Abstract: Wireless communication devices, such as a scheduled entity, are adapted to facilitate uplink transmissions on multiple physical uplink control channels (PUCCHs) of a regular burst period. According to one example, a scheduled entity may obtain a payload for an uplink transmission on a PUCCH. The scheduled entity may subsequently send the uplink transmission utilizing two or more physical uplink control channels (PUCCH) of a regular burst period, where each PUCCH is associated with a different frequency band of the regular burst period. According to one example, a scheduling entity may receive an uplink transmission, where the uplink transmission utilizes a first PUCCH of a regular burst period, and at least a second PUCCH of the regular burst period, each of the first and second PUCCHs being associated with respectively different frequency bands of the regular burst period. Other aspects, embodiments, and features are also included.

Abstract: Discovery and synchronization channels are discussed for user-tracking zones in a cellular network. User-tracking zones reduce the mobility tracking burden on the UE and shift the tracking responsibility to the network. This shift allows for UE and network power savings from reduced searching at the UE as well as through efficient paging area tracking and less broadcast signaling. The various aspects provide channel design for initial synchronization and discovery of the user-tracking zones. A single frequency network (SFN) synchronization channel is provided with at least a reference signal for time synchronization and payload information that may include a zone identifier (ID), formatting for a system information transmission request, and resource allocation for the request. The zone ID may be included in the payload or embedded into the reference signal. Facility is also provided for handling zone nodes of different power classes that allows for maintaining the SFN operations.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Systems and methods for communicating mission-critical (MiCri) data in a network including a base station and user equipment (UE) are provided. The methods may include receiving a request message requesting MiCri data, and transmitting the MiCri data during a transmission time interval (TTI) of a first carrier component or during a transmission time interval (TTI) of a second carrier component. In various aspects, the TTI of the first carrier component may be staggered in time with respect to the TTI of the second carrier component. In another aspect, the UE may pre-report interference pattern information for a nominal TTI for use in communication of MiCri data.

Abstract: Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.

Abstract: Aspects of the present disclosure provide techniques and apparatus for enhancing performance by selectively applying averaging to CSI reporting processes. According to certain aspects, a base station (e.g., an eNB) with knowledge of traffic patterns of potentially interfering transmitters may signal a UE how (or whether) to apply averaging, for example, when reporting CSI based on interference measurement resources (IMR).

Abstract: Resource mapping and coding schemes to handle bursty interference are disclosed that provide for spreading the modulated symbols for one or more transmission code words over more symbols in the time-frequency transmission stream. Certain aspects allow for the modulated symbols to be based on bits from more than one code word. Other aspects also provide for re-mapping code word transmission sequences for re-transmissions based on the number of re-transmissions requested by the receiver. Additional aspects provide for layered coding that uses a lower fixed-size constellation to encode/decode transmissions in a layered manner in order to achieve a larger-size constellation encoding. The layered encoding process allows the transmitter and receiver to use different coding rates for each coding layer. The layered encoding process also allows interference from neighboring cells to be canceled without knowledge of the actual constellation used to code the interfering neighboring signal.

Abstract: Aspects of the present disclosure describe discovering physical cell identifiers in wireless communications. It can be determined to discover a physical cell identifier of one or more cells in a zone based at least in part on detecting a condition. A cell-specific signal can be received from at least one cell of the one or more cells in the zone. The cell-specific signal can be associated with one of a plurality of possible scrambling codes or sequences. The physical cell identifier of the at least one cell can be determined as one of a plurality of physical cell identifiers that corresponds to the one of the plurality of possible scrambling codes or sequences.

Abstract: Methods and apparatus for wireless communication are described. A method may include receiving at a user equipment (UE) a number of allocated interlaces for an uplink transmission over a shared spectrum, each of which may include a plurality of non-contiguous resource blocks (RB) of the shared spectrum. In some cases, the number of allocated interlaces is unsupported by joint interlace precoding hardware of the UE and the allocated interlaces may be partitioned into subsets of interlaces which may be a size supported by the joint interlace precoding hardware. Reference signals may be generated for the RBs of the allocated interlaces according to a reference signal sequence based on an ordering of the RBs for the allocated interlaces within the shared spectrum.

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.
