Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with aspects of one or more embodiments of the present description as detailed in the accompanying claims.

One or more embodiments of the present disclosure send an activation signal and a notification message to a radio resource scheduling device through a UE (User Equipment), or request a radio communication resource to the radio resource scheduling device, so that the radio resource scheduling device determines that the UE has a continuous data transmission requirement in the specific time period, thereby ensuring that the UE can realize continuous data transmission in the specific time period by maintaining the radio communication resource allocated to the UE or continuously allocating the radio communication resource to the UE, and avoiding a data transmission delay caused by radio resource management.

For further description of one or more embodiments of the present specification, the following embodiments are provided:

fig. 1 is a schematic diagram of a communication system according to an exemplary embodiment. As shown in fig. 1, the communication system may include a radio resource scheduling device 11 and a user device 12, a user device 13, a user device 14, etc., where the radio resource scheduling device 11 may schedule corresponding radio communication resources to the user device 12, the user device 13, the user device 14, etc. by using a radio resource management technology in the related art, so that the user device 12, the user device 13, the user device 14, etc. implement corresponding radio communication functions; among them, there may be various implementation forms of radio resource management techniques, such as RRC (Radio Resource Control ), RRM (Radio Resource Management), etc., which are not limited in this specification.

Due to the radio resource management technology in the related art, improper scheduling of radio communication resources may be caused in the process of implementing continuous data transmission by the UE, resulting in too high delay of data transmission. Thus, in the embodiments of the present disclosure, the latency problem that may be caused by the radio resource management technology may be improved by improving the communication scheme.

Fig. 2A is a flow chart of a communication method according to an exemplary embodiment. As shown in fig. 2A, the method may include the steps of:

in step 202A, a user equipment transmits an activation signal to a radio resource scheduling device in a specific time period, so that a data transmission delay of the user equipment in the specific time period is smaller than a data transmission delay when the activation signal is not transmitted.

In an embodiment, by sending an activation signal to the radio resource scheduling device by the user equipment in a specific time period, on one hand, the user equipment can determine that there is a data transmission requirement for itself continuously, so as to avoid entering a sleep state or a sleep state through a radio resource management mechanism, and ensure that the user equipment can continuously implement data transmission, and on the other hand, the radio resource scheduling device can determine that there is a data transmission requirement for the user equipment in the specific time period according to the activation signal, so that even if the data transmission requirement of the user equipment does not continuously exist in practice, and the data transmission operation is not continuously performed, it can ensure that the radio resource scheduling device keeps the radio communication resource allocated to the user equipment in the specific time period, and avoids releasing the radio communication resource, thereby enabling the user equipment to implement corresponding data transmission operation through the radio communication resource, and avoiding that the release and rescheduling processes of the radio communication resource by the radio resource scheduling device result in a larger data transmission delay.

In an embodiment, the radio resource scheduling device may include any device for implementing a radio communication resource scheduling function, for example, a base station, a wireless gateway, a radar, a satellite, and the like, which is not limited in this specification.

In an embodiment, the radio resource scheduling device implements scheduling of radio communication resources according to a predefined management scheduling period or a resource holding period, where the management scheduling period is a period for implementing radio communication resource scheduling management, and the resource holding period is a holding period of radio communication resources allocated to a UE, and releases radio communication resources allocated to the UE after the resource holding period expires, so that the management scheduling period or the resource holding period may be related to a timer of a preset duration; if the timer is overtime, it is determined that the current management scheduling period is over, and the wireless communication resources allocated to the user equipment need to be released, and if the user equipment has a data transmission requirement before the timer is overtime, the wireless resource scheduling device resets the timer to recalculate the current management scheduling period.

In one case, the ue may ensure that the transmission interval of the activation signal is not greater than at least one management scheduling period or at least one resource holding duration of the radio communication resource by the base station, so that before the end of the current management scheduling period or resource holding duration, the ue can always communicate that there is still a data transmission requirement to the radio resource scheduling device by the activation signal, so that the radio resource scheduling device resets the timer, recalculates the current management scheduling period or resource holding duration, and avoids the release of the radio communication resource allocated to the ue.

