Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated.

The technical solution of the embodiment of the application may be applicable to various communication systems, for example: long term evolution (Long Term Evolution, LTE) system, LTE frequency division duplex (Frequency Division Duplex, FDD) system, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) telecommunications system, fifth generation (5th Generation,5G) mobile telecommunications system, or new radio access technology (New Radio Access Technology, NR). The 5G mobile communication system may include a Non-independent Networking (NSA) and/or an independent networking (SA).

The technical solutions provided herein may also be applicable to Machine-type communications (Machine Type Communication, MTC), inter-Machine communication long term evolution (LTE-M), device-to-Device (D2D) networks, machine-to-Machine (Machine to Machine, M2M) networks, internet of things (Internet of Things, ioT) networks, or other networks. The IoT network may include, for example, an internet of vehicles. The communication modes in the internet of vehicles system are generally called as Vehicle to other devices (V2X, X may represent anything), for example, the V2X may include: vehicle-to-vehicle (Vehicle to Vehicle, V2V) communication, vehicle-to-infrastructure (Vehicle to Infrastructure, V2I) communication, vehicle-to-pedestrian communication (Vehicle to Pedestrian, V2P) or vehicle-to-network (Vehicle to Network, V2N) communication, etc.

Related terms or nouns referred to in the present application are first introduced to facilitate understanding by those skilled in the art.

(1) Paging (paging) messages

The paging message may include at least one of the following functions:

function 1, for sending a call request to a terminal device in rrc_idle state (radio resource control IDLE state); the rrc_idle state may be simply referred to as an IDLE state.

Function 2, for notifying the terminal device in idle state, inactive state and CONNECTED state (rrc_connected), that the system information is changed.

Function 3, for the earthquake and tsunami notification, i.e. instructing the terminal device to start receiving the main notification of the earthquake and tsunami warning system (Earthquake and Tsunami Warning System, ETWS) (primary notification).

Function 4, for ETWS secondary notification (secondary notification); the terminal device is instructed to start receiving public warning system (Commercial Mobile Alert System, CMAS) notifications.

For example, a terminal device in an idle state or a radio resource control Inactive state (rrc_inactive mode) may periodically receive a paging message at a fixed Paging Occasion (PO). Wherein, the rrc_inactive mode may be simply referred to as an Inactive state.

(2) Paging Occasion (PO)

Terminal devices in idle or inactive states may use discontinuous reception (Discontinuous Reception, DRX) mechanisms for reception of paging messages.

Illustratively, the DRX cycle is as shown in fig. 1, and the terminal device periodically (the cycle is the DRX cycle) listens to the PO in order to reduce power consumption. One PO may contain multiple paging listening occasions (Paging monitoring occasion, PMOs) and the number of PMOs corresponds to the number of synchronization signal blocks (Synchronization Signal Block, SSBs) configured by the base station, i.e., one SSB for each PMO. The base station needs to send the same paging message in the beam direction corresponding to each SSB, and the terminal device selects a proper PMO to monitor a physical downlink control channel (Physical Downlink Control Channel, PDCCH) and receives the paging message according to the signal quality measurement result of the SSB.

Illustratively, the signal quality measurement may be characterized by a value of a reference signal received power (Reference Signal Receiving Power, RSRP).

(3)PEI

In idle state or inactive state, one or more POs can be associated with a paging advance indication opportunity (Paging Early Indication Occasion, PEI-O), before monitoring the PO, the terminal device can monitor the PEI-O associated with the PO to acquire PEI to determine whether the PO needs to be monitored, so that the power consumption of the terminal device is saved, and the purpose of saving energy is achieved. Similarly, one PEI-O contains multiple PDCCH listening opportunities (Monitoring Occasion, MO), and the number of MOs is consistent with the number of Synchronization Signal Blocks (SSBs) configured by the base station, i.e., one SSB for each MO. The base station needs to send the same PEI in the beam direction corresponding to each SSB, and the terminal device may select a suitable MO to monitor the PDCCH and receive the PEI according to the signal quality measurement result of the SSB, and likewise, the signal quality measurement result may be represented by the value of RSRP.

(4) Random access procedure

Specifically, in the embodiment of the present application, the random access procedure may be divided into a four-step random access procedure and a two-step random access procedure according to the number of steps included. The four-step random access procedure comprises 4 steps, and the two-step random access procedure comprises two steps.

Fig. 2 is a schematic diagram of a four-step random access procedure according to an embodiment of the present application. The method specifically comprises the following steps:

s201, the terminal device sends an Msg1 (message 1), where the Msg1 includes a random access preamble for requesting access to the network. Correspondingly, the network device receives Msg1.

