[0189] The present invention will be further described in detail below with reference to the embodiments, starting with a description of the relevant technologies.

[0190] As mentioned above, in existing technologies, the reference symbols for RLM, BFD, CBD, L1-RSRP, and L1-SINR are configured independently by the network, and each UE performs the corresponding process independently. This presents the following problems:

[0191] 1. Reference symbols used for different purposes may be configured repeatedly, but in the prior art they are configured independently, resulting in a waste of signaling overhead;

[0192] 2. RLM, BFD, CBD, L1-RSRP, and L1-SINR are performed independently by the UE. The terminal performs its own independent measurement and monitoring process for different purposes, resulting in wasted terminal power consumption.

[0193] In other words, in the existing technology, RLM, BFD, CBD, L1-RSRP, and L1-SINR are independent UE behaviors. In extreme cases, the terminal needs to start a total of 5 monitoring processes, namely RLM, BFD, CBD, L1-RSRP, and L1-SINR, which is highly complex and consumes a lot of power.

[0194] In fact, RLM, BFD, CBD, L1-RSRP, and L1-SINR are all related to link quality. These independent UE processes can be integrated or coordinated to reduce terminal power consumption and improve system performance.

[0195] Based on this, the present invention proposes an integrated scheme for RLM, BFD, CBD, RSRP, SINR resource configuration and terminal behavior, which realizes the monitoring of the above-mentioned RLM, BFD, CBD, RSRP, and SINR through a single mechanism or fewer mechanisms. For example, the monitoring of RLM, BFD, CBD, RSRP, and SINR can be realized simultaneously through a single process, thereby reducing complexity and terminal power consumption.

[0196] The present invention will be further described in detail below with reference to the embodiments.

[0197] Figure 1 A communication method provided in an embodiment of the present invention, such as Figure 1 As shown, the method is applied to terminals such as mobile phones, smartphones, laptops, digital radio receivers, personal digital assistants (PDAs), tablet computers (PADs), portable multimedia players (PMPs), wearable devices (such as smart bracelets, smartwatches, etc.), navigation devices, etc.; the method includes:

[0198] Step 101: Receive first information; the first information includes the index of the reference symbol and / or first indication information;

[0199] The first indication information is used for at least one of the following:

[0200] The reference symbol is used for at least one of the following measurements: RLM, BFD, CBD, RSRP, SINR;

[0201] Instructs the execution of one or more of RLM, BFD, and CBD;

[0202] Indicates measurement of one or more of RSRP, SINR, SS-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP, CSI-RSRQ, and CSI-SINR.

[0203] In some embodiments, the index of the reference symbol represents the identifier of the reference symbol, and the index of the reference symbol may be described as a resource identifier (ID).

[0204] In some embodiments, a reference symbol can be associated with multiple purposes among RLM, BFD, CBD, RSRP, and SINR. That is, the measurement results of the reference symbol can be used for multiple purposes. The first indication information is used to indicate which measurement or monitoring purpose the reference symbol corresponding to a certain reference symbol index can be used for.

[0205] In some embodiments, the first information includes the index of the reference symbol and / or first indication information. The first indication information is used to indicate that when performing one or more of RLM, BFD, and CBD, it can be understood that the first indication information indicates that at least two of the above operations are performed based on the same, same group, or same set of reference symbols.

[0206] Here, at least two objectives are achieved based on measurement results from the same, same set, or same set of reference symbols. The main purpose of this operation is to fulfill multiple requirements in RLM, BFD, and CBD based on the same measurement mechanism or the same process.

[0207] Unlike existing technologies where RLM, BFD, CBD, L1-RSRP, and L1-SINR are configured and measured independently, resulting in wasted resources and power consumption, this invention achieves multiple requirements for RLM, BFD, and CBD through the same measurement mechanism or process, saving resources and avoiding power waste.

