Fig. 1 is a block diagram illustrating a communication system provided by an exemplary embodiment of the present disclosure, and as shown in fig. 1, the communication system may include: a network side 12 and a terminal 13.

Network side 12 includes several access network devices 120 therein. The access network equipment 120 may be a base station, which is a device deployed in an access network to provide wireless communication functions for terminals. The base station may be a base station of a serving cell of the terminal 13 or a base station of a serving cell adjacent to the serving cell of the terminal 13. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, Transmission Reception Points (TRPs), and the like. In systems using different radio access technologies, the names of devices having a base station function may be different, and in a 5G NR system, it is called a gbnodeb or a gNB. The name "base station" may describe, and may vary as communication technology evolves. Access network device 120 may also be a Location Management Function (LMF).

The terminal 13 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, as well as various forms of user equipment, Mobile Stations (MS), terminals, Internet of Things (IoT), industrial Internet of Things (Industry Internet of Things (liot), and so on. For convenience of description, the above-mentioned devices are collectively referred to as a terminal. The access network device 120 and the terminal 13 communicate with each other through some air interface technology, for example, a Uu interface.

In the standard discussion of the 5G NR R17 stage, a TRS/CSI-RS scheme for idle terminals is proposed. The TRS/CSI-RS is used for time-frequency synchronization and radio resource management measurement. Wherein the TRS comprises a plurality of periodically transmitted Non-Zero Power (NZP) CSI-RSs.

Besides, the TRS/CSI-RS may be set near a Paging Occasion (PO) for precise synchronization, that is, if the terminal detects the TRS/CSI-RS at a set position in front of the PO, it indicates that there is a Short Message (Short Message) or a Paging Message (Paging Message) in the PO, and the terminal is to continue to monitor the PO to obtain the Short Message or the Paging Message. If the terminal does not detect the TRS/CSI-RS before the PO, which means there is no short message or paging message for the terminal in the PO, the terminal does not need to listen to the PO.

When paging detection is carried out, paging grouping can also be carried out on the terminals, and the access network equipment indicates whether a group of terminals have short messages or paging messages through CSI-RS. For example, if the terminal determines that the location detects the CSI-RS before the PO, it indicates that there is a short message or a paging message of the group of terminals in the PO, the terminal further detects a Physical Downlink Shared Channel (PDSCH) in the PO, solves the terminal identifier in the message, if it is the terminal identifier of itself, it indicates that there is a short message or a paging message of itself, and if it is another terminal identifier in the group, it indicates that there is no short message or a paging message of itself.

Here, the paging packet may be performed using a CSI-RS sequence, and the greater the number of paging packets, the more power is saved for the terminal. But limited by the number of CSI-RS sequences, currently, the number of packets that can be based on CSI-RS sequences is small.

The communication system and the service scenario described in the embodiment of the present disclosure are for more clearly illustrating the technical solution of the embodiment of the present disclosure, and do not constitute a limitation to the technical solution provided in the embodiment of the present disclosure, and as a person having ordinary skill in the art knows that along with the evolution of the communication system and the appearance of a new service scenario, the technical solution provided in the embodiment of the present disclosure is also applicable to similar technical problems.

Fig. 2 is a flow chart illustrating a paging packet configuration method according to an example embodiment. Referring to fig. 2, the method comprises the steps of:

in step 101, the access network device acquires paging packet information.

The paging packet information is used to indicate a paging packet in which the terminal is located, where frequency domain offsets of reference signals of different paging packets are different, that is, in the embodiment of the present disclosure, the paging packet is implemented based on the frequency domain Offset of the reference signal, for example, frequency offsets (offsets) of Resource Elements (REs) transmitting the reference signals are different for different paging packets. One subcarrier in the frequency domain and one symbol (symbol) in the time domain are referred to as one RE.

