Description

Information processing method and device, equipment and computer storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information processing method and apparatus, a device, and a computer storage medium.

Background

The New wireless (NR) system continues a Discontinuous Reception (DRX) mechanism of a Long Term Evolution (LTE) system, so that a terminal device may enter a Discontinuous Reception state without turning on a receiver all the time under the condition of no data Reception, thereby achieving the purpose of saving energy.

In order to further reduce the power consumption of the terminal device, the current NR system introduces an energy-saving signal, that is, the terminal device needs to monitor the energy-saving signal before monitoring a Physical Downlink Control Channel (PDCCH), and if the terminal device knows that the network device has PDCCH message transmission by monitoring the energy-saving signal, the terminal device continues to monitor the PDCCH signal, otherwise, the terminal device does not monitor the corresponding PDCCH signal, but monitors the energy-saving signal at the next time.

In the NR system, a network device may transmit a paging message to a terminal device in an IDLE state (RRC-IDLE), an INACTIVE state (RRC-INACTIVE), and a connected state (RRC-CONNECTION). For power saving reasons, the paging reception of the terminal device also follows the principle of DRX, i.e. the terminal is awake at a certain time to listen for paging messages. However, the terminal device periodically monitors the paging message, which may cause higher power consumption, and there is no corresponding solution for how to transmit the energy saving signal in the scenario of monitoring the paging message.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the attached drawings, which are only used for illustration and are not used to limit the embodiments of the present invention.

It should be noted that the terms "first", "second", and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

First, explanations are made for terms referred to in the present application:

discontinuous Reception (DRX): the network side can configure the terminal equipment to wake up or start DRX (DRX ON) within the time foreseen by the network side, at this time, the radio frequency channel of the terminal equipment is started, and the terminal equipment continuously monitors the PDCCH; similarly, the network side may also configure the terminal device to "sleep" or turn OFF DRX (DRX OFF) for a time predicted by the network side, where the radio frequency channel of the terminal device is turned OFF and the terminal device does not monitor the PDCCH. Thus, if the network side has data to transmit to the terminal device, the network side can schedule the terminal device within the time of DRX ON of the terminal device. And in the time when the terminal equipment is in DRX OFF, the power consumption of the terminal equipment can be reduced because the radio frequency is closed.

DRX defines different operation methods for different Radio Resource Control (RRC) modes, such as an RRC-CONNECTED mode (RRC-CONNECTED) mode or an RRC-IDLE mode (RRC-IDLE) mode, in which a terminal device is located.

The network side may configure discontinuous reception cycles (DRX cycles) for the terminal device under RRC _ CONNECTED, and refer to a schematic diagram of a DRX cycle shown in fig. 1, where one DRX cycle is composed of an On Duration (On Duration) and a non-On Duration (Opportunity for DRX). In the On Duration, the terminal equipment monitors and receives a downlink channel and signals including a PDCCH; in Opportunity for DRX, the terminal device does not receive a downlink channel and a signal of a PDCCH to reduce power consumption. The terminal device in RRC-IDLE state needs to receive the Paging message in a manner similar to DRX, and there is a Paging Occasion (PO) within one DRX Paging cycle, and the terminal device only receives the Paging message at the PO and does not receive the Paging message at a time other than the PO, so as to achieve the purpose of saving power. During PO, the terminal device determines whether there is a paging message by detecting a PDCCH signal scrambled by a P-RNTI.

Energy-saving signals: in the fifth generation (5G, 5) ^th Generation) has raised higher demands on energy saving of terminal equipment in the evolution of mobile communication systems; to achieve further power savings, NR systems introduce power saving signals. The power save signal is used in conjunction with the DRX mechanism and the terminal device may receive an indication of the power save signal prior to the On Duration. Referring to a schematic diagram of a power saving signal distribution shown in fig. 2, when the terminal device has data transmission in one DRX cycle (for example, the 0 th DRX cycle or the 3rd DRX cycle shown in fig. 2), the network device "wakes up" the terminal device through the power saving signal 21, so that the terminal device monitors the PDCCH during the On Duration22 of the DRX cycle; otherwise, when the terminal device has no data transmission in one DRX cycle (e.g. the 1 st DRX cycle and the 2 nd DRX cycle described in fig. 2), the power-saving signal 21 does not "wake up" the terminal device, and the terminal device does not need to monitor the PDCCH during the On Duration22 of the DRX cycle. Compared with the existing DRX mechanism, when the terminal equipment has no data transmission, the terminal equipment can omit the monitoring of the PDCCH during the On Duration period, thereby realizing the reduction of the power consumption of the terminal equipment.

