Description

METHOD AND APPARATUS FOR WIRELESS RESOURCE SCHEDULING IN WIRELESS NETWORKS This application claims to be filed on March 23, 2012, the Chinese Patent Office, Application No. 201210092882.X, entitled "Method for Radio Resource Scheduling in Wireless Networks" The priority of the Chinese Patent Application, the entire disclosure of which is incorporated herein by reference. Technical field

The present invention generally relates to a Radio Access Technology (RAT) network, and in particular, to a method and apparatus for radio resource scheduling in a multi-RAT network. Background technique

Existing wireless networks include a variety of wireless access technologies, such as 2G, 3G, Long Term Evolution (LTE), Advanced Long Term Evolution (LTE-A), and the like. 1 is a schematic diagram of an existing multi-RAT network. As shown in FIG. 1, in an existing multi-RAT network, there is a central controller, gp, Radio Resource Management Equipment (RRME) 110, which is connected to the core network 100 and connected to, for example, 2G, 3G. Multiple base stations (BS: Base Stations) 120, 130, 140, and 150 of one or more RATs such as LTE. The existing radio resource management device 110 can only manage information related to handover and/or cell reselection between terminals (Terminal), for example, the radio resource management device 110 can collect information about cell capacity and load. Help the base station to determine the target cell.

Taking the scheduling of the base stations of different RATs as an example, it is assumed that the serving base stations of the terminal 1 and the terminal 2 at the edge of the neighboring cell are the base station 1 and the base station 2, respectively, and the corresponding wireless networks are RATI and RAT2, respectively. In general, base station 1 and base station 2 independently schedule terminal 1 and terminal 2 to allocate data transmission resources, such as time, frequency, space, power, codewords, and the like. In the case that there is no direct interface between the base station 1 and the base station 2, since the two cannot exchange their respective resources, loads and other information, the respective resources cannot be coordinated and utilized, which affects the resource utilization of the entire wireless network to some extent. Even if RATI and RAT2 belong to the same access technology and may have an interface between base station 1 and base station 2, it may be caused by independent scheduling of base station 1 and base station 2. Terminal 1 and terminal 2 may interfere with each other during data transmission, thereby affecting the overall throughput performance of the system. Taking an LTE system as an example (a base station is also referred to as an evolved Node B (eNodeB) in an LTE system, and a terminal is also referred to as a User Equipment (UE)), in the case where an X2 interface is provided between the eNodeB1 and the eNodeB2 The UE1 and UE2 served by each of them may still interfere with each other during data transmission. Although an inter-cell interference coordination (ICIC) technique such as Inter-cell Interference Coordination (ICIC) is proposed in the LTE system to improve the mutual interference between edge UEs, the ICIC technology still has its limitations. The ICIC technology is implemented by interfacing the eNodeB via the X2 interface to load information (LI: Load Information) signaling. If there is no X2 interface between adjacent eNodeBs, ICIC technology cannot be used to eliminate uplink and downlink interference between edge terminals. In addition, as specified in 3GPP TS 36.423, the LI signaling includes an overload indication (01: Overload Indication), a High Interference Indication (HII), and a Relative Narrowband Transmission Power (RNTP). Information, however, provides only information related to the Physical Resource Block (PRB) and does not provide more information related to scheduling radio resources for the terminal.

It can be seen that in the existing multi-RAT network, the independent scheduling of the base station is not optimal in terms of system throughput, interference, power saving, resource utilization and the like. Therefore, there is a need for a technique that can facilitate efficient radio resource scheduling in a multi-RAT network to reduce or eliminate uplink and downlink interference, improve resource utilization, and effectively avoid system throughput loss.

And RAT2. 2 exemplarily shows two base stations 1 and 2 and their respective served terminals 1 and 2, it being understood that a plurality of other base stations and terminals performing similar functions may also be included in the actual wireless network. . An exemplary embodiment of the present invention for performing radio resource scheduling will be specifically described below in conjunction with the network shown in FIG.

