HYBRID ARQ FOR A WIRELESS AD-HOC NETWORK AND A METHOD FOR USING THE SAME

A system and method for data transmission incorporating a hybrid automatic repeat request (ARQ) (124) function at each node in an ad-hoc network. Each node is configured to calculate an optimum segment size for transmission and thereafter executes the ARQ function to transmit and receive (124, 128) data segments with forward error correction and error detection coding. The coding allows the node to detect and locate errors within received segments and to provide an acknowledgement only after all segments are correctly received. A negative acknowledgement from the receiving node states the location of failed segments, and only failed segments are then retransmitted. The failed segments can be retransmitted in their original location and in other segment locations which contained segments that did not fail, thus reducing maximum time to successfully deliver the segments.

Method and device for http streaming over unreliable transport protocol

A method of transmission for data packets between a first device 100 and a second device 110 such as a client and server. Prior to packet transmission information is obtained regarding whether the packet is of a reliable or unreliable type. An association table containing packet identifiers and corresponding reliability information is included within the packet to be sent. On receiving a packet the second device 110 retrieves the association table and uses it to determine whether the packet was correctly received, its reliability type, and whether to request retransmission. If the first device 100 receives a request for retransmission then the packet is resent if the type is reliable; if the type is unreliable a notification is sent that the packet will not be retransmitted. The Transport Adaption layers 220/230 allow control over which parts of a HTTP message 140 are to be sent reliably or unreliably; for example, headers reliably and message body unreliably.

The method includes receiving one or more downlink assignments of a bundling window over a wireless downlink control channel; setting a reception status for each sub-frame of a downlink data channel in the bundling window based on whether the sub-frame on the downlink data channel was associated with a particular one of the received downlink assignments and based upon whether the sub-frame was successfully received; setting a reception status of sub-frames of the downlink data channel in the bundling window that did not have a corresponding downlink assignment to a predetermined value; and transmitting a response, the response based upon the reception statuses set by the response module.

WIRELESS PACKET COMMUNICATION METHOD

A plurality of data packets containing a sequence number are transmitted in parallel between two radio stations by using one radio channel and space division multiplex. Here, the radio station which has received a plurality of data packets transmitted in parallel by using the space division multiplex creates a single affirmative response containing information equivalent to the sequence number of the data packet received successfully and returns it to the radio station of the transmission side without using the space division multiplex. This increases the probability of the successful transmission of the affirmative response packet, thereby assuring improvement of the throughput by the parallel transmission.

METHOD FOR MINIMIZING FEEDBACK RESPONSES IN ARQ PROTOCOLS

The number of redundancy units transmitted (and/or requested) can be selected based on various criteria including, for example, estimated channel quality, estimated block quality, memory usage, a number of outstanding blocks, etc.

DATA TRANSMISSION APPARATUS AND METHOD

A data transmitter 10 transmits packets each with a sequence number and a priority added. A data receiver 20 detects any packet loss by referring to the sequence numbers added to the packets, and if detecting any packet of high priority as having been lost, requests for packet retransmission. Based on information about thus detected packet loss, the data receiver 20 generates and transmits an RR packet 110 indicating the packet reception state. The data transmitter 10 extracts from the RR packet 110 a packet loss ratio 200, and therewith, changes manners of priority assignment. The manners are so changed that the packet of high priority is found with a lower ratio when the packet loss ratio 200 is high, and when the packet loss ratio 200 is low, found with a higher ratio.

METHOD AND DEVICE FOR TRANSMITTING DIGITAL DATA IN THE FORM OF FRAME ORGANIZED MESSAGES

METHOD AND APPARATUS FOR MULTICASTING WITH FEEDBACK INFORMATION

A method for multicasting a packet begins by providing a buffer for each of two user equipments (UEs) in communication with a base station. A determi nation is made whether there is a previously unsent packet at the base stati on. A second determination is made whether both UE buffers are non-empty. A non-empty buffer is flushed if there is no previously unsent packet and if o ne of the buffers is non-empty. A packet is selected to be transmitted if th ere is a previously unsent packet or if both buffers are non-empty. The buff ers are updated based on feedback received from the UEs.

METHOD AND SYSTEM FOR AGGREGATING MESSAGES

Methods and systems are disclosed that support the aggregation of acknowledgement messages and control messages. Advantageously, acknowledgement and negative acknowledgement indications for multiple client nodes are combined into a single aggregated message which is broadcast or multicast to the multiple client nodes. Based on unique identifiers assigned to each client node, client nodes are grouped such that the aggregated acknowledgement messages can be efficiently encoded to conserve both network capacity when they are transmitted, as well as processing capacity when they are parsed by the client nodes. If code division multiple access (CDMA) technology is used, the aggregated acknowledgment message can be transmitted without CDMA spreading to effectively broadcast or multicast it to multiple client nodes. A similar technique can be employed for the efficient broadcast or multicast of aggregated control messages.

Techniques for supporting a wireless communication path from an antenna array having vertical components are discussed. Examples reduce training feedback for an increased number of communication paths by simply reporting on a subset of reference signals (RS) provided for various vertical beam configurations. Additional examples reduce feedback by virtual measurements based on differences between RS measurements. One such measurement may come from a full set of RSs for a reference beam configuration and the other measurement may come from a partial set of RSs for an additional beam configuration. This virtual measurement may also be based on a cross-correlation to the beamforming weights associated with the two configurations. Several examples of preparing and transmitting measurement reports consistent with the 3GPP LTE (Third Generation Partnership Project Long Term Evolution) standard are discussed. Support techniques also increase the diversity and reduce the power difference between the multiplexed layers into a space that transmits a common codeword.
