Description

Uplink resource request method and device

Technical field

The present invention relates to the field of communications technologies, and in particular, to an uplink resource request method and apparatus.

Background technique

The emergence of a new generation of new Internet applications has placed higher demands on wireless communication technologies, driving wireless communication technologies to evolve to meet the needs of applications. At present, cellular mobile communication technology is in the evolution stage of next-generation technology. How to better design uplink transmission to meet the needs of the system in a new generation of mobile communication systems is an important issue.

In NR (New Radio), flexible configuration of multiple service types needs to be supported. Different types of services have different requirements for wireless communication technologies. For example, the main requirements of the enhanced mobile broadband (eMBB) service type are focused on large bandwidth and high rate, and high reliability communication (URLLC, Ultra Reliable Low Latency). Communication) The main requirements of the service type focus on high reliability and low latency. The main requirements of the MMTC (massive machine type of communication) service type focus on the large number of connections. In order to support multiple services at the same time, a plurality of logical links (LCH, Logical Channel) are defined in the Medium Access Control (MAC) layer to correspond to data of different QoS requirements. Different from LTE, in order to support services with multiple different QoS requirements in the NR, the same user equipment (UE) can be configured with multiple different SR configurations, each SR configuration corresponding to one or more LCHs.

The Uplink Control Information (UCI) includes a Hybrid Automatic Repeat ReQuest (HARQ) indication, a Scheduling Request (SR), and a Channel State Information (CSI). It is used by the user equipment to apply for uplink resource scheduling to the base station side. The uplink control information may be transmitted through a physical uplink control channel (PUCCH, Physical Uplink Control CHannel). In addition, when the HARQ indication and the transmission of the CSI on the PUCCH and the uplink data transmission of the Physical Uplink Shared Channel (PUSCH) coincide in the time domain, for example, when the start symbol (symbol) position is the same, the user The device can discard the transmission of the PUCCH, and transmit the UCI information of the HARQ indication and the CSI through the PUSCH and the uplink data, so as to ensure the single carrier characteristic of the uplink transmission and obtain a better peak-to-average power ratio (PAPR, Peak to Average). Power Ratio) and lower maximum power reduction (MPRMaximum Power Reduction).

In the related art, when the user equipment has new uplink data to be sent, a buffer status report (BSR, Buffer Status Report) transmission is triggered. When the user equipment has an activated BSR but does not have a corresponding uplink resource to transmit, the SR transmission is triggered. In the existing NR scheme, if the user equipment has a PUSCH transmission at the same time when the SR is activated, the MAC layer selects an SR transmission resource that does not coincide with the PUSCH uplink data transmission in the time domain, and commands the physical layer to perform SR transmission. From the perspective of the physical layer, the PUCCH transmission of the SR and the uplink data PUSCH transmission do not coincide in the time domain.

detailed description

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. The following description refers to the same or similar elements in the different figures unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with aspects of the invention as detailed in the appended claims.

In the related art, when the user equipment has new uplink data to be sent, the buffer status report (BSR, Buffer Status Report) transmission is triggered; when the user equipment has the activated BSR but no corresponding uplink resource is sent, Will trigger SR transmission. In the existing NR scheme, if the user equipment has a PUSCH transmission at the same time when the SR is activated, the MAC layer selects an SR transmission resource that does not coincide with the PUSCH uplink data transmission in the time domain, and commands the physical layer to perform SR transmission. From the perspective of the physical layer, the PUCCH transmission of the SR and the uplink data PUSCH transmission do not coincide in the time domain. In practice, the same user equipment may perform uplink transmission of the URLLC service and the eMBB service at the same time. In order to guarantee low latency (such as 1ms) and high reliability of URLLC services, URLLC services are usually set to a higher QoS priority. For eMBB data, in order to ensure a high data rate and transmission efficiency, a long transmission time such as 1 slot (14 symbols, 1 ms when the 15 KHz carrier interval is used) is usually used.

However, when the new data of the high-priority URLLC service arrives, if the user equipment has the PUSCH uplink data transmission of the eMBB service at the same time, the user equipment needs to wait for the PUSCH uplink data transmission of the eMBB to end, and then the SR can be sent. As a result, the transmission delay of the URLLC service cannot be guaranteed, and the quality of service (QoS) requirements cannot be guaranteed, and the user experience is poor.

