Abstract
Description
Technical Field
[0001] The present application relates to the field of communication technology, and in particular to an information processing method and apparatus, equipment, and computer storage medium. Background Art
[0002] The New Radio (NR) system continues the discontinuous reception (DRX) mechanism of the Long Term Evolution (LTE) system, so that when there is no data to be received, the terminal device does not need to keep the receiver turned on, but enters a discontinuous reception state, thereby achieving energy saving.
[0003] In order to further reduce the power consumption of terminal devices, the current NR system introduces energy-saving signals, that is, the terminal device needs to monitor the energy-saving signal before monitoring the physical downlink control channel (PDCCH). If the terminal device learns that the network device has a PDCCH message to send by monitoring the energy-saving signal, it 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 moment.
[0004] In the NR system, network equipment can send paging messages to terminal devices in idle state (RRC-IDLE), inactive state (RRC-INACTIVE), and connected state (RRC-CONNECTION). For power saving considerations, the paging reception of terminal devices also follows the DRX principle, that is, the terminal is awakened at a specific time to listen to paging messages. However, the periodic monitoring of paging messages by terminal devices will generate higher power consumption.

[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present invention.
[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.
[0047] First, the nouns involved in this application are explained:
[0048] Discontinuous Reception (DRX): The network side can configure the terminal device to "wake up" or start DRX (DRX ON) at a time predicted by the network side. At this time, the terminal device's RF channel is turned on and the terminal device continues to monitor PDCCH; similarly, the network side can also configure the terminal device to "sleep" or turn off DRX (DRX OFF) at a time predicted by the network side. At this time, the terminal device's RF channel is turned off and the terminal device does not monitor PDCCH. In this way, if the network side has data to transmit to the terminal device, the network side can schedule the terminal device during the DRX ON time of the terminal device. During the time when the terminal device is in DRX OFF, the power consumption of the terminal device can be reduced because the RF is turned off.
[0049] DRX defines different operation methods for different Radio Resource Control (RRC) modes of the terminal device, such as RRC-CONNECTED mode or RRC-IDLE mode.
[0050] The network side can configure a discontinuous reception cycle (DRX cycle) for the terminal device under RRC_CONNECTED, refer to Figure 1A schematic diagram of a DRX cycle is shown, and a DRX cycle consists of continuous monitoring time (On Duration) and non-monitoring time (Opportunity for DRX). During the On Duration, the terminal device monitors and receives downlink channels and signals including PDCCH; during the Opportunity for DRX, the terminal device does not receive downlink channels and signals of PDCCH to reduce power consumption. Terminal devices in the RRC-IDLE state need to receive paging messages in a similar manner to DRX. There is a paging occasion (Paging Occasion, PO) in a DRX paging cycle. The terminal device only receives paging messages during the PO, and does not receive paging messages outside the PO to achieve the purpose of power saving. During the PO period, the terminal device determines whether there is a paging message by detecting the PDCCH signal scrambled by the P-RNTI.
[0051] Energy-saving signal: In the fifth generation (5G, 5 th In the evolution of the NR (New Generation) mobile communication system, higher requirements are placed on the energy saving of terminal devices. In order to achieve further energy saving, the NR system introduces energy saving signals. The energy saving signals are used in conjunction with the DRX mechanism, and the terminal device can receive the indication of the energy saving signal before the On Duration. Figure 2 A schematic diagram of energy-saving signal distribution is shown, when the terminal device has data transmission in a DRX cycle (for example, Figure 2 The network device "wakes up" the terminal device through the energy-saving signal 21, so that the terminal device monitors the PDCCH during the On Duration 22 of the DRX cycle; otherwise, when the terminal device has no data transmission in a DRX cycle (for example, Figure 2 The energy-saving signal 21 does not "wake up" the terminal device during the On Duration 22 of the DRX cycle. Compared with the existing DRX mechanism, when the terminal device has no data transmission, the terminal device can omit the monitoring of the PDCCH during the On Duration period, thereby reducing the power consumption of the terminal device.
[0052] In the related art, the energy-saving signal can be carried by the downlink control information format (DCI format) 2_6 newly defined in the 3rd Generation Partnership Project (3GPP) R16; based on this, the network side can configure the terminal device to detect the search space set (searchspace set) of the PDCCH carrying DCI format 2_6 to obtain the energy-saving signal.
