Resource scheduling method and related equipment and system

Technical field

The present invention relates to the field of communications technologies, and in particular, to a resource scheduling method and related devices and systems.

Background technique

In a Long Term Evolution (LTE) system, when a user equipment (User Equipment, UE) has an uplink service to transmit, the UE may send an uplink scheduling to an evolved Node B (eNB) in an uplink subframe. After the SRI is detected by the eNB, the eNB allocates a small number of resource blocks (RBs) to the UE in the downlink subframe, and the UE can use the small number of RBs to report the service information and the buffer status. The MAC Control Elements (MCE) information, such as the Buffer Status Report (BSR) and the Power Headroom Report (PHR), is reported to the eNB. The eNB needs to perform resource scheduling on the UE again after the eNB obtains the MCE information, and the eNB obtains the MCE information to determine that the first allocated RB cannot meet the RB required by the UE to transmit the data packet. The reassigned RB uploads the remaining packets.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The terms "including" and "comprising" and "comprising", and any variations thereof, are intended to cover a non-exclusive inclusion, such as a process or method comprising a series of steps or units. A system, product, or device is not limited to the listed steps or units, but optionally includes steps or units not listed, or alternatively other steps inherent to those processes, methods, products, or devices Or unit.

The embodiment of the invention discloses a resource scheduling method and related device and system, which can perform resource scheduling on the UE in a targeted manner and improve the rationality of resource scheduling. The details are described below separately.

In order to better understand a resource scheduling method disclosed in the embodiment of the present invention, a network architecture to which the embodiment of the present invention is applied is first described. Referring to FIG. 1, FIG. 1 is a schematic diagram of a network architecture disclosed in an embodiment of the present invention. In the network architecture shown in FIG. 1, the base station and a plurality of user equipments (UEs), such as UE1, UE2, ..., UEn (n is a positive integer), may be included. The base station can simultaneously perform communication connection with multiple user equipment UEs.

A base station, that is, a public mobile communication base station, is a form of a radio station, and refers to a radio transceiver station that transmits information to and from a user equipment through a mobile communication switching center in a certain radio coverage area. The base station described in this document may have different functions and corresponding network configurations in different network scenarios, which is not limited by the present invention. For example, in some network scenarios, the base station may also be referred to as an eNB (Evolved Node B). In addition, the base station may also include a future 5G base station.

The user equipment UE may include, but is not limited to, a handheld device having a wireless communication function (such as a mobile phone, a tablet, a personal digital assistant, etc.), an in-vehicle device, a wearable device (such as a smart watch, a smart bracelet, etc.), a computing device, or a connection. Other processing devices to the wireless modem, as well as various shapes Mobile station (MS), user equipment (Terminal), user equipment equipment (Terminal Equipment) and so on. For convenience of description, in the present application, it is simply referred to as a user equipment or a UE.

In the embodiment of the present invention, the network architecture shown in FIG. 1 may be applicable to a scenario in which a base station performs resource scheduling for a UE. Generally, the base station informs the UE of the location of the resource block (Resource Block, RB) for information transmission, and informs the UE to receive information on the corresponding RB in the downlink transmission, and transmits the information on the corresponding RB in the uplink transmission.

In the LTE (Long Term Evolution) system, the process of the resource scheduling by the traditional base station for the UE may be: when the UE has an uplink service to send, the UE may send the uplink to the evolved base station. After the SRI is detected by the eNB, the eNB allocates a small number of RBs to the UE in the downlink subframe, and the UE can use the small number of RBs to report the service information and the buffer status (BSR Status Report, BSR). The MAC Control Elements (MCE) information such as power headroom report (PHR) is sent to the eNB. The eNB needs to perform resource scheduling on the UE again after the eNB obtains the MCE information, and the eNB obtains the MCE information to determine that the first allocated RB cannot meet the RB required by the UE to transmit the data packet. The reassigned RB uploads the remaining packets.

In practice, it is found that some of the uplink services sent by the UE are sensitive to delays, such as control services and voice services. These uplink services need to preferentially allocate resource guarantee delays. However, the above-mentioned scheme in which the base station performs resource scheduling on the UE cannot perform differentiated processing for the UE, and the scheduling mode has blindness.

Based on the foregoing situation, in the embodiment of the present invention, after the base station allocates the first resource block RB to the user equipment UE, the base station may receive the medium access control element MCE information that is sent by the UE using the first RB, where the MCE information carries There are customized logical channel identification LCID information that can be identified by both the base station and the UE. For example, the transmission control protocol confirms the packet sending time of the TCP ACK packet, the size of the TCP ACK packet, and the radio link layer control protocol confirms the packet sending of the RLC ACK packet. Time, the size of the RLC ACK packet, the time of sending the measurement report packet, the size of the measurement report packet, the time of sending the control signaling packet, the size of the control signaling packet, the time of sending the voice packet, and the language The size of the audio packet. The base station may perform resource scheduling on the UE according to the LCID information. For example, the base station may allocate resources to the UE in advance at the time of sending the data packet to ensure the delay. For example, the base station may accurately estimate the scheduling data amount of the UE according to the size of the data packet, and ensure the scheduling resource. To prevent data fragmentation.

