For example, the resource that the overlapping region 3 of PDCCH channel 1 and PDSCH are covered is reusable to PDSCH with reference to Fig. 2 The resource of channel 2, wherein m-th of resource is the described first reserved resource, cannot be multiplexed and use to PDSCH channel 2.Wherein, The first reserved resource can be reserved to the control resource of the PDCCH channel 1 for the network side；Described first reserved money Source, which can be, is reserved to the user equipment for receiving the notice grid, is also possible to be reserved to other users equipment.
Further, the grid can be the control resource grid on system band (system band).As one A non-limiting embodiment, the grid can be constructed based on the prior art.For example, with continued reference to Fig. 2, the PDCCH The resource that channel 1 uses may include T orthogonal frequency division multiplexing (Orthogonal Frequency Division in the time domain Multiplexing, abbreviation OFDM) symbol, since the grid can be implemented in the resource that the PDCCH channel 1 uses It above and include M resource block, thus, the grid may include M/T resource on the frequency domain of the PDCCH channel 1. T OFDM symbol in time domain and M/T resource on frequency domain collectively constitute the M resource block.
It will be appreciated by those skilled in the art that theoretically, the M resource block is applied to control resource, the control resource One or more user equipmenies can be distributed to.But in practical applications, the M resource block very likely occurs vacant State, in order to improve resource utilization, existing protocol provides to need to allow to believe the resource multiplex in blank state to PDSCH Road uses.The technical solution of the present embodiment is used for solving the problems, such as how preferably to improve resource multiplex efficiency, so that network Can by PDCCH channel for the resource (hereinafter referred to as recoverable resources) of PDSCH channel multiplexing being indicated to easily and fast User equipment；Meanwhile user equipment also can be under the premise of not increasing expense, quick obtaining recoverable resources is in grid On specific location, to improve resource multiplex rate.
Preferably, the resource block that the grid includes may include in new wireless (New Radio, abbreviation NR) system The control resource set (Control Resource Set, abbreviation CORESET) of PDCCH channel.
It further, may include: by high-level signaling (higher-layer before executing the step S101 Signaling building information and the notice of the grid in the resource that the PDCCH channel uses) are indicated Building information of the grid in the resource that the overlapping region of the PDCCH channel and PDSCH channel uses.
For example, the network can indicate the system to the user equipment of all accesses in advance in a manner of high-level signaling The length T of the resource block quantity M and the grid that grid includes in the time domain.For example, the network can be with broadcast Mode transmit the high-level signaling.
Alternatively, the network can also indicate institute in network to the user equipment of all accesses in advance by way of broadcast There is distribution information of the corresponding CORESET of user equipment on PDCCH channel, so that each user equipment determines the system network Building information of the lattice in the resource that the PDCCH channel uses.
Further, the configuration information of the PDCCH channel can pass through Downlink Control Information (Downlink Control Information, abbreviation DCI) it is indicated to user equipment, so that the user equipment can obtain the PDCCH channel and use Resource position, and then determine the resource division information of the grid.

As a non-limiting embodiment, with reference to Fig. 2, the sign bit occupied in the time domain according to the PDCCH channel 1 It sets and the PDSCH channel 2 beginning character position in the time domain, can determine the PDCCH channel 1 and PDSCH channel 2 There is overlapping in the resource used, the resource that overlapping region 3 includes is that the building basis of grid is notified described in the present embodiment.
Further, based on scheme described in the present embodiment, the notice grid can be exclusively used in identifying the overlapping region 3 The middle resource that can be re-used can be according to the reserved money of first wherein identified after user equipment receives the notice grid The resource being re-used in the overlapping region 3 to PDSCH channel is reversely extrapolated in the position in source.
