1. A method comprising:
- incorporating sounding reference signal presence information into an uplink data resource assignment for a user equipment; and
sending the uplink data resource assignment including the sounding reference signal presence information to the user equipment,wherein the sounding reference signal presence information consists of a single bit in the uplink data resource assignment,wherein the uplink data resource assignment allocates frequency and time resources to the user equipment for use in uplink signalling,wherein the sounding reference signal presence information indicates whether or not a sounding reference signal is present in the frequency and time resources allocated to the user equipment, andwherein a frequency band allocated to the user equipment comprises a plurality of allocated data symbols and one of allocated data symbols is designated as a signal for sounding reference signalling.
