Description

Information transmission method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information transmission method and apparatus.

Background

In the prior art, research on an energy saving scheme in a Radio Resource Control (RRC) idle (idle) state is proposed, specifically including reduction of unnecessary Paging (Paging) reception. The detection of invalid Paging messages can be reduced by adopting Paging Early Indication (PEI) in an RRC idle state, so that the power consumption of the terminal is reduced. PEI indicates that the power consumption of the terminal can be reduced to a large extent, for example, 10% to 46% of the power consumption can be saved. The terminal receives the PEI before receiving the paging message, if the terminal is indicated to need to receive the subsequent paging message, the terminal continues to receive the paging message, otherwise, the terminal can enter a low power consumption or a dormant state, and therefore the power consumption of the terminal is reduced.

Detailed Description

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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

A method for indicating sub-group of terminals by PEI based on sequence is as follows: for N sub-groups, the base station designs N groups of sequences, which correspond to the N sub-groups one by one. Each group has two sequences, one sequence is used for indicating User Equipment (UE) to monitor a Paging Opportunity (PO), the other sequence is used for indicating the UE not to monitor the PO, and the base station sends N sequences corresponding to N sub-groups on a PEI transmission resource to indicate whether the UE in the N sub-groups monitors the PO. For example, the sequence Seq1-1 and the sequence Seq1-2 are used to indicate whether the UE in the sub-group 1 of the packet is to listen to the PO, respectively, the sequence Seq2-1 and the sequence Seq2-2 are used to indicate whether the UE in the sub-group 2 of the packet is to listen to the PO, respectively, and so on, the sequence Seq N-1 and the sequence Seq N-2 are used to indicate whether the UE in the sub-group N is to listen to the PO, respectively; for example, when there is UE in sub-group 1 to be paged, the base station needs to send Seq1-1, seq2-2, …, and SeqN-2 on the PEI sending resource, all UEs send a resource detection sequence in the PEI, and when a UE belonging to sub-group 1 detects Seq1-1, it is known that it needs to wake up to monitor PO at this time, and UEs belonging to other sub-groups sleep.

In addition to indicating sub-group paging, the base station also needs to indicate a terminal time-frequency tracking reference signal and/or a channel state information reference signal (TRS and/or CSI-RS) ₎ Whether the information can be obtained or not can be indicated through an indication signal, such as Seq _ TRS, when the terminal can obtain the TRS and/or the CSI-RS at the moment, the base station additionally transmits the Seq _ TRS indication terminal, and when the terminal cannot obtain the TRS and/or the CSI-RS at the moment, the base station does not transmit.

However, the above scheme for indicating sub-groups and TRSs and/or CSI-RS availability based on the sequence PEI has a disadvantage mainly in that the overhead of the base station is too large, specifically:

assuming that all UEs in the cell are divided into N sub-groups, there are N groups of sequences (sequences) corresponding to the N sub-groups; there are three cases of UE paging:

a.N no UE in sub-groups is paged, at this time, the base station sends N sequences on the PEI resource to indicate that the UE in all the N sub-groups does not monitor PO;

b. the paged UE is in the same sub-group, at the moment, the base station sends 1 sequence on the PEI resource to indicate that the UE in the sub-group monitors PO, and sends N-1 sequence to indicate that the UE in other N-1 sub-groups does not monitor PO;

c. the paged UE is in m sub-groups (m > = 2), at this time, the base station sends m sequences on the PEI resource to indicate the UE in the m sub-groups to monitor the PO, and sends N-m sequences to indicate the UE in other N-m sub-groups not to monitor the PO.

As shown above, no matter whether there is a UE paged in the N sub-groups or how the paged UE is distributed among the sub-groups, the base station needs to send N sequences on the PEI resource, and when the N value is large, this will bring a considerable power consumption overhead to the base station, and a large amount of power consumption of the base station is needed. Also, the base station needs to additionally transmit an indication signal to indicate the TRS and/or CSI-RS availability, which also increases the power consumption overhead of the base station.

In addition, the base station simultaneously sends N sequences on the PEI sending resource, and the UE needs to detect the corresponding sequences from the PEI when detecting the PEI. When the value of N is larger, it also means that more sequences are superimposed on the PEI transmission resource, and the interference between sequences is larger when the UE detects the sequences, which directly causes the degradation of UE sequence detection performance, and the increase of missed detection rate, resulting in the increase of unnecessary PO monitoring power consumption of the UE.

The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

The technical scheme provided by the embodiment of the application can be suitable for various systems, particularly 5G systems. For example, the applicable system may be a global system for mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) system, a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) system, a 5G NR system, and the like. These various systems include terminal devices and network devices.

