FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a wireless communication system and is intended to provide improved communication between user equipment and a base station in a communication network. User equipment (605) is configured to communicate with a base station (603) according to the category of the user equipment, selected from at least two user equipment categories. The user equipment (605) selects one of the at least two user equipment categories if information indicating the one of the at least two user equipment categories is received from the base station (603). The user equipment (605) selects a default of the at least two user equipment categories if no information indicating which of the at least two user equipment categories is received from the base station (603). The user equipment (605) determines a soft buffer size according to the selected user equipment category. The user equipment (605) communicates with the base station (603) according to the selected user equipment category and applying the determined soft buffer size.
EFFECT: improved communication.
