Detailed Description

The present invention will be described in further detail with reference to examples, and the related art will be described.

As described above, the reference symbols for RLM, BFD, CBD, L1-RSRP and L1-SINR in the prior art are configured independently of the network, and the UEs perform the corresponding procedures independently of each other. There are the following problems:

1. the reference symbols for different purposes may be repeatedly configured, but in the prior art, the reference symbols are independently configured, and thus, the signaling overhead is wasted;

2. RLM, BFD, CBD, L1-RSRP and L1-SINR are respectively and independently carried out by UE, and the terminal carries out respectively and independently measuring and monitoring processes aiming at different purposes, so that the power consumption of the terminal is wasted.

In the prior art, RLM, BFD, CBD, L1-RSRP and L1-SINR are respectively independent UE behaviors, and a terminal in the limit condition needs to respectively start RLM, BFD, CBD, L-RSRP and L1-SINR for 5 monitoring processes, so that the complexity is high and the power consumption is high.

In practice, the RLM, BFD, CBD, L1-RSRP and the L1-SINR are related to the link quality, and the independent UE processes can be integrated or coordinated, so that the terminal power consumption is reduced, and the system performance is improved.

Based on this, the present invention proposes a RLM, BFD, CBD, RSRP, SINR resource allocation and terminal behavior integration scheme, where the above RLM, BFD, CBD, RSRP, SINR monitoring is implemented by a single mechanism or fewer mechanisms, for example, the monitoring of RLM, BFD, CBD, RSRP, SINR is implemented by a process at the same time, so as to reduce complexity and reduce terminal power consumption.

The present invention will be described in further detail with reference to examples.

Fig. 1 is a schematic diagram of a communication method according to an embodiment of the present invention, as shown in fig. 1, where the method is applied to a terminal, such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a Personal Digital Assistant (PDA), a tablet personal computer (PAD), a Portable Multimedia Player (PMP), a wearable device (such as a smart bracelet, a smart watch, etc.), a navigation device, etc.; the method comprises the following steps:

Step 101, receiving first information; the first information comprises an index of a reference symbol and/or first indication information;

the first indication information is used for at least one of the following:

instruct execution of one or more of RLM, BFD, CBD;

In some embodiments, the index of the reference symbol represents an identification of the reference symbol, which may be described as a resource Identification (ID).

In some embodiments, one reference symbol may be associated for multiple purposes in RLM, BFD, CBD, RSRP, SINR. I.e. the measurement of the reference symbol can be used for a number of purposes. The first indication information is used to indicate which measurement or monitoring purpose a reference symbol corresponding to an index of a reference symbol can be used for.

In some embodiments, the first information includes an index of the reference symbol and/or first indication information, where the first indication information is used to indicate that one or more of RLM, BFD, CBD is performed, it may be understood that the first indication information indicates: the above-mentioned at least 2 operations are performed on the basis of the same, same group or same set of reference symbols.

Here, at least 2 purposes are accomplished based on the measurement results of the same, same group or same set of reference symbols. The main purpose of this operation is to achieve multiple requirements in RLM, BFD, CBD based on the same measurement mechanism or the same flow.

Unlike the RLM, BFD, CBD, L1-RSRP and the L1-SINR in the prior art, which are respectively and independently configured and independently measured, the waste of resources and power consumption exists. In the embodiment of the invention, the plurality of requirements in RLM, BFD, CBD are realized based on the same measurement mechanism or the same flow, so that the resources are saved and the power consumption waste is avoided.

In some embodiments, the first information includes an index of the reference symbol and/or first indication information, where the first indication information is used to indicate one or more of measurement RSRP, SINR, SS-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP, CSI-RSRQ, CSI-SINR, and it may be understood that measurement of the measurement amount in RSRP, SINR, SS-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP, CSI-RSRQ, CSI-SINR is completed based on the reference symbol in the first information, and the measurement result may be used in RLM, BFD, CBD.

In some embodiments, the receiving the first information includes: first information is received from a network device. I.e. the network device determines and transmits said first information, which is received by said terminal accordingly.

In some embodiments, the reference symbols include at least one of: a Synchronization Signal Block (SSB), a channel state information reference signal (CSI-RS).

In some embodiments, the number of reference symbols indicated by the first information is N; n is more than or equal to 1;

and M and N are integers.

In some embodiments, the first information comprises: the index of the reference symbol and the measurement purpose corresponding to the reference symbol.

