Embodiment Construction

[0043]Aiming at the problems existing in the existing HSPA system with the fixed configuration mechanism of channel multiplexing, the embodiment of the present invention dynamically adjusts the allocation mode of accompanying channels according to the current number of HSPA users, so as to meet the needs of access users while ensuring access as much as possible. The physical performance of the accompanying channel of the incoming user.

[0044] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] see Figure 3a , is a schematic flow chart of the HSPA system accompanying channel allocation method in the embodiment of the present invention, the method includes the following steps:

[0046] Step 301, determine the current number of HSPA users;

[0047] Step 302, according to the determined number of HSPA users, judge whether to adopt the multiplexing mechanism of the accompanying channel, that is, whether...

Abstract

The invention discloses a distribution method of adjoint channels of an HSPA (High Speed Packet Access) system, a base station and a system. The method comprises the following steps of: determining the quantity of HSPA users of a current dispatching cycle; determining an adopted adjoint channel resource distribution mode according to the determined quantity of the HSPA users, wherein the adjoint channel resource distribution mode comprises a multiplexing mode or a non-multiplexing mode; and distributing adjoint channel resources to the HSPA users according to the determined adjoint channel resource distribution mode. By adopting the invention, aiming at the problem of a fixed configuration mechanism for complexing the adjoint channels of the traditional HSPA system, the adjoint channel distribution mode is dynamically adjusted according to the current quantity of the HSPA users so as to guarantee the physical properties of the adjoint channels of accessed users as far as possible while meeting the requirements of the accessed users.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for allocating accompanying channels in an HSPA system, a base station and a system. Background technique [0002] HSPA (High Speed ​​Packet Access, High Speed ​​Packet Access) is the collective name of two technologies, HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) and HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access). AMC (adaptive modulation and coding), HARQ (hybrid automatic retransmission), high-order modulation (16QAM) and other technologies, and fast scheduling on the base station side, so that it can quickly and adaptively reflect changes in user channels and obtain higher user Peak rate and cell data throughput. [0003] Currently, the TD-SCDMA HSDPA system involves five channels, namely: [0004] HS-PDSCH: High-Speed ​​Physical Downlink Shared Channel, high-speed physical downlink shared chan...
