Description

Refactoring processing method and device

technical field

The present invention relates to the communication field, in particular, to a reconstruction processing method and device.

Background technique

Wideband Code Division Multiple Access (WCDMA for short) is one of the third-generation mobile communication air interface standards. WCDMA belongs to spread spectrum communication, which adopts technologies such as two-way closed-loop power control, transmit and receive diversity, RAKE receive anti-multipath fading, convolution code and Turbo code channel codec, etc. The mobile communication channel is very different from the fixed communication channel. When the receiver moves, the electromagnetic wave received by the antenna can be transmitted by the transmitter antenna and arrive in a straight line, or it can arrive after delayed propagation through multiple paths such as reflection and diffraction. Therefore, the received signal exists A lot of multipath (finger) delays, and these multipath results interfere with each other, forming multipath fading of the wireless channel. At the WCDMA baseband receiver, using the correlation of the pilot PN code, the resolvable multipath components in the received signal are tracked and received separately, and the baseband signal is output and path combined. This method of receiving signals is called RAKE reception. . RAKE reception performs correlation demodulation for each multipath respectively. These demodulators for correlation demodulation are also called multipath receivers (RAKE fingers), and then combine the outputs of these multipath receivers and send them to channel decoding. device for subsequent processing. RAKE reception uses multipath components to increase the received transmission power equivalently to achieve the purpose of resisting multipath fading.

In the WCDMA receiving system of the related technology, the multipath offset information received by RAKE and the correct demodulated and decoded user symbols are used, combined with channel estimation, to reconstruct these multipath results and restore the propagation in the wireless channel. After that, the amplitude and phase information when it reaches the receiver. Then these reconstructed multipath data are aligned to the system timing of the original antenna data for accumulation, and finally subtracted from the original antenna data, so as to offset the known user multipath to unknown (not demodulated and decoded correctly) users , increase the probability of correct demodulation and decoding for the remaining unknown users, the above processing is called interference cancellation.

Fig. 1 is a schematic diagram of reconstructing the received signal in the DPCCH channel of each user in the related art. As shown in Fig. 1, the base station obtains the Demodulation decision information; then according to the pilot information in the DPCCH channel received by each user and the obtained demodulation decision information, reconstruct the received signal in the DPCCH channel of each user, and reconstruct the received signal based on the reconstructed signal The received user baseband data is processed in parallel interference cancellation. Figure 2 is a simplified schematic diagram of the reconstruction process according to the related technology shown in Figure 1. As shown in Figure 2, a set of reconstruction resources is dedicated to each user's DPCCH channel, and 512 sets of DPCCH channel reconstruction are required for 512 users. Reconfiguration resources; if each user supports more types of channels, more reconfiguration resources are required.

However, in the actual system work, in most cases, it is not always necessary to reconstruct and offset the full users, for example, (1) the system has few users or channel types; (2) when the user/channel When the mutual interference is strong, there are not many users or channels with correct demodulation and decoding; (3) Only the users/channels with correct demodulation and decoding can perform reconstruction interference cancellation. If all users/channels are demodulated and decoded correctly , there is no need to refactor the offset.

Therefore, there is a problem of serious waste of reconstruction resources in the related art.

Detailed ways

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

In this embodiment, a reconstruction processing method is provided. FIG. 3 is a flowchart of the reconstruction processing method according to an embodiment of the present invention. As shown in FIG. 3 , the process includes the following steps:

Step S302, determining the number of reconstruction resource sets required by the interference cancellation system according to the performance of the interference cancellation system;

Step S304: Reconfigure the reconfiguration tasks in the interference cancellation system in the manner of multi-user and multi-channel sharing or time-division multiplexing a set of reconfiguration resources.

Through the above steps, after the number of reconfiguration resource sets is determined, the reconfiguration task is reconfigured by using multi-user multi-channel sharing or time-division using a set of reconfiguration resources. For the set of reconstruction resources, since the number of reconstruction resource sets is determined according to the system performance, the allocation of reconstruction resources is realized on demand. In addition, since there is no need to design circuits for the reconstruction resources of each channel of each user, the circuit size of the chip is reduced. Therefore, it not only solves the problem of wasting reconfiguration resources in related technologies, but also achieves the effect of allocating reconfiguration resources on demand and reducing the chip circuit area.

