Embodiment Construction

[0087] Before describing the embodiments of the present invention in detail, the principles involved in the embodiments of the present invention will be described in detail, so as to better understand the embodiments of the present invention.

[0088] First, after the terminal sends an SR to request resources each time, the base station will allocate uplink traffic channel (PUSCH) resources, and the channel measurement function of the pilot on the PUSCH is basically the same as the SRS measurement function.

[0089] Secondly, in the TD-LTE system, the uplink and downlink channels are completely equal, so the SRS measurement of the uplink channel can rely on the terminal to supplement the channel quality index (CQI) fed back by the downlink channel measurement.

[0090] Finally, when detecting whether SRS resources are sent, the base station has already obtained the prior information related to the period and delay of the terminal when the terminal accesses, so the detection acc...

Abstract

The invention provides a communication processing method, device, terminal and base station. When the method is applied to the terminal, SR resources are multiplexed on SRS resources. The method comprises the steps of judging sending requests of the SR and the SRS of a current subframe, and obtaining a judging result; sending the subframe to the base station directly when the judging result indicates that the current subframe needs to send the requests of the SRS and the SR at the same time; sending the subframe carrying the SRS information to the base station when the judging result indicates that the current subframe does not need to send the SR and needs to send the SRS, enabling the base station to carry out detection on the subframe when the subframe is received, and using the SRS information to carry out uplink channel measurement when the fact that the subframe carries the SRS information is detected; otherwise, carrying out an uplink service channel resource allocation process, and carrying out channel measurement by utilizing pilot frequency on service channels. According to the communication processing method, device, terminal and base station, the feedback mode that HARQ multiplexes the SR is prevented from being used, and the sending of the requests of the SR is guaranteed at the same time.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication processing method, device, terminal and base station. Background technique [0002] In the current TD-LTE system, in order to guarantee the traffic, the hybrid automatic repeat request (HARQ) technology is used. The basic process of HARQ work is: the transmitting end connects one or more data units in series, encodes them according to the physical layer protocol, and generates multiple HARQ subpackets. The transmitting end only transmits one subpacket at a time, and the receiving end does not need to obtain all Subpackages can also be decoded correctly. When the receiving end receives the first subpacket, it tries to decode it. If the decoding fails, it returns an acknowledgment (ACK) message to the base station to prevent sending subsequent subpackets; if the decoding fails, it returns a denial information (NACK), please transmit the next subpacket at the tran...
