Apparatus and method for communicating signaling information
First Claim
1. An apparatus transmitting signaling information in a cellular communication system having a plurality of shared uplink transmission resources divided into sets of mutually exclusive transmission resources;
- the apparatus comprising;
uplink scheduler for granting an uplink transmission resource to a wireless subscriber communication unit via a grant message;
receiver for receiving an uplink transmission previously scheduled from a wireless subscriber communication unit, wherein the uplink transmission is previously scheduled by the uplink scheduler;
means for deriving an uplink code resource identifier associated with the uplink transmission or the grant message;
transmit code controller for assigning at least one downlink code sequence associated with the derived uplink code resource identifier; and
transmitter for transmitting a downlink transmission comprising the at least one downlink code sequence to the wireless subscriber communication unit.

Abstract
An apparatus, such as a base station, transmitting signaling information in a cellular communication system whereby a plurality of shared uplink transmission resources is divided into sets of mutually exclusive transmission resources. The apparatus comprises means for granting uplink resources to a wireless subscriber communication unit via a grant message for uplink transmission; means for receiving an uplink transmission from a wireless subscriber communication unit; means for deriving an uplink code resource identifier from the uplink transmission or the grant message; means for assigning at least one downlink code sequence used to carry downlink signaling information associated with the uplink transmission and which is derived using the uplink code resource identifier; and means for transmitting a downlink transmission comprising the at least one downlink code sequence to the wireless subscriber communication unit.

17. A computer-implemented method of transmitting signaling information in a cellular communication system supporting a plurality of shared uplink transmission resources being divided into sets of mutually exclusive transmission resources, the method comprising:
-
granting uplink resources to a wireless subscriber communication unit via a grant message; receiving an uplink transmission previously scheduled from a wireless subscriber communication unit, wherein the uplink transmission is previously scheduled by a base station; deriving an uplink code resource identifier from at least one of the uplink transmission or the uplink grant message; assigning at least one downlink code sequence used to carry downlink signaling information associated with the derived uplink code resource identifier; and transmitting a downlink transmission comprising the at least one downlink code sequence to the wireless subscriber communication unit. - View Dependent Claims (18)

19. A non-transitory computer readable medium encoded with executable instructions for transmitting signaling information in a cellular communication system supporting a plurality of shared uplink transmission resources being divided into sets of mutually exclusive transmission resources, the instructions comprising:
-
granting uplink resources to a wireless subscriber communication unit via a grant message; receiving an uplink transmission previously scheduled from a wireless subscriber communication unit, wherein the uplink transmission is previously scheduled by a base station; deriving an uplink code resource identifier from at least one of the uplink transmission or the uplink grant message; assigning at least one downlink code sequence used to carry downlink signaling information associate with the derived uplink code resource identifier; and transmitting a downlink transmission comprising the at least one downlink code sequence to the wireless subscriber communication unit. - View Dependent Claims (20)
