[0028] The example headings for the various sections below are used to facilitate understanding of the subject matter described and do not limit the scope of the subject matter claimed in any way. Consequently, one or more features of an example section may be combined with one or more features of another example section. Furthermore, the terminology 5G is used for the sake of clarity of explanation, but the techniques described herein are not limited to 5G technology and may be used in wireless systems that implement other protocols. I. Introduction
[0029] In many cases, a Base Station (BS) is expected to provide data transmission services to multiple User Equipment (UEs) with different speeds of movement. The different speeds of movement will lead to different channel switching speeds between the BS and the UEs. To improve the quality of service, the BS needs to acquire Time Domain Channel Property (TDCP), which is a type of Channel State Information (CSI) that represents the channel switching speed, and consequently configure the corresponding service policies for different UEs. Generally, TDCP is measured by the UE through Tracking Reference Signals (TRS) and then reported to the BS. However, the configuration of CSI-RS features and quantization schemes in TDCP reports have not been specified.
[0030] In this patent document, the following embodiments are provided for addressing the problem of TDCP report configuration:
[0031] CSI-RS resources associated with a TDCP report;
[0032] Quantization schemes. Petition 870260031282, dated 02 / 04 / 2026, page 11 / 117 7 / 53
[0033] Details of the modalities are presented below.
[0034] TDCP is a type of CSI that represents the channel speed change between the UE and the BS. TDCP is typically applied in two scenarios: the high-speed rail scenario and the highway scenario. The high-speed rail scenario is illustrated in Figure 1, where there are 6 Remote Radio Heads (RRHs). To save on the transfer procedure, some of the RRHs correspond to the same cell. This means that there is a long, narrow cell along a railway. Similarly, there are several Transmit / Receive Points (TRPs) deployed along an expressway.
[0035] Generally, a TDCP report includes one or multiple amplitudes and / or phases of channel correlations. The channel correlation c(t) is measured using a special type of CSI-RS called TRS, for which two or four CSI-RS features are configured in two consecutive slots. Detailed specifications of the TRS can be found in [clause 5.1.6.1.1 TS 38.214].
[0036] Although the current specifications [TS 38.212 38.214] have specified the CSI reporting configuration in detail, these specifications are probably inadequate for the TDCP, since the TDCP differs greatly from other CSIs in terms of reporting magnitudes and measurement mechanism.
[0037] In this patent document, three embodiments are presented for addressing the TDCP reporting configuration problem, including aspects of the CSI-RS features associated with TDCP reporting, the CSI-RS emissions used to calculate TDCP, and the quantization schemes of the reporting quantities.
[0038] First, explanations of some terminology to be used in the patent document are presented.
[0039] Note that, in this patent document, UE is equivalent to a wireless communication device. Petition 870260031282, dated 02 / 04 / 2026, p. 12 / 117 8 / 53
[0040] Note that, in this patent document, BS is equivalent to a wireless networking device, the Next Generation B Node (gNB), or TRP.
[0041] Note that, in this patent document, TRS is equivalent to RS, CSI-RS, CSI-RS Tracking, CSI-RS for Tracking.
[0042] Note that, in this patent document, CSIRS feature is equivalent to Non-Zero Power (NZP) CSI-RS feature, CSI-RS feature set is equivalent to NZP CSI-RS feature set.
[0043] Note that, in this patent document, TDCP is equivalent to CSI, TDCP report is equivalent to CSI report.
[0044] Note that, in this patent document, upper layer signaling or upper layer parameter is equivalent to Radio Resource Control (RRC), RRC parameter, Radio Resource Management (RRM), Radio Resource Arrangement (RRA), Downlink Control Information (DCI), or Downlink Physical Control Channel (PDCCH).
[0045] Note that, in this patent document, time unit may be subsymbol, symbol, slot, subframe, frame or transmission occasion.
[0046] Note that, in this patent document, channel correlation is equivalent to channel autocorrelation and channel correlation coefficient. II. Implementation Example 1: General Description
[0047] The TDCP measurement and reporting procedure generally includes the following steps:
[0048] The UE receives upper layer signaling.
[0049] The EU receives DCI, triggering a TDCP report.
[0050] The EU measures TDCP using the TRS transmitted by Petition 870260031282, dated 02 / 04 / 2026, page 13 / 117 9 / 53 base station.
[0051] A TDCP report includes the following quantities:
[0052] Y>1 amplitudes of channel correlations;
[0053] Y>1 phases of channel correlations if the top layer parameter PhaseReport is set to on.
[0054] The channel correlation c(t) is measured through the TRS by the following formula ^n^oMt +τ)h^t)C(T) = I ------- I----1Σ„ΐΛ„α + τ)ΐ21Σ„ΐΛ„ωι2where τ denotes delay or lag, hn(t) denotes the channel response for the subcarrier n at time te ()* denotes conjugate operation.
