Description

Resource allocation control method, device and system
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for controlling resource allocation.
Background
In a Long Term Evolution (LTE) system, a protocol architecture of a User plane at a side of a User Equipment or a terminal (User Equipment, UE) according to a related technology is shown in fig. 1. From bottom to top, the protocol layer is divided into the following protocol layers: a Physical layer (PHY), a Media Access Control (MAC), a Radio Link Control (Radio Link Control, RLC), and a Packet Data Convergence (PDCP). The PHY layer mainly transmits information to the MAC layer or a higher layer through a transmission channel; the MAC layer mainly provides data transmission and is responsible for wireless resource allocation through a logical channel, and completes functions such as Hybrid ARQ (HARQ for short), Scheduling (SCH for short), priority processing, Multiplexing and demultiplexing (MUX for short), and the like; the RLC layer mainly provides segmentation and retransmission services for user and control data; the PDCP layer mainly performs user data transfer to a Radio Resource Control (RRC) layer or an upper layer of a user plane. When a terminal establishes a Data Radio Bearer (DRB for short), a base station allocates a Logical Channel Group (LCG for short) to which the DRB belongs, where the LCG currently has four groups of 0, 1, 2, and 3. When a terminal in a connected state needs to send uplink data, if there is no uplink resource or grant, a Buffer Status Report (BSR) is sent to the base station first, carrying an index value corresponding to the size of the Buffer data prepared on the LCG, after the base station receives the index value, the base station knows the size of the Buffer data and configures corresponding uplink grant for the terminal, and the terminal can send the uplink data after receiving the uplink grant. The buffered data size contains buffered data of the corresponding data radio bearer on the LCG at the RLC layer and the PDCP layer.
After introducing Carrier Aggregation (CA), the UE may simultaneously communicate with the source base station through a plurality of component carriers (e.g., CC1, CC2) after entering a connected state, and introduce a Primary serving Cell (Pcell) and a Secondary serving Cell (Scell). In the subsequent stage of carrier aggregation, due to the increase of the data volume, the number of scells may be increased, for example, to 4, the scenario may also be widened, for example, a problem that a Remote Radio Head (RRH) and a repeater (repeater) are supported, and a Tracking Area (TA) cannot be solved, so that a plurality of TAs may be introduced. For convenience of management, the serving cells using the same TA are classified into one TA group. At this time, the TA group including Pcell is pTAG (primary TA group), and the TA group not including Pcell is sTAG (secondary TA group). Because a plurality of serving cells are in the same base station, the protocol architecture of the user plane is not changed, and the reporting mode of the BSR only increases the reported buffer data according to the increase of the data volume, and the others are not changed. A terminal supporting carrier aggregation is called a CAUE.
Due to the requirement of network deployment, a plurality of base stations may be deployed nearby, and the time delay between the base stations is very short, so that carrier aggregation of cells between the base stations is possible. However, since the cells of multiple base stations perform carrier aggregation, the conventional carrier aggregation technology cannot be reused completely.
Aiming at the problem of low resource utilization rate when carrier aggregation is carried out among cells in the related art, no effective solution is provided at present.

In this embodiment, the master base station may, but is not limited to, determine the physical resources allocated on the cell according to the proportion of the physical resources remaining in the cell to the total remaining physical resources. For example: the master base station may determine a first physical resource allocated on the first cell according to a first ratio of remaining physical resources in the first cell to all remaining physical resources, and may determine a second physical resource allocated on the second cell according to a second ratio of remaining physical resources in the second cell to all remaining physical resources. Alternatively, the master base station may, but is not limited to, respectively determine the physical resources allocated on the cell to process the buffered data corresponding to each logical channel group according to the group identification of each logical channel group.
In the present embodiment, the main base station may acquire indication information indicating the transmitted buffered data by receiving the buffer status report, but is not limited thereto.
In this embodiment, the buffer status may be, but is not limited to, a buffer status of the terminal, or a buffer status of each DRB, or a buffer status of each cell.
In this embodiment, the manner in which the primary base station acquires the resource status indication information of the secondary base station may be, but is not limited to, at least one of the following: and acquiring when the second physical resource of the auxiliary base station changes through timing acquisition.
