Detailed Description

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort. For simplicity of the drawing, only the parts relevant to the present invention are schematically shown in each drawing, and they do not represent the actual structure thereof as a product.

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the invention. As shown in fig. 1, the communication system includes AN Access Network (AN) 110 and a Core Network (CN) 120, and a User Equipment (UE) 130 accesses a wireless Network through the AN 110 and communicates with other networks, such as a Data Network (Data Network), through the CN 120.

The AN may also be referred to as a radio access network (Radio Access Network, RAN), and AN apparatus on the AN side may be referred to as AN apparatus or a RAN apparatus, and may also be referred to as a base station. The names thereof are different in different communication schemes, and may be referred to as an evolved Node B (eNB) in a long term evolution (Long Term Evolution, LTE) system, and a next generation Node B (gNB) in a 5G system, for example. The AN device may also be a Centralized Unit (CU), a Distributed Unit (DU), or include a CU and a DU.

In order to improve the communication efficiency of UEs, wireless communication technologies are evolving continuously, and have evolved from the original 2G technology to the 5G technology. In the process of technical evolution, a scene of coexistence of new and old technologies often exists in the existing network, and in order to simultaneously support a plurality of wireless communication systems, wireless communication devices often have multiple modes. At present, for each wireless communication system, corresponding hardware modules are respectively developed, so that the hardware resource cost is very high.

For example, a receiver is provided at a receiving end of communication (UE side in downlink communication and AN side in uplink communication), and for example, a multimode receiver is shown in fig. 2, which is a schematic diagram of a conventional multimode receiver. As shown in fig. 2, the multimode receiver is provided with a demapping subsystem independently for each communication system, for example, a demapping subsystem 210 for the LTE system, a demapping subsystem 220 for the NR system, and a demapping subsystem 230 for the proprietary protocol system. Of course, a demapping subsystem for a 2G or 3G communication system may also be provided, which is not shown here for the sake of clarity. Only LTE, NR and proprietary protocols are described as examples.

Each demapping subsystem is provided with an independent hardware module, and each hardware module designs a demapping resource mapping sub-module of a channel and a signal supported by the communication system according to the communication system supported by the hardware module. For example, the demapping subsystem 210 supports the LTE system, and is provided with demapping sub-modules for various channels and signals in the LTE communication system, such as a primary synchronization Signal (Primary Synchronization Signal, PSS), a secondary synchronization Signal (Secondary Synchronization Signal, SSS), a channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS), a demodulation Reference Signal (Demodulation Reference Signal, DMRS), a sounding Reference Signal (Sounding Reference Signal, SRS), a physical broadcast channel (Physical Broadcast Channel, PBCH), a physical control format indicator channel (Physical Control Format Indicator Channel, PCFICH), a physical hybrid automatic repeat indicator channel (Physical Hybrid ARQ Indicator Channel, PHICH), a physical downlink control channel (Physical Downlink Control Channel, PDCCH), an enhanced physical downlink control channel (Enhanced Physical Downlink Control Channel, EPDCCH), a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), a physical uplink control channel (Physical Uplink Control Channel, PUCCH), and a physical random access channel (Physical Random Access Channel, PRACH). The demapping subsystem 220 supports an NR format, and is provided with demapping sub-modules of various channels and signals in the NR communication format, for example, a primary synchronization Signal (Primary Synchronization Signal, PSS), a secondary synchronization Signal (Secondary Synchronization Signal, SSS), a channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS), a demodulation Reference Signal (Demodulation Reference Signal, DMRS), a phase tracking Reference Signal (Phase Tracking Reference Signal, PTRS), a sounding Reference Signal (Sounding Reference Signal, SRS), a physical broadcast channel (Physical Broadcast Channel, PBCH), a physical downlink control channel (Physical Downlink Control Channel, PDCCH), a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), a physical uplink control channel (Physical Uplink Control Channel, PUCCH), a physical random access channel (Physical Random Access Channel, PRACH), and the like.

Each demapping subsystem indicates the channel and/or signal that the corresponding hardware module needs to do demapping by means of software, and correspondingly, the hardware module calls the corresponding demapping sub-module according to the indication so as to realize demapping of different signals and channels. For example, the demapping subsystem 210 indicates, in a software manner, that the hardware module needs to demap the PDCCH, and then the hardware module of the demapping subsystem 210 invokes the demapping subsystem of the PDCCH to implement the demapping of the PDCCH to obtain the information on the PDCCH.

The channels and/or signals supported by different communication schemes may be different, and the channels and/or signals may follow different manners in resource mapping, so that the demapping subsystem of each communication scheme is independently designed in the prior art. And for the proprietary wireless communication protocol, the customization of the demapping subsystem is also performed according to the proprietary protocol.

As can be seen, in the existing wireless communication apparatus, the demapping subsystem is developed for different wireless communication systems, respectively, resulting in very large hardware overhead; further, if custom requirements of the proprietary wireless communication protocol are to be supported, further hardware overhead is required. Similarly, for a multimode transmitter at the transmitting end (the AN side may be used for downlink communication and the UE side may be used for uplink communication), the same problem is faced in independently developing the resource mapping subsystem for each communication system.

