Description

Method and device for processing scheduling information, computer storage medium

Technical field

The present invention relates to information transmission technologies in the field of communications, and in particular, to a method and device for processing scheduling information, and a computer storage medium.

Background technique

With the rapid development of Internet technology in mobile communication systems and the large-scale construction of wireless cities around the world, broadband has become the development trend of the entire wireless communication. Correspondingly, the business requirements for broadband communication of trunking communication systems are also more significant. The Long Term Evolution System (LTE), as a quasi-4G wireless communication system, can meet the development needs of broadband communication of trunking communication systems, and thus derives an LTE-based trunking communication system, which has both LTE public network and trunking communication. The function of the system.

In the prior art, on the Physical Downlink Control Channel (PDCCH), the basic unit of Downlink Control Information (DCI) is a Control Channel Element (CCE). CCE is a time-frequency resource unit of LTE. Before the transmission, the scheduling information group of different DCI formats is first added with Cyclic Redundancy Check (CRC), and the corresponding Group Radio Network Temporary Identifier (G-RNTI) is added. The CRC is scrambled. Then, rate matching processing is performed on the scheduling information group after the CRC addition and the G-RNTI scrambling, and finally, the scheduling information group after the series of processing is placed in the search space. On the UE side, the UE does not know whether the base station sends scheduling information to itself, nor does it know the DCI type used by the scheduling information and the specific location of the DCI transmission. The UE only knows the DCI type and the possible location of the DCI transmission if the base station sends scheduling information to itself. These possible DCI types and possible locations sent by DCI constitute the search space. UE needs to be at Blind detection is performed in the search space, that is, PDCCH demodulation is performed for each possible DCI type and possible location, and the corresponding RNTI is used to descramble the CRC to obtain the correct DCI, thereby parsing the corresponding scheduling information. However, if the UE searches for the past in order, the amount of calculation on the UE side is considerable, especially for a system with a relatively large bandwidth. To this end, the concept of search space is defined, and some restrictions on the possible placement of PDCCHs in different formats in the system are made, which reduces the complexity of UE blind detection. Specifically, the Common Search Space, the UE-Specific Search Space, and the group-specific space of the cluster are divided, and correspondingly search for different scheduling information in different spaces. Among them, the type of blind detection capability of the UE is also different and can be divided into:

The blind detection capability of the Group Radio Network Temporary Identifier (G-RNTI) is a type 1 UE: supporting the temporary identification of the cell radio network in the PDCCH common space and the UE dedicated space in one downlink subframe ( C-RNTI, Cell Radio Network Temporary Identifier)/Semi-Persistent Scheduling (SPS), C-RNTI/Temporary C-RNTI blind detection, and supports G-in the PDCCH common search space and group private space. Terminal for blind detection of RNTI/SPS G-RNTI.

The blind detection capability of the G-RNTI is a Type 2 UE: supporting C-RNTI/SPS C-RNTI/Temporary C-RNTI blind detection in the PDCCH common space and the UE dedicated space in one downlink subframe, and simultaneously supporting A terminal in the PDCCH common search space but does not support G-RNTI/SPS G-RNTI blind detection in the group dedicated space.

However, for a UE whose blind detection capability is type 2, if the UE is already in the connected state and accesses the group call of the cluster, the blind check of the G-RNTI/SPS G-RNTI must be in the common search space. How to make the base station perceive such a scenario and to schedule the G-RNTI only in the common search space of the PDCCH is a problem that must be solved.

It should be noted that the apparatus in the embodiment of the present invention may include: a UE and a base station, and the following uses a base station and a UE as an example for description.

Embodiment 1

An embodiment of the present invention provides a method for processing scheduling information, as shown in FIG. 1 , which is a method for processing scheduling information implemented by a base station, and the method may include:

S101. When the base station detects that the UE is camped in the cell supporting the cluster, the base station sends a cluster paging message, where the cluster paging message is used to indicate that the UE performs cluster service.

