Embodiment Construction

[0015] Please refer to FIG. 1 , which is a functional block diagram of a wireless communication device 100 . For simplicity, FIG. 1 only shows an input device 102 , an output device 104 , a control circuit 106 , a CPU 108 , a storage device 110 , a program code 112 and a transceiver 114 of the wireless communication device 100 . In the wireless communication device, the control circuit 106 executes the program code 112 stored in the storage device 110 through the central processing unit 108, thereby controlling the operation of the wireless communication device 100, and can receive the signal input by the user through the input device 102 (such as a keyboard), Or output signals such as picture and sound through the output device 104 (such as a screen, a speaker, etc.). The transceiver 114 is used to receive or send wireless signals, transmit the received signals to the control circuit 106 , or output the signals generated by the control circuit 106 by radio. In other words, i...

Abstract

The invention provides a method of stopping a multi-input multi-output (MIMO) operation for a user equipment (UE) of a wireless communication system to ensure that the UE can receive downlink data after the MIMO operation is stopped. The method includes indicating the physical layer and media access control layer of the UE to stop the MIMO operation when a reconfiguration message received from a network terminal does not include a MIMO parameter information element (IE) for carrying MIMO configuration data.

Description

technical field [0001] The present invention relates to a method for improving the MIMO function of a wireless communication system and its related device, in particular to a method for disabling a MIMO function in a user end of the wireless communication system and its related device. Background technique [0002] The third-generation mobile communication technology adopts the wireless access method of Wideband Code Division Multiple Access (WCDMA), which is used to provide high spectrum utilization efficiency, wide-ranging coverage and high-quality, high-speed Multimedia data transmission can better meet various QoS service requirements, provide flexible and diversified two-way transmission services, provide better communication quality, and effectively reduce communication interruption rate. Through the third-generation mobile communication system, users can use wireless communication devices (such as mobile phones) to realize real-time image communication, conference cal...