The access network device may obtain the paging packet information through configuration information, protocol definition, or local storage, for example, the access network device may receive configuration information issued by other devices on the network side, where the configuration information carries the paging packet information; or, the paging packet information is configured in the local storage or protocol of the access network device, and the access network device may obtain the paging packet information from the protocol definition or local storage when in use.

In step 102, the access network equipment transmits the paging packet information.

In the embodiment of the disclosure, the access network device first acquires the paging packet information and then sends the paging packet information to the terminal, so that the terminal can perform paging detection based on the paging packet information. Because in the paging packet information, different paging packets are distinguished based on the frequency domain offset of the reference signal, compared with the CSI-RS sequence, more packets can be divided, so that the power consumption of the terminal in the paging detection process can be further reduced, and the power saving of the terminal is facilitated.

Optionally, the reference signal is a TRS/CSI-RS, that is, the reference signal may be a TRS or a CSI-RS.

Generally, an access network device may transmit a reference signal on one symbol of 1 Resource Block (RB).

As shown in fig. 3 to 5, a structure diagram of one RB includes 14 symbols in the time domain and 12 subcarriers in the frequency domain, and each small square represents 1 RE. The access network equipment may transmit the reference signal on one of the symbols, e.g., on symbol 3.

In the frequency domain, different paging packets occupy different subcarriers, i.e., different frequency offsets of REs of reference signals of different paging packets. As shown in fig. 3, 4 paging packets are configured. The 4 paging packets are represented with different padding, each occupying 4 REs in the RB. As shown in fig. 4, each paging packet occupies 8 REs in the RB, and 2 paging packets are configured up to this time. Based on fig. 3 and 4, it can be seen that the smaller the number of REs occupied by the reference signal, the larger the number of paging packets that can be configured. As shown in fig. 5, an interval of 1 RE is set between reference signals of different paging packets, and 2 paging packets are configured up to this time. Based on fig. 3 and 5, it can be seen that the smaller the size of the interval between REs occupied by the reference signal, the greater the number of paging packets that can be configured.

In addition, as can be seen from fig. 3 to fig. 5, each paging packet may correspond to a set of frequency domain offsets, which may be identified by subcarriers, and in fig. 3, for example, the frequency domain offset corresponding to one paging packet is

subcarrier

3, 7, and 11, respectively.

Illustratively, by default, there is only one paging packet, i.e., all subcarriers belong to one paging packet.

Optionally, the paging packet information includes a frequency domain offset of a reference signal of a paging packet in which the terminal is located; for example, the paging packet information includes subcarrier number: 3. 7, 11, and the

subcarriers

3, 7, 11 are frequency domain offsets of the reference signals of the paging packet. Alternatively, the paging packet information includes the sequence number of the RE.

Alternatively, the paging packet information includes an identification of a paging packet associated with a frequency domain offset of a reference signal of the paging packet. For example, the paging packet information includes an identification 00, and the frequency domain offset associated with the identification 00 is

subcarriers

3, 7, 11.

The access network device may configure the access network device with System Information in advance through a corresponding relationship between the identifier of the paging packet and the frequency domain offset of the reference signal of the paging packet, for example, through a System Information Block (SIB).

Optionally, the sending the paging packet information includes:

the sending the paging packet information includes:

and sending Downlink Control Information (DCI) carrying the paging packet Information to the terminal, where the paging packet Information includes a frequency domain offset of a reference signal used for PDSCH synchronization, or an identifier of a paging packet in the paging packet Information is associated with the frequency domain offset of the reference signal used for PDSCH synchronization.

The configuration information may be system information, Radio Resource Control (RRC) information, and the like.

The DCI is carried through a Physical Downlink Control Channel (PDCCH).

Fig. 6 is a schematic diagram of a reference signal transmission position provided by an embodiment of the present disclosure, referring to fig. 6, in a PO time, an access network device performs PDCCH transmission with a terminal first, and then performs PDSCH transmission.

If the paging packet information is transmitted using DCI carried by the PDCCH, the time domain location of the reference signal at this time is located between the PDCCH and the PDSCH, as shown in fig. 6. In this way, the reference signal can achieve fine synchronization of the PDSCH.

