摘要： The present invention discloses a signal sending method, a signal receiving method, a terminal device, a base station, and a system, to ensure that a signal has a sufficiently large capacity when a PAPR is low, and reduce power consumption of the terminal device. The method in embodiments of the present invention includes: generating, by the terminal device, a first signal; performing, by the terminal device, code division processing on the first signal by using a target code division sequence selected from a code division sequence set, to generate a second signal, where any two code division sequences in the code division sequence set meet orthogonality and shift orthogonality; and sending, by the terminal device, the second signal to the base station at a corresponding time-frequency resource location.

摘要： Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID. According to the technical solution of the present invention, when the UE is connected to a serving gateway (SGW) through a serving general packet radio service support node (SGSN), the SGSN and the SGW set up a bearer between the UE and the PGW. Thus, resources of each network entity in a network are fully utilized.