In view of the above problems, the embodiments of the present invention control resource mapping or de-resource mapping of different communication systems by using a general control manner, so that different communication systems can perform resource mapping or de-resource mapping based on the general control manner, and when performing circuit design of resource mapping and de-resource mapping, there is no need to distinguish communication systems for design, thereby saving hardware resources. In addition, the problem of interference among different communication systems is considered, the extraction of interfered data is further reduced through a general control mode, the influence caused by interference is reduced, and the communication quality is improved.

Fig. 3 is a schematic diagram of a control method for mapping de-resources according to an embodiment of the present invention. The method is executed by a receiving end and is used for controlling the de-resource mapping of the receiving end to realize the receiving of the channel and/or the signal, as shown in fig. 3, and the method comprises the following steps:

s310: determining a channel and/or a signal to be received;

s320: determining a resource mapping position of a channel and/or a signal to be received in an effective bandwidth and an ineffective position in the resource mapping position, wherein the effective bandwidth comprises a plurality of resource units, each resource unit corresponds to one time domain resource unit and one frequency domain resource unit, and the channel and/or the signal to be received is mapped on part of resource units in the plurality of resource units in the effective bandwidth;

S330: generating configuration parameters according to the resource mapping positions and invalid positions in the resource mapping positions, wherein the configuration parameters comprise first parameters and second parameters, the first parameters are used for enabling data extraction at the resource mapping positions, and the second parameters are used for enabling data deduction at the invalid positions;

s340: the configuration parameters are used to control the de-resource mapping.

Correspondingly, the embodiment of the invention also provides a control method of the resource mapping, which is executed by the transmitting end and is used for controlling the resource mapping of the transmitting end to realize the transmission of the channel and/or the signal. Referring to fig. 4, the method includes the following steps:

s410: determining a channel and/or a signal to be transmitted;

s420: determining a resource mapping position of a channel and/or a signal to be transmitted in an effective bandwidth and an ineffective position in the resource mapping position, wherein the effective bandwidth comprises a plurality of resource units, each resource unit corresponds to one time domain resource unit and one frequency domain resource unit, and the channel and/or the signal to be transmitted is to be mapped on part of resource units in the plurality of resource units;

s430: generating configuration parameters according to the resource mapping positions and invalid positions in the resource mapping positions, wherein the configuration parameters comprise first parameters and second parameters, the first parameters are used for enabling data mapping in the resource mapping positions, and the second parameters are used for disabling data mapping in the invalid positions;

S440: the resource mapping is controlled using the configuration parameters.

In the above method, the resource mapping position of the channel and/or signal in the effective bandwidth is determined by determining the channel and/or signal of the current communication (to be sent or to be received), and then the data extraction or mapping at the resource mapping position is enabled by using the first parameter, so that different communication modes can perform resource mapping and/or de-resource mapping based on the universal control mode, and therefore, when the circuit design of resource mapping and de-resource mapping is performed, the design of distinguishing the communication modes is not needed, and the hardware resource is saved.

Furthermore, considering interference between different communication schemes, for example, when NR and LTE coexist, transmission of LTE may interfere with data transmission on some resource units of NR. At this time, the method of deducting or disabling mapping by using the parameter enabled data can not change the design of the protocol for the resource mapping of each channel and signal, only the interfered resource unit is determined according to the interference condition in the actual communication, the extraction of the data on the resource unit is deducted, the extraction of the error data is reduced by means of de-resource mapping, and the communication quality is improved; or, the data mapping of the interfered resource position is enabled, the probability of data being sent by mistake is reduced, and the communication quality is improved.

The above method may be implemented by means of software, for example stored in a memory in the form of a program, which is called by a processor to implement the above method. The method is a control method for the de-resource mapping or the resource mapping, the entity realizing the method is a control unit, and the control unit can control the universal hardware circuit by the method to realize the de-resource mapping and/or the resource mapping.

Specifically, please refer to fig. 5, which is a schematic diagram of a communication device according to an embodiment of the present invention. The communication device comprises a control unit 510 and a general circuit 520, the control unit 510 being connected to the general circuit 520, which connection may be a signal connection, i.e. may interact with each other. When the communication device is located at the receiving end, the generic circuit 520 may be a demapping circuit for demapping resources under the control of the control unit 510. When the communication device is located at the transmitting end, the general circuit 520 may be a resource mapping circuit for performing resource mapping under the control of the control unit 510. The receiving end may also be a transmitting end, for example, the UE may be a transmitting end during uplink communication to transmit uplink data to the AN device, and may also be a receiving end during downlink communication to receive downlink data transmitted by the AN device; for another example, the AN device may be a receiving end to receive uplink data sent by the UE during uplink communication, or may be a transmitting end to send downlink data to the UE during downlink communication. Thus, the generic circuitry 520 may also include both resource mapping circuitry and de-resource mapping circuitry. The control unit 510 is configured to perform the method shown in fig. 3 and/or fig. 4 to control the generic circuit 520 to perform the de-resource mapping and/or the resource mapping. For example, the control unit 510 generates control signaling, where the control signaling is a general configuration parameter, and the general configuration parameter refers to that the configuration parameter is applicable to each communication system, and may be used to control the de-resource mapping and/or the resource mapping of each communication system.