In this case, the access network device may, in addition to transmitting the paging packet information by using the DCI, indicate in the DCI whether to have a subsequent paging for the group of terminals, for example, indicate, by the identifier 00 of the paging packet, the paging packet in which the terminal is located in the DCI, and simultaneously indicate that the paging packet with the subsequent paging is 00, so that the terminal may not only determine whether to have the paging based on whether the reference signal is detected at the RE position of the reference signal, but also determine whether to have the paging based on the indication in the DCI, and may also combine the two manners to determine whether to have the paging, so that the paging detection accuracy of the terminal is higher.

When the paging packet information is transmitted using the configuration information, the time domain location of the reference signal may be located between the PDCCH and the PDSCH, as shown in fig. 6.

Fig. 7 and 8 are schematic diagrams of two other reference signal transmission positions provided by the embodiment of the present disclosure, referring to fig. 7 and 8, if the paging packet information is transmitted using the configuration information, the time domain position of the reference signal at this time may also be located before the PDCCH or after the PDSCH, as shown in fig. 7 and 8.

In the time domain, the PDCCH, the PDSCH and the reference signal may occupy one symbol, respectively.

It should be noted that, the foregoing steps 101 to 102 and the foregoing optional steps may be combined arbitrarily.

Fig. 9 is a flow chart illustrating a method of page detection in accordance with an example embodiment. Referring to fig. 9, the method includes the steps of:

in step 201, paging packet information is acquired.

The paging packet information is used to indicate a paging packet in which the terminal is located, and frequency domain offsets of reference signals of different paging packets are different, that is, in the embodiment of the present disclosure, the paging packet is implemented based on the frequency domain offset of the reference signal, for example, the frequency offsets of REs transmitting the reference signal are different for different paging packets.

In step 202, paging detection is performed based on the paging packet in which the terminal is located.

In the embodiment of the disclosure, the terminal may perform paging detection by first acquiring paging packet information and then based on the paging packet information. Because in the paging packet information, different paging packets are distinguished based on the frequency domain offset of the reference signal, compared with the CSI-RS sequence, more packets can be divided, so that the power consumption of the terminal in the paging detection process can be further reduced, and the power saving of the terminal is facilitated.

Optionally, the acquiring paging packet information includes:

the acquiring paging packet information includes:

In this implementation, the terminal receives the reference signal by shifting out of the frequency domain of the reference signal, and then determines whether there is a page for the paging packet in the PO. That is, if the reference signal is received, it is considered that there is a page for the paging packet, and if the reference signal is not received, it is considered that there is no page for the paging packet.

As shown in the foregoing, when the paging packet information is transmitted through the DCI carried by the PDCCH, the access network device may, in addition to transmitting the paging packet information by using the DCI, indicate in the DCI whether the paging of the group of terminals is available subsequently, for example, indicate, by using the identifier 00 of the paging packet, the paging packet in which the terminal is located in the DCI, and simultaneously indicate that the paging packet with the paging subsequently is 00, that is, the paging packet 00 has a paging message or a short message. At this time, the terminal may determine whether there is paging for the paging packet based on the indication in the DCI carried by the PDCCH.

In the embodiment of the present disclosure, when the time domain position of the reference signal is located between the PDCCH and the PDSCH, whether paging of the paging packet is available may also be determined by combining the two manners, that is, when the terminal receives the reference signal and the paging packet where the terminal is located has a paging message or a short message, it is determined that paging of the paging packet is available.

Optionally, the receiving and demodulating PDSCH includes:

In the embodiment of the present disclosure, a corresponding code domain resource may be configured for each paging packet, and the corresponding relationship may be sent to the terminal by the access network device through the configuration information.

In the embodiment of the present disclosure, because different paging packets are relatively close to each other in the frequency domain, in order to ensure transmission accuracy, different code domain resources may be configured for different paging packets, that is, different TRS/CSI-RS sequences corresponding to different paging packets are different.

