Abstract: A method of UE power profile adaptation to traffic and UE power consumption characteristics based on power profile is proposed. In one preferred embodiment, hybrid of bandwidth part (BWP) and power profile is proposed. UE is configured with multiple BWPs and each BWP includes a set of power profiles. Two types of adaptation triggering can be used, a first type of trigger is based on power saving signals sent from the network, and the second type of trigger is based on timers. When the traffic characteristic for UE changes, the network can send a power saving signal to UE to trigger power profile adaptation, e.g., BWP+power profile switching. When traffic has been digested and becomes sporadic, then power profile adaptation can be triggered based on timers, e.g., a timer for BWP adaptation and another timer for power profile adaptation.

Abstract: Aspects of the disclosure provide a method for physical broadcast channel (PBCH) processing at a base station (BS) in a wireless communication system. The method can include performing a channel coding process to generate encoded PBCH data at the BS. The encoded PBCH data is to be carried in a synchronization signal block (SS block) having an SS block index (SBI), and transmitted from a cell having a cell ID. The method can further include performing a second scrambling over the encoded PBCH data with a second scrambling code determined based on the cell ID and the SBI to generate second scrambled PBCH data.

Abstract: Aspects of the disclosure provide an electronic device including processing circuitry and a method for beam management (BM) with power saving. The processing circuitry can receive a reference signal from a network via a serving beam pair used for downlink (DL) transmission between the network and an electronic device. The serving beam pair can include a serving transmission (Tx) beam transmitted from the network and a serving reception (Rx) beam received by the electronic device. The processing circuitry can determine a signal quality of the reference signal. When the signal quality is determined to satisfy a power saving condition, the processing circuitry can reduce beam measurements in the BM for beam pairs including Tx beams transmitted from the network and respective Rx beams received by the electronic device. The beam pairs can include the serving beam pair and one or more candidate beam pairs.

Abstract: A UE receives one or more modulation symbols on one or more resource elements prior to an ON duration in a particular DRX cycle in RRC connected mode. The one or more resource elements are allocated to carry a wake-up signal. The UE performs a blind detection of the wake-up signal on the one or more modulation symbols in accordance with a DCI format and a group identifier identifying a group of UEs including the UE. The wake-up signal includes an indication that indicates whether one or more UEs of the group of UEs should monitor a down link control channel in the ON duration. The UE determines whether to operate in a normal state and monitor a down link control channel in the ON duration based on the wake-up signal when the wake-up signal is detected.

Abstract: A UE in a wireless network performs RRM measurements according to power saving schemes. The UE receives Synchronization Signal Blocks (SSBs), which are broadcast periodically from a base station to a cell served by the base station, and receives additional signal blocks transmitted periodically from the base station. The additional signal blocks and the SSBs use different time-and-frequency resources. The UE performs an RRM measurement according to information received within an RRM measurement window including at least one of the additional signal blocks and a corresponding one of the SSBs. Additionally or alternatively, the UE performs RRM measurements on SSBs with a first cycle period equal to a Discontinuous Reception (DRX) cycle period. In response to an indication that a predefined condition for the RRM measurements is satisfied, the UE performs the RRM measurements with a second cycle period which is at least two times of the first cycle period.

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, at the UE, a dormant BWP configuration indicating that a first BWP on which the UE operates in a dormancy behavior, the first BWP being on a first secondary cell established between the UE and a base station. The UE receives, on a primary cell established between the UE and the base station, a first indication for transitioning to operating in the dormancy behavior. The UE operates in the dormancy behavior on the first BWP in accordance with the first indication.

Abstract: Techniques and examples of hybrid automatic repeat request (HARQ) buffer size design for communication systems are described. A user equipment (UE) communicates with a serving cell of a wireless network using a HARQ mechanism, with the communicating involving: (a) determining, by the processor, a respective size of each buffer of a plurality of buffers corresponding to a plurality of HARQ processes on a per-HARQ process basis; and (b) storing, by the processor, respective information in each buffer of the plurality of buffers for a corresponding HARQ process among the plurality of HARQ processes.

Abstract: Apparatus and methods are provided for polar code sub-block interleaving and bit selection. In one novel aspect, middle-part interlaced sub-block interleaving is provided for polar code interleaving. In one embodiment, the middle part of the polar code is interlaced and generates the interleaved polar code. In another embodiment, the lower part and the upper part are also sub-block interleaved with the middle-part interlaced method. In another novel, rate-dependent unified bit selection is provided. The bit selection is categorized into three operation categories of repetition, puncturing and the shortening. Each category follows unified bit selection rule with different categories differ only in the access scheme. In one embodiment, the circular buffer is used for bit selection.
