Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to an information transmission method and device. BACKGROUND

[0002] In the prior art, research on energy saving schemes for a radio resource control (RRC) idle state is proposed, and specifically includes reducing unnecessary paging reception. The use of paging early indication (PEI) in the RRC idle state can reduce the detection of invalid paging messages, thereby reducing the power consumption of a terminal. PEI indication can greatly reduce the power consumption of a terminal, for example, saving 10% to 46% of power consumption. Before receiving a paging message, a terminal first receives PEI. If the terminal is instructed to receive a subsequent paging message, the terminal continues to receive the paging message, otherwise, the terminal can enter a low-power or sleep state, thereby reducing the power consumption of the terminal.

[0102] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort belong to the scope of protection of the present application.

[0103] A sequence-based PEI method for indicating terminal sub-groups is that for N sub-groups, the base station designs N groups of sequences, one-to-one corresponding to the N sub-groups. Each group has two sequences, one sequence for indicating that the user equipment (UE) monitors the paging occasion (PO), and the other sequence for indicating that the UE does not monitor the PO. The base station sends N sequences corresponding to the N sub-groups on the PEI sending resource to indicate whether the UEs in the N sub-groups monitor the PO. For example, sequence Seq1-1 and sequence Seq1-2 are used to indicate whether the UEs in sub-group 1 monitor the PO, respectively, Seq2-1 and Seq2-2 are used to indicate whether the UEs in sub-group 2 monitor the PO, respectively, and so on, SeqN-1 and SeqN-2 are used to indicate whether the UEs in sub-group N monitor the PO, respectively; for example, when there is a UE in sub-group 1 that is paged, the base station needs to send Seq1-1 and Seq2-2,..., SeqN-2 on the PEI sending resource. All UEs detect the sequences on the PEI sending resource, and the UEs belonging to sub-group 1 detect Seq1-1, and thus know that they need to wake up to monitor the PO at this time, and the UEs belonging to other sub-groups sleep.

[0104] In addition to indicating sub-group paging, the base station also needs to indicate terminal time-frequency tracking reference signals and / or channel state information reference signals (TRS and / or CSI-RS ) Whether it can be obtained can be indicated by an indication signal such as Seq_trs. When the terminal can obtain the TRS and / or CSI-RS at this time, the base station additionally sends Seq_trs to indicate the terminal, and when the terminal cannot obtain the TRS and / or CSI-RS at this time, the base station does not send.

[0105] However, the main disadvantage of the above sequence-based PEI method for indicating sub-groups and TRS and / or CSI-RS obtainability is that the base station has a large overhead, specifically:

[0106] Suppose that all UEs in the cell are divided into N sub-groups, and N groups of sequences correspond to the N sub-groups; there are three cases of UE paging:

[0107] a. None of the N sub-groups has a UE that is paged, and at this time the base station sends N sequences on the PEI resource to indicate that the UEs in all N sub-groups do not monitor the PO;

[0108] b. The paged UE is in the same sub-group, at this time the base station sends 1 sequence on the PEI resource to indicate the UE in the sub-group to monitor the PO, and sends N-1 sequences to indicate the UE in the other N-1 sub-groups not to monitor the PO;

[0109] 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 the other N-m sub-groups not to monitor the PO.

[0110] As shown above, no matter whether there is UE paged in the N sub-groups or how the paged UE is distributed in the sub-groups, the base station needs to send N sequences on the PEI resource, when the value of N is large, this will bring considerable power consumption overhead to the base station, and a large amount of base station power consumption is needed. In addition, the base station needs to send an additional indication signal to indicate the TRS and / or CSI-RS obtainability, which also increases the power consumption overhead of the base station.

[0111] In addition, the base station simultaneously sends N sequences on the PEI sending resource, and the UE needs to detect the sequence corresponding to it when detecting the PEI. When the value of N is large, it also means that there are more sequences superimposed on the PEI sending resource at this time, and the interference between the sequences when the UE detects the sequence is large, which will directly cause the UE sequence detection performance to decline, the missed detection rate to rise, and the unnecessary PO monitoring power consumption of the UE to increase.

[0112] Embodiments of the present application provide a kind of information transmission method and device, to further reduce network side overhead, while avoiding the power consumption increase caused by unnecessary PO monitoring of terminal, save resources.

[0113] Among them, method and device are based on the same application concept, since the principles of method and device to solve problems are similar, therefore the implementation of device and method can be mutually referred to, and the repeated place is not repeated.

[0114] The technical solutions provided by the embodiments of the present application can be applied to various systems, especially 5G systems. For example, the applicable systems can be a global system of 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 system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G system, and a 5G NR system, etc. The various systems all include terminal devices and network devices.

[0115] The terminal device to which the embodiments of the present application relate can refer to a device that provides voice and / or data connectivity to a user, a handheld device having a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device can also be different, for example, in the 5G system, the terminal device can be called user equipment (UE). The wireless terminal device can communicate with one or more core networks through the RAN, and the wireless terminal device can be a mobile terminal device, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal device, for example, it can be a portable, pocket, handheld, computer built-in or vehicle-mounted mobile device, which exchanges language and / or data with the wireless access network. For example, 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 can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, which is not limited in the embodiments of the present application.

