Description
Technical Field
The present invention relates to the field of wireless relay communication, and in particular, to a method for managing relay configuration information and a relay station.
Background
With the continuous development of communication technology, the requirement for the access rate of the communication system is also continuously increased, and in order to meet the requirement for the access rate, the communication system adopting the broadband wireless access mode is more and more emphasized by people.
As can be seen from the theory of wireless communication, the higher the transmission frequency, the faster the radio wave attenuates with distance. Some existing communication systems have a relatively high operating frequency, so that the coverage area of a Base Station (BS) is very limited. For this reason, some standardization organizations are building standards for multi-hop wireless relay communication systems so that the systems can support Mobile Stations (MSs) based on the existing standards to communicate with a Base Station (BS) through 1 or more Relay Stations (RSs).
In an existing broadband wireless access wireless system, a relay station may be divided into a transparent relay station (non-transparent RS) and a non-transparent relay station (transparent RS). The non-transparent relay station transmits a downlink frame-start preamble (DL frame-start preamble), a Frame Control Header (FCH), a MAP messages (MAP messages), and a channel description message, wherein the channel description message is a downlink channel description message (DCD) or an uplink channel description message (UCD).
The transparent relay station does not transmit a downlink frame-start preamble (DL frame-start preamble), a Frame Control Header (FCH), a MAP messages (MAP messages), and a channel description message (including a DCD message and a UCD message).
When the inventor implements the invention, the inventor finds that the existing relay station has the following defects: in the prior art, each relay station only supports one working mode, namely, a transparent mode or a non-transparent mode, the working mode is configured when the relay is manufactured, and negotiation and modification cannot be carried out during the use process.

Detailed Description
The present invention will now be described in detail in preferred embodiments with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating an embodiment of a method for managing relay configuration information according to the present invention. The method comprises the following steps:
step S10, in the process of accessing the relay station into the network or after the process, determining a working mode supported by the relay station, wherein the working mode comprises at least two of a transparent mode, a non-transparent mode, a transparent and non-transparent coexisting mode;
step S12, configuring the determined operation mode as the operation mode adopted by the relay station.
Specifically, the relay station can support two functions of a transparent mode and a non-transparent mode, and only one working mode can be supported at the same time. During the network access process of the relay station, the operation mode adopted by the relay station can be configured in various ways.
Or, after the relay station completes network access, the relay station may reconfigure an operating mode adopted by the relay station under the trigger of a specific trigger event. For example, the mode of operation now used by the relay station may be switched to another mode of operation it supports, e.g., from a transparent mode to a non-transparent mode.
The process of configuring or reconfiguring the working mode adopted by the relay station may be implemented by the relay station negotiating with its associated base station, or by the base station performing assignment, or by the relay station selecting itself, or the like.
For example, the relay station may unilaterally select one of its supported operating modes as its employed operating mode and inform the base station associated with the relay station through an indication message.
Or, the base station unilaterally selects a working mode for the relay station, and informs the relay station through an indication message, and indicates the relay station to be configured or reconfigured into the working mode selected by the base station.
Or, the relay station negotiates with the base station, and determines the working mode adopted by the relay station for the relay station through a negotiation message between the relay station and the base station.
Wherein the step of configuring or reconfiguring the working mode adopted by the relay station is performed in a capability negotiation subprocess, a registration subprocess or a configuration subprocess of the relay station accessing the network; or in a reconfiguration sub-process after the relay station accesses the network. Those skilled in the art will appreciate that the configuration or reconfiguration process may also be performed in other sub-processes during the relay station accessing the network. Likewise, the configuration or reconfiguration process may be performed at any time after the relay station access network process is completed.
The following describes a process for determining an operation mode to be adopted by the relay station by using a specific embodiment:
the first embodiment is as follows:
in the capability negotiation subprocess of the network access process, when the relay station and the base station perform the basic capability negotiation process, the determination of the working mode (transparent or/and non-transparent mode) adopted by the relay station may be performed, which is specifically as follows:
the relay station firstly sends a basic capability request (SBC-REQ) message to the base station, where the SBC-REQ message carries indication information of a working mode supported by the relay station.
After receiving the SBC-REQ message of the relay station, the base station knows the basic capability of the working mode supported by the relay station and replies a basic capability response (SBC-RSP) message to the relay station so as to determine the type of the working mode adopted by the relay station.
