Description

Uplink transmission method, communication equipment and readable storage medium

[ field of technology ]

The present application relates to the field of wireless communications, and in particular, to an uplink transmission method, a communication device, and a readable storage medium.

[ background Art ]

The use scenarios for 5G NR include enhanced mobile broadband (emmbb), large-scale machine type (mctc), ultra-reliable and low latency communications (URLLC). There is also a class of application scenarios between mctc and URLLC that are relatively sensitive to time and relatively low in device complexity, such as industrial internet of things sensors, intelligent monitoring in smart cities, and new internet of things application scenarios for wearable devices.

There is a class of wireless sensor devices in the industrial internet of things (e.g., pressure sensors, humidity sensors, thermometers, motion sensors, accelerometers, actuators, etc.), which are required to be lower than URLLC/eMBB but higher than LPWAN (i.e., LTE-M/NB-IoT) in terms of reliability, performance, device size, cost, battery life, etc. Such/sensor may refer to the definition of the use case of the large-scale Industrial Wireless Sensor Network (IWSN) in 3GPP TR 22.804[1] by the 3GPP architecture group.

Video monitoring equipment in a smart city, 3gpp TR 22.804 describes use cases and requirements for the smart city. Smart cities vertically encompass data collection and processing to more effectively monitor and control urban resources and to provide services to urban residents. Deployment of monitoring cameras is not only an important component of smart cities, but also of factories and industries.

Examples of wearable devices include smart watches, bracelets, devices related to eHealth, and medical monitoring devices, among others.

The industrial internet of things (IIoT, industrial Internet of Things) is characterized in that various acquisition and control sensors or controllers with sensing and monitoring capabilities, mobile communication, intelligent analysis and other technologies are continuously integrated into various links of an industrial production process, so that the manufacturing efficiency is greatly improved, the product quality is improved, the product cost and the resource consumption are reduced, and finally the traditional industry is improved to an intelligent new stage. From the application form, the application of the industrial Internet of things has the characteristics of instantaneity, automation, embedded (software), security, information intercommunication and interconnection and the like.

The time sensitive network (TSN, time Sensitive Network) is a set of standards (IEEE802.1QTSN standards) developed by the institute of electrical and electronics engineers (IEEE, institute of Electrical and Electronics Engineers) for defining the transmission of time sensitive data over wired ethernet and accurate timing references (IEEE 802.3ethernet standards). The precise reference time comes from a central clock source called a "master" (GM) and is distributed between nodes by a series of relays based on a precise time protocol (PTP, precisionTimeProtocol, IEEE1588 precise time protocol).

The NR system acts as a "black box" in the TSN network, as shown in fig. 1. In this way, the TSN provides an accurate time reference for the NR system. The NR system is essentially an IEEE so-called "Boundary Clock" (BC) which acts as a master Clock for all connected nodes (indicated by a dashed box), and is able to allocate the exact time of TSN distribution to user equipments (UE, userEquipment) in all systems.

TSN networks introduce the concept of time-to-live, which refers to the time that a communication service may not meet the requirements of an application before it is considered to enter an unavailable state. If the expected message is not received within a specified time (at least the sum of the maximum allowed end-to-end delay and the lifetime), the system is deemed to be unavailable. In other words, the lifetime refers to the time available for a communication service to recover from a failure, in a manner that represents a distinction between the reliability of the network and the availability of the service.

As shown in fig. 2, if the transmission at time t1 is successful and the next transmission occurs within the lifetime (time period t1 to t 2), a transmission failure at time t2 can be tolerated. When the availability of the service is calculated, the packet loss at the time t2 is not calculated as the packet loss, and the transmission at the time t2 can be skipped even.

If the last transmission (i.e., time t 1) fails, as shown in fig. 3, the transmission at time t2 becomes very important in determining whether a service is available.

As shown in fig. 5, the present application provides an uplink transmission method, where the method is applied to a ue side, and the method includes:

step S100, the continuous failure information is obtained by counting the continuous failure of the uplink transmission of the first service.

The first service includes a service installed or operated when the user equipment is in a state of operation, activation or data transmission, etc., and the service type of the service may be various, which is not limited herein.