[0053] In the energy-saving signal, the number of bits required for a single terminal device is up to 6, including 1 wake-up indication bit and up to 5 secondary cell sleep indication bits. In practical applications, the energy-saving signal can carry the indication bits of multiple terminal devices to improve resource utilization efficiency. Figure 3 A schematic diagram of an energy-saving signal structure is shown, where the energy-saving signal can carry energy-saving related information of N terminal devices (from the first terminal device to the Nth terminal device), and the energy-saving related information of each terminal device includes a wake-up indication and a secondary cell sleep indication; in addition, the energy-saving signal also includes cyclic redundancy check (CRC) information. The network device can pre-notify each terminal device of the starting position of the energy-saving related information in the DCI, and further, the network device can also notify the terminal device of the total number of bits of the DCI and the PS-RNTI of the scrambled PDCCH.
[0054] Paging: In the NR system, the network can send paging to terminal devices in the RRC-CONNECTED state, RRC-INACTIVE state, and RRC-IDLE state. The paging process can be triggered by the core network to notify the terminal device to receive a paging request, or the paging process can be triggered by the base station to notify system information updates and notify the terminal device to receive information such as Earthquake Tsunami Warning (ETWS) and Commercial Mobile Warning Service (CMAS).
[0055] Among them, after the base station receives the paging message from the core network, it interprets the content, obtains the tracking area identity (TAI) list of the terminal device, and performs air interface paging on the cells of the tracking areas in the list. The core network domain indication of the paging message will not be decoded at the base station, but will be transparently transmitted to the terminal device. When transmitting paging messages over the air interface, the base station aggregates the paging messages of UEs with the same PO into one paging message, and transmits it to the relevant terminal devices through the paging channel. In addition, the terminal device receives paging parameters through system messages, calculates the PO based on its own terminal device identity (UE_ID), and receives the paging message at the corresponding PO.
[0056] Terminal devices in RRC-IDLE state can save power through the DRX mechanism. Figure 4 The diagram shows a paging occasion distribution diagram. The terminal device can receive the paging message by monitoring the PDCCH scrambled by P-RNTI on the PO on the paging frame (PF) in a DRX paging cycle. PF indicates the system frame number on which the paging message should appear, and PO indicates the possible time when the paging message may appear. Figure 4 As shown, a PF may include one or more POs, and in each DRX paging cycle, the terminal device only needs to monitor the PO belonging to itself.
[0057] Synchronization Signal Block (SSB): A signal structure defined in NR, a set of time-frequency resources (resource units) transmitted on the basic orthogonal frequency division multiplexing (OFDM) grid, including the primary synchronization signal (PSS), the secondary synchronization signal (SSS) and the physical broadcast channel (PBCH). Figure 5 A schematic diagram of the time-frequency structure of a synchronization signal block is shown in FIG. Figure 5 As shown in the figure, the synchronization signal block lasts for 4 OFDM symbols in the time domain and 240 subcarriers (SC) in the frequency domain. Among them, PSS is sent on the first OFDM symbol of the synchronization signal block, occupies 127 subcarriers in the frequency domain, and the remaining subcarriers are empty; SSS is sent on the third OFDM symbol of the synchronization signal block, occupies the same subcarriers as PSS, and 8 and 9 subcarriers are left empty at both ends of SSS respectively; PBCH is sent on the second and fourth OFDM symbols of the synchronization signal block. In addition, PBCH is also sent using 48 subcarriers at both ends of SSS.
[0058] In the NR system, SSB needs to cover the entire cell through multi-beam scanning to facilitate reception by terminal devices in the cell. The multi-beam transmission of SSB is achieved by defining a synchronization signal burst set (SS burst set). An SS burst set contains one or more SSBs. An SSB is used to carry the synchronization signal and physical broadcast channel of a beam. Therefore, an SS burst set can contain the synchronization signals of N beams corresponding to the SSB in the cell. The maximum number of SSBs L 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 of SSBs L is 4; when the frequency band of the system is between 3GHz and 6GHz, the maximum number of SSBs L is 8; when the frequency band of the system is between 6GHz and 52.6GHz, the maximum number of SSBs L is 64.
[0059] It should be noted that, in an SS burst set, all SSBs are sent within a 5ms time window and are repeatedly sent at a certain period. The period can be configured by the upper-layer parameter SSB period (SSB-timing). The SSB period can be 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc., and this is not limited to the embodiments of the present application.

[0063] Figure 6One network device and one terminal device are shown exemplarily. Optionally, the communication system may include multiple network devices and each network device may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.
