Abstract: Techniques for wireless communication are described, which may include establishing a connection, by a user equipment (UE), with a first and second evolved NodeB (eNB), wherein each of the eNBs provide radio resources to the UE for respective uplink communications; receiving from the first eNB, at the UE, an indication including an allocation of uplink transmit power between the first eNB and at least the second eNB; and transmitting the uplink communications from the UE to the first and second eNBs based on the indication. The techniques may further include coordinating, by a first eNB, multi-connectivity communication for a UE with at least the first eNB and a second eNB; determining for the UE, at the eNB, an allocation of uplink transmit power between the first eNB and at least the second eNB; and transmitting an indication including the allocation of uplink transmit power allocation from the first eNB to the UE.

Abstract: A method and apparatus for link adaptation in a satellite communication system, wherein a satellite is configured to receive reverse-link (RL) communications from a user terminal (UT) via a service link and retransmit the RL communications to a satellite access network (SAN) via a feeder link. The SAN may select a reference location for the UT within a footprint of the satellite, and determine a set of operating parameters for the RL communications to achieve a target power efficiency of the satellite based on the reference location. The SAN may dynamically adjust one or more of the operating parameters, while maintaining the target power efficiency of the satellite, based at least in part on channel conditions in at least one of the service link, the feeder link, or a combination thereof. Among other advantages, the method disclosed herein may optimize RL communications based on the capabilities of the satellite.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a carrier aggregation (CA) configuration, which may include a large number of component carriers (CCs). Some of the CCs may be designated as basis CCs, and may have a flexible control channel configuration, while other CCs may be designated as supplemental CCs with a restricted control channel configuration. The restricted control channels may have a reduced number of decoding candidates, which may reduce the complexity and increase the likelihood of successfully decoding the control channels. For example, the restricted control channels may be limited to a subset of aggregation levels, a reduced control region, or other restrictions. In some cases, the CCs may be grouped into basis CCs and supplemental CCs based on physical uplink control channel (PUCCH) groups or based on CCs that utilize enhanced physical downlink control channels (ePDCCH).

Abstract: Methods and apparatuses are disclosed for a user terminal (UT) to transmit data to a network controller via a satellite in a satellite system. The UT may begin transmitting, during a time period, a first portion of the data using contention-based resources of the satellite system prior to receiving a grant of scheduled return link resources of the satellite system. The UT may also transmit, on the contention-based resources, a buffer status report (BSR) during the time period. The UT may terminate data transmissions on the contention-based resources after an expiration of the time period or upon receiving the grant of scheduled return link resources. After receiving the grant, the UT may transmit a second portion of the data on the scheduled return link resources.

Abstract: Certain aspects of the present disclosure relate to communicating using multiple connectivity in a wireless network. A device can communicate with first cell served by a first access point over a first connection and with a second cell served by a second access point over a second connection. Moreover, the device can determine whether to perform a half-duplex operation or a full-duplex operation for communicating with the first cell served by the first access point over the first connection. The device can further determine whether to perform a half-duplex operation or a full-duplex operation for communicating with the second cell served by the second access point over the second connection.

A user equipment (UE) may be configured for operation on a plurality of cells. The UE may be configured to periodically report CSI for the plurality of cells and may also report CSI whenever requested. The UE may be configured with a plurality of control channel formats for sending CSI and possibly other control information in different subframes. The plurality of control channel formats may be associated with at least two different capacities. The UE may report CSI for the plurality of cells in the plurality of subframes based on the plurality of control channel formats.

Abstract: Contention-based uplink communications within a wireless communications system are provided in which a user equipment (UE) may transmit data to a base station autonomously, and thereby reduce delay with established procedures for allocating uplink resources to a UE. A base station may allocate contention-based uplink resources from a set of available uplink resources. A UE may determine that data is to be transmitted using contention-based uplink resources, identify available contention-based resources allocated by the base station, and may autonomously transmit the data using the allocated contention-based resources. The contention-based uplink resources may include a subset of available physical uplink shared channel (PUSCH) resources. The contention-based PUSCH resources may include allocated bins, and a UE may select CB-PUSCH resources from one of the bins for transmission of the uplink data.

Abstract: Certain aspects of the present disclosure relate to techniques for aggregating data from a wireless wide area network (WWAN) and wireless local area network (WLAN). In some aspects, a packet convergence entity (e.g., PDCP layer entity) communicates with first and second radio access technology (RAT) links. The packet convergence entity may determine from which of the first and second RAT links a data packet is received and may monitor a sequence number value of each of the received data packets. The packet convergence entity may perform one or more actions based on a determination that one or more packets are missing based on the monitored sequence number values. The packet convergence entity may send a status report in response to one or more events on one or both of the first RAT link and the second RAT link.

Abstract: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.
