CONFIGURATION OF PACKET LOSS RATE (PLR) BASED ADAPTATION
Disclosed are methods, systems, apparatus, and computer programs for configuring packet loss rate (PLR) thresholds for UEs in a wireless communications network. In one aspect, a method includes receiving, by a UE connected to a wireless communications network, a packet loss rate (PLR) threshold configuration message from a node in the wireless communications network; determining, by the UE and based on the PLR threshold configuration message, a new PLR threshold configuration; and in response to determining the new PLR threshold configuration, selectively adjusting one or more configuration settings associated with a connection to the wireless communications network based on the new PLR threshold configuration.
1 . A method comprising:
receiving, from a first user equipment (UE) that supports coverage and handover enhancements using multimedia error robustness (CHEM), a maximum packet loss rate (PLR) value adaptively determined for an end-to-end communication between the first UE and a second UE;
distributing the maximum PLR value between an uplink maximum PLR value and a downlink maximum PLR value; and
transmitting the uplink maximum PLR value and the downlink maximum PLR value to a base station serving the first UE.
2 . The method of claim 1 , further comprising: causing the base station to determine one or more handover thresholds.
3 . The method of claim 1 , wherein the maximum PLR value indicates a robustness of a codec.
4 . The method of claim 1 , wherein receiving the maximum PLR value comprises: obtaining a session description protocol (SDP) parameter from the first UE, wherein the SDP parameter comprises the maximum PLR value.
5 . The method of claim 1 , wherein the maximum PLR value is adaptively determined with application layer redundancy.
6 . The method of claim 1 , wherein the maximum PLR value is adaptively determined with jitter buffer management (JBM).
7 . The method of claim 1 , wherein the maximum PLR value is adaptively determined with packet loss concealment (PLC).
8 . A network entity comprising a processor configured to cause the network entity to perform operations comprising:
receiving, from a first user equipment (UE) that supports coverage and handover enhancements using multimedia error robustness (CHEM), a maximum packet loss rate (PLR) value adaptively determined for an end-to-end communication between the first UE and a second UE;
distributing the maximum PLR value between an uplink maximum PLR value and a downlink maximum PLR value; and
transmitting the uplink maximum PLR value and the downlink maximum PLR value to a base station serving the first UE.
9 . The network entity of claim 8 , wherein the network entity comprises a policy and charging rules function (PCRF).
10 . The network entity of claim 8 , the operations further comprising: causing, via the transmitted uplink maximum PLR value and the downlink maximum PLR value, the base station to determine one or more handover thresholds.
11 . The network entity of claim 8 , wherein the maximum PLR value indicates a robustness of a codec.
12 . The network entity of claim 8 , wherein receiving the maximum PLR value comprises: obtaining a session description protocol (SDP) parameter from the first UE, and wherein the SDP parameter comprises the maximum PLR value.
13 . The network entity of claim 8 , wherein the maximum PLR value is adaptively determined with application layer redundancy.
14 . The network entity of claim 8 , wherein the maximum PLR value is adaptively determined with jitter buffer management (JBM).
15 . The network entity of claim 8 , wherein the maximum PLR value is adaptively determined with packet loss concealment (PLC).
16 . A user equipment (UE) that supports coverage and handover enhancements using multimedia error robustness (CHEM), the UE comprising a processor configured to perform operations comprising:
adaptively determining a maximum packet loss rate (PLR) value for an end-to-end communication with a second UE; and
causing the UE to transmit the maximum PLR value to a network entity, wherein the network entity distributes the maximum PLR value between an uplink maximum PLR value and a downlink maximum PLR value, and wherein the network entity transmits the uplink maximum PLR value and the downlink maximum PLR value to the base station.
17 . The UE of claim 16 , wherein the maximum PLR value indicates a robustness of a codec.
18 . The UE of claim 16 , wherein:
the processor is configured to cause the UE to transmit a session description protocol (SDP) parameter to the network entity, and
the SDP parameter comprises the maximum PLR value.
19 . The UE of claim 16 , wherein the processor is configured to cause the UE to adaptively determine the maximum PLR value with the second UE based on application layer redundancy.
20 . The UE of claim 16 , wherein the processor is configured to cause the UE to adaptively determine the maximum PLR value with the second UE based on at least one of:
jitter buffer management (JBM), or
packet loss concealment (PLC).
