[0018] Figure 1 A flowchart of a PDSCH signal processing method provided in one embodiment of the present application.
[0019] First, refer to Figure 1 , an embodiment of the present application provides a PDSCH signal processing method, including:
[0020] Step 100: Acquire system configuration parameters; wherein the system configuration parameters include: a mapping model at the resource block (RB) level of the user equipment (UE), a data modulation mode corresponding to the RB of the user equipment, a small cycle delay diversity (SCDD) parameter corresponding to the RB of the user equipment, and a filtering parameter corresponding to the RB of the user equipment; output the small cycle delay diversity parameter corresponding to the RB of the user equipment and the filtering parameter corresponding to the RB of the user equipment to the next level.
[0021] In some exemplary embodiments, the system configuration parameters further include: the number of user equipments and the priority of each user equipment.
[0022] In some exemplary embodiments, when the system configuration parameters also include: the number of user devices and the priority of each user device, the RB-level mapping model of the user device may refer to the RB-level mapping model of each user device, the data modulation mode corresponding to the RB of the user device may refer to the data modulation mode corresponding to the RB of each user device, the SCDD parameters corresponding to the RB of the user device may refer to the SCDD parameters corresponding to the RB of each user device, and the filtering parameters corresponding to the RB of the user device may refer to the filtering parameters corresponding to the RB of each user device.

[0033] In some exemplary embodiments, the RB-level mapping model of the user equipment means that data mapped to each RB index is RB data, that is, a preset processed PDSCH signal corresponding to an RB of the user equipment, as shown in Table 1.
[0034] In some exemplary embodiments, the preset processed PDSCH signal corresponding to one RB of the user equipment includes: preset processed PDSCH signals corresponding to 12 (resource elements, REs) of the user equipment.
[0035] Table 1
[0036]
[0037] After obtaining the system configuration parameters, the embodiment of the present application outputs part of the system configuration parameters to the next level, that is, the system configuration parameters are transmitted in parallel during the signal processing process, which greatly saves the number of cycles of subsequent data processing and reduces system delay.
[0038] Step 101 : Mapping a preset processed PDSCH signal corresponding to an input RB of the user equipment to a corresponding RB index according to a mapping model at the RB level of the user equipment.
[0039] In some exemplary embodiments, the preset processed PDSCH signal may be a channel-coded PDSCH signal.
[0040] In some exemplary embodiments, the pre-processed PDSCH signal may be a PDSCH signal after channel coding and rate matching.
[0041] In some exemplary embodiments, the pre-processed PDSCH signal may be a PDSCH signal that has been channel-coded and scrambled.
[0042] In some exemplary embodiments, mapping the preset processed PDSCH signal corresponding to the RB of the input user equipment to the corresponding RB index according to the RB-level mapping model of the user equipment includes: determining the currently processed user equipment according to the priority of the user equipment; and mapping the preset processed PDSCH signal corresponding to the RB of the currently processed user equipment to the corresponding RB index according to the RB-level mapping model of the currently processed user equipment.
[0043] In some exemplary embodiments, determining the currently processed user equipment according to the priority of the user equipment includes: determining the user equipment with the highest priority among the currently unprocessed user equipment as the currently processed user equipment according to the priority of the user equipment, in order from highest priority to lowest priority.
[0044] In some exemplary embodiments, after mapping the preset processed PDSCH signal corresponding to the input RB of the user equipment to the corresponding RB index, the mapping result may be stored.
[0045] In some exemplary embodiments, the mapping result may refer to a mapping relationship between a preset processed PDSCH signal corresponding to an RB of the user equipment and an RB index.
[0046] In some exemplary embodiments, a preset processed PDSCH signal corresponding to an RB of the user equipment may be mapped to a corresponding RB index, and then the mapping result corresponding to the RB index may be stored.
[0047] In this manner, after completing the mapping step for one RB index, the step of storing the mapping result corresponding to the RB index and the mapping step for subsequent RB indexes can be performed in parallel, thereby achieving pipeline data processing.
[0048] In some exemplary embodiments, after the preset processed PDSCH signals corresponding to all RBs of the user equipment are mapped to corresponding RB indexes, the mapping results corresponding to all RB indexes are stored.
[0049] Step 102: For the RB index corresponding to the non-empty RB, according to the data modulation mode corresponding to the RB of the user equipment, the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB is modulated to obtain the modulated data corresponding to the RB of the user equipment, and the modulated data corresponding to the RB of the user equipment is output to the next level.
