Abstract: Apparatus and methods are provided for peer-to-peer communication network and multi-channel operation over OFDMA. In novel aspect, the communication device sends a first frame to reserve a time period for one or more peer-to-peer services in a wireless communication network, establishes one or more sessions with one or more peer-to-peer communication devices in the time period reserved for a subset of the one or more peer-to-peer services, transmits a second frame allocating radio resource for a subset of communications devices of the one or more communications devices, and sends or receives one or more data frames to/from one or more peer-to-peer communication devices concurrently using OFDMA, wherein the one or more data frames are received during the reserved time period. In one embodiment, the communication device is non-AP. In another embodiment, the second frame indicates resource blocks allocated for each of the one or more peer-to-peer communication devices.

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.

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.

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.
