摘要： 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.

摘要： 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.

摘要： 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.

摘要： Techniques and apparatus for implementing a radio link control (RLC) layer and/or packet data convergence protocol (PDCP) layer window advance with holes (e.g., one or more missing packets) are provided. One technique includes generating a sequence of packets for transmission to an apparatus. A determination of whether to request the apparatus to at least temporarily ignore missing packets from the sequence is made based on one or more criteria. A message with an indication of the determination is transmitted to the apparatus. The apparatus may receive the sequence of packets, detect missing packets in the sequence, and process the sequence of packets in accordance with the indication in the received message.

摘要： 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.

For example, certain aspects relate to a technique for receiving first timing advance information associated with uplink wireless communications with a base station (BS), transmitting a random access connection request message to the BS, receiving a random access response from the BS while the first timing advance information is within a valid time period, the random access response comprising second timing advance information associated with uplink wireless communications with the base station, determining, after receiving the random access response, that the valid time period for the first timing advance information has expired, and utilizing the second timing advance information for uplink communications with the BS after determining that the valid time period for the first timing advance information has expired. Numerous other aspects are provided.

摘要： 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.

摘要： The present disclosure relates to pseudo-randomization of unused resources at a medium access control layer (MAC) of a user equipment (UE). For example, the disclosure presents a method and an apparatus for determining that an uplink (UL) resource grant, associated with a first radio access technology (RAT), for the UE results in unused resources where there are a greater number of resources than available data for transmission at the UE, wherein the UE is configured to receive information associated with a second RAT, and wherein the first RAT is different from the second RAT, populating the unused resources, at a medium access control (MAC) layer, with pseudo-randomized bits, and transmitting at least a portion of the available data and the populated unused resources using the UL resource grant associated with the first RAT. As such, pseudo-randomization of unused resources at a medium access control layer (MAC) of a UE may be achieved.