In the above step S310, the receiving end may determine a channel and/or a signal to be received according to the current communication system and the current communication state, where the channel and/or the signal to be received is the channel and/or the signal to be mapped by the resources to be de-mapped. The communication state is that the receiving end is in, for example, when the receiving end is UE, the UE is started and is in a state of needing cell search; or the UE requests uplink resources from the AN device in a state of detecting the PDCCH to acquire uplink grant. For another example, the receiving end is AN apparatus, and the AN apparatus schedules the UE to perform uplink transmission, and is in a state of receiving uplink data from the PUSCH. For example, after the UE is powered on, a cell search is required, at which point the UE detects PSS and SSS to determine the cell identity. When the UE works in an LTE mode, a receiving end determines that a signal to be received comprises PSS and SSS; or when the UE operates in the NR mode, the receiving end determines that the signal to be received includes PSS, SSS, and PBCH. For another example, the UE needs to detect the CSI-RS to perform channel measurement, and at this time, the receiving end determines that the signal to be received includes the CSI-RS. For another example, the UE detects the PDCCH to obtain uplink or downlink scheduling information, and further performs uplink transmission on a PUSCH resource indicated by the uplink scheduling information, or receives downlink data on a PDSCH resource indicated by the downlink scheduling information, where the receiving end determines that the channel to be received includes the PDCCH, and when performing downlink data reception, the channel to be received further includes the PDSCH.

Then, in the above step S320, the receiving end determines the resource mapping position of the channel and/or signal to be received within the effective bandwidth according to the channel and/or signal to be received. Each communication system agrees with the resource mapping positions of some channels or signals (for example, PSS, SSS, PBCH, PDCCH, etc.) through a protocol, for example, the resource mapping modes of some channels or signals are given in the protocol through formulas, tables, resource patterns (patterns), etc. The transmitting end follows the resource mapping mode when transmitting data, and correspondingly, the receiving end also follows the resource mapping mode when receiving data. In addition, for a channel in which the resource location may dynamically change, for example, PDSCH, the resource location of PDSCH is indicated by Downlink Control Information (DCI) on PDCCH, the UE may learn the resource location of PDSCH after acquiring the information on PDCCH. Therefore, after the receiving end determines the channel and/or signal to be received, the resource mapping position of the channel and/or signal to be received in the effective bandwidth can be determined according to the rule of the protocol; and for dynamically scheduled channels and/or signals, the resource locations of the dynamically scheduled channels and/or signals may be determined further based on information obtained from other channels.

Further, the receiving end may determine an invalid position in the resource mapping positions. In one implementation, the receiving end receives indication information indicating the invalid position from the transmitting end, so that the receiving end can determine the invalid position according to the indication information. For example, when NR and LTE coexist, transmission of NR on certain resource locations may be interfered by LTE transmission. At this time, the AN device may send indication information to the UE, informing the UE which data in the resource locations are not suitable to be extracted, and at this time, the UE may deduct the data in the resource locations according to the indication information. The indication information may be higher layer signaling or physical layer signaling. At this time, the receiving end is UE, and the transmitting end is AN apparatus. In another implementation, the receiving end may determine the invalid position according to interference between different communication schemes. For example, when the receiving end is AN apparatus, the AN apparatus may determine that some resource locations are interfered by the LTE communication system, so that transmission at these resource locations may be erroneous, and thus, the data extracted at these resource locations is subtracted.

The invalid positions indicated by the above indication information may be included in the determined resource mapping positions, or may be partially included in the resource mapping positions, and only the invalid positions included in the resource mapping positions are concerned for the channel and/or the signal to be received currently, so the invalid positions in the embodiment of the present application refer to the invalid positions included in the resource mapping positions, but the indication of other invalid positions by the indication information is not limited, and the control of other invalid positions by the second parameter is not limited.

Further, in the above step S330, a first parameter and a second parameter may be generated, the first parameter is used to enable data extraction at the resource mapping location, and the second parameter is used to enable data subtraction at the invalid location.

In connection with fig. 5 above, the control unit 510 may generate configuration parameters and input the configuration parameters to the demapping circuit 520. The demaresource mapping circuit 520 demaps the channel and/or the signal to be received according to the configuration parameters, and obtains information carried on the channel to be received and/or the signal to be received. For example, the receiving end is UE, the UE receives Downlink Control Information (DCI) from the AN device, the DCI is used to schedule PDSCH resources, the control unit 510 determines that a channel to be received is a PDSCH channel, and determines a resource mapping location of the PDSCH according to the DCI, so as to generate a first parameter that enables data extraction at the resource mapping location. In addition, the UE receives indication information from the AN device, the indication information indicating AN invalid position, and the UE generates a second parameter according to the indication information. The de-resource mapping circuit 520 extracts data at the resource mapping location according to the first parameter and subtracts the extracted data at the invalid location according to the second parameter to obtain data on the PDSCH. Alternatively, the demapping circuit 520 extracts data at the resource mapping position other than the invalid position according to the first parameter and the second parameter to acquire data on the PDSCH. Other channels and/or signals are similar and will not be described in detail herein.

