Abstract: A communications apparatus includes a radio transceiver transmitting or receiving wireless signals in a wireless network and a processor coupled to the radio transceiver. The processor is configured to perform operations comprising: transmitting pre-schedule mechanism assistance information to a network device in the wireless network for the network device to refer to for uplink (UL) resource allocation regarding a pre-schedule mechanism; receiving one or more uplink (UL) grants from the network device; and performing UL transmission to the network device responsive to receiving the one or more UL grants.

Abstract: The invention provides a method for antenna selectin of a user equipment (UE). The UE may comprise a plurality of antennas. The method may comprise calculating one or more quality evaluations respectively associated with one or more first antenna subsets, and selecting one of the one or more first antenna subsets according to the one or more quality evaluations. Each antenna subset may include one or more of the plurality of antennas. Each quality evaluation may be calculated under a condition that the antenna(s) included in the associated antenna subset is (are) used to communicate.

Abstract: Apparatus and methods are provided for determining AR filter coefficient and numbers of synchronization. In one novel aspect, the AR filter coefficient and times of synchronization are determined based on the temperatures of the oscillator. In one embodiment, the UE determines a temperature drift rate by collecting sets of temperatures before and after the UE in the sleep mode of the CDRX, generates one or more threshold look-up tables and performs an optimization selection based on the temperature drift rate and the one or more threshold of look-up tables, wherein the optimization selection comprising selecting an alpha coefficient and a number of subframes for synchronization. In another embodiment, the optimization selection is further determined based on a subcarrier spacing, and a channel type of being a static channel type and a fading channel type. The UE further performs an on-the-fly oscillator S-curve calibration based on the set of temperatures.

Abstract: Apparatus and methods are provided for determining UE appropriate states by traffic type detection. In one novel aspect, a UE traffic type is determined based on a plurality of UE metrics. One or more UE settings for transmission and/or reception are adjusted based on the determined UE traffic type. The UE traffic type determination procedure and UE configuration adjustment procedure are iterated to balance performance and power saving. In one embodiment, the UE collects a plurality of UE metrics for a UE traffic profile matrix, wherein the UE traffic profile matrix is used to determine a plurality of UE traffic types based on the plurality of UE metrics. The UE determines a real-time UE traffic type based on the collected UE metrics using the UE traffic profile matrix and adjusts a set of UE configurations based on the UE traffic type when one or more predefined conditions are met.
