Description

Method and device for measuring wireless link, terminal, base station and storage medium

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for measuring a radio link, a terminal, a base station, and a storage medium.

Background

With the continuous progress of radio technology, various radio services are greatly emerged, and the spectrum resources supported by the radio services are limited, so that the spectrum resources between 300MHz and 3GHz mainly used by the traditional commercial communication show a very tight situation in the face of the continuous increase of the bandwidth requirements of people, and the requirements of the future wireless communication cannot be met.

In future wireless communication, carrier frequencies higher than those adopted by fourth generation (4G) communication systems are expanded to be supported for communication, such as 28GHz, 45GHz and the like, and potential operating frequency bands of the systems reach 100 GHz. In a high frequency band (greater than 6GHz), because the attenuation of electromagnetic waves is large, a beamforming method is usually required to resist the attenuation of signals, and the transmission distance of the signals is increased. Thus, signals are typically transmitted or received in the form of beams. In general, the base station configures one or more beams with better quality for the terminal to perform communication. And because the signal quality of the beam can be changed all the time, the configured beam also needs to be changed all the time, so that the signal quality of the beam used by the terminal can meet the communication requirement all the time.

In order to ensure normal communication, a terminal (user equipment, UE for short) needs to periodically detect the quality of a current link, and periodically send an indication to a higher layer according to a measurement result, so that the higher layer knows the state of the current terminal. For example, when the quality of a signal IS greater than a certain threshold, the physical layer of the terminal reports synchronization (in sync, IS for short) to the higher layer; when the quality of the signal is less than a certain threshold, the terminal reports out of sync (OOS for short) to the high layer. Since there are multiple beams available for the terminal and the base station, the base station configures multiple reference signal resources for the terminal to detect its link quality. As the number of resources of the configured reference signal increases, the more signals the terminal needs to detect each time, which results in the complexity and power consumption of its measurement radio link increasing.

In the related art, a reasonable solution is not provided for the problem that the complexity and power consumption of the terminal for measuring the wireless link are increased due to the fact that the base station configures a plurality of reference signal resources for the terminal to detect the link quality.

Example 3

In order to better understand the technical solution of the present invention, the following detailed description of the embodiments of the present invention is provided.

In a mobile communication system, a UE needs to periodically measure a downlink reference signal and evaluate the current link quality according to the measurement result. Typically, after the UE obtains a measurement result, the measurement result needs to be filtered (fi filtering) before link quality evaluation, and then the filtered measurement result is used for link quality evaluation. Suppose that the UE has M measurement results in time sequence₀,M₁,M₂,.., one possible method of filtering is

F_n＝(1-a)·F_n-1+a·M_n

Wherein M is_nFor the most recent measurement, F_nAs a result of the filtering, F_nFor radio link quality assessment, F_n-1As a result of a previous filtering, i.e. M_n-1And F is the result of the filtering of₀＝M₀And a is a filtering coefficient and is a configured constant.

The downlink reference signal detected by the UE is a periodically transmitted signal-to-ratioFor example, a Synchronization signal block (SS block) or a Channel state information reference signal (CSI-RS) is periodically transmitted, and in the embodiment of the present invention, the downlink reference signal is collectively referred to as a Radio link monitoring parameter signal (RLM-RS). The network side can configure one or more RLM-RS resources for UE detection, so that at one measurement time, the UE can obtain one or more measurement results M_n(one measurement per RLM-RS resource), one or more filtered results F can be obtained by the above filtering formula_n. Among the RLM-RS resources detected by the UE, the signal quality of one RLM-RS resource is greater than a threshold Q _ in, that is, one F_nIf the value IS greater than Q _ in, the UE physical layer reports an IS indication to the higher layer. When the signal quality of all RLM-RS resources is less than Q _ out, that is, all F_nAll values of the OOS are smaller than Q _ in, and the UE physical layer reports an OOS indication to a high layer.

Time length for IS evaluation of UE IS T_inIt should be noted that the length of the IS evaluation time herein and the aforementioned IS evaluation period may be understood as the same configuration parameter. UE evaluation T_inThe signal quality in the time period is that each RLM-RS resource respectively obtains an F_nIf there is one F_nIf the value of the value IS larger than the threshold Q _ in, the UE physical layer reports an IS indication to a high layer. The length of time for OOS evaluation is T_oosIt should be noted that the OOS evaluation time duration and the OOS evaluation period may be understood as the same configuration parameter. UE evaluation T_oosThe signal quality in the time period is that each RLM-RS resource respectively obtains an F_nIf all F_nAll values of (2) are smaller than the threshold Q _ out, and the UE physical layer reports an OOS indication to a high layer. Measurement period of T_MDenotes every T_MThe UE detects the configured RLM-RS resource; IS or OOS indicates that the reporting period IS T_IIndicates that the UE is every T_IThe UE physical layer reports an IS or OOS indication to the high layer, and the IS or OOS indication reports a period T_IIs the measurement period T of the UE_MIS indicationReporting period T of_IIS estimation time length T of UE_inThe maximum value of the reporting period of the OOS indication is the OOS evaluation time length T of the UE_OOS. Fig. 7 is a diagram of an alternative terminal high-layer declaration of the occurrence of a radio link failure according to an embodiment of the present invention. As shown in fig. 7, the UE starts a timer T1 after receiving N1 OOS indications consecutively in the higher layer. When the timer T1 IS running, the timer T1 IS stopped if the UE receives N2 IS within T1 time. If the timer T1 expires, the UE still does not receive N2 IS, and the higher layer declares that a radio link failure has occurred.

In order to better understand the technical solutions in the embodiments of the present invention, the following is a specific example by way of a preferred embodiment.
