FIG. 2 is an exemplary flowchart of a method for allocating a temporary identifier of a wireless network according to an embodiment of the present invention. In a specific implementation, the method 200 may be performed by the terminal devices 108-122 in FIG.

Step 202: The terminal device sends a random access request, where the random access request carries type information of the terminal device, where the type information is used to indicate a type of the terminal device.

Step 204: The terminal device receives a random access response, where the random access response carries a group radio network temporary identifier RNTI of the group in which the terminal device is located, where the group RNTI is allocated by the base station according to the type of the terminal device, The group RNTI is used to indicate a group of terminal devices, the group of terminal devices are of the same type, and the terminal device is one of the group of terminal devices.

According to the technical solution provided by the embodiment of the present invention, the terminal device sends a random access request, where the random access request carries the type information of the terminal device, where the type information is used to indicate the type of the terminal device, and the base station is based on the The type of the terminal device is a radio network temporary identifier (RNTI) of the group in which the terminal device is located, and the base station carries the group RNTI in a random access response and sends the signal to the terminal device. It can be seen that the terminal device can obtain the group RNTI in the access process, which creates conditions for the base station to implement batch control on a group of terminal devices at an earlier stage.

It should be noted that the random access request sent by the terminal device may be a random access request (Random Access Request) sent by the terminal device during random access in the Long Term Evolution (LTE), the random access request. Carry information such as random access preamble. In the technical solution provided by the embodiment of the present invention, the type information of the terminal device is carried in the random access request, and after receiving the random access request, the base station sends a random access response (Random Access Response) to the terminal device, The random access response includes a group radio network temporary identifier RNTI of the group in which the terminal device is located. It can be seen that the terminal device can obtain the group RNTI allocated by the base station for the random access process.

In a possible design, the type of the terminal device includes at least one of a device type and a service type. The device type is used to distinguish different types of terminal devices. For example, a smart phone and a smart meter are two different types of devices, and the device types are different. In a specific implementation process, the smart phone carries its serial number (IMEI number). The type information is sent to the base station, and the smart meter carries its serial number in its type information and sends it to the base station. The base station can distinguish the device types of the two terminal devices by the serial number of the smart phone and the serial number of the smart meter. The service type refers to the type of service initiated by the terminal device or the type of service to be initiated, such as a highly reliable small data volume service, a low latency large data volume service, etc., and different service types are indicated by the service type identifier, in a specific implementation process. The terminal device carries the service type identifier in the type information and sends the information to the base station, and the base station can distinguish different services according to the service type identifier.

In a possible design, the base station allocates a group RNTI to the group in which the terminal device is located according to the type of the terminal device, and the packet of the terminal device has been determined according to the type of the terminal device in advance, and the base station receives the type information of the terminal device, and then the terminal The device is assigned to the corresponding group and the group RNTI is assigned to the group in which the terminal device is located. For example, when the type of the terminal device is a device type, the base station may allocate a group RNTI to the group in which the terminal device is located according to the device type of the terminal device; when the type of the terminal device is a service type, the base station may be based on the service type of the terminal device. Assign a group RNTI to the group where the terminal device is located. It should be noted that, when the type information of the terminal device includes the device type and the service type, the base station may choose to allocate a group RNTI for the group where the terminal device is located according to the device type, and may also select a group for the group where the terminal device is located according to the service type. The RNTI, in a specific implementation process, the base station may select a mode for allocating a group RNTI according to actual needs (such as but not limited to the performance of the communication system), and is not limited herein.

In this case, the group RNTI may be allocated by the base station according to a correspondence between a type and a group RNTI and a type of the terminal device. Here, the correspondence between the type and the group RNTI may be determined by the communication protocol, or may be determined according to the performance requirements of the actual system. In this case, the type and the group RNTI may be one-to-one correspondence, or one type may correspond to multiple groups of RNTIs. When the type corresponds to the group RNTI, the base station determines the type of the terminal device, that is, the terminal device can be allocated a corresponding group RNTI; when one type corresponds to multiple groups of RNTIs, the base station determines the terminal device type, which can be One of the plurality of group RNTIs corresponding to the terminal device type is allocated to the terminal device, and one type corresponds to the plurality of group RNTIs, which can increase the flexibility of the group RNTI configuration, and facilitate the base station to select according to different system performance requirements. It should be noted that the base station allocates the same group RNTI for each terminal device in the same group.

