Abstract: Aspects of the disclosure relate to a transmitting device, which may explicitly or implicitly signal the use of continuous precoding for a resource block (RB) cluster. For example, the transmitting device may implicitly indicate that continuous precoding is applied to an RB cluster by dynamically controlling one or more parameters of a transmission over those RBs. Further, when continuous precoding is applied to an RB cluster, the transmitting device may explicitly or implicitly signal the dynamic control over one or more transmission properties, with an aim to maximize the benefits of such continuous precoding. Other aspects, embodiments, and features are also claimed and described.

Abstract: Enhanced channel state information (CSI) procedures for full dimension-multiple input, multiple output (FD-MIMO) is discussed in which a number of CSI reference signal (CSI-RS) ports configured for a user equipment (UE) is determined. In response to the CSI-RS ports including both horizontal and vertical ports, the UE may determine a first precoding matrix from a plurality of precoding matrices constructed by a Kronecker product of a horizontal precoding matrix and a vertical precoding matrix. The UE selects a predetermined number of precoding vectors out of the first precoding matrix and generates a wideband precoding matrix, based on the selected predetermined number of precoding vectors. The UE reports one or more CSI reports, wherein the CSI re-ports includes at least one precoding matrix indicator (PMI) for the first precoding matrix and at least an indication of the selection of the predetermined number of precoding vectors.

Abstract: Aspects described herein relate to communicating in a wireless network. Downlink control information having a dynamic resource allocation indicator can be received from a serving access point. It can be determined whether the dynamic resource allocation indicator indicates at least one symbol in a subframe is for uplink data communications or reference signal transmission. Uplink data communications can be transmitted using the at least one symbol based at least in part on the determination that the dynamic resource allocation indicator indicates the at least one symbol in the subframe is for the uplink data communication, though a broadcasted reference signal configuration may indicate otherwise. Numerous other aspects are provided.

Abstract: The present methods and apparatus enable transmission of an interlaced reference signal for two UEs using a comb structure. In some aspects, the present methods and apparatus may allocate resources and indicate whether a first UE and a second UE are to transmit DM-RS with a comb structure in a single slot based on the allocation. Further, in some aspects, the present methods and apparatus may allocate resources and transmit information indicating whether a first UE is to transmit DM-RS in a first slot or in both a first slot and a second slot within a subframe.

Abstract: Methods, systems, and devices for indicating a modulation coding scheme (MCS) in LTE are described. A user equipment (UE) may receive downlink control information (DCI) from an evolved Node B (eNB) that includes an uplink grant of resources. The DCI may be configured and have a format that conveys an MCS table reference. The UE may identify the MCS table reference and, based on the reference, identify a legacy MCS table or a non-legacy MCS table. The legacy MCS table may be associated with quadrature amplitude modulation (QAM) up to a first order, and the non-legacy MCS table may be associated with QAM up to a second order, the second order being higher than the first order. The UE may modulate and code information for uplink transmissions using the identified MCS table.

Abstract: Techniques are described for wireless communication. One method includes detecting a first reference signal received from a user equipment (UE) in a reference scheduled transmission burst including a plurality of contiguous transmission time intervals (TTIs) received over a shared radio frequency spectrum band; identifying a reference TTI in which the first reference signal is received; determining a contention window size usable by the UE to contend for access to the shared radio frequency spectrum band; and transmitting an indication of the determined contention window size to the UE.

Abstract: Methods, systems, and devices for wireless communication are described that provide for sharing or isolating network resources between multiple cells in a system. Resources are allocated to multiple cells and multiplexed according to a time division multiplexing (TDM) scheme where a portion of a component carrier is shared between multiple cells. The allocation of resources also includes splitting or sharing a portion of the time resources between two or more cells such that a subframe is allocated as a subframe shared between multiple cells or as a subframe dedicated for use by only a single cell.

Abstract: Multiple base stations or transmit points (TPs) may use single-user multiple-input multiple-output (SU-MIMO) layer-specific and codeword-specific communication configurations for non-coherent joint transmissions (NCJTs) to a user equipment (UE). Two TPs may be configured for NCJTs to the UE, and one or more of the TPs may transmit a set of communication configurations to the UE. The communication configurations may be transmitted in a single downlink control information (DCI) transmission that configures the UE to receive NCJTs as two codewords in a SU-MIMO transmission. The UE may receive the DCI, receive the multiple NCJTs, and demodulate/decode the NCJT transmissions as multiple codewords in a SU-MIMO transmission. In some cases, the two codewords may be received from two TPs. Alternatively, the two codewords may be received in two spatial layers transmitted from a single TP.

Abstract: A method and apparatus are provided for generating and reporting a reference power headroom report (PHR) for New Radio (NR). A user equipment (UE) decides to report a reference power headroom (PH) for at least one carrier frequency in a transmission time interval (TTI). The UE determines at least one of an index (j) of a target received power of a Physical Uplink Shared Channel (PUSCH) to be transmitted in the TTI and a path loss scaling factor, an index (qd) of a reference signal used for measuring path loss for the carrier frequency, or an index (l) of a power control process used for the carrier frequency. The UE then calculates the reference PH based on one or more of the determined at least one index, and reports, in the TTI, a PHR including the reference PH for the carrier frequency.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit and a user equipment (UE) may receive cloned bandwidth part configuration information. In some aspects, the UE may determine a linkage between a primary bandwidth part and the cloned bandwidth part. In some aspects, the BS may transmit and the UE may receive a downlink control information message identifying the primary bandwidth part to signal a bandwidth part switch for the primary bandwidth part and a first bandwidth part or identifying the cloned bandwidth part to signal the bandwidth part switch for the primary bandwidth part and a second bandwidth part. In some aspects, the UE may perform the bandwidth part switch based at least in part on the downlink control information message. Numerous other aspects are provided.
