Embodiment 1
[0314] This embodiment relates to a method of channel and signal transmission, which is used for a machine type communication MTC terminal, such as figure 1 As shown, its process includes:
[0315] Step 110, predefine or according to the received signaling, obtain the resource area that can be used to send uplink physical channels and uplink signals;
[0316] Step 120, sending the uplink physical channel and uplink signal in the resource area.
[0317] Wherein, the uplink physical channel and uplink signal include:
[0318] Physical Uplink Shared Channel (PUSCH for short);
[0321] Wherein, in the context of the present invention, unless otherwise specified, the type of terminal (UE) is an MTC terminal (also referred to as a bandwidth-reduced MTC terminal). In addition, unless otherwise specified, the PUSCH, PUCCH and SRS in the...
Embodiment 2
[0478] This embodiment relates to a channel and signal transmission method, which is used for base stations capable of performing MTC, such as Figure 10 shown, including:
[0479] Step 210, predefine or indicate through signaling a resource area that can be used to send uplink physical channels and uplink signals;
[0480] Step 220, receiving the uplink physical channel and uplink signal sent by the MTC terminal in the resource area.
[0481] Wherein, the uplink physical channels and uplink signals include: a physical uplink shared channel PUSCH, a physical uplink control channel PUCCH and a sounding reference signal SRS.
[0482]Preferably, the pre-definition or signaling indicates resource areas that can be used to send uplink physical channels and uplink signals, including:
[0483] Predefine or indicate through signaling that the resource area available for sending PUSCH is N determined in the system bandwidth PUSCH a PUSCH subband;
[0484] Predefine or indicate thro...

Abstract
A channel, signal transmission method and corresponding terminal and base station: an MTC terminal acquires a resource area for transmitting an uplink physical channel and an uplink signal through predefinition or according to a received signaling; transmitting the uplink physical channel and the uplink signal in the resource area; correspondingly indicating a resource area for transmitting the uplink physical channel and the uplink signal by a pre-defined MTC base station or via signaling instruction; in the resource area, receiving the uplink physical channel and the uplink signal transmitted by the MTC terminal, the uplink physical channel and the uplink signal comprising a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH) and a sounding reference signal (SRS). The technical solution of the present invention ensures normal transmission of each uplink physical channel and each uplink signal of the MTC terminal having reduced uplink transmission bandwidth, and can avoid greater loss of transmission performance.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular, to a method for transmitting an uplink physical channel and an uplink signal, as well as a corresponding terminal and a base station. Background technique [0002] Machine Type Communication (MTC for short) User Equipment (UE for short), also known as Machine to Machine (M2M for short) user communication equipment, is the main application form of the Internet of Things at this stage. Low power consumption and low cost are important guarantees for its large-scale application. Smart metering (Smart Metering) devices are one of the most typical applications of MTC devices. Currently, the M2M devices deployed in the market are mainly based on the Global System of Mobile communication (GSM for short) system. [0003] In recent years, due to the high spectral efficiency of the Long Term Evolution (LTE) system, more and more mobile operators have determined that LTE will be...
