Problems solved by technology

In the original HSUPA and HSDPA system design, the two are designed independently, and each system has a set of control signaling and a channel for transmitting control signaling, so the signaling overhead is relatively large

Embodiment Construction

[0036] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] In the time division synchronous code division multiple access system HSPA+, according to the code channel allocation methods of HSUPA and HSDPA, the system will allocate two SFs for the HS-SCCH_less channel in HSDPA and the E-AGCH or E-AGCH_less channel in HSUPA =16 code channels. In order to effectively utilize the limited code channel resources, we propose a scheme for fusing information carried by HS-SCCH_less and E-AGCH or E-AGCH_less. It will be described in detail below in conjunction with the accompanying drawings.

[0038] figure 1 is a schematic structural diagram of the E-AGCH channel. Such as figure 1 As shown, in HSUPA scheduling, NodeB will se...

Abstract

The invention provides a fusion method of a downlink channel. The method is used for fusing an enhanced absolute grant channel or an enhanced absolute grant compressed channel and a high-speed shared control compressed channel in an enhanced high-speed packet access service of a TD-SCDMA system. The fusion method of the enhanced absolute grant channel and the high-speed shared control compressed channel comprises the following steps: determining the number of time slots available for service data in the enhanced high-speed packet access service; allocating the occupancy state of time slot information of the enhanced absolute grant channel and the high-speed shared control compressed channel according to the available time slots; and fusing information related to the enhanced absolute grant channel and the high-speed shared control compressed channel according to a combination mode predicted by uplink packet users and downlink packet users, thus forming a fusion channel of the enhancedabsolute grant channel and the high-speed shared control compressed channel. Therefore, the total resource configuration sum of the corresponding code channels is reduced, the expense is lowered, andthe system capacity is increased.

Description

technical field [0001] The present invention relates to time division synchronous code division multiple access system, more specifically, the present invention relates to a kind of downlink channel fusion method, is used in the HSPA+ of TD-SCDMA system, enhances absolute authorization channel (E-AGCH) and high speed The shared control compressed channel (HS-SCCH_less) is fused, and the enhanced absolute grant compressed channel (E-AGCH_less) and the high-speed shared control compressed channel (HS-SCCH_less) are fused. Background technique [0002] The further evolution and enhancement of HSPA (also known as HSPA+) is a new research project launched by 3GPP RAN in 2006, with the aim of achieving the same spectral efficiency as LTE within 5MHz. The main technical features of HSPA+ include: MIMO, Continuous Connectivity for Packet Data Users (CPC), and high-order modulation. [0003] Although the packet-oriented HSDPA / HSUPA (High Speed ​​Downlink Packet Access / High Speed ​​U...