[0064] Optionally, the communication system may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.
[0065] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0066] The present application provides an information processing method for Figure 6 In the terminal device 620 shown in FIG. Figure 7 A flow chart of an information processing method is shown, the method comprising:
[0067] Step 710: Receive a first reference signal; the first reference signal is used to carry energy-saving related information of a paging message of a terminal device;
[0068] Step 720: Determine the paging processing method of the terminal device based on the energy-saving related information.
[0069] In actual applications, the network device can send an energy-saving signal to the terminal device before the PF or PO of the terminal device, and inform the terminal device whether there will be a paging message sent to the terminal device through the energy-saving related information in the energy-saving signal. In this way, the terminal device can determine the paging processing method through the energy-saving signal.
[0070] In the related technology, energy-saving related information of the terminal device paging message is carried by DCI. The DCI encoding method is complex and occupies more time and frequency resources. It takes a lot of time and energy for the terminal device to parse the DCI to obtain energy-saving related information.
[0071] Based on this, an embodiment of the present application provides an information processing method, which carries energy-saving related information of a terminal device through a first reference signal. That is, the terminal device determines whether there will be a paging message sent to itself by receiving and parsing the first reference signal.
[0072] 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), etc. The embodiment of the present application does not limit the type of the first reference signal.
[0073] The information processing method provided in the embodiment of the present application comprises: a terminal device receives a first reference signal; the first reference signal is used to carry energy-saving related information of a paging message of the terminal device; based on the energy-saving related information, a paging processing method of the terminal device is determined; the coding method of the reference signal is simple and occupies fewer time-frequency resources. Therefore, by carrying the energy-saving related information of the terminal device through the first reference signal, the energy consumption used in parsing the first reference signal can be reduced, thereby achieving a power saving effect.
[0074] In a possible implementation, step 720 of determining the receiving mode of the paging message based on the energy-saving signal can be implemented by the following steps:
[0075] Step 7201: If the energy-saving signal indicates to monitor the PDCCH at a specific paging occasion, determine that the terminal device monitors the PDCCH at the specific paging occasion;
[0076] Step 7202: If the energy-saving signal indicates not to monitor the PDCCH at a specific paging occasion, determine that the terminal device does not monitor the PDCCH at the specific paging occasion.
[0077] The specific paging opportunity is used to represent the time period during which the terminal device detects the paging indication information.
[0078] In the embodiment provided in the present application, after receiving the first reference signal, the terminal device parses 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 to monitor the PDCCH at a specific paging opportunity, it indicates that the network device is about to send a paging message corresponding to the terminal device at the specific paging opportunity. At this time, the terminal device monitors the PDCCH scrambled by the P-RNTI at the specific paging opportunity (i.e., PF or PO), and detects the DCI format 1_0 carried by the PDCCH to obtain the paging message belonging to the terminal device.
[0079] In addition, if the energy-saving related information indicates not to monitor PDCCH at a specific paging time, it means that there is no paging message corresponding to the terminal device, and the terminal device does not monitor PDCCH on the specific PF or PO. In other words, the terminal device does not detect P-RNTI-encrypted DCI format 1_0 on the specific PF or PO.
[0080] It can be seen from this that the terminal device will only monitor the PDCCH when the energy-saving related information indicates to monitor the PDCCH at a specific paging opportunity. In this way, the terminal device does not need to wake up periodically to monitor the PDCCH, thereby reducing the power consumption of the terminal device; and by carrying the energy-saving related information of the terminal device through the first reference signal, the energy consumption used in parsing the first reference signal can be reduced, thereby achieving the effect of power saving.
[0081] In a possible implementation, the specific 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 public paging occasion configured by the network device, which is not limited in the embodiment of the present application.
[0082] Here, the first paging included in a specific paging occasion can be indicated by energy-saving related information. It can be understood that in addition to indicating whether the terminal device monitors PDCCH, the energy-saving related information can also indicate the time period whether the terminal device monitors PDCCH. Here, the PF or PO included in the time period of paging reception can be the PF or PO belonging to the terminal device, or it can be a public PF or PO configured by the cell. The embodiments of the present application are not limited to this. In this way, by indicating one or more first paging occasions carrying the paging message of the terminal device through the energy-saving related information in the first reference signal, the flexibility of the terminal device in performing paging processing can be improved.
[0083] In a possible implementation manner, the first reference signal is generated in the same manner as the PBCH DMRS in the synchronization signal block.
