Technical field

This application relates to the field of communications, and more specifically, to a method and device for parameter reconfiguration.

Background technique

With the rapid development of wireless communication and the rapid growth of market demand, the communication between people has long been unable to meet the demand. Therefore, the Internet of Things (IoT) technology came into being. For example, machine-to-machine communication (machine to machine, M2M) is to transfer information and data to each other through a wireless network, which is an important direction of IoT development. Among them, M2M devices are mostly relatively small battery-powered systems, such as smart meter reading systems, which need to periodically detect and report on the usage of water, electric gas, etc. The services transmitted between M2M devices may be machine type communication (MTC) services. The MTC services have some special service characteristics, such as small transmission data volume, obvious service periodicity, low power consumption and terminal data volume Great.

In short, there is a high requirement for the drop rate between devices using IoT technology, and the reliability of signal transmission between devices needs to be solved urgently.

Summary of the invention

The present application provides a method and device for parameter reconfiguration, which can improve the reliability of signal transmission.

In a first aspect, a method of parameter reconfiguration is provided. The method includes: a terminal receives a radio resource control RRC connection reconfiguration message using a first parameter, and the RRC connection reconfiguration message is used to indicate a second parameter; the terminal uses the The first parameter sends an RRC connection reconfiguration complete message, and the RRC connection reconfiguration complete message is used to instruct the terminal to receive the RRC connection reconfiguration message using the first parameter; after sending the RRC connection reconfiguration complete message, the terminal Use the second parameter to communicate with the network device.

The terminal uses the first parameter to receive the RRC connection reconfiguration message indicating the second parameter, and performs the reconfiguration of the second parameter, and uses the first parameter to send the RRC connection to the network device after the reconfiguration of the second parameter is completed Reconfiguration complete message, after sending the RRC connection reconfiguration complete message, the second parameter is used to communicate with the network device, so that the terminal does not successfully receive the RRC connection reconfiguration message, and still uses the first parameter to communicate with the network device Communication, and after the network device sends the RRC connection reconfiguration complete message, it uses the second parameter to communicate with the terminal, resulting in a problem of inconsistent use parameters of the transceiver. That is to say, after sending the RRC connection complete message through the first parameter in the embodiment of the present application, the terminal communicates with the network device through the second parameter, which reduces the call drop rate in the communication between the terminal and the network device.

In some possible implementation manners, the method further includes: the terminal starts a timer when sending the RRC connection reconfiguration complete message; wherein, after sending the RRC connection reconfiguration complete message, the terminal uses the second The communication between the parameter and the network device includes: when the timer expires, the terminal uses the second parameter to communicate with the network device.

The terminal starts the timer on the terminal side when sending the RRC connection reconfiguration complete message. It can be understood that the terminal starts the timer after delivering the RRC connection reconfiguration complete message to the bottom layer, and expires when the timer expires, that is, from the time out Or the second parameter is used for communication from the overflow time, that is, the terminal and the network device use the same second parameter for communication, which reduces the call drop rate between the network device and the terminal and improves the reliability of the configuration parameter.

In some possible implementation manners, the setting duration of the timer is the period for transmitting the physical uplink shared channel PUSCH or the period for transmitting the physical downlink shared channel PDSCH or the physical downlink control channel PDCCH between the terminal and the network device The period is the unit.

The setting duration of the timer may be a unit of a PUSCH cycle, a PDSCH cycle or a PDCCH cycle, that is, the embodiments of the present application may be applied to different scenarios, which improves the flexibility of application.

In some possible implementations, in the case where data transmission is scheduled through the PDCCH, the setting duration of the timer is the unit of the period for transmitting the PDCCH between the terminal and the network device; when the data passes the pre-configured resources In the case of transmission, the setting duration of the timer is the unit of the period for transmitting the PUSCH and / or the PDSCH between the terminal and the network device.

In some possible implementations, the RRC connection reconfiguration message carries the set duration of the timer.

By carrying the setting duration of the timer in the RRC connection reconfiguration message, the network device is prevented from sending special signaling to configure the setting duration of the timer, and signaling overhead is reduced.

In some possible implementations, the terminal may start a timer when it receives the RRC connection reconfiguration message using the first parameter, and before the timer expires, if the terminal fails to send the RRC connection reconfiguration complete message, it may also use The first parameter retransmits the RRC connection reconfiguration complete message.