In order to solve the above problem, the embodiment of the present invention provides an uplink resource request method, where the method includes: when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmits the resource and the user When the uplink data transmission or the user measurement interval conflicts, the random access request is sent to the special cell; and the triggered SR is cancelled. In the uplink resource requesting method provided by the embodiment of the present invention, when the SR transmission conflicts with the uplink data transmission, the UE initiates a random access procedure in the special cell, so as to quickly apply for the uplink resource of the service that triggers the SR, thereby reducing the new service transmission. The transmission delay of the data can avoid the problem of low latency requirements of the unguaranteed service caused by the need to wait for the uplink data transmission to be sent in the related art, and can guarantee the service QoS and improve the user experience.

Based on the above analysis, the following specific embodiments are proposed.

FIG. 1 is a flowchart of an uplink resource request method according to an exemplary embodiment; an execution body of the method may be a UE, such as a mobile phone, a tablet, or a wearable device (such as a wristband). As shown in FIG. 1, the method includes the following steps 101-102:

In step 101, when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval, the random access request is sent to the special cell. .

In step 102, the triggered SR is cancelled.

For example, when the uplink data of the second service arrives and there is no uplink resource for sending the uplink data of the second service, the SR of the UE is triggered; however, when the SR of the UE is triggered, if the UE is performing the first service For the uplink data transmission, in the case of adopting the related technology, the UE needs to wait for the uplink data transmission of the first service to end before transmitting the SR, which results in the transmission delay of the second service cannot be guaranteed. In order to solve the problem, in the present invention, when the SR of the UE is triggered, when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource and the user uplink data transmission or When the user measurement interval conflicts, the UE sends a random access request to the special cell, and the base station allocates the uplink resource for transmitting the new data of the second service to the UE, and cancels the triggered SR, so as to implement the fast application for triggering the second service of the SR. Uplink resources, thereby reducing the transmission delay of the new data of the second service.

For example, when there is a valid uplink control channel transmission resource configured for the triggered scheduling request SR of the user equipment UE, and the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval, The implementation manner of sending a random access request to a special cell may include at least one of the following modes or combinations:

When the SR of the UE is triggered, when there is a valid uplink control channel transmission resource configured for the triggered scheduling request SR of the user equipment UE, the latest N SRs on the uplink control channel transmission resource are determined. Whether the transmission opportunity is coincident with the user uplink data transmission, and/or the user measurement interval in the time domain; when the latest N SR transmission opportunities on the uplink control channel transmission resource are all uplink data transmission with the UE, and / or the user measurement interval sends a random access request to the special cell when there is a coincidence in the time domain. Where N is a positive integer.

It should be noted that determining whether the most recent N SR transmission opportunities on the uplink control channel transmission resource overlap with the user uplink data transmission and/or the user measurement interval in the time domain is equivalent to three parallel determination conditions. : a) determining whether the most recent N SR transmission opportunities on the uplink control channel transmission resource are coincident with the user uplink data transmission in the time domain; or, b) determining the latest N of the uplink control channel transmission resources Whether the SR transmission opportunities are coincident with the user uplink data transmission and the user measurement interval in the time domain; or, c) determining whether the latest N SR transmission opportunities on the uplink control channel transmission resource are both in the time domain with the user measurement interval There is a coincidence on it. As long as any one of the above conditions a), b), and c) is satisfied, the UE is triggered to transmit a random access request to the special cell.

For example, when the SR of the UE is triggered, if there is a valid PUCCH resource configured for the SR, and the most recent N consecutive SR transmission opportunities on the valid PUCCH resource are both uplink UL-SCH transmission, and/or The user measurement interval has coincidence in the time domain, and the UE may initiate a random access procedure on the special cell and cancel the triggered SR.

Embodiment 2: The base station sends the first control signaling to the UE in advance, where the first control signaling is used to indicate that the UE is in conflict with the user uplink data transmission or the user measurement interval when the uplink control channel transmission resource conflicts with the user a triggering condition for the special cell to send a random access request; after receiving the first control signaling, the UE obtains that the UE sends the uplink control channel transmission resource to the special cell when the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval conflicts The trigger condition for the random access request. Determining whether the trigger condition is satisfied when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource conflicts with a user uplink data transmission or a user measurement interval; When the trigger condition is met, a random access request is sent to the special cell.

