Abstract:
1. A method for wireless communications comprising: determining, by a network device, an operational mode and an operational state of a Robust Header Compression (ROHC) compressor or a ROHC decompressor; and changing, by the network device, a semi-persistent scheduling (SPS) mode of a radio bearer in response to a change in the operational state of the ROHC compressor or ROHC decompressor, wherein determining the operational mode and the operational state comprises determining a transition between different operational states associated with the ROHC compressor, and changing the SPS mode comprises activating uplink semi-persistent scheduling when the operational state of the ROHC compressor changes from a first-order state to a second-order state and deactivating the uplink semi-persistent scheduling when the operational state of the ROHC compressor exits the second-order state.