In the implementation application, in the SBC-REQ message or the SBC-RSP message, the supported operation mode may be represented by two bits or three bits in a Type Length Value (TLV).
For example, in one definition, two bits (Bit1Bit0) may be used to indicate the operation mode supported or adopted by the relay station, as shown in the TLV table in table 1 below, where the first Bit (Bit0) is used to indicate whether the transparent mode is supported, for example, a value of 1 indicates that the transparent mode is supported, and a value of 0 indicates that the transparent mode is not supported; the second Bit (Bit 1) is used to indicate whether the non-transparent mode is supported, for example, if the value is 1, the non-transparent mode is supported, and if the value is 0, the non-transparent mode is not supported. In a specific application, for example, when the value of the two bits (Bit1Bit0) in the SBC-REQ message is "11", it indicates that the relay station has the capability of supporting the transparent mode and also has the capability of supporting the non-transparent mode, and it can operate in one of the operation modes at the same time. When the base station receives the SBC-REQ message, it knows the capability of the working mode of the relay station according to the value of the two bits, and selects one of the working modes as the working mode used by the relay station according to the requirement, and notifies the relay station in the SBC-RSP message, for example, if the working mode selected by the base station for the relay station is a transparent mode, the base station sets the value of the two bits (Bit1Bit0) to "01" in the SBC-RSP message; or if the operation mode selected by the base station for the relay station is the non-transparent mode, the base station sets the value of the two bits (Bit1Bit0) to "10" in the SBC-RSP message. After receiving the SBC-RSP message, the relay station determines the type of the working mode required by the relay station according to the value of two bits in the SBC-RSP message. This completes the negotiation process for configuring the operation mode. It can be understood that, when the two bits (Bit1Bit0) in the SBC-REQ message of the relay station have other values, the negotiation process is similar to this, for example, when the two bits (Bit1Bit0) in the SBC-REQ message of the relay station take values of "01", then the two bits in the reply SBC-RSP message of the base station also take values of "01"; or, when the two bits (Bit1Bit0) in the SBC-REQ message of the relay station take values of "10", the two bits in the reply SBC-RSP message of the base station take values of "10" as well; the detailed process is not described herein.
TABLE 1
Three bits (Bit2Bit1Bit0) may also be used to indicate the working mode supported or adopted by the relay station, as shown in the TLV table in table 2 below, where a first Bit (Bit0) is used to indicate whether the transparent mode is supported, for example, a value of 1 indicates that the transparent mode is supported, and a value of 0 indicates that the transparent mode is not supported; a second Bit (Bit 1) is used to indicate whether the non-transparent mode is supported, for example, if the value is 1, the non-transparent mode is supported, and if the value is 0, the non-transparent mode is not supported; the third Bit (Bit 2) is used to indicate whether the transparent mode and the non-transparent mode are simultaneously supported, for example, if the value is 1, it indicates that the transparent mode and the non-transparent mode are simultaneously supported, and if the value is 0, it indicates that the transparent mode and the non-transparent mode are not simultaneously supported. The biggest difference compared to table 1 is that the relay station, which indicates the supported operation capability in this way, has the capability to operate in both transparent and non-transparent modes at the same time.
For example, if the three-Bit (Bit2Bit1Bit0) value in the SBC-REQ message is "111", it indicates that the relay station has the capability of supporting the transparent mode and the capability of supporting the non-transparent mode, and also has the capability of supporting both the transparent mode and the non-transparent mode. When the base station receives the SBC-REQ message, it knows the capability of the working mode of the relay station according to the value of the three bits, and selects one of the working modes as the working mode used by the relay station according to the requirement, and notifies the relay station in the SBC-RSP message, for example, if the working mode selected by the base station for the relay station is the transparent mode, the base station sets the value of the three bits (Bit2Bit1Bit0) to "001" in the SBC-RSP message; or if the operation mode selected by the base station for the relay station is the non-transparent mode, the base station sets the value of the three bits (Bit2Bit1Bit0) to "010" in the SBC-RSP message; or if the operation mode selected by the bs for the rs is to adopt both transparent mode and non-transparent mode, the bs sets the value of the three bits (Bit2Bit1Bit0) to "100" in the SBC-RSP message. After receiving the SBC-RSP message, the relay station determines the type of the working mode required by the relay station according to the value of three bits in the SBC-RSP message. This completes the negotiation process for configuring the operation mode. It can be understood that when the three-Bit (Bit2Bit1Bit0) value of the SBC-REQ message of the relay station is other value, the negotiation process is similar to this, for example, when the three-Bit value of the SBC-REQ message of the relay station is "001", the base station will take the value of "001" on the three-Bit of the SBC-RSP message; or when the three-bit value of the relay station in the SBC-REQ message is "010", the base station will take the value of "010" in the three-bit value of the SBC-RSP message; or when the three-bit value of the relay station in the SBC-REQ message is "011", the base station will take the value of "001" in the three-bit value of the SBC-RSP message, or may also take the value of "010". The detailed process is not described herein.
