Abstract: Herein described are apparatuses, systems, and methods for measurement and reporting of channel state information within wireless network systems. In embodiments, an apparatus for a user equipment (UE) may include memory to store a rank indicator (RI), a precoding matrix index (PMI), and a channel quality indicator (CQI) of channel state information (CSI) for the UE. The apparatus may further include circuitry to concatenate the RI, the PMI, and the CQI to produce a concatenated CSI element, generate a CSI report that includes the concatenated CSI element, and cause the CSI report to be transmitted to a base station within a single slot. Other embodiments may be described and/or claimed.

Abstract: Techniques for measuring CSI (Channel State Information) based on beamformed CSI-RS having reduced overhead are discussed. One example embodiment configured to be employed in a UE (User Equipment) comprises a memory; and one or more processors configured to: process higher layer signaling indicating one or more CSI-RS resources associated with a plurality of REs (Resource Elements) comprising a RE for each CSI-RS resource for each of one or more CSI-RS APs (Antenna Ports) in each of a plurality of continuous PRBs (physical resource blocks); process additional higher layer signaling comprising one or more CSI-RS parameters that indicate a subset of the plurality of REs associated with a beamformed CSI-RS transmission; decode one or more CSI-RSs from the indicated subset; and measure one or more CSI parameters based on the decoded one or more CSI-RSs.

The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a Downlink (DL) transmission carrying one or more Phase Tracking Reference Signal (PT-RSes).

Abstract: A user equipment (UE) may assess a radio link quality of a plurality of frames for communication, via the interface to the RF circuitry, with a radio access network (RAN) node. When the radio link quality of a frame, of the plurality of frames, is below an out-of-sync (OOS) threshold, the UE may indicate that the frame is OOS. When the radio link quality of a frame, of the plurality of frames, is above an in-sync (IS) threshold that the frame is IS. Additionally, or alternatively, the UE may process information, received from the RAN node indicating a partial subframe, of a subframe, to be used to transmit uplink control information (UCI) to the RAN node. The UE ma also perform UCI mapping for using of the partial subframe to transmit UCI via a physical uplink control channel (PUSCH), and proceed by using the partial subframe to communicate the UCI to the RAN node.

Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. If a higher layer parameter altMCS-Table is configured, and a physical downlink shared channel (PDSCH) is assigned by a downlink control information (DCI) format 1, 1B, 1D, 2, 2A, 2B, 2C, or 2D, the UE may, for some subframe/frame configurations, determine a number of physical resource blocks (PRBs) for the transport block as a maximum of: 1; and a floor function applied to a product of a total number of allocated PRBs, a parameter dependent on a special subframe configuration, and a scaling parameter. For other subframe/frame configurations, the UE may determine the number of PRBs for the transport block as a maximum of: 1; and the floor function applied to a product of the total number of allocated PRBs and the scaling parameter.

Abstract: Examples include techniques for determining power offsets of a physical downlink shared channel (PDSCH). In some examples higher and physical layer signaling may be provided to user equipment (UE) by a base station such as an evolved Node B to enable the UE to determine power offset values for a multiplexed PDSCH having a serving PDSCH and a co-scheduled PDSCH transmitted via use of same time and frequency resources. The determined power offset values for use by the UE to demodulate the serving PDSCH and mitigate possible interference caused by the co-scheduled PDSCH. Both the UE and the eNB may operate in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards.

Abstract: Systems, methods, and circuitries are disclosed for determining Precoding Resource Block Groups (PRGs). In one example, a processor of a base station (BS) is configured to determine a plurality of PRGs that includes a number N consecutive Physical Resource Blocks (PRBs) over which a same precoder assignment is used, starting from a reference PRB. The plurality PRGs include a first boundary PRG, a second boundary PRG, and one or more other PRGs. The first boundary PRG is located at an upper boundary of a bandwidth part. The first boundary PRG comprises fewer than N PRBs when the upper boundary of the bandwidth part is not aligned with a PRG boundary. The second boundary PRG comprises fewer than N PRBs when a lower boundary of the bandwidth part is not aligned with a PRG boundary. A downlink data channel is transmitted to a UE in accordance with the precoder assignments.