It should be noted that the processing method of the scheduling information provided by the embodiment of the present invention is directed to the UE of the blind detection capability type 2 of the Group Radio Network Temporary Identifier (G-RNTI), and therefore, the present invention is implemented. The UE in the example supports C-RNTI (Cell Radio Network Temporary Identifier) in a common downlink (PDCCH, Physical Downlink Control Channel) common search space and a UE dedicated space in one downlink subframe. /Semi-Persistent Scheduling (SPS), C-RNTI/Temporary C-RNTI blind detection, and supports G-RNTI/SPS G-RNTI in the PDCCH common search space but not in the group-dedicated space. Blind UE.

It can be understood that the embodiment of the present invention is directed to a problem of processing scheduling information in a downlink transmission process.

In the embodiment of the present invention, the LTE-based trunking communication system needs to allocate a corresponding G-RNTI for the corresponding packet on the system in order to support the group call service (cluster service) of the broadband cluster. The UE can perform cluster services only when the cell supporting the cluster resides. The G-RNTI is a proprietary identifier in the LTE-based trunking communication system, and its function is the same as the RNTI in the LTE public network.

Specifically, when the base station and the UE perform the cluster service, the base station first sends the cluster paging message to the UE, so that the UE can configure the G-RNTI according to the cluster paging message, and start monitoring the service control channel of the cluster. (TCCH, Traffic Control Channel) monitors the listening user resource message sent by the base station.

Further, the base station sends a listening user resource message to the UE, so that the UE can configure the listening user resource according to the listening user resource message, and then enter the listening user to perform the cluster service.

S102. The base station detects the LTE service connection with the UE, and when receiving the control unit of the media access control layer (MAC) of the G-RNTI of the UE, the base station and the cluster service Corresponding scheduling information is set in a common search space to schedule the cluster service in the common search space.

When the UE is in the cell supporting the cluster, the base station sends a cluster paging message, and when the base station detects that the LTE service connection is established with the UE, the base station also performs LTE service with the UE. At this time, the base station receives the control unit of the MAC of the G-RNTI transmitted by the UE, and the base station sets the scheduling information corresponding to the cluster service in a common search space for scheduling. That is, when the physical layer of the base station side determines that the control unit of the MAC with the G-RNTI in the group call of the cluster is the RRC (Radio Resource Control) connection state of the type 2, the base station will cooperate with the cluster. The scheduling information corresponding to the service is set in a common search space of the PDCCH to schedule the cluster service in the common search space.

In particular, in the embodiment of the present invention, each cluster group (composed of UEs) in the LTE-based trunking communication system has corresponding scheduling information for each cluster group. Each cluster group belongs to a common group, and each public group corresponds to one scheduling information group. Therefore, each scheduling information group contains several scheduling information, and one scheduling information corresponds to one cluster group, that is, one scheduling information corresponds to one. G-RNTI.

The UE in the embodiment of the present invention is a UE in a cluster group.

It should be noted that, in the embodiment of the present invention, the sequence in which the base station sends the cluster paging message and detects the establishment of the LTE service connection connection is not limited, as long as the base station and the UE can perform the cluster service and the LTE service at this time. . In addition, in the embodiment of the present invention, when the base station and the UE are performing the trunking service and the LTE service, the base station may receive the control unit of the MAC of the G-RNTI of the UE.

It can be understood that when the base station acquires the control unit of the MAC of the G-RNTI of the UE, it is learned that the UE is supported in the PDCCH common search space in one downlink subframe, but is not supported in the group dedicated space. The UE performs the G-RNTI/SPS G-RNTI blind check. Therefore, the base station sets the scheduling information corresponding to the cluster service in the common search space for scheduling (it is originally scheduled in the group dedicated space). In this way, when the base station performs the scheduling information corresponding to the cluster service and the scheduling information corresponding to the LTE service in the common search space, the base station does not perform at the same time, thereby avoiding the occurrence of two types of service conflicts.

