Description

Resource allocation method and equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource allocation method and device.

Background

In a New Radio (NR) system, system messages are divided into a main system information block (MIB), Remaining Minimum System Information (RMSI), and Other System Information (OSI). Here, the RMSI is a system information block 1 (SIB 1). Herein, other SIBs except the MIB and the SIB1, such as SIB2 or SIB3, may be referred to as OSI, and OSI with the same period may also be encapsulated into one System Information (SI) for transmission.

In the NR system, the SI may be transmitted by a periodic broadcast manner, or may be transmitted according to a request of the terminal device. If the SI is sent according to the request of the terminal device, the terminal device may generally send the request to the base station in a random access procedure. Currently, a base station may first configure a Physical Random Access Channel (PRACH) resource dedicated to a terminal device to send a request, so that the terminal device may request an SI from the base station through the PRACH resource configured by the base station. For example, referring to fig. 1, in fig. 1, resource 1 corresponds to SI #1, which means that the base station requests the terminal device to configure the SI #1 with resource 1, and so on. In this current approach, the base station needs to list resources separately for each SI in the configuration information for configuring PRACH resources, for example, in fig. 1, 5 SIs are sent by the system according to the request of the terminal device, and then the base station needs to list 5 entries for these 5 SIs in the configuration information, even if two or more SIs share one resource, for example, in fig. 1, the resources configured by the base station for requesting SI #4 and SI #5 for the terminal device are both resource 4, but also need to list two entries for SI #4 and SI # 5. This obviously increases the number of bits of configuration information, which is a waste of resources.

Disclosure of Invention

The embodiment of the application provides a resource configuration method and equipment, which are used for reducing the bit number of configuration information.

In a first aspect, a first resource allocation method is provided, where the method includes: generating configuration information, wherein the configuration information is used for indicating a resource configured for requesting system information for a terminal device, and the configuration information includes first record information and second record information, the first record information is used for indicating a resource configured for requesting system information for the terminal device, the second record information is used for indicating a resource configured for requesting remaining system information for the terminal device, and the remaining system information is other system information except the system information corresponding to the first record information; and sending the configuration information.

The method may be performed by a first communication device, for example a network device or a communication device capable of supporting a network device to implement the functions required by the method, or for example a chip capable of being provided in a network device, for example a base station.

In this embodiment, the configuration information includes first record information that may be used to indicate a resource used by the terminal device to request one system information, and the configuration information further includes second record information that may indicate a resource used by the terminal device to request the remaining system information, that is, the first record information may be listed separately for a part of the SI in the configuration information, or a piece of second record information may be set for a part of the SI, and the remaining SI may be requested through the resource indicated by the second record information. By the method, information does not need to be listed and recorded for all SI independently, the bit number of configuration information is effectively reduced, and resource saving is facilitated.

With reference to the first aspect, in a possible implementation manner of the first aspect, the number of the first record information is one or more, and when the number of the first record information is multiple, resources indicated by two pieces of first record information in the multiple pieces of first record information are used to request two different pieces of system information.

Since one piece of first record information may be used to indicate a resource configured for requesting one piece of system information for the terminal device, for example, the system information with a certain independence may be requested through the first record information, where the independence means that when such system information is requested, other system information is not generally requested, and then the specific number of the first record information may be determined according to the number of the system information with a certain independence. Of course, the system information requested by the first record information is not limited thereto. In summary, the embodiment of the present application does not limit the number of the first record information. In addition, since the first record information is listed individually, if the number of the first record information is plural, the resources indicated by two pieces of the first record information included in the plural pieces of the first record information can be used to request different system information, which can make the best use of the first record information as much as possible.

With reference to the first aspect, in a possible implementation manner of the first aspect, the number of the first record information is one, and the resource indicated by the first record information is different from the resource indicated by the second record information, or the resource indicated by the first record information is the same as the resource indicated by the second record information.

In the case that the number of the first record information is one, the resource indicated by the first record information and the resource indicated by the second record information may be different resources, so that different system information may be requested through different resources, which is helpful to improve efficiency of requesting system information. Alternatively, the resource indicated by the first record information and the resource indicated by the second record information may be the same resource, so as to improve the utilization rate of the resource.

With reference to the first aspect, in a possible implementation manner of the first aspect, the number of the first record information is multiple, a resource indicated by each of the multiple pieces of first record information is different from a resource indicated by the second record information, or a resource indicated by one of the multiple pieces of first record information is the same as a resource indicated by the second record information.

In the case that the number of the first record information is multiple, the resource indicated by the multiple pieces of the first record information and the resource indicated by the second record information may both be different resources, so that different system information may be requested through different resources, which is helpful for improving the efficiency of requesting the system information. Alternatively, the resource indicated by one of the first record information and the resource indicated by the second record information may be the same resource, so as to improve the utilization rate of the resource. For example, the first record information indicating that the indicated resource is the same resource as the resource indicated by the second record information may be the last first record information in the plurality of pieces of first record information, or the first record information indicating that the indicated resource is the same resource as the resource indicated by the second record information may also be other first record information in the plurality of pieces of first record information, which is not limited specifically.

With reference to the first aspect, in a possible implementation manner of the first aspect, the configuration information further includes third record information, where the third record information is used to indicate resources configured to request all system information for a terminal device.

The third record information may be used to indicate resources configured for the terminal device to request all the system information, and then, if the terminal device needs to request all the system information, the resource request indicated by the third record information may be directly requested. It can be seen that, the configuration information provided by the embodiment of the application provides corresponding record information for various request requirements of the terminal device, and is flexible.

With reference to the first aspect, in a possible implementation manner of the first aspect, the configuration information is further used to indicate that the terminal device is supported to send a second message for requesting system information through the Msg3 in the random access process.

If the network device configures the terminal device with the resource for requesting the system information according to the prior art, the terminal device needs to request the system information through the resource configured by the network device by default, and the resource configured by the network device is the resource of the Msg 1. In the embodiment of the application, it is considered that resources of the Msg1 are limited, and only limited information amount can be sent by the terminal device, and if the terminal device needs to send more information, the resource through the Msg1 may be difficult to implement, so the configuration information may also indicate that the terminal device is supported to send the second message through the Msg3, and the Msg3 is relatively rich in resources, so the terminal device can send more information through the Msg 3.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: and sending a first message, wherein the first message is used for indicating the sending mode of the system information.

