Method and device for processing uplink feedback information

Abstract

Disclosed are a method and device for processing uplink feedback information. When a plurality of carriers are configured for a receiving end to conduct aggregation, when the receiving end needs to send uplink feedback information in an uplink Pcell carrier and an uplink Scell carrier, and when subframes of uplink feedback information sent by the receiving end in the uplink Pcell carrier and the uplink Scell carrier are aligned, the receiving end sends both the uplink feedback information in the uplink Pcell carrier and the uplink Scell carrier through the uplink Pcell carrier; and when the subframes of the uplink feedback information sent by the receiving end in the uplink Pcell carrier and the uplink Scell carrier are not aligned, the receiving end respectively sends corresponding uplink feedback information in the uplink Pcell carrier and the uplink Scell carrier.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing uplink feedback information. Background technique [0002] Currently, when multiple carriers are configured for aggregation at the receiving end, the formats of the multiple carriers are usually the same, for example, all are frequency division duplex (Frequency Division Duplexing, FDD) or time division duplex (Time Division Duplexing, TDD) carriers , which is convenient for various processing during carrier aggregation. For example, when the receiving end is configured with multiple downlink and uplink carriers, the sending of uplink feedback information on the uplink carrier at the receiving end can be fed back at the same timing as the primary cell (Pcell) and the secondary cell (Scell), and the uplink feedback can be further restricted. The information is only sent to the network side on the Pcell. This helps to reduce the complexity of t...

Problems solved by technology

In this way, according to the existing protocol, when the receiving end needs to send uplink feedback information, it needs to send it in the subframe in the uplink Pcell, but if the TDD carrier is configured as the uplink Pcell of the receiving end at this time, and the uplink feedback information sending The Pcell corresponds to the TDD downlink subframe, so how to deal with it at the receiving end and how to deal with it at the network side, there is currently no specific technical support

[0005] In addition, due to the technical difficulty and poor actual effect of the receiving end transmitting data on multiple uplink carriers at the same time, most receiving ends do not have the ability to send data on multiple uplink carriers at the same time for a considerable period of time. On the terminal side, how to better support multi-carrier aggregation, especially when TDD and FDD are aggregated when TDD is Pcell, there is currently no specific technical support
