Description

Processing method and system for determining mapping of relative grant and absolute grant by node B
Technical Field
The present invention relates to a relative grant and absolute grant processing technology, and more particularly, to a method and system for determining a relative grant and an absolute grant mapping by a node B in a high speed uplink packet access system.
Background
High Speed Uplink Packet Access (HSUPA) is a technology for Uplink performance enhancement. The HSUPA increases the data transmission rate in the uplink direction from the terminal to the access network when the channel condition is good by effectively using the power. The HSUPA technology follows most of the characteristics of the conventional wireless communication technology, such as cell selection, synchronization, random access, basic mobility management, etc. The key technology of HSUPA is as follows: hybrid Automatic repeat request (HARQ), fast scheduling by the node B, short Transmission Time Interval (TTI) of 2 ms.
The fast scheduling technique of the node B moves the scheduling in the conventional wireless communication system, which is in charge of the radio network controller, to the node B. In each transmission time interval, the terminal reports the information such as the data volume to be sent in the current terminal cache and the current available power of the terminal to the node B through the uploading scheduling information. The node B determines the maximum uplink resource that can be currently used by the terminal (determines the highest transmission rate currently available to the terminal) according to a node B fast Scheduling algorithm, that is, according to the load of the cell, the uplink interference condition of the cell, the amount of data to be sent by the terminal, the upper limit of the terminal capability, the Scheduling policy of the node B, the current channel quality of the terminal, and the like, and informs the terminal by issuing a Scheduling Grant (Scheduling Grant). By the technology, the round-trip delay of the scheduling signaling can be greatly reduced, the quick scheduling response can be made, and the wireless link resource can be better utilized, so that the system throughput is improved.
The scheduling grant is a control signaling sent by the node B to the terminal in the downlink direction to indicate the maximum uplink resource that can be used by the terminal (which determines the highest transmission rate currently available to the terminal). The scheduling grant has
The following characteristics:
the scheduling grant is only used for Enhanced Transport format combination (E-TFC) selection algorithms.
The scheduling grant controls the maximum enhanced dedicated channel dedicated physical data channel (E-DPDCH)/Dedicated Physical Control Channel (DPCCH) power ratio for transmitting data in the active HARQ process. Wherein, the Enhanced Dedicated Channel is denoted as Enhanced differentiated Channel, abbreviated as E-DCH; the special Physical Data Channel is represented as a Dedicated Physical Data Channel; the DPCCH is an abbreviation of a Dedicated Physical Control Channel.
There are 2 types of authorization: absolute grants and relative grants. The absolute grant provides the uplink maximum power resource available for the terminal, and the maximum allowed E-DPDCH/DPCCH power ratio is used for each HARQ process. The relative grant means that the terminal adjusts UP or decreases by a relative value on the basis of the power resource used by the previous scheduling, the serving relative grant specifically includes 3 values of UP (UP), HOLD (HOLD), and Decrease (DOWN), and the non-serving relative grant specifically includes 2 values of HOLD and DOWN.
The node B refers to the following table 1 or table 2 to send an absolute grant, where table 1 is a first absolute grant value mapping table, and table 2 is a second absolute grant value mapping table.

TABLE 4
The node B sends the relative grant of the service, which specifically includes 3 values of UP, HOLD, and DOWN. The node B sends the relative grant of the service according to the table 3 or the table 4, calculates a reference power ratio, calculates an expected scheduling grant value according to a node B fast scheduling algorithm, compares the expected scheduling grant value with the reference power ratio, looks at whether the scheduling grant value is adjusted up or maintained or reduced on the basis of the reference power ratio, and then sends out a corresponding relative grant control signaling of the service. Wherein: the reference power ratio is: and the E-DPDCH/DPCCH power ratio used for E-TFC selection for the previous transmission time interval with the same HARQ process for this data transmission.
