Description

Method, device and system for processing high-speed data transmission
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method for processing high-speed data transmission, and a corresponding apparatus and system.
Background
In a WCDMA system, User Equipment (UE) effects data transmission through a base station, such as a node b (nodeb).
When high-speed data is transmitted, because the positions of the UEs relative to the NodeB are different, the interaction time with the NodeB through the channel is also different, so that signals received at a receiver of the NodeB are misaligned, that is, the signals of the UEs are not completely orthogonal, so that the signals of the UEs interfere with each other, thereby reducing the receiving performance of the NodeB.
In order to minimize signal interference between UEs, a current solution is to use a Synchronous Enhanced Dedicated Channel (SEDCH), which mainly uses multiple UEs to use the same scrambling code and different channelization codes to improve the orthogonality of signals received by the NodeB side. And the channelization codes are typically OVSF codes.
In the process of implementing the invention, the inventor finds that:
the scheme using the SEDCH can reduce signal interference among the UEs, but the scheme requires that a plurality of UEs use the same scrambling code and use different channelization codes for different UEs, and the number of the channelization codes corresponding to the same scrambling code is limited, so that the requirement on orthogonal spread spectrum code (OVSF) resources as the channelization codes is higher when the number of the UEs is large, and the UEs cannot transmit high-speed data possibly due to insufficient OVSF code resources.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
The embodiment of the invention mainly sets the Time division multiplexing (TDM scheduling) for the user transmitting the high-speed data, and schedules the user transmitting the high-speed data among different Transmission Time Intervals (TTI) according to the setting.
Specifically, in this embodiment, first, TDM scheduling needs to be performed on the UE, the scheduling information corresponding to the UE is determined according to the setting, and a channel for transmitting the corresponding scheduling information needs to be added, and then, the network side may send the scheduling information set for the UE to the UE through the set channel.
Accordingly, the UE may determine whether high-speed data transmission is possible according to the received scheduling information.
According to the scheme for enabling the UE to send the high-speed data according to the scheduling information, the signals sent by the UE needing to transmit the high-speed data can be basically orthogonal in time, so that signal interference among the UE is reduced to the minimum, and the receiving performance of the NodeB is improved. Moreover, a plurality of UEs in the above embodiment may use different scrambling codes, so that there is no special requirement for OVSF resources, and the situation that the UE cannot transmit high-speed data due to insufficient OVSF code resources does not occur.
In the above embodiment, the setting of the scheduling information may specifically be setting a control command value, and when the control command value is set, a different value may be set to indicate whether the UE is scheduled in the next scheduling granularity, for example, 1 may be set to indicate that the UE is scheduled in the next scheduling granularity, and 0 indicates that the UE is not scheduled. Thus, when the UE obtains the control command value of 1, the UE is determined to be capable of transmitting high-speed data; and when the control command value of 0 is obtained, determining that the UE stops transmitting the high-speed data.
In the above embodiment, TDM scheduling is performed on the UE, so that a plurality of UEs can perform high-speed data transmission in different scheduling periods, and the scheduling granularity may be K TTIs. The K value may be configured by the network side, and the high speed data transmission frequency of the UE may be controlled by configuring the K value. The K value may be sent to the UE by the network side through a message, or the K value may be configured in advance at the UE side. The first two rows of fig. 1 correspond to the TDM patterns in the case where the K value is set to 1, and the second two rows of fig. 1 correspond to the TDM patterns in the case where the K value is set to 2.
In addition, the TTI may be specifically set as needed. For example, it may be set to 2ms, and each TTI corresponds to 3 timeslots; it can also be set to 10ms, corresponding to 12 slots per TTI.
In the above embodiment, a channel for transmitting corresponding scheduling information is added, specifically, a dedicated channel may be added, or a common channel may be added. The same point between the two is that both the scheduling information, i.e. the control command value in the present embodiment, needs to be sent to the UE.
If a common channel is added, the control command value can be sent to the UE together with the ID of the UE, so that the UE can acquire the control command value related to the UE.
If a dedicated channel is added, the specific implementation scheme based on the dedicated channel is as follows:
dedicated channels are configured and signaling sent to different UEs is distinguished by using different control command values and setting different orthogonal sequences. Here, and in the following embodiments, the scheduling information is a control command value as an example, and of course, the scheduling information may be set otherwise.
For example, a new dedicated Channel, i.e., Enhanced Scheduling Indicator Channel (E-SICH) may be set.
When the network side sends the corresponding scheduling information to the UE through the dedicated channel, the scheduling information may be specifically sent according to the orthogonal sequence. For example, the control command value for scheduling high-speed data transmission is multiplied by the Hadma sequence, and the resulting data bit b isi，jCarried on the E-SICH channel. Assuming that the control command value is a,b is the multiplication of the control command value by the Hadma sequencei，jCan be expressed by the following formula:
bi，j＝a Css，40，m(i)，j
for the above processing, using 2ms TTI corresponding to 3 slots as an example, C used for multiplying each slot when performing the operation of multiplying the control command value by the Hadma sequencess，40，m(i)，jThe method can be determined by means of hopping, for example, the mode shown in the following table 1 can be used. If the TTI is the TTI corresponding to 12 time slots, the processing mode of the previous TTI is repeated for 4 times. Here, taking the example of multiplying the control command value by the Hadma sequence and adopting a hopping method, it is obvious that other similar methods can be adopted as long as the purpose of data processing on the control command value can be achieved.
