First message repetition for mission critical user equipments

A method of configuring one or more user equipments, UEs, to repeatedly transmit a first message while a repetition condition is met, characterized by:

• including in a second message a repetition parameter, wherein the repetition parameter indicates that a UE receiving the second message including the repetition parameter is allowed to or must transmit the first message repeatedly while the repetition condition is met if one or more criteria are met;
• and
• transmitting the second message, wherein
• the repetition condition is that physical random access channel, PRACH, reattempt has not occurred, and
• said one or more criteria includes that the UE receiving the second message is (i) a UE configured to provide a mission critical, MC, service, (ii) a UE configured to provide one or more multimedia priority services, or (iii) any one of (i) and (ii).

A method of configuring a user equipment, UE, to repeatedly transmit a first message while a repetition condition is met, characterized by:

• receiving a second message including a repetition parameter, wherein the repetition parameter indicates that a UE receiving the second message including the repetition parameter is allowed to or must transmit the first message repeatedly while the repetition condition is met if one or more criteria are met;
• based on the received second message, determining whether to repeatedly transmit the first message;
• and
• transmitting the first message, wherein
• the repetition condition is that physical random access channel, PRACH, reattempt has not occurred, and
• said one or more criteria includes that the UE receiving the second message is (i) a UE configured to provide a mission critical, MC, service, (ii) a UE configured to provide one or more multimedia priority services, or (iii) any one of (i) and (ii).

A base station for configuring one or more user equipments, UEs, to repeatedly transmit a first message while a repetition condition is met, the base station comprising:

• a memory;
• and
• processing circuitry coupled to the memory, wherein the base station is configured to:
• include in a second message a repetition parameter, wherein the repetition parameter indicates that a UE receiving the second message including the repetition parameter is allowed to or must transmit the first message repeatedly while the repetition condition is met if one or more criteria are met;
• and
• transmit the second message, wherein
• the repetition condition is that physical random access channel, PRACH, reattempt has not occurred, and
• said one or more criteria includes that the UE receiving the second message is (i) a UE configured to provide a mission critical, MC, service, (ii) a UE configured to provide one or more multimedia priority services, or (iii) any one of (i) and (ii).