In this embodiment, the primary base station (P-eNB) may notify the secondary base station (S-eNB) of information about quality of Service (QoS), including QoS information that the S-eNB needs to satisfy, or QoS partition ratios, such as delay, bit rate, and the like. The primary base station may effect allocation of resources through control of quality of service (QoS). Such as by the primary base station and the secondary base station sharing the quality of service.
The information of the auxiliary base station is notified by the main base station in batches; semi-persistent state or static information, such as SE, total number of PRBs on related carriers, etc., may be notified to the P-eNB when the terminal configures a cell on the S-eNB, or the P-eNB may estimate according to related configuration signaling. Other dynamically changing information is notified when the relevant information changes, or is notified at regular time.
The following describes a process of resource allocation control in this embodiment by way of an example.
In order to solve the problem that flow control between base stations cannot be achieved when carrier aggregation is performed between cells, a new user plane protocol architecture is proposed in this example, as shown in fig. 3, a data radio bearer is divided among a plurality of base stations, that is, data of one data radio bearer is sent through a plurality of base stations (MeNB), where the plurality of base stations include a primary base station (PCell eNB, abbreviated as P-eNB) and at least one secondary base station (SCell eNB, abbreviated as S-eNB). Wherein the P-eNB includes at least a primary cell (PCell) of the UE carrier aggregation cell and may include one or more secondary cells (scells) of the UE carrier aggregation cell. The S-eNB contains one or more scells of the UE carrier aggregation cell. As shown in fig. 3, the PDCP layer and the RLC layer may exist only in one base station, but the MAC layer exists in each base station, wherein the MAC layer on the P-eNB includes all functions of MAC including a data packet packing function, and the MAC layer on the S-eNB includes at least a data packet packing function. It should be noted that the above architecture is one of the methods for solving the above problems, and does not exclude other protocol architectures, and is not limited in the present invention.
The radio resources may be allocated and used by Physical Resource Blocks (PRBs), and each PRB corresponds to a specific Resource in the frequency domain and the time domain.
For uplink data, the terminal reports the BSR to the P-eNB, and the size of the buffer data of the corresponding data radio bearer on each LCG on the terminal is carried. And after receiving the information, the P-eNB allocates the BSR size for processing the buffer data on the P-eNB and the S-eNB according to the resource state information notified by the S-eNB and the current resource state information of the P-eNB, and notifies the S-eNB of the result. The S-eNB schedules data according to the result. The results include the resources required by the respective LCGs, i.e., the data transmitted over the respective LCGs.
For downlink data, the P-eNB allocates the size of data processed on the P-eNB and the S-eNB according to the size of the downlink data, the resource state information notified by the S-eNB and the current resource state information of the P-eNB, and notifies the S-eNB of the result. The S-eNB schedules data according to the result.
And the resource state information which is notified to the P-eNB by the S-eNB comprises the Spectrum Efficiency (SE) of each carrier on the S-eNB and the remaining PRB number of the related carrier on the S-eNB. The number of remaining PRBs on the relevant carrier may include the number of remaining PRBs on the relevant carrier, or include the total number of PRBs on the relevant carrier excluding the number of PRBs occupied by the common channel on the relevant carrier, and the number of PRBs occupied by the non-CAUE, or include the number of PRBs occupied by the CAUE and the number of idle PRBs on the relevant carrier.
Optionally, in step S206, the main base station may obtain the remaining physical resources in the first cell and the remaining physical resources in the second cell according to the resource status indication information of the main base station and the resource status indication information of the secondary base station, and then determine the first physical resources allocated to the first cell and the second physical resources allocated to the second cell for processing the buffered data according to at least the remaining physical resources in the first cell and the remaining physical resources in the second cell. Through the steps, the main base station can acquire the residual physical resources in the cell corresponding to the base station in the resource state indication information of the main base station and the auxiliary base station, and then determine the physical resources which are allocated on the cell and used for processing the buffer data according to the residual physical resources in the cell, so that the scheduling and the allocation of the residual physical resources in the cell are realized.
Alternatively, the manner of acquiring the remaining physical resources may be one of the following three manners:
the first method is as follows: and acquiring the sum of the physical resource size occupied by the common channel on the cell carrier and the physical resource size occupied by the non-support carrier aggregation terminal and the difference between the sum and the total physical resource size, and taking the difference as the resource size corresponding to the residual physical resource.
The second method comprises the following steps: and acquiring a sum of the physical resource size occupied by the carrier aggregation supporting terminal on the cell carrier and the idle physical resource size, and taking the sum as the resource size corresponding to the residual physical resource.
