Description

Method, system, base station and terminal for processing message for informing terminal to process message

The present invention relates to the field of information transmission, and in particular to a method, system, base station and terminal for processing a message for notifying a terminal to process a message. Background technique

The forward control channel is a very important channel in the communication process, and each frame carries information transmission, and is mainly used for transmitting access permission, resource assignment, response (ACK), power control and the like. For convenience of description, the forward control channel is simply referred to as a control channel. The control channel includes a Forward Shared Signaling Channel (F-SCCH) for transmitting resource management messages and other channels.

The number and location of resources occupied by the control channel are transmitted in a Secondary Broadcast Channel (F-SBCCH), which is a channel corresponding to the primary broadcast channel. Generally, every two superframes, that is, 48 frames, transmit the number and location of resources occupied by the control channel on the F-SBCCH. The amount of resources allocated to the control channel remains unchanged during the two superframes. The amount of resources occupied is related to the maximum number of information that the F-SCCH is expected to carry. The amount of resources occupied by other subchannels in the control channel remains basically the same.

The F-SCCH is used to transmit messages such as access grants, resource assignments, etc., and contains various control messages, as shown in Table 1, which are of different lengths. When a control message needs to be sent, each control message is padded to a uniform length, and then the same coded modulation mode is used, and a Media Access Control (MAC) identifier (MACID) for broadcast or multicast is used. Or the MAC address of the target terminal (Access Termination, AT) is scrambled and sent. The control message after the above processing is called a control message block. All control message blocks are concatenated to form a sequence of control messages that are interleaved and mapped onto the physical channel. If the number of control message blocks that need to be sent is less than the system preset value, add all zero control after the control message sequence before mapping to the physical channel. The message block is made to reach the required length. An all zero control message block does not contain any control information and thus may be referred to as an idle message block, whereas a message block containing a control message is referred to as a valid control message block. An idle message block can be included in the control message sequence. Since the idle message block does not contain any control information, the transmission of the idle message block causes waste of resources. This waste is especially noticeable when the number of idle message blocks is relatively large.

Table 1 Schematic diagram of F-SCCH control message structure

In order to utilize the wasted resources, the existing protocol proposes a method for the data channel to share the control channel resources on the basis of the original, that is, the resources occupied by the idle message blocks in each frame of the control channel, that is, the idle resources are reallocated to the data channel for use. '

In order to reduce the overhead, the amount of resources occupied remains unchanged each time the hybrid automatic repeat request (HQQ) is retransmitted; however, because the information transmitted by the control channel is different, the number of unused resources of the control channel It is uncertain. Thus, the resources shared by the control channel for use by the data channel are preferably used for the transmission of redundant information. Redundant information means that the AT is positive Often, the information that does not affect the service data is processed. The redundant information is only used to improve the performance of the service data. That is, when the AT processes the service data, even if the redundant information is lacking, the service data can be correctly acquired.

In order to achieve the purpose of sharing control channel resources for the data channel, the access network (AN) needs to notify the AT control channel (mainly F-SCCH) of the use of resources, and further implement the assignment of idle resources. Currently, the AN notifies the AT control message block of the use of resources by sending a Packet Data Control Assignment Message (PDCAM) to the AT.

The PDCAM indicates the use of resources by the control message block by means of a bit map. That is, when the number of control message blocks included in the control message sequence is N, the PDCAM needs to carry N bits, and each bit is used for identification. Control whether the message block is used accordingly. However, since the PDCAM uses the bit indication to identify the use of resources by the control channel, when the number of control message blocks that should be included in the control message sequence is large, multiple PDCAMs are required to completely notify the AT whether the control message blocks are used. For example, the control message block is transmitted in a high-order modulation mode. The resource that originally stored a control message block can carry multiple control message blocks, so that the total number of control message blocks will be very large. At this time, the corresponding control message block indicated in each PDCAM can be determined by the sub-map index number (sub seven itmap index) shown in Table 1. Each PDCAM that is transmitted needs to occupy resources. When multiple PDCAMs need to be transmitted to completely notify the AT that each control message block is used, it will inevitably lead to excessive use of resources and waste of resources.

