) through PDCCH scheduling.

Optionally, after step 201, the method further includes:

In this embodiment, combined with the description in step 201, it can be understood that the target OSI group can be any OSI group specified by the base station to be transmitted by the user in the transmission mode.

In this step, in order to request the target OSI group, the user equipment may obtain the preamble corresponding to the target OSI group by searching the correspondence between the preamble and the OSI group, and carry the preamble corresponding to the target OSI group, and carry it in the OSI request information, and send it to the base station. After the base station receives the OSI request information, the base station can obtain the preamble carried therein by parsing the OSI request information, and after determining the correspondence between the preamble and the OSI group, determining that the user equipment requests the target OSI group, The target OSI group is sent to the user equipment.

The correspondence between the preamble and the OSI group may be predefined in a communication protocol between the base station and the user equipment. In this way, the base station and the user equipment can directly obtain the correspondence between the preamble and the OSI group.

In the application scenario, optionally, before step 201, the method further includes:

The available preambles are transmitted through the RMSI or PDCCH.

Specifically, the base station may determine the available preamble according to the preamble carried in the received request information and the corresponding result of the request, and broadcast the available time to the user equipment through the RMSI or the PDCCH when the preset period is reached. Leading. In this way, the user equipment can determine the available preamble and receive the requested OSI group sent by the base station after transmitting the corresponding OSI request using the preamble present in the available preamble. Therefore, the number of invalid requests of the user equipment can be reduced, and system overhead can be saved.

For example, when the user equipment 1 and the user equipment 2 determine that there is a preamble corresponding to the OSI group X among the available preambles, the user equipment 1 and the user equipment 2 can use the preamble to transmit the OSI request information of the OSI group X at the same time. In this way, after receiving the request information of the user equipment 1 and the user equipment 2, the base station can send the OSI group X requested by the user equipment 1 and the user equipment 2 to the user equipment 1 and the user equipment 2, so that the number of invalid requests of the user equipment can be reduced. , saving system overhead.

Alternatively, the user equipment 1 determines that there is a preamble corresponding to the OSI group X among the available preambles, and uses the preamble to transmit the OSI request information of the OSI group X at the first moment. It should be noted that if the request of the user equipment 1 is unsuccessful, the preamble corresponding to the OSI group X is always occupied by the user equipment 1, and the preamble corresponding to the OSI group X does not exist in the preamble available during this period; if the user equipment 1 requests If successful, the preamble corresponding to the OSI group X is released into the available preamble, and the preamble corresponding to the OSI group X exists in the available preamble.

Therefore, at the second moment, if the request of the user equipment 1 is still unsuccessful, indicating that the preamble corresponding to the OSI group X does not exist in the preamble available at this moment, the user equipment 2 may be released into the preamble in the preamble, that is, detected. If there is a preamble corresponding to the OSI group X in the available preamble, the preamble is used to send the OSI request information of the OSI group X. If the request of the user equipment 2 is successful, the preamble has been released to the preamble at this moment, and the available preamble is available. If there is a preamble corresponding to the OSI group X, then the user can use the preamble to send the OSI request information of the OSI group X. In this way, after receiving the request information of the user equipment 2, the base station can send the OSI group X requested by the user equipment 2 to the user equipment 2, thereby reducing the number of invalid requests of the user equipment and saving system overhead.

In practical applications, the preamble corresponding to the OSI group X can be set to "yes", indicating that the preamble corresponding to the OSI group X is available; the preamble corresponding to the OSI group X is set to "no", indicating that the OSI group X corresponds to The leader is not available.

In addition, the correspondence between the preamble and the OSI group can also be pre-configured by the base station. In this way, the base station can change the correspondence between the preamble and the OSI group by using the broadcast message at different time points, and the flexibility of the configuration of the correspondence between the preamble and the OSI group can be improved.

In this way, the user equipment can obtain the correspondence between the preamble and the OSI group, and carry the preamble corresponding to the target OSI group in the OSI request information according to the correspondence between the preamble and the OSI group.

Further, when the base station transmits the correspondence between the preamble and the OSI group through the RMSI or the PDCCH, the base station may also transmit the available preamble through the RMSI or the PDCCH.

Optionally, the OSI request information is carried in the message 1 in the random access procedure. The message 1 (Msg.1) is a message for sending a random access preamble in a random access procedure.

Pre-set to request the preamble of the OSI; or,

a preamble sequence in the random access procedure; or,

User uplink pilot sequence.

