Wireless communication method and device

The present application claims priority to Chinese Patent Application No. 200710006462.4, entitled "Wireless Communication System Communication Method and Apparatus", filed on January 30, 2007, the entire contents of .

Technical field

The present invention relates to the field of wireless communications, and in particular, to a wireless communication method and device.

Background technique

Currently, the physical channels defined in the 3rd Generation Partnership Project 2 ("3GPP2") standard include: Forward Primary Broadcast Channel (F-PBCCH), Forward Forward Secondary Broadcast Channel (F-SBCCH), Forward Shared Control Channel (F-SCCH), Forward Power Control Channel (referred to as "Forward Power Control Channel") F-PCCH"), Forward Acknowledgement Channel ("F-ACKCH").

Among these channels, the F-SCCH belongs to the forward control channel and is mainly used for transmitting resource management messages. The forward control channel (hereinafter referred to as the control channel) is a very important channel, and includes other channels in addition to the F-SCCH, and is mainly used for transmitting access permission, resource assignment, ACK response, power control, and the like.

The number of resources and location information occupied by the control channel are transmitted in the F-SBCCH. Generally, the number of resources occupied by the control channel and the location information are transmitted once every 2 superframes (48 frames) in the F-SBCCH, during which the resources allocated to the control channel remain unchanged. Since the number of resources occupied by other subchannels in the control channel is substantially unchanged, the number of resources occupied by the control channel is related to the maximum number of information that the F-SCCH is expected to carry during this period.

The F-SCCH channel is used to transmit messages such as access grants, resource assignments, and the like. The F-SCCH channel is connected by multiple Messages. Each Message uses the same code modulation mode and is scrambled by using the MAC Address (Medium Access Control Identity) of the target access terminal ("AT"). After the entire control channel symbol is interleaved, transmission. The F-SCCH channel contains a variety of Messages, which differ in length by a small amount. To simplify the system, all Messages are expanded to a uniform length by zero-padding and concatenated into a Message sequence. If the number of Messages sent is less than the system reference value, zero is added after the Message sequence to achieve the required length. Degree.

The F-SCCH channel includes signaling that may occur in each physical frame (time slot) such as forward resource assignment signaling, reverse access acknowledgement signaling, and broadcast/multicast signaling. As shown in Table 1, there are different signaling types in the Field column, such as "Access Grant", "RLAM" (Reverse Link Assignment Message), and "FLAM" (Forward). Link Assignment Message, forward link assignment message, etc. The Access Grant is used to confirm the reverse access of the terminal; the FLAM is used for forward channel assignment; and the RLAM is used for the assignment of the reverse channel resource.

MCW-FLAM1 (Multi-Code Word - Forward Link Assignment Message) is used to make Multiple Input Word (Multiple Code Multiple, Multiple Input Multiple Output ("ΜΙΜΟ"). The resource assignment in the "MCW" mode is referred to as the packet format (Packet Format, referred to as "PF") in the first layer of MIMO.

The MCW-FLAM2 contains PF information of the other three layers.

In the existing reverse access process, after receiving the reverse access probe sent by the terminal, the base station sends an Access Grant to the terminal, and simultaneously or subsequently sends the RLAM to the terminal, which is used to assign the terminal to send.

The reverse channel resource required by BindUATI (Binding Access Terminal Identity). However, the inventors of the present invention found that sending Access Grant and RLAM would Greatly reduce the efficiency of signaling and increase the system load.

At the same time, the inventors of the present invention have also found the following problems.

Since all signaling needs to be padded to a uniform length, for those message types that are not the maximum length, the zero padding area creates a waste of resources.

In the prior art MCW mode assignment signaling, the PF has a total of 4 layers. When using more than 1 layer packet format, MCW-FLAM1 is used to transmit the first layer of PF, and MCW-FLAM2 is used to transmit the other 3 layers. PF. When the other PFs of the 3 layers are the same as the PFs of the first layer, it is unnecessary to send the MCW-FLAM2, which only reduces the efficiency of signaling and increases the system load.

When the FLAM is sent, in some cases, the system needs to receive the FLAM after receiving the FLAM. In some cases, it does not need to be used. In addition, the time required to feed back the ACK may be different. In the current system, it can only be configured through the system broadcast channel, and the flexibility is not enough.

detailed description

The invention will be further described in detail below with reference to the accompanying drawings.

