  • Publication number: 20210021364
    Abstract: A system and method for permuting known and unknown message bits before encoding to provide a beneficial rearrangement of bits. Such a method can improve distance properties in the resulting subcode. In various embodiments, the structure of a beneficial rearrangement is dependent on the parameters of how known and unknown bits are grouped and on the specific type of code being used. Given these two parameters, the message bits can be rearranged to more efficiently leverage any apriori knowledge.

  • Publication number: 20200252251
    Abstract: A base station may generate and transmit a transport stream including a sequence of frames. A frame may include a plurality of partitions, where each partition includes a corresponding set of OFDM symbols. For each partition, the OFDM symbols in that partition may have a corresponding cyclic prefix size and a corresponding FFT size, allowing different partitions to be targeted for different collections of user devices, e.g., user devices having different expected values of maximum delay spread and/or different ranges of mobility. The base station may also dynamically re-configure the sample rate of each frame, allowing further resolution in control of subcarrier spacing. By allowing the cyclic prefixes of different OFDM symbols to have different lengths, it is feasible to construct a frame that confirms to a set payload duration and has arbitrary values of cyclic prefix size per partition and FFT size per partition. The partitions may be multiplexed in time and/or frequency.

  • Publication number: 20200244504
    Abstract: Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different encoding schemes. An apparatus may include one or more processing elements configured to receive, via a wireless radio, wireless data that includes a plurality of portions that each include multiple orthogonal frequency-division multiplexing (OFDM) symbols. Different ones of the portions have different frequency transform sizes and different sampling rates. The wireless data may also include control data that indicates the frequency transform sizes and sampling rates for the ones of the portions. The apparatus may select, based on the control data and a determined velocity of the apparatus, one or more but not all of the plurality of portions and may decode the selected one or more portions to determine data represented by the OFDM symbols in the selected one or more portions. Different portions of the wireless data may be adapted for decoding by devices moving at different maximum velocities.

  • Publication number: 20200099553
    Abstract: Methods and devices are described for polar encoding and decoding control information that has been modulated based on one or more identifiers of the transmitter and/or receiver. Some embodiments describe scrambling sequence design for multi-mode block discrimination on control information blind detection and decoding. Separate scrambling masks may be applied to disparate bit fields within a coded DCI message, wherein each of the scrambling masks is derived from a user equipment (UE)-specific identifier, a UE group identifier, or a base station identifier. Frozen bits of the polar code may be used to encode and transmit hybrid automatic repeat request (HARQ) acknowledgment messaging for early retransmission of unsuccessful downlink messages. A tiered process of UE identification may be employed to improve a balance between early termination of the decoding process and success of the UE identification process.
