Description

Semi-static scheduling data processing method, terminal and system

[1] This application claims priority to Chinese Patent Application No. 200810198704.9, entitled "Terminal, Semi-Static Scheduling Data Processing Method and System", filed on September 23, 2008, the entire contents of which are hereby incorporated by reference. The citations are incorporated herein by reference.

[2] Technical field

[3] The present invention relates to communication technologies, and in particular, to a semi-persistent scheduling data processing method, a terminal, and a system.

[4] Background of the invention

[5] LTE (Long Term

Evolution, long-term evolution) In the system, there are two types of resource scheduling, one is dynamic scheduling, and the other is semi-persistent scheduling.

Scheduling). Dynamic scheduling refers to eNB (evolved Node)

B, evolved node) There is no fixed restriction on the scheduling of resources. When data arrives, the eNB allocates resources and performs data transmission. Semi-persistent scheduling means that the scheduling of resources is periodic. For example, VoIP services are scheduled once every 20 m s. Therefore, the eNB can allocate resources in advance, and the allocated resources are periodically used. Semi-persistent scheduling resources are only used for initial transmission, that is, data transmission for semi-static scheduling engraving only.

[6] Measurement gap refers to the terminal (User

Equipment, UE) The measurement of the inter-turn length due to the need for measurement and normal data transmission and reception. If semi-static scheduling initial transmission gap and measurement gap (Measurement

Gap), in particular, when the eNB learns from the configuration information of the terminal that the terminal is in the measurement gap and conflicts with the semi-persistent scheduling initial transmission gap, the eNB stops the semi-persistent scheduling initial transmission, and after the measurement gap, Retransmitting the initial transmission data; or the eNB does not stop the semi-persistent scheduling of the initial transmission, but the UE is in the measurement gap and does not receive the semi-persistent scheduling initial transmission data of the eNB, so the eNB also retransmits the initial transmission data.

[7] For dynamic scheduling, via NDI (New Data

Indicator, new data indication) Whether to change to determine whether it is new data, when the NDI changes, recognize In order to be a new data transmission, otherwise it is considered to be retransmitted data. When the eNB retransmits the initial transmission data after the measurement gap of the terminal, since the NDI of the retransmitted data is different from the previous transmitted NDI, after the UE receives the NDI, It compares with the NDI value of the previous transmission saved by itself, and finds that the NDI has changed, so the first retransmission data is treated as new data, so that normal processing can be performed.

[8] For semi-persistent scheduling, the processing of NDI is different. In the initial transmission of semi-persistent scheduling, the NDI is fixed to 0, and the retransmission data is fixed to 1, which is semi-static scheduling. The NDI is 1, and the UE judges whether it is new data or retransmitted data according to the NDI transmitted by the eNB. If the ND I received by the terminal is 1, it is determined to retransmit the data, so when the eNB is in the measurement gap of the terminal, After retransmitting the initial transmission data, the NDI is set to 1, and the UE treats the retransmission initial transmission data as retransmitted data, and does not treat it as new data.

[9] In the process of implementing the present invention, the inventors found that: the measurement is periodic, and the semi-static scheduling is also periodic, and the semi-static scheduling occurs in a fixed gap, and the measurement gap and the semi-static scheduling gap are very A conflict may occur. The initial transmission gap between the semi-persistent scheduling and the measurement gap of the terminal may cause the initial transmission failure of the semi-persistent scheduling. When the eNB transmits the initial transmission data again after the measurement gap of the terminal, the terminal determines that it is retransmitted data and performs Hybrid automatic retransmission of data in the request buffer for merging operation, which will cause the UE to decode the data and cause data loss.

[10] Summary of the invention

[11] The present invention provides a semi-persistent scheduling data processing method, a terminal, and a system, which can solve the problem that the initial retransmission data of the semi-persistent scheduling is error-processed by the UE for the semi-persistent scheduling initial transmission gap and the measurement gap conflict. Problem, can improve the decoding rate.