TABLE 2
Example two:
in the registration sub-process of the network access process, the determination of the working mode (transparent or non-transparent mode) adopted by the relay station may be performed, specifically as follows:
the relay station firstly sends a registration request (REG-REQ) message to the base station, where the message carries indication information of a working mode supported by the relay station.
After receiving the REG-REQ message of the relay station, the base station knows the basic capability of the working mode supported by the relay station and replies a registration response (REG-RSP) message to the relay station, wherein the message carries the information of the working mode type selected for the relay station. After receiving the RGE-RSP message, the relay station can determine the specific type of the working mode to be adopted according to the indication in the RGE-RSP message.
Also, the operation modes supported and adopted by the relay station can be expressed in two ways, which can be seen in the following tables 3 and 4:
TABLE 3
For example, the two-bit value in the REG-REQ message of the relay station may be: 11; 01; 10. then the two bit values in the REG-RSP message returned by the base station may correspond to: 01 or 10; 01; 10.
TABLE 4
For example, the three-bit value in the REG-REQ message of the relay station may be: 001; 010; 011; 111; the three bit values in the REG-RSP message returned by the base station may correspond to: 001; 010; 001 or 010; 100 or 001 or 010.
Further details of the negotiation between the relay station and the base station are similar to the procedures in the foregoing descriptions of table 1 and table 2, and are not described in detail here.
Example three:
in a network access procedure, for example, in a configuration sub-procedure, the base station may notify the relay station of performing transparent mode configuration by sending a relay link channel description (RCD) message. In the message, the indication information of the working mode selected by the base station for the relay station is carried;
after receiving the message, the relay station confirms the working mode assigned by the base station, and replies a multi-hop relay general Acknowledgement (MR _ general-ACK) message to the base station to confirm the adopted working mode to the base station. The RCD message may be sent by the base station to all relay stations through a broadcast Connection ID (CID), or sent to one relay station through a primary CID.
This way the base station performs a procedure to assign a specific operation mode to the relay station.
Also, in the TLV of the message, two ways may be employed to indicate the mode of operation supported or employed by the relay station. See table 5.
TABLE 5
[0061]
In a specific application, the base station may indicate the selected operation type for the relay station by setting the value of the two bits (Bit1Bit0) in the RCD message, for example, if the two bits are "01", it indicates that the selected operation mode for the relay station is a non-transparent mode; if the two bits are "10", it indicates that the operation mode selected for the relay station is the transparent mode.
Similarly, the base station may indicate in the RCD message that the operation type is selected for the relay station by setting the three-Bit (Bit2Bit1Bit0) value, e.g., if the three-Bit is "001", it indicates that the operation mode selected for the relay station is the non-transparent mode; if the three bits are '010', the working mode selected for the relay station is a transparent mode; if the three bits are "100", the operation mode selected for the relay station is the transparent mode and the non-transparent mode.
Example four:
in a configuration subprocess of a network access process, a relay station sends a relay station configuration recommendation (RS _ configuration-RCM) message to a base station, wherein the RS _ configuration-RCM message carries a working mode (transparent or/and non-transparent mode) supported by the relay station;
after receiving the relay station configuration recommendation message, the base station confirms the working mode thereof, and replies a relay station configuration request (RS _ configuration-REQ) message to the relay station. After the negotiation, the relay station may adopt the operation mode determined by the base station.
In the Configuration _ para _ type item in the message, a bit (e.g., b6) is added to indicate that the message carries the operating mode information supported by the relay station. The specific supported operating mode types may be indicated by an additional (Bit1Bit0) or three bits (Bit2Bit1Bit 0).
The format of an RS _ Config-RCM message is shown in table 6 below, and the format of an RS _ Config-REQ message is shown in table 7 below.
