Abstract

A method for a user equipment (UE) is provided. The method includes receiving first information related to reception of reference signals (RSs). The RSs include channel state information RSs (CSI-RS) or synchronization signals. The RSs are associated with a beam failure (BF) detection, a radio link failure (RLF) detection, or a CSI report. The method further includes receiving second information related to hypothetical adaptation of transmission powers of the RSs and the RSs based on the first information. The method further includes determining, based on the second information and the reception of the RSs, reporting quantities indicating hypothetical channel conditions and transmitting a channel with the reporting quantities indicating the hypothetical channel conditions.

Claims (78)

1 . A method for a user equipment (UE), the method comprising:

receiving:

first information related to reception of reference signals (RSs), wherein:

the RSs include channel state information RSs (CSI-RS) or synchronization signals,

the RSs are associated with a beam failure (BF) detection, a radio link failure (RLF) detection, or a CSI report,

second information related to hypothetical adaptation of transmission powers of the RSs, and

the RSs based on the first information;

determining, based on the second information and the reception of the RSs, reporting quantities indicating hypothetical channel conditions; and

transmitting a channel with the reporting quantities indicating the hypothetical channel conditions.

2 . The method of claim 1 , wherein:

the second information includes offset values to actual transmission powers of the RSS, and

the offset values are separately signaled and applied to respective RSs or commonly signaled and applied to all of the RSs related to the first information.

3 . The method of claim 1 , wherein the reporting quantities indicate information related to a hypothetical BF or RLF and include at least one of:

a reference signal received power (RSRP),

a reference signal received quality (RSRQ),

a signal to interference and noise ratio (SINR), and

a block error rate (BLER) of a hypothetical physical downlink control channel (PDCCH) reception.

4 . The method of claim 1 , wherein the reporting quantities indicate an occurrence of a BF instance or an RLF instance at the hypothetical adaptation of transmission powers of the RSs.

5 . The method of claim 1 , further comprising:

receiving third information related to determination of the reporting quantities including one or more conditions for transmitting the reporting quantities indicating a hypothetical BF or RLF,

wherein transmitting the channel with the reporting quantities further comprises transmitting the channel with the reporting quantities indicating the hypothetical BF or RLF at the hypothetical adaptation of transmission powers of the RSs satisfying the one or more conditions.

6 . The method of claim 1 , further comprising:

receiving an indication on an actual adaptation of transmission powers of one or more RSs; and

determining a CSI report associated with the one or more RSs based on the actual adaptation of transmission powers of the one or more RSs.

7 . The method of claim 1 , further comprising:

receiving an indication on an actual adaptation of transmission powers of one or more RSs; and

determining a CSI report associated with the one or more RSs based on occasions of the one or more RSs received (i) no later than a CSI reference resource and (ii) no earlier than the reception of the indication on the actual adaptation of transmission powers of the one or more RSs.

8 . A user equipment (UE) comprising:

a transceiver configured to receive:

first information related to reception of reference signals (RSs), wherein:

the RSs include channel state information RSs (CSI-RS) or synchronization signals,

the RSs are associated with a beam failure (BF) detection, a radio link failure (RLF) detection, or a CSI report,

second information related to hypothetical adaptation of transmission powers of the RSs, and

the RSs based on the first information; and

a processor operably coupled with the transceiver, the processor configured to determine, based on the second information and the reception of the RSs, reporting quantities indicating hypothetical channel conditions,

wherein the transceiver is further configured to transmit a channel with the reporting quantities indicating the hypothetical channel conditions.

9 . The UE of claim 8 , wherein:

the second information includes offset values to actual transmission powers of the RSs, and

the offset values are separately signaled and applied to respective RSs or commonly signaled and applied to all of the RSs related to the first information.

10 . The UE of claim 8 , wherein the reporting quantities indicate information related to a hypothetical BF or RLF and include at least one of:

a reference signal received power (RSRP),

a reference signal received quality (RSRQ),

a signal to interference and noise ratio (SINR), and

a block error rate (BLER) of a hypothetical physical downlink control channel (PDCCH) reception.

11 . The UE of claim 8 , wherein the reporting quantities indicate an occurrence of a BF instance or an RLF instance at the hypothetical adaptation of transmission powers of the RSs.

12 . The UE of claim 8 , wherein the transceiver is further configured to:

receive third information related to determination of the reporting quantities including one or more conditions for transmitting the reporting quantities indicating a hypothetical BF or RLF, and

transmit the channel with the reporting quantities indicating the hypothetical BF or RLF at the hypothetical adaptation of transmission powers of the RSs satisfying the one or more conditions.