[0055] The UE reports the TDCP to BS via the Physical Uplink Shared Channel (PUSCH) indicated by the DCI. III. Example 2: CSI-RS Resources Associated with a TDCP Report
[0056] The general structure of CSI-RS resource configuration is illustrated in Figure 2. A CSI report configuration is associated with one or more periodic and / or aperiodic CSI resource configurations. Each CSI resource configuration includes one or more sets of CSI-RS resources, and each set of CSI-RS resources includes one or more CSI-RS resources. An aperiodic CSI report is triggered by the CSI request field in DCI. The CSI request field indicates a CSI trigger state in the top-layer parameter CSI-AperiodicTriggerStateList. The CSI trigger state indicates the CSI report configuration and the set(s) of CSI-RS resources used to calculate the CSI.

[00145] This patent document provides a method for addressing the problem of measuring and reporting TDCP:
[00146] CSI-RS resources associated with a TDCP report;
[00147] Quantization schemes,
[00148] where a modality provides a flexible way of Petition 870260031282, dated 02 / 04 / 2026, page 34 / 117 30 / 53 configure the CSI-RS resources used to measure TDCP, and one modality provides a highly efficient way to quantify the amplitudes and phases of channel correlations in a TDCP report.
[00149] Figure 3 is an exemplary flowchart for sending a TDCP report. Operation 302 involves receiving, by a wireless device, a channel state information (CSI) report configuration associated with one or more CSI resource configurations, where each CSI resource configuration of the one or more CSI resource configurations includes a set of CSI reference signal resources (CSI-RS), and where the set of CSI-RS resources includes one or more CSI-RS resources. Operation 304 involves receiving, by the wireless device, a list of CSI trigger states. Operation 306 involves determining, by the wireless device, a time-domain channel property (TDCP) based on the CSI report configuration and the list of CSI trigger states. Operation 308 involves sending, by the wireless device, a TDCP report. In some embodiments, the method can be implemented according to Embodiments 1-3.In some applications, performing additional steps in the method may be based on better system performance than a legacy protocol.
[00150] In some modalities, the CSI reporting configuration is associated with an aperiodic CSI feature configuration, where the aperiodic CSI feature configuration includes a CSI-RS feature set.

[00179] Figure 11 shows an illustrative block diagram of a hardware platform 1100 that may be part of a network device (e.g., base station) or a communication device (e.g., a user equipment (UE)). The hardware platform 1100 includes at least one processor 1110 and a memory 1105 with stored instructions. The instructions, when executed by the processor 1110, configure the hardware platform 1100 to perform the operations described in FIGS. 1 to 10 and in the various embodiments described in this patent document. The transmitter 1115 transmits or sends information or data to another device. For example, a network device transmitter may send a message to a user equipment. The receiver 1120 receives information or data transmitted or sent by another Petition 870260031282, dated 02 / 04 / 2026, page 54 / 117 50 / 53 device. For example, a user device can receive a message from a network device. For example, a UE or a network device, as described in this document, can be implemented using the 1100 hardware platform.
[00180] The implementations discussed above will apply to wireless communication. Figure 12 shows an example of a wireless communication system (e.g., a 5G or NR cellular network) that includes a base station 1220 and one or more user equipment (UE) 1211, 1212, and 1213. In some embodiments, the UEs access the BS (e.g., the network) using a communication link with the network (sometimes called the uplink direction, as represented by the dashed arrows 1231, 1232, 1233), which then allows subsequent communication (e.g., shown in the direction from the network to the UEs, sometimes called the downlink direction, shown by the arrows 1241, 1242, 1243) from the BS to the UEs.In some embodiments, the BS sends information to the UEs (sometimes called downlink direction, as represented by arrows 1241, 1242, 1243), which allows subsequent communication (e.g., shown in the direction from the UEs to the BS, sometimes called uplink direction, shown by dashed arrows 1231, 1232, 1233) from the UEs to the BS. The UE can be, for example, a smartphone, a tablet, a mobile computer, a machine-to-machine (M2M) device, an Internet of Things (IoT) device, and so on. The UEs described in this document can be communicatively coupled to the base station 1220 represented in Figure 12. The UEs can also communicate with the BS for CSI communications.
[00181] It will be appreciated by someone with knowledge of the art that the present document describes methods for determining more accurate precoding matrices, especially in the case where different frequency locations correspond to different matrices. Petition 870260031282, dated 02 / 04 / 2026, page 55 / 117 51 / 53 pre-coding, while the overhead of reporting pre-coding matrices by the UE (or reported by the base station) does not increase. More accurate information about the channel status can be obtained due to the more precise pre-coding matrices. Thus, spectrum efficiency is improved.
