Detailed ways

The following describes in detail the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to be used to explain the present application, but should not be construed as a limitation to the present application.

FIG. 1 is a schematic flowchart of a method for acquiring a short message according to an embodiment of the present application. As shown in Figure 1, executed by user equipment (User Equipment, UE for short), the short message acquisition method includes the following steps:

Step 101: Obtain a paging advance indication PEI and a short message at the same paging occasion PO, where the PEI is used to indicate whether the UE needs to monitor the paging message on one or more subsequent POs.

It should be noted that, with the enhancement of technology, a paging early indication (PEI for short) is introduced into the existing protocol. Since the PEI is likely to be sent on a certain advance paging occasion (Paging Occasion, PO for short), the UE needs to monitor the PEI sent on the advance PO.

Therefore, based on the fact that the terminal must monitor the PO in advance, the short message acquisition method proposed in this application can acquire the short message (Short Message) while monitoring the PEI in the PO in advance.

In some embodiments of the present application, taking the R17 version standardization work as an example, in order to save the energy consumption of the terminal in the RRC-IDLE (Radio Resource Control-IDLE, radio resource control idle) state, that is, the RRC idle state, The base station can send PEI for the terminal. Correspondingly, the terminal can monitor the PEI sent by the base station and acquire short messages at the same time. Of course, with the development of communication technologies, PEI can be sent in any appropriate state. Therefore, the PEI in this embodiment of the present application is not limited to being sent only in the RRC-IDLE state, and can also be sent in other states. For example, RRC-INACTIVE (Radio Resource Control-INACTIVE, radio resource control activation) state.

The PEI may be used to indicate whether the UE needs to monitor a paging message on one or more subsequent paging occasions PO.

Among them, the paging message can be carried in the Physical Downlink Shared Channel (PDSCH for short), and needs to be scheduled by the paging scrambling control signaling (paging Downlink Control Information, referred to as paging DCI). Scheduled by DCI scrambled by P-RNTI.

Wherein, the short message can be carried by paging DCI, and the content carried in the short message can exemplarily include one or more of the following information: system information update reminder, emergency disaster avoidance information, etc.; and the short message can be directly carried In paging DCI, there is no need to schedule PDSCH for bearer.

Among them, PO refers to the timing for transmitting paging DCI. For a UE, the corresponding PO occurs periodically, and multiple UEs may use the same set of periodic PO resources, that is, paging messages of multiple UEs may appear in one PO.

In the embodiment of the present application, the acquisition of short messages while monitoring the paging advance indication PEI can be implemented by various technical solutions, for example: both the short message and the PEI are carried by the paging DCI; or the short message and the PEI are carried on the in different DCIs; et al. For example: short message is carried in paging DCI, while PEI is carried in other DCI. In the embodiment of the present application, the acquisition of the short message while monitoring the paging advance indication PEI means that the UE receives the acquisition of the PEI and the short message in the same PO, and the PEI and the short message are transmitted in the same PO.

According to a method for acquiring a short message in an embodiment of the present application, a user equipment can acquire a short message by monitoring a paging advance indication PEI, where the PEI is used to indicate whether the UE needs to monitor on one or more subsequent paging occasions PO. Paging messages to achieve short message acquisition. The above embodiment no longer adopts the method of receiving short messages after the UE wakes up and receives the PEI, and then waits until the corresponding PO arrives to receive short messages. By saving the energy consumption of the UE when the UE remains awake or in a light sleep state, the short message can be achieved in a short time. The purpose of saving energy in the process of message acquisition. In some possible implementations, after the UE is woken up and receives the PEI, it needs to stay in the wake-up state or the light sleep state, so as to continue to receive short messages when the corresponding PO arrives.

It should be noted that, in the related art, after the UE wakes up and receives the PEI, and then waits until the corresponding PO arrives, the short message is received in the UE, so as to obtain the short message.

The following explains the process of the UE monitoring the paging message and determining the time domain position of the PO corresponding to itself.

It should be noted that when the terminal and other UEs are in the RRC-IDLE state, that is, the RRC idle state, or in the RRC-INACTIVE state, that is, the RRC inactive state, the main behavior of the UE is to periodically monitor the paging messages, and when receiving After the paging message, it enters RRC-CONNECTED, ie RRC connected state, for normal communication. Among them, the paging message is carried in the PDSCH and needs to be scheduled by the DCI scrambled by the P-RNTI, that is, the paging DCI. In this case, for a UE, its corresponding PO occurs periodically, and multiple UEs may use the same set of periodic PO resources, that is, paging messages of multiple UEs may appear in one PO.

