  • Publication number: 20240357688
    Abstract: A method for performing operation mode transition control in a wireless communication system and associated apparatus are provided, where a non-access-point multi-link device (non-AP MLD) is wirelessly linking to a first access point multi-link device (AP MLD). The method includes: transmitting, by the non-AP MLD, a first operation mode notification in a first management frame to the first AP MLD, for a first target operation mode to which the non-AP MLD is going to transit, carrying at least information regarding the first target operation mode, wherein the information is carried in at least one subfield of the first operation mode notification; and transiting, by the non-AP MLD, to the first target operation mode without transmitting additional management information regarding the first target operation mode to the first AP MLD.

  • Publication number: 20210203447
    Abstract: An apparatus identifies an onset of a coexistence scenario involving simultaneous transmission and receiving using a first wireless technology and a second wireless technology different from the first technology, respectively, in wireless communications with one other apparatus under a frequency-division duplexing (FDD) mode. The apparatus determines an upper limit on transmission rates responsive to identifying the onset of the coexistence scenario. The apparatus then performs transmissions at or without exceeding the upper limit until the coexistence scenario is over.

  • Patent number: 10104186
    Abstract: A device-centric discovery mechanism requiring very low power consumption to find out information about each other directly in a self-managed mobile environment is proposed. A mobile communications device joins a self-managed communications network, which does not have a centralized management entity. The mobile device receives a request from a peer communications device about publishing a service or subscribing to a service in accordance with a first schedule. The mobile device announce the request on behalf of the peer communications device in accordance with a second schedule. The service is then provided by a service advertiser to a service seeker in accordance with a third schedule.
