Fig. 1 is a kind of implementation process diagram of the monitoring method for PDCCH that one embodiment of the present of invention provides.Fig. 1 Method executed by terminal device.This method comprises:

Step 101, the incidence relation of at least one parameter of the SS based on PDCCH and at least one object, determines PDCCH Monitoring opportunity；

Wherein, at least one above-mentioned parameter includes: the period of SS, the offset of SS, the primary sign of SS, and SS is corresponding PDCCH monitors the duration T2 on initial time T1, the SS corresponding PDCCH monitoring opportunity on opportunity；At least one object includes: the time Window, Physical Random Access Channel opportunity (PRACH transmission occasion or PRACH occasion, RO), together It walks block (SS Block or SS/PBCH Block, SSB), channel state information reference signals (Channel State Information-Reference Signal, CSI-RS), user identifier (User Equipment Identification, UE ID)。

It should be understood that the incidence relation in the embodiment of the present invention can be specific formula, i.e. at least one ginseng of the SS of PDCCH It can be determined by the specific derivation of equation between several and at least one object, be also possible at least one parameter of the SS of PDCCH There are certain mapping relations at least one object.

When at least one parameter includes the corresponding PDCCH monitoring of initial time T1, SS on SS corresponding PDCCH monitoring opportunity The duration T2 on opportunity, at least one object include time window, and the value of T1, T2 and the initial position of time window and time window account for Used time is long, and there are when incidence relation, it is determined that the monitoring opportunity of PDCCH specifically can then determine SS corresponding PDCCH monitoring opportunity Within T1~T1+T2 time.

The embodiment of the present invention provides a kind of optional embodiment, and above-mentioned T1 can be with the initial position of time window, time There are mapping relations at least one of occupancy duration of window, that is to say, that T1 can be according to the initial position of time window, time At least one of occupancy duration of window derives determination；Above-mentioned T2 can also be accounted for the initial position of time window, time window With at least one of duration, there are mapping relations, that is to say, that T2 can also according to the initial position of time window, time window At least one of duration is occupied to derive determination.

For the efficiency for improving the monitoring opportunity for determining PDCCH, the embodiment of the present invention also provides a kind of optional embodiment, Above-mentioned T1 can be equal to the initial position of time window；T2 can be equal to the occupancy duration of time window.Specifically, due to PDCCH SS may include following six seed type: SS, paging of the SS of msg2PDCCH, SS, msg4PDCCH of the msg3PDCCH of re-transmission SS the and type3-PDCCH SS of the SS of PDCCH, OSI PDCCH, accordingly, it is determined that the monitoring opportunity of PDCCH may include with Under several situations:

Situation 1 can determine that T1 is corresponding after the last transmission msg1 if the SS of PDCCH is the SS of msg2PDCCH Random access response (Radom Access Response, RAR) time window initial position, T2 be RAR time window occupancy Duration；

Situation 2 can determine T1 if the SS of PDCCH is the SS of the SS or msg4PDCCH of the msg3PDCCH retransmitted After sending msg3 for the last time, start the time of timer, T2 is the duration of the timer, and wherein the timer such as can be with It is contention resolved timer (ra-Contention Resolution Timer)；

Situation 3 can determine that T1 is used for transmission for network side equipment if the SS of PDCCH is the SS of paging PDCCH The initial position of the time window of paging, when determining that T2 is occupancy of the network side equipment for the time window of transmission paging It is long；

Example 1, network side equipment can configure paging SS by RMSI.The time window of the Paging of UE1 is from slot T1 Start, a length of T2 of RAR window.In the paging SS configuration of RMSI configuration, the period P=1slot of SS deviates O=0slot, rises Beginning symbol S is symbol 0.That is, the SS of paging SS is defined as: since 2 time of continuous T slot T1, each There are a paging SS in slot, and the primary sign of SS is OFDM symbol 0.It is assumed that RACH CORESET time domain is long Degree is 2 symbols.

