Definitions

  • HARQ can be classified into two types: synchronous and asynchronous.
  • the downlink traffic channel adopts an asynchronous adaptive HARQ scheme
  • the uplink traffic channel adopts a synchronous non-adaptive HARQ scheme.
  • the transmission of data (service) channels is based on a Grant-based transmission.
  • a communication unit configured to send the preamble sequence corresponding to the data packet and the data packet to the base station side.
  • the solution proposed in this embodiment includes the following processing flow:
  • the processing unit 71 is configured to determine a data packet to be sent, where the data packet to be sent may be specifically determined to be related to the current processing flow of the user equipment; for example, the current user equipment.
  • the user equipment can send a paging request, and then the data packet is the content to be included in the paging.
  • the user equipment may also send other types of data packets in other processing flows, which are all within the protection scope of the embodiment, but are not exhaustive here.
  • sequence 1 is shifted by K1 to obtain sequence 2.
  • K1 can be calculated according to a preset cyclic displacement relationship;
  • the correspondence between the index number of the preamble sequence and the data packet may be as follows:
  • the obtained K2 can be equal to 2*K1 or equal to 2+K1.
  • the embodiment may further determine, according to the feedback information sent by the base station, whether the retransmitted data packet is correctly detected on the base station side; specifically, the first processor 81 detects the base station. Sending feedback information from the side; extracting an index number of the preamble sequence from the feedback information, and determining, according to the index number, a receiving state of the data packet corresponding to the feedback information; wherein the receiving state characterizes the Whether the data packet is detected on the base station side is successful.
  • the Preamble sequence itself has a certain constraint relationship.
  • the Preamble sequence used for the number of transmissions of the data packet N is obtained by cyclically shifting the Preamble sequence used by the data packet with the number of transmissions M (TxM) by K times.
  • M, N, and K are integers, and N is an integer greater than M.
  • the detecting unit 92 is configured to compare the extracted preamble sequence with the preset preamble sequence set saved by itself to obtain a corresponding reference preset preamble sequence;
  • how to determine the number of transmissions corresponding to the received data packet based on the preamble sequence may include the following two resolution modes:
  • the number of transmissions can be combined with the preamble sequence, and the preamble sequence related to the number of transmissions is set in the data packet for interaction; thus, the information can be passed without the call information.
  • the sequence of sequences enables the receiver to know the number of times the data packet is transmitted, and can perform feedback based on this, thereby being more suitable for a transmission scenario with low latency and high reliability.
