Embodiment 1

[0046] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, figure 1 It is a hardware structural block diagram of a mobile terminal of a signal transmission method in an embodiment of the present invention. Such as figure 1 As shown, the mobile terminal 10 may include one or more (only one is shown in the figure) processor 102 (the processor 102 may include but not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA, etc.), for A memory 104 for storing data, and a transmission device 106 for communication functions. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device. For example, the mobile terminal 10 may also include figure 1 more or...

specific Embodiment 1

[0082] This specific embodiment 1 comprises the following steps:

[0083] Step 1: the terminal receives the signal sent by the base station at the first time-frequency position, and the terminal detects the received signal;

[0084] Step 2: Determine the detection of the physical downlink channel according to the signal detection result.

specific Embodiment 1a

[0086] This specific embodiment 1a comprises the following steps:

[0087] Step 1: the terminal receives the signal sent by the base station at the first time-frequency position, and the terminal detects the received signal;

[0088] Step 2: When the terminal detects that the corresponding signal is the first signal, the terminal detects the physical downlink channel, and when the terminal detects that the corresponding signal is the second signal, the terminal does not detect the physical downlink channel.

Abstract

The invention provides an information transmission method and device. The method includes the steps that a terminal receives a signal sent by a base station at a preset first time-frequency location,detects the signal, and determines the detection of the physical downlink channel according to the signal detection result. That is, the terminal determines to detect the physical downlink channel according to whether the detection result of detecting the signal meets a pre-agreed rule. The above solution solves the problem that the power consumption of a terminal is increased in the related technologies due to a condition that the number of times that a terminal detects a physical downlink channel is too large.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an information transmission method and device. Background technique [0002] In related technologies, Machine Type Communications (Machine Type Communications, MTC for short), also known as Machine to Machine (M2M for short), is a main application form of the Internet of Things at the present stage. MTC devices currently deployed in the market are mainly based on the Global System of Mobile communication (GSM for short) system. In recent years, due to the high spectrum efficiency of LTE / LTE-A, more and more mobile operators choose LTE / LTE-A as the evolution direction of future broadband wireless communication systems. MTC multi-type data services based on LTE / LTE-A will also be more attractive. [0003] In the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) technical report TR45.820V200, several technologies applicable to the cellu...
