摘要： Disclosed is a latency control method of a transmitter apparatus adapted for transmission of a plurality of packets under clear channel assessment requirements and latency requirements. The method comprises determining a maximum required time for clear channel assessment for the plurality of packets and determining a duration of time related to the determined maximum required time. For example, the duration of time may be determined as being equal to the determined maximum required time for clear channel assessment plus an offset. The offset may be equal to zero, or may be equal to a positive value. In some embodiments, the offset may be equal to, or larger than, a duration of another packet (which is not comprised in the plurality of packets). The method also comprises enforcing, for each packet of the plurality of packets, the determined duration of time to elapse after completion of transmission of the packet, before transmission of a subsequent packet of the plurality of packets is initiated. Corresponding latency control apparatus, transmitter apparatus, communication device and computer program product are also disclosed.

摘要： Embodiments include methods for decompression of headers of received Internet Protocol (IP) packets, such as by a device. Such methods include receiving a single transmission unit that includes a bitmap comprising a plurality of bits, and an aggregation of a first IP packet and a reference IP packet. Each bit in the bitmap indicates whether a corresponding header information element, of a header of the first IP packet, is redundant or non-redundant with respect to a corresponding header information element of a header of the reference IP packet. Such methods include reconstructing the header of the first IP packet based on the header of the reference IP packet and on the bitmap, and decompressing the header of the first IP packet. Other embodiments include devices configured to perform operations corresponding to such methods, and computer-readable media comprising computer-executable instructions that embody such methods.

摘要： An AP, a wireless device as well as a method performed by the AP and a method performed by the wireless device for communication between the AP and the wireless device are provided. The AP and wireless device are operable in a WLAN employing contention based access for radio resources. The method performed by the AP comprises obtaining (110) information about transmission pattern(s) of interfering radio system(s), and determining (130) a deviation of packet length for transmission(s) of the interfering radio systems(s). The method further comprises indicating (140), to the wireless device the deviation of packet length and the information about transmission pattern(s) of interfering radio system(s) when the deviation is less than a deviation threshold.

摘要： A network node, a wireless device and respective methods performed thereby for the network node to provide in formation to one or more wireless devices are provided. The network node and the wireless device are operable in a wireless communication network. The method performed by the network node comprises transmitting (120) a first message by means of broadcast indicating that a second message associated with the first message will be broadcasted after the transmission of the first message, the first message also indicating to the one or more wireless devices that feedback with regard to the second message is required should the second message not be received; and transmitting (130) the second message by means of broadcast.

摘要： A method for operating an access point providing access to a wireless network for a plurality of wireless devices, wherein the wireless network includes at least one transmission channel with a sequence of transmission slots. The method includes assigning a first transmission slot to a first wireless device for a scheduled transmission with a priority access to the first transmission slot for the first wireless device, detecting during the first transmission slot that the first wireless device is currently not transmitting data in the assigned first transmission slot, and transmitting an indication to at least a subset of the plurality of wireless devices indicating that at least a time range in the first transmission slot until an end of the first transmission slot is available to the plurality of wireless devices for a data transmission using a random access procedure.

摘要： In one example aspect, a method of transmitting packets wirelessly is provided. The method comprises, for each packet, requesting to transmit the packet, waiting for a respective random or pseudorandom time period before transmitting the packet, and transmitting the packet containing a respective data portion, wherein a position of the respective data portion in the packet is selected such that a time interval between transmission of respective data portions in adjacent packets is a constant time interval.
