In the embodiments of this application, the scenarios in which network devices and terminal devices are located are not limited.

It should be understood that the communication device involved in this application may be a network device or a terminal device. For example, the first communication device is a network device, and the second communication device is a terminal device. For another example, the first communication device is a terminal device, and the second communication device is a network device. For another example, the first communication device and the second communication device are both network devices, or both are terminal devices.

It should also be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform).

With people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3rd generation mobile communications partnership project (3GPP) international standards organization began to develop 5G. The main application scenarios of 5G can include: enhanced mobile ultra-broadband (eMBB), ultra-reliable low latency communications (URLLC) and massive machine type communication (mMTC). The solutions in the embodiments of this application can be applied to any of the above scenarios.

The main characteristics of the eMBB service are the large amount of data transmitted and the high transmission rate. When transmitting eMBB service data, a longer time scheduling unit is generally used to transmit data to improve data transmission efficiency. Typical eMBB services can include: ultra-high-definition video, augmented reality (AR), virtual reality (VR), etc.

The main characteristics of the URLLC service are that it requires ultra-high reliability and ultra-low latency, and the amount of data transmitted is small and bursty. For example, without considering reliability, the transmission delay requirement of URLLC services is generally within 0.5 milliseconds. Under the premise that the reliability requirement reaches 99.999%, the transmission delay of the URLLC service is required to be within 1ms. Since the URLLC service is bursty and random, the URLLC service may not generate data packets for a long period of time, or may generate multiple data packets in a short period of time. In most cases, these data packets are Small packets (e.g., packets of size 50 bytes). Typical URLLC services can include: wireless control in industrial manufacturing or production processes, motion control of driverless cars or drones, and tactile interactive applications such as remote repair and remote surgery.

Typical features of mMTC can include: high connection density, small data volume, delay-insensitive services, low cost and long service life of the module, etc. This scenario is mainly oriented to the Internet of Things business, which places extremely high requirements on network access capabilities.

Radio resource control (RRC) status

Currently, the protocol defines three RRC states of terminal equipment: RRC connected (RRC_CONNECTED) state, RRC idle (RRC-IDLE) state, and RRC inactive (RRC-INACTIVE) state.

The RRC connection state may refer to the state in which the terminal device is in after completing the random access process and before RRC release is performed. There is an RRC connection between terminal equipment and network equipment (such as access network equipment). In the RRC connection state, the terminal device can perform data transmission with the network device, such as downlink data transmission and/or uplink data transmission. Alternatively, the terminal device may also transmit terminal device-specific data channels and/or control channels with the network device to transmit specific information or unicast information of the terminal device.

In the RRC connected state, the network device can determine the cell-level location information of the terminal device, that is, the network device can determine the cell to which the terminal device belongs. In the RRC connected state, after the terminal device moves, such as from one cell to another cell, the network device can control the terminal device to perform cell handover (handover). It can be seen that the mobility management of the terminal device in the RRC connected state may include cell handover. In addition, the mobility management of the terminal device in the RRC connected state can be controlled by the network device. Accordingly, the terminal device can switch to a designated cell according to instructions issued by the network device.

The RRC connected state refers to the state of the terminal device when it is camped in the cell but does not perform random access. The terminal device usually enters the RRC connected state after powering on or after RRC is released. In the RRC connection state, there is no RRC connection between the terminal device and the network device (such as the resident network device), the network device does not store the context of the terminal device, and no connection for the terminal device is established between the network device and the core network. If the terminal device needs to enter the RRC connected state from the RRC idle state, it needs to initiate the RRC connection establishment process.

In the RRC idle state, the core network (CN) can send paging messages to the terminal device, that is to say, the paging process can be triggered by the CN. Optionally, the paging area can also be configured by the CN. In some cases, for a terminal device in the RRC idle state, when the terminal device moves (for example, from one cell to another cell), the terminal device can initiate a cell reselection process. . In other cases, for a terminal device in the RRC idle state, when the terminal device needs to access a cell, the terminal device can initiate a cell selection process. That is to say, the mobility management of the terminal equipment in the RRC idle state may include cell reselection and/or cell selection.

The RRC inactive state is a state defined to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services. The RRC inactive state is a state between the connected state and the idle state. The terminal device has entered the RRC connection state before and then released the RRC connection with the network device, but the network device saved the context of the terminal device. In addition, the connection established between the network equipment and the core network for the terminal equipment has not been released, that is to say, the user plane bearer and control plane bearer between the RAN and the CN are still maintained, that is, there is a CN-NR connection.

In the RRC inactive state, the RAN can send a paging message to the terminal device, that is, the paging process can be triggered by the RAN. The RAN-based paging area is managed by the RAN, and the network device can know the location of the terminal device based on the RAN-based paging area level.

In some cases, for a terminal device in an RRC inactive state, when the terminal device moves (for example, moves from one cell to another cell), the terminal device may initiate a cell reselection process. In other cases, for a terminal device in an RRC inactive state, when the terminal device needs to access a cell, the terminal device may initiate a cell selection process. That is to say, the mobility management of the terminal equipment in the RRC inactive state may include cell reselection and/or cell selection.

Whether it is cell selection, cell handover or cell reselection, all can be performed based on the RRM measurement results of radio resource management (RRM) measurements. For example, when the RRM measurement results are greater than the RRM measurement threshold, the terminal device can perform cell selection, Cell handover or cell reselection. The following mainly introduces RRM measurement.

RRM measurement

RRM measurement is a type of mobility measurement. RRM measurement is also called signal measurement. As introduced above, whether it is cell selection, cell handover or cell reselection, all can be performed based on signal measurement results. Therefore, mobility measurement can be understood as the basis of mobility management. In some implementations, the terminal device can signal the synchronization/physical broadcast channel block (SSB) and/or the channel state information-reference signal (CSI-RS) sent by the network device. Measure and get the signal measurement results. The terminal device can perform mobility management operations based on the signal measurement results. Mobility management operations may include one or more of the following operations: one or more of cell selection, cell reselection, neighbor cell measurement, and RRM measurement relaxation. Neighbor cell measurement may include turning on and/or turning off neighbor cell measurement. Neighbor cell measurement and RRM measurement relaxation will be introduced in detail below.

The types of RRM measurement include same-frequency measurement and inter-frequency/inter-system (inter-RAT) measurement. Co-frequency measurement includes measuring other frequency points in the same frequency band of the current serving cell and neighboring cell frequencies that are the same as the center frequency of the frequency band supported by the serving cell. Inter-frequency/inter-system measurements include measuring neighboring cell frequencies that are different from the center frequency of the frequency band supported by the serving cell, or measuring neighboring cell frequencies that are not in the same system as the serving cell.

When the terminal device is in the RRC idle state or the RRC inactive state, there is no RRC connection between the terminal device and the network device. When the signal measurement result of the cell where the terminal device resides (also called the serving cell) is lower than a certain threshold (i.e., the signal measurement threshold above), the terminal device can configure the same frequency or different frequency according to the network device in the system message. and/or different system neighboring cell information, perform signal measurements on the serving cell and cells adjacent to the serving cell (also known as neighboring cells), and determine whether the signal measurement of the neighboring cells meets the cell reselection conditions. If the signal measurement results of the neighboring cell meet the cell reselection conditions, the terminal equipment will camp in the neighboring cell. When the terminal device is in the RRC connection state, there is an RRC connection between the terminal device and the network device, and the network device configures the terminal device through RRC signaling to perform intra-frequency, inter-frequency and/or inter-system neighbor cell measurements. The terminal device reports the signal measurements of the serving cell and neighboring cells to the network device through RRC signaling, so that the network device can switch the terminal device to a cell with better signal measurement results based on the measurement results when the terminal device is in the state.

When the terminal equipment performs cell selection or cell reselection, the selection can be based on the S criterion.

The S criterion is defined as: Srxlev>0 and Squal>0. Among them, Srxlev represents the cell selection reception level value (which can also be understood as the reference signal receiving power (RSRP) of the terminal equipment in the cell), and Squal represents the cell selection reception quality value (which can also be understood as the terminal equipment’s reference signal receiving power (RSRP) in the cell). The reference signal receiving quality (RSRQ) of the cell. If the signal measurement result of the cell meets the conditions of Srxlev>0 and Squal>0, it indicates that the cell is suitable for camping. For convenience of description, Srxlev and Squal are called S parameters below.

The calculation formula of the above S parameters can be, for example, as follows:

Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation–Qoffsettemp (Formula 1)

Squal=Qqualmeas–(Qqualmin+Qqualminoffset)–Qoffsettemp (Formula 2)

Among them, Qrxlevmeas represents the measured value of RSRP of the terminal equipment in the cell, Qqualmeas represents the measured value of RSRQ of the terminal equipment in the cell, Qrxlevmin represents the minimum reception level required by the cell (also called the minimum RSRP), and Qqualmin represents the minimum required by the cell. Reception quality (also called minimum RSRQ), Qrxlevminoffset represents the minimum reception level offset of the cell, and Qqualminoffset represents the minimum reception quality offset of the cell. The network device can send Qrxlevmeas, Qqualmeas, Qrxlevmin, Qqualmin, Qrxlevminoffset, Qqualminoffset and other parameters to the terminal device through broadcast.

Pcompensation is used to punish terminal equipment that cannot meet the maximum transmit power requirements of the cell. The calculation formula of Pcompensation is: Pcompensation=max(pmax-pumax,0)(db). pmax represents the maximum uplink transmission power allowed by the terminal equipment in the cell, and pumax represents the maximum uplink transmission power supported by the terminal equipment's capabilities.

Qoffsettemp is a penalty factor introduced for cells with multiple T300 timeouts, that is, the terminal device sends RRCSetupRequest to the cell multiple times, but does not receive the RRCSetup message. The Qoffsettemp parameter can be specified in SIB1.

The above calculation formula of the S parameter is only an example and does not limit the embodiments of the present application. In some embodiments, other formulas may also be used for the calculation formula of the S parameter. For example, the Qoffsettemp parameter may also be omitted from the calculation formula of the S parameter.

It should be noted that the above signal measurement results are used to indicate the communication quality of the terminal device. In some implementations, the above signal measurement results may include one or more of the following measurement quantities: Srxlev, Squal, reference signal received power (RSRP), reference signal received quality (reference signal received quality, RSRQ), signal to noise ratio (SNR), signal to interference plus noise ratio (SINR), received signal strength indication (RSSI), etc.

In addition, the above-mentioned signal measurement threshold may include a same-frequency measurement threshold (Sintrasearch) and an inter-frequency/inter-system measurement threshold (Snonintrasearch).

In some implementations, the above-mentioned same-frequency measurement thresholds may include: a same-frequency measurement signal amplitude threshold (SintrasearchP) and a same-frequency measurement signal strength threshold (SintrasearchQ). Among them, SintrasearchP is used to indicate the signal amplitude threshold for same-frequency measurement. SintrasearchQ is used to indicate the signal strength threshold for co-frequency measurement.

In other implementations, the above-mentioned inter-frequency/inter-system measurement thresholds may include: inter-frequency/inter-system measurement signal amplitude threshold (SnonintrasearchP) and inter-frequency/inter-system measurement signal strength threshold (SnonintrasearchQ). Among them, SnonintrasearchP is used to indicate the signal amplitude threshold for inter-frequency/inter-system measurement. SnonintrasearchQ is used to indicate the signal strength threshold for inter-frequency/inter-system measurement.

