The execution bodies involved in the embodiments of the present disclosure include, but are not limited to, UEs such as mobile phone terminals that support cellular mobile communication, and base stations.

An application scenario of the embodiments of the present disclosure is that a paging early indication (PEI, paging early indication) may be used to indicate whether there is a paging message of the UE in the PO after the PEI. If there is no paging message of the UE in the PO, the UE can keep a dormant state at the PO position, thereby saving power. How to indicate the PEI to the UE is an urgent problem to be solved.

As shown in FIG. 2, this exemplary embodiment provides a PEI indication method, and the PEI indication method can be applied to a base station of a cellular mobile communication system, including:

Step 201: Use a reference signal to indicate the PEI, where the transmission resource of the reference signal is used to indicate the UE group that receives the reference signal, that is, to indicate which group of UEs receive the reference signal.

Using reference signals of different transmission resources instructs UEs in different groups to receive corresponding reference signals. For example, the reference signal using the first type of transmission resource instructs the UE in group 1 and group 2 to receive the reference signal; the reference signal using the second type of transmission resource instructs the UE in group 3 to receive the reference signal. Different transmission resources occupy different time domain and/or different frequency domain locations.

Here, the UE may be a mobile phone terminal or the like that uses a cellular mobile communication technology to perform wireless communication. The base station may be a communication device that provides an access network interface to a UE in a cellular mobile communication system. The UE may be a UE in an idle state or an inactive state.

The reference signal may be a signal for the UE to perform downlink synchronization. The signal configuration information may be used to indicate the configuration of the reference signal, such as the transmission resource configuration of the reference signal.

In one embodiment, the reference signal includes: TRS and/or CSI-RS.

Here, the TRS and/or CSI-RS may be TRS and/or CSI-RS shared by idle UEs and/or inactive UEs and/or connected UEs. The idle state UE and/or the inactive state UE may monitor the TRS and/or CSI-RS at the TRS and/or CSI-RS occasion with the connected state UE.

Exemplarily, the idle state UE and/or the inactive state UE may perform downlink synchronization based on the monitored TRS and/or CSI-RS.

The base station usually configures a set of TRS and/or CSI-RS signal configuration information for a connected UE. The base station may send the signal configuration information to the connected UE through dedicated signaling. The base station may also broadcast the signal configuration information to idle UEs and/or inactive UEs through system information or the like.

PEI may be carried by reference signals such as TRS and/or CSI-RS. The PEI can indicate two states of having a paging message and not having a paging message in the PO, and the UE can wake up or stay dormant in the PO according to the indication of the PEI. The two states of PEI can be characterized by different codes of reference signals, transmission resources, and the like.

If all UEs receive paging information at the PO based on the same PEI indication, the probability of the UE being woken up by mistake will increase, thereby increasing the power consumption of the UE.

The UE may be divided into multiple UE groups, for example, the UEs within the coverage of the base station may be divided into 4 UE groups or 16 UE groups, and so on. Different PEIs are associated with UEs grouped by 1 or more UEs. That is, one PEI may indicate that a UE of one group or a plurality of groups of UEs monitors the paging message at the PO or stays dormant at the PO. The UE may determine, based on the PEI indicated by the received reference signal, whether the UE group is awake at the PO.

The transmission resources of the reference signal may be used to indicate UE groups, that is, the transmission resources of the reference signal may indicate which groups of UEs receive the reference signal. For example, one transmission resource may correspond to one UE group, and one transmission resource may also correspond to multiple UE groups. Here, the transmission resources may be time domain resources, frequency domain resources and/or code domain resources of reference signals.

Exemplarily, the UEs within the coverage of the base station may be divided into a first UE group, a second UE group, a third UE group and a fourth UE group. The transmission resources of the reference signals corresponding to each UE group are different. When instructing the UE to monitor the reference signal, the UE may monitor the reference signal on the UE group to which the UE belongs, such as the transmission resource corresponding to the first UE group.

Exemplarily, a transmission resource may have a corresponding relationship with group identifiers of one or more UE groups.