Wherein the resources used by the terminal device to transmit Msg1 are determined by reading SIB1 in the master information block (Master Information Block, MIB) and the system information block (System Information Blocks, SIB). In other embodiments of the present application, the random access preamble included in Msg1 may be indicated to the terminal device by the network device through SIB 1.

Specifically, MIB and SIB are sent by the network device to the terminal device.

S202, the network equipment correctly receives the Msg1 and sends the Msg2 (message 2). Wherein the Msg2 is scrambled using a radio network temporary identifier (Random Access Radio Network Temporary Identifier, RA-RNTI). For example, the Msg2 may include uplink scheduling indication information, such as Timing Advance (TA), temporary cell radio network temporary identifier (Temporary Cell Radio Network Temporary Identifier, TC-RNTI), power adjustment information, and a resource indication of the terminal device transmitting Mgs 3.

Correspondingly, the terminal device receives Msg2. Specifically, after the terminal device sends the Msg1, the RA-RNTI may be used to receive the Msg2 to descramble the message.

S203, the terminal equipment receives the Msg2 and sends Msg3 (message 3). Correspondingly, the network device receives Msg3.

Wherein Msg3 may also be referred to as an RRC connection setup request, for requesting establishment of an RRC connection. For example, the terminal device may generate Msg3 according to uplink scheduling indication information included in Msg2.

S204, the network equipment receives the Msg3 and sends Msg4 (message 4). Correspondingly, the terminal device receives Msg4.

Wherein, msg4 is used for notifying the terminal equipment of the completion of the initial access procedure. That is, the terminal device receives Msg4, and determines that the random access procedure is completed. Otherwise, the terminal equipment does not successfully receive the Msg4, and the terminal equipment determines that the random access process fails.

(5) Physical random access channel Occasion (PRACH Occasion, RO)

In this embodiment of the present application, the RO may be referred to as a physical random access channel opportunity, which may be understood as a block of time-frequency resources, used to send a random access request message to the network.

Further, one RO may be associated or mapped with one or more SSBs. Alternatively, one SSB may be associated with one or more ROs. By way of example, the mapping rules between RO and SSB may be: the SSB performs resource mapping with the RO multiplexed in the frequency domain, and then performs resource mapping with the RO multiplexed in the time domain. That is, the mapping of the SSB and the RO may be implemented in the frequency domain first, and then the mapping of the SSB and the RO may be implemented in the frequency domain.

Taking Msg 1-fdm=2 as an example, i.e. 2 ROs are multiplexed on the frequency domain, fig. 3 and 4 are schematic diagrams of the mapping of two SSBs to ROs.

As shown in fig. 3, the number of SSBs is 16, SSB-perRACH-policy=2, meaning that 2 SSBs map 1 RO, SSB1 and SSB2 map to RO1, SSB3 and SSB4 map to RO2, SSB5 and SSB6 map to RO3, SSB6 and SSB7 map to RO4, and so on, according to the mapping rule of SSB to RO.

As shown in fig. 4, the number of SSBs is 4, SSB-perRACH-occupancy=1/2, meaning that 1 SSB maps 2 ROs, so SSB1 maps to RO1 and RO2, SSB2 maps to RO3 and RO4, and so on, according to the SSB-to-RO mapping rule.

Further, in some embodiments, the RO may be configured to the terminal device by the network device. For example, the network device may configure the RO for the terminal device through SIB 1. Configuration of the RO may be achieved by including at least one of the following information as SIB 1:

the period size of ROs, the number of ROs multiplexed in the time domain within one physical random access channel (Physical Random Access Channel, PRACH) period, the number of ROs multiplexed in the frequency domain (i.e., msg1-FDM parameters), the number of SSBs associated with each RO (i.e., SSB-perRACH-allocation parameters), etc.

Fig. 5 is a schematic view of an application scenario provided in the embodiment of the present application. Referring to fig. 5, a terminal device 501 and a network device 502 are included. The terminal device 501 determines an SSB indication occasion according to the indication information sent by the network device 502, and determines a first SSB from the SSB indication occasions, so as to instruct the network device 502 to send a message from the first SSB direction, so that the network device 502 sends a paging message and/or PEI to the terminal device 501 on a listening occasion corresponding to the first SSB direction.

