Background
In a long term evolution (Long Term Evolution, LTE) system, a downlink channel adopts a multi-carrier orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) waveform, and an uplink channel adopts a single-carrier waveform, specifically, a discrete fourier transform Spread-spectrum orthogonal frequency division multiplexing (Discrete Fourier Transform-Spread-OFDM, DFT-S-OFDM). In a New Radio (NR) system, a downlink channel adopts an OFDM waveform, and an uplink channel adopts a mode that two waveforms are matched, wherein the two waveforms are respectively OFDM and DFT-S-OFDM. The uplink adopts single carrier DFT-S-OFDM, because the single carrier has lower peak average power ratio (Peak to Average Power Ratio, PAPR), and can transmit data with higher transmitting power, thereby effectively improving the uplink coverage performance of users.

Detailed Description
For a more complete understanding of the features and technical content of the embodiments of the present application, reference should be made to the following detailed description of the embodiments of the present application, taken in conjunction with the accompanying drawings, which are for purposes of illustration only and not intended to limit the embodiments of the present application.
The embodiment of the application provides a design method of a control resource set, which is applied to network equipment and used for indicating that the waveform of a control channel is a single carrier waveform. Fig. 1 is a first flow chart of a design method for controlling a resource set according to an embodiment of the present application, as shown in fig. 1, the method may specifically include:
step 101: configuring a control resource set to adopt single carrier wave waveform transmission; the control resource set comprises a first type symbol and a second type symbol, wherein the first type symbol is used for transmitting a reference signal, and the second type symbol is used for transmitting control information;
step 102: and sending the configuration information of the control resource set.
Here, the execution subject of steps 101 to 102 may be a processor of the network device. Here, the network device may be a fixed station or a base station for communicating with the terminal device, and specifically may be an access point, a Node B, a base station, an enhanced base station, an evolved Node B (eNB), or other names. The terminal device may be a user device having a wireless communication function. Such as smartphones, personal computers (e.g., tablet, desktop, notebook, netbook, palmtop, etc.), electronic book readers, portable multimedia players, audio/video players, cameras, virtual reality devices, wearable devices, etc.
In some embodiments, the configuration information of the control resource set includes waveform indication information; the waveform indication information is used for indicating the control resource set to adopt single carrier waveform transmission.
In practical application, the single carrier control resource set is not suitable for frequency domain multiplexing of the multi-carrier control resource set, and in addition, the single carrier control resource set mainly faces to coverage enhancement scenes and occupies more time-frequency resources. Therefore, consider that the single carrier control resource set occupies a larger frequency domain resource. For example, the NR system has a large Bandwidth and supports design of a Bandwidth part (BWP). Therefore, the control resource set can be implicitly indicated to adopt single carrier wave waveform transmission based on the bandwidth of the control resource set, so that signaling overhead is reduced, and the control channel waveform is not required to be indicated through additional signaling. Here, BWP refers to a portion of frequency domain resources within a carrier bandwidth allocated to a terminal by a base station. The BWP may have a size less than or equal to the maximum bandwidth supported by the terminal and may be a contiguous frequency domain resource, e.g., the BWP may include a contiguous plurality of subcarriers and the BWP may include a plurality of contiguous physical resource blocks (physical resource block, PRBs).
In practical application, the waveform indication information is bandwidth information of the control resource set, and when the bandwidth information is all bandwidths of the partial bandwidth BWP or preset frequency domain resources, the control resource set is implicitly indicated to adopt single carrier waveform transmission.
Specifically, when the number of the preset frequency domain resources is greater than a preset characteristic value, implicitly indicating that the control resource set is transmitted in a single carrier mode. For example, the control resource set includes a certain number of frequency domain resources, where the frequency domain resources may take RBs as units, and when the number of RBs of the frequency domain resources is greater than a preset characteristic value (for example, the preset characteristic value is 20 RBs), it is determined that the control resource set uses single carrier waveform transmission.
In some embodiments, the set of control resources includes one first type of symbol and at least one second type of symbol; wherein the first type of symbol is a first symbol in the control resource set, and the at least one second type of symbol is a symbol after the first symbol in the control resource set.
Fig. 2 is a schematic structural diagram of a control resource set in the prior art, where the current control resource set is configured with at most 3 OFDM symbols, and includes a certain number of CCEs. As shown in fig. 2, the control resource set is configured with 2 OFDM symbols in the time domain and occupies a part of the bandwidth in the frequency domain, and the control resource set includes k+1 CCEs, each CCE contains 6 REGs, and is mapped from the time domain to the frequency domain. Each REG occupies one RB in the frequency domain and one OFDM symbol in the time domain. Each REG includes 12 REs, 3 of which are used to transmit reference signals and the remaining 9 REs are used to transmit control information.
