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: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus of a first cell communicates with a second cell in relation to a coordinated multipoint (CoMP) transmission of control information by the second cell and data by the first cell to a user equipment (UE) in a range expanded region of the first cell, determines a desired transmission power level for an uplink transmission to the first cell by the UE, and provides the desired transmission power level for the uplink transmission to the second cell.

Abstract: Various aspects relate generally to dynamic uplink carrier selection for uplink control information (UCI) multiplexing. A user equipment may signal uplink carrier selection information to support informed carrier selection while decreasing the occurrence of switching gaps associated with signalling the uplink carrier selection information. The UE may transmit, on one carrier, uplink carrier quality indications associated with multiple carriers. The UE may receive a dynamic carrier selection indication and multiplex UCI on the selected carriers.

Abstract: Extension of power efficient paging in a wireless network. In some examples, information is buffered for a time period corresponding to a paging slot, or both the paging slot and at least one adjacent slot. The buffered control information is processed to detect paging downlink control information (DCI) and a tracking reference signal (TRS). Based on the processing, the paging message is scheduled in a physical downlink shared channel (PDSCH) in the paging slot. In some examples, quasi-co-located (QCL) processing may be performed on the TRS and the paging DCI paging message, and a paging message is scheduled, based on the QCL processing, in a physical downlink shared channel (PDSCH) in a same or offset paging slot.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to indicate to a base station a distribution of transmit antennas and receive antennas across a set of antenna panels, and the base station may configure resource sets for reference signal transmissions from the antenna panels based on the indicated distribution. In a first example, the UE may be configured to indicate a respective number of transmit antennas and receive antennas at each antenna panel. In a second example, the UE may be configured to indicate a sum of transmit antennas and a sum of receive antennas across all antenna panels, along with information on how the transmit antennas and receive antennas are distributed. Based on the indication, the base station may configure resource sets for reference signal transmission on sets of ports in resources of the resource sets.
