Abstract
Methods, systems, and devices for wireless communication are described that support sounding reference signal (SRS) transmission in low latency wireless transmissions. A set of shortened transmission time intervals (sTTIs) for uplink transmissions of a first wireless service may be identified; the set of sTTIs located within subframe time boundaries of a subframe of a second wireless service with a longer TTI than the sTTIs. Two or more sTTIs within the set of sTTIs may be used for SRS transmissions within the subframe time boundaries.
Claims18
A method for wireless communication, comprising:
- receiving a configuration that indicates a set of short transmission time intervals (sTTIs) that are for uplink transmissions, wherein the set comprises a first subset of sTTIs being within a first slot, the first subset of sTTIs each spanning two orthogonal frequency division multiplexing (OFDM) symbols, and wherein the first subset of sTTIs comprises at least two consecutive OFDM symbols for transmission of sounding reference signal (SRS) transmissions;
- and
- transmitting one or more SRS transmissions in at least the at least two consecutive OFDM symbols.
An apparatus for wireless communication, in a system comprising:
- one or more processors;
- memory in electronic communication with the one or more processors;
- and
- instructions stored in the memory and operable, when executed by the one or more processors to cause the apparatus to:
- receive a configuration that indicates a set of short transmission time intervals (sTTIs) that are for uplink transmissions, wherein the set comprises a first subset of sTTIs being within a first slot, the first subset of sTTIs each spanning two orthogonal frequency division multiplexing (OFDM) symbols, and wherein the first subset of sTTIs comprises at least two consecutive OFDM symbols for transmission of sounding reference signal (SRS) transmissions;
- and
- transmit one or more SRS transmissions in at least the at least two consecutive OFDM symbols.
