Description
Technical Field
The present invention relates to the field of mobile communication technologies, and in particular, to a method for sending multi-carrier configuration information and a method for allocating secondary carriers.
Background
In the related art, an 802.16m system is evolved based on an 802.16e system, the 802.16m system is a multi-carrier system based on Orthogonal Frequency Division Multiple Access (OFDMA) technology, a protocol architecture is shown in fig. 1, and a single Medium Access Control (MAC) entity controls a Physical layer (PHY) including a plurality of channels, for example, a channel 1 and a channel 2. Each channel may have a different bandwidth, for example, channel 1 may have a bandwidth of 5MHz, channel 2 may have a bandwidth of 10MHz, and channel N may have a bandwidth of 20MHz, and the channels may belong to contiguous or non-contiguous frequency bands.
The frame structure design in the 16m system adopts a three-layer structure of super frames, unit frames and sub frames, as shown in fig. 2. The wireless resource is divided into superframes (superframes) which are continuous in time, the time length of each SuperFrame is 20 milliseconds, each SuperFrame is composed of 4 frames (frames) with the time length of 5 milliseconds, and each Frame comprises 8 subframes (Sub frames, abbreviated as SFs). The Super Frame Header (SFH) is located in the first downlink subframe of each Super Frame, and may be further divided into a Primary Super Frame header (Primary SFH) and a Secondary Super Frame header (Secondary SFH) according to functions. In place, the superframe header is immediately followed by a preamble sequence (a-preamble for short).
There may be one or more Fully configured carriers (Fully configured carriers) in an 802.16m system, including all synchronous, broadcast, multicast, and unicast control information, information and parameters related to multi-carrier and other carrier operations; meanwhile, there may be one or more Partially configured carriers (Partially configured carriers) only used for downlink transmission, including all control channels supporting downlink transmission. The fully configured carrier may be used as a primary carrier or a secondary carrier of the terminal, and the partially configured carrier may only be used as a secondary carrier of the terminal. In a cell, each Mobile Station (MS) has only one primary carrier, which is used for interactive services and control information of all physical layers and media access control layers, and is mainly used for controlling operations of the MS, such as network access. There may or may not be one or more secondary carriers, which are carriers allocated to the MS for transmitting traffic by Base Station (BS) specific commands and rules. In addition, some control signaling supporting multi-carrier operation may also be sent on the secondary carrier.
For a terminal to access a multi-carrier system, two operation modes are specified as follows:
carrier aggregation: the terminal always keeps physical connection with the main carrier thereof and monitors the control information transmitted on the terminal;
and (3) carrier switching: through the indication information of the base station, the terminal can switch the physical connection from the main carrier to the auxiliary carrier; after connecting with the secondary carrier, the terminal need not maintain physical connection with its primary carrier.
It can be seen that, if a base station supports multi-carrier operation, that is, supports one or more fully configured carriers and partially configured carriers at the same time, a terminal supporting multi-carrier operation must acquire multi-carrier configuration information of the base station to perform communication under the base station. However, in the current 802.16m multi-carrier system, a technical scheme for how the terminal acquires the multi-carrier configuration information of the base station is not provided, so that the terminal cannot acquire the multi-carrier configuration information of the base station, and thus cannot perform multi-carrier communication under the base station.
Disclosure of Invention
In view of this, the present invention provides a method for sending multi-carrier configuration information and a method for allocating secondary carriers, so as to solve the problem that a terminal cannot perform multi-carrier communication in a base station because the terminal cannot acquire multi-carrier configuration information of the base station.
According to the invention, a method for transmitting multi-carrier configuration information is provided.
The method for transmitting the multi-carrier configuration information comprises the following steps: the base station transmits the multi-carrier configuration information of the base station to the terminal through a control channel and/or a management message.
According to another aspect of the present invention, a secondary carrier allocation method is provided.
The method for allocating the auxiliary carrier wave comprises the following steps: in the multi-carrier network access process of the terminal, or after the terminal follows the network access process of the single carrier wireless communication system to complete the initial network access, the terminal acquires the multi-carrier configuration information broadcasted by the base station; the terminal and the base station interact basic multi-carrier capability; the terminal and the base station interact specific multi-carrier capability, and the base station distributes auxiliary carriers for the terminal.
