Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc..

The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

The network device may be a device for communicating with a mobile device, and the network device may be an Access Point (AP) in a WLAN, a Base Station (BTS) in GSM or CDMA, a Base Station (NodeB, NB) in WCDMA, an evolved Node B (eNB, eNodeB) in LTE, a relay Station or an Access Point, or a network device or a Base Station (gNB) in a vehicle-mounted device, a wearable device, and an NR network, or a network device in a PLMN network for future evolution.

In this embodiment of the present application, a network device provides a service for a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a Small cell (Small cell), where the Small cell may include: urban cells (Metro cells), micro cells (Micro cells), pico cells (Pico cells), femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission service.

Before introducing the technical solution of the present application, a paging mechanism and a paging DRX mechanism of NR are introduced as follows:

the Paging main function is to enable the network device to page the terminal device through a Paging message (Paging message) in an RRC IDLE or RRC INACTIVE state of the terminal device, or notify the terminal device of a system message change or tsunami/public warning information (which is applicable to all Radio Resource Control (RRC) states of the terminal device, including a connection state) through a short message (short message).

The Paging Channel includes a Physical Downlink Control Channel (PDCCH) scrambled by a Paging Radio Network Temporary Identifier (P-RNTI), and a Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH. Paging messages are transmitted in the PDSCH and short messages are transmitted in the PDCCH.

For the terminal device in the RRC _ IDLE state or the RRC _ INACTIVE state, since there is no other data communication between the terminal device and the network device, in order to save power for the terminal device, the terminal device may employ a paging DRX mechanism. Under the Paging DRX mechanism, the terminal device only needs to monitor Paging during one PO in each DRX cycle. One PO includes at least one PDCCH monitoring occasion (PDCCH monitoring occasion), and one PO may consist of multiple slots. For a Paging Frame (PF), which is a radio Frame (fixed 10 ms), the radio Frame may contain POs or the start positions of the POs.

The DRX cycle is determined by a common cycle in system broadcast and a terminal-specific cycle configured in higher layer signaling, such as Non-access stratum (NAS) signaling, and the terminal device takes the minimum cycle of the two as the DRX cycle. From the network perspective, a DRX cycle may include a plurality of POs, where the location where the terminal device monitors the POs is related to an Identity (ID) of the terminal device, and the PF and the PO of a specific terminal device in a DRX cycle are determined as follows:

the System Frame Number (SFN) of the PF is determined by equation (1):

(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N) (1)

the number (i _ s) of PO within one PF is determined by equation (2):

i_s＝floor(UE_ID/N)mod Ns (2)

the parameters for equations (1) and (2) are explained as follows:

t: the terminal device receives the DRX cycle of the page. The network device broadcasts 1 default DRX period, and if the RRC/high layer configures the terminal device with the DRX period special for the terminal device, the minimum DRX period in the DRX period broadcasted by the network device and the DRX period special for the terminal device configured by the RRC/high layer is taken as the DRX period of the terminal device. And if the RRC/high layer does not configure the terminal equipment with the DRX period specific to the terminal equipment, taking the DRX period broadcasted by the network equipment as the DRX period of the terminal equipment.

N: the number of PFs included in one DRX cycle.

Ns: the number of POs contained in one PF.

PF _ offset: for determining a time domain offset of the PF.

UE_ID：5G-S-TMSI mod 1024。

Where mod represents the remainder, and floor () is a floor function.

In the present application, the DRX Cycle may also be referred to as a Paging Cycle (Paging Cycle) or a Paging DRX Cycle (Paging DRX Cycle).

After the terminal device determines the numbers of the PF and the PO and the number of the PDCCH monitoring occasions in the PO, it only needs to determine the starting position of the first PDCCH monitoring occasion of the PO by the relevant configuration parameters, and the starting position may be configured by a high-level signaling or obtained based on the number of the PO, and the terminal device blindly detects paging according to the determined PO.

