Abstract: A station that performs a method to coordinate transmissions of scheduling requests (SR) with OnDurations of a connected discontinuous reception (C-DRX) cycle. The station receives a packet at a packet arrival time relative to a schedule indicating the SR opportunities and onDurations, the SR opportunities occurring at a first interval, the onDurations occurring at a second interval, the first interval being less than the second interval. The station determines an SR opportunity subsequent to the packet arrival time that precedes an entirety of a subsequent onDuration, such that a transmission duration to transmit the SR and the packet maximally overlaps with the selected onDuration. A sleep mode of the processor of the station is used until a time associated with the selected SR opportunity. An active mode of the processor is used to transmit the SR and receive control channel information during the onDuration.

Abstract: The disclosure describes apparatus and methods for communicating control plane data with a mobile device in a Long Term Evolution (LTE) network employing carrier aggregation. A network apparatus, such as an enhanced NodeB (eNodeB) or a mobility management entity (MME), can be configured to evaluate a measurement report (MR) received from a mobile device for one or more radio frequency (RF) conditions associated with a primary network cell and one or more RF conditions associated with a secondary network cell. Then, based on the evaluation, the network apparatus can determine to communicate the control plane data with the mobile device via the primary network cell, the secondary network cell, or both. The control plane data can correspond to non-access stratum (NAS) information, radio resource control (RRC) information, or a hybrid automatic repeat request (HARQ) retransmission of previously transmitted control plane data.

Abstract: In some embodiments, a user equipment device (UE) may be configured to perform handover of a communication session from a first packet data network (PDN) to a second PDN. The UE may include a radio and processing circuitry coupled to the radio and configured to interoperate with the radio. The radio may include one or more antennas for performing wireless communications over at least a first packet data network (PDN) (i.e., packet-switched network) and a second PDN. The UE may be configured to communicate over the first PDN according to first context information that was assigned to the UE and initiate a handover operation from the first PDN to the second PDN. In response to initiating the handover operation, the UE may communicate over the second PDN using the first context information for at least a first time duration.

Abstract: A wireless communication system is presented in which user equipment (UE) performs non-intra-frequency (NIF) cell reselection. The NIF cell reselection process can: detect, on a discontinues reception (DRX) cycle, whether a NIF for a second cell has passed a second reselection threshold; perform, on the DRX cycle, additional checks or measurements to determine whether a higher priority NIF for a third cell has passed a third reselection threshold; and continue a cell reselection process for the second cell and the third cell. The NIF cell reselection techniques can help ensure that the UE reselects to higher priority cells without expending an unnecessary amount power.

Abstract: Performing cell re-selection by a device. A first cell on which to camp may be selected. The device may camp on the first cell in an idle-mode. The device may be configured to perform searches for neighboring cells according to an idle-mode timeline while camping on the first cell. The device may transmit a connection request to the first cell in order to transition the device from the idle-mode to a connected-mode via the first cell. One or more searches for neighboring cells may be performed according to a connected-mode timeline after transmitting the connection request, in response to transmitting the connection request. The one or more searches may be performed before the device establishes the connected-mode with the first cell.

In one embodiment, the data is raw audio data and the data packets are audio packets.

Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.

Abstract: Apparatus, system and methods for evaluating link quality within a cellular system. A user equipment (“UE”) is connected to a network, wherein the UE communicates data to the network on an uplink (“UL”) link. The UE determines a requested buffer size for a UL communication, determines a transport block size for the UL communication based on a primary set of allocation parameters, and compares the requested buffer size to the transport block size to determine if a data rate for the UL communication satisfies a threshold. When the data rate satisfies the threshold, the UE identifies the UL link as a good quality link and sends acceptable link quality feedback to the network. When the data rate does not satisfy the threshold, the UE performs a further action to test a quality of the UL link.

Abstract: A method for reducing scheduling requests by a wireless communication device transmitting data using dynamically scheduled resources over a logical channel is provided. The method includes receiving, at the wireless communication device, a configuration from a network entity that sets a LogicalChannelSR-Mask for a logical channel for which uplink resources can be dynamically scheduled by the wireless network. The method further includes waiting to send a scheduling request (SR) for a delay time period when data is available to be sent on the logical channel and uplink resources have not been granted. The method additionally includes using the grant to send the data without sending an SR when a grant is received within the delay time period; or sending an SR when a grant is not received within the delay time period. In another method, a network selectively enables or disables SRs for a logical channel through explicit signaling.
