  • Patent number: 10965389
    Abstract: A new method of performing interference estimation to allow the data packets to be efficiently delivered in an OFDM system. The interference estimation is performed on average over each frame for each mobile station individually in both frequency and time domains. Based on the estimated interference, the CIR can be determined by the BTS based on channel response estimates made by the BTS, or by the MS based on channel response estimates made for the uplink assuming a symmetrical channel. Numerical results show that the CIR estimation error could be very small if a sub-channel is considered as the minimum transmission unit. In terms of the aggregate throughput, the interference estimation method can provide a significant gain.

  • Patent number: 10917938
    Abstract: Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication are generally described herein. The UE may receive downlink control information (DCI) that schedules a transport block (TB) that includes multiple code blocks. The UE may determine a transport block size (TBS) based on the DCI. The UE may attempt to decode the code blocks. The UE may, if the TBS is greater than a predetermined threshold: bundle the code blocks into code block groups for hybrid automatic repeat request (HARQ) acknowledgement; and transmit a HARQ bit per code block group. The UE may, if the TBS is less than or equal to the threshold, transmit a HARQ bit that indicates whether a decode failure has occurred for at least one of the code blocks of the TB.

  • Patent number: 10904902
    Abstract: The present disclosure relates to a resource allocation procedure, performed between a user equipment and radio base station. The UE is configured with at least one numerology scheme, each associated with parameters partitioning time-frequency radio resources into resource scheduling units differently. The UE is configured with logical channels each of which is associated with at least one numerology scheme. A receiver of the UE receives from the radio base station an uplink scheduling assignment, which indicates uplink radio resources usable by the UE. A processor of the UE determines for which numerology scheme the received uplink scheduling assignment is intended based on the received uplink scheduling assignment. The processor performs a logical channel prioritization procedure by allocating the assigned uplink radio resources to the configured logical channels and by prioritizing those logical channels that are associated with the numerology scheme for which the uplink scheduling assignment is intended.

  • Patent number: 10904920
    Abstract: A wireless device initiates an Up-Link Trigger Based Multi-User communication by transmitting a trigger frame. The communication may be an Orthogonal Frequency Division Multiple Access communication. The trigger frame includes allocation information for resources of the communication, including Random Access (RA) allocation information. The trigger frame may also include a padding field after the allocation information. A length of the padding field is determined according to an amount of time needed for a station receiving the trigger frame to process the RA allocation information. The amount of time may correspond to a time between an end of a last RA allocation information and an end of a Physical layer Protocol Data Unit including the trigger frame. The amount of time may be determined according to a maximum processing time of stations associated with the wireless device, or may be determined according to a predetermined interval.