It is similar with the grid as a non-limiting embodiment, before executing the step S101, institute Stating network can also indicate that the notice grid includes to the user equipment of all accesses in advance by way of high-level signaling The length Td of resource grid quantity K and the notice grid in the time domain, so that the user equipment can obtain the notice Building information of the grid in the resource that the overlapping region of the PDCCH channel and PDSCH channel uses.Alternatively, the network The isoboles that can also indicate the notice grid to the user equipment of all accesses by way of the high-level signaling, such as scheme Grid dividing figure shown in overlapping region 3 shown in 2.
As a non-limiting embodiment, in scheduling phase, the network can be useful for the institute for accessing its network Family equipment optimizes, to determine the grid and notice grid of distributing to each user equipment.Wherein, the grid It can be unique；The notice grid is also possible to uniquely, alternatively, the notice grid can also be with the user equipment It is corresponding.For example, low for data rate and narrower bandwidth user equipment, the notice grid only need to include lesser resource Lattice quantity (i.e. lesser K value) can sufficiently accurate instruction multiplexed resource position, to reduce the corresponding notice grid position of transmission Data transmission ratio needed for figure is special, is conducive to user equipment faster to receive to include the DCI for notifying grid bitmap, in turn Improve the multiplexed resource utilization rate of user equipment.
Further, in the scheduling phase, after determining the grid, the network can determine described Corresponding position of the resource of control on the grid is reserved in the resource that PDCCH channel uses (alternatively referred to as to reflect Penetrate position).
Further, according to distributing to resource that the PDSCH channel and PDCCH channel respectively use in the system network Corresponding position on lattice can determine pair of the resource of the PDSCH channel and PDCCH channel multiplexing on the grid Position is answered, and then determines corresponding position of the first reserved resource on the grid.
Further, the step S102 is needed to be implemented, by the described first reserved resource on the grid Corresponding position map to its it is described notice grid on corresponding position, on the basis of reducing signalling expense to user Equipment indicates corresponding position of the described first reserved resource on the grid.
As a non-limiting embodiment, the step S102 may include: to obtain the first reserved resource in institute The grid identification information on grid is stated, the grid identification information exists for identifying the described first reserved resource Position on the grid；The grid identification information is mapped into corresponding notice grid on the notice grid Identification information, the notice Marking the cell information are used to identify equivalent bit of the described first reserved resource on the notice grid It sets.
For example, with continued reference to Fig. 2, m-th of resource as the described first reserved resource is on the grid Marking the cell information of uniting is grid identification information m.
In another example m-th of resource as the described first reserved resource is equivalent on the notice grid with reference to Fig. 3 Corresponding notice Marking the cell information may include notice Marking the cell information k1 and notice Marking the cell information k2 at position.
As a non-limiting embodiment, with reference to Fig. 3 and Fig. 4, the notice grid can be implemented in the PDCCH letter The frequency domain resource that road 1 and PDSCH channel 2 are multiplexed, alternatively, the notice grid can be implemented in described with reference to Fig. 5 and Fig. 6 On the frequency domain and time-domain resource that PDCCH channel 1 and PDSCH channel 2 are multiplexed.
Wherein, the notice grid shown in Fig. 3 and Fig. 4 only covers frequency domain resource, is based on grid in the time domain What resource in the time domain was allocated；Notice grid shown in Fig. 5 and Fig. 6 then covers the money in time domain and frequency domain simultaneously Source.
Wherein, Fig. 3 and Fig. 5 is compared, the bandwidth that Fig. 4 and PDSCH channel shown in fig. 6 occupy on frequency domain is wider, thus The resource of the notice grid can cover the region of more grids, still, notice grid bitmap institute on frequency domain The transmitted bit number needed is still K bit.
Further, the granularity of division of the notice grid and the granularity of division of the grid can be identical, can also With not identical.
In a preferred embodiment, described that the grid identification information is mapped into corresponding on the notice grid lead to Know Marking the cell information may include: when it is described notice grid granularity of division be less than the grid granularity of division when, The grid identification information can be mapped to corresponding multiple notice Marking the cell information on the notice grid.
