Abstract: An incremental scheduling scheme is proposed in a wireless communication system with beamforming. In an initial stage (stage-1), coarse scheduling plan is granted via control beam transmission. In a second stage (stage-2), fine scheduling plan is granted via dedicated beam transmission. Such incremental scheduling scheme provides load balancing for overhead channels on control/dedicated beams via stage-2 scheduling. It utilizes dedicated beam transmission that is more resource efficient and more UE-specific. Furthermore, it provides UE natural power-saving opportunities via stage-1 scheduling.

Abstract: A method of control signaling in a beamforming system is proposed. A user equipment (UE) receives control beam transmission from a base station using a set of control beams in a beamforming network. Each control beam comprises a set of DL control resource blocks, a set of UL control resource blocks, and an associated set of beamforming weights. The UE selects a control beam for establishing a connection with the base station. The UE then performs random access with the base station using the selected control beam.

Abstract: A method of maximum output power configuration with UE preference in carrier aggregation is provided. A UE configures multiple component carriers (CCs) with carrier aggregation for communicating with a serving base station in a mobile communication network. The UE determines channel condition of multiple serving cells over the corresponding multiple CCs. The UE then determines maximum output power for each CC based at least in part on the corresponding channel condition of each CC. Finally, the UE transmits power headroom report (PHR) for each CC to the serving base station, wherein the PHR is calculated based on the determined maximum output power. As a result, the reported PH information is channel condition dependent, which can be used by eNB for facilitating better transmission scheduling.

Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. The UE later enters RRC_IDLE mode and releases a radio bearer of the unicast EPS bearer while keep monitoring the multicast MBMS bearer for the DL multicast traffic.

Abstract: Various solutions for tiered channel information feedback with respect to user equipment and network apparatus in mobile communications are described. An apparatus may determine a first tier channel state information (CSI) based on a first reference signal resource measurement. The apparatus may report the first tier CSI to a network node. The apparatus may determine a second tier CSI based on the first tier CSI and based on a second reference signal resource measurement. The apparatus may report the second tier CSI to the network node. The second tier CSI may be different from the first tier CSI.

Abstract: Aspects of the disclosure provide an electronic device including a transceiver and processing circuitry. The transceiver can be configured to wirelessly receive at least one signal from a network including a first cell. The at least one signal can indicate a link quality of a wireless link formed between the electronic device and the base station in a first cell. The processing circuitry can be configured to determine whether beam failure occurs on the first cell based on at least one signal quality of the at least one signal. When the beam failure is determined to occur on the first cell, the processing circuitry can be configured to report information of the first cell to the network indicating the beam failure on the first cell.

Abstract: In one novel aspect, configurations for PDCCH transmission and reception with multiple transmission points are provided. The UE configures a PDCCH associated with a CORSET comprising multiple CCEs, partitions the CORSET into multiple TCI-state sets, wherein each TCI state set includes multiple CCE groups associated with corresponding TCI-state, which corresponds to a source TRP, activates one TCI state set, and receives DCI via the PDCCH, wherein the PDCCH is transmitted from at least the first source TRP and the second source TRP, and wherein each source TRP transmits corresponding portion of DCI data mapping to the corresponding first and second CCE group. The CORSET is partitioned in FDM or TDM way. In another novel aspect, a first and a second PDCCH associated with a first and a second TRP are configured for repetition transmission. The second PDCCH configuration is dependent upon the first PDCCH configuration.

Abstract: A method of default Quasi-Co-Location (QCL) assumption for Physical Downlink Shared Channel (PDSCH) reception in NR network is proposed. When PDSCH is scheduled by a DCI over PDCCH after a Scheduling Offset, the spatial RX filter for the PDSCH reception can be determined according to a QCL indication conveyed by the DCI. When the Scheduling Offset for PDSCH reception scheduled by DCI is less than a time duration, then a default QCL assumption is applied. UE assumes that the DMRS ports of PDSCH of a serving cell are QCLed with the RS(s) with respect to QCL parameter(s) used for PDCCH QCL indication of a CORESET. The CORESET is associated with a UE-monitored search space in the latest slot with the lowest CORESET-IF on an active BWP on the serving cell.

Abstract: Aspects of the disclosure provide a method for reception of simultaneously transmitted downlink channels having different spatial quasi-co-location (sQCL) assumptions. The method can include receiving a configuration specifying a control resource set (CORESET) monitoring occasion of a first physical downlink control channel (PDCCH) at a user equipment (UE), receiving a second PDCCH scheduling or activating transmission of a physical downlink shared channel (PDSCH) at the UE, determining whether the PDSCH overlaps the first PDCCH in time domain, determining whether a first spatial quasi-co-location (sQCL) assumption for reception of the first PDCCH and a second sQCL assumption for reception of the PDSCH are different, and prioritizing the reception of the first PDCCH when the PDSCH overlaps the first PDCCH in time domain and the first and second sQCL assumptions are different.

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 determines that a random access event has occurred. The UE detects one or more down-link reference signals that are UE-specifically configured or predefined. The UE further selects a first message that is associated with a first down-link reference signal of the one or more down-link reference signals, the first down-link reference signal being quasi-colocated with a first DMRS of a serving control channel of the UE. The UE sends the first message to a base station to request a random access to the base station.