[0084] That is to say, the first reference signal can be generated by reusing the PBCH DMRS method in the existing SSB, and the first reference signal is used as the energy-saving signal of the terminal device to carry the energy-saving related information of the terminal device.
[0085] 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 to indicate the lowest three bits of the SSB index, which identifies the position of the SSB in the SS burst set.
[0086] In order to maintain backward compatibility, the PBCH DMRS currently carried in the SSB cannot be used as an energy-saving signal to indicate other information. However, the PBCH DMRS generation method can be used to obtain the first reference signal, and the first reference signal can be used as the energy-saving indication information of the terminal device, so that the technical complexity of generating the first reference signal can be reduced.
[0087] In practical applications, the PBCH DMRS sequence r(m) can be obtained by formula (1).
[0088]
[0089] Wherein, j is a complex identifier, c(n) is a pseudo-random sequence, and c(n) is initialized according to formula (2) at the time of each SSB transmission.
[0090] The initialization process of c(n) is described in detail below:
[0091]
[0092] in, It is the cell identifier; when the maximum number of SSBs in a half frame hour, n hf Half-frame indication (if SSB is sent in the first half-frame, n hf =0, otherwise, n hf =1), then i SSB The lowest two digits of the SSB index. hour, At this time SSB The lowest three digits of the SSB index.
[0093] It can be seen that different initialization sequences can generate different DMRS sequences. In the related art, PBCH DMRS can include 8 different sequences. In addition to being used for PBCH demodulation, PBCH DMRS can also implicitly indicate 8 SSB indexes according to different sequences, that is, indicating the lowest 3 bits of the SSB index. In this way, the terminal device obtains the lowest 3 bits of the SSB index by blindly detecting the sequence of PBCH DMRS.
[0094] In a 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.
[0095] In practical applications, the length of the PBCH DMRS in the 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 can 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 the embodiments of the present application.
[0096] According to the above description, the sequence generation method of the first reference signal can refer to the above PBCH DMRS sequence r(m) generation method. That is, the first reference signal can also include up to 8 different sequences.
[0097] In a possible implementation manner, different first reference signal sequences are used to carry different energy-saving related information.
[0098] In the embodiments provided in this application, it is possible to use Indicates energy saving related information. Indicates whether the terminal device monitors the PDCCH on the next PF or PO adjacent to the energy-saving signal. Indicates the time period during which the terminal device receives paging messages.
[0099] In a possible example, The value range is 0 and 1; use The generated first reference signal sequence may indicate that a paging message is not detected at a PO or PF corresponding to the first reference signal sequence, or a PDCCH monitoring opportunity in the PO; using The generated first reference signal sequence may indicate to detect a paging message at a PO or PF corresponding to the first reference signal sequence, or at a PDCCH monitoring opportunity in the PO.
[0100] In another possible example, The value range is 0-7; use different Different first reference signal sequences are generated by taking values. Different first reference signal sequences indicate different information. There are 8 different sequences of first reference signals in total, which can indicate 8 different information. For example, Figure 8 A schematic diagram of a first reference signal distribution is shown, using The generated first reference signal sequence can indicate the detection of paging messages at three POs or PFs, or the PO terminal PDCCH monitoring opportunity; the three POs or PFs mentioned here can be the PFs or POs belonging to the terminal device, or the public PFs or POs configured by the cell.
[0101] In a possible implementation, the time-frequency resources of the first reference signal correspond to the time-frequency resources of the synchronization signal block.
[0102] In actual applications, before the arrival of its own PF or PO, the terminal device needs to perform time and frequency synchronization with the network side so that it can accurately receive the paging message. Generally, the terminal device can perform time and frequency synchronization based on SSB. For example, refer to Fig. 9 An SSB distribution diagram is shown Figure 1 , the terminal device can detect the SSB in the SS burst set and perform time-frequency synchronization before the PF or PO arrives, so as to monitor the PDCCH on the PF or PO.
[0103] In an embodiment of the present application, a correspondence between the first reference signal time-frequency resource and the SSB time-frequency resource may be pre-established. The correspondence may be that the time-frequency resource of the first reference signal is within a preset range of the SSB time-frequency resource, or that the time-frequency resource of the first reference signal is adjacent to the SSB time-frequency resource, which is not limited in the embodiment of the present application.