[0208] In some embodiments, the first information includes the index of the reference symbol and / or first indication information, the first indication information being used to indicate one or more of RSRP, SINR, SS-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP, CSI-RSRQ, and CSI-SINR. It can be understood as completing the measurement of the measured quantity in RSRP, SINR, SS-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP, CSI-RSRQ, and CSI-SINR based on the reference symbol in the first information, and the measurement result can be used for RLM, BFD, and CBD.

[0209] In some embodiments, receiving the first information includes: receiving first information from a network device. That is, the network device determines and sends the first information, and the terminal receives the first information accordingly.

[0210] In some embodiments, the reference symbol includes at least one of the following: a synchronization signal block (SSB) and a channel state information reference signal (CSI-RS).

[0211] In some embodiments, the number of reference symbols indicated by the first information is N; where N ≥ 1;

[0212] The number of reference symbols used for at least two measurements is M; wherein M ≤ N;

[0213] M and N are integers.

[0214] In some embodiments, the first information includes: the index of the reference symbol and the measurement purpose corresponding to the reference symbol.

[0215] In practical applications, different groups of measurements can be performed based on the same resource ID reference symbol.

[0216] Based on this, in some embodiments, the method further includes: performing at least one set of the following measurements based on a reference symbol:

[0217] RLM, BFD, CBD;

[0218] RLM, BFD;

[0219] RLM, CBD;

[0220] RSRP, SINR;

[0221] RLM, BFD, CBD, RSRP, SINR.

[0222] That is, for a reference symbol with the same resource ID, the measurements of each of the above groups can be performed.

[0223] For example, regarding RLM, BFD, and CBD, considering that both RLM and BFD are related to link monitoring, RLM monitors the overall quality of the link, including synchronization monitoring and out-of-synchronization monitoring; BFD is for beam-level quality detection; and CBD is for discovering candidate beams for beam recovery.

[0224] In some embodiments, the RSRP includes: Layer 1 Reference Signal Received Power (L1-RSRP) and Layer 3 Reference Signal Received Power (L3-RSRP).

[0225] The SINR includes: Layer 1 signal to interference plus noise ratio (L1-SINR) and Layer 3 signal to interference plus noise ratio (L3-SINR).

[0226] That is, the measured SINR can be either L1-SINR or L3-SINR. The measured RSRP can be either L1-RSRP or L3-RSRP.

[0227] In some embodiments, the method further includes at least one of the following:

[0228] SINR is measured within a time period T1. When the SINR of all P reference symbols is lower than or equal to the first threshold, the terminal reports BFD; where P is a positive integer.

[0229] SINR is measured within time T2. When the SINR of Q reference symbols is lower than or equal to the second threshold, the terminal reports a loss of synchronization; where Q is a positive integer.

[0230] SINR measurement is performed within the T3 time period. When the SINR of at least one reference symbol is higher than or equal to the third threshold, the terminal reports synchronization.

[0231] SINR measurement is performed within the T4 time period, and the terminal sends the index and / or SINR of the reference symbol whose SINR is higher than or equal to the fourth threshold;

[0232] RSRP is measured within the T5 time period, and the terminal sends the index and / or RSRP of the reference symbol whose RSRP is higher than or equal to the fifth threshold.

[0233] Here, the durations T1, T2, T3, T4, and T5 can include two scenarios. Scenario 1: This duration corresponds to the measurement duration of one reference symbol; Scenario 2: This duration corresponds to the total duration of measuring multiple reference symbols.

[0234] Given that BFD is beam-level monitoring while RLM is overall link monitoring, even if BFD and RLM are performed based on reference symbols with the same resource ID, it is desirable to trigger BFD and RLM separately. In practical applications, this consideration is taken into account:

[0235] Furthermore, the first threshold is lower than the second threshold, meaning that compared to the loss of synchronization of RLM, the terminal can trigger beam failure more easily;

[0236] Furthermore, the T1 duration is shorter than the T2 duration, meaning that compared to the RLM's loss of synchronization, the terminal can trigger beam failure more quickly;

[0237] Furthermore, the number of resources used for RLM is greater than the number of resources used for BFD, i.e., N>M.

