Abstract: A method for measuring beams includes determining a measurement period duration in accordance with periods of one or more periodic beam failure detection (BFD) reference signals (RSs) of a BFD RS set, wherein the BFD RSs of the one or more BFD RSs of the BFD RS set have a quasi-co-located (QCL) relationship with demodulation RSs (DMRSs) of PDCCH receptions monitored by a user equipment (UE), monitoring a subset of the one or more BFD RSs having the QCL relationship with the DMRSs of PDCCH receptions monitored by the UE that occur during a measurement period, and determining that measures of all BFD RSs in the subset of the one or more BFD RSs do not meet a specified threshold, and based thereon, reporting a beam failure (BF) instance.

Abstract: A data packet, that is to be transmitted in a dual connectivity (DC) or carrier aggregation (CA) based communications system, may include an indication to indicate whether the data packet is configured to be transmitted in a first frequency of a first carrier or a second frequency of a second carrier, and be transmitted, by a communication device, in the first frequency or the second frequency based on the indication. A data packet in the communications system may also be transmitted first in a first frequency higher than a second frequency, and then be retransmitted in the second frequency upon transmission failure of the data packet in the first frequency.

Abstract: A computer-implemented method includes sending, by an access node, to a user equipment (UE) configuration information for a beam quality reference signal (BQRS) that is associated with a discontinuous reception (DRX)-ON period used for sending a physical downlink control channel (PDCCH) to the UE, wherein the BQRS has a spatial quasi-collocated (QCL) relationship with either the PDCCH or a demodulation reference signal (DMRS) of the PDCCH. The method further includes sending, by the access node, the BQRS to the UE.
