Embodiment Construction

[0027] The method and device provided by the present invention for reducing interference between HSUPA users provided by the present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0028] Aiming at the problems in the scheduling process, the embodiment of the present invention proposes a scheme of forcing scheduling when the user cannot get scheduling for a period of time, such as Figure 4 As shown, the method for reducing interference between HSUPA users provided by the embodiment of the present invention includes:

[0029] Step S401, when the scheduling cycle is reached, determine whether there is a first type of user who requests scheduling but has not been scheduled after the set first time, if so, execute step S402;

[0030] Specifically, the timer is generally initialized when a RUCCH request for scheduling is received, and it is judged whether the timer of each user expires when the scheduling period is ...

Abstract

The invention discloses a method for reducing high speed uplink packet access (HSUPA) user interference and a device. The method comprises the steps that: when a scheduling period is reached, whether a first category of users which are requested for the scheduling but are free from being scheduled at the time exceeding exist or not is determined; if the first category of users exist, all users requesting for the scheduling are arranged in priority, and the scheduling priority of the first category of users is higher than that of a second category of users except for the first category of users in the users requesting for the scheduling; and after the arrangement is completed, the users in the row are scheduled according to the sequence from higher priority to the lower priority, and the interference power reference value Pebase of the scheduled users is updated after the scheduling. Due to the adoption of the method, the interference of the switching of the users on the present users in the subdistrict can be effectively eliminated, and the CU probability of the present users of the subdistrict can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for reducing HSUPA user interference. Background technique [0002] HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) users send SI (Scheduling Information, scheduling information) to NB (Node B, base station). After NB correctly receives the SI information of HSUPA users, the NB scheduler In UPH (UE Power Headroom, the maximum transmit power available to UE and the reference value of interference power Pebase (reflecting E-PUCH (E-DCH (Enhanced dedicated channel, enhanced dedicated channel) Physical Uplink Channel, E-DCH physical uplink channel)) slot interference power), SNPL (Serving and Neighbor Cell Pathloss, serving cell and adjacent cell path loss information) and other information, combined with Pebase and carrier maximum received power RoT to perform priority queuing according to the proportional fair PF sched...
