  • Publication number: 20220141879
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

  • Patent number: 11277332
    Abstract: A user equipment (UE) may identify a bearer (e.g., a default bearer) and request establishment of a second bearer (e.g., a high priority bearer) for use in streaming downlink data from, for example, an application server. The UE may determine a status of a playout buffer and select the first bearer or the second bearer for use in streaming the downlink data associated with the application based on the status of the playout buffer. For example, the first bearer may be used be used by default, and the second bearer may be selected if the amount of data in the playout buffer does not satisfy (e.g., is below) a threshold. In some cases, each bearer may be associated with a transmission control protocol (TCP) port associated with a TCP connection. In some cases, each bearer may be associated with different Internet protocol (IP) address.

  • Patent number: 11197344
    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a transmitting device may identify a Radio Link Control (RLC) service data unit (SDU) to be transmitted to a receiving device. In some cases, the transmitting device may not have access to sufficient resources to transmit the entire RLC SDU. As such, the transmitting device may segment the RLC SDU into RLC SDU segments, and the transmitting device may transmit the RLC SDU segments to the receiving device. If an RLC layer at the receiving device receives one or more RLC SDU segments out of sequence, the RLC layer may initiate a reassembly (or reordering) timer. The RLC layer may reassemble the successfully received RLC SDU segments to be passed to upper layers. Once the timer expires, the RLC layer may declare that the missing RLC SDU segments are lost.
