Before the technical solutions of the present disclosure are introduced, some background knowledge related to the present disclosure will be described.
In a communication system, a terminal device needs to periodically measure downlink signals to keep track of network cells, and RRM measurement is a measurement mode for measuring downlink signals defined in a communication standard.
Based on the definition in TS 38.133, the conventional RRM measurement refers to: the terminal equipment performs measurement according to a fixed measurement interval. The measurement relaxation refers to a RRM measurement mode that achieves the purpose of reducing measurement power consumption by reducing the number of RRM measurements. In the related art, measuring relaxation generally refers to measuring relaxation in the time domain, such as: measurement is not performed during a period of time, or the measurement interval is increased to reduce the number of measurements, thereby reducing measurement power consumption.
1) R15 measurement relaxation scheme
The measurement rules for cell reselection defined in TS38.304 are as follows:
for on-frequency measurements:
if the serving cell satisfies S rxlev >S IntraSearchP And S qual >S IntraSearchQ Then the terminal device may choose not to perform the same frequency measurement.
If the serving cell satisfies S rxlev ≤S IntraSearchP Or S qual ≤S IntraSearchQ And the terminal equipment should perform the same-frequency measurement.
For inter-frequency or inter-system measurements:
if the serving cell satisfies S rxLev >S nonIntraSearchP And, S qual >S nonIntraSearchQ The terminal equipment can choose not to execute the measurement of NR pilot frequency or inter-system cell with the same priority or lower priorityAn amount; the terminal device should measure the NR pilot frequency with higher priority or the inter-system layer by at least K × 60s, where K is the number of the pilot frequency and the inter-system layer.
If the serving cell satisfies S rxlev ≤S nonIntraSearchP And, S qual ≤S nonIntraSearchQ The terminal device should search for and measure the different frequency layers with higher, equal or lower priority to prepare for possible reselection.
The basic idea is that when the terminal device performs the inter/inter frequency measurement (equal priority or lower priority) of the neighboring cell, if the Reference Signal Receiving Power (RSRP)/Reference Signal Receiving Quality (RSRQ) of the serving cell is higher than the threshold (S) IntraSearchP ，S IntraSearchQ ) In this case, the co-frequency measurement may not be performed, or the co-frequency/inter-frequency measurement of the same class or less may not be performed. For the high priority pilot frequency measurement of the adjacent cell, if the RSRP/RSRQ of the service cell is higher than the threshold (S) IntraSearchP ，S IntraSearchQ ) In time, measurement relaxation to 60s is performed.
2) R16 measurement relaxation protocol
A measurement relaxation protocol, comprising two parts: one part is the judgment of the measurement relaxation standard, that is, what standard the terminal needs to meet is to measure the relaxation, the rule is that the terminal is configured with a certain measurement threshold through the network, and the terminal judges according to the rule and the threshold to determine whether the relaxation can be carried out; another part is the measurement relaxation criteria, i.e. after different relaxation conditions are reached, and in particular how to perform what kind of relaxation, is decided based on the measurement relaxation criteria provided by the RAN 4.
2.1 relaxation rules
There are currently two relaxation rules, one of which is low mobility; one relaxation rule is not at the cell edge.
2.11 Low mobility
Within a certain time (T) SearchDeltaP ) If the reference received signal quality and the current RSRP of the terminal equipment are the sameThe difference is less than a preset threshold value (S) SearchDeltaP ) I.e., the representative signal does not vary much in magnitude, it may be considered to be currently in a stationary or low mobility state. It is noted that the decision needs to be considered only when the signal is falling, and the specific decision conditions are as follows:
(S rxlevRef –S rxlev )<S SearchDeltaP
wherein S is rxlev = S of current serving cell rxlev In dB; s rxlevRef = S of current serving cell rxlev Reference value in dB.
S rxlevRef The setting is performed according to the following manner:
(1) The UE selects or reselects a new cell.
(2)(S rxlev -S rxlevRef >0)。
(3) At T SearchDeltaP The decision condition is not satisfied.
When any one of the above conditions is met, the terminal device will S rxlevRef S set as current serving cell rxlev 。
With respect to T SearchDeltaP Setting of (2), LTE System setting T SearchDeltaP Is 5mins; NR is set to this value is configurable, the case currently under discussion being: t is SearchDeltaP The time should be set to 5 minutes or less and satisfy a multiple relation of the measurement period. If eDRX is configured, if the eDRX period is more than 5 minutes, then T is set SearchDeltaP Set to eDRX cycle.
In LTE, the terminal device needs to perform measurements every 24 hours, even if the relaxation condition is satisfied. In NR, R16 is defined as measuring relaxation or stopping measurement (see the relaxation criteria section below).
2.12 cell edge
If the terminal equipment is at the current S rxlev Is greater than a threshold value S searchThresholdP And S qual Greater than a threshold value S searchThresholdQ (if configured), the terminal device is considered not to be located at the cell edge, and the specific determination conditions are as follows:
S rxlev >S searchThresholdP and, S qual >S searchThresholdQ (if configured)
Wherein S is rxlev = S of current serving cell rxlev In dB; s qual = S of current serving cell qual In dB.
It can be understood that these two thresholds are more relaxed thresholds than the stop measurement in R15, and as shown in fig. 2, the defined non-at-cell edge in R16 corresponds to the middle portion region 210 in fig. 1.
2.2 measuring relaxation patterns
Mode 1. Relax the measurement period defined in R15 to a wider time measurement interval.
Mode 2.
Mode 3, when the pilot frequency measurement with high priority level is carried out, if the RSRP/RSRQ of the service cell is higher than the threshold, the measurement is relaxed to K x 60s.
