Description

Uplink resource allocation method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a terminal, and a network device for allocating uplink resources.

Background

In a Logical Channel priority LCP (LCP) processing procedure of a Long Term Evolution (LTE) system, the processing procedure is performed based on a priority parameter (priority) corresponding to a single Radio Bearer (RB) configured by a network, and a specific execution procedure of the processing procedure may include:

step 1: and performing the first round of resource allocation according to the descending order of priority parameters (priorities) of all the logical channels with tokens. The first round of resource allocation is based on a Prioritized Bit Rate (PBR) of each logical channel. And updating the number of available tokens of each logical channel according to the resource allocation condition.

Step 2: if there are more resources left, then a second round of resource allocation is performed. The second round of resource allocation is to allocate resources to the data except the PBR in descending order of priority parameters (priorities) of all the logical channels with data transmission. Resource allocation until all data of the logical channel with the token is allocated resources or the resources are exhausted.

The services supported by the 5G New air interface (NR) include: enhanced Mobile Broadband (eMBB) service, mtc (massive Machine Type Communications) service, and URLLC (Ultra-Reliable and Low Latency Communications) service.

The delay requirement of URLLC service is particularly high, and the end-to-end delay may be 0.5 ms. However, when the core network configures quality of service (QoS) parameters, since priority of the QoS parameters does not only need to consider delay, the priority may be lower than that of the eMBB service.

At present, in a system with multiple base band parameters (numerology) and/or multiple Transmission Time Intervals (TTIs) coexisting, there is no clear solution on how to guarantee that resources of a service sensitive to priority are preempted by other services, such as resources of a low-priority URLLC service preempted by a high-priority eMBB service or resources of data other than PBR data preempted by a PBR of a high-priority URLLC service of a low-priority eMBB service.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help the full understanding of the embodiments of the present invention. Thus, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention. In addition, the terms "system" and "network" are often used interchangeably herein.

First, related concepts involved herein are presented.

1) Numerology is a generic term for 3GPP RAN1, referred to herein as baseband parameters. The main difference between different numerologies is that the subcarrier spacing supported by different numerologies is different. For example, the subcarrier spacing supported by the 5G NR (New Radio, New air interface) system at least includes: 15KHz, 60KHz, the numerology corresponding to these two different subcarrier spacings is two independent numerologies.

Generally, numerology used by high speed terminals is different from numerology used by low speed terminals; numerology used for high and low frequencies is also different. The use of different numerologies, in addition to being speed and frequency dependent, the industry has also appreciated that numerologies that different services may be used may also be different, such as numerologies used by URLLC and eMBB.

2) TTI is the Transmission Time interval (Transmission Time interval). In a conventional LTE system, the TTI length is 1 ms. Starting from LTE R14, to support latency reduction, different TTI lengths are introduced, such as 1 OFDM symbol length. Different TTI lengths are used in 5G systems and can be applied per numerology, i.e. different numerologies in 5G NR can use different TTI lengths, or the same TTI length, and the TTI lengths used for different terminals at a certain numerology at any one time can be dynamically changed.

The TTI length is selected mainly in relation to the service delay, for example, for URLLC service, because the delay requirement supported by it is relatively high, it is possible to select a TTI length with a shorter length, for example, a TTI length of 1 OFDM symbol.

3)K2

K2 corresponds to an uplink scheduling delay from uplink grant information (UL grant) to a specifically scheduled Physical Uplink Shared Channel (PUSCH) transmission in uplink transmission scheduling, i.e., UL scheduling timing. In NR, the K2 is an indication displayed in each UL grant according to the current conclusion.

4) Quality of service template (QoS profile)

The concept of quality of service templates (QoS profiles) is introduced herein, each QoS template (QoS profile) may correspond to one transmission delay parameter, and the template may include transmission-related parameters corresponding to QoS (such as transmission delay parameters) corresponding to the QoS template, and specifically may be one or more of the following parameters: TTI, numerology, uplink scheduling delay (k2), and monitored resource range of the physical downlink control channel PDCCH (e.g. resource location and pattern of the monitored PDCCH). Here, the uplink grant information may be monitored in the monitored resource range of the PDCCH. By different values of the parameters, a template with specific transmission delay parameters can be defined. The network may pre-configure the correspondence between the LCH and the qos template, and may send the correspondence to the terminal through RRC signaling or DCI. Here, in the above correspondence relationship, one LCH may correspond to at least one qos template, and one qos template may correspond to at least one LCH.