[13] The terminal clears the data in its hybrid automatic repeat request buffer, and writes the semi-persistent scheduled first retransmission data received after the measurement gap to the hybrid automatic repeat request buffer, the measurement The gap conflicts with the initial transmission gap of the semi-static scheduling;

[14] Decoding the semi-persistently scheduled first retransmission data of the hybrid automatic repeat request buffer.

[15] Correspondingly, an embodiment of the present invention further provides a terminal, including:

[21] When the initial transmission gap between the semi-persistent scheduling and the measurement gap of the terminal causes the initial transmission of the semi-persistent transmission to fail, the eNB retransmits the initial transmission data after the measurement gap of the terminal, and the terminal first buffers the automatic retransmission request. The data in the area is emptied, and then the semi-statically scheduled first retransmission data is written into the hybrid automatic repeat request buffer, so that erroneous merging of data in the hybrid automatic repeat request buffer can be avoided.

[33] The present invention provides a semi-persistent scheduling data processing method, a terminal, and a semi-persistent scheduling data processing system, which solves the problem that the initial retransmission data of the semi-persistent scheduling is misprocessed by the UE due to the collision between the initial transmission gap and the measurement gap of the semi-persistent scheduling. Technical problem.

[34] First, it should be noted that the semi-persistent scheduling engraving described in this embodiment refers to the initial transmission of semi-static data in the engraving, and the semi-persistent scheduling period passes through RRC (Radio Resource).

Configuration, Radio Resource Configuration) Configure, for example, for VoIP (Voice over IP, IP-based voice transmission) with a period of 20ms. The specified resources include a modulation and coding scheme, a radio bearer resource, and the like. Semi-persistent scheduling through SPS-RNTI (Semi-Persistent Scheduling-Radio Network Temporary

Identifier, semi-persistent scheduling wireless network Linyi identifier) scrambled PDCCH (Physical Downlink Control

Channel, physical downlink control channel) is activated. After activation, the PDCCH is not sent for indication in semi-persistent scheduling, unless the semi-persistent scheduling resource needs to be reconfigured, and the UE performs the semi-static scheduling engraving according to the configured resources. Data reception. The measurement gap of the UE is also configured first. When the measurement gap of the terminal conflicts with the initial transmission of the semi-persistent scheduling, the eNB may decide whether to schedule the initial transmission data to the UE according to its implementation.

[35] Referring to Figure 1, there is shown a flow chart of the method of the first embodiment of the present invention. The semi-persistent scheduling data processing method in this embodiment includes:

[36] When the measurement gap of the terminal conflicts with the initial transmission of the semi-persistent scheduling, the terminal does not receive the semi-statically scheduled initial transmission data, and after the measurement gap of the terminal, the eNB retransmits the semi-persistent scheduling initial transmission to the UE. The initial transmission data that is not received by the terminal, the first retransmission data of the semi-persistent scheduling referred to in this embodiment refers to the initial transmission of the semi-persistent scheduling initial transmission that the eNB retransmits to the UE for the first time and is not received by the terminal. Data

[37] Step 100: The terminal clears the data in the hybrid automatic repeat request buffer, and writes the semi-persistent scheduled first retransmission data received after the measurement gap to the hybrid automatic repeat request buffer. [38] Step 101: Decode the first retransmission data of the semi-persistent scheduling in the hybrid automatic repeat request buffer. [39] It should be noted that, after the UE decodes the first retransmitted data, the decoding may be successful, or the decoding may fail. When the decoding fails, the UE returns the result of the decoding failure to the eNB, and the eNB sends the UE to the UE. The second retransmission data is sent, and the UE processes the subsequent retransmission data in the same manner as the prior art, that is, the UE directly receives the second retransmission data and directly performs semi-persistent scheduling in the HARQ (Hybrid Automatic Repeat Request) buffer. The first retransmission data is merged, then decoded, and retransmitted until the decoding is successful or the maximum number of transmissions is reached.

