To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment explain in detail.
Referring to Fig.1, the embodiment of the invention provides a kind of PDSCH speed matching method, the method may include following
Step:
Step 11, when UE is configured for broadband PDCCH DMRS, detection is in the control resource set got in advance
No includes Downlink Control Information.
In specific implementation, UE is when carrying out PDSCH rate-matched, needs first to determine and can be used for PDSCH rate-matched
Resource.
REG as where broadband PDCCH DMRS is not only present in PDCCH can also be present in outside the REG where PDCCH
Some resources, thus need to can be used for PDSCH rate-matched using PDSCH speed matching method determination in the embodiment of the present invention
Resource.
UE may only get a control resource set (Control Resource Set, CORESET) in advance, it is also possible to
More than two CORESET are got in advance, and the quantity of the CORESET specifically got is with no restriction.Each CORESET is more
The set of a RE.Also, in accessed CORESET, CORERSET in PDCCH DMRS be narrowband DMRS, have
PDCCH DMRS in CORERSET is broadband DMRS.
In specific implementation, the quantity regardless of the UE CORESET got in advance, UE can be matched each respectively
It is set in the CORESET of broadband PDCCH DMRS and detects whether comprising Downlink Control Information (Downlink Control
Information, DCI), whether PDCCH transmission is used for the RE confirmed in the CORESET.
Step 12, when detecting Downlink Control Information in the control resource set got in advance, described in detection
Whether UE belongs to the situation outside the first restrictive condition.
Wherein, first restrictive condition includes: that the UE is configured for PDSCH rate-matched resource set, and is configured
PDSCH rate-matched resource set in the information comprising the control resource set where the Downlink Control Information.
In specific implementation, when there are when DCI, show that part resource is utilized as in the CORESET in CORESET
PDCCH data transmission, therefore it needs to be determined that in CORESET PDSCH rate-matched resource, so that UE can be properly received PDSCH
Data.
Currently, 5G NR supports to be that UE configures at most 4 PDSCH rates by higher level parameters Resource-set-BWP
With resource set (Rate-match-PDSCH-resource-set).Each PDSCH rate-matched resource set is to be not useable for
PDSCH transmission and need to do PDSCH rate-matched RE set.It may include UE oneself in PDSCH rate-matched resource set
CORESET information, it is also possible to the information of the CORESET not comprising UE oneself.Wherein, the CORESET of the UE oneself
Information may include the ID of the ID of CORESET and the ID of search space associated with the CORESET, UE according to CORESET
The available frequency domain information to CORESET can pass through the prison of the search space corresponding to the ID according to the ID of search space
Listen the time-domain information for getting CORESET constantly.
When in PDSCH rate-matched resource set including the information of CORESET, 5G NR supports base station using DCI dynamically
Whether indicating section or whole CORESET can be used for PDSCH rate-matched.Specifically, base station can use DCI indicating section
Or whole CORESET can be used for PDSCH rate-matched, can also indicate that all or part of CORESET cannot be used for
PDSCH rate-matched.
Existing 3GPP agreement only gives the PDSCH rate that UE is configured for PDSCH rate-matched resource set and is configured
When matching the information comprising the CORESET where the DCI in resource set, the solution of PDSCH rate-matched, for other
The solution of situation not yet provides.
In an embodiment of the present invention, the UE is configured for PDSCH rate-matched resource set, and configured
Information comprising the CORESET where the DCI in PDSCH rate-matched resource set, as the first restrictive condition.
In specific implementation, in the case of outside the first restrictive condition, may include it is a variety of, specifically with no restriction.For example,
UE may not be configured PDSCH rate-matched resource set；Alternatively, UE is configured for PDSCH rate-matched resource set, but configured
PDSCH rate-matched resource set in do not include CORESET information；Alternatively, UE is configured for PDSCH rate-matched resource
Collection, and comprising the information of CORESET in the PDSCH rate-matched resource set configured, but the CORESET information for being included is corresponding
CORESET be the resource for being not useable for PDSCH rate-matched.
