  • Publication number: 20210105716
    Abstract: A method of dynamically adapt to a minimum applicable scheduling offset value for a UE operated with bandwidth part (BWP) and cross-slot scheduling in a mobile communication network is proposed. At higher layer (L2 RRC layer), the UE receives RRC configuration for a set of minimum applicable scheduling offset values (K0/K2) for downlink/uplink cross-slot scheduling. At lower layer (L1 physical layer), the UE dynamically determines an active minimum K0/K2 value for an active DL BWP or UL BWP based on 1) a one-bit DCI indicator over PDCCH; or based on 2) an active BWP change due to timeout.

    Abstract: A method of wireless communication of a UE is provided. The UE determines resources of a first PDSCH and resources of second at least one PDSCH on a cell, the first PDSCH being a unicast PDSCH specific to the UE. The UE determines that the first PDSCH overlaps with the second at least one PDSCH in a time domain.

  • Publication number: 20200351774
    Abstract: A UE receives a configuration specifying that a particular DCI format include a field indicating adaptation of cross-slot scheduling or same-slot scheduling. The UE determines whether a first down link control channel received in a first downlink slot in an active time of a discontinuous reception (DRX) cycle is in the particular DCI format. The UE determines whether the field of the first down link control channel indicates adaptation of cross-slot scheduling when the first down link control channel is in the particular DCI format. The UE enters into a power saving state during a second downlink slot in the active time of the DRX cycle when the field indicates adaptation of cross-slot scheduling and no data are scheduled to be transmitted to the UE during the second downlink slot. The second downlink slot is the first downlink slot or a slot subsequent to the first downlink slot.

    Abstract: Aspects of the disclosure further provide various apparatuses and methods for wireless communications. One apparatus includes processing circuitry that can determine a first transmission power for a first uplink transmission associated with the source cell and a second transmission power for a second uplink transmission associated with the target cell. When the first uplink transmission and the second uplink transmission overlap in time domain and a total power of the first transmission power and the second transmission power is above a first threshold, the processing circuitry reduces the first transmission power for the first uplink transmission to a third transmission power so that a total power of the second transmission power and the third transmission power is equal to or less than the first threshold. The processing circuitry performs the first uplink transmission at the third transmission power and the second uplink transmission at the second transmission power.

  • Patent number: 10785769
    Abstract: A method to improve the design of new radio physical downlink control channel (NR-PDCCH) transmission and to reduce the false alarm rate of NR-PDCCH blind decoding is proposed. The downlink control information (DCI) bits are carried by NR-PDCCH to be transmitted to UEs after CRC attachment, channel encoding, interleaving, and modulation. The proposed NR-PDCCH design is separated into two parts. In a first part, a UE-ID or RNTI is used to derive a CRC mask or a scrambling sequence for CRC attachment of the DCI bits. In a second part, a UE-specific ID is used to derive an interleaver before or after channel encoding of the DCI bits. If the interleaver is placed before channel encoding, it takes the form of a bit interleaver. If the interleaver is placed after channel encoding, it takes the form of a bit interleaver or a channel interleaver.