The terminal device referred to in the embodiments of the present application may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or other processing device connected to a wireless modem. The names of the terminal devices may also be different in different systems, for example, in a 5G system, the terminal devices may be referred to as User Equipments (UEs). Wireless terminal devices, which may be mobile terminal devices such as mobile telephones (or "cellular" telephones) and computers having mobile terminal devices, e.g., mobile devices that may be portable, pocket, hand-held, computer-included, or vehicle-mounted, communicate voice and/or data with a radio access network via the RAN. Such as Personal Communication Service (PCS) phones, cordless phones, session Initiated Protocol (SIP) phones, wireless Local Loop (WLL) stations, personal Digital Assistants (PDAs), and the like. The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in this embodiment of the present application.

A base station may also be referred to as an access point, or a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network device may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiment of the present application may be a Base Transceiver Station (BTS) in a global system for mobile communications (GSM) or a Code Division Multiple Access (CDMA), may also be a network device (NodeB) in a Wideband Code Division Multiple Access (WCDMA), may also be an evolved network device (eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station in a 5G network architecture (next generation system), or may also be a home evolved node B (HeNB), a relay node (HeNB), a home base station (femto), a pico base station (pico), and the like, which are not limited in the embodiment of the present application.

Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.

At Active Time (Active Time), the base station configures various Reference signals RS (Reference Signal) for the UE, which may include CSI-RS for channel tracking, CSI-RS for mobility measurement, and CSI-RS for channel measurement reporting. The existing NR standard cannot provide the RS for the UE in Idle (Idle) or deactivated (Inactive) mode, and the UE cannot improve system performance and reduce power consumption by using the RS. The 3GPP conference currently decides to provide CSI-RS and/or TRS (Tracking Reference Signal) (TRS is one of CSI-RS) for UE in Idle mode or Inactive mode for time and frequency channel Tracking, and the TRS and/or CSI-RS are configured by SIB (System Information Block) signaling, and the TRS and/or CSI-RS may be shared with connected UE, or it may be understood that the TRS and/or CSI-RS used by the base station for connected transmission is signaled to UE in Idle mode (mode) through SIB signaling.

Because the TRS and/or CSI-RS configured by the base station for the connection state may be transmitted along with the connection state UE, so that the TRS and/or CSI-RS transmission is deactivated quickly, and thus RS resources configured by the base station for idle mode UE may not have RS transmission, it is required to indicate whether the TRS and/or CSI-RS resources configured by the base station for idle/inactive mode UE have TRS and/or CSI-RS transmission, that is, it is required to indicate availability (availability) of the TRS and/or CSI-RS at the TRS and/or CSI-RS occase, so as to avoid the UE performing RS blind detection operation. At present, in the discussion of the UE energy saving topic of Rel-17, the following problems are mainly addressed:

1. the PEI is specifically PEI based on downlink control information (DCI-based) or PEI based on sequence-based (sequence-based);

2. whether sub-grouping is supported, if so, the sub-grouping is specifically carried by PEI, or carried by paging DCI of scheduling paging messages;

3. there are two hypotheses for the meaning of PEI and the interpretation of the absence of PEI detected by the UE:

behavior a, if the group (sub-group) where the UE is located (or directly the group) where the UE is located) is paged, the PEI instructs the UE to monitor the PO; if the UE does not detect PEI in all PEI opportunities corresponding to the PO, the UE does not monitor the PO.

PEI indicates whether the UE should monitor the PO; if the UE does not detect PEI in all PEI opportunities corresponding to a PO, the UE needs to detect the PO.

4. Whether the RRC idle/inactive UE can obtain the TRS and/or the CSI-RS is indicated by the PEI or the paging DCI.

In view of the above problems, embodiments of the present application mainly provide a technical solution for indicating a terminal group (sub-group) paging by sequence-based (sequence-based) PEI under the assumption of Behavior b, and can indicate availability of a UE in an RRC idle or inactive mode to a preset reference signal (e.g., including a TRS and/or a CSI-RS).

On the network side, the information transmission method provided by the embodiment of the application comprises the following steps:

determining information currently indicated to a terminal, and sending a preset sequence set on a preset resource for indicating the information;

the sequence set comprises one or more preset sequences, and the information comprises paging information of terminal grouping and/or indication information of whether the terminal can obtain the TRS and/or the CSI-RS.

That is to say, in the embodiment of the present application, a terminal is agreed in advance or notified by a network side, and different sequences, information used for indication by the different sequences, a group to which the terminal belongs, a correspondence between the group and the sequence of the terminal, and the like are performed, so that in an information transmission process, only the sequences are transmitted, and paging information of the terminal group and/or an indication whether the terminal can obtain a TRS and/or a CSI-RS can be implemented. Therefore, the network side overhead can be further saved, the power consumption increase caused by unnecessary PO monitoring of the terminal can be avoided, and the resources are saved.