The resource mapping and the de-resource mapping are inverse processes and similar to each other. For example, in step S410 above, the transmitting end may determine a channel and/or a signal to be transmitted according to the current communication system and the current communication state, where the channel and/or the signal to be transmitted is the channel and/or the signal to be mapped by the resource. The communication state is that the transmitting end is in, for example, when the transmitting end is UE, the UE transmits uplink data to the AN device by using PUSCH resources allocated by the AN device to the UE, at this time, a channel to be transmitted is PUSCH, and a resource location of the PUSCH is determined by the AN device and may be notified to the UE by the PDCCH, so that the UE transmits data by using PUSCH. For another example, the transmitting end is AN apparatus, the AN apparatus transmits uplink grant or downlink resource allocation to the UE through the PDCCH, and then the channel to be transmitted is a PDCCH channel, and the transmission of the PDCCH by the AN apparatus follows the provision of the protocol for the PDCCH search space; and the AN equipment sends a reference signal, such as a CSI-RS, to the UE so as to facilitate channel measurement by the UE, wherein the signal to be sent is the reference signal, and the sending of the CSI-RS conforms to the regulation of the resource position of the CSI-RS by the protocol. Then, in the above step S420, the transmitting end determines the resource mapping position of the channel and/or signal to be transmitted within the effective bandwidth according to the channel and/or signal to be transmitted, and further determines the invalid position in the resource mapping position, where the determination manner of the invalid position is the same as the above description. Further, in the above step S430, configuration parameters may be generated, and the configuration parameters may be used to control the mapping of data on the resource mapping locations. Reference may be made to the above description for details, and no further description is given.

Further, in the resource mapping process, in combination with fig. 5 above, the control unit 510 is configured to determine a channel and/or a signal to be transmitted in the current communication system, generate a configuration parameter, and input the configuration parameter to the resource mapping circuit 520, where the channel and/or the signal to be transmitted is the channel and/or the signal to be mapped. The resource mapping circuit 520 is configured to perform resource mapping on channels and/or signals to be transmitted according to the configuration parameters.

It can be seen that the above resource mapping circuit or resource mapping circuit 520 is a general module, and the control unit 510 does not need to identify different channels and signals in different communication schemes, but identifies the channels and/or signals to be mapped by the resources in different communication schemes, and provides configuration parameters to the resource mapping circuit or resource mapping circuit 520, and the resource mapping circuit or resource mapping circuit 520 performs resource mapping or resource mapping according to the configuration parameters. Therefore, the support of the de-resource mapping of various communication modes can be realized through a general hardware circuit, and a large amount of hardware cost is saved. In addition, with the evolution of technology and the requirements of private protocols, the design of the communication device is more beneficial to expanding new protocol requirements, and has better expandability compared with the prior art.

As described above, the control unit 510 may be implemented by means of software, i.e., the functions of the control unit 510 are stored in a memory through the formation of a program, which is called by a processor to implement the functions of the control unit 510. Therefore, when the subsequent evolution is carried out to support a new communication system or private protocol, the hardware structure can not be changed, and the updating software can complete the expansion, so that the hardware cost is further saved.

The above resource units are resource units in the effective bandwidth in the current communication system, and the receiving end can determine whether the channel and/or signal to be received is mapped on each resource unit according to the channel and/or signal to be received in the current communication system, so as to enable the de-resource mapping on the resource unit. The transmitting end can determine whether to map the channel and/or signal to be transmitted on each resource unit according to the channel and/or signal to be transmitted under the current communication system, so as to enable the resource mapping on the resource unit.

The effective Bandwidth may be a system Bandwidth, a carrier Bandwidth, or a current operating Bandwidth of the receiving end or the transmitting end, for example, a Bandwidth Part (BWP) in the NR system. The Resource unit may be one Resource Element (RE), and each Resource Element corresponds to one frequency domain Resource unit and one time domain Resource unit, where the frequency domain Resource unit may be a subcarrier, and the time domain Resource unit may be an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol. As technology evolves, the time domain resource units and the frequency domain resource units may change, but the application of the scheme in the new resource units is not changed.

Further, in order to facilitate the distinction of the roles of the first parameter and the second parameter by the general circuit, identification information may be provided, which is used for identifying data extraction or data subtraction. At this time, the first parameter includes first identification information and first location information, the first identification information is used for identifying data extraction, the first location information is used for indicating the above resource mapping location; the second parameter includes second identification information for identifying data subtraction and second location information for indicating the above invalid location.

The identification information and the location information may be configured independently or together. When the configuration is independent, the corresponding relation between the identification information and the position information can be established by using a preset rule, for example, the identification information and the position information are arranged in the same sequence. In the common configuration, the first location information and the first identification information of the first parameter may be configured to the general circuit 520 together, and the second location information and the second identification information of the second parameter may be configured to the general circuit 520 together, so that the general circuit 520 knows the correspondence between the location information and the identification information. The identification information may be implemented by an identification field (flag), which may include 1 bit, and when flag=0, represents extraction; when flag=1, deduction is indicated. Conversely, extraction may be indicated when flag=1, and subtraction may be indicated when flag=0.

Several implementations of the above first location information and second location information are described below using a de-resource map as an example.