Multiple processing methods can be used to reconfigure the reconfiguration tasks in the interference cancellation system by using multi-user and multi-channel sharing or time-division multiplexing a set of reconfiguration resources. For example, the reconfiguration tasks can be scheduled into task queues according to predetermined rules. ; It should be noted that the above predetermined rules may include at least one of the following: cell identification (cell ID), antenna identification (antenna ID), user identification (user ID), multipath energy identification (multipath energy ID), and then, According to the task queue, the reconstruction tasks in the interference cancellation system are reconstructed in the way of multi-user and multi-channel sharing or time-division multiplexing a set of reconstruction resources. The processing method of arranging task queues is not only not easy to be confused, but also can choose a more reasonable refactoring sequence according to different specific needs by comparing different queues arranged according to the above predetermined rules set differently. In addition, the method of using multiple users and multiple channels to share or time-division multiplex a set of reconstruction resources is relative to the various channels for each user used in related technologies. For example, the previous needs are based on The corresponding reconstruction resources assigned to each channel of each user perform parallel reconstruction processing on each channel of each user, while the method of sharing or time-division multiplexing a set of reconstruction resources with multiple users and channels is to use a set of reconstruction resources to Various channels of multiple users are reconstructed in the form of queues.

When determining the number of sets of reconstruction resources required by the interference cancellation system according to the performance of the interference cancellation system, the reconstruction resources required by the system can be determined according to the performance (including performance requirements) of the interference cancellation system under consideration, preferably Specifically, before determining the number of reconfiguration resources required by the interference cancellation system, a maximum required number of sets can be determined at the stage of evaluating the system architecture, and implemented according to the maximum required number of sets, and then dynamically selected according to the dynamic changes of the system, for example, dynamic Generate and dynamically release reconstruction resources for other logical purposes.

Determine the number of reconstruction resource sets required by the interference cancellation system according to the performance of the interference cancellation system, that is, the overall basis for determining the number of reconstruction resource sets is: the total system performance requirements and the processing capacity of a single set of reconstruction resources, for example, the system needs to process 200 For each user with 2 channels, a total of 400 channels need to be processed. Assuming that a single set of reconstruction resources can handle 500 channels, only one set of reconstruction resources is required; assuming that a single set of resources can handle 300 channels, two sets of reconstruction resources are required , as another example, considering that the control channel and data channel in the interference cancellation system have different traffic timing characteristics, so a set of reconstruction resources can be allocated for the control channel and data channel of the interference cancellation system respectively. One set of reconstruction resources is assigned to the control channels and data channels of 100 users, and another set of reconstruction resources is allocated to the control channels and data channels of the other 100 users; as long as the above general basis is followed, the method of determining the number of reconstruction resource sets can be There are many, and the specific implementation is not limited.

Before the reconstruction task in the interference cancellation system is reconstructed by using multi-user multi-channel sharing or time-division multiplexing a set of reconstruction resources, in order to obtain more real-time and accurate reconstruction task information, the interference cancellation system can also be based on The system dynamic parameters of the system are monitored in real time for the reconstruction task of the interference cancellation system. Wherein, the system dynamic parameters indicated above may include at least one of the following: the number of users accessing the system, the number of users/channels successfully demodulated and decoded, and system control scheduling information. The purpose of real-time monitoring is to obtain real-time reconfiguration tasks corresponding to users/channels/multipaths that need to be reconfigured in the system, that is, to accurately reconfigure tasks that need to be reconfigured through immediate response to the actual situation of the system.

In this embodiment, a reconstruction processing device is also provided, which is used to implement the above embodiments and preferred implementation modes, and what has been explained will not be repeated here. As used below, the term "module" may be a combination of software and/or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

Fig. 4 is a structural block diagram of a reconstruction processing device according to an embodiment of the present invention. As shown in Fig. 4, the device includes a determination module 42 and a reconstruction module 44, and the device will be described below.

The determination module 42 is used to determine the number of reconstruction resource sets required by the interference cancellation system according to the performance of the interference cancellation system; the reconstruction module 44 is connected to the above determination module 42, and is used to use multi-user multi-channel sharing or time division multiplexing. The way of reconfiguring resources reconfigures the reconfiguration tasks in the interference cancellation system.

