Background

In a fifth Generation (5th-Generation, 5G) mobile communication System, System Information (SI) is divided into two major categories, one being Minimum System Information (Minimum SI) and the Other being Other System Information (Other SI). Other SI is divided into Common system information (Common SI), which is system information shared by several cells, and Cell Specific SI, which is system information for one Cell, according to the effective range. The Minimum SI is sent to a User Equipment (UE) in a periodic broadcast manner, the Other SI requires the UE to request the base station, and the UE may request the Other SI from the base station through a random access procedure.

However, the current communication protocol specifies that the UE can only initiate one random access procedure at the same time, and if the UE needs to request system information from the base station and establish an RRC connection with the base station during one random access procedure, the UE cannot know how to communicate with the base station, and thus cannot implement the request of system information and the establishment of the RRC connection.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be understood that the technical solutions of the embodiments of the present application may be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS) or a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a 5G System, or a New Radio (NR) System.

In the embodiment of the present application, the Terminal device may include, but is not limited to, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a Mobile phone (Mobile Telephone), a User Equipment (UE), a handset (handset), a portable device (portable Equipment), a vehicle (vehicle), and the like, and the Terminal device may communicate with one or more core networks through a Radio Access Network (RAN), for example, the Terminal device may be a Mobile phone (or referred to as a "cellular" phone), a computer with a wireless communication function, and the Terminal device may also be a portable, pocket, handheld, computer-embedded, or vehicle-mounted Mobile apparatus.

The network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of devices having a base station function may differ. For example, in an LTE network, referred to as an Evolved node B (eNB or eNodeB), in a third Generation (3rd Generation, 3G) network, referred to as a node B (node B), and so on.

It should be noted that, when describing a specific embodiment, the sequence numbers of the processes do not mean the execution sequence, and the execution sequence of the processes should be determined by the functions and the internal logic of the processes, and should not constitute any limitation to the implementation process of the embodiment of the present application.

It should be further noted that, in this embodiment of the application, when the terminal device needs to establish the RRC connection, the procedure for establishing the RRC connection includes an RRC connection establishment procedure or an RRC connection reestablishment procedure or an RRC connection establishment procedure triggered by an RRC connection recovery (Resume) requirement, where the RRC connection establishment procedure triggered by the RRC connection recovery (Resume) requirement is used for the terminal device to transition from the Inactive state (Inactive) to the connected state. In describing the specific embodiment, the RRC connection establishment procedure is taken as an example for description convenience only, and does not limit the scope of the embodiments of the present application in any way.

Fig. 1 illustrates a method of wireless communication according to one embodiment of the present application. As shown in fig. 1, the method 100 includes:

s101, determining a target message for carrying a System Information (SI) request, wherein the target message is a message1 or a message 3, and the SI request is used for requesting network equipment to send SI.

The Message (Message)1 in S110 may correspond to Message1 in a contention based random access procedure in the existing communication system, or may correspond to Message1 in a non-contention based random access procedure in the existing communication system. The Message (Message)3 in S110 may correspond to Message 3 in a contention based random access procedure in the existing communication system.

Alternatively, the "SI request" in S110 may also be referred to as an "SI request message".

Alternatively, the terminal device may determine a target message for carrying a System Information (SI) request according to the configuration of the network device. For example, the network device may indicate in Minimum system information (Minimum SI) periodically sent to the terminal device a target message that the terminal device can use for carrying SI requests. Or the terminal device may determine the target message for carrying the SI request according to the type of SI to be requested. For example, assuming that there are 9 types of SIs (SI 1-SI 9) in the communication system, the network device and the terminal device may have a predetermined agreement or protocol to specify that the target Message for carrying the SI request for requesting SI 1-SI 3 is Message1, and the target Message for carrying the SI request for requesting SI 4-SI 9 is Message 3. And if the terminal equipment determines that the SI required to be requested is SI 5, the terminal equipment determines that the target Message is Message 3.

