Abstract

An embodiment of the invention provides a communication apparatus comprising a radio transceiver and a modem processor. The radio transceiver is configured to transmit or receive wireless signals in a wireless network. The modem processor is coupled to the radio transceiver and configured to perform operations comprising: dividing a tracking reference signal (TRS) set into a plurality of TRS subsets; scheduling a first part of the plurality of TRS subsets for a beam management; and scheduling a second part of the plurality of TRS subsets for a synchronization.

First claim

What is claimed is:

1 . A communication apparatus, comprising:
a radio transceiver, transmitting or receiving wireless signals in a wireless network; and a modem processor, coupled to the radio transceiver and configured to perform operations comprising: dividing a tracking reference signal (TRS) set into a plurality of TRS subsets; scheduling a first part of the plurality of TRS subsets for a beam management; and scheduling a second part of the plurality of TRS subsets for a synchronization.

2 . The communication apparatus of claim 1 , wherein a third part of the plurality of TRS subsets is not available (N/A).

3 . The communication apparatus of claim 1 , wherein the communication apparatus schedules a fourth part of the plurality of TRS subsets for at least one measurement.

4 . The communication apparatus of claim 3 , wherein the at least one measurement comprises at least one of a control element (CE) measurement, a network element (NE) measurement, a channel state information (CSI) measurement, a radio link monitoring (RLM) measurement or a Layer 1 Reference Symbol Received Power (L1-RSRP) measurement.

5 . The communication apparatus of claim 3 , wherein the second part of the plurality of TRS subsets and the fourth part of the plurality of TRS subsets are overlapped.

6 . The communication apparatus of claim 1 , wherein the first part of the plurality of TRS subsets comprises a plurality of first non-continuous TRS subsets.

7 . The communication apparatus of claim 1 , wherein the second part of the plurality of TRS subsets comprises a plurality of second non-continuous TRS subsets.

8 . The communication apparatus of claim 1 , wherein the first part of the plurality of TRS subsets and the second part of the plurality of TRS subsets are overlapped.

9 . The communication apparatus of claim 1 , wherein the TRS set comprises a plurality of TRS symbols.

10 . A communication apparatus, comprising:
a radio transceiver, transmitting or receiving wireless signals in a wireless network; and a modem processor, coupled to the radio transceiver and configured to perform operations comprising: scheduling a tracking reference signal (TRS) set for a beam management or a synchronization as default; dividing the TRS set into a plurality of TRS subsets, scheduling a first part of the plurality of TRS subsets for the beam management, and scheduling a second part of the plurality of TRS subsets for the synchronization, if an average (AR) signal-to-noise ratio (SNR) of the TRS set is not smaller than a first threshold and a one-shot (OS) SNR of the TRS set is not smaller than a second threshold; and scheduling the TRS set for the beam management or the synchronization, if the AR SNR of the TRS set is not greater than a third threshold or the OS SNR of the TRS set is not greater than a forth threshold.

11 . The communication apparatus of claim 10 , wherein a third part of the plurality of TRS subsets is not available (N/A).

12 . The communication apparatus of claim 10 , wherein the communication apparatus schedules a fourth part of the plurality of TRS subsets for at least one measurement.

13 . The communication apparatus of claim 12 , wherein the at least one measurement comprises at least one of a control element (CE) measurement, a network element (NE) measurement, a channel state information (CSI) measurement, a radio link monitoring (RLM) measurement or a Layer 1 Reference Symbol Received Power (L1-RSRP) measurement.

14 . The communication apparatus of claim 12 , wherein the second part of the plurality of TRS subsets and the fourth part of the plurality of TRS subsets are overlapped.

15 . The communication apparatus of claim 10 , wherein the first part of the plurality of TRS subsets comprises a plurality of first non-continuous TRS subsets.

16 . The communication apparatus of claim 10 , wherein the second part of the plurality of TRS subsets comprises a plurality of second non-continuous TRS subsets.

17 . The communication apparatus of claim 10 , wherein the first part of the plurality of TRS subsets and the second part of the plurality of TRS subsets are overlapped.

18 . The communication apparatus of claim 10 , wherein the TRS set comprises a plurality of TRS symbols.

19 . A method for handling a tracking reference signal (TRS) scheduling, comprising:
dividing a tracking reference signal set into a plurality of TRS subsets; scheduling a first part of the plurality of TRS subsets for a beam management; and scheduling a second part of the plurality of TRS subsets for a synchronization.

20 . A method for handling a tracking reference signal (TRS) scheduling, comprising:
scheduling a tracking reference signal set for a beam management or a synchronization as default; dividing the TRS set into a plurality of TRS subsets, scheduling a first part of the plurality of TRS subsets for the beam management, and scheduling a second part of the plurality of TRS subsets for the synchronization, if an average (AR) signal-to-noise ratio (SNR) of the TRS set is not smaller than a first threshold and a one-shot (OS) SNR of the TRS set is not smaller than a second threshold; and scheduling the TRS set for the beam management or the synchronization, if the AR SNR of the TRS set is not greater than a third threshold or the OS SNR of the TRS set is not greater than a forth threshold.
