Abstract: Methods, systems, apparatus, and computer programs, for providing uplink control information to an access node. In one aspect, the method can include actions of determining, by a UE, a time-domain orthogonal cover code (OCC) for a PUCCH message of a UE to multiplex the PUCCH transmission with one or more PUCCH messages from one or more other UEs, and encoding, by the UE, the PUCCH message for transmission by the UE using the OCC.

Abstract: Technology for an eNodeB operable to decode a sounding reference signal (SRS) received from a user equipment (UE) is disclosed. The eNodeB can decode the SRS received from the UE, wherein 5 the SRS is received using one or more SRS resources in a subframe where each SRS resource includes one or more symbols. The subframe can be an uplink subframe dedicated for SRS transmission or a short transmission time interval (sTTI) subframe used for SRS transmission. The eNodeB can determine uplink channel quality information for a channel between the eNodeB and the UE based in part on the 10 SRS.

Abstract: Techniques discussed herein can facilitate reduced density CSI (Channel State Information)-RS (Reference Signals). One example embodiment can be employed at a UE (User Equipment) and can comprise processing circuitry configured to receive and process a configuration message that comprises one or more configuration parameters for one or more CSI (Channel State Information)-RS (Reference Signal) APs (Antenna Ports) of a configurable density CSI-RS. The configuration parameters indicate a density of CSI-RS resource per Physical Resource Block (PRB) per CSI-RS AP and a PRB offset. The processing circuitry is further configured to determine a set of REs (Resource Elements) for the one or more CSI-RS APs of the configurable density CSI-RS based on the one or more configuration parameters and perform measurements on the configurable density CSI-RS from the set of REs to determine one or more CSI parameters. The one or more configuration parameters are provided per CSI-RS resource configuration.

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: 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: 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.

Abstract: Described is an apparatus of an Evolved Node-B (eNB). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to determine a first Sounding Reference Signal (SRS) sequence and a second SRS sequence. The second circuitry may be operable to process a first Uplink (UL) transmission from the first UE incorporating the first SRS sequence over a first set of subcarrier frequencies. The second circuitry may also be operable to process a second UL transmission from the second UE incorporating the second SRS sequence over a second set of subcarrier frequencies. The second SRS sequence may comprise at least a first block that overlaps the first set of subcarrier frequencies and a second block that does not overlap the first set of subcarrier frequencies.

Abstract: Embodiments include apparatuses, methods, and systems that may be used in a UE in a mobile communication network to communicate with a gNB. An apparatus may include a memory and processing circuitry coupled with the memory. The processing in circuitry may cause coarse time and frequency synchronization information, obtained from primary and secondary synchronization signals (PSS/SSS), to be stored in the memory. Based on the coarse time and frequency synchronization information, the processing circuitry may decode a physical broadcast channel to obtain a first system information, and may acquire a second system information based on the first system information. Based on the first and second system information, the processing circuitry may cause a transmission of a PRACH, to trigger a transmission of a TRS by the gNB. Other embodiments may also be described and claimed.
