    Abstract: Apparatus and methods for time division based communication between a wireless device and a wireless network in a licensed radio frequency (RF) band and an unlicensed RF band are disclosed. The wireless device receives downlink control information (DCI), via a primary component carrier (PCC) of a primary cell (Pcell) in the licensed RF band, indicating downlink (DL) data transmission via a secondary component carrier (SCC) of a secondary cell (Scell) in the unlicensed RF band. The wireless device receives via the SCC part of the DL data transmission and transmits a control message via the PCC in response. The wireless device sends a scheduling request (SR) to the eNodeB and receives uplink (UL) transmission opportunities in a combination of the licensed RF band and the unlicensed RF band. The wireless device performs a clear channel assessment before reserving and transmitting to the eNodeB in the unlicensed RF band.

    Abstract: A station (STA) of a wireless local area network (WLAN) transitions implicitly between power management (PM) modes or PM states, without providing an explicit indication of the PM mode/state change to an access point (AP) of the WLAN. Transitions include changes between an active mode and a power save (PS) mode, or between an awake state and a doze state of the PS mode. Transitions occur immediately after receipt of a beacon indicating pending data for the STA, after an offset time indicated in the beacon, or at a specific wake time negotiated with the AP. After data reception is complete, the STA transitions implicitly to the PS mode or a doze state of the PS mode, after a power save inactivity timeout period or after receiving an indication that data transmission is complete.

    Abstract: The disclosure describes procedures for allocating network resources for a mobile device communicating within a Long Term Evolution (LTE) network. The mobile device can be configured to decode a physical downlink shared channel (PDSCH), acquire first and second physical downlink control channel (PDCCH) decode indicators from a payload of the same PDSCH communication, decode a PDCCH for downlink control information (DCI) associated with a first application data type based on the first PDCCH decode indicator a second application data type based on the second PDCCH decode indicator. The first PDCCH decode indicator can identify an upcoming LTE subframe where the mobile device is required to decode the PDCCH for DCI associated VoLTE resource assignments and the second PDCCH decode indicator can identify an upcoming LTE subframe where the mobile device is required to decode the PDCCH for DCI associated with high bandwidth best effort (BE) data resource assignments.

    Abstract: In order to reduce power consumption of an electronic device during communication with another electronic device in a wireless local area network (WLAN), the electronic device analyzes fields in a given packet prior to a payload of the given packet to look for information that specifies a destination of the given packet. For example, the information may include: a full associated identification (AID) of the destination, a partial media-access-control (MAC) address of the destination; and/or a compressed (MAC) address of the destination. The information may be included in the preamble of the given packet. In particular, the information may replace length information in a high-throughput signal field in the given packet. Moreover, if the destination is other than the electronic device, the electronic device dumps the given packet and changes a power state of the electronic device, thereby reducing the power consumption.

    Abstract: Apparatus and methods for a hybrid automatic repeat request (H-ARQ) mechanism for wireless communication devices of a wireless local area network (WLAN) are disclosed. Methods and apparatus to determine whether a packet is an original, first transmission or a retransmission of a previously transmitted packet without decoding the payload of the packet are disclosed. Medium access control (MAC) addresses of a transmitter, such as an access point (AP), and a receiver, such as a station (STA), of a WLAN are encoded separately with a retransmission bit to indicate whether the packet is retransmitted. For an aggregated MAC protocol data unit (A-MPDU), a sequence number is included to determine which MAC protocol data units (MPDUs) of the A-MPDU are retransmitted. When retransmission is indicated, the receiver of the STA performs a hybrid automatic repeat request (H-ARQ) process to combine the retransmitted packet with previously received packets.
