USER EQUIPMENT COLLISION DETECTION METHOD, USER EQUIPMENT, AND BASE STATION

摘要

The present invention provides a user equipment collision detection method and apparatus. The user equipment collision detection method includes: sending, by user equipment, a collision detection request on a common E-DCH to a base station, where the collision detection request carries a first radio network temporary identifier (RNTI) corresponding to the user equipment, so that the base station determines whether the common E-DCH is occupied by other user equipment than the user equipment; receiving, by the user equipment, an acknowledgement message sent by the base station, where the acknowledgement message carries absolute grant (AG) information and a cyclic redundancy check (CRC) code; and determining, by the user equipment according to the first RNTI, and the AG information and the CRC code that are carried in the acknowledgement message, whether the common E-DCH is an available resource.

1. A user equipment collision detection method, comprising:
sending, by user equipment, a collision detection request on a common enhanced uplink dedicated channel (E-DCH) to a base station, wherein the collision detection request carries a first radio network temporary identifier (RNTI) corresponding to the user equipment, so that the base station determines whether the common E-DCH is occupied by other user equipment than the user equipment; receiving, by the user equipment, an acknowledgement message sent by the base station, wherein the acknowledgement message carries absolute grant (AG) information and a cyclic redundancy check (CRC) code; and determining, by the user equipment according to the first RNTI, the AG information, and the CRC code, whether the common E-DCH is an available resource.
