Abstract: Technology for a user equipment (UE) using a self-contained time division duplex (TDD) subframe to communicate with an eNodeB within a wireless communication network is disclosed. The UE can determine, at the UE, an advanced physical uplink control channel (xPUCCH) resource index to designate one or more physical resources for transmission of the xPUCCH, wherein the one or more physical resources are multiplexed using at least one or more of frequency division multiplexing (FDM), code division multiplexing (CDM), or combination thereof. The UE can signal a transceiver of the UE to transmit to the eNodeB up link control information (UCI) using the one or more physical resources designated by the xPUCCH resource index.

Abstract: A base station may generate first configuration information to configure a first user equipment (“UE”) to operate using a first bandwidth within a wideband carrier of a cell, generate second configuration information to configure a second UE to operate using a second bandwidth within the wideband carrier of the cell, and cause transmission of the first and second configuration information to the first and second UEs, respectively. The base station may configure the first and second UEs based upon capabilities received from each UE, respectively.

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: Methods, apparatus, and systems are provided for signalling transmissions using carriers of different numerologies. In one example, a baseband processor of a base station is configured to perform operations including encoding a first signal to be transmitted on a physical downlink control channel (PDCCH) on a first component carrier with a first subcarrier spacing. The first signal includes downlink control information (DCI) indicating resources for a second signal to be transmitted on a second component carrier with a second subcarrier spacing. Respective numerologies of the first component carrier and the second component carrier are different from one another in accordance with the first subcarrier spacing and the second subcarrier spacing. The baseband processor is configured to cause transmission of the first signal on the PDCCH.

Abstract: Technology for a user equipment (UE) operable to encode a New Radio (NR) short duration physical uplink control channel (PUCCH) for transmission to a Next Generation NodeB (gNB) is disclosed. The UE can identify uplink control information (UCI) for the UE. The UE can multiplex, using frequency division multiplexing (FDM) at the UE, the UCI and a pseudo-random sequence associated with a demodulation reference signal (DMRS) onto a plurality of subcarriers in one or more physical resource blocks (PRBs) of one or more orthogonal frequency division multiplexing (OFDM) symbols. The UE can encode the UCI and the pseudo-random sequence associated with the DMRS multiplexed onto the plurality of subcarriers of the one or more OFDM symbols for transmission on the NR short duration PUCCH to the gNB.

Abstract: Techniques discussed herein can facilitate multi-transmission reception point (multi-TRP) operation for new radio (NR). One example apparatus may be employed at a user equipment (UE), and may comprise: an interface configured to enable the UE to communicate with two or more TRPs; and a processor that is configured to generate uplink control information (UCI) for each of the TRPs, schedule single or multiple uplink channels to carry the UCI, so that the UCI is transmitted individually or in combination to the TRPs via the interface, wherein the uplink channels comprise NR physical uplink control channel (PUCCH) and/or NR physical uplink shared channel (PUSCH). Techniques discussed herein also can facilitate demodulation reference signal design for short physical uplink control channel carrying more than 2-bit UCI for new radio.
