Buffer management for multiple radio access technologies

A base station (BS) comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to:
• receive, from a user equipment (UE), information indicative of an overall size of a buffer at the UE for storing data received from the BS and a first number of resources the UE is capable of using for communicating between the UE and the BS using a first radio access technology (RAT);
• determine a second number of resources for communicating between the UE and the BS using the first RAT based on the received information;
• and
• transmit first encoded data using the first RAT and second encoded data using a second RAT to the UE, wherein bits for the first encoded data are based on an assumed size of a first portion of the buffer assumed allocated for storing data received by the UE using the first RAT, wherein the assumed size of the first portion is based on the first number of resources and the second number of resources, and wherein bits for the second encoded data are based on an assumed size of a second portion of the buffer assumed allocated for storing data received by the UE using the second RAT, wherein the assumed size of the second portion is based on the overall size of the buffer and the assumed size of the first portion, wherein the assumed size of the first portion is equal to the second number of resources divided by the first number of resources multiplied by the overall size of the buffer, wherein the assumed size of the second portion is equal to the overall size of the buffer minus the size of the first portion, and wherein the assumed size of the second portion is independent of a third number of resources the UE is capable of using for communicating between the UE and the BS using the second RAT.

A base station (BS) comprising:

• means for receiving, from a user equipment (UE), information indicative of an overall size of a buffer at the UE for storing data received from the BS and a first number of resources the UE is capable of using for communicating between the UE and the BS using a first radio access technology (RAT);
• means for determining a second number of resources for communicating between the UE and the BS using the first RAT based on the received information;
• and
• means for transmitting first encoded data using the first RAT and second encoded data using a second RAT to the UE, wherein bits for the first encoded data are based on an assumed size of a first portion of the buffer assumed allocated for storing data received by the UE using the first RAT, wherein the assumed size of the first portion is based on the first number of resources and the second number of resources, and wherein bits for the second encoded data are based on an assumed size of a second portion of the buffer assumed allocated for storing data received by the UE using the second RAT, wherein the assumed size of the second portion is based on the overall size of the buffer and the assumed size of the first portion, wherein the assumed size of the first portion is equal to the second number of resources divided by the first number of resources multiplied by the overall size of the buffer, wherein the assumed size of the second portion is equal to the overall size of the buffer minus the size of the first portion, and wherein the assumed size of the second portion is independent of a third number of resources the UE is capable of using for communicating between the UE and the BS using the second RAT.

A non-transitory computer readable storage medium that stores instructions that when executed by a base station (BS) causes the base station to perform a method for buffer management for a user equipment (UE) for multiple radio access technologies, the method comprising:

• receiving, at the BS from the UE, information indicative of an overall size of a buffer at the UE for storing data received from the BS and a first number of resources the UE is capable of using for communicating between the UE and the BS using a first radio access technology (RAT);
• determining, by the BS, a second number of resources for communicating between the UE and the BS using the first RAT based on the received information;
• and
• transmitting, by the BS, first encoded data using the first RAT and second encoded data using a second RAT to the UE, wherein bits for the first encoded data are based on an assumed size of a first portion of the buffer assumed allocated for storing data received by the UE using the first RAT, wherein the assumed size of the first portion is based on the first number of resources and the second number of resources, and wherein bits for the second encoded data are based on an assumed size of a second portion of the buffer assumed allocated for storing data received by the UE using the second RAT, wherein the assumed size of the second portion is based on the overall size of the buffer and the assumed size of the first portion, wherein the assumed size of the first portion is equal to the second number of resources divided by the first number of resources multiplied by the overall size of the buffer, wherein the assumed size of the second portion is equal to the overall size of the buffer minus the size of the first portion, and wherein the assumed size of the second portion is independent of a third number of resources the UE is capable of using for communicating between the UE and the BS using the second RAT.