In addition, since each control message block may be scrambled by the broadcast MACID or the MAC ID of the target AT (the former is called a broadcast message, the latter is called a unicast message, and the effective control message includes these two types of messages), so that the AT receives After the control message sequence, it may be necessary to descramble the control message block twice to determine whether the control message block is related to the AT, which inevitably increases the load on the AT and prolongs the time required for the AT to process the control message block. Reduce the processing performance of the AT.

In addition, if the idle resource needs to be assigned to the AT to transmit the redundant information of the AT, each assignment needs to send a complete assignment message to the AT, such as a forward link assignment message (FL Assignment). Message, FLAM), the control message block used to allocate idle message blocks to occupy resources requires additional resources, resulting in waste of resources.

In summary, the role of existing control message blocks and their transmissions make processing performance very low. Summary of the invention

detailed description

In the solution provided by the embodiments of the present invention, the AN transmits a message block having a specific attribute at a set position of the control message sequence, and notifies the AT of the number of message blocks having a specific attribute currently transmitted. The AT may carry the number of message blocks of a particular attribute currently being transmitted in a PDCAM or other control message. The message block with a specific attribute can be provided to the AT by the AN at the set position of the control message sequence. In the subsequent processing, the AT sets the position of the control message sequence according to the message block with the specific attribute and the specific attribute received. The number of message blocks processes the message block. The set position of the control message sequence may be the front of the control message sequence, or the back of the control message sequence, or a specific location of the control message sequence, or a starting position in a control message sequence. A message block of a specific attribute refers to a message block having certain common characteristics, such as a valid control message block, an idle message block not containing control information, a valid control message block scrambled using a broadcast MACID, and a scrambling using the MAC ID of the target AT. A valid control message block for the code. The effective control message block described in the embodiment of the present invention may be a control message block containing control information, and may also be a combination of a control message block containing control information and an idle message block not allocated to the AT for data transmission.

Hereinafter, for convenience of description, an effective control message block for scrambling using a broadcast MACID is referred to as a broadcast control message block, and an effective control message block for scrambling using a MAC address of a target AT is referred to as a unicast control message block. Since multicast and broadcast are implemented in substantially the same manner, the embodiments provided by the present invention do not distinguish between multicast and broadcast, and are collectively referred to as broadcast.

The scheme provided by the embodiments of the present invention is described in detail below by taking the number of the message blocks of the specific attributes that are currently transmitted in the PDCAM as an example. In addition to the number of message blocks carrying the specific attributes currently transmitted, the PDCAM may further carry other related information, and the following embodiments describe the role of the related information further carried in the PDCAM.

FIG. 1 is a schematic diagram showing the structure of a PDCAM in the first embodiment of the present invention. As shown in FIG. 1, in this embodiment, an AN transmits a valid control message block at a set position of a control message sequence, and the AN notifies the AT that the current transmission is valid. Controlling the set position of the control message sequence of the message block, the PDCAM sent by the AN to the AT carries the block type and the number of effective control message blocks. The block type is used to identify the control message as PDCAM. The PDCAM may further include reserved information, where the reserved information may be the number of broadcast control message blocks or the number of unicast control message blocks; or, the AT identity information, used to implement the assignment of idle message block occupation resources; or, Whether to identify whether the auxiliary information is persistently allocated information; or, corresponding Packet Format (PF) information; or, modulation information of each control message block; or, the length of each control message block; or , any combination of the above.

After receiving the PDCAM, the AT processes the control message block according to the number of effective control message blocks at the set position of the control message sequence, that is, processes the control message block at the set position of the control message sequence, and controls the corresponding control. The number of message blocks is the number of valid control message blocks.

