The wireless communication system may be a fourth generation mobile communication (4G) system, which is also called a Long Term Evolution (LTE) system; alternatively, the wireless communication system can be a 5G system, which is also called a New Radio (NR) system or a 5G NR system.

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), a Home Subscriber Server (HSS), or the like. The implementation form of the network management device 13 is not limited in the embodiment of the present disclosure.

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, at present, the paging message may be divided into a core network paging message (CN paging) and an access network paging message (RAN paging) according to a source of the paging message. For idle UEs, only CN paging is received. For the inactive UE, if the context information retained by the base station is normal, the RAN paging is received, and if the context information is abnormal, the CN paging is received.

In the related technology, the CRC of the DCI carrying the paging scheduling information corresponding to the CN paging and/or the RAN paging is scrambled by adopting P-RNTI, and different scrambling modes are not adopted for the UE in different RRC connection states. Therefore, regardless of the type of paging message scheduled by the DCI, the UE may descramble and decode the DCI in whatever state. For example, the UE in the connected state also descrambles DCI scheduled by the CN paging, and a receiving object of the CN paging is not the UE in the connected state, so that system resources of the UE are consumed, and power consumption of the UE is increased.

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

step 201: and responding to the DCI scheduling paging messages of the same type, and scrambling the CRC of the DCI by adopting a scrambling identifier associated with the RRC connection state paging message of the UE associated with the paging messages.

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 communication network may send paging messages to UEs in idle, inactive, and connected states. The paging procedure may be triggered by the core network and send a paging message to the UE through the base station, or the paging procedure may be triggered by the access network and send a paging message to the UE. The paging message is used to notify System information and notify the UE to receive information such as Earthquake and Tsunami Warning System (ETWS) or Commercial Mobile Alert Service (CMAS).

The paging message may be transmitted using PDSCH transmission resources. The base station may schedule the paging message through DCI, i.e., indicate PDSCH transmission resources for transmitting the paging message through DCI. The DCI may be transmitted using PDCCH transmission resources. The UE may parse the PDSCH transmission resources from the DCI and receive the paging message using the PDSCH transmission resources.

If the DCI is used to schedule the same type of Paging message, that is, the DCI is only used to schedule the CN Paging or the RAN Paging, the base station may scramble the CRC of the DCI using the scrambling identity associated with the RRC connection state of the user equipment UE associated with the Paging message. The UE associated with the paging message may be a target UE for paging message transmission.

The base station may set different scrambling identities for the RRC connected state in which the UE is located, for example, different scrambling identities for an idle UE and a connected UE. In this way, when the DCI is only used to schedule a paging message, such as CN paging, sent to the idle UE, the scrambling may be performed by using the scrambling identifier associated with the idle UE. When the UE performs CRC descrambling of the DCI, if the UE is in a connected state, the UE cannot perform descrambling, the UE considers that paging is not performed, and then subsequent DCI decoding, paging message analysis and the like are not performed, so that the processing resources of the UE are saved, and further the electric quantity is saved.

Therefore, the scrambling identification associated with the RRC connection state of the UE is adopted to scramble the CRC of the DCI, so that the DCI scrambled by the CRC adopting different scrambling identifications is sent to the UE in different RRC connection states, the UE can only descramble the CRC of the scrambling identification associated with the UE state, the analysis of irrelevant DCI is reduced, the processing resource of the UE is saved, and the electric quantity is saved.

If the UE to which the DCI is sent is in an idle state and the paging message scheduled by the base station is CN paging, the base station may scramble the CRC of the DCI by using a scrambling identifier associated with the idle state, that is, the first identifier. Here, the first identity may be a newly set RNTI, such as CN-RNTI. The first identity is different from the P-RNTI.

When the UE in the idle state performs CRC descrambling on the DCI, the UE may perform descrambling using the first identifier associated with the idle state because the UE is in the idle state. Such as using CN-RNTI for descrambling.

