[0030] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0031] The terms "first", "second", etc. in this 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 the same type, and do not limit the number of objects, for example, the first object can be one or more. In addition, "or" in this application represents at least one of the connected objects. For example, "A or B" covers three options, namely, Option 1: including A but not including B; Option 2: including B but not including A; Option 3: including both A and B. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0032] The term "indication" in this application can be either 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, the operation to be performed, or the requested result, etc. in the instruction sent; an indirect indication can be understood as the receiver determining the corresponding information based on the instruction sent by the sender, or making a judgment and determining the operation to be performed or the requested result, etc. based on the judgment result.

[0033] It is worth noting that the technology described in the embodiments of the present application is not limited to Long Term Evolution (LTE) or LTE-Advanced (LTE-A) systems, 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" in this application are often used interchangeably, and the technology described can be used for the systems and radio technologies mentioned above, as well as for 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 description, but these technologies can also be applied to systems other than NR system applications, such as 6th generation (6G) systems. th Generation, 6G) communication system.

[0034] In order to facilitate understanding of the implementation of this application, the following technical points are first introduced below.

[0035] 1. About the cyclic prefix in the orthogonal frequency-division multiplexing (OFDM) system.

[0036] In an OFDM system, an OFDM symbol typically consists of two parts: the CP and the time-domain signal obtained through an inverse fast Fourier transform (IFFT). The cyclic prefix consists of the last NCP samples of the second part, as shown in Figure 1.

[0037] Without a CP, intersymbol interference (ISI) may exist between two adjacent OFDM symbols. For example, due to multipath delay, the tail of the previous OFDM symbol may overlap with multiple sampling points at the beginning of the second OFDM symbol. Or, due to timing error, the Fast Fourier Transform (FFT) time window at the receiver includes the last multiple sampling points of the previous OFDM symbol and some sampling points of the current OFDM symbol. Adding a cyclic prefix, whose length is no less than the total delay (e.g., including the delay caused by transmission delay and timing error), ensures that the FFT time window at the receiver only includes the signal of the current OFDM symbol, eliminating ISI. It is not difficult to see that the length of the CP is related to the channel environment. For example, in environments with small propagation delay, a shorter CP is sufficient to eliminate ISI, while in environments with large propagation delay, a longer CP is required. Therefore, New Radio (NR) or Long Term Evolution (LTE) systems support two types of CP: NCP and Extended CP (ECP). CP can prevent inter-symbol interference (ISI), but because it cannot carry additional information, its overhead reduces resource efficiency. Specifically, the longer the CP is and the greater its proportion within an OFDM symbol, the lower the transmission efficiency of that OFDM symbol. As shown in Tables 1 and 2, with NCP, 14 OFDM symbols can be transmitted in one slot, while with ECP, only 12 OFDM symbols can be transmitted. System design typically requires a trade-off between transmission efficiency and ISI.

[0038] Table 1: NCPs.

[0039] Table 2: ECP.

[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 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 as the SCS increases.

[0041] In NR systems, evaluation has shown that while the CP length shortens with increasing SCS, in Frequency Range (FR) 1 scenarios, the NCP length is sufficient to reduce inter-symbol interference when SCS = 15 kHz and 30 kHz. However, when SCS = 60 kHz, the NCP length is insufficient under certain channel conditions. Therefore, NCP and ECP are supported when SCS = 60 kHz. In FR2 and FR2-2 scenarios, due to the reduced coverage area, analog beams are used, and multipath delay is significantly shorter than in FR1. Therefore, although the CP length shortens with increasing SCS, the NCP length remains sufficient.

[0042] Furthermore, for NR or LTE systems, the time and frequency domain deviations of terminals (e.g., user equipment (UE)) or base stations caused by hardware must meet specific requirements. For example, the UE must meet a carrier frequency offset (CFO) of no more than 0.1 parts per million (ppm), and the UE must regularly correct the time and frequency domain deviations based on synchronization signals. Therefore, the length of the CP required to mitigate timing errors is essentially negligible.

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

[0044] 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, the 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 the SSB Measurement Timing Configuration (SMTC), the list of SSB indices to be measured, and whether the SSB index can be obtained through the timing of the serving cell.

[0045] 3. Communication methods and requirements for the Channel-State-Information Reference Signal (CSI-RS).

[0046] The Channel State Information Reference Signal (CSI-RS) for CSI reporting corresponds to the CSI-RS configured for CSI reporting and has an associated reporting parameter that includes a Rank Indicator (RI). During the non-active period of discontinuous reception (DRX), the UE does not measure these CSI-RS. During the CSI-RS reporting occasion, the reporting content is only for the CSI-RS within the DRX active period that is closest to the CSI reference resource.

