[0222] Among them, the base station 12 may be an evolved base station (eNB) adopted in the 4G system. Or, the base station 12 may also be a base station (gNB) with a centralized distributed architecture adopted in the 5G system. When the base station 12 adopts a centralized distributed architecture, it usually includes a central unit (CU) and at least two distributed units (DUs). The protocol stacks of the Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer are set in the central unit; the Physical (PHY) layer protocol stack is set in the distributed unit. The specific implementation manner of the base station 12 in the embodiments of the present disclosure is not limited.

[0223] A wireless connection may be established between the base station 12 and the terminal 11 through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as the new radio; or, the wireless air interface may also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0224] In some embodiments, an E2E (End to End) connection can also be established between terminals 11. For example, in scenarios such as V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communications in vehicle-to-everything (V2X) communications.

[0225] In some embodiments, the above wireless communication system may further include a network management device 13.

[0226] A plurality of base stations 12 are respectively connected to the network management device 13. Among them, the network management device 13 may be a core network device in the wireless communication system. For example, the network management device 13 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device may also be other core network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0227] The execution entities involved in the embodiments of the present disclosure include, but are not limited to: UEs such as mobile phone terminals supporting cellular mobile communications, and base stations, etc.

[0228] As Figure 2 shown, this exemplary embodiment provides a method for determining a paging message type. The method for determining a paging message type can be applied to a UE in a cellular mobile communication system, and includes:

[0229] Step 201: Detect the TRS / CSI-RS sent by the base station at the TRS / CSI-RS opportunity;

[0230] Step 202: Determine the type of the paging message based on the association information of the detected TRS / CSI-RS.

[0231] Here, the UE can be a mobile phone terminal or the like that performs wireless communication using cellular mobile communication technology. The base station can be a communication device that provides an access network interface to the UE in a cellular mobile communication system. The UE can be a UE in an idle state or an inactive state.

[0232] The TRS / CSI-RS can be a shared TRS / CSI-RS. The shared TRS / CSI-RS can be received by a UE in an idle state or an inactive state. The shared TRS / CSI-RS is used by the UE to obtain the channel state, beam management, mobility management, rate matching, etc. The idle-state UE and the inactive-state UE use the shared TRS / CRS to assist in network time-frequency domain synchronization.

[0233] The TRS / CSI-RS occasion can be configured by the base station. The UE can detect the TRS / CSI-RS at the TRS / CSI-RS occasion.

[0234] At the TRS / CSI-RS occasion, the base station can send the TRS / CSI-RS or not send the TRS / CSI-RS.

[0235] The base station can send different types of TRS / CSI-RS at the TRS / CSI-RS occasion.

[0236] The association information of the TRS / CSI-RS can include: the transmission state of the TRS / CSI-RS, and / or the type of the TRS / CSI-RS, etc.

[0237] The base station can indicate the type of the paging message to be sent by the TRS / CSI-RS at the TRS / CSI-RS occasion. The UE can detect the TRS / CSI-RS at the TRS / CSI-RS occasion and determine the type of the subsequent paging message based on the detected association information of the TRS / CSI-RS.

[0238] Here, the type of the paging message can be distinguished according to the signaling carrying the paging message. For example, the paging message can include a short message carried in the paging DCI and a paging message carried in the PDSCH signaling. The type of the paging message can be distinguished according to the service type of the content carried by the paging message. The type of the paging message can also be distinguished according to the priority level of the content carried by the paging message, etc.

[0239] In this way, the base station indicates the type of the paging message by sending the TRS / CSI-RS, providing a new method for indicating the type of the paging message, which improves the flexibility of indicating the type of the paging message.

[0240] In one embodiment, determining the type of the paging message based on the detected association information of the TRS / CSI-RS includes:

[0241] Determine the type of the paging message based on the detected transmission status of the TRS / CSI-RS.

[0242] Here, the transmission status of the TRS / CSI-RS includes whether the TRS / CSI-RS is detected in the TRS / CSI-RS occasion.

[0243] The base station can indicate the type of the paging message to be sent by the base station to the UE by whether to send the TRS / CSI-RS in the TRS / CSI-RS occasion.

[0244] The UE can determine the type of the paging message to be sent by the base station by whether the TRS / CSI-RS is detected in the TRS / CSI-RS occasion.

[0245] In a possible implementation, the determining the type of the paging message based on the detected transmission status of the TRS / CSI-RS includes:

[0246] In response to detecting the TRS / CSI-RS in the TRS / CSI-RS occasion, determine that the paging message is a first type of paging message.

[0247] In another possible implementation, the determining the type of the paging message based on the detected transmission status of the TRS / CSI-RS includes:

[0248] In response to not detecting the TRS / CSI-RS in the TRS / CSI-RS occasion, determine that the paging message is a second type of paging message; wherein, the first type of paging message is different from the second type of paging message.

[0249] Wherein, these two possible implementation manners described above can be used together or separately, and the embodiments of the present disclosure do not make any limitations thereto.