Assuming that network side equipment, which is broadcasted, carries paging SS configuration in the RMSI and the RMSI, then terminal device connects Receive the PDCCH that RMSI removes blind examination paging according to the paging SS of network side equipment configuration later.Terminal device it may be considered that Symbol 0-1 is for paging PDCCH monitoring opportunity and upper blind above on each slot in 2 time of continuous T that slot T1 starts Examine paging PDCCH.

Situation 4, if the SS of PDCCH is other systems information (Other System information, OSI) PDCCH's SS can then determine that T1 is the corresponding system information of OSI (system information, SI) corresponding SI time window (SI- Window initial position) determines that T2 is the occupancy duration of the corresponding system-information time window of the OSI, wherein the OSI is corresponding The occupancy duration of SI time window such as can be SI-Window Length；

Example 2, network side equipment can configure OSI SS by RMSI, and a slot is interior, and there are the starting characters of an OSI SS Number.The corresponding OSI SS of SI#N is since slot T1, the SI#N corresponding a length of 20ms of SI-window window, i.e. T2=20ms, SI# The period P=1slot of the corresponding OSI SS of N deviates O=0slot, and primary sign S is symbol 0, carries the OSI configured in RMSI In SS configuration, the corresponding OSI SS of SI#N is defined as: since 20ms continuous slot T1, in each slot, SI#N is corresponding The primary sign of OSI SS is OFDM symbol 0.It is assumed that network side equipment, which is broadcasted in the RMSI and the RMSI, carries SI#N Corresponding OSI SS configuration.

Terminal device determines after receiving RMSI carries SI#N corresponding OSI SS configuration, therefore, it is considered that can be according to This is configured to the PDCCH of SIB in blind examination SI#N.Terminal device thinks each slot in the continuous 20ms that slot T1 starts There are PDCCH to monitor opportunity, therefore terminal device can be opened in the continuous 20ms that slot T1 starts from the symbol 0 of each slot The PDCCH of SIB in beginning blind examination SI#N.

Example 3, it is assumed that network side equipment can configure OSI SS by RMSI, and a slot is interior, and there may be multiple OSI SS Primary sign, and these primary signs and SSB are relevant.Assuming that including M different SIB, such as SI#N in SI#N Include SIB#M0 and SIB#M1.Assuming that network side equipment sends up SIB#M0 in the side of SSB#X0~SSB#X1, in SSB#X2 The side of~SSB#X3 sends up SIB#M1.

And the corresponding OSI SS of SI#N is since slot T1, the SI#N corresponding a length of 20ms of SI-window window, i.e. T2= The period P=1slot of the corresponding OSI SS of 20ms, SI#N deviates O=0slot, and primary sign S is symbol 0 and 2, wherein 0 pair The starting point of SIB#M0PDCCH SS, the starting point of 2 corresponding SIB#M1PDCCH SS are answered, carrying is matched in the OSI SS that RMSI is configured In setting.It is assumed that network side equipment, which is broadcasted, carries the corresponding OSI SS configuration of SI#N in the RMSI and RMSI.

Terminal device finds to carry after receiving RMSI the corresponding OSI SS configuration of SI#N, therefore, it is considered that can be according to This is configured to the PDCCH of SIB in blind examination SI#N.Terminal device thinks each slot in the continuous 20ms that slot T1 starts There are PDCCH to monitor opportunity, has selected SSB#X0~SSB#X1 and has wanted that the terminal device for receiving SIB#M0 can be opened in slot T1 Begin continuous 20ms in, the PDCCH of blind examination SIB#M0 since the symbol 0 of each slot, selected SSB#X2~SSB#X3 and Want that the terminal device for receiving SIB#M1 can be in the continuous 20ms that slot T1 starts, the blind examination since the symbol 2 of each slot The PDCCH of SIB#M1.