In another case, the transmission interval of the activation signal by the ue may be greater than the management scheduling period and the resource holding duration of the radio communication resource by the ue, so that although the radio communication resource may be released during a part of the management scheduling period or the resource holding duration in the specific period, it may still be ensured that the activation signal can act on at least a part of the management scheduling period or the resource holding duration in the specific period, thereby improving the data transmission delay problem of the ue. When the transmission interval of the activation signal is greater than at least one management scheduling period or resource holding duration, the data transmission delay of the user equipment may be increased along with the continuous increase of the transmission interval until the activation signal is increased and the data transmission delay of the user equipment cannot be improved; for example, in an embodiment, the transmission interval of the activation signal may be not greater than 10 times of the maximum management scheduling period or the maximum resource holding duration, so as to ensure that the data transmission delay improvement of the activation signal to the ue is not reduced to be too low, which is not limited in this specification.

In an embodiment, the activation signal may include a pulse signal, where the pulse signal has a simple data structure and a small data size, which can reduce the occupation of the computing resource of the ue, reduce the occupation of the wireless communication resource, and avoid excessive overhead caused to the wireless resource scheduling device. In other embodiments, the activation signal may include any signal, such as a periodic data signal or an aperiodic data signal, as long as the radio resource scheduling device can determine that the user equipment has a data transmission requirement, which is not limited in this specification.

In an embodiment, the transmission of the activation signal by the user equipment may be periodic or aperiodic, and may be selected according to the actual situation, which is not limited in this specification.

In an embodiment, the user equipment may generate the activation signal based on the application layer, and sequentially transmit the activation signal to the underlying protocol by the application layer, so as to finally implement sending the activation signal. By generating and sending the activation signal at the application layer, a developer can realize the technical scheme of the specification through an operating system or an application program without involving a protocol layer at the bottom layer, so that the application threshold and the implementation difficulty of the technical scheme of the specification are greatly reduced.

In an embodiment, the user equipment may generate the activation signal based on any one of the following protocol layers: a presentation layer, a session layer, a transport layer, a network layer, a data link layer, a physical layer; in other words, the user equipment may generate the above-described activation signal based on an arbitrary protocol layer, which is not limited in this specification as long as the activation signal can be transmitted to the radio resource scheduling device.

In an embodiment, the specific time period may include any time period, and the present specification is not limited in terms of appearance timing, duration, and the like of the time period. For example, when a certain application or a certain service has a higher delay requirement, the time period for the application or the service to implement data transmission can be taken as the specific time period, and the wireless resource scheduling device is ensured to keep the wireless communication resource through the embodiment of the specification, so that the delay requirement of the application or the service is met.

For example, fig. 2B is a flowchart of a communication method for large data transmission according to an exemplary embodiment. As shown in fig. 2B, the method may include the steps of:

in step 202B, the ue monitors data to be transmitted.

In step 204B, when the data amount of the data to be transmitted reaches the preset data amount, the ue sends an activation signal to the radio resource scheduling device in a specific time period, so that the data transmission delay of the ue for the data to be transmitted in the specific time period is smaller than the data transmission delay when the activation signal is not sent.

In an embodiment, when the data amount of the data to be transmitted reaches the preset data amount, the data to be transmitted may not be transmitted through a single data packet or a smaller number of data packets, but must be divided into a larger number of data packets, so that in the process of transmitting the data to be transmitted, by sending an activation signal to the radio resource scheduling device, it is ensured that the data packets can be continuously transmitted, and interruption and delay in the process of transmitting the data packets by the radio resource manager are avoided.

In an embodiment, the preset data amount may be not greater than the data amount of a single data packet, so as to ensure that all data to be transmitted can be transmitted continuously, without delay or with low delay; or the preset data volume can be slightly larger than the data volume of a single data packet, so that continuous transmission of at least a part of the data packets can be realized, and better balance between data transmission delay reduction and user equipment power consumption control can be realized.