It is understood that the number of terminal devices 501 and network devices 502 may be plural, and not shown in the figure. The terminal device 501 may be a Mobile Phone (Mobile Phone), a tablet (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented Reality (Augmented Reality, AR) terminal device, a wireless terminal in industrial control (Industrial Control), a vehicle terminal device, a wireless terminal in Self Driving (Self Driving), a Road Side Unit (RSU), a wireless terminal in Remote Medical (Remote Medical), a wireless terminal in Smart Grid (Smart Grid), a wireless terminal in transportation security (Transportation Safety), a wireless terminal in Smart City (Smart City), a wireless terminal in Smart Home (Smart Home), a wearable terminal device, or the like. The terminal device 101 according to the embodiment of the present application may also be referred to as a terminal, a User Equipment (UE), an access terminal device, a vehicle terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a remote User Equipment, a mobile device, a wireless communication device, a UE agent, or a UE apparatus, etc.

The network device 502 is a device having a wireless transceiving function. Including but not limited to: an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, a base station (gndeb or gNB) or transceiving node (Transmission and Receiving Points, TRP) in NR, a base station in a subsequent evolution system, an access node in a wireless fidelity (Wireless Fidelity, wiFi) system, a wireless relay node, a wireless backhaul node, etc. The base station may be: macro base station, micro base station, pico base station, small station, relay station, etc.

The embodiment of the application provides a communication method, because the network device can indicate at least one RO to the terminal device, so that the terminal device can indicate part of SSBs in SSBs associated with the at least one RO to the network device, the network device can only send paging control information and/or PEI on a monitoring occasion corresponding to the SSB indicated by the terminal device, and does not need to send paging control information and/or PEI on a monitoring occasion corresponding to the SSBs associated with all ROs, thereby being beneficial to reducing energy consumption of the network device.

For example, the terminal device indicates one SSB of the at least one RO-associated SSB to the network device, and the network device sends paging control information and/or PEI on a listening occasion corresponding to this SSB indicated by the terminal device. For another example, the terminal device indicates two SSBs in the at least one RO-associated SSB to the network device, and the network device sends paging control information and/or PEI on listening occasions corresponding to the two SSBs indicated by the terminal device, respectively.

Further, in some embodiments, the portion SSB is an SSB in which signal reception qualities in at least one RO-associated SSB are ranked in order of top few bits. Alternatively, the partial SSB is an SSB having a signal reception quality greater than a certain threshold among the at least one RO-associated SSBs. Thereby increasing the probability of success of the transmission of paging control information and/or PEI to the terminal device.

The paging control information may include paging downlink control information (Downlink Control Information, DCI), a paging message, or the like.

In addition, the listening occasion corresponding to the SSB may be understood as a listening occasion where the base station uses paging control information or a paging advance indication sent by the beam direction corresponding to the SSB, or the base station uses paging control information or a paging advance indication sent by the beam direction corresponding to the different SSB at different listening occasions.

The following description will be made specifically taking an example in which the terminal device indicates an SSB to the network device. The following detailed description is given of the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following specific embodiments may exist alone or in combination with one another, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 6 is a flowchart of a communication method provided in an embodiment of the present application, where the method may be performed by a terminal device, and referring to fig. 6, the method includes the following steps.

S601, the network equipment sends first indication information, and the terminal equipment correspondingly receives the first indication information.

The first indication information is used for indicating the indication opportunity of the synchronous signal block SSB. The SSB indication opportunity includes at least one RO, that is, the SSB indication opportunity includes N ROs, where N is a positive integer greater than or equal to 1.

That is, the SSB indication occasion may be understood as one PRACH resource set or one RO set. The PRACH resource is RO, which is a time-frequency resource used for transmitting a random access request message and a random access preamble. It should be understood that, in the embodiments of the present application, the SSB indication timing may also be referred to as an SSB association timing, and the term of the SSB indication timing is not limited.

For example, the network device may carry the first indication information in system information, and indicate the SSB indication opportunity to the terminal device.

S602, the terminal equipment receives the first indication information, sends second indication information to the network equipment, and correspondingly, the network equipment receives the second indication information.

Wherein the second indication information is used for indicating the first SSB. The first SSB is one SSB of SSBs associated with N ROs.

By way of example, the terminal device may determine the first SSB from the N RO-associated SSBs based on:

the terminal equipment measures the N RO-associated SSBs to obtain the signal receiving quality of the N RO-associated SSBs. Then, the terminal device determines a first SSB from the N RO-associated SSBs based on the signal reception quality of the N RO-associated SSBs. For example, the first SSB is an SSB whose signal reception quality is greater than or equal to a first threshold among the N RO-associated SSBs. In the case where there are at least two SSBs among the N RO-associated SSBs, the signal reception quality of each of which is greater than or equal to the first threshold, the first SSB may be any one of the at least two SSBs. For another example, the first SSB may be an SSB in which signal reception qualities of N RO-associated SSBs are arranged in the order of top M bits, M being a positive integer greater than or equal to 1.

