    Abstract: A method for processing a received communication which includes periodic transmissions of a set of information segments. A first transmission of the set of information segments is received and processed to identify each of the segments as valid or invalid. The valid segments of the first set are then stored. Where all segments of the set are not stored, subsequent transmissions of the set of information segments are received and only those segments not previously stored are processed to identify each such segment as valid or invalid. The valid segments so identified are then stored. Subsequent transmissions are repeatedly received unless all segments of the set have been stored.

    Abstract: In one embodiment, a physical random access channel (PRACH) is used in communicating in a slotted wireless communication system. The slotted system uses repeating radio frame structure for communication. The PRACH is associated with a set of characteristics comprising: a set of channelization codes associated with the PRACH; at least one time slot associated with the PRACH; and a set of subchannels associated with the PRACH, the subchannels associated with a single time slot of the radio frames. In another embodiment, access service classes (ASCs) are separted in a wireless slotted communication system. Each ASC is associated with a unique set of channelization codes and subchannels of a physical random access channel (PRACH). The subchannels are associated with a single time slot of radio frames of the wireless slotted communication system.

    Abstract: Sub-channels are defined for a physical random access channel of a wireless time division duplex communication system using code division multiple access. The sub-channels carry information between system users and a system network. A series of radio frames have a sequence of timeslots. For a particular timeslot number of the sequence, each sub-channel of the particular timeslot number is uniquely defined by one radio frame of the series.

    Abstract: A method for characterizing base station processing and memory capabilities in a wireless communications system enables resource allocation to take these capabilities into account and to make allocations that avoid base station overload. A method for allocating resources in a wireless communication system including a base station and a radio network controller (RNC) begins by receiving an allocation request for a new service at the RNC. A set of resources is selected by the RNC to allocate to the new service, taking into account the capabilities of the base station. The allocation request is executed by the RNC if a set of resources can be found that does not exceed the capabilities of the base station.