[0116] The network device related to the embodiments of the present application can be a base station, which can include multiple cells. According to different application occasions, the base station can also be referred to as an access point, or can refer to a device in an access network that communicates with a wireless terminal device through one or more sectors over an air interface, or other names. The network device can be used to convert the received air frames and Internet Protocol (IP) packets to each other, as a router between the wireless terminal device and the rest of the access network, which can include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the properties of the air interface. For example, the network device related to the embodiments of the present application can be a network device (base transceiver station, BTS) in the global system for mobile communications (GSM) or code division multiple access (CDMA), and can also be a network device (NodeB) in wide-band code division multiple access (WCDMA), and can also be an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station in a next generation system (5G network architecture), a home evolved node B (HeNB), a relay node, a femto, a pico, etc., which are not limited in the embodiments of the present application.

[0117] The various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the order of display of the embodiments of the present application only represents the order of the embodiments, and does not represent the advantages and disadvantages of the technical solutions provided by the embodiments.

[0118] In the Active Time, the base station configures various reference signals (RS) for the UE, which can 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 above RS for the UE in the Idle or Inactive mode, and the UE cannot use the above RS to improve system performance and reduce power consumption. The 3GPP meeting currently decides to provide CSI-RS and / or TRS (TRS is a kind of CSI-RS) for the UE in the Idle or Inactive mode for time and frequency channel tracking, and the TRS and / or CSI-RS is configured through SIB (System Information Block) signaling. The TRS and / or CSI-RS can be shared with the connected state UE, or it can be understood that the TRS and / or CSI-RS used by the base station for connected state transmission is notified to the idle mode UE through SIB signaling.

[0119] Since the TRS and / or CSI-RS configured by the base station for the connected state may be accompanied by the completion of the connected state UE transmission, the TRS and / or CSI-RS transmission is quickly deactivated, resulting in the fact that the RS resource configured by the base station for the idle mode UE may not exist. Therefore, it is necessary to indicate whether the TRS and / or CSI-RS resource configured by the base station for the idle / inactive mode UE exists, that is, to indicate the availability of the TRS and / or CSI-RS at the TRS and / or CSI-RS occasion, so as to avoid the UE performing RS blind detection operation. At present, in the discussion of UE energy saving in Rel-17, the following problems are mainly focused on:

[0120] I. Whether the PEI is DCI-based or sequence-based;

[0121] II. Whether to support sub-grouping of terminals, if sub-grouping is supported, whether the sub-grouping is carried by PEI or by paging DCI that schedules the paging message;

[0122] III. There are two assumptions for the meaning of PEI and the UE's interpretation of the case where PEI is not detected:

[0123] Behavior a: If the sub-group (or directly, the group) that the UE belongs to is paged, the PEI indicates the UE to monitor the PO; if the UE does not detect the PEI in all PEI occasions corresponding to the PO, the UE does not monitor the PO.

[0124] Behavior b: The PEI indicates whether the UE should monitor the PO; if the UE does not detect the PEI in all PEI occasions corresponding to the PO, the UE needs to detect the PO.

[0125] Four, whether the RRC idle / inactive UE can obtain the TRS and / or CSI-RS is indicated by the PEI or the paging DCI.

[0126] The embodiments of the present application are mainly directed to the above problems, and propose a sequence-based PEI indication terminal sub-group paging technical scheme under the assumption of Behavior b, and can indicate the obtainability of the preset reference signal (such as including TRS and / or CSI-RS) of the UE in the RRC idle or inactive mode.

[0127] On the network side, the information transmission method proposed in the embodiments of the present application includes:

[0128] Determine the current information indicated to the terminal, and send a preset sequence set on a preset resource, used to indicate the information;

[0129] Among them, the sequence set includes one or more preset sequences, and the information includes paging information of a terminal sub-group and / or indication information of whether a terminal can obtain TRS and / or CSI-RS.

[0130] That is, in the embodiments of the present application, it is agreed in advance or the network side informs the terminal that different sequences, different sequences used to indicate information, the group to which the terminal belongs, and the correspondence between the group and the sequence of the terminal, and the like, so that only the sequence is transmitted in the information transmission process, the paging information of the terminal sub-group and / or the indication of whether the terminal can obtain TRS and / or CSI-RS can be realized. Thus, the network side overhead can be further saved, while avoiding the power consumption increase caused by unnecessary PO monitoring of the terminal, and resources are saved.

[0131] The following introduces the technical solutions provided by the embodiments of the present application from two aspects, i.e., paging information indicating only terminal grouping and indication information further indicating whether a terminal can obtain TRS and / or CSI-RS. Of course, indication information indicating only whether a terminal can obtain TRS and / or CSI-RS is the same, and thus is not described herein.

[0132] The first aspect: the method for indicating paging information of terminal grouping based on sequence signals provided by the embodiments of the present application, for example, includes the following steps.