After the terminal device obtains the signal measurement result, the terminal device may also perform the first operation based on the signal measurement result. Among them, the first operation may include cell switching, cell reselection, cell selection introduced above, RRM measurement relaxation introduced below, supplementary uplink (SUL) carrier switching, 2-step random access process and 4-step One or more of the handovers in the random access procedure.

Some protocols stipulate that terminal equipment needs to perform signal measurements periodically, which results in high energy consumption of the terminal equipment, especially in certain measurement scenarios (such as when the terminal equipment is in a stationary state or when the terminal equipment moves at a low speed). There is actually no need for terminal equipment to perform signal measurements frequently. Therefore, in order to reduce the energy consumption of terminal equipment, the power saving mechanism of RRM measurement and the mechanism of RRM measurement relaxation are introduced.

Power saving mechanism for RRM measurement

The terminal device can perform signal measurement based on the S-measure (S-measure) criterion. If the signal measurement result obtained by the terminal device when performing signal measurement is greater than the signal measurement threshold, the terminal device only needs to perform signal measurement of the serving cell and does not perform service Signal measurement outside the cell; if the signal measurement result obtained by the terminal device when performing signal measurement is less than or equal to the signal measurement threshold, the terminal device performs signal measurement according to the configuration of the measurement object (measurement object, MO).

The following sections introduce the signal measurement rules followed by terminal equipment when performing same-frequency measurement and inter-frequency/different-system measurement.

In the same-frequency measurement scenario, if the signal measurement results of the serving cell satisfy: Srxlev>SIntraSearchP and Squal>SIntraSearchQ, the terminal device can choose to turn off the measurement of the same-frequency neighboring cell. Otherwise, the terminal device needs to perform the measurement of the same-frequency neighboring cell. .

For low-priority or equal-priority inter-frequency frequency points or different-technology frequency points, if the signal measurement results of the serving cell satisfy: Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, the terminal device can turn off low-priority or equal-priority inter-frequency frequency points. point or different technical frequency point.

For high-priority inter-frequency frequency points or inter-technology frequency points, if the signal measurement results of the serving cell satisfy: Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, the terminal device can perform relaxation for the high-priority inter-frequency frequency point or inter-technology frequency point. Measurement.

The above parameters SIntraSearchP, SIntraSearchQ, SnonIntraSearchP and SnonIntraSearchQ can be configured by the network device through SIB2.

RRM measures relaxation mechanisms

RRM measurement relaxation may also be called neighbor cell measurement relaxation, or neighbor cell RRM measurement relaxation. There are many ways to implement RRM measurement relaxation. For example, the terminal device can implement RRM measurement relaxation by increasing the signal measurement period (that is, reducing the number of signal measurements). For another example, the terminal device may implement RRM measurement relaxation by reducing the number of neighboring cells to be measured. For another example, the terminal device can relax the RRM measurement by reducing the number of measured frequency points.

For the RRM measurement relaxation of terminal equipment in the RRC idle state and RRC inactive state, two criteria are defined in the protocol, namely the non-cell-edge criterion and the low-mobility criterion. The terminal device can determine whether it satisfies the not-cell-edge criterion and/or the low-mobility criterion based on the signal measurement results. In the case where the terminal device satisfies the not-cell-edge criterion and/or the low-mobility criterion, the terminal device can perform RRM measurement relaxation.

The not-cell-edge criterion is mainly used to determine whether the terminal device is located at the edge cell of the serving cell. If the terminal device is located in a non-edge cell of the serving cell, the terminal device has little need for cell reselection and can relax the RRM measurement to achieve the purpose of energy saving for the terminal device. If the terminal device is located in an edge cell of the serving cell, the terminal device has a greater need for cell reselection, and the terminal device does not need to perform RRM measurement relaxation.

The not-cell-edge criterion mainly defines the signal measurement threshold. By comparing the signal measurement results with the signal measurement threshold, it can be determined whether the terminal device is in a non-edge cell location. For example, if the signal measurement result is greater than the signal measurement threshold, it means that the terminal device is in a non-edge cell position of the serving cell; if the signal measurement result is less than or equal to the signal measurement threshold, it means that the terminal device is in an edge cell position of the serving cell.

The following takes the signal measurement results as RSRP and RSRQ as an example to introduce the not-cell-edge criterion. The network device can define the two threshold values s-SearchThresholdP and s-SearchThresholdQ of the not-cell-edge criterion by configuring the cell edge evaluation (cellEdgeEvaluation) parameter to the terminal device. Among them, s-SearchThresholdP is the measurement threshold value of RSRP, and s-SearchThresholdQ is the measurement threshold value of RSRQ. The terminal device can measure the RSRP and RSRQ of the serving cell, and obtain the RSRP measurement value and the RSRQ measurement value of the serving cell. When the measured value of RSRP of the serving cell is greater than s-SearchThresholdP and the measured value of RSRQ is greater than s-SearchThresholdQ, the terminal device satisfies the not-cell-edge criterion and the terminal device can perform RRM measurement relaxation.

It should be noted that in some implementations, the s-SearchThresholdP configured on the network device is usually smaller than SIntraSearchP and SnonIntraSearchP. In other implementations, the network device configured s-SearchThresholdQ may be smaller than SIntraSearchQ and SnonIntraSearchQ.

Of course, the network device can also configure only one parameter of s-SearchThresholdP and s-SearchThresholdQ. For example, the network device may configure only s-SearchThresholdP but not s-SearchThresholdQ. In this case, the terminal device may only measure the RSRP of the serving cell. When the measured value of RSRP of the serving cell is greater than s-SearchThresholdP, the terminal device satisfies the not-cell-edge criterion, and the terminal device can perform RRM measurement relaxation. For another example, the network device may only configure s-SearchThresholdQ but not s-SearchThresholdP. In this case, the terminal device may only measure the RSRQ of the serving cell. When the measured value of RSRQ of the serving cell is greater than s-SearchThresholdQ, the terminal device satisfies the not-cell-edge criterion, and the terminal device can perform RRM measurement relaxation.

The low-mobility criterion is mainly used to determine whether the terminal device is in a low mobility state. If the terminal device is in a low mobility state, that is, the terminal device is in a relatively fixed location, the terminal device has little need for cell reselection, and the terminal device can perform RRM measurement relaxation. If the terminal device is in a high mobility state, that is, the location of the terminal device changes greatly, the terminal device has a greater need for cell reselection, and the terminal device does not need to perform RRM measurement relaxation.

Whether the terminal device is in a low mobility state can be determined based on the signal measurement results of the serving cell. For example, the terminal device can measure the signal measurement results of the serving cell at different times. If the signal measurement results of the serving cell change little at different times, that is, the signal quality of the serving cell is relatively stable, it means that the terminal device is in a low mobility state.

Taking the signal measurement result as RSRP as an example, the terminal device can measure the RSRP of the serving cell. If the RSRP of the serving cell changes very little, it means that the terminal device is in a low mobility state, and the terminal device can perform RRM measurement relaxation.

Regarding the low-mobility criterion, the terminal device can determine whether the low-mobility criterion is satisfied by determining whether the low-mobility criterion parameter is satisfied. Currently, two low mobility criterion parameters are defined in the protocol: evaluation duration t-SearchDeltaP and signal measurement threshold s-SearchDeltaP. If the signal measurement result of the serving cell is less than the signal measurement threshold s-SearchDeltaP within the t-SearchDeltaP time, it means that the terminal device meets the low-mobility criterion and the terminal device can perform RRM measurement relaxation.

In one implementation, when the terminal device satisfies the low-mobility criterion, the terminal device uses a longer measurement interval when performing signal measurements on neighboring cells. For example, a fixed scaling factor K can be used to increase the measurement interval.

In another implementation, the above low-mobility criterion can be expressed as satisfying (SrxlevRef–Srxlev)<s-SearchDeltaP within t-SearchDeltaP time, where SrxlevRef represents the signal amplitude reference value of the serving cell. Generally, the use of SrxlevRef can follow the following rules.

Rule 1: When the terminal device performs cell selection or cell reselection and the serving cell changes, the terminal device needs to set the signal reference value to the current measured value of the signal amplitude of the serving cell (i.e., Srxlev).

Rule 2: If the signal amplitude of the serving cell is greater than the signal amplitude reference value, that is, (Srxlev-SrxlevRef)>0, the terminal device needs to set the signal reference value to the current measured value of the signal amplitude of the serving cell.

Rule 3: If the measurement relaxation criteria are not met within the t-SearchDelta time (if the measurement relaxation requirements are not met, the reference value is updated to the current measurement value), the terminal device needs to set the signal reference value to the current measurement of the signal amplitude of the serving cell. value.

After completing cell selection or cell reselection, the terminal equipment needs to perform signal measurement within at least a period of time TSearchDeltaP, that is, within this time TSearchDeltaP, the terminal equipment cannot perform RRM measurement relaxation.

If the terminal device is configured with both the not-cell-edge criterion and the low-mobility criterion, the network device can also notify the terminal device of the trigger conditions for RRM measurement relaxation, and the terminal device can perform RRM measurement relaxation when the trigger conditions are met. The trigger condition may be satisfying the not-cell-edge criterion and/or the low-mobility criterion. For example, the network device can indicate to the terminal device the relationship between the not-cell-edge criterion and the low-mobility criterion. For example, the network device can indicate whether the relationship between the two is "and" or "or". If there is an "and" relationship between the two, it means that the terminal device needs to satisfy both the not-cell-edge criterion and the low-mobility criterion before it can perform RRM measurement relaxation. If there is an "OR" relationship between the two, it means that the terminal device can perform RRM measurement relaxation as long as it meets any one of the criteria (such as the not-cell-edge criterion or the low-mobility criterion).

In some embodiments, the RRM measurement relaxation criterion may also include a stationary criterion. The stationary criterion is similar to the low mobility criterion. The stationary criterion and the low mobility criterion can use different signal measurement thresholds.

The communication system in the embodiment of this application may be a non-terrestrial network (NTN) communication system. The NTN system will be introduced below.

NTN communication system

NTN uses non-terrestrial methods to provide communication services to users. Non-terrestrial means may include, for example, satellites or UAS platforms.

For terrestrial network communications, communication equipment cannot be set up for land communications in oceans, mountains, deserts and other scenarios. Alternatively, terrestrial communications typically do not cover sparsely populated areas due to the cost of setting up and operating communications equipment. Compared with terrestrial network (TN) communications, NTN has many advantages. First of all, NTN communication can not be restricted by the user's geographical area. As for the NTN communication network, there will be no geographical restrictions. In theory, satellites can orbit the earth, so every corner of the earth can be covered by satellite communications. Moreover, the area that NTN communication equipment can cover is much larger than the area covered by terrestrial communication equipment. For example, in satellite communications, a satellite can cover a large ground area. Secondly, NTN communication has great social value. NTN communication can achieve coverage at a lower cost. For example, satellite communication can be used to cover remote mountainous areas or poor and backward countries or regions at a lower cost. This allows people in these areas to enjoy advanced voice communications and mobile Internet technologies, which is conducive to narrowing the digital gap with developed areas and promoting the development of these areas. Thirdly, NTN communication has a long communication distance and does not significantly increase the communication cost. In addition, NTN communication has high stability. For example, NTN communication is not limited by natural conditions and can be used even in the case of natural disasters.

Communications satellite

According to different orbital altitudes, communication satellites can be divided into low-earth orbit (LEO) satellites, medium-earth orbit (MEO) satellites, geostationary earth orbit (GEO) satellites, and high-earth orbit (GEO) satellites. Elliptical orbit (high elliptical orbit, HEO) satellites, etc. The following describes LEO satellites and GEO satellites in detail.

