Abstract: Certain aspects of the present disclosure relate to methods and apparatus for radio link monitoring reference signal (RLM-RS) determination using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications from a UE generally includes determining resources to monitor for radio link monitoring (RLM) prior to being configured with resources to monitor for RLM after establishing a radio resource control (RRC) connection with a network, and performing RLM based on the determined resources.

Abstract: Apparatuses and methods of beam switching are presented. A beam switch message (BSM) is transmitted to a second device via a first beam set. The BSM includes a command to switch from communication via the first beam set to communication via a second beam set at a switch time. A response message is received from the second device via the first beam set. The response message indicates that the second device received the BSM. A communication is sent to the second device via the second beam set after the switch time if the response message is received.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for code rate selection for control channels. An exemplary method generally includes selecting, from a set of code rates, a code rate to be used to encode a stream of bits using a polar code, based on at least one of a downlink control channel aggregation size, an uplink control channel assignment, or a payload size of the stream of bits, encoding the stream of bits using the polar code and the selected code rate, and transmitting the encoded stream of bits.

Abstract: Certain aspects of the present disclosure provide techniques for supporting mobility management in a wireless communication system employing beams. A UE may receive, from a BS serving the UE, information regarding one or more reference beams and one or more event triggers associated with the one or more reference beams. The UE may detect one of the event triggers and may take one or more actions based, at least in part, on the detected event trigger.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to semi-persistent configuration of reference signals (RSs), such as measurement reference signals (MRSs) for beam refinement. An example method generally includes transmitting, to a user equipment (UE), a reference symbol (RS) configuration, wherein transmitting the RS configuration is independent of activating RS training for the UE, transmitting, to the UE, a message indicating an activation of RS training subsequent to transmitting the RS configuration, transmitting RSs to the UE periodically based on the RS configuration, and receiving, from the UE, measurement reports based on the transmitted RS.