In the related art, the power saving signal may be carried in downlink control information format (DCI format) 2_6 newly defined by third Generation Partnership project (3 gpp) R16; based on this, the network side may configure the terminal device to detect a search space set (search space set) of the PDCCH carrying the DCI format 2_6 to obtain the energy saving signal.

In the energy-saving signal, the number of bit numbers required by a single terminal device is at most 6; the cell sleep indication bit comprises 1 wake indication bit and at most 5 secondary cell sleep indication bits. In practical applications, the power saving signal may carry indication bits of multiple terminal devices to improve resource utilization efficiency. Referring to a schematic diagram of an energy saving signal structure shown in fig. 3, an energy saving signal may carry energy saving related information of N terminal devices (from a 1 st terminal device to an nth terminal device), where the energy saving related information of each terminal device includes an awake indication and a secondary cell dormant indication; in addition, the power saving signal further includes Cyclic Redundancy Check (CRC) information. The network device may notify the starting position of the energy saving related information of each terminal device in the DCI in advance, and further, the network device may also notify the total bit number of the DCI and the PS-RNTI of the scrambled PDCCH of the terminal device.

Paging: in the NR system, a network may transmit a page to a terminal device in an RRC-CONNECTED state, an RRC-INACTIVE (RRC-INACTIVE) state, and an RRC-IDLE state. The paging process may be triggered by the core network to notify the terminal device of receiving the paging request, or the paging process is triggered by the base station to notify the system information update, and notify the terminal device of receiving information such as Earthquake and Tsunami Warning (ETWS) and commercial mobile warning service (CMAS).

After receiving the paging message of the core network, the base station interprets the content of the paging message to obtain a Tracking Area Identity (TAI) list of the terminal device, and pages an air interface in a cell which belongs to a Tracking Area in the list. The core network domain indication of the paging message is not decoded at the base station but passed through to the terminal device. When the air interface transmits the paging message, the base station assembles the paging messages of the UE with the same PO into a paging message, and transmits the paging message to the relevant terminal equipment through the paging channel. In addition, the terminal device receives the paging parameter through the system message, calculates the PO in combination with its own terminal device identification (UE _ ID), and receives the paging message at the corresponding PO.

The terminal device in the RRC-IDLE state may save power through a DRX mechanism, and referring to a Paging occasion distribution diagram shown in fig. 4, the terminal device may monitor a PDCCH scrambled by a P-RNTI through a PO on a Paging Frame (PF) in a DRX Paging cycle to receive a Paging message; wherein, PF indicates which system frame number the paging message should appear, and PO indicates the time when it may appear. Referring to fig. 4, one PF may include 1 or more POs, and a terminal device only needs to monitor the POs belonging to itself per DRX paging cycle.

Synchronization Signal Block (SSB): a Signal structure defined in NR is a set of time-Frequency resources (resource units) transmitted on a basic Orthogonal Frequency Division Multiplexing (OFDM) grid, including a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH). Referring to a time-frequency structure diagram of a synchronization signal block shown in fig. 5, as shown in fig. 5, the synchronization signal block lasts for 4 OFDM symbols in the time domain and 240 Subcarriers (SC) in the frequency domain. The PSS is transmitted on the first OFDM symbol of the synchronous signal block, 127 subcarriers are occupied on a frequency domain, and the rest subcarriers are null; the SSS is transmitted on the third OFDM symbol of the synchronization signal block, the same subcarriers are occupied by the SSS and the SSS has 8 and 9 subcarriers respectively at two ends; the PBCH is transmitted on the second and fourth OFDM symbols of the synchronization signal block. In addition, PBCH is also transmitted using 48 subcarriers for SSS.