In one implementation, the first location information for the first parameter may be generated by: setting a corresponding bit for each resource unit in the effective bandwidth; and setting the value of the bit corresponding to the resource unit mapped by the channel and/or the signal to be received as a first value, and setting the value of other bits as a second value to obtain the first position information. Similarly, for each resource unit in the effective bandwidth or resource mapping location, a corresponding bit is set; and setting the value of the bit corresponding to the invalid position as a first value, and setting the value of the other bits as a second value to obtain second position information. Wherein the second location information is generated only for resource units within the resource mapping location, the length of the second location information may be reduced, thereby reducing the parameters transferred between the control unit 510 and the de-resource mapping circuit 520.

At this time, the first location information includes a plurality of bits, each bit corresponds to a resource unit in the effective bandwidth, and the value of each bit is used to indicate whether to perform the operation identified by the first identification information on the data on the corresponding resource unit; and the second position information of the second parameter comprises a plurality of bits, each bit corresponds to one resource unit in the effective bandwidth or the resource mapping position, and the value of each bit is used for indicating whether to perform the operation identified by the second identification information on the data on the corresponding resource unit. The first value may be "1" and the second value may be "0". The reverse is also possible, i.e. the first value may be "0" and the second value may be "1".

For example, each RE in the effective bandwidth may be configured for each time domain resource unit, to obtain a bit map corresponding to the time domain resource unit, where each bit of the bit map corresponds to one RE in the time domain resource unit. For the first resource position information of the first parameter, if the data on the RE needs to be extracted through the resource de-mapping, setting the corresponding bit to be 1, otherwise setting the bit to be 0; for the second resource location information of the second parameter, if the data on the RE needs to be subtracted by the de-resource mapping, the corresponding bit is set to 1, otherwise, 0 is set. For another example, each RE in the effective time domain resource unit may be configured for each frequency domain resource unit, to obtain a bit map corresponding to the frequency domain resource unit, where each bit of the bit map corresponds to one RE in the frequency domain resource unit. For the first resource position information of the first parameter, if the data on the RE needs to be extracted through the resource de-mapping, setting the corresponding bit to be 1, otherwise setting the bit to be 0; for the second resource location information of the second parameter, if the data on the RE needs to be subtracted by the de-resource mapping, the corresponding bit is set to 1, otherwise, 0 is set.

The following description is made with reference to the accompanying drawings.

Please refer to fig. 6, which is a schematic diagram of a resource according to an embodiment of the present invention. As shown in fig. 6, the abscissa represents the time domain t and the ordinate represents the frequency domain f. Each small lattice represents one RE, one OFDM symbol for the time domain and one subcarrier for the frequency domain. An OFDM symbol in one slot (slot) and one Resource Block (RB) consisting of 12 subcarriers in the frequency domain, the RB may also be referred to as a Physical Resource Block (PRB). For example, in the LTE communication system, one slot includes 7 OFDM symbols under a normal Cyclic Prefix (CP), and one slot includes 6 OFDM symbols under an extended CP, and one RB pair includes 14 OFDM symbols or 12 OFDM symbols. For another example, in the NR communication system, one RB corresponds to one slot, and conventional CUnder P, one slot includes 14 OFDM symbols, and under extended CP, one slot includes 12 OFDM symbols. Fig. 6 is an example of 14 OFDM symbols in the time domain, which includes R ₀ The small boxes of (a) represent the boxes on which data is mapped, and the small boxes to be diagonal filled represent invalid positions.

For simplicity, it is assumed that the effective bandwidth corresponds to two RBs (or one RB pair) on the frequency domain, where each RB corresponds to 12 subcarriers for one OFDM symbol. And respectively configuring each RE in the effective bandwidth for each OFDM symbol index S in the effective bandwidth, so that the length of the effective bandwidth is W (S), and obtaining first position information and second position information, wherein the first position information and the second position information are bit maps (bitmaps) with the length of W (S). For the bit map of the first location information, if the data on the RE needs to be extracted through the de-resource mapping, the corresponding bit is set to 1, otherwise, set to 0. Taking the bitmap of the RE corresponding to the OFDM symbol index S being "0" as an example, the obtained bitmap is: [0 0 10 0 10 0 10 0 10 0 10 0 10 0 10 0 1], wherein the RE indexes decrease sequentially from left to right on the bitmap, the data on the 1 st, 4 th, 7 th, 10 th, 13 th, 16 th, 19 th and 22 nd RE are to be extracted. For the bit map of the second location information, if the data on the RE needs to be subtracted by means of the de-resource mapping, the corresponding bit is set to 1, otherwise, 0 is set. Taking the bitmap of the RE corresponding to the OFDM symbol index S being "0" as an example, the obtained bitmap is: [0 0 0 0 0 0 0 0 0 0 1 10 0 0 0 0 0 0 0 0 0 1 1], wherein the bitmap is left to right, the RE indices decrease in sequence, and the data on the 1 st, 2 nd, 13 th and 14 th RE are to be subtracted.

It can be seen that the above configuration parameters are implemented in a bit map (bitmap). That is, the configuration parameter includes a plurality of bits, each bit corresponds to one resource unit within the effective bandwidth, and the value of each bit is used to indicate whether to perform the operation identified by the identification information on the corresponding resource unit.

