Communication method and equipment

Technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a communication method and device.

Background technique

5G New Radio (NR) supports uplink grant free, that is, pre-configure some resources for terminal use. Therefore, after the terminal establishes a connection with the base station, when the terminal does not receive the uplink scheduling of the base station, it can directly send uplink data to the base station through pre-configured resources, which can reduce the transmission delay of the uplink data. However, when the base station pre-configures the same resource to multiple terminals, although the base station can distinguish uplink data from different terminals by using demodulation reference signals (DMRS) of different terminals, multiple terminals use pre-configuration The time of the resources will conflict, which will affect the performance of the base station receiving signals, increase the number of retransmissions of uplink data, and reduce the communication efficiency.

It can be seen that after receiving the instruction information for retransmitting uplink data, a dedicated resource can be requested from the network device, so that the uplink data and / or newly transmitted uplink data can be retransmitted through the dedicated resource, which can prevent multiple communication devices from using the same data. One shared resource reduces the number of retransmissions of uplink data, which can improve communication efficiency. Among them, the shared resource is a pre-configured resource (Configured grant), which is a resource that is pre-configured by the network device for the communication device, and one resource may be configured to one or more communication devices. A proprietary resource is a resource dynamically allocated by a network device for a communication device, and a resource can only be configured for use by one communication device.

When the number of consecutive transmissions counted by the counter is greater than a threshold, the uplink is sent to the communication device. The resource information can avoid assigning exclusive resources to the communication device as soon as there is instruction information for retransmitting uplink data, thereby avoiding wasting resources.

detailed description

Embodiments of the present invention disclose a communication method and device, which are used to improve communication efficiency. Each of them will be described in detail below.

In order to better understand a communication method and device disclosed in the embodiments of the present invention, the network architecture used in the embodiments of the present invention is described below first. Please refer to FIG. 1, which is a schematic diagram of a network architecture disclosed by an embodiment of the present invention. As shown in FIG. 1, the network architecture may include a terminal 1 and a base station 2, and the terminal 1 and the base station 2 are connected through a wireless network. The terminal 1 is configured to send uplink control signaling to the base station 2 through a physical uplink control channel (PUCCH), and send uplink data and / or uplink to the base station through a physical uplink shared channel (PUSCH). Control signaling. The base station 2 is configured to receive uplink control signaling from the terminal 1 through the PUCCH, receive uplink data and / or uplink control signaling from the terminal 1 through the PUSCH, and send the downlink control channel (Physical Downlink Control Channel, PDCCH) to the terminal 1 through the PUSCH. Sending downlink control signaling, and sending downlink data and paging messages to the terminal 1 through a physical downlink shared channel (PDSCH). The terminal 1 is further configured to receive downlink control signaling from the base station 2 through the PDCCH, and receive downlink data and paging messages from the base station 2 through the PDSCH.

In order to better understand a communication method and device disclosed in the embodiments of the present invention, an application scenario used in the embodiments of the present invention is described below first. In the case that the terminal needs to send uplink data to the base station, in order to reduce the delay caused by requesting the exclusive resource from the base station, the terminal can directly use the resource pre-configured by the base station (that is, the shared resource in the embodiment of the invention) to send the uplink Data, and at the same time, the uplink data may carry a resource request for applying for a dedicated resource, so that the base station may apply for resources while sending the uplink data. After the base station receives the resource request, it can dynamically allocate exclusive resources to the terminal, so that effective integration of time delay and communication efficiency can be achieved. However, in the case where the terminal exclusively enjoys the pre-configured resources, since there is no conflict problem, the terminal does not need to send a resource request to the base station. If the allocated exclusive resources are used after sending a resource request, resources will be wasted instead. Therefore, under the circumstance of being exempt from authorization, whether the terminal needs or does not need to send a resource request to the base station becomes a technical problem to be solved urgently.

Based on the network architecture shown in FIG. 1, please refer to FIG. 2, which is a schematic flowchart of a communication method disclosed in an embodiment of the present invention. As shown in FIG. 2, the communication method may include the following steps.

