Abstract
A user equipment (UE) 102 receives, from a radio access network (RAN) 105, a configuration for uplink transmission to the RAN 105 when a radio connection between the UE 102 and a radio access network (RAN) 105 is suspended (e.g., event 602); detects, at a first time when the radio connection is suspended, that a message for transmitting to the RAN 105 is available (e.g., event 604); and refrains, at the first time in response to determining that an uplink (UE) resource corresponding to the configuration is not available until a second time subsequent to the first time, from transmitting the message to the RAN 105 (e.g., event 608).
Claims20
A method implemented in a user equipment (UE), the method for managing resources and comprising:
- receiving, from a radio access network (RAN), a configuration for uplink transmission to the RAN when a radio connection between the UE and the RAN is suspended, the configuration including an indication of a time threshold;
- initiating, at a first time when the radio connection is suspended, a radio resource resume procedure;
- detecting, when the radio connection is suspended, that an uplink (UL) resource for transmitting a message to the RAN is available at a second time subsequent to the first time;
- and
- initiating, when a time difference between the first time and the second time is greater than the time threshold, a random access (RA) procedure.
An apparatus, functioning as a user equipment (UE), comprising:
- a transceiver;
- and
- one or more processors configured to:
- receive, from a radio access network (RAN), a configuration for uplink transmission to the RAN when a radio connection between the UE and the RAN is suspended, the configuration including an indication of a time threshold;
- initiate, at a first time when the radio connection is suspended, a radio resource resume procedure;
- detect, when the radio connection is suspended, that an uplink (UL) resource for transmitting a message to the RAN is available at a second time subsequent to the first time;
- and
- initiate, when a time difference between the first time and the second time is greater than the time threshold, a random access (RA) procedure.
