Embodiment Construction

[0035] In order to clearly describe the present invention, the following uses the High Speed ​​Packet Access (HSPA for short) service of TD-SCDMA as an example to illustrate the current same-frequency networking mode of TD-SCDMA.

[0036] With the evolution of the TD-SCDMA system from the R4 version to the R7 version, the services of the TD-SCDMA system have increased on the basis of the circuit switching (Circuit Switch, referred to as CS) service and data switching (Packet Switch, referred to as PS) service. High Speed ​​Downlink Packet Access (HSDPA for short) service based on R5 version, High Speed ​​Uplink Packet Access (HSUPA for short) service based on R6 version, and HSPA service based on R7 version, Among them, HSPA is a service combining HSDPA service and HSUPA service.

[0037]In the HSPA service, 9 new physical channels are introduced: Physical Shared Channel (HSDPA-Physical Downlink Shared Channel, referred to as HS-PDSCH), the downlink physical shared channel of ...

Abstract

The invention discloses a co-channel networking method and a base station. The method comprises the step of preferentially allocating downlink control channels of any two adjacent cells in all the cells, which utilize the same frequency point bearer service, in different time slots. By applying the invention, the downlink control channels of two adjacent cells which utilize the same frequency point bearer service are allocated in different time slots, thus downlink co-channel interference among adjacent cells can be effectively controlled and the communication capability of a terminal can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a same-frequency networking method and a base station of a mobile communication system. Background technique [0002] In the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA for short) system, the communication is mainly carried out in the same-frequency networking with N frequency points. Using this networking method, compared with For the Wide Code Division Multiple Access (WCDMA for short) system and CDMA2000 (Code Division Multiple Access 2000) in the third-generation mobile communication, the TD-SCDMA system can obtain higher spectrum utilization. [0003] Based on the N-frequency point TD-SCDMA network cell, the main frequency carrying the common channel adopts the method of inter-frequency cellular networking, which can effectively reduce the same-frequency interference of the common channel between neighboring cells. In the specific implementation process, when...
