"Happy" bit reflects the UE for uplink packet scheduling Node B fast results "satisfactory
Degrees "on the Node B control fast uplink packet scheduling with auxiliary role. According to 3GPP specifications
TS25.321, if the UE has sufficient transmit power in the case, the total current E-DCH data sent

Authorization (Serving Grant, referred to "SG") but can not complete the send, it will "Happy" bit
Is set to "Unhappy"; or "Happy" bit is set to "Happy".
This 10-bit information via second Reed Male (Reed-Muller) code for the channel coding,
30 bits, formed, for 2ms TTI mode 30 after the encoded bits in the E-DPCCH is
A 2ms sub-frame for transmission; for 10ms TTI mode, the encoded bits after 30
In the E-DPCCH frame is a 10ms 2ms sub-frame 5 at the same time (that is repeated 5 times) pass
Lose. E-DPCCH/E-DPDCH frame format shown in Figure 1, E-DPCCH in a 10ms frame packet
With 15 slots, each time slot 3 a 2ms sub-frame, i.e. a 10ms frame includes 5 2ms
Sub-frame. The E-DPCCH slot format shown in Table 1.
| Slot Format # i # i slot format | Channel Bit Rate (kbps) Channel bit rate (one thousand Bits per second) | SF Spreading factor | Bits / Frame Bits / frame | Bits / Subframe Bits / sub-frame | Bits / Slot
Bits / |
| 0 | 15 | 256 | 150 | 30 | 10 |
Table 1
It can be seen, each slot can transmit E-DPCCH 10 bits, a sub-frame may 2ms
Transfer 30 bits.
In the E-DCH and HSDPA, because the HARQ operation, thus the bit error rate than the physical layer
Other high transmission channel, and, E-DCH and HSDPA are often large transport block transmitted to 2ms
For example an E-DCH TTI, the maximum transport block size of 11484 bits.
Communication is often used in a cyclic redundancy check (Cyclic Redundancy Check, referred to "CRC")
Code to detect the transmitted data block is correct, for example, in the ITU-T recommendation of 2048kbit / s (kilobits
Special sec) of PCM (Pulse Code Modulation, Pulse Code Modulation)-based equipment used in group
With a length of 4 CRC, wherein the CRC code with generator polynomial gCRC4(D)＝D
4+
D
1+1. According to a cyclic redundancy check (Cyclic Redundancy Check, referred to "CRC") of the original
Li, CRC checksum to detect 100% of all odd random bit errors, even almost all
A random number of bit errors, and the length is less than or equal to n consecutive bit errors (also called burst error
SE), where n is the order of the CRC generator polynomial.
In 3GPP, the addition to the HSDPA and E-DCH transport channel outside, 3GPP specifications
TS 25.212 length allows the use of the CRC bits are 24,16,12 and 8, the specific use of the CRC
Length is determined by the radio resource control (Radio Resource Control, abbreviated "RRC") semi-static transfer
Information elements of transport format information (Information Element, abbreviated "IE") determined.
Also according to the 3GPP specification TS 25.212, the transmit side MAC-e PDU into the physical layer
After the first attach a 24-bit CRC, the transport block prior to the HARQ process block error rate (Block
Error Rate, referred to as "BLER") high, in order to reliably detect transmission errors, the use of
Order of 24 of the CRC to reduce the probability of false negative errors. Then the channel coding, interleaving and Star
Block diagram mapping operations.
However, there is no need to transmit user data transmission SI separate case:
(1) UE Node B is not allowed to send data state control, namely SG parameters
"Zero_Grant" or all HARQ processes are in a non-active state;
(2) UE Node B is allowed to send data to the control state, that SG parameter is not equal to
"Zero_Grant" and at least one HARQ process is active, but in a non-active HARQ
Process and in the active HARQ processes certain TTI corresponding buffer has no data to send
Send.
In these cases, too, the individual 18-bit in the SI transmitted in the physical layer 24 to form a
Bit CRC code, and then by channel coding, interleaving and constellation mapping operation finally
E-DPDCH transmission.
In practical applications, the above scheme has the following problem: UE is in a separate wireless link transmission SI
Performance is poor.
The main reason for this situation, because after the CRC after the physical layer transmission block
Interleaving process, when the transport block is large consecutive higher bit error probability, the higher
The CRC coding order of consecutive bits can be detected errors, but for a separate 18-bit transfer
SI reported cases, 24-bit vs. 18-bit CRC SI is still long, leading to increased CRC itself
SI transmission BLER, while the wireless transmission efficiency is low, and thus the capacity of the uplink with a
The limits specified.

