Mobile communication technology profoundly changes people's lives, but people are to the mobile communication technology of higher performance Pursuit never stop.In order to cope with, the following volatile mobile data flow increases, the equipment of mass mobile communication connects, no The disconnected all kinds of new business emerged in large numbers and application scenarios, the 5th generation (the fifth generation, 5G) mobile communication system are met the tendency of And it gives birth to.International Telecommunication Union (international telecommunication union, ITU) is the shifting of 5G and future Dynamic communication system defines three categories application scenarios: enhanced mobile broadband (enhanced mobile broadband, EMBB), highly reliable low time delay communication (ultra reliable and low latency communications, URLLC) with And magnanimity machine type communication (massive machine type communications, mMTC).

Typical eMBB business has: ultra high-definition video, augmented reality (augmented reality, AR), virtual reality (virtual reality, VR) etc., these business are mainly characterized by that transmitted data amount is big, transmission rate is very high.Typically URLLC business has: industry manufacture or the movement control of the wireless control in production procedure, pilotless automobile and UAV System and the haptic interactions class application such as remote repair, remote operation, these business are mainly characterized by requiring ultrahigh reliability, low Delay, transmitted data amount is less and has sudden.Typical mMTC business has: smart grid power distribution automation, wisdom city City etc., is mainly characterized by that networked devices enormous amount, transmitted data amount are smaller, the defeated time delay of data mutual transmission is insensitive, these mMTC Terminal needs to meet the demand of inexpensive and very long stand-by time.

Demand of the different business to mobile communication system is different, how preferably to support the data of a variety of different business simultaneously Transmission demand is technical problems to be solved needed for current 5G mobile communication system.For example, how to support URLLC business simultaneously It is exactly one of the discussion hot spot of current 5G mobile communication system with eMBB business.

The technical solution of the embodiment of the present application predominantly solves in 5G mobile communication system under URLLC application scenarios The problem that the transmission reliability of URLLC business is low is illustrated.The background context skill of URLLC business is briefly described below Art.

URLLC business is high to delay requirement, and in the case where not considering reliability, propagation delay time is required at 0.5 millisecond Within (millisecond, ms)；Under the premise of reaching 99.999% reliability, propagation delay time is required within 1ms.

In long term evolution (long term evolution, LTE) system, the smallest time scheduling unit is a 1ms The Transmission Time Interval (transmission time interval, TTI) of time span.In order to meet the biography of URLLC business Shorter time scheduling unit can be used in the data transmission of defeated delay requirement, radio open, for example, using mini time slot (mini-slot) or the time slot of bigger subcarrier spacing is as the smallest time scheduling unit.Wherein, a mini-slot Including one or more time-domain symbols, time-domain symbol here can be orthogonal frequency division multiplexing (orthogonal frequency Division multiplexing, OFDM) symbol or FDM symbol etc..It is 15 kHz for subcarrier spacing One time slot of (kilohertz, kHz), including 6 or 7 time-domain symbols, corresponding time span are 0.5ms；For sub- load Wave spacing is a time slot of 60kHz, and corresponding time span then shorten to 0.125ms.

In LTE system, each subframe is 14/12 OFDM symbol (respectively corresponding common CP and extension CP), wherein preceding 1 ~4 symbols are used for the transmission of control channel.CP, i.e. cyclic prefix, cyclic prefix are intersymbol dry for eliminating It disturbs.In order to realize that control channel search space is assigned in the flexible dispatching of terminal room, each terminal, terminal is needed according to pre- The fixed regular blind Detecting on control channel search space is either with or without one's own control channel (for example, physical down controls Channel (physical downlink control channel, PDCCH)).

Optionally, it is briefly introduced below for control channel search space.Specifically, search space is by several factors It constitutes:

1) polymerization grade (aggregation level): being divided into four grades, and corresponding 1/2/4/8 value indicates the end The number for the control channel unit (control channel element, CCE) that the PDCCH at end may occupy, wherein CCE is The basic unit of control channel physical resource, each CCE is by 9 resource unit groups (resource element group, REG) It constitutes, each REG includes 4 available resource units (resource element, RE).

2) candidate PDCCH (PDCCH candidate) number under every kind of polymerization grade: in order to increase dispatching flexibility, Blocking (blocking) is avoided, LTE provides that each terminal requires the multiple candidate PDCCH of blind Detecting under every kind of polymerization grade, Candidate PDCCH is the control channel that terminal may occupy.

3) the public and specific search space of terminal: public search space is mainly used for sending broadcast channel (broadcast Channel, BCH), the corresponding PDCCH of public informations such as paging channel (paging channel, PCH), due to being towards cell Interior all terminals, so polymerization grade only has 4 and 8, (polymerization grade length means that physical resource is more, and code rate is low, can allow small All terminals receive in area)；And the specific search space of terminal is mainly used for sending the corresponding PDCCH of the peculiar data of terminal, gathers Close the selection that grade has 1/2/4/8, the number of terminals that base station can be dispatched according to the down physical channel quality of terminal, current subframe Etc. Multiple factors terminal is scheduled to choose suitable polymerization grade and corresponding candidate PDCCH.It is worth noting that, public Search space and the specific search space of terminal can have overlapping altogether.Optionally, table 1 is the candidate PDCCH's of terminal monitoring The relationship of quantity and search space.Fig. 2 is the distribution schematic diagram of the search space of terminal 1 and terminal 2 in LTE.

Table 1

Optionally, in the 5th Generation Mobile Communication System, control channel resource collection is introduced for control channel resource The concept of (control resource set, CORESET), the i.e. corresponding one piece of running time-frequency resource of CORESET, a CORESET are For one group of terminal, the down control channel of this group of terminal can be sent on this CORESET；Each terminal can have multiple CORESET, each terminal have a search space (search space), the resource of the search space on a CORESET Resource less than or equal to CORESET.

Pass through in the 88th meeting of wireless access network as regulation: the multi-control channel resource collection of a terminal It can be overlapped over the frequency domain；A search space and single control channel resource set in 5th Generation Mobile Communication System Correlation is closed, the search space on different control channel resource collections is mutually indepedent；The maximum quantity of one terminal candidate's blind Detecting It is mutually indepedent with the quantity of control channel resource collection and the quantity of search space.Further, meeting has also passed through following It studies selective: first, for given control channel resource collection, the mapping ruler between CCE and REG is unique；The Two, for given search space, the mapping ruler between CCE and REG is unique.

Optionally, the relationship of CORESET, search space and candidate PDCCH is briefly described below.I.e.