When the UE in the non-idle state performs the CRC descrambling of the DCI, the UE can perform descrambling by adopting a scrambling identifier different from the first identifier, so that the descrambling cannot be successful, the UE considers that the paging is not performed, and then subsequent DCI decoding and paging message analysis and the like are not performed, so that the processing resources of the UE are saved, and the electric quantity is saved.

In the related art, the base station scrambles different types of paging messages by adopting the P-RNTI. For compatibility with a base station of the related art, the UE may perform descrambling using the first identity and the P-RNTI simultaneously, or may perform descrambling using the first identity and the P-RNTI sequentially first. Therefore, the compatibility of the UE to different scrambling modes can be improved.

If the UE to which the Paging message is sent is in a non-idle state, such as a connected state or an inactive state, and the Paging message scheduled by the base station may be a CN Paging or a RAN Paging, the base station may scramble the CRC of the DCI using the P-RNTI.

When the UE in the non-idle state performs CRC descrambling of the DCI, the UE can descramble by adopting the P-RNTI associated with the RRC connection state of the UE. Therefore, the base station can respectively send the DCI scrambled by the CRC by adopting different scrambling identifiers to the idle state UE and the non-idle state UE. The UE can only descramble the CRC associated with the state of the UE, and the analysis of irrelevant DCI is reduced, so that the processing resources of the UE are saved, and the electric quantity is saved.

In one embodiment, as shown in fig. 3, the method includes:

step 301: and responding to the DCI scheduling paging messages of the same type, and scrambling the CRC of the DCI by adopting a scrambling identifier associated with the RRC connection state paging message of the UE associated with the paging messages.

Step 302: and responding to the paging messages of different types scheduled by the DCI, and scrambling the CRC of the DCI by adopting P-RNTI.

If the DCI is used to simultaneously schedule different types of paging messages, the base station may perform CRC scrambling using the P-RNTI in the related art if the CN paging and the RAN paging are simultaneously scheduled.

After the UE tries to descramble by adopting the first identifier, if descrambling fails, CRC descrambling can be carried out by adopting the P-RNTI. Therefore, the UE can descramble successfully when the DCI has both CN paging and RAN paging, thereby reducing the DCI omission and improving the communication reliability.

In one embodiment, the method further comprises:

Here, PEI is used to indicate whether the UE listens to DCI at the PO. The paging message due to DCI scheduling in one PO is not necessarily for all UEs. Accordingly, DCI carrying PEI may be scrambled based on the RRC connection state of the UE or the type of paging message of the DCI schedule. The DCI carrying the PEI may be located outside, and the PEI may indicate whether the UE listens to the PO.

The base station may set different scrambling identities for the RRC connected state in which the UE is located, for example, different scrambling identities for an idle UE and a connected UE. Thus, when the DCI in the PO is only used to schedule the paging message sent to the non-idle UE, for the idle UE, the base station may scramble the DCI carrying the PEI by using the scrambling identifier associated with the non-idle UE. The PEI may indicate that the non-idle state UE does not listen or listen to the PO. The UE in the non-idle state descrambles the DCI carrying the PEI by adopting the scrambling identification associated with the RRC connection state of the UE, and determines the indication of the PEI, namely, does not monitor or monitor the PO, so that the processing resources of the UE are saved, and further the electric quantity is saved. And because the idle UE cannot descramble the DCI carrying the PEI, the default can be selected not to monitor the PO, so that the processing resources of the UE are saved, and further the electric quantity is saved. The idle UE may also select to monitor the PO by default, and further obtain the paging message.

The base station may set different scrambling identifiers for different types of paging messages, for example, DCI in the PO is only used for scheduling CN paging, and the base station may scramble DCI carrying the PEI by using the scrambling identifier associated with the CN paging. Since both the idle UE and the inactive UE may receive the CN Paging, the DCI carrying the PEI may be descrambled by using the scrambling identifier associated with the CN Paging, so as to determine the indication content of the PEI. If the UE cannot scramble the DCI carrying the PEI, the PO cannot be monitored by default, so that the processing resources of the UE are saved, and the electric quantity is saved.