The terminal starts a timer when it receives the RRC connection reconfiguration message using the first parameter. If the terminal does not successfully complete the reconfiguration of the RRC connection reconfiguration message according to the RRC connection reconfiguration message received in step 401, the terminal will not report to the network The device feeds back an RRC connection complete message. Correspondingly, if the network device does not receive the RRC connection reconfiguration complete message within the preset time period, it can re-send the RRC connection complete message to the terminal, so that the terminal can re-receive the RRC connection reconfiguration message using the first parameter until the parameter is completed Reconfiguration sends an RRC connection reconfiguration complete message to the network device, thereby increasing the probability of successful transmission of the RRC connection reconfiguration message, and further reducing the call drop rate in the communication between the network device and the terminal.

In the embodiment of the present application, the IOT technology can achieve a mass connection, deep coverage, and terminal power saving through, for example, narrowband NB technology. For example, NB includes only one resource block (resource block, RB), that is, the bandwidth of NB is only 180KB. To achieve massive access, the terminal must be discrete in access. According to the method of the embodiment of the present application, the congestion problem of the IOT technology massive terminal when accessing the network through the NB can be effectively solved.

FIG. 1 is a schematic diagram of a communication system of the present application. The communication system in FIG. 1 may include at least one terminal (eg, terminal 10, terminal 20, terminal 30, terminal 40, terminal 50, and terminal 60) and network device 70. The network device 70 is used to provide a communication service for the terminal and access the core network. The terminal can access the network by searching for synchronization signals, broadcast signals, etc. sent by the network device 70 to communicate with the network. The terminal 10, the terminal 20, the terminal 30, the terminal 40, and the terminal 60 in FIG. 1 may perform uplink and downlink transmission with the network device 70. For example, the network device 70 may send downlink signals to the terminal 10, terminal 20, terminal 30, terminal 40, and terminal 60, or may receive uplink signals sent by the terminal 10, terminal 20, terminal 30, terminal 40, and terminal 60.

In addition, the terminal 40, the terminal 50, and the terminal 60 can also be regarded as a communication system. The terminal 60 can send a downlink signal to the terminal 40 and the terminal 50, and can also receive an uplink signal sent by the terminal 40 and the terminal 50.

FIG. 2 shows a schematic flowchart of a signal transmission method in a conventional solution.

201, the terminal sends (message, MSG) 1 to the network device, that is, initiates random access;

202. The network device sends the response message of the MSG1 to the terminal, that is, message (MSG) 2, and the MSG2 includes a timing advance (TA) and uplink resources;

203. The terminal sends a radio resource control (radio resource control (RRC) connection establishment request (connection request) to the network device on the uplink resource according to the TA;

204, the network device sends a conflict resolution message (or RRC connection establishment message) to the terminal, where the conflict resolution message is used to indicate random access success;

205, the terminal sends an RRC connection establishment complete message to the network device after winning the conflict;

206. After receiving the RRC connection establishment complete message, the network device sends an RRC connection reconfiguration message to the terminal, and the network device immediately takes effect of the new configuration parameters indicated in the RRC connection reconfiguration message after sending the RRC connection reconfiguration message;

207. After receiving the RRC connection reconfiguration message, the terminal immediately takes effect of the new configuration parameters indicated in the RRC connection reconfiguration message;

208. The terminal sends the RRC connection reconfiguration complete message using the new configuration parameters.

In the traditional solution, the network device takes effect of the new configuration parameter immediately after sending step 206. However, due to the physical downlink shared channel (PDSCH) carrying the RRC connection reconfiguration message, there will be a certain bit error rate or block error rate during transmission, that is, the terminal may not receive the RRC connection reconfiguration message ,As shown in Figure 3. In this way, the network device has used the new configuration parameters to communicate with the terminal, and the terminal is still using the original configuration parameters for communication. Due to the inconsistency of the configuration parameters, the communication between the network device and the terminal is dropped.

FIG. 4 shows a schematic flowchart of a parameter reconfiguration method in an embodiment of the present application.

401. The terminal receives the RRC connection reconfiguration message using the first parameter, and the RRC connection reconfiguration message is used to indicate the second parameter. Correspondingly, the network device uses the first parameter to send the RRC connection reconfiguration message.

Specifically, before step 205 shown in FIG. 2, the terminal uses the first parameter to communicate with the network device. In the embodiment of the present application, the terminal receives the RRC connection reconfiguration message using the first parameter, and the RRC connection reconfiguration message is used to indicate a new configuration parameter (that is, the second parameter), that is, the network device uses the RRC connection reconfiguration message as the terminal Configure the second parameter.

