Abstract
A wireless communication method is provided to include: sending, by a user device, a first message to a network device in a wireless network to initiate a 2-step random access to the wireless network; and receiving, in response to the first message, a second message to perform the 2-step random access, the second message including a field indicating whether a transport block size of a payload of the second message is scaled.
Claims11
A wireless communication method, including:
- sending, by a user device, a first message (msgA) to a network device in a wireless network to initiate a 2-step random access to the wireless network;
- and
- receiving, in response to the first message, a second message (msgB) to perform the 2-step random access, the second message including a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH) associated with a msgB radio network temporary identifier (msgB-RNTI), the PDSCH being scheduled by a downlink control information (DCI) scrambled by the msgB-RNTI,
- wherein the DCI scrambled by the msgB-RNTI has a total payload size equal to a legacy DCI format scrambled by a temporary cell radio network temporary identifier (TC-RNTI),
- wherein the DCI scrambled by the msgB-RNTI includes a field that is reinterpreted from at least one bit that is defined as an empty bit or a reserved bit in the legacy DCI format and indicates whether a transport block size of a payload of the second message is scaled and a scaling factor for the second message.