Situation 5 can determine that T1 is to be used for transmission type3-PDCCH's if the SS of PDCCH is type3-PDCCH SS The initial position of time window determines that T2 is the occupancy duration for being used for transmission the time window of the type3-PDCCH, wherein type3- PDCCH can be INT-RNTI or SFI-RNTI or TPC-PUSCH-RNTI or TPC-PUCCH-RNTI or TPC-SRS- The scrambled PDCCH of RNTI or C-RNTI or CS-RNTI (s) or SP-CSI-RNTI.

It should be noted that the period P and offset O on the monitoring opportunity of the duration and T1, T2, PDCCH of above-mentioned time window Occupy one or more symbols (symbol), time slot (slot), millisecond (ms), subframe (subframe), frame (frame), and difference The unit of parameter may also be different, and may be relative time, duration, offset or absolute time, duration, partially It moves.For example, T1 may be relative time, such as T1 is which slot in each period (such as SI-window period)；T1 It is also likely to be absolute time, such as first subframe of the 10th frame.T2 may be opposite duration, such as T2 is RMSI SS prison Control twice of window length；T2 is also likely to be absolute time, such as 2 s lot.Offset may be opposite offset, for example, O be relative to N-th symbol after T1；T2 is also likely to be absolute drift, such as the 0th frame starting point N symbol of distance.It specifically can be according to different limits Condition processed determines that present invention one or more embodiments are not especially limited this.

Due in NR, RO is PRACH resource needed for being used for transmission preamble, RO both may with SSB corresponding relationship, May also with CSI-RS there are corresponding relationship for ease of description, in embodiments of the present invention, SSB and CSI-RS can be referred to as For the references object of RO.Therefore, the embodiment of the present invention also provides a kind of optional embodiment, when at least one object be RO, And SS be random access RA SS when, at least one parameter of SS and the incidence relation of RO include at least one of:

Incidence relation 1, a RO corresponds at least one parameter of a RA SS, for example, the corresponding RA of the same RO The parameter of SS can be identical, that is to say, that no matter a RO corresponds to how many SSB or CSI-RS, if user is sent out using the RO Random access is played, then in subsequent random access procedure, the parameter of the RACH SS of these users is the same；

Incidence relation 2, multiple RO correspond at least one parameter of the same RA SS, for example all RO can be corresponded to It is identical in the parameter of the same RA SS, the i.e. corresponding RA SS of these RO；

Example 4, it is assumed that network side equipment can configure RACH SS by RMSI.After terminal device the last time sends msg1, The RAR window of the corresponding msg1 is since slot T1, RAR window a length of 20 slot, i.e. T2=20slots.In RMSI configuration In RACH SS configuration, the period P=2slot of SS deviates O=1slot, and primary sign S is symbol 0.In the RACH of RMSI configuration In SS configuration, the SS of msg2PDCCH is defined as: since 20 slot continuous slot T1, exist in every 2 continuous slot One msg2PDCCH SS, and the slot where SS is second slot in two continuous slot.Include msg2PDCCH SS's In slot, the primary sign of msg2PDCCH SS is OFDM symbol 0.Assuming that RACH CORESET time domain length is 2 symbols.This In assume network side equipment broadcast carried in the RMSI and the RMSI RACH SS configuration.

Terminal device finds to carry RACH SS configuration after receiving RMSI, therefore, it is considered that matching according to network side equipment The RACH SS set removes the PDCCH of blind examination msg2.Terminal device can consider in continuous 20 slot that slot T1 starts, In The symbol 0-1 of slot T1+1, T1+3, T1+5, T1+7, T1+9 are that msg2PDCCH monitors opportunity, therefore terminal device can be In continuous 20 slot that slot T1 starts, the blind examination on slot T1+1, T1+3, T1+5, the symbol 0-1 of T1+7, T1+9 msg2PDCCH.The situation of above-mentioned incidence relation 1 and incidence relation 2 is referred to concrete scene described in example 4.

Incidence relation 3 is put upper frequency division multiplexing (Frequency-division multiplexing, FDM) at the same time The corresponding RA SS of multiple RO at least one parameter and RO in the position of frequency domain or number, there are mapping relations, for example, The period P on the monitoring opportunity of PDCCH is identical as O is deviated, and the value of primary sign S then can position based on RO in frequency domain or volume It number determines.

