Abstract: Systems, methods, and instrumentalities are disclosed for concurrent link setup and downlink data retrieval, e.g., for high efficiency WLAN. An access point (AP) may send a trigger element that allocates a resource for pre-association transmissions with the AP. The trigger element may allocate the resource for random access and/or deterministic access. The AP may receive, from an unassociated STA, a first frame via one or more resource units (RUs) allocated in the trigger element. The AP may determine a pre-association identifier (PID) that identifies the unassociated STA. The AP may send the PID to the unassociated STA, for example, in the trigger element or in the multi-STA ACK. The AP may send a second frame associated with a multi-user (MU) transmission that includes the PID. The AP may send a trigger frame that includes the PID.

Abstract: Methods, systems, and devices for wireless communications are described that provide for allocation of control channel candidates for multiple component carriers (CCs) in carrier aggregation (CA) communications. A CA limit may correspond to a total number of configurable control channel candidates across multiple CCs. The control channel candidates may include blind decoding (BD) candidates or control channel element (CCE) candidates for channel estimation. A per-CC limit of control channel candidates may correspond to a number of configurable control channel candidates for each CC. An applied set of control channel candidates may be determined by allocating control channel candidates across the multiple CCs based on the CA limit and the per-CC limit. Such techniques may be used in cases where the CCs have a same numerology or mixed numerology, and may also be used for cross-carrier scheduling.