In the NR system, the SSB needs to cover the whole cell by means of multi-beam scanning, so that the terminal devices in the cell can receive the SSB conveniently. The multi-beam transmission of SSBs is realized by defining synchronous signal burst sets (SS burst sets), wherein one SS burst set comprises one or more SSBs, and one SSB is used for carrying a synchronous signal and a physical broadcast channel of one beam; therefore, one SS burst set may contain synchronization signals of N beams corresponding to SSBs in a cell, and the maximum number L of SSBs is related to the frequency band of the system. For example, when the frequency band of the system does not exceed 3GHz, the maximum number L of SSBs is 4; when the frequency band of the system is within the range of 3GHz and 6GHz, the maximum number L of SSBs is 8; the maximum number L of SSBs is 64 when the frequency band of the system is within the range of 6GHz and 52.6 GHz.

It should be noted that, in an SS burst set, all SSBs are transmitted in a time window of 5ms and are repeatedly transmitted at a certain period, the period may be configured by an upper layer parameter SSB period (SSB-timing), and the SSB period may be 5ms,10ms,20ms,40ms,80ms,160ms, etc., which is not limited in this embodiment.

Optionally, the communication system may include a plurality of network devices and each network device may include other numbers of terminal devices within a coverage area, which is not limited in this embodiment of the present application.

Optionally, the communication system may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

An embodiment of the present application provides an information processing method, which is applied to a terminal device 620 shown in fig. 6, and refers to a schematic flow diagram of an information processing method shown in fig. 7, where the method includes:

step 710, receiving a first reference signal; the first reference signal is used for bearing energy-saving related information of a paging message of the terminal equipment;

and 720, determining a paging processing mode of the terminal equipment based on the energy-saving related information.

In practical application, the network device may send an energy saving signal to the terminal device before the PF or PO of the terminal device, and notify the terminal device whether there is a paging message sent to the terminal device through energy saving related information in the energy saving signal. In this way, the terminal device can determine the paging processing mode through the energy saving signal.

In the related art, the energy-saving related information of the paging message of the terminal device is carried by DCI, the DCI coding mode is complex, and more time-frequency resources are occupied, and more time and energy consumption are required when the terminal device analyzes the DCI to obtain the energy-saving related information.

Based on this, an embodiment of the present application provides an information processing method, where energy saving related information of a terminal device is carried by a first reference signal, that is, the terminal device determines whether there is a paging message sent to the terminal device by receiving and analyzing the first reference signal.

In the embodiments provided in the present application, the first Reference Signal may be any type of Reference Signal, such as a Demodulation Reference Signal (DMRS), a downlink channel state information Reference Signal, a Cell-specific Reference Signal (CRS), and the like, and the type of the first Reference Signal is not limited in this embodiment of the present application.

According to the information processing method provided by the embodiment of the application, terminal equipment receives a first reference signal; the first reference signal is used for bearing energy-saving related information of the paging message of the terminal equipment; determining a paging processing mode of the terminal equipment based on the energy-saving related information; the coding mode of the reference signal is simple, and the occupied time-frequency resource is less, so that the energy consumption used when the first reference signal is analyzed can be reduced by carrying the energy-saving related information of the terminal equipment through the first reference signal, and the effect of saving electricity is achieved.

In one possible implementation manner, the step 720 of determining the receiving manner of the paging message based on the energy-saving signal may be implemented by the following steps:

7201, if the energy-saving signal indicates to monitor the PDCCH at a specific paging occasion, determining that the terminal equipment monitors the PDCCH at the specific paging occasion;

step 7202, if the energy saving signal indicates that the PDCCH is not monitored at the specific paging occasion, determining that the terminal device does not monitor the PDCCH at the specific paging occasion.

The specific paging occasion is used for representing a time period for the terminal equipment to detect the paging indication information.

