Description

Method and device for transmitting dedicated channel data

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a method, apparatus, and network system for dedicated channel data transmission. Background technique

In the current Universal Mobile Telecommunications System (UMTS) system, the dedicated transmission channel has multiple transmission time intervals (English: Transmission Time Interval, abbreviated: TTI) type, such as 10ms, 20ms, 40ms, 80ms. However, the network side can only configure a TTI length for the user equipment (English: User Equipment, abbreviation: UE) in the cell-specific channel (English: CELL-Dedicated Channel, abbreviation: CELL-DCH). Generally, the larger the TTI, the larger the coverage that the cell can provide. For example, for the cell, the 80ms TTI can provide greater coverage than the 10ms TTI.

For the CELL-DCH state UE, there are two channel types: Dedicated Channel (English: Dedicated Channel, Abbreviation: DCH) and High Speed Packet Access (English: High Speed Packet Access, HSPA) channel. In order to improve the capacity of the cell, in the scenario of the combined service of the DCH and the HSPA, the uplink discontinuous transmission (English: Uplink Discontiguous Transmission, abbreviation: UL DTX) mechanism is introduced, that is, the length of the continuous transmission data of the UE only in the DTX cycle ( The uplink data is transmitted within the DTX burst ), and the uplink data is not transmitted at other locations within the DTX cycle. In some application scenarios, such as Signalling Radio Bearer (abbreviation: SRB) in DCH (English: Signalling Radio Bearer over DCH) and packet service (English: Packet Service, abbreviation: PS) are carried in HSPA (English) : PS over HSPA ) Field of the channel Under the scene, configuring uplink DTX can increase the cell capacity. For example, if the DTX period is

40ms, the DTX burst length is 10ms, then in the absence of data transmission, the UE only sends the uplink dedicated physical control channel within the DTX burst length (ie, 10ms) (English: Dedicated

Physical Control Channel, abbreviation: DPCCH), in the DTX cycle

The uplink DPCCH is not transmitted within other lengths than the DTXburst length (ie, the remaining 30 ms in the DTX period), which can reduce interference to other UEs, thereby increasing cell capacity. Generally, the smaller the DTX burst length in the DTX cycle, the more the cell capacity can be increased. Usually, the DTX burst length is an integer multiple of the TTI length. For example, the TTI length is 10ms, and the DTXburst length can be 10ms, 20ms, and so on.

As mentioned above, in the scenario of DCH and HSPA channel combination services, if the network side is

The UE has a short TTI length. For example, at 10 ms, the UE can enjoy the maximum gain of the uplink DTX, that is, the maximum cell capacity is increased and the terminal energy consumption is saved. However, in a power limited scenario, there is a coverage problem. If the length of the TTI configured by the UE on the network side is longer, such as 40ms or 80ms, the coverage problem can be considered, but the maximum gain of the UL DTX cannot be enjoyed.

FIG. 1 is a flowchart of a method for data transmission provided by an embodiment of the present invention. Referring to FIG. 1, an embodiment of the present invention provides a method for transmitting dedicated channel data, where the method is based on a UE. Said, including:

11. Receive dedicated channel configuration information sent by the RNC.

The dedicated channel configuration information sent by the RNC to the UE in the embodiment of the present invention includes a TTI selection threshold, and may also include a DTX period and the like. The TTI selection threshold is a threshold value when the UE performs the TTI length selection, and can be used to determine the TTI length.

In the embodiment of the present invention, the RNC sends the dedicated channel configuration information to the UE and the base station, so that the UE and the base station can perform data transmission according to the requirements specified by the dedicated channel configuration information.

12. Select a TTI length according to the dedicated channel configuration information sent by the RNC. In the embodiment of the present invention, since the dedicated channel configuration information includes a TTI selection threshold, in this step, according to the dedicated channel configuration information sent by the RNC, selecting a TTI length may include: The TTI selection threshold is used to determine the TTI length. The TTI selection threshold may be one or more, which is not limited by the present invention, and may be selected and set according to requirements.