In one embodiment, the method further includes: grouping the UE based on the identity of the UE.

The identity of the UE includes but is not limited to the International Mobile Mobile Subscriber Identity IMSI, the Temporary Mobile Subscriber Identity TMSI, and the like. A remainder operation may be performed on the identity of the UE, and a grouping may be determined based on the remainder.

For example, if the UEs need to be divided into M groups, where M is a positive integer greater than or equal to 2, the identifier of the UE can be divided by M, and the UEs with the same remainder are divided into the same group.

The base station may indicate, to UEs of different groups, the transmission resources of the reference signals of each UE group by using the configuration information of the reference signals. The transmission resources of the reference signal include, but are not limited to, frequency domain resources and/or time domain resources of the reference signal, and the like.

The UE may receive reference signals from transmission resources associated with its own group according to the UE group to which it belongs, and determine the state of the PEI according to the reference signals received by different transmission resources. For example, the transmission resource corresponding to the UE in the first UE group is the first type of transmission resource, and the transmission resource corresponding to the UE in the second UE group is the second type of transmission resource. When the reference signal uses the first type of transmission resource, the first type of transmission resource The UEs in the UE group receive the reference signal, while the UEs in the second UE group do not receive the reference signal.

In this way, the UE group that receives the reference signal is indicated by the transmission resource, that is, indicating which groups the UE monitors the reference signal, the UE determines the PEI according to the monitoring result of the reference signal, and the UE can determine whether to wake up based on the received PEI. Implementing PEI to perform PO wake-up indication based on UE grouping, reducing the false wake-up of the UE caused by all UEs using the same PEI, thereby reducing the power consumption of the UE.

Here, the PEIs of different UE groups can be indicated by reference signals of different time domain resources; the PEIs of different UE groups can also be indicated by reference signals of different frequency domain resources; the PEIs of different UE groups can also be indicated by reference signals of different frequency domain resources; The reference signals indicate PEIs of different UE groups. Different frequency domain resources may include different PRBs and the like. Different frequency domain resources may include different time slots and so on.

In one embodiment, different time domain resources may be different symbols occupied by reference signals.

Exemplarily, the reference signal may be TRS. The transmission resources occupied by the TRS may be as shown in FIG. 3 . One TRS may occupy two consecutive time slots (slots) in the time domain, and may occupy 52 PRBs in the frequency domain. The schematic diagram of transmission resources shown in FIG. 3 only shows part of the PRBs occupied by the transmission resources of one TRS. In FIG. 3 , the horizontal direction represents the time domain, and the vertical direction represents the frequency domain. Among them, one time slot has 14 symbols, which are represented by 0 to 13 in FIG. 3 . The transmission resources of one TRS occupy two symbols in one time slot, and are separated by three PRBs in the frequency domain. In FIG. 3 , the shaded square where "1" is located represents multiple REs occupied by transmission resources of one TRS, where "1" represents the location of REs occupied by transmission resources of one TRS.

Taking Figure 3 as an example, the transmission resources of a TRS occupy 4 and 8 of the first time slot in the time domain, and 4 and 8 of the second time slot, a total of 4 symbols, occupying the frequency domain of each symbol in the frequency domain. 3 REs with position "1". Since FIG. 3 only shows a part of the 52 PRBs, the actual number of REs occupied by the TRS on each symbol is greater than 3.

In one embodiment, in response to the time domain resource of the reference signal being used to indicate the UE group receiving the reference signal, a time domain resource of the reference signal is used to indicate the i UEs grouped by UEs receive the reference signal, where i is a positive integer greater than or equal to 1 and less than or equal to 1, where I is the total number of UE groups, and I is a positive integer.

Here, the reference signal of one time domain resource may indicate the PEI of one or more UE groups. The UE groups indicated by the different time domain resources may be determined through the provisions of the communication protocol and/or the manners negotiated by the base station and the UE.

As shown in FIG. 3 , the transmission resources of the TRS may occupy 4 and 8 symbols in each time slot, respectively. The transmission resources of the TRS may also occupy two symbols of 5 and 9. In this way, two TRSs occupying different time domain resources are generated. TSRs for different time domain resources may indicate PEIs for different UE groups.

