Abstract: Methods, systems, and devices for wireless communications are described that provide for power control for dual connectivity. A UE may identify a power control configuration that determines priorities for uplink transmissions over multiple component carriers and one or more base stations. The UE may identify a union of semi-static uplink or flexible transmissions between multiple component carriers employed by one cell group, such as a master cell group and a secondary cell group, and determine a configured power level for the cell group. The UE may then determine whether to transmit an uplink transmission on a cell of another cell group, based on the power control configuration and the configured power level.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for interference management with adaptive resource block (RB) allocation. In an exemplary method, a base station (BS) obtains an indication that downlink transmissions to a first user equipment (UE) potentially interfere with uplink transmissions by a second UE, the BS dynamically allocates, based on the indication, a first set of one or more resource blocks (RBs) for the downlink transmissions to the first UE, and the BS then transmits an indication of the first set of RBs to the first UE. Other aspects, embodiments, and features are also claimed and described.

Abstract: The present disclosure describes various examples of a method, an apparatus, and a computer readable medium for multi-state discontinuous reception (DRX) in wireless communications. For example, one of the methods described may include identifying, by a user equipment (UE), at least two states in connected mode, determining, by the UE, one or more triggers for transitioning between the at least two states, and transitioning, by the UE, from a first state of the at least two states to a second state of the at least two states in response to a determination of the one or more triggers. In an aspect, the transitioning comprises transitioning between cross-slot scheduling and same-slot scheduling, or between a narrow bandwidth and a wide bandwidth, or between a larger periodicity and a smaller periodicity for monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

Abstract: Methods, systems, and devices for configuring physical downlink control channel candidates are described. The method may include monitoring, by a UE, an initial set of physical downlink control channel candidates in a first slot, receiving, by the UE, an indication of an adjusted set of physical downlink control channel candidates to monitor in a second slot based on decoding a physical downlink control channel candidate in the initial set, and monitoring, by the UE in the second slot, the adjusted set of physical downlink control channel candidates. The method may also include adaptively (e.g., autonomously) determining, by the UE, the adjusted set of physical downlink control channel candidates, and corresponding determinations by the base station.

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: Certain aspects of the present disclosure relate to techniques and apparatus for efficient support of connected discontinuous reception (C-DRX) by using a wireless device (e.g., a user equipment (UE)) with a second receiver. A wireless device with two receivers may place one receiver in a low power mode and take the receiver out of the low power mode in response to a signal received from a serving base station (BS) of the wireless device. A BS may direct a wireless device to enter a low power DRX (LP-DRX) mode or enhanced DRX mode having longer low power cycles than a non-enhanced DRX mode, and the wireless device may place a primary receiver in a low power mode in response to the directive from the BS. Other aspects, embodiments, and features are also claimed and disclosed.

Abstract: Various aspects described herein relate to hybrid automatic repeat/request (HARQ) communications in a wireless network. A first instance of a HARQ communication is transmitted or received over a first set of one or more links. Based on the transmitting or receiving the first instance of the HARQ communication, a scheduling grant can be received for a second instance of the HARQ communication over a second set of one or more links different from the first set of one or more links. The second instance of the HARQ communication can accordingly be transmitted or received over the second set of one or more links based at least in part on the scheduling grant.

Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The method may be performed by a subordinate entity. The subordinate entity receives a transmission from the scheduling entity in a data portion of the subframe. The subordinate entity processes, in the subframe, at least a part of the transmission. The subordinate entity then determines whether to send an acknowledgment (ACK) signal for the transmission, the ACK signal to be transmitted in an ACK portion of the subframe before a remaining part of the transmission is processed, and sends the ACK signal to the scheduling entity in the ACK portion of the subframe based on the determination. The data portion and the ACK portion are contained in the subframe.

Abstract: Certain aspects of the present disclosure generally relate to techniques for on-demand paging. In one aspect, a method is provided for receiving a paging message by a mobile device. The method generally includes acquiring network time, determining, based on the network time or an internal timer, that the mobile device is within a paging window wherein the mobile device can receive a paging message, and sending an indication message, in response to the determination. The mobile device may receive a response to the indication message, the response indicating whether or not there is a paging message for the mobile device.