For example, kth 1 money in m-th of resource and the notice grid with reference to Fig. 3 and Fig. 5, on the grid 2 resource overlappings in source and kth, therefore, it is possible to the grid identification information m be mapped to corresponding on the notice grid Notify Marking the cell information k1 and notice Marking the cell information k2.
It is described that the grid identification information is mapped into corresponding on the notice grid lead to as a change case Know that Marking the cell information can also include: when the granularity of division of the notice grid is greater than the granularity of division of the grid When, the grid identification information can be mapped to corresponding one or more notice Marking the cells on the notice grid Information.
For example, with reference to Fig. 4, m-th of resource on the grid only with 1 resource of kth on the notice grid A part overlap, therefore, it is possible to which the grid identification information m is mapped to corresponding notice on the notice grid Marking the cell information k1.
In another example with reference to Fig. 6, m-th of resource on the grid respectively with kth 1 on the notice grid A part of resource of 2 resources of a part of resource and kth of resource overlaps, and believes therefore, it is possible to which the grid is identified Breath m maps to corresponding notice Marking the cell information k1 and notice Marking the cell information k2 on the notice grid.
Further, when bandwidth of the PDSCH channel on frequency domain is smaller, stroke of the notice grid in the time domain Gradation degree might be less that the granularity of division of the grid in the time domain, effectively to ensure and improve resource multiplex rate.
For example, with reference to Fig. 7, m-th of resource on the grid and 1 resource of kth on the notice grid, the 4 k2 resource, 3 resources of kth and kth resource overlappings, therefore, it is possible to which the grid identification information m is mapped to institute State notice grid on corresponding notice Marking the cell information k1, notice Marking the cell information k2, notify Marking the cell information k3 and Notify Marking the cell information k4.
Further, the granularity of division of the notice grid can be the resource grid quantity for including according to the notice grid What the comparison result for the resource block quantity that the PDCCH channel that K and grid include uses determined.Wherein, the notice grid Granularity of division can at least be selected from: resource block；Subcarrier；Wherein, the resource block includes multiple subcarriers.For example, described Resource block can be Physical Resource Block (Physical Resource Block, abbreviation PRB), and a Physical Resource Block can wrap Include 12 subcarriers (subcarrier).As a non-limiting embodiment, the PDCCH channel that the grid includes makes Resource block quantity can be M.
In a typical application scenarios, by taking granularity of division of the notice grid on frequency domain as an example, due to described Notice grid is limited to the PDSCH channel in the bandwidth on frequency domain on frequency domain, and the notice grid is on frequency domain K/Td resource (hereinafter referred to as quantity W can be divided intof), PDSCH channel is distributed in the resource of grid covering The resource quantity used can be denoted as quantity WPDSCH, default using Physical Resource Block as allocation unit.For example, working as the notice grid It is less than the grid in the resource quantity divided on frequency domain in the resource quantity (K/Td) that can be divided on frequency domain, it can be with Using the Physical Resource Block as allocation unit.In another example as the resource quantity (K/ for notifying grid that can divide on frequency domain Td) it is greater than the grid in the resource quantity divided on frequency domain, it can be using the subcarrier as allocation unit.
Work as WPDSCH>WfWhen, it can be granularity of division of the notice grid on frequency domain, reference with the Physical Resource Block Fig. 8, since PDSCH channel in the grid on frequency domain resource (NPDSCH) rise, for preceding Wf1 notice grid exists Resource on frequency domain, wherein each resource can map to the W on the grid1A resource, wherein W1=floor (WPDSCH/Wf), the floor () function is downward bracket function.And the last one resource on frequency domain of notice grid can be with Map to (Wf-1)×W1W after a resource2A grid resource, wherein W2=WPDSCH–(Wf-1)×W1.Final effect Division effect of the notice grid on overlapping region 3 with reference to shown in Fig. 4.