For example, signal reception quality may be characterized by RSRP. Of course, other parameters may be used for characterization, such as signal-to-noise ratio, RSSI, etc.

It should be noted that, the first threshold may be determined by the terminal device based on a certain policy or algorithm, or may be indicated to the terminal device by the network device, or may be predefined, which is not limited. For example, the first threshold may take the value of 15 decibel milliwatts (dBm).

In other embodiments of the present application, the terminal device may send the second indication information using the RO associated with the first SSB. That is, the terminal device may indicate the first SSB to the network device using the RO associated with the first SSB.

For example, the terminal device may carry the second indication information in the system information, and indicate the first SSB to the network device.

S603, the network device receives the second indication information and sends paging control information and/or PEI on a monitoring opportunity corresponding to the first SSB.

Correspondingly, the terminal device receives paging control information and/or PEI on a listening occasion corresponding to the first SSB. That is, after the terminal device sends the second indication information to the network device, paging control information and/or PEI sent by the network device may be received on a listening occasion corresponding to the first SSB.

For example, the first SSB may be an SSB associated with an RO in which the network device receives the second indication information, that is, the network device may determine the first SSB according to the RO in which the second indication information is received, and in particular, the second indication information may be a random access preamble transmitted by the terminal device.

In one example, as shown in fig. 7, the number of SSBs is 8, and a corresponding PO includes 8 PMOs, each PMO corresponds to one SSB, and assuming that, in the SSB indication opportunity associated with PO1, only the random access preamble is received on RO resources corresponding to SSB1, SSB3, and SSB4, the network device may send paging DCI on PMOs corresponding to SSB1, SSB3, and SSB4 on PO1 (i.e., PMO1, PMO3, and PMO4 in fig. 7) and send paging messages in beam directions corresponding to SSB1, SSB3, and SSB 4.

In another example, as shown in fig. 8, where the number of SSBs is 8, and the corresponding one PO includes 8 PMOs, each PMO corresponds to one SSB direction, assuming that in the SSB indication opportunity associated with PO1 and PO2 (e.g., PO1 and PO2 belong to PO group 1), only the corresponding random access preamble is received on the RO resources corresponding to SSB1, SSB3, and SSB4, the network device may send paging DCI on the PMOs corresponding to SSB1, SSB3, and SSB4 of PO group 1 (i.e., PO1 and PO2 in fig. 8), and send paging messages in the beam directions corresponding to SSB1, SSB3, and SSB 4.

In another example, as shown in fig. 9, the number of SSBs is 8, a corresponding one PO includes 8 PMOs, one PEI-O includes 8 MOs, each PMO or MO corresponds to one SSB direction, assuming that PEI-O1 associates PO1 with PO2, in the SSB indication occasion associated with PEI-O1, the network device receives the corresponding random access preamble only on RO resources corresponding to SSB1, SSB3 and SSB4, the network device transmits paging DCI on PMOs corresponding to SSB1, SSB3 and SSB4 of PEI-O1 or on MOs corresponding to SSB1, SSB3 and SSB4 of PO1/PO2, and transmits paging message in beam directions corresponding to SSB1, SSB3 and SSB 4.

In another example, as shown in fig. 10, where the number of SSBs is 8, the corresponding one PO includes 8 PMOs, one PEI-O includes 8 MOs, each PMO or MO corresponds to one SSB direction, and assuming that the network device receives the corresponding random access preamble only on RO resources corresponding to SSB1, SSB3, and SSB4 in the SSB indication opportunity associated with PEI-O1 and PEI-O2 (e.g., where PEI-O1 and PEI-O2 belong to PEI-O group 1), the network device may send the paging extraction indication on the MOs corresponding to PEI-O1 and SSB3, and SSB4 on the PEI-O2 in the PEI-O group 1, and send the paging DCI only on the PMOs corresponding to SSB1, SSB3, and SSB4 on the corresponding PEI-O group 1.

In some embodiments of the present application, when the first SSB is invalid, the terminal device may send third indication information to the network device, where the third indication information is used to indicate a second SSB, and the second SSB is one SSB of SSBs associated with N ROs in the SSB indication opportunity. Thereby facilitating the network device to timely determine the direction of the SSB sending the paging message.

