Abstract: The present disclosure proposes a user resource reservation method and apparatus, an access point, and a network server. The user resource reservation method includes: predicting a next access point that is to be reached by a user; and sending resource reservation designating information to the access point, so that the access point reserves a resource for the user according to the resource reservation designating information. In embodiments of the present disclosure, a next access point that is to be reached by a user is predicted and the access point is instructed to reserve a resource for the user, that is, a next access point is instructed in advance to reserve an appropriate resource for the user, so that the user is successfully handed over to a network, and a probability of successful handover of the user to the network increases, thereby improving user experience.

Abstract: A Polar code rate matching method and a rate matching apparatus are disclosed. The method includes: dividing a system Polar code output by a Polar code encoder into system bits and parity bits; interleaving the system bits to obtain a first group of interleaved bits, and interleaving the parity bits to obtain a second group of interleaved bits; and determining a rate-matched output sequence based on the first group of interleaved bits and the second group of interleaved bits. System bits and parity bits are separately interleaved, to obtain a rate-matched output sequence, so that a sequence structure after interleaving is more random, which can reduce an FER, thereby improving HARQ performance, and ensuring reliability of data transmission.

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.