[0050] In some exemplary embodiments, after obtaining the modulation data corresponding to the RB of the user equipment, the preset processed PDSCH signal of the RB index corresponding to the non-empty RB is replaced with the modulation data corresponding to the RB according to the RB-level mapping model. When the modulation data corresponding to the RB of the user equipment is output to the next level, the modulation data corresponding to the RB is read from the RB-level mapping model and output to the next level.
[0051] In some exemplary embodiments, the modulated data may be IQ data.
[0052] In some exemplary embodiments, modulation processing is performed on a unit basis using a pre-processed PDSCH signal mapped to one RB index. In other words, the pre-processed PDSCH signals of 12 REs contained in the pre-processed PDSCH signal mapped to one RB index are processed in parallel. This parallel processing approach improves processing speed.
[0053] In some exemplary embodiments, according to the data modulation mode corresponding to the RB of the user equipment, the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB is modulated to obtain the modulated data corresponding to the RB of the user equipment, including: according to the data modulation mode corresponding to the RB of the user equipment, the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB is modulated in units of the bit stream data of the resource unit of the RB of the user equipment to obtain the modulated data corresponding to the RB of the user equipment.
[0054] In the mapping-first-then-modulation method of the embodiment of the present application, since the preset processed PDSCH signal mapped to the RB index corresponding to the empty RB does not need to be modulated again, the data bandwidth in the calculation process is greatly reduced.
[0055] In the mapping-first-and-then-modulation method of the embodiment of the present application, since the maximum width of the unmodulated data is 10 bits (bit) and the minimum is 2 bits, calculated based on the maximum format of 10 bits, the space occupied by a single RB is 10×12=120 bits. Compared with the modulation-first-and-then-mapping method, in which the space occupied by each RB is 32×12=384 bits, the space occupied by a single RB in the mapping-first-and-then-modulation method is reduced by 264 bits, and the modulated data obtained after modulation does not need to be stored, which greatly reduces the storage space and saves chip area.
[0056] In some exemplary embodiments, after modulating the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB according to the data modulation mode corresponding to the RB of the user equipment to obtain the modulation data corresponding to the RB of the user equipment, the method also includes: receiving the SCDD parameters corresponding to the RB of the user equipment and the filtering parameters corresponding to the RB of the user equipment inputted from the previous level; outputting the filtering parameters corresponding to the RB of the user equipment to the next level; determining the multiplication factor corresponding to the RB of the user equipment according to the SCDD parameters corresponding to the RB of the user equipment; receiving the modulation data corresponding to the RB of the user equipment inputted from the previous level; determining the phase-rotated data corresponding to the RB of the user equipment according to the multiplication factor corresponding to the RB of the user equipment and the modulation data corresponding to the RB of the user equipment; outputting the phase-rotated data corresponding to the RB of the user equipment to the next level; receiving the filtering parameters corresponding to the RB of the user equipment inputted from the previous level; determining the filtering coefficient corresponding to the RB of the user equipment according to the filtering parameters corresponding to the RB of the user equipment; receiving the phase-rotated data corresponding to the RB of the user equipment inputted from the previous level; and performing frequency offset compensation on the phase-rotated data corresponding to the RB of the user equipment according to the filtering coefficient corresponding to the RB of the user equipment.
[0057] In the above exemplary embodiment, after receiving the modulation data corresponding to the RB of the user equipment input at the previous level, there is no need to store the modulation data. The phase-rotated data corresponding to the RB of the user equipment can be directly determined based on the multiplicative factor corresponding to the RB of the user equipment and the modulation data corresponding to the RB of the user equipment, thereby realizing a pipeline data processing process and greatly saving storage space.
[0058] In the above exemplary embodiment, after receiving the phase-rotated data corresponding to the RB of the user equipment input at the previous level, it is not necessary to store the phase-rotated data. The frequency offset compensation is performed directly on the phase-rotated data corresponding to the RB of the user equipment according to the filter coefficient corresponding to the RB of the user equipment, thereby realizing a pipeline data processing process and greatly saving storage space.
[0059] In some exemplary embodiments, the following steps are performed in parallel:
[0060] Output the small-cycle delay diversity parameter corresponding to the RB of the user equipment and the filtering parameter corresponding to the RB of the user equipment to the next level;
[0061] Mapping the preset processed PDSCH signal corresponding to the input RB of the user equipment to the corresponding RB index, and modulating the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB to obtain modulated data corresponding to the RB of the user equipment;
[0062] Receive the SCDD parameter corresponding to the RB of the user equipment and the filtering parameter corresponding to the RB of the user equipment inputted at the previous level; determine the multiplicative factor corresponding to the RB of the user equipment according to the small cycle delay diversity parameter corresponding to the RB of the user equipment;
[0063] Output the filtering parameters corresponding to the RB of the user equipment to the next level;
[0064] Receive the filtering parameters corresponding to the RB of the user equipment inputted at the previous level; and determine the filtering coefficient corresponding to the RB of the user equipment according to the filtering parameters corresponding to the RB of the user equipment.
