[0028] Next, the technical solutions in the embodiments of this application will be clearly described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by this application.

[0029] The terms "first", "second", etc. in this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, the "or" in this application means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, Scenario 1: including A and not including B; Scenario 2: including B and not including A; Scenario 3: including both A and B. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0030] The term "indicate" in this application can be either a direct indication (or an explicit indication) or an indirect indication (or an implicit indication). Among them, a direct indication can be understood as that the sender clearly tells the receiver specific information, operations to be performed, or request results, etc. in the sent indication; an indirect indication can be understood as that the receiver determines the corresponding information according to the indication sent by the sender, or makes a judgment and determines the operations to be performed or request results, etc. according to the judgment result.

[0031] It should be noted that the technology described in the embodiments of this application is not limited to the Long Term Evolution (LTE) or LTE-Advanced (LTE-A) systems, and can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in this application are often used interchangeably. The described technology can be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. The following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions. However, these technologies can also be applied to systems other than NR system applications, such as the 6th th Generation (6G) communication system.

[0032] To facilitate the understanding of the embodiments of this application, the following technical points will be introduced first.

[0033] 1. Regarding the cyclic prefix in the Orthogonal Frequency-Division Multiplexing (OFDM) system.

[0034] In the OFDM system, an OFDM symbol usually consists of two parts. The first part is the CP, and the second part is the time-domain signal obtained after the Inverse Fast Fourier Transform (IFFT). The cyclic prefix is composed of the last NCP sampling points of the second part, as Figure 1 shown.

[0035] Without a CP, there may be inter-symbol interference between two adjacent OFDM symbols. For example, due to multipath delay, the tail of the previous OFDM symbol overlaps with multiple sampling points at the start of the second OFDM symbol, or due to timing error, the Fast Fourier Transform (FFT) time window at the receiving end includes the last multiple sampling points of the previous OFDM symbol and partial sampling points of the current OFDM symbol. Adding a cyclic prefix with a length not less than the total delay (e.g., including transmission delay and delay caused by timing error) can ensure that only the signal of the current OFDM symbol is included within the FFT time window at the receiving end, without inter-symbol interference. It is not difficult to see that the length of the CP is related to the channel environment. For example, in an environment with a small propagation delay, a shorter CP is sufficient to eliminate inter-symbol interference, while in an environment with a large propagation delay, a longer CP is required. Therefore, the New Radio (NR) or Long Term Evolution (LTE) system supports two types of CPs, one called NCP and the other called Extended CP (ECP). The CP can avoid inter-symbol interference, but since the CP part cannot carry additional information, the overhead of the CP part will lead to a reduction in resource efficiency, that is, within one OFDM symbol, the longer the CP, the higher the proportion it occupies, and the lower the transmission efficiency of this OFDM symbol. As shown in Table 1 and Table 2, when using NCP, 14 OFDM symbols can be transmitted in one time slot, and when using ECP, only 12 OFDM symbols can be transmitted in one time slot. In system design, it is usually necessary to consider the trade-off between transmission efficiency and inter-symbol interference.

[0036] Table 1: NCP.

[0037]

[0038] Table 2: ECP.

[0039]

[0040] The NR system can support different subcarrier spacings (SCS). For different SCSs, the ratio of the number of sampling points in the first part (CP) and the second part within the OFDM symbol is the same, thus ensuring the same transmission efficiency. For any SCS, for a specific OFDM symbol, the ratio of the number of sampling points of the first part NCP to the second part is 144:2048. If the first part is ECP, then the ratio is 512:2048. It can be seen that since the ratio of the first part to the second part does not change with the SCS, the time length of the CP part decreases as the SCS increases.

[0041] In the NR system, after evaluation, although the CP length shortens as the SCS increases, in the Frequency Range (FR) 1 scenario, when SCS = 15 KHz and 30 KHz, the NCP length is sufficient to reduce inter-symbol interference. However, when SCS = 60 KHz, the NCP length is insufficient under some channel conditions. Therefore, NCP and ECP are supported when SCS = 60 KHz. In the FR2 and FR2-2 scenarios, due to the reduced coverage range and the use of analog beams, the multipath delay is significantly shorter than that in FR1. Therefore, although the CP length shortens as the SCS increases, the NCP length is still sufficient.