UEs in different UE groups may determine their own time domain resources based on their own UE groups, monitor TRS on the respective time domain resources, and then determine their own PEIs.

Here, a reference signal of a frequency domain resource may indicate the PEI of one or more UE groups. The UE grouping indicated by the different frequency domain resources may be determined through a communication protocol specification and/or a manner negotiated by the base station and the UE.

Exemplarily, the reference signal may be TRS. In the schematic diagram of the transmission resource of the TRS as shown in FIG. 3 , “1” indicates that the transmission resource of the TRS occupies the RE at the first frequency domain position.

The frequency domain resources of the TRS can be configured in units of REs, and different frequency domain resources are occupied by configuring different frequency domain positions of the REs. For example, the frequency domain resource shown in FIG. 3 may be configured, wherein the RE of each symbol occupies the first frequency domain position. The frequency domain resources shown in FIG. 4 may also be configured. In FIG. 4 , the REs on the four symbols occupy the first frequency domain position, the second frequency domain position, the third position and the fourth frequency domain position respectively. In this way, in the case of the same symbol, transmission resources with different frequency domain positions are obtained. In Fig. 4, "1" indicates that the transmission resources of TRS occupy REs in the first frequency domain position, "2" indicates that the transmission resources of TRS occupy REs in the second frequency domain position, and "3" indicates that the transmission resources of TRS occupy the third frequency domain RE in the domain position, "4" indicates that the transmission resource of the TRS occupies the RE in the fourth frequency domain position. In this way, by shifting, TRSs transmitted through different frequency domain resources are obtained.

Exemplarily, the first transmission resource of the TRS shown in FIG. 3 may indicate one UE group. The second transmission resource of the TRS shown in FIG. 4 may indicate another UE grouping.

The predetermined symbol positions may include, but are not limited to, two or more symbols occupied by the TRS. The predetermined symbol positions may be negotiated with the UE through a communication protocol, or the base station.

For example, the predetermined symbol positions may be all symbols occupied by the TRS. As shown in FIG. 3 , the transmission resources of the TRS occupy the RE in the first frequency domain position in the four symbol time domain positions, and the TRS is used to indicate the PEIs of all UEs. In the same way, at the four symbol time domain positions of the TRS transmission resources, all occupy the REs in the second frequency domain position, or all occupy the REs in the third frequency domain position, or all occupy the REs in the fourth frequency domain position, Then the PEI indicated by the TRS can be used to instruct all UEs to sleep or wake up in PO.

When the UE receives the TRS that occupies the same RE in the 4-symbol position time domain, it can be determined that the TRS indicates the UE's own PEI.

For example, the predetermined symbol positions may be all symbols occupied by the TRS. As shown in Figure 4, the transmission resources of the TRS occupy the 4-symbol time domain positions, occupying the REs in the first frequency domain position, the second frequency domain position, the third frequency domain position and the fourth frequency domain position, respectively. Used to indicate the PEI of all UEs.

When the UE receives the TRS using REs occupying different frequency domain positions at four symbol positions, it can be determined that the TRS indicates the PEI of the UE itself.

In practical applications, the UE group indicated by the TRS may be determined in the same manner as stipulated in the communication protocol and/or negotiated by the base station and the UE under different RE occupancy conditions. As shown in Table 1, TRS occupying different REs can be used to indicate different UE groups. Among them, in the column of the frequency domain position of the RE, each number in "1111" and "1234" indicates the frequency domain position of the RE respectively occupied by the TRS at the four symbol positions.

In one embodiment, the using a reference signal to indicate the PEI includes:

The state of the PEI may include: a true state and a false state. The true state is used to indicate that the UE receives paging associated information at a predetermined PO. The fales state is used to indicate that the UE does not receive the information associated with the paging at the predetermined PO; the UE can keep the dormant state at the PO.

The coding form or information contained in the reference signal is usually fixed, so the reference signal cannot use numerical information to represent different states of different PEIs. Here, the different states of the reference signal are used to indicate the different states of the PEI. The status of the reference signal may include, but is not limited to, transmitted reference signals and untransmitted reference signals.