FIG. 2 is a schematic diagram showing the structure of the PDCAM in the second embodiment of the present invention. As shown in FIG. 2, in the embodiment, the AN transmits an effective control message block at a set position of the control message sequence, and the AN further forms a valid control message block. The broadcast control message block is transmitted at the set position of the sequence, and the message block is effectively controlled. The set position of the composed sequence is actually also a certain set position of the control message sequence, and the AN notifies the AT that the currently transmitted effective control message block is in the set position of the control message sequence, and the transmitted broadcast control message block is valid. Controls the set position of the sequence of message blocks. The PDCAM sent by the AN to the AT carries the block type, the number of effective control message blocks, and the number of broadcast control message blocks.

After receiving the PDCAM, the AT processes the control message block according to the number of effective control message blocks at the set position of the control message sequence, and according to the set position of the sequence of the effective control message block, according to the number of broadcast control message blocks The broadcast control message block is processed, that is, the control message block is processed at the set position of the control message sequence, the number of corresponding control message blocks processed is the number of effective control message blocks, and the sequence of the effective control message block is The broadcast control message block is processed at the set position, and the broadcast control message block is descrambled using the broadcast MACID. The number of corresponding broadcast control message blocks processed is the number of broadcast control message blocks, and the remaining control message blocks can be regarded as unicast. The control message block uses the own MACID to descramble the unicast control message block, and the number of corresponding unicast control message blocks processed is the difference between the number of effective control message blocks and the number of broadcast control message blocks.

3 is a schematic structural diagram of a PDCAM in Embodiment 3 of the present invention. As shown in FIG. 3, in this embodiment, an AN transmits a valid control message block at a set position of a control message sequence, and the AN notifies the AT of the current transmission. The effective control message block is in the set position of the control message sequence, and the PDCAM sent by the AN to the AT carries the block type, the number of effective control message blocks, and the AT identity information. The AT identity information is used to assign an idle resource to the corresponding AT, and the AT identity information may be one or more. The AT identity information may be MACID > or channel identifier (ChanID), or resource block number, or mini MACID, or other associated with the AT.

After receiving the PDCAM, the AT processes the control message block according to the number of effective control message blocks at the set position of the control message sequence, that is, processes the control message block at the set position of the control message sequence, and controls the corresponding control. The number of message blocks is the number of effective control message blocks; and, the AT also needs to determine whether the AT identity information contains its own AT identity information, and if so, continues to set the location and effective control of the control message sequence according to the effective control message block. The number of message blocks determines the location of the idle resource, then determines the idle resource assigned to itself, and uses the resource; otherwise, ends the current flow Cheng.

When the number of AT identity information carried in the PDCAM is multiple, when the idle resource is assigned to multiple ATs, the allocation of idle resources, such as average allocation, may be performed by using an allocation manner pre-negotiated by the AN and the AT. For example, if the number of idle message blocks is 4, and the corresponding idle resources are assigned to two ATs, the AT corresponding to the first AT identity information obtains the idle resources corresponding to the first two idle message blocks, corresponding to the second AT identity. The AT of the information obtains the idle resources corresponding to the two idle message blocks. When AN allocates idle resources, it also allocates idle resources according to the pre-negotiated distribution method.

FIG. 4 is a schematic diagram showing the structure of a PDCAM in the fourth embodiment of the present invention. As shown in FIG. 4, in the embodiment, the AN transmits an effective control message block at a set position of the control message sequence, and the AN further forms an effective control message block. The broadcast control message block is transmitted at the set position of the sequence, and the AN notifies the AT that the currently transmitted effective control message block is in the set position of the control message sequence, and the transmitted broadcast control message block is in the sequence of the effective control message block. Set the location. The PDCAM sent by the AN to the AT carries the block type, the number of effective control message blocks, the number of broadcast control message blocks, and the AT identity information.