[0065] In some exemplary embodiments, the preset processed PDSCH signals corresponding to all RBs of the input user equipment can be mapped to the corresponding RB index according to the RB-level mapping model of the user equipment, and then, for the RB index corresponding to the non-empty RB, the preset processed PDSCH signals mapped to the RB index corresponding to the non-empty RB can be modulated according to the data modulation method corresponding to the RB of the user equipment to obtain the modulated data corresponding to the RB of the user equipment.
[0066] In some exemplary embodiments, after obtaining the system configuration parameters, the step of outputting the SCDD parameters corresponding to the RB of the user equipment and the filtering parameters corresponding to the RB of the user equipment to the next level can be directly executed, without waiting for the modulation of the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB to obtain the modulated data corresponding to the RB of the user equipment before executing the step of outputting the SCDD parameters corresponding to the RB of the user equipment and the filtering parameters corresponding to the RB of the user equipment to the next level. In other words, after obtaining the system configuration parameters, the step of outputting the SCDD parameters corresponding to the RB of the user equipment and the filtering parameters corresponding to the RB of the user equipment to the next level can be performed in parallel with the steps of mapping the preset processed PDSCH signal corresponding to the RB of the user equipment to the corresponding RB index and modulating the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB to obtain the modulated data corresponding to the RB of the user equipment.
[0067] In some exemplary embodiments, after receiving the SCDD parameters and filtering parameters corresponding to the RBs of the user equipment inputted from the previous stage, the step of outputting the filtering parameters corresponding to the RBs of the user equipment to the next stage can be directly executed, without waiting for the determination of the phase-rotated data corresponding to the RBs of the user equipment based on the multiplicative factors and the modulation data corresponding to the RBs of the user equipment before executing the step of outputting the filtering parameters corresponding to the RBs of the user equipment to the next stage. In other words, after receiving the SCDD parameters and filtering parameters corresponding to the RBs of the user equipment inputted from the previous stage, the step of outputting the filtering parameters corresponding to the RBs of the user equipment to the next stage can be performed in parallel with the steps of mapping the input preset processed PDSCH signal corresponding to the RBs of the user equipment to the corresponding RB index, modulating the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB to obtain the modulation data corresponding to the RBs of the user equipment, and determining the multiplicative factor corresponding to the RBs of the user equipment based on the small-cycle delay diversity parameter corresponding to the RBs of the user equipment.
[0068] In some exemplary embodiments, after receiving the SCDD parameters corresponding to the RBs of the user equipment and the filtering parameters corresponding to the RBs of the user equipment from the previous level, the step of determining the multiplicative factor corresponding to the RBs of the user equipment based on the SCDD parameters corresponding to the RBs of the user equipment can be directly performed, without waiting for the modulation submodule 2014 to modulate the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB to obtain the modulated data corresponding to the RBs of the user equipment before performing the step of determining the multiplicative factor corresponding to the RBs of the user equipment based on the SCDD parameters corresponding to the RBs of the user equipment. In other words, after receiving the SCDD parameters corresponding to the RBs of the user equipment and the filtering parameters corresponding to the RBs of the user equipment from the previous level, the step of determining the multiplicative factor corresponding to the RBs of the user equipment based on the SCDD parameters corresponding to the RBs of the user equipment can be performed in parallel with the steps of mapping the preset processed PDSCH signal corresponding to the RBs of the user equipment to the corresponding RB index and modulating the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB to obtain the modulated data corresponding to the RBs of the user equipment.
[0069] In some exemplary embodiments, after receiving the filter parameters corresponding to the RBs of the user equipment inputted from the previous stage, the step of determining the filter coefficients corresponding to the RBs of the user equipment based on the filter parameters corresponding to the RBs of the user equipment can be directly performed, without waiting for the determination of the phase-rotated data corresponding to the RBs of the user equipment based on the multiplicative factors corresponding to the RBs of the user equipment and the modulation data corresponding to the RBs of the user equipment to be completed before performing the step of determining the filter coefficients corresponding to the RBs of the user equipment based on the filter parameters corresponding to the RBs of the user equipment. In other words, after receiving the filter parameters corresponding to the RBs of the user equipment inputted from the previous stage, the step of determining the filter coefficients corresponding to the RBs of the user equipment based on the filter parameters corresponding to the RBs of the user equipment can be performed in parallel with the steps of mapping the input preset processed PDSCH signal corresponding to the RBs of the user equipment to the corresponding RB index, modulating the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB to obtain the modulation data corresponding to the RBs of the user equipment, and determining the multiplicative factor corresponding to the RBs of the user equipment based on the small-cycle delay diversity parameter corresponding to the RBs of the user equipment.
