  • Patent number: 10178693
    Abstract: A method and apparatus for supporting a random access using a random access channel (RACH) are disclosed. The WTRU detects a format of control information in at least one control channel element (CCE) of a common area in a control portion of a downlink transmission. The control information indicates a resource allocation in a data portion of the downlink transmission. The WTRU recovers a random access response assigned to the WTRU from the indicated resource allocation of the data portion on a condition that the at least one CCE has a random access radio network terminal identifier (RA-RNTI) assigned to the WTRU.

  • Patent number: 10135610
    Abstract: A method and apparatus are disclosed relating to ciphering and de-ciphering of packet units in wireless devices during retransmission in wireless communications. The packet units are re-segmented with the ciphering done on the re-segmented packet unit or on a radio link control protocol data unit (RLC PDU) with or without segmentation. Alternatively, the re-segmentation is done on the radio link control service data unit (RLC SDU) with or without segmentation. Alternatively, the ciphering process and multiplexing of the RLC PDU is done in the medium access control (MAC) layer of a MAC PU before undergoing a hybrid automatic repeat request (HARQ) process for retransmission. Further, the ciphering process in the RLC is done on a packet data convergence protocol packet data unit (PDCP PDU).
