In order to save energy consumption of terminal devices in an idle state, a network side configures reference signal transmission resources for the terminal devices through system broadcast information in a current manner, that is, the terminal devices in the idle state and the terminal devices in a connected state may share the reference signal resources. The terminal equipment has two modes to determine the availability of the reference signal transmission resource in an idle state:

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.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

First, a description will be given of background art and terminology in the embodiments of the present application.

CSI-RS: channel-State Information Reference Signal (Channel-State Information Reference Signal);

TRS: a multi-periodic CSI-RS can be understood as a phase reference signal (tracking reference signal).

Packing message: the paging message has the functions of: (1) Sending a call request to the terminal equipment in the RRC _ IDLE state; (2) Informing the terminal equipment in the RRC _ IDLE/INACTIVE and RRC _ CONNECTED states that the system information is changed; (3) The earthquake and tsunami notification indicates that the terminal equipment starts to receive the ETWS primary notification and/or the ETWS secondary notification; instructing the terminal device to start receiving the CMAS notification. If the terminal equipment is paged or the system information is updated or an earthquake and tsunami occur, the base station firstly sends a wake-up signal, the terminal equipment monitors a paging PDCCH (physical downlink control channel) and receives a paging message after detecting the wake-up signal, otherwise, the terminal equipment keeps a sleep state all the time to achieve the purpose of saving electricity. In NR, the UE may use Discontinuous Reception (DRX) in RRC _ IDLE and RRC _ INACTIVE states in order to reduce power consumption. The UE periodically (the Paging cycle is a DRX cycle) monitors the Paging Occasion (PO).

In addition, before the UE receives Paging, the UE needs to use a reference signal (e.g., SSB) to complete time-frequency synchronization and AGC (automatic gain control) adjustment.

PEI: paging Early Indication (Paging Early Indication), in order to save power consumption of the terminal device, in a DRX scenario, each PO may be associated with one PEI, and the terminal device may receive the PEI before monitoring the POs to determine whether monitoring of the POs associated with the PEI is needed, so as to achieve a purpose of saving power consumption;

in an eDRX (Extended idle mode DRX) scenario, in each eDRX cycle, there is a Paging Time Window PTW (Paging Time Window), and the terminal device monitors a Paging channel in the PTW according to the DRX cycle (the DRX cycle Time is short, and it can be considered that the terminal device is not dormant and can be reached all the Time) so as to receive downlink data, and the terminal device is in a dormant state at the rest of Time. That is, in an eDRX (Extended idle mode DRX) scenario, one PEI may associate multiple POs (assuming m POs), that is, the terminal device receives a PEI indication, and may determine whether the subsequent m POs need to monitor.

According to the paging rate (10%) of the terminal device group in the existing network, generally, more than 90% of probability PEI indicates that the terminal device does not wake up to monitor PDCCH in its corresponding PO.

The following is to describe the activity of the terminal device in idle/inactive state, when in idle/inactive state, for the measurement of the serving cell, the terminal device basically performs the measurement activity of the serving cell in each DRX cycle, and the purpose of the measurement activity is to perform cell reselection when one is used, and to complete time-frequency synchronization and Automatic Gain Control (AGC) adjustment before monitoring the PO.

In idle/inactive state, before the terminal device receives Paging in each DRX cycle, the terminal device needs to utilize multiple (e.g., 3) synchronization signal blocks (SS/PBCH block, SSB) to complete time-frequency synchronization, AGC adjustment, and Radio Resource Management (RRM) measurement for a serving cell. Since SSBs are periodically transmitted (the period size is at the cell level, that is, the SSB transmission period of a cell is the same), it cannot be guaranteed that each PO (the period of the PO is at the terminal device level, and each terminal device has its specific PO period) is close to a certain SSB, if the distance between the SSB and the PO is large, the terminal device needs to wake up many times to receive paging (it is assumed that 2 SSBs are needed to complete time frequency synchronization, AGC adjustment and RRM measurement for the serving cell, wake up 3 times is needed, 2 times are needed to perform time frequency synchronization/AGC adjustment/RRM measurement for the serving cell, and 1 time is needed to monitor the PO), and if the SSB is close to the PO, the terminal device only needs to wake up 2 times to complete time frequency synchronization, AGC adjustment, measurement for the serving cell, and paging reception.