[0250] Here, the first type of paging message being different from the second type of paging message may include: the data amounts included in the first type of paging message and the second type of paging message are different, the signaling included in the first type of paging message and the second type of paging message is different, the services carried by the first type of paging message and the second type of paging message are different, and / or the priorities of the services carried by the first type of paging message and the second type of paging message are different, etc.

[0251] In one embodiment, the first type of paging message includes: a paging message transmitted using a downlink shared physical channel PDSCH, and the second type of paging message at least includes: a short message.

[0252] The main function of the first type of paging message is to notify the UE in the idle state and / or inactive state of a connection request, and to notify the UE in the idle state, inactive state, and / or connected state that the system message has changed. The first type of paging message is transmitted using PDSCH resources, and the UE can obtain the scheduling information of the paging message by listening to the PDCCH. When the UE detects the scheduling information of paging scheduling on the PDCCH, it receives the first type of paging message on the PDSCH resource according to the scheduling information.

[0253] The second type of paging message can be a short message carried in the paging DCI. The short message can occupy 8 bits and can be used to indicate the change of communication system information and to indicate the stop of paging message monitoring, etc.

[0254] For different types of paging messages, the UE can adopt different synchronization methods. For example, for paging messages transmitted using PDSCH resources, multiple SSBs can be used for synchronization and receiving paging messages. For short messages, 1 SSB can be used for synchronization and receiving paging messages.

[0255] In a possible implementation, the method further includes:

[0256] In response to determining that the paging message is the first type of paging message, receive the first type of paging message based on the synchronization completed through the TRS / CSI-RS.

[0257] If the TRS / CSI-RS is detected at the TRS / CSI-RS timing, the UE can perform downlink synchronization through the TRS / CSI-RS. The UE can receive the first type of paging message based on the downlink synchronization completed through the TRS / CSI-RS.

[0258] Exemplarily, as Figure 3 described, the first type of paging message can be a paging message transmitted using PDSCH; if the UE detects the TRS / CSI-RS at the TRS / CSI-RS timing, the UE directly uses the TRS / CRS for synchronization and continues to monitor the subsequent PO and PDSCH based on the completed synchronization.

[0259] In this way, the UE no longer needs to perform downlink synchronization using the SSB. Since the time required for downlink synchronization using the SSB is relatively long, performing downlink synchronization using the TRS / CSI-RS and receiving the first type of paging message can reduce the power consumption increase caused by the relatively long wake-up time of the UE.

[0260] In another possible implementation, the method further includes:

[0261] In response to determining that the paging message is a second type of paging message, receive the second type of paging message based on synchronization completed through a predetermined number of SSBs.

[0262] If TRS / CSI-RS is not detected in the TRS / CSI-RS occasion, the UE can perform downlink synchronization through the SSB. The UE can receive the first type of paging message based on the downlink synchronization completed through the SSB.

[0263] Exemplarily, as Figure 4 described, the second type of paging message can be a short message; if the UE does not detect TRS / CSI-RS in the TRS / CSI-RS occasion, the UE can use the SSB for synchronization and monitor the PO based on the downlink synchronization completed through the SSB. Since a single SSB can be used for synchronization when monitoring the PO, the power consumption increase caused by the longer wake-up time due to the UE using multiple SSBs for synchronization can be reduced.

[0264] Among them, the above two possible implementation manners can be used together or separately, and the embodiments of the present disclosure do not limit this.

[0265] In one embodiment, the method further includes:

[0266] Receive first indication information;

[0267] The detecting, in the TRS / CSI-RS occasion, the TRS / CSI-RS sent by the base station includes:

[0268] In response to the first indication information indicating that the TRS / CSI-RS is in an available state, detect the TRS / CSI-RS in the TRS / CSI-RS occasion.

[0269] Before the base station implicitly expresses the type of the paging message through the actual transmission state of the TRS / CRS, the base station can notify the availability of the TRS / CRS in advance. The base station can send first indication information indicating that the availability of the TRS / CRS is available.

[0270] The available state of the TRS / CRS means that the network notifies that the configuration of the TRS / CRS for the terminal is reasonably existent, and is indicated by the associated information of the TRS / CRS based on the pre-configured TRS / CRS position when implicitly expressing the type of the paging message.

[0271] In one embodiment, the receiving the first indication information includes at least one of the following:

[0272] Receive a broadcast message carrying the first indication information;

[0273] Receive an RRC message carrying the first indication information;

[0274] Receive a DCI carrying the first indication information.

[0275] The base station notifies that the TRS / CRS is in an available state through broadcast messages, RRC messages, DCIs, etc. The first indication information can use two values of 1 bit to respectively indicate that the available state of the TRS / CRS is available or unavailable. The first indication information can occupy reserved bits of broadcast messages, RRC messages, and / or DCIs, etc.

[0276] In one embodiment, the method further includes:

[0277] Receive second indication information;

[0278] Determine that the base station has the paging message in the downlink according to the second indication information.