The technical solutions provided in the embodiments of the present application are respectively introduced from two aspects of indicating only paging information of terminal groups and further indicating whether the terminal can obtain indication information of the TRS and/or the CSI-RS, and naturally only indicating whether the terminal can obtain the indication information of the TRS and/or the CSI-RS is the same, and therefore, the details are not repeated.

In a first aspect: the method for indicating paging information of terminal grouping based on sequence signals provided by the embodiment of the application comprises the following steps:

the base station sends a preset sequence set on preset resources, and the preset sequence set is used for indicating information which needs to be indicated to a terminal at present;

the sequence set comprises one or more preset sequences, the information comprises paging information of terminal grouping, the paging information is whether a terminal in a sub-group is paged or not, if the terminal in the sub-group is paged, the terminal in the sub-group monitors paging, and if the terminal is not paged, the terminal in the sub-group does not monitor paging.

Correspondingly, the terminal receives the sequence set on the preset resource;

and determining the information indicated by the network side according to the received sequence set, if the sub-group to which the terminal belongs is paged, monitoring paging by the terminal, and if the terminal is not paged, not monitoring paging by the terminal.

The sequence set comprises one or more preset sequences;

the first sequence may send a plurality of different first sequences, where different first sequences correspond to different sub-groups and are used to indicate paging information of the corresponding sub-groups (the paging information is paged or not paged);

the second and third sequences are used for indicating paging information of all sub-groups, and both the second and third sequences send at most one, for example, when all terminals in a cell are not paged, the sequence set comprises a preset second sequence used for indicating that all terminal groups do not monitor paging; when all terminals in the cell are paged, the sequence set comprises a preset third sequence for indicating that all terminal groups monitor paging.

The first sequence, the second sequence and the third sequence are all different sequences.

That is, one first sequence indicates that the UE in one sub-group corresponding to the first sequence monitors paging, a second sequence indicates that the UE in all sub-groups does not monitor paging, and a third sequence indicates that the UE in all sub-groups monitors paging.

Specific base station and terminal behaviors:

base station side behavior:

the base station determines information currently indicated to the terminal, thereby determining a sequence set. The sequence set comprises three sequences, namely a first sequence, a second sequence and a third sequence, and what sequence is included in the specific sequence set depends on the information needing to be indicated.

Regarding the first sequence, if transmission is required, the base station may determine the first sequence to be transmitted based on the sub-group to which the UE belongs and the correspondence between the first sequence and the sub-groups.

In the embodiment of the application, all UEs in a cell are divided into N sub-groups, a base station determines a one-to-one correspondence relationship between N first sequences and the N sub-groups, the N first sequences are respectively used for indicating paging information corresponding to the N sub-groups, for example, seq _1 is used for indicating that paging exists in sub-group _1, seq _2 is used for indicating that paging exists in sub-group _2, and so on, and Seq _ N is used for indicating that paging exists in sub-group _ N. Seq _1 to Seq _ N are all the first sequences.

In the embodiment of the application, the base station may notify sub-group information, sequence information, a correspondence between a terminal group and a sequence, and the like through configuration signaling (e.g., high-level signaling); wherein the information of the sequence includes, for example, an identification of the sequence, information indicated by the sequence, and the like. The terminal can know the sub-group to which the terminal belongs, the information indicated by the sequence sent by the network side, the corresponding relation between the sub-group and the first sequence and the like through the notification.

Or, in the embodiment of the present application, an agreed preset rule may also be implemented at the network side and the terminal side, and the preset rule may be used to determine the terminal grouping information, the sequence information, the correspondence between the terminal grouping and the sequence, and the like.

The sub-group information, such as a sub-group ID, indicates to which sub-group the UE belongs.

The preset rule can be used for calculating the sub-group to which the UE belongs and the corresponding first sequence, and can also be used for calculating the second sequence and the third sequence.

For example, the sub-group ID to which the terminal belongs is obtained by the formula sub-group _ ID = UE _ ID mod N, and the initial IDs of the second sequence and the third sequence are agreed in advance with the sub-group _ ID as the initial ID of the first sequence.

In the embodiment of the present application, a method for determining a preset resource by a base station is the prior art, and related descriptions are subsequently performed in the embodiment. For the base station side and the terminal side, the preset resources are the same, the base station transmits on the resources, and the terminal receives on the resources, so that both the base station and the terminal need to determine the preset resources.