The orbital altitude range of LEO satellites is 500km~1500km. The orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is small, and the transmission power requirements of the user terminal are not high.

The orbital altitude of the GEO satellite is 35786km. GEO satellites rotate around the Earth every 24 hours. The signal propagation delay for single-hop communication between users is generally 250ms.

In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites can use multiple beams to cover the ground, that is, multiple beam footprints can form a satellite coverage area (field of view of the satllite). For example, a satellite can form dozens or even hundreds of beams to cover the ground. Among them, a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

Satellite Network Architecture

NTN network can be implemented based on satellite network architecture. The satellite network architecture can include the following network elements: gateway, feeder link, service link, satellite and inter-satellite link (ISL), etc. The number of gateways can be one or more. Gateways can be used to connect satellite and terrestrial public networks. The gateway is usually located at ground level. The feeder link may be the link for communication between the gateway and the satellite. The service link may be a link for communication between the terminal device and the satellite.

The satellite network structure can be divided into transparent forwarding (transparent payload) network architecture and regenerative payload (regenerative payload) network architecture in terms of the functions it provides.

Figure 2 is a schematic diagram of a transparent forwarding network architecture. The transparent forwarding network architecture can provide wireless frequency filtering, frequency conversion and amplification functions. In the transparent forwarding network architecture, it can only provide transparent forwarding of signals without changing the waveform signal it forwards.

Figure 3 is a schematic diagram of a regeneration and forwarding network structure. The regeneration and forwarding network architecture can provide wireless frequency filtering, frequency conversion and amplification functions, as well as demodulation/decoding, routing/conversion, and encoding/modulation functions. In the regeneration and forwarding network structure, the satellite can have some or all functions of the base station. Inter-satellite links can exist under a regenerative forwarding network architecture.

RRM measurement of terminal equipment in NTN

In the terrestrial network, the signal measurement results when the terminal equipment is in the center of the cell are significantly higher than the signal measurement results when it is at the edge of the cell, as shown in Figure 4. Due to the obvious "near-far effect", in the terrestrial network, it can be determined based on the signal measurement results whether the execution conditions of the mobility management operation are met (such as whether the conditions for starting neighbor cell measurement are met).

In the NTN system, for the terminal equipment at the center of the cell and the terminal equipment at the edge of the cell, the difference in the corresponding signal measurement results is not obvious, as shown in Figure 5. If it is judged based on the signal measurement results whether the execution conditions of the mobility management operation are met, there will be a problem of inaccurate judgment. Based on this, in order to solve the problem that the "far and near effect" of signal measurement results in the NTN system is not obvious, position measurement conditions based on the location of the terminal equipment are introduced. The terminal device can perform mobility management operations while meeting the signal measurement conditions and location measurement conditions at the same time.

Taking neighbor cell measurement as an example, the terminal device can determine whether the conditions for turning off neighbor cell measurement are met based on Srxlev and Squal and combined with the location measurement results. If the position measurement result of the terminal device is less than the position measurement threshold, Srxlev is greater than the signal measurement threshold, and Squal is also greater than the signal measurement threshold, the terminal device can turn off the measurement of the neighboring cell. The position measurement result can be the distance from the terminal device to the ground reference point. The position measurement threshold in the embodiment of the present application may also be called a distance measurement threshold, and the position measurement result may also be called a distance measurement result.

Generally, when a network device configures a location measurement threshold for a terminal device, the location measurement threshold and the signal measurement threshold should match. That is, the location measurement threshold and the signal measurement threshold should correspond to the same coverage area. In this way, the terminal device can perform relevant decisions to accurately perform mobility management operations based on the location measurement threshold and the signal measurement threshold.

NTN coverage enhancement

The NTN system is simulated, evaluated and designed based on the basic assumption that the antenna gain of the terminal equipment is 0dBi. However, for some terminal devices (such as mobile phones), the actual antenna gain may be much lower than 0dBi (such as -5dBi). In addition, considering that some terminals (such as mobile phones) support linear polarization, there will be a certain polarization loss (such as 3dBi) in the actual link. Therefore, the NTN system considers introducing coverage enhancement technology for such terminals. The coverage enhancement technology may include uplink coverage enhancement and/or downlink coverage enhancement. Through coverage enhancement, the cell coverage range that the terminal device can support can be increased. Coverage enhancement in this embodiment of the present application may include uplink coverage enhancement and/or downlink coverage enhancement.

The coverage enhancement technology in the embodiments of this application includes but is not limited to one or more of the following methods: repeated transmission, transmission time interval (TTI), hybrid automatic repeat request (HARQ) repeat transmission, physical uplink shared channel (PUSCH) hopping, beamforming, power boosting, or other technologies.

In a communication system, there are different types of terminal equipment, and different types of terminal equipment have different antenna processing capabilities. Different types of terminal equipment differ in one or more of the following characteristics: antenna gain, polarization method, or polarization loss. Taking the VSAT terminal and mobile phone terminal in the NTN system as an example, the antenna processing capability of the VSAT terminal is higher than that of the mobile phone terminal. The VSAT terminal is, for example, the terminal device 211 in Figures 2 and 3. The mobile phone terminal is, for example, the terminal 212 in Figures 2 and 3.

VSAT terminal is a terminal equipment in the NTN system, which can be used for remote sensing, ranging, communication parameter measurement, etc. The antenna gain of the VSAT terminal is above 0dBi, supports circular polarization, and has no polarization loss. The antenna gain of mobile phone terminals is usually below 0dBi and supports linear polarization, but there is polarization loss. If coverage enhancement technology is not introduced, there is a significant difference in the cell coverage range supported by these two types of terminals, that is, the cell coverage range supported by VSAT terminals is larger than that supported by mobile phone terminals. That is to say, the cell coverage supported by a terminal with strong antenna processing capabilities is larger than the cell coverage supported by a terminal with low antenna processing capabilities.

It can be seen from the above description that when configuring the location measurement threshold, the network device should make the location measurement threshold match the signal measurement threshold. That is, the location measurement threshold and the signal measurement threshold should correspond to the same coverage area. For terminal devices with different antenna processing capabilities, when their signal measurement results (such as RSRP or RSRQ) are the same, their corresponding distances to the cell center should be significantly different; in other words, they are at the same location. There should be a significant difference in the signal measurement results (such as RSRP or RSRQ). At present, all terminal equipment uses the same signal measurement threshold and location measurement threshold, without considering the differences in coverage of different types of terminals, which will lead to the problem of mismatch between signal measurement conditions and location measurement conditions.

Based on this, embodiments of the present application provide a wireless communication method that can set position measurement conditions and/or signal measurement conditions according to the antenna processing capability of the terminal device, so that the position measurement conditions and signal measurement conditions can be matched, so that the terminal device Decisions related to mobility management operations can be performed more accurately.

The wireless communication method according to the embodiment of the present application will be introduced in detail below with reference to FIG. 6 and FIG. 7 .

Referring to Figure 6, in step S610, the first terminal device performs a mobility management operation based on the first condition and/or the second condition.

Referring to Figure 7, in step S710, the network device sends first configuration information to the first terminal device. The first configuration information can be used to determine the first condition and/or the second condition. That is to say, the first terminal device may determine the first condition and/or the second condition based on the first configuration information.

It should be noted that the content described below is applicable to the solutions shown in Figures 6 and 7.

The first terminal device in the embodiment of the present application may be a type of terminal device, and the first terminal device may also be called a first type of terminal device. In some embodiments, the first terminal device may include one terminal device or multiple terminal devices.

The communication system in the embodiment of the present application may also include a second terminal device. The second terminal device is of a different type than the first terminal device. The second terminal device may also be called a second type terminal device. The second terminal device may also perform mobility management operations based on the first condition and/or the second condition.

The terminal device in the embodiment of the present application may be a terminal device in the RRC-IDLE state, or may be a terminal device in the RRC-INACTIVE state.

In some embodiments, the first terminal device may be a terminal device with poor antenna processing capabilities. The second terminal device may be a terminal device with strong antenna processing capabilities. For example, the first terminal device may meet one or more of the following conditions: antenna gain is less than a preset threshold, polarization type is linear polarization, and has polarization loss. The second terminal device may meet one or more of the following conditions: the antenna gain is not less than a preset threshold, the polarization type is circular polarization, and there is no polarization loss.

In some embodiments, the first terminal device may be a mobile phone terminal device, and the second terminal device may be a VSAT terminal device. In some embodiments, the antenna gain of the first terminal device is less than the preset threshold, and the antenna gain of the second terminal device is not less than the preset threshold. The preset threshold may be a predefined value, for example, the preset threshold may be 0 dBi. The preset threshold can also be a value configured by the network. In some embodiments, the polarization type of the first terminal device is linear polarization and has polarization loss. The polarization type of the second terminal device is circular polarization, and there is no polarization loss. In some embodiments, the antenna gain of the first terminal device is less than a preset threshold, and the polarization type is linear polarization. The antenna gain of the second terminal device is not less than the preset threshold, and the polarization type is circular polarization. The preset threshold may be a predefined value, for example, the preset threshold may be 0 dBi.

Mobility management operations may include one or more of the following operations: neighbor cell measurement, neighbor cell RRM measurement relaxation, cell selection, and cell reselection. Neighbor cell measurement can also be understood as neighbor cell RRM measurement. Neighbor cell measurement may include turning on neighbor cell measurement and/or turning off neighbor cell measurement.

The first terminal device performs a mobility management operation according to the first condition and/or the second condition, which may include the first terminal device determining whether to enable neighbor cell measurement according to the first condition and/or the second condition; or may include the first The terminal device determines whether to turn off neighbor cell measurement according to the first condition and/or the second condition; or it may include the first terminal device determining whether to relax the neighbor cell RRM measurement according to the first condition and/or the second condition; or it may include The first terminal device selects a cell according to the first condition and/or the second condition; or it may include the first terminal device performing cell reselection according to the first condition and/or the second condition.

The first condition and the second condition are introduced in detail below.

first condition

The first condition may be a position measurement condition, or the first condition is also called a distance measurement condition. The first condition is associated with a position measurement result of the first terminal device. In some embodiments, the first condition may include a relationship between a position measurement result and a position measurement threshold. In other embodiments, the first condition may include a relationship between the adjustment value of the position measurement result and the position measurement threshold. For example, the first condition may include one or more of the following: the position measurement result is greater than or equal to the position measurement threshold, the position measurement result is less than the position measurement threshold, the adjustment value of the position measurement result is greater than or equal to the position measurement threshold, the position measurement result is The adjustment value is less than the position measurement threshold.

The first condition can be set according to the content of specific mobility management operations. For example, if the mobility management operation includes turning on neighbor cell measurement, the first condition may include that the location measurement result is greater than or equal to the location measurement threshold, or the adjustment value of the location measurement result is greater than or equal to the location measurement threshold. For another example, if the mobility management operation includes turning off neighbor cell measurement, the first condition may include that the location measurement result is less than the location measurement threshold, or the adjustment value of the location measurement result is less than the location measurement threshold. For another example, if the mobility management operation includes performing neighboring cell RRM measurement relaxation, the first condition may include that the location measurement result is less than the location measurement threshold, or the adjustment value of the location measurement result is less than the location measurement threshold. For another example, if the mobility management operation includes not performing neighboring cell RRM measurement relaxation, the first condition may include that the location measurement result is greater than or equal to the location measurement threshold, or the adjustment value of the location measurement result is greater than or equal to the location measurement threshold. For another example, if the mobility management operation includes cell selection and/or cell reselection, the first condition may include that the location measurement result is less than the location measurement threshold, or the adjustment value of the location measurement result is less than the location measurement threshold.

