Abstract: A base station provides downlink feedback information (DFI) to a user equipment (UE) in a wireless network. The base station generates hybrid automatic repeat request (HARQ) acknowledgment (HARQ-ACK) information in a downlink control information (DCI) payload for each HARQ process associated with uplink transmission from the UE to the base station. The base station sets a DFI flag in the DCI payload to a predetermined value. The base station generates error detection bits based on the DCI payload, and sends DCI to the UE. The DCI includes the DCI payload and the error detection bits scrambled with a configured scheduling radio network temporary identifier (CS-RNTI).

Abstract: Aspects of the disclosure further provide an apparatus and a method for wireless communication. The apparatus includes processing circuitry that receives, from a base station (BS), a downlink (DL) grant scheduling an uplink (UL) transmission to the BS. The DL grant indicates a first type of channel access procedure for the UL transmission. The processing circuitry performs a channel access procedure for the UL transmission according to the first type of channel access procedure indicated by the DL grant.

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, on an unlicensed carrier and from a base station, a downlink signal including Listen-Before-Talk (LBT) parameters, the downlink signal being a non-physical layer signal. The UE performs an LBT operation based on the LBT parameters. The UE transmits an uplink signal to the base station when the LBT operation is successful.

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 detects a discovery reference signal on an unlicensed carrier. The UE determines timing information of a base station based on a location of the discovery reference signal in a transmission opportunity window of the base station. The UE determines resource elements of a down link control channel transmitted by the base station based on the timing information. The UE decodes the down link control channel.

Abstract: Various solutions for response of beam reporting with respect to user equipment and network node in mobile communications are described. An apparatus may transmit a report indicating at least one beam to a network node. The apparatus may receive a downlink control information (DCI) indicating an indicator from the network node within an effective duration corresponding to the report. The apparatus may determine whether the report is received or confirmed by the network node according to the indicator. The apparatus may perform a beam switching or a beam synchronization based on the at least one beam indicated in the report if the report is received or confirmed by the network node.

Abstract: A beam group reporting method is proposed. The network node may allocate a report configuration for the UE and transmit the allocated report configuration to the UE. The UE may perform the measurement based on the report configuration from the network node and determine at least one beam group based on a resource set associated with the report configuration and the measurement result. Each beam group may comprise two reference-signal (RS) resources respectively associating with different physical cell indexes (PCIs). Then, the UE may report a report comprising at least one beam group to the network node.

Abstract: A method of acquiring timing advance (TA) for neighbor cells to reduce latency and interruption for inter-cell mobility is proposed. A UE is configured with a set of active cells for fast cell-switching. To reduce handover interruption, UE performs early RACH for potential target cells and obtains the TA of the potential target cells. In one novel aspect, for overhead reduction, a single RACH preamble may be received by multiple cells. Using a single RACH preamble, UE acquires TA for multiple cells, aiming at reducing the interruption due to RACH during handover. In another novel aspect, UE reports DL reception timing difference between the serving cell and the neighbor cell, and then adjust the TA for the neighbor cell accordingly.

Abstract: Method and UE are provided for determining precoder of MIMO system. In particular, a BS can transmit at least one CSI-RS to the UE. The UE can receive the at least one CSI-RS, and estimate at least one covariance matrix of at least one downlink channel matrix according to the at least one CSI-RS at different times and frequencies. Then, the UE can transmit the at least one covariance matrix or at least one parameter associated with the least one covariance matrix to the BS for the BS to reconstruct at least one covariance matrix, and determine a precoder according to the at least one reconstructed covariance matrix.