In practice, different sets of measurements may be made based on the same resource ID reference symbol.

Based on this, in some embodiments, the method further comprises: based on the reference symbols, at least one of the following sets of measurements is made:

RLM、BFD、CBD；

RLM、BFD；

RLM、CBD；

RSRP、SINR；

RLM、BFD、CBD、RSRP、SINR。

that is, the above measurements of each group may be performed for the reference symbol of the same resource ID.

For example, for RLM, BFD, CBD, consider that both RLM and BFD are related to link monitoring, where RLM is the monitoring of the overall quality of the link, including synchronous monitoring, out-of-step monitoring; BFD is quality detection for beam level; and CBD is to find candidate beams for beam restoration.

In some embodiments, the RSRP comprises: layer 1 reference signal received power (L1-RSRP, layer 1-Reference Signal Received Power), layer 3 reference signal received power (L3-RSRP, layer 3-Reference Signal Received Power);

That is, the measured SINR may be L1-SINR or L3-SINR. The measured RSRP may be L1-RSRP or L3-RSRP.

In some embodiments, the method further comprises at least one of:

Here, the T1 duration, the T2 duration, the T3 duration, the T4 duration, and the T5 duration may include the scenes in 2. Scene 1: the duration corresponds to a measurement duration of 1 reference symbol; scene 2: the time period corresponds to a total time period for completing the measurement of the plurality of reference symbols.

Considering BFD as beam level monitoring and RLM as overall link monitoring, it is desirable that BFD and RLM can be triggered separately even if BFD and RLM are performed based on the same reference symbol of resource ID. In practical application, based on the consideration:

further, the first threshold is lower than the second threshold, i.e. compared to the step-out of RLM, the terminal can trigger beam failure more easily;

further, the duration of T1 is smaller than the duration of T2, i.e. compared with the loss of synchronization of RLM, the terminal can trigger beam failure more rapidly;

further, the number of resources for RLM is greater than the number of resources for BFD, i.e. N > M.

In addition, the step out includes a radio link step out. The step-out reporting by the terminal comprises the following steps: reporting the step-out indication to a high layer by a terminal physical layer; and when the out-of-step indication continuously reported by the physical layer is greater than or equal to a threshold, reporting the out-of-step to the network equipment by the terminal. The reporting may also be described as transmitting.

In particular, considering that CBD is beam level monitoring and RLM is overall link monitoring, it is desirable that CBD and RLM can be triggered separately even if CBD and RLM are performed based on the same reference symbol of resource ID. In practical application, based on the consideration:

further, the third threshold is higher than the fourth threshold/the fifth threshold, that is, compared with the synchronization of the RLM, the terminal can more easily report the candidate beam;

Further, the time length of T3 is longer than the time length of T4/time length of T5, that is, compared with the synchronization of RLM, the terminal can report the candidate wave beams more quickly;

further, the number of resources for RLM is greater than the number of resources for CBD.

In addition, the synchronization includes radio link synchronization. The terminal reporting synchronization comprises the following steps: the physical layer reports a synchronization instruction to a higher layer; when the synchronization instruction continuously reported by the physical layer is greater than or equal to a threshold, the terminal reports synchronization to the network equipment.

Specifically, the SINR and RSRP transmitted by the terminal include: and measuring results of the reference symbols with quality higher than the threshold. The transmission may also be described as reporting.

Specifically, the duration T1, the duration T2, the duration T3, the duration T4, and the duration T5 are determined based on the number of measured reference symbols and the reference symbol period.

In some embodiments, the method further comprises at least one of:

a reference symbol with the L1-SINR higher than or equal to a fifth quality threshold exists in the reference symbols detected in a fifth time window, and a fifth measurement result is obtained; the fifth measurement comprises at least one of: an index of a reference symbol corresponding to the L1-SINR above or equal to the fifth quality threshold, the L1-SINR above or equal to the fifth quality threshold.

In some embodiments, the method further comprises:

determining SINR and/or RSRP of the reference symbols;

Wherein the at least one offset value is transmitted by the network device or is predetermined based on a protocol.

The method further comprises the steps of: at least one offset value is obtained.

The obtaining at least one offset value, corresponding to a case where the at least one offset value is transmitted by the network device, includes: at least one offset value transmitted by the network device is received. Fig. 2 is a schematic flow chart of a communication method according to an embodiment of the present invention.

