Abstract

Claims (74)

1 . A user equipment comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the user equipment to:

transmit, to the network entity, first data in a small data transmission procedure in a non-connected state; and

transmit, to the network entity, an indication related to a transmission of second data after the transmission of the first data, the second data becoming available after the first data having been transmitted while the small data transmission procedure is ongoing, the second data being a new data, and the second data being to be transmitted when the user equipment is in a radio resource control (RRC) connected state,

wherein the indication for transmission of second data is transmitted before receiving, from the network entity, a RRC resume message; and/or

the indication for transmission of second data is transmitted after transmitting the first data.

2 . The user equipment of claim 1 , wherein the user equipment is further caused to:

receive, from the network entity, an RRC resume message indicating to transit the user equipment to the RRC connected state.

3 . The user equipment of claim 1 , wherein the indication for transmission of second data is or comprises one or more of:

a scheduling request;

a buffer status report; and/or

an indication that more data is expected.

4 . The user equipment of claim 1 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, further cause the user equipment to one or more of:

receive, from the network entity, a resource configuration pertaining to the transmission of the indication of the second data and/or to the transmission of the second data; and/or

receive, from the network entity, threshold information whether to transmit the indication for transmission of second data.

5 . The user equipment of claim 4 , the resource configuration is or comprises one or more of:

a resource configuration for transmitting a scheduling request;

a resource configuration tor transmitting a buffer status report;

a resource configuration for a configured grant;

a resource configuration for a random access preamble;

an uplink grant; and/or

a resource configuration including one or more PUCCH and/or one or more PUSCH resources.

6 . The user equipment of claim 4 , wherein the at least one memory and the computer program code are further configured to, with the at least one processor, further cause the user equipment to one or more of:

receive the threshold information as part of a release message;

receive the resource configuration as part of a or the release message;

receive the resource configuration as part of a contention resolution message in response to the transmission of the first data;

receive the resource configuration as a broadcast message; and/or

receive the resource configuration as part of a release message after the transmission of the indication.

7 . The user equipment of claim 1 , wherein the user equipment is further caused to:

transition to the RRC connected state for transmitting the second data; and

transmit, to the network entity, the second data in the RRC connected mode.

8 . A method performed by a user equipment, the method comprising:

transmitting, to a network entity, first data in a small data transmission procedure in a non-connected state; and

transmitting, to the network entity, an indication related to a transmission of second data after the transmission of the first data,

the second data becoming available after the first data having been transmitted while the small data transmission procedure is ongoing, the second data is a new data, and the second data is to be transmitted when the user equipment is in a radio resource control (RRC) connected state, and

wherein the indication for transmission of second data is transmitted before receiving, from the network entity, a RRC resume message; and/or

the indication for transmission of second data is transmitted after transmitting the first data.

9 . The method of claim 8 , wherein the indication for transmission of second data is or comprises one or more of:

a scheduling request;

a buffer status report; and/or

an indication that more data is expected.

10 . The method of claim 8 , further comprising:

receiving, from the network entity, a resource configuration pertaining to the transmission of the indication of the second data and/or to the transmission of the second data; and

receiving, from the network entity, threshold information whether to transmit the indication for transmission of second data.

11 . The method of claim 10 , the resource configuration is or comprises one or more of:

a resource configuration for transmitting a scheduling request;

a resource configuration tor transmitting a buffer status report;

a resource configuration for a configured grant;

a resource configuration for a random access preamble;

an uplink grant; and/or

a resource configuration including one or more PUCCH and/or one or more PUSCH resources.

12 . The method of claim 10 , further comprising:

receive the threshold information as part of a release message;

receive the resource configuration as part of a or the release message;

receive the resource configuration as part of a contention resolution message in response to the transmission of the first data;

receive the resource configuration as a broadcast message; and/or

receive the resource configuration as part of a release message after the transmission of the indication.

13 . The method of claim 8 , further comprising:

receiving, from the network entity, an RRC resume message indicating to transit the user equipment to the RRC connected state.

14 . The method of claim 8 , further comprising:

transitioning to the RRC connected state for transmitting the second data; and

transmitting, to the network entity, the second data in the RRC connected mode.

15 . A non-transitory computer readable medium comprising program instructions which, when executed by an user equipment, cause the user equipment to perform at least the following:

transmitting, to a network entity, first data in a small data transmission procedure in a non-connected state; and

transmitting, to the network entity, an indication related to a transmission of second data after the transmission of the first data,

the second data becoming available after the first data having been transmitted while the small data transmission procedure is ongoing, the second data is a new data, and the second data is to be transmitted when the user equipment is in a radio resource control (RRC) connected state,

wherein the indication for transmission of second data is transmitted before receiving, from the network entity, a RRC resume message; and/or

the indication for transmission of second data is transmitted after transmitting the first data.

16 . The non-transitory computer readable medium of claim 15 , wherein the program instructions further cause the user equipment to perform:

receiving, from the network entity, an RRC resume message indicating to transit the user equipment to the RRC connected state.

17 . The non-transitory computer readable medium of claim 15 , wherein the program instructions further cause the user equipment to perform:

transitioning to the RRC connected state for transmitting the second data; and

transmitting, to the network entity, the second data in the RRC connected mode.
