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: 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: 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: Methods, systems, and devices are described for wireless communication. A user equipment (UE), for example, may determine a content size of an uncompressed buffer and a content size of a compressed buffer. The UE may then generate a buffer status report (BSR) based on the content sizes of the uncompressed buffer and the compressed buffer. Alternatively, a base station may receive a BSR based on a size of an uncompressed buffer of the UE. The base station may then receive a compressed packet from the UE and may determine a compression gain based on a size of the compressed packet and a size of a corresponding uncompressed packet. The base station may then adjust the received BSR based on the compression gain.

Abstract: Techniques are described for wireless communication. One method includes receiving, at a medium access control (MAC) entity, protocol data units (PDUs) corresponding to one or more Internet protocol (IP) flows, routing the PDUs from the MAC entity to respective radio link control (RLC) entities based on a logical channel prioritization, and forwarding the PDUs from respective RLC entities to one or more packet data convergence protocol (PDCP) entities mapped to each RLC entity. Another method includes receiving, at a protocol layer entity above an RLC layer of a transmitting device, a PDU, labeling the PDU with a unique PDCP instance identifier packet, and passing the PDU to a protocol layer entity below the PDCP layer of the transmitting device.

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: Methods, systems, and devices are described for improving discontinuous reception (DRX) periods using enhanced physical HARQ indicator channel (PHICH) decoding. A user equipment (UE) may determine that an uplink (UL) retransmission (ReTx) is unnecessary based on the content of the original UL transmission. For example, the transmission may include media access control (MAC) layer padding rather than relevant application layer data. The UE may then identify a DRX sleep period that includes the subframe where the ReTx would take place. In some cases, the DRX sleep period may include a subframe where the UE would otherwise receive an acknowledgement message (AM) from a base station. The UE may then enter a DRX sleep state. In another example, the DRX sleep period is based on the content of a received AM. If the UE receives an ACK, the UL ReTx may be unnecessary.

Abstract translation: 描述了使用增强的物理HARQ指示符信道（PHICH）解码来改善不连续接收（DRX）周期的方法，系统和设备。 用户设备（UE）可以基于原始UL传输的内容来确定不需要上行链路（UL）重传（ReTx）。 例如，传输可以包括媒体访问控制（MAC）层填充而不是相关的应用层数据。 然后，UE可以识别包括将发生ReTx的子帧的DRX休眠周期。 在一些情况下，DRX休眠期可以包括UE将否则从基站接收确认消息（AM）的子帧。 然后，UE可以进入DRX睡眠状态。 在另一示例中，DRX休眠期基于所接收的AM的内容。 如果UE接收到ACK，那么UL ReTx可能是不必要的。