[0104] Based on this, when the terminal device searches for SSB for time and frequency synchronization, it can obtain the first reference signal at the time and frequency resources that correspond to the SSB time and frequency resources, and determine the energy-saving related information of the terminal device paging message based on the first reference signal. In this way, the extra power consumption caused by detecting the first reference signal alone is avoided, thereby achieving the effect of power saving.
[0105] It should be noted that the network device may send SSB in a beam scanning manner, that is, send different SSBs on different beams in a time division multiplexing form, and the SSB set in the beam scanning is an SS burst set. The SSB in the embodiment of the present application can be any one of the SS burst sets.
[0106] That is, the terminal device can 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 signal has a corresponding relationship with the SSB, that is, one SSB can correspond to one first reference signal.
[0107] In the embodiments provided in the present application, the correspondence between the time-frequency resources of the first reference signal and the time-frequency resources of the synchronization signal block may include multiple types, three of which are described in detail below:
[0108] The first one,
[0109] 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:
[0110] The frequency domain resource position of the first reference signal at least partially overlaps with the frequency domain resource position of the SSB, and the time domain resource position of the first reference signal does not overlap with the time domain resource position of the SSB.
[0111] It can be understood that the first reference signal can be set on a different OFDM symbol with the same bandwidth as the SSB.
[0112] Exemplary, reference Fig.10 An exemplary time-frequency structure of a first reference signal is shown in FIG. Figure 1 The first reference signal may be located on some or all of the subcarriers numbered 0-239, and the energy-saving signal is located on the OFDM symbol numbered 4.
[0113] It should be noted that the number of subcarriers occupied by the first reference signal in the frequency domain can be determined according to the sequence length of the first reference signal in an actual application.
[0114] The second type
[0115] 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:
[0116] The time domain resource position of the first reference signal at least partially overlaps with the time domain resource position occupied by the SSB, and the frequency domain resource position of the first reference signal does not overlap with the frequency domain resource position of the SSB.
[0117] That is, the first reference signal may be set at a position overlapping with the OFDM symbol of the SSB and having a different subcarrier.
[0118] Exemplary, reference Fig.11 An exemplary time-frequency structure of a first reference signal is shown in FIG. Figure 2 , 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 energy-saving signal.
[0119] The third type
[0120] 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:
[0121] 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 resources of the first reference signal include a first subcarrier set and / or a second subcarrier set; the first subcarrier set and the second subcarrier set do not overlap with the subcarrier set occupied by the primary synchronization signal PSS.
[0122] Understandably, reference Fig.12 An exemplary time-frequency structure of a first reference signal is shown in FIG. Figure 3 , the first reference signal may be located on the OFDM symbol of the PSS in the SSB, that is, the 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 part of the subcarriers or all of the subcarriers numbered 0 to 47 in the SSB time-frequency structure, and the second subcarrier set may be part of the subcarriers or all of the subcarriers numbered 192 to 239 in the SSB time-frequency structure.
[0123] Exemplarily, the time-frequency resources occupied by the first reference signal are the OFDM symbol numbered 0, and the frequency domain resources occupied by the first reference signal are the subcarriers numbered 0 to 47 (48 subcarriers in total); or, the time-frequency resources occupied by the first reference signal are the OFDM symbol numbered 0, and the frequency domain resources occupied by the first reference signal are the subcarriers numbered 0 to 47 and numbered 192 to 239 (96 subcarriers in total).
[0124] In this way, the first reference signal is carried near the time-frequency resource position of the SSB. When the terminal device detects the SSB for time-frequency synchronization operation, it can detect the first reference signal near the SSB time-frequency resource, thereby avoiding the extra power consumption caused by detecting the first reference signal alone.
[0125] In the embodiment provided in the present application, although the first reference signal and the PBCH DMRS in the SSB are generated in the same manner, 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. Fig.13 The time-frequency structure of the first reference signal shown is shown in FIG. Figure 4 , which illustrates the relationship between the sequence length of the first test signal and the sequence length of the PBCH DMRS in the SSB.
[0126] Exemplary, reference Fig.13 In the time-frequency structure shown in FIG. 1 , the first reference signal may occupy the OFDM symbol numbered 0, and the subcarriers numbered 0-47 and 192-239; the sequence length of the first reference signal is 96. In another example, the first reference signal may also occupy the OFDM symbol numbered 0, and the subcarriers numbered 0-47 or 192-239, and the sequence length of the first reference signal is 48. Here, a specific coding method may be used to control the sequence length of the first reference signal as an energy-saving signal to be less than or equal to 96.