In a possible design, after receiving the type information of the terminal device, the base station may group the terminal device based on the type information, and then allocate the group RNTI to the grouped terminal device. For example, when the type of the foregoing terminal device is a device type, the base station groups the terminal devices according to the device type, and allocates a group RNTI to the terminal device. When the type of the terminal device is a service type, the base station groups the terminal devices according to the service type, and allocates a group RNTI to the terminal device. It should be noted that when the service type of the terminal device changes, the base station may re-group the terminal device according to the service type of the terminal device, and allocate a new group RNTI to the terminal device. When the type information of the terminal device includes the device type and the service type, the base station may group the terminal devices based on the foregoing two types, and may also group the terminal devices based on one type. For example, the base station may first perform the device type according to the device type. The terminal device performs grouping, and then groups the terminal devices in each group according to the service type, and then allocates the group RNTI to the grouped terminal device. In a specific implementation process, the base station can select a policy for assigning the group RNTI according to actual needs. No restrictions. In a specific implementation process, the base station assigns a group RNTI to the terminal device based on the packet, which may be, for example but not limited to, randomly generating a sequence in a data space and assigning the sequence as a group RNTI to the terminal device, or in a predetermined manner. A group RNTI is randomly selected from the group RNTI list and allocated to the terminal device. It should be noted that the base station allocates the same group RNTI for each terminal device in the same group.

Step 302: The base station receives a random access request from the terminal device, where the random access request carries type information of the terminal device, where the type information is used to indicate the type of the terminal device.

Step 304: The base station sends a random access response, where the random access response carries a group radio network temporary identifier RNTI of the group in which the terminal device is located, where the group RNTI is allocated by the base station based on the type of the terminal device. The group RNTI is used to indicate a group of terminal devices, the group of terminal devices are of the same type, and the terminal device is one of the group of terminal devices.

The terminal device, the group downlink control information is directed to the group of terminal devices, that is, the base station controls the group of terminal devices by using a group of downlink control information. For example, the group downlink control information may include an uplink scheduling instruction, a modulation and coding scheme, and the like, and the base station sends the group downlink control information to the terminal device after generating the group downlink control information.

The other specific technical content involved in the foregoing method 300 has been clearly described above with reference to the accompanying drawings, such as but not limited to the above method 200 and FIG. 2, and thus will not be further described herein.

It can be seen that the base station receives the random access request from the terminal device, where the random access request carries the type information of the terminal device, the type information is used to indicate the type of the terminal device, and the base station is based on the terminal device. The type is a group in which the terminal device is located, and the group radio network temporary identifier RNTI is allocated, and the base station carries the group RNTI in a random access response and sends the packet to the terminal device. It can be seen that the terminal device can obtain the group RNTI in the access process, which creates conditions for the base station to implement batch control on a group of terminal devices at an earlier stage.

FIG. 4 is an exemplary flowchart of an information transmission method 400 according to an embodiment of the present invention. In a specific implementation, the method 400 may be performed by the terminal devices 108-122 in FIG.

Step 402: The terminal device receives group downlink control information from the base station.

Step 404: The terminal device performs an operation corresponding to the group downlink control information when determining that the group radio network temporary identifier RNTI of the group is the same as the group radio network temporary identifier RNTI carried in the group downlink control information, where The group RNTI of the group in which the terminal device is located is allocated by the base station based on the type of the terminal device, and the group RNTI is used to indicate a group of terminal devices, the terminal devices are of the same type, and the terminal device is One of a group of terminal devices.

According to the technical solution provided by the embodiment of the present invention, the terminal device receives the group downlink control information from the base station, and the terminal device determines the group radio network temporary identifier RNTI of the group in which the group is located and the group radio network temporary identifier RNTI carried in the group downlink control information. When the same operation is performed, the terminal device can perform the operation corresponding to the group downlink control information, and the terminal device can use the group RNTI to receive the group downlink control information sent by the base station to each terminal device of the group in which the terminal device is located, that is, the base station sends one piece for each terminal device in the same group. The downlink control information can be reduced, reducing the number of messages, thereby improving the efficiency of the network.

