Referring to fig. 2, Fig. 2 is a kind of flow chart of communication means provided in an embodiment of the present invention, is applied to network side equipment, As shown in Figure 2, comprising the following steps:
If step 201, there are Chong Die, roots with the candidate running time-frequency resource of synchronization signal block SSB by control resource group CORESET According to the target system information that physical downlink control channel PDCCH is dispatched, target running time-frequency resource is determined in the CORESET.
In the embodiment of the present invention, network side equipment can be according to the position of the candidate running time-frequency resource of SSB, CORESET time-frequency The position of resource, determine CORESET whether with the candidate running time-frequency resource of each SSB there are Chong Die, if network side equipment determines There are Chong Die, the then PDCCH scheduling of the available CORESET transmission of network side equipment with the candidate running time-frequency resource of SSB by CORESET Target system information, and according to target system information in CORESET determine target running time-frequency resource.When the candidate of above-mentioned SSB Frequency resource is the running time-frequency resource that can be used for sending the SSB.
Wherein, above-mentioned CORESET can be that there are resources is overlapping with the candidate running time-frequency resource of a SSB, be also possible to same When that there are resources is overlapping with the candidate running time-frequency resource of multiple SSB, be not defined herein.
Step 202 maps the PDCCH on the target running time-frequency resource, and joins with the associated demodulation of the PDCCH Examine signal DMRS；
Step 203 sends the PDCCH on the target running time-frequency resource, and with the associated DMRS of the PDCCH.
In the embodiment of the present invention, if determination target running time-frequency resource in above-mentioned steps 201, network side equipment can be incited somebody to action The PDCCH and the associated demodulated reference signal of the PDCCH (Demodulation Reference of CORESET transmission Signal, DMRS) it is mapped on target running time-frequency resource, and PDCCH and DMRS is sent on target running time-frequency resource.
It should be noted that above-mentioned target system information may include remaining minimum system information (Remaining Minimum system information, RMSI) and other systems information (Other System Information, OSI any one of), and above-mentioned other systems information may include except Master Information Block (Master Information Block, MIB the system information except other systems information OSI) and except the RMSI.
In addition, in the embodiment of the present invention, the above-mentioned target system information dispatched according to PDCCH determines mesh in CORESET Running time-frequency resource is marked, can be the corresponding running time-frequency resource determination side of each system information that network side equipment is pre-configured with PDCCH scheduling Formula, when network side equipment gets the target system information of PDCCH scheduling, according to the corresponding running time-frequency resource of target system information Method of determination determines that the running time-frequency resource in CORESET is target running time-frequency resource.
Optionally, if CORESET and the candidate running time-frequency resource of SSB are there are Chong Die, and the goal systems of PDCCH scheduling Information is the first system information, then is determined as the running time-frequency resource in the CORESET in addition to the running time-frequency resource of overlapping described Target running time-frequency resource, wherein the first system information includes RMSI, thus make when user terminal carries out blind Detecting, it can be with Correctly solve RMSI PDCCH.
In present embodiment, when the system information of PDCCH scheduling is RMSI, network side equipment is sent to user terminal Carried in SSB including RMSI PDCCH configuration information (i.e. RMSI-PDCCH-config information, also referred to as PdcchConfigSIB1 information) Master Information Block (master information block, MIB), and RMSI PDCCH configure Information can provide the configuration information of the corresponding RMSI CORESET of the SSB for user terminal and and user be helped to determine monitoring The opportunity of PDCCH, the i.e. position of PDCCH monitor window.The configuration information of RMSI CORESET include CORESET time domain duration, The information such as frequency domain bandwidth, frequency domain position.Therefore, when user terminal determines RMSI by the configuration information of RMSI CORESET When CORESET has overlapping with the candidate running time-frequency resource of corresponding SSB, user terminal can assume network side equipment in RMSI It is associated that the RMSI PDCCH and RMSI PDCCH is sent on running time-frequency resource in CORESET in addition to the running time-frequency resource of overlapping Demodulated reference signal (Demodulation Reference Signal, DMRS), therefore to avoid user terminal to RMSI PDCCH The running time-frequency resource used assumes mistake, leads to not be correctly detecting RMSI PDCCH to can not possibly even solve RMSI PDCCH, network side equipment is using the running time-frequency resource in RMSI CORESET in addition to the running time-frequency resource of overlapping as when above-mentioned target Frequency resource.