[0047] 4. Channel State Information Reference Signal (CSI-RS) for L1-RSRP / L1-SINR reporting.

[0048] CSI-RS for L1-RSRP / L1-SINR reporting corresponds to the CSI-RS configured for CSI reporting, and the associated reporting parameters include Layer 1 Reference Signal Received Power (L1-RSRP) or Layer 1 Signal-to-Interference-plus-Noise Ratio (L1-SINR). During the DRX inactive period, the UE does not measure these CSI-RS. Therefore, the requirements for the CSI-RS-based L1-RSRP or L1-SINR measurement period are related to the DRX configuration.

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

[0050] Specifically, the CSI-RS used for RLM corresponds to the CSI-RS configured as the RLF target in the RadioLinkMonitoringConfig. During the DRX inactive period, the UE does not measure these CSI-RS. Therefore, the measurement period requirement for each configured CSI-RS is related to the DRX configuration.

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

[0052] The CSI-RS used for RLM corresponds to the CSI-RS configured for BFD in RadioLinkMonitoringConfig. During the DRX inactive period, the UE does not measure these CSI-RS. Therefore, the measurement period requirement for each configured CSI-RS depends on the DRX configuration.

[0053] 7. About CSI-RS used 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 is less than or equal to 320ms, the UE needs to measure these CSI-RS during the DRX inactive period. When DRX is greater than 320ms, the UE does not need to measure these CSI-RS during the DRX inactive period. Therefore, the measurement period requirement for each configured CSI-RS is related to the DRX configuration.

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

[0056] The CSI-RS used for RRM corresponds to the CSI-RS configured in the CSI-RS resource configuration mobility (CSI-RS-ResourceConfigMobility). The CSI-RS for RRM is divided into CSI-RS belonging to the serving cell and neighboring cells. During the DRX inactive period, 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.

[0182] In an embodiment of the present application, a network-side device sends a wireless measurement configuration to a terminal, so that the terminal can determine a cyclic prefix of a first signal associated with the wireless measurement configuration based on first information in the wireless measurement configuration; and the terminal can measure the first signal based on the cyclic prefix, so that the terminal can support measurement of first signals of multiple cyclic prefix types, thereby meeting measurement requirements of different deployment scenarios or terminal types.

[0183] The following describes the implementation of the present application in conjunction with Examples 1 to 4.

[0184] Example 1:

[0185] In this embodiment, the first signal includes SSB.

[0186] For a UE in an RRC idle or inactive state, it receives the intra-frequency cell reselection configuration or the inter-frequency cell reselection configuration through system information, and performs intra-frequency or inter-frequency SSB measurement after the intra-frequency cell reselection configuration or the inter-frequency cell reselection configuration meets the triggering condition.

[0187] 1) Example of explicit configuration of the first information.

[0188] In some embodiments, if the intra-frequency cell reselection configuration or the inter-frequency cell reselection configuration includes first information, all SSBs associated with the intra-frequency cell reselection configuration or the inter-frequency cell reselection configuration are measured according to the first information.

[0189] In some embodiments, one or more SMTCs in the intra-frequency cell reselection configuration or the inter-frequency cell reselection configuration include first information (i.e., the first information is introduced through the SMTC), then all SSBs associated with the SSB measurement timing configuration are measured according to the first information, that is, measurement is performed according to the configured first information within the time window of the SSB measurement timing configuration;

[0190] Optionally, when the SSB measurement time configuration is associated with one or more cells, the SSBs corresponding to these cells are measured according to the first information.

[0191] In some embodiments, one or more SMTCs in the same-frequency cell reselection configuration or the different-frequency cell reselection configuration may include multiple sub-measurement windows (i.e., the sub-measurement window is introduced through the SMTC), and the first information is configured in each sub-measurement window. Then, the SSB associated with the SMTC is measured according to the first information configured therein within the sub-measurement window, i.e., the SSB is measured according to the first information corresponding to each sub-measurement window of the SMTC.

[0192] Optionally, when the SMTC is associated with one or more cells, the SSBs corresponding to these cells are measured according to the first information corresponding to each of the sub-measurement windows.

[0193] Optionally, each sub-measurement window of the SMTC may be associated with one or more cells, and the SSBs corresponding to these cells are measured in the corresponding sub-measurement windows according to the first information corresponding to each cell.

[0194] In some embodiments, when one or more cells are included in the SMTC, multiple first information are configured to correspond to some of the one or more cells, for example, N first information are configured to correspond to N cells (one-to-one) or M cells (one-to-many, many-to-one), where N and M are integers greater than or equal to 1.