That is, the first SSB is invalid, the terminal device may re-indicate the SSB to the network device, but the SSB re-indicated by the terminal device may be the same as or different from the first SSB. Specifically, the manner in which the terminal device determines the second SSB may refer to the manner in which the terminal device determines the first SSB, which is not described herein.

In one possible implementation, the manner in which the terminal device determines that the first SSB is invalid may determine whether the first SSB is valid by determining whether the first SSB is within a validity period. For example, if the first SSB is not within the validity period, the terminal device determines that the first SSB is invalid. Thereby contributing to a reduction in power consumption of the terminal device.

For example, the duration of the validity period (i.e., the validity duration) may be indicated to the terminal device by the network device. For example, the network device sends fourth indication information to the terminal device, where the fourth indication information is used to indicate the effective duration. For example, the network device may carry the fourth indication information in the system information, and indicate the effective duration to the terminal device. Alternatively, the effective duration may be predefined by the protocol.

For example, the effective duration may be P paging cycles, and the start paging cycle of the P paging cycles may be a paging cycle in which the SSB indication opportunity is located, where P is an integer greater than or equal to 1. For example, if the effective duration is 4 paging periods, the paging period where the SSB indication opportunity is located is taken as a starting paging period, and in the following 3 paging periods, the terminal device may receive the paging control information and/or PEI on the listening opportunity corresponding to the first SSB.

In another possible implementation manner, the terminal device may further select an SSB from SSBs associated with the N ROs again and indicate the selected SSB to the network device, in case the signal reception quality of the first SSB is less than the second threshold. That is, when the signal reception quality of the first SSB is poor, the first SSB is not effective. Updating the SSB indicated to the network device. Thereby facilitating the network device to determine the SSB that sent the paging message in a timely manner.

It should be noted that the foregoing description is presented by taking an example in which the terminal device indicates an SSB to the network device. In the embodiment of the application, the terminal device may also indicate at least two SSBs to the network device. Taking the example that the terminal device indicates SSB1 and SSB2 to the network device, the terminal device may send the indication information of SSB1 and the indication information of SSB2 to the network device. For example, the terminal device may indicate SSB1 to the network device using the RO associated with SSB1 and indicate SSB2 to the network device using the RO associated with SSB2.

A specific indication scheme of the SSB indication timing will be described in detail with reference to fig. 11.

Fig. 11 is a schematic flow chart of a communication method according to an embodiment of the present application, which specifically includes the following steps:

s1101, the network equipment sends first indication information, and the terminal equipment correspondingly receives the first indication information. The first indication information is used for indicating an SSB indication opportunity, wherein the SSB indication opportunity comprises at least one RO.

In one possible implementation, the network device sends configuration information to the terminal device, the configuration information including the first indication information. Correspondingly, the terminal equipment receives configuration information from the network equipment, and obtains first indication information from the configuration information.

S1102, the terminal equipment receives the first indication information and determines SSB indication time according to the first indication information.

In some embodiments of the present application, the first indication information may indicate the SSB indication opportunity by indicating a time offset and a configuration parameter of the at least one RO. It will be appreciated that the time offset may be a parameter at the cell level (i.e. a time offset is configured for a cell), or may be a parameter at the PO or PEI-O level (i.e. a time offset is configured for each PO or PEI-O separately), which is not limited in this application.

Wherein, the time offset is the time interval between the SSB indication opportunity and the reference time domain resource. The reference time domain resource may be a fixed time domain resource.

For example, the reference time domain resource may be one PO associated with the SSB indication opportunity.

For example, in the case where the PO associated with the SSB indication opportunity is one, the reference time domain resource is the PO associated with the SSB indication opportunity. Since one PO includes at least two PMOs, the reference time domain resource may be a time slot in which the first PMO in the PO associated with the SSB indication opportunity is located. As shown in fig. 12, the time interval between the SSB indication opportunity and the PO means: the time interval between the start position of the SSB indication opportunity and the start position of the time slot in which the first PMO in the POs associated with the SSB indication opportunity is located. Alternatively, the time interval between the SSB indication occasion and the PO may be: the time interval between the end position of the SSB indication opportunity and the start position of the time slot in which the first PMO in the POs associated with the SSB indication opportunity is located. The PO associated with the SSB indication occasion refers to a PO corresponding to the terminal device, that is, a PO used by the terminal device to receive the paging message in one paging cycle.