In order to reduce or avoid the problem that transmission resources of a service with a low priority but sensitive to delay are preempted by a service with a high priority, an embodiment of the present invention provides a method for allocating uplink resources, which is applied to a terminal side, as shown in fig. 1, and the method includes:

step 11, receiving a first uplink grant (UL grant) sent by a network.

Step 12, determining a first uplink transmission resource scheduled by the first uplink grant information, and determining a first quality of service template (QoS profile) corresponding to the first uplink grant information, where each QoS template has a corresponding transmission delay parameter (latency).

In an embodiment of the present invention, at least one quality of service template (also referred to herein as OoS profile) is predefined. Each qos template has a corresponding propagation delay parameter (latency), for example, a plurality of non-overlapping propagation delay ranges may be divided according to the propagation delay range, and then a corresponding qos template is defined for each propagation delay range. The quality of service template comprises at least one of the following transmission parameters: a Transmission Time Interval (TTI), a baseband parameter (numerology), an uplink scheduling delay (k2), and a monitored resource range of a physical downlink control channel PDCCH.

Here, determining the first quality of service template (QoS profile) corresponding to the first uplink grant information may be performed in any one of the following manners:

A) and extracting a template index (profile index) for uniquely identifying the first quality of service template from the first uplink authorization information.

Here, the network is required to carry the template index when sending the first uplink grant information.

B) And extracting transmission parameters as the transmission parameters of the first quality of service template according to the first uplink authorization information, the transmission resources of the first uplink authorization information and the first uplink transmission resources.

Here, the corresponding transmission parameters such as TTI/numrole/K2 may be extracted according to modification information carried in the uplink grant information, a time-frequency resource for transmitting the uplink grant information, and a time-frequency resource position corresponding to a PUSCH scheduled by the uplink grant information, and these transmission parameters are used as transmission parameters of the first quality of service template to represent the first quality of service template. For example, when the LCP module of the terminal performs processing, the extracted transmission parameters may be sent to the LCP template for subsequent processing.

C) And extracting transmission parameters as the transmission parameters of the first quality of service template according to the first uplink authorization information, the transmission resources of the first uplink authorization information and the first uplink transmission resources, and determining the template index of the corresponding first quality of service template according to the transmission parameters of the first quality of service template.

Here, similar to the above-mentioned method B, the transmission parameters are extracted, then the qos target is determined, the qos target is matched with the extracted transmission parameters, the matched qos template is used as the first qos template, and the template index (profile index) of the template can be determined. For example, the profile index is sent to the LCP template for subsequent processing.

Step 13, determining a second service quality template corresponding to the logical channel to be transmitted according to a correspondence between a preconfigured Logical Channel (LCH) and a service quality template, and determining whether the first uplink transmission resource can transmit the logical channel to be transmitted according to the first service quality template and the second service quality template.

In step 13, it is determined whether the first uplink transmission resource can transmit the logical channel to be transmitted, so as to find the logical channel to be transmitted, which can be transmitted by the first uplink transmission resource, and further allocate the first uplink transmission resource for the found logical channel to be transmitted. When the uplink transmission resource is specifically allocated, reference may be made to a processing manner of the LCP module in the prior art, which is not described herein again.

As an implementation manner, when a predetermined transmission parameter in a first qos template is less than or equal to the predetermined transmission parameter in a second qos template, it is determined that the first uplink transmission resource can transmit the to-be-transmitted logical channel, otherwise, it is determined that the first uplink transmission resource cannot transmit the to-be-transmitted logical channel.

Here, the predetermined transmission parameter may be any one of a Transmission Time Interval (TTI), a baseband parameter (numerology), an uplink scheduling delay (k2), and a monitored resource range of a physical downlink control channel PDCCH. For baseband parameters (numerology), values of subcarrier spacing may be employed for comparison and determination.

As another implementation manner, when a first time delay calculated based on a transmission parameter in a first quality of service template is less than or equal to a second time delay calculated based on a transmission parameter in a second quality of service template, it is determined that the first uplink transmission resource can transmit the logical channel to be transmitted, and otherwise, it is determined that the first uplink transmission resource cannot transmit the logical channel to be transmitted.