In practical application, the measurement result obtained by processing the measurement result for a certain purpose is considered, so that the method can be used for other purposes, reduces the measurement load of the terminal, avoids frequent measurement and reduces power consumption. RLM is an evaluation of the overall link quality and requires high measurement results. The measurement of BFD and CBD is the measurement of beam level, so the measurement results for BFD and CBD are combined with a certain quality offset value, and a more stable measurement result can be obtained for RLM.

Based on this, in some embodiments, the at least one offset value comprises: the first offset value, the second offset value, the third offset value, the fourth offset value, the fifth offset value.

The method further comprises at least one of:

SINR based on BFD and the first offset value can be used for RLM;

SINR based on CBD and second offset value SINR, can be used for RLM;

the CBD-based RSRP and the third offset value can be used for RLM;

based on the L1-RSRP and the fourth offset value, RSRP can be used for CBD;

SINR based on L1-SINR and a fifth offset value may be used for BFD.

Here, the SINR of BFD may be understood as: SINR measured for reference symbols for Beam Failure Detection (BFD); the SINR of the BFD may be used to determine if BFD occurs;

similarly, the SINR of the CBD can be understood as: SINR measured for reference symbols for Candidate Beam Detection (CBD); the SINR of the CBD may be used to determine whether a candidate beam is found;

the RSRP of the CBD can be understood as: RSRP for performing Candidate Beam Detection (CBD), the RSRP being measured for reference symbols; the RSRP of the CBD may be used to determine whether a candidate beam is found.

Here, the L3-RSRP may also be used for Candidate Beam Detection (CBD) based on the L1-RSRP and the RSRP obtained by the fourth offset value (the L3-RSRP where RSRP is a reference symbol is obtained);

Based on the L1-SINR and the SINR obtained by the fifth offset value (the L3-SINR with RSRP as a reference symbol is obtained), the L3-SINR can also be used for Beam Failure Detection (BFD).

The new SINR and RSRP are obtained based on SINR and RSRP of BFD and CBD and each offset value, and can be used for synchronization and desynchronization of RLM.

The value and the specific function of each offset value in the at least one offset value are preconfigured by the network device or the protocol based on the actual application, and are not specifically limited herein.

In practical application, in order to reduce the load of terminal measurement, avoid frequent measurement, and reduce power consumption, it is desirable to be able to perform other purposes based on the measurement results for some purposes. Thus, a threshold and offset value for BFD and CBD are processed to obtain a new threshold value; the new threshold value may be used for the synchronization and out-of-sync evaluation of RLM.

Based on this, in some embodiments, the method further comprises at least one of:

when the SINR of BFD is higher than or equal to a second new threshold, the terminal reports synchronization; the second new threshold is derived based on the threshold for BFD and a second offset value;

When the SINR of the CBD is higher than or equal to a third new threshold, the terminal reports synchronization; the third new threshold is derived based on the threshold for CBD and a third offset value;

when the SINR of the CBD is lower than or equal to a fourth new threshold, reporting the step out by the terminal; the fourth new threshold is derived based on the threshold for CBD and a fourth offset value;

The offset values (first offset value, second offset value, third offset value, fourth offset value, and fifth offset value) may be RSRP or SINR. The offset values have a plurality of values, and offset values with different values can be used for different scenes. The description is not intended to be limiting.

In some embodiments, the determining the measurement result according to the SINR and/or RSRP of the reference symbol, at least one offset value, and the corresponding target gate includes at least one of:

In some embodiments, the method further comprises at least one of:

Here, the SINR may be L1-SINR or L3-SINR. The RSRP may be L1-RSRP or L3-RSRP.

The terminal reporting synchronization includes: the terminal physical layer reports a synchronization instruction to a higher layer; when the synchronization instruction continuously reported by the physical layer is greater than or equal to a threshold, the terminal reports synchronization to the network equipment.

For example, the terminal makes an L1-RSRP measurement of a certain reference symbol in a T9 time. The terminal physical layer transmits to the higher layer a resource ID with an L1-RSRP higher than or equal to the ninth threshold, and/or an L1-RSRP.

And the terminal performs L1-SINR measurement of a certain reference symbol in T10 time, and when L1-RSRP is larger than a ninth threshold and L1-SINR is larger than a tenth threshold, the physical layer of the terminal reports the synchronization instruction to a higher layer.

