Random access with full coverage on selected resources

Apparatus for ensuring random access coverage in one cell while supporting high uplink data rates in the one call served by a base station, comprising:

• programmable logic circuitry configured to:
• identify a shared set of radio resources associated to the one cell to be shared by multiple mobile radio terminals for uplink transmissions to the base station including requests for access to service from the base station and transmissions for active connections with the base station, and
• define a first repeating time period for the one cell and a second repeating time period for the one cell different from the first repeating time period;
• a scheduler configured to schedule:
• uplink transmission grants during the first repeating time period for one or more active connections being supported by the one cell that permit use of a greater amount of the shared set of radio resources associated to the one cell, and
• uplink transmission grants during the second repeating time period for one or more active connections being supported by the one cell that permit use of a smaller amount of the shared set of radio resources associated to the one cell smaller than the greater amount;
• and
• a controller configured to control at least some random access requests served by the one cell to the base station to occur only during the second repeating time period.
