    摘要: The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4 th -Generation (4G) communication system such as Long Term Evolution (LTE). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 10 GHz ∼ 100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The initial deployment of mmWave/cmWave system is expected to operate as non-standalone system to provide additional radio resources to the UE which would be connected to the LTE-A cell for coverage purpose. The present disclosure covers initial access aspects of a UE on such future wireless system.

    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 and apparatus for efficient open loop power control in a packet data mobile communication system using Frequency Division Multiple Access (FDMA) is disclosed. When a target Signal-to-Interference Ratio (SIR) required for the determination of transmission power using open loop power control is set, influence upon neighboring cells is considered. In other words, when a Mobile Station (MS) is located at a cell boundary and thus induces large interference with its neighboring cells, the target SIR is set low. In the other case, the target SIR is set high. Therefore, by adjusting transmission power according to the position of an MS and a relationship between the MS and the neighboring cells, support for high data rate can be provided to an MS that is located near a Base Station (BS) and interference induced by an MS that is located around a cell boundary can be minimized. In this way, the entire system capacity can also be improved.
