This application is a continuation application of U.S. patent application Ser. No. 15/428,676, filed Feb. 9, 2017, in the U.S. Patent and Trademark Office, which application is a continuation application of U.S. patent application Ser. No. 13/857,266, filed Apr. 5, 2013, which is a divisional of U.S. patent application Ser. No. 13/002,290, filed Dec. 30, 2010, which is a national stage of International Application No. PCT/JP2009/062042, filed Jul. 1, 2009, claiming priority based on Japanese Patent Application No. 2008-172798, filed Jul. 1, 2008, the contents of all of which are incorporated herein by reference in their entirety.
An MBSFN area (range in which multiple base stations are synchronized to perform the same MBSFN transmission) defined by LTE is composed of the following two types of cells (Non-Patent Document 1):
Cell in which a base station performs an MBSFN transmission (MBSFN transmitting and advertising cell: hereinafter termed an “MBSFN service cell”); and
Cell in which a base station does not contribute to an MBSFN transmission, but performs only a unicast or single-cell/multicast transmission is performed (MBSFN area reserved cell: hereinafter termed a “reserved cell”).
The MBSFN outage probability is determined based on the requirement condition for the quality of MBSFN that is actually transmitted, and, based on a volume of PTP (Point To Point) traffic in the reserved cell, the following are determined:
MBSFN MCS satisfying an outage probability; and
Transmission power, or the maximum of transmission power, for MBSFN subframes in a reserved cell (percent of MBSFN power) Note that PTP, which is equivalent to unicast, means a dedicated communication scheme or a service by the dedicated communication scheme.
the target value of MBSFN outage probability is 10%, and MCS is 2, then, it is determined by the table in FIG. 25 that the transmission power, or the maximum of the transmission power, of a base station in the reserved cell is 10% of the maximum transmission power of MBSFN.
3GPP TSG RAN WG2, Stage 2 specification 36.300 v8 3.0 http://www.3gpp.org/ftp/Spec s/html-info/36300.htm
It is an object of the present invention to provide a radio communication system, a base station apparatus, a Multi-cell/Multicast Coordination Entity (MCE), a radio communication method, and a program that allow setting to be optimally determined from the viewpoint of PTP (point-to-point) system throughput in an MBSFN area while satisfying a requirement for a MBSFN quality.
a scrambling code may be output. More specifically,
information on the subframes that may be used (reserved) for MBSFN is defined as “mbsfn-Subframe Configuration” (configuration of mbsfn-subframe),
information on MBSFN frames (frame number, frame period, etc.) is defined as “radio Frame Allocation” (allocation of radio frame), and
information on the number of MBSFN subframes is defined as “subframe Allocation” (sub-frame allocation).
At the time MBSFN subframes are transmitted, a base station (eNodeB: called “eNB”) in a reserved cell reduces the transmission power and performs unicast transmission, does not perform unicast transmission at all, or performs single-cell/multicast transmission for a terminal (User Equipment: called “UE”) to reduce interference to the MBSFN service cells for improving the MBSFN quality. Although not limited thereto, it is assumed in the embodiments described below that the cell type (whether the cell is an MBSFN service cell or a reserved cell) was already notified from MCE to eNB, for example, when MBSFN was initialized. The cell type is notified again to eNB when the cell type is changed or at a periodic interval. The cell type may be notified either with the transmission parameters, which will be described later, or separately. In the description of the embodiment below, the description of the cell type notification processing is omitted.
The MBSFN configuration information generated by the MCE 103 includes the following:
Which eNB performs MBSFN; and
In which order the services are offered if there are multiple MBSFN service candidates.
The MBSFN control information notified from the MCE 103 to the eNB 104 includes the following:
MCS of MBSFN;
Number of MBSFN subframes;
Positions of MBSFN subframes;
Positions of MBSFN frames;
Period of MBSFN frame;
Reference signal of MBSFN;
Scrambling code of MBSFN;
Transmission power or maximum of transmission power in a reserved cell;
Frequency usage rate in a reserved cell; and
Frequency band (resource) in a reserved cell.
The multicast related information includes the following:
Number of UEs that receive/request (want to receive) MBMS/MBSFN for each content; and
MBMS/MBSFN error rate.