[0133] The base station sends a preset sequence set on a preset resource, to indicate information currently needed to be indicated to a terminal.

[0134] The sequence set includes one or more preset sequences, and the information includes paging information of terminal grouping, i.e., whether a terminal in a sub-group is paged. If the terminal is paged, the terminal in the sub-group listens to paging; if the terminal is not paged, the terminal in the sub-group does not listen to paging.

[0135] Correspondingly, the terminal receives the sequence set on the preset resource.

[0136] According to the received sequence set, the terminal determines the information indicated by the network side. If the sub-group to which the terminal belongs is paged, the terminal listens to paging; if the sub-group is not paged, the terminal does not listen to paging.

[0137] The sequence set includes one or more preset sequences.

[0138] The first sequence can be sent multiple times, different first sequences correspond to different sub-groups, and are used to indicate paging information of the corresponding sub-group (i.e., paged or not paged).

[0139] The second and third sequences are used to indicate paging information of all sub-groups. The second and third sequences are sent at most once. For example, when all terminals in a cell are not paged, the sequence set includes a preset second sequence, which is used to indicate that all terminal groupings do not listen to paging. When all terminals in the cell are paged, the sequence set includes a preset third sequence, which is used to indicate that all terminal groupings listen to paging.

[0140] The first, second and third sequences are different sequences.

[0141] That is, one first sequence indicates that a UE in a corresponding sub-group listens to paging, the second sequence indicates that UEs in all sub-groups do not listen to paging, and the third sequence indicates that UEs in all sub-groups listen to paging.

[0142] Specific base station and terminal behaviors:

[0143] Base station behavior:

[0144] The base station determines the information currently indicated to the terminal, thereby determining a sequence set. The sequence set includes three types of sequences, i.e., a first sequence, a second sequence, and a third sequence. The specific sequences included in the sequence set depend on the information to be indicated.

[0145] Regarding the first sequence, if transmission is required, the base station can 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.

[0146] In an embodiment of the present application, all UEs in a cell are divided into N sub-groups, and the base station determines a one-to-one correspondence between N first sequences and N sub-groups. The N first sequences are respectively used to indicate paging information for the corresponding N sub-groups, for example, Seq_1 is used to indicate that sub-group_1 has paging, Seq_2 is used to indicate that sub-group_2 has paging, and so on, and Seq_N is used to indicate that sub-group_N has paging. Seq_1 to Seq_N are all first sequences.

[0147] In an embodiment of the present application, the base station can notify sub-group information, sequence information, correspondence between terminal grouping and sequences, and the like through configuration signaling (such as high-layer signaling). The sequence information, for example, includes the identity of the sequence and the information indicated by the sequence. Through the notification, the terminal can know the sub-group to which it belongs, the information indicated by the sequence transmitted by the network side, the correspondence between the sub-group and the first sequence, and the like.

[0148] Alternatively, an embodiment of the present application can also implement a preset rule by agreement between the network side and the terminal side. The preset rule can be used to determine terminal grouping information, sequence information, and correspondence between terminal grouping and sequences.

[0149] The sub-group information, such as a sub-group ID, indicates which sub-group the UE belongs to.

[0150] The preset rule can be used to calculate the sub-group to which the UE belongs and the corresponding first sequence, and can also be used to calculate the second sequence and the third sequence.

[0151] For example, a sub-group ID to which the terminal belongs is obtained by a formula sub-group_ID = UE_ID mod N, the sub-group ID is taken as an initial ID of the first sequence, and initial IDs of the second sequence and the third sequence are agreed in advance.

[0152] In the embodiments of the present application, the method for the base station to determine the preset resource is prior art, and the related description is made in subsequent embodiments. For the base station side and the terminal side, the preset resource is the same, the base station transmits on the resource, and the terminal receives on the resource, so the base station and the terminal both need to determine the preset resource.

[0153] After the preset resource is determined, the base station transmits a sequence on the preset resource to indicate whether the UE belonging to each sub-group listens to paging according to the paging information of all UEs in the cell. For example:

[0154] The UEs in the cell are divided into N sub-groups, and when the UEs belonging to the N sub-groups in the cell are not all paged, the base station transmits the second sequence on the preset resource;

[0155] When the paged UEs in the cell all belong to the sub-group_x, the base station transmits the first sequence (such as Seq_x) corresponding to the sub-group_x and the second sequence on the preset resource;

[0156] When the paged UEs in the cell belong to m sub-groups (m>=2), the base station transmits the third sequence on the preset resource. That is, when the paged terminals in the cell belong to different terminal groups, that is, the paged terminals are not all in one sub-group, the third sequence is transmitted to indicate that all the terminals listen to paging, although this will cause some false alarms, but can reduce the base station overhead, and the false alarm influence is not large.

[0157] Terminal behavior:

[0158] The terminal determines the sub-group to which it belongs and the corresponding first sequence, and determines the second sequence and the third sequence according to the signaling or by a preset rule.