The blind detection paging comprises the following steps: and blind detection of the PDCCH and the PDSCH scheduled by the PDCCH. For a terminal device in the RRC _ IDLE state or the RRC _ INACTIVE state, the terminal device needs to perform synchronization before blind detection of the PDCCH, and for a terminal device with better channel quality, such as a terminal device with a higher Signal to Interference plus Noise Ratio (SINR), less Synchronization Signal (SS) bursts (bursts) may be needed to complete synchronization, and for a terminal device with poorer channel quality, such as a terminal device with a lower SINR, more SS bursts may be needed to complete synchronization.

In the third generation partnership project (3 GPP) standard discussion, the idea of transmitting PEI before PO is proposed for power saving (power saving), wherein the PEI transmission time may be located close to SS burst, and PEI signals are received through synchronization of SS burst. However, when there are a plurality of terminal devices whose POs correspond to PEI, how to determine the monitoring time of PEI corresponding to the PO of each terminal device is not disclosed at present, that is, how to determine the correspondence between PO and PEI is not disclosed at present.

In order to solve the problem of how to determine the monitoring time of the PEI corresponding to the PO of each terminal device, the monitoring time of the PEI is determined according to the minimum time offset between the PEI configured by the network and the reference time (which is related to the PF and/or PO of the terminal device), and the number of synchronization Signal Measurement Timing Configurations (SMTCs) between the PEI and the reference time at intervals.

The technical solution of the present application is detailed below by specific examples.

Fig. 2 is an interaction flowchart of a wireless communication method according to an embodiment of the present application, where the method includes the following steps:

step S210: and the first terminal equipment receives the minimum time offset between the first PEI and the reference time and the number of SMTCs required by the first PEI and the reference time.

Step S220: and the first terminal equipment determines the monitoring opportunity of the first PEI according to the minimum time offset and the number of the SMTCs.

Optionally, the minimum time offset between the first PEI and the reference time, and the number of SMTCs that need to be separated between the first PEI and the reference time are configured by the network device to the first terminal device through dedicated signaling or broadcast message.

Alternatively, the dedicated signaling may be Downlink Control Information (DCI), RRC signaling, or Media Access Control Element (MAC CE) signaling.

Optionally, the network device may further configure the paging related information, the SMTC related information, and other PEI related information except for the minimum time offset and the number of SMTCs for the first terminal device.

Optionally, the paging related information includes: a Paging search space, a default Paging Cycle (default Paging Cycle), the number N Of PFs included in one Paging Cycle, the number Ns Of POs included in one PF, and a first PDCCH-Monitoring Occasion position (first PDCCH-Monitoring occupancy Of PO) Of each PO in one PF. It should be noted that after the terminal device obtains the paging related information, the PF and PO positions of the first terminal device and the position of the PDCCH monitoring opportunity in each PO may be determined according to the paging related information.

The SMTC related information is configured for a frequency point where a serving cell of the first terminal device is located, and includes an SMTC cycle, a time offset in one cycle, and an SMTC window duration, where the time offset in one cycle refers to a time offset between a start time of the SMTC window in one cycle and a start time of the cycle. It should be noted that after the terminal device acquires the SMTC-related information, the distribution of SMTC may be determined according to the SMTC-related information.

PEI related information, which is configured by a network device for all terminal devices in a cell in a public manner, may be carried in a system message, where the PEI related information includes, in addition to the minimum time offset and the number of SMTCs, the PEI related information:

1 PEI search space.

Optionally, the minimum time offset is configured according to a minimum processing power of the first terminal device for the first PEI.

It should be noted that after the terminal device acquires the information related to the PEI, the monitoring time of the PEI may be determined according to the information related to the PEI.

In the examples of the present application, the role of the first PEI includes, but is not limited to, the following two cases:

case 1: the first PEI is used for indicating whether the terminal equipment on the at least one PF needs to monitor the PDCCH scrambled by the P-RNTI on the corresponding PO in the at least one PF.

As described above, in one paging cycle, a terminal device only needs to listen to paging during one PO in the paging cycle, and therefore, a terminal device on at least one PF is understood as at least one terminal device on at least one PF. The first PEI is actually used to indicate whether at least one terminal device on at least one PF needs to listen for a P-RNTI scrambled PDCCH on the respective corresponding PO.

Case 2: the first PEI is used for indicating whether the terminal equipment on the at least one PO needs to monitor the PDCCH scrambled by the P-RNTI on the corresponding PO in the at least one PO.

