example 1

[0056] The E-DCH channel can only be configured when the UE is in the CELL_DCH (cell_dedicated channel) state, such as image 3 As shown, the flow of the application example of the present invention for uplink signaling transmission includes the following steps:

[0057] In step 301, the UE initiates an RRC connection request through a random access channel (RACH, Random Access Channel), carrying establishment reasons, call types, and HSPA support capability indications. In this example, it is assumed that the UE supports HSPA;

[0058] Step 302, the RNC decides to move the UE into the CELL_DCH state through the RRM (Radio Resource Management) algorithm, and decides to configure E-DCH non-scheduling resources for the UE, so that uplink signaling can be transmitted on the E-DCH, and the signaling connection process is accelerated. When the RNC allocates physical resources related to E-DCH non-scheduled services to the UE, it needs to consider the radio resource configuration re...

example 2

[0070] This instance is only possible if both conditions are met:

[0071] 1) The network side broadcasts "HS-DSCH (High-Speed ​​Downlink Shared Transport Channel) public system information" in the cell system message (based on which the UE judges that the cell supports the CELL_FACH enhanced feature);

[0072] 2) UE supports HSDPA reception.

[0073] Such as Figure 4 As shown, the process of receiving downlink signaling on HSDPA by the application example of the present invention includes the following steps:

[0074] In step 401, the UE initiates an RRC connection request, which includes the reason for establishing the connection, the call type (voice, video stream, etc.) and whether it supports HSPA capability information. In this example, the capability indication carried by the UE can be "only supports HSDPA" or " Support HSDPA and E-DCH". The HSDPA physical layer capability category of UE in TD-SCDMA is divided into 15 categories, as shown in Table 4:

[0075] ...

example 3

[0083] Another application scenario is how to receive signaling and data through HSDPA after a connected UE enters a new cell through cell reselection (there is no uplink transmission after the UE enters a new cell through cell reselection, because the UE is working at this time) In the CELL_FACH state, the E-DCH service cannot be used). Same as the second example, this example is only meaningful when the cell supports the enhanced feature of CELL_FACH and the UE supports HSDPA reception. Such as Figure 5 As shown, the process of receiving downlink signaling on HSDPA after cell reselection of the application example of the present invention includes the following steps:

[0084] In step 501, the UE initiates a cell update request through cell reselection. In the existing protocol, when the UE initiates a cell update in a new cell, it carries an indication of whether it supports HSPA;

[0085] Step 502, when the RNC on the network side finds that the UE supports HSDPA, it c...

Abstract

The invention discloses a method for transmitting signaling at high speed packet access channel. Initial signaling is transmitted in third generation mobile communication system, sending party determines HSPA transmission parameter according to lowest HSPA physical layer ability category defined by the system, and sends the transmission parameter to receiving party through control channel before network side has acquired high speed packet access HSPA ability category of user terminal UE; the receiving party resolves the transmission parameter according to lowest HSPA ability category defined by the system. The inventive simple and practical method can be applied to transmitting signal on HSPA before network ((RNC adn Node B) has completely acquired HSPA physical layer ability category of UE, solve problem of background information by establishing protocol agreement of UE side and network side without modifying interface protocol.

Description

technical field [0001] The invention relates to a 3G (Third Generation, third generation) communication system in the field of wireless communication, in particular to a method for transmitting signaling on a high-speed packet access channel. Background technique [0002] HSPA (High Speed ​​Packet Access) includes two major technologies in the protocol system of 3GPP (3rd Generation Partnership Project, the third generation mobile communication partner organization), that is, HSDPA (High Speed ​​Downlink Packet Access) formulated in Rel-5 version , High Speed ​​Downlink Packet Access) technology and E-DCH (Enhanced Dedicated Channel, Enhanced Dedicated Channel) technology formulated in Rel-6 version, usually called HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) technology. The introduction of HSPA technology has greatly enhanced the data service bearing capacity of the 3GPP3G network, and the spectrum utilization rate has also been significantly...
