Abstract: Embodiments of the present invention disclose a data boundary determining method, an indication information sending method, and apparatuses thereof. The boundary determining method includes: acquiring, by a base station in which a non-reference cell locates, timing information of a reference cell, or a parameter used to determine boundary information of a high speed dedicated physical control channel (HS-DPCCH); and determining, by the base station, the boundary information of the HS-DPCCH according to the timing information of the reference cell or the parameter, where the boundary information is used by the base station to search for the HS-DPCCH. The present invention solves a technical problem in the prior art that a base station in which a non-reference cell locates is not capable of finding a correct boundary of the HS-DPCCH and therefore causes a decrease in downlink data transmission performance.

Abstract: Embodiments of the present invention disclose a method, a device, and a system for sending, receiving, and determining timing reference information, and pertain to the communications field. The method for sending timing reference information includes: acquiring access time difference information reported by a mobile terminal; generating timing reference information according to the access time difference information, where the timing reference information includes identifier information of a timing reference cell; and sending the timing reference information to the mobile terminal. By technical means of determining one of two cells with different downlink channel timings as a timing reference cell and using the timing reference cell as a benchmark to feed back HARQ-ACK information, the present invention solves a timing problem encountered when a UE uses a same HS-DPCCH to jointly feed back two pieces of HARQ-ACK information of a serving cell and an assisting serving cell.

Abstract: A configuration method for transmitting TPC command, a TPC command transmission method, and an apparatus. In the present invention, a radio network controller sends indication information to a terminal and a serving base station of the terminal to indicate a sending timeslot of an uplink TPC command of the terminal, so that sending timeslots of different TPC commands can be indicated for different terminals, and uplink TPC commands of multiple terminals are staggered in a timeslot. In this way, even if F-DPCHs of multiple terminals are configured with a same timeslot format, it can be avoided that locations of the uplink TPC commands are the same, and further a TPC peak-to-average ratio is lower than that in the prior art.