If the terminal device does not know how the network device sends the system information, the terminal device does not know how to detect the system information, and the terminal device may increase the number of blind tests or may miss the system information. Therefore, in the embodiment of the present application, the sending mode of the system information may also be indicated by the first message, so that the terminal device may determine how the network device sends the system information, reduce the number of blind tests as much as possible, save power consumption, avoid missing detection of the system information as much as possible, and improve the detection success rate of the system information.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: receiving a second message from the terminal device, wherein the second message is used for requesting system information, and the second message is also used for indicating a sending mode of the system information.

The terminal device can also indicate which sending mode the terminal device needs to adopt for the system information through the second message, so that the network device can send the system information according to the indication of the terminal device, and the requirements of the terminal device are better met.

With reference to the first aspect, in a possible implementation manner of the first aspect, the sending manner of the system information includes: transmitting the system information in a current modification period or transmitting the system information in a next modification period; and/or, the system information is sent in a unicast mode or in a broadcast mode.

At present, the network device may send the system information in the current modification period or in the next modification period, and the terminal device may perform blind detection in both the current modification period and the next modification period without knowing, thereby increasing the number of blind detections. In the embodiment of the application, the system information can be determined in which modification period the network device sends the system information through the sending mode of the system information, so that the blind test times of the terminal device are reduced. In addition, it is possible to determine whether the system information is transmitted in a unicast manner or in a broadcast manner, thereby making it possible to clarify a system information reception manner.

With reference to the first aspect, in a possible implementation manner of the first aspect, the receiving a second message from a terminal device includes: receiving the second message from the terminal device through a resource for requesting the system information indicated by the configuration information in Msg1 in a random access process; or, receiving the second message from the terminal device through Msg3 in a random access process.

The terminal device may send the second message via the Msg1 resource configured by the configuration information, or if the configuration information indicates that the terminal device is supported for sending the second message via Msg3, the terminal device may also send the second message via the Msg3 resource. For example, the terminal device needs to indicate the sending method of the system information in the second message, which can be understood that the terminal device needs to carry information for requesting the system information and information for indicating the sending method of the system information in the second message, and the information amount of the second message may be large, and the terminal device can send the second message through the Msg3 resource, so as to improve the sending success rate of the second message. Alternatively, the second message may be transmitted via the Msg1 resource and the Msg3 resource, and in this case, the information requesting the system information and the information indicating the system information transmission method may be decoupled, the information requesting the system information may be transmitted via the Msg1 resource, and the information indicating the system information transmission method may be transmitted via the Msg3 resource. Specifically, how the terminal device sends the second message is not limited in the embodiment of the present application.

In a second aspect, a first method for transmitting system information is provided, the method comprising: sending a first message, wherein the first message is used for indicating a sending mode of system information, and the sending mode of the system information comprises the following steps: transmitting the system information in a current modification period or transmitting the system information in a next modification period; and/or, the system information is sent in a unicast mode or in a broadcast mode.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets, smart helmets, smart jewelry and the like for monitoring physical signs.

2) A network device, e.g., including a base station (e.g., access point), may refer to a device in an access network that communicates over the air, through one or more cells, with wireless terminal devices. The network device may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network.

3) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. The "plurality" means two or more, and in view of this, the "plurality" may also be understood as "at least two" in the embodiments of the present application. By "at least two", two or more strips are to be understood, for example two, three or more strips. "at least one" is to be understood as meaning one or more, for example one, two or more, strips. Similarly, the understanding of the description of "a plurality" and the like is similar. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" generally indicates that the preceding and following related objects are in an "or" relationship, unless otherwise specified.

Unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing between a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects.

First, technical features related to embodiments of the present application are described.

In the NR system, system messages are divided into MIB, RMSI, and OSI. Wherein, RMSI is SIB 1. Other SIBs than MIB and SIB1, such as SIB2 or SIB3, may be referred to as OSI, and OSI with the same period may be encapsulated into one SI transmission. Wherein, which OSI each SI includes is determined by the base station without limitation.

In the NR system, the SI may be transmitted by a periodic broadcast manner, or may be transmitted according to a request of the terminal device. Whether a certain SI is transmitted by periodic broadcast or upon request of the terminal device is indicated in the SIB 1. The SIB1 contains the parameters: SI-broadcast enumeration (SI-broadcast status issued) { broadcast (broadcast), non-broadcast (non-broadcast) }, which is used to indicate the sending status of a certain SI, for example, for a SI, the value of the parameter is broadcast, which means that the SI is sent in a periodic broadcast manner, or for the SI, the value of the parameter is non-broadcast, which means that the SI is sent based on the request of the terminal device. The request transmission based on the terminal device may be referred to as on-demand (on-demand) transmission or may also be referred to as non-broadcast transmission.

For SI sent on demand, the base station also configures how the terminal device sends the request:

the terminal device sends a request message for requesting SI to the base station through a first message (Msg1) in a random access process, and the base station sends a confirmation message to the terminal device through a second message (Msg2) in the random access process. Among them, Msg1 is random access preamble (preamble), and Msg2 is Random Access Response (RAR)).

Alternatively, the terminal device sends a request message for requesting SI to the base station through a third message (Msg3) in the random access procedure, and the base station sends a confirmation message to the terminal device through a fourth message (Msg4) in the random access procedure. Here, Msg4 is a contention resolution message.

It is noted that the acknowledgement message sent by the base station to the terminal device is not SI, but only an acknowledgement message to the request message sent by the terminal device.