FIG. 3 illustrates an exemplary flow diagram for wireless resource scheduling in accordance with an embodiment of the present invention. In step S310, the base station 1 and the base station 2 can respectively send scheduling information to the radio resource management device. Similarly, other base stations in the radio network can also send respective scheduling information to the radio resource management device. The scheduling information may include information about radio resources scheduled by the base station for the scheduled terminals it serves. In some cases, the scheduled radio resources reflected by the scheduling information can guarantee the quality of service (QoS) of the scheduled terminals. The scheduling information may include, for example, an allocated time resource corresponding to the scheduled terminal, an allocated frequency resource, an allocated spatial resource, an allocated codeword resource, a used transmission power, a service QoS, a transmission rate, a scheduling period, a terminal location, Information from one or more of the multipoint collaboration collections. In addition, the scheduling information may also include a cell identity and a terminal identity corresponding to the scheduled terminal.

For example, in the LTE/LTE-A system, the scheduling information may further specifically include: information about a physical layer resource block (PRB), a multipoint cooperation set including a plurality of eNodeBs serving the UE, or a low power node, and the like. Optionally, the base station may periodically send scheduling information to the radio resource management device. In addition, optionally, the base station may also send scheduling information based on requirements of the radio resource management device. For example, the radio resource management device may first send a request for acquiring scheduling information to the base station, and then the base station may transmit the scheduling information in response to the request.

Alternatively, the terminal corresponding to the transmitted scheduling information may be a low speed mobile terminal located at the edge of the coverage of its serving base station. It will be apparent to those skilled in the art that the location of the terminal can be determined by various techniques such as Reference Signal Receiving Power (RSRP), Beamforming, or GPS.

In step S320, the radio resource management device may generate scheduling reference information based on scheduling information received from a plurality of base stations (eg, base station 1, base station 2, and other base stations in the network, which may be geographically overlapping or adjacent). . The scheduling reference information is generated based on the above scheduling information, and provides information that is required to be referenced when a base station (e.g., base station 1) schedules radio resources for a terminal (e.g., terminal 1) it serves. For example, the information of these references may relate to recommendations for radio resource scheduling of the base station, or information about radio resources that have been scheduled by multiple base stations in the network, and the like.

In step S330, the radio resource management device may transmit the generated scheduling reference information to the base station. For example, the radio resource management device may send the scheduling reference information to a specific base station (for example, the base station 1) indicating that the scheduling reference information is needed, or may actively send the scheduling reference information to multiple connected to the radio resource management device, respectively. Base station.

In step S340, the base station 1 can generate a scheduling result for the terminal 1 it serves based on the scheduling reference information received from the radio resource management device. The scheduling result may include information about the radio resources that the base station 1 schedules for the terminal 1. The terminal 1 may be a low-speed mobile terminal located at the edge of the coverage of the base station 1. In the process of generating the scheduling result by the base station 1, for example, the base station 1 may consider the proposal of the radio resource scheduling provided in the scheduling reference information, or consider the radio resources that have been scheduled by the plurality of base stations in the network as reflected in the scheduling reference information. Information to reduce or avoid interference, or to improve resource utilization.

In step S350, the base station 1 may send the scheduling result to the terminal 1 to implement the radio resource scheduling for the terminal 1.

Through the embodiment shown in FIG. 3, scheduling information of each base station may be collected at the radio resource management device, and scheduling reference information may be generated according to the scheduling information for the base station to schedule for the terminal. The radio resource is referenced, so that the base station can consider the scheduling situation of other base stations when performing radio resource scheduling, reduce or avoid interference, or improve resource utilization.

FIG. 4 shows an exemplary flow diagram for wireless resource scheduling in accordance with another embodiment of the present invention. The method shown in Fig. 4 relates to a scenario in which the radio resource management device transmits scheduling reference information to the base station 1 based on the request of the base station 1.

In step S410, the base station 1 and the base station 2 can respectively transmit scheduling information to the radio resource management device. This step is similar to step S310 in Fig. 3.