The position information of the above configuration parameter configures bits for each resource unit, and thus the overhead of the configuration parameter is relatively large, resulting in too large an amount of parameters being transferred between the control unit 510 and the general-purpose circuit 520.

Considering the problem of efficiency of parameter transfer between the control unit 510 and the general circuit 520, in another implementation, the effective bandwidth is divided into a plurality of resource unit groups, and a field is set for each resource unit group, where a value of the field is used to indicate whether the corresponding resource unit group is an effective resource unit group, and the effective resource unit group is a resource unit group including at least one effective resource unit, and the resource unit group excluding any effective resource unit is an ineffective resource unit group. In this way, a first location field indicating whether each resource unit group is an effective resource unit group is generated, a second location field is not set for an ineffective resource unit group, and a second location field is set for an effective resource unit group. The second location area is set as follows: setting a bit for each resource unit in the effective resource unit group, setting the value of the bit corresponding to the effective resource unit as a first value, setting other resource units as a second value, and obtaining a second position domain, wherein the effective resource unit is a resource unit mapped by a channel and/or a signal to be received.

Alternatively, the second parameter may share the first location field with the first parameter, or have the same first location field as the first parameter, and the description of the first location field is the same as the description of the first location field of the first parameter above. And a second location field is set for the set of active resource units. The second location field is set in the following manner: setting a bit for each resource unit in the effective resource unit group, setting the value of the bit corresponding to the invalid position as a first value, setting other resource units as a second value, and obtaining a second position domain, wherein the meaning of effective resources in the effective resource unit group is unchanged at this time, and the effective resources are resource units mapped by channels and/or signals to be received.

In the above implementation, for invalid resource unit groups, specific location fields may not be regenerated, and the amount of parameters transferred may be reduced. In addition, the parameter transfer amount is further reduced for the case where the first parameter and the second parameter share the first position field or the same position field is adopted.

Because the pattern of the resource mapping defined by the wireless communication protocol has strong regularity, the parameter transfer between the control unit 510 and the general circuit 520 can be greatly reduced by adopting the above manner, so that the processing efficiency of the whole de-resource mapping or resource mapping is improved.

The field in the above first location information may include one bit or may include a plurality of bits.

The resource unit groups can be divided for each frequency domain resource unit respectively, namely, each resource unit group corresponds to one frequency domain resource unit and a continuous A time domain resource units; or may be divided for each time domain resource unit, i.e. each resource unit group corresponds to one time domain resource unit and consecutive B frequency domain resource units; or dividing the time domain and the frequency domain simultaneously, namely, each resource unit group corresponds to A time domain resource units and B continuous frequency domain resource units. Wherein A and B are positive integers greater than 1, and can be specifically set according to the needs. For example, A may be any one of 3 to 14, or may be an integer multiple of 6 or 7; for example B may be an integer multiple of 6.

Please refer to fig. 7, which is a schematic diagram of another resource according to an embodiment of the present invention. As shown in fig. 7, the abscissa, the ordinate, and the meaning of each small lattice are the same as those of fig. 6, and will not be described again. Here, division into time domain resource units is taken as an example. As shown in fig. 7, the resource unit group is an RE group, the time domain resource unit is an OFDM symbol, and the frequency domain resource unit is a subcarrier. For each OFDM symbol S, the RE groups are divided by consecutive B (S) subcarriers as granularity, and one RE group includes consecutive B (S) REs, corresponding to one OFDM symbol S and consecutive B (S) subcarriers. Take OFDM symbol s=0, b (0) =6 as an example. Each RE group within the effective bandwidth (length W (S)), unit RE, is represented by 1 bit, resulting in a field map of length M (S), which is a bit map. If the RE group is valid, then the bit position 1 corresponding to the RE group is set to 0 otherwise. If the effective bandwidth is 100 RBs, where each RB corresponds to 12 REs, then M (0) =200 corresponding to the OFDM symbol index 0, and the domain map with length M (0) is: [1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1] wherein the right side of the domain map corresponds to a lower RE group index, which may be the lowest subcarrier index, the highest subcarrier index, or any one of the subcarrier indexes set in the RE group.

Further, for the set of REs indicated as valid in the domain map, each RE in the set of REs corresponds to a bit. For the second location field of the first parameter, if a certain RE is an RE in the resource mapping location, then the corresponding bit location 1, otherwise, set to 0, then a bit bitmap with length B (S) is obtained, as shown in fig. 7, for OFDM symbol 0, the bit bitmap with length B (0) is: [0 0 1 0 0 1]. For the third location field of the second parameter, if a certain RE is an RE in the invalid location, then the corresponding bit location 1, otherwise, set to 0, then a bit bitmap with length B (S) is obtained, as shown in fig. 7, for OFDM symbol 0, the bit bitmap with length B (0) is: [0 0 0 0 11 ] wherein a third location field may not be generated for RE groups having no invalid locations, e.g., for RE groups corresponding to OFDM symbol 0 and subcarrier indexes 6 to 11, so that the transfer parameters may be further saved. The right side of the above bitmap corresponds to the lower subcarrier index.