The base station indicates different states of PEI by whether to send a reference signal on the scheduled frequency domain resources.

The PEI may indicate whether the UE wakes up at one or more POs. For example, it may indicate that the UE wakes up at one or more predetermined POs. The predetermined POs may include but are not limited to: one or more POs after the time domain position of the PEI. For example, the predetermined PO may be the first PO after the PEI time domain location. The predetermined PO may be specified by a communication protocol, or negotiated by the base station and the UE, or the like.

The first state of the PEI may be the true state, and the second state of the PEI may be the fales state.

When the base station uses the scheduled frequency domain resource to send the reference signal, and the UE receives the reference signal through the frequency domain resource, the UE can determine that the PEI is in the first state, and the UE can receive paging associated information at a predetermined PO.

When the base station does not send a reference signal on the scheduled frequency domain resource and the UE does not receive a reference signal on the scheduled frequency domain resource, the UE may determine that the PEI is in the second state, and the UE may determine to maintain a sleep state at a predetermined PO.

Exemplarily, the base station configures the transmission resources described in FIG. 3 for transmitting TRS. The base station may configure the transmission resource to indicate one UE group or multiple UE groups, for example, the base station may configure the transmission resource to indicate the first UE group. The base station can send the TRS through the transmission resource. If the UE in the first UE group receives the TRS at the transmission resource, it determines that the PEI is in the first state. The base station may also not send the TRS in the transmission resource. If the UE in the first UE group does not receive the TRS on the transmission resource, it is determined that the PEI is in the second state.

When the base station does not send a reference signal on the scheduled frequency domain resource and the UE does not receive a reference signal on the scheduled frequency domain resource, the UE may determine that the PEI is in the first state, and the UE may determine to maintain a sleep state at a predetermined PO.

When the base station uses the scheduled frequency domain resource to send the reference signal, and the UE receives the reference signal through the frequency domain resource, the UE may determine that the PEI is in the second state, and the UE may receive paging associated information at a predetermined PO.

As shown in FIG. 5 , this exemplary embodiment provides a PEI indication method, and the PEI indication method can be applied to a UE of a cellular mobile communication system, including:

Step 501: Determine the transmission resource of the reference signal of the UE based on the UE grouping of the UE;

Step 502: Determine the PEI of the UE based on the monitoring result of the transmission resource.

In one embodiment, the reference signal includes: TRS and/or CSI-RS.

The transmission resources of the reference signal may be used to indicate UE groups, that is, the transmission resources of the reference signal may indicate which groups of UEs receive the reference signal. That is, the transmission resource of the reference signal may indicate the recipient of the reference signal. Different transmission resources may indicate different UE groups. For example, one transmission resource may correspond to one UE group, and one transmission resource may also correspond to multiple UE groups. Here, the transmission resources may be time domain resources, frequency domain resources and/or code domain resources of reference signals.

The UE may receive reference signals from the transmission resources associated with its own group according to the UE group to which it belongs, and determine the state of the PEI according to the reference signals received by different transmission resources. . For example, the transmission resource corresponding to the UE in the first UE group is the first type of transmission resource, and the transmission resource corresponding to the UE in the second UE group is the second type of transmission resource. When the reference signal uses the first type of transmission resource, the first type of transmission resource The UEs in the UE group receive the reference signal, while the UEs in the second UE group do not receive the reference signal.

Exemplarily, the reference signal may be TRS. The transmission resources occupied by the TRS may be as shown in FIG. 3 . One TRS may occupy two consecutive time slots (slots) in the time domain, and may occupy 52 PRBs in the frequency domain. The schematic diagram of transmission resources shown in FIG. 3 only shows part of the PRBs occupied by the transmission resources of one TRS. In FIG. 3 , the horizontal direction represents the time domain, and the vertical direction represents the frequency domain. Among them, one time slot has 14 symbols, which are represented by 0 to 13 in FIG. 3 . The transmission resources of one TRS occupy two symbols in one time slot, and are separated by three PRBs in the frequency domain. In Fig. 3, the shaded square where "1" is located represents multiple REs occupied by transmission resources of one TRS, wherein "1" represents the location of REs occupied by transmission resources of one TRS.

