  • Patent number: 10340976
    Abstract: Methods and apparatus for providing quasi-licensed spectrum access within a prescribed area or venue, including to users or subscribers of one or more Mobile Network Operators (MNOs). In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum allocated by a Federal or commercial SAS (Spectrum Access System) to a managed content delivery network that includes one or more wireless access nodes (e.g., CBSDs) in data communication with a controller, and the core(s) of the MNO network(s). In one variant, the controller dynamically allocates (i) spectrum within the area or venue within CBRS bands, and (ii) MNO “roaming” users or subscribers to CBRS bands (e.g., via extant LTE-TD technology). In one particular implementation, the managed network comprises a Multiple Systems Operator (MSO) network such as a cable or satellite network, and the MSO and MNO coordinate to implement user-specific and/or data-specific policies for the roaming MNO subscribers.

  • Patent number: 10333760
    Abstract: Embodiments of the present disclosure relate to an OFDM-based data transmission method and an apparatus. In one example method, a transmitting device generates a data packet. The data packet comprises at least one orthogonal frequency division multiplexing (OFDM) symbol. The OFDM symbol comprises N sequentially numbered subcarriers. The N subcarriers are divided into L subblocks. Each subblock of the L subblocks comprises ?N/L? subcarriers including M pilot subcarriers. Start subcarriers of adjacent subblocks are adjacently numbered subcarriers. A numbering interval is the same for adjacent subcarriers in each subblock of the L subblocks. Each subblock of the L subblocks corresponds to one phase rotation signal. Signals carried on the subcarriers in each subblock of the L subblocks are signals obtained by multiplying original signals by a corresponding phase rotation signal. The transmitting device sends the data packet.

  • 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: 10298434
    Abstract: Compressed modulation feedback in codeword transmission with per-layer-modulation mapping is discussed. In the proposed compression schemes, the number of bits of feedback is compressed by excluding some of the allowed combinations of per-layer modulation orders. The excluded combinations are determined according to a fixed index delta, which prohibits any one modulation scheme being selected that has an index difference greater than the fixed index delta. The transmitting entity may then send per-layer modulation parameters, which may be the actual modulation orders identified or some relative parameter.