[0127] It should be noted that Fig.13 The 48 subcarriers in the upper and lower parts can be combined to carry a first reference signal (i.e., the length of the first reference signal is less than or equal to 96), or can be separately carried a first reference signal (i.e., the sequence length of each first reference signal is less than or equal to 48). Here, the first reference sequences at different positions can correspond to different terminal device groups, or to different POs or PFs, etc. This embodiment of the present application is not limited to this.
[0128] In a possible implementation, the first reference signal and the synchronization signal block have a corresponding relationship, wherein the corresponding relationship is a quasi co-location relationship (Quasi Co-Location, QCL). It can be understood that the first reference signal and the SSB are transmitted using the same antenna port.
[0129] It should be noted that due to the use of multi-beam transmission, there are multiple PDCCH monitoring opportunities in one PO, and each PDCCH monitoring opportunity corresponds to a beam. Therefore, in the embodiment provided in the present application, the PDCCH monitoring opportunity in the PO corresponds to the SSB in the SS burst set, and the PDCCH monitoring opportunity in the PO also corresponds to the first DMRS.
[0130] Each or every several monitoring opportunities corresponds to an SSB and is used for multi-beam transmission of paging messages. Fig.14 As shown, the SS burst set includes multiple SSBs, and each SSB 141 corresponding to the first DMRS signal corresponds to a PDCCH monitoring opportunity 142 in the PO.
[0131] In a possible implementation, before receiving the energy-saving signal in step 710, the following steps may be further performed:
[0132] Step 701: Determine a time offset parameter, a minimum time interval, and a period of a synchronization signal block;
[0133] Step 702: Determine the reception time of the first reference signal based on the time offset parameter, the minimum time interval, and the period of the synchronization signal block.
[0134] Correspondingly, step 710 of receiving the energy-saving signal includes:
[0135] Based on the reception time of the first reference signal, a first reference signal is received.
[0136] Here, since the SS burst set is sent periodically, before the PO or PF of the terminal device arrives, there may be multiple periods of SS burst set sending. At this time, it is necessary to determine which SS burst sets carry the energy-saving signal.
[0137] In the embodiment provided in the present application, the monitoring time of the first reference signal can be determined by using the time offset parameter and the minimum time interval in combination with the period of the configured SS burst set (ie, the period of the SSB).
[0138] Here, the time offset parameter can be a value agreed upon in advance between the terminal device and the network device, or it can be configured by the network device through a system message, which is not limited in this embodiment of the present application.
[0139] The terminal device needs to perform operations such as device wake-up and initialization after wake-up before PF or PO is reached. Therefore, before the minimum time interval starts, the terminal device needs to receive a complete energy-saving signal. Within the minimum time interval before PF or PO is reached, the terminal device performs initialization operations after wake-up, so there is no need to monitor the energy-saving signal within the minimum time interval.
[0140] 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 (such as 15kHz) can use a shorter minimum time interval (such as value 1 in Table 1) for the terminal device with a faster initialization speed, while a longer minimum time interval (such as value 2 in Table 1) can be used for the terminal device with a slower initialization speed. Here, the unit of the minimum time interval is a slot.
[0141] Table 1
[0142]
[0143] In the embodiment provided in the present application, the monitoring timing of the first reference signal can be determined by a time offset parameter and a minimum time interval in combination with the period of the configured SS burst set. Fig.15 As shown, before the PF or PO arrives, the terminal device receives the first reference signal within a complete SSB burst set that meets the configured time offset parameters and minimum time interval.
[0144] 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.
[0145] Based on the above embodiments, the present application also provides an information processing method, which is applied to Figure 6 In the illustrated network device 610, the method includes:
[0146] Step 810: Send 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 method of the terminal device based on the energy-saving related information.
[0147] Here, the network device can send a first reference signal to the terminal device before sending a paging message to the terminal device, so that when the paging message arrives, the terminal device can determine whether to monitor the PDCCH to receive the paging message based on the energy-saving related information carried in the first reference signal.
[0148] In an embodiment of the present application, the network device carries the energy-saving related information in the first reference signal and sends it to the terminal device; in this way, the terminal device can determine the paging processing method of the terminal device based on the energy-saving related information; here, the reference signal is used to carry the energy-saving related information, which can reduce the energy consumption used in parsing the first reference signal and achieve the effect of power saving.
[0149] In a possible implementation, the first reference signal is generated in the same manner as a demodulation reference signal in a synchronization signal block.