[0159] The terminal determines the preset resource, receives the sequence on the preset resource, and performs sequence detection, for example:

[0160] When the terminal detects the first sequence corresponding to the sub-group to which it belongs and does not detect the second sequence at the same time, the terminal listens to paging; that is, when the first sequence and the second sequence are received at the same time, the second sequence is ignored and only the first sequence is considered.

[0161] 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;

[0162] When the terminal detects the second sequence and the first sequence corresponding to the sub-group to which the terminal belongs, the terminal listens to paging.

[0163] When the terminal detects the third sequence, the terminal listens to paging.

[0164] The second aspect: the base station sends one or more sequences in the sequence set on the preset resource, indicating the sub-group paging information and the obtainability (i.e. obtainable or unobtainable) of CSI-RS (e.g. including TRS).

[0165] Correspondingly, the terminal receives one or more sequences in the sequence set on the preset resource, thereby determining the paging information of itself and the obtainability of TRS and / or CSI-RS.

[0166] In the sequence set, for example, five sequences including the first sequence, the second sequence, the third sequence, the fourth sequence and the fifth sequence, what sequence is included in the specific sequence set to be sent is determined according to actual conditions;

[0167] The first sequence can be sent multiple times, and different first sequences correspond to different sub-groups, and are used to indicate the paging information of the corresponding sub-group.

[0168] The second sequence, the third sequence, the fourth sequence and the fifth sequence can all be used to indicate the paging information of all sub-groups and the obtainability of TRS (TRS is taken as an example, of course all CSI-RS are applicable), and the second, third, fourth and fifth sequences are at most one, that is, each sequence of the four sequences will not be sent multiple times at a time, because unlike the first sequence, there is no case that different terminal groups correspond to different second sequences, third sequences, fourth sequences or fifth sequences.

[0169] Indication method 1: the second and third sequences are respectively used to indicate that the sub-group has no paging and has paging, and the fourth and fifth sequences are respectively used to indicate whether the current TRS of the UE is obtainable.

[0170] That is:

[0171] Case one: when all terminals in the cell are not paged, the sequence set includes a preset second sequence, which is used to indicate that all terminal groups do not listen to paging.

[0172] Case two: when all terminals in the cell are paged, the sequence set includes a preset third sequence, which is used to indicate that all terminal groups listen to paging.

[0173] Case three: when all terminal groups can obtain TRS, the sequence set includes a preset fourth sequence, which is used to indicate that all terminal groups can obtain TRS.

[0174] Case four: when all terminal groups cannot obtain TRS, the sequence set includes a preset fifth sequence, which is used to indicate that all terminal groups cannot obtain TRS.

[0175] The above case one, case two, case three and case four can be combined two by two respectively, and two sequences are sent in the preset resource at the same time. For example, the third sequence and the fourth sequence are sent in the preset resource at the same time, or the third sequence and the fifth sequence are sent in the preset resource at the same time, and so on.

[0176] Indication method 2: the second, third, fourth and fifth sequences are respectively used to indicate that all sub-groups have paging and TRS can be obtained, all sub-groups have paging and TRS cannot be obtained, all sub-groups have no paging and TRS can be obtained, and all sub-groups have no paging and TRS cannot be obtained.

[0177] That is to say:

[0178] If all terminal groups do not listen to paging, and all terminal groups cannot obtain TRS, the sequence set includes a preset second sequence, which is used to indicate that all terminal groups do not listen to paging, and all terminal groups cannot obtain TRS.

[0179] If all terminal groups listen to paging, and all terminal groups can obtain TRS, the sequence set includes a preset third sequence, which is used to indicate that all terminal groups listen to paging, and all terminal groups can obtain TRS.

[0180] If all terminal groups do not listen to paging, and all terminal groups can obtain TRS, the sequence set includes a preset fourth sequence, which is used to indicate that all terminal groups do not listen to paging, and all terminal groups can obtain TRS.

[0181] If all terminal groups listen to paging, and all terminal groups cannot obtain TRS, the sequence set includes a preset fifth sequence, which is used to indicate that all terminal groups listen to paging, and all terminal groups cannot obtain TRS.

[0182] Specific base station and terminal behaviors:

[0183] Base station behavior:

[0184] The base station determines the information currently indicated to the terminal, thereby determining a sequence set. The sequence set includes five sequences, i.e., a first sequence, a second sequence, a third sequence, a fourth sequence, and a fifth sequence. The specific sequence set includes what sequence depends on the information to be indicated.

[0185] As to the first sequence, if transmission is needed, the base station can 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.

[0186] In the embodiments of the present application, all UEs in a cell are divided into N sub-groups, the base station determines a one-to-one correspondence between N first sequences and N sub-groups, and the N first sequences are respectively used to indicate paging information of the corresponding N sub-groups, for example, Seq_1 is used to indicate that there is paging in sub-group_1, Seq_2 is used to indicate that there is paging in sub-group_2, and so on, and Seq_N is used to indicate that there is paging in sub-group_N. Seq_1 to Seq_N are all first sequences.

