As shown in fig. 2, the present embodiment provides a method 200 for reporting continuous reception errors, which can be executed by a receiving end, in other words, the method can be executed by software or hardware installed at the receiving end, and the method includes the following steps.
S202: the receiving end receives the data packet.
The receiving end in each embodiment of the present application may be a terminal, and accordingly, the transmitting end may be a network side device, and may also be other terminals, and the like.
The embodiment can be applied to the scene of periodic communication, that is, a sending end can send a data packet according to a fixed period.
Optionally, the data packet mentioned in each embodiment of the present application includes one of the following: a physical layer Transport Block (TB), a Data Packet initially transmitted by different Hybrid Automatic Repeat Request (HARQ) processes of a physical layer, a Data Packet of the same HARQ process of the physical layer, a Medium Access Control Service Data Unit (MAC SDU), a Radio Link Control Service Data Unit (RLC SDU) of one or more logical channels, and a Packet Data Convergence Protocol Service Data Unit (PDCP SDU).
It is to be understood that the type of the Data packet received by the receiving end is not limited to the above description, and in fact, the Data packet may include a Service Data Unit (SDU) or a Protocol Data Unit (PDU) of each Protocol layer.
In this embodiment, the Physical Channel carrying the data packet may be a Physical Downlink Shared Channel (PDSCH), a Physical Sidelink Shared Channel (psch), or the like.
S204: if the number of the data packets with continuous receiving errors is larger than or equal to N, reporting first information, wherein the first information comprises continuous receiving error indication information; n is an integer greater than or equal to 2.
The packet reception error mentioned in this embodiment may be a packet reception parsing error, or may be a packet timeout. The packet timeout refers to a packet delay greater than a predetermined value, where the predetermined value is smaller than the maximum value of the timer mentioned in the other embodiments.
In this embodiment, the receiving end may count the number of consecutive erroneous reception packets by using a counter, and if the number of consecutive erroneous reception packets is greater than or equal to N, the receiving end is triggered to report the first information to the transmitting end.
Alternatively, the introduction of S204 is equivalent to the following description, or S204 is implemented by the following description: the receiving end counts the continuous receiving error times of the data packet through a counter and the like, and if the continuous receiving error times of the data packet is larger than or equal to N, the receiving end is triggered to report first information to the sending end.
The first information includes continuous reception error indication information, and the first information may be used to notify the sending end of a continuous reception error of a data packet, so that the sending end may adjust a corresponding data packet transmission policy and the like, for example, reduce a Modulation and Coding Scheme (MCS), and further improve a success rate of receiving the data packet at the receiving end.
The first Information may also carry other Information besides the continuous reception error indication Information, for example, the first Information further includes Channel State Information (CSI), and the CSI includes at least one of the following: channel Quality Indicator (CQI), Rank Indicator (RI), Precoding Matrix Indicator (PMI), Modulation and Coding Scheme (MCS) offset value.
The MCS offset value (MCS offset) includes, for example: the difference between the MCS and the received Signal to Interference plus Noise Ratio (SINR) is scheduled.
In various embodiments of the present application, the continuously receiving the error indication information includes at least one of: the ratio of time in the unavailable state to total time, the ratio of time in the available state to total time, the number of consecutive reception error packets, an indication (flag) indicating whether consecutive reception errors occur, the time in the unavailable state (unavailable time), the time in the available state, and statistical information about the consecutive reception error packets.
With regard to the available state, the unavailable state, and the like, reference may be made to the description of the embodiment shown in fig. 3, which will be described later. The statistical information includes, for example: the mean or variance of the number of consecutively received erroneous packets in different time periods, etc.
According to the method for reporting the continuous receiving errors, the receiving end reports the first information under the condition that the number of the data packets with the continuous receiving errors is larger than or equal to N, the first information comprises the continuous receiving error indication information, the transmitting end can conveniently know the transmission condition of the data packets in time, scheduling and the like can be optimized, and the reliability of transmission of the subsequent data packets is guaranteed.
