    Abstract: Aspects relate to obtaining, at a first scheduled entity, a first priority ranking of first uplink (UL) data scheduled for transmission to a scheduling entity and a first data scheduled for transmission to a second scheduled data, as well as a second priority ranking of second data scheduled for transmission to a third and fourth scheduled entity, respectively. The scheduling uses at least a portion of a sidelink resource reserved for sidelink communication for the transmissions. The scheduling of the transmissions using at least the portion of the sidelink resource are based on the first priority ranking and the second priority ranking. Various transmission cancellation and reception preemptions are transmitted from transmitting scheduled entities to other transmitting or receiving scheduled entities, respectively. Such cancellations and preemptions are based on the priority rankings, prediction of data transmission collisions and prediction of interference at receiving entities.

    Abstract: Methods and apparatus for efficient transmission of data by half-duplex transceivers in satellite communication systems are provided. Time reference for the return link is skewed or time-lagged relative to the time reference for the forward link to reduce the amount of guard time required to separate return link transmission from forward link reception by the half-duplex transceiver of a user terminal. The guard time is determined based on a maximum differential round-trip propagation delay and transition times of the half-duplexer transceiver to switch between transmit and receive modes. In a satellite communication system in which a large number of active user terminals are present in a beam coverage, random time offsets are applied to spread approximately equal traffic loads across the time offsets.

    Abstract: Methods, systems, and devices are described for wireless communication. A base station may configure a set of timing adjustment groups (TAGs) and a set of PUCCH cell groups for a user equipment (UE). The serving cells in the TAGs may be associated with different PUCCH cell groups. The UE may initiate a time alignment timer for each TAG, and if the timer expires prior to receiving a timing adjustment command, the UE may initiate a timing alignment procedure for a subset of serving cells based on the association between the TAGs and the PUCCH cell groups.

    Abstract: Enhanced carrier aggregation may require development of mechanisms to enable carrier aggregation for an increased number of component carriers. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for wireless communication are provided. The apparatus may be a user equipment. The apparatus may receive, with an uplink grant, a request for channel state information. The apparatus determines the number of bits comprising the request. The determined number of bits may be based on or associated with the number of serving cells configured for the apparatus. The apparatus reports the channel state information in response to the request based on information in the determined number of bits.

    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 the data packets are received out of order. For example, the packet convergence entity may deliver the data packets to an upper layer entity as they are received (e.g., in order or out of order), may reorder the data packets and ignore data packet losses, and/or may request retransmissions of missing data packets.