It should be understood that using the first parameter to receive the RRC connection reconfiguration message means receiving the RRC connection reconfiguration message using the configuration before the RRC connection reconfiguration, and the second parameter is the new configuration parameter in the RRC connection reconfiguration message.

It should be understood that the above parameters may include time-frequency code resources, and may also include port numbers, etc., which is not limited in this application. That is, the first parameter and the second parameter may be that at least one of the included time-frequency resource and the port number is different.

The first parameter and the second parameter may also be downlink transmission mode configuration, uplink transmission mode configuration, downlink resource configuration (such as physical downlink control channel (physical downlink control channel, PDCCH), physical downlink shared channel (physical downlink shared channel, PDSCH) Configuration), transmission repetition number configuration, resource location configuration, PDCCH specific configuration, uplink no scheduling configuration, downlink no scheduling configuration (such as PDSCH transmission carrier configuration, transmission interval, repetition number configuration); multi-hybrid automatic retransmission request (hybrid automatic retransmission request request, HARQ) configuration, 2HARQ process configuration, 4HARQ process configuration, security configuration, frame structure configuration, etc.

Optionally, the terminal performs parameter reconfiguration for the terminal according to the second parameter indicated in the RRC connection reconfiguration message.

402. After completing the reconfiguration parameter, the terminal uses the first parameter to send an RRC connection reconfiguration completion message. Correspondingly, the network device uses the first parameter to receive the RRC connection reconfiguration complete message.

Specifically, the terminal sends an RRC connection reconfiguration completion message to the network device, that is, the RRC connection reconfiguration completion message indicates that the terminal has received the second parameter.

In one embodiment, the terminal may start a timer when receiving the RRC connection reconfiguration message using the first parameter. Before the timer expires, if the terminal fails to send the RRC connection reconfiguration complete message, the terminal may also use the first A parameter retransmits the RRC connection reconfiguration complete message.

Specifically, the terminal starts a timer when receiving the RRC connection reconfiguration message using the first parameter. If the terminal does not successfully complete the reconfiguration of the RRC connection reconfiguration message according to the RRC connection reconfiguration message received in step 401, the terminal does not The RRC connection completion message will be fed back to the network device. Correspondingly, if the network device does not receive the RRC connection reconfiguration complete message within the preset time period, it can re-send the RRC connection complete message to the terminal, so that the terminal can re-receive the RRC connection reconfiguration message using the first parameter until the parameter is completed Reconfiguration sends an RRC connection reconfiguration complete message to the network device, thereby increasing the probability of successful transmission of the RRC connection reconfiguration message, and further reducing the call drop rate in the communication between the network device and the terminal.

It should be understood that during the timing of the timer, the network device may retransmit the RRC connection reconfiguration message may be retransmitted once or multiple times, which is not limited in this application.

Optionally, after the timer expires, the terminal uses the second parameter to communicate with the network device.

Optionally, the network device starts a timer on the network device side when receiving the RRC connection reconfiguration complete message, and uses the second parameter to communicate with the terminal after the timer expires.

In another embodiment, the terminal starts a timer when sending an RRC connection reconfiguration complete message. Correspondingly, when receiving the RRC connection reconfiguration complete message, the network device also starts a timer.

Specifically, the terminal starts the timer on the terminal side when sending the RRC connection reconfiguration complete message. It can be understood that the terminal starts the timer after delivering the RRC connection reconfiguration complete message to the bottom layer, and the network device receives the RRC connection reconfiguration complete message Start the timer on the network device side, and when the timer expires, that is, from the time of timeout, or from the time of overflow, the second parameter is used for communication, that is, the terminal and the network device use the same second parameter for communication, reducing The call drop rate of communication between the network equipment and the terminal is improved, and the reliability of configuration parameters is improved.

It should be understood that the specific start timer starts at layer 3, whether layer 2 starts or layer 1 starts depends on the UE implementation.

It should also be understood that the timer set on the terminal side and the timer on the network device side may have the same duration, that is, the duration of the terminal sending the RRC connection reconfiguration complete message is ignored. Or detect in advance the duration of the RRC connection reconfiguration completion message between the terminal and the network device, and then set the timer on the terminal side to be longer than the timer on the network device side by the pre-measured duration, that is, to further make the terminal side and The network device side can simultaneously communicate using the second parameter.

Optionally, the duration of the timer set in the embodiment of the present application may be a unit of a period for sending and receiving signaling or data between the terminal and the network device.