After the preset resources are determined, the base station sends a sequence indication to indicate whether the UE belonging to each sub-group monitors paging or not on the preset resources according to the paging information of all the current UE in the cell. For example:

the UE in the cell is divided into N sub-groups, and when the UE belonging to the N sub-groups in the cell is not paged, the base station sends a second sequence on a preset resource;

when the paged UEs in the cell all belong to sub-group _ x, the base station sends a first sequence (such as Seq _ x) and a second sequence corresponding to the sub-group _ x on preset resources;

and when the paged UE in the cell belongs to m sub-groups (m > = 2), the base station sends a third sequence on the preset resource. That is, when the terminals to be paged in the cell belong to different terminal groups, that is, the terminals to be paged are not all in one sub-group, the third sequence is sent to indicate that all terminals monitor paging.

Terminal side behavior:

and the terminal determines the sub-group to which the terminal belongs and the corresponding first sequence, and determines the second sequence and the third sequence according to the signaling or through a preset rule.

The terminal determines a preset resource, receives a sequence on the preset resource, and performs sequence detection, specifically for example:

when the terminal detects a first sequence corresponding to the sub-group to which the terminal belongs and does not detect a second sequence, the terminal monitors paging; i.e. the first and second sequences are received simultaneously, the second sequence is ignored and only the first sequence is considered.

When the terminal detects the second sequence and does not detect the first sequence corresponding to the sub-group to which the terminal belongs, the terminal sleeps;

when the terminal detects the second sequence and the first sequence corresponding to the sub-group to which the terminal belongs at the same time, the terminal monitors paging;

when the terminal detects the third sequence, the terminal listens for pages.

In a second aspect: the base station transmits one or more sequences in the sequence set on preset resources, and indicates sub-group paging information and availability (that is, availability or unavailability) of CSI-RS (for example, including TRS).

Accordingly, the terminal receives one or more sequences in the sequence set on preset resources, thereby determining the availability of paging information and TRS and/or CSI-RS of the terminal.

In the sequence set, for example, five sequences including a first sequence, a second sequence, a third sequence, a fourth sequence and a fifth sequence, what sequence is included in the sequence set is specifically sent, which is determined according to the actual situation;

the first sequence may send multiple, different first sequences correspond to different sub-groups, and are used to indicate paging information of the corresponding sub-groups;

the second sequence, the third sequence, the fourth sequence, and the fifth sequence may be used to indicate availability of paging information and TRS (for example, TRS, all CSI-RS are applicable), where the second sequence, the third sequence, the fourth sequence, and the fifth sequence are all transmitted at most one, that is, each sequence of the four sequences is not transmitted at a time, because there is no situation that different terminal groups correspond to different second sequence, third sequence, fourth sequence, or fifth sequence, unlike the first sequence.

The indication method 1: the second sequence and the third sequence are respectively used for indicating whether sub-group exists or not and whether paging exists, and the fourth sequence and the fifth sequence are respectively used for indicating whether the current TRS of the UE is yes or not and whether the current TRS can be obtained or not.

Namely:

the first condition is as follows: when all terminals in the cell are not paged, the sequence set comprises a preset second sequence used for indicating that all terminal groups do not monitor paging.

Case two: when all terminals in the cell are paged, the sequence set comprises a preset third sequence for indicating that all terminal groups monitor paging.

Case three: when all the terminal groups can obtain the TRS, the sequence set includes a preset fourth sequence for indicating that all the terminal groups can obtain the TRS.

Case four: when all the terminal groups cannot obtain the TRS, the sequence set includes a preset fifth sequence for indicating that all the terminal groups cannot obtain the TRS.

The above case one, case two, and case three, case four can be combined two by two respectively, and two sequences are sent simultaneously in the preset resource. For example: and simultaneously transmitting the third sequence and the fourth sequence in preset resources, or simultaneously transmitting the third sequence and the fifth sequence in the preset resources, and the like.

The indication method 2 comprises the following steps: the second sequence, the third sequence, the fourth sequence and the fifth sequence are respectively used for indicating that all sub-groups are paged and TRS can be obtained, all sub-groups are paged and TRS cannot be obtained, all sub-groups are not paged and TRS can be obtained, and all sub-groups are not paged and TRS cannot be obtained.

That is to say:

if all terminal groups do not monitor paging and all terminal groups cannot acquire the TRS, the sequence set includes a preset second sequence for indicating that all terminal groups do not monitor paging and all terminal groups cannot acquire the TRS.

If all terminal groups monitor paging and all terminal groups can obtain TRS, the sequence set includes a preset third sequence for indicating that all terminal groups monitor paging and all terminal groups can obtain TRS.

If all terminal groups do not monitor paging and all terminal groups can obtain TRS, the sequence set includes a preset fourth sequence for indicating that all terminal groups do not monitor paging and all terminal groups can obtain TRS.

If all terminal groups monitor paging and all terminal groups cannot acquire the TRS, the sequence set includes a preset fifth sequence for indicating that all terminal groups monitor paging and all terminal groups cannot acquire the TRS.