Further, in idle/inactive state, frequent waking up of the terminal device to perform related activities (i.e. frequency synchronization, AGC adjustment and serving cell measurement) may increase the power consumption of the terminal device. At present, the 3GPP adopts a solution that a network side configures a periodic TRS/CSI-RS transmission resource for a terminal device in idle/inactive state through system broadcast information, that is, the terminal device in idle/inactive state and a terminal device in connected state can share the TRS/CSI-RS. The terminal equipment in idle/inactive state can utilize the TRS/CSI-RS to complete activities such as AGC adjustment/time frequency synchronization and the like so as to reduce the waking times of the terminal equipment, namely, the terminal equipment can centralize time frequency synchronization, AGC adjustment and measurement of a service cell through the TRS/CSI-RS so as to reduce the waking times of UE.

For example, as shown in fig. 1, when there is an additional reference signal (ARS, or TRS/CSI-RS) in front of (and close to) the PO, the UE only needs to wake up 2 times to complete time-frequency synchronization, measurement and Paging reception. However, in idle/inactive state, the availability of the TRS/CSI-RS resource needs to indicate the terminal device by the network side, that is, the terminal device needs to determine whether the resource of the subsequent TRS/CSI-RS is valid (i.e., determine whether the base station sends the TRS/CSI-RS at the transmission time of the subsequent TRS/CSI-RS) by receiving the TRS/CSI-RS validity indication message sent by the network side in advance.

In order to more flexibly indicate the effectiveness of the TRS/CSI-RS, and reduce the bit overhead and the power consumption of the terminal device, and the like, embodiments of the present application provide a message transmission method and a related apparatus, which can dynamically and flexibly indicate the availability of the reference signal resource by a Paging DCI and PEI joint indication manner, and reduce the power consumption and the bit overhead of the terminal device.

In this embodiment, the terminal device is a UE side, and the access network device is a network side, which are not described herein again.

A message transmission method in the embodiment of the present application is described below with reference to fig. 3, and fig. 3 is a schematic flowchart of a message transmission method provided in the embodiment of the present application, which is applied to a terminal device, and specifically includes the following steps:

step 301, obtaining configuration information.

The configuration information includes duration information and transmission resource configuration information, the duration information is used for indicating the effective duration of the first message, and the transmission resource configuration information includes configuration information of at least one transmission resource subset and configuration information of at least one transmission resource included in each transmission resource subset;

the configuration information may be obtained by receiving system information or an RRC signaling from a network side, where each transmission resource subset includes at least one transmission resource, it may be understood that the transmission resource in this embodiment of the application is a TRS/CRI-RS resource or a TRS/CRI-RS resource set, the duration information may include a first duration T1 or a second duration T2, T1 is an integer multiple of a paging cycle, a unit of T2 may be a paging cycle, a millisecond, a timeslot, a subframe, a frame, and the like, and two message transmission modes exist according to different configured duration information, which is not described herein in detail, and see description of subsequent steps.

By acquiring the configuration information, two message receiving modes with the effective duration of T1 and T2 can be provided for the terminal equipment in the scene of reference signal availability indication, and the flexibility of reference signal availability indication is improved.

Step 302, receiving the first message.

For example, if the network side configures a transmission resource subsets through configuration information, where a is a natural number greater than 1, b first transmission resource subsets in the active state exist in the transmission resource subsets a, and b is a natural number less than or equal to a, the terminal device may determine the b first transmission resource subsets in the transmission resource subsets a by receiving the first message.

Specifically, the first message may include first bit field information in Paging downlink control information Paging DCI, and further, the first bit field information includes a first bit value, where the first bit value represents a value of each bit in the first bit field, each bit in the first bit field and the first transmission resource subset have a first mapping relationship, and the first mapping relationship is indicated by system information or RRC signaling; the first bit field information may also include a first bit field value, where the first bit field value represents a value of the first bit field. The terminal device may receive the Paging DCI and read the first bit value or the first bit field value, which is not specifically limited herein.