In the embodiment provided by the application, after receiving the first reference signal, the terminal device analyzes the first reference signal to obtain the energy saving related information of the terminal device carried by the first reference information. If the energy-saving related information indicates that the PDCCH is monitored at a specific paging occasion, it indicates that the network device is about to send a paging message corresponding to the terminal device at the specific paging occasion, and at this time, the terminal device monitors the PDCCH scrambled by the P-RNTI at the specific paging occasion (i.e., PF or PO), and detects DCI format 1_0 carried by the PDCCH to acquire the paging message belonging to the terminal device.

In addition, if the energy saving related information indicates that the PDCCH is not monitored at a specific paging occasion, it indicates that there is no paging message corresponding to the terminal device, and the terminal device does not monitor the PDCCH at the specific PF or PO, that is, the terminal device does not detect the DCI format 1_0 scrambled by the P-RNTI at the specific PF or PO.

Therefore, the terminal equipment monitors the PDCCH only under the condition that the energy-saving related information indicates that the PDCCH is monitored at a specific paging occasion, so that the terminal equipment does not need to periodically wake up to monitor the PDCCH, and the power consumption of the terminal equipment is reduced; and the energy-saving related information of the terminal equipment is carried by the first reference signal, so that the energy consumption used when the first reference signal is analyzed can be reduced, and the effect of saving electricity is achieved.

In one possible implementation, the particular paging occasion may include one or more first paging occasions; the first paging occasion is a paging occasion to which the terminal device belongs or a common paging occasion configured by the network device, which is not limited in this embodiment of the present application.

Here, the first paging included in the specific paging occasion may be indicated by the power saving-related information. It can be understood that, in addition to indicating whether the terminal device monitors the PDCCH, the energy saving related information may also indicate a time period for whether the terminal device monitors the PDCCH. Here, the PF or PO included in the paging reception period may be a PF or PO belonging to the terminal device, or a common PF or PO configured by the cell. The embodiments of the present application do not limit this. Therefore, one or more first paging occasions carrying the terminal device paging message are indicated through the energy-saving related information in the first reference signal, and the flexibility of paging processing performed by the terminal device can be improved.

In one possible implementation, the first reference signal is generated in the same manner as the PBCH DMRS in the synchronization signal block.

That is to say, the first reference signal may be generated by reusing the PBCH DMRS in the existing SSB, and the first reference signal is used as an energy saving signal of the terminal device to carry energy saving related information of the terminal device.

It should be noted that the first reference signal is different from the PBCH DMRS carried in the SSB. And the PBCH DMRS carried in the SSB is used for indicating the lowest three bits of an SSB index, and the SSB index identifies the position of the SSB in the SS burst set.

In order to maintain backward compatibility, the PBCH DMRS carried in the current SSB cannot indicate other information as an energy saving signal. However, the first reference signal may be obtained by using a PBCH DMRS generation manner, and the first reference signal is used as energy saving indication information of the terminal device, so that the technical complexity of generating the first reference signal may be reduced.

In practical application, the PBCH DMRS sequence r (m) can be obtained by formula (1).

Wherein j is a complex identifier, c (n) is a pseudo random sequence, and c (n) is initialized according to the formula (2) at the transmission timing of each SSB.

The initialization process of c (n) is described in detail below:

wherein,

identifying the cell; maximum number of SSBs in a half-frame

When the utility model is used, the water is discharged,

n _hf indicated for field (n if SSB is sent in the first field _hf =0, otherwise n _hf = 1), when i _SSB The lowest two bits of the SSB index. Maximum number of SSBs in a half-frame

When the temperature of the water is higher than the set temperature,

at this time i _SSB The lowest three bits indexed by SSB.

It can be seen that different DMRS sequences can be generated due to different initialization sequences. In related art, the PBCH DMRS may include 8 different sequences, and in addition to being used for demodulation of PBCH, the PBCH DMRS may implicitly indicate 8 SSB indexes, i.e., indicate the lowest 3 bits of the SSB indexes, according to the sequence difference. In this way, the terminal device obtains the lowest 3 bits of the SSB index by blindly detecting the sequence of the PBCH DMRS.