By taking the distribution of the candidate running time-frequency resource of CORESET and SSB as shown in Figure 3a as an example, RMSI CORESET1 with There are corresponding relationships by SSB1, if there are Chong Die with the candidate running time-frequency resource of SSB1 by network side equipment confirmation RMSI CORESET1 Running time-frequency resource, such as symbol 2, the candidate running time-frequency resource that SSB1 can be used in network side equipment sends SSB1, and is sending RMSI When CORESET1, on the running time-frequency resource in RMSI CORESET1 on divided-by symbol 2 except lap send RMSI PDCCH with And with the associated DMRS of RMSI PDCCH；And when user terminal receives SSB1, if obtaining RMSI by decoding SSB1 The bandwidth of CORESET1 is 24RB, and time domain length is 3 OFDM symbols, and in the monitor window of RMSI CORESET1, is determined RMSI CORESET1 and the candidate running time-frequency resource of SSB1 are there are Chong Die on symbol 2, then user terminal is in RMSI CORESET1 Blind Detecting RMSI PDCCH on running time-frequency resource on middle divided-by symbol 2 except lap.
In addition, if the system information of PDCCH scheduling is RMSI, and network side equipment confirms a RMSI CORESET and SSB Candidate running time-frequency resource exist overlapping and SSB the and RMSI CORESET between be not present corresponding relationship, work as network side equipment To user terminal on two different wave beams of direction, when sending the SSB and SSB corresponding with RMSI CORESET respectively, Where being not in the SSB due to user terminal in beam area, user terminal can not be true when high-level signaling instruction has not been obtained Recognize whether the SSB actually sends, user terminal can assume that network side equipment will remove the time-frequency of overlapping in RMSI CORESET at this time Running time-frequency resource except resource is that user terminal is avoided to there is weight in RMSI CORESET as above-mentioned target running time-frequency resource On the running time-frequency resource of folded part, RMSI PDCCH can not be received and lead to not solve RMSI PDCCH, network side equipment will Running time-frequency resource in RMSI CORESET in addition to the running time-frequency resource of overlapping is as above-mentioned target running time-frequency resource.Above-mentioned high-level signaling It indicates to include at least one in the instruction of wireless heterogeneous networks (Radio Resource Control, RRC) signaling and RMSI instruction ?.
By taking the distribution situation of the candidate running time-frequency resource of CORESET and SSB as shown in Figure 3b as an example, RMSI CORESET1 There are corresponding relationship and RMSI CORESET2 and SSB2, there are corresponding relationships with SSB1, if network side equipment confirms RMSI CORESET2 and the candidate running time-frequency resource of SSB1 are there are Chong Die running time-frequency resource, and such as symbol 2 and symbol 3, and network side equipment exists On two different wave beams of direction, SSB1 is sent using the candidate running time-frequency resource of SSB1, is sent using the running time-frequency resource of SSB2 SSB2, and the running time-frequency resource in RMSI CORESET2 on divided-by symbol 2 and symbol 3 except lap sends RMSI PDCCH And with the associated DMRS of RMSI PDCCH；And when user terminal receives SSB2, if obtaining RMSI by decoding SSB2 The bandwidth of CORESET2 is 24RB, and time domain length is 2 OFDM symbols, and in the monitor window of RMSI CORESET2, is determined RMSI CORESET2 and the candidate running time-frequency resource of SSB1 are there are Chong Die on symbol 2 and symbol 3, and user terminal is not because receiving RMSI is indicated and can not be confirmed whether network side equipment sends SSB1, then user terminal assumes network side equipment in RMSI Send RMSI PDCCH and DMRS on running time-frequency resource in CORESET2 on divided-by symbol 2 and symbol 3 except lap, and Blind Detecting RMSI PDCCH on running time-frequency resource in RMSI CORESET2 on divided-by symbol 2 and symbol 3 except lap.
Again by taking the distribution of the candidate running time-frequency resource of CORESET and SSB as shown in Figure 3c as an example, RMSI CORESET2 with There are corresponding relationships by SSB2, but corresponding relationship is not present with SSB1, if the candidate running time-frequency resource of RMSI CORESET2 and SSB1 are deposited In the running time-frequency resource of overlapping, such as symbol 2 and symbol 3, and network side equipment only has sent SSB2 and not sent SSB1, and works as user When terminal receives SSB2, the bandwidth that RMSI CORESET2 is obtained by decoding SSB2 is 24RB, and time domain length is 2 OFDM Symbol, and in the monitor window of RMSI CORESET2, determine the candidate running time-frequency resource of RMSI CORESET2 and SSB1 in symbol 2 It is overlapped with existing on symbol 3, since user terminal can not confirm whether network side equipment sends SSB1, then user terminal assumes net Network side apparatus sends RMSI on the running time-frequency resource in RMSI CORESET2 on divided-by symbol 2 and symbol 3 except lap PDCCH and DMRS, and blind examination on the running time-frequency resource in RMSI CORESET2 on divided-by symbol 2 and symbol 3 except lap Survey RMSI PDCCH, thus, network side equipment in RMSI CORESET2 on divided-by symbol 2 and symbol 3 except lap when In frequency resource, RMSI PDCCH and DMRS are sent, to avoid user terminal that from can not solving RMSI PDCCH.
