  • Patent number: 10798747
    Abstract: Systems and methods for providing random access in a cellular communications network are disclosed. In general, the cellular communications network is an Orthogonal Frequency Division Modulation (OFDM) based cellular communications network (e.g., a 3GPP LTE cellular communications network) or similar multi-subcarrier based cellular communications network. Random access is performed using a Physical Random Access Channel (PRACH) including subcarriers having a subcarrier frequency spacing that is equal to a subcarrier frequency spacing in one or more other channels of the uplink (e.g., a Physical Uplink Shared Channel (PUSCH)). As a result, the subcarriers in the PRACH are orthogonal to the subcarriers in the other channel(s) of the uplink, which in turn reduces, or substantially eliminates, interference between the PRACH subcarriers and the subcarriers of the other channel(s) of the uplink.

  • Patent number: 10707996
    Abstract: A framework for error correction coding that takes into account the difference in bit significance in the source symbols by using an appropriate error metric and minimizing it using a Bayes decoder and an optimized codebook. The Bayes decoder performs better than standard soft and hard minimum distance decoding and the optimized codebook performs better than classical linear block codes, e.g., Hamming codes. The error metric is a norm in information symbol space and is based on a loss function appropriately defined according to an approach for assigning significance to the various bits in the source bit stream. The Bayes decoder of this metric is defined and an optimized codebook generated that optimizes this metric under a noisy channel. The framework for error correction coding is implemented for increased reduncancy in a communications system or a data storage system and is optimized to combat noise in such systems.

An existing field “Doppler mode” in a preamble is redefined into a dual-use field for indicating channel variation for a short packet as well as for indicating presence of mid-amble(s) in a long packet. Particularly, for a long packet (longer than a predefined data transmission time or a longer than a predefined number of data symbols), the two possible values of the one-bit “Doppler mode” field indicate whether there is any mid-amble carrying training symbols in the payload. On the other hand, for a short packet, the two possible values in the same field indicate whether the channel for transmitting the instant packet is currently time-variant as determined by the transmitting device.

  • Patent number: 10244562
    Abstract: Systems and methods for providing random access in a cellular communications network are disclosed. In general, the cellular communications network is an Orthogonal Frequency Division Modulation (OFDM) based cellular communications network (e.g., a 3 GPP LTE cellular communications network) or similar multi-subcarrier based cellular communications network. Random access is performed using a Physical Random Access Channel (PRACH) including subcarriers having a subcarrier frequency spacing that is equal to a subcarrier frequency spacing in one or more other channels of the uplink (e.g., a Physical Uplink Shared Channel (PUSCH)). As a result, the subcarriers in the PRACH are orthogonal to the subcarriers in the other channel(s) of the uplink, which in turn reduces, or substantially eliminates, interference between the PRACH subcarriers and the subcarriers of the other channel(s) of the uplink.