The valid REs refer to REs on which data is to be mapped or mapped, and the invalid REs refer to REs on which data is not mapped or to which data is not mapped. The valid RE group refers to an RE group including at least one valid RE, and the invalid RE group refers to an RE group not including any valid RE. The data may include information on a channel to be received or to be transmitted and/or a signal to be received or to be transmitted. Here, the valid RE group and valid RE are indicated by the bit value of "1", and the invalid RE group and invalid RE are indicated by the bit value of "0", which is not a limitation of the present invention.

In the above domain diagrams and bit maps, the lower index is taken as an example, and in other implementations, the higher index may be corresponding to the right, that is, the lower index may be corresponding to the left, which is not limited by the present invention.

The configuration parameters controlling the resource mapping are similar to the configuration parameters controlling the de-resource mapping, including the first parameter and the second parameter. The first parameter comprises first identification information and first position information, wherein the first identification information is used for identifying data mapping, and the first position information is used for indicating a resource mapping position; the second parameter includes second identification information for identifying disabling the data mapping and second location information for indicating an invalid location. The implementation of the first location information and the second location information is similar to the above, and will not be described again.

The resource mapping and the de-resource mapping are the inverse process, so the configuration parameter generation for controlling the resource mapping is the same as the above description and will not be repeated here.

Thus, by disabling the data mapping of the interfered location, the possibility of transmission errors caused by interference of the data can be reduced, thereby improving the communication quality.

The above configuration parameters are generated by the control unit 510 and configured to the general circuit, and the control unit 510 further provides the resource mapping to be decoded or the data storage information of the resource mapping to the general circuit 520, so that the general circuit 520 performs the resource mapping or the resource mapping based on the configuration parameters and the data storage information provided by the control unit 510.

For example, in the process of configuring the data storage information of the to-be-demapped resource, the information received by the radio frequency device is stored as an input of the demapping circuit 520, where the configuration parameter is used as a parameter input, and the data storage information of the to-be-demapped resource is used as a data input. The parameters are parsed by the de-resource mapping circuit 520 to extract data according to the data storage information.

The structure of the above general-purpose circuit 520 and the operations performed are further described below. Please refer to fig. 8, which is a schematic diagram of a general circuit 520 according to an embodiment of the present invention. As shown in fig. 8, the general circuit 520 includes a first storage element 521 and a second storage element 522 and an interface 523, wherein the interface 523 is configured to receive data storage information and configuration parameters from the control unit 510, and the first storage element 321 and the second storage element 322 are configured to buffer the data storage information and the configuration parameters, respectively. The general circuit 520 further includes a parameter analyzing circuit 524, and the parameter analyzing circuit 524 performs the operation shown in fig. 9 to acquire configuration parameters (S910); acquiring data storage information to be resource mapped/de-resource mapped (S920); data is mapped/extracted according to the configuration parameters (S930). Where "/" indicates that the demapping or resource mapping or both the demapping and the resource mapping can be performed. Optionally, the generic circuit 520 may further comprise a third storage element 525 for storing the result of the de-resource mapping. The first storage element 521, the second storage element 522, and the third storage element 525 may be implemented by the same memory or may be implemented by different memories, and the present invention is not limited thereto. The type of memory is not limited, and may be, for example, read Only Memory (ROM), random Access Memory (RAM), magnetic disk, or optical disk.

The resource mapping and the de-resource mapping are the inverse process, the mapping resources of each channel and/or signal under different communication systems follow the rules of respective communication protocols, and the description of the configuration parameters is the same as that in the de-resource mapping in the above embodiment.

The following describes the demapping process taking the demapping as an example.

Fig. 10 is a schematic diagram of a method for mapping a de-resources according to an embodiment of the present invention. As shown in fig. 10, the method is performed by the de-resource mapping circuit 520 of the receiving end, and includes the following steps:

s1010: acquiring configuration parameters, wherein the configuration parameters comprise a first parameter and a second parameter, the first parameter is used for enabling data extraction of a channel and/or a signal to be received at a resource mapping position within an effective bandwidth, and the second parameter is used for enabling data deduction at an invalid position in the resource mapping position;

s1020: acquiring data storage information of resource mapping to be decoded;

s1030: and acquiring data on the effective positions in the resource mapping positions from the data storage information to be subjected to resource mapping according to the first parameter and the second parameter, wherein the effective positions are the resource positions except for the ineffective positions in the resource mapping positions.

The content of the configuration parameters is the same as that described in the control method of the above de-resource mapping, and will not be described herein.

The parameter parsing circuit 524 may determine to extract data on the resource mapping location indicated by the first location information according to the first identification information of the first parameter; and determining the data deducting the invalid position indicated by the second position information according to the second identification information of the second parameter.

Then, in one implementation, the parameter resolution circuit 524 extracts the data at the resource mapping location indicated by the first location information, and subtracts the data at the invalid location indicated by the second location information from the extracted data. Alternatively, in another implementation, the parameter resolution circuit 524 determines data at a valid location in the resource mapping location based on the first location information and the second location information, and extracts the data at the valid location.

