Abstract: A method for determining and configuring a resource used for transmitting downlink data, a terminal and a base station: the base station configures, for each terminal, resource collections or resource collection subgroups used for receiving downlink data, and then the base station notifies the terminal, by means of an explicit signaling, whether all of the resource collections or each resource collection of the configured resource collections are available, or whether all of resource collection subgroups or each resource collection subgroup of the resource collection subgroups are available, thus allowing the terminal to determine, according to the notification, the time-frequency resource position of a resource used to receive downlink data, so that the terminal may carry out rate matching on the determined resource.

Abstract: Disclosed are a transmission method, a terminal, and a base station, for a base station cannot perform accurate uplink scheduling for a scheduling request (SR) of a terminal due to that there is no explicit solution for how to distinguish which SR in a plurality of SR configuration is transmitted simultaneously with other UCIs. In the transmission method for distinguishing a plurality of SR configurations provided by embodiments of the present disclosure, the terminal cascades an M-bit SR with a first UCI and simultaneously transmits same, and M-bit SR information is used for indicating SR states of the plurality of SR configurations of the terminal, ensuring that a base station performs correct uplink scheduling on the terminal.

Abstract: The present application discloses a method and an apparatus for transmitting uplink control information (UCI), to resolve the issue of repeated transmissions of UCI in the prior art. In an embodiment of the present application, a terminal determines a bit sequence of coded UCI of a first transmission, the UCI being repeatedly transmitted on a PUCCH, and the terminal transmits the bit sequence of the coded UCI in a determined uplink channel in each subsequent retransmission of the UCI. A network side apparatus uses the same method to determine a bit sequence of coded UCI of a first transmission, and receives, via a determined uplink channel, a repeatedly transmitted bit sequence of the coded UCI. In the embodiments of the present application, a bit sequence of coded UCI is determined according to a channel of the UCI in a first transmission time slot.

Abstract: The present application discloses methods and devices for determining a downlink resource set and sending resource position information, and particularly relates to a method for determining, by a terminal, a downlink control channel resource set, a method for sending, by a base station, a position related to a downlink control channel resource set, and related devices. A terminal obtains, in a predefined manner and/or by receiving a notification of a base station, a frequency domain position and a time domain position of a downlink control channel resource set corresponding to the terminal, so as to determine that the downlink control channel resource set corresponding to the terminal is a third downlink control channel resource set. The base station transmits a common downlink control channel and/or a terminal-dedicated downlink control channel on the frequency domain and time domain positions of the downlink control channel resource set determined by the terminal.