201. A terminal sends uplink data to a base station through a shared resource.

In this embodiment, when the terminal does not apply for a dedicated resource from the base station, and there are resources (ie, shared resources) pre-configured by the base station for the terminal, when the terminal has uplink data to be sent, it may first send the shared resource to the base station. Uplink data, so that the transmission delay of uplink data can be reduced. The uplink data is one or more uplink data of the uplink data sent by the terminal to the base station through the shared resource.

202. The base station sends instruction information for retransmitting the uplink data to the terminal.

In this embodiment, after receiving the uplink data from the terminal through the shared resource, the base station decodes the uplink data. When the uplink data is successfully decoded, it indicates that the uplink data transmission is successful, and the base station does not send to the terminal for retransmission of the uplink data. Indication information for uplink data. When the uplink data is not decoded successfully, it indicates that the uplink data transmission fails, and the base station sends instructions to the terminal for retransmitting the uplink data. The instruction information for retransmitting the uplink data may carry a sending sequence number of the uplink data that needs to be retransmitted.

203. The terminal sends a resource request to the base station.

In this embodiment, after receiving the instruction information from the base station for retransmitting the uplink data, the terminal may directly send a resource request to the base station. It is also possible to send a resource request to the base station only when the conditions are met.

In this embodiment, the terminal may start the counter when sending the first uplink data to the base station; or it may send M uplink data to the base station, and the M uplink data is received for retransmission. In the case of the indication information of the uplink data, the counter is started only when the M + 1th uplink data is sent to the base station, where M is an integer greater than 1; there may also be M uplink data in the uplink data sent to the base station. The counter is started only after receiving the indication information for retransmitting the uplink data; the counter can also be started when the first indication information for retransmitting the uplink data is received; the counter can also be started at other times This embodiment is not limited. Then, the counter counts the number of times that the instruction information is continuous. After receiving an instruction message, it can be judged whether the received instruction message is continuous with the previous instruction message. When the instruction message is continuous, the counter is increased by one step, which can be 1 or other values. Then continue to judge whether the count counted by the counter is greater than the threshold. When the counted count is greater than the threshold, the terminal sends a resource request to the base station and can set the counter as an invalid counter; when the counted count is less than or equal to the threshold, the shared resource is passed. Send uplink data that needs to be retransmitted to the base station, and continue counting through the counter. When discontinued, the counter is reset first, that is, the counter is cleaned up so that the counter counts again, and then the counter is increased by one step. It is also possible to determine whether the number of times counted by the counter is greater than a threshold when the instruction for retransmitting the uplink data is not received from the base station within a preset period of time after the terminal sends the uplink data, and the terminal reports to the The base station sends a resource request and can set the counter as an invalid counter; when the counted number is less than or equal to the threshold, the counter is reset. The uplink data can carry the sending sequence number of the uplink data sent by the terminal, and the indication information also carries the sending sequence number of the uplink data that needs to be retransmitted, so that the terminal can determine which uplink data needs to be retransmitted, and the terminal can carry it with the indication information. It is determined whether the received instruction information is instruction information for continuously transmitted uplink data.

In this embodiment, the terminal may start a timer and a counter when sending the first uplink data to the base station, or may send M uplink data to the base station, and the M uplink data is received and used. In the case of retransmitting the indication information of the uplink data, the timer and counter are started only when the M + 1th uplink data is transmitted to the base station, where M is an integer greater than 1; the uplink data may also be transmitted to the base station. The counter is started only when M uplink data has received the indication information for retransmitting the uplink data; the counter may also be started when the first indication information for retransmitting the uplink data is received; also The counter may be started at other times, which is not limited in this embodiment. After that, the timer counts and counts the number of times the instruction information is received through the counter. When the timer reaches the first threshold value, it is determined whether the number of times the counter counts during the first threshold time period of the timer is greater than the second threshold value. When the counted number of times is greater than the second threshold, the terminal sends a resource request to the base station. When the counted number of times is less than or equal to the second threshold, the timer and the counter are reset so that the timer restarts counting and the counter restarts counting.

204. The base station sends the information of the exclusive resource to the terminal.

In this embodiment, after the base station receives a resource request from the terminal, it allocates a dedicated resource to the terminal from the unused resources, and sends information about the dedicated resource to the terminal.

205: The terminal sends uplink data to the base station through the dedicated resource corresponding to the information.

