Abstract: Provided are a resource scheduling method, a resource determining method, an eNB, and a user equipment. The resource scheduling method for wireless communication is performed by the eNB. The wireless communication involves at least a first carrier and a second carrier. The resource scheduling method includes: transmitting a DCI in the first carrier to a UE to schedule downlink resources for a PDSCH of the second carrier, wherein the eNB is able to start transmitting a burst in the second carrier at a flexible time independent of the subframe boundaries of the second carrier after the second carrier is occupied by the eNB, and the DCI for a flexible PDSCH of the burst different from the normal PDSCH of the second carrier contains information on the time period scheduled for the flexible PDSCH. The flexible PDSCH and its corresponding RS can reuse the DwPTS subframe structure for minimal specification impact.

Abstract: A user equipment includes circuitry which selects a random access preamble sequence, and a transmitter which transmits the random access preamble sequence to a base station in a frequency bandwidth of an unlicensed band, and performs at least one of a first operation and a second operation. In the first operation, the circuitry selects a first sequence as the random access preamble sequence, the first sequence having a length longer than a length of a random preamble sequence used for a licensed band, and the transmitter transmits the first sequence in the frequency bandwidth of the unlicensed band. In the second operation, the circuitry selects a second sequence as the random access preamble sequence, the second sequence having a length equal to the length of a random preamble sequence used for the licensed band, and the transmitter transmits the second sequence with repetitions in the frequency bandwidth of the unlicensed band.

Abstract: The disclosure relates to a method for performing a random access procedure between a user equipment and a radio base station. The UE is configured with at least one unlicensed cell having an unlicensed cell frequency, via which the UE performs the random access procedure bandwidth. A minimum frequency bandwidth threshold is defined for transmissions via the unlicensed cell. The user equipment selects a random access preamble sequence for the random access procedure. A frequency bandwidth is determined by the UE for transmitting the random access preamble sequence via the unlicensed cell, the determined frequency bandwidth of the random access preamble sequence being at least the minimum frequency bandwidth threshold. The UE then transmits the random access preamble sequence to the radio base station such that at least the determined frequency bandwidth of the unlicensed cell is occupied.

Abstract: The present invention relates to reporting feedback concerning reception quality under at least two different assumptions of interference conditions, i.e. two interference hypotheses. In particular, a first and a second reception quality are determined for the same reference resource under two different interference hypotheses. The first and the second reception quality are then transmitted within the same channel state message.

Abstract: The wireless communication method used for transmitting interfering resource allocation information (IRAI) comprises a step of transmitting the IRAI through L1 signaling from the serving eNB to the victim UE, wherein the IRAI indicates only interfering resource block (RB) allocation within the bandwidth of RBs allocated to the victim UE at least in the case that the resource allocation type of the interfering UE is type 0, type 1, or type 2-L. The resource allocation type of the interfering UE can be signaled from the serving eNB to the victim UE within the downlink control information (DCI) of the victim UE for allocating resource. The indication mode of the IRAI for at least one interfering UE among the multiple interfering UEs that belong to a same interfering cell can be dependent on those interfering UEs whose IRAI has been indicated among the multiple interfering UEs.
