摘要:
A transmitter that may have marginal power availability is enabled to autonomously retransmit previously transmitted frames containing the same data. The transmitter sends an initial frame to a base transceiver station (BTS) and immediately retransmits the same frame without regard to any ACK/NAK transmission from the BTS. The retransmissions are accumulated in the receiver and decoded after a sufficient quantity of the frame is transmitted. After receiving the last retransmitted frame the BTS sends an ACK/NAK to the transmitter that is accepted.

A method of aligning Transmission Time Intervals of physical channels in the uplink and downlink directions of a WCDMA communication system. The method comprises measuring or estimating the response processing delay at a user terminal, and delaying the Transmission Time Intervals of an uplink physical channel with respect to a corresponding downlink physical channel or channels by an amount dependent upon the measurement or estimate.

According to the invention data in a number of logical downlink intended for one or more mobile terminals are received in a first mapping unit, where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel and processes said data.

The present invention relates to a method and an arrangement for reducing a state transition time from a power saving state for a user equipment (18) in a communication network. The state transition time is reduced by retaining in the user equipment (18) one or more information parameter, such as the radio network temporary identifier for a high speed downlink shared channel (H-RNTI), when performing a state transition to said power saving state so as to enable a time reduction when said user equipment switches back from said power saving state.
摘要:
A method of optimising the use of radio resources in a mobile radio communication system during a combinational multimedia session involving circuit switched and packet switched sessions between user terminals, the method comprising: disabling an in-sequence delivery option of packets between radio network control nodes of the radio access network(s) serving the user terminals for said packet switched session.

Systems, devices, methods and software according to these exemplary embodiments provide for reducing the number of different sequence numbers used to transmit radio link control, RLC, data blocks to avoid, for example, sequence number stalling. This can be accomplished by, for example, transmitting or receiving RLC protocol data unit, PDU, segments as the initial or original instance of data communication.
摘要:
A radio base station suitable for performing a handover operation for a LTE-variant of a radio access network comprises a transceiver and a status report requester. The transceiver is configured to facilitate wireless transmission between the radio base station and a wireless terminal over an air interface, including transmission of a radio link bearer for the connection over a downlink from the radio base station to the wireless terminal. The status report requester is configured to determine, according to one or more pre-defined criteria, whether to request from the wireless terminal a status report for a radio bearer prior to the radio base station transferring user data for the connection to another radio base station in conjunction with a handover.

The invention relates to a technique for uplink data transmissions in, e.g., mobile networks. A method embodiment for performing the technique in a transmitter (122) comprises the steps of allocating, for a first transmission (T1′) as the transmission power for an uplink control channel (UCOCH), the smaller of an available transmission power and a desired transmission power for the uplink control channel; and allocating, for at least one subsequent transmission (T2′) triggered by a feedback indication (128), zero transmission power to the uplink control channel (UCOCH).
摘要:
Method and arrangement in a first node for requesting a status report from a second node. The first node and the second node are both comprised within a wireless communication network. The status report comprises positive and/or negative acknowledgement of data sent from the first node, to be received by the second node. The first node comprises a first counter configured to count the number of transmitted Protocol Data Units, PDUS, and a second counter configured to count the number of transmitted data bytes. The method and arrangements comprises initialising the first and the second counter to zero, transmitting data to be received by the second node, comparing the value of the first and the second counters with a first threshold limit value and a second threshold limit value and requesting a status report from the second node if any of the threshold limit values is reached or exceeded.
摘要:
A method of controlling the establishment of a packet switched bearer or bearers for carrying multimedia information between two or more user terminals during a circuit switched voice call, the method comprising at setup of or during the voice call, predicting at one of the user terminals the likelihood that multimedia information will be exchanged between the user terminals during the voice call based upon properties stored at that terminal for the or each other user or user terminal, and automatically establishing said bearer or not, based upon the prediction.
