Claims 2-4 and 12-14 are rejected under 35 U.S.C. 103 as being unpatentable over Liu in view of Sun and Yang as applied to claims 1, 10, 11, or 20 above, and in further view of Vilaipornsawai et al (US20180124733A1) (hereinafter "Vilaipornsawai").
Regarding claim 2, Liu, as modified by Sun and Yang, fails to disclose the method, wherein information regarding a duration of the TDRS part is obtained through network signaling.
However, Vilaipornsawai discloses the method, wherein information regarding a duration of the TDRS part is obtained through network signaling ([0152] For example, in some embodiments, a UE is provided with inputs, such as, UE-ID, a seed (for pseudo random generator) which can be a group-specific or UE-specific seed signaled by RRC signaling, e.g. MAC CE enabled (between dynamic DCI and high level RRC signaling), NR cell ID (e.g. hypercell ID), a security key (for security), and a time instant (for time varying output parameters). Based on these inputs, the UE derives the tracking signal parameters and TF resource that have been assigned to it by the network. These include, for example: [0153] Tracking signal format, including CP/GT/BW [0154] ZC sequence related parameters, which can be time varying, e.g. [0155] Sequence length).

The motivation to combine both references would come from the need to resist channel multipath effects.
Regarding claim 3, Liu, as modified by Sun and Yang, discloses the method, wherein the information regarding the duration of the TDRS part indicates a ratio of the TDRS part and the CP part ([0095] Therefore, in this embodiment of this application, by mapping the sequence to the set, an original CP can be extended by using a sequence with a flexible length, such as UW or ZT, so that the CP can be flexibly extended, and flexible guard periods of different lengths can be configured for all users by adjusting the length of the sequence. [0202] Therefore, the CP can be extended by using a sequence, such as UW or ZT, with a flexible length, so that an inter-symbol guard period is flexibly configured.).
Regarding claim 4, Liu, as modified by Sun and Yang, fails to disclose the method, wherein the network signaling is downlink control information (DCI) or radio resource control (RRC) signaling.
However, Vilaipornsawai discloses the method, wherein the network signaling is downlink control information (DCI) or radio resource control (RRC) signaling ([0152] For example, in some embodiments, a UE is provided with inputs, such as, UE-ID, a seed (for pseudo random generator) which can be a group-specific or UE-specific seed signaled by RRC signaling, e.g. MAC CE enabled (between dynamic DCI and high level RRC signaling), NR cell ID (e.g. hypercell ID), a security key (for security), and a time instant (for time varying output parameters). Based on these inputs, the UE derives the tracking signal parameters and TF resource that have been assigned to it by the network.
