It may be stated that the features of the embodiments of the application may be combined with each other without conflict.
In the fourth generation communication system LTE (Long Term Evolution ) and the fifth generation communication system NR (New Radio), the control information of the downlink transmission is transmitted through a control channel.
In the LTE communication system, the smallest physical allocation unit of the control channel is a Resource Element group (Resource Element Group, REG), and each REG includes 4 Resource Elements (REs) that can carry transmission data. Its transmission data is carried in one or more consecutive control channel elements (Control Channel Element, CCEs), as shown in fig. 1, in an LTE communication system, for PDCCH (Physical Downlink Control Channel ), each CCE contains 9 REGs; these data will be mapped as uniformly as possible in REGs within the entire control channel bandwidth by interleaving of REGs.
In the NR communication system, data is similarly carried by CCE, but unlike in the LTE communication system, in PDCCH of NR, each CCE contains 6 REGs, and each REG includes 9 REs capable of controlling data transmission. Further, as shown in fig. 2, although the NR communication system performs interleaving (optional) processing of CCE-REGs within the corresponding CoreSet, actual data is not REG interleaved, but is directly mapped onto REGs of the corresponding CCEs in a manner of first subcarrier sequence and then symbol sequence.
In order to implement common mode reception of LTE channel data and NR channel data, during the reception of data, a reception process is generally performed on a symbol-by-symbol basis (i.e., each column of tables in fig. 1 and 2 corresponds to a single symbol). For NR channel data, such a manner is natural because the control channel data is mapped and transmitted according to symbol-by-symbol, but for LTE channel data, since the actual data is no longer carried in the order similar to the NR channel data, the inter-symbol REG deinterleaving process of the data needs to be additionally completed to restore the original order, which increases the implementation overhead.
Specifically, taking that each CCE of NR channel data includes 6 REGs, each REG is formed by 9 REs capable of transmitting information, a modulation mode of each RE is QPSK as an example, and each CCE of NR includes 6×9×2=108 soft bit information. For an application scenario of the receiving end (taking 56 CCEs as an example of a maximum specification scenario on the UE side), the buffer size of the soft bit information is at least 108×56=6048 soft bit information, and the bit width of the soft bit information is 6 bits as an example, where the buffer size is about 6048×6= 36288 bits.
Taking a CCE of LTE channel data as an example, where the CCE is composed of 9 REGs, each REG is composed of 4 transmissible REs, and the modulation scheme of each RE is QPSK, each CCE of LTE channel data contains 9×4×2=72 soft bit information. For the application scenario of the receiving end (taking the maximum specification scenario of the UE side of 796 REGs as an example), the bit width of the soft bit information is also taken as 6 bits as an example, and the buffer 796×4×2×6= 38208 bits of the soft bit information. It can be seen that the lowest buffer sizes of LTE channel data and NR channel data are substantially identical. However, when receiving LTE channel data, since the soft information of LTE needs to be deinterleaved, two buffer areas with the same size are needed, which results in that the size requirement of the buffer area is doubled to 38208×2 bits, which greatly reduces the channel data transmission efficiency, and meanwhile, the requirement on the hardware index such as the size of the buffer area increases.
An embodiment of the present application provides a channel data receiving method, applied to a channel data receiving device, where the channel data receiving method is shown in fig. 3, and includes the following steps:
step S101: channel data is received.
Specifically, in this step, acquiring the received channel data is a process in which the receiving device acquires the channel data through an antenna, an interface, and the like.
Step S102: when the received channel data is the second class of control channel data, the received channel data is processed according to the processing sequence of the first class of control channel data to obtain second soft bit information and de-interleaving sequence information corresponding to the received channel data, and the second soft bit information is placed at a position indicated by the de-interleaving sequence information in the to-be-blind detection buffer.
In some embodiments of the present application, the received channel data may include one type of control channel data and two types of control channel data according to type division, and other types of channel data may be specifically set according to hardware configuration of the channel data receiving apparatus and reception requirements of the received channel data. In some embodiments of the present application, one type of control channel data may be, for example, control channel data in an NR system, and may include, in particular, PDCCH, and one type of control channel data may be, for example, control channel data in an LTE system, and may include, in particular, PCFICH, PHICH, and PDCCH.
Further, in different embodiments of the present application, after the received channel data is acquired, the type of the received channel data may be determined according to the data characteristics such as the corresponding frequency band of the received channel data, which may be specifically set according to practical applications.