In one possible implementation, the sequence length of the first reference signal is the same as or different from the sequence length of the PBCH DMRS in the SSB.

In practical application, the length of PBCH DMRS in SSB is 144. Although the first reference signal is generated in the same manner as the PBCH DMRS in the SSB, the sequence length of the first reference signal may be set to be the same as or different from the sequence length of the PBCH DMRS in the SSB according to actual needs, which is not limited in this embodiment of the application.

According to the above description, the sequence generation manner of the first reference signal may refer to the generation manner of the PBCH DMRS sequence r (m) described above. That is, the first reference signal may also include up to 8 different sequences.

In one possible implementation, different power saving related information is carried by different first reference signal sequences.

In the embodiments provided in the present application, the use of

Indicating energy saving related information. In particular, can be prepared by

Indicating whether the terminal device monitors the PDCCH on the next PF or PO adjacent to the energy-saving signal, and optionally passing through

And indicating whether the terminal equipment carries out paging reception or not.

In one possible example of this, the user may,

the value ranges of (1) and (0); use of

The generated first reference signal sequence may be indicated in the secondA PO or PF with a corresponding relation of a reference signal sequence, or not detecting paging messages on a PDCCH monitoring occasion in the PO; use of

The generated first reference signal sequence may indicate that the paging message is detected on a PO or PF corresponding to the first reference signal sequence, or a PDCCH monitoring occasion in the PO.

In another possible example of an implementation of the method,

the value range of (1) is 0 to 7; using a difference

The values are taken to produce different first reference signal sequences. Wherein, different first reference signal sequences indicate different information, and the first reference signal has 8 different sequences in total, which can indicate 8 different information. For example, referring to a first reference signal distribution diagram shown in FIG. 8, use is made of

The generated first reference signal sequence can indicate that the paging message is detected on 3 POs or PFs or PDCCH monitoring occasions of a PO terminal; the 3 POs or PFs mentioned here may be PFs or POs belonging to the terminal device, or may be common PFs or POs configured by the cell.

In a possible implementation manner, the time-frequency resource of the first reference signal and the time-frequency resource of the synchronization signal block have a corresponding relationship.

In practical applications, before the PF or PO of the terminal device arrives, the terminal device needs to perform time and frequency synchronization with the network side, so that the paging message can be accurately received. In general, the terminal device may perform time-frequency synchronization operation based on the SSB. For example, referring to a distribution diagram of SSBs shown in fig. 9, a terminal device may detect an SSB in an SS burst set to perform time-frequency synchronization operation before a PF or PO arrives, so as to monitor a PDCCH on the PF or PO.

In the embodiment of the application, a corresponding relationship between the first reference signal time frequency resource and the SSB time frequency resource may be established in advance. The corresponding relationship here may be that the time-frequency resource of the first reference signal is located within a preset range of the SSB time-frequency resource, or the time-frequency resource of the first reference signal is adjacent to the SSB time-frequency resource, which is not limited in this embodiment of the application.

Therefore, when the terminal equipment searches for the SSB for time-frequency synchronization, the first reference signal can be acquired at the time-frequency resource corresponding to the SSB time-frequency resource, and the energy-saving related information of the paging message of the terminal equipment is determined based on the first reference signal.

It should be noted that the network device may send the SSBs in a beam scanning manner, that is, send different SSBs on different beams in a time division multiplexing manner, where a set of SSBs in the beam scanning is an SS burst set. The SSB in the embodiment of the present application may be any one of SS burst sets.

That is, the terminal device may detect the first reference signal at the time-frequency resource corresponding to each SSB time-frequency resource in the SS burst set. The first reference signals and the SSBs have a corresponding relationship, that is, one SSB may correspond to one first reference signal.

In the embodiments provided in the present application, the correspondence between the time-frequency resource of the first reference signal and the time-frequency resource of the synchronization signal block may include multiple types, three of which are described in detail below:

a first kind,

In a possible implementation manner, the correspondence between the time-frequency resources of the first reference signal and the time-frequency resources of the synchronization signal block includes:

the frequency domain resource location of the first reference signal is at least partially overlapped with the frequency domain resource location of the SSB, and the time domain resource location of the first reference signal is not overlapped with the time domain resource location of the SSB.