Figure A200810065357D00131
TABLE 1
Then, the network side needs to process the data on the E-SICH channel and the data carried on other dedicated channels to form a wireless signal and send out the wireless signal. Wherein the other channels may be dedicated channels such as an Enhanced Relative Grant Channel (E-RGCH) and an Enhanced Hybrid ARQ Indicator Channel (E-HICH), and the process in this case is shown in fig. 2. The processing may specifically include:
and step A, carrying out data combination operation, specifically an addition operation, on the data bits carried on the E-SICH channel and the data on other channels.
And step B, performing spread spectrum processing, specifically, multiplication, on the data combined in step 1 and the OVSF code allocated to the UE by the network side.
And step C, processing the spread data into a wireless signal and transmitting the wireless signal, wherein the processing specifically comprises scrambling, pulse shaping and the like.
Accordingly, after receiving the radio signal, the UE processes the radio signal to obtain the control command value sent by the network side. Taking the aforementioned control command value as an example, if the obtained value is 1, it indicates the next K TTIs, and the UE can perform high-speed data transmission; otherwise, the user cannot perform high-speed data transmission.
In addition, the UE may not always maintain the transmission of the high speed data, for example, the UE may continue to transmit the high speed data for a certain period of time, and change to transmit the low speed data for another period of time. Or vice versa. For this case, when initially establishing the configuration, the orthogonal sequence may be directly configured for each UE capable of transmitting high-speed data, regardless of whether the UE is currently transmitting high-speed data or low-speed data.
Certainly, in order to save the resources of the orthogonal sequence, a resource pool of the orthogonal sequence may be further set on the network side, and when the network side determines that the UE is transmitting high-speed data, the orthogonal sequence is selected for the UE from the resource pool of the orthogonal sequence, and the related information of the orthogonal sequence is sent to the UE.
After the orthogonal sequence resource pool is set, the number of the orthogonal sequence in the resource pool can be indicated, a sequence subset is selected from the resource pool, and the sequence subset is sent to the UE in a broadcast mode. And then, when the network side determines that the UE transmits high-speed data, selecting an orthogonal sequence for the UE from the sequence subset, and sending the number of the orthogonal sequence to the UE. When transmitting the number, the number may be transmitted using an order command of a High Speed shared Control Channel (HS-SCCH).
Thus, for the scheme of setting the orthogonal sequence resource pool, if the network side finds that a certain UE is transmitting high-speed data, the NodeB may inform the UE of the currently used orthogonal sequence through the above two ways. The control command value may then be sent to the UE along with other data. In this way, after obtaining the control command value and the orthogonal sequence, the UE can perform a normal scheduling procedure.
In addition, the network side may send, to the UE, not only information related to the orthogonal sequence allocated to the UE, but also a command to prohibit the UE from using the orthogonal sequence. And the order can also be sent in the order mode of the HS-SCCH channel, and of course, other modes can also be used for sending the order.
In the embodiment, the TDM scheduling is set for the UE, the corresponding scheduling information for controlling the UE to transmit the high-speed data is determined according to the setting, the channel for transmitting the scheduling information is set, and the scheduling information is sent to the UE through the set channel, so that the UE can send the high-speed data according to the scheduling information, and thus, signals sent by the UE needing to transmit the high-speed data can be guaranteed to be basically orthogonal in time, so that signal interference between the UEs is reduced to the minimum, and further, the receiving performance of the base station is improved.
In addition, the scheme of setting the orthogonal sequence resource pool in the embodiment of the invention can further save the orthogonal sequence resources and effectively avoid the problem of orthogonal resource waste.
Based on the above setting for the network side, the UE side in the embodiment of the present invention can implement transmission of high-speed data, and specifically, as shown in fig. 3, the following steps are implemented correspondingly:
step 301, the UE receives data sent by the network side;
step 302, the UE parses scheduling information sent by the network side from the received data;
and 303, determining whether the UE can currently perform high-speed data transmission according to the analyzed scheduling information, that is, whether the network side is currently allocated to the UE for high-speed data transmission for the k TTIs, if so, performing high-speed data transmission, otherwise, not performing high-speed data transmission.
As mentioned above, the parsed scheduling information may be a control command value, and the details of the control command value are not described herein again.
If the network side sends the scheduling information to the UE by setting the common channel, in step 302, the UE obtains the data sent to the UE from the data sent by the common channel, and obtains the scheduling information from the obtained data. The network side may carry the ID of the UE in the data sent through the common channel, so that the UE may determine the data belonging to the UE in the common channel according to the ID.
If the network side sends the scheduling information to the UE by setting the dedicated channel, in step 302, the UE performs inverse operation on the data sent through the dedicated channel to obtain the data sent to the UE and obtain the scheduling information from the data. The UE specifically needs to perform descrambling, despreading, and demultiplexing on a radio signal transmitted through a dedicated channel, and perform inverse operation of multiplication on data transmitted on the set dedicated channel according to an orthogonal sequence to obtain the scheduling information.