Similarly, as described above, in one paging cycle, a terminal device only needs to listen to paging during one PO in the paging cycle, and thus, a terminal device on at least one PO is understood as at least one terminal device on at least one PO. The first PEI is actually used to indicate whether at least one terminal device on at least one PO needs to listen for a P-RNTI scrambled PDCCH on the respective corresponding PO.

The effect of PEI is illustrated by the following specific examples:

example 1: fig. 3 is a schematic diagram of a relationship between PEI and PO according to an embodiment of the present application, and fig. 4 is a schematic diagram of a relationship between PEI and PO according to an embodiment of the present application, where, as shown in fig. 3 and fig. 4, the PEI is used to instruct a terminal device on a PF to monitor a PDCCH scrambled by a P-RNTI on a corresponding PO in the PF. The PF comprises PO1 and PO2, PO1 is PO of UE1, PO2 is PO of UE2, therefore, PEI is used for indicating UE1 not to monitor PDCCH scrambled by P-RNTI on PO1 and indicating UE2 not to monitor PDCCH scrambled by P-RNTI on PO 2.

Example 2: fig. 5 is a schematic relationship diagram of another PEI and PO according to an embodiment of the application, where as shown in fig. 5, PEI1 is used to indicate that UE1 does not need to monitor a PDCCH scrambled by P-RNTI on PO1, and PEI2 is used to indicate that UE2 needs to monitor the PDCCH scrambled by P-RNTI on PO 2.

In the embodiment of the present application, the reference time is related to the PF and/or PO of the first terminal device. The definition of the reference time includes, but is not limited to, the following three cases:

case 1: the reference time is a start time of the PF of the first terminal device.

Case 2: the reference time is a starting time of a first PDCCH monitoring occasion in a first PO within the PF of the first terminal device.

Case 3: the reference time is a start time of a first PDCCH monitoring occasion in the PO of the first terminal device.

The reference time is described below by specific examples:

example 1: according to case 1 with reference to the reference time, as shown in fig. 3, the reference time is the starting time of PF shown in fig. 3 for both UE1 and UE 2.

Example 2: according to case 2 of the reference time, as shown in fig. 4, for UE1 and UE2, the reference time is the starting time of the first PDCCH monitoring occasion of the first PO (i.e. PO 1) in the PF shown in fig. 4.

Example 3: according to the case 3 of the reference time, as shown in fig. 5, for the UE1, the reference time is the starting time of the first PDCCH monitoring occasion of PO1 in the PF shown in fig. 5, and for the UE2, the reference time is the starting time of the first PDCCH monitoring occasion of PO2 in the PF shown in fig. 5.

The above explanation explains the case of the first PEI, the reference time, and the minimum time offset and the number of SMTCs, and based on this, how to determine the listening timing of the first PEI will be explained in detail below:

optionally, the first terminal device determines that the M +1 th SMTC located before the reference time and having a time interval with the reference time not less than the minimum time offset is the SMTC corresponding to the first PEI, where M is equal to the number of SMTCs, and M is a positive integer. And the first terminal equipment determines the monitoring time of the first PEI according to the SMTC corresponding to the first PEI.

In the embodiment of the present application, the listening timing of the first PEI may be determined by the following methods, but is not limited thereto:

the first alternative is as follows: the monitoring time of the first PEI is the PEI monitoring time within a period of time with the starting time of the SMTC corresponding to the first PEI as the starting time.

The second option is: the monitoring time of the first PEI is the PEI monitoring time within a period of time with the termination time of the SMTC corresponding to the first PEI as the starting time.

The optional mode three: the monitoring time of the first PEI is S continuous PEI monitoring time after the start time of the SMTC corresponding to the first PEI, and S is the number of Synchronization Signal Blocks (SSBs) transmitted by the network device.

The optional mode four: the monitoring time of the first PEI is S continuous PEI monitoring time after the termination time of the SMTC corresponding to the first PEI, and S is the number of SSBs sent by the network equipment.

It should be noted that the duration is configured by the network device, for example: the network device configures the duration to the first terminal device through DCI, RRC signaling, MAC CE signaling, or a broadcast message.

