Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method for sending and receiving a paging message, a network device, and a terminal.
Background
In an LTE system, a Paging message may send a call request to a UE in an RRC _ IDLE state. Paging supports Discontinuous Reception (DRX), so that a UE in an RRC _ IDLE state only "wakes up" at a specific subframe (referred to as PO) of a specific frame (referred to as PF) within its Paging cycle to monitor a PDCCH (physical downlink control channel) scrambled using a P-RNTI (radio network temporary identity), and can remain in a "sleep" state at other times, thereby reducing power consumption and increasing battery life of the UE.
PO (Paging Occasion) is a subframe on which there may be a PDCCH scrambled using a P-RNTI (Paging radio network temporary identity) and indicating a Paging message.
When DRX is used, the UE only needs to detect 1 PO per DRX cycle, that is, only 1 subframe is available for transmitting Paging per Paging cycle for each UE. The DRX cycle (discontinuous reception cycle) is the same concept as the Paging cycle.
Pf (paging frame) is a radio frame, which may contain one or more POs. The PF is PF, namely the system frame for transmitting Paging, and satisfies the formula: SFN mod T ═ T div N (UE _ ID mod N), T is the discontinuous reception period of the terminal.
Looking up the following 2 tables with the index i _ s, we get the PO, which is the subframe in the PF used to send Paging. Where i _ s is obtained by the following equation: i _ s ═ floor (UE _ ID/N) mod Ns;
wherein floor (×) represents rounding, i.e. an integer representing quotient UE _ ID/N; UE _ ID represents the equivalent identity of the UE in connected state; n is the minimum value between T and a paging parameter nB pre-configured by the base station, wherein T represents the actual paging period of the UE in a connection state, Ns is the maximum value between 1 and nB/T, and mod represents modular operation.
FDD (frequency division duplex system):
| Ns | POwhen i_s＝0 | POwhen i_s＝1 | POwhen i_s＝2 | POwhen i_s＝3 |
| 1 | 9 | N/A | N/A | N/ |
| 2 | 4 | 9 | N/A | N/ |
| 4 | 0 | 4 | 5 | 9 |
TDD (time division duplex system) (all UL/DL configurations):
| Ns | POwhen i_s＝0 | POwhen i_s＝1 | POwhen i_s＝2 | POwhen i_s＝3 |
| 1 | 0 | N/A | N/A | N/A |
| 2 | 0 | 5 | N/A | N/A |
| 4 | 0 | 1 | 5 | 6 |
as can be seen from the above description: the T div N is equivalent to the system frame number contained in each part after one DRX cycle is equally divided into N parts; the UE _ ID mod N is equivalent to the 'UE _ ID mod N' (with the value range of 0-N-1) in N equal parts, and the PF is the first system frame in the N equal parts.
For a certain UE, the PF is the system frame used for transmitting Paging, and the PO is the subframe used for transmitting Paging in the PF.
Description of related parameters of PF/PO equation
It can be seen that, in the LTE system, for TDD, Paging interference occurs in 0/1/5/6 subframes, and for all TDD uplink and downlink configurations (as shown in the following table), the subframe 0/1/5/6 is a downlink subframe or a special subframe, and DwPTS in the special subframe can also be used for downlink transmission.
Uplink and downlink configuration
In the design of the 5G NR, it is considered that the Paging Occasion occurs only on the downlink transmission resource. The frame structure is configured semi-statically through high-level signaling, and includes a period, a fixed downlink transmission, a fixed uplink transmission, and other unknown resources, as shown in fig. 1 and 2. For semi-static paging frame structures of different periods, corresponding downlink time slots are different in position, for example, for a semi-static paging frame structure of a 10ms period, downlink time slots are 0, 1, 2, and 3; for a semi-static paging frame structure with a 5ms period, the downlink slots are at 0, 1, 5, 6. So should for different semi-static paging frame structure periods: 10ms, 5ms, 2ms, 1ms and 0.5ms, respectively, and the Paging occasion is designed.
The existing FDD and TDD frame structures cannot meet the characteristics of a flexible frame structure in 5G, so the existing design mode of Paging interference cannot be applied to 5G.