Alternatively, optional, if there is Chong Die, and the mesh that the PDCCH is dispatched with the candidate running time-frequency resource of SSB in CORESET Mark system information is second system information, it is determined whether sends that there are the Chong Die SSB of resource with the CORESET, wherein institute Stating second system information includes the other systems information OSI in addition to Master Information Block MIB and the RMSI；If it is determined that send with There are the SSB that resource is overlapped by the CORESET, then by the running time-frequency resource in the CORESET in addition to the running time-frequency resource of overlapping It is determined as the target running time-frequency resource.
Wherein, if PDCCH scheduling system information be OSI, and if CORESET an and SSB candidate running time-frequency resource presence Overlapping, then after user terminal receives the SSB of network side equipment transmission, user terminal is available to be indicated to high-level signaling, And determine that there are the Chong Die SSB of resource whether to send with CORESET according to high-level signaling instruction, and when user terminal is determining and When practical there are the SSB that running time-frequency resource the is overlapped transmission of CORESET, user terminal determines network side equipment in CORESET except weight OSI PDCCH and DMRS are sent on running time-frequency resource except folded running time-frequency resource.
Certainly, further alternative, it is above-mentioned to determine whether to send with the CORESET there are after the Chong Die SSB of resource, If it is determined that not sending, there are the Chong Die SSB of resource with the CORESET, then the running time-frequency resource comprising overlapping in CORESET exist Interior running time-frequency resource is determined as the target running time-frequency resource.In this way, if the system information of PDCCH scheduling is OSI, when network side is set It is standby not sent with CORESET there are when the Chong Die SSB of resource, time-frequency of the network side equipment in CORESET comprising being overlapped provides The associated DMRS of OSI PDCCH and OSI PDCCH is sent on running time-frequency resource including source, promotes running time-frequency resource in CORESET Utilization rate；And user terminal can be indicated by the high-level signaling of acquisition, it is determining that there are the SSB that resource is Chong Die with CORESET Reality is sent, then blind Detecting OSI on the running time-frequency resource including the running time-frequency resource comprising overlapping in user terminal CORESET PDCCH。
By taking the distribution situation of the candidate running time-frequency resource of CORESET and SSB as shown in Figure 3c as an example, if RMSI CORESET With OSI CORESET be multiplexed, and RMSI CORESET2 simultaneously by OSI CORESET be multiplexed and RMSI CORESET2 with There are corresponding relationships by SSB2, but corresponding relationship is not present with SSB1, and the candidate running time-frequency resource of RMSI CORESET2 and SSB1 exist The running time-frequency resource of overlapping, such as symbol 2 and symbol 3；When network side equipment sends SSB2 and practical transmission SSB1, network side is set It is standby can the running time-frequency resource comprising lap on symbol 2 and symbol 3 in RMSI CORESET2 send OSI PDCCH and its Associated DMRS；And when network side equipment sends SSB1 and SSB2, network side equipment divided-by symbol 2 in RMSI CORESET2 With transmission OSI PDCCH and associated DMRS on the running time-frequency resource except lap on symbol 3.
The distribution of the candidate running time-frequency resource of above-mentioned CORESET and SSB is as shown in Figure 3c, and RMSI CORESET and OSI In the example of CORESET multiplexing, if user terminal receives SSB2, the bandwidth of RMSI CORESET2 is obtained by decoding SSB2 For 24RB, time domain length is 2 OFDM symbols, and in the monitor window of RMSI CORESET2, determine RMSI CORESET2 with There is overlapping in the candidate running time-frequency resource of SSB1, then user terminal is indicated according to the RMSI received on symbol 2 and symbol 3, when When determining that SSB1 is actually not sent, user terminal in RMSI CORESET2 comprising on symbol 2 and symbol 3 lap when Blind Detecting OSI PDCCH in frequency resource；And when determining the practical transmission of SSB1, user terminal is in RMSI CORESET2 except symbol Numbers 2 and symbol 3 on blind Detecting OSI PDCCH on running time-frequency resource except lap.
