Embodiment Construction

[0034] The scheme of the present invention provides how to configure the transmission of the SRS in the time domain, which specifically involves two parts: the configuration of broadcast signaling and the configuration of user-specific signaling. The scheme of the present invention can be applied to FDD and TDD systems.

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with specific examples.

[0036] Embodiment 1 of the present invention is a configuration scheme of broadcast signaling. As mentioned above, for both FDD and TDD systems, there is a conflict with PUSCH or PUCCH when sending SRS in conventional uplink subframes. Therefore, all UEs in the cell need to know which uplink subframes in the cell are configured with SRS transmission, so that When the PUSCH and PUCCH need to be sent in the subframe and collide with the SRS transmission, necessary...

Abstract

The invention discloses a method for collocating an uplink sounding reference signal (SRS), comprising the following steps: a base station determines an available SRS collocation period of a cell and determines the collocation position of an available SRS of the cell on a subframe under the determined SRS collocation period; and the base station performs joint coding to the determined SRS collocation period and the SRS collocation position and informs the result of the joint coding to all user equipment in the cell through a broadcast signaling. The invention also discloses a device for collocating the SRS. The scheme can realize the collocation on the SRS and can solve the problem that the SRS conflicts with uplink control information.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for configuring an uplink sounding reference signal. Background technique [0002] Uplink sounding reference signals (Sounding Reference signals, SRS) are uplink signals sent by user equipment (UE), and are used for measuring uplink channel quality. [0003] The existing SRS transmission can be configured as follows: for frequency division duplex (FDD) system and time division duplex (TDD) system, each UE supports 8 transmission cycles of 2ms, 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, and 320ms. For a TDD system, the SRS can be sent in an Uplink Pilot Time Slot (UpPTS) time slot. When the UpPTS length is 1 single carrier frequency division multiplexing symbol (SC-FDMA), the 1 SC-FDMA symbol can be used for SRS transmission; when the UpPTS length is 2 SC-FDMA symbols, the base station can configure two SC - FDMA symbols are all used for SRS t...