It should be noted that, if the timing structure shown in fig. 7 is adopted, since the TRS/CSI-RS is located behind the PDSCH, at this time, the terminal may buffer the PDSCH first, and then determine whether to demodulate the PDSCH after receiving the TRS/CSI-RS.

It should be noted that, the foregoing steps 201 to 202 and the foregoing optional steps may be combined arbitrarily.

Fig. 10 is a flow chart illustrating a method of page detection in accordance with an example embodiment. Referring to fig. 10, the method includes the steps of:

in step 301, the access network device obtains paging packet information.

The paging packet information is used to indicate a paging packet in which the terminal is located, and frequency domain offsets of reference signals of different paging packets are different, that is, in the embodiment of the present disclosure, the paging packet is implemented based on the frequency domain offset of the reference signal, for example, different paging packets, R) for transmitting the reference signal are different in frequency offset.

In step 302, the access network device transmits the paging packet information. The terminal receives paging packet information.

In the embodiment of the present disclosure, the access network device and the terminal may transmit the paging packet information through the configuration information or the DCI.

In step 303, the terminal receives the reference signal according to the frequency domain offset of the reference signal of the paging packet where the terminal is located.

For example, the terminal receives the reference signal on the occupied sub-carriers (with positions in conjunction with the time domain) or occupied REs for reference signal transmission.

In step 304, the terminal receives and demodulates the PDSCH in response to the terminal receiving the reference signal.

This step may include: determining at least one code domain resource corresponding to a paging group where the terminal is located; and sequentially adopting code domain resources corresponding to the paging groups where the terminal is located to demodulate the PDSCH until the PDSCH is successfully demodulated.

For example, when the frequency difference of the two paging packets in the frequency domain does not exceed the threshold, the two paging packets may configure completely different code domain resources, that is, completely different TRS/CSI-RS sequences; when the frequency difference of the two paging packets in the frequency domain exceeds the threshold, the code domain resources configured for the two paging packets may be partially the same, that is, a part of the TRS/CSI-RS sequence may be multiplexed. As shown in fig. 3, for 4 paging packets, if the paging packets are divided into 4 groups from top to bottom, the frequency domain uplink frequency difference between the first group and the second group is small, the TRS/CSI-RS sequences between the two groups may be completely different, and the frequency domain uplink frequency difference between the first group and the fourth group is slightly large, the TRS/CSI-RS sequences between the two groups may be partially identical.

Illustratively, the threshold value here may be a frequency domain width of REs corresponding to 1 TRS/CSI-RS sequence. Generally, as shown in fig. 3 to 5, the frequency domain uplink frequency difference of each packet is small, and at least one TRS/CSI-RS sequence corresponding to different paging packets is different.

In step 305, the terminal determines whether the terminal has a paging message or a short message based on the information demodulated by the PDSCH.

For example, if the demodulated information from the PDSCH includes the identifier of the terminal, it indicates that there is a paging message or a short message for the terminal. If the demodulated information of the PDSCH does not contain the identification of the terminal, the fact that the paging message or the short message of the terminal does not exist is indicated.

Fig. 11 is a flow chart illustrating a method of page detection in accordance with an example embodiment. Referring to fig. 11, the method includes the steps of:

in step 401, the access network device obtains paging packet information.

The detailed procedure of this step is the same as step 301.

In step 402, the access network device transmits the paging packet information. The terminal receives paging packet information.

The detailed procedure of this step is the same as step 302.

In step 403, the terminal confirms whether a paging packet in which the terminal is located has a paging message or a short message based on the PDCCH.

In step 404, the terminal receives and demodulates the PDSCH in response to the paging packet in which the terminal is located having a paging message or a short message.

Wherein the step of decoding the PDSCH may refer to step 304.

In step 405, the terminal determines whether the terminal has a paging message or a short message based on the information demodulated by the PDSCH.

The detailed procedure of this step is the same as step 305.
