Description

Scheduling request processing method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a Scheduling Request (sr) processing method and apparatus.

Background

1) Introduction of LTE (Long Term Evolution) BSR (Buffer state report) mechanism

The LTE system is a scheduling-based system, in which a base station allocates time-frequency resources required for data transmission to a terminal device, and the terminal device receives downlink data or transmits uplink data according to a scheduling command from the base station. Uplink data transmission is scheduled by the base station, and the base station scheduler determines an uplink resource allocation and then notifies the terminal through a UL grant (uplink scheduling grant). The base station scheduler allocates uplink resources according to the amount of uplink data to be transmitted by the terminal, i.e. the buffer status of the terminal. The buffer is cached at the terminal side, and the base station needs to perform BSR to the base station in order to acquire the information. The BSR classification and triggering mechanism in LTE Rel-11 and previous releases is as follows:

regular bsr (regular bsr):

(1) triggering when data with higher priority than the data in the current buffer arrives or data arrives in the originally empty buffer;

(2) the retxBSR-Timer times out and triggers when there is data in the buffer.

Periodic bsr (periodic bsr):

the period BSR is triggered when the period BSR-Timer times out.

Piggybacking (Padding BSR):

if the UE has available resources (Padding) in addition to data to be transmitted when organizing a MAC (Media Access Control) PDU (Protocol data unit), the Padding BSR may be triggered.

2) LTE SR mechanism introduction

When the terminal has a Regular BSR trigger (SR masking is not configured for the logical channel triggering the Regular BSR), but the terminal does not have a UL grant, the SR will be triggered.

After the SR is triggered, there are two ways to send the SR, namely: the SR (D-SR) is transmitted through a dedicated scheduling request resource and the SR (RA-SR) is performed through a random access procedure.

Wherein, the special SR (D-SR): the D-SR is allocated by RRC (Radio Resource Control) and is carried by PUCCH (Physical Uplink Control CHannel).

Random access SR (RA-SR): the SR is transmitted using a random access procedure.

The basic principle of SR transmission is: RA-SR is not used as long as D-SR resources are available. The RA-SR will only be used if there is no D-SR resource configuration.

3)5G (short for fifth generation mobile communication technology) new air interface

The physical layer of the NR (New Radio, New air interface) system supports multiple numerology/TTI. The Numerology and TTI concepts are as follows:

numerology is a generic term for 3GPP RAN1 and may be translated into 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 system includes at least: 15KHz, 60KHz, the numerology corresponding to these two different subcarrier spacings is two independent numerologies. Generally, numerology used by a terminal moving at a high speed is different from numerology used by a terminal moving at a low speed; numerology used for high and low frequencies is also different. The use of different numerologies is in addition to the Mobile speed and frequency dependence, an understanding in the industry that numerologies that can be used for different services may also be different, such as numerologies used by URLLC (Ultra Reliable & Low Latency Communication, Low Latency, high reliability Communication) and eMBB (enhanced Mobile Broadband).

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 (orthogonal frequency Division Multiplexing) 0020 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.

For the NR system, numerology and/or TTI corresponding to one bearer/logical channel is configured by the network, for example, the network may configure numerology and/or TTI corresponding to the bearer/logical channel through RRC signaling when the bearer/logical channel is established, and may modify numerology and/or TTI corresponding to one bearer/logical channel through an RRC reconfiguration procedure.

However, for 5G and beyond systems, how the base station performs scheduling has not been concluded at present.

Referring to fig. 2, a flow of a scheduling request processing method is shown, where an execution subject of the method may be a network side device, such as a base station (gNB), and the specific steps are as follows:

step 201, a network side device receives an SR reported by a terminal, where the SR carries specific indication information or a combination of the specific indication information;

For the above b) and c), the scheduling priority may be divided into two levels or more than two levels, wherein the scheduling priorities of the two levels are divided according to a priority scheduling level and a common scheduling level; the scheduling priorities of the two or more levels need to define a priority number, for example, the priority number may be 1,2,3, etc., but is not limited thereto.

