Abstract: A method and apparatus for improving beam finding in a wireless communication system. In one embodiment, the method includes the base station detecting a first preamble transmission from a UE on a beam. The method also includes the base station examining extra transmissions to detect whether there are other beams which can be used to communicate with the UE. The method further includes the base station considering a beam set of the UE is complete if a rule is fulfilled, wherein the beam set of the UE includes beam(s) through which the UE could communicate with the base station.

Abstract: Methods and apparatuses for triggering a power headroom report for beam operation in a wireless communication system are disclosed herein. In one method, a user equipment (UE) uses multiple beams for transmission. The UEtriggers a power headroom report due to a change of a pathloss being larger than a threshold, wherein the pathloss is associated with a specific beam or a set of beams.

Abstract: A method and apparatus are disclosed from the perspective of a network. In one embodiment, the method includes the network configuring a UE (User Equipment) with a plurality of DL (Downlink) BWPs (Bandwidth Parts) of a serving cell, wherein the plurality of DL BWPs comprises a first DL BWP with a first SCS (Sub-Carrier Spacing) and a second DL BWP with a second SCS, wherein the second SCS is different from the first SCS. The method further includes the network configuring the UE with a first monitoring occasion for indicating slot format indication (SFI) in the first DL BWP by indicating a first slot offset and a first slot periodicity. The method also includes the network configuring the UE with a second monitoring occasion for indicating slot format indication (SFI) in the second DL BWP by indicating a second slot offset, and a second slot periodicity, wherein the network is not allowed to indicate the second slot offset and the second slot periodicity such that a time period containing a number of consecutive slots associated with a slot format in the combination of slot formats indicated by a SFI index in the second monitoring occasion does not align slot boundary of a slot with the first SCS, and wherein the number is the ratio of the second SCS to the first SCS.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE receives an indication from a base station, wherein the indication is indicative of monitoring a power saving signal in one or more monitoring occasions and at least one monitoring occasion of the one or more monitoring occasions is associated with a Discontinuous Reception (DRX) ON duration and is within Active Time associated with the UE. The UE does not monitor and/or skips monitoring the power saving signal in the at least one monitoring occasion. The UE monitors Physical Downlink Control Channel (PDCCH) during the DRX ON duration.

Abstract: Methods and apparatuses estimating pathloss of PUSCH in a wireless communication system are disclosed herein. In one method, the UE receives a first configuration of a first serving cell and a second serving cell, wherein the second serving cell is a pathloss reference for the first serving cell. The UE receives a second configuration of multiple downlink bandwidth parts of the second serving cell, wherein a downlink bandwidth part among the multiple downlink bandwidth parts is an active downlink bandwidth part. The UE estimates (or derives) a pathloss for an uplink transmission in an uplink bandwidth part of the first serving cell based on a reference signal in the downlink bandwidth part.