It will be appreciated that no measurement relaxation is performed, i.e. normal RRM measurements are performed as defined in the existing TS 38.133.
The final relaxation results measured in R16 are as follows:
based on the original R15, for the additional requirement of the relaxation condition, for example, for the non-central user with the same frequency/low priority, if the requirement of not being at the cell edge or low mobility is met, the further relaxation measurement is performed, that is, the measurement period defined in R15 is relaxed to a wider time measurement interval by using the criterion 1.
The disclosed embodiments do not preclude the introduction of a new measurement relaxation mode in R17.
3) Redcap user
In the current 3GPP standardization, a new terminal type called a limited capability terminal (Reduced capability UE), or simply NR-lite or Redcap terminal, is proposed. Similar to the internet of things device in LTE, the device generally needs to meet the following requirements: low cost and complexity; coverage enhancement to a certain extent; power is saved.
After the introduction of the Redcap user, unlike a general Enhanced Mobile Broadband (eMBB) user, the Redcap user is stationary in a partial scene, so the mobility is much lower than that of the eMBB user. A general idea at present is to introduce a new decision threshold for the Redcap user, that is, to decide the characteristics of the Redcap user as static (static) according to a more strict mobility criterion.
The measurement relaxation mechanism of R16 needs to take into account some enhancements to accommodate Redcap users. The approach widely discussed at present is to introduce a more stringent decision for the previous low mobility, probably for (S) rxlevRef –S rxlev )<S SearchDeltaP Setting a smaller S SearchDeltaP Using the smaller S SearchDeltaP To decide whether or not to be at rest for the Redcap user.
The current possible temporal relaxation modes may include:
temporal relaxation mode 1: i.e. not measured for a longer time than the original (1 hour) basis for stopping the measurement.
As an example of implementation: the measurement was stopped for X hours, X > =1.
Temporal relaxation mode 2: namely, the measurement interval is increased on the basis of the original measurement.
As an example of implementation: the relaxation measurement (scaling factor ') is performed using a longer measurement interval, wherein the scaling factor' is a larger scaling factor than the original scaling factor. The scaling factor adopted in the existing protocol is K1, i.e. a scaling factor larger than K1 is introduced.
4) Network slicing
A network slice may provide a complete end-to-end virtual network for a particular user. By dividing network resources into multiple network slices, a 5G network slice can provide differentiated services to users with different service requirements (e.g., delay, reliability, capacity, isolation, and other functions). The operator network can not only serve the information consumption service with Best Effort transmission as the communication demand characteristic, but also satisfy the production control service with certainty transmission as the communication demand characteristic, and allocate logically or physically isolated network resources for the service with different communication demands.
One Network slice consists of a Radio Access Network (RAN) part and a Core Network (CN) part. The implementation of network slicing depends on the principle that traffic of different slices is processed by different Protocol Data Unit (PDU) sessions. The network may implement different network slices by scheduling and providing different L1/L2 configurations.
Each Network Slice is uniquely identified by a Single Network Slice Selection Information (S-NSSAI), which consists of a Slice Service Type (Slice/Service Type, SST) and a Slice Differentiator (SD). NSSAI is a collection of S-NSSAIs, including one or more S-NSSAIs.
In a practical scenario, for a terminal device with a specific requirement, the network device does not need to start measurement relaxation for the terminal device, such as: for a terminal device with a positioning requirement, if the network device configures the terminal device to perform measurement relaxation by expanding the measurement interval, and the position of the terminal device may change greatly within the measurement interval, positioning is performed based on a measurement result corresponding to the larger measurement interval, which may cause inaccuracy of the positioning result. In the related art, the network device independently configures the measurement relaxation of the terminal device, and the network device cannot effectively acquire the related requirements of the terminal device or the network side.
In the embodiment of the present disclosure, the auxiliary information is sent to the base station through the network element device, so that the base station can determine the relevant configuration of the measurement relaxation of the terminal device in combination with the auxiliary information. This is exemplified by the following examples.
Fig. 3 is a flowchart illustrating a measurement relaxation method according to an exemplary embodiment of the present disclosure, which may be applied to the communication system shown in fig. 1. The method can comprise the following steps:

Wherein measurement relaxation refers to a measurement mode that reduces the number of measurements compared to conventional RRM measurements performed as defined in TS 38.133. The measurement relaxation is convenient for saving the energy consumption of the terminal equipment.

In another possible implementation manner, there is one network element device that sends the assistance information to the base station, where the assistance information is related to a plurality of network element devices.

In summary, in the method provided in this embodiment, the terminal device sends the second auxiliary information to the base station, so that the base station can determine the relevant configuration for the terminal device to perform measurement relaxation by combining with the second auxiliary information.
In an exemplary embodiment, the network element device includes a core network, and the core network belongs to a non-access stratum network element. Accordingly, the auxiliary information includes third auxiliary information.
