Abstract: A fill-duplex (FD) capable access point (AP) of a wireless basic service set (BSS) that includes a plurality of stations (STAs) is configured to implement opportunistic FD downlink (DL) transmissions to a non-FD capable STA in the BSS when decoding uplink (UL) data from a UL STA in the BSS. While decoding the UL data, the AP selects a DL STA from a queue of DL STAs based on a predetermined FD DL transmission rate from the AP to the DL STA while the AP is decoding the UL data from the UL STA. The AP then causes an amount of data to be transmitted as an FD transmission to the selected DL STA while the processor is decoding the data from the UL STA.

Abstract: Methods adapted for measuring interference in joint communications and Access Points (APs) are described. The interference can be between the AP and first and second communication stations (STAs). In a method to measure interference, a first communication between the AP and the first STA can be established. Further, a second communication between the AP and the second STA can be established. The second communication can include transmitting a null data packet (NDP) to the second STA based on the first communication to measure STA-to-STA inference between the first STA and the second STA.

Abstract: An apparatus and method for flexible adjustment of the uplink-downlink ratio configuration for each enhanced node B (eNodeB) within a wireless communications network is disclosed herein. In one embodiment, a given eNodeB is configured to determine a current or subsequent uplink-downlink ratio configuration for a pre-determined time period. The determined current or subsequent uplink-downlink ratio configuration is encoded into a special physical downlink control channel (PDCCH), the special PDCCH included in at least one radio frame according to the pre-determined time period. The radio frame including the special PDCCH is transmitted to user equipment served by the given eNodeB.

Abstract: Methods for allocating a physical downlink control channel (PDCCH) to reduce a number of PDCCH candidates in a search space for carrier aggregation on a user equipment (UE) are disclosed. The method comprises the step of selecting a control channel element (CCE) aggregation level for a PDCCH allocation for each of a plurality of user equipments (UEs) at an evolved NodeB (eNB). The operation of identifying a transmission mode for each of a plurality of component carriers (CCs) associated with the PDCCH at the eNB follows. The next operation of the method is assigning each CC's downlink control information (DCI) into CCEs in a PDCCH search space in the PDCCH starting at a CCE location based on the CC's transmission mode and the CCE aggregation level for the UE receiving the CC.

Abstract: Aspects of mmWave beam tracking and beam sweeping are described, for example, spatial searching operations, directional beam forming, complex channel measurement operations, and adaptive power savings. Some aspects include using priori information for mmWave beam tracking and beam sweeping. Some aspects include using priori information to modify a superset of beam criteria to obtain a subset of beam criteria, select a spatial region according to the subset of beam criteria, and initiate a spatial searching operation within the spatial region for establishing a communication link. Some aspects include obtaining complex channel measurements of beams and combining the measurements with priori information to determine a beam for use in a communication link. Some aspects include providing signals from Nr over K1 input/output (IO) links and receiving signals over K1 IO links, and combining signals received over the K1 IO links, using a compression matrix, to generate signals over K IO links.
