Description

Position determination method of paging opportunity and communication equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for determining a location of a paging opportunity and a communications device.

Background

In an existing Long Term Evolution (LTE) system, each Paging Opportunity (PO) occupies only one subframe, and the position of the PO appearing in a radio frame is relatively fixed, and in an FDD system, for example, the PO appears only in subframes with numbers of 0, 4, 5, and 9 in each radio frame. Since the high-frequency new air interface NR system needs to perform beam scanning operation, the length of one PO may exceed one subframe, so that the PO in subframe 9 in the current radio frame overlaps with the PO in subframe 0 in the next infinite frame (subframes 4 and 5 are similar), which directly causes the system to be unable to normally page most terminals belonging to the two POs, obviously, this situation cannot occur; on the other hand, a New air interface (NR) System newly introduces two possible position configuration relationships between a synchronization signal Block (SS Block, SSB), Remaining Minimum System Information (RMSI) and a PO, three modes of SSB and RMSI time-frequency resource positions, and a terminal monitors New technical requirements such as a Physical Downlink Control Channel (PDCCH) common search space principle, so that the paging mechanism using LTE cannot work at all because the position where the System PO appears is no longer determined by a Downlink subframe which only transmits Downlink data in uplink and Downlink subframe matching, and the PO, the SSB, and the RMSI of the NR System have a correlation mechanism, so that the position design of the NR paging PO is greatly limited by New technical conditions.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings.

Currently, the physical layer defines two time-frequency resource relationships between a Synchronization Signal Block (SSB), Remaining Minimum System Information (RMSI), and Paging Occasions (PO), where the first indicates that the time-frequency resource relationship between the SSB and the PO can be given by the configuration in the RMSI associated with the SSB; another provision is that the time-frequency resource relationship between SSB and PO is the same as the time-frequency resource relationship between SSB and associated RMSI. Although the physical layer gives the time-frequency resource correspondence between the two SSBs and POs, it does not give a description of the terminal paging listening behavior specified by the higher-layer system, that is, a description of which terminals should listen to paging at which PO in one paging cycle is lacked. The invention aims to solve the problem of how to monitor the position of the PO on the network side under the first time-frequency resource relationship between the SSB and the PO, and particularly provides a System Frame Number (SFN) index (index) and a Slot index (Slot index) of each terminal for monitoring a paging message.

In order to enable those skilled in the art to better understand the technical solution of the embodiment of the present invention, first, two possible position configuration relationships among SSBs, RMSIs, and POs, three modes of SSBs and RMSI time-frequency resource positions, and a Physical Downlink Control Channel (PDCCH) common search space principle, etc. that a terminal monitors, which are newly introduced into an NR system, are explained below.

(1) LTE paging background knowledge

User Equipment (UE, also called a terminal) uses Discontinuous Reception (DRX) to save energy consumption in an idle state, and a basic value range of a DRX cycle in an LTE system is {320ms, 640ms, 1280ms, and 2560ms }. The terminal is associated with a paging frame PF in each DRX period, the concept of the paging frame and the LTE radio frame is consistent, the association principle of the UE and the PF is shown in a PF calculation formula, one or more (at most four) POs exist in each PF, each PO represents the length of one radio subframe, the positions of the POs in the PFs are relatively fixed, only 1,2 or 4 POs can be determined to appear in one PF according to different system parameters, and the calculation principle of the specific PO is shown in the PO calculation formula, tables 1 and 2.