TABLE 6
TABLE 7
[0073]
In the above negotiation process, the details of indicating the operation mode by using the two-bit or three-bit value are similar to those described in table 1 or table 2, and are not described in detail here.
It should be noted that after the network access procedure is completed, the relay station may reconfigure the operation mode of the relay station under the trigger of a specific trigger event, for example, by sending a relay station configuration recommendation (RS _ configuration-RCM) message to the base station, so as to reconfigure the operation mode, for example, switch the operation mode being used to another operation mode. The specific type of switched operating mode may be indicated using two bits (Bit1Bit0) or three bits (Bit2Bit1Bit0) in the two tables.
Example five:
in a configuration subprocess of a network access process, a relay station sends a relay station mode configuration Request (RS _ configuration-REQ) message to a base station, where the RS _ configuration-REQ message carries working mode information (transparent or/and non-transparent modes) supported by the relay station;
after receiving the relay station mode configuration, the base station confirms the operation mode therein, for example, a specific type of an operation mode may be selected for the relay station, and replies a relay station mode configuration reply (RS mode _ configuration-RSP) message to the relay station. The relay station receives the message and then adopts the working mode selected by the base station.
The specific supported operating mode types may be indicated by an additional (Bit1Bit0) or three bits (Bit2Bit1Bit 0).
For example, the following table 8 shows a format of an RS mode _ Config-REQ message, and table 9 shows a format of an RS mode _ Config-RSP message.
TABLE 8
TABLE 9
In the above negotiation process, the details of indicating the operation mode by using the two-bit or three-bit value are similar to those described in table 1 or table 2, and are not described in detail here.
It should be noted that, after the network access procedure is completed, the relay station may reconfigure the working mode of the RS under the trigger of a specific trigger event, and perform reconfiguration of the working mode by sending a relay station mode configuration Request (RS _ configuration-REQ) message to the base station, for example, switching the working mode being used to another working mode. The specific type of switched operating mode may be indicated using two bits (Bit1Bit0) or three bits (Bit2Bit1Bit0) in the two tables.
In the above two procedures, the RS mode configuration Request (RS _ configuration _ REQ) message may also be initiated by the base station, and the relay station confirms the operating mode thereof after receiving the message, and replies a RS mode configuration reply (RS mode configuration _ response, RS mode _ configuration _ RSP) message to the base station.
In a specific embodiment, table 10 shows another RS _ Config-REQ message format, and table 11 shows another RS mode _ Config-RSP message format, where:
in a Configuration parameter option (Configuration _ para _ type) item in the two messages, one bit is used to indicate that the message carries the operating mode information supported by the relay station that needs to be configured or the operating mode information supported by the relay station that needs to be reconfigured, for example, when the value is 1, the message carries the operating mode information that needs to be configured, and when the value is 0, the message carries the operating mode information that needs to be reconfigured. The specific operation mode types (e.g., transparent, non-transparent, and non-transparent) may be indicated by another (Bit1Bit0) or three bits (Bit2Bit1Bit 0). The indication is similar to the description of table 1 or table 2, and is not detailed here.
[0092] TABLE 11
Example six:
in the network access process, the base station may specify a specific operation mode of the relay station configuration by transmitting a relay station configuration command (RS _ configuration-CMD) message to the relay station; or after the network access is completed, under the trigger of a trigger event, the base station sends an RS _ Config-CMD message to the relay station to inform the relay station of reconfiguring a specific operating mode, for example, switching from a transparent mode to a non-transparent mode.
The relay station receives the message, confirms the message and replies an MR _ Generic-ACK message to the base station.
In a specific implementation, the specific type of the operation mode designated by the base station may be represented by different Bit values in the TLV of the message, and no specific identifier is required to represent the operation mode of the configuration or reconfiguration relay station, and similarly to the foregoing, two bits (Bit1Bit0) or three bits (Bit2Bit1Bit0) may be used to represent the specific type of the operation mode, and table 12 below shows a TLV format:
TABLE 12
During or after the network access process, for example, two bits (Bit1Bit0) in the TLV of the message of the relay station may take the following values: "01", "10", wherein "01" indicates that the non-transparent mode is supported; "10" indicates that the transparent mode is supported.