After receiving the PDCAM, the AT processes the control message block according to the number of effective control message blocks at the set position of the control message sequence, and according to the broadcast control message at the set position of the sequence of the effective control message block. The number of blocks processes the broadcast control message block, that is, the control message block is processed at the set position of the control message sequence, the number of corresponding control message blocks processed is the number of effective control message blocks, and the effective control message block is composed. The broadcast control message block is processed at the set position of the sequence, and the broadcast control message block is descrambled using the broadcast MACID. The number of corresponding broadcast control message blocks processed is the number of broadcast control message blocks, and the remaining control message blocks can be regarded as The unicast control message block uses the own MACID to descramble the unicast control message block, and the number of corresponding unicast control message blocks processed is the difference between the number of effective control message blocks and the number of broadcast control message blocks; Does the AT identity information contain its own AT identity information, and if so, continue 4 The effective control message block determines the location of the idle resource in the set position of the control message sequence and the number of effective control message blocks, and then determines the idle resource assigned to itself, and uses the resource; otherwise, the current process is ended.

The number of broadcast control message blocks carried in the PDCAM described in FIG. 2 to FIG. 4 On the basis of the and/or AT identity, there may still be further reservation information.

In addition, the number of effective control message blocks carried by the PDCAM may be replaced by the number of idle message blocks not including the control information, and the AN still transmits the effective control message block at the set position of the control message sequence, and the AT is in the control message sequence. The process of processing the control message block according to the number of effective control message blocks at a fixed position is: processing the control message block at a set position of the control message sequence, and the number of corresponding control message blocks processed is a message included in the control message sequence. The difference between the number of blocks and the number of control message blocks that do not contain control information. Alternatively, the AN transmits a control message block that does not include control information at a set position of the control message sequence, and the AT processes the control message block according to the number of effective control message blocks at the set position of the control message sequence: The control message block is processed in a position other than the set position in the control message sequence, and the number of corresponding control message blocks processed is the difference between the number of message blocks included in the control message sequence and the number of control message blocks not containing the control information. . The PDCAM can further carry related information, such as the number of broadcast control message blocks and/or the AT identity, and the specific processing is basically the same as the above description, and details are not described herein again.

FIG. 5 is a schematic diagram showing the structure of a PDCAM according to Embodiment 5 of the present invention. As shown in FIG. 5, in this embodiment, an AN transmits a broadcast control message block at a set position of a control message sequence, and the AN notifies the AT of the current transmission. The broadcast control message block carries the block type and the number of broadcast control message blocks in the PDCAM sent by the AN to the AT in the set position of the control message sequence. The PDCAM may further include reserved information, where the reserved information may be an effective control message block number or an idle message block number; or, the AT identity information, used to implement an idle message block occupation resource allocation; or, for identifying Whether the auxiliary information is continuously allocated information; or, corresponding PF information; or, modulation information of each control message block; or, the length of each control message block; or any combination of the above.

After receiving the PDCAM, the AT processes the broadcast control message block according to the number of broadcast control message blocks at the set position of the control message sequence, that is, processes the control message block at the set position of the control message sequence, and uses the broadcast MACID. For the broadcast control message block descrambling code, the number of corresponding control message blocks processed is the number of broadcast control message blocks; the remaining control message blocks can be regarded as unicast control message blocks, and the unicast control message block descrambling code can be used by using its own MACID . FIG. 6 is a schematic diagram showing the structure of a PDCAM according to Embodiment 6 of the present invention. As shown in FIG. 6, in this embodiment, an AN transmits a broadcast control message block at a set position of a control message sequence, and the AN further sets a control message sequence. The effective control message block is transmitted at a fixed position, and the AN notifies the AT that the broadcast control message block currently transmitted is at the set position of the control message sequence, and the transmitted effective control message block is at the set position of the control message sequence. The PDCAM sent by the AN to the AT carries the block type, the number of broadcast control message blocks, the number of effective control message blocks, and the AT identity information.