Further, how the first bit field information indicates whether the transmission resource subset is in the active state is described herein, it can be understood that the network side may determine the number of bits in the first bit field according to the number of the transmission resource subsets, that is, the number of the transmission resource subsets is equal to the number of bits in the first bit field. In a possible embodiment, a first mapping relationship may be established between each bit in the first bit field and each transmission resource subset configured on the network side, that is, each bit corresponds to one transmission resource subset, and when a bit value is 1, the terminal device may determine that the corresponding transmission resource subset is in an active state, where the transmission resource subset is the first transmission resource subset; when the bit value is 0, the terminal device may determine that the corresponding transmission resource subset is in an inactive state, and the transmission resource subset is not the first transmission resource subset. In another possible embodiment, the network side may also directly perform integral value taking on the first bit field to obtain a value of the first bit field, for example, if there are three transmission resource subsets, which are respectively C1, C2, and C3, then the value of the first bit field is 00, which indicates that all the three transmission resource subsets are in an inactive state, and there is no first transmission resource subset; when the value of the first bit field is 01, C1 is a first transmission resource subset; when the value of the first bit field is 10, C2 is a first transmission resource subset; when the value of the first bit field is 11, it means that C3 is the first subset of transmission resources. The terminal device may determine a first transmission resource subset of the at least one transmission resource subset configured on the network side by reading the first bit field value.

In a possible embodiment, when the configured duration information is T1, the terminal device may receive Paging DCI at a first Paging occasion PO1 to read the first bit value or the first bit field value, where the first Paging occasion PO1 is determined according to a Paging parameter and the first duration T1, where the Paging parameter includes a Paging Frame Number N, a starting Paging Frame Number PF _ offset, and a user identifier UE _ ID in the Paging cycle in an existing protocol, and is used to determine a Paging Frame PF and a first Paging index i _ s, where the Paging Frame represents a System Frame Number SFN (System Frame Number) corresponding to the first Paging occasion PO1, and the first Paging index i _ s represents an index of the first Paging occasion in the Paging Frame.

The specific steps for determining PO1 are as follows:

first, PF is determined according to PF _ offset, T1, N and UE _ ID, that is, SFN of PO1 is determined, and the formula is as follows:

(SFN+PF_offset)mod T1＝(T1 div N)*(UE_ID mod N)

then, a first paging occasion index PO1 dex specifically used for receiving the TRS/CSI-RS availability indication is determined in the PF according to the parameter i _ s, and the formula is as follows:

i_s＝floor(UE_ID/N)mod Ns

wherein the content of the first and second substances,

SFN: system Frame Number, system Frame Number;

PF _ offset: the starting time interval, namely the starting frame number, of the PF is determined in the existing protocol;

n: the number of PFs within a Paging cycle in an existing protocol;

UE_ID：5G-S-TMSI mod 1024；

i _ s: index in PF for determined PO1 (starting from 0);

t1: the effective duration T1 of TRS/CSI-RS availability indication;

ns: number of POs in one PF.

Further, the terminal device may receive the Paging DCI at the PO1 to read the first bit value or the first bit field value, and determine, according to the first bit value or the first bit field value, the first transmission resource subset in an activated state in all transmission resource subsets configured by the network side.

In a possible embodiment, when the configured duration information is the second duration T2, and when any paging occasion PO receives the paging DCI and reads the first bit value or the first bit field value, a Timer is triggered, a timing duration of the Timer is equal to T2, it can be understood that the paging DCI information in T2 is valid, and once the Timer expires, the terminal device needs to receive the paging DCI again to determine the first transmission resource subset in all the transmission resource subsets configured by the network side. The terminal device may receive the paging DCI, and read the first bit value or the first bit field value to determine the first transmission resource subset in an active state in all transmission resource subsets configured on the network side, which is not described herein again.

It can be seen that two valid durations are set, the first message is received through two modes, the receiving mode can be flexibly configured according to an actual scene, the flexibility of receiving the first message is improved, and the first transmission resource subset in the activated state is determined through the paging DCI, so that the efficiency of subsequently indicating the availability of the reference signal resource can be improved, the bit overhead is reduced, and the power consumption of the terminal device is reduced.

Step 303, reading the second message within the validity duration.