The unicast related information includes, for example, the following:
Number of UEs in active state, that is, in RRC_CONNECTED state (state in which a radio link is established);
Number of UEs that are performing VoIP (Voice over IP); and
PTP traffic volume.
As described above, the MCE determines the transmission parameter for MBSFN transmission or unicast transmission in an MBSFN area. The MBSFN transmission parameter includes, for example, as follows:
MSAP (Multicast channel Subframe Allocation Pattern) indicating micro/macro level allocation;
MCS; and
Transmission power or the maximum of transmission power of MBSFN transmission.
The unicast transmission parameter includes, for example, as follows:
Transmission power or the maximum of transmission power; and
Usable frequency band (resource) in a MBSFN subframe in a reserved cell in an MBSFN area.
FIG. 2 is a sequence diagram showing a control procedure used in the embodiment shown in FIG. 1. Base stations eNB1-eNBn, each serving an MBSFN service cell, collect (measurement) information, defined in specifications in advance, or information requested by the MCE, and reports the measurement result to the MCE (“eNB Measurement Report” in FIG. 2).
Based on the measurement report (eNB Measurement Report) received from the base stations eNB1-eNBn, the MCE checks if the MBSFN (or MBSFN and unicast) transmission parameter in the MBSFN area needs to be reset (“Reconfiguration decision” in FIG. 2: decide to reset the parameter).
If it is determined by the MCE that the MBSFN transmission parameter needs to be reset, the MCE actually resets the MBSFN transmission parameter (“MBSFN setting update” in FIG. 2: update the MBSFN setting) and transmits a reconfiguration request to the eBMSC via the E-MBMS GW (“Reconfiguration Request” in FIG. 2: request for reset).
In response to the request for reconfiguration (Reconfiguration Request), the eBMSC reconfigures the transmission parameter using the same procedure as the MBSFN transmission parameter configuration procedure used when MBSFN is started (“MBSFN reconfiguration” in FIG. 2). Note that the parameter may be reconfigured not only by an absolute value but also by a relative value such as a difference or a rate.
As shown in FIG. 2, the information included in the eNB measurement report includes, for example, as follows.
Volume of PTP traffic in unicast transmission;
Number of active UEs performing unicast transmission;
Number of VoIP UEs;
Number of UEs receiving MBSFN;
Number of UEs requesting MBSFN; and
MBSFN quality (error rate, etc.) (Error rate of MBSFN service).
Base stations eNB 1-eNBm each serving an MBSFN service cell and base stations eNBm+1-eNBn each serving a reserved cell collect (measurement) the information defined by specifications in advance or the information specified by MCE, and report the result to the MCE (“eNB Measurement Report” in FIG. 4).
Based on the eNB measurement report (eNB Measurement Report), the MCE checks if the MBSFN transmission parameter needs to be reset (“Reconfiguration decision” in FIG. 4).
If it is determined by the MCE that the MBSFN area transmission parameter must be reset, the MCE actually resets the MBSFN area transmission parameters and transmits a reconfiguration request to the eBMSC via the E-MBMS GW (“Reconfiguration Request” in FIG. 4n ).
As shown in FIG. 4, an example of the information included in the eNB measurement report notified by eNB1-eNBm, each serving an MBSFN service cell, is as follows:
Number of UEs receiving MBSFN (or information that makes it possible to estimate the number of the UEs on the MCE side); and
Number of UEs requesting MBSFN (or information that makes it possible to estimate the number of the UEs on the MCE side) error rate, etc.) (Error rate of MBSFN service).
On the other hand, the eNB Measurement Report information notified by eNBm+1-eNBn each serving a reserved cell includes, for example, as follows:
Number of active UEs performing unicast transmission; and
Number of VoIP UEs.
In the description below, it is assumed that the MBSFN area is composed only of MBSFN service cells (no reserved cell), and the transmission parameter that is controlled is as follows:
MBSFN MCS.
First, the PTP traffic volume is measured for each cell in the MBSFN area and, as shown in FIGS. 7A and 7B, the following is calculated as a representative value:
Average value; or
Maximum value (or minimum value).
FIG. 11 and FIGS. 12A-12I are diagrams showing the control based on the concept of the present embodiment described with reference to FIG. 6. In those figures, it is assumed that the MBSFN area is composed of MBSFN service cells and reserved cells. FIG. 12B to FIG. 12E show the reception quality (Rx quality) of the cells shown in FIG. 11 at times t=t0−t3. FIG. 12F-FIG. 12I show the control performed by the MCE at times t=t0−t3 in FIG. 12B-FIG. 12E.