The third method comprises the following steps: and taking the resource size corresponding to the buffer state level as the resource size corresponding to the residual physical resources, wherein the buffer state comprises at least one of the following: terminal buffer status, data radio bearer buffer status, and cell buffer status.
Through the steps, the main base station can acquire the residual physical resources of the cell of the main base station or the cell of the auxiliary base station in different modes, so that the residual physical resources of the cell can be flexibly distributed.
Optionally, the primary base station may obtain a first ratio of the remaining physical resources in the first cell to all the remaining physical resources and/or a second ratio of the remaining physical resources in the second cell to all the remaining physical resources, and then determine, according to at least the first ratio and/or the second ratio, a first physical resource allocated to the first cell for processing the buffered data and a second physical resource allocated to the second cell. Through the steps, the main base station can determine the physical resources distributed on the cell by calculating the proportion of the residual physical resources in the cell to all the residual physical resources, so that the flexible distribution of the physical resources is realized.
Alternatively, the master base station may, but is not limited to, determine the allocated first physical resource on the first cell and the allocated second physical resource on the second cell for processing the buffered data corresponding to each Logical Channel Group (LCG) according to the group identity of the respective LCG, respectively.
Optionally, the resource status indication information of the master base station may further include, but is not limited to: spectrum efficiency of a first frequency to which a first cell in a master base station belongs; the resource status indication information of the secondary base station may include, but is not limited to: the spectrum efficiency of the second frequency to which the second cell belongs in the secondary base station, wherein the primary base station may obtain the first ratio and the second ratio through the following formulas:
r1＝s1*R1/(s1*R1+s2*R2)，
r2＝s2*R2/(s1*R1+s2*R2)，
where R1 denotes a first ratio, R2 denotes a second ratio, s1 denotes a spectral efficiency of a first frequency to which the first cell belongs, R1 denotes a remaining physical resource in the first cell, s2 denotes a spectral efficiency of a second frequency to which the second cell belongs, and R2 denotes a remaining physical resource in the second cell.
Optionally, in step S202 above, the main base station may, but is not limited to, obtain indication information for indicating the transmitted buffered data through a buffer status report sent by the receiving terminal, where the buffer status report carries at least indication information for indicating a data amount of uplink buffered data to be sent by the receiving terminal.
Optionally, in step S204, the manner in which the primary base station acquires the resource status indication information of the secondary base station may include, but is not limited to, at least one of the following: the main base station acquires the resource state indication information of the auxiliary base station at regular time; and the main base station acquires the resource state indication information of the auxiliary base station when the second physical resource on the auxiliary base station changes.
In one example, an RRC connection is established between the primary base station and the terminal, and the primary base station may control data transmitted between the primary base station and the terminal and between the secondary base station and the terminal according to information reported by the terminal and the secondary base station. Fig. 4 is a flowchart of another alternative resource allocation control method according to an embodiment of the present invention, and as shown in fig. 4, the flowchart includes the following steps:
step S402, establishing RRC connection between the main base station and the terminal;
in step S404, the primary base station receives the information notified by the secondary base station. For example: information such as the spectral efficiency of the designated frequency, the number of remaining PRBs, the number of PRBs occupied by a common channel, the number of PRBs occupied by non-CAUE, the number of PRBs occupied by CAUE, the number of idle PRBs, and the like;

and step S418, the terminal sends data to the secondary base station according to the received uplink authorization.
It should be noted that step S416 and step S418 may be executed simultaneously or sequentially, and are not limited in this example.
The resource allocation control method of the present embodiment is illustrated and described below in accordance with an alternative embodiment.
In the following optional embodiments, the primary base station (P-eNB) takes base station 1 as an example, and has 1 cell, which is cell 1 and belongs to frequency point f1, and the secondary base station (S-eNB) takes base station 2 as an example, and has two cells, which are cell 3 and cell 4 respectively, and belong to frequency point f3 and frequency point f4 respectively. The first scheduling command is exemplified by a first uplink grant, and the second scheduling command is exemplified by a second uplink grant.
It should be noted that the following alternative embodiments are all described for data radio bearers, and are also valid for signaling radio bearers, and are not described herein again.