Preferably, the determination module is further configured to determine to allocate a set of reconstruction resources for the control channel and the data channel of the interference cancellation system respectively according to the timing characteristics of the control channel and the data channel in the interference cancellation system.

FIG. 5 is a preferred structural block diagram of the reconstruction module 44 in the reconstruction processing device according to an embodiment of the present invention. As shown in FIG. 5 , the reconstruction module 44 includes a scheduling unit 52 and a reconstruction unit 54. The following reconstruction unit is described.

The scheduling unit 52 is used to schedule the reconstruction task into a task queue according to predetermined rules; the reconstruction unit 54 is connected to the above-mentioned scheduling unit 52, and is used to adopt multi-user multi-channel sharing or time-division multiplexing according to the above-mentioned task queue. Reconfigure the reconfiguration tasks in the above-mentioned interference cancellation system by reconfiguring resources.

Fig. 6 is a structural block diagram of a reconstruction processing device according to a preferred embodiment of the present invention. As shown in Fig. 6, in addition to all the modules shown in Fig. 4, the device also includes a monitoring module 62, the monitoring module 62 is as follows Be explained.

The monitoring module is used to monitor the interference cancellation system according to the system dynamic parameters of the interference cancellation system before reconstructing the reconstruction task in the interference cancellation system by using multi-user multi-channel sharing or time-division multiplexing a set of reconstruction resources. Refactor tasks for real-time monitoring.

Reconfiguration resource allocation is rarely involved in related technologies, but the reconstruction resources are set according to the maximum number of supported users, that is, if two channel reconfigurations for 512 users are to be supported, 512*2=1024 sets of the same The hardware reconfiguration resources; and, the reconfiguration involved also belongs to the completely parallel reconfiguration, for example, the patent No. WO2008098416A, and the patent No. CN201110000528.5. However, the reconstruction in the above-mentioned related technologies all causes a serious waste of reconstruction resources to a certain extent.

Aiming at the above-mentioned problems in related technologies, in the patent application "Method and Device for Multipath Alignment and Accumulation", the problems of alignment efficiency of reconstructed multipath data and conflicts between reading and writing of front and rear path accumulation RAMs are solved. One clock can Alignment accumulates a configurable correlation length, so reconstruction computations are much more efficient. Based on this patent, this embodiment provides a reconfiguration resource processing method, and optimizes the interference cancellation system for multiple channels (control channels such as DPCCH and HS-DPCCH; data channels such as EDCH), using multi-user, multiple channel The method of sharing/time-division multiplexing reconstruction resources meets the system performance requirements on the premise that the implementation cost is as small as possible. Among them, the reconstruction resource allocation adopts dynamic detection and real-time scheduling, so as to realize the maximum utilization of reconstruction resources.

Since the relevant patents do not solve the problems of alignment efficiency and cumulative conflicts, high resource sharing cannot be achieved; the above-mentioned embodiments and preferred implementation modes optimize the design of an interference cancellation system, and a set of multi-user and multiple channel sharing/time-division multiplexing ( or several sets) of reconstruction resources, according to the compromise between performance requirements and implementation costs, determine the required number of parallel reconstruction resource sets, dynamically detect and schedule reconstruction tasks in real time, and maximize the use of reconstruction resources (allocation on demand). When determining the multipath task to be reconfigured, the multipath task that really needs to be reconfigured can be determined according to the baseband processing situation and software configuration, and then the tasks are serially scheduled according to cell ID/antenna ID/user ID/path ID, etc. structural resources for calculations. The method of multiplexing one or several sets of reconfiguration resources by adopting the above-mentioned embodiments and preferred implementation manners can reduce the area of the chip circuit. In addition, resource utilization is close to optimization (allocation on demand), and power consumption is low.

In this embodiment, an implementation mode is provided to allow all users and various channels to time-division multiplex the same set of reconstruction resources. FIG. As shown in 7, combined with the processing steps of the related art in FIG. 2, the difference from the related art is that the baseband processing step for one channel of a user in the related art is replaced by the baseband processing of multiple channels for multiple users; the channel of each user is used The step of aligning and accumulating each path of reconstruction in a dedicated set of reconstruction resources is replaced by the step of aligning and accumulating each path of reconstruction by using multiple channels to share a set of reconstruction resources with multiple users.