After acquiring the TTI selection threshold, the UE may determine the TTI length by using various different comparison quantities to compare with the TTI selection threshold. That is, the determining the TTI length according to the TTI selection threshold may specifically include:

Calculate the amount of comparison;

The TTI selection threshold value is compared with the comparison amount to determine a TTI length. The comparison amount in the embodiment of the present invention may be: a power headroom, a transmit power corresponding to a TTI length, and a common pilot. Channel (English: Common Pilot Channel, abbreviation:

CPICH) Received Signal Code Power (RSCP) or CPICH path loss.

The following comparison amounts are the power headroom, the transmit power corresponding to the TTI length, and the CPICH.

The path loss of the RSCP and the CPICH is taken as an example to describe the manner in which the TTI length is determined in the embodiment of the present invention.

1) If the comparison amount is a power headroom, the following manner can be utilized in the embodiment of the present invention. To choose the length of the TTI:

In the scenario where the two TTIs are configured, for example, the configured TTI length is 10 ms and 20 ms, the TTI selection threshold is one. If the power margin is greater than the TTI selection threshold, the first TTI length is selected. (for example, 10ms), otherwise, select the second TTI length (for example, 20ms);

B. In a scenario where two or more TTIs are configured, the TTI selection threshold is multiple, and the corresponding TTI length can be determined by comparing the power margin with the multiple TTI selection thresholds.

The following is an example of configuring four TTI lengths, for example, the configured TTI lengths are 10ms, 20ms, 40ms, and 80ms. In this case, the TTI selection threshold may be a plurality of thresholds including a threshold 1, a threshold 2, and a threshold 3. If the power margin is greater than or equal to the threshold 1, the TTI is selected. 10ms; if the power headroom is less than the threshold value 1 and greater than or equal to the threshold value 2, the TTI is selected to be 20ms; if the power headroom is less than the threshold value 2 and greater than or equal to the threshold value 3, the TTI is selected to be 40ms; If the power headroom is less than the threshold value 3, the TTI is selected to be 80 ms; wherein, in the above two scenarios, the power headroom = min (the maximum transmit power allowed by the uplink, the power supported by the UE itself) - the uplink DPCCH power, or , power margin = min (maximum transmit power allowed by the uplink, power supported by the UE itself) - uplink DPCCH power - uplink HS-DPCCH power. The HS-DPCCH is a Dedicated Physical Control Channel (uplink) for HS-DSCH, and the HS-DSCH is a High Speed Downlink Shared Channel, such as a high-speed downlink shared channel. For example, the power headroom is greater than or equal to 15dB, the UE selects 10ms TTI, and if the power margin is less than 15dB, the UE selects 20ms TTI.

It should be noted that the number of the above threshold values is only an example, and it is of course possible to include two, three or other number of threshold values within the scope of the present invention.

2) If the comparison amount is the transmission power corresponding to the length of ΤΤΙ, the length of ΤΤΙ can be determined by the following method:

If the transmission format determined according to the first transmission length is greater than the selection If the threshold is selected, the second TTI is used, otherwise the first TTI is used. The first ΤΤΙ length is less than the second ΤΤΙ length, for example, the first ΤΤΙ length is 10 ms, and the second TTI length is 20 ms.

The transmit power corresponding to the TTI length is determined according to the transport block length and the control channel power.

For example, the UE first determines a block length by using a 10 ms TTI length to further determine a corresponding transmit power. If the transmit power is greater than 20 dB, a 20 ms TTI length is selected, otherwise a 10 ms TTI length is selected.

It should be noted that the first TTI length and the second TTI length are only an example, and there may be more TTIs, that is, a third TTI length, a fourth TTI length, and the like, and multiple threshold values. Compare to determine the TTI length. In the case where there are multiple TTI lengths, the TTI length needs to be selected in order from small to large, and then the transmit power corresponding to the selected TTI length is compared with the TTI selection threshold, that is, the minimum TTI length is first selected. The transmit power is compared to the TTI selection threshold.