In some embodiments of the present application, the one type of control channel data comprises a plurality of one type of resource unit groups, and the two type of control channel data comprises a plurality of two type of resource unit groups.
In this step, when the received channel data is the second class control channel data, the channel data receiving apparatus processes the plurality of second class resource unit groups in the second class control channel data in the processing order of the plurality of first class resource unit groups in the first class control channel data in response to the received channel data being the second class control channel data, thereby obtaining second soft bit information and de-interleaving order information included in the processing result of the second class resource unit groups. Taking one type of control channel data as NR control channel data and the second type of control channel data as LTE control channel data as an example, the processing sequence of the NR resource unit groups in the NR control channel data is to process according to the receiving sequence of the resource unit groups, and the NR resource unit groups in the NR control channel data are carried in OFDM symbols, so in some embodiments of the present application, the processing sequence includes the receiving sequence of the OFDM symbols, and for the same OFDM symbol, the receiving may be performed according to the subcarrier sequence, and then for the LTE control channel data of the second type of control channel data, the plurality of LTE resource unit groups included in the LTE control channel data are also processed according to the processing sequence of the NR resource unit groups in the NR control channel data, that is, according to the receiving sequence, to implement common mode reception.
In the prior art, because the processing flows of the first-class control channel data and the second-class control channel data are different, in order to realize common mode reception of the first-class control channel data and the second-class control channel data, the received second-class control channel data can be processed according to the processing sequence of the first-class control channel data to obtain corresponding second soft bit information and de-interleaving sequence information, wherein the de-interleaving sequence information is used for indicating the de-interleaving sequence of the second-class resource unit group corresponding to the second soft bit information, and indicating the position of the second soft bit information in the to-be-blindly detected buffer based on the de-interleaving sequence, so that the second soft bit information in the to-be-blindly detected buffer can be sequenced according to the de-interleaving sequence, thereby realizing unification of the sequencing of the first soft bit information and the second soft bit information in the same to-be-blindly detected buffer, and further processing the data in the same set of logic to-be-blindly detected buffer.
Taking one type of control channel data as NR control channel data and the second type of control channel data as LTE control channel data as an example, for the LTE control channel data, firstly performing de-interleaving treatment and de-modulation treatment on resource unit groups one by one according to a symbol receiving sequence to acquire de-interleaving sequence information and second soft bit information of each resource unit group, and then placing the second soft bit information at a position indicated by the de-interleaving sequence information in a to-be-blind detection buffer. The to-be-blind-detected buffer memory can be a soft information buffer memory space, wherein some data can be temporarily stored, and the stored data can be read by other processing units at the later stage.
For example, as shown in fig. 4, the two types of control channel data are PDCCHs of LTE, where numbers marked in brackets represent a receiving sequence, numbers marked on left sides of brackets represent a deinterleaving sequence, first, a 0 th REG on a first symbol is processed to obtain second soft bit information corresponding to the 0 th REG and a deinterleaving sequence (7), a combined bit stream obtained by combining a bit stream mapped by the deinterleaving sequence 7 and second soft information bits corresponding to the 0 th REG may be output, and a processing unit of a later stage, for example, a bit-level processing unit, may place the second soft bit information corresponding to the 0 th REG in a position indicated by the deinterleaving sequence 7 in a to-be-blind-detected buffer according to the read deinterleaving sequence 7 after receiving the combined bit stream. After the processing of the 0 th REG is completed, the REG marked as 1 in brackets is processed, the de-interleaving sequence is 1, a combined bit stream obtained by combining the bit stream mapped by the de-interleaving sequence 1 and the second soft bit information corresponding to the 1 st REG is output, the processing unit of the later stage places the second soft bit information corresponding to the 1 st REG at the position indicated by the de-interleaving sequence 1 in the to-be-blind detection buffer according to the read de-interleaving sequence 1, and the processing procedure of the following 2 nd, 3 rd and 4 th … … REGs is the same as the above, and specific reference can be made to the specific description.
Further, in some embodiments of the present application, the sum of the number of bits occupied by the second soft bit information and the de-interleaving order information is less than or equal to the number of bits occupied by the first soft bit information, which allows a margin to be simultaneously de-output the bit stream mapped in the de-interleaving order when the second soft bit information is output using the output bit stream having the same size as the first soft bit information corresponding to the first type of control channel data.