In the embodiment of the present disclosure, the preamble corresponding to the target OSI group carried in the OSI request information may be a preset preamble for requesting the OSI, and the preamble corresponding to the target OSI group is dedicated for the request. The preamble of the OSI is designed to be the preamble of the OSI design. The preamble corresponding to the target OSI group carried in the OSI request information may also be a preamble shared with the random access procedure; The preamble corresponding to the carried target OSI group may also be a user uplink pilot sequence. In addition, the preamble corresponding to the target OSI group carried in the OSI request information may also be any resource that can identify the carrying information, and may be determined according to actual needs, which is not limited herein.

Please refer to FIG. 3. FIG. 3 is a schematic diagram of a correspondence between a preamble and an OSI group according to an embodiment of the present disclosure. As shown in FIG. 3, the preamble 1 is bound to the OSI group 1, and represents a one-to-one correspondence. Among them, the OSI group 1 includes two OSIs, OSI1 and OSI2.

Please refer to FIG. 4. FIG. 4 is a schematic diagram of another relationship between a preamble and an OSI group according to an embodiment of the present disclosure. As shown in FIG. 4, the preamble 2 and the preamble 3 are bound to the OSI group 2, indicating a many-to-one correspondence. That is, an OSI group is bound to at least two preambles. The OSI group 2 includes an OSI of OSI3, and the preamble 2 and the preamble 3 can be integrated into one preamble group.

In the schematic diagram of the correspondence between the preamble and the OSI group provided by the embodiment of the present disclosure, the solid line with an arrow pointing from the preamble to the OSI group indicates that the preamble is bound to the OSI group.

Therefore, it can be understood that, in practical applications, in the correspondence between the preamble and the OSI group, any OSI group in the partial OSI group may be bound to only one preamble, and any OSI group in other OSI groups may be bound. At least two predecessors. For example, the correspondence between the preamble and the OSI group includes six preambles, namely, preamble 1, preamble 2, preamble 3, preamble 4, preamble 5, and preamble 6; and three OSI groups, which are OSI group 1, OSI group 2, and OSI, respectively. Group 3. In the corresponding relationship, OSI group 1 can only bind one preamble, which is preamble 1; OSI group 2 can bind two preambles, which are preamble 2 and preamble 4; OSI group 2 can bind two preambles, which is preamble 3 , Lead 3 Lead 5 and Lead 6.

Of course, in the correspondence between the preamble and the OSI group, any OSI group in the entire OSI group may be bound to only one preamble; or any OSI group in all OSI groups may be bound to at least two preambles.

In this embodiment, the relationship between the preamble and the OSI group is a one-to-one correspondence, and the different user equipments can use different preambles to request the same OSI group, thereby effectively alleviating the user equipment. Ask for a collision.

After receiving the OSI request information sent by the user equipment for requesting the target OSI group, the base station may respond to the received OSI request information by using the following two methods.

Manner 1: Optional, after the step of receiving the OSI request information sent by the user equipment for requesting the target OSI group, the method further includes:

Sending the target OSI group to the user equipment.

In this embodiment, after receiving the OSI request information for requesting the target OSI group sent by the user equipment, the base station sends the second indication information, the second indication, to the user equipment, corresponding to the first indication information. The information is used to indicate that the base station transmits the current target OSI group in a broadcast transmission manner, and sends the target OSI group to the user equipment. Therefore, after receiving the second indication information, and determining that the manner in which the base station transmits the current target OSI group is a broadcast transmission mode, the user equipment may receive the target OSI group sent by the base station in a corresponding window.

In a specific embodiment, the manner in which the base station transmits the target OSI group is a broadcast transmission mode by setting the broadcast indicator parameter of the target OSI group to “1”.

In this embodiment, the message 2 (Msg. 2), the message 3 (Msg. 3), and the message 4 (Msg. 4) in the initial access process may be omitted, thereby distinguishing the related technologies and effectively reducing the transmission time of the OSI. Delay.

For a better understanding of the present embodiment, please refer to FIG. 5. FIG. 5 is a schematic flowchart of a method for transmitting an OSI according to another embodiment of the present disclosure. As shown in FIG. 5, the method includes:

Step 501: The base station broadcasts available preambles.

Step 502: The user equipment receives an available preamble.

Step 503: The base station broadcasts the first indication information, where the first indication information is used to indicate that the base station transmits the current OSI group in a manner that the user requests the transmission mode, where each of the OSI groups includes at least one OSI.

Step 504: The user equipment receives the first indication information.

Step 505: The user equipment sends the OSI request information for requesting the target OSI group, where the OSI request information carries the preamble corresponding to the target OSI group.

Step 506: The base station receives the OSI request information.

