Problems solved by technology

For optimized MTC equipment, in order to reduce the cost of the terminal, the capability of the terminal is limited to its own supported bandwidth. If this type of terminal enters a cell whose system bandwidth is larger than its own supported bandwidth, it cannot send measurement and decoding information related to downlink data and Uplink control information such as uplink data arrival information causes the terminal to fail to work normally

Embodiment 1

[0094] In this embodiment, the uplink control signaling of the M2M terminal is carried by two channels, the PUCCH and the PUSCH.

[0095] When the bandwidth supported by the M2M terminal is smaller than the bandwidth of the LTE system, the uplink control signaling of the M2M terminal is carried in the uplink data (PUSCH) area of ​​the LTE system, such as Figure 5 shown. The bearer mode and other mechanisms adopted may be the same as those of the existing LTE system and have compatibility, that is, the uplink control signaling of the M2M terminal is carried in two ways, the PUCCH and the PUSCH.

[0096] Wherein, the working bandwidth of the MTC device may be at a high frequency position, a low frequency position or a center frequency position within the system bandwidth. Figure 5 Indicated by the position of the center frequency. The advantage of this embodiment is that it will not affect the control area of ​​the existing LTE system, thus not affecting the sending and rece...

Embodiment 2

[0098] In this embodiment, the uplink control signaling of the M2M terminal is still carried by two channels, the PUCCH and the PUSCH. The bandwidth position of the M2M terminal is continuous with the PUCCH resource of the current LTE system in the frequency domain, such as Image 6 and Figure 7 As shown, the transmission resource occupied by the uplink control signaling of the MTC device may be continuous with the high-frequency or low-frequency PUCCH resource in terms of frequency. In order to ensure that resources are continuous and the location of M2M resources is known, a known number of PUCCH resources can be reserved for the LTE system, and the resources can be configured semi-statically through high-layer signaling.

[0099] The advantage of this embodiment is that it will not cause too many uplink resource fragments in the existing LTE system, and it can ensure that the terminal users of the existing LTE system can transmit large-bandwidth uplink data, and have litt...

Embodiment 3

[0101] In this embodiment, the uplink control signaling of the M2M terminal can be carried on the data channel and the control channel, and the data channel carrying mode can be the same as the existing mechanism.

[0102] In addition, the uplink control signaling of the M2M terminal can be carried on the control channel, and the control channel is located at one end of the frequency band within the operating bandwidth of the MTC device, such as Figure 8 and Figure 9 shown.

[0103] Assuming that the new control channel is named X-PUCCH, then:

[0104] One way for the X-PUCCH control channel to carry control signaling is to use the PUCCH mapping and multi-user multiplexing coding methods of the existing LTE system, but instead of frequency hopping within the entire system bandwidth, it can hop within the resources occupied by the PUCCH frequency.

[0105] Another way for the X-PUCCH control channel to carry control signaling is to use the PUSCH mapping and multi-user mult...

Abstract

The invention discloses a transmission method and device of an uplink control signaling, aiming to realize the purpose that the terminal can transmit the uplink control signaling of the terminal in a cell of which the system bandwidth is larger than the bandwidth supported by the terminal through the uplink control signaling of an LTE (long term evolution) system transmission terminal, and the terminal can be guaranteed to work normally. The sending method of the uplink control signaling, which is provided by the invention, comprises the following steps: determining an uplink control signaling required to be sent of the terminal; and sending the uplink control signaling of the terminal by an uplink data domain of the LTE system or an uplink data domain and an uplink control domain of the LTE system.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for transmitting uplink control signaling. Background technique [0002] In the third generation mobile communication system and its long-term evolution system, it is necessary to support a machine type communication (Machine Type Communications, MTC) function. An MTC device (that is, an MTC device) may have some of the characteristics of a variety of machine-to-machine (M2M) communication, such as: low mobility, small amount of transmitted data, insensitive to communication delay, requiring Features such as extremely low power consumption. [0003] Bandwidth is an important factor affecting the cost of MTC equipment. If the working bandwidth of MTC equipment can be appropriately reduced, the cost will be significantly reduced. At present, the maximum system bandwidth of all protocol version systems of Long Term Evolution (LTE) technology is...
