Abstract
A base station distributed unit receives, from a wireless device in a radio resource control (RRC) non-connected state, one or more transport blocks via a periodic resource. The base station distributed unit determines an absence of communication with the wireless device. The base station distributed unit sends, to a base station central unit, one or more messages indicating release of the periodic resource based on the absence of communication.
Claims20
A method comprising:
- sending, by a base station distributed unit to a base station central unit, a wireless device context comprising a configuration of a periodic resource of a wireless device;
- receiving, by the base station distributed unit from the wireless device in a radio resource control (RRC) idle state or an RRC inactive state, one or more transport blocks via the periodic resource;
- determining, by the base station distributed unit, that a time alignment timer associated with the periodic resource is expired;
- and sending, by the base station distributed unit to the base station central unit, one or more messages requesting a release of the wireless device context by the base station central unit, the one or more messages comprising a cause value indicating that the release of the wireless device context is based on the expiration of the time alignment timer.
A base station distributed unit comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station distributed unit to:
- send, to a base station central unit, a wireless device context comprising a configuration of a periodic resource of a wireless device;
- receive, from the wireless device in a radio resource control (RRC) idle state or an RRC inactive state, one or more transport blocks via the periodic resource;
- determine that a time alignment timer associated with the periodic resource is expired;
- and send, to the base station central unit, one or more messages requesting a release of the wireless device context by the base station central unit, the one or more messages comprising a cause value indicating that the release of the wireless device context is based on the expiration of the time alignment timer.
A system, comprising:
- a base station central unit comprising:
- one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station central unit to:
- receive, from a base station distributed unit, a wireless device context comprising a configuration of a periodic resource of a wireless device;
- send, to the wireless device in a radio resource control (RRC) idle state or RRC inactive state, via the base station distributed unit, one or more RRC messages comprising configuration parameters of the periodic resource;
- and
- receive, from the base station distributed unit, one or more messages requesting a release of the wireless device context by the base station central unit, the one or more messages comprising a cause value indicating that the release of the wireless device context is based on expiration of a time alignment timer associated with the periodic resource;
- and
- the base station distributed unit, wherein the base station distributed unit comprises:
- one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station distributed unit to:
- send, to the base station central unit, the wireless device context;
- send, to the wireless device, the one or more RRC messages;
- receive, from the wireless device in the RRC idle state or the RRC inactive state, one or more transport blocks via the periodic resource;
- determine, by the base station distributed unit, that the time alignment timer for the periodic resource is expired;
- and
- send, to the base station central unit, the one or more messages.
