  • System and method for small traffic transmissions
    Patent number: 10945243
    Abstract: A grant-free transmission mode may be used to communicate small traffic transmissions to reduce overhead and latency. The grant-free transmission mode may be used in downlink and uplink data channels of a wireless network. In the downlink channel, a base station transmits packets to a group of UEs in a search space without communicating any transmission code assignments to the UEs. The UEs receive the downlink packets using blind detection. In the uplink channel, UEs transmit packets in an access space using assigned access codes which are either independently derived by the UEs or otherwise communicated by the base station using a slow-signaling channel. Hence, the grant-free transmission mode allows mobile devices to make small traffic transmissions without waiting for uplink grant requests.

  • System and method for pilot signal transmission
    Patent number: 10911281
    Abstract: Longer pilot sequences can be supported by transmitting pilot values of a given pilot sequence over different orthogonal frequency division multiplexed (OFDM) symbols of an uplink frame. The pilot values may be contiguous, or non-contiguous, with one another in the time domain. Consecutive pilot values in a pilot sequence may be transmitted in different OFDM symbols of the frame. For example, odd pilot values (e.g., P1, P3, P5 . . . ) in a pilot sequence may be transmitted over a different OFDM symbol than even pilot values (e.g., P2, P4, P6 . . . ) in the pilot sequence. Alternatively, a leading subset of pilot values in a pilot sequence is transmitted over a different OFDM symbol than a trailing subset of pilot values in the pilot sequence.

  • Systems and methods for sparse code multiple access
    Patent number: 10771305
    Abstract: Coding gains can be achieved by encoding binary data directly to multi-dimensional codewords, which circumvents QAM symbol mapping employed by conventional CDMA encoding techniques. Further, multiple access can be achieved by assigning different codebooks to different multiplexed layers. Moreover, sparse codewords can be used to reduce baseband processing complexity on the receiver-side of the network, as sparse codewords can be detected within multiplexed codewords in accordance with message passing algorithms (MPAs).