In addition, by taking network side equipment determines the candidate running time-frequency resource presence overlapping of an OSI CORESET and SSB as an example, if Running time-frequency resource OSI CORESET Chong Die with the SSB includes symbol 2 and symbol 3, as the practical not sent SSB of network side equipment When, then network side equipment can be sent on the running time-frequency resource comprising lap on symbol 2 and symbol 3 in OSI CORESET OSI PDCCH and associated DMRS；And when network side equipment is practical send the SSB when, network side equipment can be in OSI OSI PDCCH and associated is sent on running time-frequency resource in CORESET2 on divided-by symbol 2 and symbol 3 except lap DMRS。
And the above network side equipment determines that the candidate running time-frequency resource of an OSI CORESET and SSB exists in the example of overlapping, If user terminal receives SSB, decoding discovery OSI CORESET bandwidth is 24RB, and the symbol that time domain occupies is symbol 2 and symbol 3, and in the monitor window of OSI CORESET, the candidate running time-frequency resource of a confirmation OSI CORESET and SSB has overlapping, then user RMSI is indicated terminal based on the received, when determining actually not sent there are the Chong Die SSB of resource with OSI CORESET, user Terminal can blind Detecting OSI PDCCH on the running time-frequency resource comprising lap on symbol 2 and symbol 3 in OSI CORESET； And when determining transmission practical there are the Chong Die SSB of resource with OSI CORESET, user terminal is in OSI CORESET except symbol Numbers 2 and symbol 3 on blind Detecting OSI PDCCH on running time-frequency resource except lap.
It should be noted that above-mentioned user terminal obtains high-level signaling instruction, it can be user terminal acquisition and be pre-configured with High-level signaling instruction, be also possible to user terminal based on the received SSB obtain in real time high-level signaling instruction, herein and without It limits.
In addition, above-mentioned user terminal determine CORESET whether with the candidate running time-frequency resource of SSB there are Chong Die, can be use Family terminal receives the SSB that network side equipment is sent, which includes the running time-frequency resource configuration information of CORESET and the prison of PDCCH Information is controlled, and the SSB can be with CORESET there are the Chong Die SSB of resource, is also possible to that resource weight is not present with CORESET Folded SSB, user terminal can be accurately determined according to the resource allocation information of CORESET and the monitoring information of PDCCH Whether there are Chong Die with the candidate running time-frequency resource of any SSB by CORESET.
In addition, user terminal can also monitor RMSI in the monitor window of CORESET according to PDCCH monitoring information PDCCH, to obtain RMSI Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), RMSI The information and OSI relevant information of the instruction practical SSB sent of network side equipment are contained in PDSCH；And it is obtained in user terminal After obtaining RMSI PDSCH, user terminal can also monitor OSI PDCCH in the monitor window of CORESET, to obtain OSI PDSCH, so that user terminal be allow to determine the practical SSB sent of network side equipment when monitoring OSI PDCCH.
In the embodiment of the present invention, by the target system information dispatched according to PDCCH, when determining target in CORESET Frequency resource, and PDCCH is sent on target running time-frequency resource, and with the associated demodulated reference signal DMRS of PDCCH, keep user whole End receives PDCCH and DMRS on target running time-frequency resource, so that user terminal be allow correctly to solve when carrying out blind Detecting PDCCH。
Referring to fig. 4, Fig. 4 is a kind of flow chart of communication means provided in an embodiment of the present invention, is applied to user terminal, such as Shown in Fig. 4, comprising the following steps:
If step 401, CORESET and the candidate running time-frequency resource of SSB are there are Chong Die, according to user terminal monitoring The target system information of PDCCH scheduling, determines target running time-frequency resource in the CORESET.
In the embodiment of the present invention, user terminal can receive the SSB corresponding with CORESET of network side equipment transmission, and According to the target system information of the PDCCH scheduling of user terminal monitoring, target running time-frequency resource is determined in CORESET.
Wherein, user terminal can pass through cyclic redundancy check (the Cyclic Redundancy for scrambling PDCCH Check, CRC) part radio network temporary identifier (Radio Network Tempory Identity, RNTI), judge The target system information of PDCCH scheduling；Alternatively, user terminal can also be judged by the type of the search space of PDCCH The target system information of PDCCH scheduling；Alternatively, user terminal can also pass through hybrid automatic repeat-request (Hybrid Automatic repeat request, HARQ) ID judges the target system information etc. of PDCCH scheduling.