Specific base station and terminal behaviors:

base station side behavior:

the base station determines information currently indicated to the terminal, thereby determining a sequence set. The sequence set comprises five sequences, namely a first sequence, a second sequence, a third sequence, a fourth sequence and a fifth sequence, and what sequence is included in the specific sequence set depends on the information needing to be indicated.

In the embodiment of the application, all UEs in a cell are divided into N sub-groups, a base station determines a one-to-one correspondence relationship between N first sequences and the N sub-groups, the N first sequences are respectively used for indicating paging information corresponding to the N sub-groups, for example, seq _1 is used for indicating that paging exists in the sub-groups _1, seq _2 is used for indicating that paging exists in the sub-groups _2, and so on, and Seq _ N is used for indicating that paging exists in the sub-groups _ N. Seq _1 to Seq _ N are all the first sequences.

The preset rule can be used for calculating the sub-group to which the UE belongs and the corresponding first sequence, and can also be used for calculating a second sequence, a third sequence, a fourth sequence and a fifth sequence.

For example, the sub-group ID to which the terminal belongs may be obtained by the formula sub-group _ ID = UE _ ID mod N, the sub-group _ ID may be used as the initial ID of the first sequence, and the initial IDs of the second, third, fourth, and fifth sequences may be agreed in advance.

In the embodiment of the present application, a method for determining preset resources by a base station is described in the embodiment. For the base station side and the terminal side, the preset resources are the same, the base station transmits on the resources, and the terminal receives on the resources, so that both the base station and the terminal need to determine the preset resources.

After the preset resources are determined, the base station sends a sequence indicating whether the UE belonging to each sub-group monitors paging or not on the preset resources according to the paging information of all the current UE. For example:

for indication method 1, one or more sequences may be sent on preset resources:

when the UE paged in the cell belongs to sub-group _ x, the base station sends a first sequence corresponding to the sub-group _ x and a second sequence in a preset resource;

and when the paged UE in the cell belongs to m sub-groups (m > = 2), the base station sends a third sequence on the preset resource.

At this time, the base station transmits the fourth or fifth sequence on the preset resource, or the base station transmits or does not transmit the fourth sequence on the preset resource according to whether the TRS is available.

And when the UE belonging to the N sub-groups in the cell is not paged, the base station sends a second sequence in the preset resource. At this time, because the UE does not monitor paging, it is not necessary to use the TRS for time-frequency synchronization, and the base station may also transmit a fourth or fifth sequence in the preset resource to indicate whether the TRS is available or not while transmitting the second sequence.

For indication method 2, one or more sequences may be sent on the preset resources:

when the paged UE in the cell belongs to sub-group _ x, if the current TRS can be obtained, the base station sends a first sequence corresponding to the sub-group _ x on a preset resource and simultaneously sends a fourth sequence; if the current TRS can not be obtained, the base station sends a first sequence (such as Seq _ x) corresponding to the sub-group _ x on a preset resource and simultaneously sends a fifth sequence;

when the UE belonging to the N sub-groups in the cell is not paged, if the TRS can be obtained, the base station sends a fourth sequence on a preset resource; if the TRS can not be obtained, the base station sends a fifth sequence on preset resources;

when the paged UE in the cell belongs to m sub-groups (m > = 2), if the TRS can be obtained, the base station sends a second sequence on a preset resource; and if the TRS can not be obtained, the base station transmits a third sequence on the preset resource.

Terminal side behavior:

and the terminal calculates and determines the sub-group to which the terminal belongs and the corresponding first sequence according to the signaling or through a preset rule, and determines a second sequence, a third sequence, a fourth sequence and a fifth sequence.

The terminal determines a preset resource, receives a sequence on the preset resource, and performs sequence detection, for example:

for the indication method 1:

when the terminal detects a first sequence corresponding to the sub-group to which the terminal belongs and does not detect a second sequence, the terminal monitors paging;

when the terminal detects the second sequence and the first sequence corresponding to the sub-group to which the terminal belongs, the terminal monitors paging;

when the terminal detects the third sequence, the terminal listens for pages.

When the terminal detects the fourth sequence, the terminal is indicated to be capable of obtaining the TRS sent by the base station;

when the terminal detects the fifth sequence or does not detect the fourth sequence, it indicates that the terminal cannot obtain the TRS transmitted by the base station.

For the indication method 2:

if the terminal detects the first sequence corresponding to the sub-group to which the terminal belongs and detects the fourth sequence, the terminal monitors paging and can obtain a TRS sent by the base station;

if the terminal detects the first sequence corresponding to the sub-group to which the terminal belongs and detects the fifth sequence, the terminal monitors paging and cannot obtain the TRS sent by the base station;

if the terminal does not detect the first sequence but detects the fourth sequence, the terminal does not monitor paging but can obtain the TRS sent by the base station;

if the terminal does not detect the first sequence and detects the fifth sequence, the terminal does not monitor paging and cannot obtain the TRS sent by the base station;

if the terminal detects the second sequence, the terminal monitors paging and can obtain a TRS sent by the base station;

if the terminal detects the third sequence, the terminal monitors paging but cannot obtain the TRS transmitted by the base station.

