Abstract: Aspects of the disclosure provide an electronic device and methods for determining energy efficiency of the electronic device that receives wireless communication service from a network. The electronic device includes processing circuitry. The processing circuitry is configured to determine an amount of data transmitted between the electronic device and the network over a duration. The processing circuitry is configured to determine energy consumption of the electronic device over the duration based on a power consumption model. Further, the processing circuitry is configured to calculate an energy efficiency indicator based on the amount of data transmitted and the energy consumption. In an example, the processing circuitry is configured to report the energy efficiency indicator to the network.

Abstract: A User Equipment (UE) including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a cell. The controller receives a System Information Block type1 (SIB1) comprising first configuration of a bandwidth size of an initial Downlink (DL) Bandwidth Part (BWP) from the cell via the wireless transceiver, and applies the first configuration for communication with the cell via the wireless transceiver in response to the UE in a Radio Resource Control (RRC) idle or inactive state successfully completing a random access procedure.

Abstract: Aspects of the disclosure can provide an apparatus and method for paging transmission including receiving, by a processing circuitry of a user equipment, a synchronization signal burst in a beamformed wireless communication system for downlink synchronization, and receiving at least a paging frame offset. The method can further include selecting at least a paging frame of a frame structure that has system frame number that satisfies a paging frame formula, and remapping the selected paging frame to location within the frame structure based on the paging frame offset value.

Abstract: Apparatus and methods are provided for on-demand SI request procedure. In one novel aspect, the RACH procedure is used for one-demand SI information updates through unicast. In one embodiment, the UE sends an embedded SI request message in Msg3 requesting one or more on-demand SI including a UE ID. The SI response and the information of the requested SI are included in the Msg4 or in a separate unicasted message. In another embodiment, one or more assistant information is included in Msg3 or are associated with the preamble in Msg1. In another novel aspect, the preamble of the Msg1 is associated with a group X of SIB. Upon detecting the failure of transmission of the SI request, the UE monitors and receives updated SI information of the whole group X through a broadcast channel.

Abstract: Apparatus and methods are provided for efficient bandwidth adaptation for wideband carrier. In one novel aspect, the UE starts a BWP timer upon detecting one or more BWP timer starting triggering events, resets the BWP timer upon detecting BWP resetting triggering events, and switches to the default BWP upon expiration of the BWP timer. The BWP timer starting triggering events comprises decoding a command to switch away from the default BWP, the detection of end of DL data transmission in DRX mode. In another novel aspect, the UE only decodes the DCI indication for active BWP switching in the first three OFDM symbols of a subframe or a slot. In yet another novel aspect, when the SPS is configured for the serving cell for a UE with multiple BWPs, the SPS is configured for all the BWPs accordingly.

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 a radio bearer configuration. The UE also configures, based on the received radio bearer configuration, a radio bearer including a first logical channel on a first carrier and a second logical channel on a second carrier. The UE further determines whether to activate the radio bearer to perform duplication. In response to a determination to activate the radio bearer to perform duplication, the UE communicates a first packet on the first logical channel and communicates a duplicated first packet on the second logical channel.

Abstract: A method of adaptive transmission time interval (TTI) tuning based on TCP information is proposed. First, a procedure for TCP information delivery between eNB and TCP sender/TCP receiver is disclosed. The TCP information comprises TCP status, TCP congestion window (CWND) size, TCP round trip delay, TCP SS threshold, TCP index, and TCP event indication. Second, various methods for eNB to configure TTI with UE TCP information and/or buffer information are disclosed. A first method is saturation detection which includes buffer status based saturation detection and CWND based saturation detection. A second method is Greedy Buffer Clearing. A third method is TCP state based TTI selection method.

Abstract: A first network node receives downlink signaling from a second network node in a first occasion, received on a first carrier in a first time slot, and a second occasion, which is received either on the first carrier in a second time slot after the first time slot or on a second carrier in the first time slot or the second time slot. A MAC control element (CE) in the downlink signaling received in the first and second occasions contain a first timing padding value and a second timing padding value, respectively. A predetermined time slot is equally indicated by the first time slot plus the first timing padding value as well as by the second time slot plus the second timing padding value. The first network node effects one or more configurations in the predetermined time slot responsive to receiving the downlink signaling in the first and second occasions.

Abstract: A method of system information (SI) acquisition with reduced signaling overhead is proposed. To reduce SI broadcast overhead, the quantity of periodic SI broadcast and the frequency of on-demand SI acquisition need to be reduced. In order to reduce the quantity of periodic SI broadcasting, on-demand SI delivery is enabled. With on-demand SI delivery, signaling overhead is proportional to the frequency of SI acquisition. From the network side, the base stations proactively provide SI delivery options and delivers SI over unicast or scheduled broadcast. From the UE side, UE determines how to acquire SI, i.e., by listening to broadcast or by sending an on-demand request via existing procedures such as a random-access procedure over a random-access channel (RACH).