In some embodiments, the method further comprises:

Here, reporting the step-out by the terminal includes: the terminal reports a wireless link step-out indication; the terminal reporting synchronization comprises the following steps: and the terminal reports the wireless link synchronization instruction.

For example, the terminal makes SINR measurements for W reference symbols (the measurement time for each reference symbol does not exceed the T11 duration). When the quality (e.g., SINR) of each of the V reference symbols is less than or equal to the eleventh threshold, the terminal physical layer reports a beam failure indication (BFD) to a higher layer.

At the same time, the terminal starts the first timer and the second timer, and the terminal performs SINR measurement of the U reference symbols (the measurement time for each reference symbol does not exceed the duration T12) and/or RSRP measurement of the I reference symbols (the measurement time for each reference symbol does not exceed the duration T13). If the reference symbol with SINR higher than or equal to the twelfth threshold does not exist before the expiration of the first timer, the terminal reports a wireless link out-of-step indication; if the reference symbol with SINR higher than or equal to the thirteenth threshold exists before the expiration of the first timer, the terminal reports a radio link synchronization indication. If, before the expiration of the second timer, there is a reference symbol with an RSRP higher than or equal to the thirteenth threshold and/or an SINR higher than or equal to the fourteenth threshold, the terminal transmits a resource ID of the corresponding reference symbol and/or a corresponding measured SINR/RSRP.

Here, the SINR may be L1-SINR or L3-SINR. The RSRP may be L1-RSRP or L3-RSRP.

In some embodiments, the method further comprises:

SINR or RSRP measurements are made during the T14 period, and the terminal transmits at least one of: index of reference symbol with quality exceeding sixteenth threshold, SINR or RSRP of corresponding reference symbol;

the quality exceeds a sixteenth threshold comprising one of: SINR exceeds the sixteenth threshold and RSRP exceeds the sixteenth threshold.

For example, the terminal makes SINR/RSRP measurements of S reference symbols (the measurement time for each reference symbol does not exceed the T14 duration), the terminal sends the resource ID of the reference symbol with quality exceeding the sixteenth threshold, and/or the corresponding measured SINR/RSRP (for CBD).

Optionally, the method further comprises:

and when the number of the reference symbols with the quality exceeding the sixteenth threshold exceeds the first number threshold, the terminal reports synchronization. Here, the synchronization includes radio link synchronization. The terminal reporting synchronization comprises the following steps: the physical layer reports the synchronization indication to the higher layer. When the synchronization indication continuously reported by the physical layer is greater than or equal to a threshold (e.g., a first number threshold), the terminal reports synchronization to the network device.

Optionally, the method further comprises:

before the second timer expires, the terminal reports synchronization when the number of reference symbols whose quality exceeds the sixteenth threshold exceeds the first number threshold. Here, the synchronization includes radio link synchronization. The terminal reporting synchronization comprises the following steps: the physical layer reports a synchronization instruction to a higher layer; when the synchronization indication continuously reported by the physical layer is greater than or equal to a threshold (e.g., a first number threshold), the terminal reports synchronization to the network device.

Optionally, the method further comprises:

Here, by configuring the seventeenth threshold to be higher than the sixteenth threshold, triggering of the RLM is enabled to be more accurate than triggering of the CBD.

In some embodiments, the respective time lengths (Ti) are determined based on the number of measured reference symbols and the reference symbol periods; i.e. the Ti duration is the number of samples multiplied by the reference symbol period. Where the reference symbols are the same, a larger (longer) Ti represents a larger number of samples and the more accurate the measurement result.

The respective time period (Ti) comprises at least one of: t1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14.

Specifically, the time period T1, the time period T2, the time period T3, the time period T4, the time period T5, the time period T6, the time period T7, the time period T8, the time period T9, the time period T10, the time period T11, the time period T12, the time period T13, and the time period T14 may include 2 scenes. Scene 1: the duration corresponds to a measurement duration of 1 reference symbol; scene 2: the time period corresponds to a total time period for completing the measurement of the plurality of reference symbols.

It should be noted that the above-mentioned thresholds (e.g., the first threshold, the second threshold, the third threshold, … …, and the seventeenth threshold) are set based on the requirements of the practical application, and the values are not limited herein.

The thresholds may be determined by the network device and transmitted to the terminal, may be preset by a protocol, or may be stored in advance at the terminal side, and are not limited herein.
