摘要:
A method, an apparatus and a communication system for collision detection for a random access procedure for an uplink data channel. In one embodiment, the apparatus includes a module configured to transmit a data transmission on the uplink data channel, and an uplink scheduling and signal generating module configured to select random access parameters for a random access procedure and schedule the data transmission using the random access parameters for the random access procedure. The uplink scheduling and signal generating module is also configured to interrupt the data transmission after a predetermined time interval if the apparatus does not receive a permission signal from a network element during the predetermined time interval.

The invention describes user equipment for communicating data in a communications system comprising a set of user equipment; comprising a transceiver arranged to receive a first data packet over a communications data channel and an associated second data packet over a communications control channel. The second data packet comprises a first identifier arranged to identify a subset of the set of user equipment and the first data packet comprises a second identifier arranged to identify at least one of the subset of user equipment. The user equipment further comprising a processor arranged to determine from the second data packet first identifier if the said user equipment is one of the said subset of user equipment and from the second identifier if the said user equipment is said the at least one of the subset of user equipment. Wherein the processor is further arranged to decode the first data packet if the processor determines the said user equipment is one of the said subset of user equipment and is the said at least one of the subset of user equipment.

Disclosed are a user equipment and a communications node for communicating data in a communications system including a plurality of user equipments, as well as a method for communicating the data by a user equipment and a method for communicating data by a communications node, wherein data are transmitted from the communications node via a downlink shared channel and received by the user equipment. The user equipment comprises an acknowledger which provides uplink acknowledgements with respect to downlink shared channel transmission for user equipments without a dedicated connection which acknowledgements are received by an acknowledgement receiver included in the communications node. The uplink acknowledgements are transferred through a common uplink feedback channel.

摘要:
A method and equipment by which a radio access network of a wireless network communicates to a user equipment wireless communication device an indication that the user equipment is to flush one or more send buffers. A flag is included in a message to indicate that the one or more send buffers are to be flushed. The message is for example a message indicating reconfiguration is to be performed, and the flag (if set) is to be interpreted by the user equipment as indicating that the one or more send buffers are to be flushed prior to performing the reconfiguration. A corresponding method and equipment for a user equipment wireless communication device are also provided.

The definition and use of an additional timer for the MAC-hs reordering function in a user equipment. The timer counts transmission time intervals and is reset each time that the user equipment receives a data packet. If the timer reaches a set value, indicating a sufficiently long period of inactivity, then the transmission sequence number is reset to zero or another predefined value. A base station can run a similar timer and, after the timer reaches a set value, can consider the user equipment as no longer being active.

A radio resource control in an HSUPA system is provided. The control procedure includes: communicating data blocks between user equipment and a network infrastructure over a physical High Speed Uplink Packet Access channel; communicating block acknowledgement messages between the user equipment and the network infrastructure, each block acknowledgement message indicating whether or not a data block was received successfully; and controlling transmission power of the physical HSUPA channel on the basis of at least one block acknowledgement message.