Here, the DCI scheduling the paging message may be within the PO or may be outside the PO. The UE may listen for the DCI and descramble within the PO, or may listen for the DCI and descramble outside the PO.

As shown in fig. 4, the present exemplary embodiment provides a DCI scrambling method, which may be applied in a base station of a cellular mobile communication system, and includes:

step 401: and responding to the DCI scheduling the paging message of the same type, and scrambling the CRC of the DCI by adopting a scrambling identifier associated with the type of the paging message.

If the DCI is used to schedule a Paging message of the same type, that is, the Paging scheduling information in the DCI is only used to schedule the CN Paging or the RAN Paging, the base station may scramble the CRC of the DCI using a scrambling identifier associated with the type of the Paging message. Here, the Paging message may be classified into a CN Paging or a RAN Paging by type.

The base station may set different scrambling identities for different types of paging messages. For example, different scrambling identities may be set for the CN Paging or the RAN Paging. For example, when the paging scheduling information contained in the DCI is only used for scheduling CN paging, the scrambling may be performed with the UE associated scrambling identity in an idle state. When the UE performs CRC descrambling of the DCI, the UE may determine the type of the paging message that may be received based on the state of the UE itself, and perform descrambling using the scrambling identifier associated with the type of the paging message.

For example, when the paging scheduling information included in the DCI is only used for scheduling the CN paging, the DCI may be scrambled by using the scrambling identifier associated with the CN paging, and if the UE is in an idle state, the UE may determine that the received paging message is the CN paging, and therefore may descramble by using the scrambling identifier associated with the CN paging, and further receive the paging message. If the UE is in an idle state, the UE can determine that the paging message received by the UE is the RAN paging, so that descrambling can be performed by using a scrambling identifier associated with the RAN paging, DCI cannot be descrambled successfully, subsequent DCI decoding, paging message analysis and the like are not performed, processing resources of the UE are saved, and electric quantity is saved.

Therefore, the scrambling identification associated with the type of the paging message is adopted to scramble the CRC of the DCI, so that the DCI scrambled by the CRC through different scrambling identifications is sent to the UE in different RRC connection states, the UE can only descramble the CRC associated with the state of the UE, the analysis of irrelevant DCI is reduced, the processing resource of the UE is saved, and the electric quantity is saved.

and in response to the paging message being a core network paging message CN paging, scrambling the CRC of the DCI by adopting a second identifier, wherein the second identifier is different from the P-RNTI.

The base station may set different scrambling identities for the CN paging and the RAN paging, respectively. For example, the second identity may be set for CN Paging, and the third identity may be set for RAN Paging. For example: the second identity may be a CN-RNTI and the third identity may be a RAN-RNTI.

When the paging scheduling information contained in the DCI is only used for scheduling CN paging, CN-RNTI may be used for scrambling. The idle UE may determine that the type of the paging message that may be received is CN paging based on the state of the UE itself, and may perform descrambling using the CN-RNTI. The UE in the inactive state can descramble the DCI by adopting the CN-RNTI and the CN-RNTI because both the CN paging and the RAN paging are possible to receive. Therefore, both idle state UE and non-activated state UE can successfully resolve CN paging. The UE descrambles the DCI by using the CN-RNTI and the RAN-RNTI, the UE descrambles the DCI by using the CN-RNTI and the RAN-RNTI simultaneously, and the UE descrambles the DCI by sequentially using the CN-RNTI and the RAN-RNTI.

in response to the paging message being an access network paging message RAN paging, scrambling the DCI CRC with a third identifier; wherein the third identity is different from the second identity and the P-RNTI.

