20080207212 | METHOD, SYSTEM AND COMMUNICATION UNIT FOR REQUESTING A COMMUNICATION RESOURCE - A method for obtaining access to a physical uplink shared channel by a mobile station is provided. The method includes transmitting, by a mobile station, a physical uplink shared channel capacity request over the uplink dedicated channel to a base station. The method further includes receiving a physical uplink shared channel allocation. The physical uplink shared channel allocation is determined at a base station in response to the physical uplink shared channel capacity request. In some embodiments, the physical uplink shared channel allocation is received over a downlink common channel. The method may also further include accepting an assignment of the uplink dedicated channel. | 08-28-2008 |
20090201813 | METHOD AND ARRANGEMENT FOR TCP FLOW CONTROL - A communication entity is located at one end of a high latency communication link to support Transmission Control Protocol (TCP) communications between a first transceiver entity and a second transceiver entity. The communication entity comprises proxy logic arranged to inspect a received segment and, in response to identifying that the received segment does not contain data, the proxy logic transparently allows a plurality of synchronising segments to pass between the first transceiver entity and the second transceiver entity through the proxy logic such that the proxy logic generates locally at least one acknowledgement message based on the synchronising segments and the inspected received segment. | 08-13-2009 |

20110289234 | METHOD AND APPARATUS FOR MANAGING TRANSMISSION OF TCP DATA SEGMENTS - A communication device is arranged to transmit data segments over an interface, wherein the communication device comprises transmission management logic. In response to receipt of a data segment for transmission over the interface, the transmission management logic is arranged to determine a sequence number of a data segment to be transmitted and compare 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 to be transmitted matches the at least one pending sequence number of the previous data segment; or adds the sequence number of the data segment to be transmitted to the at least one pending sequence number and transmits the data segment over the interface if the sequence number of the data segment to be transmitted does not match the at least one pending sequence number. | 11-24-2011 |
20120278502 | METHOD AND APPARATUS FOR MANAGING TRANSMISSION OF TCP DATA SEGMENTS - 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. | 11-01-2012 |
20130044623 | WIRELESS COMMUNICATIONS SYSTEM AND METHOD - 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. 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. However, 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). | 02-21-2013 |

The method comprises determining an interference potential between the at least two wireless communication units when they are respectively communicating with the base station and scheduling a half duplex communication resource to the at least two wireless communication units based on the determined interference potential. | 10-31-2013 |
20140161024 | RELAY DEVICE AND METHOD - A wireless communications system including a base station, a relay device, and a terminal device. The terminal device can transmit one or more first type access request messages to request uplink resources from the base station, and if no response to the first type access request messages is received from the base station, transmit a second type access request message. The base station is responsive to a first type access request message received from the terminal device to transmit an allocation of uplink resources to the terminal device. The relay device is responsive to a second type access request message received from the terminal device to transmit a relayed access request message to request the base station to allocate uplink resources to the terminal device. The base station is responsive to the relayed access request message to transmit an allocation of uplink resources to the terminal device. | 06-12-2014 |