[0279] Before the TRS / CRS timing, the base station can pre-indicate to the UE by sending the second indication information that there will be a paging coming. The base station may not inform the specific type of paging information.

[0280] After receiving the second indication information, the UE can determine that the paging information is about to come.

[0281] In one embodiment, the receiving the second indication information includes at least one of the following:

[0282] Receive the PSS or the disabled PSS, where the time domain position of the PSS is before the time domain position of the TRS / CSI-RS timing;

[0283] Receive the PEI or the disabled PEI, where the time domain position of the PEI is before the time domain position of the TRS / CSI-RS timing.

[0284] Here, the base station can use the PSS to indicate that the base station has paging information in the downlink. The PSS can use two values to respectively indicate that the base station has paging information in the downlink and the base station does not have paging information in the downlink. The UE can determine whether there is paging information in the downlink based on the indication of the PSS.

[0285] The base station can use the PEI to indicate that the base station has paging information in the downlink. The PEI can use two values to respectively indicate that the base station has paging information in the downlink and the base station does not have paging information in the downlink. The UE can determine whether there is paging information in the downlink based on the indication of the PEI.

[0286] Here, the base station may use a disabled PSS and / or a disabled PEI to indicate that the base station has paging information in the downlink. When the UE receives a disabled PSS and / or a disabled PEI, it may determine that the base station has paging information in the downlink.

[0287] In one embodiment, the detecting of the TRS / CSI-RS sent by the base station at the TRS / CSI-RS occasion includes:

[0288] In response to receiving first indication information indicating that the TRS / CSI-RS is in an available state, and second indication information indicating that the base station has the paging message in the downlink, perform a blind detection at the TRS / CSI-RS occasion.

[0289] When the UE receives the first indication information and the second indication information sent by the base station, it may determine that the UE determines the type of the paging message based on the associated information of the detected TRS / CSI-RS. The UE may perform a blind detection at the TRS / CSI-RS occasion to determine whether the base station sends the TRS / CSI-RS at the TRS / CSI-RS occasion.

[0290] Exemplarily, based on the available state of the TRS / CRS being available and the arrival of the paging message, the UE performs a blind detection at the TRS / CRS position and determines the type of the paging message according to the result of the blind detection.

[0291] When the base station sends the first indication information and the second indication information, it may implicitly indicate that the TRS / CSI-RS may not be sent at the TRS / CSI-RS occasion. Therefore, the UE needs to perform a blind detection at the TRS / CSI-RS occasion.

[0292] In one embodiment, the performing of the blind detection at the TRS / CSI-RS occasion includes at least one of the following:

[0293] Perform a blind detection at the TRS / CSI-RS occasion based on a blind detection indication sent by the base station;

[0294] Perform a blind detection at the TRS / CSI-RS occasion based on the provisions of the communication protocol.

[0295] The base station may send a blind detection indication to the UE, indicating that the UE performs a blind detection at the TRS / CSI-RS occasion. The base station may notify the UE in advance to perform a blind detection before the TRS / CSI-RS occasion. After receiving the blind detection indication, the UE performs a blind detection at the TRS / CSI-RS occasion. Whether to perform a blind detection may be specified by the communication protocol. For example, when the base station sends the first indication information and the second indication information, the communication protocol may specify that the UE needs to perform a blind detection. When the base station uses the type of the TRS / CSI-RS to indicate the type of the paging message, the communication protocol may specify that the UE does not need to perform a blind detection.

[0296] In one embodiment, determining the type of the paging message based on the detected association information of the TRS / CSI-RS includes:

[0297] Determining the type of the paging message based on the detected type of the TRS / CSI-RS.

[0298] Here, the base station can send different types of TRS / CSI-RS at the TRS / CSI-RS occasion for different types of paging information. Different types of paging information can respectively correspond to different types of TRS / CSI-RS.

[0299] The type of the TRS / CSI-RS can be divided based on transmission resources, or can be divided based on the signal sequence of the TRS / CSI-RS, etc.

[0300] The base station can indicate the type of the paging message to be sent by the base station to the UE by sending different types of TRS / CSI-RS at the TRS / CSI-RS occasion.

[0301] The UE can determine the type of the paging message to be sent by the base station based on the type of the TRS / CSI-RS detected at the TRS / CSI-RS occasion.

[0302] In one embodiment, the time domain resources of different types of the TRS / CSI-RS are different;

[0303] and / or

[0304] The frequency domain resources of different types of the TRS / CSI-RS are different;

[0305] and / or

[0306] The sequences of different types of the TRS / CSI-RS are different;

[0307] and / or

[0308] The time domain offsets of different types of the TRS / CSI-RS are different.

[0309] Different types of the TRS / CSI-RS can be sent using different time domain resources, and the UE can determine the type of the TRS / CSI-RS based on the time domain resources for receiving the TRS / CSI-RS.