Figure 2 is a first embodiment of the present invention, E-DCH transmission method in a flowchart of SI.
Specific embodiments
The object of the present invention, technical solutions and advantages more clearly below with reference to the present
Ming as described in further detail.
The present invention is a single SI of reports transmitted in the physical layer channel coding and multiplexing, allowing the
Less than 24 bits using a CRC code checksum reported as SI, which, CRC coding order to
Thought 16,12,8 or 4. On the order of 16, 12 or 8 for CRC coding, by the corresponding
TS 25.212, respectively, given the generator polynomial is as follows:
g
CRC16(D)＝D
16+D
12+D
5+1；
g
CRC12(D)＝D
12+D
11+D
3+D
2+D+1；
g
CRC8(D)＝D

7+D
4+D
3+D+1。
Order of 4 to CRC coding, the generating polynomial is as follows:
g
CRC4(D)＝D
4+D
1+1
In addition to individual transport in the SI report can be fixed using the order number one 16,12,8 or 4 of the CRC
In addition, it allows high-level protocols such as RRC, NBAP, RNSAP such flexibility to configure individual transport SI
Reporting the E-DCH transport block CRC of the order. In this way, the UE is in a separate transmission SI,
CRC coding can reasonably selected length, so long as a result of the CRC coding SI transmission BLER
Increase. And, in a separate transmission SI short length used when the CRC coding, wireless transmission efficiency improves
Rate, thereby effectively reducing the uplink interference system, help to optimize the uplink capacity of the system.
A first embodiment of the present invention, an E-DCH in the SI transmission method shown in Figure 2, UE and Node B
According to the agreement fixed settings of the CRC for a separate order for CRC coding SI transmission, the order less than 24,
4,8,12, or 16 for one.
In step 201, according to the current protocol version, SI reported Ks = 18 bits in length. Accordingly,
In the MAC layer MAC-e PDU into the physical layer, UE needs to transmit that determine the size of the transport block,
The MAC-e PDU size is 18 bits, and if it is, the transport block is a single transmission SI,
Go to Step 202; otherwise the transport block for a non-single transport block transmitted SI,, proceeds to step 203.
In step 202, UE using the protocol of the CRC fixed settings for individual transmission order of the CRC SI
Encoding, for example, the order number is set to 8.
In step 203, UE 24 using the CRC order SI transmission of non-single transport block is encoded.
In step 204, the transport block CRC encoded added, UE specified by TS25.212
Process for the transmission block for channel coding, interleaving and constellation mapping and other operations, and then send the transport block
To Node B.
In step 205, Node B fixed under the agreement set, the received transmission SI separate transmission
With this order of less than 24 blocks fixed set the order of the CRC detection, for example, the UE in step 202
Used to set the order of 8, according to the setting, Node B using the same order of CRC code is 8;
Node B for separate transmission received from non-SI transmission block 24, based on existing technology uses the CRC-order
Testing.
The second embodiment of the present invention, an E-DCH in the SI transmission method in the first embodiment is basically the same,
The only difference is that, by adding a new RRC IE "CRC Size for Standalone Scheduling
Info (CRC alone scheduling information size) "is used to indicate the physical layer transmission order of use of the CRC,
SI transmitted in a separate case, the report may be the order of 8, 12 or 16. And, UE through RRC
IE message carrying the new Node B by the advance notice of the order of CRC used in the E-DPDCH single
Independent Transmission SI report, Node B according to the RRC message transmitted with the UE using block CRC coding
The same order of the CRC of the received transport blocks for testing.
Specifically, in the RRC protocol, defines a description of E-DPDCH channel parameters IE
"E-DPDCH Info (E-DPDCH Info)" shown in Table 2, which contains the "Scheduling
Information Configuration (scheduling information Configuration) "in IE TS25.331 the RRC under the existing agreement
Yee, describes the E-DPDCH transmission parameters associated wireless SI: "Periodicity for Scheduling
Info-no grant (scheduling information cycle - non-authorized) "," Periodicity for Scheduling Info-grant (tune
Degree of information lifecycle - authorization) "and" Power Offet for Scheduling Info (scheduling information power offset). "
Will add IE "CRC Size for Standalone Scheduling Info" to add the IE "Scheduling
Information Configuration ", add the IE type (Need) is mandatory (Mandatory Present,
Abbreviation "MP"), which ranges from integer 0,4,8,12,16 or 24. This allows the RNC
For creating, modifying, and other E-DPDCH channel operation at the same time, the flexibility to specify the E-DPDCH transmission alone
SI input of the CRC used when reporting the order of, for example, typically of the order of l6, 12,8 or 4.