Example 5, in a PRACH configuration period, for the corresponding RACH SS of RO that a time point upper frequency domain number is X Beginning symbol S is a function relevant with X, it is assumed that the symbolic number that S=(X mod N) * CORESET time domain occupies.Wherein, N is The RO number of one time point upper FDM, S is no more than (symbolic number+1 that 13-CORESET time domain occupies).Wherein mod is complementation Function.

Or, it may also assume that the symbolic number that S=(X mod Y) * CORESET time domain occupies, O=ceil (X/Y), O is not It can exceed that P, S is no more than (symbolic number+1 that 13-CORESET time domain occupies).Here make will be on a time point for the value of Y The RACH SS of different RO is distributed in multiple slot, for example Y=4 can indicate to be up to 4 RACH SS in a slot, and one If there is the RO of 8 FDM on a time point, then in a RACH SS period, the corresponding RACH SS of these RO is dispersed in 2 not On same continuous slot.Such as Y=2, it can indicate to be up to 2 RACH SS in a slot, if a time point is upper There is the RO of 8 FDM, then the corresponding RACH SS of these RO can be dispersed on 4 different continuous slot.Wherein ceil is Integral function is sought upwards.

Optionally, above-mentioned incidence relation 2 may include following one:

Incidence relation 4, in different time points, time division multiplexing mould (the Time Division of same frequency position Multiplexing, TDM) multiple RO correspond to the same RA SS at least one parameter, such case can also be with reference example Concrete scene described in 4；Or

Incidence relation 5, if references object corresponds to multiple RO, multiple RO pairs corresponding to a references object It should include type at least one parameter of the same RA SS, references object include SSB and CSI-RS, for example, with the same ginseng A public RACH SS can be defined by examining the corresponding all RO of object.

Optionally, above-mentioned incidence relation 5 can also include: incidence relation 6, institute corresponding to multiple continuous references object There is RO to correspond at least one parameter of the same RA SS, for example, a references object corresponds to multiple RO, then continuous N refers to The corresponding RA SS of the associated all RO of object is identical, and wherein M is positive integer.

Example 6, it is assumed that the corresponding X RO of a references object (SSB or CSI-RS), a total of N number of references object.Reference pair As the primary sign S of the corresponding RACH SS of the corresponding RO of #n is a function relevant with n, it is assumed that S=n*CORESET time domain The symbolic number occupied, S is no more than (symbolic number+1 that 13-CORESET time domain occupies).Or, it may also assume that, continuous N The corresponding RACH SS of the corresponding all RO of references object is identical, such as continuous N references object: references object #n, reference pair As #n+1, references object #n+2 ... ..., references object #n+M-1 have corresponding RO, then this M references object is RO pairs corresponding The RACH SS primary sign answered is the symbolic number that S=(n mod M) * CORESET time domain occupies, and actually continuous N is joined at this time The RACH SS for examining object is identical, and the primary sign S of PDCCH is no more than (symbolic number+1 that 13-CORESET time domain occupies).

It should be noted that in the embodiment of the present invention at least one object be RO, and the SS of PDCCH be RA SS when, object Then there is incidence relation described above between at least one parameter of RO and RA SS.

Optionally, the parameter letter for including in the SS configuration information that the embodiment of the present invention can both have been sent based on network side equipment It ceases to directly determine the monitoring opportunity of PDCCH, the parameter information that can also include in the SS configuration information of acquisition and above-mentioned pass The monitoring opportunity of PDCCH is determined on the basis of connection relationship the two, and hence it is also possible to SS configuration information is obtained, SS configuration Information may include monitoring period on opportunity of PDCCH, offset, primary sign, the initial time T1 on PDCCH monitoring opportunity and At least one of the duration T2 on PDCCH monitoring opportunity.