[0070] In some exemplary embodiments, the preset processed PDSCH signal corresponding to an RB of an input user device can be mapped to the corresponding RB index according to the RB-level mapping model of the user device. If the RB index to which the preset processed PDSCH signal corresponding to the RB is mapped corresponds to a non-empty RB, the preset processed PDSCH signal corresponding to the RB is modulated according to the data modulation method corresponding to the RB of the user device to obtain the modulated data corresponding to the RB; if the RB index to which the preset processed PDSCH signal corresponding to the RB is mapped corresponds to an empty RB, the preset processed PDSCH signal corresponding to the RB is not modulated.
[0071] In this way, the mapping step and the modulation step can be performed in parallel. Specifically, after the step of mapping the preset processed PDSCH signal corresponding to the i-th RB to the corresponding RB index, the step of modulating the preset processed PDSCH signal corresponding to the i-th RB to obtain the modulated data corresponding to the i-th RB can be performed in parallel with the step of mapping the preset processed PDSCH signal corresponding to the RB after the i-th RB to the corresponding RB index.
[0072] In some exemplary embodiments, after modulating the preset processed PDSCH signal mapped to the RB index of all corresponding non-empty RBs, the modulated data corresponding to all RBs of the user equipment may be output to the next stage in units of the modulated data corresponding to the RBs.
[0073] In some exemplary embodiments, after modulating a preset processed PDSCH signal mapped to an RB index corresponding to a non-empty RB, the preset processed PDSCH signal of the RB index corresponding to the non-empty RB may be output to a next stage.
[0074] In this way, after the step of modulating the preset processed PDSCH signal mapped to an RB index corresponding to a non-empty RB, the step of outputting the preset processed PDSCH signal of the RB index corresponding to the non-empty RB to the next level can be performed in parallel with the step of modulating the preset processed PDSCH signal mapped to the RB index corresponding to the subsequent non-empty RB.
[0075] In some exemplary embodiments, determining the multiplicative factor corresponding to the RB of the user equipment based on the SCDD parameters corresponding to the RB of the user equipment includes: determining the form data corresponding to the RB of the user equipment based on the SCDD parameters corresponding to the RB of the user equipment; and determining the multiplicative factor of each resource unit corresponding to the RB of the user equipment based on the form data corresponding to the RB of the user equipment.
[0076] In some exemplary embodiments, after determining the multiplicative factor corresponding to the RB of the user equipment based on the SCDD parameters corresponding to the RB of the user equipment, and before determining the phase-rotated data corresponding to the RB of the user equipment based on the multiplicative factor corresponding to the RB of the user equipment and the modulation data corresponding to the RB of the user equipment, the method also includes: storing the multiplicative factor corresponding to the RB of the user equipment in a first-in-first-out cache; and reading the multiplicative factors corresponding to the RB of the user equipment from the first-in-first-out cache in sequence.
[0077] In some exemplary embodiments, frequency offset compensation is performed on phase-rotated data corresponding to the RB of the user equipment according to the filtering coefficient corresponding to the RB of the user equipment, including: filtering the phase-rotated data corresponding to the RB of the user equipment according to the filtering coefficient corresponding to the RB of the user equipment to obtain filtered data corresponding to the RB of the user equipment; and power factor compensation is performed on the filtered data corresponding to the RB of the user equipment to obtain compensated data corresponding to the RB of the user equipment.
[0078] The PDSCH signal processing method provided in the embodiment of the present application first maps the preset processed PDSCH signal corresponding to the RB of the user equipment to the corresponding RB index, and then modulates the preset processed PDSCH signal mapped to the RB index corresponding to the non-empty RB. Since the mapping-first-then-modulation method does not require modulation of the preset processed PDSCH signal mapped to the RB index corresponding to the empty RB, the data bandwidth in the calculation process is greatly reduced. Since the mapping-first-then-modulation method does not require storage of the modulated data, the storage space is reduced, thereby saving chip area and power consumption as a whole.