[0310] Different types of the TRS / CSI-RS can be sent using different frequency domain resources, and the UE can determine the type of the TRS / CSI-RS based on the frequency domain resources for receiving the TRS / CSI-RS.

[0311] The different types of the TRS / CSI-RS may adopt different signal sequences or scrambling sequences, etc., and the UE may determine different types of the TRS / CSI-RS based on the sequences of the TRS / CSI-RS.

[0312] The different types of the TRS / CSI-RS may be offset based on the same time domain reference, and the UE may determine the type of the TRS / CSI-RS based on the time domain offset of the TRS / CSI-RS.

[0313] In a possible implementation manner, determining the type of the paging message based on the detected type of the TRS / CSI-RS includes:

[0314] In response to detecting a first type of the TRS / CSI-RS at the TRS / CSI-RS occasion, determining that the paging message is a first type of paging message.

[0315] In another possible implementation manner, determining the type of the paging message based on the detected type of the TRS / CSI-RS includes:

[0316] In response to detecting a second type of the TRS / CSI-RS at the TRS / CSI-RS occasion, determining that the paging message is a second type of paging message; wherein, the first type of the TRS / CSI-RS is different from the second type of the TRS / CSI-RS, and the first type of the paging message is different from the second type of the paging message.

[0317] The corresponding relationship between the type of the TRS / CSI-RS and the type of the paging message may be preset. After receiving the TRS / CSI-RS, the UE may determine the type of the paging message according to the corresponding relationship.

[0318] Among them, the above two possible implementation manners may be used together or separately, and the embodiments of the present disclosure do not make any limitation thereto.

[0319] Here, the first type of the paging message being different from the second type of the paging message may include: the data amounts included in the first type of the paging message and the second type of the paging message are different, the signaling included in the first type of the paging message and the second type of the paging message is different, the services carried by the first type of the paging message and the second type of the paging message are different, and / or the priorities of the services carried by the first type of the paging message and the second type of the paging message are different, etc.

[0320] In one embodiment, the method further includes:

[0321] Receiving third indication information;

[0322] Determine that the base station transmits the TRS / CSI-RS at the TRS / CSI-RS occasion according to the third indication information;

[0323] The detecting, at the TRS / CSI-RS occasion, of the TRS / CSI-RS transmitted by the base station includes:

[0324] In response to receiving the third indication information, detect the type of the TRS / CSI-RS transmitted by the base station at the TRS / CSI-RS occasion.

[0325] Before the base station indicates the type of the paging message through the type of the TRS / CRS, the base station may notify the UE in advance, by using the third indication information, that the base station will transmit the TRS / CRS at the TRS / CSI-RS occasion, and indicate the type of the paging message by using the type of the TRS / CRS. The third indication information may indicate that the TRS / CRS is available, that is, indicate that there must be a TRS / CRS at the TRS / CRS occasion. Blind detection may no longer be performed, but instead the type of the TRS / CRS may be directly detected.

[0326] In one embodiment, since it is determined that there is a TRS / CRS at the TRS / CRS occasion, the third indication information may implicitly indicate that the UE does not need to blindly detect the TRS / CRS.

[0327] The network may transmit multiple sets of TRS / CRS at the TRS / CRS occasion, and the terminal determines the specific type of the paging message based on the result of the TRS / CRS detection.

[0328] Whether to perform blind detection may be specified by a communication protocol. For example, when the base station sends the first indication information and the second indication information, the communication protocol may specify that the UE needs to perform blind detection. When the base station uses the third indication information to indicate the type of the paging message through the type of the TRS / CSI-RS, the communication protocol may specify that the UE does not need to perform blind detection and directly detect.

[0329] In one embodiment, the receiving of the third indication information includes at least one of the following:

[0330] Receive a broadcast message carrying the third indication information;

[0331] Receive an RRC message carrying the third indication information;

[0332] Receive a DCI carrying the third indication information.

[0333] The base station may carry third indication information in messages such as broadcast messages, RRC messages, and DCI. The third indication information may use two values of 1 bit to respectively indicate that the available state of TRS / CRS is available or unavailable. When the third indication information indicates that the available state of TRS / CRS is available, the UE may occupy reserved bits such as those in broadcast messages, RRC messages, and / or DCI according to detections. In this way, the information carrying capacity of broadcast messages, RRC messages, and / or DCI can be improved, and the information transmission efficiency can be increased.

[0334] In one embodiment, the TRS / CSI-RS timing position is not earlier than the paging occasion of the paging message in the time domain.

[0335] The TRS / CSI-RS timing position is not earlier than the paging occasion of the paging message in the time domain. The UE may receive the paging message after the TRS / CSI-RS timing is determined. In this way, the UE may determine the type of the paging message before receiving the paging message, and then determine the manner of receiving the paging message and performing synchronization, etc.

[0336] In one embodiment, the TRS / CSI-RS timing position overlaps with the paging occasion in the time domain;

[0337] There is a predetermined number of SSB periods between the TRS / CSI-RS timing and the paging occasion.

