The execution subject that this disclosed embodiment relates to includes but not limited to: a UE such as a mobile phone terminal supporting cellular mobile communication, and a base station.

An application scenario of the embodiment of the present disclosure is that a Paging Early Indication (PEI) may be used to indicate whether there is a paging message of a UE in a PO behind the PEI. If there is no paging message of the UE in the PO, the UE can keep a sleep state at the PO location, thereby achieving the effect of saving power. How to indicate PEI to the UE is an urgent issue to be solved.

As shown in fig. 2, the present exemplary embodiment provides a PEI indication method, where the PEI indication method may be applied in a base station of a cellular mobile communication system, and the method includes:

step 201: and indicating the PEI by using the reference signal, wherein the transmission resource of the reference signal is used for indicating the UE groups receiving the reference signal, namely indicating which UE groups receive the reference signal.

The reference signals of different transmission resources are adopted to indicate the UE of different groups to receive the corresponding reference signals. If the reference signal of the first transmission resource is adopted to indicate that the UE of the group 1 and the UE of the group 2 receive the reference signal; the reference signal using the second transmission resource indicates the UE of packet 3 to receive the reference signal. Different transmission resources occupy different time domains and/or different frequency domain locations.

Here, the UE may be a mobile phone terminal or the like that performs wireless communication using a cellular mobile communication technology. The base station may be a communication device providing an access network interface to the 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 downlink synchronization by the UE. The signal configuration information may be used to indicate a configuration of the reference signal, such as a transmission resource configuration of the reference signal.

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

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

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

The base station will typically configure a set of signal configuration information for TRSs and/or CSI-RS 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 the idle UEs and/or the inactive UEs through system information and the like.

The PEI can be carried by reference signals such as TRS and/or CSI-RS. The PEI may indicate two states with and without paging messages in the PO, and the UE may wake up or stay dormant in the PO according to the PEI's indication. The two states of the PEI may be characterized by different coding of the reference signals, transmission resources, etc.

If all the UE receives paging information at the PO based on the indication of the same PEI, the probability that the UE is mistakenly awakened is improved, and then the power consumption of the UE is improved.

The UEs may be divided into a plurality of UE groups, for example, UEs within the coverage of the base station may be divided into 4 UE groups or 16 UE groups, etc. Different PEI's are associated with 1 or more UE grouped UEs. I.e. one PEI may instruct 1 packet UE or multiple packet UEs to listen for paging messages at the PO or stay dormant at the PO. The UE may determine whether to wake up a group of UEs at the PO based on the PEI indicated by the received reference signal.

The UE packets may be indicated with the transmission resources of the reference signal, i.e. the transmission resources of the reference signal may indicate which of the grouped UEs receive the reference signal. For example, one transmission resource may correspond to one UE packet, and one transmission resource may also correspond to a plurality of UE packets. Here, the transmission resources may be time domain resources, frequency domain resources, and/or code domain resources of the reference signal.

For example, 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 the UE is instructed to monitor the reference signal, the UE may monitor the reference signal on a transmission resource corresponding to a UE group to which the UE belongs, for example, a first UE group.

For example, a transmission resource may have a correspondence with a group identity of one or more UE groups.

In one embodiment, the method further comprises: grouping the UEs based on the identities of the UEs.

The identity of the UE includes, but is not limited to, international mobile subscriber identity IMSI, temporary mobile subscriber identity TMSI, etc. A remainder operation may be performed on the UE's identity, and the grouping may be determined based on the remainder.

As an example, if it is desired to group UEs into M groups, where M is a positive integer greater than or equal to 2, the identity of the UE may be divided by M, and UEs of the same remainder may be grouped into the same group.

The base station can indicate the transmission resources of the reference signals of each UE group to the UEs of different groups through 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, etc.

The UE can receive the reference signal from the transmission resource associated with the UE group according to the UE group to which the UE belongs, and determine the state of the PEI according to the reference signal received by different transmission resources. For example, the transmission resource corresponding to the UE of the first UE group is a first transmission resource, the transmission resource corresponding to the UE of the second UE group is a second transmission resource, and when the reference signal adopts the first transmission resource, the UE of the first UE group receives the reference signal, but the UE of the second UE group does not receive the reference signal.