Here, the first time delay is determined in any one of the following ways:

for example, the first delay is determined according to an uplink scheduling delay K2. For example, K2 is directly used as the first delay, or a sum of K2 and a preset first value is used as the first delay.

For another example, the first delay is calculated according to the uplink scheduling delay K2 and the transmission duration of the Physical Uplink Shared Channel (PUSCH) scheduled by the first uplink grant information. For example, the sum of K2 and the transmission duration of the PUSCH is used as the first delay.

For another example, the first time delay is determined according to a transmission duration of a Physical Uplink Shared Channel (PUSCH) scheduled by the first uplink grant information. For example, the transmission duration of the PUSCH is used as the first delay. Or taking the sum of the transmission duration of the PUSCH and a preset second value as the first time delay.

As another implementation manner, when the first qos template and the second qos template are the same qos template, it is determined that the first uplink transmission resource can transmit the logical channel to be transmitted, and otherwise, it is determined that the first uplink transmission resource cannot transmit the logical channel to be transmitted.

Through the above steps, in the embodiment of the present invention, by configuring the corresponding relationship between the logical channel and the quality of service template in advance, when the terminal performs logical channel transmission, the transmission resource that can be used by the logical channel to be transmitted is determined according to the quality of service template corresponding to the scheduling resource and the second quality of service template corresponding to the logical channel to be transmitted, so that the problem that the transmission resource of a service that is low in priority but sensitive to delay is preempted by a service with high priority can be reduced or avoided.

Before step 11, the terminal may further receive configuration information sent by the network for configuring a correspondence between a Logical Channel (LCH) and a quality of service template, and specifically, may receive the configuration information through RRC signaling or DCI.

Preferably, in the embodiment of the present invention, when the terminal receives multiple uplink grant messages simultaneously, the terminal may receive the uplink grant messages in sequence according to the sequence from short to long of the time domain length of the monitored resource range of the physical downlink control channel PDCCH of each uplink grant message, so as to preferentially process the service with high delay requirement according to the delay requirement.

Preferably, in the embodiment of the present invention, when the terminal receives multiple uplink grant information simultaneously, the terminal (specifically, the LCP module of the terminal) may sequentially determine whether the uplink transmission resource scheduled by each uplink grant information can transmit the to-be-transmitted logical channel of the terminal according to a pre-configured processing sequence of each uplink grant information;

or, sequentially determining whether uplink transmission resources scheduled by each uplink grant information can transmit a logical channel to be transmitted of the terminal according to a sequence of small arrival of predetermined transmission parameters (such as TTI, numerical index/subcarrier spacing, or value of K2) of a qos template corresponding to each uplink grant information;

or, sequentially determining whether the uplink transmission resource scheduled by each uplink authorization information can transmit the logical channel to be transmitted of the terminal according to the sequence from small to large of the second time delay corresponding to each uplink authorization information, wherein the second time delay corresponding to each uplink authorization information is calculated according to the transmission parameter of the quality of service template corresponding to the uplink authorization information.

Here, the second time delay is determined in any one of the following ways:

for example, the second delay is determined according to the uplink scheduling delay K2. For example, K2 is directly used as the second delay, or a sum of K2 and a preset third value is used as the second delay.

For another example, the second delay is calculated according to the uplink scheduling delay K2 and the transmission duration of the Physical Uplink Shared Channel (PUSCH) scheduled by the uplink grant information. For example, the sum of K2 and the transmission duration of the PUSCH is used as the second delay.

For another example, the second delay is determined according to a transmission duration of a Physical Uplink Shared Channel (PUSCH) scheduled by uplink grant information. For example, the transmission duration of the PUSCH is used as the second delay. Or taking the sum of the transmission duration of the PUSCH and a preset fourth value as the second time delay.

Preferably, in the embodiment of the present invention, when the first uplink transmission resource can transmit a plurality of logical channels to be transmitted, the terminal may sequentially transmit each logical channel to be transmitted according to a descending order of transmission delay parameters of the quality of service template corresponding to the logical channel to be transmitted; or, sequentially transmitting each logical channel to be transmitted according to a descending order of predetermined transmission parameters (such as TTI, numerical index/subcarrier spacing, or K2 value) of a service quality template corresponding to the logical channel to be transmitted; or, sequentially transmitting each logic channel to be transmitted according to a random sequence.

