Abstract:
Embodiments of an eNB to operate in accordance with a coverage enhancement mode are disclosed herein. The eNB may comprise hardware processing circuitry to, during a legacy sub-frame, transmit a system information block (SIB) in legacy SIB frequency resources according to a legacy SIB transmission format and refrain from transmission of channel state information reference signals (CSI-RS). The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first portion of the SIB in first SIB frequency resources included in the legacy SIB frequency resources. The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first set of CSI-RS in first CSI-RS frequency resources that include at least a portion of the legacy SIB frequency resources.
Abstract:
A user equipment (UE) for time division duplex (TDD) communication through a wireless communication channel has a receiver to receive a channel state information reference signal (CSI-RS) subframe configuration value, a CSI-RS configuration value, and a CSI-RS; and circuitry to determine a subframe index corresponding to a temporal position of a special subframe including the CSI-RS; determine a CSI-RS pattern of one or more orthogonal frequency division modulation (OFDM) resource elements carrying the CSI-RS, the pattern being from among a group of CSI-RS patterns that include OFDM resource elements in OFDM symbols corresponding to a physical downlink control channel (PDCCH) region of a legacy LTE wireless communication channel; control the receiver to receive the special subframe carrying the CSI-RS during the temporal position and at the one or more OFDM resource elements of the CSI-RS pattern; and measure the wireless communication channel based on the CSI-RS.
Abstract:
Embodiments of an enhanced node B (eNB) and methods for network-assisted interference cancellation with reduced signaling in a 3GPP LTE network are generally described herein. In some embodiments, the number of transmission options is reduced by introducing a smaller signaling codebook. In some embodiments, higher-layer feedback from the UE to the eNodeB is established to inform the eNB about certain NA-ICS capabilities of the UE. In some embodiments, the number of signaling options is reduced by providing only certain a priori information. In some embodiments, correlations in the time and/or frequency domain are exploited for reducing the signaling message. In some embodiments, differential information is signaled in the time and/or frequency domain for reducing the signaling message.
Abstract:
An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to generate one or more signals for transmission to a user equipment (UE) device, wherein the UE device has a plurality of antenna panels; receive a beam state report from the RF interface from the UE device; select beams for communication with one or more of the plurality of antenna panels based on the received beam state report.
Abstract:
Methods and architectures to reduce latency in next generation wireless networks such as LTE and/or new radio (NR), includes adjusting hybrid automatic repeat request (HARQ) techniques to selectively skip acknowledgements (ACKs) in various embodiments, and to configure one or more code block groups (CBG) designating code blocks for retransmission according to a code block group index bitmap present in received downlink control information (DCI).
Abstract:
Provided herein are method and apparatus for configuration of a Reference Signal (RS) and a Tracking Reference Signal (TRS). An embodiment provides an apparatus for an access node including a radio frequency (RF) interface; and processing circuitry configured to: determine a time density of a Tracking Reference Signal (TRS) based on a subcarrier spacing of a bandwidth part (BWP) in a current component carrier for a user equipment (UE); determine a frequency density of the TRS based on a bandwidth of the TRS; determine a quasi co-location (QCL) relationship of the TRS; and encode the TRS based on at least one of the time density, the frequency density and the QCL relationship for transmission to the UE via the RF interface. At least some embodiments allow for beam management, and allow for fine time and/or frequency offset tracking.
Abstract:
Systems and methods of beam reporting for multiple DL processes are described. A UE receives a beam management processes configuration that provides information about beam management reference signals for beam management procedures. The UE transmits a UE capability report that indicates beam management capabilities of the UE and, later, an indication of whether the UE intends to engage in beam refinement. The UE measures the beam management reference signals and receives a beam reporting message that indicates at least one of the beam management procedures to report. In response, the UE transmits the beam report. The beam report contains beam management reference signal measurements of the beam management procedures indicated by the beam reporting message.
Abstract:
Technology for a user equipment (UE) operable to identify downlink control channel candidates for receiving downlink control channel information is disclosed. The UE can decode a downlink control information (DCI) format received from an eNodeB. The DCI format can indicate a set of resource blocks (RBs) in one or more subframes allocated for reception or transmission of data or control information in a shortened transmission time interval (S-TTI). The UE can identify a subset of resource elements (REs) within the set of RBs in the one or more subframes. The subset of REs can correspond to shortened physical downlink control channel (S-PDCCH) candidates in the S-TTI of one or more subframes. The UE can attempt to decode the S-PDCCH candidates in the S-TTI of the one or more subframes. S-PDCCH candidates that are successfully decoded can cause the UE to identify the downlink control information.
Abstract:
An apparatus configured to be employed in a victim transmission reception point (TRP) associated with a new radio (NR) communication system is disclosed. The apparatus comprises a memory interface and a processing circuit. In some embodiments, the processing circuit is configured to process one or more predefined interference signals respectively received from one or more interfering TRPs during a guard period of the victim TRP. In some embodiments, the guard period comprises a time period between a downlink (DL) transmission and an uplink (UL) transmission associated with a time division duplex (TDD) frame of the victim TRP. In some embodiments, the processing circuit is further configured to determine an inter-TRP interference based on the one or more predefined interference signals. In some embodiments, the inter-TRP interference comprises a measurement of a UL interference at the victim TRP from the one or more interfering TRPs.
