Abstract: The downlink channelization code limitation problem encountered in spread spectrum or CDMA cellular systems is resolved by using codes from a different, non-orthogonal code set when operating in the slotted mode. The non-orthogonal code sets can be constructed by using the same channelization code tree, but applying a different scrambling code.

Abstract: A dual mode mobile terminal ( 30 ) is capable of communicating (e.g., with a core network) either via a first radio access network ( 12 ) having a first type radio access technology (GSM) or a second radio access network ( 14 ) having a second type radio access technology (UTRAN). When conditions warrant, a network node prepares a radio access technology (RAT) handover message for transmission to the equipment unit (UE) in conjunction with handover of the mobile terminal (MT) from the first radio access network to the second radio access network, and an associated change of operation mode of the mobile terminal (MT) from the first mode to the second mode. In accordance with the present invention, a radio access technology handover message includes a first information element representative of a first parameter from which a value of a second parameter can be derived so that the second parameter need not be included as a separate information element in the radio access technology handover message. Not including the second parameter as a separate element in the radio access technology handover message facilitates non-segmentation of the radio access technology handover message. In one aspect of the invention, the radio access technology handover message is a RRC Handover to UTRAN message; the first parameter is a Serving-Radio Network Temporary Identifier (S-RNTI 2); and, the second parameter is an information element which facilitates distribution of load and transmission of traffic in the radio access network (e.g., a Default DPCH Offset Value).

Abstract: Variable rate data transmissions are accommodated having BRI transmitted in the same frame as the data itself. When Walsh code spreading is employed, the despreading process can be split into two separate despreading operations, with buffering between the two operations. Buffering is made of the intermediate symbols between the despreading stages, and can be made at the maximum user data rate instead of the much higher chip rate. In this way, the size of the buffer in the receiver can be significantly reduced.

Abstract: A Calculated Transport Format Combination (CTFC) provides efficient signalling of transport format combinations to be assigned TFCI values. A sequence of CTFCs is signalled from higher layers (30) to Node B (22) and the user equipment (UE) (20), where each CTFC in order is allocated a TFCI value. From the CTFC both Node B and the user equipment (UE) can determine the exact transport format combinations the TFCI values (used to communicate between Node B and UE) represent. The sequence of CTFC values includes only CTFC values for valid combinations of transport formats.

Abstract: An uplink common physical channel (random access channel) frame structure with a separate preamble and data portion. The preamble is used by a base station to detect that a mobile station is attempting a random access request. The data portion of the channel includes user data, and pilot symbols that provide energy for channel estimation during reception of the data portion. A guard interval is preferably inserted between the preamble and data portion of the frame, which enables data detection to occur during an idle period. As such, the frame structures for both the common physical (random access) uplink channel and dedicated physical (traffic) uplink channel are compatible.