In one embodiment, when an application is opened from a closed state, the transfer of large amounts of data is involved at the instant the application is opened for page loading of the application. Therefore, through the embodiment of the specification, the continuous transmission of the data can be realized, so that the data transmission time delay caused by the radio resource management is reduced or avoided, the loading speed of an application program interface is improved, and the waiting time of a user is shortened.

For another example, fig. 2C is a flowchart of a communication method for high real-time data transmission requirements according to an exemplary embodiment. As shown in fig. 2C, the method may include the steps of:

in step 202C, the ue monitors data to be transmitted.

In step 204C, when the data to be transmitted belongs to a preset service, the ue sends an activation signal to the radio resource scheduling device in a specific time period, so that the data transmission delay of the ue for the data to be transmitted in the specific time period is smaller than the data transmission delay when the activation signal is not sent.

In an embodiment, when the data to be transmitted belongs to a preset service, such as a payment service, a live broadcast service, an online interaction service, an authentication service, and the like, the services often have higher real-time requirements and security requirements, and the continuous transmission of the data to be transmitted can be realized through the embodiment, so that the data transmission delay caused by radio resource management is reduced or avoided, the data transmission requirements of the preset service are met, including the meeting of the real-time requirements, the reaction speed of the preset service is improved, and the security requirements of the service are met by reducing the delay.

The following describes in detail the delay improvement in the scheduling of radio communication resources according to the embodiments of the present disclosure, taking the DRX (Discontinuous Reception ) mechanism adopted by the RRC technology as an example.

Fig. 3 is a schematic diagram of a DRX mechanism provided by an exemplary embodiment. The DRX entity configured on the UE is located in the MAC (Media Access Control, medium access control) layer of the protocol stack, and determines whether the UE has a data transmission requirement by sending an instruction to the physical layer to inform the physical layer to monitor the PDCCH channel (Physical Downlink Control Channel ).

As shown in fig. 3, the DRX entity maintains a DRX timer (e.g., DRX Inactivity Timer, DRX deactivation timer) so that the DRX entity can send an instruction to the physical layer before the DRX timer expires, so that the physical layer monitors the PDCCH channel; when the monitoring result is that the UE has a data transmission requirement (e.g. discovers new downlink data or uplink grant, etc.), the DRX timer is reset after completing data transmission, so as to continue to maintain monitoring the PDCCH channel.

When the monitoring result is that the UE does not have data transmission requirement, the DRX timer is normally timed until the time-out. After the DRX timer times out, several short DRX cycles (short DRX cycles) shown in fig. 3 are entered, the DRX timer stops counting, each short DRX cycle includes a listening period (On Duration) and a sleep period (Opportunity for DRX), wherein the PDCCH channel may be monitored during the "listening period" to find out the data transmission requirement that the UE may exist, and is not monitored during the "sleep period". If the monitoring period in a certain short DRX period monitors that the UE has data transmission requirement, data transmission can be implemented, and the DRX timer is restarted to return to the previous flow; if the UE is not monitored for data transmission requirements during the "listening period" of these several short DRX cycles, a long DRX cycle may be entered. The long DRX cycle is similar to the structure of the short DRX cycle, and also includes a listening period and a sleep period, which are not described herein.

Thus, if the UE continuously performs data transmission, continuous monitoring of the PDCCH channel may be achieved by continuously resetting the DRX timer. However, the DRX timer set in the related art is often short, such as only 100ms or less, and even when there is a continuous data transmission requirement for the UE, it is likely that an interval between adjacent data transmission operations is greater than 100ms, resulting in the DRX timer timing out, thereby entering a "sleep period" of a short DRX cycle or a long DRX cycle.

