In one embodiment, a client device enters an area having an overhead mesh of access points, each access point comprising one or more directional transmitters each configured to transmit a beam cone in a substantially downward direction towards a floor of the area. The client device obtains an area-dependent communication schedule for the overhead mesh that is exclusive or partially-exclusive to the client device for the area. The client device sends, during an arbitrary timeslot of the area-dependent communication schedule, a pull request. The client device receives, from a particular access point in the overhead mesh, a packet in response to the pull request.

In a control apparatus, a relative value calculation unit calculates a first relative value of a second communication quality parameter value acquired by an acquisition unit relative to a first communication quality parameter value acquired by the acquisition unit. The first communication quality parameter value is a communication quality parameter value for an in-use channel, and the second communication quality parameter value is a communication quality parameter value for a standby channel. Further, a channel switching control unit determines whether or not a radio channel set as the standby channel should be switched from the standby channel to the in-use channel based on a comparison result obtained by comparing the first relative value calculated by the relative value calculation unit and a first threshold.

Embodiments of this application disclose a retransmission method and an apparatus in a multi-transmission reception point architecture, to improve HARQ retransmission performance in the multi-TRP architecture. The method includes: receiving first downlink control information from a network device on a first control resource; and receiving a first transmission version of downlink data from the network device based on the first downlink control information.
