Description

Configuration system and method for high-speed uplink packet access same-frequency adjacent cell in multi-carrier system

Technical Field

The invention relates to a Time Division synchronous Code Division Multiple Access (TD-SCDMA) technology in the field of mobile communication, in particular to a configuration system and a method of High Speed Uplink Packet Access (HSUPA) same frequency adjacent cells in a TD-SCDMA multi-carrier system.

Background

The physical channels related to the TD-SCDMA Enhanced-Uplink Dedicated Channel (E-DCH) include: an Enhanced Uplink physical Channel (E-PUCH), an Enhanced Uplink Control Channel (E-UCCH), an Enhanced Uplink hybrid Automatic Repeat ReQuest Acknowledgement Indicator Channel (E-DCH Automatic Repeat ReQuest Indicator Channel (E-HICH), and an Enhanced Uplink Absolute Grant Channel (E-DCH Absolute Grant Channel (E-AGCH)).

The enhanced uplink access service is divided into a scheduling service and a non-scheduling service according to different scheduling modes, wherein the resource of the non-scheduling service is allocated to the UE by a Radio Network Controller (RNC for short), and the allocation mode is the same as the existing dedicated channel allocation mode; in the scheduling service, the RNC allocates an enhanced uplink resource pool to a Node B (nodeb), and the Node B allocates resources to a single UE.

In the scheduling service, the UE needs to report some information to assist the scheduling of the Node B, where the information is called scheduling information si (scheduling information), and includes UE buffer information, power headroom, path loss measurement information of the local cell and neighboring cells, and the like, and there are 23 bits in total. The contents of the scheduling information are shown in table l.

(4bits)

Wherein the total buffer status is the total of the data amount to be sent in the UE logical channel buffer; the state of the highest priority logic channel is the data volume of a buffer area corresponding to the highest priority logic channel with data to be sent currently; the highest priority logical channel ID specifically indicates the highest priority logical channel number for which data is to be sent. These three parameters allocate appropriate resources for Node B as reference, including channel resources and power resources. Service and neighbor Cell path loss (SNPL) provides reference for controlling interference to neighbor cells for Node B; the uplink power headroom is the transmit power currently available to the UE. When the UE has authorized E-PUCH resources, the scheduling information and the service data are transmitted together through the E-PUCH channel, and when the UE has no authorization, the SI transmits the scheduling information through the E-RUCCH channel.

For the multi-carrier TD-SCDMA system, because the user can work at the auxiliary carrier frequency, the same frequency and different frequency definitions in the measurement are defined according to the relation between the adjacent main frequency point and the user working frequency point, that is, if the adjacent main frequency point and the user working frequency point are the same, the adjacent main frequency point is regarded as the same frequency adjacent region, and if the adjacent main frequency point and the user working frequency point are different, the adjacent main frequency point is regarded as the different frequency adjacent region. SNPL is measurement on adjacent regions with the same frequency, but for a TD-SCDMA multi-carrier system, only the main frequency point can not be considered as the adjacent region with the same frequency, and when the auxiliary frequency point in the adjacent region is the same as the working frequency point of a user, the auxiliary frequency point also needs to be taken into a measurement object of SNPL. Currently, the RRC protocol notifies the UE whether the neighboring cell has an auxiliary frequency point that is the same as the current working frequency point through a system broadcast message and a measurement control message, as shown in table 2:

				...

The pilot frequency adjacent cell in table 2 has a cell "auxiliary carrier frequency co-frequency indication" for indicating that there is a frequency point the same as the current working frequency point of the user among the auxiliary frequency points of the pilot frequency adjacent cell, and through the indication bit, the UE knows that the adjacent cell needs to be measured when calculating SNPL.

For single carrier HSUPA, such an indicator bit is not problematic, but for multi-carrier HSUPA, the UE will send data at multiple carrier frequencies, and will report SNPL at multiple carrier frequencies, then a problem will occur, and is the co-frequency point identified by this indicator bit co-frequency with which HSUPA frequency point? Need to consider the neighboring cell path loss in the SNPL information of which HSUPA frequency point? The existing common-frequency neighbor cell list has no similar indication field, and the common-frequency neighbor cell only indicates that the main carrier frequency of the neighbor cell is the same as the working frequency point of the UE and can not indicate whether the auxiliary frequency point of the neighbor cell has the same frequency point as the multi-carrier HSUPA frequency point. The network side cannot obtain accurate SNPL information, it is very difficult to allocate appropriate resources to the UE, and the resources are not properly allocated, which may affect the quality of service on one hand and may cause large interference on the other hand.

It should be understood by those skilled in the art that the formats of the inter-frequency neighboring cells shown in table 3 and table 4 are specific examples listed for illustrating the scheme of the present invention, and are not intended to limit the present invention.

Step 102: and the UE performs neighbor cell measurement according to the acquired same frequency information of the multi-carrier HSUPA to obtain SNPL, and reports the SNPL to the NodeB.

Specifically, when the UE reports SNPL on an HSUPA carrier, if it is known from the common-frequency information of the multi-carrier HSUPA that a neighboring cell has a frequency point having the same frequency as the HSUPA carrier, the neighboring cell is considered as a cell in a neighboring cell monitoring list, and the UE calculates SNPL according to the path loss of each neighboring cell in the neighboring cell monitoring list and the path loss of the serving cell, and reports the calculated SNPL to the NodeB.

The format shown in table 5 is formed based on the format specified by the protocol, except that "HSUPA carrier packet" and "same SNPL monitor cell carrier indication" are added, which are indication bits used by the RNC to notify the NodeB neighbor cell information.

It should be understood by those skilled in the art that the format of the inter-frequency neighboring cell shown in table 5 is a specific example listed for illustrating the scheme of the present invention, and is not intended to limit the present invention.

the wireless network controller uses n bits to represent the multi-carrier same-frequency indication, and each bit represents whether a carrier capable of sending an enhanced uplink physical channel (E-PUCH) has a frequency point with the same frequency in a neighboring cell; the n bits are arranged according to the sequence of the HSUPA carrier frequency points from large to small or from small to large;

13. The system according to claim 12, wherein the fact that whether the same-frequency points exist in the neighboring cell of the carrier that can send the E-PUCH represented by each bit is:

14. The system of claim 10, wherein:

15. The system of claim 10, wherein:

the system further comprises a base station;

16. The system of claim 15, wherein:

the SNPL monitoring neighbor cell information notification of the multi-carrier HSUPA means that HSUPA carrier grouping and the same SNPL monitoring neighbor cell carrier indication are added in an Iub port message by the wireless network controller;

the HSUPA carrier grouping indicates the number of divided carrier groups;

17. The system of claim 16, wherein:

the wireless network controller uses n bits to represent the indication of the carrier waves of the same SNPL monitoring neighbor cell, and when each carrier wave with the bit value of 1 belongs to the same carrier wave group; or, using n bits to represent the indication of the carriers in the same SNPL monitoring neighboring cell, and when each carrier with a bit value of 0 belongs to the same carrier group;

the n represents the maximum number of carriers supported by the cell.

18. The system of claim 15, wherein:
