摘要:
A method and apparatus for taking measurements in a mobile telecommunications system are disclosed, the system comprising a network of a plurality of cells and at least one user equipment device. The method comprises, at the user equipment device, receiving a measurement control set-up command and, in response the user equipment device, setting up the measurements. Then it monitors for a change in state of the UE and, in response to a change in state, issuing a measurement control pause command and, in response, the user equipment device stopping taking measurements, and maintains the measurement settings initialised previously. The device then monitors for a change in state of the UE and, in response to a change in state, issuing a measurement control resume command and, in response, the user equipment device resumes taking measurements with the maintained measurement settings.

A method and apparatus are provided for selecting a transport format combination utilized in a mechanism of a wireless communication network for multiplexing data units between logical channels and transport channels. Upon receiving a configuration table comprising logical and transport channel information, a logical channel size restriction, a transport format combination set, and a transport format set, a transport format selection mechanism prioritizes each transport channel, sorts the transport formats according to priority and minimum buffer occupancy; wherein associated with each sorted transport format is a minimum and maximum buffer occupancy, and transport format combinations which use a transport format of a size equal to or less than the maximum buffer occupancy. The transport format selection mechanism upon the presence of data units having a logical channel size at a logical channel selects a transport format combination by comparing the logical channel size with the minimum and maximum buffer occupancy of each sorted transport format associated with a transport channel associated with the logical channel, wherein each sorted transport format has associated therewith at least one transport format combination identified as not exceeding logical channel size restrictions so that a transport format combination having at least one transport format of the most compatible size can be selected.

摘要:
A method for identifying supported transmission channel configurations in a mobile communications apparatus, the method comprising: calculating the required power value for each transmission channel configuration; and performing a sequential comparison of: an indication of an available measured power value, and an indication of the required power for each transmission channel configuration; and identifying a particular transmission channel configuration as supported if the required power for the particular transmission channel configuration is less than the available power value; wherein: the sequential comparison is performed in order of magnitude of value of the indication of the required power; and the method further comprising stopping said comparison when a supported transmission channel configuration is identified.
摘要:
A method and apparatus for selecting cells in a mobile telecommunications system, the system comprising a network of a plurality of cells of a Universal Mobile Telecommunications Systems (UMTS) and a network of a plurality of cells of a second Radio Access Technology (RAT), the method comprising, at a user equipment device: when in UMTS mode, flagging in a neighboring cell list stored on the user equipment device information for a cell of a second RAT which is known to be unsuitable for selection. Information from the neighboring cell list information for the flagged cell may be removed, in particular for a limited period of time.
摘要:
A method for cell reselection from a serving cell to another cell in a radio access network covering a geographical area divided into a plurality of cells, the method comprising: attempting to reselect to a first other cell with a higher rank value than the serving cell; setting up a channel on the first other cell and initiating a completion period; conditional on the completion period expiring before the first other cell is identified as being a suitable cell, receiving cell measurements for cells and creating a cell ranking list of the cells based on rank values of the cells; conditional on a second other cell having a higher rank value than the serving cell or first other cell, attempting to reselect to the second other cell.

摘要:
Mobile user equipment for use in a cellular communications environment performs an improved cell selection on transitions out of a connected mode state. The transitions might be from one connected mode state to another or from a connected mode state to idle mode. The improvement in cell selection lies in assembling the list of candidate cells prior to cell selection. In the prior art, the list of candidate cells would usually be restricted to the serving cell or active cells supporting communication between the equipment and the network prior to transition. In embodiments of the invention, the list might comprise cells which are not the serving cell or which are outside the active set, for example a network-preferred cell or cells neighbouring the serving cell or cells of the active set.
摘要:
A wireless communications device, and a method of operating a wireless communications device, the device operative to receive broadcast system information from a network, the device being arranged to: receive first broadcast system information, said first broadcast system information defining scheduling information for a plurality of items of further broadcast system information; define a subset containing a plurality of items of further broadcast system information; receive an item of further broadcast system information relating to whether transmit diversity is in use; when it is determined that the device has received further broadcast system information relating to whether transmit diversity is in use, wait until one of the following conditions has been met before implementing on the device any changes in transmit diversity as defined by the further broadcast system information relating to whether transmit diversity is in use: i) the device having received all members of the subset of further broadcast system information; or ii) the quality of a signal received by the device being determined to be below a threshold.