For different mobility management operations, the corresponding location measurement thresholds may be the same or different. This is not specifically limited in the embodiments of the present application. For example, the relaxed location measurement thresholds for neighboring cell measurement and neighboring cell RRM measurement are different. For another example, the location measurement thresholds corresponding to cell selection and cell reselection may be the same or different.

The terminal device in the embodiment of the present application may be a terminal device in the NTN communication system. Network equipment in the NTN communication system can be satellites or ground base stations.

The position measurement results may include one or more of the following information: the distance between the terminal device and the satellite ground reference point, the distance between the terminal device and the satellite, the angle of the terminal device relative to the satellite, the propagation time from the terminal device to the satellite extension. If the location measurement result includes a distance between the terminal device and a reference point or network device, the location measurement threshold may include a distance threshold. If the position measurement result includes the angle of the terminal device relative to the network device, the position measurement threshold may include an angle threshold. If the location measurement result includes a propagation delay from the terminal device to the network device, the location measurement threshold may include a propagation delay threshold. The angle of the terminal device relative to the satellite may be the elevation angle of the terminal device relative to the satellite. The propagation delay from the terminal device to the satellite may include the one-way propagation delay and/or the two-way propagation delay from the terminal device to the satellite.

The first condition in the embodiment of the present application is related to the antenna processing capability of the first terminal device. If the antenna processing capabilities of the first terminal device and the second terminal device are different, the first condition corresponding to the first terminal device and the first condition corresponding to the second terminal device may be different or the same. For example, for a scenario where the serving cell does not support coverage enhancement, since the antenna processing capabilities of the first terminal device and the second terminal device are different, the coverage ranges supported by the first terminal device and the second terminal device are different. In this case, the first terminal device and the second terminal device support different coverage ranges. The first condition corresponding to one terminal device and the first condition corresponding to the second terminal device may be different, so that the first terminal device and the second terminal device can more accurately perform relevant decisions on the mobility management operation. Of course, in some embodiments, if the serving cell supports coverage enhancement, that is, the serving cell introduces coverage enhancement technology for the first terminal device, then the coverage ranges supported by the first terminal device and the second terminal device are consistent. In this case, The first condition corresponding to the first terminal device and the first condition corresponding to the second terminal device may be the same.

It should be noted that the coverage enhancement technology in the embodiments of this application is only targeted at terminal devices with poor antenna processing capabilities. For example, this embodiment of the present application may only perform coverage enhancement on the first terminal device, but not the second terminal device.

In some embodiments, the first condition may include a relationship between a location measurement result of the terminal device and a location measurement threshold. If the antenna processing capabilities of the first terminal device and the second terminal device are different, the first position measurement threshold of the first terminal device and the second position measurement threshold of the second terminal device may be different. By setting different location measurement thresholds, the first terminal device and the second terminal device can be caused to perform mobility management operations at different locations, thereby more accurately performing relevant decisions on mobility management operations. If the antenna processing capability of the first terminal device is lower than the antenna processing capability of the second terminal device, the first position measurement threshold may be lower than the second position measurement threshold.

The second location measurement threshold may be a threshold configured by the network device. For example, the network device may send the second location measurement threshold to the terminal device (including the first terminal device and the second terminal device) in a broadcast manner. Different mobility management operations may correspond to different second location measurement thresholds. For example, neighbor cell measurement may correspond to a second location measurement threshold, and the second location measurement threshold may be used to evaluate whether to initiate neighbor cell measurement. For another example, the neighboring cell RRM measurement relaxation may correspond to a second position measurement threshold. The second position measurement threshold may be used to evaluate whether to perform the neighboring cell RRM measurement relaxation. That is, the second position measurement threshold may be used to evaluate one or more of the following criteria. One: not at cell edge criterion, low mobility criterion, stationary criterion. For another example, cell selection may correspond to a second location measurement threshold, and the second location measurement threshold may be used for cell selection. For another example, cell reselection may correspond to a second location measurement threshold, and the second location measurement threshold may be used for cell reselection.

The first location measurement threshold may be a threshold configured by the network device, or the first location measurement threshold may be a threshold predefined in the protocol, or the first location measurement threshold may be a threshold calculated by the first terminal.

Different mobility management operations may correspond to different first location measurement thresholds. For example, neighbor cell measurement may correspond to a first location measurement threshold, and the first location measurement threshold may be used to evaluate whether to initiate neighbor cell measurement. For another example, the neighboring cell RRM measurement relaxation may correspond to a first position measurement threshold. The first position measurement threshold may be used to evaluate whether to perform the neighboring cell RRM measurement relaxation. That is, the first position measurement threshold may be used to evaluate one or more of the following criteria. One: not at cell edge criterion, low mobility criterion, stationary criterion. For another example, cell selection may correspond to a first location measurement threshold, and the first location measurement threshold may be used for cell selection. For another example, cell reselection may correspond to a first location measurement threshold, and the first location measurement threshold may be used for cell reselection. The first terminal device may determine the first location measurement threshold corresponding to each mobility management operation for different mobility management operations.

If the first location measurement threshold is a threshold configured by the network device, the network device may configure one location measurement threshold for the first terminal device, or may configure multiple location measurement thresholds. That is to say, the above first configuration information may include one position measurement threshold, or may include multiple position measurement thresholds. The network device may send the location measurement threshold to the first terminal device in a broadcast manner. If the network device configures a location measurement threshold for the first terminal device, all first terminal devices use the same first location measurement threshold. If the network device configures multiple location measurement thresholds for the first terminal device, the first terminal device may determine the first location measurement threshold from the multiple location measurement thresholds based on antenna gain and/or polarization loss.

If the first position measurement threshold is a predefined threshold in the protocol, one position measurement threshold or multiple position measurement thresholds may be predefined for the first terminal device in the protocol. If a position measurement threshold is predefined for the first terminal device in the protocol, all first terminal devices use the same first position measurement threshold. If multiple location measurement thresholds are predefined for the first terminal device in the protocol, the first terminal device may determine the first location measurement threshold from the multiple location measurement thresholds based on antenna gain and/or polarization loss.

The multiple position measurement thresholds described above may be associated with different antenna gains and/or polarization losses. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, thereby mapping the first terminal device to multiple levels, and each level corresponds to a position measurement threshold. The first terminal device may select a position measurement threshold corresponding to its own antenna gain and/or polarization loss from a plurality of position measurement thresholds based on its own antenna gain and/or polarization loss.

In some embodiments, the first position measurement threshold may be determined based on the second position measurement threshold. That is to say, the first terminal device may determine the first position measurement threshold based on the second position measurement threshold. The embodiment of the present application does not specifically limit the calculation method of the first position measurement threshold. For example, the first position measurement threshold may be determined based on the second position measurement threshold and the first offset value. That is to say, the first terminal device can determine the first position measurement threshold according to the second position measurement threshold and the first offset value. In some embodiments, the first position measurement threshold=the second position measurement threshold+the first offset value, or the first position measurement threshold=the second position measurement threshold-the first offset value. The first offset value may be greater than 0 or less than 0, and the size of the first offset value may be designed according to the actual situation.

If the first location measurement threshold is determined based on the second location measurement threshold, the network device may send indication information to the first terminal device to indicate whether the first terminal device needs to add the first offset when determining the first location measurement threshold. value. If the indication information indicates that the first offset value needs to be added, the first terminal device determines the first location measurement threshold based on the second location measurement threshold and the first offset value. If the indication information indicates that there is no need to add the first offset value, the first terminal device may use the second position measurement threshold as the first position measurement threshold. The indication information may be indication information indicating whether the cell supports coverage enhancement. If the cell does not support coverage enhancement, the first location measurement threshold may be determined based on the first location measurement threshold and the first offset value. If the cell supports coverage enhancement, the first location measurement threshold is equal to the second location measurement threshold.

The first offset value may be an offset value configured by the network device, or may be a predefined offset value in the protocol, or may be an offset value calculated by the first terminal device. For example, the network device may send the first offset value to the first terminal device in a broadcast manner.

If the first offset value is an offset value configured by the network device, the network device may configure one offset value for the first terminal device, or may configure multiple offset values. That is to say, the above first configuration information may include one offset value or may include multiple offset values. The network device may send the offset value to the first terminal device in a broadcast manner. If the network device configures an offset value for the first terminal device, all first terminal devices use the same first offset value. If the network device configures multiple offset values for the first terminal device, the first terminal device may determine the first offset value from the multiple offset values according to the antenna gain and/or polarization loss.

If the first offset value is a predefined offset value in the protocol, one offset value or multiple offset values may be predefined for the first terminal device in the protocol. If an offset value is predefined for the first terminal device in the protocol, all first terminal devices use the same first offset value. If multiple offset values are predefined for the first terminal device in the protocol, the first terminal device may determine the first offset value from the multiple offset values according to the antenna gain and/or polarization loss.

The plurality of offset values described above may be associated with different antenna gains and/or polarization losses. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, so that the first terminal device is mapped to multiple levels, and each level corresponds to an offset value. The first terminal device may select a first offset value corresponding to its own antenna gain and/or polarization loss from a plurality of offset values according to its own antenna gain and/or polarization loss.

In some embodiments, the first offset value may be determined based on the first information. The first information includes one or more of the following information: the antenna gain of the first terminal device, the polarization loss of the first terminal device, and the compensation value of the network device configuration.

In some embodiments, the first information may include one or more of the following information: the difference between the antenna gain of the first terminal device and the antenna gain reference value, the polarization loss and polarization of the first terminal device. The difference between the loss reference values and the compensation value configured by the network device.

It should be noted that different first offset values may correspond to different mobility management operations. The first terminal device may determine the first offset value corresponding to each mobility management operation for different mobility management operations.

In some embodiments, the first condition corresponding to the first terminal device may include a relationship between the adjustment value of the position measurement result and the position measurement threshold. For example, the first condition may include that the adjustment value of the position measurement result is greater than the position measurement threshold. For another example, the first condition may include that the adjustment value of the position measurement result is less than the position measurement threshold. In some embodiments, the first condition corresponding to the first terminal device includes the relationship between the adjustment value of the position measurement result and the position measurement threshold, and the first condition corresponding to the second terminal device includes the relationship between the position measurement result and the position measurement threshold. corresponding relationship. That is to say, the first terminal device can perform mobility management operations based on the adjustment value of the location measurement result and the first location measurement threshold, and the second terminal device can perform mobility management based on the location measurement result and the second location measurement threshold. operate. In some embodiments, the first position measurement threshold and the second position measurement threshold may be equal.

In some embodiments, the adjustment value of the position measurement result may be determined based on the position measurement result and the second offset value. For example, the adjustment value of the position measurement result=the position measurement result+the second offset value, or the adjustment value of the position measurement result=the position measurement result-the second offset value. The second offset value can be greater than 0 or less than 0, and the size of the second offset value can be designed according to the actual situation.

In some embodiments, the network device may send indication information to the first terminal device to indicate whether the first terminal device needs to add a second offset value when determining the position measurement result. If the indication information indicates that a second offset value needs to be added, the first terminal device determines the adjustment value of the position measurement result according to the position measurement result and the second offset value. If the indication information indicates that there is no need to add the second offset value, the first terminal device does not need to determine the adjustment value of the position measurement result and can directly use the position measurement result. The indication information may be indication information indicating whether the cell supports coverage enhancement. If the cell does not support coverage enhancement, the first terminal device may determine the adjustment value of the location measurement result based on the location measurement result and the second offset value. If the cell supports coverage enhancement, the first terminal device can directly use the location measurement results.