The terminal only monitors one PO in one DRX period, and the terminal keeps a dormant state at other moments, thereby achieving the purpose of saving power. The terminal uses a public Paging network temporary identity P-RNTI to demodulate (PDCCH) at the corresponding PO moment, demodulates a corresponding Physical Downlink Shared Channel (PDSCH) according to a time-frequency resource indicated in (DCI), transmits Paging Record (Paging Record) Information in the PDSCH, and determines whether to wake up by searching the ID Information (international mobile subscriber identity IMSI or S-TMSI) of the terminal in the Paging Record. The DRX cycle and some common parameters are provided by system information, and PF and PO are calculated by the following formula:

PF：SFN mod T＝(T div N)*(UE_ID mod N)；

PO：i_s＝floor(UE_ID/N)mod Ns；

the following are parameters used to calculate PF and i _ s:

t: indicating a DRX cycle, T being determined by the shortest DRX cycle, and if determined by higher layers, a default DRX cycle value is broadcasted in the system information; using a default value if the UE specific DRX value is not provided by higher layers;

-nB:4T,2T,T,T/2,T/4,T/8,T/16,T/32；

-N:min(T,nB)；

-Ns:max(1,nB/T)；

-UE_ID:IMSI mod 1024；

the IMSI is a sequence of digits consisting of the numbers 0 to 9, and the IMSI value in the above formula should be understood as a decimal value, i.e. the first digit represents the most significant digit.

For example: IMSI 12(digit 11, digit2 2);

in the calculation, the IMSI in the example is understood to be a decimal number "12", instead of "1x16+2 ═ 18".

The DRX parameters stored in the UE should be updated whenever the DRX parameters provided in the system message SI change. If the UE does not have an IMSI, for example, the UE performs emergency communication without a USIM, the UE should perform the above PF and PO calculation using a default UE ID, i.e., 0.

The LTE system includes FDD and TDD modes, and PO definition rules in different modes are shown in table 1 and table 2, where table 1 is a definition rule of PO in FDD mode and table 2 is a definition rule of PO in TDD mode.

2	0	5	N/A	N/A
					4	0	1	5	6

TABLE 2

In tables 1 and 2, N/a (not applicable) indicates no definition.

(2) Three modes of SSB and RMSI time-frequency resource location defined in NR systems.

Pattern 1(Pattern 1): as shown in fig. 1, the PDCCH and PDSCH corresponding to the SSB and the associated RMSI are separated in time, but the bandwidths used by the two are overlapped, the period of the RMSI in this mode is only 20ms, and the period value of the SSB may be any one of {5ms, 10ms, 20ms, 40ms, 80ms, and 160ms };

pattern 2(Pattern 2): as shown in fig. 2, the PDCCH corresponding to the SSB and the associated RMSI is separated in time, the PDSCH corresponding to the SSB and the associated RMSI is overlapped in time, but the PDCCH and the PDSCH corresponding to the SSB and the RMSI do not overlap in frequency domain, in this mode, the periods of the RMSI and the SSB are the same, and the period value may be any one of {5ms, 10ms, 20ms, 40ms, 80ms, and 160ms };

pattern 3(Pattern 3): as shown in fig. 3, the PDCCH and PDSCH corresponding to the SSB and the associated RMSI coincide in time, but the PDCCH and PDSCH corresponding to the SSB and RMSI do not overlap in frequency domain, and in this mode, the periods of the RMSI and the SSB are the same, and the period value may be any one of {5ms, 10ms, 20ms, 40ms, 80ms, and 160ms }.

(3) Two possible configuration relationships between SSBs, RMSIs and POs defined in the NR system.

Relation 1: as shown in fig. 4, the time-frequency resource relationship between the SSB and the PO may be given by the configuration in the RMSI associated with the SSB;

relation 2: as shown in fig. 5, the time-frequency resource relationship between SSB and PO is the same as the time-frequency resource relationship between SSB and associated RMSI.

(4) The NR system terminal listens to the common search space principle.

If the public search space of the PDCCH exists, the terminal determines which continuous resource blocks or continuous symbols are used as the PDCCH control resource public search space according to 4 bits in the RMSI-PDCCH-Config parameter and tables 3 to 12; the terminal determines the PDCCH monitoring time according to tables 13 to 17 by comparing 4 bits in the RMSI-PDCCH-Config parameter, which exists in a Master Information Block (Master Information Block) of the system. SFN_CAnd n_CControl resource SFN and slot indices, SFN and sub-carrier spacing based on control resource set_SSB,iAnd n_SSB,iSFN and slot indices derived based on subcarrier spacing of the control resource set, respectively, where the indices are SSB and SFN of i_SSB,iAnd n_SSB,iAre overlapping in time.

