An apparatus and method for allocating resources in an Single Carrier-Frequency Division Multiple Access (SC-FDMA) communication system are provided, in which a Node B performs inter-subband hopping on a resource unit for a User Equipment (UE) on a frequency axis along which at least two subbands are defined, at each predetermined hopping time, determines whether to turn on or off mirroring in a subband having the hopped resource unit on a cell basis at the each hopping time, selects a resource unit by selectively mirroring the hopped unit according to the determination, and allocates the selected resource unit to the UE.

Methods of slot-level remapping physical uplink control channels into two resource blocks respectively located in different slots of a subframe, are adapted to a 3GPP LTE physical uplink in which ACK/NAK resource blocks may use an extended cyclic prefix, adapted to a complex 3GPP LTE physical uplink in which mixed resource blocks (those in which ACK/NAK and CQI channels coexist) may use the normal cyclic prefix, and adapted to a complex 3GPP LTE physical uplink in which mixed resource blocks may use an extended cyclic prefix.
摘要:
Methods and apparatus for remapping and regrouping transmission resources in a wireless communication system. First, a set of new permutation algorithms based on Galois field operation is proposed. Then the proposed algorithms and the known Pruned Bit Reversal Ordering (PBRO) algorithm are applied to several of various resource mapping schemes, including slot or symbol level Orthogonal Cover (OC)/Cyclic Shift (CS) mapping, cell-specific slot-level and symbol-level CS hopping patterns, and subframe and slot level base sequence hopping patterns.
摘要:
A method for the partitioning frequency resources used in the transmission of control signals and data signals by user equipments in a communication system. The control signals and data signals are for periodic transmission and dynamic transmission. Also provided is an apparatus and method for user equipments to determine the first frequency unit available for the transmission of dynamic control signals, such as acknowledgement signals associated respective reception of data signals configured through a scheduling assignment by a serving Node B. The utilization of the operating bandwidth is maximized by avoiding fragmentation and facilitates the achievement of reception reliability targets particularly for control signals.