After receiving the PDCAM, the AT processes the broadcast control message block according to the number of broadcast control message blocks at the set position of the control message sequence, that is, processes the control message block at the set position of the control message sequence, and uses the broadcast MACID. For the broadcast control message block descrambling code, the number of corresponding control message blocks processed is the number of broadcast control message blocks; the remaining control message blocks can be regarded as unicast control message blocks, and the unicast control message block descrambling code can be used by using its own MACID And, the AT also needs to determine whether the AT identity information includes its own AT identity information, and if so, continues to determine the location of the idle resource according to the set position of the control message sequence and the number of effective control message blocks according to the effective control message block, and then Determine the idle resources assigned to itself and use the resources; otherwise, end the current process.

FIG. 7 is a schematic diagram showing the structure of the PDCAM in the seventh embodiment of the present invention. As shown in FIG. 7, in the embodiment, the AN uploads a broadcast control message block at a set position of the control message sequence, and the AN further controls the message sequence. Transmitting a unicast control message block at a set location, and the AN notifying the AT of the set location of the control message sequence currently transmitting the broadcast control message block, and transmitting the unicast control message block at another set location of the control message sequence . The PDCAM sent by the AN to the AT carries the block type, the number of broadcast control message blocks, the number of unicast control message blocks, and the AT identity information.

After receiving the PDCAM, the AT processes the broadcast control message block according to the number of broadcast control message blocks at the set position of the control message sequence, that is, processes the control message block at the set position of the control message sequence, and uses the broadcast MACID. For the broadcast control message block descrambling code, the number of corresponding control message blocks processed is the number of broadcast control message blocks, and at another set position of the control message sequence, the unicast control message block is performed according to the number of unicast control message blocks. Processing, using the own MACID to descramble the unicast control message block, and the number of corresponding control message blocks processed is the number of unicast control message blocks; and, AT W also needs to determine whether the AT identity information of the AT identity information is included, and if so, continue to set the location of the control message sequence and the number of broadcast control message blocks according to the broadcast control message block and the unicast control message block, and unicast The number of control message blocks determines the location of the idle resource, and then determines the idle resource assigned to itself, and uses the resource; otherwise, the current process ends.

When the number of broadcast control message blocks is only carried in the PDCAM, the number of the broadcast control message blocks can be replaced by the number of the unicast control message blocks. The specific processing is basically the same as the above description, and only the corresponding change of the descrambling code mode is omitted.

When the number of control message blocks with the number of effective control message blocks or the control information is not included in the PDCAM, the PDCAM function in Table 1 can be realized by simply indicating the number in the PDCAM. In the embodiment provided by the present invention, only about log ₂ ^w bits are needed to be expressed. Since the entire control channel needs to be interleaved to be mapped to the actual physical channel, the solution provided by the embodiments of the present invention does not have any negative impact, and the original diversity characteristics can still be satisfactorily satisfied.

When the number of broadcast control message blocks or the number of unicast control message blocks is carried in the PDCAM, the AT can directly determine the descrambling code mode of the corresponding control message block, and the descrambling code method adopted by the AT does not occur again, and again In the case of performing descrambling, the processing performance of the AT is improved, and the load of the AT is reduced as compared with the prior art.

When the PDCAM further carries the AT identity information, the assignment of the idle resources can be implemented through one PDCAM, and the idle resources need not be assigned through the separate assignment message, because one assignment message occupies the basic node resources (Base Node In this way, when the M assignment message is omitted, the resources occupied by about M/3 to M/2 basic resource nodes can be saved, and the transmission efficiency is improved.

When the PDCAM described above is transmitted, a separate control assignment channel dedicated to transmitting the PDCAM may be set, and then the PDCAM may be transmitted using the control assignment channel; or the PDCAML may be transmitted using an existing control channel (such as F-SCCH).

When PDCAM generates a valid control message block, it may not use sequential Cyclic Redundancy Code (CRC) check, coding, modulation, scrambling, etc., but directly use block coding. The code mode generates a valid control message block and then transmits it. For PDCAMs with shorter lengths, the block coding method works better. Since the block coding scheme is a mature prior art, the specific implementation will not be described in detail herein.