In this embodiment, after the terminal receives the information from the proprietary resources of the base station, the terminal sends uplink data to the base station through the dedicated resources corresponding to the information. The uplink data may be uplink data for retransmission and / or newly transmitted Upstream data.

Based on the network architecture shown in FIG. 1, please refer to FIG. 3, which is a schematic flowchart of another communication method disclosed by an embodiment of the present invention. As shown in FIG. 3, the communication method may include the following steps.

301: A terminal sends uplink data to a base station through a shared resource.

In this embodiment, when the terminal does not apply for a dedicated resource from the base station, and there are resources (ie, shared resources) pre-configured by the base station for the terminal, when the terminal has uplink data to be sent, it may first send the shared resource to the base station Uplink data, so that the transmission delay of uplink data can be reduced. The uplink data is one or more uplink data of the uplink data sent by the terminal to the base station through the shared resource.

302. The base station sends the first indication information for retransmitting the uplink data to the terminal.

In this embodiment, after receiving the uplink data from the terminal through the shared resource, the base station decodes the uplink data. When the uplink data is successfully decoded, it indicates that the uplink data is successfully received, and the base station does not send the terminal to retransmit the First indication information of uplink data. When the uplink data is not decoded successfully, it indicates that the reception of the uplink data fails, and the base station sends the first instruction information to the terminal for retransmitting the uplink data. The first indication information for retransmitting the uplink data may carry a sending sequence number of the uplink data that needs to be retransmitted.

303. The base station sends the uplink resource information to the terminal.

In this embodiment, before, after or at the same time as the base station sends the first indication information for retransmitting the uplink data to the terminal, the base station may directly send the uplink resource information to the terminal, and the uplink resource is a dedicated resource. It is also possible to send the uplink resource information to the terminal only when the conditions are met.

In this embodiment, the base station may start the counter when it receives the first uplink data from the terminal; it may also receive the N uplink data from the terminal when all N uplink data needs to be retransmitted. Next, the counter is started only when the N + 1th uplink data from the terminal is received, and N is an integer greater than 1. It is also possible to receive N uplink data from the terminal that needs to be retransmitted. In this case, the counter is started only after receiving uplink data from the terminal. It is also possible to start the counter when it is determined that the first uplink data from the terminal needs to be retransmitted; it can also be other The counter is started at this time, which is not limited in this embodiment. The counter then counts the number of consecutive transmissions of the first indication information. After determining that the uplink data fails to be received, first determine whether the uplink data is continuous with the previous uplink data that failed to receive. In the case of continuity, the counter is increased by one step; then, continue to determine whether the number of consecutive transmissions counted by the counter is greater than the threshold. When the counted number of continuous transmissions is greater than the threshold, the base station sends the uplink resource information to the terminal, and the counter can be set as an invalid counter; when the counted number of continuous transmissions is less than or equal to the threshold, the counter continues to count; In continuous cases, the counter is reset first, and then the counter is incremented by one step. It can also determine whether the number of consecutive transmissions counted by the counter is greater than the threshold when determining that the uplink data is successfully received. When the counted number of consecutive transmissions is greater than the threshold, the base station sends the uplink resource information to the terminal and sets the counter as an invalid counter; When the counted number of consecutive transmissions is less than or equal to the threshold, the counter is reset.

In this embodiment, the base station may start a timer and a counter when it receives the first uplink data from the terminal; it may also receive N uplink data from the terminal, and these N uplink data all need to be repeated. In the case of transmission, the timer and counter are started only when the N + 1th uplink data from the terminal is received. N is an integer greater than 1. You can also have N of the uplink data received from the terminal. In the case where uplink data needs to be retransmitted, the counter is started only after receiving uplink data from the terminal; it can also be started when it is determined that the first uplink data from the terminal needs to be retransmitted. Counter; the counter can also be started at other times, which is not limited in this embodiment. After that, the timer starts counting, and counts the number of times the first instruction information is sent through the counter. When the timer reaches the first threshold value, it is determined whether the number of sending times counted by the counter within the first threshold time period of the timer is greater than Two thresholds. When the number of transmissions is greater than the second threshold, information about uplink resources is sent to the terminal. When the number of transmissions is less than or equal to the second threshold, the timer and the counter are reset so that the timer restarts counting and the counter restarts counting.