Through at least one scheme of the invention, the base station sends the multi-carrier configuration information of the base station to the terminal through the control channel and/or the management message, so that the terminal can acquire the multi-carrier configuration information of the base station, the problem that the terminal cannot carry out multi-carrier communication under the base station because the terminal cannot acquire the multi-carrier configuration information of the base station is solved, and the auxiliary carrier allocation in a multi-carrier system can be realized through the invention.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

Detailed Description
Overview of the function
For a base station supporting multi-carrier operation, a terminal supporting multi-carrier operation can perform multi-carrier communication under the base station only on the premise of acquiring multi-carrier configuration information of the base station, and in a multi-carrier wireless communication system, the base station needs to allocate an auxiliary carrier to the terminal. In the embodiment of the invention, the base station sends the multi-carrier configuration information of the base station to the terminal through the control channel and/or the management message, so that the terminal can acquire the multi-carrier configuration information of the base station. In addition, in the embodiment of the invention, in the multi-carrier network access process of the terminal or after the terminal completes the initial network access following the network access process of the single-carrier wireless passing system, the terminal and the base station interact the basic multi-carrier capability and the specific multi-carrier capability, and the base station distributes the auxiliary carrier for the terminal according to the basic multi-carrier capability and the specific multi-carrier capability of the terminal.
The embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
According to an embodiment of the present invention, a method for transmitting multi-carrier configuration information is provided, where the method is used for a base station to transmit multi-carrier configuration information of the base station to a terminal.
The method for sending the multi-carrier configuration information comprises the following steps: the base station transmits the multi-carrier configuration information of the base station to the terminal through a control channel and/or a management message.
In a specific implementation process, the sending, by the base station, the multi-carrier configuration information to the terminal through the control channel includes: the system parameters and system configuration information sent by the base station in the superframe header carry the multi-carrier configuration information of the base station; the base station sends the multi-carrier configuration information to the terminal through the management message, and the method comprises the following steps: the base station carries the multi-carrier configuration information in a management message containing the expanded system parameters and the system configuration information to be sent, or the base station takes the multi-carrier configuration information as a single management message to be sent in a broadcast/unicast mode.
Therefore, in the embodiment of the present invention, the base station may send the multi-carrier configuration information of the base station to the terminal by the following four methods:
the first sending method comprises the following steps: the system parameters and system configuration information sent by the base station in the superframe header carry the multi-carrier configuration information of the base station;
and a second sending method: the base station carries the multi-carrier configuration information of the base station in a management message containing expanded system parameters and system configuration information and sends the management message to the terminal;
and a third sending method: the base station carries the multi-carrier configuration information in the multi-carrier configuration message for broadcast transmission;
and a fourth sending method: in the method, the base station can actively send the multi-carrier configuration message to the terminal, or send the multi-carrier configuration message to the terminal when receiving the request message of the terminal.
The four methods described above are described below.
(one) sending method
When the sending method is adopted to send the multi-carrier configuration information of the base station to the terminal, the multi-carrier configuration information can be sent as a parameter item of a main super-frame header or a sub-packet of a secondary super-frame header.
Preferably, when the multi-carrier configuration information is sent as a sub-packet of the secondary superframe header, the multi-carrier configuration information may be sent as a sub-packet of the secondary superframe header, or may be sent by combining with a sub-packet including system parameters for network access/re-access/network discovery.
For a sub-packet containing multi-carrier configuration information, the transmission period may be transmitted according to a fixed period (i.e., a period predetermined by the base station and the terminal), or according to information indicating sub-packet scheduling in the broadcasted system information, in this case, the terminal may obtain the transmission period of the sub-packet containing multi-carrier configuration information from the broadcasted system information, so as to obtain the multi-carrier configuration information transmitted by the base station at the transmission time.
(II) Transmission method II
When the second transmission method is used to transmit the multi-carrier configuration information, the base station carries the multi-carrier configuration information in a management message containing the extended system parameters and the system configuration information and transmits the management message to the terminal, and specifically, the base station may transmit the management message containing the extended system parameters and the configuration information according to an indication of the system information (the base station may broadcast at a superframe header).
Specifically, the multi-carrier configuration information may be sent as an information element of a management message including the extended system parameter and the system configuration information, as a parameter item of the management message, or as a parameter item of the management message that is encoded.
In a specific implementation, in the first transmission method and the second transmission method, the sub-packets/information elements of the multi-carrier configuration information may adopt a format as shown in table 1.
TABLE 1
(III) Transmission method III
When the multi-carrier configuration information is sent by adopting the third sending mode, the base station carries the multi-carrier configuration information in a multi-carrier configuration message, and the multi-carrier configuration message is sent to the terminal in a broadcast mode as a management message.
