Abstract:
A method implemented in a first peer entity communicating with a second peer entity using a predetermined protocol includes receiving a first packet from the second peer entity. The method further includes identifying an instruction field included within the first packet, the instruction field indicating a predetermined function to be performed by the first peer entity. The method further includes determining whether the predetermined function can be performed by the first entity. The method also includes transmitting a second packet to the second peer entity indicating whether the first entity performs the predetermined function.
Abstract:
A method of transmitting data from a wireless network node over a MIMO channel to a wireless terminal may include transmitting first and second transport data blocks to the wireless terminal over the MIMO channel using a first time-frequency-resource-element (TFRE). Responsive to receiving a NACK message from the wireless terminal corresponding to the first and second transport data blocks transmitted using the first TFRE, the first and second transport data blocks may be retransmitted to the wireless terminal over the MIMO channel using a second TFRE.
Abstract:
Techniques for signaling radio link control (RLC) status reports to a wireless network, such as a network supporting multi-carrier High-Speed Downlink Packet Access (HSDPA). An example method performed in a mobile terminal comprises calculating a throughput estimate data transmissions to the mobile terminal, determining a rate at which to send radio link control status reports, based on the throughput estimate, and sending radio link control status reports to the wireless network node at the determined rate. In some embodiments, the mobile terminal determines the rate at which to send radio link control status reports by comparing the throughput estimate to a threshold value and selecting the rate based on the comparison. The threshold value may be received from the wireless network node prior to the comparison.
Abstract:
Some embodiments herein relate to a method in a radio network controller (14) for transmitting data to a user equipment (18) in a wireless communication system (10). The radio network controller (14) is communicating over a Radio Link Control layer with the user equipment (18). The radio network controller transmits a packet data unit to the user equipment (18). The packet data unit comprises a header with a first field, which first field comprises bits for a sequence number of the packet data unit. The header further comprises a second field comprising at least one bit indicating that a third field of the header comprises bits for the sequence number as an extension of bits to the first field for the sequence number.
Abstract:
An arrangement (17) is provided for setting and adjusting at least one parameter in a radio communication network (11), which is used in control of communication in the radio communication network and which is dependent on a round trip time for a signal travelling from a radio network controller (13) to a user equipment (16) and back to the radio network controller. The arrangement comprises a module (17a) for initially estimating a maximum value of the round trip time; a setting module (17b) for initially setting the parameter depending on the initially estimated maximum value of the round trip time; a module (17c) for measuring the round trip time; and a module (17d) for adjusting the parameter depending on the measured round trip time, wherein the measured round trip time is expected to be shorter than the initially estimated maximum value of the round trip time.

Abstract:
A channel quality of a radio channel between a transmitter and a receiver is detected by the receiver. The channel quality is compensated for an effect of a transmission on the radio channel when the receiver detected the channel quality or an effect of a future transmission on the radio channel. In a preferred example embodiment, the channel quality is compensated for both effects if present. The compensated channel quality is then used to determine one or more parameters for transmission from the transmitter to the receiver over the radio channel, e.g., an amount of data to be transmitted, a transmission power, and/or a transmission time period.