[0338] The network may pre-configure the TRS / CRS timing as an offset before the PO; or the TRS / CRS timing may overlap with the PO; in this way, the UE may complete downlink synchronization for receiving the paging message before the paging message.

[0339] After the UE determines the type of the paging message at the TRS / CRS timing, it may perform downlink synchronization based on the TRS / CRS, or perform synchronization based on the SSB.

[0340] As Figure 5 shown, this exemplary embodiment provides a method for determining the type of a paging message. The method for determining the type of a paging message may be applied to a base station in a cellular mobile communication system, and includes:

[0341] Step 501: Indicate the type of the paging message through the TRS / CSI-RS at the TRS / CSI-RS timing.

[0342] Here, the UE may be a mobile phone terminal or the like that performs wireless communication using cellular mobile communication technology. The base station may be a communication device that provides an access network interface to the UE in a cellular mobile communication system. The UE may be a UE in an idle state or a non-active state.

[0343] The TRS / CSI-RS can be a shared TRS / CSI-RS. The shared TRS / CSI-RS can be received by UEs in the idle state or the inactive state. The shared TRS / CSI-RS is used by UEs to obtain channel state, beam management, mobility management, rate matching, etc. The idle-state UEs and inactive-state UEs use the shared TRS / CRS to assist in network time-frequency domain synchronization.

[0344] The TRS / CSI-RS occasion can be configured by the base station. The UE can detect the TRS / CSI-RS at the TRS / CSI-RS occasion.

[0345] At the TRS / CSI-RS occasion, the base station can send the TRS / CSI-RS or not send the TRS / CSI-RS.

[0346] The base station can send different types of TRS / CSI-RS at the TRS / CSI-RS occasion.

[0347] The associated information of the TRS / CSI-RS can include: the transmission state of the TRS / CSI-RS, and / or the type of the TRS / CSI-RS, etc.

[0348] The base station can indicate the type of the paging message to be sent by the TRS / CSI-RS at the TRS / CSI-RS occasion. The UE can detect the TRS / CSI-RS at the TRS / CSI-RS occasion and determine the type of the subsequent paging message based on the associated information of the detected TRS / CSI-RS.

[0349] Here, the type of the paging message can be distinguished according to the signaling carrying the paging message. For example, the paging message can include a short message carried in the paging DCI and a paging message carried in the PDSCH signaling. The type of the paging message can be distinguished according to the service type of the content carried by the paging message. The type of the paging message can also be distinguished according to the priority level of the content carried by the paging message, etc.

[0350] In this way, the base station indicates the type of the paging message by sending the TRS / CSI-RS, providing a new method for indicating the type of the paging message, which improves the flexibility of indicating the type of the paging message.

[0351] In one embodiment, the TRS / CSI-RS at the TRS / CSI-RS occasion includes:

[0352] Indicating the type of the paging message by whether to send the TRS / CSI-RS at the TRS / CSI-RS occasion.

[0353] Here, the transmission status of the TRS / CSI-RS includes: whether the TRS / CSI-RS is detected at the TRS / CSI-RS occasion.

[0354] The base station can indicate the type of paging message to be sent by the base station to the UE by whether to send the TRS / CSI-RS at the TRS / CSI-RS occasion.

[0355] The UE can determine the type of paging message to be sent by the base station by whether the TRS / CSI-RS is detected at the TRS / CSI-RS occasion.

[0356] In a possible implementation, the indication of the type of the paging message by whether to send the TRS / CSI-RS at the TRS / CSI-RS occasion includes:

[0357] In response to sending the TRS / CSI-RS at the TRS / CSI-RS occasion, it is indicated that the paging message is a first type of paging message.

[0358] In another possible implementation, the indication of the type of the paging message by whether to send the TRS / CSI-RS at the TRS / CSI-RS occasion includes:

[0359] In response to not sending the TRS / CSI-RS at the TRS / CSI-RS occasion, it is indicated that the paging message is a second type of paging message; wherein, the first type of paging message is different from the second type of paging message.

[0360] Wherein, these two possible implementations above can be used together or separately, and the embodiments of the present disclosure do not make any limitations thereto.

[0361] Here, the first type of paging message being different from the second type of paging message may include: the data volumes included in the first type of paging message and the second type of paging message are different, the signaling included in the first type of paging message and the second type of paging message is different, the services carried by the first type of paging message and the second type of paging message are different, and / or the priorities of the services carried by the first type of paging message and the second type of paging message are different, etc.

[0362] In one embodiment, the first type of paging message includes: a paging message transmitted using the downlink shared physical channel PDSCH, and the second type of paging message at least includes: a short message.

[0363] The main function of the first type of paging message is to notify the UE in the idle state and / or inactive state of a connection request, and to notify the UE in the idle state, inactive state, and / or connected state that the system message has changed. The first type of paging message is transmitted using PDSCH resources, and the UE can obtain the scheduling information of the paging message by listening to the PDCCH. When the UE listens to the scheduling information of paging scheduling on the PDCCH, it receives the first type of paging message on the PDSCH resource according to this scheduling information.

