Abstract: A data transmitting method is presented for implementing early acknowledgement of receipt of uplink data and new transmission scheduling. The data transmitting method for user equipment includes: receiving scheduling information from a base station; transmitting first uplink data to the base station by an initial number of retransmissions; monitoring, in a first search space, whether a first acknowledgement signal for uplink data has been received from the base station, and meanwhile, monitoring, in a second search space, whether a second acknowledgement signal for uplink data has been received from the base station; in the case that the first acknowledgement signal has been received in the first search space, stopping retransmitting the first uplink data; and in the case that the second acknowledgment signal has been received in the second search space, stopping retransmitting the first uplink data, and starting to transmit the second uplink data to the base station.

Abstract: Provided are wireless communication methods and corresponding base stations and user terminals. The wireless communication method performed by the base station includes generating indication information indicating a support capability of the base station for user terminals of different heights and/or types; and transmitting the indication information to user terminals within a cell managed by the base station. The wireless communication method performed by the user terminal includes receiving indication information indicating a support capability of a base station for user terminals of different heights and/or types; and selecting a portion of information that matches its own height and/or type from the indication information.

Abstract: The present invention provides a method for allowing user terminal to acquire information about paging physical resource blocks (PRBs), a method of allowing a base station to indicate information about paging PRBs to UE, a method of allowing UE to determine allocation of paging PRBs, a method of allowing a base station to allocate paging PRBs, a base station and UE. The above method of allowing user terminal to acquire information about paging physical resource blocks (PRBs) includes detecting an anchor PRB, reading information carried by the anchor PRB, and acquiring information about the non-anchor paging PRBs associated with the anchor PRB based on the information carried by the anchor PRB. By this method, non-anchor paging PRBs can be specified to the UE.

Abstract: The present invention is designed so that, even when communication is made using a plurality of transmission time intervals (TTIs), scheduling requests are transmitted adequately. According to one aspect of the present invention, a user terminal has a transmitting/receiving section that transmits and/or receives using a plurality of transmission time intervals (TTIs) of different durations, and a control section that determines a resource to use to transmit a scheduling request (SR) based on at least one of a first TTI and a second TTI having a shorter TTI duration than the first TTI.
