Description

TECHNICAL FIELD

[0002] In the current 5G NR system, in order to ensure the downlink communication quality of the serving cell, radio link monitoring (RLM) is defined; in order to avoid the influence of beam blocking on transmission performance, so that the network side can quickly recover the transmission from beam failure, beam failure detection (BFD) is defined.

[0003] The UE periodically measures the radio link monitoring reference signal (RLM-RS), the measurement result is the signal to interference plus noise ratio (SINR) value of the reference signal, compares the block error rate (BLER) value corresponding to the SINR value with the in-sync threshold and the out-of-sync threshold, judges the in-sync (IS) / out-of-sync (OOS) state of the UE, and the physical layer indicates the IS / OOS state obtained by the judgment to the RRC layer.

[0004] In addition, the UE can also periodically measure the reference signal (BFD-RS) of the current serving beam, the measurement result is the SINR value of the reference signal, compare the BLER value corresponding to the SINR value with the threshold, judge the quality of the serving beam, and the physical layer reports the result to the MAC layer.

[0140] The execution entities involved in the embodiments of this disclosure include, but are not limited to, terminals (UE, User Equipment) in cellular mobile communication systems and base stations in cellular mobile communication systems.

[0141] Figure 2 This is a flowchart illustrating a communication method according to an exemplary embodiment, such as... Figure 2 As shown, the communication method of this disclosure embodiment is applied to a UE, and the communication method includes the following processing steps:

[0142] Step 201: Check whether the reference signal meets the measurement relaxation condition.

[0143] In this embodiment of the disclosure, the measurement relaxation conditions include: the UE moving at low speed, or the UE being located in the center of the cell, or the UE moving at low speed and being located in the center of the cell.

[0144] Low-speed movement here refers to the communication reference signal meeting certain communication quality indicators. As one implementation method, the communication quality parameters of the measured reference signal are used to determine whether the UE is moving at low speed.

[0145] The reference signal includes at least one of an RLM-RS and a BFD-RS. As an example, the RLM-RS includes at least one of a synchronization signal and a physical broadcast channel (PBCH) block (SSB) and a channel state information reference signal (CSI-RS). The BFD-RS includes at least one of the SSB and the CSI-RS.

[0146] In the embodiments of the present disclosure, the detection of whether the reference signal satisfies the measurement relaxation condition includes:

[0147] The first parameter of the reference signal is detected in a measurement evaluation time window, and a mean value of the first parameter in the measurement evaluation time window is calculated. A difference between a preset reference value and the mean value of the first parameter is calculated.

[0148] In response to the difference being less than a preset mobility threshold, the measurement relaxation condition is satisfied. Or, in response to the difference being greater than or equal to the mobility threshold, the measurement relaxation condition is not satisfied.

[0149] Here, the first parameter includes a signal-to-interference-plus-noise ratio (SINR). As an implementation manner, the first parameter can also be a received power of a signal, etc. In the embodiments of the present disclosure, the UE determines whether the measurement relaxation condition is satisfied through the detection of the reference signal.

[0150] In the embodiments of the present disclosure, when the UE performs cell switching, or when the mean value of the first parameter is greater than the preset reference value, or when the measurement relaxation condition is not satisfied in a set time window, the preset reference value is set as the mean value of the first parameter. The set time window can be a time window for determining whether the difference is less than the preset mobility threshold.

[0151] In the embodiments of the present disclosure, a corresponding preset reference value is also set for the first parameter, a difference between the preset reference value and the mean value of the first parameter in the measurement evaluation time window is calculated, and whether the UE is in a low-speed moving state is determined based on a relationship between the difference and a preset mobility threshold, so as to determine whether the measurement relaxation is performed and the measurement relaxation mode is started.

[0152] As another implementation manner, the detection of whether the reference signal satisfies the measurement relaxation condition further includes:

[0153] The first parameter of the reference signal is detected in a measurement evaluation time window, and a mean value of the first parameter in the measurement evaluation time window is calculated.

[0154] The measurement relaxation condition is met in response to the mean value of the first parameter being greater than a preset cell center threshold, or the measurement relaxation condition is not met in response to the mean value of the first parameter being less than or equal to the cell center threshold.

[0155] Here, the first parameter includes SINR or signal reception power, etc. By setting the cell center threshold, whether the UE is located in the cell center is determined by measuring the size relationship between the mean value of the first parameter in the measurement evaluation time window and the cell center threshold, so as to determine whether the UE meets the measurement relaxation condition. When the measurement relaxation condition is met, the UE starts the measurement relaxation mode, so that the measurement frequency of the UE for the reference signal is reduced, and the purpose of power saving is achieved.

