Abstract: A scheme for resource allocation for variable rate users in a packet-based radio communication system such as a UMTS TDD system is based on a representation (200) of the resource space organized orthogonally in 3 dimensions by codes, timeslots and frames. The representation (200) is searched to identify new resources that may be allocated and updated when new resources have been allocated.

Abstract: A communication device that transmits data segments over an interface, wherein the communication device comprises transmission management logic. After receipt of a data segment for transmission over the interface, the transmission management logic determines a sequence number of a data segment to be transmitted and compares the sequence number of the data segment to be transmitted with at least one pending sequence number of a previous data segment. Based on the comparison, the transmission management logic either discards the data segment to be transmitted if the sequence number of the data segment matches the at least one pending sequence number of the previous data segment; or adds the sequence number of the data segment to the at least one pending sequence number and transmits the data segment if the sequence number of the data segment does not match the at least one pending sequence number.

Abstract: A wireless communications system is described which comprises a base station, a relay device, and a terminal device. The terminal device is operable to transmit a message to the base station via the relay device. The relay device is operable to add a relay header to the message received from the terminal device, the relay header comprising control information for controlling the transmission of subsequent messages from the terminal device to the relay device. The relay device is also operable to relay the message having the relay header added to the base station. By adding such control information to messages being relayed from the terminal device to the base station on the uplink, subsequent downlink communications from the base station to the terminal device can include the control information generated at the relay device (or transmission parameters derived from the control information).

The terminal device is operable to transmit a message to the base station via the relay device.

The relay device is also operable to relay the message having the relay header added to the base station. A problem with uplink-only relaying is that the relay device cannot feed back control information to the terminal device to support efficient future transmissions over the air interface between the terminal device and the relay device.

Abstract: An apparatus, method, and computer-readable medium encoded with executable instructions for Transmission Control Protocol (TCP) flow control in a communication system are provided. According to embodiments of the invention. TCP flow control includes determining delay in a transmit buffer of the system; and modifying TCP window size based on the determined delay and a target transmit buffer delay. An indication of a modified TCP window size is sent to a TCP server of the system in an acknowledge packet. Embodiments of the invention are particularly suitable for TCP flow control in wireless communication systems (e.g., UTRA) systems, and has the advantage that RTT (i.e., the latency of the system) can be substantially guaranteed, irrespective of the throughput that a user is allocated.

Abstract: A wireless communication system and method employing channel transport format allocation in a shared uplink channel between a UE and a Node B, and wherein the UE can determine a transport format combination which it can support, by: detecting in the UE a change in transport format combination that the UE can support; and sending to the Node B an indication of transport format combination that the UE can support, whereby efficiency of channel transport format allocation in the system may be improved. A conditional delay mechanism may be employed to reduce signalling overhead. This allows uplink shared channels to be efficiently used by providing a means by which UTRAN (UMTS terrestrial radio access network) is informed of the TFCs within the TFCS which can be used in the uplink by the UE.