Further, after S101, as shown in FIG. 2, after the base station sends the cluster paging message, the method for processing the scheduling information provided by the embodiment of the present invention further includes: S103-S104. details as follows:

S103. The base station sets scheduling information corresponding to the cluster service in a common search space to schedule the cluster service in the common search space.

After the base station sends the cluster paging message, the base station may start a timer for the first paging of the group call performed by the base station, and the base station sets the scheduling information corresponding to the cluster service within a preset time set by the timer. In the public search space, the cluster service is scheduled in the common search space.

Optionally, the preset time may be 10 minutes, and the value of the specific preset time may be set by the designer according to the actual situation, which is not limited by the embodiment of the present invention.

It should be noted that the implementation of the preset time in the embodiment of the present invention is not limited to the implementation manner of the timer, and may also be an implementation manner capable of implementing the timing function.

S104. If the base station does not receive the control unit of the MAC of the G-RNTI of the UE, the base station sets the scheduling information corresponding to the cluster service in the common search space and the group dedicated space to The common search space and the group dedicated space schedule the cluster service.

After the preset time is set, the base station sets the scheduling information corresponding to the cluster service in the public search space for scheduling. If the base station does not receive the MAC address of the G-RNTI of the UE. The control unit sets the scheduling information corresponding to the cluster service in the common search space and the group dedicated space to schedule the cluster service in the common search space and the group dedicated space.

It can be understood that, when the base station determines that the cluster service is performed, the scheduling information corresponding to the cluster service may be set in a common search space for scheduling within a certain period of time, and then the G- of the UE is not received after the timer expires. When the control unit of the MAC of the RNTI indicates that the base station does not perform the cluster service and the LTE service at the same time, the two types of service conflicts do not occur. In this case, the base station sets the scheduling information corresponding to the cluster service in the common search space and The group dedicated space is performed to adapt the control unit of the MAC with the G-RNTI to perform scheduling of the service for the type 1 UE.

The embodiment of the present invention further provides a method for processing scheduling information, as shown in FIG. 3, which is a method for processing scheduling information implemented by a UE, where the method may include:

S201. When camping in a cell supporting the cluster, the UE determines the currently accessed data service.

It should be noted that the UE can perform the cluster service only when the cell supporting the cluster resides.

In the embodiment of the present invention, when the UE camps in the cell supporting the cluster, the UE determines which data services are currently accessed.

Specifically, when the UE establishes an RRC connection and an LTE service bearer with the base station, the UE determines that the currently accessed data service is an LTE service. The UE receives the cluster paging message sent by the base station, and determines that the currently accessed data service is a cluster service when the group paging message is added to the group call.

It should be noted that the sequence in which the UE determines whether it is an LTE service or a cluster service is not limited in the embodiment of the present invention.

Specifically, after the UE camps on the cell supporting the cluster, the UE can read the system information of the cluster. Block (SIB), and configure its own physical layer according to the resource content of the trunking paging channel (TPCH) in the cluster-specific SIB, and the physical layer can detect the cluster searching according to the cluster-specific TPCH resource parameters. Call the message. After the base station sends a cluster paging message, the base station can start a timer, and the scheduling information corresponding to the cluster service of the cluster group call is set in the common search space for scheduling before the timer expires. After receiving the cluster paging message, the UE is configured to listen to the TCCH resource of the user. After the configuration is complete, the UE monitors the trunk control channel (TCCH) channel, and the UE receives the configuration information of the cluster group, that is, the cluster service. TTCH (Trunking Traffic Channel) resource. In this way, the UE can listen to the user service resources according to the configuration of the received cluster listening user, and successfully enter the listening user to prepare for the cluster service. Then, the UE initiates an LTE service, that is, the UE initiates a connection request, and establishes an RRC connection and a service bearer in the same manner as the normal LTE service, and the connection is completed, and the LTE service is ready. Alternatively, after the UE camps on the cell supporting the cluster, the UE initiates the LTE service, initiates the establishment of the connection, and establishes the RRC connection and the service bearer in the same manner as the normal LTE service. After the connection is completed, the UE enters the RRC connection state and prepares for the LTE service. And the UE monitors the TPCH cluster paging channel. When the UE receives the cluster paging message, configures its own physical layer resource, monitors the cluster TCCH channel, and prepares the cluster service in response to the cluster paging message.

