20140301223 | ESTIMATION OF DELAY PROBABILITY AND SKEW TIME OF DATA PACKET TRANSMITTED OVER A COMMUNICATION NETWORK - The present subject matter discloses systems and methods for data transfer in communication networks. In one implementation, the method comprises determining a skew time based in part on a maximum skew time of the communication network and a probability of a data packet being delayed during transmission over the communication network. The method further includes detecting at least one missing data packet transmission and initiating retransmission of the at least one missing data packet after a time interval exceeding the determined skew time. | 10-09-2014 |
20140321411 | SERVICE LINK ESTABLISHMENT - A method of establishing a plurality of service links between user equipment and a network access node in a wireless telecommunications network, and user equipment and a computer program product operable to perform that method. The method comprises: determining that there is data traffic to be sent between user equipment and the network access node; establishing a first service link for communication of the data traffic; determining that there is further data traffic requiring establishment of a second service link, to be sent between the user equipment and the network access node; determining a pre-set radio condition parameter indicative of radio condition required for successful communication of the further data traffic on the second service link between said user equipment and the network access node; assessing radio condition experienced at the user equipment and, if said radio condition parameter is being met, establishing a second service link for communication of the further data traffic. Such a method allows user equipment to determine whether a second service link is likely to be successfully established, thereby offering an opportunity to minimise unnecessary network signalling and the likelihood that a second service link will pull down the first service link | 10-30-2014 |
20140334440 | NETWORK ASSISTED INTERFERENCE CANCELLATION - The present application describes embodiments of methods for network assisted interference cancellation. Some embodiments of the method include broadcasting control information from a first cell over a common control channel. The control information is associated with a data channel transmitted by the first cell and the control information is usable by user equipment served by a second cell to mitigate interference caused by the data channel at the user equipment. | 11-13-2014 |
20140355573 | SHARING UP-LINK RESOURCES IN UNIVERSAL MOBILE TELECOMMUNICATIONS SYSTEM - The present subject matter discloses a method for sharing a enhanced uplink dedicated channel (E-DCH) resource from amongst a plurality of E-DCH resources on time multiplex basis. In one implementation, the method comprises receiving, from a user equipment (UE), a random access procedure (RAP) request for allocation of the common E-DCH resource from amongst a plurality of common E-DCH resources. The method further includes identifying the common E-DCH resource to be time multiplexed between a plurality of UEs based on the RAP request. The method also includes allocating the identified common E-DCH resource to the UE on a time multiplex basis, wherein the common E-DCH resource is shared among the plurality of UEs. | 12-04-2014 |
20140376475 | UPLINK TRANSMISSION - A method of controlling uplink transmission on an acquired common channel by user equipment in a wireless communications network. User equipment and a computer program product operable to perform that method. The method comprises: determining a predetermined acquired common channel retention period; requesting allocation of common network resource for an uplink transmission; receiving an indication of an allocated acquired common channel; assessing whether said uplink transmission meets uplink criteria for said allocated acquired common channel and, if said uplink criteria are met, transmitting said uplink transmission on said allocated acquired common channel within said common channel retention period. Aspects allow common channels in a network to be used by user equipment if it is determined that a pending uplink transmission is suitable for transmission on an allocated common channel. | 12-25-2014 |
20150043341 | METHOD AND APPARATUS FOR RESOURCE ALLOCATION IN A MIMO COMMUNICATION SYSTEM - A method of controlling uplink multiple input multiple output transmission between user equipment and a base station of a wireless communications network, user equipment and a computer program product are disclosed. The method comprises the steps of: identifying whether insufficient capacity exists on a primary uplink stream to carry pending uplink data packets; and if insufficient capacity exists, preventing establishment of a secondary uplink stream when it is determined that pending uplink data packets which would not be carried by the primary uplink stream would under-utilise the secondary uplink stream. In this way, the disproportionate interference and consumption of resources that would otherwise result from the establishment of a secondary stream in order to carry relatively little data is avoided which reduces the resources utilized, increases power efficiency and minimizes interference. | 02-12-2015 |
20150063239 | MULTIPLE-INPUT-MULTIPLE-OUTPUT (MIMO) COMMUNICATION - A method for supporting multiple-input-multiple-output communications with a base station of a wireless telecommunications network, user equipment and a computer program product are disclosed. The method comprises the steps of establishing a grant associated with a secondary stream; and determining a transport block size for said secondary stream in accordance with a relationship between grant and transport block size, said relationship differing from a primary relationship between grant and transport block size used to determine a primary transport block size for a primary stream. By using this approach, where a different relationship, mapping, function or lookup table is used to derive the transport block size for the secondary stream to that relationship, mapping or function used to derive the transport block size for the primary stream from the grant of the primary stream enables different transport block sizes to be used, each of which may be appropriate to its associated stream. | 03-05-2015 |
20150146811 | MULTIPLE-INPUT-MULTIPLE-OUTPUT (MIMO) COMMUNICATION - A method for supporting multiple-input-multiple-output communications, user equipment and a computer program product are disclosed. The method comprises the steps of: determining whether an amount of data available for transmission that is greater than a maximum capacity of one the plurality of streams is below an associated threshold amount of at least another of the plurality of streams; and if so, preventing transmission of at least one of the plurality of streams. This helps to ensure that a stream is only used for transmission when the residual data is sufficient to warrant its use. This prevents, for example, inefficient use of a stream which may otherwise result in excessive transmission power, high usage of code resource and additional inter-stream interference. | 05-28-2015 |