[0238] Additionally, the loss of synchronization includes wireless link loss of synchronization. Terminal reporting of loss of synchronization includes: the terminal's physical layer reporting a loss of synchronization indication to higher layers; when the physical layer continuously reports loss of synchronization indications greater than or equal to a threshold, the terminal reports the loss of synchronization to the network device. This reporting can also be described as sending.

[0239] Specifically, considering that CBD is beam-level monitoring while RLM is overall link monitoring, even if CBD and RLM are performed based on reference symbols with the same resource ID, it is desirable to trigger CBD and RLM separately. In practical applications, this consideration is taken into account:

[0240] Furthermore, the third threshold is higher than the fourth / fifth threshold, meaning that compared to RLM synchronization, the terminal can more easily report candidate beams;

[0241] Furthermore, the T3 duration is longer than the T4 / T5 duration, meaning that compared to RLM synchronization, the terminal can report candidate beams more quickly.

[0242] Furthermore, the number of resources used for RLM is greater than the number of resources used for CBD.

[0243] Additionally, the synchronization includes wireless link synchronization. Terminal synchronization reporting includes: the physical layer reporting synchronization indications to higher layers; and when the physical layer continuously reports synchronization indications greater than or equal to a threshold, the terminal reports synchronization to the network device.

[0244] Specifically, the SINR and RSRP transmitted by the terminal include measurement results of reference symbols with quality above a threshold. This transmission can also be described as reporting.

[0245] Specifically, the durations T1, T2, T3, T4, and T5 are determined based on the number of reference symbols being measured and the period of those reference symbols.

[0246] In some embodiments, the method further includes at least one of the following:

[0247] If the SINR of X reference symbols detected within the first time window is all lower than or equal to a first quality threshold, a first measurement result is obtained; the first measurement result includes a beam failure indication (BFD); X is a positive integer;

[0248] When the SINR of the Y reference symbols detected within the second time window is all lower than or equal to the second quality threshold, a second measurement result is obtained; the second measurement result includes Radio Link Sense (RLM) out-of-sync; where Y is a positive integer;

[0249] A third measurement result is obtained when the SINR of Z consecutive reference symbols detected within the third time window is higher than or equal to the third quality threshold; the third measurement result includes Radio Link Sense (RLM) synchronization; Z is a positive integer.

[0250] If a reference symbol with an L1-RSRP higher than or equal to the fourth mass threshold is detected within the fourth time window, a fourth measurement result is obtained; the fourth measurement result includes at least one of the following: an L1-RSRP higher than or equal to the fourth mass threshold, or the index of the reference symbol corresponding to an L1-RSRP higher than or equal to the fourth mass threshold.

[0251] If a reference symbol with an L1-SINR higher than or equal to the fifth quality threshold is detected within the fifth time window, a fifth measurement result is obtained; the fifth measurement result includes at least one of the following: an L1-SINR higher than or equal to the fifth quality threshold, or the index of the reference symbol corresponding to an L1-SINR higher than or equal to the fifth quality threshold.

[0252] In some embodiments, the method further includes:

[0253] Determine the SINR and / or RSRP of the reference symbol;

[0254] The measurement results are determined based on the SINR and / or RSRP of the reference symbol, at least one offset value, and the corresponding target threshold.

[0255] The at least one offset value is sent by the network device, or the at least one offset value is predetermined based on the protocol.

[0256] The method further includes: obtaining at least one offset value.

[0257] In the case where the at least one offset value is sent by a network device, obtaining the at least one offset value includes: receiving the at least one offset value sent by the network device. For example... Figure 2 As shown, Figure 2 This is a flowchart illustrating a communication method provided in an application embodiment of the present invention.

[0258] In practical applications, considering that measurement results obtained by processing measurements intended for a specific purpose can be used for other purposes, the measurement burden on the terminal can be reduced, frequent measurements can be avoided, and power consumption can be reduced. RLM is an assessment of the overall link quality, which places high demands on the measurement results. BFD and CBD measurements are beam-level measurements, so the measurement results used for BFD and CBD, combined with a certain quality offset value, can yield more stable measurement results for use in RLM.