S202, when the currently accessed data service is an LTE service and a cluster service, the UE reports a control unit of the MAC of the G-RNTI, where the control unit of the MAC of the G-RNTI is the base station processes the LTE service and the The scheduling information corresponding to the cluster services is provided.

After the UE determines the currently accessed data service, when the currently accessed data service is the LTE service and the cluster service, the UE reports the control unit of the MAC of the G-RNTI, and the control unit of the MAC of the G-RNTI is processed by the base station. The scheduling information corresponding to the LTE service and the cluster service respectively provides a basis.

Specifically, the UE sends its own G-RNTI as a control unit of the MAC to the base station to inform the base station of the control unit of the MAC of its own G-RNTI. Among them, the control unit of the MAC The value of the uplink channel in the table is as shown in Table 1. The storage unit in the reservation in Table 1 is the control unit of the MAC of the G-RNTI. Therefore, the UE can use any value of Reserved with the base station side protocol. In this way, the base station can learn the control unit of the MAC of the G-RNTI of the corresponding UE from the value of Reserved. And the format of the control unit of the MAC in the embodiment of the present invention is as shown in FIG. 4.

Table 1

Specifically, after the UE camps on the cell supporting the cluster, the cluster-specific system information block (SIB) can be read, and the physical layer is configured according to the TPCH resource content in the cluster-specific SIB, and the physical layer is configured according to the cluster. The cluster paging message can be detected by the proprietary TPCH resource parameter. After the base station sends a cluster paging message, the base station can start a timer, and the scheduling information corresponding to the cluster service of the cluster group call is set in the common search space for scheduling before the timer expires. After receiving the cluster paging message, the UE configures the TCCH resource of the user, and after monitoring the TCCH channel, the UE receives the configuration information of the cluster group, that is, the TTCH resource. In this way, the UE can listen to the user service resources according to the configuration of the received cluster listening user, and successfully enter the listening user to prepare for the cluster service. Then, the UE initiates an LTE service, that is, the UE initiates a connection request, and establishes an RRC connection and a service bearer in the same manner as the normal LTE service, and the connection is completed, and the LTE service is prepared, and the UE queries the user resource through the RRC query. If yes, the UE is notified that the UE has been connected to the cluster, and then the UE notifies the sending of the message of the control unit carrying the MAC to the base station. Thereafter, if the timer expires, the base station determines that the timer expires, and the UE reports the G-RNTI. The control unit of the MAC, the base station keeps the scheduling information corresponding to the cluster service scheduled in the common search space. Or, after the UE camps on the cell supporting the cluster, the UE initiates the LTE service, initiates the establishment of the connection, and establishes an RRC connection and a service bearer in the same manner as the normal LTE service. After the connection is completed, the UE enters the RRC connection state and prepares for LTE. The service, and the UE monitors the TPCH cluster paging channel. When the UE receives the cluster paging message, configures its own physical layer resource, monitors the cluster TCCH channel, and prepares the cluster service in response to the cluster paging message. The UE determines that the current RRC connection state is sent, and sends a message of the control unit that carries the MAC to the base station. After receiving the message, the base station determines that the control unit of the MAC that is the G-RNTI is the type 2 called UE, and is In the RRC connection state, the base station schedules the scheduling information corresponding to the cluster service of the cluster group call in the PDCCH common space.

