DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

The terms "first", "second", etc. of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited, for example, the first object can be one or more. In addition, "or" in the present application represents at least one of the connected objects. For example, "A or B" covers three schemes, namely, Scheme 1: including A but not including B; Scheme 2: including B but not including A; Scheme 3: including both A and B. The character "/" generally indicates that the objects associated with each other are in an "or" relationship.

The term "indication" in this application can be a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, operations to be performed, or request results in the sent indication; an indirect indication can be understood as the receiver determining the corresponding information according to the indication sent by the sender, or making a judgment and determining the operation to be performed or the request result according to the judgment result.

It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) or LTE-Advanced (LTE-A) system, but 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" of the present application are often used interchangeably, and the described technology can be used for the above-mentioned systems and radio technologies as well as other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following descriptions, but these technologies can also be applied to systems other than NR system applications, such as the ^6th Generation (6G) communication system.

In order to facilitate understanding of the implementation methods of the present application, the following technical points are first introduced below.

1. About the cyclic prefix in the orthogonal frequency-division multiplexing (OFDM) system.

In an 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 consists of the last NCP sampling points of the second part, as shown in Figure 1.

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

Table 1: NCPs.

Table 2: ECPs.

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 of the OFDM symbol is the same, thereby ensuring the same transmission efficiency. For any SCS, for a specific OFDM symbol, the ratio of the number of sampling points in the first part NCP to the second part is 144:2048. If the first part is ECP, 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 with the increase of the SCS.

In the NR system, after evaluation, although the CP length becomes shorter with the increase of SCS, in the frequency range (FR) 1 scenario, when SCS = 15KHz and 30KHz, the NCP length is also sufficient to reduce inter-symbol interference, but when SCS = 60KHz, the NCP length is not long enough under some channel conditions, so NCP and ECP are supported when SCS = 60KHz. In FR2 and FR2-2 scenarios, due to the smaller coverage range, the use of analog beams significantly shortens the multipath delay compared to FR1. Therefore, although the CP length becomes shorter with the increase of SCS, the length of NCP is still sufficient.

In addition, for NR or LTE systems, the time and frequency domain deviation of the terminal (e.g., User Equipment (UE)) or base station caused by hardware must meet specific requirements, such as the UE must meet the carrier frequency domain deviation (CFO) of no more than 0.1 parts per million (ppm), and the UE must regularly correct the time and frequency domain deviation according to the synchronization signal. Therefore, the length of the CP required due to the timing error can be basically ignored.

2. About Radio Resource Management (RRM) measurement configuration.

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

3. Communication methods and requirements for Channel-State-Information Reference Signal (CSI-RS).

The channel state information reference signal (CSI-RS for CSI reporting) for channel state information reporting corresponds to the CSI-RS configured for CSI reporting with the Rank Indicator (RI) as the associated reporting parameter. During the non-active period of Discontinuous Reception (DRX), the UE does not measure these CSI-RS. At the reporting occasion of CSI-RS, the reporting content is only for the CSI-RS in the DRX active period that is closest to the CSI reference resource.

4. Channel state information reference signal (CSI-RS for L1-RSRP/L1-SINR reporting) for L1-reference signal received power or L1-signal to interference and noise ratio reporting.

CSI-RS for L1-RSRP/L1-SINR reporting The corresponding associated reporting parameters include the CSI-RS configured for CSI reporting of 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 L1-RSRP or L1-SINR based on CSI-RS are related to the DRX configuration.

5. About CSI-RS used for radio link monitoring (RLM).

Specifically, the CSI-RS used for RLM corresponds to the CSI-RS configured as the RLF target 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 measurement period requirement is related to the DRX configuration.

6. About CSI-RS used for beam failure detection (BFD).

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

7. About CSI-RS used for candidate beam detection (CBD).

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 version 16. When DRX <= 320ms, the UE needs to measure these CSI-RS during the non-active period of DRX. When DRX> 320ms, the UE does not need to measure these CSI-RS during the non-active period of DRX. Therefore, for each configured CSI-RS, the measurement period requirement is related to the DRX configuration.

8. Regarding CSI-RS used for RRM.

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