In this embodiment, after receiving the uplink data from the terminal through the shared resource, the base station obtains the DMRS of the terminal from the uplink data, and determines whether the DMRS of other terminals has been received through the shared resource. When a DMRS other than the DMRS of the terminal is detected on the resource, it indicates that multiple terminals use the shared resource at the same time, and send information of uplink resources to the terminal.

As a possible implementation manner, after the base station sends the first indication information for retransmitting the uplink data to the terminal, or at the same time, or if the condition is met, or when the number of consecutive transmissions counted by the counter is greater than a threshold, Or when the timer reaches the first threshold and the number of sending times counted by the counter is greater than the second threshold, the terminal may first send second instruction information for instructing the terminal to send a resource request to the base station, so that the terminal can The second indication information sends a resource request to the base station. After receiving the resource request from the terminal, the base station sends information about the uplink resource to the terminal according to the resource request.

304. The terminal sends uplink data to the base station through an uplink resource corresponding to the information.

In this embodiment, after the terminal receives the uplink resource information from the base station, it sends uplink data to the base station through the uplink resource corresponding to the information. The uplink resource is a dedicated resource, and the dedicated resource is used to retransmit the uplink data and / Or newly transmitted uplink data.

In order to better understand a communication method and device disclosed in the embodiments of the present invention, another application scenario used in the embodiments of the present invention is described below first. The current standard protocol defines the restart conditions of the BWP deactivation timer under license-free, that is, the terminal will restart the BWP deactivation timer and restart the BWP deactivation timer each time the terminal sends uplink data using a pre-configured resource (that is, shared resource). The purpose is to prevent the downstream BWP from switching from the current BWP to the default BWP. Generally, the default BWP has a smaller bandwidth than the activated BWP (that is, the working BWP). Therefore, the terminal working under the default BWP can save power better. In the uplink license-free scenario, if the terminal has uplink data to be sent on pre-configured resources, one reason for restarting the BWP deactivation timer may be the hybrid automatic retransmission request for uplink data sent on pre-configured resources (Hybrid Automatic Repeat (request, HARQ) is implemented by monitoring the PDCCH for the corresponding HARQ process on the downlink channel, that is, after the terminal sends uplink data on the pre-configured resources, it needs to monitor on the downlink BWP the PDCCH that may be scheduled for retransmission. . The problem here is that if the terminal restarts the BWP deactivation timer once it sends uplink data on the pre-configured resources, it will cause the terminal to fail to switch to the default BWP. If no retransmission PDCCH has been scheduled on the current BWP Then, letting the terminal stay on the current BWP for a long time is not good for the power consumption of the terminal. In contrast, if the PDCCH is not monitored on the current BWP, it is directly switched to the default BWP to monitor the PDCCH. If there is a PDCCH scheduled for retransmission, it will bring unnecessary BWP switching. Therefore, in the uplink license-free scenario of the terminal, the terminal needs to determine whether and when to switch the BWP becomes an urgent technical problem.

Based on the network architecture shown in FIG. 1, please refer to FIG. 4, which is a schematic flowchart of another communication method according to an embodiment of the present invention. As shown in FIG. 4, the communication method may include the following steps.

401. The terminal sends uplink data to the base station.

In this embodiment, when the terminal has uplink data to be sent, if the terminal does not apply for a dedicated resource from the base station, and there are resources that the base station pre-configured for the terminal (that is, shared resources), the terminal may send the shared resource to the base station. Uplink data, so that the transmission delay of uplink data can be reduced. When the terminal applies for a dedicated resource from the base station, it can send uplink data to the base station through the dedicated resource. The uplink data is one or more uplink data among the uplink data sent by the terminal to the base station.

402. The terminal determines that the uplink data transmission is successful.

In this embodiment, after receiving the uplink data from the terminal, the base station decodes the uplink data. When the uplink data is successfully decoded, it indicates that the uplink data transmission is successful, and the base station does not send an instruction to the terminal to retransmit the uplink data. Information, the terminal determines that the uplink data transmission is successful when it does not receive instruction information for retransmitting the uplink data from the base station within a preset time period after sending the uplink data. When the uplink data is not decoded successfully, it indicates that the uplink data transmission fails, and the terminal is used to send instruction information for retransmitting the uplink data. When the terminal receives the instruction information for retransmitting the uplink data sent from the base station within a preset time period after sending the uplink data, it determines that the uplink data transmission fails.