When the positional relationship of the SSB and the RMSI is mode 1, the terminalThe PDCCH is monitored in a common search space with a duration of two consecutive slots, where the corner of the first slot of the two slots is denoted as n₀SSB, n with angle i₀The calculation formula of (a) is as follows:

SFN corresponding to the time slot_CNumber satisfies the following condition:

where M and O are given by tables 13 and 14, μ ∈ {0,1,2,3} indicates the subcarrier spacing used for PDCCH reception defined in protocol TS 38.211. n is_CThe corresponding corner mark of the first symbol is also the corner mark of the first symbol given in tables 13 and 14.

When the position relationship between the SSB and the RMSI is mode 2 or mode 3, the terminal monitors the PDCCH only in one slot of the common search space, and the period of the common search space is consistent with the period of the SSB. When the angle of the SSB is denoted as i, n is determined by the contents of tables 15 to 17_CAnd SFN_CAnd (4) angle scale values.

An embodiment of the present invention provides a method for determining a location of a paging opportunity, which is applied to a terminal or a network side device, where the network side device may specifically be a base station, as shown in fig. 6, and the method for determining a location includes:

step 101: and determining the radio frame offset of the target synchronization signal block SSB period in the paging period relative to the reference radio frame according to the terminal identifier and the mode.

The mode is one of three modes of SSB and RMSI time-frequency resource location defined in the NR system. When the position determination method is applied to a terminal, the terminal can acquire the mode through a broadcast message of a base station.

The terminal identity is an IMSI or an identity allocated by the core network (S-TMSI or a newly defined terminal identity of 5G).

The target SSB period is one of at least one SSB period included in the paging period. The reference radio frame may be specifically SFN_DRX+SFN_DRX，SSB，SFN_DRX，SSBRepresenting SFN_DRXAnd is located at the SFN_DRXThe number of radio frames spaced between the radio frames where the first SSB is located later, SFN_DRXSFN, being the position of the start frame of the paging cycle_DRXAnd w is the corner mark of the first paging frame of the system.

Step 102: and determining the position of the paging opportunity PO in a target SSB period according to the position relation between the SSB and the residual minimum system information RMSI in the mode and the radio frame offset.

Specifically, the step 102 includes:

step 1021: and determining the target SSB period in at least one SSB period contained in a paging period according to a reference wireless frame and the wireless frame offset.

And adding the radio frame offset on the basis of a reference radio frame to obtain the position of the radio frame in the target SSB period.

The SSB is a periodic symbol unit used by the NR system to perform broadcasting and synchronization, and the period of the periodic symbol unit may be any one of {5ms, 10ms, 20ms, 40ms, 80ms, and 160ms }, and the basic value range of the DRX paging cycle is {320ms, 640ms, 1280ms, and 2560ms }, and from the values of the two periods, regardless of the value of the DRX paging cycle, there is one SS block symbol unit within a certain offset range of the starting position of each DRX cycle, so that by determining the starting position of each paging cycle, the position of the next SSB can be found every SSB cycle from the first SSB at the beginning of the paging cycle, that is, as long as the starting position of any paging cycle and the SSB cycle are determined, the position of any SSB in any paging cycle can be uniquely determined.

Step 1022: and determining the system frame number and the time slot angle index of the target RMSI associated with the target SSB in the target SSB period according to the position relation between the SSB and the RMSI in the mode.

Each SSB period includes a plurality of SSBs, each SSB is associated with one RMSI, and the target SSB is an SSB acquired by the terminal through beam scanning.

According to the above description, the position relationship between the SSB and the RMSI is defined in each mode, and therefore, the position relationship between the SSB and the RMSI in the mode and the position of the target SSB can obtain the system frame number and the timeslot corner index of the target RMSI.