The node B sends the non-serving relative grant, which specifically includes 2 values of HOLD and DOWN. The node B sends out non-service relative authorization according to the table 3 or the table 4, calculates a reference record storage power ratio, calculates an expected scheduling authorization value according to a node B fast scheduling algorithm, compares the expected scheduling authorization value with the reference record storage power ratio, and sends out corresponding non-service relative authorization control signaling after seeing that the expected scheduling authorization value is kept unchanged or reduced on the basis of the reference record storage power ratio. Wherein: the reference record saving power ratio is: the new value recorded and saved when the power ratio of the E-DPDCH to the DPCCH used for the E-TFC selection in the previous transmission time interval with the same HARQ process of the data transmission is updated to the new value.
There are two modulation modes used by HSUPA, one is Quadrature Phase Shift Keying (QPSK), which is a digital modulation mode and is divided into two types, namely absolute phase Shift and relative phase Shift; another amplitude phase joint modulation (16QAM) with 16 samples is a digital high-order modulation, and the information amount of each symbol is 2 times of QPSK. 16QAM is a digital high-order modulation scheme, and compared to the general QPSK modulation scheme, 16QAM can more effectively utilize the channel bandwidth. Due to the introduction of a 16QAM high-order modulation mode, a higher authorization value needs to be introduced to meet the requirement of a higher rate.
The related technical background related to the invention also comprises: the Interconnection type B (IUB) interface is a logical interface between the radio network controller and the node B. The Node B Application Part (NBAP) protocol layer provides control signaling between the radio network controller and the Node B.
In the prior art, in engineering application, especially in an application scenario of 16QAM, the following performance problems may occur:
when the node B activates 16QAM operation of a radio link, the node B transmits an absolute grant with reference to the use table 1, and the node B transmits a relative grant with reference to the use table 4. Then problems can occur, which are described in detail as follows:
case 1) the node B transmits the absolute grant index 2 to the terminal, and with reference to the usage table 1, the absolute grant value corresponding to the index 2 is (7/15)2. Subsequently, the node B calculates an expected scheduling grant value according to the node B fast scheduling algorithm, compares the expected scheduling grant value with the reference power ratio/reference record saving power ratio, and hopefully decreases or down-adjusts the power ratio. However, at this time, since node B refers to the usage table 4, the minimum granularity of table 4 is (11/15)2And (11/15)2＞(7/15)2It is apparent that the node B cannot inform the terminal of DOWN through the relative grant.
Case 2) the node B transmits the absolute grant as the index number 31 to the terminal, and with reference to the usage table 1, the absolute grant value corresponding to the index number 2 is (168/15)2x 6. Subsequently, the node B calculates a desired scheduling grant value based on the node B fast scheduling algorithm, compares the desired scheduling grant value with a reference power ratio/reference record holding power ratio, and hopefully adjusts the power ratio upward, e.g., using 16QAM fully up to (377/15)2x 4. Then node B can only choose to use UP control signaling of relative grant to inform the terminal of the primary UP-regulation, but cannot use absolute grant directly, since the absolute grant value is now (168/15)2x6, already at the maximum particle size of table 1. Also, node B if it wishes to do so from (377/15)2x4 decreasing to (168/15)2x6, the terminal can only be informed of the first-level DOWN by relatively authorized DOWN control signaling. Each multi-stage processing is realized by adding at least one time of processing delay, which has a large influence on performance, cannot ensure that a corresponding terminal is timely scheduled through fast scheduling, and loses the significance of fast scheduling of a node B.

Detailed Description
The basic idea of the invention is: when the node B does not activate the 16QAM operation of the wireless link, the node B maps the absolute grant according to the first absolute grant value mapping relation table and processes the relative grant signaling according to the first scheduling grant table; and when the node B activates the uplink 16QAM operation of the wireless link, the node B maps the absolute grant according to the second absolute grant value mapping relation table and processes the relative grant signaling according to the second scheduling grant table.
The following describes the embodiments in further detail with reference to the accompanying drawings.
A processing method for determining relative grant and absolute grant mapping by a node B mainly comprises the following steps:
when the node B does not activate the uplink 16QAM operation of the radio link, the node B maps the absolute grant according to the first absolute grant value mapping table, such as table 1 (first absolute grant value mapping table), and processes the relative grant signaling according to the first scheduling grant table, such as table 3 (first scheduling grant table); when the node B activates the uplink 16QAM operation of the radio link, the node B maps the absolute grant according to the second absolute grant value mapping relationship table, such as the above table 2 (second absolute grant value mapping relationship table), and processes the relative grant signaling according to the second scheduling grant table, such as the above table 4 (second scheduling grant table).
