Example Embodiment

[0026] The embodiment of the present invention provides a periodic SRS transmission indication method and base station, a periodic SRS transmission method and user equipment, which indicate the transmission mode of the periodic SRS through downlink signaling. The solution can be used for LTE-A or its evolution. Periodic SRS transmission of the system. The specific embodiments of the present invention will be described below with reference to the drawings.

[0027] In the description process, firstly, the implementation from the UE and the base station side will be explained separately, and then the cooperative implementation of the two will be explained, but this does not mean that the two must be implemented together. In fact, when the UE and the base station are implemented separately At that time, they also solve the problems on the UE side and the base station side respectively, but when the two are used in combination, better technical effects will be obtained.

Abstract

The invention discloses a transmission instruction, a transmission method and a device for a periodical detected reference signal, which comprise an adopted transmission mode when a base station confirms and requires a user device to transmit the periodical detected reference signal and an adopted transmission mode when the base station indicates the user device to transmit the periodical detected reference signal. The user device confirms the used transmission mode when the periodical detected reference signal is transmitted and transmits the periodical detected reference signal according to the confirmed transmission mode. Signaling cost is less, and more transmitting antenna switching can be supported.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a periodic SRS (Sounding Reference Signal, sounding reference signal) transmission instruction, transmission method and equipment. Background technique [0002] In an existing LTE (Long Term Evolution, long-term evolution) system, detection of an uplink channel is accomplished through a sounding (detection) signal. By sending the sounding signal at the last symbol of the SRS subframe, the base station can obtain uplink channel information, thereby performing resource scheduling for uplink transmission and measurement of various transmission parameters. The SRS in the LTE system is sent periodically, that is, the terminal will continue to send the sounding signal at a certain period until it enters a state of no data transmission. At the same time, although the terminal has two antennas in the LTE system, only one antenna can transmit the sounding signal at the same ti...
