Realizing method , system and device of high-speed uplink grouping access service

Abstract

The invention discloses a realizing method, a system and a device of high-speed uplink grouping access service. The main technical scheme comprises the steps that a base station determines scheduling resources according to a scheduling request sent by a terminal, sends the determined scheduling resource information to the terminal and initializes a maintained closed loop numerical value; and the terminal initializes the closed loop numerical value after receiving the scheduling resource information sent by the base station, determines sending power according to the initialized closed loop numerical value and sends data to the base station on the scheduling resources indicated by the scheduling resource information by adopting the determined sending power. According to the technical scheme, when the terminal determines the sending power adopted for sending the data, the maintained closed loop numerical value used for determining the sending power is consistent to the maintained closed loop numerical value in the base station, so the base station can accurately receive the data sent by the terminal, and reduces interference to other users, thus ensuring the system performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for realizing high-speed uplink packet access services. Background technique [0002] HSUPA (High Speed ​​Uplink Packet Access) technology is an uplink enhancement scheme proposed by 3GPP (3rd Generation Partnership Project). The channel structure of HSUPA service includes two uplink channels and two downlink channels, of which the two uplink channels are E-RUCCH (E-DCH Random access Uplink Control Channel, E-DCH uplink random access control channel) and E-PUCH (E-DCH PhysicalUplink Channel, E-DCH Physical uplink channel), the two downlink channels are E-AGCH (E-DCH Absolute Grant Channel, E-DCH absolute grant channel) and E-HICH (E-DCHHARQ Indicator Channel, E-DCH HARQ confirmation indication channel) . [0003] In the CELL-FACH (Forward Access Channel) state enhancement of the HSUPA service, if the UE has data to send, it will report...

Problems solved by technology

During the timing of the scheduling interval by the NodeB and the UE, if the UE does not correctly receive the scheduling resource information sent by the NodeB, the UE considers that the NodeB has not scheduled itself, and the timer for the UE to count the scheduling interval continues to count, while the NodeB ends at the E -After the scheduling resource information is sent to the UE on the AGCH, the timer for counting the scheduling interval is initialized, so that the timer on the UE side exceeds the GAP threshold earlier than the timer on the NodeB side, resulting in the P e-base Inconsistent, then, in the next scheduling, after UE receives the scheduling resource information sent by Node, according to the P e-base Determine the transmission power used to send uplink data, and use the transmission power to send data on the E-PUCH, and as mentioned above, due to the P e-base Inconsistency, therefore, the transmission power used by the UE to send data is inconsistent with the expected transmission power of the NodeB. If the transmission power used by the UE to send data is too large, the interference to other users of the system will be too large; if the transmission power used by the UE to send data If the power is too small, the NodeB cannot accurately receive the data sent by the UE, which will affect the demodulation and decoding of the data, and the performance of the system cannot be guaranteed.