It is to be appreciated that the first reference signal can be disposed on a different OFDM symbol having the same bandwidth as the SSB.

For example, referring to a schematic diagram of a time-frequency structure of an exemplary first reference signal shown in fig. 10, the first reference signal may be located on a part of subcarriers or all subcarriers of subcarriers numbered 0 to 239, and the power saving signal is located on an OFDM symbol numbered 4 of the OFDM symbol.

It should be noted that the number of subcarriers occupied by the first reference signal in the frequency domain may be determined according to the sequence length of the first reference signal in practical application.

A second kind,

the time domain resource position of the first reference signal is at least partially overlapped with the time domain resource position occupied by the SSB, and the frequency domain resource position of the first reference signal is not overlapped with the frequency domain resource position of the SSB.

That is, the first reference signal may be disposed at a position overlapping with an OFDM symbol of the SSB, the subcarrier being different.

For example, referring to a time-frequency structure diagram of an exemplary first reference signal shown in fig. 11, the first reference signal may be located on subcarriers numbered 249 to M +248, and the first reference signal is located on an OFDM symbol numbered 0. Here, M is the length of the power saving signal.

A third one,

the OFDM symbol of the first reference signal is the same as the OFDM symbol occupied by the primary synchronization signal PSS in the SSB, and the time domain resource of the first reference signal comprises a first subcarrier set and/or a second subcarrier set; the first subcarrier set and the second subcarrier set are not overlapped with the subcarrier set occupied by the primary synchronization signal PSS.

It is to be understood that, referring to fig. 12 illustrating a time-frequency structure diagram of an exemplary first reference signal, that is, the first reference signal may be located on an OFDM symbol of the PSS in the SSB, i.e., on an OFDM symbol numbered 0, and the first reference signal occupies the first subcarrier set 121 and/or the second subcarrier set 122. Here, the first subcarrier set may be some subcarriers or all subcarriers numbered from 0 to 47 in the SSB time-frequency structure, and the second subcarrier set may be some subcarriers or all subcarriers numbered from 192 to 239 in the SSB time-frequency structure.

Illustratively, the time-frequency resource occupied by the first reference signal is an OFDM symbol numbered 0, and the frequency-domain resource occupied by the first reference signal is subcarriers numbered 0 to 47 (48 subcarriers in total); or, the time-frequency resource occupied by the first reference signal is the OFDM symbol numbered 0, and the frequency-domain resource occupied by the first reference signal is the subcarriers numbered 0 to 47 and numbered 192 to 239 (total 96 subcarriers).

Therefore, the first reference signal is carried near the time frequency resource position of the SSB, and when the terminal equipment detects the time frequency synchronous operation of the SSB, the first reference signal can be detected near the time frequency resource of the SSB, so that the extra power consumption caused by independently detecting the first reference signal is avoided.

In the embodiments provided by the present application, although the PBCH DMRS is generated in the same manner in the first reference signal and the SSB, the sequence length of the first reference signal is the same as or different from the sequence length of the PBCH DMRS in the SSB. Next, referring to a time-frequency structure diagram of the first reference signal shown in fig. 13, a relationship between the sequence length of the first reference signal and the sequence length of the PBCH DMRS in the SSB is exemplarily illustrated.

For example, referring to the time-frequency structure shown in fig. 13, the first reference signal may occupy OFDM symbols numbered 0 and subcarriers numbered 0-47 and 192-239; the sequence length of the first reference signal is 96. In another example, a first reference signal having a sequence length of 48 may also occupy the OFDM symbol numbered 0 and the subcarriers numbered 0-47 or 192-239. Here, the sequence length of the first reference signal, which is the power saving signal, may be controlled to 96 or less by using a specific coding scheme.