For example, the first location information for the first parameter/the second location information for the second parameter includes a plurality of bits, each bit corresponding to one resource unit within the effective bandwidth, and the value of each bit is used to indicate whether to perform the operation identified by the first identification information/the second identification information on the data on the corresponding resource unit. At this time, in the above step S1030, the parameter analyzing circuit 524 traverses each bit of the first position information and the second position information, extracts the data on the resource unit corresponding to the bit having the first value in the first position information, and skips the data extraction on the bit having the second value; and deducting the data on the resource unit corresponding to the bit with the first value in the second position information from the extracted data. Alternatively, the parameter analyzing circuit 524 traverses each bit of the first position information and the second position information, deducts the resource unit corresponding to the bit of the first value in the second position information from the resource unit corresponding to the bit of the first value in the first position information, and extracts the data on the remaining resource units.

For example, referring to fig. 6, for each OFDM symbol S of the effective bandwidth, the data storage information of the resource map to be de-mapped is processed according to the configuration parameters. Traversing the bitmap of the RE with the length W (S) when the first position information of the first parameter is the bitmap of the RE with the length W (S), extracting data of a corresponding position if the bit is 1, otherwise skipping; traversing the bitmap of the RE with the length W (S) when the second position information of the second parameter is the bitmap of the RE with the length W (S), deducting the data of the corresponding position if the bitmap is 1, and skipping if the bitmap is not 1; the final extracted data are data on the 4 th, 7 th, 10 th, 16 th, 19 th and 22 th REs and the resulting data include information on the channel to be received and/or the signal to be received.

In another implementation, the first location information of the first parameter and the second location information of the second parameter include a first location field, the first location field includes a plurality of fields, each field corresponds to one resource unit group, each resource unit group includes a plurality of resource units, and a value of each field is used to indicate whether the corresponding resource unit group is a valid resource unit group. For the valid resource unit group, the first location information further includes a second location field, where the second location field includes a plurality of bits, each bit corresponds to one resource unit in the valid resource unit group, and a value of each bit is used to indicate whether to perform an operation identified by the first identification information on data in the corresponding resource unit; and the second location information comprises a third location field, the third location field comprises a plurality of bits, each bit corresponds to one resource unit in the valid resource unit group, and the value of each bit is used for indicating whether to perform the operation identified by the second identification information on the data on the corresponding resource unit.

At this time, in the above step S1030, the parameter analyzing circuit 524 traverses each of the first location fields, determines the effective resource unit group, and skips the analysis of the ineffective resource unit group; for the effective resource unit group, extracting data on the effective resource unit according to the second position domain, and skipping data extraction on the ineffective resource unit; and deducting the data on the invalid position from the extracted data according to the third position field. Or deducting the resource unit corresponding to the bit with the first value in the third position domain from the resource unit corresponding to the bit with the first value in the second position domain, and extracting the data on the rest resource units.

For example, referring to fig. 7, for each OFDM symbol S of the effective bandwidth, RE groups are divided by granularity of consecutive B (S) subcarriers; then traversing the first location field, determining valid RE groups in the RE groups, and skipping processing of invalid RE groups. And for the effective RE group, determining effective RE in the effective RE group according to the second position domain, extracting data on the effective RE, and skipping data extraction on the ineffective RE. And deducting the data on the valid RE in the invalid position from the extracted data according to the third position field. Or deducting RE in the invalid position from the valid RE according to the second position domain and the third position domain, and extracting data on the rest RE.

In this way, the number of resource units or resource units that the demapping circuit 520 needs to parse is reduced, and the processing efficiency of the demapping circuit 520 is improved.

Correspondingly, the embodiment of the invention also provides a resource mapping method which is executed by the transmitting end and realizes the transmission of the channel and/or the signal. Referring to fig. 11, the method includes the steps of:

s1110: acquiring configuration parameters, wherein the configuration parameters comprise a first parameter and a second parameter, the first parameter is used for enabling data mapping of a channel and/or a signal to be transmitted at a resource mapping position in an effective bandwidth, and the second parameter is used for disabling data mapping at an invalid position in the resource mapping position;

s1020: acquiring data storage information of resource mapping;

s1030: and determining the effective position in the resource mapping position according to the first parameter and the second parameter, and mapping the data in the data storage information to be mapped to the effective position, wherein the effective position is the resource position except for the ineffective position in the resource mapping position.

In the above communication method and communication device, the data extraction at the resource mapping position is enabled by the parameters, in addition, the interference problem between different communication systems is considered, and the data deduction mode is enabled by the parameters, so that different communication systems can be subjected to the resource demapping based on the universal control mode, and the design of the communication systems is not needed to be distinguished when the circuit of the resource demapping is designed, so that the hardware resources are saved; in addition, the extraction of the interfered data can be reduced, the influence caused by interference is reduced, and the communication quality is improved through the subtraction of the parameter control data.

In addition, the resource mapping and the de-resource mapping are the inverse process, and can be performed in a similar way, so that the influence caused by interference is reduced, and the communication quality is improved.

The above receiving end may also be a transmitting end, and the transmitting end may also be a receiving end, for example, a UE serving as the transmitting end in uplink communication may be a receiving end in downlink communication; the receiving AN device in the downstream communication may be used as the transmitting end in the upstream communication. Thus, for the UE or the AN device, the above means for implementing resource mapping and the means for implementing resource demapping may be integrated together, the above communication method for controlling resource mapping or demapping is implemented by the same control unit, and the resource mapping circuit and the demapping circuit are implemented by the same or independent hardware circuits.

The foregoing is only a partial embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