It should be noted that the group RNTI of the group in which the terminal device is located may be indicated by a field in the group downlink control information, or may be a cyclic redundancy check code in the group downlink control information by the group RNTI of the group in which the terminal device is located (Cyclic). Redundancy Check, CRC) is scrambled to indicate. For example, when the group RNTI of the group in which the terminal device is located is indicated by a field in the group downlink control information, the terminal device may determine the group radio network temporary identifier RNTI of the group in which the group is located and the group downlink control by determining the content of the foregoing field. Whether the group radio network temporary identifier RNTI carried in the information is the same. When the group RNTI of the group in which the terminal device is located is indicated by scrambling the Cyclic Redundancy Check (CRC) in the group downlink control information, the terminal device uses the group downlink control information after receiving the group. The RNTI of the group is used to descramble the CRC in the downlink control information of the group, and the descrambling success can determine the group radio network temporary identifier RNTI of the group in which the group is located and the group radio network temporary identifier RNTI carried in the group downlink control information. the same.

In a possible design, before the terminal device receives the group downlink control information from the base station, the terminal device sends a random access request, where the random access request carries type information of the terminal device, and the type information The terminal device is configured to receive a random access response, and the random access response carries a group radio network temporary identifier RNTI of the group in which the terminal device is located, where the group RNTI is based on the base station The type of terminal device is assigned. The base station assigns a group radio network temporary identifier RNTI to the terminal device. For example, but not limited to the method 200 above, it should be noted that the base station allocates a group radio network temporary identifier RNTI for the terminal device, and may also be performed at other stages in the communication process. For example, after establishing a Radio Resource Control (RRC) connection.

In one possible design, the type includes at least one of a device type and a service type. For a process in which the base station allocates a group radio network temporary identifier RNTI to the terminal device based on the type of the terminal device, reference may be made to the foregoing method 200, and details are not described herein again.

In a possible design, the terminal device receives the group downlink control information from the base station, where the terminal device receives the group downlink control information by using a group downlink control channel. In this case, the group downlink control channel carries the group downlink control information, and the group downlink control information may be obtained by the group radio network temporary identifier RNTI scrambling, where the group radio network temporary identifier RNTI is used to indicate a group of terminal devices. . In other words, the base station transmits the same downlink control information for a group of terminal devices through the group radio network temporary identifier RNTI. When receiving the group downlink control information, the terminal device performs blind detection in the search space of the group downlink control channel by using the group radio network temporary identifier RNTI of the group in which the group is located. If the group RNTI of the group in which the group is located is detected, the terminal device can determine the receiving. The downlink control information of the group is the downlink control information sent to itself, and then the operation corresponding to the group downlink control information is performed. It can be seen that when the terminal device receives the downlink control information through the group downlink control channel, the terminal device may perform blind detection in the user equipment UE specific search space of the physical downlink control channel (PDCCH) to receive the downlink control. The information reduces the number of blind checks and reduces the processing delay and power consumption of the terminal device.

In a possible design, the group downlink control channel is a control channel different from the physical downlink control channel PDCCH, that is, the group downlink control channel is a newly defined control channel, and the group of downlink control channels are separately planned. The downlink physical resource, that is, multiple resource elements (RE elements) that are separately planned to carry the group downlink control information.

In a possible design, the group downlink control channel is a physical downlink control channel PDCCH, the PDCCH includes a group search space, and the group downlink control information is included in the group search space, where the group search The space is a search space different from the public search space and the user equipment UE specific search space. For example, the set of search spaces may be a search space for a group of user equipments for transmitting control information for user equipments within the same group, in other words, the user equipment may be in the search space by the group RNTI of the group in which they are located. Searching for the control information sent by the base station, the set of search spaces may be a search space with a high degree of aggregation, for example, may be a search space with a degree of aggregation of 6 or a degree of aggregation of 12 in the PDCCH. It is to be noted that the above description of the group search space is only an example. In the specific implementation process, the group search space may be set according to the actual needs of the communication system, which is not limited herein.
