    Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to enable the assigning of different listen-before-talk (LBT) priority classes or levels within a same DL transmission for scheduling UL transmissions, either in the same transmission opportunity as the UL grant or another transmission opportunity outside of the UL grant. Other data elements or traffic of the DL transmission can be multiplex with the UL grant, such as LBT parameters or a PUSCH, while each can be separately and selectively assigned different or equivalent LBT priority classes. The device can operate to process or generate communications on an unlicensed band or a licensed band in response to UL grants and indications provided via a DL transmission on a first transmission opportunity.

    Abstract: Techniques for contention window size (CWS) adaptation (CWSA) are discussed. One example apparatus can comprise a processor that can receive HARQ messages UEs in response to PDSCH transmissions in one or more reference subframes. The HARQ messages can comprise HARQ-ACK values that denote a HARQ-ACK state for a transport block associated with License Assisted Access (LAA) operation, wherein each of the HARQ-ACK states is one of a DTX state, an ACK state, a NACK state, or an “any” state. The processor can also; determine a metric value for each of the HARQ-ACK states; calculate a CWS adjustment metric based on the determined metric values; increase a CWS to a next higher allowed value when the CWS adjustment metric is greater than or equal to a threshold; and reset the CWS to a minimum allowed value when the CWS adjustment metric is less than the threshold.

    Abstract: This disclosure describes methods, apparatus, and systems related to receiver identification. A device may identify a data frame received from a first device, the data frame including one or more data fields. The device may decode the one or more data fields in the identified data frame using tail biting decoding having an initial decode state and an end decode state. The device may determine the received data frame is intended for the device based at least in part on the decoded one or more data fields.

    Abstract: Techniques discussed herein can facilitate RS (Reference Signal) sequence generation and mapping, and/or precoder assignment, for NR (New Radio). One example embodiment employable at a NR wireless communication device comprises processing circuitry configured to: generate one or more PN (Pseudo Noise) sequences based at least in part on an initial state of a PN generator; extract, for each PRB (Physical Resource Block) of one or more PRBs, an associated portion of an associated PN sequence of the one or more PN sequences, based at least in part on a reference subcarrier index, independent of a bandwidth part configuration and of a maximum supported number of PRBs; and generate, for each PRB of the one or more PRBs, an associated set of RS(s) for that PRB based at least in part on the extracted associated portion of the associated PN sequence for that PRB.

    Abstract: Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for license assisted access (LAA) communications on an unlicensed channel. The eNB determines if a subframe to be transmitted is a partial subframe, and if the subframe is not a partial subframe, constructs the subframe to contain both a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) at fixed symbol positions within the subframe. In further embodiments, the eNB determines if a last subframe of a downlink (DL) transmission burst to be transmitted is a partial subframe, and if the subframe is not a partial subframe, constructs the subframe to contain a discovery reference signal (DRS) for transmission.

    Abstract: Various embodiments may be generally directed to techniques for transmitting and receiving one or more reference signals opportunistically within a window over an unlicensed carrier. Various embodiments provide techniques for determining a configuration of the window within an operating environment that may include one or more different radio access technologies (RATs). Various embodiments provide techniques for transmitting the one or more reference signals opportunistically within the window based on an availability of a wireless communications medium. Various embodiments provide techniques for receiving and recovering the one or more reference signals regardless of their location within the window, thereby improving communications in an unlicensed spectrum shared by a variety of different communication devices that may operate according to a variety of different communication protocols.

    Abstract: Techniques for mobile communication in an unlicensed frequency band are discussed. A network device (e.g., an evolved NodeB, or other cell network device) can generate a listen before talk (LBT) protocol in order to determine whether an unlicensed carrier of a secondary cell device is idle or busy. The LBT protocol can be generated as a one shot LBT within a two symbol duration of a potential downlink (DL) transmission burst, or multiple times within the two symbol duration. In response to an idle state detection, a discovery reference signal (DRS) can be transmitted. In response to the LBT protocol and the DRS transmission being misaligned, a reservation signal can be generated to reserve the unlicensed carrier for the DL transmission.

    Abstract: 5G methods and architectures to determine active SCells and their bandwidth parts (BWP) used in carrier aggregation (CA) are disclosed in which activating a BWP for an active SCell is performed initially according to a default value provided in initial radio resource control (RRC) messaging. After initialization, SCells and the SCell BWPs used by the user equipment (UE) are activated by RRC messaging, downlink control information (DCI) or dedicated medium access control (MAC) control elements (MAC CEs) with the initial BWP used for an activated SCell being a default value provided during initialization.