The second offset value may be an offset value configured by the network device, or may be a predefined offset value in the protocol, or may be an offset value calculated by the first terminal device. For example, the network device may send the second offset value to the first terminal device in a broadcast manner.

If the second offset value is an offset value configured by the network device, the network device may configure one offset value for the first terminal device, or may configure multiple offset values. That is to say, the above first configuration information may include one offset value or may include multiple offset values. The network device may send the offset value to the first terminal device in a broadcast manner. If the network device configures an offset value for the first terminal device, all first terminal devices use the same second offset value. If the network device configures multiple offset values for the first terminal device, the first terminal device may determine the second offset value from the multiple offset values according to the antenna gain and/or polarization loss.

If the second offset value is a predefined offset value in the protocol, one offset value or multiple offset values may be predefined for the first terminal device in the protocol. If an offset value is predefined for the first terminal device in the protocol, all first terminal devices use the same second offset value. If multiple offset values are predefined for the first terminal device in the protocol, the first terminal device may determine the second offset value from the multiple offset values according to the antenna gain and/or polarization loss.

The plurality of offset values described above may be associated with different antenna gains and/or polarization losses. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, so that the first terminal device is mapped to multiple levels, and each level corresponds to an offset value. The first terminal device may select a second offset value corresponding to its own antenna gain and/or polarization loss from a plurality of offset values according to its own antenna gain and/or polarization loss.

In some embodiments, the second offset value may be determined based on the second information. The second information includes one or more of the following information: the antenna gain of the first terminal device, the polarization loss of the first terminal device, and the compensation value of the network device configuration.

In some embodiments, the second information may include one or more of the following information: the difference between the antenna gain of the first terminal device and the antenna gain reference value, the polarization loss and polarization of the first terminal device. The difference between the loss reference values and the compensation value configured by the network device.

It should be noted that different second offset values may correspond to different mobility management operations. The first terminal device may determine the second offset value corresponding to each mobility management operation respectively for different mobility management operations.

In this embodiment of the present application, the terminal device can determine the first condition for use according to its type. For example, the terminal device can determine the location measurement threshold to use based on its type. If the type of the terminal device is the first terminal device type, the terminal device may use the first position measurement threshold. If the type of the terminal device is a second terminal device type, the terminal device may use the second position measurement threshold. For another example, the terminal device can determine whether to use the adjustment value of the position measurement result according to its type. If the type of the terminal device is the first terminal device type, the terminal device may use the adjustment value of the position measurement result. If the type of the terminal device is the second terminal device type, the terminal device can directly use the position measurement result.

In this embodiment of the present application, regardless of whether the cell supports coverage enhancement (the cell only performs coverage enhancement for the first terminal device), the coverage range supported by the second terminal device remains unchanged. Therefore, the network device can be the second terminal device. Configure a second position measurement threshold, which can save network device configuration overhead.

The first condition is introduced in detail above, and the second condition is introduced below.

second condition

The second condition may be a signal measurement condition. The second condition is associated with the signal measurement result of the first terminal device. In some embodiments, the second condition may include a relationship between a signal measurement result and a signal measurement threshold. In other embodiments, the second condition may include a relationship between the adjustment value of the signal measurement result and the signal measurement threshold. The second condition may include, for example, one or more of the following: the signal measurement result is greater than the signal measurement threshold, the signal measurement result is less than or equal to the signal measurement threshold, the adjustment value of the signal measurement result is greater than the signal measurement threshold, the adjustment value of the signal measurement result Less than or equal to the signal measurement threshold.

The second condition can be set according to the content of specific mobility management operations. For example, if the mobility management operation includes turning on neighbor cell measurement, the second condition may include that the signal measurement result is less than or equal to the signal measurement threshold, or the adjustment value of the signal measurement result is less than or equal to the signal measurement threshold. For another example, if the mobility management operation includes turning off neighbor cell measurement, the second condition may include that the signal measurement result is greater than the signal measurement threshold, or the adjustment value of the signal measurement result is greater than the signal measurement threshold. For another example, if the mobility management operation includes performing neighboring cell RRM measurement relaxation, the second condition may include that the signal measurement result is greater than the signal measurement threshold, or the adjustment value of the signal measurement result is greater than the signal measurement threshold. For another example, if the mobility management operation includes not performing neighboring cell RRM measurement relaxation, the second condition may include that the signal measurement result is less than or equal to the signal measurement threshold, or the adjustment value of the signal measurement result is less than or equal to the signal measurement threshold. For another example, if the mobility management operation includes cell selection and/or cell reselection, the second condition may include the signal measurement result being greater than or equal to the signal measurement threshold, or the adjustment value of the signal measurement result being greater than or equal to the signal measurement threshold.

For different mobility management operations, the corresponding signal measurement thresholds may be the same or different, and this is not specifically limited in the embodiments of the present application. For example, the relaxed signal measurement thresholds for neighboring cell measurement and neighboring cell RRM measurement are different. For another example, the signal measurement thresholds corresponding to cell selection and cell reselection may be the same or different.

The signal measurement results may include one or more of the following: RSRP, RSRQ, cell selection reception level value Srxlev, cell selection reception quality value Squal. If the signal measurement result is RSRP, the signal measurement threshold is the RSRP threshold. If the signal measurement result is RSRQ, the signal measurement threshold is the RSRQ threshold. If the signal measurement result is Srxlev, the signal measurement threshold is the Srxlev threshold. If the signal measurement result is Squal, the signal measurement threshold is the Squal threshold.

The signal measurement results may be different for different mobility management operations. For example, for neighbor cell measurement, the signal measurement result may be Srxlev and/or Squal. For the low mobility criterion in neighbor cell RRM measurement relaxation, the signal measurement result can be Srxlev. For the not-at-cell-edge criterion in neighbor cell RRM measurement relaxation, the signal measurement result can be RSRP and/or RSRQ. For cell selection and cell reselection, the signal measurement result may be Srxlev and/or Squal.

The second condition in the embodiment of the present application is related to the antenna processing capability of the first terminal device. If the antenna processing capabilities of the first terminal device and the second terminal device are different, the second condition corresponding to the first terminal device and the second condition corresponding to the second terminal device may be different or the same. For example, in a scenario where the serving cell does not support coverage enhancement, the second condition corresponding to the first terminal device and the second condition corresponding to the second terminal device may be the same. For another example, if the serving cell supports coverage enhancement, that is, the serving cell introduces coverage enhancement technology for the first terminal device, then the coverage range supported by the first terminal device and the second terminal device is the same, but because the first terminal device and the second terminal device The antenna processing capabilities of the devices are different. At the same location, the RSRP value measured by the first terminal device is lower than the RSRP value measured by the second terminal device. Therefore, in this case, the second condition corresponding to the first terminal device and the second The second conditions corresponding to the terminal devices may be different, so that the first terminal device and the second terminal device can more accurately perform relevant decisions on the mobility management operation.

In some embodiments, the second condition may include a relationship between a signal measurement result of the terminal device and a signal measurement threshold. If the antenna processing capabilities of the first terminal device and the second terminal device are different, the first signal measurement threshold of the first terminal device and the second signal measurement threshold of the second terminal device may be different. By setting different signal measurement thresholds, the first terminal device and the second terminal device can more accurately perform relevant decisions on mobility management operations. If the antenna processing capability of the first terminal device is lower than the antenna processing capability of the second terminal device, the first signal measurement threshold may be lower than the second signal measurement threshold.

The second signal measurement threshold may be a threshold configured by the network device. For example, the network device may send the second signal measurement threshold to the terminal device (including the first terminal device and the second terminal device) in a broadcast manner. Different mobility management operations may correspond to different second signal measurement thresholds. For example, neighbor cell measurement may correspond to a second signal measurement threshold, and the second signal measurement threshold may be used to evaluate whether to initiate neighbor cell measurement. For another example, the neighboring cell RRM measurement relaxation may correspond to a second signal measurement threshold. The second signal measurement threshold may be used to evaluate whether to perform neighboring cell RRM measurement relaxation. That is, the first signal measurement threshold may be used to evaluate one or more of the following criteria. One: not at cell edge criterion, low mobility criterion, stationary criterion. For another example, cell selection may correspond to a second signal measurement threshold, and the second signal measurement threshold may be used for cell selection. For another example, cell reselection may correspond to a second signal measurement threshold, and the second signal measurement threshold may be used for cell reselection.

The first signal measurement threshold may be a threshold configured by the network device, or the first signal measurement threshold may be a threshold predefined in the protocol, or the first signal measurement threshold may be a threshold calculated by the first terminal.

Different mobility management operations may correspond to different first signal measurement thresholds. For example, neighbor cell measurement may correspond to a first signal measurement threshold, and the first signal measurement threshold may be used to evaluate whether to start neighbor cell measurement. For another example, the neighboring cell RRM measurement relaxation may correspond to a first signal measurement threshold. The first signal measurement threshold may be used to evaluate whether to perform neighboring cell RRM measurement relaxation. That is, the first signal measurement threshold may be used to evaluate one or more of the following criteria. One: not at cell edge criterion, low mobility criterion, stationary criterion. For another example, cell selection may correspond to a first signal measurement threshold, and the first signal measurement threshold may be used for cell selection. For another example, cell reselection may correspond to a first signal measurement threshold, and the first signal measurement threshold may be used for cell reselection. The first terminal device may determine the first signal measurement threshold corresponding to each mobility management operation for different mobility management operations.

If the first signal measurement threshold is a threshold configured by the network device, the network device may configure one signal measurement threshold for the first terminal device, or may configure multiple signal measurement thresholds. That is to say, the above first configuration information may include one signal measurement threshold, or may include multiple signal measurement thresholds. The network device may send the signal measurement threshold to the first terminal device in a broadcast manner. If the network device configures a signal measurement threshold for the first terminal device, all first terminal devices use the same first signal measurement threshold. If the network device configures multiple signal measurement thresholds for the first terminal device, the first terminal device may determine the first signal measurement threshold from the multiple signal measurement thresholds based on the antenna gain and/or polarization loss.

If the first signal measurement threshold is a predefined threshold in the protocol, one signal measurement threshold or multiple signal measurement thresholds may be predefined for the first terminal device in the protocol. If a signal measurement threshold is predefined for the first terminal device in the protocol, all first terminal devices use the same first signal measurement threshold. If multiple signal measurement thresholds are predefined for the first terminal device in the protocol, the first terminal device may determine the first signal measurement threshold from the multiple signal measurement thresholds based on the antenna gain and/or polarization loss.

The multiple signal measurement thresholds described above may be associated with different antenna gains and/or polarization losses. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, thereby mapping the first terminal device to multiple levels, and each level corresponds to a signal measurement threshold. The first terminal device may select a signal measurement threshold corresponding to its own antenna gain and/or polarization loss from multiple signal measurement thresholds based on its own antenna gain and/or polarization loss.

In some embodiments, the first signal measurement threshold may be determined based on the second signal measurement threshold. That is to say, the first terminal device may determine the first signal measurement threshold based on the second signal measurement threshold. The embodiment of the present application does not specifically limit the calculation method of the first signal measurement threshold. For example, the first signal measurement threshold may be determined based on the second signal measurement threshold and the third offset value. That is to say, the first terminal device can determine the first signal measurement threshold according to the second signal measurement threshold and the third offset value. In some embodiments, the first signal measurement threshold=the second signal measurement threshold+the third offset value, or the first signal measurement threshold=the second signal measurement threshold-the third offset value. The third offset value can be greater than 0 or less than 0, and the size of the third offset value can be designed according to the actual situation.