Work as WPDSCH<WfAnd 12 × WPDSCH>WfWhen, it can be described logical with subcarrier (i.e. the minimum unit of ofdm system) Granularity of division of the Hownet lattice on frequency domain, with reference to Fig. 9, since PDSCH channel in the grid on frequency domain resource (NPDSCH) rise, for preceding WfResource of -1 notice grid on frequency domain, wherein each resource can map to the system The W to unite on grid1A resource, wherein W1=floor (12 × WPDSCH/Wf).And the last one money of notice grid on frequency domain Source can map to (Wf-1)×W1W after a resource2A grid resource, wherein W2=12 × WPDSCH–(Wf-1)× W1.The final effect division effect of notice grid on overlapping region 3 with reference to shown in Fig. 3.
Otherwise, as 12 × WPDSCH<WfWhen, it can also be division grain of the notice grid on frequency domain with subcarrier Degree, with reference to Figure 10, since PDSCH channel in the grid on frequency domain resource (NPDSCH) rise, preceding 12 × WPDSCHIt is a Notice gridding resource can be respectively mapped to a subcarrier of the grid.
Further, the granularity of division of the notice grid is also selected from control channel element (Control Channel Element, abbreviation CCE) or resource element beam combination (Resource Element Group bundle, abbreviation REG bundle)。
Further, non-uniform can also be to the division of the notice grid, that is, a notice grid is in time domain With may each comprise multiple granularity of division on frequency domain.For example, for control zone that the length in time domain is 3 OFDM symbols and when Length is the notice grid of 2 resources on domain, the 1st OFDM symbol of the control zone can be mapped to the notice grid 2nd and the 3rd OFDM symbol of the control zone is mapped to the notice grid in time domain by first resource in the time domain On second resource；Alternatively, the 1st and the 2nd OFDM symbol of the control zone can also be mapped to the notice grid 3rd OFDM symbol of the control zone is mapped to the notice grid in the time domain by first resource in the time domain Second resource.
Further, the resource and the PDCCH channel and PDSCH channel that PDCCH channel uses described in the present embodiment The resource that uses of overlapping region all can be physical resource (physical resource)；Or, or map to institute State the virtual resource (virtual resource) of physical resource.
Further, the distribution of the PDCCH channel in the time domain (or in time domain and frequency domain) can be discontinuously , correspondingly, the resource area that the overlapping region that multiple PDCCH channels and PDSCH channel can occur uses.
As a non-limiting embodiment, the grid can be on frequency domain and/or frequency domain it is discontinuous, and And it can be Chong Die with the CORESET of PDCCH channel.

Alternatively, in the tolerance interval that signaling overheads increases, it can also be targeted for each resource area Notice grid is separately designed, so that the notice grid for being mapped to each resource area can be with original system in the resource area Grid preferably matches.
By upper, using the scheme of the present embodiment, while retaining original system grid, also definition notifies grid, with mark Remember distribution information of the resource used for PDSCH channel in control channel area (resource that such as PDCCH channel uses), wherein It is including the OFDM of control channel that the notice grid, which can be and be implemented in the PDSCH channel and distribute in time domain and frequency domain, The resource of symbol.
It will be appreciated by those skilled in the art that the notice grid is capable of providing a kind of variable resource multiplex scheme, it is described logical Hownet lattice can change as the distribution of PDSCH channel changes, so that while maintaining DCI length constant, and being capable of spirit The granularity of division living for adjusting notice grid.For example, for lesser PDSCH channel distribution, (such as described PDSCH channel is on frequency domain Bandwidth it is smaller), resource multiplex rate can be promoted with lesser granularity of division.
Further, the transmitted bit number as needed for the notice grid bitmap of transmission is only that K bit (is less than existing system M-bit needed for grid bitmap), the content for including needed for the DCI can be greatly reduced, so that the DCI more compresses (compact).On the other hand, since the resource grid constant number that the notice grid includes is K, so that the notice grid The size of bitmap will not change as bandwidth of the PDSCH channel on frequency domain changes, and then ensure the length of the DCI Constant is constant, avoids multiple blind examination, will not increase blind examination amount.
