1. A method for wireless communication, comprising:
transmitting, by a network node, a configuration comprising A orthogonal code sequences for a sounding reference signal (SRS) resource, wherein each of the A orthogonal code sequences is configured for L adjacent SRS symbols within the SRS resource, wherein L is a length of each of the A orthogonal code sequences, wherein L and A are positive integers,
wherein the A orthogonal code sequences for the SRS resource are configured by a high-level message comprising Radio Resource Control (RRC) signaling or Medium Access Control (MAC) Control Element (CE) signaling, wherein A is equal to N/R, N/L or R/L, wherein N is a number of SRS symbols in the SRS resource and R is a repetition factor, wherein R and N are positive integers,
wherein the configuration further comprises B indications of whether basic sequences of L, R or N SRS symbols within the SRS resource are repeated, wherein the basic sequences are sequences of the L, R or N SRS symbols before the A orthogonal code sequences are applied to the L, R or N SRS symbols, wherein B is a positive integer, wherein B≤A, and
wherein the A orthogonal code sequences applied to the SRS symbols are based on a time-varying pattern, wherein the time-varying pattern is (1) predetermined or (2) configured using Radio Resource Control (RRC) signaling or Medium Access Control (MAC) Control Element (CE) signaling; and
receiving, by the network node from a wireless device, a reference signal that is generated based on the configuration.
