摘要:
A modulation method and device for modulating transfer format combination indicator TFCI information, the method including: dividing equally original TFCI information in a unit of 2 bits in a transmission time interval TTI; extending the resultant respective parts of the TFCI information after the division to correspond to identifiers of one or more designated energy points in a preset constellation; and mapping the respective extended parts of the TFCI information to the corresponding energy points for modulating.

摘要:
A method and device for indicating data re-transmission when area switching in LTE system, wherein the method comprises the following steps: S_eNB sends PDCP-SDU CN report to T_eNB in order to announce PDCP-SDU SN received, and T_eNB announces PDCP-SDU SN received by S_eNB to UE. Thereby, UE would not re-transmit PDCP-SDU corresponding to received SN, which avoids re-transmission of useless PDCP-SDU, and saves radio resources comparing with prior solutions.