In this way, the UE group receiving the reference signal is indicated by the transmission resource, that is, the UE in which group is indicated 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. The PO awakening indication of the PEI based on the UE grouping is realized, the condition that all the UEs adopt the same PEI and are awakened by mistake is reduced, and further the power consumption of the UEs is reduced.

Here, PEI of different UE groups may be indicated by reference signals of different time domain resources; the PEI of different UE groups may also be indicated by reference signals of different frequency domain resources; the PEI of different UE groups may also be indicated by reference signals with different frequency domain resources and time domain resources. Different frequency domain resources may comprise different PRBs, etc. Different frequency domain resources may comprise different time slots, etc.

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

Illustratively, the reference signal may be a TRS. The transmission resources occupied by the TRS may be as shown in fig. 3, where one TRS may occupy two consecutive slots (slots) in the time domain and may occupy 52 PRBs in the frequency domain. The transmission resource diagram shown in fig. 3 only shows a part of PRBs occupied by the transmission resource of one TRS, where the horizontal direction in fig. 3 represents a time domain and the vertical direction represents a frequency domain. One slot has 14 symbols, and is represented by 0 to 13 in fig. 3. The transmission resource of one TRS occupies 2 symbols in one slot, and is spaced by 3 PRBs in the frequency domain. In fig. 3, a hatched square where "1" is located indicates a plurality of REs occupied by the transmission resource of one TRS, where "1" indicates a position of an RE occupied by the transmission resource of one TRS.

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

In one embodiment, in response to the time domain resource of the reference signal indicating the UE packet receiving the reference signal, a time domain resource of the reference signal indicating that I UEs of the UE packets receive the reference signal, wherein I is a positive integer greater than or equal to 1 and less than or equal to I, where I is the total number of the UE packets and I is a positive integer.

Here, the reference signal of one time domain resource may indicate PEI of 1 or more UE groups. The UE packets indicated by the different time domain resources may be determined by communication protocol specification and/or by way of agreement between the base station and the UE.

As shown in fig. 3, the transmission resource of the TRS may occupy 4 and 8 symbols on each slot. The transmission resource of the TRS may also occupy two

symbols

5 and 9. In this manner, two TRSs are generated that occupy different time domain resources. The TSRs of different time domain resources may indicate PEI for different groups of UEs.

The UE in different UE groups can determine respective time domain resources based on the UE groups, monitor TRS on the respective time domain resources, and further determine respective PEI.

Here, a reference signal of one frequency domain resource may indicate PEI of 1 or more UE groups. The UE packets indicated by the different frequency domain resources may be determined by communication protocol specification and/or by way of agreement between the base station and the UE.

Illustratively, the reference signal may be a TRS. As in the transmission resource diagram of the TRS shown in fig. 3, "1" indicates that the transmission resource of the TRS occupies an RE at the 1 st frequency domain position.

The frequency domain resources of the TRS may 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 resources shown in fig. 3 may be configured, where REs of each symbol occupy the 1 st frequency domain position. The frequency domain resources shown in fig. 4 may also be configured, and in fig. 4, REs on 4 symbols occupy the 1 st frequency domain position, the 2 nd frequency domain position, the 3rd position, and the 4th frequency domain position, respectively. Thus, under the condition of the same symbol, transmission resources with different frequency domain positions are obtained. In fig. 4, "1" indicates that the transmission resource of the TRS occupies the RE at the 1 st frequency domain position, "2" indicates that the transmission resource of the TRS occupies the RE at the 2 nd frequency domain position, "3" indicates that the transmission resource of the TRS occupies the RE at the 3rd frequency domain position, and "4" indicates that the transmission resource of the TRS occupies the RE at the 4th frequency domain position. Thus, by shifting, TRSs transmitted through different frequency domain resources are obtained.

Illustratively, the first transmission resource of the TRS shown in fig. 3 may indicate one UE packet. The second transmission resource of the TRS shown in fig. 4 may indicate another UE group.

The predetermined symbol positions may include, but are not limited to: TRS occupies two or more symbols. The predetermined symbol position may be agreed upon with the UE through a communication protocol or a base station.