A first embodiment of the present invention relates to a method for transmitting and receiving wireless communication signaling. In this embodiment, Adding a channel identification field Channel ID (for 6M systems, 6 bits) in the access grant signaling Access Grant sent by the system to the terminal, where the value indicates the reverse channel node number assigned by the base station to the terminal, as shown in Table 2. Show. The reverse channel node number may be a valid channel node number and an invalid channel node number. The invalid channel node number is derived from channel resources corresponding to some nodes in the channel tree that cannot be assigned through Access Grant signaling, such as a channel node corresponding to the carrier protection band and a channel node corresponding to the control channel.

Table 2

Specifically as shown in Figure 1. In step 110, the base station captures the reverse access probe of the terminal.

Next, proceeding to step 120, before the F-SCCH sends the access grant signaling Access Grant to the terminal, the base station determines whether the terminal has been allocated a reverse channel resource, and the reverse channel resource is used for the terminal to send the BindUATI information. If it has been allocated, proceed to step 130, send an access grant signaling Access Grant to the terminal in the F-SCCH, and include a channel identification field in the transmitted Access Grant, where the value in the channel identification domain is assigned to the terminal by the base station. The effective channel node number of the reverse channel. By adding a channel identification field in the Access Grant, both the access permission and the reverse channel resource allocated to the terminal can be completed in one signaling, thereby saving a RLAM signaling specifically indicating the reverse channel resource allocated for the terminal. The signaling efficiency of the F-SCCH channel is enhanced. If the reverse channel resource has not been allocated, then step 140 is entered.

In step 140, the access grant signaling Access Grant is sent to the terminal in the F-SCCH, and the channel identification domain Channel ID is included in the transmitted Access Grant, and the value in the channel identifier field is an invalid channel node number. Then proceed to step 150. In step 150, the base station sends a reverse link assignment message RLAM signaling to the terminal when there is a reverse traffic channel assignment in the subsequent frame, to assign the reverse channel resource. Therefore, it is possible to adapt to the case where the reverse channel resource is not allocated to the terminal when the Access Grant is sent.

After receiving the Access Grant, the terminal obtains the reverse channel resource allocated by the network side for the terminal according to the value of the channel identifier field in the Access Grant: if the value of the channel identifier field is a valid channel node number, the effective channel node number is used. The corresponding channel node is used as a reverse channel resource allocated by the system for the terminal; if the value of the channel identification field is an invalid channel node number, the RLAM signaling for assigning the reverse channel resource is further detected, and the same can be obtained. The channel number of the BindUATI message.

The second embodiment of the present invention also relates to a method for transmitting and receiving signaling of a wireless communication system. Similar to the first embodiment, the present embodiment further utilizes the invalid channel number based on the first embodiment.

Specifically, in the present embodiment, the correspondence relationship between the invalid channel node number and the carrier is stored in advance on the network side and the terminal. When the Access Grant is sent, if the reverse channel resource has not been allocated to the terminal, the invalid channel node number corresponding to the carrier is selected as the value in the channel identification field, indicating that the terminal waits for the RLAM channel resource assignment on the carrier. Indicating carrier information by an invalid channel number further improves the utilization efficiency of signaling. After receiving the Access Grant, if the value of the channel identification field is the effective channel node number, the terminal processes the same manner as the first embodiment; if the value of the channel identification field is an invalid channel node number, the invalid channel is used. The RLAM signaling for assigning the reverse channel resource is detected on the carrier corresponding to the node number.

For example, in the band resource used for transmission, the channel node number of the guard band is the invalid channel node number. Let the guard node's channel node numbers be 0 and 31, then their parent nodes 32 and 48 are also invalid channel node numbers. The correspondence between the invalid channel node number and the carrier number is established: node number 0 represents carrier 0, node number 31 represents node number 1, node number 32 represents carrier 2, and node number 48 represents carrier 3. If the base station receives the access probe sent by the terminal on the reverse access channel of carrier 0, and does not allocate the reverse channel resource when sending the access grant to the terminal, set the invalid channel node number in the channel identifier field of the Access Grant. The terminal is notified by the invalid channel node number to wait for receiving the RLAM channel resource assignment on the corresponding carrier. If the load on the current carrier 0 is large, the base station may set the invalid channel node number 48 corresponding to the carrier 3 with a relatively small load in the channel identification field. After receiving the access Grant, the terminal waits for the RLAM to be received on the carrier 3, so that the load of each carrier is balanced. By coordinating the load between different carriers, the utilization of resources is indirectly improved.