It should be noted that, in fig. 13, the up and down 48 subcarriers may be combined to carry one first reference signal (that is, the length of the first reference signal is less than or equal to 96), or may also carry one first reference signal respectively (that is, the sequence length of each first reference signal is less than or equal to 48). Here, the first reference sequences at different positions may correspond to different terminal device groups, or to different POs or PFs, etc. The embodiments of the present application do not limit this.

In one possible implementation, the first reference signal and the synchronization signal block have a corresponding relationship, wherein the corresponding relationship is a Quasi Co-Location (QCL). It is to be understood that the first reference signal and the SSB are transmitted using the same antenna port.

It should be noted that, due to the multi-beam transmission, a plurality of PDCCH monitoring occasions exist in one PO, and each PDCCH monitoring occasion corresponds to one beam. Therefore, in the embodiments provided in the present application, the PDCCH monitoring occasion in the PO corresponds to the SSB in the SS burst set, and the PDCCH monitoring occasion in the PO also corresponds to the first DMRS.

Each or every few listening occasions are associated with an SSB for multi-beam transmission of paging messages. As shown in fig. 14, the SS burst set includes multiple SSBs, and each SSB141 corresponding to each first DMRS signal corresponds to one PDCCH monitoring occasion 142 in the PO.

In a possible implementation manner, before the step 710 receives the energy saving signal, the following steps may be further performed:

step 701, determining a time offset parameter, a minimum time interval, and a period of a synchronization signal block;

step 702, determining a receiving time of the first reference signal based on the time offset parameter, the minimum time interval, and the period of the synchronization signal block.

Correspondingly, step 710 receives a power saving signal, which includes:

the first reference signal is received based on a reception timing of the first reference signal.

Here, since the SS burst sets are transmitted periodically, there may be multiple periods of SS burst set transmission before the PO or PF of the terminal device arrives, and it is necessary to determine at which SS burst sets the energy saving signals are carried.

In the embodiments provided in the present application, the listening time of the first reference signal may be determined at a period of the SS burst set configured in combination (i.e., a period of the SSB) by the time offset parameter and the minimum time interval.

Here, the time offset parameter may be a value predetermined by the terminal device and the network device, or may be configured by the network device through a system message, which is not limited in this embodiment of the present application.

The terminal device needs to perform device wake-up and initialization after wake-up before the PF or PO is reached, so that the terminal device needs to receive a complete power saving signal before the minimum time interval starts, and the terminal device performs initialization after wake-up in the minimum time interval before the PF or PO is reached, so that the terminal device does not need to monitor the power saving signal in the minimum time interval.

Here, the minimum time interval is related to the capability of the terminal device. Referring to the minimum time interval example shown in table 1, two terminal devices using the same subcarrier spacing (e.g., 15 kHz) initialize a faster terminal device with a shorter minimum time interval (e.g., value 1 in table 1) and initialize a slower terminal with a longer minimum time interval (e.g., value 2 in table 1). Here, the unit of the minimum time interval is a slot (slot).

TABLE 1

In the embodiments provided in the present application, the listening timing of the first reference signal may be determined at a period of the SS burst set configured in combination by a time offset parameter and a minimum time interval. As shown in fig. 15, before the PF or PO arrives, the terminal device receives the first reference signal within the complete set of SSB bursts that satisfy the configured time offset parameter and the minimum time interval.

In the embodiments provided in the present application, the terminal device is in a radio resource control RRC idle state or an RRC inactive state.

Based on the foregoing embodiments, an embodiment of the present application further provides an information processing method, which is applied to the network device 610 shown in fig. 6, and the method includes:

step 810, sending a first reference signal to the terminal device, where the first reference signal is used to carry energy-saving related information of a paging message of the terminal device, so that the terminal device determines a paging processing mode of the terminal device based on the energy-saving related information.

Here, the network device may send the first reference signal to the terminal device before sending the paging message to the terminal device, so that when the paging message arrives at the terminal device, the terminal device can determine whether to monitor the PDCCH to receive the paging message according to the energy saving related information carried in the first reference signal.