Wherein the second message is used to indicate an availability status of each first transmission resource in the first subset of transmission resources, it is understood that each first subset of transmission resources includes at least one first transmission resource, and the availability status may be available or unavailable, and the first transmission resource is a reference signal TRS/CRI-RS resource or a reference signal TRS/CRI-RS resource set. The second message may include second bit field information in the PEI indicated by the paging advance.

Specifically, the second bit field information includes a second bit value, where the second bit value indicates a value of each bit in a second bit field, and each bit in the second bit field has a second mapping relationship with the first transmission resource in the first transmission resource subset, where the second mapping relationship is indicated by the system information or the RRC signaling; the second bit field information may also include a second bit field value, where the second bit field value represents a value of the second bit field. The terminal device may receive the PEI and read the second bit value or the second bit field value, which is not specifically limited herein.

Further, describing how the second bit field information indicates the availability status of each first transmission resource in the first transmission resource subset, it can be understood that the network side may determine the number of bits in the second bit field according to the number of first transmission resources in each first transmission resource subset, that is, the number of first transmission resources in each first transmission resource subset is equal to the number of bits in the second bit field. In a possible embodiment, a second mapping relationship may be established between each bit in the second bit field and the first transmission resource in each first transmission resource subset, that is, each bit corresponds to one first transmission resource in the first transmission resource subset, and when the bit value is 1, the availability status of the corresponding first transmission resource is determined to be available; and when the bit value is 0, determining that the availability state of the corresponding first transmission resource is unavailable. In another possible embodiment, the network side may also directly perform integral value taking on the second bit field to obtain a value of the second bit field, for example, if a certain subset of the first transmission resources includes three first transmission resources, which are s1, s2, and s3, respectively, the value of the second bit field is 00, which indicates that none of the three first transmission resources is available; when the value of the second bit field is 01, s1 is available, and s2 and s3 are unavailable; when the value of the second bit field is 10, s2 is available, and s1 and s3 are unavailable; a second bit field value of 11 indicates that s3 is available and s1 and s2 are not. The terminal device may read the second bit value or the second bit field value within the effective duration to determine the availability status of each first transmission resource in the first transmission resource subset, which is not described herein again.

In a possible embodiment, when the duration information is T1, the PEI may be received in T1 after PO1 to read the second bit value or the second bit field value, and determine availability of each first transmission resource in the first transmission resource subset.

For example, as shown in fig. 4A, fig. 4A is a schematic diagram of a reference signal availability indication provided in the embodiment of the present application, and it can be seen that a terminal device receives and reads Paging DCI at PO1, where the Paging DCI indicates that C1 is a first subset of transmission resources, and C1 includes two first transmission resources, which are S1 and S2 respectively, the terminal device may receive PEI within an effective duration T1 and read a second bit value at this time, and when the second bit value is 11, it is determined that S1 and S2 are both available; when the value of the second bit is 01, determining that S1 is unavailable and S2 is available; and when the second bit value is 00, determining that both S1 and S2 are unavailable.

As shown in fig. 4B, fig. 4B is a schematic diagram of another reference signal availability indication provided in this embodiment of the present application, and it can be seen that a terminal device receives and reads Paging DCI at PO1, where the Paging DCI indicates that C1 and C2 are first transmission resource subsets, C1 includes two first transmission resources, respectively S1 and S2, and C2 includes two first transmission resources, respectively S3 and S4, then the terminal device may receive the Paging DCI within an effective duration T1, and read a second bit value at this time to determine availability of each first transmission resource in C1 and C2, and when the second bit is 11, determine that S1 and S2 in C1 are available, and S3 and PEI 4 in C2 are available; when the second bit value is 01, determining that S1 in C1 is unavailable, S2 is available, S3 in C2 is unavailable, and S4 is available; when the second bit value is 00, it is determined that S1 and S2 in C1 are not available and S3 and S4 in C2 are not available. I.e. each subset of first transmission resources determines the availability of each first transmission resource in each subset of first transmission resources according to the second bit field information in the PEI.

The second bit field value can be obtained by the above method, and is not described herein again.