In step S420, the base station 1 may send a scheduling request to the radio resource management device. Specifically, the base station 1 may first select the terminal 1 to be scheduled radio resources within its coverage. For example, the terminal 1 may be a low-speed mobile terminal at the coverage edge of the base station 1; then, the base station 1 may send the terminal 1 for the terminal 1. Schedule a request. The scheduling request may be a radio resource coordination request sent by the base station 1 for the terminal 1 it serves.

In one case, the scheduling request may include information related to the current operating conditions of the terminal 1. For example, the scheduling request may include information regarding one or more of a service QoS, a transmission rate, a used carrier, a maximum transmission power, a terminal location, and a coordinated multi-point set corresponding to the terminal 1. Further, the scheduling request may further include a cell identity and a terminal identity corresponding to the terminal 1.

In another case, the base station 1 may also attempt to allocate radio resources to the terminal 1 in advance, so that the scheduling request may include information about radio resources pre-allocated for the terminal 1. For example, the scheduling request may include information about pre-allocated time resources, pre-allocated frequency resources, pre-allocated spatial resources, pre-allocated codeword resources, pre-used transmit power, pre-used scheduling periods, pre-used multi-point collaboration One or more pieces of information in the collection. Furthermore, the scheduling request may also include a cell identity and a terminal identity corresponding to the terminal 1.

In step S430, the radio resource management device may generate scheduling reference information for the scheduling request based on scheduling information received from a plurality of base stations. Specifically, in the process of generating the scheduling reference information, the RRC device may perform the QoS of the scheduled terminal served by each of the multiple base stations according to the scheduling information of the multiple base stations and the scheduling request for the terminal 1 described above. Provides suggestions for scheduling radio resources for terminal 1. In some cases, the generation of scheduling reference information also needs to consider the ability to meet the QoS requirements of the terminal 1 itself. The scheduling reference information may include information about suggestions for radio resources to be used by the terminal 1.

For example, the RRC device may consider that other base stations have tuned to their respective served terminals. For the wireless resources, the base station 1 is prevented from scheduling the radio resources scheduled by the other base stations for the terminal 1 and providing suggestions for the radio resources to be used by the terminal 1 in the scheduling reference information. Optionally, in the process of generating the scheduling reference information, the radio resource management device may determine, according to the radio resources that the other base stations other than the base station 1 have scheduled to the respective scheduled radio resources, the radio resources, and then The information of the wireless resource is included in the scheduling reference information. Optionally, in order to save computing resources and reduce processing complexity, the radio resource management device may also consider only the neighboring base stations of the base station 1 (for example, the base station 2; usually multiple neighboring base stations) for the proximity of the base station 1 A radio resource scheduled by a scheduled terminal (e.g., terminal 2) of terminal 1. For example, the radio resource management device may suggest that the base station 1 schedule the radio resources other than the radio resources that the base station 2 has scheduled for the terminal 2 for the terminal 1. In this case, the scheduling reference information may include, for example, information about the proposed time resource, the suggested frequency resource, the proposed spatial resource, the suggested codeword resource, the recommended transmit power, the recommended scheduling period, and the recommended number. Point information for one or more of the collaboration collections. In addition, the scheduling reference information may also include a cell identifier and a terminal identifier corresponding to the terminal 1. Taking the LTE/LTE-A system as an example, it is assumed that the total number of PRBs corresponding to the system bandwidth is 10, if the RRC determines that the PRBs of No. 6-10 have been scheduled by other eNodeBs and the PRBs of No. 1-5 have not been used by others. For the eNodeB scheduling, the recommended PRB number included in the scheduling reference information sent to the eNodeB1 may be No. 1-5, thereby avoiding interference with UEs served by other eNodeBs.