Optionally, the PEI sent on S consecutive PEI monitoring occasions are the same, and the PEI sent on S consecutive PEI monitoring occasions correspond to different SSBs.

Exemplarily, the above alternative two will be described below with reference to fig. 3, fig. 4 and fig. 5, respectively:

as shown in fig. 3, the number of SMTCs configured by the network device =3, for both UE1 and UE2, the reference time is the start time of the PF shown in fig. 3, and then, in combination with the minimum time offset shown in fig. 3, the PEI monitoring opportunity within a duration in which the termination time of the SMTC corresponding to the PEI (i.e., the 4 th SMTC in the order from right to left) is the start time can be obtained.

As shown in fig. 4, the number of SMTCs configured by the network device =3, for both UE1 and UE2, the reference time is the start time of the first PDCCH monitoring occasion of the first PO in the PF shown in fig. 4, and then, in combination with the minimum time offset shown in fig. 4, the monitoring occasion of the PEI can be obtained as a PEI monitoring occasion within a duration in which the termination time of the SMTC (i.e., the 4 th SMTC in the order from right to left) corresponding to the PEI is the start time.

As shown in fig. 5, the number of SMTCs configured for the UE1 by the network device =3, for the UE1, the reference time is the start time of the first PDCCH monitoring occasion of the PO1 in the PF shown in fig. 5, and then, in combination with the minimum time offset shown in fig. 5, the monitoring occasion of the PEI1 can be obtained as a PEI monitoring occasion within a duration in which the end time of the SMTC (i.e., the 4 th SMTC in the order from right to left) corresponding to the PEI1 is the start time. The number of SMTCs configured by the network device for the UE2 =2, for the UE2, the reference time is the start time of the first PDCCH monitoring occasion of PO2 in the PF shown in fig. 5, and then, in combination with the minimum time offset shown in fig. 5, the PEI monitoring occasion within a duration in which the monitoring occasion of the PEI2 is the end time of the SMTC corresponding to the PEI2 (i.e., the 3 rd SMTC in the order from right to left) as the start time can be obtained.

Further, after the first terminal device obtains the monitoring opportunity of the first PEI, the first terminal device may monitor the first PEI at the monitoring opportunity of the first PEI. However, it is not certain whether the first terminal device can monitor the first PEI, and based on this, the first terminal device may decide whether to monitor the P-RNTI scrambled PDCCH on the corresponding PO according to whether the first PEI is monitored. The method comprises the following specific steps:

and if the first terminal equipment monitors the first PEI, the first terminal equipment determines whether to monitor the PDCCH scrambled by the P-RNTI on the PO of the PF of the first terminal equipment according to the indication of the first PEI. As shown in fig. 3, 4 and 5, UE1 and UE2 both monitor PEI, based on which UE1 and UE2 can determine whether to monitor the P-RNTI scrambled PDCCH on the PO of the PF of the first terminal device according to the corresponding PEI indication.

If the first terminal device does not monitor the first PEI, the first terminal device monitors the PDCCH scrambled by the P-RNTI on the PO of the PF of the first terminal device, or determines whether to monitor the PDCCH scrambled by the P-RNTI on the PO of the PF of the first terminal device according to the indication of the network device. The network device may indicate, through DCI, RRC signaling, or MAC CE signaling, whether to monitor the PDCCH scrambled by the P-RNTI on the PO of the PF of the first terminal device.

And if the monitoring opportunity of the first PEI does not exist, the first terminal equipment monitors the PDCCH scrambled by the P-RNTI on the PO of the PF of the first terminal equipment. For example: in the first option and the second option for determining the listening timing of the first PEI, there may be a case where there is no listening timing of the first PEI.

In summary, in the embodiment of the present application, the first terminal device receives the minimum time offset between the first PEI and the reference time, and the number of SMTCs that need to be separated between the first PEI and the reference time. And the first terminal equipment determines the monitoring opportunity of the first PEI according to the minimum time offset and the number of the SMTCs. Wherein the reference time is related to the PF and/or PO of the first terminal device. Therefore, the monitoring time of the first PEI corresponding to the PO of the first terminal equipment can be determined.