The terminal device may send the request message to the base station in different ways, and the choice of which way can be determined by the base station. For example, the base station may first configure PRACH resources dedicated to the terminal device sending the request, so that the terminal device may request SI from the base station through the PRACH resources configured by the base station. If the base station configures PRACH resources for the terminal device, that is, the terminal device needs to send the request message through Msg1, that is, the PRACH resources configured by the base station are resources in Msg1, then if the base station does not configure PRACH resources for the terminal device, the terminal device may determine to send the request message through Msg 3. Currently, if the base station configures PRACH resources for the terminal device, the base station may notify the terminal device through SIB1, and if the terminal device does not acquire information of PRACH resources configured by the base station in received SIB1, it may be determined that the request message is to be sent through Msg 3. And the main discussion herein is the case where the base station configures PRACH resources for the terminal device.

The base station may configure PRACH resources for the terminal device to transmit a request message for requesting the SI through the configuration information. For example, fig. 1 may be referenced for one type of configuration information determined by a base station. In fig. 1, resource 1 corresponds to SI #1, which means that the resource allocated by the base station to request SI #1 for the terminal equipment is resource 1, and so on. In this current approach, the base station needs to list resources separately for each SI in the configuration information for configuring PRACH resources, for example, in fig. 1, 5 SIs are sent by the system according to the request of the terminal device, and then the base station needs to list 5 entries for these 5 SIs in the configuration information, even if two or more SIs share one resource, for example, in fig. 1, the resources configured by the base station for requesting SI #4 and SI #5 for the terminal device are both resource 4, but also need to list two entries for SI #4 and SI # 5. This obviously increases the number of bits of configuration information, which is a waste of resources.

Alternatively, another configuration information determined by the base station may refer to fig. 2. In fig. 2, resource a corresponds to all SIs, that is, in this manner, the configuration information lists information of only one resource for requesting all SIs. However, if only one resource is defined to request all the SI, the granularity of the request will be coarser. For example, a terminal device may only need to request SI #1, but if the terminal device sends a request message over resource a as described above, the base station will send all SIs to the terminal device, i.e. a request sent over a common resource, the requested in fact being all SIs. This also results in unnecessary waste of transmission resources.

In view of this, an embodiment of the present application provides a resource allocation method, and in the embodiment of the present application, in the allocation information, a piece of record information may be set separately for a part of the SI, and a resource indicated by a piece of record information may request a remaining SI. In this way, information does not need to be separately listed and recorded for all the SIs, and the bit number of the configuration information is effectively reduced. And because there is already a part of the SI requested separately, the granularity requested by the resource for requesting the remaining SI is not too large, which also helps to reduce the waste of transmission resources.

The embodiment of the application can be applied to an evolved universal mobile telecommunications system terrestrial radio access network (E-UTRAN) system, or a Next Generation (NG) -RAN system, or can also be applied to a next generation communication system or a similar communication system.

The technical scheme provided by the embodiment of the application is described in the following with the accompanying drawings of the specification.

An embodiment of the present application provides a method for resource allocation and system information transmission, please refer to fig. 5, which is a flowchart of the method. The method can be applied to the scenario shown in fig. 3 or fig. 4, and in the following description, the application of the method provided in the embodiment of the present application to the scenario shown in fig. 3 or fig. 4 is taken as an example. In addition, the method may be performed by two communication apparatuses, for example, a first communication apparatus and a second communication apparatus, where the first communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the first communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses such as a system on chip. The same applies to the second communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, other communication apparatuses such as a system on a chip may also be used. The implementation manners of the first communication device and the second communication device are not limited, for example, the first communication device may be a network device, the second communication device is a terminal device, or both the first communication device and the second communication device are network devices, or both the first communication device and the second communication device are terminal devices, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the first communication apparatus is a network device and the second communication apparatus is a terminal device as an example. If the method provided by the embodiment of the present application is applied to the application scenario shown in fig. 3, the network device described below may be the first network device, the second network device, or the third network device in fig. 3, and if the method provided by the embodiment of the present application is applied to the application scenario shown in fig. 4, the network device described below may be the fourth network device, the fifth network device, the sixth network device, or the seventh network device in fig. 4.

S51, the network device generates configuration information, where the configuration information is used to indicate a resource configured for requesting system information for the terminal device, where the configuration information includes first record information and second record information, the first record information is used to indicate a resource configured for requesting system information for the terminal device, the second record information is used to indicate a resource configured for requesting remaining system information for the terminal device, and the remaining system information is other system information except the system information corresponding to the first record information.

The number of the first record information may be one or multiple, and the embodiment of the present application does not limit the number of the first record information. If the number of the first record information is a plurality of pieces, each piece of the first record information in the plurality of pieces of the first record information may be used to request an SI, where the plurality of pieces of the first record information includes two pieces of the first record information, and the requested SI of the two pieces of the first record information may be different SIs. For example, the SI requested by different first record information in the plurality of pieces of first record information may be different SI, or the SI requested by a part of the first record information in the plurality of pieces of first record information may be the same SI, but the SI requested by two pieces of first record information in the plurality of pieces of first record information should be different SIs, in this case, the resource indicated by the two pieces of first record information is not limited, that is, if the SI requested by two pieces of first record information is different SIs, the resource indicated by the two pieces of first record information may be different resources, or may be the same resource. For example, there are 3 pieces of first record information, namely, a first record information a for requesting SI #1, a first record information B for requesting SI #2, and a first record information C for requesting SI #3, and then SI #1, SI #2, and SI #3 may be different, or SI #1 and SI #2 may be the same SI, and SI #3 is different from SI #1 and SI #2, and it can be seen that, of these 3 pieces of first record information, there are always two pieces of first record information whose requested SI is different SI. The SI requested by the recording information is the SI requested by the resource indicated by the recording information.

The network device may configure the PRACH resource for the terminal device through the configuration information. In the embodiment of the present application, a piece of record information in the configuration information may also be referred to as an item or an entry, and the specific name is not limited. In addition, "generating" configuration information may also be understood as "determining" configuration information or "obtaining" configuration information, and the manner in which the network device obtains configuration information is not limited. One piece of record information may indicate one resource, or referred to as one piece of resource, for example, one piece of first record information may indicate a resource configured for a terminal device to request one SI, that is, if the number of the first record information is multiple, the multiple pieces of first record information may be regarded as resources listed for multiple SIs respectively. And the configuration information may include second record information in addition to the first record information, where the second record information also indicates a resource, but the resource is a common resource that the network device requests the terminal device to configure for the remaining SIs, and the terminal device requests, regardless of which SI of the remaining SIs is requested, through the resource indicated by the second record information.

