  • Inter-carrier interference compensation
    Patent number: 11477058
    Abstract: An inter-carrier interference method comprises: receiving one or more OFDM signal comprising plural blocks of OFDM subcarriers of a first type and plural blocks of OFDM subcarriers of a second type, wherein the frequencies of the subcarriers of each block of OFDM subcarriers of the first type are contiguous and wherein the plural blocks of subcarriers of the first type are distributed amongst the plural blocks of subcarriers of the second type; for each of the plural blocks of subcarriers of the first type, estimating inter-carrier interference components; estimating inter-carrier interference components for the subcarriers of the second type using the inter-carrier interference components estimated for the plural blocks of subcarriers of the first type; and compensating for inter-carrier interference in the plural blocks of subcarriers of the second type using the inter-carrier interference components estimated for the sub-carriers of the second type, thereby to generate plural compensated blocks of subcarri
    Type: Grant

  • Maximum power reduction for uplink bandwidth part for wireless networks
    Patent number: 11419058
    Abstract: A technique includes controlling uplink transmission power of auser device, wherein a resource block allocation for the user device includes resource blocks in a user device channel bandwidth that is a part of a base station channel bandwidth and the user device channel bandwidth is less than the base station channel bandwidth, wherein the controlling uplink transmission power of the user device comprises reducing a maximum transmission power of the user device for an uplink transmission via the resource block allocation by a maximum power reduction value that is determined based on a distance of the resource block allocation from at least one edge of the base station channel bandwidth.