Step 507: The base station sends the second indication information to the user equipment, where the second indication information is used to indicate that the manner in which the base station transmits the target OSI group is a broadcast transmission mode.

Step 508: The user equipment receives the second indication information.

Step 509: The base station sends the target OSI group to the user equipment.

Step 510: The user equipment receives the target OSI group.

In this embodiment, the working principle of each step may be referred to the description of the foregoing method embodiment. To avoid repetition, details are not described herein again.

In this embodiment, for the correspondence between the preamble and the OSI group, the specific correspondence between the preamble and the OSI group is different. When different user equipments request the same OSI group, the time-frequency resources and the OSI message are used in different manners. The preamble corresponding to the OSI group is carried. The following describes the different modes of user equipment A and user equipment B as follows:

For example, if the preamble and the OSI group have a one-to-one correspondence in the correspondence between the preamble and the OSI group, the receiving user equipment sends the OSI request information for requesting the target OSI group. Steps include:

In this implementation, since the target OSI group is bound to only one preamble, the former 1 is taken as an example for explanation:

User equipment A and user equipment B may send a preamble 1 bound to a target OSI group on the same time-frequency resource. Correspondingly, the base station can receive the OSI request information sent by the user equipment A and the user equipment B for requesting the same target OSI group on the same time-frequency resource, and the OSI request information sent by the user equipment A and the user equipment B carries the preamble 1.

Referring to FIG. 7, FIG. 7 is a schematic diagram of another different user equipment requesting a target OSI group according to an embodiment of the present disclosure. User equipment A and user equipment B may also be configured to be bound to a target OSI group on different time-frequency resources. Leading 1. Correspondingly, the base station may receive the OSI request information sent by the user equipment A and the user equipment B for requesting the same target OSI group on different time-frequency resources, and the OSI request information sent by the user equipment A and the user equipment B carries the preamble 1.

It should be noted that, when the user equipment A and the user equipment B transmit the preamble 1 on different time-frequency resources, it can be known from the above embodiment that if the user equipment A sends the preamble 1 in advance, the user equipment B is in the user equipment A. Leading 1 can only be sent after the target OSI group is successfully requested.

It should be noted that, in the embodiment of the present disclosure, the time-frequency resource may be represented by a coordinate system in which the abscissa is the time t and the ordinate is the frequency f. As shown in the schematic diagram of the different user equipments requesting the target OSI group provided by the present disclosure, But it is not limited to this. In the schematic diagram of the different user equipments of the present disclosure requesting the target OSI group, the solid line with the arrow pointed to by the user equipment indicates that the preamble is carried in the OSI request information sent by the user equipment; in addition, different positions in the coordinate system Indicates different time-frequency resources.

Secondly, if the preamble and the OSI group have a many-to-one correspondence in the correspondence between the preamble and the OSI group, the receiving user equipment sends the OSI request information for requesting the target OSI group. Steps include:

The OSI request information sent by the at least two user terminals for requesting the same target OSI group is received on the different time-frequency resources, and the OSI request information sent by the at least two user terminals carries the same preamble; or

In this implementation, since the target OSI group is bound with at least two preambles, the former 2 and the preamble 3 are taken as an example for description:

Referring to FIG. 8, user equipment A and user equipment B may send the same preamble among multiple preambles bound to the target OSI group on the same time-frequency resource. The preamble identifier in FIG. 8 is preamble 2. Correspondingly, the base station may receive, on the same time-frequency resource, the user equipment A and the user equipment B to request the same target OSI group, and the OSI request information sent by the user equipment A and the user equipment B carries the preamble 2.

Referring to FIG. 9, the user equipment A and the user equipment B may also send the same preamble among the plurality of preambles bound to the target OSI group on the same or different time-frequency resources. The preamble identifier in FIG. 9 is the preamble 3. Correspondingly, the base station may receive the OSI request information sent by the user equipment A and the user equipment B for requesting the same target OSI group on different time-frequency resources, and the OSI request information sent by the user equipment A and the user equipment B carries the preamble 3.

Referring to FIG. 10, user equipment A and user equipment B may also transmit preamble 2 and preamble 3 bound to the target OSI group on the same time-frequency resource. Correspondingly, the base station can receive the OSI request information sent by the user equipment A and the user equipment B for requesting the same OSI group on the same time-frequency resource, where the OSI request information sent by the user equipment A carries the preamble 2, the user The preamble 3 is carried in the OSI request message sent by device A. The solid line with an arrow pointing to the solid line frame by the dotted line frame in FIG. 10 indicates that the preamble in the dotted line frame can be transmitted through the time-frequency resource where the solid line frame is located.