[0187] In the embodiments of the present application, the base station can notify the sub-group information, the sequence information, the correspondence between the terminal grouping and the sequence, and the like through configuration signaling (such as high-layer signaling). The sequence information includes, for example, the identification of the sequence and the information indicated by the sequence. Through the notification, the terminal can know the sub-group to which it belongs, the information indicated by the sequence transmitted by the network side, the correspondence between the sub-group and the first sequence, and the like.

[0188] Alternatively, the embodiments of the present application can also implement a preset rule by agreement at the network side and the terminal side. The preset rule can be used to determine the terminal grouping information, the sequence information, and the correspondence between the terminal grouping and the sequence.

[0189] The sub-group information, such as sub-group ID, indicates to which sub-group the UE belongs.

[0190] The preset rule can be used to calculate the sub-group to which the UE belongs and the corresponding first sequence, and can also be used to calculate the second sequence, the third sequence, the fourth sequence, and the fifth sequence.

[0191] For example, the sub-group ID to which the terminal belongs can be obtained through the formula sub-group_ID = UE_ID mod N, the sub-group_ID can be used as the initial ID of the first sequence, and the initial IDs of the second, third, fourth, and fifth sequences can be agreed upon in advance.

[0192] In the embodiments of the present application, the method for determining the preset resource by the base station is described in the embodiments. The preset resource is the same for the base station side and the terminal side. The base station transmits on the resource, and the terminal receives on the resource. Therefore, the base station and the terminal both need to determine the preset resource.

[0193] After the preset resource is determined, the base station transmits a sequence on the preset resource to indicate whether the UE belonging to each sub-group listens to the paging according to the paging information of all UEs at present. For example:

[0194] For the indication method 1, one or more sequences can be transmitted on the preset resource.

[0195] When the UE to be paged in the cell all belong to sub-group_x, the base station transmits the first sequence corresponding to sub-group_x and the second sequence on the preset resource.

[0196] When the UE to be paged in the cell belong to m sub-groups (m>=2), the base station transmits the third sequence on the preset resource.

[0197] At this time, according to whether the TRS can be obtained, 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.

[0198] When the UE belonging to the N sub-groups in the cell are not paged, the base station transmits the second sequence on the preset resource. At this time, since the UE does not listen to the paging, the TRS is not needed for time-frequency synchronization. The base station can also transmit the fourth or fifth sequence on the preset resource to indicate whether the UE TRS can be obtained while transmitting the second sequence, or the base station can not transmit.

[0199] For the indication method 2, one or more sequences can be transmitted on the preset resource.

[0200] When the UE to be paged in the cell all belong to sub-group_x, if the current TRS can be obtained, the base station transmits the first sequence corresponding to sub-group_x on the preset resource, and simultaneously transmits the fourth sequence; if the current TRS cannot be obtained, the base station transmits the first sequence (such as Seq_x) corresponding to sub-group_x on the preset resource, and simultaneously transmits the fifth sequence.

[0201] When the UE belonging to the N sub-groups in the cell are not paged, if the TRS can be obtained, the base station transmits the fourth sequence on the preset resource; if the TRS cannot be obtained, the base station transmits the fifth sequence on the preset resource.

[0202] When the UE being paged in the cell belongs to m sub-groups (m >= 2), if TRS can be obtained, the base station sends the second sequence on the preset resource; if TRS cannot be obtained, the base station sends the third sequence on the preset resource.

[0203] Terminal behavior:

[0204] The terminal calculates and determines the sub-group to which it belongs and the corresponding first sequence according to signaling or through a preset rule, and determines the second sequence, the third sequence, the fourth sequence and the fifth sequence.

[0205] The terminal determines the preset resource, receives the sequence on the preset resource, and performs sequence detection, for example:

[0206] For indication method 1:

[0207] When the terminal detects the first sequence corresponding to the sub-group to which it belongs and does not detect the second sequence, the terminal listens to paging;

[0208] When the terminal detects the second sequence and does not detect the first sequence corresponding to the sub-group to which it belongs, the terminal sleeps;

[0209] When the terminal detects the second sequence and the first sequence corresponding to the sub-group to which it belongs, the terminal listens to paging;

[0210] When the terminal detects the third sequence, the terminal listens to paging.

[0211] When the terminal detects the fourth sequence, it indicates that the terminal can obtain the TRS sent by the base station;

[0212] When the terminal detects the fifth sequence or does not detect the fourth sequence, it indicates that the terminal cannot obtain the TRS sent by the base station.

[0213] For indication method 2:

[0214] If the terminal detects the first sequence corresponding to the sub-group to which it belongs and detects the fourth sequence, the terminal listens to paging and can obtain the TRS sent by the base station;

[0215] If the terminal detects the first sequence corresponding to the sub-group to which it belongs and detects the fifth sequence, the terminal listens to paging and cannot obtain the TRS sent by the base station;

[0216] If the terminal does not detect the first sequence but detects the fourth sequence, the terminal does not listen to paging but can obtain the TRS sent by the base station;

[0217] If the terminal does not detect the first sequence and detects the fifth sequence, the terminal does not listen to paging and cannot obtain the TRS sent by the base station;

[0218] If the terminal detects the second sequence, the terminal listens to paging and can obtain the TRS sent by the base station;

[0219] If the terminal detects the third sequence, the terminal listens to paging but cannot obtain the TRS sent by the base station.