The method for processing the scheduling information provided by the embodiment of the present invention, when the UE camps in the cell supporting the cluster, sends a cluster paging message, where the cluster paging message is used to indicate that the cluster service is performed with the UE; When the LTE service connection is established, and the control unit of the MAC of the G-RNTI of the UE is received, the scheduling information corresponding to the cluster service is set in the common search space to schedule the cluster service in the common search space. With the foregoing implementation, the UE sends the control unit of the MAC of the G-RNTI of the UE to the base station when the LTE service and the cluster service exist simultaneously, so that the base station can determine the cluster according to the control unit of the MAC of the G-RNTI of the UE. The scheduling information corresponding to the service is placed in the common search space to schedule the cluster service in the common search space. Then, the base station can transmit scheduling information to the UE by using a corresponding modulation manner, and the base station knows that the cluster service is performed in the public search space. And LTE business, therefore, based The station does not send the scheduling information corresponding to the cluster service and the LTE service at the same time, thereby avoiding the conflict problem occurring when the LTE service and the cluster service are simultaneously scheduled.

Embodiment 2

An embodiment of the present invention provides a method for processing scheduling information. As shown in FIG. 5, the method may include:

S301. The UE sends a cluster paging message to the UE in the cell supporting the cluster, where the cluster paging message is used to indicate that the UE performs cluster service.

It should be noted that the processing method of the scheduling information provided by the embodiment of the present invention is directed to the UE of the blind detection capability type 2 of the G-RNTI. Therefore, the UE in the embodiment of the present invention supports the PDCCH in one downlink subframe. C-RNTI/SPS C-RNTI/Temporary C-RNTI blind detection in the common search space and the UE-dedicated space, and supports G-RNTI/SPS G in the PDCCH common search space but not in the group-dedicated space. - RNTI blinded UE.

Specifically, when the base station and the UE perform the cluster service, the base station first sends a cluster paging message to the UE, so that the UE can configure the G-RNTI according to the cluster paging message, and start monitoring the cluster. The TCCH monitors the listening user resource message sent by the base station.

As an implementation manner, the base station sends a listening user resource message to the UE, so that the UE can configure the listening user resource according to the listening user resource message, and then enter the listening user to perform the clustering industry. Business.

The cluster paging message can be detected by the proprietary TPCH resource parameter. After the base station sends a cluster paging message, the base station can start a timer, and the scheduling information corresponding to the cluster service of the cluster group call is set in the common search space for scheduling before the timer expires. After receiving the cluster paging message, the UE configures the TCCH resource of the user, and after monitoring the TCCH channel, the UE receives the configuration information of the cluster group, that is, the TTCH resource. In this way, the UE can listen to the user service resources according to the configuration of the received cluster listening user, and successfully enter the listening user to prepare for the cluster service. Then, the UE initiates the LTE service, that is, the UE initiates the connection establishment request, and establishes the RRC connection and the service bearer in the same manner as the normal LTE service, and the connection is completed, and the LTE service is ready. Alternatively, after the UE camps on the cell supporting the cluster, the UE initiates the LTE service, initiates the establishment of the connection, and establishes the RRC connection and the service bearer in the same manner as the normal LTE service. After the connection is completed, the UE enters the RRC connection state and prepares for the LTE service. And the UE monitors the TPCH cluster paging channel, and when the UE receives the cluster paging message, configures its own physical layer resource, monitors the cluster TCCH channel, and prepares the cluster service in response to the cluster paging message.

S303, when the currently accessed data service is an LTE service and a cluster service, the UE reports a control unit of the MAC of the G-RNTI, where the control unit of the MAC of the G-RNTI processes the LTE service and the cluster service The corresponding scheduling information is provided separately.

Specifically, the UE sends its own G-RNTI as a control unit of the MAC to the base station to inform the base station of the control unit of the MAC of its own G-RNTI. The value of the uplink channel in the control unit of the MAC is as shown in Table 1. The storage unit in the reservation in Table 1 is the control unit of the MAC of the G-RNTI. Therefore, the UE can use any of the Reserved protocols in the protocol with the base station. value. In this way, the base station can learn the control unit of the MAC of the G-RNTI of the corresponding UE from the value of Reserved. And the format of the control unit of the MAC in the embodiment of the present invention is as shown in FIG. 4.