In an optional embodiment one, the S-eNB directly notifies the SE and the remaining PRBs to the P-eNB, the terminal establishes a connection with the cell 1, the number of PRBs of the cell 1 is 80, because the traffic volume increases, the base station 1 adds the cell 3 to the terminal according to the measurement report, the number of allocated PRBs of the cell 3 is 100, and there are two data radio bearers, which are the data radio bearer 1 and the data radio bearer 2 respectively, and both belong to the LCG 0. The resource allocation control method according to the first embodiment includes the steps of:
the method comprises the following steps: the base station 2 calculates and saves the spectral efficiency SE-3 of the frequency f3 to which the cell 3 belongs, which is 0.6 at this time, and notifies the base station 1. The base station 2 can re-notify or notify at regular time when the subsequent change occurs;
the base station 2 calculates the number of remaining PRBs on cell 3, which is then 60, and informs base station 1. The base station 2 may re-notify at a later time when there is a change, or notify at a timing.
Step two: when the terminal needs to send uplink data, the terminal reports the BSR to the base station 1, the size of the buffered data including the two data radio bearers is 680 at this time, and the size of the buffered data carrying the LCG0 is an index value corresponding to 680. LCGs 1, 2, 3 have no data radio bearer, so the buffered data size is 0.
Step three: the base station 1 receives the BSR reported by the terminal, and calculates the number BSRcc-3 of PRBs corresponding to the data volume to be processed by the cell 3 according to the following formula, based on that the spectral efficiency SE-3 of the frequency f3 to which the cell 3 belongs is 0.6 at this time, and based on that the number of remaining PRBs on the cell 3 known from the base station 2 is 60 at this time, and that the spectral efficiency SE-1 of the frequency f1 to which the serving cell 1 on the base station 1 belongs is 0.7 at this time, and that the number of remaining PRBs on the cell 1 is 40 at this time:
BSRcc-3 (BSR) (680) × (SE-3(0.6) × number of PRBs remaining on carrier 3 (60)/(PRBs remaining on carrier 1 (40) × SE-1(0.7) + SE-3(0.6) × number of PRBs remaining on carrier 3 (60))) (382) reported by UE (382) (BSR) (sr) (3) (SE-3) (0.6) (3) (SE-3) (0.6) ()))) number of PRBs) (remaining PRBs) (PRB remaining on carrier 3) (PRB) 3) (PRB remaining on carrier 3) (60) (PRB number of PRBs) (60) (PRB) on carrier 1) (sr) (SE (1)))))) (SE (1) (SE) (1) (SE (0.6) (carrier 3) (sr) (2) (sr) (2) (sr) (2) (sr) (carrier 3) (sr) (2) (sr) (2) (pr) (carrier 3) (pr) (carrier 3) (remaining) (PRBs) (carrier 3) (PRBs) (carrier 3) (PRBs) (carrier 3) (PRBs) (carrier 3) (PRBs) (number of) (PRBs) (60))))))))))))))))))))(s) (carrier 3) (number of) (carrier 3) (
Thus, it follows: cell 1 needs to process 298 data, cell 3 needs to process 380 data, and LCG0 on cell 3 needs to allocate 382 resources.
The base station 1 notifies the S-eNB of the resource that the LCG0 needs to allocate 382 on the cell 3, and may also carry other information, such as a terminal identifier.
Step four: upon receiving the notification from the base station 1, the base station 2 reserves resources and transmits a second uplink grant (grant size is 382 or more, and cell throughput (TBSize) closest to 382) to the terminal.

Step five: the terminal receives the uplink authorization of the base station 1 and the base station 2, and sends the data on the two radio bearers through the two authorized resources respectively, and how to distribute the data for sending is determined by the terminal.
In addition, when the base station 1 transmits downlink data, the processing procedure is similar, the base station 1 knows that the spectral efficiency SE-3 of the frequency f3 to which the cell 3 belongs from the base station 2 is 0.6 at this time, and that the number of remaining PRBs on the cell 3 known from the base station 2 is 60 at this time, and that the spectral efficiency SE-1 of the frequency f1 to which the terminal belongs to the serving cell 1 on the base station 1 is 0.7 at this time, and that the number of remaining PRBs on the cell 1 is 40 at this time, and the data that the cell 1 needs to process and the data that the cell 3 needs to process are calculated according to the above formula, and the base station 1 notifies the base station 2 of the resources that need to be allocated on the cell 3, and may also carry other information, such as a terminal identifier.
