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.

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: Example methods and apparatus for transmitting a signal transmission method and a device are disclosed. One method includes transmitting a signal based on a predefined transmission pattern by a communications device. The transmission pattern defines that a non-first downlink timing boundary in a downlink time domain unit is later than or earlier than a first downlink timing boundary is defined, or that an uplink timing boundary in an uplink time domain unit is earlier than or later than the first downlink timing boundary.

Abstract: Embodiments of the present invention disclose a base station, user equipment (UE), and a carrier scheduling indication method to resolve a problem that signaling overheads are relatively large. An embodiment method includes generating, by a processing unit, a carrier assignment indication (CAI) field of a current scheduled carrier according to scheduling statuses of all configured carriers, where the CAI field is used to indicate a total quantity of scheduled carriers in all the configured carriers and an accumulative index value M of the current scheduled carrier, and M represents that the current scheduled carrier is the Mth scheduled carrier from the 1st configured carrier to the current scheduled carrier; and sending, by a sending unit, downlink control information digital control information (DCI), by carrying the CAI field generated by the processing unit to the DCI, to UE by using the current scheduled carrier.

Abstract: The present invention relates to the field of wireless communications, and in particular, to a transmit power control technology in a wireless communications system. In a transmit power control method, user equipment performs transmit power compensation on subframes in different subframe sets by using different power compensation amounts, and sends data in the subframes by using uplink transmit powers on which the transmit power compensation has been performed. According to the solution provided in this application, smoothness of a signal-to-noise ratio of each uplink subframe can be ensured when a full-duplex technology is applied, and reception performance of the uplink subframe can further be ensured without causing excessively large signaling overheads.
