Abstract: A method for extending the connection time of talkgroup radios in a talkgroup conversation based on historical talkgroup statistics is provided. A talkgroup conversation request intended for a talkgroup is received from a first mobile unit. A group call grant message is sent to radios that are members of the talkgroup. The group call grant message initiates the talkgroup conversation with a first talkgroup call and includes an extended connection time value. Once it is determined that the first talkgroup call has ended, all radios that are members of the talkgroup are kept in a connected state. An extended connection timer utilizing the extended connection time value is started. Upon expiration of the extended connection timer, all radios that are members of the talkgroup are set to an idle state.

Abstract: Methods, systems, and devices for wireless communications are described which may enable a user equipment (UE) and a base station to use outer-loop feedback support to reach a desired error rate for low latency communications. For example, a base station may transmit a proxy acknowledgement feedback configuration to a UE for communications associated with a low target error rate. In some cases, after receiving the communications from the base station, the UE may receive secondary communications from the base station. The UE may then decode the first and/or second communications according to the proxy acknowledgement feedback configuration and/or a normal acknowledgement feedback configuration and may determine a proxy acknowledgement feedback based on the decoding. Further, the UE may transmit the proxy and/or normal acknowledgement feedback to the base station, which may update outer-loop power settings for the low latency communications based on the acknowledgement feedback.
