Abstract: A paging method is disclosed. In an embodiment a method for paging monitoring implemented by a user equipment (UE) includes hashing an identity of the UE to determine a paging frame in which a page is to be sent to the UE and to determine a position of an indicator in a bitmap to be sent to the UE, wherein a value of the indicator indicates whether a page message associated with a paging group to which the UE belongs is transmitted in a current paging cycle, selecting a first downlink beamformed beam from a plurality of beams within the determined paging frame, receiving the bitmap from the first downlink beam and determining that the value of the indicator indicates that the page message is transmitted in the current paging cycle and, based thereon, receiving and decoding the page message to determine whether the UE is being paged.

Abstract: A method of link adaptation is described including establishing, using a first serving point, a multi-user full duplex mode wherein the multi-user full duplex mode enables a downlink to a first wireless device and an uplink from a second wireless device. The first serving point requests from the first wireless device a first channel quality indicator indicating channel quality between the serving point and the first wireless device in a full duplex time period and a second channel quality indicator indicating channel quality between the serving point and the first wireless device in non-full duplex time period. The full duplex mode is evaluated using the first and second channel quality indicators. At least one parameter of the full duplex mode is adjusted based on the evaluating.
