Apparatus and method for communicating signaling information

摘要

A wireless subscriber communication unit is provided for operation in a cellular communication system having a plurality of shared uplink and downlink transmission resources, each divided into sets of mutually exclusive resources. The shared uplink transmission resources are defined in terms of codes and timeslots. The communication unit comprises a receiver, control, and transmitter unit. The receiver unit receives scheduling information including an assignment of a scheduled uplink transmission resource from the shared uplink transmission resources from a network infrastructure apparatus. The control unit derives an uplink resource identifier related to the scheduled uplink transmission resource from the received scheduling information. The transmitter unit transmits an uplink transmission, which includes the uplink resource identifier, using the scheduled uplink transmission resource. The control unit receives a downlink transmission associated with the uplink transmission on a downlink transmission resource determined from at least one of the received scheduled uplink resource or identifier.

1. A wireless subscriber communication unit for operation in a cellular communication system having a plurality of shared uplink transmission resources divided into sets of mutually exclusive uplink transmission resources, and a plurality of shared downlink transmission resources divided into sets of mutually exclusive downlink transmission resources, wherein the shared uplink transmission resources are defined in terms of codes and timeslots; the wireless subscriber communication unit comprising:
a transceiver configured to receive scheduling information including an assignment of a scheduled uplink transmission resource from said plurality of shared uplink transmission resources from a network infrastructure apparatus; and a controller configured to derive an uplink resource identifier related to said scheduled uplink transmission resource from said received scheduling information; and wherein:
the transceiver is also configured to transmit an uplink transmission using the scheduled uplink transmission resource, the uplink transmission including the uplink resource identifier;the controller is:
configured to receive a downlink transmission associated with said uplink transmission on a downlink transmission resource determined from at least one of said received scheduled uplink resource or said uplink resource identifier; andarranged to associate the downlink transmission resource with an acknowledgement signal and with an uplink transmission using the uplink resource identifier, the acknowledgement signal being carried by an Enhanced Uplink Hybrid ARO Indicator Channel (E-HICH) for a set of users, and a downlink code sequence associated with the derived uplink resource identifier being dynamically assigned and re-assigned in a single transmit time interval (TTI), wherein the acknowledgment signal is code-division-multiplexed (CDM).
