  • Patent number: 11871341
    Abstract: A cellular communication system is disclosed in which a base station operates a cell which has a supplementary uplink portion (e.g. on a different frequency and/or using a different technology). The base station broadcasts an offset for user equipment (UE) in its coverage area to assist the UE performing cell selection. Specifically, the UE determines, based on measurements for the cell, the offset, and capability of the UE to communicate using the supplementary uplink portion, whether the cell of the base station is an appropriate candidate for cell selection such that: if the UE is capable of communicating using the supplementary uplink portion then the UE performs cell (re)selection based on the offset; and if the UE is not capable of communicating using the supplementary uplink portion then the UE disregards the offset in its cell (re)selection.

  • Patent number: 11832126
    Abstract: A non-AP STA of a multi-link device (STA MLD) may be configured to encode a multi-link (ML) probe request frame for transmission to an access point STA (AP) of an AP MLD comprising a plurality of affiliated APs. When the probe request frame is sent outside the context of active scanning, to discover an AP of the AP MLD the ML probe request frame may be encoded to have an Address 1 field set to a broadcast address and an Address 3 field set to a BSSID of the AP, or encoded to have the Address 1 field set to a basic service set identity (BSSID) of the AP's BS. The non-AP STA may refrain from transmitting the ML probe request frame to the AP of the AP MLD in a corresponding link when another non-AP STA of the AP MLD has already received a ML probe response that included complete information from any one of the APs of the AP MLD in any link.