For example, fig. 4 is a schematic diagram of a data transmission procedure based on a DRX mechanism according to an exemplary embodiment. As shown in fig. 4, taking data transmission between a UE and an eNodeB (Evolved Node B, i.e., a base station in an LTE network) as an example, when a DRX entity monitors that the UE generates uplink data 1, the UE sends uplink data to the eNodeB using allocated radio communication resources, and a DRX timer resets after the uplink data is sent, so as to continuously monitor a PDCCH channel to determine a data transmission requirement of the UE, and the eNodeB sends the uplink data 1 to a server, receives downlink data returned by the server, and returns the downlink data to the UE; when the DRC entity monitors that the UE has the receiving requirement of the downlink data, the UE receives the downlink data by using the allocated wireless communication resources and resets the DRX timer after the receiving operation is completed.

Assuming that the interval at which the UE retransmits the uplink data is slightly longer, the DRX entity does not monitor that the UE completes data transmission before the DRX timer expires, and will sequentially shift to the above-mentioned short DRX cycle, long DRX cycle, etc., resulting in the release of the radio communication resources that were originally allocated to the UE by the eNodeB. Then, if the UE generates new uplink data 2 just in the "listening period", the transmission of the uplink data 2 can be resumed as soon as possible, and the DRX timer is restarted and the previous procedure is returned, but since the "listening period" is relatively short and the "sleep period" is relatively long, the UE has a higher probability of generating new uplink data 2 in the "sleep period", so that the UE must wait for the "sleep period" to end and enter the latest "listening period", and then can regain the scheduled wireless communication resource and realize the transmission of the uplink data 2, but obviously causes longer waiting and data transmission delay in the waiting process of the "sleep period".

Fig. 5 is a schematic diagram of a data transmission process using an activation pulse according to an exemplary embodiment. As shown in fig. 5, to avoid that the UE enters a "sleep period" during continuous data transmission due to the interval between adjacent data transmission operations being greater than the DRX timer, an activation pulse may be continuously generated by the UE, and by sending the activation pulse to the eNodeB, the DRX entity determines that the UE continuously sends uplink data 1, uplink data 2, etc., so that the DRX timer is continuously reset and does not enter the "sleep period".

For example, assuming that the operation duration of the DRX timer is 100ms, the activation pulse may be set to be periodically transmitted at intervals such as 40ms, 80ms, 99ms, etc. (not more than 100 ms), so that after the DRX timer is restarted at a certain time, the activation pulse may be necessarily transmitted before the DRX timer times out to implement the reset of the DRX timer. Of course, the activation pulses may be transmitted aperiodically, as long as the transmission interval of adjacent activation pulses is made smaller than the operation duration of the DRX timer by 100 ms.

In the embodiment of the present specification, the UE may generate the above-mentioned activation pulse based on any protocol layer, which is not limited in the present specification. For example, a device vendor of the UE may generate an activation pulse based on an underlying protocol such as a physical layer, a data link layer, a network layer, or the like, or an upper layer protocol such as a transport layer, a session layer, a presentation layer, an application layer, or the like may be used across layers, and an operating system developer or an application program developer may generate the activation pulse through the upper layer protocol such as the application layer, or other underlying protocol, so that embodiments of the present disclosure have a great applicable scenario and scope.

Fig. 6 is a flowchart of a communication method based on a ue side according to an exemplary embodiment. As shown in fig. 6, the method may include the steps of:

Step 602, the ue sends a notification message to the radio resource scheduling device, where the notification message includes a hold identifier, where the hold identifier is used to instruct the radio resource scheduling device to hold the radio communication resources allocated to the ue for a specific period of time.

In one embodiment, the specific time period may be a time period specified by a communication protocol. For example, the specific time period may include: within 2s after receiving the notification message, etc.

In an embodiment, the specific time period may be a time period that the user equipment temporarily negotiates with the radio resource scheduling device. For example, the notification message may also contain a hold duration such that the particular time period may include: and the time period with the sending time or the receiving time of the notification message as the starting time and the holding time as the duration. For another example, the ue may send a termination message to the radio resource scheduling device, where the termination message includes a termination identifier, where the termination identifier is used to instruct the radio resource scheduling device to terminate the maintenance of the radio communication resource allocated to the ue, that is, the termination time of the specific period of time may be the time when the radio resource scheduling device receives the termination message (specifically, the time when the termination identifier is resolved).