In a specific implementation process, the base station may send the multi-carrier configuration message according to a preset fixed or variable period, where the preset fixed or variable period may be a value predetermined by the base station and the terminal, or the base station broadcasts the period in a superframe header;
preferably, the multi-carrier configuration message may be transmitted as an encoded item of the system configuration message.
(IV) transmitting method IV
In the fourth sending method, the base station carries the multi-carrier configuration information in a multi-carrier configuration message, and the multi-carrier configuration message is sent to the terminal as a management message in a unicast mode.
In the method, a base station can actively send the multi-carrier configuration message to a terminal; or the terminal sends a request message of the multi-carrier configuration information to the base station, and the base station sends the multi-carrier configuration information to the terminal as a response after receiving the request message of the terminal; in both of these modes, after receiving the multi-carrier configuration message sent by the base station, the terminal may send an acknowledgement message to the base station, indicating that the terminal has received the multi-carrier configuration message, and specifically, the content of the acknowledgement message includes but is not limited to: message type, transmission identification, coding item, etc.
In a specific implementation process, if the terminal sends the multi-carrier configuration request message, the terminal may set a timer and a counter, thresholds of the timer and the counter may be set according to specific applications, the terminal starts the timer and the counter when sending the request message, if the timer reaches the threshold, the terminal does not receive the multi-carrier configuration message sent by the base station, the counter adds 1, if the counter reaches the threshold, the terminal does not send the request message any more, at this time, if the terminal cannot acquire the multi-carrier configuration information of the base station, the terminal cannot perform multi-carrier operation temporarily, if the counter does not reach the threshold, the terminal resends the request message, and restarts the timer, and returns to the relay node to determine whether to receive the multi-carrier configuration message from the base station. If the terminal receives the multi-carrier configuration information before the timer and the counter reach the threshold, the terminal may perform multi-carrier related operations.
Specifically, the terminal may send the request message of the multi-carrier configuration information in the following two ways:
the first form: the method comprises the steps that a management message mode is adopted for sending, namely a terminal sends a request message to a base station, and the request message is used for requesting multi-carrier configuration information of the base station;
the second form: sending by adopting an MAC (media access control) head, wherein the MAC head only carries or mainly carries multi-carrier configuration request information; specifically, the MAC header may be a generic MAC header, a compressed MAC header, an extension header, or a MAC header dedicated to signaling in format.
If the base station is adopted to actively send the multi-carrier configuration message to the terminal, specifically, the base station can be provided with a timer and a counter, the threshold values of the timer and the counter can be set according to specific application, when the active multi-carrier configuration message is sent, the base station starts the timer and the counter, if the timer reaches the threshold value of the timer and the base station does not receive the confirmation information of the terminal, the counter is increased by 1, if the counter does not reach the threshold value of the counter, the base station resends the multi-carrier configuration message, simultaneously restarts the timer and continuously judges whether the confirmation information is received, if the counter reaches the threshold value of the counter, the base station does not send the multi-carrier configuration message any more, and the base station considers that the terminal cannot carry out multi-carrier operation. If the acknowledgement information of the terminal is received before the timer and the counter reach the threshold, the terminal is considered to be capable of multi-carrier related operation.
Specifically, the acknowledgement information sent by the terminal may take the following three forms:
the first form: sending the message by adopting a management message mode;
the second form: sending by using an MAC header, wherein the MAC header only carries or mainly carries confirmation information of the multi-carrier configuration message; the MAC header may be a generic MAC header, a compressed MAC header, an extended header, or a MAC header dedicated to signaling in format;
the third form: the indication is made by sending signaling on a feedback channel, which is a feedback channel that carries the channel quality of the terminal on the allocated or activated carrier (current carrier or primary carrier).
In a specific implementation process, in the third transmission method and the fourth transmission method, the format of the multicarrier configuration message may be as shown in table 2.
Table 2
In a specific implementation process, after the multi-carrier configuration information of the base station is sent by using any one of the four methods, if the terminal does not receive the multi-carrier configuration information of the base station when the base station allocates the secondary carrier for the terminal, the terminal may carry an indication that the multi-carrier configuration information is not received in the secondary carrier allocation response information, or send a multi-carrier configuration request message to the base station, and after receiving the indication or the request message, the base station sends a unicast multi-carrier configuration message to the terminal.
If the terminal has not received the multicarrier configuration information of the base station in the capability exchange and registration phase, the terminal may carry an indication that the multicarrier configuration information has not been received in the registration request message (the registration request message may specifically adopt the format shown in table 3), or send a unicast multicarrier configuration request message to the base station, and after receiving the indication/request message, the base station may carry the multicarrier configuration information in the registration response message (the registration response message may specifically adopt the format shown in table 4), or send a unicast multicarrier configuration message to the terminal.