[0220] The following gives an example of several specific embodiments:

[0221] Embodiment 1: The base station / terminal sends / receives one or more sequences in the sequence set on the preset resource to indicate the sub-group paging information.

[0222] Step 1: The base station determines the sub-group of the terminal and the sequence set, which includes the first sequence, the second sequence and the third sequence; the first sequence corresponds to the sub-group.

[0223] Step 2: The base station determines the preset resource. For the PEI, the preset resource is the PEI resource location. The PEI resource location and the PO resource location can be bound, for example, the PEI resource location is at a certain 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; or the PEI resource location and the SSB location can be bound, for example, the PEI resource location is at a certain number of 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.

[0224] Step 3: The base station determines which sequence to send according to the paging information of the sub-group and sends it on the preset resource to indicate whether the UE listens to paging in the corresponding PO, and which sequence to send under which paging information is as follows:

[0225] When the UEs belonging to the N sub-groups in the cell are not paged, the base station sends the second sequence;

[0226] When the paged UEs in the cell all belong to the same sub-group (sub-group_x), the base station sends the first sequence (such as Seq_x) corresponding to the sub-group_x and the second sequence;

[0227] When the paged UEs in the cell belong to m sub-groups (m>=2), the base station sends the third sequence.

[0228] Step 4: The terminal determines the preset resource. For the PEI, the preset resource is the PEI resource location. If the PEI resource location is bound to the PO resource location, the terminal calculates the PO resource location according to the formula, and determines the PEI resource location according to the correspondence between the PO and the PEI resource location; if the PEI resource location is bound to the SSB, the terminal determines the PEI resource location according to the resource location of the received SSB; or other PEI resource location determination methods. The terminal performs sequence reception detection on the PEI resource location, specifically:

[0229] When the terminal detects the first sequence corresponding to the sub-group to which it belongs, it no longer detects other sequences, and the terminal listens to the paging in the corresponding PO;

[0230] When the terminal detects the second sequence, if it does not detect the first sequence corresponding to the sub-group to which the terminal belongs, the terminal sleeps;

[0231] When the terminal detects the third sequence, it no longer detects other sequences, and the terminal listens to the paging in the corresponding PO.

[0232] For the PEI, the UE complies with Behavior b, that is, the UE does not detect the PEI and performs listening on the corresponding PO, then the base station needs to send the PEI on the PEI resource location to indicate whether the UE listens to the PO (this is equivalent to the PEI being an always-on signal). If N sequences are directly sent to indicate the paging information of N sub-groups, it will bring a considerable overhead to the base station. At present, there is no good solution to this problem of Behavior b in the existing technology. By applying the scheme proposed in the embodiment of the application, the paging information of all sub-groups can be indicated by one or a combination of two of the three sequences with different indication functions, i.e. the first, second and third sequences. The advantages of the application are analyzed in detail as follows:

[0233] The base station has small overhead. According to the step description of the application, the base station needs to send at most two sequences (the first sequence and the second sequence) on the PEI sending resource by using the method proposed in the embodiment of the application. According to the 3GPP Rel-17 energy saving discussion, the probability of being paged by the PO is about 10%, which means that the base station only needs to send one sequence on the PEI sending resource in about 90% of the time, which can greatly reduce the overhead of the base station and save the operating power of the base station.

[0234] The false alarm rate of the terminal monitoring paging is small. According to mathematical formula derivation, when the PO paging rate is 10%, the probability of multiple (more than one) sub-groups being awakened at the same time is 10%-CN1*Y*(1-Y)^(N-1), wherein Y is the probability of a sub-group being awakened (which can be calculated by the formula: 1-(1-Y)^N=10%), and N is the number of sub-groups. Through mathematical probability analysis, it can be known that, compared with only one sub-group being awakened, the probability of multiple sub-groups being awakened at the same time is very small, and the probability further decreases as the number of awakened sub-groups increases. Therefore, the method of using the third sequence to indicate that the UE of all sub-groups monitors the PO has little effect on the false alarm rate of the UE monitoring paging.

[0235] The terminal PEI detection performance is good. According to the foregoing step description of the application, there are at most two sequences on the PEI sending resource position by using the method proposed in the application. Compared with N (N>2) sequences on the PEI sending resource position, the sequence detection performance of the terminal is more beneficial by using the application, and the PEI miss detection rate is reduced. In addition, from the perspective of reducing unnecessary PO monitoring caused by terminal miss detection of PEI, the application is also more beneficial to terminal energy saving.

[0236] Embodiment 2: The base station / terminal sends / receives one or more sequences in the sequence set on the preset resource to indicate the sub-group paging information and TRS and / or CSI-RS obtainability--indication method 1.

