Problems solved by technology

Since the Node B does not store the context communication semantics of the UE in the non-CELL_DCH state, even if the RNC allocates a dedicated H-RNTI for the UE, the Node B does not know the specific information of the UE corresponding to the H-RNTI (such as the maximum receiving capacity) resources), during scheduling, if the allocated resources are too large, the UE corresponding to the H-RNTI will not be able to receive it, resulting in a waste of system resources. Scheduling will inevitably lead to a decrease in system efficiency
[0011] Therefore, it would be ideal if the Node B can perform scheduling according to the specific capabilities of the UE. However, the current CELL_FACH and CELL_PCH enhancement mechanisms lack the basis for flexible scheduling, and how the Node B can obtain the specific capabilities of the UE has not yet been solve

example 1

[0042] In one cell, one common H-RNTI corresponds to multiple UEs, but in one HS-DSCH TTI (Transmission Time Interval), one common H-RNTI only corresponds to one UE. Even if the RNC allocates a dedicated H-RNTI for the UE, the Node B cannot know the specific information of the UE. When the RNC sends the public MAC flow data frame to the Node B, it will bring the H-RNTI of the UE to which the data frame should point, so the HS-DSCH physical layer capability information of the UE can be brought to the Node B in the data frame.

[0043] Therefore, in this example, the RNC carries the wireless access capability information of the UE through the data frame of the Iub port. Specifically, the RNC carries the information of the UE corresponding to the H-RNTI in the same data frame through the idle bits in the data frame of the Iub port. Wireless access capability information.

example 2

[0047] In Example 1, the user plane frame protocol is used to transmit related UE capability information, which can achieve real-time effect. However, if more user information is desired to be transmitted, it needs to be transmitted through the control plane. A disadvantage of transmission on the control plane is that transmission delay may cause asynchrony with the data frame, and the RNC needs to ensure that the capability information is sent to the Node B before transmitting the MAC flow data of the UE.

[0048] Therefore, in this example, the RNC can transmit the radio access capability information of the UE to the NodeB through the control plane signaling of the Iub interface. In the current Iub control plane NBAP (Node B Application Part) protocol, for UEs in CELL_FACH and CELL_PCH states, there is no need to create a dedicated communication interface between RNC and Node B, and only need to send control plane signaling on the common communication port (Including: user ...

Abstract

The invention provides a method for indicating user equipment (UE) capacity under a non-CELL_DCH state, wherein a radio network controller (RNC) indicates the radio access capacity information of a user terminal which is to receive data when transmitting the data mapped on a HS-DSCH under the non-CELL_DCH state. By using the method, a Node B can know the specific UE capacity and schedule according to the UE capacity, so as to reasonably schedule and allocate resources.

Description

technical field [0001] The invention relates to the scheduling control of HS-DSCH resources in the non-CELL_DCH state in the field of wireless communication, and more specifically, relates to a user equipment capability indication method in the non-CELL_DCH state. Background technique [0002] At present, 3GPP (Third Generation Partnership for Mobile Communications) has completed the standardization work of CELL_FACH state (cell_forward access channel state) enhancement in WCDMA (Wideband Code Division Multiple Access) system. The CELL_FACH state enhancement technology introduces the HS-DSCH (High Speed ​​Downlink Shared Transport Channel) transmission channel in the CELL_FACH state to enhance the packet data transmission performance of this state, so that it can obtain smaller packet transmission delay and higher rate. In addition, the HS-DSCH transport channel is also introduced into the CELL_PCH (Cell_Paging Channel) state. [0003] In versions prior to 3GPP REL-7, the H...
