Methods and apparatuses for communication between a mobile terminal and a base station during a random access procedure

摘要

The disclosure relates to a method in a mobile terminal for communication with a base station in a wireless network during a random access procedure. The method comprises exchanging (202) between the mobile station and the base station, during the random access procedure, information on a selected DRX scheme to be used for communication between the mobile terminal and the base station in the random access procedure, setting (204) the mobile terminal in DRX mode according to the selected DRX scheme and receiving (206) at least one message from the base station during the random access procedure, wherein the at least one message was transmitted according to the selected DRX scheme. The disclosure also relates to a corresponding method in a base station, and to a mobile terminal and a base station. By such methods, base station and mobile terminals, battery power in a mobile terminal may be saved during a random access procedure.

1. A method in a mobile terminal for communication with a base station in a wireless network during a random access procedure, the method comprising:
exchanging, during the random access procedure between the mobile terminal and the base station, information on a selected discontinuous reception (DRX), scheme to be used for communication between the mobile terminal and the base station in the random access procedure, wherein exchanging information on the selected DRX comprises sending a random access preamble, out of a plurality of preambles, that is mapped to the selected DRX scheme; setting the mobile terminal in DRX mode according to the selected DRX scheme;and receiving at least one message from the base station during the random access procedure, wherein the at least one message was transmitted according to the selected DRX scheme.