In a possible embodiment, when the duration information is T2, the PEI may be received within a Timer timing duration T2 to read the second bit value or the second bit field value, and determine an availability of each first transmission resource in the first subset of transmission resources.

For example, as shown in fig. 4C, fig. 4C is a schematic diagram of another reference signal availability indication provided in the embodiment of the present application, and it can be seen that a terminal device triggers a Timer when any PO receives and reads Paging DCI, where the Paging DCI indicates that C1 is a first transmission resource subset, C1 includes two first transmission resources, which are S1 and S2 respectively, and then the terminal device may receive PEI during a running period of the Timer, that is, T2, and read a second bit value at this time, and when the second bit value is 11, it is determined that both S1 and S2 are available; when the value of the second bit is 01, determining that S1 is unavailable and S2 is available; and when the second bit takes the value of 00, determining that both S1 and S2 are unavailable.

As shown in fig. 4D, fig. 4D is a schematic diagram of another reference signal availability indication provided in this embodiment, and it can be seen that a terminal device triggers a Timer when any PO receives and reads Paging DCI, where the Paging DCI indicates that C1 and C2 are first transmission resource subsets, C1 includes two first transmission resources, that is, S1 and S2, and C2 includes two first transmission resources, that is, S3 and S4, respectively, then the terminal device may receive PEI during the running period of the Timer, that is, T2, and read a second bit value at this time, and when the second bit value is 11, it is determined that S1 and S2 in C1 are available, and S3 and S4 in C2 are available; when the second bit value is 01, determining that S1 in C1 is unavailable and S2 in C2 is unavailable, and S3 in C2 is unavailable and S4 in C2 is available; and when the second bit value is 00, determining that S1 and S2 in C1 are unavailable, and S3 and S4 in C2 are unavailable.

Therefore, the second message is read in the effective duration, the two reference signal availability indication strategies of the effective duration are also suitable, the availability of each transmission resource can be flexibly indicated by combining the first message and the second message, and the power consumption and the bit overhead of the terminal equipment are greatly reduced.

Next, with reference to fig. 5, another message transmission method in this embodiment is described, where fig. 5 is a schematic flowchart of another message transmission method provided in this embodiment, and is applied to an access network device, and specifically includes the following steps:

step 501, sending configuration information, a first message and a second message.

The configuration information can be determined through system information or RRC signaling, and comprises duration information and transmission resource configuration information; the duration information comprises a first duration T1 or a second duration T2, and is used for indicating the effective duration of the first message and the effective reading time of the second message; the transmission resource configuration information comprises configuration information of at least one transmission resource subset and configuration information of at least one transmission resource contained in each transmission resource subset; the first message is used for indicating a first transmission resource subset in an active state in the at least one transmission resource subset; the second message is used to indicate an availability status of each first transmission resource in the first transmission resource subset, where the first transmission resource is a reference signal resource or a reference signal resource set, and it can be understood that the transmission resource in this embodiment of the present application is a TRS/CRI-RS resource or a TRS/CRI-RS resource set.

Specifically, the first message includes first bit field information in Paging downlink control information Paging DCI, and the second message includes second bit field information in PEI indicated in advance by Paging. The first bit field information may include a first bit value or a first bit field value, and the second bit field information may include a second bit value or a second bit field value.

In a possible embodiment, the network side may determine the number of bits in the first bit field according to the number of the transmission resource subsets, and then establish a first mapping relationship between each of the transmission resource subsets and the bits in the first bit field, where the first mapping relationship is indicated by the system information or the RRC signaling. As such, the value of each bit in the first bit field may indicate whether the corresponding subset of transmission resources is in an active state. For example, the network side configures 3 reference signal resource sets, which are C1, C2, and C3 respectively, determines that the number of bits in the first bit field is 3, sets that the first bit corresponds to C1, the second bit corresponds to C2, and the third bit corresponds to C3, where a bit value of 1 indicates that the transmission resource subset corresponding to the bit is the first transmission resource subset in the active state, and a bit value of 0 indicates that the transmission resource subset corresponding to the bit is not in the active state, for example, if the first bit value is 110, it indicates that C1 and C2 are the first transmission resource subset, and C3 is not the first transmission resource subset; for example, if the first bit is 000, it means that none of C1, C2 and C3 is the first subset of transmission resources. And will not be described in detail herein.