[0259] Based on this, in some embodiments, the at least one offset value includes: the first offset value, the second offset value, the third offset value, the fourth offset value, and the fifth offset value.

[0260] The method further includes at least one of the following:

[0261] SINR is obtained based on BFD and the first offset value, and can be used for RLM;

[0262] SINR is obtained based on CBD and the second offset value, and can be used for RLM;

[0263] RSRP is obtained based on CBD and the third offset value, and can be used for RLM;

[0264] RSRP is obtained based on L1-RSRP and the fourth offset value, and can be used for CBD;

[0265] SINR, derived from L1-SINR and the fifth offset value, can be used for BFD.

[0266] Here, the SINR of BFD can be understood as: the SINR obtained by measuring the reference symbol in order to perform beam failure detection (BFD); the SINR of BFD can be used to determine whether BFD has occurred;

[0267] Similarly, the SINR of the CBD can be understood as: the SINR obtained by measuring the reference symbol for candidate beam detection (CBD); the SINR of the CBD can be used to determine whether a candidate beam has been found.

[0268] The RSRP of the CBD can be understood as: the RSRP obtained by measuring the reference symbol for candidate beam detection (CBD); the RSRP of the CBD can be used to determine whether a candidate beam has been found.

[0269] Here, the RSRP obtained based on L1-RSRP and the fourth offset value (resulting in L3-RSRP with RSRP as the reference symbol) can also be used for candidate beam detection (CBD).

[0270] The SINR obtained based on L1-SINR and the fifth offset value (resulting in L3-SINR with RSRP as the reference symbol) can also be used for beam failure detection (BFD).

[0271] New SINR and RSRP are obtained based on BFD, CBD SINR, RSRP and various offset values, which can be used for RLM synchronization and out-of-sync.

[0272] It should be noted that the value and specific function of each offset value are pre-configured by the network device or protocol based on the actual application, and are not specifically limited here.

[0273] In practical applications, to reduce the measurement burden on the terminal, avoid frequent measurements, and reduce power consumption, it is desirable to be able to perform other purposes based on measurement results used for certain purposes. Therefore, a method is provided to process the threshold and offset values ​​used for BFD and CBD to obtain new threshold values; the new threshold values ​​can be used for synchronization and out-of-sync evaluation of RLM.

[0274] Based on this, in some embodiments, the method further includes at least one of the following:

[0275] When the SINR of BFD is lower than or equal to a first new threshold, the terminal reports a loss of synchronization; the first new threshold is obtained based on the threshold used for BFD and the first offset value;

[0276] When the SINR of BFD is higher than or equal to the second new threshold, the terminal reports synchronization; the second new threshold is obtained based on the threshold and the second offset value used for BFD.

[0277] When the SINR of CBD is higher than or equal to the third new threshold, the terminal reports synchronization; the third new threshold is obtained based on the threshold and the third offset value used for CBD.

[0278] When the SINR of CBD is lower than or equal to the fourth new threshold, the terminal reports a loss of synchronization; the fourth new threshold is obtained based on the threshold used for CBD and the fourth offset value;

[0279] When the RSRP of the CBD is higher than or equal to the fifth new threshold, the terminal reports synchronization; the fifth new threshold is obtained based on the threshold and the fifth offset value used for the CBD.

[0280] The offset values ​​here (first offset, second offset, third offset, fourth offset, and fifth offset) can be either RSRP or SINR. These offset values ​​can take multiple values, and different values ​​can be used in different scenarios. No specific limitation is made here.