Fig. 8 is a schematic diagram of the process flow of multi-channel reconstruction, alignment and accumulation steps in multi-user multi-channel interference cancellation process according to an embodiment of the present invention. As shown in Fig. 8, this embodiment uses N users, each user Taking various channels (DPCCH, HS-DPCCH) as an example, the steps of "aligning and accumulating multiple channel reconstruction paths" shown in Figure 8 will be described. Task real-time detection step, reconstruction task real-time scheduling step, and reconstruction calculation alignment and accumulation step, the module that performs the step of "various channel reconstruction and each path alignment and accumulation" is referred to as the accumulation module for short, and Fig. 9 is according to the embodiment of the present invention As shown in FIG. 9 , the structural block diagram of the accumulation module that performs the step of "aligning and accumulating various channels for reconstruction and accumulation" is described below. The accumulation module 92 includes a detection module 922 (functionally equivalent to the above-mentioned monitoring module 62) for performing real-time detection steps of reconstruction tasks, a scheduling module 924 for performing real-time scheduling of reconstruction tasks (functionally equivalent to the above-mentioned scheduling unit 52) and The accumulating sub-module 926 for performing the steps of reconstruction, calculation, alignment and accumulation, the accumulation module 92 will be described below in conjunction with the steps included in the above-mentioned step of "aligning and accumulating each path of reconstruction of multiple channels".

The detection module 922 (or "reconfiguration task real-time detection module") is used to detect the users/channels/multipaths that actually need to be reconfigured (according to the number of system access users, the number of successfully demodulated and decoded users/channels, Software control scheduling and other information) real-time dynamic monitoring;

Scheduling module 924, (or called "reconfiguration task real-time scheduling module"), this module is used to schedule the users/channels that need to be reconfigured, and form a task queue, according to the cell ID/antenna ID/user ID/multipath energy level Wait for dispatch to the subsequent "reconstruction calculation alignment accumulation module 926";

Accumulation sub-module 926, (or called "reconstruction calculation alignment accumulation module"), this module is used to perform reconstruction and accumulation calculation on the paths to be reconstructed. To determine the number of sets of parallel reconstruction resources required, for example, since the control channel and the data channel have different traffic timing characteristics, a set of reconstruction calculation alignment and accumulation units can be allocated respectively; in addition, the graph can be used in the alignment accumulation step The processing method shown in 10, FIG. 10 is a schematic diagram of the optimal processing of the alignment and accumulation step in the reconstruction processing method according to the embodiment of the present invention. As shown in FIG. 10, on the one hand, the input information bits are combined with the spreading factor spreading code Perform a spreading operation to obtain chips (wherein, the spreading factor spreading code is used to distinguish different channels of the same user), and perform a scrambling operation on the chips obtained after spreading and the input scrambling code to obtain the scrambled chips (wherein, the above scrambling code is used to distinguish different users of the same channel); on the other hand, after the channel estimate is rotated in combination with the phase offset and frequency offset, the channel estimate after frequency offset compensation is obtained, and the obtained frequency offset compensation The channel estimation combined with the multipath offset generates filter coefficients; the scrambled chips and the generated filter coefficients are filtered to obtain reconstructed multipath samples, and after the obtained reconstructed multipath samples are aligned and accumulated, the output is to be Offset data. The alignment and accumulation step can adopt the processing method of the patent application "Multipath Alignment and Accumulation Method and Device", that is, through this step, a clock can be aligned and accumulated with a configurable correlation length, which has the characteristics of strong processing capacity and high processing efficiency. It will not be repeated here, but it should be noted that as long as the processing method of alignment and accumulation has the characteristics of strong processing capability and high processing efficiency, it can be used to realize the embodiment of the present invention. Here, no one-by-one examples are given.

Finally, the reconstruction and accumulation results of the two channels of all users are obtained, and then the offset processing is performed according to the step "offsetting the reconstruction and accumulation results".

Using the interference cancellation system provided by the above embodiments and preferred implementations, it is possible to use one clock to cancel a reconstructed multipath with a configurable correlation length, and to share/time-division multiplex a set of reconstructed resources with multiple users and channels (according to Compromise between performance requirements and implementation costs, determine the number of parallel reconstruction resource sets required by the system), real-time dynamic detection, scheduling reconstruction tasks, and maximize the use of reconstruction resources, so that the chip realizes small circuit area and low power consumption.
