Embodiment Construction

[0020] The WCDMA protocol stipulates that in the HSMAC scheduling process, the following seven conditions must be met:

[0021] 1. Each HS_DSCH public shared physical channel can only carry at most one data block in a 2MS subframe;

[0022] 2. Each HS_SCCH physical channel can only be scheduled once in a subframe;

[0023] 3. Each UE can only be scheduled once in its scheduling period;

[0024] 4. Each HARQ of UE can only be scheduled once in its ACK_NACK response cycle;

[0025] 5. Each HARQ of the UE is separated from its previous scheduling by at least one frame period;

[0026] 6. The total channel energy of HS_SCCH and HS_DSCH in each subframe cannot exceed the total energy allocated to HSDPA by the cell.

[0027] 7. If the data block scheduled by HARQ does not receive an ACK response within 3 frame periods, it will be discarded.

[0028] The implementation of the present invention is divided into four parts:

[0029] The present invention realizes HSMAC scheduling b...

Abstract

This invention discloses one HSMAC adjusting method based on dispatched pattern, which comprises the following steps: entering 2MS dispatching and if firstly entering one new frame dispatching circle to initiating current frame public materials codes, HS-SCCH signal materials codes and dispatching pattern data, current frame dispatching HARQ and its belonged dispatch frame position mask; if front frame materials code is not zero, selecting one HARQ dispatching process to get position coordinate and to repair HARQ and its sub frame position mask, HS-SCCH signal material codes, public signal materials codes to enter next dispatching signal materials to wear out remaining data block of zero.

Description

technical field [0001] The invention relates to the technical field of high-speed downlink packet access, in particular to an HSMAC fast scheduling method based on scheduling patterns. Background technique [0002] In order to satisfy services such as downloading or streaming media, W-CDMA requires the system to provide a higher transmission rate and less delay. The air interface has been improved from these two aspects, and HSDPA (high-speed downlink packet access) technology has been introduced to support a peak rate of up to 13.9Mbit / s. [0003] The HSDPA MAC processing module (HSMAC) mainly completes the MAC-HS (responsible for processing HARQ operation and fast scheduling algorithm) function of NodeB (base station). The HSMAC scheduling algorithm controls the allocation of shared resources and determines the performance of the entire system to a large extent. [0004] The MAC frame length of HSDPA is 10MS, and the subframe length is 2MS. During the establishment of t...