In specific implementation, base station can be indicated in configured PDSCH rate-matched resource set by DCI
The corresponding CORESET of the information of CORESET, if be not useable for PDSCH rate-matched.It is of course also possible to use other way
Instruction, specifically with no restriction.
Step 13, when the UE belongs to the situation outside the first restrictive condition, using the RE in first set as can be used for
The resource of PDSCH rate-matched, and carry out PDSCH rate-matched.
Wherein, the first set includes: the downlink control in the control resource set where the Downlink Control Information
RE shared by RE shared by the information and broadband PDCCH DMRS.
In specific implementation, a resource block (Resource Block, RB) RE structure shared in an OFDM symbol
At a REG.It include 12 RE in one REG.CORESET is continuous in the time domain, but may be continuous on frequency domain, it is also possible to no
Continuously.
In specific implementation, when CORESET is discontinuous on frequency domain, the continuous portion of the DCI is included in the CORESET
It point may include: all RE in the REG where the PDCCH DMRS of broadband.Since PDCCH DMRS is configured as broadband, because
Have in multiple REG where the PDCCH DMRS of this broadband there are DCI on the REG of part, there is no DCI by remaining REG, and are depositing
There are 9 RE for DCI in each REG of DCI, is left 3 RE and is used for DMRS, is i.e. number is the RE of #1, #5, #9 in REG.
In one embodiment of this invention, can be by the CORESET where DCI, RE shared by DCI and broadband
RE shared by PDCCH DMRS, the resource as PDSCH rate-matched.
In another embodiment of the invention, can also be by the CORESET where DCI, RE shared by DCI and broadband
The union of all RE in REG where PDCCH DMRS is as the first set.
For example, UE is configured for 1 CORESET-1, the time domain length of the CORESET-1 is 2 OFDM symbols, on frequency domain
Discontinuously, and on frequency domain be divided into three sections: first segment accounts for 18 RB, and second segment accounts for 36 RB, and third section accounts for 42 RB, and totally 96
RB.In the CORESET-1, PDCCH DMRS is configured as broadband DMRS.
If UE monitors the CORESET-1 in n-th of time slot and detects a DCI, base station may be adjusted by the DCI
The PDSCH of n-th of time slot is spent.The DCI accounts for 2 symbols in the time domain, and 6 RB are accounted on frequency domain.Due to interweaving, which may
It is dispersed on the first segment and second segment of CORESET-1, so that broadband PDCCH DMRS accounts for continuous portion of the CORESET-1 containing DCI
Point, i.e., all REG on first segment and second segment.
At this point, the first set can be for shared by RE and broadband PDCCH DMRS shared by DCI in CORESET-1
RE accounts for 3 RE that number is #1, #5, #9 since broadband PDCCH DMRS is fixed on each REG, then shares 6*2*9+ (18+
36) * 2*3=432 RE is the resource of PDSCH rate-matched.
The first set may be RE shared by the DCI and REG where the PDCCH DMRS of broadband in CORESET-1
The union of interior all RE, i.e. CORESET-1 include the continuous part of DCI, and shared (18+36) * 2*12=1296 RE is
The resource of PDSCH rate-matched.
In one embodiment of this invention, as CORESET, consecutive hours, the CORESET include the company of the DCI on frequency domain
Continuous part, i.e., entire CORESET.At this point it is possible to using entire CORESET as the first set, i.e. where DCI
All RE are the resource of PDSCH rate-matched in CORESET.
For example, UE is configured for 1 CORESET-2, the time domain length of the CORESET-2 is 2 OFDM symbols, on frequency domain
Account for 96 resource blocks (Resource Block, RB).In the CORESET-2, PDCCH DMRS is configured as broadband DMRS.
If UE monitors the CORESET-2 in n-th of time slot and detects a DCI, base station may be adjusted by the DCI
The PDSCH of n-th of time slot is spent, it is also possible to scheduled the PDSCH of other time slots.At this point, UE can be by detected DCI institute
CORESET (i.e. CORESET-2) in all RE as the resource that can be used for PDSCH rate-matched, then share 96*2*12=
2304 RE are the resource of PDSCH rate-matched.