In the case where the scheduling request described above includes information about radio resources pre-allocated for the terminal 1, the radio resource management device may first determine whether the pre-allocated radio resources are to be served by other base stations based on the scheduling information it receives. The UE generates interference. For example, the scheduling information may include information about radio resources scheduled by the neighboring base station 2 of the base station 1 for the terminal 2 adjacent to the terminal 1 that is served by the base station 1, so that the radio resource management device may be based on the terminal indicated in the scheduling information. 2 The scheduled radio resources are judged whether the resources overlap or partially overlap with the radio resources pre-allocated for the terminal 1, so that it can be determined whether the scheduling of the pre-assigned radio resources for the terminal 1 may cause interference to other terminals. If no interference is generated, the RRC device may include an consent indication in the scheduling reference information to indicate that the base station 1 can schedule the pre-allocated resources included in the scheduling request for the terminal 1. Alternatively, in this case, the radio resource management device may also include information about the radio resource pre-allocated for the terminal 1 included in the scheduling request in the scheduling reference information. If the pre-allocated resource or part of it causes interference, the wireless resource The source management device may provide further suggestions based on the pre-allocated resources in the scheduling request, for example, determining the recommended radio resources different from the pre-allocated radio resources, to prevent the base station 1 from scheduling the radio resources that other base stations have scheduled. Avoid interference with terminals served by other base stations. The suggested radio resources may include, for example, one of a suggested time resource, a suggested frequency resource, a suggested space resource, a suggested codeword resource, a recommended transmit power, a suggested scheduling period, and a suggested multipoint collaboration set. Or multiple. Then, the radio resource management device can include information about the suggested radio resource in the scheduling reference information. In addition, the cell identifier and the terminal identifier corresponding to the terminal 1 may be included in the foregoing scheduling reference information. Taking the LTE/LTE-A system as an example, it is assumed that the pre-allocated PRB number in the scheduling request is 6-10 (assuming that the total number of PRBs corresponding to the system bandwidth is 10), gp, eNodeB1 pre-allocates the number 6-10 for UE1. PRB. If the pre-assigned PRB does not interfere with the UE served by the other eNodeB on the uplink and downlink, the RRC device may send an indication of consent in the scheduling reference information to indicate that the eNodeB1 can schedule the No. 6-10 for the UE1. The PRB, or the radio resource management device, may also include the PRB number 6-10 in the scheduling reference information. If interference occurs on the pre-assigned PRBs No. 6-10, the RRMA may include the re-proposed PRB number in the scheduling reference information, for example, No. 1-5. If interference occurs on a part of the pre-allocated PRBs No. 6-10, for example, interference occurs on the 6th-7th PRB and does not cause interference on the 8th-10th PRB, the scheduling reference information may be This includes partially agreed PRB numbers, for example, Nos. 8-10.

In addition, optionally, in the process of generating scheduling reference information for a scheduling request including information related to the current working condition of the terminal 1 or for a scheduling request including information related to the wireless resource pre-allocated for the terminal 1, A recommendation for the radio resource to be used by the terminal 1 is provided in the scheduling reference information based on the following policy. Specifically, in the policy, the scheduling reference information may indicate that the base station 1 attempts to use radio resources that other base stations have not scheduled to the terminals they serve. For example, FIG. 5 illustrates that a base station at a different RAT is a co-site base station according to another embodiment of the present invention.

(Scheduled diagram in the case of base station 1 and base station Γ co-site, base station 2 and base station 2' co-site), wherein the coverage ranges of base stations of different RATs overlap each other. As shown in FIG. 5, for example, RATI and RAT2 may be an LTE system and a UTRA system, respectively, where base station 1 and base station 2 may be LTE base stations.

