Abstract
An apparatus receives, from a wireless network, a secondary cell (SCell) activation command. The apparatus determines whether a target SCell is known. Based on a result of the determining, the apparatus performs one or more operations.
Claims17
A method, comprising:
- receiving, by a processor of an apparatus, from a wireless network a secondary cell (SCell) activation command;
- determining, by the processor, whether a target SCell is known;
- and
- performing, by the processor, one or more operations based on a result of the determining,
- wherein the determining of whether the target SCell is known comprises:
- determining that the target SCell is known responsive to a Layer 1 (L1) or Layer 3 (L3) reference signal received power (RSRP) report having been transmitted before the receiving of the SCell activation command by no more than a predefined duration (X);
- and
- determining that the target SCell is unknown responsive to the L1 or L3 RSRP report having not been transmitted or having been transmitted before the receiving of the SCell activation command by more than the predefined duration (X).
5 more elements
A method, comprising:
- transmitting, by a processor of an apparatus, to a wireless network a Layer 1 (L1) or Layer 3 (L3) reference signal received power (RSRP) report;
- receiving, by the processor, from the wireless network a secondary cell (SCell) activation command;
- receiving, by the processor, from the wireless network a transmission configuration indication (TCI) state activation command;
- and
- performing, by the processor, one or more operations responsive to the TCI state activation command being received after a duration (D) later than receiving the SCell activation command,
- wherein the receiving of the SCell activation command comprises receiving the SCell activation command within a second predefined duration (X) after transmitting the L1 or L3 RSRP report.
3 more elements
A method, comprising:
- transmitting, by a processor of an apparatus, to a wireless network a Layer 1 (L1) or Layer 3 (L3) reference signal received power (RSRP) report;
- receiving, by the processor, from the wireless network a secondary cell (SCell) activation command;
- receiving, by the processor, from the wireless network a transmission configuration indication (TCI) state activation command;
- and
- performing, by the processor, one or more operations responsive to the TCI state activation command being received after a duration (D) later than receiving the SCell activation command,
- wherein the performing of the one or more operations comprises:
- transmitting to the wireless network a channel state information (CSI) report;
- and
- applying the TCI state activation command,
- wherein the transmitting of the CSI report comprises transmitting the CSI report within an extended duration (Y′) after the receiving of the SCell activation command, and
- wherein the extended duration (Y′) is equal to a SCell activation delay (Y) plus the duration (D).