The third embodiment of the present invention also relates to a method for signaling and receiving a wireless communication system. In this embodiment, the base station includes the time extension information (which may be multiple bits) in the Access Grant, and is used to indicate that the current system of the terminal is in a busy state, and requires the terminal to try to access or detect the resource finger after a delay. With signaling RLAM. The time extension can be in units of frames or in superframes. After receiving the access grant, the terminal attempts to access or detect RLAM signaling after a specified length of delay according to the indication of the time extension information. This method can reduce the inefficient detection of the terminal when the system is busy, so as to save terminal energy consumption. Moreover, the method increases the amount of information transmitted without increasing the number of signaling, and enhances the signaling efficiency of the F-SCCH channel.

The fourth embodiment of the present invention also relates to a method of signaling transmission and reception of a wireless communication system, similar to the third embodiment. In this embodiment, the detection period information (which may be multiple bits) is added to the Access Grant to indicate that the current system of the terminal is busy, and the terminal is required to detect the RLAM in a lower period, for example, by using multiple frames as the interval. One detection cycle. After receiving the Access Grant, the terminal performs RL AM signaling detection by using the period length indicated by the detection period information. This method can also reduce the invalid detection of the terminal when the system is busy, so as to save terminal energy consumption. Moreover, the method increases the amount of information transmitted without increasing the number of signaling, and enhances the signaling efficiency of the F-SCCH channel.

The fifth embodiment of the present invention also relates to a method for signaling transmission and reception of a wireless communication system, similar to the third embodiment. In this embodiment, the busy indication information (only 1 bit) is added to the Access Grant to indicate that the current system is in a busy state, and the terminal is required to delay the access for a period of time to try to reduce the system load. According to the busy indication information in the Access Grant, the terminal tries to access after a delay, thereby reducing the possibility of terminal access failure, and reducing the system burden while saving the terminal's energy consumption. Moreover, the method increases the amount of information transmitted without increasing the number of signaling, and enhances the signaling efficiency of the F-SCCH channel.

The above embodiments may be combined to form a new embodiment in any combination, as long as the message length after increasing the corresponding domain is equal to or smaller than the maximum length.

A sixth embodiment of the present invention relates to a wireless communication method. In this embodiment, the FLAM signaling sent by the network side terminal includes an acknowledgment field (which may be one or more bits), and is used to indicate whether the terminal needs feedback ACK or acknowledgment after receiving the FLAM signaling. The message NACK, and the first few packets in the subsequent packet, feed back ACK/NACK. If the value of the confirmation field is 0, it means no need To feedback, the value of the acknowledgment field is N, indicating that the Nth sub-package feedback confirmation or non-confirmation information after receiving the FLAM assignment, where N is not zero. After receiving the FLAM signaling, the terminal does not feed back the ACK/NACK information if the value in the acknowledgment field is 0. If it is not 0, the ACK/NACK information is fed back to the sub-packet indicated by the value of the acknowledgment field. This embodiment increases the signaling function without increasing the number of signaling, and enhances the signaling efficiency of the F-SCCH channel.

The FLAM signaling in this embodiment may be: a Transmit Diversity Forward Link Assignment Message ("TD-FLAM"), or a sub-band transmit diversity forward assignment message (Sub-Band) Transmit Diversity FLAM (abbreviated as "SB-TD-FLAM"), or Residual Resource Assignment Transmit Diversity FLAM ("RAA-TD-FLAM").

The seventh embodiment of the present invention also relates to a wireless communication method. In this embodiment, the multi-codeword forward link assignment message sent by the network side terminal includes a first layer packet format and a field indicating a relationship between the first layer and other layer packet formats. The values of the fields indicating the packet format of the first layer and other layer packet formats include: a value indicating that the first layer is identical to other layer packet formats, and/or a value indicating a difference between the first layer and other layer packet formats. For example, if the first layer packet format is type 3 and the second layer to fourth layer packet format is type 5, the value in the field is the difference 2 between the two. After receiving the MCW-FLAM signaling, the terminal can obtain the packet format of other layers according to the value of the first layer packet format and the domain of the first layer and other layer packet formats. By adding a domain indicating the relationship between the first layer and other layer packet formats in various MCW-FLAM signaling, the multi-layer packet format information can be transmitted in one message, which saves the specific layer packet format dedicated to the delivery of the first layer. Signaling of information enhances the signaling efficiency of the F-SCCH channel.

