摘要:
New methods and devices for implementing an ARQ mechanism over a multi-hop connection (sender-relay-receiver) are proposed. A communication protocol is described in accordance with which data units are arranged in a sequence and each sent data unit is identifiable by a sequence position identifier. The sender implements a sending peer, the relay a relay peer and the receiver a receiving peer. Feedback messages are exchanged, which using said sequence position identifiers, carry information on a receipt of sent data units. The communication protocol provides for at least a first type and a second type of receipt information, the first type (RACK) of receipt information being indicative of a correct receipt of a data unit at a relay peer of said communication protocol, and the second type (ACK) of receipt information being indicative of a correct receipt of a data unit at a final destination peer of said communication protocol.

A method of enabling a user equipment to perform a contention based random access, includes maintaining a set of non-dedicated random access preambles for contention-free random access and a set dedicated random access preambles for contention-based random access. The method also includes determining a random access preamble identifier and transmitting a message to the user equipment containing the determined random access preamble identifier. Additionally, the method includes receiving from the user equipment a non-dedicated random access preamble that is selected by the user equipment based on the random access preamble identifier comprised in the transmitted message.

A vessel bifurcation wire assist device and related methods of advancing guidewires into main and branch vessels of a vessel bifurcation. The wire assist device includes a first guidewire housing member defining a first guidewire lumen sized to advance over a first guidewire, and a second guidewire housing member defining a second guidewire lumen sized to advance over a second guidewire. The second guidewire housing member has a first directional arrangement and a second directional arrangement. The first directional arrangement provides a parallel arrangement of the second guidewire relative to the first guidewire housing member, and the second directional arrangement provides an angled arrangement of the second guidewire relative to the first guidewire housing member.

A method for producing fresh milk having a longer shelf life. The method steps include: providing raw milk; and performing an at least two-step centrifugal germ removal process of the raw milk before a standardization process of the raw milk is carried out. A method may also include performing a first step of a two-step centrifugal germ removal process before a skimming process separating skimmed milk is carried out and performing a second step of the two-step centrifugal germ removal process during the carrying out of the skimming process separating skimmed milk.

A technique of configuring link layer entities for a handover is described. In a method embodiment, the technique includes receiving from a recipient of protocol data units a supplemental status report for an existing ARQ connection in context with an imminent handover, determining service data units corresponding to buffered protocol data units taking into account information included in the supplemental report, and transferring the determined service data units to a link layer entity which is to establish a new ARQ connection to the recipient. The forced status synchronization that is based on the supplemental report prevents the transfer of service data units that have already been successfully received at the recipient.
摘要:
A technique is provided for processing data in a packet-based communications environment. A single data packet is encapsulated into a single link layer packet data unit. The link layer unit is encoded to form at least one code block. After the currently available radio resource capacity during a fixed duration transmission interval has been determined, bits within the code block are selected to fit into or otherwise match the radio resource capacity. Thereafter, the selected bits are transmitted via a physical layer. In some variations, unsolicited redundant sets of bits are transmitted thereafter to facilitate successful receipt.

A system and method for transporting data units for a communication network. In a communication between two peers a proxy and a network entity for controlling a partial communication are provided. One or both of the proxy and the network entity is arranged to modify one or more of the data units, in order to provide communication control related information that is different from communication control related information exchanged between the two peers The respective other or both of the proxy and the network entity is arranged to perform data unit transmission control based on the different communication control related information.

A method of controlling access in a telecommunication network in which a communication medium, such as a set of frequencies, time slots, or codes, is shared among a plurality of mobile units. Transmissions from the mobile units utilize different access modes, such as a direct access mode and a scheduled access mode. Additionally, the transmissions are divided into different communication types, each having an associated priority. A mode access control unit determines for each priority, which access mode to utilize for the associated communication type. Mobile units having data to transmit access the shared communication medium utilizing the access mode determined for the priority of the communication type to which the data belongs.
摘要:
An x-ray system is provided. The x-ray system includes an x-ray emitter which can be adjusted by at least one arm as a first x-ray component and a recording system which can be adjusted independently of the at least one arm. The recording system may be adjusted by at least one additional arm as the further x-ray component. The two arms can be pivotably mounted about a common axis of rotation.

A marker for a faucet is provided to indicate information about the liquid or other flowable product to be dispensed from the faucet. The faucet, itself, includes a body and a handle operatively connected to the body for controlling flow of liquid through the body. The handle includes a base, first and second legs that project outwardly from the base, and a cross-bar that interconnects the legs at a location spaced from the base. The first and second legs and the cross-bar at least partially define an opening. The marker includes a body that is removably secured in the opening of the handle. The body of the marker includes indicia that provides information to a user of the faucet. The body is a resilient polymeric structure. Alternatively, the marker includes a handle engagement hook and a display region that includes indicia. The engagement hook is adapted to be engaged with the cross-bar of the faucet handle.
