Abstract: Embodiments of this application provide a method for processing information bits in a wireless communication network. A communication device receives a radio resource control (RRC) signaling, wherein the RRC signaling comprises time window information and time unit format information, wherein the time window information comprises a hybrid automatic repeat request (HARQ) time sequence K1 set, wherein K1 is a time relationship between a time unit of a physical downlink shared channel (PDSCH) and a time unit of a physical uplink control channel (PUCCH), or wherein the K1 is a time relationship between a time unit of a (PDSCH) and a time unit of a physical uplink shared channel (PUSCH). The device determines HARQ feedback information based on the time window information and the time unit format information and sends the HARQ feedback information.

Abstract: A method and an apparatus for obtaining a mapping between a random access parameter and a resource are disclosed in embodiments of the present invention, where the method includes: obtaining a random access parameter list, and obtaining a serial number of a parameter in the random access parameter list; obtaining a resource list; and obtaining a mapping between the random access parameter and a common enhanced dedicated channel resource in the resource list according to the obtained serial number of the random access parameter and the total number of resources in the obtained resource list, so that a network side device determines, according to the random access parameter sent by a UE, whether a corresponding common enhanced dedicated channel resource is available. In this way, a mapping between a signature and a default common E-DCH resource can be defined, and a problem of relatively low random access efficiency is solved.