In this embodiment, optionally before step 201, the method further includes:

information of a set of configured SR resources, and a mapping relation of the set of SR resources and specific indication information or a combination of specific indication information, or

In this embodiment, optionally, the information related to the scheduling priority includes, but is not limited to, one or more of the following:

the related information of the scheduling priority among different terminals;

relevant information of scheduling priorities corresponding to different bearer QoS (quality of service);

In this embodiment, the network side device may identify, from the SR sent by the terminal, the specific indication information or the combination of the specific indication information for assisting the network side device in scheduling, so that the network side device can obtain scheduling-assisted related information according to the SR, thereby better performing network side scheduling and improving scheduling performance.

In this embodiment, only one set of SR resources is used to carry the specific indication information or the combination of the specific indication information. Referring to fig. 3, a flow of a scheduling request processing method is shown, and the specific steps are as follows:

step 301, the network side device determines configuration information.

The configuration information includes time, frequency and/or spatial resource configuration information used by the set of SR resources. In addition, according to different specific indication information carried by the SR, other configuration information needs to be determined. The method comprises the following specific steps:

if the SR needs to carry the scheduling priority between the terminals, if the scheduling priority needs to be configured by the network side, the network side device also needs to configure the scheduling priority between different terminals through signaling;

if the SR carries scheduling priority information corresponding to a bearer with the highest scheduling priority of an available data, if the priority needs to be configured by the network side, the network side device also needs to configure scheduling priorities corresponding to different bearers QoS (Quality of Service) through signaling, or the network configures scheduling priorities corresponding to each bearer of the terminal through signaling.

Step 302, the network side device sends configuration information to the terminal.

The different configuration information can be transmitted by using the same or different signaling, and the used signaling formats can also be different. For example, the time, frequency domain and/or space domain Resource configuration information used by the SR may be configured through RRC (Radio Resource Control) signaling; scheduling priority information between different terminals is configured using MAC (Media Access Control) signaling.

Step 303: and judging whether the SR is triggered.

For example, the SR triggering condition may be that a regular BSR triggers, but no UL grant triggers an SR. It should be noted that, in the present embodiment, the specific SR triggering condition is not limited, and other SR triggering conditions may be adopted, and will not be repeated here.

Step 304, the terminal determines the specific indication information or the combination of the specific indication information carried by the SR, and the resource used by the SR corresponding to the specific indication information or the combination of the specific indication information.

The specific indication information may include, but is not limited to, one or a combination of the following:

a) downlink beam (beam) identification information;

b) first scheduling priority information of a terminal;

the first scheduling priority information may indicate a scheduling priority between terminals, or may indicate a scheduling priority determined according to a service of a terminal for one terminal.

c) The terminal has available data and second scheduling priority information corresponding to the bearer with the highest scheduling priority;

the second scheduling priority information may indicate the scheduling priority between different bearers of different terminals, or may indicate the scheduling priority determined according to the terminal service for one terminal;

for b) and c), the scheduling priority may be network configured if it is a scheduling priority between terminals or between different bearers of a terminal, or may be terminal-discretionary if it is a scheduling priority determined according to the terminal traffic.

For b) and c), the scheduling priority may be divided into two levels or more. If divided into two levels, the scheduling priority may include: a priority scheduling level and a normal scheduling level. If the scheduling priority is divided into multiple levels, the scheduling priority of the two or more levels needs to define a priority sequence number, where the priority sequence number may be 1,2,3, and the like, such as scheduling priority 1, scheduling priority 2, and scheduling priority 3, although it should be noted that the specific representation form of the scheduling priority is not limited in this embodiment.

In addition, the terminal determines time, frequency domain and/or space domain resource configuration information used by the SR according to the configuration information of the network side equipment.

Step 305, the terminal sends the SR to the network side device.

And the terminal sends the SR to the network equipment according to the SR resource determined in the step 304, wherein the SR carries specific indication information.

