Abstract

A wireless communication method for use in a wireless terminal is disclosed. The wireless communication method comprises receiving, from the wireless network node, a second signal based on a quasi-co-location assumption of a first signal when at least one event occurs, wherein the first signal and the second signal overlap in at least one time unit.

First claim

What is claimed is:

1. A wireless communication method for use in a wireless terminal, the wireless communication method comprising:
prioritizing a reception of a first signal in response to at least one event occurring,
wherein the first signal and a second signal overlap in at least one time unit,
wherein the at least one event comprises first information associated with the first signal and is the same as the first information associated with the second signal,
wherein the first information associated with the first signal comprises the first information associated with a TCI state applicable to the first signal, and
wherein the first information associated with the second signal comprises the first information associated with a TCI state applicable to the second signal,
wherein the TCI state applicable to the first signal comprises a TCI state indicated by downlink control information (DCI) for the first signal, and wherein the TCI state applicable to the second signal comprises at least one of a TCI state indicated by DCI for the second signal, a TCI state activated by a medium access control control element (MAC-CE), for a default CORESET of the second signal, or a TCI state corresponding to the lowest codepoint in a plurality of TCI codepoints comprising a plurality of TCI states applicable to the second signal.

2. The wireless communication method of claim 1 , wherein the prioritizing the reception of the first signal comprises at least one of:
receiving only the first signal; or
not receiving the second signal.

3. The wireless communication method of claim 2 , wherein the at least one event comprises at least one of:
an offset between a physical downlink control channel (PDCCH) scheduling the second signal and the second signal is smaller than a threshold,
the first signal is indicated having a transmission configuration indicator, TCI, state,
second information associated with the first signal is the same with the second information associated with the second signal,
wherein the first information comprises at least one of a panel index or a set, and
wherein the second information comprises at least one of a control resource set (CORESET) group, a component carrier (CC) or a CC group.

4. The wireless communication method of claim 3 , wherein the panel index is configured in at least one of: a TCI state, a channel state information (CSI) report, a CORESET, a CORESET group, a CC, or a CC group, or wherein the set comprises at least one of a TCI state or a reference signal (RS).

5. The wireless communication method of claim 3 , wherein the first information associated with the first signal comprises the first information associated with an RS applicable to the first signal, and wherein the first information associated with the second signal comprises the first information is associated with an RS applicable to the second signal.

6. The wireless communication method of claim 5 , wherein the RS applicable to the first signal comprises a QCL RS in a TCI state indicated by DCI for the first signal, and wherein the RS applicable to the second signal comprises at least one of a QCL RS in a TCI state indicated by DCI for the second signal, a QCL RS in a TCI state activated by a MAC-CE for a default CORESET of the second signal, a QCL RS in a TCI state corresponding to the lowest codepoint in a plurality of TCI codepoints comprising a plurality of TCI states applicable to the second signal, or a QCL RS applicable to a default CORESET of the second signal.

7. The wireless communication method of claim 3 , wherein the second information associated with the first signal comprises the second information associated with a CORESET scheduling the first signal, and
wherein the second information associated with the second signal comprises at least one of the second information associated with a CORESET scheduling the second signal or the second information associated with a default CORESET of the second signal.

8. The wireless communication method of claim 3 , wherein the first information associated with the first signal comprises the first information associated with the second information associated with the first signal, wherein the first information associated with the second signal comprises the first information associated with the second information associated with the second signal.

9. The wireless communication method of claim 8 , wherein the first information associated with the second information associated with the first signal comprises the first information associated with the second information associated with a CORESET scheduling the first signal, and wherein the first information associated with the second information associated with the second signal comprises at least one of the first information associated with the second information associated with a CORESET scheduling the second signal or the first information associated with the second information associated with a default CORESET of the second signal.

10. The wireless communication method of claim 2 , wherein one of the first signal or the second signal comprises at least one of a PDCCH, a physical downlink shared channel (PDSCH), a CSI-RS, or an aperiodic CSI-RS.

11. A wireless terminal, comprising:
a processor, configured for prioritizing a reception of a first signal in response to at least one event occurring, wherein the first signal and the second signal overlap in at least one time unit,
wherein the at least one event comprises first information associated with the first signal and is the same as the first information associated with the second signal,
wherein the first information associated with the first signal comprises the first information associated with a TCI state applicable to the first signal, and
wherein the first information associated with the second signal comprises the first information associated with a TCI state applicable to the second signal,
wherein the TCI state applicable to the first signal comprises a TCI state indicated by downlink control information (DCI) for the first signal, and wherein the TCI state applicable to the second signal comprises at least one of a TCI state indicated by DCI for the second signal, a TCI state activated by a medium access control control element (MAC-CE), for a default CORESET of the second signal, or a TCI state corresponding to the lowest codepoint in a plurality of TCI codepoints comprising a plurality of TCI states applicable to the second signal.

12. The wireless terminal of claim 11 , further comprising a processor configured for:
prioritizing a reception of a first signal in response to at least one event occurring, wherein the first signal and a second signal overlap in at least one time unit; wherein the prioritizing the reception of the first signal comprises at least one of:
receiving only the first signal; or
not receiving the second signal.

13. A non-transitory computer program product comprising a computer-readable program medium code stored thereupon, the code, in response to being executed by a processor, causing the processor to implement the wireless communication method recited in claim 1 .
