Abstract: This disclosure provides methods, devices and systems for sharing resources of a wireless medium. Particular implementations relate more specifically to coordinated AP (CAP) time-division-multiple-access (TDMA) and orthogonal-frequency-division-multiple access (OFDMA) techniques for sharing the time or frequency resources of a transmission opportunity (TXOP). According to such techniques, an AP that wins contention and gains access to the wireless medium for the duration of a TXOP may share its time or frequency resources with other selected APs. To share its resources, the winning AP may partition the TXOP into multiple time or frequency segments each including respective time or frequency resources representing a portion of the TXOP, and allocate each of the time or frequency segments to itself or to one of the selected APs.

Abstract: The invention relates to a client device (100) and a network access node (300) for transmitting and receiving a random access preamble. The modulation sequence for the random access preamble is based on a first sequence and a second sequence. The first sequence is a sequence from a set of near-orthogonal sequences and the second sequence is a sequence from a set of constant envelope sequences. Due to its construction, the random access preamble herein provides low PAPR and suppresses the side-lobes in its auto-correlation function while producing a set of preambles with low cross-correlation. Furthermore, the invention also relates to corresponding methods and a computer program.

Abstract: Hybrid use of dual policies is provided to improve a communication system. In a multiple access scenario, when an inactive user equipment (UE) transitions to an active state, it may be become a burden to a radio cell on which it was previously camping. In some embodiments, hybrid load balancing is provided using a hierarchical machine learning paradigm based on reinforcement learning in which an LSTM generates a goal for one policy influencing cell reselection so that another policy influencing handover over active UEs can be assisted. The communication system as influenced by the policies is modeled as a Markov decision process (MDP). The policies controlling the active UEs and inactive UEs are coupled, and measureable system characteristics are improved. In some embodiments, policy actions depend at least in part on energy saving.

Abstract: Supporting multi-signal source communications in a distributed communications system (DCS) is disclosed. The DCS includes a routing circuit configured to route downlink and uplink communications signals between multiple signal sources and a number of remote units. In examples disclosed herein, the routing circuit and each of the remote units are functionally divided based on an open radio access network (O-RAN) Split 7.2 configuration. To support downlink communications from multiple signal sources, the routing circuit generates a downlink frequency-domain communications signal, which includes one or more selected logical channels associated with one or more of the multiple signal sources, for each of the remote units in the DCS. Accordingly, each remote unit converts the downlink frequency-domain communications signal into a downlink time-domain communications signal for transmission in a downlink radio frequency (RF) communications signal.