The reporting method for continuous receiving errors provided by the embodiment of the application can be applied to information-physical (cyber-physical) application which generally adopts periodic communication and has strict requirements on transmission timeliness. The embodiment is beneficial to meeting the requirement of Communication Service Availability (CSA) through the timely reporting strategy of the first information, and the transmission reliability is improved.
Embodiment 200 reports the first information when the number of consecutively received erroneous packets is greater than or equal to N. After reporting the first information, if the data packets are still received continuously with errors (there are no data packets that are received successfully), the following two reporting modes may be adopted:
mode 1(mode 1): the first information is not reported any more.
Mode 2(mode 2): and continuing to report the first information.
There are two embodiments of mode 1: one embodiment is as follows: after the first information is reported in the embodiment 200, if the data packet still receives an error, the first information is not reported any more, and the number of data packets that the receiving end continuously receives the error is reset to 1, and then the number of data packets that the receiving end continuously receives the error may be continuously counted, and the first information is reported again when the number of data packets that the receiving end continuously receives the error reaches N again, and then the above steps may be repeatedly executed. The other implementation mode is as follows: after the first information is reported in the embodiment 200, if the data packet still has an error, the first information is not reported any more, and the number of the data packets with errors continuously received by the receiving end is continuously accumulated and counted, and the receiving end is triggered to report the first information under the condition that the number of the data packets with errors continuously received is equal to 2N, 3N, and … ….
In the case of the mode1, the receiving end may count the number of consecutive packets with errors received by the counter, and perform S204 operation of reporting the first information when the count value of the counter is equal to N. If the next data packet is still received wrongly, the counter can count again, the count value of the counter is 1 at this moment, and the number of the data packets which are continuously received wrongly can be continuously counted subsequently; alternatively, the count value of the counter may continue to count up, and subsequently continue to count up the number of packets received with errors. It will be appreciated that in the case where there is a correct packet received, the counter value of the counter may be reset to 0.
In the case of the mode1, the receiving end is triggered to report the first information under the condition that the number of the continuously received erroneous data packets is equal to N, 2N, 3N, … …, and this reporting strategy can save reporting resources and also save resource consumption required by the receiving end to report the first information.
In the case of mode2, the receiving end may count the number of consecutive erroneous packets received by the counter, and perform S204 reporting the first information when the count value of the counter is equal to N. If the next data packet still receives errors, the counter can continue to accumulate and count, and the receiving end is triggered to report the first information every time the next data packet receiving errors is increased by one. It will be appreciated that in the case where there is a correct packet received, the counter value of the counter may be reset to 0.
Under the condition of the mode2, under the condition that the number of the continuously received wrong data packets is equal to N, N +1, N +2 and … …, the receiving end is triggered to report the first information, and the frequent reporting strategy is convenient for the sending end to know the transmission condition of the data packets in time, so that the transmission strategy is adjusted, and the reliability of the transmission of the subsequent data packets is ensured.
Considering that the data packets may not be continuously transmitted, for example, the transmitting end suspends the transmission after continuously transmitting 10 data packets, and continues to transmit the data packets after a certain time interval. In this case, the channel state after the transmission is suspended and the channel state before the transmission is suspended may have changed.
The foregoing embodiments may also control the time interval between two consecutive data packets (regardless of whether the data packets are successfully received) within the duration of the timer when counting the number of consecutive data packets with errors in reception, considering channel variations and the like. Thus, the foregoing embodiments may further include the steps of: in the case of receiving one data packet at each time in S202, the timer may be started or restarted; in case the timer times out, the timer is stopped and the number of consecutively received erroneous data packets is reset to 0.
For example, the duration of the timer is 5ms, the receiving end starts the timer when receiving the first data packet, and the receiving end restarts the timer when receiving the second data packet when the timer runs to 1 ms. After restarting the timer, in case the timer has timed out (i.e. no data packets have been received during the running period of the timer of 5 ms), the timer may be stopped and the number of data packets with continuous reception errors may be reset to 0.