[0042] In addition, for the NR or LTE system, the time and frequency domain deviations of the terminal (e.g., User Equipment (UE)) or the base station caused by hardware need to meet specific requirements. For example, the UE needs to meet the requirement that the Carrier Frequency Offset (CFO) does not exceed 0.1 Parts Per Million (ppm), and the UE regularly corrects the time and frequency domain deviations according to the synchronization signal. Therefore, the length of the CP required due to timing errors can be basically ignored.

[0043] 2. Regarding the measurement configuration of Radio Resource Management (RRM).

[0044] In the NR system, for the UE in the Radio Resource Control (RRC) idle state, the configuration of neighbor cell signal measurement is obtained in the system information. That is, the System Information Block (SIB) 2 provides the co-frequency measurement configuration information, and the SIB4 provides the inter-frequency measurement configuration information. For the UE in the RRC connected state, the configuration of neighbor cell signal measurement is configured through RRC. The configuration information may include the SSB Measurement Timing Configuration (SMTC), the list of SSB indexes (indexlist) to be measured, and whether the SSB index can be obtained through the timing of the serving cell.

[0045] 3. Regarding the communication method and requirements of the Channel-State-Information Reference Signal (CSI-RS).

[0046] Channel State Information Reference Signals for CSI reporting (CSI-RS for CSI reporting) corresponding associated reporting parameters include CSI-RS with CSI reporting configurations that contain Rank Indicator (RI). During the non-active period of Discontinuous Reception (DRX), the UE does not measure these CSI-RS. At the reporting occasion of the CSI-RS, the reporting content is only for CSI reporting of the CSI-RS that was most recently within the DRX active period before the CSI reference resource.

[0047] 4. Regarding Channel State Information Reference Signals for L1-Reference Signal Received Power or L1-Signal-to-Interference-plus-Noise Ratio reporting (CSI-RS for L1-RSRP / L1-SINR reporting).

[0048] CSI-RS for L1-RSRP / L1-SINR reporting corresponding associated reporting parameters include CSI-RS with CSI reporting configurations that contain Layer 1 Reference Signal Received Power (L1-RSRP) or Layer 1 Signal-to-Interference-plus-Noise Ratio (L1-SINR). During the non-active period of DRX, the UE does not measure these CSI-RS. Therefore, the requirements for the measurement period of CSI-RS-based L1-RSRP or L1-SINR are related to the DRX configuration.

[0049] 5. Regarding CSI-RS for Radio Link Monitoring (RLM).

[0050] Specifically, CSI-RS for RLM is configured as the CSI-RS targeted at RLF in the RadioLinkMonitoringConfig. During the non-active period of DRX, the UE does not measure these CSI-RS. Therefore, for each configured CSI-RS, the requirements for the measurement period are related to the DRX configuration.

[0051] 6. Regarding CSI-RS for beam failure detection (BFD).

[0052] The CSI-RS for RLM is configured in RadioLinkMonitoringConfig as the CSI-RS targeted for BFD. During the non-active period of DRX, the UE does not measure these CSI-RSs. Therefore, the requirement for the measurement period for each configured CSI-RS is related to the DRX configuration.

[0053] 7. Regarding CSI-RS for candidate beam detection (CBD).

[0054] The CSI-RS for CBD corresponds to the CSI-RS configured in the beam failure recovery configuration (BeamFailureRecoveryConfig) or the beam failure recovery reference signal configuration (BeamFailureRecoveryRSConfig-r16) in Release 16. When DRX <= 320 ms, during the non-active period of DRX, the UE needs to measure these CSI-RSs. When DRX > 320 ms, during the non-active period of DRX, the UE does not need to measure these CSI-RSs. Therefore, the requirement for the measurement period for each configured CSI-RS is related to the DRX configuration.

[0055] 8. Regarding CSI-RS for RRM.

[0056] The CSI-RS for RRM corresponds to the CSI-RS configured in CSI-RS Resource Configuration Mobility (CSI-RS-ResourceConfigMobility). Among them, the CSI-RS for RRM is divided into the CSI-RS belonging to the serving cell and the neighbor cell. During the non-active period of DRX, the UE does not measure these CSI-RSs. When the DRX cycle is greater than 80 ms, the UE does not expect these CSI-RSs to be available. Therefore, the requirement for the measurement period for each configured CSI-RS is related to the DRX configuration.