Examples of several specific embodiments are given below:

example 1: and the base station/the terminal sends/receives one or more sequences in the sequence set on preset resources to indicate sub-group paging information.

A base station determines a sub-group and a sequence set of a terminal, wherein the sequence set comprises a first sequence, a second sequence and a third sequence; the first sequence corresponds to the sub-group.

Step 2: the base station determines preset resources. For PEI, the predetermined resource is the location of the PEI resource. The PEI resource location and the PO resource location may be bound, for example, the PEI resource location is at a number of time slots before the PO, and the base station further determines the PEI resource location by determining the resource location of the PO; the PEI resource location may also be bound to the SSB location, e.g., the PEI resource location is at several time slots after the SSB, and the base station further determines the PEI resource location by determining the resource location of the SSB; or other PEI resource location determination methods.

And 3, step 3: the base station determines which sequence/sequences to send according to the sub-group paging information and sends the sequences on a preset resource to indicate whether the UE monitors paging in a corresponding PO, and specifically, what sequence/sequences to send under which paging information is as follows:

when the UE belonging to the N sub-groups in the cell is not paged, the base station sends a second sequence;

when the paged UEs in the cell all belong to the same sub-group, the base station sends a first sequence (such as Seq _ x) and a second sequence corresponding to the sub-group _ x;

when the paged UE in the cell belongs to m sub-groups (m > = 2), the base station transmits a third sequence.

And 4, step 4: and the terminal determines the preset resources. For PEI, the predetermined resource is the location of the PEI resource. If the PEI resource position is bound with the PO resource position, the terminal calculates to obtain the PO resource position according to a formula, and the PEI resource position is determined according to the corresponding relation of the PO and the PEI resource position; if the PEI resource position is bound with the SSB, the terminal determines the PEI resource position according to the resource position of the received SSB; or other PEI resource location determination methods. The terminal performs sequence receiving detection on the position of the PEI resource, specifically:

when the terminal detects the first sequence corresponding to the sub-group to which the terminal belongs, the terminal does not detect other sequences any more, and monitors paging in the corresponding PO;

when the terminal detects the second sequence, if the first sequence corresponding to the sub-group to which the terminal belongs is not detected, the terminal sleeps;

when the terminal detects the third sequence, the terminal does not detect other sequences any more, and monitors paging at the corresponding PO.

For PEI, the UE obeys Behavior b, that is, the UE does not detect PEI and then monitors the corresponding PO, so the base station needs to send PEI on a PEI resource location to indicate whether the UE monitors PO (this is equivalent to that PEI is always on signal) whether the UE is paged or not. If the paging information of N sub-groups indicated by N sequences is directly sent, considerable overhead is brought to the base station. In the prior art, a better solution to the problem of Behavior b is not provided. By applying the scheme provided by the embodiment of the application, the paging information of all sub-groups can be indicated through one or the combination of two of the three sequences with different indication functions, namely the first sequence, the second sequence and the third sequence. The benefits of the invention are analyzed in detail below:

the base station overhead is small. According to the foregoing description of the steps of the present invention, with the method proposed in the embodiment of the present application, the base station only needs to transmit at most two sequences (the first sequence and the second sequence) on the PEI transmission resource. According to the discussion of the 3GPP Rel-17 energy saving issue, the probability of PO being paged is about 10%, which means that the base station only needs to transmit one sequence on the PEI transmission resource for about 90% of the time, which can greatly reduce the overhead of the base station and save the base station operation power.

The influence on the terminal monitoring paging false alarm rate is small. It is derived from the mathematical formula that when the PO paging rate is 10%, the probability that multiple (more than one) sub-groups are awakened at the same time is 10% -CN1 x Y (1-Y) ^ (N-1), where Y is the probability that one sub-group is awakened (calculated by the formula: 1- (1-Y) ^ N = 10%), and N is the number of sub-groups. As can be seen from the mathematical probability analysis, compared with the case that only one sub-group is awakened, the probability that a plurality of sub-groups are awakened at the same time is very small, and as the number of the sub-groups which are awakened increases, the probability further decreases. Therefore, in the embodiment of the present application, the third sequence is used to indicate the mode that all sub-group UEs monitor the PO, and the influence on the paging false alarm rate monitored by the UE is small.