Specifically, the first PMO may be the first PMO after at least two PMOs are ordered according to the time domain position in the PO associated with the SSB indication opportunity.

For another example, in the case where the number of POs associated with the SSB indication opportunity is at least two, the reference time domain resource is one of the at least two POs associated with the SSB indication opportunity. If the reference time domain resource is the first PO of the at least two POs, the first PO may be understood as the first PO after the at least two POs associated with the SSB indication opportunity are ordered according to the time domain position. Thereby facilitating the terminal device to quickly determine the first PO to determine the location of the SSB indication opportunity. The time interval between the SSB indication opportunity and the PO may be referred to the above description, and will not be described herein.

Specifically, in the case where the number of POs associated with the SSB indication opportunity is at least two, the reference time domain resource may be a time slot in which a first PMO of a first one of the at least two POs associated with the SSB indication opportunity is located. Of course, the reference time domain resource may also be the last PO of the at least two POs, or the reference time domain resource may also be any one of the at least two POs, which is not limited in this application.

Further, in the case where the SSB indication opportunity is associated with at least two POs, the at least two POs associated with the SSB indication opportunity are consecutive in the time domain. Illustratively, SSB indication opportunities are associated with the PO group. The PO group associated with the SSB indication opportunity includes at least two POs that are contiguous in the time domain. Wherein at least two POs are time-domain continuous, it is understood that if at least two POs in the PO group are ordered by time-domain position, the order of the at least two POs is continuous. For example, a paging cycle includes 8 POs, and the number of POs included in the PO group configured by the network device is 2, as shown in fig. 13, and then the terminal device sequentially divides each two POs into a PO group according to the time domain position, where each two POs is continuous in the time domain position.

As another example, the reference time domain resource may also be one PEI-O associated with the SSB indication opportunity.

For example, in the case where the PEI-O associated with the SSB indication opportunity is one, the reference time domain resource is the PEI-O associated with the SSB indication opportunity. Since one PEI-O includes at least two MOs, the reference time domain resource may be a slot in which the first MO in the PEI-O associated with the SSB indication opportunity is located. As shown in fig. 14, the time interval between SSB indication opportunities and PEI-O refers to: the time interval between the start position of the SSB indication opportunity and the start position of the slot in which the first MO in the PEI-O associated with the SSB indication opportunity is located. Alternatively, the time interval between the SSB indication occasion and the PEI-O may be: the time interval between the end position of the SSB indication opportunity and the start position of the slot in which the first MO in the PEI-O associated with the SSB indication opportunity is located. The PEI-O related to the SSB indication occasion refers to the PEI-O related to the PO corresponding to the terminal equipment, namely the terminal equipment is used for monitoring the PEI-O of the PEI in one paging cycle.

Specifically, the first MO may be the first MO after at least two MOs are ordered according to the time domain position in PEI-O associated with the SSB indication opportunity.

For another example, in the case where the number of PEI-Os associated with the SSB indication opportunity is at least two, the reference time domain resource is one PEI-O of the at least two PEI-Os associated with the SSB indication opportunity. If the reference time domain resource is the first PEI-O of the at least two PEI-Os, the first PEI-O may be understood as the first PEI-O after the at least two PEI-Os associated with the SSB indication opportunity are ordered according to the time domain position. Thereby facilitating the terminal device to quickly determine the first PEI-O to determine the location of the SSB indication opportunity. The time interval between the SSB indication opportunity and the PEI-O may be referred to the above description, and will not be repeated here.

Specifically, in the case where the number of PEI-O associated with the SSB indication opportunity is at least two, the reference time domain resource may be a time slot in which a first MO of the first one of the at least two PEI-O associated with the SSB indication opportunity is located. Of course, the reference time domain resource may also be the last PEI-O of the at least two PEI-Os, or the reference time domain resource may also be any PEI-O of the at least two PEI-Os, which is not limited in this application.

Further, in the case where the number of PEI-O associated with the SSB indication opportunity is at least two, the at least two PEI-O associated with the SSB indication opportunity are contiguous in the time domain. Illustratively, the SSB indication opportunities are associated with the PEI-O group. The PEI-O group associated with the SSB indication occasion includes at least two PEI-Os that are contiguous in the time domain. Wherein at least two PEI-Os are temporally contiguous, it is understood that if at least two PEI-Os in the PEI-O group are ordered by temporal position, the order of the at least two PEI-Os is sequential. For example, one paging cycle includes 8 PEI-O, where the number of PEI-O included in the PEI-O group configured by the network device is 2, as shown in fig. 15, the terminal device sequentially divides each two PEI-O into one PEI-O group according to the time domain position, and each two PEI-O is continuous in the time domain position.

