Definitions
- the present invention relates to the field of communications technologies, and in particular, to a subframe processing method and device. Background technique
- the CA Carrier Aggregation
- the multiple carriers that are not consecutive are aggregated together and serve the UE (User Equipment) when needed to provide the required rate.
- UE User Equipment
- a network side device such as a base station may simultaneously configure multiple working carriers for each UE, where one carrier is a primary carrier and the remaining carriers are secondary carriers.
- each secondary carrier can be configured on an unlicensed spectrum.
- the unlicensed spectrum generally refers to a common spectrum, that is, a spectrum that can be used by any organization or individual. Therefore, when the unlicensed spectrum is used, it is usually necessary to follow the rule of listening to the post, that is, listening. When the spectrum is idle, the signal can be sent on the unlicensed spectrum. That is to say, if the secondary carrier wave is deployed on the unlicensed spectrum, the use of the secondary carrier also follows the above-mentioned rules of listening and sending, so that the transmission of the secondary carrier may be discontinuous.
- the base station can generally use CCA (Clear Channel Assessment) to evaluate whether the channel occupied by the discontinuous carrier is idle, so as to determine whether the channel can be used.
- CCA Carrier Channel Assessment
- the CCA duration also referred to as channel listening duration or channel evaluation duration
- the base station uses the discontinuous carrier to transmit the signal for the longest time. It can't exceed 13ms (that is, the duration of the continuous carrier's channel can not exceed 13ms).
- the base station determines that the channel has not been used by other devices, the base station periodically occupies the channel, where the base station can be separated by CC A every two times. It can be seen from the foregoing that, for any UE, when there is a discontinuous carrier among the multiple working carriers configured for the UE, the discontinuous carrier will have a minimum duration of 20 ⁇ ⁇ (ie, CCA duration), and no signal can be sent.
- the UE does not know the time point of occurrence of the CCA, and thus the UE cannot remove the symbol occupied by the CCA from the entire subframe in which the CCA is located, resulting in The 14 symbols of the entire subframe where the CCA is located cannot transmit signals, which reduces the utilization of resources.
