Time-delayed message transmitting method in process control system, transmits messages extracted from primary message queue according to determined transmission window size, for time period less than delay time period

The size of window to be used for data transmission is determined based on combination of upper and lower end of window with respective sequence number of both primary and secondary queues in which messages and unconfirmed messages are stored respectively. A message is extracted from primary queue based on determined window size and transmitted along with verification request for time period less than transmission delay time. The unconfirmed messages are then extracted from the secondary queue, and verification information is then received. The message to be communicated is stored in primary queue. The preset amount of unconfirmed messages are stored in secondary queue based on transmission circulation time delay of the communication connection. The size of window to be used for data transmission is determined in preset manner so that difference between sequence number of the both the queues is in inverse relation with amount of message stored in secondary queues.

Wireless communication system and method

Incorporating count values into protocol data units to facilitate detection of lost PDU's

Data, such as a Radio Link Control (RLC) Service Data Unit (SDU) 30 in a Universal Mobile Telecommunication Services (UMTS) system, is transmitted between a transmitter and receiver in a sequence of two or more Protocol Data Units (PDU's) 32-36. A count value is incorporated into the headers of the PDU's, thereby generating a data structure with count values serving to indicate when one or more subsequent PDU's in the sequence can be expected at the receiver. The count value may relate to a countdown such that the presence in a PDU of a non-zero count value indicates that further PDU's are yet to follow in the current Transmission Time Interval (TTI). A value of "1" may alternatively be re-used (54,56 - fig.4) for all PDU's bar the last one (58), whose count value of "0" would indicate that this was the last PDU to be transmitted. A poll bit ("p", fig.4) may also accompany the count value. Enables a receiver to immediately detect lost RLC PDU's and quickly send NACK messages regarding the ...

Method of saving power by reducing reception time in a standby mode of a mobile communication terminal

A signal received by a mobile communication terminal in a standby mode is sampled, converted to digital, and stored. At least a part of the receive part is de-activated and the stored samples are processed. If it is decided that the samples contain insufficient data, the receive path may be re-activated to receive further samples. In this way, the various activities which the mobile needs to undertake while in the standby state (channel tracking, monitoring nearby base stations) are carried out with minimum drain on the power supply.

Narrow band ack / nack transmissions

The present disclosure provides various modifications to existing techniques for transmitting ACK and/or NACK in an narrow band communications system. For example, in a first aspect, an apparatus receives a downlink transmission and transmits a single tone ACK on an ACK channel using time-spreading. In another aspect, an apparatus determines whether an ACK has been received from a UE within a threshold amount of time, and when an ACK has not been received from the UE for at least the threshold amount of time, transmitting an indication to the UE to transmit regarding the ACK.

Data confirmation method and device

The embodiments of the present application relate to the field of communications, in particular to a data confirmation method and device in the field of communications. The method comprises: an STA sending a data frame; and the STA sending a confirmation request after an X duration starting when the data frame is done being sent, the X duration ≥ a delay in transmission by a backhaul link between APs, and the confirmation request being a confirmation request for the data frame. In embodiments of the present application, the STA sends a confirmation request after an X duration after the data frame is done being sent, the X duration ≥ a delay in transmission by a backhaul link between APs, thus completing the confirmation of AP side uplink joint reception on the premise of avoiding the waste of air-interface resources.

The transmitting entity either waits to receive the request from the receiving entity before resuming transmission of data or solicits the request from the receiving entity to resume transmission of data.

METHOD AND APPARATUS FOR TESTING A WIRELESS LINK USING CONFIGURABLE TRANSPORT CHANNELS AND RATES BY APPLYING MARKOV CHAIN MODELING VOICE FRAMES OF AN ARM APEECH ENCODER AND SID FRAMES

Techniques to test a wireless communication link using configurable channels and rates. A W-Markov test service may be invoked to test and/or verify the performance of the downlink and/or uplink using at least one transport channel for each link. Each transport channel may be individually configured. The W- Markov test service supports generation of test data based on a defined data sequence or a pseudo-random number generator. The testing may be performed based on a particular deterministic or pseudo-random activity model. For voice call testing, a first-order Markov model may be used to model voice activity and to select the rate to use for each transmission time interval (TTI). For Adaptive Multi-Rate (AMR), testing may be performed based on configurable AMR rates and silence descriptor (SID) types. The test data generation processes are synchronized between the transmitter and receiver. Bit, frame, and/or block error rates and other statistics may be collected.

SYSTEM FOR EFFICIENT RECOVERY OF NODE-B BUFFERED DATA FOLLOWING MAC LAYER RESET

A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC layer reset. UE generation of the status PDU is coupled with the MAC layer reset. The RNC generates a message with a MAC reset indication. Following the MAC layer reset all PDUs stored in the UE MAC layer reordering buffers are flushed to RLC entities and then processed by RLC entities prior to the generation of a PDU status report. The PDU status report provides to the RNC the status of all successfully received PDUs. Upon reception of a PDU status report in the RNC, missing PDUs are realized and retransmitted to the UE.

METHOD FOR RELEASING SINGLE TBFS IN A MOBILE RADIO SYSTEM

In mobile radio networks of second (GSM-GPRS) and third Generation (3G) a packet data service is provided. Packed data are transmitted on temporary connections named TBF set up in one or both the transmission directions independently. To open and maintain a TBF some dedicated resources shall be allocated by the network, for example: carrier, timeslots, codes (in case of CDMA), buffer memory for data queues. Mobiles shall forward to the network a request to open a TBF, while the release automatically follows the end of the active session, when the network acknowledges the uplink radio block marked as the last. Due to the bursty nature of packet services, it can very well happen that packet data are delivered by the application layer not continuously in time but with some delay in between, like the case which after sending the last assumed data packet, the uplink TBF will be released, and that some time later a new data packet is delivered for transmission by the same application. This requires ...

ENHANCED DATA LINK LAYER SELECTIVE REJECT MECHANISM IN NOISY WIRELESS ENVIRONMENT

A method of recovering lost frames transmitted between a packet data sending unit and a packet data receiving unit in a data communications system is disclosed. When a frame is successfully received by the packet data receiving unit (100), it identifies a failure to successfully receive prior frames (102), i.e., at least one frame prior to the frame successfully received at the packet data receiving unit. The packet data receiving unit starts a selective reject wait timer (106) and determines whether the number of frames missed so far is greater than or equal to a predetermined threshold (104). If the number of missed frames is greater than or equal to the preset limit, the packet data receiving unit generates a selective reject message that includes a payload indicating a first missed frame and subsequent missed frames (120). If the number of missed frames is less than the predetermined threshold, the packet data receiving unit waits until the expiration of the selective reject wait timer ...