403. When the condition is met, the terminal switches from the current BWP to another BWP.

In this embodiment, after the terminal determines that the uplink data is sent successfully, it only switches from the current BWP to another BWP when the conditions are met, which can reduce unnecessary BWP switching. Since the current BWP is different from another BWP, the bandwidth width of the current BWP can be greater than the bandwidth width of another BWP. At this time, the power consumption of the terminal can also be reduced; the bandwidth width of the current BWP can also be equal to the bandwidth of another BWP. Width; the bandwidth width of the current BWP may be smaller than the bandwidth width of another BWP.

In this embodiment, the terminal may start the counter when sending the first uplink data to the base station; or in the case where M uplink data is sent to the base station and all the M uplink data are successfully sent, The counter is only started when the M + 1th uplink data is sent to the base station, where M is an integer greater than 1. It is also possible that M of the uplink data sent to the base station received an indication for retransmission of uplink data The counter is started only in the case of information; the counter may also be started when the first indication information for retransmitting uplink data is received; the counter may also be started at other times, which is not limited in this embodiment. After that, the counter counts the number of times that the uplink data is sent successfully. After determining that the uplink data is sent successfully, it can be determined whether this uplink data is continuous with the last uplink data that was successfully sent. If it is determined that the data is continuous, the counter is incremented by one step, and then it is determined whether the number of times the counter counts is greater than the threshold. When the number of counts is greater than the threshold, switch from the current BWP to another BWP, and set the counter as an invalid counter. When the number of counts is less than or equal to the threshold, continue counting through the counter; in discontinuous In this case, the counter is reset first, and then the counter is incremented by one step. When receiving an instruction from the base station for retransmitting uplink data, it can also first determine whether the number of times counted by the counter is greater than a threshold value, and if the number of times counted is greater than the threshold value, switch from the current BWP to another BWP, and Set this counter as an invalid counter, and reset the counter if the counted number of times is less than or equal to the threshold.

In this embodiment, the terminal may start the first timer and counter when sending the first uplink data to the base station, or may send M uplink data to the base station, and receive all the M uplink data. When the indication information for retransmitting uplink data is reached, the first timer and counter are started when the M + 1th uplink data is sent to the base station, where M is an integer greater than 1; it may also be sent to the base station. A counter is started only when M uplink data in the sent uplink data receives the instruction information for retransmitting the uplink data; when the first instruction information for retransmitting the uplink data is received, Start the counter; it can also start the counter at other times, which is not limited in this embodiment. After that, the first timer starts counting and counts the number of successful uplink data transmissions through the counter. When the first timer reaches the first threshold, it is judged whether the number of times counted by the counter is greater than the second threshold. In the case of two thresholds, switch from the current BWP to another BWP. When it is determined that the count counted by the counter is less than or equal to the second threshold, the first timer and the counter are reset, so that the first timer restarts counting and the counter restarts counting.

In this embodiment, after the terminal determines that the uplink data is sent successfully, when the number of times counted by the counter exceeds the threshold, or when the first timer reaches the first threshold and the number of times counted by the counter exceeds the second threshold, the terminal may Set the second timer not to restart first, and switch from the current BWP to another BWP when the current time of the second timer is completed; you can also set the second timer as an invalid timer and switch from the current BWP to another A BWP. The second timer is a BWP deactivation timer.

In one embodiment, after the terminal determines that the uplink data is sent successfully, when the number of times counted by the counter is greater than the threshold, or when the first timer reaches the first threshold and the number of times counted by the counter is greater than the second threshold, The terminal may first send indication information to the base station, and then switch from the current BWP to another BWP. The indication information may instruct the base station to switch from the current BWP to another BWP, may also instruct the base station not to restart the BWP deactivation timer, and may also instruct the base station to invalidate the BWP deactivation timer.