In an embodiment, the specific time period may not set the termination time in advance until the radio resource scheduling device receives the termination message sent by the user equipment. In another embodiment, the specific time period may be preset as the termination time, and if the radio resource scheduling device receives the termination message within the specific time period, the specific time period may be terminated in advance even if the preset termination time has not yet been reached.

In an embodiment, the termination time of the specific time period may include a transmission time or a reception time of the termination message. For example, the ue may use the sending time of the termination message, and the radio resource scheduling device may use the receiving time of the termination message.

Fig. 7 is a flowchart of a communication method based on a radio resource scheduling device side according to an exemplary embodiment. As shown in fig. 7, the method may include the steps of:

in step 702, the radio resource scheduling device receives a notification message sent by the user equipment.

In step 704, when the notification message includes a hold identifier, the radio resource scheduling device holds the radio communication resource allocated to the user equipment for a specific period of time.

In an embodiment, the specific time period may be a time period that the user equipment temporarily negotiates with the radio resource scheduling device. For example, the notification message may also contain a hold duration such that the particular time period may include: and the time period with the sending time or the receiving time of the notification message as the starting time and the holding time as the duration. For another example, the radio resource scheduling device may receive a termination message sent by the ue, and when the termination message includes a termination identifier, the radio resource scheduling device may terminate the maintenance of the radio communication resource allocated to the ue, that is, the termination time of the specific period may be the time when the radio resource scheduling device receives the termination message (specifically, the time when the termination identifier is resolved).

In the embodiments shown in fig. 6 to 7, the user equipment does not need to continuously transmit the activation signal to the radio resource scheduling device, but can enable the radio resource scheduling device to maintain the radio communication resource by transmitting the notification message. Similar effects to those of the embodiment shown in fig. 2A can be achieved by the embodiments shown in fig. 6 to 7, and also can be verified by the above-described DRX mechanism, and the description will not be repeated here.

The technical solution shown in fig. 6-7 is described in detail below in connection with fig. 8. Fig. 8 is a flow chart of an exemplary embodiment for improving data transmission delay caused by radio resource management. As shown in fig. 8, taking as an example a data transmission procedure between a UE and an eNodeB, the procedure may include the following steps:

in step 802, the ue monitors itself that a continuous upload need is triggered.

In step 804, the ue sends a notification message to the eNodeB, which contains the hold identities mentioned in the embodiments shown in fig. 6-7 above.

In an embodiment, the notification message may be an interactive message defined by a communication protocol in the related art, and at least one reserved bit in the interactive message is used to represent the hold identifier, or a field originally used for carrying other content in the interactive message is modified to represent the hold identifier, which is not limited in this specification.

In one embodiment, the notification message may be a redefined new interaction message that differs from the communication protocol of the related art and is used by at least one field in the message to characterize the hold identifier.

In an embodiment, when receiving the notification message including the holding identifier, the eNodeB may start a timer with a specific duration, and in a specific period of time running the timer, keep the uplink and downlink resources allocated to the UE, so as to avoid the release of the uplink and downlink resources due to a radio resource scheduling mechanism, and ensure that the UE can use the uplink and downlink resources to realize continuous data transmission and reduce the data transmission delay.

In step 806, the ue detects that uplink data 1 is generated.

In step 808, the ue transmits uplink data 1 to the eNodeB using the allocated radio communication resources.

In step 810, after receiving the uplink data 1, the enodeb sends the uplink data 1 to the server.

In step 812, the enodeb receives the downlink data returned by the server.

In step 814, the enodeb transmits the downlink data back to the UE for reception and processing by the UE.

In step 816, the ue detects the generation of uplink data 2.

In step 818, the ue sends uplink data 2 to the eNodeB using the allocated radio communication resources.