The method flow of the embodiment of the present invention at the terminal side is described above.

The method flow of the embodiment of the present invention at the network side is further described below. Referring to fig. 2, when the method for allocating uplink resources provided in the embodiment of the present invention is applied to a network side, the method includes:

step 21, sending configuration information of the corresponding relation between the Logical Channel (LCH) and the quality of service template to the terminal.

Here, the network may transmit the above configuration information to the terminal through RRC signaling or DCI.

And step 22, sending the first uplink authorization information to the terminal.

Here, as an implementation manner, the first authorization information may carry a template index of a first quality of service template corresponding to the first uplink authorization information.

Through the steps, the network configures the corresponding relation between the Logical Channel (LCH) and the service quality template for the terminal, so that the terminal can allocate by combining the corresponding relation when allocating uplink transmission resources subsequently.

As can be seen from the above description, in the embodiment of the present invention, uplink resource allocation is performed based on physical layer transmission characteristics, and in the uplink resource allocation process at the terminal side, the terminal performs a process of selecting the priority of an uplink channel according to a quality of service template (QoS profile) corresponding to each Logical Channel (LCH), so that the problem that transmission resources of a service that is low in priority but sensitive to delay are preempted by a service with a high priority can be reduced or avoided.

Fig. 3 further shows an example of the configuration of the QoS profiles corresponding to LCHs with different QoS requirements, which include different PDCCH monitoring times in the embodiment of the present invention.

Fig. 3 shows 3 LCHs, which are LCH 1-LCH 3, respectively having different transmission QoS, and the respective corresponding PDCCH monitoring resource ranges are as the monitoring ranges shown in fig. 3, it can be seen that the respective monitoring ranges are different, so the parameters of the monitored resource range of the PDCCH can be configured in the QoS profile, for example, the two quality of service templates tr.profile1 and tr.profile1 respectively give specific resource ranges for PDCCH monitoring.

Fig. 4 further shows that when multiple UL grants are received simultaneously in the embodiment of the present invention, different delay (latency) information is calculated according to the configuration in the QoS profile. Here, the latency is K2+ PUSCH duration, and the specific locations where the corresponding URLCC service and EMBB service are transmitted are selected based on the delay information, where it is assumed that URLLC and EMBB are different logical channel groups (local channel groups).

In fig. 4, the terminal receives 4 UL grants at the same time, where the latency information (in this example, K2+ PUSCH transmission duration) calculated by the content corresponding to grant1/grant2 is less than the corresponding latency index in the QoS profile of the URLLC service LCH, and the LCP process of the terminal puts the LCH required by the URLLC QoS in the transmission resources scheduled by the two UL grants for transmission; similarly, the transmission of the EMBB traffic is placed in the transmission resource scheduled by the UL grant3/4 according to the configuration for transmission.

Here, if the transmission of the eMBB is allowed to be transmitted in the transmission resource scheduled by the UL grant1/2/3/4, since the latency of the ULgrant1/2 preferentially transmits the URLLC service requires strict traffic, the eMBB service can be transmitted only in the UL grant 3/4.

Based on the method provided by the above embodiment, an embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored, where the computer program, when executed by a processor, implements the following steps: receiving first uplink grant information (UL grant) sent by a network; determining a first uplink transmission resource scheduled by first uplink authorization information, and determining a first quality of service (QoS) template corresponding to the first uplink authorization information, wherein each QoS template has a corresponding transmission delay parameter (latency); determining a second service quality template corresponding to a logic channel to be transmitted according to a corresponding relation between a Logic Channel (LCH) configured in advance and a service quality template, and determining whether the first uplink transmission resource can transmit the logic channel to be transmitted according to the first service quality template and the second service quality template.

Based on the method provided by the above embodiment, another computer-readable storage medium is further provided, on which a computer program is stored, and when the computer program is executed by a processor, the method includes the following steps: sending configuration information of a corresponding relation between a Logic Channel (LCH) and a service quality template to a terminal; and sending the first uplink authorization information to the terminal.

The non-volatile Memory may be a Read-Only Memory (ROM), a Programmable ROM (PROM), an Erasable PROM (EPROM), an Electrically Erasable PROM (EEPROM), or a flash Memory.
