Methods are disclosed for communication devices capable of simultaneous transmission and reception, wherein a first method is for reception of a packet comprising a header and a payload and a second method is for transmission of a packet comprising a header and a payload. The second method comprises transmitting at least a part of the header. The first method comprises receiving at least a part of the header, attempting to decode the part of the header, and (when the part of the header is successfully decoded) transmitting a header acknowledgement signal. The second method comprises monitoring receipt of a header acknowledgement signal, and (when absence of the header acknowledgement signal is detected) interrupting the transmission of the packet and scheduling the packet for retransmission. Corresponding apparatuses, transceivers, communication devices and computer program products are also disclosed.

Acknowledgement for simultaneous transmission and reception

Methods, apparatus, and device-readable mediums are disclosed relating to wireless access in a network requiring a carrier-sense mechanism. One aspect provides a method performed by a transmitting device for transmitting to a receiving device in a wireless communications network. The transmitting device comprises a plurality of antenna elements. The method comprises: performing a directional carrier-sense assessment for one or more sub-bands configured for transmissions between the transmitting device and the receiving device, the directional carrier-sense assessment utilizing beamforming to detect a respective level of wireless activity on each of the sub-bands in a particular direction for transmissions to the receiving device; selecting a respective transmit power for each sub-band based on the determined level of wireless activity; and transmitting to the receiving device in the particular direction, using the respective selected transmit power for each sub-band.

Methods, apparatus and device-readable mediums are disclosed relating to wireless access in a network requiring a carrier-sense mechanism. One aspect provides a method performed by a transmitting device for transmitting to a receiving device in a 10 wireless communications network. The transmitting device comprises a plurality of antenna elements. The method comprises: performing a directional carrier-sense assessment for one or more sub-bands configured for transmissions between the transmitting device and the receiving device, the directional carrier-sense assessment utilizing beamforming to detect a respective level of wireless activity on each of the sub-15 bands in a particular direction for transmissions to the receiving device; selecting a respective transmit power for each sub-band based on the determined level of wireless activity; and transmitting to the receiving device in the particular direction, using the respective selected transmit power for each sub-band.