The statistics of continuous failures may be set by a timer, a counter, or the like. The execution body for executing the statistics of the continuous failure of the uplink transmission can be executed by the user equipment and reported to the base station, or the base station side can be used for counting the continuous failure of the uplink transmission and sending the statistical result to the base station. The statistical result is continuous failure information. The subject of the statistics may be determined by the base station, higher layer signaling, or a predetermined protocol, as the subject of the statistics is not limited in this regard.

For example, a counter may be introduced to count the number of continuous uplink transmission failures, and when continuous uplink transmission failures are detected, the value of the counter is increased by one; or introducing a timer for counting the continuous uplink transmission failure, and continuing to count when the continuous uplink transmission failure is detected, and the like.

Additionally, the manner of statistics may be by incrementing, decrementing, or otherwise.

Step S110 compares the continuous failure information with a preset threshold, which is determined according to the lifetime of the first service.

The preset threshold may be set by the ue or by the base station. If the preset threshold is set by the user equipment, the user equipment can upload the preset threshold to the base station, and if the preset threshold is configured by the base station, the base station can issue the preset threshold to the user equipment.

In addition, the preset threshold is determined according to the lifetime of the first service. The preset threshold value may be a value greater than, less than or equal to (including greater than or equal to, less than or equal to) the survival time, or may be configured according to the actual scenario and the actual requirement, etc.

The survival time can be issued to the user equipment by the base station end, or the user equipment is set by itself and reported to the base station end, or the base station can determine the survival time by itself according to the information of the user equipment, or the base station obtains from the core network, etc. The lifetime may be carried by the UE auxiliary information TSCAI, and details of the explanation about TSCAI and steps in this embodiment may refer to schemes one to eight.

If the continuous failure information comprises the residual times of the continuous failure acceptable by the first service, a preset threshold is a minimum value of the residual times; if the continuous failure information comprises the number of the residual transmission intervals of the continuous failure acceptable by the first service, a preset threshold is the minimum value of the number of the residual transmission intervals; or the continuous failure information comprises the residual duration of the continuous failure acceptable by the first service, and the preset threshold value is the minimum value of the residual duration. Step S120, if the continuous failure information reaches the preset threshold, the priority information of the subsequent uplink transmission of the first service at least once is turned up.

It should be noted that, the execution body for raising the priority of the subsequent uplink transmission may be a base station or a user equipment. The adjustment of the priority information includes adjusting the priority of the subsequent uplink transmission, uplink transmission control information such as LCP constraint, etc., and the means for adjusting the priority information may also be changed according to the changes of the protocol, the system, the actual scene, etc., which is not limited herein.

Step S130 performs subsequent uplink transmission of the first service at least once according to the adjusted priority information.

If the priority is adjusted for the base station, the base station needs to instruct the user equipment through downlink transmission according to the adjusted related information, so that the user equipment performs subsequent uplink transmission corresponding to the first service at least once according to the adjusted priority information. If the user base station is self-adjusted, uplink transmission can be directly carried out according to the adjusted priority information.

In addition, the first service may be one or a plurality of services.

s0, the UE sends UE auxiliary information TSCAI to the gNB;

1) The UE auxiliary information TSCAI comprises survivin time, PDB and the like expressed by a time period length;

s1, gNB sends configuration information including a preset threshold to UE;

1) The threshold value indicates the duration of the maximum continuous uplink transmission failure that the UE can tolerate;

2) The configuration information may include an initial value Tinit, a threshold value Tthr, etc. of the timer;

s2, the UE performs uplink transmission;

1) If the uplink transmission failure statistics Timer has started timing and does not reach the preset threshold, continuing to perform timing according to a detection result; otherwise, resetting the timer, namely resetting or copying the initial value in the configuration information acquired from the gNB, starting the timer to start timing, and executing a continuous uplink transmission failure statistics process;

1) The continuous uplink transmission failure detection process is similar to the step 3 of the scheme II, and if ack feedback information is received, the timer stops timing; otherwise, receiving nack feedback information or overtime of a timer for detecting packet loss, indicating that the uplink transmission fails, wherein the timer does not stop timing;

2) Optionally, the initial value of Timer may be 0 or 1, or the corresponding value Tinit in the configuration information;

3) Alternatively, the Timer may be clocked in an incremental manner or in a decremental manner;

a. if the Timer counts up in an incremental manner, when the value of the Timer is greater than or equal to a preset threshold Tthr, the continuous uplink transmission failure statistics result reaches the preset threshold; or (b)

c. when the Timer counts down, the preset threshold value may be an initial value of the Timer;

S5, if the statistical result reaches the preset threshold, the UE adjusts the priority of the next uplink transmission or configuration information such as LCP constraint and the like;

s6, the UE performs the next uplink transmission according to the configuration information such as the adjusted uplink transmission priority.