[0364] The second type of paging message can be a short message carried in the paging DCI. The short message can occupy 8 bits and can be used to indicate the change of communication system information and to indicate the stop of paging message listening, etc.

[0365] For different types of paging messages, the UE can adopt different synchronization methods. For example, for the paging message transmitted using PDSCH resources, multiple SSBs can be used for synchronization and receiving the paging message. For the short message, 1 SSB can be used for synchronization and receiving the paging message.

[0366] In one embodiment, the method further includes:

[0367] Sending first indication information, where the first indication information is used to indicate that the TRS / CSI-RS is in an available state and to indicate that the user equipment UE detects the TRS / CSI-RS at the TRS / CSI-RS opportunity.

[0368] Before the base station implicitly expresses the type of paging message through the actual transmission state of the TRS / CRS, the base station can notify the availability of the TRS / CRS in advance. The base station can send first indication information to indicate that the availability of the TRS / CRS is available.

[0369] The available state of the TRS / CRS means that the network notifies that the configuration of the TRS / CRS for the terminal is reasonably existent, and it is indicated by the associated information of the TRS / CRS based on the pre-configured TRS / CRS position when implicitly expressing the type of paging message.

[0370] In one embodiment, the sending of the first indication information includes at least one of the following:

[0371] Sending a broadcast message carrying the first indication information;

[0372] Sending an RRC message carrying the first indication information;

[0373] Sending a DCI carrying the first indication information.

[0374] The base station notifies that the TRS / CRS is in an available state, which can be through broadcast messages, RRC messages, DCI, etc. The first indication information can use two values of 1 bit to respectively indicate that the available state of the TRS / CRS is available or unavailable. The first indication information can occupy reserved bits of broadcast messages, RRC messages, and / or DCI, etc.

[0375] In one embodiment, the method further includes:

[0376] Sending second indication information, where the second indication information is used to indicate that the base station has the paging message in the downlink.

[0377] Before the TRS / CRS occasion, the base station can pre-indicate to the UE by sending the second indication information that there will be a paging coming. The base station may not inform the specific type of paging information.

[0378] After receiving the second indication information, the UE can determine that the paging information is about to come.

[0379] In one embodiment, the sending of the second indication information includes at least one of the following:

[0380] Sending the PSS or the disabled PSS, where the time domain position of the PSS is before the time domain position of the TRS / CSI-RS occasion;

[0381] Sending the PEI or the disabled PEI, where the time domain position of the PEI is before the time domain position of the TRS / CSI-RS occasion.

[0382] Here, the base station can use the PSS to indicate that the base station has the paging information in the downlink. The PSS can use two values to respectively indicate that the base station has the paging information in the downlink and that the base station does not have the paging information in the downlink. The UE can determine whether it has the paging information in the downlink based on the indication of the PSS.

[0383] The base station can use the PEI to indicate that the base station has the paging information in the downlink. The PEI can use two values to respectively indicate that the base station has the paging information in the downlink and that the base station does not have the paging information in the downlink. The UE can determine whether it has the paging information in the downlink based on the indication of the PEI.

[0384] Here, the base station can use the disabled PSS and / or the disabled PEI to indicate that the base station has the paging information in the downlink. When the UE receives the disabled PSS and / or the disabled PEI, it can determine that the base station has the paging information in the downlink.

[0385] In one embodiment, the method further includes:

[0386] Send a blind detection indication, which is used to instruct the UE to perform blind detection at the TRS / CSI-RS occasion.

[0387] The base station can send a blind detection indication to the UE, instructing the UE to perform blind detection at the TRS / CSI-RS occasion. The base station can notify the UE in advance to perform blind detection before the TRS / CSI-RS occasion. After receiving the blind detection indication, the UE performs blind detection at the TRS / CSI-RS occasion.

[0388] In one embodiment, the type of the paging message is indicated by the TRS / CSI-RS at the TRS / CSI-RS occasion, including:

[0389] By sending different types of the TRS / CSI-RS, different types of the paging messages are indicated.

[0390] Here, the base station can send different types of TRS / CSI-RS at the TRS / CSI-RS occasion for different types of paging information. Different types of paging information can respectively correspond to different types of TRS / CSI-RS.

[0391] The type of the TRS / CSI-RS can be divided based on transmission resources, or can be divided based on the signal sequence of the TRS / CSI-RS, etc.

[0392] The base station can indicate the type of the paging message to be sent to the UE by sending different types of TRS / CSI-RS at the TRS / CSI-RS occasion.

[0393] The UE can determine the type of the paging message to be sent by the base station based on the type of the TRS / CSI-RS detected at the TRS / CSI-RS occasion.