In this embodiment, another BWP may be a default BWP or an initial BWP. When only the initial BWP is configured, the other BWP is the initial BWP. When the initial BWP and the default BWP are configured, another BWP may be the default BWP. When the initial BWP and the default BWP are configured, the current BWP and the default BWP and the size of the initial BWP may be compared first, and the other BWP is a BWP with a smaller bandwidth in the initial BWP and the default BWP.

Based on the network architecture shown in FIG. 1, please refer to FIG. 5, which is a schematic flowchart of another communication method according to an embodiment of the present invention. As shown in FIG. 5, the communication method may include the following steps.

When the terminal applies for a dedicated resource to the base station, it can send uplink data to the base station through the dedicated resource. The uplink data is one or more uplink data among the uplink data sent by the terminal to the base station.

502. The base station determines that the uplink data reception is successful.

In this embodiment, after receiving the uplink data from the terminal, the base station decodes the uplink data. If the uplink data decoding is successful, it is determined that the uplink data is successfully received, and the terminal does not send the instruction information for retransmitting the uplink data. . If the uplink data is not decoded successfully, it is determined that the uplink data reception fails, and the terminal is used to send instruction information for retransmitting the uplink data.

503. When the condition is satisfied, the base station sends instruction information to the terminal.

In this embodiment, after the base station determines that the uplink data is successfully received, when the condition is met, the base station sends instruction information to the terminal to instruct the terminal to switch from the current BWP to another BWP, which can reduce unnecessary BWP switching of the terminal. Since the current BWP is different from another BWP, the bandwidth width of the current BWP can be greater than the bandwidth width of another BWP. At this time, the power consumption of the terminal can also be reduced; the bandwidth width of the current BWP can also be equal to the bandwidth of another BWP. Width; the bandwidth width of the current BWP may be smaller than the bandwidth width of another BWP.

In this embodiment, the base station may start the counter when it receives the first uplink data from the terminal; it may also receive N uplink data from the terminal when all N uplink data needs to be retransmitted. Next, the counter is started only when the N + 1th uplink data from the terminal is received, and N is an integer greater than 1. It is also possible that M uplink data was received for the uplink data sent to the base station. The counter is started only when the indication information of the uplink data is retransmitted; the counter can also be started when the first indication information for the retransmission of the uplink data is received; the counter can also be started at other times. This embodiment Not limited. After that, the counter counts the number of times that the uplink data is sent successfully. When determining that the uplink data is successfully received, first determine whether the uplink data is continuous with the last uplink data that was successfully received. In the case of continuous, the counter is incremented by one step and continues to determine that the uplink data counted by the counter is continuously received successfully. Whether the number of times is greater than the threshold. When the number of times of counting is greater than the threshold, the base station sends instructions to the terminal and sets the counter as an invalid counter. When the number of times of counting is less than or equal to the threshold, the counting continues through the counter; in the case of discontinuities Next, reset the counter first, and then increase the counter by one step counter. It is also possible to determine whether the number of times counted by the counter is greater than the threshold when determining that the uplink data fails to be received. When the number of times counted is greater than the threshold, the base station sends instructions to the terminal and sets the counter as an invalid counter; when the number of counts is less than or When it is equal to the threshold, the counter is reset.

In this embodiment, the base station may start the first timer when receiving the first uplink data from the terminal; it may also receive N uplink data from the terminal, and these N uplink data all need to be re- In the case of transmission, the first timer is started when the N + 1th uplink data from the terminal is received, and N is an integer greater than 1; there may be M uplink data sent to the base station. The counter is started only when the uplink data receives the indication information for retransmitting the uplink data; the counter can also be started when the first indication information for retransmitting the uplink data is received; it can also be other times The start counter is not limited in this embodiment. After that, the first timer starts counting, and uses the first timer to count the length of time that the uplink data is continuously received successfully. When the statistical duration is greater than the threshold, the terminal may directly send instruction information for instructing the terminal to switch from the current BWP to another BWP, and set the first timer as an invalid timer. When determining that an uplink data fails to be received, it may be determined whether the duration counted by the first timer is greater than a threshold. When the duration is greater than the threshold, the base station sends instruction information to the terminal, and the first timer may be set as an invalid timer. When the time duration is less than or equal to the threshold, the first timer is reset.

504. The terminal switches from the current BWP to another BWP.