Table 1

S304: When the base station detects that the LTE service connection is established with the UE, the base station sets scheduling information corresponding to the cluster service in a common search space, to the set in the common search space. Group services are scheduled.

After the UE reports the control unit of the MAC of the G-RNTI, the base station also detects that the LTE service connection is established with the UE, that is, the eNB indicates that the base station will also perform LTE service with the UE, if the base station receives the UE to send at this time. The control unit of the MAC of the G-RNTI of the UE, the base station sets scheduling information corresponding to the cluster service in a common search space for scheduling. That is, when the physical layer of the base station side determines that the blind detection capability of the G-RNTI in the group call of the cluster is the RRC connected state of the type 2, the base station sets the scheduling information corresponding to the cluster service in the public PDCCH. Searching for space to schedule the clustered traffic in the common search space.

In particular, in the embodiment of the present invention, each cluster group (composed of UEs) in the LTE-based trunking communication system has corresponding scheduling information for each cluster group. Since each cluster group belongs to a public group, each public group corresponds to one scheduling information group, so each scheduling information group contains several scheduling information, and one scheduling information corresponds to one cluster group, that is, one scheduling information. Corresponds to a G-RNTI.

The UE in the embodiment of the present invention is a UE in a cluster group.

It should be noted that, in the embodiment of the present invention, the sequence in which the base station sends the cluster paging message and detects the establishment of the LTE service connection connection is not limited, as long as the base station and the UE can perform the cluster service and the LTE service at this time. . In addition, in the embodiment of the present invention, when the base station and the UE are performing the cluster service and the LTE service at this time, the base station may receive the control unit that the UE sends the MAC of the G-RNTI of the UE.

It can be understood that when the base station acquires the control unit of the MAC of the G-RNTI of the UE, it is learned that the UE is supported in the PDCCH common search space in one downlink subframe, but is not supported in the group dedicated space. The UE performs the G-RNTI/SPS G-RNTI blind check. Therefore, the base station sets the scheduling information corresponding to the cluster service in the common search space for scheduling (it is originally scheduled in the group dedicated space). In this way, when the base station performs the scheduling information corresponding to the cluster service in the common search space and the scheduling information corresponding to the LTE service, it is not at the same time. In progress, thus avoiding the occurrence of two kinds of business conflicts.

S305. The base station sets, in a preset time, scheduling information corresponding to the cluster service in a common search space, to schedule the cluster service in the common search space.

After the base station sends the cluster paging message, the base station may start a timer for the first paging of the group call performed by the base station, and the base station will perform scheduling information corresponding to the cluster service within a preset time set by the timer. Set in the common search space to schedule the cluster service in the common search space.

As an embodiment, the preset time may be 10 minutes, and the value of the specific preset time may be set by the designer according to the actual situation, which is not limited by the embodiment of the present invention.

S306, when the base station does not receive the control unit of the MAC of the G-RNTI of the UE, the base station sets the scheduling information corresponding to the cluster service in the common search space and the group dedicated space, in the The public search space and the common search space schedule the cluster service.

After the base station sets the scheduling information corresponding to the cluster service in the public search space for scheduling, if the base station does not receive the control unit of the G-RNTI of the UE, the base station does not receive the control unit of the G-RNTI of the UE. The scheduling information corresponding to the cluster service is set in a common search space and a group dedicated space to schedule the cluster service in the common search space and the common search space.

It can be understood that, when the base station determines that the cluster service is performed, the scheduling information corresponding to the cluster service may be set in a common search space for scheduling within a certain period of time, and then the G- of the UE is not received after the timer expires. When the control unit of the MAC of the RNTI indicates that the base station does not perform the cluster service and the LTE service at the same time, the two types of service conflicts do not occur. In this case, the base station sets the scheduling information corresponding to the cluster service in the common search space and Group specific The space is performed to adapt the control unit of the MAC with the G-RNTI to perform scheduling of the service for the type 1 UE.