Or, three bits (Bit2Bit1Bit0) in the TLV of the message of the relay station may take the following values: "001", "010", or "100", wherein "001" indicates that non-transparent mode is supported; "010" indicates that the transparent mode is supported; "100" indicates that both transparent and non-transparent modes can be supported at the same time;
it should be noted that, in other embodiments, a specific identifier may also be used to describe the operation mode process of configuring or reconfiguring the relay station, and table 13 below shows such a TLV format:
watch 13
Wherein, the first Bit (Bit0) is used to indicate whether to perform configuration during network access or perform reconfiguration after network access is completed (i.e. switching process of working mode of relay station); for example, when the value of the Bit0 is 0, the configuration in the network access process is represented, and when the value of the Bit0 is 1, the reconfiguration after the network access is completed is represented; it should be noted that the above-mentioned arrangements are only examples, but not limitations, and those skilled in the art can understand them.
Then during the network access procedure, the three Bit value (Bit2Bit1Bit0) in the TLV of the relay's message may take "010", "100", or "110", for example, where "010" indicates that the non-transparent mode is supported; "100" indicates that the transparent mode is supported; "110" indicates support for transparent mode and non-transparent mode; during the reconfiguration process, the value in the TLV of the message of the relay station may take "011", "101" or "111", wherein "011" indicates the reconfiguration to the non-transparent mode; "101" indicates reconfiguration to transparent mode; "111" indicates reconfiguration to transparent mode and non-transparent mode.
The above describes, by way of example, a process of configuring an operating mode of a relay station in a network access process of the relay station (for example, the process may be negotiated between the relay station and a base station, selected by the relay station, or specified by the base station), and describes, at the same time, a process of reconfiguring an operating mode of the relay station after the network access of the relay station is completed (for example, the process may be negotiated between the relay station and the base station, selected by the relay station, or specified by the base station).
The above reconfiguration process is generally triggered by a specific trigger event, and the relay station or the base station reconfigures the operating mode adopted by the relay station according to a predetermined policy. For example, it may be:
when the users served by the relay station are judged to be within the coverage range of the base station, the working mode adopted by the relay station is reconfigured to be a transparent mode, for example, the working mode can be switched from a non-transparent mode to a transparent mode, so as to reduce the signaling overhead of the relay station to the mobile station, save the system energy overhead and the like; or,
when the user served by the relay station is judged to be out of the coverage range of the base station and in the coverage range of the relay station, the working mode adopted by the relay station is reconfigured to be a non-transparent mode, for example, the transparent mode can be switched to be the non-transparent mode; or
When the relay station is judged to move from the edge of the coverage area of the base station to the coverage area of the base station, the working mode adopted by the relay station is a reconfiguration transparent mode, for example, the working mode can be switched from a non-transparent mode to a transparent mode, so that unnecessary signaling overhead and system energy overhead are reduced, and the service quality can be ensured; and otherwise, the working mode adopted by the relay station is reconfigured to be a non-transparent mode.
It should be noted that the specific trigger event and the predetermined policy corresponding to the specific trigger event are only examples, and those skilled in the art will understand that there are other trigger events that may cause the operation mode reconfiguration process of the relay station, for example, when the load or channel quality of the system changes beyond a certain degree, the operation mode reconfiguration process of the relay station may also be caused, which is not exhaustive here.
Accordingly, the present invention provides a relay station, as shown in fig. 2, where the relay station 1 includes:
an operation mode determining unit 12, configured to determine an operation mode supported by the relay station, where the operation mode includes at least two of a transparent mode, a non-transparent mode, and a transparent and non-transparent coexistence mode;
a configuration unit 14, configured to configure the operation mode determined by the operation mode determining unit 12 as the operation mode adopted by the relay station. The method and the device are used for determining the working mode adopted by the relay station during or after the relay station accesses the network, wherein the working mode comprises a transparent mode or/and a non-transparent mode, namely the relay station can be configured into the transparent mode, or into the non-transparent mode, or into a mode supporting transparent and non-transparent coexistence.
A trigger event detecting unit 10, configured to instruct the operation mode determining unit 12 to re-determine an operation mode according to a predetermined policy when a predetermined trigger event is detected, and configure the operation mode to be used by the relay station.
In the trigger event detection unit 10:
the trigger event may be: when the users served by the relay station are all within the coverage range of the base station, the predetermined policy is: reconfiguring the working mode adopted by the relay station into a transparent mode, for example, switching the relay station from an original non-transparent mode to the transparent mode; or
The trigger event may be: when the user served by the relay station is out of the coverage of the base station and in the coverage of the relay station, the predetermined policy is: reconfiguring the working mode adopted by the relay station into a non-transparent mode; or