Specifically, the period of signaling sent and received between the terminal and the network device may be the period of the PDCCH carrying signaling in the scheduling scenario, or the physical uplink shared channel (PUSCH) carrying signaling in the non-scheduling scenario. Or PDSCH period.

The period of data sent and received between the terminal and the network device may be the period of PUSCH or PDSCH carrying data.

For example, the duration of the timer may be set to 5 or 8 transmission cycles (PUSCH or PDSCH cycle or PDCCH scheduling cycle).

Optionally, the setting duration of the timer can be configured through the RRC connection reconfiguration message. The name of the timer can be T120, which is not limited here.

Specifically, for a scheduled transmission scenario, the setting time of the timer may be in units of the PDCCH transmission period, and for a non-scheduled transmission scenario, the setting time of the timer may be in the unit of PUSCH transmission period or PDSCH transmission period. Scheduling transmission indicates that data is transmitted through the resources scheduled by the PDCCH (uplink data transmission or downlink data transmission). The non-scheduling scenario is that the network device pre-configures resources for the terminal, and the terminal and the network device directly perform PDSCH and / or PUSCH transmission on the pre-configured resources. Unscheduled transmission does not rely on PDCCH scheduling. The resources pre-configured in the network are resources configured through an RRC message or other media intervention control layer control unit (media access control element (MAC)).

It should be noted that the transmission period of the data or signaling may be pre-configured by the network device, may also be agreed by the protocol, or a default fixed value of the network device and the terminal, such as a default of 5 transmission periods. This application does not limit this.

403. After sending the RRC connection reconfiguration complete message, the terminal uses the second parameter to communicate with the network device. Correspondingly, the network device uses the second parameter to communicate with the terminal.

Specifically, the communication between the network device and the terminal may specifically send signaling and / or data, or receive signaling and / or data. The terminal uses the first parameter to receive the RRC connection reconfiguration message indicating the second parameter, and performs the reconfiguration of the second parameter, and uses the first parameter to send the RRC connection to the network device after the reconfiguration of the second parameter is completed Reconfiguration complete message, after sending the RRC connection reconfiguration complete message, the second parameter is used to communicate with the network device, so that the terminal does not successfully receive the RRC connection reconfiguration message, and still uses the first parameter to communicate with the network device Communication, and the network device uses the second parameter to send the RRC connection reconfiguration message and then uses the second parameter to cause the problem of inconsistent use parameters at the transceiver end. It is determined that the terminal receives the RRC connection reconfiguration message, and then the network device and the terminal communicate via the second parameter, thereby reducing the call drop rate of communication between the terminal and the network device.

It should be noted that, in the embodiment of the present application, starting the corresponding operation after sending a message may start the operation immediately after sending the message, or may start the operation after a preset time period after sending the message expires operating. For example, the terminal uses the newly effective second parameter immediately after sending the RRC connection reconfiguration complete message, or may use the newly effective second parameter after a preset time period, which is not limited in this application.

Optionally, after sending the RRC connection reconfiguration completion message, the terminal may also receive an RRC connection reconfiguration completion confirmation message sent by the network device. After receiving the RRC connection reconfiguration completion confirmation message, the terminal may adopt the second parameter Communicate with network equipment.

Specifically, after sending the RRC connection reconfiguration completion message, the terminal may wait for receiving the RRC connection reconfiguration completion confirmation message sent by the network device, and after receiving the RRC connection reconfiguration completion confirmation message, start using the second parameter and Network devices communicate. Correspondingly, after receiving the RRC connection reconfiguration completion message, the network device sends an RRC connection reconfiguration completion confirmation message to the terminal device, and after sending the RRC connection reconfiguration completion confirmation message, starts to communicate with the terminal using the second parameter. This ensures that the network device has determined that the terminal receives the RRC connection reconfiguration message indicating the second parameter, and the terminal also determines that the network device has received the RRC connection reconfiguration complete message, thereby enabling the terminal and the network device to adopt the consistent second parameter Carrying out communication further reduces the call drop rate between the terminal and the network device.

It should be noted that the steps 401 and 402 performed by the network device may be performed by the L3 layer or L2 of the network device, and the confirmation message sent by the network device to complete the RRC connection reconfiguration may also be performed by L3 of the network device.

Optionally, after receiving the RRC connection reconfiguration completion confirmation message, the terminal may also send a feedback message of the RRC connection reconfiguration completion confirmation message to the network device, where the feedback message is used to indicate whether the terminal receives the RRC connection reconfiguration completion message Confirm the message.