As can be seen, in the configuration information, the embodiment of the present application may list the record information (the first record information) for a part of the SI, and may also set a piece of record information (the second record information) for a part of the SI, so that the remaining SI may be requested through the resource indicated by the piece of record information. By the method, information does not need to be listed and recorded for all SI independently, the bit number of configuration information is effectively reduced, and resource saving is facilitated. In addition, in this embodiment, there is the first record information listed separately, and the remaining SI is requested by the resource indicated by the second record information, then, if the terminal device requests the SI by the resource indicated by the second record information, the network device may send all the SIs corresponding to the resource indicated by the second record information to the terminal device, that is, return all the remaining SIs to the terminal device, and then the SI returned by the network device in this embodiment is relatively less compared to the case where all the SIs are requested by one common resource in the prior art, which is beneficial to saving resources.

For example, the system provides 10 SIs, SI #1 to SI #10, the network device lists the resources for SI #1 to SI #5 individually, and uses SI #6 to SI #10 as the remaining SIs to share the same resource, so the configuration information generated by the network device can refer to fig. 6. As can be seen in fig. 6, the configuration information includes 5 pieces of first record information, which is resources 1 to 5 corresponding to the resources respectively allocated by the network device for requesting SI # to SI #5 for the terminal device, and also includes second record information, which is resources 6 corresponding to the resources allocated by the network device for requesting SI #6 to SI10 for the terminal device, and thus, resource 6 can be regarded as a common resource.

In the embodiment of the present application, the number of the first record information and which SI each piece of the first record information corresponds to are not limited, and accordingly, the remaining SI corresponding to the second record information includes which SI is not limited. For example, SI having a certain independence may be configured as SI requested by the first recording information. The independence of one SI means that when a terminal device requests the SI, it may only need to request the SI, and does not need to request other SIs any more. For another type of SI, when the terminal device requests one SI, it is likely to need to request other SIs together, and this type of SI may be considered as a SI with poor independence, and for the SI with poor independence, it may be configured to request through the resource indicated by the second record information, so that the number of requests of the terminal device may be saved, one or more SI required may be requested at one time, and even if the network device returns multiple SIs, which may also be required by the terminal device, or at least a part of the multiple SIs are required by the terminal device, invalid transmission of the network device is minimized, and utilization rate of the resource is improved.

In this embodiment of the application, the resource indicated by the second record information and the resource indicated by the first record information may be different resources, specifically, if the number of the first record information is one, the resource indicated by the second record information is different from the resource indicated by the first record information, and if the number of the first record information is multiple, the resource indicated by the second record information is different from the resource indicated by each of the multiple pieces of the first record information. Referring to fig. 6, the number of the first record information is plural, for example, the resource 6 is different from each of the resources 1 to 5. In this way, the common resource may be a separate resource, and may also avoid confusion with the resource that requests the SI separately. Or, the resource indicated by the second record information and the resource indicated by the first record information may be the same resource, specifically, if the number of the first record information is one, the resource indicated by the second record information and the resource indicated by the first record information are the same resource, and if the number of the first record information is multiple, the resource indicated by the second record information and the resource indicated by one of the multiple pieces of the first record information are the same resource. This is equivalent to multiplexing resources, which contributes to resource saving. For example, the number of the first record information is multiple, the resource indicated by the second record information is the same resource as the resource indicated by one of the first record information in the multiple pieces of first record information, and the embodiment of the present application is not limited to which of the multiple pieces of first record information the one piece of first record information is. For example, the first record information may be a first record information of the plurality of pieces of first record information, or may be a last record information of the plurality of pieces of first record information, or may be other first record information of the plurality of pieces of first record information. Here, "first" and "last" may be described in order of the sequence numbers of the SI from small to large. Note that "first record information" and "first piece of first record information" represent different meanings, and "first record information" may refer to one of the plurality of pieces of first record information without limitation to which one, and "first piece of first record information" is also one of the plurality of pieces of first record information, but is related to the sorting. Taking fig. 6 as an example, the resource 6 is the same resource as one of the resources 1 to 5, and as to which resource the resource 6 is the same resource, the embodiment of the present application is not limited. Taking the resource 6 and the resource 5 as the same resource as each other, the configuration information generated by the network device may refer to fig. 7, that is, in fig. 7, the resource indicated by the second record information is the same resource as the resource indicated by the last record information of the plurality of pieces of first record information.

In addition, in the embodiment of the present application, the configuration information may further include third record information in addition to the first record information and the second record information, where the third record information does not belong to the first record information and is different from the second record information, and the third record information may indicate resources configured for requesting all SIs for the terminal device. The resource indicated by the third record information may also be understood as a common resource, except that the SI requested by the resource indicated by the third record information includes the SI corresponding to the first record information and the SI corresponding to the second record information. For example, the terminal device needs to request the SI corresponding to the first record information and needs to request the SI corresponding to the second record information, the terminal device may use the third record information to request, so as to obtain multiple SIs that need to be requested at one time. It can be seen that the third record information is included, so that the request of the terminal device can be more flexible. In the embodiment of the present application, the SI corresponding to the record information refers to the SI that the resource indicated by the record information is used for requesting.

For example, the system provides 10 SIs, SI #1 to SI #10, the network device lists the resources for SI #1 to SI #5 individually, and SI #6 to SI #10 share the same resource as the remaining SIs, so the configuration information generated by the network device can refer to fig. 8. As can be seen in fig. 8, the configuration information includes 5 pieces of first record information, which corresponds to the resources respectively allocated by the network device for the terminal device to request SI # to SI #5, and is resources 1 to 5, the configuration information includes second record information, which corresponds to the resources allocated by the network device for the terminal device to request SI #6 to SI #10, and is resources 6, and the configuration information further includes third record information, which corresponds to the resources allocated by the network device for the terminal device to request SI #1 to SI #10, and is resources 7. Where resources 6 and 7 can both be considered as common resources, resource 7 requests more SI.