Through the implementation, the time interval between two continuous data packets is controlled within the duration range of the timer, so that the reporting method of continuous receiving errors is more accurate, and a sending end can conveniently implement a more accurate data packet transmission strategy.
Optionally, in various embodiments of the present application, the number of consecutively received erroneous data packets may be counted by a counter. Thus, the foregoing embodiments may also perform the following steps: under the condition that a data packet with a receiving error is detected, if the count value of a counter is smaller than N, the count value of the counter is added by 1; it will be appreciated that the counter value of the counter may also be reset to 0 if correct packet reception is detected. Thus, if the number of the data packets with continuous reception errors at the receiving end is greater than or equal to N, the reporting of the first information in S204 includes: and if the count value of the counter is greater than or equal to N, reporting the first information.
Optionally, before the receiving end receives the data packet in each embodiment, the method further includes the following steps: receiving configuration information, wherein the configuration information is used for configuring at least one of the following 1) to 3).
1) A reporting mode of the first information, wherein the reporting mode is used to instruct the receiving end to: and after the number of the data packets with continuous receiving errors is larger than or equal to N, whether the first information is continuously reported when the data packets still receive errors. The reporting mode may specifically refer to two reporting modes, i.e. mode1 and mode2, described in the foregoing embodiments. Optionally, the reporting mode includes at least one of a mode1 and a mode2, and when the number of the data packets continuously receiving the errors is greater than or equal to N and the data packets still receive the errors, if the reporting mode is in the mode1, the first information is discontinuously reported; and if the reporting mode is the mode2, continuously reporting the first information.
2) A timer for controlling a time interval between two consecutive data packets. The specific implementation process of the timer can be referred to the foregoing embodiments.
3) A counter for counting the number of consecutively received erroneous data packets. The specific implementation process of the counter can be described with reference to the foregoing embodiments.
Optionally, the first information in the embodiments of the present application may be carried through a first channel, where the first channel includes one of: a Physical Random Access Channel (PRACH), a Physical Uplink Control Channel (PUCCH), a unlicensed scheduling Physical Uplink Shared Channel (CG PUSCH), a Physical Uplink Shared Channel (PUSCH), a Physical secondary link Feedback Channel (PSFCH), and a Physical secondary link Shared Channel (psch).
Optionally, the first channel satisfies at least one of the following 1) to 4).
1) The first channel is associated with a channel carrying the data packet.
In this example, Semi-Persistent Scheduling (SPS) for downlink is associated with unlicensed Scheduling (CG), and the first channel may be CG-PUSCH, or the like.
2) If the first channel is a PRACH, the first information is an indication for indicating whether a continuous reception error occurs.
In this example, it is considered that the PRACH cannot carry much information, and therefore, the first information carried by the PRACH is an indication for indicating whether or not continuous reception errors occur.
3) If the first channel is a channel other than the PRACH, the first information includes the continuous reception error indication information, or the first information includes the continuous reception error indication information and CSI.
4) If the first channel is a PUCCH, the resource used by the PUCCH is indicated by Downlink Control Information (DCI), or the resource used by the PUCCH is a configured periodic resource.
When the specific channel is a PUCCH channel, a PUCCH reporting Resource of the first information may be indicated by using a PUCCH Resource Indicator (PRI) field in the DCI; meanwhile, a periodic PUCCH resource may also be configured to feed back the first information.
The foregoing embodiments describe behaviors of the receiving end, and accordingly, the transmitting end (e.g., a network-side device) may have at least one of the following behaviors 1) to 5) after receiving the first information.
1) Open Loop Link Adaptation (OLLA) is adjusted. For example, OLLA is reduced, thereby improving the accuracy of packet reception.
2) And adjusting the scheduling priority of the receiving end according to the first information reported by each receiving end. For example, the first information includes the number of consecutively received erroneous packets, and the transmitting end adjusts the scheduling priority of each receiving end according to the number of consecutively received erroneous packets. Alternatively, the larger the number of consecutively received erroneous packets, the higher the scheduling priority of the receiving end.
