Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a first carrier associated with a first radio access technology, at least a first uplink grant from a base station. The UE may implement one or more backoff schemes. For example, the UE may transmit, using resources indicated by at least the first uplink grant, an uplink message based on a temperature of one or more components of the UE satisfying a threshold, the uplink message including a transport block (TB) indicating data, a buffer status report (BSR) associated with the data, one or more padding bytes different from the data, or any combination thereof. The UE may monitor for at least a second uplink grant from the base station during a first time period based on transmitting the uplink message.

Abstract: Certain aspects of the present disclosure provide techniques for sending uplink control information. A method that may be performed by a user equipment (UE) includes receiving an uplink grant for transmission on a plurality of physical uplink shared channels (PUSCHs), the plurality of PUSCHs being located on different component carriers (CCs); identifying one or more PUSCHs of the plurality of PUSCHs on which uplink control information (UCI) can be transmitted in a slot; assigning PUSCH data to the one or more identified PUSCHs on which the UCI can be transmitted before assigning PUSCH data to remaining PUSCHs of the plurality of PUSCHs; and transmitting the UCI and the PUSCH data in the slot on the assigned PUSCHs.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving buffer size setting for one or more buffer status reports, such as one or more extended buffer status reports (eBSRs) in a wireless communication system. According to certain aspects, a method is provided herein for wireless communications performed by a user equipment (UE). The method generally includes determining a first amount of data stored in a buffer at the UE; and if the first amount of the data satisfies (e.g., is equal to or greater than) a threshold, sending a first BSR indicating a second amount of buffered data at the UE greater than the first amount. As a result, the UE may be scheduled by the base station for a greater amount uplink resources for transmitting the buffered data.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration. The UE may transmit, via a scheduling request resource of a second logical channel that has a valid scheduling request configuration, a scheduling request for resources to transmit the data buffered for transmission via the first logical channel. Numerous other aspects are described.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving a number of uplink grants from a base station. The method further includes estimating a payload size for data to be transmitted from a UE buffer for a number of logical channels. The payload size corresponds to a sum of a number of data bytes to be transmitted and an amount of overhead bytes to be transmitted. The method still further includes determining a subset of the number of uplink grants to use for uplink transmission based on reducing a total padding size associated with transmitting the payload size, for each combination of the number of uplink grants. The method also includes transmitting the data from the UE buffer within a number of transport blocks, to the base station. The number of transport blocks corresponds to the subset of the number of uplink grants.

Abstract: A method and apparatus for receiving a notification of missing packets include receiving a set of data packets transmitted by a device and having a corresponding set of sequence numbers, identifying one or more data packets having corresponding sequence numbers that fall within the set of sequence numbers and are yet to be received, receiving an indication from the device that the one or more data packets will not be transmitted by the device, and processing the set of data packets without the one or more data packets in response to receiving the indication.

Abstract: Methods, systems, and devices for wireless communication are described. The method may include receiving an UL grant for each CC of a plurality of CCs. In an aspect, each UL grant may include a number of transport blocks (TBs) assigned to each CC. The method may further include sorting CCs among the plurality of CCs as a function at least in part based on the number of TB for each of the CCs, and transmitting one or more packet data units (PDUs) using a subset of CCs of the plurality of CCs. In an aspect, the subset of CCs may be based at least in part on the sorting, and any CC of the plurality of CCs in which only medium access control (MAC) padding PDUs would be transmitted may not be included in the subset of CCs.

Abstract: Aspects described herein relate to wireless communications. Protocol data units (PDUs) can be received at a network layer from one or more transmitting nodes using a link associated with each respective transmitting node. One or more missing PDUs can be detected based, at least in part, on sequence numbers of the received PDUs. A timer can be started based on the detection of the one or more missing PDUs. In response to expiration of the timer, and without receiving the one or more missing PDUs before the expiration of the timer, a lower network layer can be notified that the one or more missing PDUs are received to prevent attempted transmitting/retransmitting or other processing of the one or more missing PDUs.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for quick radio link control (RLC) retransmission on hybrid automatic repeat request (HARQ) failure during tune away. According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.

Abstract: Aspects of the present disclosure provide methods, systems, devices and/or apparatuses for logical channel prioritization by a user equipment (UE) within a Long Term Evolution (LTE) wireless communications network. The UE may have multiple logical channels each associated with one or more applications or services of the UE. The UE may identify whether a quality of service (QoS) obligation to allocate at least a portion of uplink resources to a logical channel for a time period is present, and may also identify whether the logical channel has control data to be transmitted from the UE. If a QoS obligation and/or control data are present for the logical channel, the UE may allocate at least a portion of the uplink resources to the logical channel.
