Abstract

A method of dynamic memory management in a user equipment (UE) is provided. The method includes receiving, by the UE, transport block size (TBS) information, from a base station (BS), associated with a data packet to be transmitted by the BS to the UE; identifying, by the UE, a plurality of empty bins and a size of each of the plurality of empty bins in a memory of the UE; detecting, by the UE, a presence of one or more empty bins, among the plurality of empty bins in the memory, with a size of each of the one or more empty bins greater than the TBS of the data packet; and allocating, by the UE, a smallest size empty bin, with a size greater than the TBS of the data packet, among the one or more empty bins to the data packet.

Claims

1. A method of dynamic memory management in a user equipment (UE), the method comprising:

receiving, by the UE, transport block size (TBS) information, from a base station (BS), associated with a data packet to be transmitted by the BS to the UE;

identifying, by the UE, a plurality of empty bins and a size of each of the plurality of empty bins in a memory of the UE;

detecting, by the UE, a presence of one or more empty bins, among the plurality of empty bins in the memory, with a size of each of the one or more empty bins greater than the TBS of the data packet; and

allocating, by the UE, a smallest size empty bin, with a size greater than the TBS of the data packet, among the one or more empty bins to the data packet.

2. The method of claim 1, further comprising:

detecting, by the UE, an absence of one or more empty bins, among the plurality of empty bins in the memory, with the size of each of the one or more empty bins greater than the TBS of the data packet;

reconfiguring, by the UE, the plurality of empty bins to create an empty bin with a size greater than the TBS of the data packet; and

allocating, by the UE, the created empty bin to the data packet.

3. The method of claim 1, further comprising transmitting, by the UE, information associated with one of a presence or an absence of the empty bin with a size greater than the TBS of the data packet to one or more associated BSs.

4. The method of claim 3, further comprising receiving the data packet from the BS in a case that the BS receives the information associated with the presence of an empty bin, in the memory of the UE, with a size greater than the TBS of the data packet.

5. The method of claim 2, wherein reconfiguring the plurality of empty bins comprises correlating the one or more empty bins with a size smaller than the TBS of the data packet until the empty bin with a size greater than the TBS of the data packet is created.

6. The method of claim 2, wherein reconfiguring the plurality of empty bins comprises reconfiguring the plurality of empty bins based on a link list.

7. The method of claim 1, wherein the data packet is associated with a hybrid automatic repeat request (HARQ) process.

8. The method of claim 1, further comprising transmitting a same data packet in each of one or more predefined time intervals to the UE in a first predefined HARQ process.

9. The method of claim 1, further comprising transmitting the data packet along with one or more redundant bits in each of one or more predefined time intervals to the UE in a second predefined hybrid automatic repeat request (HARQ) process.

10. A user equipment (UE) for dynamic memory management, the UE comprising:

a processor; and

a memory communicatively coupled to the processor, wherein the memory is configured to store processor-executable instructions, which, upon execution, cause the processor to;

receive transport block size (TBS) information, from a base station (BS), associated with a data packet to be transmitted by the BS to the UE;

identify a plurality of empty bins and a size of each of the plurality of empty bins in the memory of the UE;

detect a presence of one or more empty bins, among the plurality of empty bins in the memory, with a size of each of the one or more empty bins greater than the TBS of the data packet; and

allocate a smallest size empty bin among the one or more empty bins to the data packet.

11. The UE of claim 10, wherein the processor is configured to:

detect an absence of one or more empty bins, among the plurality of empty bins in the memory, with a size of each of the one or more empty bins greater than the TBS of the data packet;

reconfigure the plurality of empty bins to create an empty bin with a size greater than the TBS of the data packet; and

allocate the created empty bin to the data packet.

12. The UE of claim 10, wherein the processor is configured to transmit information associated with one of a presence or an absence of the empty bin with a size greater than the TBS of the data packet to one or more associated BSs.

13. The UE of claim 12, wherein the processor is further configured to receive the data packet from the BS when the BS receives the information associated with the presence of an empty bin, in the memory of the UE, with a size greater than the TBS of the data packet.

14. The UE of claim 11, wherein the processor is further configured to reconfigure the plurality of empty bins by correlating the one or more empty bins with a size smaller than the size of the TBS of the data packet until the empty bin with a size greater than the TBS of the data packet is created.

15. The UE of claim 11, wherein the processor is further configured to reconfigure the plurality of empty bins based on a link list.

16. The UE of claim 10, wherein the data packet is associated with a hybrid automatic repeat request (HARQ) process.

17. The UE of claim 10, wherein the processor is configured to transmit a same data packet in each of one or more predefined time intervals to the UE in a first predefined HARQ process.

18. The UE of claim 10, wherein the processor is configured to transmit the data packet along with one or more redundant bits in each of one or more predefined time intervals to the UE in a second predefined HARQ process.