Specifically, the feedback message may include an acknowledgement message (acknowledgement, ACK) and a negative acknowledgement message (negativeacknowledgement, NACK). After the terminal receives the RRC connection reconfiguration completion confirmation message, the feedback message is ACK, and is not received. After the RRC connection reconfiguration completion confirmation message, the feedback message is NACK. The network device uses the second parameter to communicate with the terminal when receiving the feedback message as ACK. The network device uses the first parameter to communicate with the terminal when receiving the feedback message as NACK. In addition, the message length of the feedback message of the RRC connection reconfiguration completion confirmation message is relatively small, the overhead of transmitting the feedback message is small, and the overhead of the network device identifying the feedback message is also small, that is, communication overhead is saved.

It should be noted that the L2 layer of the network device can receive the feedback message, and the L2 layer executes the effective second parameter.

Optionally, after receiving the RRC connection reconfiguration complete message, the network device may also send indication information, which is used to indicate the starting moment of using the second parameter to communicate with the terminal, and the terminal receives the indication information After that, the second parameter is used to communicate with the network device from the starting time indicated by the instruction information, and accordingly, the network device also uses the second parameter to communicate with the terminal from the starting time indicated by the instruction information.

Specifically, before the start time, the network device and the terminal communicate with the network device using the first parameter, and the second parameter can be used for communication from the time indicated by the indication information as the start time, that is, among the devices at both ends of the communication The two parameters take effect at the same time point, which further ensures the reliability of the communication and reduces the call drop rate.

Optionally, the starting time may be an absolute time point, or a relative time interval from the sending and receiving time.

It should be noted that the network device sends the indication information to the terminal, which may be that the L3 layer of the network device can provide the terminal to the L2 layer on the L2 layer, and the second parameter is activated by the L2 layer of the terminal.

Optionally, the starting time may be a time domain resource number.

Specifically, the time domain resource may be at least one of a frame, a radio frame, a subframe, a time slot, a mini-slot, or orthogonal frequency division multiplexing (OFDM) symbol. Accordingly, the time domain resource number is the corresponding number of the corresponding time domain resource. For example, it can be a subframe number.

Optionally, the indication information may be carried in a media access control layer control unit (media access control element (MAC) CE), which prevents the network device from specifically sending the indication information and reduces signaling overhead.

Therefore, in the method of parameter reconfiguration according to the embodiment of the present application, the terminal uses the first parameter to receive the RRC connection reconfiguration message indicating the second parameter, and performs the reconfiguration of the second parameter, after completing the reconfiguration of the second parameter After the configuration, the first parameter is used to send an RRC connection reconfiguration complete message to the network device, and the second parameter is used to communicate with the network device after the RRC connection reconfiguration complete message is sent, which prevents the terminal from successfully receiving the RRC connection The reconfiguration message still uses the first parameter to communicate with the network device, and after the network device sends the RRC connection reconfiguration complete message, it uses the second parameter to communicate with the terminal, resulting in inconsistent use parameters of the transceiver, that is, this application Embodiment The network device determines that the terminal receives the RRC connection reconfiguration message through the received RRC connection reconfiguration complete message, and then the network device and the terminal communicate through the second parameter, thereby reducing the call drop between the terminal and the network device rate.

FIG. 5 shows a schematic flowchart of a parameter reconfiguration method according to another embodiment of the present application.

It should be noted that, unless otherwise specified, the same terms in the embodiments of the present application and the foregoing embodiments have the same meaning.

501. The terminal determines that the feedback message is a confirmation response message or a negative response message according to whether the RRC connection reconfiguration message is received using the first parameter. The RRC connection reconfiguration message is used to indicate the second parameter.

Specifically, if the terminal receives the RRC connection reconfiguration message, the feedback message is a confirmation response message. If the terminal does not receive the RRC connection reconfiguration message, the feedback message is a negative response message.

Optionally, when the feedback message is a negative response message, the terminal uses the first parameter for communication and uses the first parameter to re-receive the RRC connection reconfiguration message. Correspondingly, when the feedback message is a negative response message, the network device uses the first parameter for communication and repeatedly sends the RRC connection reconfiguration message.

502. The terminal sends the feedback message using the first parameter. Correspondingly, the network device receives the feedback message.

503. The terminal uses the second parameter to communicate with the network device when the feedback message is a confirmation response message.