The MCW-FLAM signaling in this embodiment includes: MCW-FLAM1, synchronous burst multi-codeword forward link assignment message SB-MCW-FLAM1, and radio resource access multi-codeword forward link finger With the message RRA-MCW-FLAM1.

The eighth embodiment of the present invention relates to a base station. As shown in FIG. 2, the method includes: a capturing unit 21, configured to capture a reverse access probe of the terminal; and a setting unit 22, configured to be used in the access grant signaling Access Grant. Setting a channel identification field Channel ID, the value in the channel identification field indicates a reverse channel node number assigned by the base station to the terminal; and the Access Grant sending unit 23 is configured to send an Access Grant to the terminal in the F-SCCH. After the capture unit 21 captures the reverse access probe of the terminal, the setting unit 22 sets a channel identification field in the Access Grant, and then sends the signaling through the Access Grant sending unit 23. Pass Adding a channel identification field in the Access Grant can complete both the access permission and the reverse channel resource allocated to the terminal in one signaling, thereby saving a RLAM signaling specifically indicating the reverse channel resource allocated for the terminal, and enhancing The signaling efficiency of the F-SCCH channel.

The reverse channel node number allocated by the base station to the terminal includes a valid channel node number and an invalid channel node number, and the setting unit 22 sets the channel identification field by: when transmitting the Access Grant, if the terminal has been assigned a reverse channel Resource, the value in the channel identification field is set to the effective channel node number of the assigned reverse channel; when the Access Grant is sent, if the terminal has not been assigned a reverse channel resource, the value setting in the channel identification field Is the invalid channel node number. The base station further includes a unit for transmitting RLAM signaling (not shown). If the value of the channel identifier field in the Access Grant is an invalid channel node number, the reverse channel resource is allocated by sending RLAM signaling, so that the base channel can be adapted to be sent. The Access Grant has not been assigned a reverse channel resource for the terminal.

The base station may further include a saving unit 24 that saves the correspondence between the invalid channel node number and the carrier; the setting unit 22 selects the invalid signal node number corresponding to the carrier as the value in the channel identification field, and instructs the terminal to wait for the RLAM on the carrier. Channel resource assignment, so that the RLAM can be transmitted through a carrier with a lower load, so that the load of each carrier tends to be balanced, and the resource utilization is indirectly improved by coordinating the load between different carriers.

The base station may further include: a unit for transmitting a forward link assignment message FLAM signaling to the terminal (not shown); and a unit for confirming the domain (not shown) in the FLAM signaling, the confirmation field is used for The sub-packet feedback confirmation or non-confirmation information indicating the value indicated by the terminal in the confirmation field. In this way, the signaling function is added without increasing the number of signaling, and the signaling efficiency of the F-SCCH channel is enhanced. The value of the acknowledgment field is zero, indicating that no feedback is needed. When the value of the acknowledgment field is N, it indicates that the Nth sub-packet feedback acknowledgment or non-confirmation information after receiving the FLAM assignment, where N is not zero. The FLAM signaling here includes: TD-FLAM, SB-TD-FLAM, and RRA-TD-FLAM.

The base station may further include: a unit for transmitting MCW-FLAM signaling to the terminal (not shown); setting a first layer packet format in the MCW-FLAM signaling, and indicating a relationship between the first layer and other layer packet formats. The unit of the domain (not shown). After the terminal receives the MCW-FLAM signaling, the packet format of the other layer may be obtained according to the value of the first layer packet format and the domain of the first layer and other layer packet formats. The multi-layer packet format information can be transmitted in one message, which saves the signaling for transmitting the layer layer format information other than the first layer, and enhances the signaling efficiency of the F-SCCH channel. The value of the field indicating the packet format of the first layer and the other layer packet format includes: a value indicating that the first layer is identical to other layer packet formats, and/or a value indicating a difference between the first layer and other layer packet formats.

The MCW-FLAM signaling mentioned here includes: MCW-FLAM1, SB-MCW-FLAM1, and RRA-MCW-FLAM1.

The base station may further include: a unit (not shown) that sets information indicating the degree of extension in the Access Grant sent to the terminal; or a unit that sets information indicating the detection period in the Access Grant (not shown) ; or a unit that sets the busy indication information in Access Grant (not shown). When the terminal receives the Access Grant, it may try to access or detect the RLAM signaling according to the delay of the specified extension; or, the RLAM signaling is detected by using the specified detection period; or, according to the busy Indicate the information, and try to access it after a delay. Therefore, when the system is in a relatively busy state, the terminal is instructed to perform an access attempt or RLAM signaling detection with an appropriate time extension or detection period, and the amount of information transmitted is increased without increasing the number of signaling, and the F is enhanced. - Signaling efficiency of the SCCH channel.

