Embodiment 1

[0049] According to an embodiment of the present invention, an embodiment of a channel selection method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, although in The logical sequence is shown in the flowchart, but in some cases, the steps shown or described may be performed in a different order than here.

[0050] image 3 Is a flowchart of a channel selection method according to an embodiment of the present invention, such as image 3 As shown, the method includes the following steps:

[0051] Step S302, indicating the time domain resource location and the frequency domain resource location of the enhanced physical uplink control channel region based on a common physical downlink control channel (CommonPDCCH, C-PDCCH for short);

[0052] Step S304: Instruct a group of user terminals to transmit the enhanced physical uplink control channel ...

Embodiment 2

[0092] In the channel selection method provided in the embodiment of the present invention, the time domain resource position and the frequency domain resource position of the enhanced physical uplink control channel (ePUCCH) are indicated through the common physical downlink control channel (C-PDCCH), specifically:

[0093] Step S1, indicating the time domain position of the enhanced physical uplink control channel region.

[0094] Specifically, it includes: the Nth subframe after the subframe in which the common physical downlink control channel is sent is the subframe where the enhanced physical uplink control channel region is located, where N is RRC configuration or pre-defined; or according to the data carried on the common physical downlink control channel The Nth subframe after the current subframe indicated by the downlink control information DCI is the subframe where the enhanced physical uplink control channel region is located.

[0095] Step S2, indicating the frequency d...

Abstract

The invention discloses a method and a device for selecting a channel. The method comprises the steps of indicating time domain resource positions and frequency domain resource positions of enhanced physical uplink control channel areas based on a public physical downlink control channel; indicating a group of user terminals to transmit enhanced physical uplink control channels within the indicated enhanced physical uplink control channel areas, wherein different user terminals transmit the enhanced physical uplink control channels within the indicated different enhanced physical uplink control channel areas. The method and the device solve the technical problem of too high downlink signaling overhead caused by uplink scheduling authorization when a large number of users transmit data in the enhanced physical uplink control channels in the prior art.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for channel selection. Background technique [0002] The existing mobile communication system means that operators deploy radio access network equipment (such as base station, evolvedNodeB, eNB for short) and core network equipment (such as home location register, HomeLocation Register, or HLR for short) to provide user terminals (such as mobile phones). ) A system that provides communication services. Mobile communication has undergone the evolution of the first, second, third and fourth generations. Among them, the first generation of mobile communication refers to the original analog, voice-only cellular phone standard, which mainly uses analog Technology and frequency division multiple access (Frequency Division Multiple Access, referred to as FDMA) access method; the second generation of mobile communications introduced digital technology, which incr...