In a possible embodiment, the network side may also directly perform integral value taking on the first bit field to obtain a value of the first bit field, for example, if there are three transmission resource subsets, which are respectively C1, C2, and C3, then the value of the first bit field is 00, which indicates that all the three transmission resource subsets are in an inactive state, and there is no first transmission resource subset; when the value of the first bit field is 01, C1 is a first transmission resource subset; when the value of the first bit field is 10, C2 is a first transmission resource subset; when the value of the first bit field is 11, it means that C3 is the first transmission resource subset.

In a possible embodiment, the network side may determine the number of bits in the second bit domain according to the number of first transmission resources in each first transmission resource subset, that is, the number of first transmission resources in each first transmission resource subset is equal to the number of bits in the second bit domain. In a possible embodiment, a second mapping relationship may be established between each bit in the second bit field and each first transmission resource, that is, each bit corresponds to one first transmission resource, and when a bit value is 1, the availability status of the corresponding first transmission resource is determined to be available; and when the bit value is 0, determining that the availability state of the corresponding first transmission resource is unavailable.

In another possible embodiment, the network side may also directly perform integral value taking on the second bit field to obtain a value of the second bit field, for example, if a certain subset of the first transmission resources includes three first transmission resources, which are s1, s2, and s3, respectively, the value of the second bit field is 00, which indicates that none of the three first transmission resources is available; when the value of the second bit field is 01, s1 is available, and s2 and s3 are not available; when the value of the second bit field is 10, s2 is available, and s1 and s3 are not available; a second bit field value of 11 indicates that s3 is available and s1 and s2 are not. The terminal device may read the second bit value or the second bit field value within the valid duration to determine the availability status of each first transmission resource in the first transmission resource subset, which is not described herein again.

Therefore, by the method, the availability of each transmission resource can be flexibly indicated by combining the first message and the second message, and the power consumption and the bit overhead of the terminal equipment are greatly reduced.

To more clearly describe the message transmission method in the embodiment of the present application, another message transmission method in the embodiment of the present application is described below with reference to fig. 6, where fig. 6 is another message transmission method provided in the embodiment of the present application, and is applied to a terminal device and an access network device, that is, a UE side and a network side, and specifically includes the following steps:

step 601, determining configuration information, a first message and a second message.

Step 602, sending the configuration information, the first message and the second message.

Step 603, obtaining configuration information.

Step 604, a first message is received.

Step 605, the second message is read within the validity duration.

The above steps that are not described in detail can be referred to the description of the steps of the foregoing method, and are not described again here.

In a possible embodiment, when the duration information is T1, the corresponding Paging DCI is not received at the first Paging occasion, or when the corresponding Paging DCI is received at the first Paging occasion PO1 but the first bit domain information indicates that the first transmission resource subset does not exist in the at least one transmission resource subset, the second bit domain information may be ignored within the first duration T1, and the availability status of the first transmission resource is unavailable.

In a possible embodiment, when the duration information is T1, and when the corresponding Paging DCI is not received at the first Paging time, a second transmission resource subset in an active state in the at least one transmission resource subset may be determined according to first bit field information in the Paging DCI received at a second Paging time, where the second Paging time PO2 is determined before the first Paging time PO1 and also according to the Paging parameter and the first duration, and in brief, PO2 is a Paging time determined in a Paging cycle before PO1, which is not described herein again;

then, PEI may be received within the first time duration T1 and the second bit value or the second bit field value may be read to determine an availability status of each transmission resource in the second subset of transmission resources, where the transmission resource is a reference signal resource or a set of reference signal resources.

In an optional embodiment, when the timer exceeds the second duration and then receives the paging DCI, or when the timer exceeds the second duration and then receives the paging DCI but the first bit field information indicates that the first transmission resource subset does not exist in the at least one transmission resource subset, ignoring the second bit field information, the availability status of the third transmission resource is unavailable.

To sum up, the message transmission method disclosed in the embodiment of the present application may combine the first message and the second message to flexibly indicate the availability of each transmission resource, thereby greatly reducing the power consumption and bit overhead of the terminal device.