[40] When the initial transmission gap of the semi-persistent scheduling conflicts with the measurement gap of the terminal, the initial transmission failure of the semi-static scheduling is lost.

After the eNB retransmits the initial transmission data after the measurement gap of the terminal, the terminal first clears the data in the hybrid automatic retransmission request buffer, and then writes the semi-persistently scheduled first retransmission data into the hybrid automatic repeat request. Buffers, so you can avoid erroneous merging of data in the hybrid auto-request request buffer.

[41] Figure 2 is a schematic diagram of the semi-static scheduling initial transmission gap and measurement gap conflict.

[42] At least one HARQ process (Hybrid Automatic Repeat request) is reserved for semi-persistent scheduling on the LTE downlink.

Process , hybrid automatic repeat request process), as shown in Figure 2, assumes that 2 HARQs are reserved.

Process , and the reserved process is bound to the LTE frame number for alternate use. For the same HARQ process (such as process

1), its static scheduling initial transmission engraving interval is 40ms. Before the measurement gap of the terminal, process 1 successfully completes the semi-static scheduling initial transmission, 40 ms later, process

1 is used again for the semi-persistent scheduling initial transmission. Since the UE is in the measurement gap, the UE does not receive the initial transmission data of the engraved semi-persistent scheduling. After the measurement gap, the eNB retransmits the semi-persistent scheduling data for the first time. The NDI of the retransmission is set to 1. The semi-persistent scheduling data processing method in this embodiment is specifically referred to FIG. 3 and FIG. 4, which will be described in detail below.

[43] Referring to FIG. 3, it is a schematic flowchart of a method according to a second embodiment of the present invention. The semi-persistent scheduling data processing method of this embodiment is as follows:

[44] Step 200: After initial transmission of the semi-persistent scheduling, the eNB fixed the NDI to 0, and performs semi-static scheduling initial transmission to the UE. [45] Step 201, the UE is in the measurement gap, so the UE cannot receive the initial transmission data, and then the UE clears the data of the HARQ buffer used to process the semi-persistent scheduled initial transmission data;

[46] Step 202: After measuring the gap, the eNB sends a semi-persistently scheduled first retransmission data to the UE, where the eNB uses the SPS-RNTI to scramble the PDCCH. Because the semi-persistent scheduling retransmits data, the eNB will NDI is set to 1;

[47] Step 203: Since the NDI is set to 1, the UE determines that the data is a semi-persistent scheduling retransmission data;

[48] Step 204: The UE writes the first retransmission data that it receives the semi-persistent scheduling to the H that empties the data.

An ARQ buffer, and decoding the semi-statically scheduled first retransmission data in a HARQ buffer.

[49] Step 205: The UE feeds back the decoding result to the eNB, and the eNB determines, according to the decoding result, whether the semi-persistent scheduling data needs to be retransmitted again.

[50] In this embodiment, after the UE collides with the semi-persistent scheduling initial transmission gap, the UE first clears the data in the HARQ buffer, and then receives the semi-persistent scheduled first retransmission data received after the measurement gap. The HARQ buffer is written, so the semi-persistently scheduled first retransmission data is not erroneously merged with the data in the HARQ.

[51] Referring to FIG. 4, it is a schematic flowchart of a method according to a third embodiment of the present invention. The semi-persistent scheduling data processing method of this embodiment is as follows:

[52] Step 300: After initial transmission of the semi-persistent scheduling, the eNB fixed the NDI to 0, and performs semi-static scheduling initial transmission to the UE.

[53] Step 301: The UE is in the measurement gap, so the UE cannot receive the initial transmission data, and the UE is the semi-persistent scheduling HARQ that receives the initial transmission data in the initial transmission slot of the semi-persistent scheduling.