Further, whether the node B activates uplink 16QAM operation of the radio link is indicated to the node B by the radio network controller sending NBAP layer control signaling to the node B.
Further, for the indication in the NBAP layer control signaling, when the NBAP layer control signaling carries the cell of the uplink 16QAM operation indication and the value of the cell is set to be active, the node B activates the uplink 16QAM operation of the wireless link; when the NBAP layer control signaling carries the cell of the uplink 16QAM operation indication and the value of the cell is set to be inactive, the node B does not activate the uplink 16QAM operation of the wireless link; when the NBAP layer control signaling does not carry the uplink 16QAM operation indication, then the node B does not activate uplink 16QAM operation of the wireless link.
Further, the node B maps the absolute grant according to the first absolute grant value mapping relation table, such as the above table 1 (first absolute grant value mapping relation table), which means that: the node B uses the first absolute grant value mapping table, such as the above table 1 (first absolute grant value mapping table), to find the index number corresponding to the absolute grant value in the table. The node B sends the absolute grant of the index number to the terminal to indicate the maximum uplink resource that the terminal can use, i.e., the maximum E-DPDCH/DPCCH power ratio for transmitting data in the activated HARQ process.
Further, the node B maps the absolute grant according to the second absolute grant value mapping relationship table, such as the above table 2 (second absolute grant value mapping relationship table), which means that: the node B uses the second absolute grant value mapping table, such as the above table 2 (second absolute grant value mapping table), to find the index number corresponding to the absolute grant value in the table. The node B sends the absolute grant of the index number to the terminal to indicate the maximum uplink resource that the terminal can use, i.e., the maximum E-DPDCH/DPCCH power ratio for transmitting data in the activated HARQ process.
Further, the node B processes the relative grant signaling according to the first scheduling grant table, such as the above table 3 (first scheduling grant table), which means that the node B refers to the first scheduling grant table, such as the above table 3 (first scheduling grant table), to send the relative grant of the service, where the relative grant of the service specifically includes 3 values, i.e., UP, HOLD, and DOWN. And, referring to the first scheduling grant table, the node B sends the non-serving relative grant, which specifically includes 2 values of HOLD and DOWN, as shown in table 3 (scheduling grant table one).
Further, the node B processes the relative grant signaling according to the second scheduling grant table, such as the above table 4 (second scheduling grant table), which means that the node B refers to the second scheduling grant table, such as the above table 4 (second scheduling grant table), to send the relative grant of the service, where the relative grant of the service specifically includes 3 values, i.e., UP, HOLD, and DOWN. And, referring to the second scheduling grant table, the node B sends the non-serving relative grant, which specifically includes 2 values of HOLD and DOWN, as described in the above table 4 (scheduling grant table two).
In summary, the solution of the present invention is different from the prior art that there is no correlation between tables, and the above-mentioned disadvantages in the prior art will occur when the tables are randomly matched for use, and the solution of the present invention is different from the prior art that a correlation is established between tables for use, so that the following obvious technical effects are achieved:
the node B associates and uses the first absolute grant value mapping relation table, such as table 1 (first absolute grant value mapping relation table), and the first scheduling grant table, such as table 3 (first scheduling grant table), and associates and uses the second absolute grant value mapping relation table, such as table 2 (second absolute grant value mapping relation table), and the second scheduling grant table, such as table 4 (second scheduling grant table), so that the node B accurately schedules and controls the power ratio available to the terminal, solves the performance problem discovered during the engineering operation, and improves the performance of the HSUPA technology in the engineering operation.
The invention is illustrated below.
Example 1:
as shown in fig. 1, the present embodiment includes the following steps:
step 110: the radio network controller sends NBAP layer control signaling to the node B.
Here, the NBAP layer control signaling carries the following information elements:
and carrying an uplink 16QAM operation indication cell, and setting the cell as an activated value.
