Measurement handling with carrier aggregation

Measurement handling is of interest in a user equipment (ue) in connected mode, with the ue being configured with multiple downlink component carriers (ccs). The ue evaluates the signal quality of a specific cc of the configured ccs against a configurable threshold to determine the need for neighbor cell measurements. ... Optis Cellular Technology Llc

07/30/15 / #20150215885

Method of performing uplink synchronization in random access procedure

A method and device for performing a contention based random access procedure by a mobile communication terminal in communication with a base station. The method according to an embodiment includes transmitting a random access preamble message to the base station; receiving a random access response from the base station, the random access response including a timing advance command; determining a status of a mobile communication terminal time alignment timer; and ignoring the timing advance command if the mobile communication terminal time alignment timer is determined to be running in the determining step.. ...

07/23/15 / #20150208406

Method for scheduling distributed virtual resource blocks

In a wireless mobile communication system, user equipment receives downlink data and downlink control information including resource allocation information for the downlink data from a base station. Downlink data is mapped to physical resource blocks (prbs) based on the downlink control information. ... Optis Cellular Technology Llc

06/25/15 / #20150180638

Method for transmitting uplink signals

A method for transmitting uplink signals, which include ack/nack signals, control signals other than the ack/nack signals, and data signals, is disclosed. The method comprises serially multiplexing the control signals and the data signals; sequentially mapping the multiplexed signals within a specific resource region in accordance with a time-first mapping method, the specific resource region including a plurality of symbols and a plurality of virtual subcarriers; and arranging the ack/nack signals at both symbols near symbols to which a reference signal of the plurality of symbols is transmitted. ...

Ue wake-up ahead of paging occasions to retrieve paging configuration information when in (long) drx

In transmission of paging information from a mobile network to a terminal device (200), the terminal device applies a discontinuous reception cycle to enter a sleep mode. Further, the terminal device determines an advance wakeup time (aw) for leaving the sleep mode. ... Optis Cellular Technology Llc

06/04/15 / #20150156125

Method for managing a queue based on a change rate parameter

It is presented a queue manager arranged to manage a queue associated with a single radio access bearer of a mobile communication system. The queue manager comprises: a queue detector arranged to provide a change rate parameter indicating a rate of change of a size of the queue; a discard determiner arranged to determine a first discard condition based on the change rate parameter; and a packet discarder arranged to discard a packet in the queue when the first discard condition is satisfied. ... Optis Cellular Technology Llc

05/07/15 / #20150124679

Method for performing random access procedures and terminal thereof

A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a rach preamble. If the rach preamble was explicitly signaled by the network, a downlink channel is monitored until a new transmission is indicated according to radio resource allocation information received from the network. ... Optis Cellular Technology Llc

05/07/15 / #20150124666

Method for effectively transmitting control signal in wireless communication system

A method of performing harq performed by a user equipment (ue) is provided. The method includes receiving a bundling indicator which indicates the number of bundled downlink subframes, determining whether at least one bundled downlink subframe is missed by comparing the bundling indicator with the number of detected bundled downlink subframes, generating a representative ack/nack signal when no bundled downlink subframe is missed, and transmitting the representative ack/nack signal on an uplink channel. ...

Signaling support for antenna selection using subset lists and subset masks

A communication device is described herein that has control (or at least partial control) over which virtual antenna(s) in one or more base stations to use for transmissions. In one embodiment, the mobile phone performs the following steps: (1) receives an antenna subset list (from the scheduling unit) which identifies a configuration of virtual antennas that is associated with the base station(s); (2) uses the antenna subset list to select which virtual antenna(s) in the configuration of virtual antennas to use for transmissions; and (3) sends an antenna selection signal (to the scheduling unit) which contains information that instructs/requests the base station(s)/scheduling unit to use the selected virtual antenna(s) for transmissions.. ...
