    摘要: An uplink transmission method and an uplink transmission device are provided. The uplink transmission method includes: detecting an UL grant on a target time-domain resource and a target frequency-domain resource in a first time unit, the UL grant being to schedule one or more UEs to perform uplink transmission in a target time unit, a time unit having a predefined length of B1 subframes or B2 symbols, where B1 and B2 are each an integer greater than or equal to 1; acquiring scheduling information for the UE in the target time unit from the UL grant; and performing the uplink transmission on a time-domain resource and a frequency-domain resource scheduled in the target time unit in accordance with the scheduling information.

    摘要: Provided are an uplink control information transmitting method and receiving method, a terminal, a base station and an apparatus. The transmitting method includes: determining a first transmission resource for first uplink control information and second transmission resources for second uplink control information; and when the first transmission resource overlaps with at least two of the second transmission resources in the time domain, transmitting the first uplink control information and at least one of the second uplink control information simultaneously on the first transmission resource; wherein the at least one of the second uplink control information is the uplink control information carried on the at least two second transmission resources that overlap with the first transmission resource in the time domain.

    摘要: A random access method, a base station and a User Equipment (UE) are provided. A random access method applied to a base station side includes: receiving, by using a pre-configured first SubCarrier Spacing (SCS), a first random access preamble message transmitted by a UE when the base station instructs the UE to perform an initial access according to a contention-based random access mechanism; transmitting, by using a predetermined second SCS or a third SCS configured by a network, a first Random Access Response (RAR) message to the UE; receiving, by using a predetermined fourth SCS or a fifth SCS configured by the network, a first scheduling transmission message transmitted by the UE; and transmitting, by using a predetermined sixth SCS or a seventh SCS configured by the network, a first collision resolution message to the UE, to complete the initial access.