In the embodiment of the application, when the control resource set adopts single carrier wave waveform transmission, in order to ensure better single carrier wave coverage performance, the reference signal occupies an independent OFDM symbol, and the control information occupies other symbols.
Fig. 3 is a schematic diagram of a first composition structure of a control resource set in the embodiment of the present application, as shown in fig. 3, the control resource set occupies X symbols in a time domain and occupies the entire bandwidth in a frequency domain, a reference signal of a single carrier control resource set occupies a first symbol (i.e., a first type symbol) in the control resource set, and control information occupies one or more symbols (i.e., at least one second type symbol) after the first symbol. For example, when x=2, the first symbol in the control resource set is used for transmitting a demodulation reference signal (Demodulation Reference Signal, DMRS), and the second symbol is used for transmitting DCI. When x=3, the first symbol in the control resource set is used for transmitting DMRS, and the second and third symbols are used for transmitting DCI. When x=4, the first symbol in the control resource set is used for transmitting DMRS, and the second to fourth symbols are used for transmitting DCI.
Correspondingly, the method further comprises the steps of: radio resource control (Radio Resource Control, RRC) signaling controlling the set of resources is configured to indicate Quasi co-located (QCL) information for the first type of symbol and the second type of symbol.
Illustratively, the first type of symbol has the same QCL information as the second type of symbol, i.e., indicates that the control information and the reference signal are transmitted over the same beam.
In other embodiments, the set of control resources includes at least one symbol group; wherein each symbol group comprises a first type symbol and at least a second type symbol.
Fig. 4 is a schematic diagram of a second composition structure of a control resource set in the embodiment of the present application, where, as shown in fig. 4, the control resource set occupies X symbols in a time domain, occupies the entire bandwidth in a frequency domain, an even number of symbols are configured for a single carrier control resource set, each two symbols are a group, a reference signal and control information are sequentially sent, a first symbol in each group is used for transmitting DMRS, and a second symbol is used for transmitting DCI. For example, when X may take an even number of 2, 4, 6, 8, 10, etc.
Correspondingly, the method further comprises the steps of: RRC signaling controlling the set of resources is configured to indicate QCL information for the first type of symbol and the second type of symbol.
Illustratively, the first type of symbols occupied by the reference signals and the second type of symbols occupied by the control information within each symbol group have the same QCL information, i.e., are transmitted over the same beam; the symbols between different symbol groups may have the same QCL information or different QCL information, i.e. may be sent by the same beam or by different beams, and the QCL indication information is implemented by RRC signaling indication configuring the control resource set.
In some embodiments, the method further comprises: configuring detection indication information; the detection indication information is used for indicating a search space when the terminal equipment detects the control resource set. Here, the search space is to implement flexible scheduling among users, each terminal device is allocated with a control channel search space, and users need to blindly detect whether own control channels exist in the search space according to a predetermined rule.
Specifically, the detection indication information includes: the detection indication information comprises: an aggregation level indication and/or a start symbol position indication; wherein the aggregation level is in units of symbols.
Here, the aggregation level (Aggregation Level) is used to indicate the number of search symbols and the start symbol position is used to indicate the start symbol position of the search. The aggregation level in the prior art is divided into 4 levels, and the 4 levels correspond to 1, 2, 4 and 8 values, and represent the number of control channel elements (Control Channel Element, CCE) possibly occupied by the PDCCH of the terminal device, wherein the CCE is a basic unit of a physical Resource of the control channel, each CCE is composed of 9 Resource Element groups (Resource Element Group, REG), and each REG contains 4 available Resource Elements (REs). The starting position is used to indicate the starting CCE position of the blind detection.
In the embodiment of the present application, the aggregation level may introduce a new parameter slot aggregation level (Slot Aggregation Level, SAL), or multiplex an existing AL parameter configuration, but the physical meaning of the multiplexed AL is different from that of the existing AL, and the physical meaning of the AL after taking is the same as that of the newly introduced SAL.
The starting symbol position may be fixedly set to a symbol occupied by the first control information, or the starting symbol corresponding to the user equipment may be determined by the identification information of the user equipment.
The following is an illustration of a blind detection procedure for controlling a first and a second composition of a set of resources, respectively.