In the embodiment of the application, the network equipment loads the energy-saving related information in the first reference signal and sends the energy-saving related information to the terminal equipment; in this way, the terminal device may determine a paging processing mode of the terminal device based on the energy saving related information; here, the reference signal is used for bearing the energy-saving first-off information, so that the energy consumption used in analyzing the first reference signal can be reduced, and the effect of saving electricity is achieved.

In one possible implementation, the first reference signal is generated in the same manner as the demodulation reference signal in the synchronization signal block.

It should be noted that the first reference signal is different from the PBCH DMRS carried in the SSB. The PBCH DMRS carried in the SSB is used for indicating the lowest three bits of an SSB index, and the SSB index identifies the position of the SSB in an SS burst set.

In order to maintain backward compatibility, the PBCH DMRS carried in the current SSB cannot indicate other information as an energy saving signal. However, the first reference signal may be obtained by using a PBCH DMRS generation method, and the first reference signal is used as energy saving indication information of the terminal device, so that the technical complexity of generating the first reference signal may be reduced.

In one possible implementation, the sequence length of the first reference signal is the same as or different from the sequence length of the demodulation reference signal.

In practical application, the length of PBCH DMRS in SSB is 144. Although the first reference signal is generated in the same manner as the PBCH DMRS in the SSB, the sequence length of the first reference signal may be set to be the same as or different from the sequence length of the PBCH DMRS in the SSB according to actual needs, and this is not limited in this embodiment of the application.

In one possible implementation, the first reference signal includes a plurality of sequences; different first reference signal sequences carry different power saving related information.

Here, the first reference signal is generated in the same manner as the PBCH DMRS in the SSB, that is, the first reference signal may also include at most 8 different sequences. Different sequences may indicate carrying different energy saving related information.

In one possible implementation, the first reference signal has a corresponding relationship with the synchronization signal block; the corresponding relationship comprises a quasi co-location relationship.

In the embodiments provided in the present application, the time-frequency resource of the first reference signal and the time-frequency resource of the synchronization signal block have a corresponding relationship.

the frequency domain resource position of the first reference signal is at least partially overlapped with the frequency domain resource position of the synchronization signal block, and the time domain resource position of the first reference signal is not overlapped with the time domain resource position of the synchronization signal block.

the time domain resource position of the first reference signal is at least partially overlapped with the time domain resource position of the synchronization signal block, and the frequency domain resource position of the first reference signal is not overlapped with the frequency domain resource position of the synchronization signal block.

the OFDM symbol of the first reference signal is the same as the OFDM symbol occupied by the main synchronization signal in the synchronization signal block, and the frequency domain resource of the first reference signal comprises a first subcarrier set and/or a second subcarrier set;

the first subcarrier set and the second subcarrier set are not overlapped with the subcarrier set occupied by the main synchronizing signal.

In the embodiment provided by the application, the network device may bear the energy-saving signal on the time-frequency resource within the preset range of the SSB time-frequency resource to send the energy-saving signal, that is, the network device sends the energy-saving signal on the time-frequency resource near the SSB, so that the terminal device may detect the energy-saving signal near the SSB time-frequency resource position when detecting the SSB to perform time-frequency synchronization operation before the PF or PO arrives, thereby avoiding additional power consumption caused by separately detecting the energy-saving signal and achieving the effect of saving power.

Therefore, the energy-saving signal is borne near the time-frequency resource position of the SSB, and the terminal equipment can detect the energy-saving signal when detecting the time-frequency synchronous operation of the SSB, so that the additional power consumption caused by independently detecting the energy-saving signal is avoided.

In the embodiment provided by the present application, before the step 810 sends the energy saving signal to the terminal device, the following steps may also be performed:

step 801, sending configuration information to terminal equipment; the configuration information includes a time offset parameter.

It is understood that the network device may configure the terminal device with a time offset parameter, so that the terminal device may determine the receiving moment of the power saving signal based on the time offset parameter.

In one possible implementation, the configuration information may be carried by system information.

In the embodiments provided in this application, the synchronization signal block is any one of a set of synchronization signal bursts transmitted by a network device.