[ scheme IV ]

The difference of the scheme is that when the UE detects that the statistics result of continuous uplink transmission failure reaches a preset threshold in the scheme, the UE reports the statistics result to the gNB, and the gNB schedules the next uplink transmission, including the information of uplink transmission resource UL Grant, scheduling information, priority information, LCP constraint and the like. And the UE executes the next uplink transmission according to the scheduling information of the gNB.

Uplink transmission based on base station scheduling as shown in fig. 19

Steps 1 to 5 of this embodiment are the same as those described above, and may be any one of the embodiments described above or any combination of the steps of the embodiments described above.

S6, the UE reports the continuous uplink transmission failure statistical result to the base station;

2) As an indication information, the gNB schedules the next or subsequent uplink transmission of the UE for several times; or (b)

3) For scheduling requests and the like, the patent does not limit the concrete content expression form;

S7, the base station sends control information of the next uplink transmission or the subsequent uplink transmission of the UE to the UE;

1) The uplink transmission control information may be uplink transmission resources, such as UL Grant, or priority information, scheduling information, LCP constraints, etc.;

2) May be transmitted in the form of signaling, such as DCI, etc.;

s8, the UE performs the next or subsequent uplink transmission for a plurality of times according to the uplink transmission control information issued by the gNB.

[ scheme five ]

As shown in fig. 20, the scheme is mainly aimed at the situation that the periodicity < (<=) duration is <2 x periodicity, i.e. the service can only tolerate one packet loss. For this case, the UE does not need to count continuous uplink transmission failure information, and as long as one uplink transmission failure is detected, priority adjustment needs to be performed on the next transmission, where the adjustment may be performed by the UE autonomously or by the gNB to perform adjustment on the next transmission of the UE through uplink transmission control information.

The principle is the same as the foregoing solution, and the packet loss detection may be judged by the timer timeout or indicated by feedback sent by the gNB:

1) When the UE executes uplink transmission, the timer starts to count, and if the timer is overtime and ack feedback information sent by the gNB is not received, the uplink transmission fails; or (b)

2) The UE receives the nack feedback information, and the transmission fails;

3) After detecting failure of uplink transmission, the UE can autonomously adjust the priority of the next or subsequent uplink transmission and LCP constraint information or report the adjustment to the gNB, and uplink transmission control information issued by the gNB indicates scheduling information such as priority adjustment information of the next or subsequent uplink transmission; or (b)

4) And detecting whether the transmission is successful or not by the gNB, and when the gNB does not receive the uplink transmission sent by the UE in a receiving window (or before the time-out of a timer at the gNB side), directly issuing uplink transmission control information by the gNB, and adjusting scheduling information such as the priority of the subsequent uplink transmission of the UE, wherein the uplink transmission control information can contain nack feedback to indicate the failure of the transmission.

[ solution six ]

The scheme is mainly used for supplementing the scheme:

1) The uplink transmission of the UE may include control information of the next uplink transmission, where the control information may include time-frequency resources of the next uplink transmission, etc., and instruct the gNB to receive the next uplink transmission in a designated receiving window, and if the gNB does not receive the next uplink transmission in the receiving window, the next uplink transmission is overtime or fails in packet loss;

2) The gNB can include the allowance of survivinal time or the preset threshold value in the feedback information, namely how many times or how long the service can tolerate continuous uplink transmission failure, and the allowance or the preset threshold value is used for the UE to adjust a timer or a counter;

3) The gNB can not feed back each uplink transmission, and can use one ack information to indicate that the previous continuous transmission is successful for a plurality of times, or use one indication information to indicate that the previous continuous uplink transmission is failed for a plurality of times;

4) The continuous uplink transmission failure can be detected and counted by the gNB, when the gNB detects that the continuous uplink transmission failure reaches or exceeds a certain threshold value for a plurality of times, the gNB can issue uplink transmission control information, and schedule information such as the priority of the next or subsequent uplink transmission for a plurality of times is regulated, so that the indicated uplink transmission is ensured to be successful, and the service is prevented from being stopped;

5) The gNB can measure uplink transmission delay (per-packet delay) and issue the measurement result to the UE; conversely, the UE may measure the uplink transmission delay and send the uplink transmission delay to the gNB;

6) Optionally, when the success of the uplink transmission is detected, the priority of the subsequent uplink transmission can be reduced; or counting the success of continuous uplink transmission, and reducing the priority of subsequent uplink transmission when the success statistics information of the continuous uplink transmission reaches a certain preset threshold value so as to improve the utilization rate of resources.