For example, the first control signaling may be RRC signaling, MAC signaling, or physical layer signaling. For example, the base station configures the UE in advance through RRC signaling, and indicates the UE behavior when the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval. The RRC configuration may be based on a certain UE group, may be based on a specific UE, or may be based on a specific uplink data logical link or logical link group of a specific UE. The UE decides whether to initiate a random access procedure on the special cell according to the RRC configuration. For example, the base station may also send, by using RRC signaling, the switch configuration of whether the random access procedure is initiated on the spcell in the case of coincidence in the time domain. If the switch is on, the uplink control channel transmits resources and the user uplink data transmission or When the user measurement interval conflicts, the random access procedure is initiated on the special cell, otherwise the random access procedure is not initiated.

Embodiment 3: The base station sends a second control signaling to the UE in advance, where the second control signaling is used to indicate that the UE is in conflict with the uplink data transmission of the uplink control channel or the user measurement interval The indication information of the random access request is sent by the special cell; after receiving the second control signaling, the UE is configured to instruct the UE to send the special uplink control channel transmission resource to the user uplink data transmission or the user measurement interval conflict to the special The cell sends indication information of the random access request. When there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval, sending to the special cell according to the indication information Random access request. For example, the second control signaling may be RRC signaling, MAC signaling, or physical layer signaling.

Embodiment 4: When the SR of the UE is triggered, when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource and user uplink data transmission or user measurement Obtaining, in an interval conflict, a first QoS priority of the service that triggers the SR, and a second QoS priority of the user uplink data that conflicts with the uplink control channel transmission resource; when the first QoS priority is higher than the foregoing When the second QoS priority is used, a random access request is sent to the special cell.

For example, the UE determines whether to initiate a random access procedure on a special cell according to at least one of the following information or combination: information 1, QoS priority of the logical link of the second service corresponding to the SR; information 2, uplink UL- SCH corresponding QoS priority; information 3, measurement interval configuration parameters. For example, if the QoS priority corresponding to the UL-SCH in which the most recent SR transmission opportunities occur in the time domain (ie, the highest QoS priority in the corresponding logical link) is lower than the priority of the logical link corresponding to the SR. And there is no measurement interval that coincides with the time domain of the nearest N SR transmission opportunities, and the UE chooses to initiate a random access procedure on the special cell.

For example, when the uplink data transmission of the user that conflicts with the uplink control channel transmission resource is two or more, the second QoS priority is two or more user uplinks that conflict with the uplink control channel transmission resource. The maximum value of QoS priority in data transmission.

Embodiment 5: When the SR of the UE is triggered, when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource and the user uplink data transmission or user measurement When the interval conflicts, it is determined that the random access request is sent to the special cell according to the configuration information of the uplink control channel transmission resource and the configuration information of the random access resource on the special cell.

For example, when the next transmission opportunity of the random access resource on the special cell is earlier than the Mth nearest SR transmission opportunity on the uplink control channel transmission resource, it is determined to send a random access request to the special cell.

For example, the UE receives the random access response sent by the base station corresponding to the special cell, and acquires scheduling information of the uplink resource allocated by the base station for transmitting the new data of the second service, and the uplink allocated by the UE according to the scheduling information. The new transmission data of the second service is sent on the resource.

According to the technical solution provided by the embodiment of the present invention, when the SR transmission conflicts with the uplink data transmission, the UE initiates a random access procedure in the special cell to implement the uplink resource of the service that triggers the SR, so as to ensure the new data transmission of the service. The transmission delay requirement can avoid the problem of low latency requirements of the unguaranteed service caused by the need to wait for the uplink data transmission to end before the uplink data transmission ends, and can guarantee the QoS of the service, thus improving the user experience.

FIG. 2 is a flowchart of an uplink resource requesting method according to an exemplary embodiment. As shown in FIG. 2, the method is implemented by a UE. On the basis of the embodiment shown in FIG. The request method can include the following steps 201-204:

In step 201, when the SR of the UE is triggered, it is determined whether there is a valid uplink control channel transmission resource configured for the triggered SR of the UE; if yes, go to step 202; otherwise, the process ends.

In step 202, when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, it is determined whether the most recent N SR transmission opportunities on the uplink control channel transmission resource are all uplink data transmission with the user, and/or The user measurement interval has a coincidence in the time domain; when the latest N SR transmission opportunities on the uplink control channel transmission resource are coincident with the user uplink data transmission, and/or the user measurement interval in the time domain, go to step 203; When the latest N SR transmission opportunities on the uplink control channel transmission resource are not all coincident with the user uplink data transmission, and/or the user measurement interval overlaps in the time domain, go to step 204.

