Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may receive, from a base station, a first sidelink grant for a transmission between the first UE and the second UE. The first UE may communicate the transmission according to the sidelink grant. The first UE may monitor a configured duration of a sidelink round trip time timer from the transmission. The first UE may monitor a configured duration of a sidelink retransmission timer from an end of the sidelink round trip time timer. The first UE may allow start of a discontinuous reception (DRX) mode after the duration of the sidelink retransmission time if a second grant is not received during the sidelink retransmission timer.

Abstract: Various aspects of the present disclosure generally relate to reassembly of service data units (SDUs) for radio link control (RLC) duplication. In some aspects, a receiving device may receive, via a first RLC entity, one or more first protocol data units (PDUs) encapsulating a first portion of an SDU. The receiving device may receive, via a second RLC entity, one or more second PDUs encapsulating a second portion of the SDU, where the second PDUs are associated with duplication of the one or more first PDUs. The receiving device may assemble, based at least in part on a determination that neither the first portion nor the second portion is a complete version of the SDU, a combined SDU from the first portion and the second portion. Numerous other aspects are provided.

Abstract: A method, an apparatus, and a computer readable-medium for wireless communication are provided. The apparatus receives data via a first group of component carriers (CCs) of a plurality of groups of aggregated CCs. The first group of CCs correspond to unlicensed or shared frequencies. The apparatus selects a CC from at least two CCs of the first group of CCs for transmission on a physical uplink control channel (PUCCH). The selection of the CC is based on at least an uplink-transmission clearance status of each of the at least two CCs. The apparatus transmits the PUCCH via the selected CC.

Abstract: Methods, systems, and devices are described for wireless communication employing two-stage control channel messaging. Systems, methods, and apparatuses for two stage two-stage physical downlink control channel (PDCCH) with a downlink control information (DCI) flag and DCI format size indicator are described. For instance, the present disclosure presents an example method of wireless communication at a wireless device, which may include receiving, at a first bandwidth and during a transmission time interval (TTI), a first control channel message. In addition, the example method may include determining, based on a flag in the first control channel message, whether a second control channel message is present in the TTI. Furthermore, the example method may include receiving, at a second bandwidth, the second control channel message where the flag indicates that the second control channel message is present for the TTI.

Abstract: Various aspects described herein relate to communicating a scheduling request (SR) in a wireless network. A frame structure that allows dynamic switching of transmission time intervals (TTI) between uplink and downlink communications may be used to communicate with a network entity. At least one SR mode can be selected for SR transmission to the network entity in one or more of the TTIs configured for uplink communications based at least in part on the frame structure. The SR can be transmitted to the network entity in at least one uplink TTI of the one or more TTIs configured for uplink communications based at least in part on the at least one SR mode.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with specifying a traffic-to-pilot (T/P) ratio per subframe and/or resource block to allow a base station to transmit over the subframes and/or resource blocks using varying transmit powers. In one example, a device communicating with the base station can receive a plurality of T/P ratios each related to a power used by the base station to transmit over one of a plurality of carriers in a specific subframe or resource block, determine a power of a reference signal received from the base station over a carrier of the plurality of carriers, and process a data signal received over the carrier within the specific subframe or resource block based in part on applying, to the power of the reference signal, a T/P ratio of the plurality of T/P ratios corresponding to the carrier.

Abstract: Certain aspects of the present disclosure relate to reporting power headroom in wireless communications. A device can establish a first connection served by at least a first cell, and establish a second connection served by at least a second cell in multiple connectivity/carrier aggregation. The device can then determine to report a first power headroom in a first uplink subframe of the first cell in the first cell. The device can also determine a reporting configuration for possibly reporting a second power headroom based on a second subframe of the second cell as a companion report with the first power headroom when a type of the second subframe of the second cell is not an uplink subframe.

Abstract: Certain aspects of the present disclosure relate to procedures for aggregation in dual connectivity. In one aspect, a wireless device may receive configuration information to communicate with a first network entity (e.g., master eNodeB) through a first primary cell (PCell) of a corresponding group of cells of the first network entity, and with a second network entity (e.g., secondary eNodeB) through a second primary cell (PCellSCG) of a corresponding group of cells of the second network entity. The second network entity may be non-collocated with the first network entity. The wireless device may include an information convergence entity (e.g., PDCP entity) that aggregates the configuration information from the first and second network entities when the wireless device is in communication with both entities. In another aspect, the second network entity may have one of the cells in the corresponding group of cells operate as the second primary cell.