When the paging scheduling information contained in the DCI is used only for scheduling RAN paging, RAN-RNTI may be used for scrambling. The idle-state UE determines that the type of the paging message which is possibly received is CN paging based on the state of the UE, and the RAN-RNTI is adopted for descrambling, so that the paging message cannot be analyzed, the processing resource of the idle-state UE is saved, and the electric quantity is saved. Since the CN paging and the RAN paging are both likely to receive the inactive UE, the CN-RNTI and the RAN-RNTI may be used to descramble the DCI, so that the RAN paging may be successfully resolved. The UE descrambles the DCI by using the CN-RNTI and the RAN-RNTI, the UE descrambles the DCI by using the CN-RNTI and the RAN-RNTI simultaneously, and the UE descrambles the DCI by sequentially using the CN-RNTI and the RAN-RNTI.

Therefore, CRC scrambling is carried out on different DCI by adopting different scrambling identifiers, the UE can only carry out CRC descrambling on the DCI relevant to the self state, and the analysis of irrelevant DCI is reduced, so that the processing resources of the UE are saved, and the electric quantity is saved.

In one embodiment, as shown in fig. 5, the method includes:

step 501: and responding to the DCI scheduling the paging message of the same type, and scrambling the CRC of the DCI by adopting a scrambling identifier associated with the type of the paging message.

Step 502: and responding to the paging messages of different types scheduled by the DCI, and scrambling the CRC of the DCI by adopting P-RNTI.

If the DCI is used to schedule different types of paging messages, that is, the DCI is scheduled in the CN paging and the RAN paging at the same time, the base station may perform CRC scrambling using the P-RNTI in the related art.

After the UE tries to descramble by adopting the CN-RNTI and/or the RAN-RNTI, if descrambling fails, CRC descrambling can be carried out by adopting the P-RNTI. Therefore, the UE can descramble successfully when the DCI has both CN paging and RAN paging, thereby reducing the DCI omission and improving the communication reliability.

In one embodiment, the method further comprises:

In one embodiment, the DCI is located within a PO or outside the PO.

As shown in fig. 6, the present exemplary embodiment provides a DCI descrambling method, which may be applied to a UE in a cellular mobile communication system, and includes:

step 601: and descrambling the paging message by using the scrambling identifier associated with the RRC connection state of the UE according to the RRC connection state of the UE.

The communication network may send paging messages to UEs in idle, inactive, and connected states. The paging procedure may be triggered by the core network and send a paging message to the UE through the base station, or the paging procedure may be triggered by the access network and send a paging message to the UE. The paging message is used to notify the System information and notify the UE to receive an Earthquake and Tsunami Warning System (ETWS) or a Commercial Mobile Alert service (Commercial Mobile Alert Serv paging message, which may be transmitted by using PDSCH transmission resources.

The base station may schedule the paging message through DCI, i.e., indicate PDSCH transmission resources for transmitting the paging message through DCI. The DCI may be transmitted using PDCCH transmission resources. The UE may parse the PDSCH transmission resources from the DCI and receive the paging message using the PDSCH transmission resources.

Therefore, the scrambling identification associated with the RRC connection state of the UE or the type of the paging message is adopted to scramble the CRC of the DCI, so that the DCI scrambled by adopting different scrambling identifications is sent to the UE in different RRC connection states, the UE can only descramble the CRC associated with the UE in the self state, the analysis of irrelevant DCI is reduced, the processing resource of the UE is saved, and the electric quantity is saved.

If the UE as the transmission target of the paging scheduling information is in an idle state and the paging message scheduled by the base station paging scheduling information is CN paging, the base station may scramble the CRC of the DCI by using a scrambling identifier associated with the idle state, that is, the first identifier. Here, the first identity may be a newly set RNTI, such as CN-RNTI. The first identity is different from the P-RNTI.

When the UE in the idle state performs CRC descrambling on the DCI, the UE may perform descrambling using the first identifier associated with the idle state because the UE is in the idle state.

If the UE to which the Paging scheduling information is sent is in a non-idle state, such as a connected state or an inactive state, and the Paging message scheduled by the base station Paging scheduling information may be a CN Paging or a RAN Paging, the base station may scramble the CRC of the DCI using the P-RNTI.

