Abstract:
Methods, systems, and devices for wireless communication are described. A base station may transmit a configuration for enhanced paging to a UE being served by a cell over a shared frequency band. The enhanced paging may include multiple paging intervals for each paging cycle. The UE may enable reception for a paging interval and determine whether the UE receives a downlink transmission. The UE may lengthen a paging interval or enable reception during a second paging interval based in part on determining whether the UE receives a downlink transmission. In some examples, the UE may receive a paging queue status indication indicating that paging information will be transmitted during a paging interval or a later interval, or indicating that no paging information is present at a serving cell.

Abstract:
In a communication system, user equipment (UE) conditionally performs uplink transmit diversity (ULTD) either by Switched Antenna Transmit Diversity (SATD) or Beamforming Transmit Diversity (BFTD) using a first antenna and a second antenna. Either a serving node or the UE determines that uplink transmit diversity is conditionally authorized. Either a serving node or the UE measures a value. The UE transmits using ULTD in response to determining that an enabling condition based on the value is satisfied. The UE can also disable uplink transmit diversity in response to determining that a disabling condition based on the value is satisfied. The disabling condition comprises a disabling threshold that equals the enabling condition comprising an enabling threshold with a threshold adjustment for hysteresis.
Abstract:
Various aspects related to techniques for harmonization between common reference signal (CRS) and demodulation reference signal (DM-RS) based transmission modes (TMs) in unlicensed spectrum are described. In one aspect, a downlink/uplink (DL/UL) subframe configuration may be signaled for each subframe. Information provided by the DL/UL subframe configuration may indicate whether the respective downlink subframe is a single-frequency network (MBSFN) subframe (associated with DM-RS-based TM) or a non-MBSFN subframe (associated with CRS-based TM). In another aspect, periodic as well as aperiodic channel state information (CSI) reporting requests may be supported. In yet another aspect, discontinued reception (DRX) wake ups for unlicensed carriers may be explicitly or implicitly indicated to a user equipment (UE) via a carrier in a licensed spectrum.