If according to the prior art, the terminal device can only send a request message for requesting SI to the network device through Msg1 as long as the network device configures PRACH resources for the terminal device, that is, resources indicated by the configuration information, herein, the request message for requesting SI sent by the terminal device to the network device is also referred to as a second message, since the resources configured by the configuration information are resources in Msg 1. In the embodiment of the present application, the network device may further indicate, through the configuration information, whether the network device supports the terminal device to send the second message for requesting SI through Msg3, that is, although the network device indicates the resource in Msg1 for the terminal device through the configuration information, the terminal device may also choose not to use, and send the second message for requesting SI to the network device using the resource in Msg3, which is more flexible. For example, 1 bit (bit) may be set in the configuration information to indicate whether the network device supports the terminal device to send the second message for requesting SI through Msg3, for example, the bit takes a value of "1" to indicate that the network device supports the terminal device to send the second message for requesting SI through Msg3, and the bit takes a value of "0" to indicate that the network device does not support the terminal device to send the second message for requesting SI through Msg 3. Of course, the indication by 1 bit is only an example, and the embodiment of the present application is not limited to how to specifically indicate, by the configuration information, whether the network device supports the end device to send the second message for requesting the SI through the Msg 3.

Alternatively, the configuration information may indicate whether the network device supports the terminal device to transmit information indicating the SI transmission method through Msg3, or the configuration information may indicate both whether the network device supports the terminal device to transmit information requesting SI through Msg3 and whether the network device supports the terminal device to transmit information indicating the SI transmission method through Msg 3. In both cases, information for requesting the SI and information for indicating the transmission method of the SI are decoupled. This will be described in detail later.

Alternatively, it may also indicate, not by the configuration information, whether the network device supports the terminal device to send the second message for requesting SI through Msg3 by using another message, for example, a message dedicated to indicate whether the network device supports the terminal device to send the second message for requesting SI through Msg3, or a message existing in the prior art, for example, SIB1, etc., which is not limited specifically.

And S52, the network equipment sends the configuration information, and the terminal equipment receives the configuration information from the network equipment.

After the network device generates the configuration information, the network device may send the configuration information, for example, the network device may send the configuration information carried in the SIB1, or may send the configuration information in other manners, which is not limited in this embodiment. For example, the network device may carry the configuration information in an SI Request configuration (SI-Request-Config) field in the SIB1, and specifically, may carry the configuration information in an SI Request resources (SI-Request resources) field in the SI-Request-Config field.

And S53, the terminal equipment determines the resource for requesting the system information according to the configuration information.

After the terminal device receives the configuration information, it can determine that the network device requests the resources configured by the SI for the terminal device. The content of the configuration information is described in S51 and will not be described in detail.

S54, the terminal device sends a second message to the network device, and the network device receives the second message from the terminal device, where the second message is used to request the SI. The second message is for requesting SI, e.g. one that is understood to include information for requesting SI.

The terminal device may determine, according to the configuration information, a resource configured by the network device for requesting the SI for the terminal device. For example, the terminal device receives configuration information as shown in fig. 6, then the second message may be sent to the network device via resource 1 in Msg1 if the terminal device is to request SI #1, or via resource 6 in Msg1 if the terminal device is to request SI # 7. Specifically, the terminal device may send the preamble to the network device through resource 1 in Msg1, and the network device may know that the terminal device is requesting SI #1 if the network device receives the preamble through resource 1 in Msg 1. That is, in fact, the terminal device may only send the preamble to the network device through different resources without sending the second message in the strict sense to the network device, and the network device may determine that the terminal device is requesting a certain SI or certain SIs according to the resource receiving the preamble.

Alternatively, if the network device indicates that the network device supports the terminal device to send the second message requesting SI to the network device via the Msg3 resource, the terminal device may send the second message to the network device via the Msg3 resource instead of using the Msg1 resource configured by the network device via the configuration information. In this case, specifically, whether the network device sends the second message to the network device through the resource in the Msg1 configured by the configuration information or sends the second message to the network device through the resource in the Msg3, the terminal device may be determined according to the actual situation.

For example, because the resources in Msg1 are relatively limited, if the terminal device is unable to carry more content in the second message if the second message is sent to the network device via the resources in Msg1, then the terminal device may choose to send the second message to the network device via the resources in Msg3 if more content is to be sent to the network device. For example, the terminal device may have a selection mechanism, when the terminal device requests the SI, if the number of bits occupied by the second message sent by the terminal device for requesting the SI is greater than or equal to the preset number, the terminal device may send the second message to the network device through the resource in the Msg3, otherwise, the terminal device may send the second message to the network device through the resource in the Msg1 configured by the network device. The preset number is, for example, the maximum number of bits that can be carried by the resource requesting the SI in Msg 1. Or, when the terminal device requests the SI, if the second message sent by the terminal device for requesting the SI needs to carry other information, the terminal device may send the second message to the network device through the resource in the Msg3, otherwise, the terminal device may send the second message to the network device through the resource in the Msg1 configured by the network device, where the other information is information other than information for requesting the SI. In this way, the information that the terminal device needs to send can be sent as much as possible, and when the information that the terminal device needs to send is not much, the information can be sent continuously through the resource in the Msg1, which also helps to save resources.

Specifically, the embodiment of the present application is not limited to how the terminal device selects whether to send the second message through the resource in the Msg3 or the resource in the Msg 1.

As an optional implementation manner, the second message sent by the terminal device for requesting the SI may also be used to indicate a sending manner of the SI requested by the second message, and for the second message to indicate the sending manner of the SI requested by the second message, it is understood that the second message includes information for indicating the sending manner of the SI requested by the second message. The transmission method of one SI may include: transmitting the SI in a current Modification Period (MP), or transmitting the SI in a next MP; and/or, the SI is transmitted in a unicast manner, or the SI is transmitted in a broadcast manner. Specifically, the sending mode of one SI may include sending the SI in the current MP, or sending the SI in the next MP; or, the transmission mode of one SI may include transmitting the SI in a unicast mode, or transmitting the SI in a broadcast mode; alternatively, the transmission manner of one SI may include transmitting the SI in the current MP, or transmitting the SI in the next MP, and transmitting the SI in a unicast manner, or transmitting the SI in a broadcast manner.