In this embodiment of the present application, optionally, one SI may include one or more System Information Blocks (SIBs), or one SI may be used to indicate one or more SIBs, and it may also be understood that the SI and the SIBs have a corresponding relationship. Taking the above 9 types of SI as an example, it is assumed that SI 1 corresponds to SIB1, SI 2 corresponds to SIB 2 and SIB 3, SI 3 corresponds to SIB 4 and SIB 5, SI 4 corresponds to SIB 6, SI 5 corresponds to SIB 7, SI 6 corresponds to SIB 8, SI 7 corresponds to SIB 9 and SIB 10, SI 8 corresponds to SIB11, and SI9 corresponds to SIB 12 and SIB 13. If the SI request sent by the terminal device is used to request the network device to send SI 7, the network device may know that SIB 9 and SIB 10 need to be sent to the terminal device according to the above correspondence. Or if the SI request sent by the terminal device is used to request the network device to send the SIB11, the network device may know that SI 8 needs to be sent to the terminal device according to the above correspondence.

S102, according to the target message and the time of the radio resource control RRC connection needing to be established, the operation related to the establishment of the RRC connection is executed.

The wireless communication method of the embodiment of the application enables the terminal device to communicate with the network device through a proper communication flow when the terminal device needs to request the network device for system information and establish RRC connection with the network device during a random access process, thereby realizing the request of the system information and the establishment of the RRC connection.

Fig. 2 illustrates a method of wireless communication according to a particular embodiment of the present application. As shown in fig. 2, the method 200 includes:

s201, the terminal device determines that a target Message for carrying the SI request is Message1 or Message 3.

It can be understood that the terminal device determines the target message for carrying the SI request when determining that the SI needs to be requested from the network device.

S202, the terminal device sends Message1 (i.e., random access preamble) to the network device.

Optionally, the random access procedure triggered in S202 is a random access procedure for requesting the network device to send the SI.

S203, the terminal device starts receiving the Message2 (i.e., the random access response) sent by the network device.

And S204, the terminal equipment sends the Message 3 to the network equipment.

S205, the terminal device starts monitoring Message 4.

S206, when the uplink data of the terminal equipment arrives, the RRC connection needs to be established.

Optionally, as an example, the time required to establish the RRC connection is before the terminal device successfully receives the Message4, which may also be understood as: the time required to establish the RRC connection is before the terminal device starts receiving the Message4, or the time required to establish the RRC connection is during the process of receiving the Message4 by the terminal device. If the time required to establish the RRC connection is before the terminal device starts receiving the Message4, in S206, the uplink data of the terminal device may arrive at the time when the terminal device starts monitoring the Message4, or may arrive during the process when the terminal device monitors the Message 4.

S207, the terminal device abandons the Message4 reception and triggers a random access procedure for establishing an RRC connection.

It should be understood that the target Message for carrying the SI request, which is determined in S201 by the terminal device, is Message1 or Message 3, and the terminal device may select to carry the SI request in Message1 in S202 or may select to carry the SI request in Message 3 in S204. Or the network device may instruct the terminal device to carry the SI request in Message1 or Message 3 through the configuration information.

It is understood that if the time required to establish the RRC connection in S206 is before the terminal device starts receiving the Message4, the terminal device does not trigger the process of receiving the Message 4. Specifically, if the uplink data of the terminal device arrives at the time of starting to monitor Message4 or during the process of monitoring Message4, the abandoning of the reception of Message4 in S207 means that the terminal device does not monitor Message4 or stops monitoring Message 4. If the time required to establish the RRC connection in S206 is during the process of receiving the Message4 by the terminal device, abandoning the reception of the Message4 in S207 means that the terminal device stops the process of receiving the Message 4.

Optionally, as an example, in S207, if the terminal device abandons the reception of the Message4 and triggers the random access procedure for establishing the RRC connection, the terminal device may simultaneously carry the RRC connection establishment request Message and the SI request in the Message 3 in the random access procedure for establishing the RRC connection. Or the terminal device may carry an RRC connection establishment request Message in Message 3 in a random access procedure for establishing an RRC connection, where the RRC connection establishment request Message includes an SI request.