In an embodiment, if the UE is in the running process of the eNodeB-initiated timer when it detects that the uplink data 2 is generated, the eNodeB maintains the uplink and downlink resources allocated to the UE, so that the UE can directly transmit the uplink data 2 by using the uplink and downlink resources, without re-applying for and allocating the wireless communication resources, and avoiding the data transmission delay caused by the re-applying for and allocating the wireless communication resources.

In step 820, the ue determines that the continuous upload is ended.

In step 822, the ue sends a termination message to the eNodeB, the termination message including the termination identity mentioned in the above embodiments.

In an embodiment, the eNodeB started timer may not set the termination time so that the eNodeB only terminates the timer when receiving the termination message sent by the UE.

In an embodiment, the eNodeB started timer may be set with an expiration time, so that the eNodeB may wait for the timer to expire and stop maintaining the uplink and downlink resources allocated to the UE. The termination time can be predefined in the communication protocol without negotiation between the UE and the eNodeB; or, the UE may inform the eNodeB to set the termination time through the notification message, for example, the UE may directly set a termination time, or the UE may set a duration time, so that the eNodeB determines the corresponding termination time according to the start time (for example, the time when the eNodeB receives the notification message, the time when the hold identifier is resolved, or other time) and the duration time.

In an embodiment, the timer started by the eNodeB may be set with a termination time, but if the UE can determine that the continuous uploading ends in advance, the UE may still send a termination message to the eNodeB, and even if the timer has not timed out, the eNodeB may also terminate the operation of the timer in advance according to the received termination message, so as to avoid wasting radio communication resources.

Fig. 9 is a flow chart of another communication method according to an exemplary embodiment. As shown in fig. 9, the method may include the steps of:

in step 902, the ue requests radio communication resources from the radio resource scheduling device in a specific time period, so as to continuously obtain radio communication resources allocated by the radio resource scheduling device in the specific time period.

In an embodiment, the radio resource scheduling device may reallocate new radio communication resources to the ue each time a request from the ue is received, so as to ensure that the ue always has corresponding radio communication resources.

In an embodiment, the radio resource scheduling device may reset the management scheduling period or the resource holding duration defined by the radio resource management mechanism when receiving the request of the user equipment, without reallocating the radio communication resources, and may ensure that the user equipment is allocated with the radio communication resources.

In an embodiment, the radio resource scheduling device schedules radio communication resources according to a management scheduling period, and the user equipment may continuously send an activation signal to the radio resource scheduling device in the specific time period, so that a scheduling parameter corresponding to the management scheduling period in the specific time period is set to a valid value; and when the scheduling parameter corresponding to the management scheduling period is set to be a valid value, the user equipment requests the wireless communication resource from the wireless resource scheduling equipment in the management scheduling period. In other words, by continuously transmitting the activation signal in the specific time period, the user equipment can determine that the data transmission requirement exists in the specific time period all the time, so that the scheduling parameter can be ensured to be kept set to a valid value in the specific time period, and the user equipment continuously requests the corresponding wireless communication resource from the wireless resource scheduling equipment in the specific time period. The activation signal may refer to the embodiment shown in fig. 2A-2C, and will not be described herein.

In an embodiment, the radio resource scheduling device schedules radio communication resources according to a management scheduling period, and the user equipment may set a scheduling parameter corresponding to the management scheduling period in the specific time period to be a valid value; and when the scheduling parameter corresponding to the management scheduling period is set to be a valid value, the user equipment requests the wireless communication resource from the wireless resource scheduling equipment in the management scheduling period. In other words, the ue does not need to continuously send an activation signal or other signals, but actively keeps the scheduling parameter set to a valid value in the specific time period, so that the ue continuously requests the corresponding radio communication resource from the radio resource scheduling device in the specific time period.

To further describe the delay improvement of the wireless communication process according to the embodiments of the present disclosure, the SR (Scheduling Request, uplink scheduling request) mechanism adopted by the RRC technology is described below with respect to the notification message-based embodiment shown in fig. 9.