That is, when the terminal device sends the second message for requesting the SI to the network device, the terminal device may also tell the network device how the terminal device wants the network device to send the SI. For example, whether the terminal device wants the network device to send the SI at the current MP or the network device to send the SI at the next MP; alternatively, the terminal device may wish the network device to transmit the SI in a unicast manner or in a broadcast manner. For example, if the terminal device is anxious to obtain the requested SI, the terminal device may instruct the network device via the second message, so that the network device sends the SI at the current MP, so that the terminal device can obtain the SI as soon as possible, otherwise, if the terminal device is anxious to obtain the requested SI, the terminal device may instruct the network device via the second message, so that the network device sends the SI at the next MP, or, if the terminal device wants the network device to send the SI at the next MP, the terminal device may not instruct the network device via the second message, the network device may be, for example, pre-configured, and if the terminal device is not instructed, the network device may default to send the SI at the next MP. For another example, if the terminal device is in a position to acquire the requested SI urgently, the terminal device may instruct the network device through the second message, and allow the network device to transmit the SI in a unicast manner, considering that not all terminal devices may be in a position to acquire the SI urgently, and do not need to transmit the SI in a broadcast manner, so as to avoid interfering with other terminal devices, otherwise, if the terminal device is not in a position to acquire the requested SI urgently, the terminal device may instruct the network device through the second message, and allow the network device to transmit the SI in a broadcast manner, or, if the terminal device desires the network device to transmit the SI in a broadcast manner, the terminal device may instruct the network device through the second message, and the network device is, for example, preconfigured, and may default to transmit the SI in a broadcast manner if the terminal device does not receive an instruction.

Of course, the contents included in the transmission mode of the SI are only examples as described above, and the embodiments of the present application are not limited to how the terminal device determines the contents indicated by the second message.

The terminal device sends the second message to the network device, and the second message may be sent through the resource of Msg1, or, if the network device indicates the terminal device and the network device supports the terminal device to send the second message through the resource of Msg3, the terminal device may also send the second message through the resource of Msg 3.

If the terminal device sends the second message through the resource of Msg1, and the second message needs to indicate additional information, for example, to indicate whether the network device sends the requested SI at the current MP or at the next MP, the resource of Msg1 may be divided into different groups in advance through a protocol or by the network device, the resource indicated by one piece of record information belongs to one group, the resource indicated by the record information is different, which indicates that the groups to which the resources belong are different, and the network device is sent a preamble through different resource packets of Msg1, so as to inform the network device when the terminal device requests the network device to send the MP. For example, the Msg1 resources are divided into two groups, each group includes all the resources indicated by the configuration information, that is, the terminal device can request the corresponding SI no matter in which group's resources the second message is sent. Then if the end device sends Msg1 using the resources of the first group, it tells the network device that the end device wants the network device to send the requested SI at the current MP, and if the end device sends Msg1 using the resources of the second group, it tells the network device that the end device wants the network device to send the requested SI at the next MP, which is equivalent to indicating the sending of the SI by grouping. Of course, this is only one way to send the second message to the network device through the Msg1 resource, and in particular, the embodiment of the present application is not limited to how to specifically request the SI sending way when sending the second message through the Msg1 resource.

If the terminal device sends the second message through the Msg3 resource, as an implementation manner, the terminal device may carry the second message in a SI request radio resource control (SI request RRC) signaling in the Msg3, where the second message may be used to request a sending manner of the SI besides the SI, and certainly may not be required to request a sending manner of the SI, and is not limited specifically. The SI request RRC signaling is signaling used in the Msg3 to request SI, for example, one of the SI request RRC signaling is RRC system information request (rrcsystemminforequest) signaling.

In the second message sent by the terminal device for requesting the SI, if the second message further needs to request a sending mode of the SI, in this case, the content that the second message needs to carry is relatively large, and if the terminal device sends through the resource in the Msg1, the terminal device actually only sends the preamble to the network device, and the amount of information that can be carried is small. Therefore, considering the limited resource nature of Msg1, embodiments of the present application may also provide that if the terminal device sends the second message via the resource in Msg1, the second message may not require additional information, such as a SI-requested delivery method, and if the terminal device sends the second message via the resource in Msg3, the second message may require additional information, such as a SI-requested delivery method.

For example, if the default network device configures the terminal device with Msg1 resources, the terminal device can only send the second message to the network device via Msg1 resources, or if the network device informs the terminal device that the network device does not support the terminal device sending the second message requesting SI to the network device via Msg3, in both cases, the terminal device sends the second message to the network device via Msg1, and the second message does not need to request SI for sending. And if the network device informs the terminal device, the network device supports the terminal device to send a second message for requesting SI to the network device through Msg3, the terminal device may determine whether additional information needs to be requested from the network device via the second message, if additional information is required to be requested from the network device via the second message, such as a request for SI delivery, the terminal device may choose to send the second message to the network device via Msg3, the second message may be used to request the transmission mode of the SI, in addition to the SI, and if the terminal device considers that no additional information needs to be requested from the network device by the second message, then although the network device supports the end device sending the second message requesting SI to the network device via Msg3, the end device may still send the second message to the network device via Msg 1's resource configured by the network device via the configuration information.

In the above description, it is considered that if the terminal device wants to transmit other information, for example, information indicating the transmission mode of the SI, the terminal device carries both the information for requesting the SI and the other information, for example, the information indicating the transmission mode of the SI, in the second message, that is, the second message can be used for requesting the SI and can also be used for indicating the transmission mode of the SI. In the embodiment of the present application, the information for requesting the SI and the information for indicating the transmission mode of the SI may also be decoupled, for example, the information and the information may be carried in one message and transmitted together, or may not be carried in one message but transmitted through different messages. In this case, the configuration information may indicate whether the network device supports the terminal device to transmit information indicating the SI transmission method through the Msg 3. Then, if the configuration information indicates that the network device supports the terminal device to transmit information indicating the transmission method of SI through Msg3, the terminal device may transmit through Msg3 if it needs to transmit information indicating the transmission method of SI, in which case it is not limited whether the terminal device transmits information requesting SI through Msg1 or Msg 3. For example, since the network device sends the configuration information to the terminal device, the terminal device may send information requesting SI to the network device through the resource in Msg1 indicated in the configuration information, or the terminal device may carry the information requesting SI and the information indicating the transmission mode of SI in the second message and send through Msg3, or for example, the terminal device may carry the information requesting SI in the second message and carry the information indicating the transmission mode of SI in the third message, and then the third message may be sent through Msg3, and the second message may be sent through Msg1 or through Msg 3. Of course, the second message and the third message may also be regarded as the same message, and the same message is split and then sent through the Msg1 resource and the Msg3 resource, respectively, or the second message and the third message may also be regarded as different messages.