The process sets the conflict flag. It should be noted that the UE may set the conflict flag by adding a flag to indicate that the semi-persistent scheduling initial transmission gap conflicts with the measurement gap, or may also assign a value to the conflict flag, for example, 1, indicating that the initial transmission gap of the semi-persistent scheduling conflicts with its measurement gap, and when the collision flag is assigned 0 or the content is empty, it indicates that the initial transmission gap of the semi-persistent scheduling does not conflict with its measurement gap.

[54] The collision flag is set for each semi-persistently scheduled HARQ process. For the same HARQ process, the collision flag is cleared by the UE in the next semi-persistent scheduling initial transmission, unless the next semi-static scheduling initial transmission There is a conflict again. The manner in which the UE clears the conflict flag may be the rush The flag is deleted, or the content of the conflict flag can be cleared or restored to the default value of 0.

[55] Step 302: After measuring the gap, the eNB sends a semi-persistently scheduled first retransmission data to the UE, where the eNB uses the SPS-RNTI to scramble the PDCCH. Since the semi-persistent scheduling retransmits the data, the eNB will NDI is set to 1;

[56] Step 303, since the NDI is set to 1, the UE determines that the data is semi-persistently scheduled to retransmit data;

[57] Step 304, the UE checks the HARQ that receives the first retransmission data.

The conflict flag of the process, if the conflict flag is set, the UE clears the data in its HARQ buffer;

[58] Step 305: The UE writes the first retransmission data that it receives the semi-persistent scheduling into the H ARQ buffer that clears the data, and decodes the semi-statically scheduled first retransmission data in the HARQ buffer. ;

[59] It should be noted that, after checking that the conflict flag is set, the UE may directly cover the data in the HARQ buffer by using the semi-persistently scheduled retransmission data received by the UE;

[60] After the first retransmitted data is written into the HARQ buffer that empties the data or directly covers the data in the HARQ buffer, the UE will HARQ

The process's conflict flag is cleared, and subsequent semi-persistent scheduling retransmissions are directly merged with the data in the HARQ buffer.

[61] If the UE is HARQ

The process sets the conflict flag, but until the next semi-static scheduling, the UE does not receive the semi-persistent retransmitted data, and the UE will clear the conflict flag at the initial semi-static scheduling initial, unless the next semi-persistent scheduling The initial transfer conflicts again.

[62] Step 306: The UE feeds back the decoding result to the eNB, and the eNB determines, according to the decoding result, whether the semi-persistent scheduling data needs to be retransmitted again.

[63] In this embodiment, the UE firstly receives the semi-persistent scheduling HARQ of the initial transmission data in the initial transmission gap of the semi-persistent scheduling after the measurement gap conflicts with the semi-persistent scheduling initial transmission gap.

The process sets the conflict flag, and after receiving the first retransmission data of the semi-persistent scheduling after the measurement gap, first clears its HARQ buffer, and then writes the semi-persistent scheduled first retransmission data received after the measurement gap to the HARQ. Buffer, so the first retransmission of the semi-persistent data will not be merged with the data in HARQ. [64] Referring to FIG. 5, it is a schematic structural diagram of a system according to a fourth embodiment of the present invention. The system in this embodiment includes

[65] Terminal 1, after the measurement gap conflicts with the semi-persistent scheduling initial transmission gap, or after receiving the semi-statically scheduled first retransmission data after the measurement gap, mixes the data in the automatic retransmission request buffer. Emptying, and writing the semi-persistently scheduled first retransmission data received after the measurement gap to the hybrid automatic repeat request buffer, the semi-static scheduling of the hybrid automatic repeat request buffer for the first time Retransmit the data for decoding.

[66] It should be noted that, after the UE1 decodes the first retransmitted data, the decoding may be successful, and the decoding may fail. When the decoding fails, the UE returns the result of the decoding failure to the eNB, and the eNB sends the UE to the UE. Sending the second retransmission data, the UE processing the subsequent retransmission data is the same as the prior art, that is, the UE directly merges with the semi-persistently scheduled retransmission data in the HARQ after receiving the second retransmission data. Then decode until the decoding is successful.