Fig. 10 is a schematic diagram of an SR mechanism of an example embodiment. As shown in fig. 10, taking the interaction between the UE and the eNodeB as an example, the interaction procedure may include: the UE monitors whether the UE has an uplink demand or not; when the uplink demand is monitored, the UE initiates a scheduling request to the eNodeB so as to determine whether corresponding wireless communication resources (such as air interface resources, MAC resources and the like) need to be allocated to the UE or not by the eNodeB; then, after the UE obtains the uplink scheduling grant of the eNodeB, the UE may send uplink data to the eNodeB by using the radio communication resource allocated by the eNodeB, so as to meet the uplink requirement described above.

Fig. 11 is a schematic diagram of an SR cycle of an example embodiment. The SR mechanism provides the UE with an opportunity to report its uplink scheduling request to the eNodeB, which reporting opportunity does not exist at any time, and should be in line with the reporting period as shown in fig. 11. The eNodeB divides the corresponding SR resources (SR reporting units) for each UE, UE1, UE2, etc., which may include several subframes numbered 0-9, such as shown in fig. 9, for example, subframes numbered 2 may be divided to UE1 and subframes numbered 5 may be divided to UE2. The SR resources appear according to the time sequence cycle, so that the UE1 can report the uplink scheduling request when the subframe with the number of 2 appears, and the UE2 can report the uplink scheduling request when the subframe with the number of 5 appears; in other words, each UE has a different offset value in the same SR period, and assuming that each SR period starts from reference number 0 and ends from reference number 9, the offset value corresponding to UE1 is 2, i.e., 2 subframes from reference number 0 to 2 subframes, and the offset value corresponding to UE2 is 5, i.e., 5 subframes from reference number 0 to 5 subframes.

Each UE needs to assign its corresponding SR parameter in each SR period, for example, an active value 1 or an inactive value 0, depending on whether the UE currently has a data transmission requirement: the UE will assign the SR parameter to 1 when there is a data transmission demand, and to 0 when there is no data transmission demand. When the UE assigns the SR parameter corresponding to a certain SR period to 1, the UE can report an uplink scheduling request by utilizing the subframe corresponding to the offset value in the SR period; when the UE assigns the SR parameter corresponding to a certain SR period to 0, the UE cannot report the uplink scheduling request in the SR period.

For example, fig. 12 is a schematic diagram of a data transmission procedure based on an SR mechanism according to an exemplary embodiment. As shown in fig. 12, taking a data transmission procedure between UE1 and eNodeB as an example, when UE1 monitors that uplink data 1 is generated, if the SR parameter of UE1 in the current SR period is assigned to 1, UE1 may send an uplink scheduling request to eNodeB through a subframe denoted by 2 to request uplink resources (wireless communication resources used for the uplink procedure) to eNodeB, and send the above uplink data 1 through uplink resources scheduled by eNodeB; accordingly, the eNodeB sends the uplink data 1 to the server, and receives the downlink data returned by the server, so as to return to the UE1.

When UE1 monitors that uplink data 2 is generated, if the interval from the previous data transmission operation is long, the radio communication resources previously allocated to UE1 are released, and a new uplink resource needs to be requested to be allocated to the eNodeB again, so that the uplink data 2 can be transmitted. However, if no other uplink data is generated within a long time before the uplink data 2 is generated, the UE1 may assign its SR parameter corresponding to the current SR period to 0, so that the UE1 cannot send an uplink scheduling request to the eNodeB in the current period, the eNodeB cannot allocate a corresponding uplink resource to the UE1 in the current period, but only can assign the SR parameter corresponding to the next SR period to 1, and wait for the arrival of the subframe labeled 2 in the next SR period, the UE1 can initiate the uplink scheduling request to the eNodeB, and send the uplink data 2 according to the radio communication resource scheduled by the eNodeB, thereby causing a data transmission delay for the uplink data 2.