In a first exemplary embodiment of the present invention, based on
PTP traffic volume (load) of reserved cells and
Target value of MBSFN outage probability, the following are set so that the total system throughput of the MBSFN area is maximized:
Transmission power or maximum of transmission power for MBSFN subframes in a reserved cell.
System_throughput = ∑ S ⁢ Min ⁡ ( generated_traffic , acceptable_traffic ) ⁢ ⁢ … ⁢ ⁢ MBSFN ⁢ ⁢ Service ⁢ ⁢ cell + ∑ R ⁢ Min ⁡ ( generated_traffic , acceptable_traffic ) ⁢ ⁢ … ⁢ ⁢ Reserved ⁢ ⁢ cell ( 1 )
“Acceptable traffic” is a function of the number of MBSFN subframes, MCS, and the transmission power or the maximum of the transmission power in the reserved cells. If MBSFN subframes are not always included in every frame, the MBSFN frame period is also one of the variables.
First, the MBSFN control unit 202 of the base station (eNB) checks if the MBSFN control information has been received from the MCE, that is, if the base station belongs to an MBSFN area (S102).
If the base station does not belong to an MBSFN area (No in S102), the usual unicast transmission is assumed and the unicast signal transmission unit 205 performs only the unicast transmission (S107).
At a specified point of time t, the system throughput estimation value calculation unit 210 of the MCE first creates a table, such as the one shown in FIG. 18, indicating the relation among
MCS and number of MBSFN subframes; and
Transmission power or the maximum transmission power used in a reserved cell,
Now, it is assumed that the target value of the MBSFN outage probability is 10%. In this case, in FIG. 18, the candidates for a combination of the transmission power or the maximum of the transmission power for the MBSFN subframes in a reserved cell, MBSFN MCS, and the number of MBSFN subframes, which satisfy the outage probability=10%, are the following three.
([Reserved cell power],[MBSFN MCS]/[# of subframes])=(50%,1/8),(10%,2/7),(0%,10/1)
Based on the time-average value of the PTP traffic for the periods 5T, t=T0 to t=T4, because the control period of the MCE is 5T, the system throughput is calculated for each of the combinations of the above three using expression (1) and the combination is selected that achieves the maximum throughput.
In the embodiment described above, the average of the PTP traffic volumes reported by the eNBs belonging to MBSFN service cells or reserved cells is used. Instead of the average,
Representative value that is the largest or smallest at each time, or
Average of the center N values of the values reported by M eNBs (N<M)
In a second exemplary embodiment of the present invention, based on
PTP traffic volume (load) of reserved cells; and
Target value of MBSFN outage probability, the following are set so that the total system throughput of an MBSFN area is maximized:
FIG. 20 is a block diagram showing the configuration of the MCE in the second exemplary embodiment. The configuration of an eNB is the same as that of an eNB in the first exemplary embodiment and so the description is omitted here. In the description below, an MCE 301 is assumed to be connected to one E-MBMS GW and multiple eNBs. The MCE 301 comprises an average traffic calculation unit and a transmission mode control unit 303.
Finally, the transmission mode control unit 303 checks if the control time has arrived (S304) and, if the control time has arrived (Yes in S304), determines the MBSFN area transmission parameter, based on the PTP traffic volume index and the table, which is prepared in advance for each MBSFN outage probability (%) to indicate the relation among the PTP traffic volume, the MBSFN MCS, the number of MBSFN subframes, and the transmission power or the maximum of transmission power in reserved cells, and notifies the base stations about the result.
In the description below, it is assumed thateNBA1-A3 and eNBB1-B2 belong to the same MBSFN area and exchange information with the MCE,
The MCE prepares in advance a table, such as the one shown in FIG. 22, for use in mapping the PTP traffic volume to one of several levels (Low, Medium, and High in FIG. 22). If the average PTP traffic is larger than 0 but equal to or smaller than P1, the PTP traffic index is the value 0 indicating “Low”; if the average PTP traffic is larger than P1 but equal to or smaller than P2, the PTP traffic index is the value 1 indicating “Medium”; and if the average PTP traffic is larger than P2, the PTP traffic index is the value 2 indicating “High”.
