Abstract

Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a method, apparatus, system, computer program product, non-transitory computer-readable medium, user equipment, transmitter device, and wireless communication device are presented for unidirectional robust header compression (RoHC). The transmitter device may identify a system resource condition of at least one of the transmitter device or a receiver device of one or more data units, configure robust header compression in a single direction for wireless communication of the one or more data units between the transmitter device and the receiver device, and/or process the data units based at least in part on configuring the robust header compression. Numerous other aspects are provided.

configuring unidirectional robust header compression in a single direction and not another direction, based on the system resource condition of at least one of the transmitter device or the receiver device, for wireless communication of the one or more data units between the transmitter device and the receiver device,
wherein configuring the unidirectional robust header compression in the single direction includes:
determining to compress packets of Transmission Control Protocol (TCP) acknowledgment (ACK) packet type in the single direction and not to compress TCP data packets in the single direction based on the processor cycle availability value satisfying a threshold value; and
updating the unidirectional robust header compression to compress TCP ACK packets in the single direction, based on determining to compress packets of the TCP ACK packet type, and not to compress TCP data packets in the single direction;

processing the one or more data units based at least in part on configuring the unidirectional robust header compression; and
transmitting the one or more processed data units to the receiver device.

2. The method of claim 1 , wherein processing the one or more data units includes compressing a subset of the one or more data units.

3. The method of claim 2 , further comprising transmitting a message indicating the subset of the one or more data units.

4. The method of claim 2 , wherein compressing the subset of the one or more data units includes compressing the subset of the one or more data units to be transmitted based at least in part on a token based mechanism.

5. The method of claim 1 , wherein configuring the unidirectional robust header compression in the single direction for wireless communication of the one or more data units between the transmitter device and the receiver device includes configuring the unidirectional robust header compression in the single direction based at least in part on a message received over an air interface.

6. The method of claim 1 , wherein the system resource condition is further based at least in part on at least one of:
an amount of available memory,
a bus bandwidth availability, or
a combination thereof.

7. The method of claim 1 , wherein processing the one or more data units includes compressing a portion of a data unit of the one or more data units.

8. The method of claim 1 , wherein configuring the unidirectional robust header compression in the single direction includes:
ceasing compression of handover/reestablishment acknowledgment mode (AM) packet data convergence protocol (PDCP) retransmission packet data units (PDUs) based on the system resource condition.