In step 203, a random access request is sent to the special cell, and the triggered SR is cancelled.

In step 204, the SR is transmitted after the end of the user uplink data transmission process.

For example, the UE sends an SR after the end of the user uplink data transmission process; after receiving the SR, the base station allocates an uplink resource for the new transmission data of the service that triggers the SR, and sends a scheduling of the uplink resource for transmitting the service new transmission data to the UE. The UE receives the scheduling information of the uplink resource used by the base station to transmit the newly transmitted data of the service, and sends the service new transmission data on the uplink resource used for transmitting the newly transmitted data of the service.

The technical solution provided by the embodiment of the present invention determines whether the latest N SR transmission opportunities on the uplink control channel transmission resource overlap with the user uplink data transmission and/or the user measurement interval in the time domain. Determining the manner in which the UE sends an uplink resource request to the base station. When the number of SR transmission opportunities that conflict with the uplink data transmission reaches a preset number of N, the UE initiates a random access procedure in the special cell to quickly apply for the SR-triggered service. The uplink resource guarantees the transmission delay of the newly transmitted data of the service.

The trigger condition of the request.

In step 302, when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval, it is determined whether the trigger condition is satisfied; when triggered When the condition is satisfied, go to step 303; when the trigger condition is not satisfied, go to step 304.

In step 303, a random access request is sent to the special cell.

In step 304, the SR is sent after the end of the user uplink data transmission process.

For example, the second control signaling sent by the base station is received, where the second control signaling is used to indicate that the UE sends the uplink control channel transmission resource to the user uplink data transmission or the user measurement interval conflicts to the special cell. And the indication information of the random access request is sent; when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval, And transmitting a random access request to the special cell according to the indication information.

In the technical solution provided by the embodiment of the present invention, the base station configures the UE by using the first control signaling, and indicates the user behavior of the UE when the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval, and the UE determines according to the configuration information. Whether the random access procedure is initiated on the special cell, and the random access procedure is initiated in the special cell, the UE can quickly apply for the uplink resource of the service that triggers the SR, and ensure the transmission delay of the newly transmitted data of the service.

FIG. 4 is a flowchart of an uplink resource requesting method according to an exemplary embodiment. As shown in FIG. 4, the method is implemented by a UE. On the basis of the embodiment shown in FIG. 1, the uplink resource involved in the present invention is shown. The request method can include the following steps 401-404:

In step 401, when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval, the triggering SR is acquired. a first QoS priority of the service, and a second QoS priority of the user uplink data that conflicts with the uplink control channel transmission resource.

In step 402, it is determined whether the first QoS priority is higher than the second QoS priority; when the first QoS priority is higher than the second QoS priority, go to step 403; when the first QoS priority If it is not higher than the second QoS priority, go to step 404.

In step 403, a random access request is sent to the special cell.

In step 404, the SR is sent after the end of the user uplink data transmission process.

According to the technical solution provided by the embodiment of the present invention, when comparing the first QoS priority of the service that triggers the SR and the second QoS priority of the user uplink data that conflicts with the uplink control channel transmission resource, when the first QoS is used When the priority is higher than the second QoS priority, the UE initiates a random access procedure in the special cell, so that the UE can quickly apply for the uplink resource of the service that triggers the SR, and ensure the high priority of the service that triggers the SR.

In step 502, when there is a valid uplink control channel transmission resource configured for the triggered SR of the UE, and the uplink control channel transmission resource conflicts with the user uplink data transmission or the user measurement interval, determining random access on the special cell Whether the next transmission opportunity of the resource is earlier than the nearest Mth SR transmission opportunity on the uplink control channel transmission resource; when the next transmission opportunity of the random access resource on the special cell is earlier than the latest transmission resource on the uplink control channel M SR transmission opportunities, go to step 503; when the next transmission opportunity of the random access resource on the special cell is not earlier than the latest M transmission opportunity on the uplink control channel transmission resource, go to step 504 .

In step 503, a random access request is sent to the special cell.

In step 504, the SR is sent after the end of the user uplink data transmission process.

According to the technical solution provided by the embodiment of the present invention, the next transmission opportunity of the random access resource on the special cell is compared by comparing the configuration information of the uplink control channel transmission resource of the SR and the configuration information of the random access resource on the special cell.
