Abstract: Carrier aggregation and dual connectivity leverage multiple component carriers to increase the effective bandwidth available to a given UE. Embodiments of this disclosure extend the concept of carrier aggregation and dual connectivity by using a physical component carrier and one or more virtual component carriers from one physical component carrier group and/or one virtual component carrier group, which have the same carrier frequency and carrier bandwidth as the physical component carrier, to transmit data streams to a user equipment. Data streams communicated over the physical component carrier and the virtual component carrier(s) may be orthogonal in the time domain or code domain. Alternatively, data streams communicated over the physical component carrier and the virtual component carrier(s) may be non-orthogonal, in which case the UE may need to decode the respective data streams using non-orthogonal signal processing techniques.

Abstract: A random access method and an apparatus are described that provide improved transmission efficiency of a response message based on the response message scheduled by a plurality of PDCCHs. A terminal device receives a first control channel resource set used to monitor a common physical downlink control channel PDCCH and a second control channel resource set used to monitor a specific PDCCH that are sent by a network device. The terminal device sends a first message to the network device, and the terminal device monitors a first search space corresponding to the first control channel resource set and a second search space corresponding to the second control channel resource set to receive at least one of the common PDCCH and the specific PDCCH, to schedule a PDSCH that carries a response message of the first message.

Abstract: METHOD FOR DOWNLINK CONTROL CHANNEL DESIGN
Embodiments of this disclosure improve the reliability of blind decoding when beamforming is used by having a user equipment (UE) receive a single downlink control information (DCI) message with different transmission and/or reception parameters. In some embodiments, a UE receives more than one set of configuration parameters, where any two sets of configuration parameters out of the more than one set of configuration parameters have at least one different parameter. The UE may receive two sets of configuration parameters each having a different transmission modes, but the same search space type. Additional examples are also provided.-

Abstract: Embodiments of this application disclose a power control method, and belong to the field of wireless communications technologies. The method includes: receiving, by a terminal device, signaling from a radio access network device; learning, by the terminal device based on the signaling, of a slot of power control information required by the terminal device to perform uplink sending; and obtaining, by the terminal device in the slot of the power control information required for uplink sending, the power control information required for uplink sending, so that the terminal device dynamically obtains uplink power control information of the terminal device without being based on a static uplink-downlink subframe configuration in the prior art.

Abstract: A resource determining method is provided. The method includes: determining a time domain position and a resource unit type of a first time domain resource unit based on first configuration information; determining a time domain position of a second time domain resource unit based on the time domain position of the first time domain resource unit, where the time domain position of the second time domain resource unit is at a time domain position which is different from the time domain position of the first time domain resource unit and is within a preset time period; and receiving second configuration information from a network-side device, and determining a resource unit type of the second time domain resource unit based on the second configuration information. Thus, subframe types of various subframes in D-TDD can be determined.

Abstract: Embodiments of the present application pertain to control information for scheduling a transmission resource for downlink and uplink communications between one or more TRP and one or more UE. One Physical Downlink Control Channel (PDCCH) for DL control information transmission is assumed to carry at least one assignment or scheduling information block for at least one Physical Downlink Shared Channel (PDSCH) for DL data transmission or for at least one Physical Uplink Shared Channel (PUSCH) for UL data transmission. Embodiments of the present application provide methods of providing configuration information that can be used by a user equipment (UE) to determine transmission mode for the PDSCH and PUSCH as well as information to determine where to monitor for the PDSCH, PUSCH and PUCCH information.