The base station may set different scrambling identities for the CN paging and the RAN paging, respectively. For example, a first identity may be set for CN Paging and a second identity may be set for RAN Paging. For example: the second identity may be a CN-RNTI and the third identity may be a RAN-RNTI.

For the UE in the connected state, the base station may perform CRC scrambling using P-RNTI in the related art.

The UE may employ the P-RNTI for CRC descrambling. If the DCI adopts CN-RNTI and RAN-RNTI to carry out CRC scrambling, descrambling can not be successful, so that analysis of irrelevant DCI is reduced, processing resources of UE are saved, and electric quantity is saved.

In one embodiment, as shown in fig. 7, the method includes:

step 701: and descrambling the paging message by using the scrambling identifier associated with the RRC connection state of the UE according to the RRC connection state of the UE.

Step 702: and descrambling the CRC carrying the DCI of the PEI by adopting the identifier associated with the state of the UE.

In one embodiment, the method further comprises: and responding to successful descrambling of the CRC carrying the DCI of the PEI, and determining whether to monitor a predetermined PO according to the PEI.

The base station may set different scrambling identities for the RRC connected state in which the UE is located, for example, different scrambling identities for an idle UE and a connected UE. Thus, when the paging scheduling information contained in the DCI in the PO is only used to schedule the paging message sent to the non-idle-state UE, for the idle-state UE, the base station may scramble the DCI carrying the PEI using the scrambling identifier associated with the non-idle state. The PEI may indicate that the non-idle state UE does not listen or listen to the PO. The UE in the non-idle state descrambles the DCI carrying the PEI by adopting the scrambling identification associated with the RRC connection state of the UE, and determines the indication of the PEI, namely, does not monitor or monitor the PO, so that the processing resources of the UE are saved, and further the electric quantity is saved. And because the idle UE cannot descramble the DCI carrying the PEI, the default can be selected not to monitor the PO, so that the processing resources of the UE are saved, and further the electric quantity is saved. The idle UE may also select to monitor the PO by default, and further obtain the paging message.

The base station may set different scrambling identifiers for different types of paging messages, for example, paging scheduling information included in DCI in a PO is only used for scheduling CN paging, and the base station may scramble DCI carrying PEI by using the scrambling identifier associated with the CN paging. Since both the idle UE and the inactive UE may receive the CN Paging, the DCI carrying the PEI may be descrambled by using the scrambling identifier associated with the CN Paging, so as to determine the indication content of the PEI. If the UE cannot scramble the DCI carrying the PEI, the PO cannot be monitored by default, so that the processing resources of the UE are saved, and the electric quantity is saved.

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

the communication system defines two new RNTIs for idle state UE/inactive state UE for the case that paging scheduling information in DCI only schedules RAN paging or CN paging, respectively.

When there is only a CN paging for a certain type of idle UE in a PO, the base station applies a new CRC scrambling identity to the CN paging, such as: PRNTI-CN.

The idle state UE uses the new CRC scrambling identification, namely PRNTI-CN and P-RNTI, to decode the paging PDCCH;

the UE in the inactive state descrambles by using the P-RNTI instead of the PRNTI-CN, so that the paging PDCCH can not be detected, and the paging is considered to be unavailable, and the subsequent steps of DCI decoding and PDCCH paging message analysis are omitted, thereby achieving the power saving effect.

Further, if PEI (paging early indication) based on PDCCH is introduced, the non-idle UE can ignore the following POs after being identified by the PEI scrambled by the new CRC scrambling identity, and thus has a large power saving gain.

And under the condition that only RAN Paging is scheduled according to Paging scheduling information in the DCI, the base station uses PRNTI-RAN scrambling, and the inactive UE uses P-RNTI and PRNTI-RAN to descramble the Paging PDCCH.

The idle state UE omits the subsequent steps of DCI decoding and PDCCH analysis of paging messages, thereby achieving the effect of power saving.

If the paging scheduling information in the DCI schedules both RAN paging and CN paging, the power saving effect cannot be achieved, and the base station uses P-RNTI scrambling.