In one embodiment, in response to the frequency domain resource of the reference signal being used to indicate the UE group receiving the reference signal, a frequency domain resource of the reference signal is used to indicate the n number of the UE groups, where n is a positive integer greater than or equal to 1 and less than or equal to N, where N is the total number of UE groups, and N is a positive integer.

Here, the reference signal of one frequency domain resource may indicate the PEI of one or more UE groups. The UE grouping indicated by the different frequency domain resources may be determined through a communication protocol specification and/or a manner negotiated by the base station and the UE.

In one embodiment, the determining the frequency domain resources of the reference signal of the UE based on the UE grouping of the UE includes:

For example, the predetermined symbol positions may be all symbols occupied by the TRS. As shown in FIG. 3 , the transmission resources of the TRS occupy the REs in the first frequency domain position in the four symbol time domain positions, and the TRS is used to indicate the PEIs of all UEs. In the same way, at the four symbol time domain positions of the TRS transmission resources, all occupy the REs in the second frequency domain position, or all occupy the REs in the third frequency domain position, or all occupy the REs in the fourth frequency domain position, Then the PEI indicated by the TRS can be used to instruct all UEs to sleep or wake up in PO.

When the UE receives a TRS that occupies the same RE at four time-domain symbol positions, it can be determined that the TRS indicates the UE's own PEI.

For example, the predetermined symbol positions may be all symbols occupied by the TRS. As shown in Figure 4, the transmission resources of the TRS occupy the 4-symbol time domain positions, occupying the REs in the first frequency domain position, the second frequency domain position, the third frequency domain position and the fourth frequency domain position, respectively. Used to indicate the PEI of all UEs. .

Taking Fig. 4 and the frequency domain position "1234" of RE in Table 1 as an example, "1" in "1234" indicates that on symbol 4 of time slot 1, the RE occupies the first frequency domain position, "1234" "2" in "2" indicates that on symbol 8 of time slot 1, the RE occupies the second frequency domain position, "3" in "1234" indicates that on symbol 4 of time slot 2, the RE occupies the third frequency domain position, in "1234" "4" indicates that on symbol 8 of time slot 2, the RE occupies the fourth frequency domain position. In one embodiment, the determining the PEI of the UE based on the monitoring result of the transmission resource includes:

Exemplarily, the base station configures the transmission resources described in FIG. 3 for transmitting TRS. The base station may configure the transmission resource to indicate one UE group or multiple UE groups, for example, the base station may configure the transmission resource to indicate the first UE group. The base station can send the TRS through the transmission resource. If the UE in the first UE group receives the TRS at the transmission resource, it determines that the PEI is in the first state. The base station may also not send the TRS in the transmission resource. If the UE in the first UE group does not receive the TRS in the transmission resource, it is determined that the PEI is in the second state.

A specific example is provided below in conjunction with any of the above-mentioned embodiments:

2. The base station groups UEs according to the frequency domain configuration based on TRS/CSI-RS. As shown in FIG. 3 , when no grouping is required or more than one group of UEs have paging, the base station sends the resource of the default frequency domain RE position 1.

3. When a group of UEs are paging, receive TRS/CSI-RS according to the frequency domain position corresponding to the group code. As shown in Figure 4, different shifted pattern formats represent different UE groups.

4. As shown in Figure 3 and Figure 4, a symbol has 4 frequency domain positions that can be shifted, and there are a total of 4 symbols at the same time. Therefore, there are 4 to the 4th power in total, that is, 256 different transmission resources. For example, for 16 UE groups, 16 different transmission resource indications may be used. Using the TRS of the transmission resource as shown in FIG. 3 can be used to indicate that all UEs receive the paging message.

5. The UE groups indicated by different transmission resources can be preset, as shown in Table 1.

6. The base station can configure the two states of TRS to indicate the two states of PEI respectively, or specify/configure one of the states:
