Abstract

A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to transmit or receive an enhanced mobile broadband (eMBB) signal or a massive machine type communication (MMTC) signal that may have its reception overridden by an ultra-reliable low latency communication (URLLC) transmission or have its reception at an evolved node B (eNB) interfered with by an URLLC transmission based on eNB-assisted usage of an outer code.

First claim

What is claimed is:

1 . A user equipment (UE) comprising:
a processor; and memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
transmit or receive an enhanced mobile broadband (eMBB) signal or a massive machine type communication (MMTC) signal that may have its reception overridden by an ultra-reliable low latency communication (URLLC) transmission or have its reception at an evolved node B (eNB) interfered with by an URLLC transmission based on eNB-assisted usage of an outer code.

2 . The UE of claim 1 , wherein the outer code is applied when eNB-assisted information configures the outer code.

3 . The UE of claim 1 , wherein the UE is configured with the outer code through RRC dedicated signaling.

4 . The UE of claim 1 , wherein a DCI format indicates the outer code for eMBB services transmission and reception.

5 . The UE of claim 1 , wherein UE capability of outer encode/decode is tied to a UE category that specifies an outer encoder/decoder for the UE.

6 . The UE of claim 1 , wherein a fixed coding rate outer code is applied based on eNB-assisted information.

7 . The UE of claim 6 , wherein the UE receives, from the eNB when a URLLC message is to be transmitted, a DCI format with one or more fields indicating a modulation and coding scheme (MCS) that are updated with a new inner coding rate.

8 . The UE of claim 6 , wherein the UE receives, from the eNB when a URLLC message is to be transmitted, a DCI format with a field indicating only an inner code coding rate.

9 . The UE of claim 1 , wherein a flexible coding rate outer code is applied based on eNB-assisted information.

10 . The UE of claim 9 , wherein:
a first MCS table set indicates an inner code coding rate, and a second MCS table set indicates both inner code and outer code coding rates, wherein the eNB configures the second MCS table set to the UE through RRC dedicated signaling when there is a URLLC message to be transmitted, otherwise, the eNB configures the first MCS table set in a DCI format.

11 . The UE of claim 9 , wherein a value of an MCS field in a DCI format indicates an outer code coding rate.

12 . An evolved node B (eNB) comprising:
a processor; and memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
transmit or receive an enhanced mobile broadband (eMBB) signal or a massive machine type communication (MMTC) signal that may have its reception overridden by an ultra-reliable low latency communication (URLLC) transmission or have its reception at a user equipment (UE) interfered with by an URLLC transmission based on eNB-assisted usage of an outer code.

13 . The eNB of claim 12 , wherein the outer code is applied when eNB-assisted information configures the outer code.

14 . The eNB of claim 12 , wherein the UE is configured with the outer code through RRC dedicated signaling.

15 . The eNB of claim 12 , wherein a DCI format indicates the outer code for eMBB services transmission and reception.

16 . The eNB of claim 12 , wherein UE capability of outer encode/decode is tied to a UE category that specifies an outer encoder/decoder for the UE.

17 . The eNB of claim 12 , wherein a fixed coding rate outer code is applied based on eNB-assisted information.

18 . The eNB of claim 17 , wherein when a URLLC message is to be transmitted, the eNB sends a DCI format with one or more fields indicating a modulation and coding scheme (MCS) that are updated with a new inner coding rate.

19 . The eNB of claim 17 , wherein when a URLLC message is to be transmitted, the eNB sends a DCI format with a field indicating only an inner code coding rate.

20 . The eNB of claim 12 , wherein a flexible coding rate outer code is applied based on eNB-assisted information.

21 . The eNB of claim 20 , wherein:
a first MCS table set indicates an inner code coding rate, and a second MCS table set indicates both inner code and outer code coding rates, wherein the eNB configures the second MCS table set to the UE through RRC dedicated signaling when there is a URLLC message to be transmitted, otherwise, the eNB configures the first MCS table set in a DCI format.

22 . The eNB of claim 20 , wherein a value of an MCS field in a DCI format indicates an outer code coding rate.