Or, if the information for requesting the SI and the information for indicating the transmission mode of the SI are carried in one message and transmitted together, or may not be carried in one message but transmitted through different messages, the configuration information indicates whether the network device supports the terminal device to transmit the information for requesting the SI through Msg3, and whether the network device supports the terminal device to transmit the information for indicating the transmission mode of the SI through Msg3, that is, the configuration information indicates the two information separately, and the terminal device may transmit the information for requesting the SI and the information for indicating the transmission mode of the SI according to the indication of the configuration information. For example, if the configuration information indicates that the network device supports the terminal device to transmit the second message for requesting SI through Msg3 and the network device supports the terminal device to transmit information for indicating the transmission mode of SI through Msg3, then the terminal device may transmit the information for requesting SI through Msg1 or Msg3, or may transmit the information for indicating the transmission mode of SI through Msg1 or Msg 3. For example, the terminal device may send information requesting SI and information indicating a transmission mode of SI via Msg1, may carry the two pieces of information in a second message and send them together in Msg1, or may carry the two pieces of information in different messages and send them separately in Msg 1; alternatively, the terminal device may send the information requesting the SI and the information indicating the transmission mode of the SI through the Msg3, may carry the two pieces of information in the second message and send them together in the Msg3, or may carry the two pieces of information in different messages and send them separately in the Msg 3; alternatively, the terminal device may transmit information indicating a transmission manner of SI through Msg1, and transmit information requesting SI through Msg3, and so on. As an alternative, because the content of the information for requesting SI may be less, the content of the information for indicating the transmission mode of SI may be more, and the resources in Msg1 are limited relative to the resources in Msg3, if the configuration information indicates that the network device supports the terminal device to transmit the information for requesting SI through Msg3 and the network device supports the terminal device to transmit the information for indicating the transmission mode of SI through Msg3, the terminal device may transmit the information for requesting SI through Msg1 and transmit the information for indicating the transmission mode of SI through Msg 3.

S55, the network device sends the first message to the terminal device, and the terminal device receives the first message from the network device, where the first message is used to indicate a sending mode of the system information.

After the terminal device sends the second message to the network device, the network device may also reply to the terminal device with a response message for the second message, which is also referred to as the first message herein. Wherein the network device can send the first message to the terminal device via Msg2 if the terminal device sends the second message to the network device via Msg 1's resources, or can send the first message to the terminal device via Msg4 if the terminal device sends the second message to the network device via Msg 3.

And S56, the terminal equipment determines the sending mode of the system information according to the first message.

In this embodiment of the present application, the first message is used to indicate a transmission mode of the SI, and the terminal device may determine the transmission mode of the SI indicated by the terminal device according to the first message. The transmission method of one SI may include: transmitting the SI in the current MP, or transmitting the SI in the next MP; and/or, the SI is transmitted in a unicast manner, or the SI is transmitted in a broadcast manner. The SI transmission method is described in S53, and will not be described in detail. In S53, the terminal device may request the SI transmission mode desired by the terminal device through the second message when sending the second message, and in S54, the network device sends a first message to the terminal device, where the network device tells the terminal device how the network device will send the SI to the terminal device at all times, and the subsequent network device sends the SI to the terminal device in the mode indicated by the network device in the first message when sending the SI to the terminal device. Then, the transmission mode of the SI indicated by the terminal device in the second message and the transmission mode of the SI indicated by the network device in the first message may be the same, for example, the transmission mode of the SI indicated by the terminal device in the second message and the transmission mode of the SI indicated by the network device in the first message both include transmitting the SI in the current MP; alternatively, the transmission mode of the SI indicated by the terminal device in the second message may be different from the transmission mode of the SI indicated by the network device in the first message, for example, the transmission mode of the SI indicated by the terminal device in the second message includes transmitting the SI in the current MP, and the transmission mode of the SI indicated by the network device in the first message includes transmitting the SI in the next MP.

In addition, the network device indicates the transmission mode of the SI in the first message, which does not depend on the terminal device necessarily requesting the network device to transmit the SI in the second message, that is, the terminal device requests the network device to transmit the SI through the second message, which is an optional implementation, or the terminal device may not request the network device to transmit the SI, for example, the second message sent by the terminal device is not used for requesting the transmission mode of the SI, and the network device may indicate the transmission mode of the SI to the terminal device in the first message. That is, if the terminal device requests the network device to send the SI in the second message, the network device may determine, according to the second message of the terminal device, a sending mode of the SI actually sent by the network device, that is, determine a sending mode of the SI indicated in the first message, and if the terminal device does not request the sending mode of the SI from the network device, the sending mode of the SI indicated in the first message by the network device may be the sending mode of the SI default by the network device. For example, the default mode of sending the SI by the network device includes sending the requested SI in the next MP and/or sending the SI by broadcasting, that is, the default mode of sending the SI by the network device includes sending the requested SI in the next MP, or sending the SI by broadcasting, or sending the requested SI in the next MP and sending the SI by broadcasting. Of course, the network device indicates the transmission mode of the SI through the first message, which is also an optional embodiment, or the network device may only send the first message, and the first message does not indicate the transmission mode of the SI, and is not limited specifically.

