Abstract: A method of wireless communication of a UE is provided. The UE determines a first value of one or more parameters indicating a reception condition of a channel from a base station. The UE determines to adjust channel state information (CSI) reporting based on the first value. The UE transmits UE-assisted information to the base station, and the UE-assisted information includes the one or more parameters or an indication of an adjusted reporting schedule of the CSI reporting. Alternatively, the UE refrains from transmitting a CSI report scheduled in accordance with an existing reporting schedule of the CSI reporting.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, a configuration specifying one or more power profiles of the UE. Each of the power profile includes a predetermined value of at least one operational parameter that, while adopted by the UE when the configuration is applied, affects a power consumption of the UE. The UE operates in accordance with a first power profile of the one or more power profiles. The UE determines that a trigger event has occurred. The UE switches to operate in accordance with a second power profile of the one or more power profiles.

In one novel aspect, the UE configured with multiple BWPs is configured with a plurality of UE states each associated with one or more configured BWP, and transitions to or from a power-saving state upon detecting one or more transitioning conditions. In one embodiment, the UE transitions to and from the power-saving state upon detecting a switching signal. In another novel aspect, the UE with multiple BWPs is further configured with a leader BWP set for a leader cell, and one or more sets of follower BWP sets for corresponding follower cells of the UE, bundles each leader cell UE state with corresponding follower UE state for each follower cell, and transitions from a corresponding follower cell power saving state automatically for the one or more follower cells upon the leader cell UE state transition.

Abstract: Apparatus and methods are provided for configured PUSCH opportunities with activation. In one novel aspect, a plurality of PUSCH opportunities and one or more activation opportunities are configured. The UE triggers one or more PUSCH opportunities for UL data transmission using an activation signal transmitted at one of the configured activation opportunities and transmits UL data on one or more PUSCH resources configured by the PUSCH opportunities associated with the activation opportunity on which the activation signal is transmitted. In one embodiment, the activation signal is a L1 signal or a scheduling request. The dynamic scheduling may or may not be used for data transmission. In one embodiment, the configured PUSCH opportunities are available for data transmission by dynamic scheduling until detecting one or more disabling conditions. In another embodiment, the configured PUSCH opportunities are not available for data transmission until detecting one or more enabling conditions.

Abstract: Various solutions for transmission resource allocation with respect to user equipment (UE) and network apparatus in mobile communications are described. A UE may receive control information from a network apparatus. The UE may turn on a radio frequency (RF) transceiver of the UE in a part of a transmission time interval (TTI) to receive downlink data in an event that the control information indicates that the downlink data is scheduled in the TTI. The downlink data is scheduled in a part of the TTI but not in any other time interval. The time duration of the TTI may comprise 14 orthogonal frequency-division multiplexing (OFDM) symbols and the part of the TTI may be configured as a mini-slot with time duration less than 14 OFDM symbols.

Abstract: Aspects of the disclosure provide a method for accelerating a decoding process. The method includes receiving first bit reliability values (BRVs) of a first codeword corresponding to a first bit sequence of an information block, receiving second BRVs of a second codeword corresponding to a second bit sequence of the information block, aggregating respective first BRVs and second BRVs into an aggregated. BRV for each static code bit of the second codeword, and decoding the second codeword to recover the second bit sequence of the information block using the aggregated BRVs of each static code bit of the second codeword.

Abstract: Concepts and examples pertaining to improved design for communication systems suffering burst error are described. A processor of a user equipment (UE) receives data over a data channel. The processor also receives an indication that at least a portion of the data channel is subject to interference from one or more interfering signals. The processor either de-weights one or more affected resource elements in the data according to the indication to mitigate impact by the interference or processes the data without considering the indication

Abstract: Narrowband downlink control channel (NB-PDCCH) design for Narrowband Internet of Thing (IoT) devices is proposed. In one novel aspect, NB-PDCCH spans both first and second slots in the region of legacy physical downlink shared channel (PDSCH). A plurality of physical resource blocks (PRBs) is allocated for NB-PDCCH transmission that carry downlink control information (DCI). Furthermore, each NB-IoT device can be configured with nPRB PRB pairs for NB-PDCCH transmission (e.g., nPRB=1, 2, 4, or 8), and an NB-PDCCH transmission time interval (TTI) is composed by nPRB subframes. An NB-PDCCH is encoded and occupies multiple narrowband control channel elements (NCCEs) based on aggregation level. In a preferred embodiment, each PRB pair for NB-PDCCH occupies two NCCEs.