In the relevant communication protocol, the UE can monitor the paging message through the following operations: the UE monitors whether there is DCI scrambled with P-RNTI in its corresponding PO, scrambled DCI, and the DCI schedules the PDSCH containing the paging message, in this case, the UE can receive and demodulate the PDSCH according to the indication of the DCI; However, the DCI does not schedule the PDSCH containing the paging message. In this case, the UE may not receive and demodulate the PDSCH. Of course, no matter whether the PDSCH carrying the paging message is scheduled or not, the paging DCI can carry the short message.

Further, the UE can determine the time domain position of the PO corresponding to it, and then blindly checks whether there is a corresponding Paging DCI in the PO corresponding to it.

Optionally, when trying to determine the time domain position of the PO corresponding to the UE, the SFN (system frame number, system frame number) of the PF (paging frame, paging frame) where the PO is located, and the index of the PO in the PF can be used. , and determine the time domain position of the PO corresponding to the UE. Wherein, in a PF, there may be one or more POs, and their indices can be numbered from a preset number, such as 0.

In the relevant communication protocol, the formula for the UE to determine the SFN of the PF where the corresponding PO is located is as follows:

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

In the relevant communication protocol, the formula for the UE to determine the PO index in the PF where the corresponding PO is located is as follows:

i_s=floor(UE_ID/N)mod Ns

Among them, T is the paging cycle of the UE, in frames, N is the number of PFs in a paging cycle, Ns is the number of POs in a PF, and PF_offset is the time domain offset of the PF frame, in frames as unit. The above parameters can be configured by the base station through broadcast messages.

Further, the terminal may respond to the indication of the PEI to determine whether to monitor the paging DCI.

However, if the UE does not actually have a paging message and only needs to receive short messages, in this case, after the UE wakes up and receives the PEI, it waits for the arrival of its corresponding PO, and then goes to receive short messages. In this way, the short message acquisition method in the related art will inevitably lead to a technical problem of not saving energy.

Therefore, in the present application, short messages can be acquired while monitoring the paging advance indication PEI, and by saving the energy consumption when the UE remains awake or in a light sleep state, the purpose of saving energy consumption in the process of acquiring short messages is achieved.

FIG. 2 is a schematic flowchart of another method for acquiring a short message according to an embodiment of the present application.

As a possible implementation, as shown in Figure 2, on the basis of the above-mentioned embodiment, the specific process of acquiring PEI and short message in the same PO in the above-mentioned steps includes the following steps:

Step 201: Monitor the PEI on the mth paging occasion PO of the ith system frame.

In some embodiments of the present application, the PEI may be carried in the paging DCI sent on the mth PO, and the PEI may also be carried in other DCIs different from the paging DCI sent on the mth PO. Therefore, in the present application, the PEI can be monitored for different bearer locations of the PEI.

The following describes the process of monitoring the PEI with respect to different bearer locations of the PEI.

For the paging DCI carried by the PEI and sent on the m-th PO, the paging DCI sent on the m-th PO of the i-th system frame can be monitored, and the PEI can be obtained from the monitored paging DCI.

For other DCIs different from the paging DCI that are carried by the PEI and sent on the m-th PO, other DCIs sent on the m-th PO of the i-th system frame can be monitored, and the PEI can be obtained from the monitored paging DCI.

Step 202: Acquire a short message from the paging scramble control signaling paging DCI sent on the m-th PO of the i-th system frame.

It should be noted that different DCI formats, such as DCI 1-0, DCI 1-1, etc., can be used to implement different functions. Taking the 5G NR system as an example, DCI format 1_0 can be used to schedule paging information. In this case, when DCI format 1_0 is used for scheduling paging information, some bits (bits) in the information field of DCI are in a reserved state, and the reserved bits are not used for any purpose.

For example, when the Short Messages Indicator (Short Messages Indicator) information field in DCI format 1-0 indicates "there is no short message, but there is paging information", the 8 bits of the short message information field will be reserved.

In some embodiments of the present application, reserved bits in the information field of paging DCI are used to carry short messages.