in this embodiment of the present invention, the step of determining the semi-static paging frame includes:
according to the formula: determining a frame number SFNs of a semi-static paging frame PFs in a semi-static paging period by using the SFNs (Ts div NS) × (UE _ ID mod NS); as shown in fig. 4 and 5.

In this embodiment of the present invention, the step of determining the paging opportunity PO in the semi-static paging frame includes: step 321, determining a first index i _ s of a paging opportunity PO;
specifically, according to the formula: determining a first index i _ s of a paging opportunity PO by floor (UE _ ID/NS) mod NSs;

Step 322, determining the paging opportunities PO according to the i _ s, the corresponding relationship between the number Nss of the paging opportunities PO contained in one semi-static paging frame PFs and the PO, the semi-static paging frame period, and the subcarrier interval.
Wherein step 322 comprises:
step 3221, determining a second index of the PO according to the i _ s, the corresponding relationship between the number Nss of the PO opportunities contained in one semi-static paging frame and the PO;
step 3222, determining a paging opportunity PO according to the second index, the semi-static paging frame period, and the subcarrier interval.
The correspondence between the i _ s and the number Nss of paging opportunities PO included in one semi-static paging frame PFs and the PO is shown in the following table, where K1, K2, K3, and K4 are second indexes:
| Nss | POwhen i_s＝0 | POwhen i_s＝1 | POwhen i_s＝2 | POwhen i_s＝3 |
| 1 | K1 | N/A | N/A | N/ |
| 2 | K1 | K2 | N/A | N/ |
| 4 | K1 | K2 | K3 | K4 |
in this embodiment of the present invention, the semi-static paging frame period includes: at least one semi-static paging frame period of different length, for example, the at least one semi-static paging frame period of different length includes: a first half static paging frame period (a 10ms half static paging frame period) having a cycle length of a first length, a second half static paging frame period (a 5ms half static paging frame period) having a cycle length of a second length, a third half static paging frame period (a 2ms half static paging frame period) having a cycle length of a third length, a fourth half static paging frame period (a 1ms half static paging frame period) having a cycle length of a fourth length, and a fifth half static paging frame period (a 0.5ms half static paging frame period) having a cycle length of a fifth length.
In this embodiment of the present invention, the first way to determine the paging opportunity PO is:
and in each semi-static paging frame period with different lengths, determining the paging opportunity PO in the downlink transmission resources corresponding to different subcarrier intervals according to the value of the second index.
Wherein the different subcarrier spacings comprise: a first subcarrier interval (subcarrier interval of 15K) in which the carrier interval is a first interval, a second subcarrier interval (subcarrier interval of 30K) in which the carrier interval is a second interval, and a third subcarrier interval (subcarrier interval of 60K) in which the carrier interval is a third interval;
each subcarrier interval has a corresponding number of downlink transmission resources in each semi-static paging frame period, and the downlink transmission resource is the minimum fixed downlink resource in a cell-level semi-static frame structure.
In a 5G system, each slot includes 14 symbols, and considering that the frequency is greater than 1GHz and less than 6GHz, when the subcarrier spacing is different, the number of slots included in different semi-static paging frame periods Ts is as shown in the following table:
further, looking up the table below, a second index of PO (values of K1, K2, K3, and K4) may be obtained, relating to different semi-static frame periods and subcarrier spacing.
Specifically, after the number of fixed downlink transmission resources in the semi-static frame period in the 5G NR design is determined (for example, in the 10ms period, when the subcarrier interval is 15K, the fixed 0 th timeslot in the 10 timeslots is a downlink timeslot, or the fixed 0 th and 1 st timeslots are downlink timeslots, or the fixed 0, 1, 2, and 3 th timeslots are downlink timeslots), when Nss is 4 (that is, when one PF frame includes 4 POs), the following table shows:
wherein, the values of K1, K2, K3 and K4 in the table are the subframe numbers of PO.
