Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a receiving device, such as a user equipment (UE), may reduce packet congestion associated with communications between the receiving device and a transmitting device, such as a server, via a radio access network (RAN). The receiving device may measure congestion metrics associated with receiving data packets from the transmitting device via the RAN. The congestion metrics may include RAN congestion metrics and transport or application layer congestion metrics associated with the network connection between the receiving device and the transmitting device. The receiving device may estimate packet congestion at the receiving device according to the measured congestion metrics. The receiving device may modify connection parameters of the network connection based on the estimated packet congestion. The receiving device may communicate with the transmitting device over the network connection in accordance with the modified connection parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that uplink data is available for transmission at the UE prior to a scheduling request occasion. The UE may skip transmission of a scheduling request during the scheduling request occasion based on identifying that an uplink grant is pending. The UE may transmit at least a portion of the uplink data to a base station using a resource allocation indicated by the uplink grant. Alternatively, the UE may transmit the scheduling request to the base station during a first scheduling request occasion. The UE may initiate a retransmission timer based on transmitting the scheduling request. Accordingly, the UE may skip retransmission of the scheduling request during a second scheduling request occasion that is subsequent to the first scheduling request occasion based on the retransmission timer.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a grant delay request to a base station. The grant delay request may indicate a future time, at or thereafter a base station is requested to allocate resources to the UE. The base station may transmit the uplink grant to the UE allocating the resources to the UE based on the grant delay request, and the UE may transmit, to the base station, an uplink transmission including the uplink data based on the uplink grant. The UE may transmit the grant delay request as part of a scheduling request (SR), or as part of a buffer status report (BSR), or a combination of these.

Abstract: A user equipment (UE) may be configured with one or more queues at which packets are accumulated before being transferred between at least one higher layer and at least one lower layer. The UE may release packets from the one or more queues based on at least one set of parameters. The UE may determine one or more radio conditions associated with at least one traffic flow between the UE and a network. The UE may configure a set of parameters associated with transfer of packets for the at least one traffic flow between a lower layer of the UE and a higher layer of the UE based on the one or more radio conditions. The UE may communicate a first set of packets with the network for the at least one traffic flow based on the set of parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a trigger for transmitting a buffer status report (BSR). The UE may transmit, to a base station, a long BSR for a single logical channel group (LCG) with data to be transmitted based at least in part on at least one of a determination that a current buffer size for the single LCG is greater than a maximum buffer size indication in a short BSR or a determination that a current achievable uplink throughput using the short BSR is less than a configured uplink throughput. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a method may include simulating a degradation of at least one of a first wireless communication link with a network or a different second wireless communication link with the network based on detecting that a first set of one or more packets, which were received via the first wireless communication link with the network and were added to a packet buffer, and a second set of one or more packets, which were received via the different second wireless communication link with the network and were added to the packet buffer, satisfy a threshold occupancy of the packet buffer. Numerous other aspects are provided.

Abstract: Techniques for wireless communications are described. Control information used to preschedule communication resources may be received and communications may be performed based on the control information using a prescheduling technique. A scheduling type used for the control information may be determined using configuration information, an indication included in the control information, or both. A wireless device that is prescheduled communication resources may not start or not restart an inactivity timer based on the received control information. Also, a wireless device that is prescheduled communication resources may not start a retransmission timer based on the received control information. Additionally, a wireless device that is prescheduled communication resources may also refrain from transmitting a scheduling request based on a duration until a next instance of prescheduled communication resources is expected to occur.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications networks, a device, such as a user equipment (UE), may be configured to detect a signal blockage affecting one or more antennas of the UE. The signal blockage may be associated with the position of a body, such as a user, relative to the one or more antennas of the UE, which may include how a user places their hand on or near the device during use. The position of the body may block one or more of the antennas of the UE, causing increased signal attenuation and decreased communications performance. The UE may be configured to signal, an indication based on detecting the signal blockage.

Abstract: Techniques for sending packets and maintaining synchronization during handover is described. A user equipment (UE) may be handed over from a source base station to a target base station. The source base station may forward packets for the UE to the target base station, which may receive the packets out of order. In one design, the target base station may determine whether each packet can be sent in order to the UE, send the packet if it can be sent in order, and discard the packet otherwise. In another design, the target base station may re-order packets received within a re-ordering window and may send the re-ordered packets to the UE. In yet another design, the target base station may process each packet received out of order as if the packet is in order, e.g., by incrementing a hyper-frame number (HFN) or re-assigning the packet with a later sequence number.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.