For example, for UE A, its corresponding PO is in PO n of SFN j. According to the related art, the PEI corresponding to UE A may be sent in PO m of SFN i. In this case, the PO m of SFN i is ahead of the PO n of SFN j in time, and the PO m of SFN i is generally the PO of other UEs, such as the PO of UE B. Among them, PEI may send a single DCI in PO m of SFN i, or it may be carried on the reserved bit of paging DCI sent in PO m of SFN i.

FIG. 3 is a schematic flowchart of another method for acquiring a short message according to an embodiment of the present application.

As a possible implementation, as shown in Figure 3, on the basis of the above-mentioned embodiment, the specific process of obtaining PEI and short message in the same PO in the above-mentioned steps includes the following steps:

Step 301: Monitor the PEI on the mth paging occasion PO of the ith system frame.

Optionally, if the PEI is carried in the paging DCI sent on the mth PO, then the paging DCI sent on the mth PO of the ith system frame can be monitored, and the PEI can be obtained from the monitored paging DCI.

Optionally, if the PEI is carried in other DCIs sent on the mth PO that are different from the paging DCI, other DCIs sent on the mth PO of the ith system frame can be monitored, and obtained from the monitored paging DCI. PEI.

Step 302: Acquire a short message from the paging scramble control signaling paging DCI sent on the mth PO of the ith system frame.

It should be noted that, after acquiring the short message, the UE may respond to different PEIs to indicate whether the UE has a paging message that needs to be monitored according to the PEI.

As a possible implementation, if the UE instructs the UE to monitor the paging DCI on the target PO corresponding to itself in response to the PEI, in this case, the UE can keep a dormant state to monitor the paging message before reaching the target PO; The PEI indicates that the UE has no paging messages to monitor, then it reaches the target PO and does not monitor the paging DCI sent on the target PO.

According to a method for acquiring a short message according to an embodiment of the present application, after acquiring the short message, the user equipment can respond to different indications from the PEI, and when the PEI indicates that the UE has no paging messages to monitor, the user equipment can reach the target PO without noticing the target. The paging DCI sent on the PO is monitored to avoid unnecessary power consumption when waking up the software and hardware for synchronization and other operations, so as to achieve the purpose of saving energy consumption in the process of acquiring short messages.

To sum up, since the UE needs to wake up in advance and needs to perform synchronization, and after reaching a certain synchronization accuracy, it can successfully receive PEI information in the PO m of SFN i. At the same time, since the short message is a common message of the whole cell, different UEs in the cell can share the message. Therefore, it is feasible for the UE to blindly detect the paging DCI in the PO m of SFN i and obtain the short message carried in the paging DCI. It is not necessary to wait until the PO corresponding to the UE (that is, the PO n of the SFN j) to blindly detect the paging DCI again. DCI to get short messages. In this way, the energy consumption of the UE to keep awake/light sleep during the period from PO m of SFN i to PO n of SFN j can be saved. Further, the UE only needs to perform blind detection (blind detection PEI/Paging DCI) in PO m of SFN i, and does not need to perform blind detection in PO m (blind detection PEI) of SFN i and PO n (blind detection Paging detection) of SFN j. Blind detection is performed in DCI), which saves the energy consumption of blind detection.

Step 401: Determine the resources for sending a paging advance indication PEI and a short message in the same paging opportunity PO, wherein the PEI is used to indicate whether the receiving end needs to monitor the paging message on one or more subsequent POs.

In this embodiment of the present application, a network side device such as a base station can determine resources for sending a paging advance indication PEI and a short message in the same paging occasion PO. Correspondingly, a UE such as a terminal can obtain a paging advance indication PEI and a short message in the same paging occasion PO.

According to a method for acquiring a short message in an embodiment of the present application, the network side device can acquire the short message by determining the resources for sending the paging advance indication PEI and the short message in the same paging occasion PO. The above embodiment no longer adopts the method of receiving short messages after the UE wakes up and receives the PEI, and then waits until the corresponding PO arrives to receive short messages. By saving the energy consumption of the UE when the UE remains awake or in a light sleep state, the short message can be achieved in a short time. The purpose of saving energy in the process of message acquisition. In some possible implementations, after the UE is woken up and receives the PEI, it needs to stay in the wake-up state or the light sleep state, so as to continue to receive short messages when the corresponding PO arrives.