Table 3
Table 4
In addition, in the embodiment of the present invention, when the base station is a neighboring cell broadcast message sent by a terminal under the base station, the base station may also carry multi-carrier configuration information of the neighboring cell base station in the neighboring cell broadcast message. The multi-carrier configuration parameter item of the neighboring cell base station in the neighboring cell broadcast message may be the same as or different from the sent multi-carrier configuration parameter item of the base station.
In addition, in the embodiment of the present invention, if the base station receives the request message of the multi-carrier configuration information of the terminal while sending the broadcast or unicast multi-carrier configuration message to the terminal, the base station ignores the message and still sends the message in the current manner.
In a specific implementation process, the content of the multi-carrier configuration information includes, but is not limited to, at least one of the following: the method comprises the following steps of configuring a multi-carrier mode, a physical serial number of one or more carriers configured by a base station, an uplink/downlink central frequency point value, an uplink/downlink carrier bandwidth, a carrier type (including full configuration or partial configuration), a duplex mode, a preamble sequence serial number, whether protection subcarrier operation is supported, protection subcarrier configuration information and the like.
The base station and the terminal may adopt one or more of the above four methods to transmit the multi-carrier configuration information as needed. The following description will be made by specific examples.
Example one
In this embodiment, the multicarrier configuration information of the base station is transmitted by the fourth transmission method, and the base station actively transmits the multicarrier configuration information to the terminal. Fig. 3 is a schematic diagram of a sending flow of the multi-carrier configuration information in this embodiment, and as shown in fig. 3, the step of actively sending the unicast multi-carrier configuration information to the terminal by the base station mainly includes the following steps:
Through the above processing, the unicast flow that the base station actively sends the multi-carrier configuration information can be realized.
Example two
In this embodiment, the base station transmits the multicarrier configuration information to the terminal in four directions by using the transmission method, and in this embodiment, the base station transmits the multicarrier configuration information after receiving the request message transmitted by the terminal.
Fig. 4 is a schematic diagram of a method for sending multi-carrier configuration information requested to be initiated by an MS in the embodiment, as shown in fig. 4, the method for sending multi-carrier configuration information requested to be initiated by an MS mainly includes the following steps:
step 401, the MS sends a request message of multi-carrier configuration information to the base station on an access carrier, and at the same time, starts a timer and a counter, and increments the counter by 1 every time the request message is sent;
step 403, after receiving the request message sent by the terminal, the base station sends a multi-carrier configuration message to the terminal in a unicast manner, where the multi-carrier configuration message carries multi-carrier configuration information of the base station, and the terminal receives the multi-carrier configuration message before the timer ends and stops the timer.
Step 405, after receiving the multi-carrier configuration message sent by the base station, the terminal sends a multi-carrier configuration confirmation message to the base station, and the process is ended.
Through the above processing, the unicast flow of the multicarrier configuration information requested by the terminal is realized.
EXAMPLE III
In this embodiment, the base station combines the second transmission method and the fourth transmission method to transmit its multi-carrier configuration information.
Fig. 5 is a flowchart illustrating the base station sending its multi-carrier configuration information to the terminal in this embodiment, and as shown in fig. 5, the base station sending its multi-carrier configuration information to the terminal mainly includes the following steps:
step 501: the base station carries the multi-carrier configuration information in the expanded system parameters and system configuration information of the full configuration carrier, and the terminal acquires the multi-carrier configuration information of the base station according to the indication of other system information;
step 503, the terminal needs the multi-carrier configuration information in the subsequent process, and if the terminal fails to acquire the multi-carrier configuration information in step 501, the terminal sends a request message of the multi-carrier configuration information to the base station to request the base station to unicast the multi-carrier configuration information.
In step 503, if the terminal receives the secondary carrier allocation message from the base station before not receiving the multi-carrier configuration information, the terminal may carry an indication that the multi-carrier configuration information is not received in the secondary carrier allocation response message, and the base station sends a unicast multi-carrier configuration message to the terminal when receiving the indication. Or, the terminal sends a multi-carrier configuration request message to the base station, and requests the base station to send the multi-carrier configuration message.
Example four
In this embodiment, the multicarrier configuration information of the base station is transmitted to the terminal by combining the third transmission method and the fourth transmission method.
