  • Patent number: 10680767
    Abstract: A method for mapping a physical hybrid automatic repeat request indicator channel (PHICH) is described. The method for mapping a PHICH includes determining an index of a resource element group transmitting a repetitive pattern of the PHICH, according to a ratio of the number of available resource element groups in a symbol in which the PHICH is transmitted and the number of available resource element groups in a first or second OFDM symbol, and mapping the PHICH to the symbol according to the determined index. In transmitting the PHICH, since efficient mapping is performed considering available resource elements varying with OFDM symbols, repetition of the PHICH does not generate interference between neighbor cell IDs and performance is improved.

    Abstract: Disclosed are a wireless communication base station device and a division number determination method that improve the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit.

  • Patent number: 10644840
    Abstract: An efficient Hybrid Automatic Repeat Request (HARQ) operation for low-latency and high-performance services in one radio access technology (RAT) in a wireless communication network is proposed. Under the proposed single HARQ operation scheme, an adaptive HARQ-ACK feedback timing is applied based on UE conditions and UE capability to support the tradeoff between low-latency and high-performance applications. In one embodiment, UE signals the network its HARQ-ACK timing capability. Furthermore, an adaptive number of HARQ processes is applied with a fixed HARQ soft buffer size because the hardware cost for HARQ soft buffer does not linearly increase with the number of HARQ processes. In one embodiment, UE determines a nominal HARQ soft buffer size and HARQ soft buffer size for each HARQ process based on a network-configured HARQ process number.

The base station may also dynamically re-configure the sample rate of each frame, allowing further resolution in control of subcarrier spacing. By allowing the cyclic prefixes of different OFDM symbols to have different lengths, it is feasible to construct a frame that confirms to a set payload duration and has arbitrary values of cyclic prefix size per partition and FFT size per partition. The partitions may be multiplexed in time and/or frequency.

A CSI-RS for each antenna port is allocated to REs or subcarriers on a basis of a symbol or symbol axis in a subframe or Resource Block (RB), and is allocated in such a manner that a distance between neighboring CSI-RS allocation REs or subcarriers may be 3 REs or subcarriers. Accordingly, in the range of following CSI-RS transmission overhead, CSI-RSs are allocated to a time-frequency resource domain in such a manner so as to have perfect orthogonality or quasi-orthogonality according to cells or cell groups. Then, the CSI-RSs, which have been allocated to the time-frequency resource domain, are transmitted.

  • Patent number: 10531325
    Abstract: A method performed by a first network node (110) for determining whether a performance of a cell (130) associated with a second network node (120) is degraded or not. The first network node (110) and the second network node (120) operate in a wireless communications network (100). The first network node (110) obtains (201) a first set of values making up a pattern comprising a set of values indicative of a performance of the cell (130). The first network node (110) then determines (204) a first correlation between the obtained first set of values and a generated set of values. The generated set of values is indicative of a degraded performance of the cell (130). The first network node (110) then determines (206) whether the performance of the cell (130) is degraded or not based on the determined first correlation, with respect to a first threshold.