3) If the comparison quantity is CPICH RSCP, the TTI length may be determined by: if the UE detects that the CPICH RSCP is greater than or equal to the TTI selection threshold, then selecting the first TTI length transmission; if the UE detects the CPICH When the RSCP is smaller than the TTI selection threshold, the second TTI length transmission is selected, where the first TTI length is smaller than the second TTI length, for example, the first TTI length is 10 ms, and the second TTI length is 20 ms.

CPICH RSCP refers to the CPICH channel chip received power, which is measured by the UE. For example, if the CPICH RSCP received power is greater than or equal to 10dB, select 10ms TTI, otherwise select 20ms TTI.

It should be noted that the values of the first ΤΤΙ length and the second ΤΤΙ length described herein can be set according to actual conditions according to actual conditions.

4) If the comparison amount is the path loss of CPICH, the TTI length can be determined by the following method:

If the UE detects that the path loss of the CPICH is less than or equal to the TTI selection threshold, the first TTI length is selected; if the UE detects that the path loss of the CPICH is greater than or equal to the ΤΉ The second TTI length is selected, where the first TTI length is less than the second TTI length, for example, the first TTI length is 10 ms, and the second TTI length is 20 ms.

Path loss =. ? 1.11 channel transmit power - CPICH RSCP.

For example, if the path loss is greater than 10 dB, the UE selects 20 ms TTI, otherwise selects 10 ms TTL. It should be noted that the above-mentioned "first TTI length," and "second TTI length, are just an example, and there may be more The TTI length, that is, the third TTI length, the fourth TTI length, and the like, are not limited in the present invention.

It should be emphasized that, in the foregoing various methods for determining the TTI length, the number of TTI selection thresholds and the number of corresponding TTI lengths are only illustrated by way of example, and of course, within the scope of the present invention, Comparing the TTI selection threshold value with the comparison amount, the embodiment of the present invention may further determine the TTI length by using other TTI selection threshold values different from the above number and the corresponding TTI length.

13. Instruct the selected TTI length to the base station.

In this step, the UE may inform the base station of the selected TTI length in different manner by using the TTI length indication information indicating the TTI length. For example, the TTI length may be indicated to the base station by using the TFCI as the TTI length indication information as described below, or a TTI explicit indicator indicating the TTI length may be added to the uplink dedicated physical control channel as described below (ΤΉ length indication) Information) to indicate the TTI length to the base station, so that the base station parses the data in the DPDCH channel according to the indicated TTI length.

14. Transmitting the dedicated channel data to the base station according to the selected TTI length.

It should be noted that the foregoing steps 13 and 14 may occur in parallel. For example, if the UE uses the TFCI in the DPCCH to indicate the TTI length selected by the UE, steps 13 and 14 may occur in parallel, that is, the UE uses DPCCH transmission. TFCI, with the use of DPDCH to send uplink data. The TFCI may be used to indicate the length of the TTI selected by the UE and the transport format selected by the UE.

In the embodiment of the present invention, when the UE performs data transmission with the base station according to the selected length of the TTI, only one data packet may be transmitted in one DTX period, or may be in one Multiple packets are continuously transmitted during the DTX cycle. When the UE transmits only one data packet in one DTX cycle, if there is data in the RLC buffer of the UE, the RLC delivers one data packet to the MAC layer every DTX cycle. When the UE continuously transmits multiple data packets in one DTX period, the UE RLC layer delivers one data packet to the MAC layer every selected TTI length.

The data transmission method provided by the embodiment of the present invention, after receiving the configuration information sent by the RNC, selects a TTI length according to the configuration information sent by the RNC, and indicates the selected TTI length to the base station, and then according to the configuration. The selected TTI length is transmitted with the base station for data transmission. Since the TTI length is actively selected by the UE, rather than being specified by the network side, the UE can flexibly perform TTI length selection in combination with its own power limited condition. When the power is not limited, a shorter TTI can be selected. Length, when power is limited, a longer TTI length can be selected, thereby enabling both UL DTX gain and UL coverage to be maximized to maximize UL DTX gain and extend UL coverage.