[0394] In one embodiment, the time-domain resources of different types of the TRS / CSI-RS are different;

[0395] and / or

[0396] The frequency-domain resources of different types of the TRS / CSI-RS are different;

[0397] and / or

[0398] The sequences of different types of the TRS / CSI-RS are different;

[0399] and / or

[0400] The time-domain offsets of different types of the TRS / CSI-RS are different.

[0401] Different types of the TRS / CSI-RS may be transmitted using different time-domain resources, and the UE may determine the type of the TRS / CSI-RS based on the time-domain resources for receiving the TRS / CSI-RS.

[0402] Different types of the TRS / CSI-RS may be transmitted using different frequency-domain resources, and the UE may determine the type of the TRS / CSI-RS based on the frequency-domain resources for receiving the TRS / CSI-RS.

[0403] Different types of the TRS / CSI-RS may use different signal sequences or scrambling sequences, etc., and the UE may determine different types of the TRS / CSI-RS based on the sequences of the TRS / CSI-RS.

[0404] Different types of the TRS / CSI-RS may be offset based on the same time-domain reference, and the UE may determine the type of the TRS / CSI-RS based on the time-domain offset of the TRS / CSI-RS.

[0405] In one possible implementation, the indication of different types of the paging messages by transmitting different types of the TRS / CSI-RS includes:

[0406] In response to transmitting a first type of TRS / CSI-RS at the TRS / CSI-RS occasion, indicating that the paging message is a first type of paging message.

[0407] In another possible implementation, the indication of different types of the paging messages by transmitting different types of the TRS / CSI-RS includes:

[0408] In response to transmitting a second type of TRS / CSI-RS at the TRS / CSI-RS occasion, indicating that the paging message is a second type of paging message; wherein, the first type of TRS / CSI-RS is different from the second type of TRS / CSI-RS, and the first type of paging message is different from the second type of paging message.

[0409] The corresponding relationship between the type of the TRS / CSI-RS and the type of the paging message may be preset. After receiving the TRS / CSI-RS, the UE may determine the type of the paging message according to the corresponding relationship.

[0410] Among them, these two possible implementations above may be used together or separately, and the embodiments of the present disclosure do not limit this.

[0411] Here, the difference between the first type of paging message and the second type of paging message may include: the data volumes contained in the first type of paging message and the second type of paging message are different, the signaling contained in the first type of paging message and the second type of paging message is different, the services carried by the first type of paging message and the second type of paging message are different, and / or the priorities of the services carried by the first type of paging message and the second type of paging message are different, etc.

[0412] In one embodiment, the method further includes: sending third indication information, where the third indication information is used to indicate that the base station sends the TRS / CSI-RS at the TRS / CSI-RS opportunity.

[0413] Before the base station indicates the type of the paging message through the type of the TRS / CRS, the base station may notify the UE in advance by using the third indication information to use the type of the TRS / CRS to indicate the type of the paging message. The third indication information may indicate that the TRS / CRS is available, that is, it indicates that there must be a TRS / CRS at the TRS / CRS opportunity. Blind detection may no longer be performed, but the type of the TRS / CRS may be directly detected.

[0414] In one embodiment, since there is a TRS / CRS when determining the TRS / CRS opportunity, the third indication information may implicitly indicate that the UE does not need to blindly detect the TRS / CRS.

[0415] The network may send multiple sets of TRS / CRS at the TRS / CRS opportunity, and the terminal determines the specific type of the paging message based on the result of the TRS / CRS detection.

[0416] Whether to perform blind detection may be specified by the communication protocol. For example, when the base station sends the first indication information and the second indication information, the communication protocol may specify that the UE needs to perform blind detection. When the base station uses the third indication information to indicate the type of the paging message through the type of the TRS / CSI-RS, the communication protocol may specify that the UE does not need to perform blind detection and directly perform detection.

[0417] In one embodiment, the sending of the third indication information includes at least one of the following:

[0418] Sending a broadcast message carrying the third indication information;

[0419] Sending an RRC message carrying the third indication information;

[0420] Sending a DCI carrying the third indication information.

[0421] The base station may carry third indication information in messages such as broadcast messages, RRC messages, and DCI. The third indication information may use two values of 1 bit to respectively indicate that the available status of TRS / CRS is available or unavailable. When the third indication information indicates that the available status of TRS / CRS is available, the UE may occupy the reserved bits of the broadcast message, RRC message, and / or DCI according to the detection. In this way, the information carrying capacity of the broadcast message, RRC message, and / or DCI can be improved, and the information transmission efficiency can be mentioned.

[0422] In one embodiment, the TRS / CSI-RS timing position is not earlier than the paging occasion of the paging message in the time domain.

[0423] The TRS / CSI-RS timing position is not earlier than the paging occasion of the paging message in the time domain. After the TRS / CSI-RS timing is determined, the UE may receive the paging message. In this way, the UE may determine the type of the paging message before receiving the paging message, and then determine the manner of receiving the paging message and performing synchronization, etc.

[0424] In one embodiment, the TRS / CSI-RS timing position overlaps with the paging occasion in the time domain;

[0425] There is a predetermined number of SSB periods between the TRS / CSI-RS timing and the paging occasion.