For example, when the paging parameter nB is T and Nss is 4, the above formula i _ s ═ floor (UE _ ID/NS) mod Nss is substituted with Nss ═ 4, and i _ s ═ 0, 1, 2, or 3;
taking the above table as an example, it can be seen from the table that when the subcarrier interval is 15K in a 10ms period, the PO used for transmitting the paging information in 10 slots is specifically 0, 1, 2, and 3 (i.e. the slot numbers are 0, 1, 2, and 3).
In this embodiment of the present invention, the second way of determining the paging opportunity PO is:
331, in at least one semi-static paging frame period with different lengths, a first number P1 of semi-static paging frame periods with the same length includes M1 POs, a second number P2 of semi-static paging frame periods includes M2 POs, and the first number P1 and the second number P2 of semi-static paging frame periods are the same and are any one of the semi-static paging frame periods with different lengths;
wherein the M1+ M2 POs are uniformly or non-uniformly distributed over the P1+ P2 semi-static paging frame periods;
ts is based on a system frame as a unit according to the formula: the length of a paging frame determined by the SFNs mod Ts ═ Ts div NS (UE _ ID mod NS) is 10 ms;
the number of PO included in each paging frame is Nss ═ max (1, nBs/Ts), M1+ M2 ═ Nss, P1+ P2 ═ 10/Ts ', and Ts' takes a value of a semi-static paging frame period.
Wherein, when M1+ M2 POs are evenly distributed in P1+ P2 semi-static paging frame periods:
p1 ═ mod (Nss,10/Ts '), M1 ═ ceil (Nss, 10/Ts') POs;
P2＝10/Ts’-mod(Nss,10/Ts’)，M2＝floor(Nss,10/Ts’)；
wherein ceil is rounding up.
Step 332, in the P1+ P2 semi-static paging frame period, in the downlink transmission resources corresponding to different subcarrier intervals, according to the value of the second index, determining the paging opportunities PO with M1+ M2 POs according to the indication of the bitmap.
For example, the PFs location is first determined, and PO is designed for different semi-static paging frame periods within each PFs, assuming that the semi-static paging frame period is Ts'.
(1) PO is uniformly distributed in all Ts', and the number of PO contained in each PFs is Nss ═ max (1, nBs/Ts). To ensure uniform distribution, the following rules are made:
there are mod (NSS,10/Ts ') Ts ' containing ceil (Ns,10/Ts ') POs, and the remaining 10/Ts ' -mod (Ns,10/Ts ') Ts ' containing floor (NSS,10/Ts ') POs.
Such as when Nss is 4,
(a) ts 'is 10ms, and 4 POs are included in Ts', as shown in fig. 6.
(b) Ts ' is 5ms, the first Ts ' contains 2 POs, and the second Ts ' also contains 2 POs, as shown in fig. 7.
(c) Ts ' is 2ms, and 4Ts ' contain 1 PO and 1 Ts ' does not contain PO.
(d) Ts ' is 1ms, and 4Ts ' contain 1 PO, and the remaining 6 Ts ' do not contain PO.
(e) Ts ' is 0.5ms, and 4Ts ' contain 1 PO, and the other 16 Ts ' do not contain PO.
Specifically, the POs is distributed in which Ts ', and is realized in a bitmap-based manner, for example, when Ts' is 2ms, and bitmap is 11110, it indicates that the first 4Ts 'respectively contain 1 PO, and the last 1 Ts' does not contain PO; ts ' is 1ms, and bitmap is 1111000000, indicating that the first 4Ts ' contain 1 PO and the last 6 Ts ' do not contain PO.
In addition, different Ts 'may correspond to different subcarrier spacings, so that PO corresponds to different slots, and in NR design, each slot includes 14 symbols, and considering that the frequency is greater than 1GHz and less than 6GHz, and then the subcarrier spacing is different, the number of slots included in different semi-static paging frame periods Ts' is as shown in the following table:
for simplification, assume that the bitmap mapping method is: the first mod (Ns,10/Ts ') Ts' contain ceil (Ns,10/Ts ') POs, and the remaining T/Ts-mod (Ns, 10/Ts') Ts 'contain floor (Ns, 10/Ts') POs.