3) The scheduled resources are adjusted for the receiving end.
4) The MCS is adjusted. For example, the MCS is lowered, thereby improving the accuracy of packet reception.
5) The DeModulation Reference Signal (DMRS) allocation/allocation is adjusted. For example, DMRS configuration/allocation is improved, and thus, the accuracy of packet reception is improved.
6) Triggering aperiodic CSI measurement and reporting.
7) If the channel is a symmetric channel, it indicates that the uplink SINR is also low, and the receiving end may be instructed to adjust the transmission power. For example, the receiving end is instructed to increase the transmission power.
Optionally, in each of the foregoing embodiments, after the reporting the first information, the method further includes: receiving a data block; wherein, the data block is sent after the sending end adjusts at least one of the following according to the first information: OLLA; MCS; resources scheduled for the receiving end; and DMRS.
Optionally, in each of the foregoing embodiments, after reporting the first information, the method further includes: receiving second information, wherein the second information is generated by a sending end according to the first information, and the second information is used for at least one of the following: triggering the receiving end to execute aperiodic CSI measurement and report; and instructing the receiving end to adjust the transmission power.
To describe the method for indicating a continuous reception error in the embodiment of the present application in detail, two specific embodiments will be described below.
Example one
In this embodiment, the higher layer configures the following parameters for the receiving end, and one set of parameters binds one data packet type.
1) The function of the timer t can be seen in the previous embodiments.
2) The maximum value T of the timer T.
3) The counter n, n defaults to 0. The counter is used to count the number of consecutive erroneous received data packets, as can be seen in the previous embodiment.
4) After the reporting of the first information is triggered, two reporting modes, namely mode1 and mode2, are assigned to the reporting mode when the next packet is still in error.
The receiving end behaviors include:
if the receiving end receives any data packet, the timer can be started or restarted no matter the data packet is successfully received or the data packet is received incorrectly, namely the timer t is reset to 0.
If the data packet is received incorrectly, if the count value N of the counter is less than N, then N is increased by 1. And if N is increased by 1 and is equal to N, triggering to report the first information. If N > is equal to N, if the reporting mode is mode1, N is reset to 1; if the reporting mode is mode2, n is increased by 1 and the reporting of the first message is triggered.
If the data packet is correct, the count value n of the counter is reset to 0.
If T is T, the timer is stopped and the counter value n is reset to 0.

The embodiment can be applied to the scene of information-physical (cyber-physical) application. As shown in fig. 3, the transmitting end periodically transmits a data packet at a certain transmission interval. When a packet (packet) receives an error, the receiver enters a DOWN state, but the communication service of the receiver is still in an available state within a survival time (survivable time), and only when the duration of the DOWN state is longer than the survival time, the communication service of the receiver enters an unavailable state.
In fig. 3, a packet with a reception error (2 nd packet reception error in fig. 3) is not in the disabled state, and two consecutive packet reception errors (4 th and 5 th packet reception errors in fig. 3) are in the disabled state.
In the embodiment shown in fig. 3, N is set to 2, and the maximum value T of the timer T is 5 ms.
In the embodiment shown in fig. 3, when the receiving end receives any data packet, the timer may be started or restarted no matter the data packet is successfully received or the data packet is received incorrectly, that is, the timer t is reset to 0. And triggering the receiving end to report the first information under the condition that the N is equal to 2.
1) After triggering the reporting of the first information, the sending end reschedules the sending policy and sends the data packet, which may specifically refer to the behavior introduction of the sending end in the foregoing embodiment.
2) After the reporting of the first information is triggered, if the next packet still receives an error, it is determined whether to report the first information when N is greater than N according to the mode1 or the mode2 configuration, which may be specifically described in the foregoing embodiments.
3) If the timer is overtime, that is, if a new data packet is not received even when t is 5ms, the timer is stopped, the count value n of the counter is reset to 0, and the timer is restarted until a new data packet is received.
The embodiment improves the transmission reliability of the scene with the requirements on the CSA through a real-time CSA reporting strategy.