Referring to FIG. 11, user equipment A and user equipment B may also transmit preamble 2 and preamble 3 bound to the target OSI group on different time-frequency resources. Thereby, the probability of the user equipment requesting a collision can be effectively reduced. Correspondingly, the base station may receive the OSI request information sent by the user equipment A and the user equipment B for requesting the same target OSI group on different time-frequency resources, where the OSI request information sent by the user equipment A carries the preamble 2, the user The preamble 3 is carried in the OSI request message sent by device A.

It should be noted that when the user equipment A and the user equipment B transmit the preamble 3 on different time-frequency resources, it can be seen from the above embodiment that if the user equipment A sends the preamble 3 in advance, the user equipment B is in the user equipment A. The preamble 3 can only be sent after the target OSI group is successfully requested.

Manner 2: After the step of receiving the OSI request information sent by the user equipment for requesting the target OSI group, the method further includes:

Sending an OSI request success confirmation message to the user equipment;

Sending the target OSI group to the user equipment.

In this embodiment, the difference from the first method is that the base station further sends the OSI request success confirmation information to the user equipment after receiving the OSI request information sent by the user equipment for requesting the target OSI group, so that the The user equipment repeatedly transmits OSI request information for requesting the target OSI group.

In this embodiment, the message 3 (Msg. 3) and the message 4 (Msg. 4) in the initial access process may be omitted, so that the transmission delay of the OSI can be effectively reduced.

It should be noted that the implementations of other the same steps can be referred to the related description in the first mode. To avoid repetition of the description, details are not described herein again.

For a better understanding of the present embodiment, please refer to FIG. 12, which is a schematic flowchart of a method for transmitting an OSI according to another embodiment of the present disclosure. As shown in FIG. 12, the method includes:

Step 1201: The base station broadcasts available preambles.

Step 1202: The user equipment receives an available preamble.

Step 1203: The base station broadcasts the first indication information, where the first indication information is used to indicate that the base station transmits the current OSI group in a manner that the user requests the transmission mode, where each of the OSI groups includes at least one OSI.

Step 1204: The user equipment receives the first indication information.

Step 1205: The user equipment sends the OSI request information for requesting the target OSI group, where the OSI request information carries the preamble corresponding to the target OSI group.

Step 1206: The base station receives the OSI request information.

Step 1207: The base station sends an OSI request success confirmation message to the user equipment.

Step 1208: The user equipment receives the OSI request success confirmation information.

Step 1209: The base station sends the second indication information to the user equipment, where the second indication information is used to indicate that the manner in which the base station transmits the target OSI group is a broadcast transmission mode.

Step 1210: The user equipment receives the second indication information.

Step 1211: The base station sends the target OSI group to the user equipment.

Step 1212: The user equipment receives the target OSI group.

The message 2 (Msg. 2) is a message for sending a random access response during the random access procedure.

In this implementation manner, since the base station further sends the OSI request success confirmation information to the user equipment, in order to avoid a collision problem when the base station sends the OSI request success confirmation information to different devices, the method is different from the first OSI group. When only one preamble is bound, user equipment A and user equipment B need to send preambles bound to the target OSI group on different time-frequency resources. It should be noted that, as shown in the foregoing embodiment, if the user equipment A sends the preamble in advance, the user equipment B can send the preamble after the user equipment A successfully requests the target OSI group.

Similar to the first method, since the base station also sends the OSI request success confirmation information to the user equipment, the user equipment A and the user equipment are different from the first method in order to prevent the base station from transmitting a collision request to the different device. B may not transmit the same preamble among the plurality of preambles bound to the target OSI group on the same time-frequency resource. For the implementation of the other steps, refer to the related description in the first method. To avoid repetition, the details are not described herein.

Optionally, the base station may send the second indication information to the user equipment by using an RMSI or scheduling a PDCCH of the target OSI group.

Optionally, the base station may send the target OSI group to the user equipment by using a physical downlink shared channel (PDSCH).

In the above embodiment, the base station may indicate that the base station transmits the current OSI group by using the first indication message to request the transmission mode of the user, thereby standardizing the transmission mode of the OSI.

Referring to FIG. 13, FIG. 13 is a schematic flowchart of another system information OSI according to another embodiment of the present disclosure. As shown in FIG. 13, the method includes:

Step 1301: Receive first indication information, where the first indication information is used to indicate that a manner in which the base station transmits the current OSI group is a user requesting a transmission mode, where each of the OSI groups includes at least one OSI.