The orthogonal sequence used by the UE may be sent to the UE by the network side, or may be obtained by other methods. For example, if each UE is assigned with an orthogonal sequence, the UE may directly obtain the orthogonal sequence from the present device.
If the network side sends the orthogonal sequence to the UE, and the network side directly sends the related information of the orthogonal sequence to the UE as described above, the UE may determine the corresponding orthogonal sequence according to the related information; if the network side firstly sends the sequence subset of the orthogonal sequence and sends the number of the orthogonal sequence to the UE when the UE transmits high-speed data, the UE directly determines the corresponding orthogonal sequence from the received orthogonal sequence subset after obtaining the number.
The UE in the above embodiment parses the scheduling information sent by the network side from the received data, determines whether the UE can currently perform high-speed data transmission according to the scheduling information, and transmits the scheduling information according to the determination result, so that signals sent by the UE that needs to transmit high-speed data can be guaranteed to be substantially orthogonal in time, thereby minimizing signal interference between UEs, and further improving the receiving performance of the base station.
The embodiment of the invention also provides network side equipment for processing high-speed data transmission, wherein the network side equipment is used for configuring TDM scheduling for the UE and determining scheduling information for controlling the UE to transmit high-speed data according to the configuration. And is also used for setting a channel for transmitting the scheduling information and transmitting the scheduling information to the UE through the channel.
The network side device is specifically shown in fig. 4, and includes a scheduling information configuration module, a channel configuration module, and a sending module. Wherein,
the scheduling information configuration module is used for configuring TDM scheduling for the UE and determining corresponding scheduling information for controlling the UE to transmit high-speed data according to the configuration;
a channel configuration module, configured to set a channel for transmitting the scheduling information;
and the sending module is used for sending the scheduling information to the UE through the channel.
The scheduling information configuring module may specifically set a control command value for the UE according to the configured TDM scheduling. That is, the scheduling information set for the UE is a control command value.
The channel configuration module may specifically set a dedicated channel, or may set a common channel.
If the dedicated channel is set, the sending module needs to multiply the scheduling information by an orthogonal sequence configured for the UE, load the obtained data on the dedicated channel, combine, spread, and the like the data loaded on the dedicated channel and other dedicated channels to form a wireless signal, and send the wireless signal to the UE.
For the scheme of setting a dedicated channel to transmit scheduling information, in order to save orthogonal sequence resources as much as possible, an orthogonal sequence resource pool may also be set. Specifically, the network side device may further include an orthogonal sequence setting module, configured to set an orthogonal sequence resource pool, and the module is further configured to select an orthogonal sequence for the UE from the orthogonal sequence resource pool and send the orthogonal sequence to the sending module when it is determined that the UE transmits high-speed data. The orthogonal sequence setting module is further configured to send information about the orthogonal sequence selected for the UE to the UE through the sending module.
In addition, the orthogonal sequence setting module may also be configured to set an orthogonal sequence resource pool, select a sequence subset from the orthogonal sequence resource pool, and broadcast the sequence subset to the UE through the sending module; and is further configured to select an orthogonal sequence for the UE from the subset of sequences upon determining that the UE is transmitting high speed data, and send the number of the orthogonal sequence to the UE via the sending module using an order command of the HS-SCCH channel.
In the embodiment, the TDM scheduling is set for the UE, the corresponding scheduling information for controlling the UE to transmit the high-speed data is determined according to the setting, the channel for transmitting the scheduling information is set, and the scheduling information is sent to the UE through the set channel, so that the UE can send the high-speed data according to the scheduling information, and thus, signals sent by the UE needing to transmit the high-speed data can be guaranteed to be basically orthogonal in time, so that signal interference between the UEs is reduced to the minimum, and further, the receiving performance of the base station is improved.
In addition, the scheme of setting the orthogonal sequence resource pool in the embodiment of the invention can further save the orthogonal sequence resources and effectively avoid the problem of orthogonal resource waste.

Specifically, if the UE determines that the high-speed data can be transmitted within the time of K TTIs in the future according to the scheduling information, the UE transmits the high-speed data; if it is determined that the transmission of the high speed data should be stopped for K TTIs in the future, the high speed data is not performed, and if the high speed data is previously transmitted, the transmission of the high speed data is stopped.

Of course, if the UE is performing high speed data transmission, the transmission of the current high speed data is stopped.

correspondingly, the parsing module is configured to obtain data sent to the UE from data sent by the common channel, and obtain the scheduling information from the obtained data. As described above, specifically, the network side may send an identifier such as an ID of the UE and the data together, and the parsing module determines whether the data is data of the UE according to the identifier.
If the network side sends data including scheduling information through a set dedicated channel, the transceiver module receives a wireless signal including the scheduling information sent by the network side through the dedicated channel;
correspondingly, the analysis module is used for performing descrambling, despreading, de-combining and other processing on the wireless signal sent by the dedicated channel, and performing inverse operation of multiplication on the data transmitted on the set dedicated channel according to the orthogonal sequence to obtain corresponding scheduling information.