[0281] In some embodiments, determining the measurement result based on the SINR and / or RSRP of the reference symbol, at least one offset value, and a corresponding target threshold includes at least one of the following:

[0282] Corresponding to the case of using the SINR for BFD measurement, a first SINR is determined based on the SINR and a first offset value; the first SINR of K consecutive reference symbols detected within a T6 time period is determined to be lower than or equal to a sixth threshold, and a sixth measurement result is obtained; the sixth measurement result includes Radio Link Sense (RLM) out-of-sync; K is a positive integer;

[0283] Corresponding to the case of using the SINR for CBD measurement, a second SINR is determined based on the SINR and the second offset value; the second SINR of L consecutive reference symbols detected within a T7 time period is determined to be higher than or equal to a seventh threshold, and a seventh measurement result is obtained; the seventh measurement result includes Radio Link Sense (RLM) synchronization; where L is a positive integer;

[0284] Corresponding to the case of L1-RSRP used for CBD measurement, a first L1-RSRP is determined based on the L1-RSRP and the third offset value; the first L1-RSRP of R consecutive reference symbols detected within a T8 time period is determined to be higher than or equal to the eighth threshold, and an eighth measurement result is obtained; the eighth measurement result includes CBD step loss; R is a positive integer.

[0285] In some embodiments, the method further includes at least one of the following:

[0286] RSRP measurement is performed within the T9 duration, and the terminal sends the index of the reference symbol whose RSRP is higher than or equal to the ninth threshold and / or RSPR;

[0287] SINR and RSRP are measured within the T10 time period. When the RSRP of the reference symbol is higher than or equal to the ninth threshold and the SINR is higher than or equal to the tenth threshold, the terminal reports synchronization.

[0288] Here, SINR can be either L1-SINR or L3-SINR. RSRP can be either L1-RSRP or L3-RSRP.

[0289] The terminal reporting synchronization includes: the terminal physical layer reporting synchronization indications to higher layers; when the synchronization indications continuously reported by the physical layer are greater than or equal to a threshold, the terminal reports synchronization to the network device.

[0290] For example, the terminal performs an L1-RSRP measurement for a reference symbol during time T9. The terminal's physical layer sends the resource ID, and / or L1-RSRP, to the higher layers if the L1-RSRP is higher than or equal to the ninth threshold.

[0291] The terminal performs an L1-SINR measurement for a certain reference symbol within time T10. When L1-RSRP is greater than the ninth threshold and L1-SINR is greater than the tenth threshold, the terminal's physical layer reports a synchronization indication to the higher layer.

[0292] In some embodiments, the method further includes:

[0293] If the SINR of all reference symbols detected within the T11 time period is lower than or equal to the eleventh threshold, the first timer and / or the second timer are started.

[0294] Before the first timer expires, SINR is measured within the duration of T12. When the SINR of all detected reference symbols is lower than or equal to the twelfth threshold, the terminal reports a loss of synchronization; when the SINR of at least one reference symbol is higher than or equal to the thirteenth threshold, the terminal reports synchronization.

[0295] Before the second timer expires, SINR measurement is performed within duration T12 and / or RSRP measurement is performed within duration T13. When the RSRP of at least one reference symbol is higher than or equal to the fourteenth threshold and / or the SINR is higher than or equal to the fifteenth threshold, the terminal sends at least one of the following: the index of the reference symbol whose RSRP is higher than or equal to the fourteenth threshold and / or whose SINR is higher than or equal to the fifteenth threshold, the SINR and / or RSRP of the corresponding reference symbol.

[0296] Here, terminal reporting of loss of synchronization includes: terminal reporting of radio link loss of synchronization indication; terminal reporting of synchronization includes: terminal reporting of radio link synchronization indication.

[0297] For example, the terminal performs SINR measurements on W reference symbols (the measurement time for each reference symbol does not exceed T11 duration). When the quality (e.g., SINR) of V reference symbols is all below or equal to the eleventh threshold, the terminal's physical layer reports a beam failure indication (BFD) to the higher layers.

