FIELD: information technology.
SUBSTANCE: method and apparatus for transmitting and receiving a packet via high speed downlink packet access (HSDPA) are disclosed. At least one HSDPA medium access control (MAC-hs) service data unit (SDU) is segmented into a plurality of segments. MAC-hs protocol data units (PDU) are generated from the segments, wherein each MAC-hs PDU includes at least one segment. Each MAC-hs PDU may include one segment from a single MAC-hs SDU. The size of the segments may match the size of the MAC-hs PDU minus the size of the header of the MAC-hs PDU. The sizes of the segments may be determined based on the number of segments into which the MAC-hs SDU is segmented. Alternatively, each MAC-hs PDU may include a combination of segments from a plurality of MAC-hs SDU or a combination of at least one segment from one MAC-hs SDU and at least one whole MAC-hs SDU.
EFFECT: stability and reliability of the system.
