An approach for performing a random access procedure using soft-dedicated preambles is disclosed. A module designates one of a plurality of preambles, associated with one or more random access channels, as a soft-dedicated preamble. The soft-dedicated preamble is used by a user equipment that is either contention-based or non-contention-based.

There is provided a method, an apparatus and a computer program product, wherein the method includes applying at least one procedure for inter-frequency measurements of at least one carrier, wherein a first procedure is applied when a carrier having at least one cell deployed for providing non-continuous coverage radio access is to be measured and a second procedure is applied when a carrier having at least one cell deployed for providing continuous coverage radio access is to be measured, and performing the inter-frequency measurements according to the applied procedure, when the procedure for the inter-frequency measurements is on.

The invention relates to an arrangement and method for transporting test tubes (1) automatically between different processing stages and equipment in laboratories. In the method, the test tubes (1) are placed on transport bases (3) for transportation within the system and the identification data of the test tube (1) is read to identify the sample, after which the transport bases (3) can be moved within the transportation system with the aid of conveyors (15-18)to operation stations, for operations to be carried out on the test tube (1) or sample. The data.required to move the transport base within the system are recorded in a memory circuit forming part of the transport base (3) on the basis of the identification data of the sample, which can be read without physical contact by a recording device (4), while the transport base (3) is handled at a control station (25), which is formed by at least one processing point together with the track (28) and which control station includes at least a handling device (36), in which there is a grip (38) which grips the transport base (3) and transfers the base (3) in a direction transverse to the direction of movement of the conveyor track, to take the transport base (3) to the processing point following the first processing point, and devices (37) which prevent the next transport base (3) from entering the control station (25) during the transfer, the data in the recording devices of the transport base (3) being read at the control station during handling.
摘要:
A method is provided for transmitting a message comprising one or more preambles and a message body from a user equipment device to a network entity. The method includes determining whether it is allowed to transmit a first preamble of the message to the network entity in an immediately available time slot of a random access channel, transmitting the first preamble if it is allowed, and transmitting the message body if a positive acknowledgement to the preamble is received from the network entity on another channel. The user equipment device may determine transmitting the preamble invariably, based on a persistence value or an indication received from the network entity, based on whether the device has not transmitted on the random access channel for longer than a predetermined, or based on whether the device has not transmitted on the random access channel for longer than a random time period.
摘要:
A random access procedure for use by a UE wireless communication terminal in communicating with a base station (or Node-B or eNB) of a radio access network, and in particular a E-UTRA network. A random access preamble is sent by the UE via RACH separate and prior to a random access message burst, which is sent on SCH but not until the UE receives one or more messages indicating an acknowledgment of the preamble and providing an allocation on SCH for use in transmitting the message burst, and also providing a preamble identifier, which the radio access network can then use to request retransmission of the message burst if necessary.
摘要:
A pilot structure, a method, and a receiver for multi-carrier cellular communications defining a specific Time Division Multiplexer/Multiplexing pilot pattern and pilot sequence for a sub-frame with short system information. A primary synchronization sequence is configured to be transmitted every predetermine number of sub-frames in a defined bandwidth. A primary common pilot is configured to be transmitted for each sub-frame. Short system information is configured to be transmitted once per frame to define the pilot structure of sub-frames in a frame period to define a structure of a frame period.
摘要:
The invention relates to a test tube carrier (4) for transporting test tubes in a transport system, said carrier (4) comprising a base (8) having a recess made thereto for accommodating the bottom of a test tube/vial (1), and support members (9, 10) adapted to the carrier base (8) for clamping a test tube (1) inserted in said recess and supporting the same. The support members (9, 10) are permanently affixed to said carrier base (8) and comprise elongated portions with their free ends bent toward the vertical center axis of the carrier base and said upper ends providing a support surface (22) for making supportive contact to the test tube. The bottom of the carrier base recess for accommodating a test tube is advantageously made flat and the carrier base is provided with test tube support members whose support surfaces (22) extend to at least two different heights from the top level of the carrier base (8).