If the first signal measurement threshold is determined based on the second signal measurement threshold, the network device may send indication information to the first terminal device to indicate whether the first terminal device needs to add a third offset when determining the first signal measurement threshold. value. If the indication information indicates that a third offset value needs to be added, the first terminal device determines the first signal measurement threshold based on the second signal measurement threshold and the third offset value. If the indication information indicates that there is no need to add the third offset value, the first terminal device may use the second signal measurement threshold as the first signal measurement threshold. The indication information may be indication information indicating whether the cell supports coverage enhancement. If the cell supports coverage enhancement, the first signal measurement threshold may be determined based on the first signal measurement threshold and the third offset value. If the cell does not support coverage enhancement, the first signal measurement threshold is equal to the second signal measurement threshold.

The third offset value may be an offset value configured by the network device, or may be a predefined offset value in the protocol, or may be an offset value calculated by the first terminal device. For example, the network device may send the third offset value to the first terminal device in a broadcast manner.

If the third offset value is an offset value configured by the network device, the network device may configure one offset value for the first terminal device, or may configure multiple offset values. That is to say, the above first configuration information may include one offset value or may include multiple offset values. The network device may send the offset value to the first terminal device in a broadcast manner. If the network device configures an offset value for the first terminal device, all first terminal devices use the same third offset value. If the network device configures multiple offset values for the first terminal device, the first terminal device may determine the third offset value from the multiple offset values according to the antenna gain and/or polarization loss.

If the third offset value is a predefined offset value in the protocol, one offset value or multiple offset values may be predefined for the first terminal device in the protocol. If an offset value is predefined for the first terminal device in the protocol, all first terminal devices use the same third offset value. If multiple offset values are predefined for the first terminal device in the protocol, the first terminal device may determine the third offset value from the multiple offset values according to the antenna gain and/or polarization loss.

The plurality of offset values described above may be associated with different antenna gains and/or polarization losses. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, so that the first terminal device is mapped to multiple levels, and each level corresponds to an offset value. The first terminal device may select a third offset value corresponding to its own antenna gain and/or polarization loss from a plurality of offset values according to its own antenna gain and/or polarization loss.

In some embodiments, the third offset value may be determined based on the third information. The third information includes one or more of the following information: the antenna gain of the first terminal device, the polarization loss of the first terminal device, and the compensation value of the network device configuration.

In some embodiments, the third information may include one or more of the following information: the difference between the antenna gain of the first terminal device and the antenna gain reference value, the polarization loss and polarization of the first terminal device. The difference between the loss reference values and the compensation value configured by the network device.

For example, the third offset value=max{0, AnteGain_ref-AnteGain_UE}. For another example, the third offset value={0, PolarizationLoss_ref–PolarizationLoss_UE}. For another example, the third offset value=max{0,AnteGain_ref–AnteGain_UE}+max{0,PolarizationLoss_ref–PolarizationLoss_UE}. For another example, the third offset value=max{0,(AnteGain_ref–AnteGain_UE)+(PolarizationLoss_ref–PolarizationLoss_UE)}. Among them, AnteGain_ref is the terminal device antenna gain reference value, which can be a predefined value or a value configured by the network device. AnteGain_UE is the actual antenna gain of the terminal device. PolarizationLoss_ref is the polarization loss reference value of the terminal device. This value can be a predefined value or a value configured by the network device. PolarizationLoss_UE is the actual polarization loss of the terminal device.

In some embodiments, the first terminal device may also determine the third offset value based on polarization loss and/or antenna gain, combined with a compensation value configured by the network device. For example, the third offset value=max{0, AnteGain_ref–(AnteGain_UE-offset)}. Among them, offset is the compensation value configured by the network device. The network device may notify the first terminal device of the compensation value offset by broadcasting. In some embodiments, the first configuration information above may include the compensation value.

It should be noted that different third offset values may correspond to different mobility management operations. The first terminal device may determine a third offset value corresponding to each mobility management operation for different mobility management operations.

In some embodiments, the second condition corresponding to the first terminal device may include a relationship between the adjustment value of the signal measurement result and the signal measurement threshold. For example, the second condition may include that the adjustment value of the signal measurement result is greater than the signal measurement threshold. For another example, the second condition may include that the adjustment value of the signal measurement result is less than the signal measurement threshold. In some embodiments, the second condition corresponding to the first terminal device includes the relationship between the adjustment value of the signal measurement result and the signal measurement threshold, and the second condition corresponding to the second terminal device includes the relationship between the signal measurement result and the signal measurement threshold. corresponding relationship. That is to say, the first terminal device can perform mobility management operations based on the adjustment value of the signal measurement result and the first signal measurement threshold, and the second terminal device can perform mobility management based on the signal measurement result and the second signal measurement threshold. operate. In some embodiments, the first signal measurement threshold and the second signal measurement threshold may be equal.

In some embodiments, the adjustment value of the signal measurement result may be determined based on the signal measurement result and the fourth offset value. For example, the adjustment value of the signal measurement result=the signal measurement result+the fourth offset value, or the adjustment value of the signal measurement result=the signal measurement result-the fourth offset value. The fourth offset value may be greater than 0 or less than 0, and the size of the fourth offset value may be designed according to the actual situation.

In some embodiments, the network device may send indication information to the first terminal device to indicate whether the first terminal device needs to add a fourth offset value when determining the signal measurement result. If the indication information indicates that a fourth offset value needs to be added, the first terminal device determines the adjustment value of the signal measurement result according to the signal measurement result and the fourth offset value. If the indication information indicates that there is no need to add the fourth offset value, the first terminal device does not need to determine the adjustment value of the signal measurement result, but can directly use the signal measurement result. The indication information may be indication information indicating whether the cell supports coverage enhancement. If the cell supports coverage enhancement, the first terminal device may determine the adjustment value of the signal measurement result based on the signal measurement result and the sixth offset value. If the cell does not support coverage enhancement, the first terminal device directly uses the signal measurement result.

The fourth offset value may be an offset value configured by the network device, or may be an offset value predefined in the protocol, or may be an offset value calculated by the first terminal device. For example, the network device may send the fourth offset value to the first terminal device in a broadcast manner.

If the fourth offset value is an offset value configured by the network device, the network device may configure one offset value for the first terminal device, or may configure multiple offset values. That is to say, the above first configuration information may include one offset value or may include multiple offset values. The network device may send the offset value to the first terminal device in a broadcast manner. If the network device configures an offset value for the first terminal device, all first terminal devices use the same fourth offset value. If the network device configures multiple offset values for the first terminal device, the first terminal device may determine a fourth offset value from the multiple offset values according to the antenna gain and/or polarization loss.

If the fourth offset value is a predefined offset value in the protocol, one offset value or multiple offset values may be predefined for the first terminal device in the protocol. If an offset value is predefined for the first terminal device in the protocol, all first terminal devices use the same fourth offset value. If multiple offset values are predefined for the first terminal device in the protocol, the first terminal device may determine the fourth offset value from the multiple offset values according to the antenna gain and/or polarization loss.

The plurality of offset values described above may be associated with different antenna gains and/or polarization losses. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, so that the first terminal device is mapped to multiple levels, and each level corresponds to an offset value. The first terminal device may select a fourth offset value corresponding to its own antenna gain and/or polarization loss from a plurality of offset values according to its own antenna gain and/or polarization loss.

In some embodiments, the fourth offset value may be determined based on the fourth information. The fourth information includes one or more of the following information: the antenna gain of the first terminal device, the polarization loss of the first terminal device, and the compensation value of the network device configuration.

In some embodiments, the fourth information may include one or more of the following information: the difference between the antenna gain of the first terminal device and the antenna gain reference value, the polarization loss and polarization of the first terminal device. The difference between the loss reference values and the compensation value configured by the network device.

For example, the fourth offset value=max{0, AnteGain_ref-AnteGain_UE}. For another example, the fourth offset value={0, PolarizationLoss_ref–PolarizationLoss_UE}. For another example, the fourth offset value=max{0,AnteGain_ref–AnteGain_UE}+max{0,PolarizationLoss_ref–PolarizationLoss_UE}. For another example, the fourth offset value=max{0,(AnteGain_ref–AnteGain_UE)+(PolarizationLoss_ref–PolarizationLoss_UE)}. Among them, AnteGain_ref is the terminal device antenna gain reference value, which can be a predefined value or a value configured by the network device. AnteGain_UE is the actual antenna gain of the terminal device. PolarizationLoss_ref is the polarization loss reference value of the terminal device. This value can be a predefined value or a value configured by the network device. PolarizationLoss_UE is the actual polarization loss of the terminal device.

In some embodiments, the first terminal device may also determine the fourth offset value based on polarization loss and/or antenna gain, in combination with a compensation value configured by the network device. For example, the fourth offset value=max{0, AnteGain_ref–(AnteGain_UE-offset)}. Among them, offset is the compensation value configured by the network device. The network device may notify the first terminal device of the compensation value offset by broadcasting. In some embodiments, the first configuration information above may include the compensation value.

It should be noted that different fourth offset values may correspond to different mobility management operations. The first terminal device may determine a fourth offset value corresponding to each mobility management operation for different mobility management operations.

In this embodiment of the present application, the terminal device can determine the second condition for use according to its type. For example, the terminal device can determine the signal measurement threshold to use based on its type. If the type of the terminal device is a first terminal device type, the terminal device may use the first signal measurement threshold. If the type of the terminal device is a second terminal device type, the terminal device may use the second signal measurement threshold. For another example, the terminal device can determine whether to use the adjustment value of the signal measurement result according to its type. If the type of the terminal device is the first terminal device type, the terminal device may use the adjustment value of the signal measurement result. If the type of the terminal device is the second terminal device type, the terminal device can directly use the signal measurement result.

In this embodiment of the present application, regardless of whether the cell supports coverage enhancement (the cell only performs coverage enhancement for the first terminal device), the coverage range supported by the second terminal device remains unchanged. Therefore, the network device can be the second terminal device. Configure a second signal measurement threshold, which can save network device configuration overhead.

As can be seen from the above description, the signal measurement result may be Srxlev and/or Squal. In order to distinguish the second condition corresponding to the first terminal device from the second condition corresponding to the second terminal device, the first terminal device and the second terminal device may use different calculation methods to calculate Srxlev and/or Squal.

It can be seen from the above formula (1) and formula (2) that Srxlev can be determined based on Qrxlevmin, and Squal can be determined based on Qrxlevmin. Therefore, in some embodiments, the Qrxlevmin corresponding to the first terminal device is different from the Qrxlevmin corresponding to the second terminal device, and/or the Qqualmin corresponding to the first terminal device is different from the Qqualmin corresponding to the second terminal device.

The formula for calculating Srxlev and Squal by the first terminal device can be as follows:

Srxlev＝Qrxlevmeas–(Qrxlevmin_type1+Qrxlevminoffset)–Pcompensation-Qoffsettemp

Squal＝Qqualmeas–(Qqualmin_type1+Qqualminoffset)–Qoffsettemp

The formula for calculating Srxlev and Squal by the second terminal device can be as follows:

Srxlev＝Qrxlevmeas–(Qrxlevmin_type2+Qrxlevminoffset)–Pcompensation-Qoffsettemp

Squal＝Qqualmeas–(Qqualmin_type2+Qqualminoffset)–Qoffsettemp

Among them, Qrxlevmin_type1 is the lowest reception level value of the cell corresponding to the first terminal device, Qqualmin_type1 is the lowest reception quality value of the cell corresponding to the first terminal device, Qrxlevmin_type2 is the lowest reception level value of the cell corresponding to the second terminal device, and Qqualmin_type2 is the second The minimum reception quality value of the cell corresponding to the terminal device. The value of Qrxlevmin_type1 is different from the value of Qrxlevmin_type2, and the value of Qqualmin_type1 is different from the value of Qqualmin_type2.

