Devices and methods of simultaneous data reception and measurement are generally described. A UE transmits to an eNB antenna capacity and receives a Beamformed Reference Signal (BRS) configuration in response. Beamformed signals from the eNB include a BRS subframe in accordance with the BRS configuration. The BRS subframe has a BRS whose structure depends on the UE antenna capacity. If the UE has a single antenna panels, neither an EPDCCH nor a PDSCH for the UE is in the BRS frame. If the UE has a single antenna panels and multiple ports or multiple antenna panels, the BRS may contain an EPDCCH or PDSCH for the UE as different ports or antenna panels may be assigned different functionality. The UE measures BRS Received Power (BRS-RP) of the BRS, transmits a BRS report based on the BRS-RP and selects an optimal beam based on BRS-RPs from BRSs of the beams.

The embodiments of the present document provide a method for processing dynamic channel detection, a station and an access point device. The method includes a station transmitting a dynamic channel detection request to an access point and the station deciding whether to use dynamic channel detection according to response information from the access point. The embodiments of the present document enable the station and the access point to negotiate whether to use a dynamic channel detection threshold. This is advantageous in finding the best balance point between improvement of channel utilization and avoidance of collision.

MIMO test systems and methods are provided that eliminate the need for a wired connection between the test system and the antenna ports of the DUT, thereby eliminating the need to open up the housing of the DUT and risk damaging or destroying it. The MIMO test systems and methods also eliminate the need for an anechoic chamber, thereby eliminating the cost and space requirements associated therewith. A suitable non-anechoic, electromagnetically-shielded chamber can be used in the test system that is much less expensive and that has a much smaller spatial footprint than a typical anechoic chamber used in MIMO test systems.

A communication device including one or more processors configured to perform a radio measurement to obtain a reception metric; identify a potential power reduction from a plurality of power reductions; scale the reception metric to compensate for the potential power reduction to obtain a reduced reception metric; and select a transmit power or a transmit repetition count for a radio frequency transceiver based on the reduced reception metric.

The present disclosure provides an access control method and apparatus, and a network device. The method includes: performing grid partitioning on a target cell covered by a wireless access point, to obtain multiple grids; grouping, based on a neighboring cell of the target cell, grids that satisfy a preset condition in the multiple grids into one or more interference clusters; calculating an access offset of each of the interference clusters; and sending, to a user in each interference cluster, an access offset of a corresponding interference cluster, so that the user selects a cell based on the access offset of the corresponding interference cluster. Grids of a target cell are grouped into interference clusters according to signal to interference plus noise ratios, and an access offset is set for each interference cluster, to ensure service quality and improve user experience.