[0298] Simultaneously, the terminal starts the first timer and the second timer, and performs SINR measurements for U reference symbols (the measurement time for each reference symbol does not exceed T12 duration) and / or RSRP measurements for I reference symbols (the measurement time for each reference symbol does not exceed T13 duration). If no reference symbol with SINR higher than or equal to the twelfth threshold exists before the first timer expires, the terminal reports a radio link out-of-synchronization indication; if a reference symbol with SINR higher than or equal to the thirteenth threshold exists before the first timer expires, the terminal reports a radio link synchronization indication. If a reference symbol with RSRP higher than or equal to the thirteenth threshold and / or SINR higher than or equal to the fourteenth threshold exists before the second timer expires, the terminal sends the resource ID of the corresponding reference symbol and / or the corresponding measured SINR / RSRP.

[0299] Here, SINR can be either L1-SINR or L3-SINR. RSRP can be either L1-RSRP or L3-RSRP.

[0300] In some embodiments, the method further includes:

[0301] During the T14 time period, SINR or RSRP measurements are performed, and the terminal sends at least one of the following: the index of the reference symbol whose quality exceeds the sixteenth threshold, or the SINR or RSRP of the corresponding reference symbol;

[0302] The quality exceeding the sixteenth threshold includes one of the following: SINR exceeding the sixteenth threshold, RSRP exceeding the sixteenth threshold.

[0303] For example, the terminal performs SINR / RSRP measurements for S reference symbols (the measurement time for each reference symbol does not exceed T14 duration), and the terminal sends the resource ID of the reference symbol whose quality exceeds the sixteenth threshold, and / or the corresponding measured SINR / RSRP (for CBD).

[0304] Optionally, the method further includes:

[0305] When the number of reference symbols whose quality exceeds the sixteenth threshold exceeds a first number threshold, the terminal reports synchronization. Here, synchronization includes radio link synchronization. The terminal reporting synchronization includes: the physical layer reporting synchronization indications to higher layers. When the synchronization indications continuously reported by the physical layer are greater than or equal to a threshold (such as the first number threshold), the terminal reports synchronization to the network device.

[0306] Optionally, the method further includes:

[0307] Before the second timer expires, when the number of reference symbols whose quality exceeds the sixteenth threshold exceeds the first number threshold, the terminal reports synchronization. Here, synchronization includes radio link synchronization. The terminal reporting synchronization includes: the physical layer reporting synchronization indications to higher layers; when the synchronization indications continuously reported by the physical layer are greater than or equal to a threshold (such as the first number threshold), the terminal reports synchronization to the network device.

[0308] Optionally, the method further includes:

[0309] The terminal reports synchronization when the quality of at least one reference symbol exceeds the seventeenth threshold.

[0310] Here, by configuring the seventeenth threshold to be higher than the sixteenth threshold, the triggering of RLM is made more accurate than that of CBD.

[0311] In some embodiments, the corresponding duration (Ti) is determined based on the number of reference symbols and the reference symbol period; that is, the Ti duration is the number of samples multiplied by the reference symbol period. With the same number of reference symbols, a larger (longer) Ti indicates a larger number of samples and more accurate measurement results.

[0312] The corresponding duration (Ti) includes at least one of the following: T1 duration, T2 duration, T3 duration, T4 duration, T5 duration, T6 duration, T7 duration, T8 duration, T9 duration, T10 duration, T11 duration, T12 duration, T13 duration, and T14 duration.

[0313] Specifically, the durations T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, and T14 can include two scenarios. Scenario 1: This duration corresponds to the measurement duration of one reference symbol; Scenario 2: This duration corresponds to the total time required to complete the measurement of multiple reference symbols.

[0314] It should be noted that the thresholds mentioned above (such as the first threshold, the second threshold, the third threshold, ..., the seventeenth threshold) are set based on the needs of actual applications, and there are no restrictions on their values ​​here.

[0315] In addition, each threshold can be determined by the network device and sent to the terminal, or it can be preset by the protocol, or it can be saved in advance on the terminal side; there are no restrictions here.

The base station can be a Base Transceiver Station (BTS) in GSM or CDMA, a NodeB (NB) in WCDMA, or an Evolutionary Node B (eNB or e-NodeB) in LTE.