Specifically, after the UE camps on the cell supporting the cluster, the cluster-specific system information block (SIB) can be read, and the physical layer is configured according to the TPCH resource content in the cluster-specific SIB, and the physical layer is configured according to the cluster. The cluster paging message can be detected by the proprietary TPCH resource parameter. After the base station sends a cluster paging message, the base station can start a timer, and the scheduling information corresponding to the cluster service of the cluster group call is set in the common search space for scheduling before the timer expires. After receiving the cluster paging message, the UE configures the TCCH resource of the user, and after monitoring the TCCH channel, the UE receives the configuration information of the cluster group, that is, the TTCH resource. In this way, the UE can listen to the user service resources according to the configuration of the received cluster listening user, and successfully enter the listening user to prepare for the cluster service. Then, the UE initiates an LTE service, that is, the UE initiates a connection request, and establishes an RRC connection and a service bearer in the same manner as the normal LTE service, and the connection is completed, and the LTE service is prepared, and the UE queries the user resource through the RRC query. If yes, the UE is notified to the group call of the cluster, and then the UE notifies the sending of the message of the control unit carrying the MAC to the base station. Thereafter, if the timer expires, the base station determines that the timer expires, and the UE reports the G-RNTI. The control unit of the MAC, the base station keeps scheduling information corresponding to the cluster service scheduled in the common search space. Or, after the UE camps on the cell supporting the cluster, the UE initiates the LTE service, initiates the establishment of the connection, and establishes an RRC connection and a service bearer in the same manner as the normal LTE service. After the connection is completed, the UE enters the RRC connection state and prepares for LTE. The service, and the UE monitors the TPCH cluster paging channel. When the UE receives the cluster paging message, configures its own physical layer resource, monitors the cluster TCCH channel, and prepares the cluster service in response to the cluster paging message. If the UE determines that it is currently in the RRC connected state, it sends a message carrying the control unit of the MAC to the base station, and after receiving the message, the base station determines that the control unit of the MAC that is the G-RNTI is the type 2 called UE, and For the RRC connection state, the base station schedules the scheduling information corresponding to the cluster service of the cluster group call in the PDCCH common space.

It should be noted that step S302-step S304 and step S305-step S306 in the embodiment of the present invention are optional steps after step S301, and one of the steps is selected according to the actual detection situation; that is, in the embodiment of the present invention. After step S301, step S302-step S304 may be performed, and step S305-step S306 may be performed. The specific execution order may be determined according to an actual situation, and is not limited in the embodiment of the present invention; and, step S302-step S304 or step After the execution of S305-step S306, the processing flow ends.

The method for processing the scheduling information provided by the embodiment of the present invention, when the UE is camped in the cell supporting the cluster, the cluster paging message is sent, where the cluster paging message is used to indicate the cluster service with the UE; When the LTE service connection is established with the UE, and the control unit of the MAC of the G-RNTI of the UE is received, the scheduling information corresponding to the cluster service is set in the common search space to access the cluster service in the common search space. Schedule. With the foregoing implementation, the UE sends the control unit of the MAC of the G-RNTI of the UE to the base station when the LTE service and the cluster service exist simultaneously, so that the base station can determine the cluster according to the control unit of the MAC of the G-RNTI of the UE. The scheduling information corresponding to the service is placed in a common search space to schedule the cluster service in the common search space, so that the base station can transmit scheduling information to the UE by using a corresponding modulation manner, and the base station knows that the public search space is performed. The cluster service and the LTE service, therefore, the base station does not transmit the scheduling information corresponding to the cluster service and the LTE service at the same time, thereby avoiding the conflict problem when the LTE service and the cluster service are simultaneously scheduled.
