Method and apparatus for re-synchronizing of temporary UE IDs in a wireless communication system

摘要

Methods and apparatuses for re-synchronizing Cell Radio Network Temporary Identifiers (C-RNTIs) in a wireless communication system are disclosed. In an aspect, a random access preamble is sent for random access by a user equipment (UE) and a random access response (RAR) is received that includes a temporary C-RNTI. If the UE already has a valid C-RNTI, a message is sent that includes the valid C-RNTI instead of the temporary C-RNTI as a C-RNTI for the UE. In another aspect, a random access preamble for random access is received and a RAR is sent that includes a temporary C-RNTI. A message is received that includes a valid C-RNTI instead of the temporary C-RNTI as a C-RNTI for a UE if the UE already has the valid C-RNTI.

主权项

1. A method for wireless communication, comprising:
sending a random access preamble for random access by a user equipment (UE); receiving a random access response (RAR) that includes a temporary Cell Radio Network Temporary Identifier (C-RNTI); using the temporary C-RNTI as a C-RNTI for the UE when a valid C-RNTI is not already available, wherein the valid C-RNTI is a C-RNTI for the UE from prior to performing the random access; discarding the temporary C-RNTI and using the valid C-RNTI when available; and sending a transmission after receiving the RAR, the transmission comprising the valid C-RNTI when available or the transmission not comprising C-RNTI information when the valid C-RNTI is not available.
