20170347371 · 2017-11-30 ·

A method of transmitting data between network devices over a non-deterministic network with a multiple channel access method, wherein it is not possible to determine, whether a network device can access the non-deterministic network, wherein the non-deterministic network comprises a plurality of network devices. The method includes the steps of: synchronising clocks of individual network devices of the plurality of network devices with each other, dividing time available for transmitting the data into timeslots, designating respective pairs of consecutive timeslots to the individual network devices of the plurality of network devices, wherein an individual network device transfers data only during the respective pairs of timeslots designated to it and evaluating, whether a network device of the plurality of network devices shall retransmit data, which it has already transmitted during a first timeslot of a pair timeslot, within the second timeslot of the pair of timeslots.

Cyclic prefix for non-contiguous signal transmission

Transmitted signals are modified to facilitate the emulation of circular convolution in non-contiguous transmission environments. These modified signals may be derived from well-known signature sequences. In an exemplary method, a tail portion of a final segment of a base signal is prefixed to an initial segment of the base signal, to form a first transmit segment. One or more additional transmit segments are formed by prefixing, to each of the one or more segments of the base signal other than the initial segment, a tail portion of the immediately preceding segment of the base signal. The transmit segments so formed are transmitted in respective ones of the plurality of non-contiguous transmit-time intervals. Corresponding methods for receiving the transmitted segments and reconstructing the base signal are also described, as are corresponding transmitting and receiving apparatuses.

Method for transporting Ethernet and non-Ethernet traffic over the same medium

Network elements within a network are configured to transport Ethernet traffic and non-Ethernet traffic over a same medium. The network elements can generate and process multi-frames that include the Ethernet traffic and non-Ethernet traffic. Each of the plurality of group slots includes a first set of bytes allocated to carry the non-Ethernet traffic and a second set of bytes allocated to carry the Ethernet traffic. At least one group slot of the plurality of group slots includes a timestamp, and the network elements are further configured to use the timestamp to reconstruct the original spacing between packets of the Ethernet traffic.

Techniques for controlling timing of downstream nodes in wireless communications

Aspects described herein relate to communicating timing advance (TA) values in an integrated access and backhaul (IAB) network. A first node in a wireless network can receive a media access control (MAC) control element (CE) indicating a downlink transmission timing advance for transmitting downlink communications. The first node can transmit downlink communications based on the MAC CE.