[ scheme seven ]

In this embodiment, mainly, in the case of a collision between uplink transmissions of the service and other uplink transmissions of the UE, that is, a collision (intra-UE Prioritization) between different uplink transmissions in the UE, when the uplink transmission resource (such as PUSCH resource) and other uplink transmission resource are overlapped (overlapping) in transmission, if the service can tolerate the failure or delay of the current uplink transmission, the priority of the current uplink transmission is reduced, and other uplink transmissions are preferentially transmitted, or the service skips the current uplink transmission and does not execute the current uplink transmission. Otherwise, if the service cannot tolerate the failure of the uplink transmission, the uplink transmission of the service is sent (priority) preferentially.

As shown in fig. 21, the UE detects the uplink transmission failure of the service, counts the number of continuous uplink transmission failures or duration, and determines whether the counted result reaches a preset threshold. When the uplink transmission of the service collides with the uplink transmission of other services on the UE, if the continuous uplink transmission failure statistical result of the service does not reach the preset threshold, the priority of the current uplink transmission of the service is reduced, the current uplink transmission is suspended or delayed, or the current uplink transmission is skipped, or the corresponding LCH is forbidden to carry out uplink transmission. If the continuous uplink transmission failure statistical result reaches the preset threshold, the uplink transmission of the service is preferentially sent, so that the success of the uplink transmission of the service is ensured, and the service is prevented from being stopped.

Steps 0 to 2 of the scheme are similar to the previous scheme:

s3, determining whether to reduce the priority of the uplink transmission or skip the uplink transmission according to the measurement result of continuous uplink transmission failure;

1) Judging whether the continuous uplink transmission failure statistical result reaches a preset threshold, if so, preferentially sending the uplink transmission of the service to avoid the service from entering a shutdown state; otherwise

2) If the statistical result of the continuous uplink transmission failure does not reach the preset threshold, that is, the service can tolerate the uplink transmission failure, the priority of the uplink transmission is reduced, the next uplink transmission opportunity is waited to send, or (skip) skips the uplink transmission, and the uplink transmission is not executed;

3) Optionally, the uplink transmission failure detection and continuous uplink transmission failure statistics operation and the judgment of whether the continuous uplink transmission failure statistics result reaches the preset threshold may be performed by the UE itself or by the gNB;

4) Optionally, the adjusting the priority of the current uplink transmission or determining whether to skip the current uplink transmission may be autonomously determined by the UE or performed by the UE under the direction of the gNB;

s4, carrying out uplink transmission according to the determination of the third step.

[ scheme eight ]

Based on the above scheme, the scheme establishes a mapping relation between the continuous uplink transmission failure statistical result (or the allowance of continuous uplink transmission failure which can be tolerated by the service) and scheduling information such as uplink transmission priority. And the UE adjusts the information such as the priority of the subsequent uplink transmission or uplink transmission for a plurality of times according to the detected and counted continuous uplink transmission failure result, so that the probability of success of the subsequent uplink transmission is improved, and the service is prevented from entering a shutdown state.

As shown in fig. 22, a mapping relationship between the continuous uplink transmission failure statistics and the uplink transmission priority is established:

in the scheme, uplink transmission failure detection, continuous uplink transmission failure statistics and related configuration information are the same as those in the previous scheme:

s1, UE acquires configuration information from gNB;

1) Judging which two adjacent threshold values the continuous uplink transmission failure statistical result is between, and determining the priority of the subsequent uplink transmission, control information required by uplink transmission such as LCP constraint and the like according to the mapping relation between the threshold values or the threshold intervals and the uplink transmission priority;

2) Adjusting control information of subsequent uplink transmission according to the determined uplink transmission control information;

3) Optionally, the determining of the uplink transmission control information may be performed by the UE autonomously or by the base station, and the uplink transmission control information is sent to the UE;

s4, the UE performs uplink transmission according to the new uplink transmission priority information;

1) And the UE executes uplink transmission according to the latest adjusted uplink transmission control information.