For example, the predetermined symbol position may be all symbols occupied by the TRS. As shown in fig. 3, the transmission resource of the TRS occupies the RE in the 1 st frequency domain position at all 4 symbol time domain positions, and the TRS is used to indicate PEI of all UEs. Similarly, on the 4 symbol time domain positions of the transmission resource of the TRS, the REs in the 2 nd frequency domain position, the REs in the 3rd frequency domain position, or the REs in the 4th frequency domain position are all occupied, so the PEI indicated by the TRS may be used to indicate all the UEs to sleep or wake up in the PO.

When the UE receives a 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 position may be all symbols occupied by the TRS. As shown in fig. 4, the transmission resource of the TRS occupies REs at the 1 st frequency domain position, the 2 nd frequency domain position, the 3rd frequency domain position and the 4th frequency domain position in 4 symbol time domain positions, respectively, and then the TRS is configured to indicate PEI of all UEs.

When the UE receives a TRS employing REs occupying different frequency domain positions at 4 symbol positions, respectively, it may be determined that the TRS indicates PEI of the UE itself.

In practical application, the UE groups indicated by the TRS under different RE occupation conditions may be determined in a manner specified by a communication protocol and/or agreed by the base station and the UE. As shown in table 1, TRSs occupying different REs may be used to indicate different UE groups. In the frequency domain position column of RE, each numeral in "1111" and "1234" etc. indicates the frequency domain position of RE occupied by TRS respectively at 4 symbol positions.

TABLE 1

In one embodiment, the indicating PEI with a reference signal comprises:

The state of the PEI may include: true (true) state and false (leaves) state. the tune state is used to indicate that the UE receives paging associated information at a predetermined PO. A fall state for indicating that the UE does not receive paging associated information at a predetermined PO; the UE may remain dormant at the PO.

The encoded form of the reference signal or the information contained therein is usually fixed, and the reference signal cannot represent different states of different PEI's with numerical information. Here, different states of the signal are referenced to indicate different states of the PEI. The state of the reference signal may include, but is not limited to, a transmitted reference signal and an untransmitted reference signal.

The base station indicates different states of the PEI by whether or not to transmit a reference signal on the scheduled frequency domain resources.

The PEI may indicate whether the UE wakes up at one or more POs, such as may indicate that the UE wakes up at a predetermined one or more POs, which may include but is not limited to: one or more POs after the PEI temporal location. For example, the predetermined PO may be the first PO after the PEI temporal location. The predetermined PO may be specified by a communication protocol, or agreed upon by the base station and the UE, etc.

The first state of PEI may be the tune state and the second state of PEI may be the falls state.

When the base station transmits the reference signal by using the scheduled frequency domain resource and the UE receives the reference signal through the frequency domain resource, the UE may determine that the PEI is in the first state and may receive paging related information at a predetermined PO.

When the base station does not send the reference signal on the scheduled frequency domain resource and the UE does not receive the 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 remain in the sleep state at the predetermined PO.

Illustratively, the base station configures the transmission resources described in fig. 3 for transmission of the TRS. The base station may configure the transmission resource to indicate 1 UE group or multiple UE groups, e.g., the base station may configure the transmission resource to indicate the first UE group. The base station may transmit the TRS through the transmission resource. The UEs of the first UE group receive the TRS at the transmission resource, and determine that the PEI is in the first state. The base station may not transmit the TRS at the transmission resource. And if the UE of the first UE group does not receive the TRS on the transmission resource, determining that the PEI is in the second state.

When the base station does not send the reference signal on the scheduled frequency domain resource and the UE does not receive the 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 that the UE remains in the sleep state at the predetermined PO.

When the base station transmits the reference signal by using the scheduled frequency domain resource 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 related information at a predetermined PO.

As shown in fig. 5, the present exemplary embodiment provides a PEI indication method, where the PEI indication method may be applied in a UE of a cellular mobile communication system, and the method includes:

step 501: determining a transmission resource of a reference signal of the UE based on a UE grouping of the UE;

step 502: and determining the PEI of the UE based on the monitoring result of the transmission resource.

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

The UE packets may be indicated with the transmission resources of the reference signal, i.e. the transmission resources of the reference signal may indicate which of the grouped UEs receive the reference signal. I.e., the transmission resources of the reference signal may indicate a reception object of the reference signal. Different transmission resources may indicate different UE groups. For example, one transmission resource may correspond to one UE packet, and one transmission resource may also correspond to a plurality of UE packets. Here, the transmission resources may be time domain resources, frequency domain resources, and/or code domain resources of the reference signal.

