  • Patent number: 10312983
    Abstract: A transmitting radio node (10) precodes a transmission from a one-dimensional antenna array (12) to a receiving radio node (50). The array (12) includes co-polarized antenna elements (14) aligned in the array's only spatial dimension. The transmitting radio node (10) precodes the transmission from each of different subarrays (34a, 34b) of the antenna elements (14) using a coarse-granularity precoder that is factorizable from a multi-granular precoder targeting the given spatial dimension of the array (12) at different granularities, so as to virtualize the subarrays (34a, 34b) as different auxiliary elements (38a, 38b). The transmitting radio node (10) also precode the transmission from the different auxiliary elements (38a, 38b) using one or more finer-granularity precoders that are also factorizable from the multi-granular precoder. In this case, the coarse granularity precoders and the one or more finer-granularity precoders are represented within one or more codebooks (26) used for said precoding.

  • Patent number: 10187895
    Abstract: A method and system to help control air interface resource allocation. A base station monitors for each served UE a ratio of physical resource block (PRB) allocation to queued data, as a PRB/data ratio. The base station then detects that the PRB/data ratio of a first served UE has been threshold lower than the PRB/data ratio of each of a plurality of second served UEs, and the base station responsively selects at least one of the second UEs based on its modulation and coding scheme (MCS) being relatively high, and the base station limits PRB allocation to the selected UE to help reduce its PRB/data ratio and to thereby help achieve a level of fairness in PRB allocation.

  • Patent number: 10148460
    Abstract: Methods, systems, and apparatuses are described for providing device(s) with additional processing time to process a packet received wirelessly while still meeting the legacy SIFS time constraint. The additional processing time may be achieved by adding, by a device transmitting the packet, padding and/or a packet extension to the last symbol of the packet. The additional processing time provided to the device(s) advantageously reduces the amount of extra hardware that would normally be added to meet the SIFS time constraint. The amount of padding and/or packet extension to be added to the last symbol is balanced to minimize the complexity of the device(s) against the reduction in system efficiency incurred by the device(s).