Since a channel identification field is added in the Access Grant, the terminal can obtain an access permission from one signaling and a reverse channel resource allocated by the network side to the terminal, thereby saving a reverse channel resource specifically allocated for the terminal. The RLAM signaling improves the signaling efficiency of the F-SCCH channel, reduces the number of times the terminal detects the received signaling, and saves the energy consumption of the terminal.

The obtaining unit 32 includes: a determining module 321 , configured to determine whether the value of the channel identifier field is a valid channel node number, and if the determining module determines that the value of the channel identifier field is a valid channel node number, the effective channel node number is used. The corresponding channel node is used as the reverse channel resource allocated by the system for the terminal; the detecting module 322 is configured to detect, when the determining module determines that the value of the channel identifier field is an invalid channel node number, RLAM signaling for channel resources. Therefore, it is possible to adapt to the case where the reverse channel resource is not allocated to the terminal when the Access Grant is sent.

The terminal may further include: a saving module 33 that saves a correspondence between the invalid channel node number and the carrier; and the detecting module 322 detects the RLAM signaling on the carrier corresponding to the invalid channel node number, Therefore, the network side can transmit RLAM signaling through a carrier with a small load, so that the load of each carrier tends to be balanced, and the resource utilization is indirectly improved by coordinating the load between different carriers.

The terminal may further include: a module that attempts to access or detect RLAM signaling after the length delay is included in the Access Grant (not shown); or includes detection in the Access Grant a module for detecting RLAM signaling by using the detection period (not shown); or, when the busy indication information is included in the Access Grant, the module that tries to access after delaying for a period of time (not shown in the figure) ). Therefore, the possibility of terminal access failure is reduced, and the power consumption of the terminal is saved while reducing the burden on the system.

The terminal may further include: a module for receiving FLAM signaling from the network side (not shown), and a module for confirming the acknowledgement or non-confirmation information of the sub-packet indicated by the value of the acknowledgement field according to the acknowledgement field in the FLAM signaling (not shown). If the value of the acknowledgment field is zero, no feedback is provided. If the value of the acknowledgment field is N, the Nth sub-packet after receiving the FLAM assignment feedback acknowledgment or non-confirmation information, where N is not zero. Therefore, without increasing the number of signaling, the terminal can also specify whether feedback is needed and how to feed back acknowledgment or non-acknowledgement information, which enhances the signaling efficiency of the F-SCCH channel. The FLAM signaling here includes: TD-FLAM, SB-TD-FLAM, and RRA-TD-FLAM.

The terminal may further include: a module for receiving MCW-FLAM signaling sent by the network side (not shown); according to the first layer packet format in the MCW-FLAM signaling, and the relationship between the first layer and other layer packet formats The value of the field, the module that obtains the packet format of other layers (not shown). The value of the field indicating the packet format of the first layer and the other layer packet format includes: a value indicating that the first layer is identical to other layer packet formats, and/or a value indicating a difference between the first layer and other layer packet formats. By adding a field indicating the relationship between the first layer and other layer packet formats in various MCW-FLAM signaling, only one message is required to enable the terminal to obtain multi-layer packet format information, saving the use of the first layer other than the first layer. Layer packet format information signaling enhances the signaling efficiency of the F-SCCH channel. The MCW-FLAM signaling here includes: MCW-FLAM1, SB-MCW-FLAM1, RRA-MCW-FLAM1.

In summary, in various embodiments of the present invention, by adding a channel identification field in the access permission signaling, both the access permission and the reverse channel resource allocated to the terminal can be completed in one signaling, thereby Saving a RLAM signaling specifically indicating the reverse channel resources allocated for the terminal enhances the signaling efficiency of the F-SCCH channel.

Invalid channel numbers can also be used to indicate information such as carriers, thereby further improving the efficiency of signaling utilization.

The access grant signaling may further increase information such as time extension, detection period, or busy indication, so that the terminal performs access attempt or RLAM signaling with an appropriate time extension or detection period when the system is in a busy state. The detection increases the amount of information transmitted without increasing the number of signaling, and enhances the signaling efficiency of the F-SCCH channel.