[0195] In some embodiments, when one or more first information are included in the inter-frequency cell reselection configuration, and the first information corresponds to one or more measurement frequency configurations in the inter-frequency cell reselection configuration, the SSB associated with the measurement frequency configuration is measured according to the corresponding first information.

[0196] In some embodiments, when the intra-frequency cell reselection configuration or the inter-frequency cell reselection configuration includes one or more first information, and the first information corresponds to one or more SSBs, the one or more SSBs are measured according to the corresponding first information.

[0197] For the above example:

[0198] Optionally, the first information is only valid for the SSB of a neighbor cell.

[0199] Optionally, the SSB of the serving cell obeys the serving cell configuration or the first information that has been determined.

[0200] Optionally, when the SSB is not configured with the first information, the SSB is determined as a default cyclic prefix (eg, a normal cyclic prefix).

[0201] 2) Implicit configuration example of the first information.

[0202] In some embodiments, in the inter-frequency cell reselection configuration, the first information is determined according to a frequency band or frequency range in which the measurement frequency is located.

[0203] In some embodiments, in the intra-frequency cell reselection configuration or the inter-frequency cell reselection configuration, the first information (eg, extended cyclic prefix) is determined according to the applicable type of SMTC, eg, NTN.

[0204] Example 2:

[0205] In this embodiment, the first signal includes SSB or CSI-RS.

[0206] For UEs in RRC connected state, they receive mobility measurement object configuration via proprietary information and can perform measurements based on SSB or CSI-RS.

[0207] For SSB-based mobility measurement, its implementation method can refer to the operations in Example 1 and will not be repeated here.

[0208] For CSI-RS based mobility measurements:

[0209] 1) Example of explicit configuration of the first information.

[0210] In some embodiments, the mobility measurement configuration includes first information, and all CSI-RS measurements associated with the configuration are performed according to the first information.

[0211] In some embodiments, the mobility measurement configuration includes one or more first information (eg, a first information list), the first information corresponding to one or more cells, and the CSI-RS associated with each cell is measured according to the corresponding first information.

[0212] In some embodiments, a CSI-RS resource set configuration in a mobility measurement configuration includes a first information, and all CSI-RSs associated with the set are measured according to the first information. The CSI-RS resource set is a resource configuration including CSI-RSs of one or more cells.

[0213] In some embodiments, each CSI-RS resource configuration in the mobility measurement configuration includes a first information, and the CSI-RS associated with the CSI-RS resource configuration is measured according to the first information.

[0214] For the above example:

[0215] Optionally, the first information is only valid for the CSI-RS of the neighbor cell.

[0216] Optionally, the CSI-RS of the serving cell complies with the serving cell configuration or the determined first information;

[0217] Optionally, when the CSI-RS is not configured with the first information, the CSI-RS is determined to be a default cyclic prefix (eg, a normal cyclic prefix).

[0218] 2) Implicit configuration example of the first information.

[0219] In some embodiments, the cyclic prefix of the CSI-RS may be determined by its associated SSB, for example, the cyclic prefix or type of the CSI-RS may be the same as the cyclic prefix of the associated SSB.

[0220] In some embodiments, the CSI-RS may be determined based on the frequency range or SCS in which it is located.

[0221] Example 3:

[0222] In this embodiment, the first signal includes but is not limited to SSB or CSI-RS.

[0223] In this embodiment, the wireless measurement configuration is a wireless link detection configuration or a CSI measurement configuration or a beam failure detection configuration or a candidate beam measurement configuration for serving cell measurement.

[0224] In some embodiments, the wireless measurement configuration includes first information, and all first signal measurements associated with the wireless measurement configuration measure the first signal according to the first information.

[0225] In some embodiments, the first information is configured according to resource granularity or resource group granularity in the above-mentioned wireless measurement configuration, and all first signal measurements associated with the resource granularity or resource group granularity are performed according to the configured first information.

[0226] In some embodiments, the first information is introduced into a report configuration (eg, a CSI report configuration), and all first signal measurements associated with the report configuration measure the first signal according to the first information.

[0227] Optionally, the first information is configured in a measurement resource (eg, a CSI resource set or a CSI resource), but the first information corresponding to the measurement resources of the same report configuration is the same.

[0228] Example 4:

[0229] In this embodiment, the first signal includes but is not limited to SSB or CSI-RS.

[0230] In some embodiments, for different cyclic prefixes, the time domain position or time domain pattern of the first signal within a time slot is different.

[0231] In some embodiments, the measurement requirements of the first signal are different for different cyclic prefixes, that is, the requirements of the measurement period, evaluation period or reporting period are related to the cyclic prefix type.