It was mentioned in the foregoing that the SI transmission mode includes which MP the SI is transmitted in, and the so-called MP is a time period during which the SI is kept unchanged. If the SI needs to be changed, the network device needs to notify the terminal device in advance in one MP, the SI will change, and then in the next MP, the network device can send the updated SI. However, in the prior art, after the network device receives the second message of the terminal device for a certain SI and sends the first message to the terminal device, it is not clear whether the network device sends the requested SI at the current MP or sends the requested SI at the next MP. For example, referring to fig. 9, after the network device sends the first SIB1 to the terminal device, the terminal device may send the second message to the network device in one SIB1 period, and the network device sends the first message to the terminal device in the next SIB1 period, and the terminal device does not know whether the SI should be detected in the current MP or the next MP, which may result in an increase in the number of blind detections of the terminal device if the terminal device detects in both the current MP and the next MP, and may result in the terminal device being unable to receive the SI if the terminal device detects in only one of the MPs but the network device sends the SI in the other MP.

In view of this, in this embodiment of the present application, the network device may indicate, to the terminal device through the first message, whether the network device sends the SI in the current MP or sends the SI in the next MP, so that the terminal device may specify at which position or positions the SI should be detected, thereby reducing the number of blind detections of the terminal device, and also improving the success rate of receiving the SI. In addition, the terminal device may indicate the transmission mode of the SI desired by the terminal device to the network device in the second message, and the network device may also transmit the SI according to the transmission mode desired by the terminal device, so that the transmission of the SI more meets the requirement of the terminal device.

And S57, the network equipment sends the SI requested by the terminal equipment to the terminal equipment, and the terminal equipment receives the SI from the network equipment.

Wherein, if the network equipment indicates the transmission mode of the SI through the first message, the network equipment transmits the SI according to the transmission mode. For example, the network device indicates, through the first message, that the SI is sent in the current MP and sent in the unicast manner, the network device may execute the SI in the current MP when performing S55, and send the SI in the unicast manner.

The process ends.

Among them, S51 to S53 may be regarded as one portion, for example, referred to as a first portion, S54 may be regarded as another portion, for example, referred to as a second portion, S55 to S56 may be regarded as another portion, for example, referred to as a third portion, and these three portions may be independent of each other. For example, for the first part, it can be applied in combination with the second part, or it can be applied in combination with the second part and the third part, or it can be applied separately, and the same applies for the second part and the third part.

As a first example, the first part is applied separately, then the second message sent by the terminal device to the network device in S54 may not be used to indicate the sending mode of SI, and is only used to request SI, and the first message sent by the network device to the terminal device in S55 may not be used to indicate the sending mode of SI, and is only used as an acknowledgement for the second message, and it may be considered that S51 to S53 are optional steps, and S54, S55, and S57 after being changed are only optional steps, and S56 may not be necessarily executed.

As a second example, if the second part is applied separately, then the second message sent by the terminal device may request the sending mode of the SI, then the configuration information generated by the network device in S51 and the configuration information sent by the network device in S52 may be the same as the configuration information generated and sent by the network device in the prior art, and the first message sent by the network device to the terminal device in S55 may also be not used for indicating the sending mode of the SI, but only as an acknowledgement to the second message. And it can be considered that S54 is a mandatory step, S55, S53, S57, and changed S51 and S52 are only optional steps, and S56 may not be necessarily performed. For configuration information generated and sent by a network device in the prior art, reference may be made to fig. 1 or fig. 2, which is not described in detail.

As a third example, if the third part is applied separately, the configuration information generated by the network device in S51 and the configuration information sent by the network device in S52 may be the same as the configuration information generated and sent by the network device in the prior art, and the second message sent by the terminal device to the network device in S54 may not be used for indicating the sending mode of the SI, but is only used for requesting the SI. It is also considered that S55 to S56 are optional steps, and S57 and the changed S51, S52, S53 and S54 are optional steps. For configuration information generated and sent by a network device in the prior art, reference may be made to fig. 1 or fig. 2, which is not repeated.

As a fourth example, the first part is applied in combination with the third part, then the second message sent by the terminal device to the network device in S54 may not be used to indicate the sending mode of the SI, but is only used to request the SI, and S51 to S53 may be considered as optional steps, and S54 to S57 may be considered as optional steps, or S55 to S56 may be considered as optional steps, and the others are all optional steps.

As a fifth example, if the first part is applied in combination with the second part, the first message sent by the network device to the terminal device in S55 may not be used to indicate the sending mode of the SI, but only serve as an acknowledgement to the second message. S51 to S54 may be regarded as optional steps, and S55 to S57 may be optional steps, or S51 to S53 may be regarded as optional steps, and S54 to S57 may be optional steps, or S54 may be regarded as optional steps, and the others are optional steps.

As a sixth example, the first part, the second part and the third part are applied in combination, then S51 to S53 may be considered as indispensable steps, and S53 to S57 as optional steps, or S54 to S56 may be considered as indispensable steps, and S51, S52, S53 and S57 as optional steps, or S55 to S56 may be considered as essential steps, and S51, S52, S53, S54 and S57 as optional steps. The optional steps are steps that are not necessarily performed.

The above combinations are just a few examples, and any two of the first, second, and third portions may be combined, and so on with respect to the other combinations of the first, second, and third portions.

In the configuration information of the embodiment of the application, information does not need to be recorded for all SI in a single list, so that the bit number of the configuration information is effectively reduced, and resource saving is facilitated.

When the communication apparatus is a terminal device, fig. 18 shows a schematic structural diagram of a simplified terminal device. For ease of understanding and illustration, in fig. 18, the terminal device is exemplified by a mobile phone.

It should be noted that some kinds of terminal devices may not have input/output devices.

When data needs to be sent, the processor performs baseband processing on the data to be sent and outputs baseband signals to the radio frequency circuit, and the radio frequency circuit performs radio frequency processing on the baseband signals and sends the radio frequency signals to the outside in the form of electromagnetic waves through the antenna. When data is sent to the terminal equipment, the radio frequency circuit receives radio frequency signals through the antenna, converts the radio frequency signals into baseband signals and outputs the baseband signals to the processor, and the processor converts the baseband signals into the data and processes the data. For ease of illustration, only one memory and processor are shown in FIG. 18. In an actual end device product, there may be one or more processors and one or more memories.
