    摘要: A modulation mapping method and device for Discontinuous Transmission (DTX) bits are provided. The method includes: receiving binary symbols from a downlink physical channel; replacing symbol values of DTX bits in the binary symbols with symbol values of non-DTX bits, to obtained updated binary symbols; and performing modulation mapping on the updated binary symbols. Using the DTX bits to replicate the non-DTX bits, the DTX bits are supplied to a receiving end as redundant information of the non-DTX bits, such that the performance for demodulating the non-DTX bits by the receiving end is improved. In addition, when the binary symbols on one branch are all DTX bits, modulation mapping is performed on the binary symbols on the same branch and then a real value 0 is output. That is, when the input symbols on only one branch are all DTX bits, the transmission channel for this branch may be closed down alone, and thus the system transmission power is lowered.

    摘要: A User Equipment (UE), a method for determining a resource, a method for reporting a resource, and a system for distributing a resource are provided. The method for determining a resource includes: if transmission data on the carrier reaches maximum transmission data supported in a scope allowed by Service Grant (SG), and a transmission power of the UE is capable of improving a data transmission rate of the carrier, and the carrier and the other one carrier of the dual carriers are incapable of completing transmitting total buffer status data in the same delay period, determining that a resource distributed to a UE on one carrier of dual carriers of the UE is insufficient; otherwise, determining that the resource distributed for the UE on the carrier is sufficient. Therefore, a solution for reporting the resource of the dual carriers is provided, so as to improve a network performance.

    摘要: Method and apparatus for random access are provided. A base station sends access control information to a UE. The access control information includes an identifier of the UE and an access control command. The UE obtains an access time slot and a preamble signature according to the access control information received from the bases station. Then the UE initiate, according to the access time slot and the preamble signature, a random access procedure with a preamble power ramping. With the embodiments of the present invention, time delay in random access procedures may be decreased so as to enable the UE to complete the uplink access as quickly as possible and provide a feedback for a downlink transmission. Therefore efficiencies of the downlink transmission are enhanced.