Optionally, as another example, in S207, after the terminal device successfully receives the Message4, the terminal device triggers a random access procedure for establishing the RRC connection, where successful reception of the Message4 by the terminal device means that the terminal device triggers a procedure of receiving the Message4, and ends the procedure when the reception of the Message4 is completed. What kind of operation the terminal device specifically executes in S207 may be a network device and a terminal device implementing convention, or may be configured by the network device. For example, if the network device indicates, through the configuration information, that the priority for establishing the RRC connection is higher than the priority for requesting the SI, the terminal device performs an operation of aborting reception of the Message4 and triggering a random access procedure for establishing the RRC connection in S207. The configuration information may be carried in minimum system information that is periodically sent to the terminal device by the network device.

Optionally, as another example, the time of arrival of the uplink data of the terminal device is before the time of successful reception of the Message2 by the terminal device, or the time of the need to establish the RRC connection is before the time of successful reception of the Message2 by the terminal device. The time required to establish the RRC connection before the terminal device successfully receives the Message2 may also be understood as: the time required to establish the RRC connection is before the terminal device starts receiving the Message2, or the time required to establish the RRC connection is during the process of receiving the Message2 by the terminal device. That is, the execution order of S206 is between S202 and S203. In this case, in S207, the terminal device triggers a random access procedure for establishing an RRC connection after successfully receiving the Message 4.

Optionally, as another example, the arrival time of the uplink data of the terminal device is after the terminal device successfully receives the Message2 and before the terminal device sends the Message 3 to the network device, where the successful reception of the Message2 by the terminal device means that the terminal device triggers a process of receiving the Message2, and ends the process when the reception of the Message2 is completed. That is, the execution order of S206 is between S203 and S204. In this case, if the resource of the Message 3 is not limited, the terminal device may simultaneously carry the SI request and the RRC connection establishment request Message in the Message 3, and then the terminal device monitors the Message4 in S205 and receives the Message4 in S207. The terminal device may determine whether the resource of Message 3 is limited according to the resource size indicated by the information in Message 2. For example, if the resource size indicated by the information in Message2 is larger than the uplink resource required for transmitting the SI request and the RRC connection establishment request Message, the terminal device determines that the resource of Message 3 is not limited.

Fig. 3 illustrates a method of wireless communication according to another particular embodiment of the present application. As shown in fig. 3, the method 300 includes:

s301, the terminal device determines that the target Message for carrying the SI request is Message1 or Message 3.

S302, the terminal device sends Message1 to the network device.

S303, when the uplink data of the terminal device arrives, the RRC connection needs to be established.

Optionally, as an example, the time required to establish the RRC connection is before the terminal device successfully receives the Message2, and it may be understood that the time required to establish the RRC connection is before the terminal device starts receiving the Message2, or the time required to establish the RRC connection is in the process of receiving the Message2 by the terminal device.

Optionally, as another example, the time when the uplink data of the terminal device arrives is before the terminal device sends Message1 to the network device, that is, the time when the RRC connection needs to be established is before the terminal device sends Message1 to the network device. That is, the execution order of S303 precedes S302.

S304, the terminal device abandons the Message2 reception and triggers a random access procedure for establishing an RRC connection.

It is understood that if the time required to establish the RRC connection in S303 is before the terminal device starts receiving Message2, abandoning the reception of Message2 in S304 means that the terminal device does not trigger the process of receiving Message 2. If the time required to establish the RRC connection in S303 is in the process of the terminal device receiving the Message2, abandoning the Message2 in S304 means that the terminal device stops the process of receiving the Message 2.

Optionally, as an example, in S304, if the terminal device abandons the reception of the Message2 and triggers the random access procedure for establishing the RRC connection, the terminal device may simultaneously carry the RRC connection establishment request Message and the SI request in the Message 3 in the random access procedure for establishing the RRC connection. Or the terminal device may carry an RRC connection establishment request Message in Message 3 in a random access procedure for establishing an RRC connection, where the RRC connection establishment request Message includes an SI request.