[0150] That is to say, the first reference signal can be generated by reusing the PBCH DMRS method in the existing SSB, and the first reference signal is used as the energy-saving signal of the terminal device to carry the energy-saving related information of the terminal device.
[0151] 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 to indicate the lowest three bits of the SSB index, which identifies the position of the SSB in the SS burst set.
[0152] In order to maintain backward compatibility, the PBCH DMRS currently carried in the SSB cannot be used as an energy-saving signal to indicate other information. However, the PBCH DMRS generation method can be used to obtain the first reference signal, and the first reference signal can be used as the energy-saving indication information of the terminal device, so that the technical complexity of generating the first reference signal can be reduced.
[0153] In a possible implementation manner, the sequence length of the first reference signal is the same as or different from the sequence length of the demodulation reference signal.
[0154] In practical applications, the length of the PBCH DMRS in the 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 can 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 the embodiments of the present application.
[0155] In a possible implementation manner, the first reference signal includes multiple sequences; different first reference signal sequences carry different energy-saving related information.
[0156] Here, the first reference signal is generated in the same manner as the PBCH DMRS in the SSB, that is, the first reference signal can also include up to 8 different sequences. Different sequences can indicate that different energy-saving related information is carried.
[0157] In a possible implementation, the first reference signal and the synchronization signal block have a corresponding relationship; the corresponding relationship includes a quasi-co-address relationship.
[0158] In the embodiment provided in the present application, the time-frequency resources of the first reference signal correspond to the time-frequency resources of the synchronization signal block.
[0159] 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:
[0160] The frequency domain resource position of the first reference signal at least partially overlaps with the frequency domain resource position of the synchronization signal block, and the time domain resource position of the first reference signal does not overlap with the time domain resource position of the synchronization signal block.
[0161] 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:
[0162] The time domain resource position of the first reference signal at least partially overlaps with the time domain resource position of the synchronization signal block, and the frequency domain resource position of the first reference signal does not overlap with the frequency domain resource position of the synchronization signal block.
[0163] 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:
[0164] The orthogonal frequency division multiplexing OFDM symbol of the first reference signal is the same as the OFDM symbol occupied by the primary synchronization signal in the synchronization signal block, and the frequency domain resources of the first reference signal include the first subcarrier set and / or the second subcarrier set;
[0165] The first subcarrier set and the second subcarrier set do not overlap with the subcarrier set occupied by the primary synchronization signal.
[0166] In the embodiments provided in the present application, the network device may send an energy-saving signal on a time-frequency resource within a preset range of the SSB time-frequency resource. That is, the network device sends an energy-saving signal on a time-frequency resource near the SSB. In this way, before the arrival of PF or PO, the terminal device can detect the energy-saving signal near the SSB time-frequency resource location when detecting the SSB for time-frequency synchronization operation, thereby avoiding the extra power consumption caused by detecting the energy-saving signal alone and achieving the effect of power saving.
[0167] In this way, the energy-saving signal is carried near the time and frequency resource position of the SSB. When the terminal device detects the SSB for time and frequency synchronization operation, it can detect the energy-saving signal at the same time, thus avoiding the extra power consumption caused by detecting the energy-saving signal alone.
[0168] In the embodiment provided in the present application, before step 810 sends the energy-saving signal to the terminal device, the following steps may also be performed:
[0169] Step 801: Send configuration information to a terminal device; the configuration information includes a time offset parameter.
[0170] It is understandable that the network device can configure the time offset parameter for the terminal device, so that the terminal device can determine the reception time of the energy-saving signal based on the time offset parameter.
[0171] In a possible implementation manner, the configuration information may be carried by system information.
[0172] In the embodiment provided in the present application, the synchronization signal block is any one of the synchronization signal burst sets sent by the network device.

[0175] The first processing unit 1602 is used to determine the paging processing method of the terminal device based on the energy-saving related information.
[0176] In the embodiment provided in the present application, the first processing unit 1602 is used to determine that the terminal device monitors the PDCCH at a specific paging opportunity if the energy-saving related information indicates that the physical downlink control channel PDCCH is monitored at the specific paging opportunity; the specific paging opportunity is used to characterize the time period for the terminal device to detect the paging indication information; if the energy-saving related information indicates not to monitor the PDCCH at the specific paging opportunity, it is determined that the terminal device does not monitor the PDCCH at the specific paging opportunity.
