Specific embodiment
The embodiment of the present application provides channel transmission method and device, computer storage medium, and use is so that terminal can be with
It determines existing search space type in control resource collection, and is realized based on determining search space type provided in control in turn
Transmission in the set of source.
In LTE system, terminal needs the public search space in each non-DRX subframe (subframe)
On the search space (UE-specific Search Space, USS) of (Common Search Space, CSS) and user equipment
Detection receives down control channel.In the following 5G system, the control resource collection for being used for transmission down control channel may be only
There are USS, perhaps only exist CSS or exist simultaneously CSS and USS.And the down control channel that is transmitted in CSS and
The DMRS pilot configuration used when the down control channel demodulation transmitted in USS is different, and the beam direction used is also different,
Such as the relevant QCL of DMRS is different.Technical solution provided by the embodiments of the present application gives and how to notify in terminal CORESET
Existing search space type, and, how terminal detects reception down control channel.

CSS, and/or, organize public search space G-CSS.
That is, terminal receives the explicit signaling that base station is sent in the embodiment of the present application, determine in one or more
Existing search space type in CORESET, and according to base station notice or predefined sequence, inspection in described search space
It surveys and receives different types of down control channel.
For example, terminal receives wireless heterogeneous networks (Radio Resource Control, RRC) signaling that base station is sent
(signaling), existing search space type in CORESET is determined.
Specifically, base station notify terminal CORESET there are USS or CSS or G-CSS by RRC signaling or
Person exists simultaneously any combination in three.
Alternatively, such as base station is notified by remaining system information (Remaining system information, RMSI)
Terminal, the CORESET of the PDCCH of transmitting and scheduling RMSI is interior to whether there is USS.
When, there are when USS, the USS is by the predefined one group of object of agreement in the CORESET of the PDCCH of transmitting and scheduling RMSI
Transmitted over resources is managed, the physical resource is for example including N number of logic CCE in CORESET.The PDCCH for including in USS
Candidate number and type, can be predefined by agreement.Such as: polymerization grade (Aggregation level, AL)
=1 PDCCH candidate has M1, and the PDCCH candidate of AL=2 has M2.Wherein, M1 and M2 is positive integer.
Alternatively, when, there are when USS, the USS is in one group notified by base station in the CORESET of the PDCCH of transmission RMSI
Transmitted on physical resource, for example, by RMSI perhaps RAR notice form the USS logic CCE number initial position or
Deviant, or specific CCE index (index).Further, the AL of the PDCCH candidate transmitted in USS with
And quantity to terminal or can also be predefined by base station explicit notification.
Alternatively, such as base station by random access response in random access procedure (Random Access Response,
RAR), it whether there is USS in the CORESET of the PDCCH of notice terminal transmission scheduling RMSI.
When, there are when USS, the USS is by the predefined PDCCH of agreement in the CORESET of the PDCCH of transmitting and scheduling RMSI
Candidate composition.
Alternatively, when there are the PDCCH that when USS, the USS includes in the CORESET of the PDCCH of transmission RMSI
Candidate is notified by base station, such as the specific PDCCH candidate of the USS is made up of RAR notice.
To sum up, optionally, when described search sky existing in the control resource collection of PDCCH for being used for transmission scheduling RMSI
Between type when including USS, the USS is transmitted on the physical resource that predefined or network side notifies.
Optionally, according to existing search space type in the control resource collection, transmission is carried out, it is specific to wrap
It includes:
According to predefined detection reception sequence or the detection reception sequence of network side notice, in the control resource set
Detection receives different types of down control channel in different search spaces in conjunction.
Optionally, the different types of down control channel, including one of following classes or combined physical down control
Channel PDCCH processed:

When, there are when a plurality of types of down control channels, terminal is according to predefined sequence detection in a CORESET
Down control channel is received, such as detection receives P1 first, secondly detection receives P2, and then detection receives P3, and finally detection connects
Receive P4.
There may be the part in P1~P4 in one CORESET, it also may include other down control channels, herein
Without limitation.
In addition, it is necessary to explanation, predefined detection reception sequence is not limited in sequence as above, however not excluded that other inspections
Reception sequence is surveyed, can be decided according to the actual requirements.
Alternatively, when, there are when a plurality of types of down control channels, terminal notifies suitable according to base station in a CORESET
Sequence detects different types of down control channel.
Base station can perhaps RMSI or RAR, notice terminal detection receive down control channel by high-level signaling
Sequentially.
For example, co-existing in the different down control channel type of N kind in system, such as N=4 is taken, then terminal can pass through
N*ceil (log2 (N)) bit instruction detection reception sequence, by taking detection reception sequence as above as an example, referring to following table one, this refers to
Show that domain is 00 01 10 11.

Road.By taking P1, P2, P3, P4 as an example, it can determine that detection receives the suitable of down control channel by one of the following two kinds mode
Sequence.
Base station indicates detection ordering by 8bit information, and highest order indicates the down control channel type of highest priority,
Lowest order indicates the minimum down control channel type of priority.Such as 00 indicate P1,01 represents P2, and 10 represent P3, and 11 represent
P4.If the detection reception sequence of base station notice is P1P2P3P4, the 8bit information is 00011011.
Base station indicates the combination of a detection reception sequence by way of instruction form index.For example, making a reservation in system
Detection reception sequence in justice 4, shown in table four specific as follows.Base station indicates that information indicates four kinds of down control channel inspections by 2bit

search space).Base station can notify that there are the exclusive search space (UE of UE in the CORESET by RMSI or RAR
Specific search space, UESS).Such as indicate that information indicates whether UESS by 1bit.
The PDCCH that UESS includes in the CORESET (RMSI-CORESET) for being used for transmission the PDCCH of scheduling RMSI
The number of candidate and position are predefined by agreement.For example, agreement provides the USS in RMSI-CORESET, include
The AL of PDCCH candidate is respectively 4 and 8, and the candidate number under each AL is respectively 4 and 4.And initial position
Since first logic CCE in the CORESET.
Alternatively, the number for the PDCCH candidate that UESS includes in RMSI-CORESET and position are wide by physics
Broadcast channel (PhysicalBroadcastingChannel, PBCH) or RAR notice.Such as PBCH or RAR notice terminal exists
The initial position for the PDCCH candidate that UESS in RMSI-CORESET includes, candidate number for including etc..
When in the RMSI-CORESET including a variety of down control channel types, terminal is according to institute in such as embodiment 1
The method stated determines that detection receives the sequence of down control channel.
Embodiment 4:
Such as embodiment 1-3, after terminal determines the blind examination sequence of down control channel, according to determining blind examination sequence detection
Receive down control channel.After terminal detection receives down control channel, subsequent other types downlink control letter is no longer carried out
The detection in road receives.
