Techniques are disclosed that dynamically allocate communications resources in a wireless communications network, such as a wireless personal area network (WPAN). For instance, a wireless communications device may obtain a resource allocation. This resource allocation includes a time slot (e.g., a TDMA time slot) within a wireless communications medium. The device determines a first portion of the time slot in which it intends to transmit data. Also, the wireless communications device relinquishes a second portion of the time slot that occurs after the first portion of the time slot. Based on this relinquishment, a central controller device may reallocate the second portion of the time slot.

A radio communication system 1 according to an embodiment comprises: a pico cell base station PeNB provided in a communication area of a macro cell base station MeNB and having transmission power lower than transmission power of the macro cell base station MeNB. A resource division ratio is determined with respect to radio resources to be usable as a physical downlink shared channel (PDSCH), indicating a ratio of macro cell unusable PDSCH resources and macro cell usable PDSCH resources. The radio resources are assigned to a radio terminal connected to the macro cell base station MeNB, out of the macro cell usable PDSCH resources determined according to the determined resource division ratio. The resource division ratio is determined according to expected throughputs of each of cell edge terminals of the macro cell base station MeNB and the pico cell base station PeNB.

A Multi-Access Edge Computing (MEC) device, associated with a base station, may include a processor configured to receive a request to send data to a plurality of user equipment (UE) devices. The MEC device may be further configured to determine that the data is to be delivered to the plurality of UE devices by the base station via multicast; determine signal quality values for the plurality of UE devices; select a subset of the plurality of UE devices based on the determined signal quality values; and send, using the base station, the data to the selected subset of the plurality of UE devices via multicast, and delaying or terminating delivery of the requested data to UE devices, of the plurality of UE devices, that are not in the selected subset.

A Wi-Fi controller identifies a mismatch between a first prefix of a first IPv6 address for a data packet corresponding to a first VLAN on which the data packet was sent from the station to the access point, and a prefix of a second IPv6 address for a second VLAN from which the data packet was transmitted from the access point to the Wi-Fi controller. Responsive to the VLAN mismatch identification, the Wi-Fi controller transmits a DHCP reconfiguration packet to the station using the first VLAN. The DHCP reconfiguration packet causes the station to transmit a rebind packet to the DHCP server. The rebind packet causes the DHCP server to transmit an ACK frame on the first VLAN setting the valid lifetime for the first IPv6 address to zero.

A method for opening radio pipeline capability and a collaborative controller are disclosed. In an embodiment the method includes receiving, by an access network collaborative controller, a request message from a capability opening gateway, wherein the request message carries a service requirement of a first user equipment UE, and controlling, by the collaborative controller, a first radio pipeline device according to the request message so that a radio pipeline resource allocated to the first UE meets the service requirement.

An Integrated Access and Backhaul (JAB) node incorporates two functions, a so-called “base station” function and a so-called “mobile terminal” function. In order to limit the interferences between base stations, all IAB nodes in the same network must be synchronised with one another. In order to ensure this synchronisation, each IAB node may use a time shift value transmitted by its parent node. However, since an IAB architecture is an arborescent architecture, errors in measuring an estimated time shift value for a given IAB node have repercussions on the measurements of estimated time shift values for its child node and so on. Accordingly, the “base station” function of a child IAB node is not activated as long as a time shift value determined by its parent node does not meet a synchronisation criterion.