Optionally, in S301, if the target Message determined by the terminal device is Message1 corresponding to a non-contention based random access procedure in an existing communication system, the terminal device carries an SI request in the Message 1. Or, in S301, if the target Message determined by the terminal device is Message1 corresponding to a contention-based random access procedure in the existing communication system, the terminal device carries an SI request in the Message 1. Or, in S301, if the target Message determined by the terminal device is Message 3 corresponding to a contention-based random access procedure in an existing communication system, and the Message 3 is not allowed to simultaneously carry the RRC connection establishment request Message and the SI request, or only the Message 3 is allowed to carry the SI request, the terminal device carries the SI request in the Message 3.

Optionally, as an example, if in S301, the target Message determined by the terminal device is Message1 in a non-contention based random access procedure corresponding to the existing communication system, in S304, after the terminal device successfully receives Message2, the terminal device triggers a random access procedure for establishing an RRC connection, where successful reception of Message2 by the terminal device means that the terminal device triggers a procedure of receiving Message2, and ends the procedure when the reception of Message2 is completed.

It should be noted that, similar to the method 200, what kind of operation is specifically performed by the terminal device in S304 in the method 300 may be predetermined by the network device and the terminal device, or may be configured by the network device.

Fig. 4 is a method of wireless communication according to yet another embodiment of the present application. As shown in fig. 4, the method 400 includes:

s401, the terminal device determines that the target Message for bearing the SI request is Message 3.

S402, the terminal device sends Message1 to the network device.

It should be noted that, if the terminal device needs to establish the RRC connection before S402, the Message1 sent by the terminal device in S402 may trigger a random access request procedure for requesting SI from the network device, and may also trigger a random access request procedure for establishing the RRC connection.

S403, the terminal device starts receiving the Message2 sent by the network device.

S404, the terminal device needs to establish an RRC connection.

Optionally, the time that the terminal device needs to establish the RRC connection is before the terminal device starts to receive the Message2 sent by the network device, or the time that the terminal device needs to establish the RRC connection is after the terminal device starts to receive the Message2 sent by the network device and before the terminal device sends the Message 3 to the network device. In summary, before the terminal device sends Message 3 to the network device, the terminal device needs to both request SI from the network device and establish an RRC connection.

S405, if the resource of the Message 3 is limited, the terminal equipment sends the Message 3 only carrying the RRC connection establishment request Message.

Optionally, in S405, the terminal device determines whether the resource of Message 3 is limited according to the resource size indicated by the information in Message 2. For example, if the resource size indicated by the information in Message2 is smaller than the uplink resource required for transmitting the SI request and the RRC connection establishment request Message, the terminal device determines that the resource of Message 3 is limited. Or the network device carries indication information in the minimum system information periodically sent to the terminal device, where the indication information indicates whether the resource of the Message 3 is limited, and the limitation of the resource of the Message 3 may be understood as that the Message 3 can only carry an RRC connection establishment request Message or an SI request.

It can be understood that, if in S405, the terminal device sends the Message 3 carrying only the RRC connection establishment request Message to the network device, after the terminal device sends the Message 3 to the network device, the terminal device needs to monitor and start to receive the Message4 sent by the network device when the monitoring is successful. And after the terminal device successfully receives the Message4 sent by the network device, the terminal device may trigger a random access procedure for requesting the SI from the network device.

Optionally, as an embodiment, in S405, if the resource of the Message 3 is limited, the terminal device sends the Message 3 carrying only the SI request to the network device. In this case, after the terminal device transmits the Message 3 to the network device, the terminal device listens and starts receiving the Message4 transmitted by the network device when the listening is successful. After successfully receiving the Message4, the terminal device triggers a random access procedure for establishing an RRC connection.

It should be noted that, similar to the methods 200 and 300, what operation is specifically performed by the terminal device in S405 in the method 400 may be predetermined by the network device and the terminal device, or may be configured by the network device.