In the method flow described in FIG. 1 , the existing protocol specifies the common LCID information of all the base stations and the UE (for example, the buffer status report BSR information and the power headroom report PHR information). In the embodiment of the present invention, the The customized LCID information is compared to the new LCID information in the existing protocol. The customized LCID information between the UE and the base station is different. The base station performs resource scheduling on the UE according to the customized LCID information that the base station and the UE can identify, and improves the rationality of the resource scheduling.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of a resource scheduling method according to an embodiment of the present invention. As shown in FIG. 2, the resource scheduling method may include the following steps:

201. The base station sends, to the UE, a first LCID format that the base station can support.

Referring to FIG. 2a, FIG. 2a is a schematic diagram of a MAC header according to an embodiment of the present invention. As shown in FIG. 2a, where R is a reserved bit, and E is an extended field, which is used to indicate whether there are other domains in the MAC header after the domain; LCID (Logic Channel Identify), that is, each MAC The logical channel or the type of each MAC control unit corresponding to the SDU (Media Access Control Service Date Unit) is filled with 5 bits; F is the format field, indicating the length of the length field; L is the length field, indicating The number of bytes (7 or 15 bits) of the corresponding MAC SDU or MAC Control Unit. There are multiple control information units in the MAC, for example, a Buffer Status Report (BSR). The UE can send a Medium Access Control (MCE) message carrying a BSR to the base station to notify the base station. How much data the base station UE needs to transmit. For another example, the power headroom report (PHR), the UE may send the MCE information carrying the PHR to the base station to inform the base station of the remaining power of the UE. In addition, the LCID is used in the MAC subheader to distinguish different control information elements.

Referring to Table 1 and Table 2 together, Table 1 is an LCID format in a MAC header disclosed in the embodiment of the present invention, and Table 2 is an LCID format in another MAC header disclosed in the embodiment of the present invention. The LCID format shown in Table 1 is for downlink services, and the LCID format shown in Table 2 is for uplink services.

Table 1

Table 2

It should be noted that the LCID formats shown in Table 1 and Table 2 are all LCID formats in the traditional MAC header. In the existing protocol, only the BSR and the PHR are available for the base station in the LCID format in the conventional MAC header. For the resource scheduling of the UE, under the existing protocol mechanism, the MCE information reported by the UE is limited, and the base station cannot distinguish which UEs have special services (such as delay-sensitive services) based on the limited MCE information, and thus cannot Priority is given to allocate fast resource RBs to these UEs with special services. The current resource scheduling method has blindness and unreasonable scheduling.

In order to solve the above problem, the base station may send a first LCID format that the base station can support to the user equipment UE accessing the base station in a broadcast form before the base station performs resource scheduling for the UE, where the first LCID format is used to define An index number in the MAC header and first LCID information that matches the first LCID format. The first LCID information includes, but is not limited to, a transmission control protocol confirming a packet sending time of the TCPACK packet, a size of the TCP ACK packet, a radio link layer control protocol confirming a packet sending time of the RLC ACK packet, and a size of the RLC ACK packet. And measuring the packet sending time of the data packet, the size of the measurement report data packet, the time of sending the control signaling data packet, the size of the control signaling data packet, the time of sending the voice data packet, and the size of the voice data packet. In addition, it should be noted that the first LCID information may also include information specified in an existing protocol, such as BSR information and PHR information.

202. The UE sends a second LCID format that the UE can support to the base station.

As an optional implementation manner, after the UE, the UE may send a Hybrid Automatic Repeat ReQuest (HARQ) feedback to the base station. If the UE successfully receives the first LCID format sent by the base station, the HARQ feedback is Correctly, step 202 can be performed at this time; if the UE does not receive the first LCID format sent by the base station or the UE cannot identify the first LCID format sent by the base station, the HARQ feedback is an error. At this time, the base station needs to wait for N transmission moments. Step 201 is repeated after the Transmission Time Interval (TTI), and step 202 is performed until the HARQ feedback is correct, where N is a positive integer. Optionally, if the HARQ feedback is not obtained within the preset time, the current process ends.

In the embodiment of the present invention, after the UE successfully receives and identifies the first LCID format sent by the base station, the UE may send a second LCID format that the UE can support to the base station, where the second LCID format is used to define An index number in the MAC header and second LCID information that matches the second LCID format. The second LCID information includes, but is not limited to, a transmission control protocol confirming a packet sending time of the TCP ACK packet, a size of the TCP ACK packet, a radio link layer control protocol confirming an RPC ACK packet sending time, and an RLC ACK packet. The size, the time of sending the measurement report packet, the size of the measurement report packet, the time of sending the control signaling packet, the size of the control signaling packet, the time of sending the voice packet, and the size of the voice packet. In addition, it should be noted that the second LCID information may further include information specified in an existing protocol, such as BSR information and PHR information.

