Abstract: The apparatus improves HD-FDD data transmission rates, e.g., for eMTC by using a self subframe scheduling PDSCH that overlaps a M-PDCCH transmission in time. The apparatus may communicate using ACK(s)/NACK(s) for multiple HARQs that are bundled and/or multiplexed within a subframe in order to increase a number of HARQs.

Abstract: Various aspects described herein relate to communicating using a configurable bandwidth. A user equipment (UE) can receive a control channel from a serving evolved Node B (eNB), where the control channel includes a resource grant for an uplink shared data channel including a number of resource block groups starting from a starting resource block group in an allocation space, and where the allocation space includes a plurality of resource block groups in a frequency domain over a plurality of symbols in a time domain. The UE can transmit data in the uplink shared data channel starting from the starting resource block group in the allocation space and continuing through the number of resource block groups in the allocation space over the frequency domain first and over the time domain second.

Abstract: Techniques for sending control information to support operation on multiple component carriers (CCs) are disclosed. A user equipment (UE) may be configured with multiple CCs for carrier aggregation. The multiple CCs may be associated with different uplink-downlink configurations and may have different downlink subframes and uplink subframes. In one aspect, uplink control information (UCI) for a secondary CC (SCC) may be sent on a primary CC (PCC) based on a UCI transmission timeline for the PCC (and not based on a UCI transmission timeline for the SCC). For example, a downlink grant for the SCC may be sent based on a downlink grant transmission timeline for the PCC. In another aspect, uplink grants for an SCC may be sent on the PCC based on an uplink grant transmission timeline for the PCC (and not based on an uplink grant transmission timeline for the SCC).

Abstract: Provided is a method of wireless communication which includes selecting a codebook from a plurality of codebooks in accordance with an antenna characteristic, and transmitting an indication of the selected codebook. Each of the plurality of codebooks is associated with one of a plurality of antenna characteristics. In some designs, channel state information is received from a user equipment. The channel state information may be used to determine downlink scheduling and/or precoding. In some designs, the channel state information may include feedback elements associated with different subband granularity. The feedback elements may also indicate a selection of a subset of precoder column vectors and/or a phase offset between two groups of transmit antennas.

Abstract: Methods, apparatuses, and computer program products are disclosed for facilitating indicating and detecting control region sizes. A multi-carrier communication between a wireless terminal and a base station is facilitated by a first carrier having a first control region size and a second carrier having a second control region size. Embodiments are disclosed in which control region sizes are ascertained from a control signal, wherein the control is generated by either scrambling an aspect of the control signal based on the second control region size, or relating the second control region size with the first control region size. Other disclosed embodiments for ascertaining control region sizes include a reverse interleaver embodiment, wherein a set of modulation symbols is mapped beginning from a last data symbol and ending with a first available data symbol.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may transmit UE capability information indicating support for multiple sounding reference signal (SRS) port adaptation patterns to a network entity. Each SRS port adaptation pattern defines a series of SRS transmissions and indicates whether each SRS transmission is a single-port SRS transmission or a multi-port SRS transmission. The UE may receive, from the network entity, a configuration of the multiple SRS port adaptation patterns based on the UE capability information, UE traffic, etc. The UE may dynamically select and/or switch an SRS port adaptation pattern per time slot for sending SRS transmissions.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives, from a location server, a positioning reference signal (PRS) configuration indicating one or more PRS resources to be measured by the UE, transmits, to a base station serving the UE, measurement report payload related information based on the PRS configuration, obtains positioning measurements of the one or more PRS resources, transmits a scheduling request (SR) to the base station, the SR requesting an uplink grant for a measurement report for the positioning measurements, receives the uplink grant from the base station in response to the SR, the uplink grant indicating uplink resources on which to transmit the measurement report, and transmits at least a portion of the measurement report to the base station on the uplink resources indicated by the uplink grant.