(eNodeB), the base station Γ and the base station 2' may be WCDMA base stations. According to the embodiment of the present invention, the radio resource management device 510 can use the radio resources of time, frequency, space, power, codeword, and the like to perform unified coordinated scheduling between base stations of different RATs, so as to more effectively improve the entire network. System performance. Specifically, if the load of the base station is relatively light (for example, only a small frequency resource of 5 MHz bandwidth is used), and the load of the base station 1 and the base station 2 is heavy, when the base station 1 needs to schedule the new edge terminal 1 In the case of radio resources, the base station 1 may have been unable to coordinate with the base station 2 for internal resources in the same RAT system. At this time, the scheduling reference information for the terminal 1 sent by the RRC device 510 to the base station 1 may instruct the base station 1 to schedule the RAT2 (UTRA)-specific frequency resource that the base station Γ has not scheduled for the terminal it serves to be scheduled to be served by the base station 1. The terminal 1 is such that the base station 1 employing the RATI can utilize the idle frequency resource of the base station 采用 employing RAT2. In addition, in this scenario, other radio resources other than frequency resources may also be used for coordinated scheduling between base stations. Although the above uses a co-site base station as an example to illustrate that one base station can attempt to schedule radio resources of other RAT base stations, it can be understood that similar coordinated scheduling can also be performed if two base stations are not co-sited.

In step S440, the radio resource management device may transmit the generated scheduling reference information to the base station 1.

At step S450, the base station 1 can generate a scheduling result based on the scheduling reference information received from the radio resource management device. For example, the base station 1 can generate a scheduling result by referring to the information of the radio resource recommended for the terminal 1 included in the scheduling reference information. It should be noted that the scheduling results can follow the recommendations in the scheduling reference information as much as possible.

Taking the LTE/LTE-A system as an example, if the PRB number included in the scheduling reference information is 1-5 (assuming that the total number of PRBs corresponding to the system bandwidth is 10), gp, the RRC device recommends using No. 1-5. PRB, then the eNodeB1 allocates the PRB to the UE1 according to the channel condition and the traffic volume (that is, in the process of generating the scheduling result), the PRB of the 1-5th should be selected as much as possible, thereby avoiding the uplink and downlink. Interference to UEs of neighboring cells. However, if the eNodeB1 can only select the PRBs of numbers 6-10, that is, the PRBs that the neighboring cell eNodeBs have scheduled for its UE, the bay ijeNodeB1 should not exceed the scheduling reference information when assigning the transmit power (downlink) to the UE1. The recommended transmit power value is used to reduce the downlink interference. When the eNodeB1 performs uplink power control on the UE1, the recommended transmit power value in the scheduling reference information should be exceeded as much as possible to reduce the uplink interference. In addition, for example, the eNodeB1 can use the multi-point cooperation set suggested in the scheduling reference information as much as possible without using a multi-point cooperation node that interferes with the UE of the neighboring cell to reduce interference on the uplink and downlink. The above is only given for the LTE/LTE-A system. In fact, similar processing can be performed for any other radio resources in any other RAT system to avoid the base station being the terminal. Scheduling radio resources that a plurality of base stations have scheduled to the respective served terminals.

In step S460, the base station 1 can transmit the scheduling result to the terminal 1. This step is similar to step S350 of the figure.

Through the embodiment shown in FIG. 4, the radio resource management device may send scheduling reference information to the station based on the request of the base station, so that the base station can obtain the radio resource suggested by the radio resource management device in time or obtain other base stations before scheduling. Information on the scheduling situation.

FIG. 6 illustrates an exemplary flow map for wireless resource scheduling in accordance with another embodiment of the present invention. The method shown in Fig. 6 relates to a scenario in which a radio resource management device actively transmits a scheduling reference message to the base station 1.

In step S610, the base station 1 and the base station 2 can respectively send scheduling information to the radio resource management device. This step is similar to step S310 in Fig. 3.

In step S620, the radio resource management device may extract, from the received scheduling information, specific radio resource information that may need to be referred to when the station 1 schedules radio resources. Alternatively, for example, the specific radio resource information may be information about radio resources scheduled by the neighboring base station 2 of the base station 1 for the scheduled terminal 2 adjacent to the station 1 served by the station 1.

In step S630, the radio resource management device may include the extracted radio resource information into the scheduling reference information.

In step S640, the radio resource management device may transmit scheduling reference information to the base station 1.