If the network side only configures a set of SR resources, the specific indication information is carried by one SR, for example, a new code or sequence is designed for the SR so that it can carry more bits, and different bits correspond to different specific indication information.

Step 306, the network side device obtains the specific indication information carried in the terminal SR.

a) If the specific indication information is downlink beam identification information, the network side device may determine, based on the specific indication information, that downlink beam is used for downlink scheduling transmission;

b) if the specific indication information is first scheduling priority information between the terminals, the network side device may determine a scheduling priority order between different terminals based on the specific indication information;

c) if the specific indication information is second scheduling priority information corresponding to a bearer which has available data and has the highest scheduling priority, the network side device may determine the scheduling priority order among the terminals based on the specific indication information.

Step 307, the network side device performs scheduling based on the specific indication information or the combination of the specific indication information carried in the SR.

Example four

In this embodiment, multiple sets of SR resources, different sets of SR resources correspond to different specific indication information or combinations of specific indication information. Referring to fig. 3, a flow of a scheduling request processing method is shown, and specific steps are as follows;

step 301, the network side device determines configuration information;

the configuration information includes time, frequency domain and/or spatial domain resource configuration information used by each set of SRs. Meanwhile, the configuration information needs to carry the mapping relationship between each set of SR resources and specific indication information or a combination of specific indication information.

For example, the first set of SR configurations corresponds to beam ID1 (beam ID 1); the second set of SR configurations corresponds to beam ID 2.

Or

The first set of SR configuration information corresponds to beam ID1 and scheduling priority 1 between UEs (terminals); the second set of SR configuration information corresponds to beam ID 2 and scheduling priority 2 between UEs.

In addition, according to different specific indication information or combinations of specific indication information carried by the SR, other configuration information needs to be determined. The method comprises the following specific steps:

a) if the SR needs to carry first scheduling priority information between terminals, if the priority needs to be configured by the network side, the network side device also needs to configure scheduling priorities between different terminals through signaling;

b) if the SR carrying terminal has an available data and the second scheduling priority information corresponding to the bearer with the highest scheduling priority, if the priority needs to be configured by the network side, the network side device also needs to configure the scheduling priorities corresponding to different bearer QoS through signaling, or the network configures the scheduling priority corresponding to each bearer of the terminal through signaling.

The different configuration information can be transmitted by using the same or different signaling, and the used signaling formats can also be different. For example, the time, frequency domain and/or space domain resource configuration information used by each group of SRs and the mapping relationship between each group of SR resources and the specific indication information or the combination of the specific indication information may be configured through RRC signaling; and configuring scheduling priority information between different terminals by using MAC signaling.

And step 303, judging whether the SR is triggered.

For example, the SR triggering condition is that a regular BSR triggers, but no UL grant triggers an SR. It should be noted that, in the present embodiment, the specific SR triggering condition is not limited, and other SR triggering conditions may be adopted, and will not be repeated here. Step 304, the terminal determines the specific indication information or the combination of the specific indication information carried by the SR, and the resource used by the SR corresponding to the combination of the specific indication information or the specific indication information

a) identifying information of the downlink beam;

b) first scheduling priority information of a terminal;

For b) and c), the scheduling priority may be divided into two levels or more. If divided into two levels, the scheduling priority may include: a priority scheduling level and a normal scheduling level. If the scheduling priority is divided into multiple levels, the scheduling priorities of more than two levels need to define a priority sequence number, where the priority sequence number may be 1,2, or 3, such as scheduling priority 1, scheduling priority 2, and scheduling priority 3, although it should be noted that the specific representation form of the scheduling priority is not limited in this embodiment.

In this step, the terminal determines which set of SR resources needs to be used according to a mapping relationship between each set of SRs configured on the network side and the specific indication information or the specific indication information combination.

Step 305, the terminal sends the SR to the network side device.

The terminal sends the SR to the network device according to the SR resource determined in step 304.

The network side device may determine, according to the received SR resource group corresponding to the SR resource, the specific indication information or the combination of the specific indication information corresponding to the SR resource group.
