Abstract:
Systems and methods for controlling data traffic offload to a WLAN (e.g., a Wi-Fi network) from a WWAN (e.g., a 4G LTE network) are generally disclosed herein. One embodiment includes data traffic offload techniques managed by a Radio Resource Control (RRC) in a networked device including offloading data at the IP, PDCP, RLC, or MAC layers; another embodiment includes data traffic offload techniques managed by a MAC Scheduler with RRC control. Configurations for multimode user equipment (UE) and multimode base stations are also described herein, including configurations for implementing a Multiple Radio Access Technology (Multi-RAT) aggregation function to offload data from a WWAN to a WLAN and transmit the data via the WLAN using a Layer 2 transport.
Abstract:
Embodiments herein describe apparatuses, systems, and methods for signaling to support downlink coordinated multipoint (CoMP) communications with a user equipment (UE) in a wireless communication network. In embodiments, the UE may be configured with a plurality of channel state information (CSI) processes (e.g., via radio resource control (RRC) signaling) to use for providing CSI feedback to an evolved Node B (eNB) to support downlink CoMP communications. The UE may be configured with a plurality of sets of CSI processes. The UE may further receive a downlink control information (DCI) message from the eNB that indicates one of the configured sets of CSI processes on which the UE is to provide CSI feedback to the UE. The UE may generate the CSI feedback for the indicated set of CSI processes, and transmit the CSI feedback to the eNB in a CSI report.
Abstract:
Briefly, in accordance with one or more embodiments, a user equipment (UE) is configured to inform an evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (EUTRAN) that the UE will receive Multimedia Broadcast Multicast Services (MBMS) services on an MBMS carrier, switch from a primary serving cell to the MBMS carrier to receive MBMS services, and switch back to the primary serving cell after reception of the MBMS services from the MBMS carrier.
Abstract:
Methods, apparatuses, and systems are described related to interference averaging to generate feedback information and interference averaging to demodulate receives signals. In embodiments, an evolved Node B (eNB) may transmit interference averaging information to a user equipment (UE) including a time domain averaging indicator indicating a time domain averaging window to be used by the UE for averaging interference measurements in a time domain or a frequency domain averaging indicator to indicate a frequency domain averaging window to be used by the UE for averaging interference measurements in a frequency domain. Additionally, or alternatively, the eNB may transmit an interference resource group (IRG) indicator to the UE to indicate an IRG over which the UE is to perform interference averaging to facilitate demodulation of signals received by the UE from the eNB.
Abstract:
Disclosed embodiments may include an apparatus having one or more processors coupled to one or more computer-readable storage media. The one or more processors may be configured to transmit and/or receive channel state information reference signal (CSI-RS) resource configuration information, demodulation reference signals (DM-RS), uplink sounding reference signals (SRS), and power control parameters to support uplink coordinated multi-point (CoMP) operations. Other embodiments may be disclosed.
Abstract:
Coordinated Multipoint (CoMP) involves multiple transmission points or cells coordinating their individual transmissions so that a target user equipment (LTE) experiences enhanced signal reception and/or reduced interference. In order to optimally implement downlink CoMP, a serving cell needs to obtain channel state information (CSI) for the downlink channels from the multiple transmission points to the UE. This disclosure deals with radio resource control (RRC) signaling for configuring the UE to obtain and report CSI for those downlink channels.