Fig. 6 is a flowchart illustrating a base station sending multi-carrier configuration information of the base station to a terminal in this embodiment, and as shown in fig. 6, the sending of the multi-carrier configuration information of the base station to the terminal by the base station mainly includes the following steps:
step 601, the base station sends a multi-carrier configuration message carrying multi-carrier configuration information of the base station according to a preset or informed period broadcast, and the terminal receives the multi-carrier configuration message and acquires the multi-carrier configuration information of the base station from the multi-carrier configuration message.
Step 603, the terminal needs the multi-carrier configuration information in the subsequent process, if the multi-carrier configuration information of the base station is not obtained in step 601, the terminal sends a request message of the multi-carrier configuration information to the base station to request a unicast multi-carrier configuration message to the base station, and after receiving the multi-carrier configuration message, the base station executes the process as described in embodiment two, which is not described again in detail.
If the terminal receives the secondary carrier allocation message of the base station before it has not received the multi-carrier configuration information, in step 603, the terminal may carry an indication that the multi-carrier configuration information is not received in the secondary carrier allocation response message, and the base station sends a unicast multi-carrier configuration message to the terminal when receiving the indication. Or, the terminal directly sends a request message for configuring the information by multiple carriers to the base station, and requests the base station to send the multiple carrier configuration message.
According to the embodiment of the invention, the invention also provides a secondary carrier allocation method, which is used for allocating the secondary carrier for the terminal by the base station in the multi-carrier wireless communication system.
Fig. 7 is a flowchart of a secondary carrier allocation method according to an embodiment of the present invention, and as shown in fig. 7, in a multi-carrier network access procedure of a terminal, or after the terminal completes network initial access following a network access procedure of a single carrier wireless communication system, the following steps are performed (steps 701-705):
step 701: a terminal acquires multi-carrier configuration information broadcasted by a base station;
step 703: the terminal and the base station interact basic multi-carrier capability;
step 705: the terminal and the base station interact specific multi-carrier capability, and the base station distributes auxiliary carriers for the terminal.
In the specific implementation process, the process of network access of the terminal mainly includes the following steps:
step 3, initially ranging and adjusting parameters;
step 4, pre-authorization capability negotiation process;
step 5, authentication and key exchange;
step 6, capability negotiation and registration;
and 7, completing the initial access of the network.
In a specific implementation process, the secondary carrier allocation method provided in the embodiment of the present invention includes four implementation manners, and each implementation manner is described below.
Implementation mode one
In the embodiment, the terminal and the base station interact basic multi-carrier capability in the pre-authorization capability negotiation process, interact specific multi-carrier capability in the negotiation and registration process, and allocate auxiliary carriers to the terminal.
In this embodiment, the network access procedure of the terminal mainly includes the following steps:
step 3, initially ranging and adjusting parameters;
step 4, pre-authorizing a capability negotiation process, wherein the terminal carries basic multi-carrier capability information of the terminal in a basic capability negotiation request message (SBC-REQ), for example, whether the terminal supports multi-carrier capability, whether a carrier aggregation mode (carrier aggregation mode) is supported, whether a carrier switching mode (carrier switching mode) is supported, and the like; moreover, the basic capability negotiation request message may also carry an indication bit to indicate whether the terminal receives the multi-carrier configuration information; after receiving the SBC-REQ sent by the terminal, the base station carries its own basic multi-carrier capability information, e.g., whether it supports multi-carrier operation, in a basic capability negotiation response message (SBC-RSP).
If the base station supports multi-carrier operation and the received indication bit of the SBC-REQ indicates that the terminal does not receive the multi-carrier configuration information of the base station, the base station may carry the multi-carrier configuration information of the base station in the SBC-RSP, or the base station sends a unicast multi-carrier configuration message to the terminal.
Step 5, authentication and key exchange are carried out;
and 6, capability negotiation and registration.
In the process of step 4, if one of the terminal or the base station does not support the multi-carrier capability, the registration request (REG-REQ) message sent by the terminal is in the message format in the single-carrier mode. On the contrary, if both the terminal and the base station support the multi-carrier capability, there may be two processing manners: (1) the terminal carries the specific multi-carrier capability information of the terminal or a carrier list supported in a current available carrier set of the terminal in a transmitted REG-REQ message, and the base station carries the specific multi-carrier capability information of the base station in a registration response (REG-RSP) message returned to the terminal and allocates an auxiliary carrier for the terminal; (2) the terminal carries the specific multi-carrier capability information of the terminal or a carrier list supported in the current available carrier set of the terminal through a multi-carrier request message (MC-REQ), and the base station carries the specific multi-carrier capability information of the base station through a multi-carrier response message (MC-RSP) and allocates auxiliary carriers for the terminal.