[0426] The network may pre-configure the TRS / CRS timing as an offset before the PO; or the TRS / CRS timing may overlap with the PO; in this way, the UE may complete downlink synchronization for receiving the paging message before the paging message.

[0427] After the UE determines the type of the paging message at the TRS / CRS timing, it may perform downlink synchronization based on the TRS / CRS, or synchronize based on the SSB.

[0428] The following provides a specific example in combination with any of the above embodiments:

[0429] 1. The network side implicitly expresses the type of the paging message through the actual transmission status of the TRS / CRS.

[0430] a) The actual transmission status of the TRS / CRS is whether the network actually sends the corresponding TRS / CRS at the pre-configured TRS / CRS timing.

[0431] b) Whether the call type is a short message or a paging message transmitted using PDSCH resources.

[0432] 2. Before the network implicitly expresses the type of call through the actual transmission status of TRS / CRS, the network has previously notified that the availability of TRS / CRS is available.

[0433] a) As an embodiment, the available status of TRS / CRS means that the network notifies that the configuration of TRS / CRS for the terminal is reasonably existent, and the corresponding TRS / CRS will be sent at the pre-configured TRS / CRS timing when implicitly expressing the type of call.

[0434] b) The network has previously notified that the availability of TRS / CRS can be through broadcast messages, RRC messages, DCI, etc.

[0435] 3. Before the network implicitly expresses the type of call through the actual transmission status of TRS / CRS, the network has previously notified that paging will come, but does not inform the specific type of paging.

[0436] 4. The network notifies the user that there is a paging for this PO by pre-sending a power saving signal PSS or PEI.

[0437] As an embodiment, the network pre-sends PSS or PEI before sending the corresponding TRS / CRS at the pre-configured TRS / CRS timing.

[0438] 5. The network can notify the user that there is a paging for this PO by disabling PSS or PEI; that is, the network side notifies the terminal that there must be a paging for this PO.

[0439] 6. The terminal performs blind detection at the TRS / CRS timing based on the availability of TRS / CRS being available and the arrival of the paging message, and determines the specific type of the paging message according to the result of the blind detection.

[0440] a) As an embodiment, the pre-configured TRS / CRS timing by the network is before the first N SSBs of the PO; for example, 3 SSBs.

[0441] b) As an embodiment, the network can pre-notify the terminal that it needs to perform blind detection on TRS / CRS or by pre-agreement in the protocol.

[0442] 7. If the UE detects TRS / CRS, it means that the specific type of the current paging message is the first type of paging message, such as a paging message for paging the terminal. At this time, the terminal synchronizes using TRS / CRS and continues to monitor the subsequent PagingDCI and subsequent PDSCH.

[0443] 8. If the UE does not detect the TRS / CRS, it means that the specific type of the current paging message is the second type of paging message, such as just a short message. In this case, the original SSB can be used to synchronize and detect the paging DCI.

[0444] a) As an embodiment, the number of SSB synchronizations can be carried out in accordance with the protocol agreement or determined by the terminal implementation, such as 1 SSB.

[0445] 9. The terminal detects at the TRS / CRS timing based on the availability of the TRS / CRS being available and the arrival of the paging message, and determines the specific type of the paging message according to the detection result.

[0446] a) As an embodiment, the TRS / CRS timing pre-configured by the network is an offset before the PO; or it can overlap with the PO.

[0447] b) As an embodiment, the network can notify the terminal in advance or pre-agree in the protocol that the terminal does not need to blindly detect the TRS / CRS; (in this case, the terminal will surely detect the transmission of the TRS / CRS).

[0448] c) As an embodiment, when the network notifies the availability of the TRS / CRS in 2), it implies that there must be a TRS / CRS transmission at the pre-configured TRS / CRS timing; in this case, the terminal will surely detect the transmission of the TRS / CRS.

[0449] 10. The network sends multiple sets of TRS / CRS at the pre-configured TRS / CRS timing, and the terminal determines the specific type of the paging message based on the detection result of the TRS / CRS.

[0450] a) As an embodiment, at this time, different TRS / CRS resources can be distinguished by time-frequency resources, sequence generation, and offset; to distinguish the specific types of different paging messages.

[0451] The following is an embodiment. The terminal blindly detects the TRS / CRS timing and determines the type of the paging message according to whether the TRS / CRS is detected.

[0452] As Figure 6 shown, in the related art, in the case of no TRS / CRS, the terminal needs 3 SSBs for synchronization, so the terminal always needs 3 SSBs to pass.

[0453] Using the method of the embodiment of the present disclosure, as Figure 3As shown, it is realized by blind detection of TRS / CRS. That is, if TRS / CRS is detected, directly synchronize using TRS / CRS and continue to monitor subsequent PO and PDSCH; as Figure 4 shown, if TRS / CRS is not detected, fewer SSBs can be used and only subsequent POs are monitored.