Furthermore, the configuration parameter of the at least one RO is used to indicate a time-frequency resource parameter of the at least one RO. For example, the at least one RO configuration parameter may indicate a time-frequency resource parameter of the at least one RO by indicating at least one of:

the SSB indicates the frequency domain starting position of the first RO of the frequency domain in the opportunity, the frequency domain resource size of the RO, the number of the RO multiplexed on the frequency domain in the opportunity, the interval between two adjacent RO on the frequency domain, and the time domain resource position occupied by the RO multiplexed on the time domain in the opportunity.

The following is the above-mentioned related time-frequency resource parameters:

SSB indicates the frequency domain start position of the first RO in the frequency domain in the opportunity: the starting position of the first RO multiplexed in the frequency domain in the SSB indication opportunity is referred to, and the frequency domain is generally in units of subchannels, and one subchannel includes a plurality of resource blocks, where the starting position may be a starting resource block or a starting subchannel, which is not limited in this application.

Frequency domain resource size of RO: the size of the frequency domain resources occupied by the ROs multiplexed on the frequency domain in the SSB indication opportunity may be specifically the size of the frequency domain resources occupied by the ROs multiplexed on each frequency domain, or the size of the frequency domain resources occupied by the ROs multiplexed on all the frequency domains in the SSB indication opportunity, where the resource size may be represented by a subchannel or a resource block.

Spacing between two adjacent ROs in the frequency domain: refers to an interval of ROs multiplexed on adjacent two frequency domains in the SSB indication occasion, which may be represented in a subchannel or a resource block.

SSB indicates the time domain resource positions occupied by ROs multiplexed in the time domain in the opportunity: the starting position of the first RO multiplexed in the time domain in the SSB indication timing may be the position of the resource occupied in the time domain in relation to the SSB indication timing, or may be the position of all ROs multiplexed in the time domain in the SSB indication timing in relation to the SSB indication timing.

It should be noted that the configuration parameter of the at least one RO may refer to at least one configuration parameter, where each configuration parameter is used to indicate a location of the corresponding RO relative to the SSB indication opportunity. Alternatively, the configuration parameter of the at least one RO may be a configuration parameter indicating a location of the at least one RO with respect to the SSB indication opportunity.

A detailed description will be given below of a specific determination manner of the mapping relationship between the at least one RO and the SSB included in the SSB indication opportunity, with reference to fig. 16.

As shown in fig. 16, a flow chart of an RO and SSB mapping method provided in an embodiment of the present application specifically includes the following steps:

s1601, the terminal device determines an SSB indication opportunity. The SSB indication opportunity includes at least one RO.

For example, the SSB indication timing is indicated to the terminal device by the network device, and the specific indication manner may be referred to the related description in the method shown in fig. 11, which is not repeated herein. Alternatively, the SSB indication occasion may be determined by the terminal device in combination with certain parameters. These certain parameters may also include parameters predefined by the protocol, and/or parameters indicated by the network device, without limitation.

S1602, the terminal equipment determines a mapping relation between at least one RO and the SSB according to the mapping rate between the SSB and the RO.

That is, the terminal device determines the SSB associated with at least one RO according to the mapping rate of the SSB and the RO.

It should be noted that the mapping ratio of SSB to RO refers to a ratio of the number of SSBs configured by the network device to the number of ROs in the SSB indication opportunity, and when the mapping ratio is 2, it means that 2 SSBs are mapped onto one RO, and when the mapping ratio is 1/2, it means that one SSB is mapped onto 2 ROs. When the second indication information sent by the terminal device to the network device includes the random access preamble, taking the mapping rate of 2 as an example, it is assumed that one RO corresponds to 64 random access preambles, SSB1 and SSB2 are mapped to one RO, at this time, the random access preamble index ranges 0-31 correspond to SSB1, and the random access preamble index ranges 32-63 correspond to SSB2.

The terminal device may obtain the mapping rate of SSB and RO based on the following manner:

mode 1: the mapping rate of SSB to RO may be indicated by the network device to the end device. Thereby enabling the terminal device to rapidly acquire the mapping rate of the SSB and the RO. For example, the network device may indicate the mapping rate of the SSB and the RO to the network device through the configuration information. For example, in the case where the SSB indication occasion is a network device indication, the network device may indicate the SSB indication occasion and the mapping rate of SSB and RO to the terminal device through the first indication information.