And the detection performance of the terminal PEI is good. According to the aforementioned description of the steps of the present invention, by using the method proposed in the embodiment of the present application, at most two sequences exist at the position where the PEI sends the resource. Compared with the condition that N (N > 2) sequences exist in the PEI sending resource position, the method and the device are more beneficial to the sequence detection performance of the terminal and reduce the PEI omission factor. In addition, the embodiment of the application is also more beneficial to terminal energy saving from the viewpoint of reducing unnecessary PO monitoring caused by missing PEI detection of the terminal.

Example 2: a base station/terminal sends/receives one or more sequences in a sequence set on a preset resource to indicate sub-group paging information and TRS and/or CSI-RS availability, namely a method 1.

Step 2: the base station determines preset resources. For PEI, the predetermined resource is the location of the PEI resource. The PEI resource location and the PO resource location may be bound, for example, the PEI resource location is at a plurality of time slots before PO, and the base station further determines the PEI resource location by determining the PO resource location; the PEI resource location may also be bound to the SSB resource location, e.g., the PEI resource location is at a number of time slots after the SSB resource location, and the base station further determines the PEI resource location by determining the SSB resource location; or other PEI resource location determination methods.

And step 3: the base station determines what sequence/sequences to transmit according to the paging information of sub-groups and the availability of the TRS and/or CSI-RS and transmits the sequences on a preset resource to indicate whether the UE monitors paging in a corresponding PO and whether the TRS and/or CSI-RS is available, and specifically, what sequence/sequences to transmit under what conditions is as follows:

when the paged UE in the cell belongs to sub-group _ x and TRS and/or CSI-RS can be obtained, the base station sends a first sequence, a second sequence and a fourth sequence corresponding to the sub-group _ x in a preset resource; when the paged UE in the cell belongs to sub-group _ x and TRS and/or CSI-RS cannot be acquired, the base station sends a first sequence, a second sequence and a fifth sequence corresponding to the sub-group _ x in a preset resource;

when the paged UE in the cell belongs to m sub-groups (m > = 2) and the TRS and/or the CSI-RS can be obtained, the base station sends a third sequence and a fourth sequence in preset resources; when the paged UE in the cell belongs to m sub-groups (m > = 2), the TRS and/or the CSI-RS cannot be obtained, and the base station transmits the third sequence and the fifth sequence on preset resources.

And when the UE belonging to the N sub-groups in the cell is not paged, the base station sends a second sequence in the preset resource. At this time, since the UE does not monitor paging, it is not necessary to use the TRS for time-frequency synchronization, and the base station may transmit the fourth/fifth sequence indicating whether the TRS is available or not at the same time in the preset resource, or may not transmit the TRS.

And 4, step 4: and the terminal determines the preset resources. For PEI, the predetermined resource is the location of the PEI resource. If the PEI resource position is bound with the PO, the terminal calculates the position of the PO according to a formula, and the PEI resource position is determined according to the corresponding relation of the PO and the PEI resource position; if the PEI resource position is bound with the SSB, the terminal determines the PEI resource position according to the resource position of the received SSB; or other PEI resource location determination methods. The terminal performs sequence receiving detection on the position of the PEI resource, specifically:

when the terminal detects a first sequence corresponding to the sub-group to which the terminal belongs, the terminal monitors paging in the corresponding PO;

when the terminal detects the third sequence, the terminal monitors paging in the corresponding PO;

when the terminal detects the fourth sequence, the terminal can obtain a TRS and/or a CSI-RS sent by the base station;

when the terminal detects the fifth sequence, the terminal cannot obtain the TRS and/or CSI-RS transmitted by the base station.

By applying the scheme provided by the embodiment of the application, the paging information and the TRS availability of all sub-groups can be indicated through the combination of one or more sequences of five sequences with different indication functions, namely the first sequence, the second sequence, the third sequence, the fourth sequence and the fifth sequence. The benefits of embodiment 1 also apply to this embodiment. Compared with embodiment 1, in this embodiment, two sequences are added in the sequence set, which can indicate the availability of the terminal TRS and/or CSI-RS, and the base station transmits three sequences at most in the preset resource.

Embodiment 3 a base station/terminal transmits/receives one or more sequences in a sequence set on a preset resource to indicate sub-group paging information and TRS and/or CSI-RS availability-indicating method 2.