Fig. 13 is a schematic diagram of a data transmission procedure in the form of notification provided in an exemplary embodiment. As shown in fig. 13, taking still the data transmission between UE1 and eNodeB as an example, assuming that UE1 triggers a continuous upload requirement, i.e. wishes to continuously transmit a plurality of data packets, UE1 may start a timer of a specific duration to ensure that the value of the SR parameter remains at 1 until the timer expires, regardless of whether UE1 has an actual data transmission requirement in the corresponding SR period.

In an embodiment, after starting the timer, UE1 may automatically implement the assignment process for the SR parameter, that is, make the SR parameter be assigned 1; alternatively, UE1 may keep sending an activation signal to the eNodeB after starting the timer, such that the SR parameter is assigned a value of 1 accordingly.

In an embodiment, the timer started by UE1 may be a predefined fixed duration, such as 2s.

In an embodiment, the duration of the timer started by the UE1 may be related to the actual continuous data uploading requirement, for example, a shorter duration may be set when the amount of data to be continuously uploaded is smaller, and a longer duration may be set when the amount of data to be continuously uploaded is larger, so as to meet the actual requirement of the UE1 on data transmission.

Assuming that UE1 sets a specific duration of 2s for the timer and an SR period of 20ms, that is, the timer is running for a maximum of 100 SR periods, UE1 may assign SR parameters in the 100 SR periods to 1, so that UE1 requests uplink resources from eNodeB using subframes numbered 2 in each SR period, and as long as uplink data 1 and uplink data 2 are generated in the 2s, data transmission may be performed by UE using the uplink resources requested by the UE in the corresponding SR period without waiting and delaying as shown in fig. 12 due to the SR resources in the SR period being assigned to 0.

For example, as shown in fig. 13, when UE1 detects that uplink data 2 is generated, it is assumed that the UE1 is at subframe 8 of a certain SR period, and since the SR parameter of the SR period currently in which the UE1 is currently in the running period of the timer started at this time is assigned to 1, the UE1 has actually requested uplink resources from the eNodeB through the subframe labeled 2 in the SR period currently in which the UE1 is currently in place, so that the UE1 can directly use the uplink resources to transmit uplink data 2 to the eNodeB without waiting for the request of uplink resources in the next SR period, thereby significantly optimizing the data transmission delay problem of uplink data 2.

Fig. 14 is a schematic diagram of PING packet testing in a wireless communication network environment in accordance with an exemplary embodiment. As shown in fig. 14, in the same wireless communication network environment (for example, the duration of the DRX deactivation timer is 100ms, the SR period is 20 ms), the same UE generates the activation pulses based on the embodiments shown in fig. 2A-2C with the periods of 40ms, 100ms, 400ms, and 800ms, and performs the corresponding PING (Packet Internet Groper, internet packet explorer) packet test, and performs the PING packet test without the pulse, so that 5 curves shown in fig. 12 can be obtained, respectively.

According to the test results shown in fig. 14, when an activation pulse with a period of 40ms is used, the PING delay is shortest and averages 27.7ms; along with the continuous increase of the period, the corresponding PING time delay is also prolonged; in the absence of pulses, PING delay is maximum, averaging 58.6ms. It can be seen that in the case of using an activation pulse with a period of 40ms, the PING packet delay is only 47% of that in the case of no pulse, so that the delay problem of the UE is greatly improved; even with an activation pulse of 800ms period, the time delay is significantly better than the no pulse condition, as is evident from the graph shown in fig. 14.

Similar to the test case shown in fig. 14, when the embodiments shown in fig. 6-7 and 9 are employed, a significant improvement in latency can be achieved as well, and will not be described in detail.

In summary, according to the above embodiments, in the present disclosure, the UE continuously transmits the activation signal, or the UE transmits the notification message including the holding identifier to the radio resource scheduling device, or the UE continuously requests the radio resource scheduling device for the radio communication resource, which can ensure that the UE maintains the allocated radio communication resource in the process of implementing continuous data transmission, ensure that the UE can implement continuous data transmission, and reduce the data transmission delay.
