Abstract: 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.

Abstract: 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.

Abstract: A method and an access node of a wireless network, for controlling uplink transmissions from wireless devices. It is detected that both a Narrow Band wireless device capable of receiving signals on a first narrow bandwidth channel and one or more legacy wireless devices capable of receiving signals on a second broad bandwidth channel are present. The second broad channel covers the first narrow channel. When receiving an uplink transmission from the Narrow Band device that indicates pending uplink data, the access node performs a downlink transmission that both Narrow Band wireless devices and legacy wireless devices can receive and decode. The downlink transmission indicates that the Narrow Band wireless device is allowed to transmit its pending uplink data on allocated resources within the first bandwidth channel, and that the second bandwidth channel is occupied.