Mode 2: the mapping rate of SSB to RO may also be determined by the terminal device. For example, the terminal device determines the mapping rate of SSB and RO according to the number of SSBs employed in the downlink communication and the number of ROs included in the SSB indication timing. For example, one SSB indication occasion includes 8 ROs, the number of SSBs used for downlink communication is 4, and according to the physical meaning of the mapping rate, the mapping rate is determined to be 1/2, that is, one SSB is mapped to 2 ROs. Thereby helping to save the signaling overhead required to configure the mapping rate.

The foregoing is only an illustration of a specific manner in which two terminal devices obtain the mapping rates of SSB and RO, and in this embodiment of the present application, the terminal devices may also obtain the mapping rates of SSB and RO by other manners, for example, a certain parameter of the terminal device and a policy indicated by the network device may determine the mapping rates of SSB and RO, which is not limited.

In addition, the terminal device may determine the mapping relationship between at least one RO and the SSB according to the mapping rate between the SSB and the RO by:

mode 1: and the terminal equipment sequentially determines the mapping relation between at least one RO and the SSB according to the ascending order of the SSB index according to the mapping rate of the SSB and the RO.

For example, the mapping rate of SSBs to ROs is 2, that is, 2 SSBs are mapped to one RO, the number of SSBs used for downlink communications is 8, and SSB indicates that the opportunity includes 4 ROs (for example, includes 2 ROs multiplexed in the frequency domain and 2 ROs multiplexed in the time domain), and then the order of the 8 SSBs in the ascending order of the index is: the SSB1, SSB2, …, SSB8 take a mapping rule as an example of mapping of ROs multiplexed on the frequency domain first and then mapping of ROs multiplexed on the time domain, then the terminal device may determine, according to the order, a mapping relationship between SSB1 and SSB2 and any one of 2 ROs multiplexed on the frequency domain, determine a mapping relationship between SSB3 and SSB4 and another one of 2 ROs multiplexed on the frequency domain, determine a mapping relationship between SSB5 and SSB6 and any one of 2 ROs multiplexed on the time domain, and determine a mapping relationship between SSB7 and SSB8 and another one of 2 ROs multiplexed on the time domain.

Of course, it should be understood that the terminal device may sequentially determine the mapping relationship between at least one RO and SSB in descending order of SSB index. The order of determining the mapping relationship between at least one RO and SSB is not limited in the embodiments of the present application.

Mode 2: the terminal device may first sequence the at least one RO from low to high according to the frequency domain position, then sequence the at least one RO from front to back according to the time domain position, and then sequentially determine the mapping relationship between the at least one RO and the SSB according to the ascending order of the SSB index.

That is, in this manner, the terminal device may sort the at least one RO, and determine the mapping relationship of the at least one RO and the SSB at a time in the sort of the at least one RO and the ascending order of the SSB index.

Taking the example in the above mode 1 as an example, the 4 ROs are first sorted from low to high according to the frequency domain position, and then sorted from front to back according to the time domain position, and the positions of the ROs determined according to the sorting are shown in fig. 17, then the terminal device may determine the mapping relationship between SSB1 and SSB2 and the first RO multiplexed in the frequency domain, determine the mapping relationship between SSB3 and SSB4 and the second RO multiplexed in the frequency domain, determine the mapping relationship between SSB5 and SSB6 and the first RO multiplexed in the time domain, and determine the mapping relationship between SSB7 and SSB8 and the second RO multiplexed in the time domain according to the order of the 4 ROs and the ascending order of SSB indexes.

Fig. 18 is a flow chart of another communication method according to an embodiment of the present application, which specifically includes the following steps:

S1801, the terminal device determines at least one RO.

For example, the at least one RO may be indicated by the network device, and the specific indication may be referred to as indication shown in fig. 6. Alternatively, at least one RO is determined by the terminal device based on a certain policy or rule.

S1802, the terminal device indicates to the network device a partial SSB among SSBs associated with the at least one RO.

Regarding the terminal device to network device indication portion SSB, reference may be made to the description related to the terminal device to terminal device indication SSB in fig. 6, which is not described herein.

S1803, the network device sends paging related information on a listening occasion corresponding to the portion SSB indicated by the terminal device. Correspondingly, the terminal equipment receives paging related information on the monitoring occasion corresponding to the part of SSB. For example, the paging related information may include paging control information and/or PEI.

The specific manner in which the method shown in fig. 18 is related to determining the mapping relationship between at least one RO and SSB by the terminal device may be referred to the above related description, and will not be described herein.