Optionally, when the period on the monitoring opportunity of the PDCCH in SS configuration information, offset, primary sign, PDCCH monitoring At least one of the duration T2 on initial time T1 and PDCCH the monitoring opportunity of machine is set based on protocol conventions or by network side Standby configuration.When the period on the monitoring opportunity of the PDCCH in SS configuration information, offset, primary sign, PDCCH monitor opportunity At least one of the duration T2 on initial time T1 and PDCCH monitoring opportunity is should to be then based on agreement about based on protocol conventions Fixed SS configuration information can be determining based on RMSI SS configuration.

When SS configuration information is based on protocol conventions, there is no need to network side equipments additionally to add when issuing high-level signaling Add comprising the SS configuration information, so as to save the bit number of high-level signaling, and then save signaling overheads, increases covering model It encloses.

Specifically, may include following several situations:

(1) monitoring period on opportunity of PDCCH, offset, primary sign, the initial time T1 on PDCCH monitoring opportunity and The duration T2 on PDCCH monitoring opportunity is entirely protocol conventions, for example, PDCCH monitoring opportunity period P=1slot, partially Symbol 0, the initial time T1=2slot and PDCCH on PDCCH monitoring opportunity moved in O=0, primary sign S instruction slot is monitored The duration T2=1slot on opportunity；

(2) monitoring period on opportunity of PDCCH, offset, primary sign, the initial time T1 on PDCCH monitoring opportunity and The duration T2 that PDCCH monitors opportunity is entirely based on RMSI SS configuration determination, for example, the period on the monitoring opportunity of PDCCH P is equal to the RMSI SS period, and offset is equal to RMSI SS and deviates, and primary sign S is from the derivation of RMSI SS primary sign, PDCCH The initial time T1 on monitoring opportunity is equal to the initial time of RMSI SS, and the duration T2 that PDCCH monitors opportunity is equal to RMSI SS week N/mono- of phase or integral multiple, wherein N is positive integer；

(3) monitoring period on opportunity of PDCCH, offset, primary sign, the initial time T1 on PDCCH monitoring opportunity and Partial parameters in the duration T2 on PDCCH monitoring opportunity are protocol conventions, and partial parameters are all based on RMSI SS configuration and determine , for example, PDCCH monitoring opportunity period P=1slot, offset O=0, primary sign S instruction slot in symbol 0, PDCCH monitors the initial time T1=2slot on opportunity, and primary sign S is from the derivation of RMSI SS primary sign, PDCCH monitoring The initial time T1 on opportunity is equal to the initial time of RMSI SS, and the duration T2 that PDCCH monitors opportunity is equal to the N in RMSI SS period / mono- or integral multiple, wherein N is positive integer.

Example 7, network side equipment can configure RACH SS by RMSI.It is corresponding after terminal device the last time sends msg1 The RAR window of the msg1 is since slot T1, RAR window a length of 10 slot, i.e. T2=10slots.Assuming that each slot exists The primary sign of msg2PDCCH SS is OFDM symbol 0, RACH CORESET time domain in one msg2PDCCH SS, each slot Length is 2 symbols.It is assumed that network side equipment is broadcasted in the RMSI and the RMSI without carrying RACH SS configuration.

Terminal device finds that terminal device is it may be considered that PDCCH without carrying RACH SS configuration after receiving RMSI Monitoring opportunity period=1slot, deviate O=0slot, primary sign S=0.I.e. terminal device can consider from slot T1 In continuous 10 slot started, the symbol 0-1 of each slot is that msg2PDCCH monitors opportunity, therefore terminal device can be In continuous 10 slot that slot T1 starts, blind examination msg2PDCCH on the symbol 0-1 of each slot.

Optionally, when the period on the monitoring opportunity of the PDCCH in SS configuration information, offset, primary sign, PDCCH monitoring Opportunity initial time T1 and PDCCH monitoring opportunity at least one of duration T2 be that network side equipment configures, then these It can be transmitted by RMSI, RRC or OSI by the SS configuration information that network side equipment configures.