In the channel data receiving method provided by the embodiment of the application, when the received channel data is the second class control channel data, the received second class control channel data is processed according to the processing sequence of the first class control channel data, the second soft bit information and the de-interleaving sequence information corresponding to the received second class control channel data are obtained from the processing result, after the de-interleaving sequence information is obtained, the second soft bit information can be placed at the position indicated by the de-interleaving sequence information in the to-be-blind detection buffer, the received second class control channel data is processed according to the processing sequence of the first class control channel data, so that the common mode receiving of the first class control channel data and the second class control channel data is realized, and a set of hardware and a set of processing logic are shared, so that compared with the prior art, the cost is reduced, the receiving efficiency of the channel data is higher, and the data processing efficiency of the common mode receiving of the first class control channel data and the second class control channel data is improved.
A second embodiment of the present application provides a method for receiving channel data, as shown in FIG. 5, including the following steps:
step S201: channel data is received.
Step S202: when the received channel data is the second class of control channel data, the received channel data is processed according to the processing sequence of the first class of control channel data to obtain second soft bit information and de-interleaving sequence information corresponding to the received channel data, and the second soft bit information is placed at a position indicated by the de-interleaving sequence information in the to-be-blind detection buffer.
It should be understood that, in this embodiment, the steps S201 and S202 are substantially the same as the steps S101 and S102 in the first embodiment, and specific reference may be made to the specific description in the first embodiment, which is not repeated herein.
Step S203: when the received channel data is one type of control channel data, a plurality of one type of resource unit groups are processed according to a processing sequence, first soft bit information corresponding to the processed one type of resource unit groups is obtained, and the first soft bit information is placed in a to-be-blind detection buffer according to the processing sequence.
In some embodiments of the present application, in this step, when the received channel data is one type of control channel data, the receiving device may process each one type of resource unit group directly according to a processing sequence of one type of resource unit group in the one type of control channel data in response to the received channel data being one type of control channel data, so as to obtain first soft bit information included in a processing result of each one type of resource unit group.
In some embodiments of the present application, taking a type of control channel data as NR control channel data as an example, as shown in fig. 2, resource unit groups in the NR control channel data are directly mapped onto resource unit groups corresponding to CCEs in a manner of first subcarrier sequence and then symbol sequence, where each resource unit group may be sequentially processed directly according to a receiving sequence of each resource unit group in the NR control channel data, to obtain first soft bit information corresponding to each resource unit group. And then placing the first soft bit information in a to-be-blind test buffer according to the processing sequence.
In the embodiment of the present application, the size of the combined bit stream (which may be described in detail in the first embodiment, and will not be described in detail here) may be set so that soft bit information included in different types of received channel data may be completely received. In different embodiments of the present application, the size of the combined bit stream may be confirmed using different methods, for example, in some embodiments of the present application, the size may be confirmed by data such as the number of bits of the first soft bit information of the first type of control channel data, the number of bits of the second soft bit information of the second type of control channel data, the number of bits of the de-interleaving order information, and the like.
In some embodiments of the present application, determining the size of the combined bitstream according to the data such as the number of bits of the first soft bit information, the number of bits of the second soft bit information, the number of bits of the deinterleave order information, and the like may specifically be determining the size of the combined bitstream to be a larger one between the sum value of the number of bits of the first soft bit information and the number of bits of the second soft bit information and the number of bits of the deinterleave order information.
It should be understood that the foregoing is merely illustrative of a method for determining a size of a combined bitstream according to data such as the number of bits of the first soft bit information, the number of bits of the second soft bit information, the number of bits of the de-interleaving order information, and the like in some embodiments of the present application, and is not limiting.
In some embodiments of the present aspect, the sum of the number of bits occupied by the second soft bit information and the de-interleaving order information is less than or equal to the number of bits occupied by the first soft bit information, and the size of the combined bit stream may be set to the number of bits occupied by the first soft bit information.
In some embodiments of the present application, when a class of resource unit groups is processed, the granularity of a single processing may be the entire class of resource unit groups. Specifically, for a class of resource unit group including J classes of resource units, since the sum of the number of bits occupied by the second soft bit information and the de-interleaving sequence information is smaller than or equal to the number of bits occupied by the first soft bit information, at this time, for the first soft bit information and the second soft bit information with arbitrary bit widths, the sum of the number of bits occupied by the second soft bit information and the de-interleaving sequence information can be smaller than or equal to the number of bits occupied by the first soft bit information, at this time, all J classes of resource units can be directly processed to obtain first soft bit information corresponding to the J classes of resource units, and the first soft bit information corresponding to the J classes of resource units is placed in a to-be-blind detection buffer.