Step 2: the base station determines preset resources. For PEI, the predetermined resource is the location of the PEI resource. The PEI resource location and the PO resource location may be bound, for example, the PEI resource location is at a plurality of time slots before the PO, and the base station further determines the PEI resource location by determining the resource location of the PO; the PEI resource location may also be bound to the SSB location, e.g., the PEI resource location is at several time slots after the SSB, and the base station further determines the PEI resource location by determining the resource location of the SSB; or other PEI resource location determination methods.

when the paged UE in the cell belongs to sub-group _ x and TRS and/or CSI-RS can be obtained, the base station sends a first sequence and a fourth sequence corresponding to the sub-group _ x in preset resources; when the paged UE in the cell belongs to sub-group _ x and TRS and/or CSI-RS cannot be acquired, the base station sends a first sequence and a fifth sequence corresponding to the sub-group _ x in preset resources;

when the paged UE in the cell belongs to m sub-groups (m > = 2) and the TRS can be obtained, the base station sends a second sequence in a preset resource; when the paged UE in the cell belongs to m sub-groups (m > = 2), the TRS and/or the CSI-RS cannot obtain the TRS and/or the CSI-RS, and the base station transmits the third sequence on the preset resource.

When the UE belonging to the N sub-groups in the cell is not paged and the TRS and/or the CSI-RS can be obtained, the base station sends a fourth sequence on a preset resource; and when the UE belonging to the N sub-groups in the cell is not paged and the TRS and/or the CSI-RS cannot be obtained, the base station sends a fifth sequence on preset resources.

And 4, step 4: and the terminal determines the preset resources. For PEI, if the position of the PEI resource is bound with PO, the terminal calculates the position of the PO according to a formula, and the position of the PEI resource is determined according to the corresponding relation of the positions of the PO and the PEI resource; if the PEI resource position is bound with the SSB, the terminal determines the PEI resource position according to the resource position of the received SSB; or other PEI resource location determination methods. The terminal performs sequence receiving detection on preset resources, specifically:

when the terminal detects a first sequence corresponding to the sub-group to which the terminal belongs, the terminal monitors paging in the corresponding PO; meanwhile, if the terminal detects the fourth sequence on the preset resource, the terminal can obtain the TRS and/or the CSI-RS sent by the base station, and if the terminal detects the fifth sequence on the preset resource, the terminal cannot obtain the TRS and/or the CSI-RS sent by the base station.

When the terminal does not detect the first sequence corresponding to the sub-group to which the terminal belongs, if the terminal detects the fourth sequence, the terminal sleeps to obtain the TRS and/or the CSI-RS sent by the base station; if the terminal detects the fifth sequence, the terminal is asleep and cannot acquire the TRS and/or CSI-RS sent by the base station.

If the terminal detects the second sequence, the terminal monitors paging in the corresponding PO, and can obtain the TRS sent by the base station.

If the terminal detects the third sequence, the terminal monitors paging at the corresponding PO and cannot obtain the TRS sent by the base station.

By applying the scheme provided by the embodiment of the application, the paging information and the TRS availability of all sub-groups can be indicated through the combination of one or more sequences of five sequences with different indication functions, namely the first sequence, the second sequence, the third sequence, the fourth sequence and the fifth sequence. The benefits of embodiment 2 also apply to this embodiment. Compared with embodiment 2, the base station using this embodiment transmits two sequences at most on the preset resource.

To sum up, the embodiment of the present application may indicate paging information of all sub-groups in a cell by sending fewer sequences, and has the following specific advantages:

the base station overhead is small. By adopting the method provided by the embodiment of the application, the base station only needs to send two/three sequences on PEI sending resources at most. According to the discussion of the 3GPP Rel-17 energy saving issue, the probability of PO being paged is about 10%, which means that the base station only needs to transmit one sequence on the PEI transmission resource for about 90% of the time, which can greatly reduce the overhead of the base station and save the base station operation power.

The influence on the terminal paging false alarm rate is small. It is derived from the mathematical formula that when the PO paging rate is 10%, the probability that multiple (more than one) sub-groups are awakened simultaneously is 10% -CN 1Y (1-Y) ^ (N-1), where Y is the probability that one sub-group is awakened and N is the number of sub-groups. As can be seen from the mathematical probability analysis, compared with the case that only one sub-group is awakened, the probability that a plurality of sub-groups are awakened at the same time is very small, and as the number of the sub-groups which are awakened increases, the probability further decreases. Therefore, in the embodiment of the present application, a mode that one sequence is used to indicate all sub-group UEs to monitor the PO is adopted, and the UE paging false alarm rate is less affected.

And the detection performance of the terminal PEI is good. According to the above-mentioned description of the steps of the present invention, by using the method proposed in the embodiment of the present application, at most two sequence signals exist at the position of the PEI resource. Compared with the detection of N (N is sub-groups), the method and the device are more beneficial to the sequence detection performance of the terminal and reduce the missing rate of the PEI. In addition, the embodiment of the application is also more beneficial to terminal energy saving from the viewpoint of reducing unnecessary PO monitoring caused by missing PEI detection of the terminal.

The embodiment of the application can also indicate the availability of paging information and TRS and/or CSI-RS of all sub-groups in the cell by sending fewer sequences.