[0237] Step 1: The base station determines the sub-group of the terminal and a sequence set, wherein the sequence set includes a first sequence, a second sequence and a third sequence; and the first sequence corresponds to the sub-group.

[0238] Step 2: The base station determines a preset resource. For the PEI, the preset resource is the PEI resource position. The PEI resource position and the PO resource position can be bound, for example, the PEI resource position is at a plurality of time slots before the PO, and the base station further determines the PEI resource position by determining the PO resource position; or the PEI resource position and the SSB resource position can be bound, for example, the PEI resource position is at a plurality of time slots after the SSB resource position, and the base station further determines the PEI resource position by determining the SSB resource position; or other PEI resource position determination methods.

[0239] Step 3: The base station determines which sequence(s) to send and on which pre-set resource to send according to the paging information of the sub-group and the TRS and / or CSI-RS obtainability to indicate whether the UE listens to the paging in the corresponding PO and whether the TRS and / or CSI-RS is obtainable, and in which case which sequence(s) is / are sent as follows:

[0240] When the paged UEs in the cell all belong to sub-group_x, and the TRS and / or CSI-RS is obtainable, the base station sends the first sequence, the second sequence and the fourth sequence corresponding to sub-group_x on the pre-set resource; when the paged UEs in the cell all belong to sub-group_x, and the TRS and / or CSI-RS is unobtainable, the base station sends the first sequence, the second sequence and the fifth sequence corresponding to sub-group_x on the pre-set resource;

[0241] When the paged UEs in the cell belong to m sub-groups (m>=2), and the TRS and / or CSI-RS is obtainable, the base station sends the third sequence and the fourth sequence on the pre-set resource; when the paged UEs in the cell belong to m sub-groups (m>=2), and the TRS and / or CSI-RS is unobtainable, the base station sends the third sequence and the fifth sequence on the pre-set resource.

[0242] When the UEs belonging to the N sub-groups in the cell are all not paged, the base station sends the second sequence on the pre-set resource. At this time, since the UE does not listen to the paging, it does not need to use the TRS for time-frequency synchronization, and the base station can send the fourth / fifth sequence on the pre-set resource to indicate whether the UE TRS is obtainable, or not send.

[0243] Step 4: The terminal determines the pre-set resource. For the PEI, the pre-set resource is the PEI resource location. If the PEI resource location is bound to the PO, the terminal calculates the location of the PO according to the formula, and determines the PEI resource location according to the correspondence between the PO and the PEI resource location; if the PEI resource location is bound to the SSB, the terminal determines the PEI resource location according to the resource location of the received SSB; or other PEI resource location determination method. The terminal performs sequence reception detection on the PEI resource location, specifically:

[0244] When the terminal detects the first sequence corresponding to the sub-group to which it belongs, the terminal listens to the paging in the corresponding PO;

[0245] When the terminal detects the second sequence, if it does not detect the first sequence corresponding to the sub-group to which the terminal belongs, the terminal sleeps;

[0246] When the terminal detects the third sequence, the terminal listens to the paging in the corresponding PO;

[0247] When the terminal detects the fourth sequence, the terminal can obtain the TRS and / or CSI-RS transmitted by the base station;

[0248] When the terminal detects the fifth sequence, the terminal cannot obtain the TRS and / or CSI-RS transmitted by the base station.

[0249] By applying the scheme proposed in the embodiment of the present application, all sub-group paging information and TRS obtainability can be indicated by the combination of one or more sequences in the five sequences with different functions, i.e., the first, second, third, fourth, and fifth sequences. The advantages of Embodiment 1 are also applicable to the present embodiment. Compared with Embodiment 1, two sequences are added in the sequence set in the present embodiment, which can indicate the TRS and / or CSI-RS obtainability of the terminal, and the base station transmits at most three sequences in the preset resource.

[0250] Embodiment 3: Base station / terminal transmits / receives one or more sequences in the sequence set on the preset resource to indicate the sub-group paging information and TRS and / or CSI-RS obtainability—indication method 2.

[0251] Step 1: The base station determines the sub-group of the terminal and the sequence set, wherein the sequence set includes a first sequence, a second sequence, and a third sequence; and the first sequence corresponds to the sub-group.

[0252] Step 2: The base station determines the preset resource. For the PEI, the preset resource is the PEI resource location. The PEI resource location and the PO resource location can be bound, for example, the PEI resource location is at a certain 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; or the PEI resource location and the SSB location can be bound, for example, the PEI resource location is at a certain number of 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.

[0253] Step 3: The base station determines which sequence to transmit according to the paging information of the sub-group and the TRS and / or CSI-RS obtainability and transmits it on the preset resource to indicate whether the UE listens to the paging in the corresponding PO and whether the TRS and / or CSI-RS can be obtained, and the specific conditions under which which sequence is transmitted are as follows:

[0254] When the UE being paged in the cell all belong to sub-group_x, and TRS and / or CSI-RS can be obtained, the base station transmits the first sequence and the fourth sequence corresponding to sub-group_x on the preset resource; when the UE being paged in the cell all belong to sub-group_x, and TRS and / or CSI-RS cannot be obtained, the base station transmits the first sequence and the fifth sequence corresponding to sub-group_x on the preset resource.

