FIELD: data transmission.
SUBSTANCE: invention relates to a method of determining transmission direction information used in user equipment. The method includes: obtaining direction configuration information dynamically transmitted by the base station, wherein the direction configuration information indicates the transmission direction information of the information transmission resource; determining according to the direction configuration information whether there is no direction indication information for the information transmission base unit, or determining according to the direction configuration information whether at least two instances of direction indication information are present for the information transmission base unit and whether said at least two instances of the direction indication information correspond with each other; if there is no direction indication information for the information transmission base unit or there are at least two instances of direction indication information not corresponding with each other, determining such information transmission base unit as a target information transmission unit with unidentified direction indication; determining transmission direction information for the target information transmission unit following one of the described methods.
EFFECT: provided is flexibility of transmission resource configuration of the system.