Qrxlevmin_type1 can be one value or multiple values. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value size, thereby mapping the first terminal device to multiple levels, and each level corresponds to a Qrxlevmin_type1 value. If Qrxlevmin_type1 is a value, all first terminal devices use the same Qrxlevmin_type1 value when calculating Srxlev. If Qrxlevmin_type1 includes multiple values, the first terminal device may determine the Qrxlevmin_type1 value according to its own antenna gain and/or polarization loss.

Qqualmin_type1 can be one value or multiple values. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, thereby mapping the first terminal device to multiple levels, and each level corresponds to a Qqualmin_type1 value. If Qqualmin_type1 is a value, all first terminal devices use the same Qqualmin_type1 value when calculating Squal. If Qqualmin_type1 includes multiple values, the first terminal device may determine the Qqualmin_type1 value according to its own antenna gain and/or polarization loss.

The above Qrxlevmin_type1 and/or Qqualmin_type1 can be configured by the network device. The network device may notify the first terminal device of Qrxlevmin_type1 and/or Qqualmin_type1 by broadcasting. Alternatively, the above Qrxlevmin_type1 and/or Qqualmin_type1 may be predefined values in the protocol.

In some embodiments, the first terminal device may introduce the above-mentioned fourth offset value into the formula for calculating Srxlev and/or Squal. The second terminal device can still use the above formula (1) and formula (2) to calculate Srxlev and/or Squal.

For example, the formula for calculating Srxlev and Squal by the first terminal device can be as follows:

Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset+Qrxlevminoffset_type2)–Pcompensation-Qoffsettemp

Squal＝Qqualmeas–(Qqualmin+Qqualminoffset+Qqualminoffset_type2)-Qoffsettemp

Among them, Qrxlevminoffset_type2 and Qqualminoffset_type2 can be the fourth offset value introduced above.

For another example, the formula for calculating Srxlev and Squal by the first terminal device can be as follows:

Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation-Qoffsettemp- Qrxlevoffset_type2

Squal＝Qqualmeas–(Qqualmin+Qqualminoffset)-Qoffsettemp-Qqualoffset_type2

Among them, Qrxlevoffset_type2 and/or Qqualoffset_type2 may be the fourth offset value introduced above.

The above describes the difference between the first condition and/or the second condition used by the first terminal device and the second terminal device during the mobility management operation. The random access process is introduced below.

random access

During the random access process, the terminal device also needs to perform random access based on signal measurement results (such as RSRP value).

In some embodiments, the terminal device may select an SSB whose RSRP value is higher than the RSRP threshold (such as rsrp-ThresholdSSB) in the four-step random access process based on the RSRP measurement result.

In some embodiments, the terminal device can select an SSB with an RSRP value higher than the RSRP threshold (such as msgA-RSRP-ThresholdSSB) in a two-step random access process based on the RSRP measurement result.

In some embodiments, the terminal device may select a CSI-RS whose RSRP value is higher than the RSRP threshold (such as rsrp-ThresholdCSI-RS) based on the RSRP measurement result. The random access in this process can be four-step random access.

In some embodiments, the terminal device may select an uplink carrier based on the RSRP measurement results. Uplink carriers may include normal uplink (NUL) carriers and supplementary uplink (SUL) carriers. The terminal device can choose between NUL carrier and SUL carrier based on RSRP measurement results. For example, if the RSRP measurement value is greater than the RSRP threshold, the terminal device can use a NUL carrier. If the RSRP measurement value is less than or equal to the RSRP threshold, the terminal device can use the SUL carrier.

In some embodiments, the terminal device may select a random access type based on the RSRP measurement value and the RSRP threshold (such as msgA-RSRP-Threshold). For example, if the RSRP measurement value is greater than the RSRP threshold, the terminal device can select two-step random access. If the RSRP measurement value is less than the RSRP threshold, the terminal device selects four-step random access.

In some embodiments, the terminal device may determine whether to request repeated transmission of MSG3 based on the RSRP measurement value and the RSRP threshold (such as rsrp-ThresholdMsg3). If the RSRP measurement value is less than or equal to the RSRP threshold, the terminal device can request repeated transmission of MSG3. If the RSRP measurement value is greater than the RSRP threshold, the terminal device may not request repeated transmission of MSG3.

In some embodiments, the terminal device may determine whether to perform small data transmission (SDT) based on the RSRP measurement value and the RSRP threshold (such as sdt-RSRP-Threshold). If the RSRP measurement value is greater than the RSRP threshold, the terminal device can perform SDT. If the RSRP measurement value is less than the RSRP threshold, the terminal device does not perform SDT.

In some embodiments, the terminal device can perform configured grant SDT (configured grant SDT, CG-SDT) SSB selection based on the RSRP measurement value and the RSRP threshold (such as cg-SDT-RSRP-ThresholdSSB). The terminal device can select an SSB whose RSRP measurement value is greater than the RSRP threshold.

As can be seen from the above, the terminal device needs to use signal measurement conditions during the random access process. For a first terminal device and a second terminal device with different antenna processing capabilities, if the first terminal device and the second terminal device use the same signal measurement conditions to perform random access, the random access performance of the terminal device may deteriorate. It should be noted that the signal measurement condition may be the second condition described above. The first terminal device and the second terminal device may be the first terminal device and the second terminal device introduced in the previous embodiment.

For example, if the cell supports coverage enhancement, that is, the cell performs coverage enhancement for the first terminal device, then the coverage ranges actually supported by the first terminal device and the second terminal device should be the same. If the first terminal device and the second terminal device perform random access according to the same signal measurement conditions (such as the same RSRP threshold), since the antenna processing capability of the first terminal device is lower than the antenna processing capability of the second terminal device, it will cause The random access performance of the first terminal device becomes worse. For example, the number of random access parameters that the first terminal device can select becomes fewer, or the probability that the first terminal device selects two-step random access becomes lower.

Based on this, embodiments of the present application provide a wireless communication method. By setting signal measurement conditions associated with the antenna processing capabilities of the terminal device, the signal measurement conditions can be matched with the cell coverage actually supported by the terminal device, so that the signal measurement conditions can be matched with the cell coverage actually supported by the terminal device. Improve the random access performance of terminal equipment.

The wireless communication method according to the embodiment of the present application will be introduced below with reference to FIG. 8 and FIG. 9 .

Referring to Figure 8, in step S810, the first terminal device performs random access based on signal measurement conditions.

Referring to Figure 9, in step S910, the network device sends second configuration information to the first terminal device. This second configuration information may be used to determine signal measurement conditions. That is to say, the first terminal device can determine the signal measurement conditions based on the second configuration information.

It should be noted that the content described below is applicable to the solutions shown in Figures 8 and 9.

In some embodiments, the signal measurement condition may include a relationship between a signal measurement result and a signal measurement threshold. In other embodiments, the signal measurement condition may include the relationship between the adjustment value of the signal measurement result and the signal measurement threshold. The signal measurement conditions may include, for example, one or more of the following: the signal measurement result is greater than or equal to the signal measurement threshold, the signal measurement result is less than the signal measurement threshold, the adjustment value of the signal measurement result is greater than or equal to the signal measurement threshold, the signal measurement result is The adjustment value is less than the signal measurement threshold.

For different random access operations, the corresponding signal measurement thresholds may be the same or different, and this is not specifically limited in the embodiments of this application. For example, the signal measurement threshold used for SSB selection and the signal measurement threshold used for CSI-RS selection may be the same or different. For another example, the signal measurement threshold used for random access type selection and the signal measurement threshold used for SSB selection may be the same or different.

Signal measurement results may include one or more of the following: RSRP, RSRQ. If the signal measurement result is RSRP, the signal measurement threshold is the RSRP threshold. If the signal measurement result is RSRQ, the signal measurement threshold is the RSRQ threshold.

The signal measurement conditions in the embodiment of the present application are associated with the antenna processing capability of the first terminal device. If the antenna processing capabilities of the first terminal device and the second terminal device are different, the signal measurement conditions corresponding to the first terminal device and the signal measurement conditions corresponding to the second terminal device may be different or the same. For example, in a scenario where the serving cell does not support coverage enhancement, the signal measurement conditions corresponding to the first terminal device and the signal measurement conditions corresponding to the second terminal device may be the same. For another example, if the serving cell supports coverage enhancement, that is, the serving cell introduces coverage enhancement technology for the first terminal device, then the coverage range supported by the first terminal device and the second terminal device is the same, but because the first terminal device and the second terminal device The antenna processing capabilities of the devices are different. At the same location, the RSRP value measured by the first terminal device is lower than the RSRP value measured by the second terminal device. Therefore, in this case, the signal measurement conditions corresponding to the first terminal device are different from those of the second terminal device. The signal measurement conditions corresponding to the terminal equipment may be different, so that the first terminal equipment and the second terminal equipment can more accurately perform relevant decisions on the random access operation.

The first terminal device and the second terminal device in the embodiment of the present application may be similar to the first terminal device and the second terminal device mentioned above. For relevant content, please refer to the above description. To avoid redundancy, they will not be described again here.

In some embodiments, the signal measurement condition may include a relationship between a signal measurement result of the terminal device and a signal measurement threshold. If the antenna processing capabilities of the first terminal device and the second terminal device are different, the third signal measurement threshold of the first terminal device and the fourth signal measurement threshold of the second terminal device may be different. By setting different signal measurement thresholds, the first terminal device and the second terminal device can make more accurate decisions related to random access operations. If the antenna processing capability of the first terminal device is lower than the antenna processing capability of the second terminal device, the third signal measurement threshold may be lower than the fourth signal measurement threshold.

The fourth signal measurement threshold may be a threshold configured by the network device. For example, the network device may send the fourth signal measurement threshold to the terminal device (including the first terminal device and the second terminal device) in a broadcast manner. For different random access operations, different fourth signal measurement thresholds may be corresponding. For example, the SSB selection may correspond to a fourth signal measurement threshold. For another example, the CSI-RS selection may correspond to a fourth signal measurement threshold. For another example, the selection of the random access type may correspond to a fourth signal measurement threshold. For another example, the selection of NUL carrier and SUL carrier may correspond to a fourth signal measurement threshold.

The third signal measurement threshold may be a threshold configured by the network device, or the third signal measurement threshold may be a threshold predefined in the protocol, or the third signal measurement threshold may be a threshold calculated by the first terminal device.

Different random access operations may correspond to different third signal measurement thresholds. For example, the SSB selection may correspond to a third signal measurement threshold. For another example, the CSI-RS selection may correspond to a third signal measurement threshold. For another example, the selection of the random access type may correspond to a third signal measurement threshold. For another example, the selection of NUL carrier and SUL carrier may correspond to a third signal measurement threshold.

If the third signal measurement threshold is a threshold configured by the network device, the network device may configure one signal measurement threshold for the first terminal device, or may configure multiple signal measurement thresholds. That is to say, the above second configuration information may include one signal measurement threshold, or may include multiple signal measurement thresholds. The network device may send the signal measurement threshold to the first terminal device in a broadcast manner. If the network device configures a signal measurement threshold for the first terminal device, all first terminal devices use the same third signal measurement threshold. If the network device configures multiple signal measurement thresholds for the first terminal device, the first terminal device may determine a third signal measurement threshold from the multiple signal measurement thresholds based on the antenna gain and/or polarization loss.

