Activating and deactivating semi-persistent scheduling for an LTE VoIP radio bearer

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines an operational state of a header compressor or a header decompressor by determining a transition between different operational states associated with the header compressor and/or by determining a transition between different operational states associated with the header decompressor. A persistent scheduling mode is changed in response to a change in the operational state of the header compressor. The persistent scheduling mode may be changed by activating uplink persistent scheduling when the operational state of the header compressor changes from a first order state to a second order state, and/or by deactivating the uplink persistent scheduling when the operational state of the header compressor exits the second order state.

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.
