However, LC-MTC UE can only measure a narrowband with a width of 6 PRBs, and after a measurement is completed, it needs at most one subframe to switch to another subband that needs to be measured

Embodiment Construction

[0026] Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] The LC-MTC service is characterized by a small amount of data but a large connection range. Therefore, eNB usually does not schedule specific LC-MTC UEs to other subbands because one LC-MTC UE does not bring much burden. With inter-user multiplexing, each subband can be well balanced, so it is possible to combine eNB-configured and UE-configured channel quality measurements into one option. This makes configuration easier and reduces overhead.

Abstract

The present disclosure provides a method and apparatus for channel quality measurement for an MTC UE, wherein the method performed at the MTC UE comprises: obtaining information on a sub-band measurement sequence of a plurality of sub-bands for which channel quality measurement is to be performed by the MTC UE; and during a measurement period, performing channel quality measurement on the plurality of sub-bands based on the sub-band measurement sequence.

Description

technical field [0001] The present invention generally relates to the field of wireless communication, and more specifically, relates to a method and device for channel quality measurement of MTC UEs. Background technique [0002] A machine type communication (Machine Type Communication, MTC) user equipment (UE) is a kind of UE dedicated to a machine. In 3GPP R12, a work item on Low Complexity MTC (Low Complexity MTC, LC-MTC) UE has been completed, wherein the complexity (cost) of MTC UE is reduced by about 50%. In R13, another work item tries to further reduce the complexity of the MTC UE, so as to enhance the coverage of the MTC UE and reduce power consumption. One technique for complexity reduction is to reduce the radio frequency bandwidth of low-complexity MTC UEs to 1.4 MHz (ie, operate in 6 Physical Resource Blocks (PRBs), where PRBs are resource allocation units in the frequency domain). It is expected that LC-MTC UEs can operate in any system bandwidth and can coe...
