Technical Field

The present invention relates to the field of communications technologies, and in particular, to a subframe processing method and device.

Background

In an LTE (Long Term Evolution ) system or an LTE-a (LTE-Advanced, enhanced Long Term Evolution) system, in order to improve the uplink and downlink peak rates of the system, a CA (Carrier Aggregation) technology is introduced, that is, a plurality of continuous or discontinuous carriers are aggregated together, and simultaneously serve a UE (User Equipment) when necessary, so as to provide a required rate. Through the CA technology, the resource utilization rate can be maximized, and discrete spectrum resources can be effectively utilized.

Specifically, in the CA technology, a network side device such as a base station may configure multiple working carriers for each UE at the same time, where one carrier is a primary carrier and the rest of the carriers are secondary carriers. Moreover, in order to maximize resource utilization, each secondary carrier may be configured on an unlicensed spectrum. Since the unlicensed spectrum generally refers to a public spectrum, that is, a spectrum that can be used by any organization or person, it is generally necessary to follow a listen-before-send rule when using the unlicensed spectrum, that is, when the spectrum is sensed to be idle, signals can be transmitted on the unlicensed spectrum. That is, if the secondary carrier is deployed on the unlicensed spectrum, the secondary carrier is also used according to the rule of listen before transmit, so that the transmission of the secondary carrier may be discontinuous.

Specifically, for a discontinuous carrier deployed on a frequency spectrum such as an unlicensed spectrum, a base station may generally evaluate whether a Channel occupied by the discontinuous carrier is idle through CCA (Clear Channel Assessment) so as to determine whether the Channel may be used. Generally, the minimum length of the CCA duration (also referred to as channel sensing duration or channel estimation duration) occupied by the base station for CCA is not less than 20s, and the maximum length of the duration for each time that the base station transmits a signal by using the discontinuous carrier cannot exceed 13ms (that is, the maximum length of the continuous channel occupancy duration of the discontinuous carrier cannot exceed 13 ms). Furthermore, if the base station determines that the channel has not been used by other devices, the base station may periodically occupy the channel, wherein the CCA may be used to separate the occupation time of the channel from each other.

As can be seen from the above, for any UE, when there is a discontinuous carrier in a plurality of working carriers configured for the UE, the discontinuous carrier may have a duration (i.e., a CCA duration) of at least 20s and cannot transmit any signal, although the CCA duration may occupy less than one symbol of a subframe, since the UE does not know the time point at which the CCA occurs, the UE cannot exclude the symbol occupied by the CCA from the whole subframe in which the CCA is located, and 14 symbols of the whole subframe in which the CCA is located cannot transmit signals, thereby reducing the utilization rate of resources.