203. The base station determines LCID information added by the base station and the UE from the first LCID information and the second LCID information, and determines the newly added LCID information as customized LCID information that can be identified by the base station and the UE.

Compared with the BSR information and the PHR information, the other LCID information in the embodiment of the present invention belongs to the newly added information, for example, the transmission control protocol confirms the time of sending the TCP ACK packet, The size of the TCP ACK packet, the radio link layer control protocol confirms the time of sending the RLC ACK packet, the size of the RLC ACK packet, the time of sending the measurement report packet, the size of the measurement report packet, and the control signaling packet. The time of sending the packet, the size of the control signaling packet, the time of sending the voice packet, and the size of the voice packet.

In the embodiment of the present invention, after receiving the second LCID format sent by the UE, the base station may determine, from the first LCID information and the second LCID information, the LCID information added by the base station and the UE, and determine the newly added LCID information. Customized LCID information that can be recognized by both the base station and the UE. The customized LCID information is compared to the new LCID information in the existing protocol.

In this way, when the subsequent base station performs resource scheduling for the UE, the base station can perform reasonable resource scheduling on the UE according to the customized LCID information between the UE and the base station.

204. The base station allocates a first resource block RB to the UE.

Optionally, the specific implementation manner that the base station allocates the first resource block RB to the UE may be:

In the optional implementation, when the UE needs to send the uplink service to the base station, the UE sends an uplink scheduling request indication (SRI) to the base station, and the base station detects the uplink scheduling request indication SRI sent by the UE. The base station will allocate the first resource block RB to the user equipment UE. Generally, the first RB is a small number of resource blocks, and is mainly used for reporting the MCE information required for resource scheduling by the UE.

In addition, in the process of pre-scheduling the UE, the base station does not need to send the SRI to the base station, and the base station can directly allocate the first resource block RB to the user equipment UE.

205. The UE determines a first resource block RB that the base station allocates for the UE.

206. The UE adds the customized logical channel identifier LCID information that can be identified by the base station and the UE to the medium access control element MCE information.

Specifically, the UE adds the customized logical channel identifier LCID information that can be identified by the base station and the UE to the reserved field of the MAC header to generate the MCE information. The customized LCID information is used by the base station to perform resource scheduling for the UE.

Referring to Table 3, Table 3 is the LCID information in the reserved field of the MAC header disclosed in the embodiment of the present invention.

It should be noted that, in Table 3, other parts of the MAC header (such as CCCH, logical channel identifier, PHR, BSR, etc.) are the same as the conventional MAC header, and different from the conventional MAC header, in the embodiment of the present invention, Customized LCID information that can be recognized by both the base station and the UE is added to the reserved field in the MAC header.

as shown in Table 3:

207. The UE sends the MCE information added with the customized LCID information to the base station by using the first RB.

208. The base station performs resource scheduling on the UE according to the customized LCID information.

In the embodiment of the present invention, after the base station receives the MCE information that is added by the UE and adds the customized LCID information, the base station may perform resource scheduling on the UE according to the customized LCID information.

For example, if the customized LCID information includes the time of sending the TCP ACK packet, the base station can increase the scheduling priority of the UE at the time of sending the TCP ACK packet, that is, preferentially scheduling the resource for the UE to ensure Scheduling opportunities.

For example, if the size of the TCP ACK packet is included in the customized LCID information, the base station can accurately estimate the scheduling data of the UE at a specific scheduling moment, and allocate the RB that is consistent with the size of the TCP ACK packet to the UE. Guarantee scheduling resources to prevent data fragmentation.

In addition, in the embodiment of the present invention, the UE can report the MCE information carrying the customized LCID information to the base station in advance, and the base station can perform an optimal operation during scheduling, so that in the overload scenario, the key performance indicator can be improved ( Key Performance Indicators (KPI), reducing the number of time delays, High cell throughput. At the same time, the base station accurately estimates the scheduling data of the UE at a specific scheduling time, which can reduce collisions of uplink data transmissions of different UEs and reduce uplink interference.

It should be noted that, in the embodiment of the present invention, the base station is a new base station capable of identifying customized LCID information, and the UE is a new UE capable of identifying customized LCID information, that is, performing interaction between the new base station and the new UE. For an old base station or an old UE that cannot identify the customized LCID information, scheduling can be performed in a conventional manner, that is, it does not affect the normal interaction between the new base station and the old UE, and does not affect the old base station and the new UE. The normal interaction between.

In the method flow described in FIG. 2, the base station interacts with the UE in advance to determine customized LCID information that can be identified by the base station and the UE. When the base station allocates the first RB to the UE, the base station may perform the customized LCID reported by the UE. The information is used to perform resource scheduling on the UE in a targeted manner, thereby improving the rationality of resource scheduling.