[0156] In the embodiments of the present disclosure, for the scenario of low-speed movement or being located in the cell center, when the reference signal is a BFD-RS, and the measurement relaxation condition is met for the reference signal in all serving cells in carrier aggregation or dual connectivity, the measurement of the reference signal in all serving cells is subjected to measurement relaxation processing; the reference signal is a BFD-RS, and the measurement relaxation condition is not met for the reference signal in at least one serving cell in carrier aggregation or dual connectivity, and the measurement of the reference signal in all serving cells is not subjected to measurement relaxation processing. That is to say, when the reference signal is a BFD-RS, for the case that the UE supports carrier aggregation or dual connectivity, all serving cells corresponding to the carriers supported by the UE need to meet the measurement relaxation condition, and the measurement of the reference signal in all serving cells is subjected to measurement relaxation processing, otherwise, as long as there is a serving cell corresponding to the carriers supported by the UE that does not meet the measurement relaxation condition, the measurement of the reference signal in all serving cells corresponding to the carriers is not subjected to measurement relaxation processing.

[0157] In the embodiments of the present disclosure, the measurement frequency of the UE for the reference signal can also be lower when the UE is in both low-speed movement and the cell center.

[0158] In the embodiments of the present disclosure, as an implementation manner, detecting whether the reference signal meets the measurement relaxation condition further includes:

[0159] detecting a first parameter of the reference signal in a measurement evaluation time window, calculating a mean value of the first parameter in the measurement evaluation time window, and calculating a difference value between a preset reference value and the mean value of the first parameter;

[0160] The measurement relaxation condition is met in response to the difference value being less than a preset mobility threshold and the mean value of the first parameter being greater than a preset cell center threshold;

[0161] Or, in response to the difference being greater than or equal to the mobility threshold, or the mean value of the first parameter being less than or equal to the cell center threshold, the measurement relaxation condition is not met.

[0162] For the case that the UE is in a low-speed moving state and is in a cell center, if the first parameter is greater than a set threshold, the detection of the reference signal is not performed. That is, when the UE is in a low-speed moving state and is in a cell center, if the channel quality condition of the reference signal is good, the detection of the reference signal is not necessary, that is, the detection of the reference signal is suspended. In this case, if the reference signal is a BFD-RS, in response to the reference signal in at least one serving cell of carrier aggregation or dual connectivity meeting the measurement relaxation condition, the measurement of the reference signal in all serving cells is subjected to measurement relaxation processing; in response to the reference signal in all serving cells of carrier aggregation or dual connectivity not meeting the measurement relaxation condition, the measurement of the reference signal in all serving cells is not subjected to measurement relaxation processing.

[0163] Step 202, in response to the reference signal meeting the measurement relaxation condition, the measurement of the reference signal is subjected to measurement relaxation processing.

[0164] In the embodiments of the present disclosure, the measurement relaxation processing of the reference signal includes adjusting at least one of a measurement evaluation period and an indication period of the reference signal. Here, the adjustment of at least one of the measurement evaluation period and the indication period of the reference signal is mainly to prolong at least one of the measurement evaluation period and the indication period.

[0165] In the embodiments of the present disclosure, when the indication period of the reference signal is adjusted, it is necessary to ensure that the indication period is greater than the measurement evaluation period.

[0166] Figure 3 A flowchart of a communication method according to an exemplary embodiment is shown, as shown in Figure 3 The communication method of the embodiments of the present disclosure is applied to a UE, and the communication method includes the following processing steps:

[0167] Step 301, receiving indication information of measurement relaxation.

[0168] Step 302, in response to the indication information, performing measurement relaxation processing.

[0169] In the embodiments of the present disclosure, the indication information includes a measurement window duration and a measurement window period. That is, the network device sends an indication of measurement relaxation to the UE, so that the UE performs reference signal measurement in the measurement window duration, and the UE can sleep in the non-measurement window duration. When the measurement window period comes, the UE starts the measurement relaxation based on the reference signal. In the embodiments of the present disclosure, the measurement window period is K times of the measurement window duration; K≥2.

[0170] When the UE is not configured with the DRX mode, the measurement relaxation is performed according to the measurement window duration in the measurement window period;

[0193]

[0194] REF RLM is RLM-RS SINR reference value, which is a preset value, and can be an empirical value.

[0218] The network configures a cell center threshold SINR_center_BFD, and the UE compares SINR(i) with SINR_center_BFD. If SINR(i) > SINR_center_BFD is satisfied, it is considered that the UE is located at the center of the cell.

[0219] Wherein,

[0220] Condition 13: UE is located at the center of the cell and moving at low speed, i.e., UE satisfies both condition 11 and condition 12.

[0234] In the embodiments of the present disclosure, the network device instructs the UE to perform measurement relaxation behavior by sending RLM or BFD relaxation signaling, and the relaxation signaling configuration includes a measurement window duration parameter T relax_on and a measurement window periodicity parameter relaxation periodicity, wherein, in addition to T relax_on , the UE can enter a sleep state. RLM and BFD can use different periodicity configurations. T relax_on = T evaluation , wherein T evaluation is a measurement evaluation period; and relaxation periodicity > K x T evaluation , wherein K > 2.

[0235] 1) If the network does not configure DRX, the UE performs measurement relaxation according to the relaxation signaling issued by the network device;

[0236] 2) If the network device configures DRX, the UE performs measurement during the DRX active time period (on duration) and when the measurement relaxation instruction T relax_on ;
