Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for enabling a single media access control (MAC) layer to control a variety of physical (PHY) layers or entities for multiplexing signals corresponding to each of the PHY layers over an air interface. Here, the MAC layer may include a resource manager configured to determine a time-frequency resource allocation within the air interface for communication with one or more subordinate entities utilizing each of the PHY layers. In this way, The MAC entity may provide dynamic control over the allocation of time-frequency resources within a given resource group, which may include transmission time intervals (TTIs) having multiple time scales.

Abstract: Methods and apparatus for supporting adaptive resource negotiation between evolved node Bs (eNBs) for enhanced inter-cell interference coordination (eICIC) are provided. This resource negotiation may occur via a network backhaul between the eNBs or, in some cases, using over-the-air messages (OAMs). For certain aspects, a first eNB may propose its adaptive resource partitioning information (ARPI) to a second eNB, where the second eNB may accept or reject the proposed resource partitioning. If the second eNB accepts the proposed partitioning, the second eNB may schedule resources, such as subframes, based on the accepted partitioning.

Abstract: Certain aspects of the present disclosure relate to techniques for configuring an adaptive frame structure for wireless communications systems using unlicensed radio frequency spectrum. A base station (BS) may determine whether another device is transmitting on a channel in the unlicensed radio frequency spectrum or one or more other network conditions pertaining to the channel, determine a frame structure from a plurality of frame structures used for data communications based at least in part on the one or more network conditions, wherein each of the plurality of frame structures has a different frame duration, and communicate with a user equipment (UE) using the determined frame structure. A UE may determine a frame structure from a plurality of frame structures used for data communications, wherein each of the plurality of frame structures has a different frame duration, and communicate with a BS using the determined frame structure.

Abstract: The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.

Abstract: Both precoded sounding reference signals (SRS) and unprecoded SRS are transmitted from a UE to an eNB. The UE may transmit both in the same subframe using either TDM or FDM. Or the UE may transmit each in different subframes from each other. The eNB uses some combination of the precoded SRS and the unprecoded SRS in scheduling resources for the UE. The eNB may also provide instruction to the UE for PUSCH precoding for data transmission. The eNB may signal the UE to use the same precoding as for the precoded SRS. The eNB may instead signal the UE to use different precoding by including the precoding information or delta information between the precoding used for the precoded SRS and the selected precoding for the PUSCH data.

Abstract: Techniques for wireless communications in a system with long term evolution (LTE) integrated with new radio (NR) are provided. A method for wireless communications includes determining a configuration of component carrier(s) (CCs) of a first radio access technology (RAT) and CC(s) of a second RAT. The method also includes identifying one of the CC(s) in the first RAT as an uplink anchor CC based on the configuration. The method further includes identifying a HARQ timing for at least one of the CC(s) of the second RAT based on at least one of a symbol duration, a transmit time interval (TTI) length or a subframe structure of the one of the CC(s) of the first RAT. The method further yet includes sending feedback to a second node in the identified uplink anchor CC for transmissions received in the CC(s) of the second RAT.