FIG. 5 is a first schematic diagram of a search space configuration in an embodiment of the present application; as shown in fig. 5, the control resource set includes 3 symbols, i.e., symbol # 0, symbol # 1, and symbol # 2, SAL1 represents a control channel candidate occupying 1 symbol, and SAL2 represents a control channel candidate occupying 2 symbols.
Specifically, SAL1 is configured as 1, which indicates that only the symbol occupied by the first control information of the control resource set is blindly detected, that is, symbol # 1, and the subsequent symbol is not blindly detected;
SAL1 is configured as 2, representing blind detection of symbol # 1 and symbol # 2, respectively, and not blind detection of symbol # 1 and symbol # 2 at the same time;
SAL2 is configured to be 1, indicating that symbol 1 and symbol 2 need to be detected blindly simultaneously;
SAL1 is configured as 1, SAL2 is configured as 1, which means that only the symbol occupied by the first control information of the control resource set is blindly detected, i.e. symbol # 1, and the subsequent symbol is not blindly detected; simultaneously blindly detecting symbol 1 and symbol 2;
SAL1 is configured as 1 and SAL1 is configured as 2, two symbols are detected, i.e., symbol # 1 and symbol # 2 are blind detected, respectively, while symbol # 1 and symbol # 2 are blind detected. Here, the simultaneous blind detection may be that different symbols transmit the same redundancy version (Redundancy Version, RV) or that different symbols transmit different RVs, and the terminal side performs the merging detection operation according to the configuration.
In practical applications, when SAL1 is configured to be 1, the starting symbol of blind detection may be fixedly set to the symbol occupied by the first control information, or the starting symbol corresponding to the user equipment may be determined through the identification information of the user equipment.
FIG. 6 is a second schematic diagram of a search space configuration in an embodiment of the present application; as shown in fig. 6, the control resource set includes 4 symbols, which are divided into 2 symbol groups, i.e., group # 0 and group # 1, SAL1 represents control channel candidates occupying 1 control resource group (2 symbols, reference signal symbol+control information symbol), SAL2 represents control channel candidates occupying 2 control resource groups (4 symbols).
Specifically, SAL1 is configured as 1, which indicates that only the symbol of the first symbol group of the control resource set, i.e., group # 0, is blind detected, and the symbols of other control resource groups are not blind detected;
SAL1 is configured as 2, representing blind detection of group # 0 and group # 1, respectively, without simultaneous blind detection of group # 0 and group # 1;
SAL2 is configured to be 1, indicating simultaneous blind detection of group # 0 and group # 1;
SAL1 is configured as 1 and SAL2 is configured as 1, indicating that only the symbols of the first symbol group of the control resource set, i.e., group # 0, are blindly detected, and that both group # 0 and group # 1 are blindly detected;
SAL1 is configured as 2 and SAL2 is configured as 1, indicating blind detection of group # 0 and group # 1, respectively, and simultaneous blind detection of group # 0 and group # 1; here, the simultaneous blind detection may be that different symbol groups transmit the same redundancy version (Redundancy Version, RV), or different symbol groups transmit different RVs, and the terminal side performs the merging detection operation according to the configuration.
In practical applications, when SAL1 is configured to be 1, the blind detected symbol group may be fixedly set to group # 0, or the starting symbol group corresponding to the user equipment may be determined through the identification information of the user equipment.
Here, depending on the design structure of the single carrier control resource set, the design of the search space based on the symbol level effectively utilizes the single carrier characteristic, has low implementation complexity and is easy to implement.
By adopting the technical scheme, when the control resource set is transmitted by adopting the single carrier waveform, the configured control resource set comprises the first type of symbols and the second type of symbols, the reference signal independently occupies the first type of symbols, and the control information independently occupies the second type of symbols, so that frequency division multiplexing of different control resource sets is avoided, and the control channel is transmitted by adopting the single carrier to ensure better coverage performance.

In practical application, the method further comprises the following steps: the scheduled data channel is implicitly indicated to adopt single carrier wave waveform transmission by configuring the frequency domain resource allocation domain in the DCI as the whole bandwidth of the BWP or preset frequency domain resource.
Specifically, the transmission waveform of the resource set is controlled by implicit indication of the resource allocation domain in the DCI domain. For example, if the scheduling bandwidth of the control resource set indicated by the resource allocation domain is the whole bandwidth of the frequency band, determining that the control resource set adopts single carrier wave waveform transmission; or the control resource set comprises a certain number of frequency domain resources, the frequency domain resources can take RBs as units, and when the number of the RBs occupied by the frequency domain resources is larger than a preset characteristic value (for example, the preset characteristic value is 20 RBs), the control resource set is determined to adopt single carrier wave waveform transmission.