In an embodiment of the present invention, the dedicated channel configuration information further includes a first transport format set, where the first transport format set includes at least one transport format, and each of the transport formats includes at least the following transmission Format information: RLC size and TTI length. After the TTI length is selected according to the configuration information sent by the RNC, the method further includes: determining, according to the first transport format set, a TFCI of a transport format corresponding to the selected length of the ΤΉ . The TFCI indicates the length of the TTI selected by the UE, that is, the length of the TTI selected by the UE may be determined according to the value of the TFCT. At this time, the indicating the selected TTI length to the base station in the step 13 includes: transmitting the determined TFCI corresponding to the TTI length to the base station, so that the base station determines the corresponding transmission format according to the TFCI. The TTI length, and parses the received uplink dedicated channel data.

It should be noted that the transmission format is configured based on a transport channel, and the network configures at least one transport channel for the UE, and each transport channel corresponds to at least one transport format. When the UE transmits data, it can transmit data combination of multiple transport channels. For example, if the network configures two transport channels DCH1 and DCH2 for the UE, and the transmission format corresponding to DCH1 is TF11 (RLC size = 160 bits, number of transport blocks is 1, TTI is 10 ms), TF12 (RLC size = 160) Than Specifically, the number of transport blocks is 1, TTI is 20ms), and the transport format corresponding to DCH2 is TF2 RLC size = 240 bits, the number of transport blocks is 1, ΤΤΙ is 10 ms, TF22 (RLC size = 240 bits, number of transport blocks) 1 , TTI is 20 ms), in this embodiment, TFCI0 can be (TF11, 0), TFCI1 can be (TF12, 0), TFCI2 can be (TF11, TF21), TFCI3 can be (0, TF21 ), TFCI4 can be (0, TF22), and TFCI5 can be (TF12, TF22). The TFCI0 is (TF11, 0), indicating that the UE only transmits the data of the DCH1, and the used RLC size is 160 bits and the TTI length is 10 ms, and the TFCI2 is (TF11, TF21), indicating that the UE simultaneously transmits the data of the DCH1 and the DCH2, and The amount of data transmitted on the DCH1 channel is 160 bits, the data amount of the DCH2 channel is 240 bits, and the length of the used TTI is 10 ms. As the first transport format set is configured by the RNC to the base station and the UE, it can be seen from the above example that the base station can determine the TTI length and the transport format selected by the UE based on the TFCI.

In this embodiment, each transport format may specifically include the following three transport format information: RLC size, number of transport blocks, and TTI length, but are not limited thereto.

Specifically, the transport format information in this embodiment may be as follows:

Among them, " >, in the above table, indicates a hierarchical relationship, such as a " >," means the first level, two " >," means the second level under the first level, three " >, , which represents the third level under the second level.

In this manner, a TTI explicit indicator is added to the uplink physical control channel sent to the base station, where the TTI explicit indicator indicates the length of the TTI selected by the UE, so that the base station explicitly displays according to the TTI. The indicator can determine the corresponding TTI length and parse the uplink dedicated channel data according to the determined TTI length.此种 Use this TTI explicit indicator to directly inform the base station of the TTI length.

In a further embodiment of the present invention, the dedicated channel configuration information includes a second transmission format set, where the second transmission format set includes at least A transmission format, each of which includes at least two transmission format information of an RLC size and a number of transmission blocks, but does not include the following transmission format information: TTI length. The dedicated channel configuration information may further include a TTI length set, where the TTI length set includes at least one TTI length. After the TTI length is selected according to the dedicated channel configuration information sent by the RNC, the method further includes: determining, according to the second transport format set, a transport format corresponding to the selected TTI length. TFCI. After determining the ΤΉ and TFCI, the UE sends the selected TFCI and TTI explicit indicator to the base station through the uplink dedicated physical control channel, so that the base station according to the TFCI And the TTI explicit indicator determines a transport format and a TTI length used by the UE DPDCH channel, and parses the DPDCH data according to the transport format and the TTI length.