[0255] When the UE being paged in the cell belong to m sub-groups (m>=2), and TRS can be obtained, the base station transmits the second sequence on the preset resource; when the UE being paged in the cell belong to m sub-groups (m>=2), and TRS and / or CSI-RS cannot be obtained, the base station transmits the third sequence on the preset resource.

[0256] When the UE belonging to the N sub-groups in the cell are not paged, and TRS and / or CSI-RS can be obtained, the base station transmits the fourth sequence on the preset resource; when the UE belonging to the N sub-groups in the cell are not paged, and TRS and / or CSI-RS cannot be obtained, the base station transmits the fifth sequence on the preset resource.

[0257] Step 4: The terminal determines the preset resource. For PEI, if the PEI resource position is bound to PO, the terminal determines the position of PO according to the formula, and determines the PEI resource position according to the correspondence between PO and the PEI resource position; if the PEI resource position is bound to SSB, the terminal determines the PEI resource position according to the resource position of the received SSB; or other PEI resource position determination method. The terminal performs sequence receiving detection on the preset resource, specifically:

[0258] When the terminal detects the first sequence corresponding to the sub-group to which it belongs, the terminal listens to the paging in the corresponding PO; at the same time, if the terminal detects the fourth sequence on the preset resource, the terminal can obtain the TRS and / or CSI-RS transmitted by the base station, and if the terminal detects the fifth sequence on the preset resource, the terminal cannot obtain the TRS and / or CSI-RS transmitted by the base station.

[0259] When the terminal does not detect the first sequence corresponding to the sub-group to which it belongs, if the terminal detects the fourth sequence, the terminal sleeps and can obtain the TRS and / or CSI-RS transmitted by the base station; if the terminal detects the fifth sequence, the terminal sleeps and cannot obtain the TRS and / or CSI-RS transmitted by the base station.

[0260] If the terminal detects the second sequence, the terminal listens to the paging in the corresponding PO and can obtain the TRS transmitted by the base station.

[0261] If the terminal detects the third sequence, the terminal monitors paging corresponding to the PO and cannot obtain the TRS transmitted by the base station.

[0262] By using the scheme proposed in the embodiment of the present application, all sub-groups paging information and TRS obtainability can be indicated by the combination of one or more sequences in the five sequences with different functions, i.e., the first, second, third, fourth and fifth sequences. The advantages of the embodiment 2 are also applicable to the present embodiment. Compared with the embodiment 2, the base station using the present embodiment transmits at most two sequences on the preset resource.

[0263] In summary, the embodiment of the present application can indicate the paging information of all sub-groups in a cell by transmitting fewer sequences, and the specific advantages are as follows:

[0264] The base station overhead is small. By using the method proposed in the embodiment of the present application, the base station needs to transmit at most two / three sequences on the PEI transmission resource. According to the 3GPP Rel-17 energy saving discussion, the probability of being paged by the PO is about 10%, which means that the base station only needs to transmit one sequence on the PEI transmission resource in about 90% of the time, which can greatly reduce the base station overhead and save the base station operating power.

[0265] The influence on the terminal paging false alarm rate is small. According to mathematical formula derivation, when the PO paging rate is 10%, the probability of multiple (more than one) sub-groups being awakened at the same time is 10%-CN1*Y*(1-Y)^(N-1), where Y is the probability of a sub-group being awakened, and N is the number of sub-groups. Through mathematical probability analysis, it can be known that compared with only one sub-group being awakened, the probability of multiple sub-groups being awakened at the same time is very small, and the probability further decreases as the number of awakened sub-groups increases. Therefore, the method of using one sequence to indicate the UE of all sub-groups to monitor the PO has less influence on the UE paging false alarm rate.

[0266] The terminal PEI detection performance is good. According to the foregoing description of the steps of the present application, by using the method proposed in the embodiment of the present application, at most two sequence signals exist on the PEI resource location. Compared with detecting N (N is the number of sub-groups) sequences, the sequence detection performance of the terminal is more favorable by using the embodiment of the present application, and the PEI miss detection rate is reduced. In addition, from the perspective of reducing unnecessary PO monitoring caused by terminal miss detection of PEI, the embodiment of the present application is also more beneficial to terminal energy saving.

[0267] The embodiment of the present application can also indicate the paging information and TRS and / or CSI-RS obtainability of all sub-groups in a cell by transmitting fewer sequences.

[0268] Referring to Figure 1 At the network side, an information transmission method provided by the embodiment of the application includes:

[0269] S101, determining information currently indicated to a terminal;

[0270] S102, sending a preset sequence set on a preset resource, for indicating the information;

[0271] The sequence set includes one or more preset sequences, and the information includes paging information of a terminal group and / or indication information of whether the terminal can obtain a preset reference signal.