The UE can receive the reference signal from the transmission resource associated with the UE group according to the UE group to which the UE belongs, and determine the state of the PEI according to the reference signal received by different transmission resources. . For example, the transmission resource corresponding to the UE of the first UE group is a first transmission resource, the transmission resource corresponding to the UE of the second UE group is a second transmission resource, and when the reference signal adopts the first transmission resource, the UE of the first UE group receives the reference signal, but the UE of the second UE group does not receive the reference signal.

In one embodiment, the time domain resource of the reference signal is used for indicating the UE group, and the time domain resource of the reference signal is used for indicating I UE groups, wherein I is a positive integer greater than or equal to 1 and less than or equal to I, wherein I is the total number of the UE groups, and I is a positive integer.

symbols

In one embodiment, in response to the frequency domain resource of the reference signal indicating the UE packet receiving the reference signal, a frequency domain resource of the reference signal indicating N UE packets, where N is a positive integer greater than or equal to 1 and less than or equal to N, where N is a total number of the UE packets and N is a positive integer.

Here, the reference signal of one frequency domain resource may indicate PEI of 1 or more UE groups. The UE packets indicated by the different frequency domain resources may be determined by communication protocol specification and/or by way of agreement between the base station and the UE.

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

For example, the predetermined symbol position may be all symbols occupied by the TRS. As shown in fig. 4, the transmission resource of the TRS occupies REs at the 1 st frequency domain position, the 2 nd frequency domain position, the 3rd frequency domain position and the 4th frequency domain position in 4 symbol time domain positions, respectively, and then the TRS is configured to indicate PEI of all UEs. .

Further, taking fig. 4 and frequency domain position "1234" of the RE in table 1 as an example, "1" in "1234" represents on symbol 4 of slot 1, the RE occupies the 1 st frequency domain position, "2" in "1234" represents on symbol 8 of slot 1, the RE occupies the 2 nd frequency domain position, "3" in "1234" represents on symbol 4 of slot 2, the RE occupies the 3rd frequency domain position, "4" in "1234" represents on symbol 8 of slot 2, and the RE occupies the 4th frequency domain position. In one embodiment, the determining the PEI of the UE based on the listening result of the transmission resource includes:

Illustratively, the base station configures the transmission resources described in fig. 3 for transmission of the TRS. The base station may configure the transmission resource to indicate 1 UE group or multiple UE groups, e.g., the base station may configure the transmission resource to indicate the first UE group. The base station may transmit the TRS through the transmission resource. The UEs of the first UE group receive the TRS at the transmission resource, and determine that the PEI is in the first state. The base station may not transmit the TRS at the transmission resource. And if the UE grouped by the first UE does not receive the TRS in the transmission resource, determining that the PEI is in the second state.

One specific example is provided below in connection with any of the embodiments described above:

1. the base station indicates the UE grouping of Idle state (Idle) UE and/or inactive state (inactive) UE for receiving the paging according to the TRS/CSI-RS based transmission resource.

2. The base station groups the UEs according to the frequency domain configuration based on the TRS/CSI-RS, and sends the resource of the default frequency domain RE location 1 when the grouping is not needed or more than 1 group of UEs have paging as shown in fig. 3.

3. When there is a group of UEs having a page, the TRS/CSI-RS is received according to the frequency domain location corresponding to the block coding, as shown in fig. 4, different shift pattern (shifted pattern) formats represent different UE groups.

4. As shown in fig. 3 and 4, there are 4 frequency domain positions that can be shifted for one symbol, and there are 4 symbols in total, so there are 4 powers, i.e. 256 different transmission resources. For example, for 16 UE groups, 16 different transmission resource indications may be employed. A TRS employing transmission resources as in fig. 3 may be used to indicate that all UEs receive paging messages.

5. The UE groups indicated by different transmission resources may be preset as shown in table 1.

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

7. if the UE does not detect the TRS, the PEI does not transmit, and the UE wakes up to receive the paging information.

8. Or if the UE does not detect a TRS, the UE does not wake up. 7 and 8 depend on the configuration of the base station.

9. In the case of multiple sets of TRS transmission resources, at least one set of transmission resources may be used to apply the above method. If a plurality of sets of TRS transmission resources with different symbol positions are configured, at least one set of TRS transmission resources can be used to apply the method.