If the third signal measurement threshold is a predefined threshold in the protocol, one signal measurement threshold may be predefined for the first terminal device in the protocol, or multiple signal measurement thresholds may be predefined. If a signal measurement threshold is predefined for the first terminal device in the protocol, all first terminal devices use the same third signal measurement threshold. If multiple signal measurement thresholds are predefined for the first terminal device in the protocol, the first terminal device may determine the third signal measurement threshold from the multiple signal measurement thresholds based on the antenna gain and/or polarization loss.

In some embodiments, the third signal measurement threshold may be determined based on the fourth signal measurement threshold. That is to say, the first terminal device may determine the third signal measurement threshold based on the fourth signal measurement threshold. The embodiment of the present application does not specifically limit the calculation method of the third signal measurement threshold. For example, the third signal measurement threshold may be determined based on the fourth signal measurement threshold and the fifth offset value. That is to say, the first terminal device can determine the third signal measurement threshold according to the fourth signal measurement threshold and the fifth offset value. In some embodiments, the third signal measurement threshold=the fourth signal measurement threshold+the fifth offset value, or the third signal measurement threshold=the fourth signal measurement threshold-the fifth offset value. The fifth offset value can be greater than 0 or less than 0, and the size of the fifth offset value can be designed according to the actual situation.

If the third signal measurement threshold is determined based on the fourth signal measurement threshold, the network device may send indication information to the first terminal device to indicate whether the first terminal device needs to add a fifth offset when determining the third signal measurement threshold. value. If the indication information indicates that a fifth offset value needs to be added, the first terminal device determines the third signal measurement threshold based on the fourth signal measurement threshold and the fifth offset value. If the indication information indicates that there is no need to add the fifth offset value, the first terminal device may use the fourth signal measurement threshold as the third signal measurement threshold. The indication information may be indication information indicating whether the cell supports coverage enhancement. If the cell supports coverage enhancement, the third signal measurement threshold may be determined based on the third signal measurement threshold and the fifth offset value. If the cell does not support coverage enhancement, the third signal measurement threshold is equal to the fourth signal measurement threshold.

The fifth offset value may be an offset value configured by the network device, or may be a predefined offset value in the protocol, or may be an offset value calculated by the first terminal device. For example, the network device may send the fifth offset value to the first terminal device in a broadcast manner.

If the fifth offset value is an offset value configured by the network device, the network device may configure one offset value for the first terminal device, or may configure multiple offset values. That is to say, the above second configuration information may include one offset value or multiple offset values. The network device may send the offset value to the first terminal device in a broadcast manner. If the network device configures an offset value for the first terminal device, all first terminal devices use the same fifth offset value. If the network device configures multiple offset values for the first terminal device, the first terminal device may determine the fifth offset value from the multiple offset values according to the antenna gain and/or polarization loss.

If the fifth offset value is a predefined offset value in the protocol, one offset value or multiple offset values may be predefined for the first terminal device in the protocol. If an offset value is predefined for the first terminal device in the protocol, all first terminal devices use the same fifth offset value. If multiple offset values are predefined for the first terminal device in the protocol, the first terminal device may determine the fifth offset value from the multiple offset values according to the antenna gain and/or polarization loss.

The plurality of offset values described above may be associated with different antenna gains and/or polarization losses. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, so that the first terminal device is mapped to multiple levels, and each level corresponds to an offset value. The first terminal device may select a fifth offset value corresponding to its own antenna gain and/or polarization loss from a plurality of offset values according to its own antenna gain and/or polarization loss.

In some embodiments, the fifth offset value may be determined based on fifth information. The fifth information includes one or more of the following information: the antenna gain of the first terminal device, the polarization loss of the first terminal device, and the compensation value of the network device configuration.

In some embodiments, the fifth information may include one or more of the following information: the difference between the antenna gain of the first terminal device and the antenna gain reference value, the polarization loss and polarization of the first terminal device. The difference between the loss reference values and the compensation value configured by the network device.

For example, the fifth offset value=max{0, AnteGain_ref-AnteGain_UE}. For another example, the fifth offset value={0, PolarizationLoss_ref–PolarizationLoss_UE}. For another example, the fifth offset value=max{0,AnteGain_ref–AnteGain_UE}+max{0,PolarizationLoss_ref–PolarizationLoss_UE}. For another example, the fifth offset value=max{0,(AnteGain_ref–AnteGain_UE)+(PolarizationLoss_ref–PolarizationLoss_UE)}. Among them, AnteGain_ref is the terminal device antenna gain reference value, which can be a predefined value or a value configured by the network device. AnteGain_UE is the actual antenna gain of the terminal device. PolarizationLoss_ref is the polarization loss reference value of the terminal device. This value can be a predefined value or a value configured by the network device. PolarizationLoss_UE is the actual polarization loss of the terminal device.

In some embodiments, the first terminal device may also determine the fifth offset value based on polarization loss and/or antenna gain, combined with a compensation value configured by the network device. For example, the fifth offset value=max{0, AnteGain_ref–(AnteGain_UE-offset)}. Among them, offset is the compensation value configured by the network device. The network device may notify the first terminal device of the compensation value offset by broadcasting. In some embodiments, the second configuration information above may include the compensation value.

It should be noted that different fifth offset values may correspond to different random access operations. The first terminal device may determine the fifth offset value corresponding to each random access operation for different random access operations.

In some embodiments, the signal measurement conditions corresponding to the first terminal device may include the relationship between the adjustment value of the signal measurement result and the signal measurement threshold. For example, the signal measurement condition may include that the adjustment value of the signal measurement result is greater than the signal measurement threshold. For another example, the signal measurement condition may include that the adjustment value of the signal measurement result is less than the signal measurement threshold. In some embodiments, the signal measurement conditions corresponding to the first terminal device include the relationship between the adjustment value of the signal measurement result and the signal measurement threshold, and the signal measurement conditions corresponding to the second terminal device include the relationship between the signal measurement result and the signal measurement threshold. corresponding relationship. That is to say, the first terminal device can perform a random access operation based on the adjustment value of the signal measurement result and the third signal measurement threshold, and the second terminal device can perform a random access operation based on the signal measurement result and the fourth signal measurement threshold. operate. In some embodiments, the third signal measurement threshold and the fourth signal measurement threshold may be equal.

In some embodiments, the adjustment value of the signal measurement result may be determined based on the signal measurement result and the sixth offset value. For example, the adjustment value of the signal measurement result = the signal measurement result + the sixth offset value, or the adjustment value of the signal measurement result = the signal measurement result - the sixth offset value. The sixth offset value may be greater than 0 or less than 0, and the size of the sixth offset value may be designed according to the actual situation.

In some embodiments, the network device may send indication information to the first terminal device to indicate whether the first terminal device needs to add a sixth offset value when determining the signal measurement result. If the indication information indicates that a sixth offset value needs to be added, the first terminal device determines the adjustment value of the signal measurement result according to the signal measurement result and the sixth offset value. If the indication information indicates that it is not necessary to add the sixth offset value, the first terminal device may not need to determine the adjustment value of the signal measurement result, but may directly use the signal measurement result. The indication information may be indication information indicating whether the cell supports coverage enhancement. If the cell supports coverage enhancement, the first terminal device may determine the adjustment value of the signal measurement result based on the signal measurement result and the sixth offset value. If the cell does not support coverage enhancement, the first terminal device directly uses the signal measurement result.

The sixth offset value may be an offset value configured by the network device, or may be a predefined offset value in the protocol, or may be an offset value calculated by the first terminal device. For example, the network device may send the sixth offset value to the first terminal device in a broadcast manner.

If the sixth offset value is an offset value configured by the network device, the network device may configure one offset value for the first terminal device, or may configure multiple offset values. That is to say, the above second configuration information may include one offset value or may include multiple offset values. The network device may send the offset value to the first terminal device in a broadcast manner. If the network device configures an offset value for the first terminal device, all first terminal devices use the same sixth offset value. If the network device configures multiple offset values for the first terminal device, the first terminal device may determine a sixth offset value from the multiple offset values according to the antenna gain and/or polarization loss.

If the sixth offset value is a predefined offset value in the protocol, one offset value or multiple offset values may be predefined for the first terminal device in the protocol. If an offset value is predefined for the first terminal device in the protocol, all first terminal devices use the same sixth offset value. If multiple offset values are predefined for the first terminal device in the protocol, the first terminal device may determine the sixth offset value from the multiple offset values according to the antenna gain and/or polarization loss.

The plurality of offset values described above may be associated with different antenna gains and/or polarization losses. In some embodiments, the antenna gain and/or polarization loss can be divided into multiple intervals according to the value, so that the first terminal device is mapped to multiple levels, and each level corresponds to an offset value. The first terminal device may select a sixth offset value corresponding to its own antenna gain and/or polarization loss from a plurality of offset values according to its own antenna gain and/or polarization loss.

In some embodiments, the sixth offset value may be determined based on sixth information. The sixth information includes one or more of the following information: the antenna gain of the first terminal device, the polarization loss of the first terminal device, and the compensation value of the network device configuration.

In some embodiments, the sixth information may include one or more of the following information: the difference between the antenna gain of the first terminal device and the antenna gain reference value, the polarization loss and polarization of the first terminal device. The difference between the loss reference values and the compensation value configured by the network device.

For example, the sixth offset value=max{0, AnteGain_ref-AnteGain_UE}. For another example, the sixth offset value={0, PolarizationLoss_ref–PolarizationLoss_UE}. For another example, the sixth offset value=max{0,AnteGain_ref–AnteGain_UE}+max{0,PolarizationLoss_ref–PolarizationLoss_UE}. For another example, the sixth offset value=max{0,(AnteGain_ref–AnteGain_UE)+(PolarizationLoss_ref–PolarizationLoss_UE)}. Among them, AnteGain_ref is the terminal device antenna gain reference value, which can be a predefined value or a value configured by the network device. AnteGain_UE is the actual antenna gain of the terminal device. PolarizationLoss_ref is the polarization loss reference value of the terminal device. This value can be a predefined value or a value configured by the network device. PolarizationLoss_UE is the actual polarization loss of the terminal device.

In some embodiments, the first terminal device may also determine the sixth offset value based on polarization loss and/or antenna gain, combined with a compensation value configured by the network device. For example, the sixth offset value=max{0, AnteGain_ref–(AnteGain_UE-offset)}. Among them, offset is the compensation value configured by the network device. The network device may notify the first terminal device of the compensation value offset by broadcasting. In some embodiments, the second configuration information above may include the compensation value.

It should be noted that different sixth offset values may correspond to different random access operations. The first terminal device may determine a sixth offset value corresponding to each random access operation for different random access operations.

In the embodiment of the present application, the terminal device can determine the signal measurement conditions to be used according to its own type. For example, the terminal device can determine the signal measurement threshold to use based on its type. If the type of the terminal device is the first terminal device type, the terminal device may use the third signal measurement threshold. If the type of the terminal device is the second terminal device type, the terminal device may use the fourth signal measurement threshold. For another example, the terminal device can determine whether to use the adjustment value of the signal measurement result according to its type. If the type of the terminal device is the first terminal device type, the terminal device may use the adjustment value of the signal measurement result. If the type of the terminal device is the second terminal device type, the terminal device can directly use the signal measurement result.

In this embodiment of the present application, regardless of whether the cell supports coverage enhancement (the cell only performs coverage enhancement for the first terminal device), the coverage range supported by the second terminal device remains unchanged. Therefore, the network device can be the second terminal device. Configure a fourth signal measurement threshold, which can save network device configuration overhead.
