==DEFAULT BEAMS FOR PDSCH, CSI-RS, PUCCH AND SRS - A simplified explanation of the abstract==


*This abstract for appeared for US patent application  number 17598012 Titled 'DEFAULT BEAMS FOR PDSCH, CSI-RS, PUCCH AND SRS'

==Simplified Explanation==

The abstract describes a method and device for configuring default beams in wireless communication. The User Equipment (UE) receives configuration information from a base station to set up a default beam for the physical downlink shared channel (PDSCH). This default beam is used when the time difference between receiving downlink control information (DCI) in the scheduling physical downlink control channel (PDCCH) and the corresponding PDSCH is below a certain threshold. The UE configures the default beam based on the received information and a monitored control resource set (CORESET) with the lowest CORESET identifier (ID) from a set of CORESETs in the same bandwidth part (BWP). The UE then receives a transmission using the default beam.


==Original Abstract Submitted==

A method and apparatus configuring default beams are described. In some embodiments, the method of wireless communication at a User Equipment (UE) comprises: receiving, from a base station, configuration information for configuring a default beam for the physical downlink shared channel (PDSCH) to use on condition that an offset between reception of downlink control information (DCI) in the scheduling physical downlink control channel (PDCCH) and corresponding PDSCH is less than a threshold and at least one Transmission Configuration Indicator (ICI) states includes spatial receiving parameters for configuring a quasi-co-location; configuring, by the UE, a default beam configuration for the PDSCH based on the configuration information and a monitored control resource set (CORESET) with a lowest CORESET identifier (ID) from among a set of CORESETs in a latest slot in a same bandwidth part (BWP), wherein at least one CORSET of the set of CORESETs includes more than one TCI state; and receiving a transmission using the default beam.
