  • Patent number: 11376180
    Abstract: The present disclosure relates to a gate system for an overhead lifting rail system, comprising: a first gate comprising: a rail portion for supporting a lifting carriage; and a bridging element pivotally coupled adjacent a proximal end to the rail portion; and a second gate comprising: a rail portion for suspending a lifting carriage; and a bridging element support portion. Upon the first gate engaging with the second gate, a distal end of the bridging element of the first gate engages with the bridging element support portion of the second gate to form a bridge between the first gate and the second gate; and the distal end of the bridging element and the bridging element support portion are configured such that the ends of the bridging element are substantially aligned with the respective ends of the rail portions of the first and second gates.

  • Patent number: 11381344
    Abstract: According to certain embodiments, a wireless transmitter comprises a wireless interface and processing circuitry communicatively coupled to the wireless interface. The processing circuitry is operable to send, via the wireless interface, a transmission comprising a plurality of code blocks and a retransmission comprising at least some of the code blocks of the transmission. To send the retransmission, the processing circuitry rearranges the order of the code blocks such that the order of the code blocks in the retransmission differs from the order of the code blocks in the transmission.

  • Patent number: 11374703
    Abstract: A method for use in a transmitter includes sending a transmission comprising a transport block (TB) comprising a plurality of code blocks (CBs) arranged in one or more code block groups (CBGs). Each code block group includes one or more code blocks and each code block includes a plurality of coded bits. The transmission is sent to a receiver configured to use multi-bit hybrid automatic repeat request (HARQ) feedback per transport block. The method further includes receiving HARQ ACK or NACK feedback from the receiver one or more of the one or more code block groups of the transport block. The method further includes determining a number of code blocks or code block groups to send to the receiver in a retransmission based on at least the received HARQ ACK or NACK feedback.

  • Publication number: 20220183025
    Abstract: Systems and methods for priority-dependent Uplink Control Information (UCI) resource determination are provided. In some embodiments, a wireless device determines that one or more UCIs are to be multiplexed onto a Physical Uplink Shared Channel (PUSCH); determines priorities of the PUSCH and/or each of the one or more UCIs; determines at least one beta offset value for one or more UCIs based on one or more of the priorities; set or adjust a UCI code rate based on the at least one beta offset value; and transmit a UCI according to the UCI code rate. This provides a simple and consistent method to deduce beta offset value for UCI based on priorities of UCI and PUSCH. The solution supports possible multiple different beta offset values determined without extra explicit signaling, i.e., it helps to reduce DCI bits needed to indicate potentially multiple beta offset values.

  • Patent number: 11349502
    Abstract: A node receives transmissions associated with a given set of information bits, wherein each of the transmissions use a different polar code and share one or more information bits of the given set of information bits. The node determines, at each of a plurality of polar decoders of the node, soft information for each information bit included in an associated one of the transmissions, wherein each of the plurality of polar decoders is associated with a different transmission of the transmissions. The node provides, from each polar decoder of the plurality to one or more other polar decoders of the plurality, the determined soft information for any information bits shared by their respective associated transmissions, and uses the provided soft information in an iterative decoding process to decode one or more of the received transmissions.

  • Patent number: 11290210
    Abstract: According to some embodiments, a method for use in a wireless receiver comprises determining a transport block size, TBS, for a transport block to be communicated between the wireless transmitter and a wireless receiver via a physical channel transmission. The TBS determination uses a formula accounting for cyclic redundancy check, CRC, bits. The method further comprises transmitting the transport block according to the determined TBS. In particular embodiments the formula is based on an approximate transport block size, a number of code blocks, at least one of a number of CRC bits attached to the transport block, and a number of CRC bits added to each of the C code blocks.

  • Publication number: 20210345319
    Abstract: A set of resources, e.g. time and frequency resources, used for configured grants for a group of user equipments (UEs) is signalled to a second group of UEs. The second group of UEs consider the signalled set of resources to be reserved, and, therefore, avoid transmitting anything on the set of resources even if they are scheduled to do so.
