Abstract

Claims (36)

1. A user equipment (UE), comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the UE to:

transmit both of a first data transmission over a first radio access technology and a second data transmission over a second radio access technology or receive both of the first data transmission over the first radio access technology and the second data transmission over the second radio access technology; and

detect a collision between the first data transmission and the second data transmission;

compare, in response to the first radio access technology being of a different radio access technology type than the second radio access technology and in further response to an attribute of the second data transmission indicative of whether the second data transmission is an initial transmission or a retransmission indicating that the second data transmission is the retransmission, a first priority level of the first data transmission to a second priority level of the second data transmission, a priority level threshold, or some combination thereof; and

upon detection of the collision, selectively drop one of the first and second data transmissions based on a set of selection criteria, the set of selection criteria comprising the attribute, wherein the second data transmission is dropped in response to the attribute indicating the retransmission and the first priority level being greater than the second priority level, the priority level threshold, or some combination thereof, and the first data transmission is dropped in response to the attribute indicating that the second data transmission comprises the initial transmission.

2. The UE of claim 1 , wherein the first radio access technology is new radio, and the second radio access technology is long-term evolution.

3. The UE of claim 1 , wherein the collision between the first data transmission and the second data transmission occurs where the first and the second data transmissions overlap in a time domain.

4. The UE of claim 1 , wherein the priority level threshold is pre-configured and/or configured by a base station.

5. The UE of claim 1 , wherein

the first data transmission over the first radio access technology is transmitted by a transceiver;

the second data transmission over the second radio access technology is a retransmission received by the transceiver;

the at least one processor is configured to cause the UE to detect whether a corresponding initial transmission over the second radio access technology is successfully received by the transceiver; and

the first data transmission is dropped upon detection of unsuccessful reception of the initial transmission, and a retransmission of the second data transmission is not received upon successful reception of the initial transmission.

6. The UE of claim 1 , wherein

the first data transmission over the first radio access technology is received by a transceiver;

the second data transmission over the second radio access technology is a retransmission by the transceiver;

the at least one processor is configured to cause the UE to detect whether a corresponding initial transmission by the transceiver over the second radio access technology is successfully transmitted; and

the first data transmission is not received upon unsuccessful initial transmission, and the second data transmission is dropped upon successful initial transmission.

7. The UE of claim 1 , wherein the at least one processor is configured to cause the UE to schedule a third data transmission over the first radio access technology excluding overlapping resources for initial transmissions over the second radio access technology.

8. The UE of claim 7 , wherein the at least one processor is configured to cause the UE to schedule the third data transmission over the first radio access technology excluding overlapping resources for retransmissions over the second radio access technology.

9. The UE of claim 8 , wherein the scheduling of the third data transmission is based on comparison of its priority level and the second priority level of the second data transmission.

10. A method performed by a user equipment (UE), the method comprising:

scheduling a transmission of both of a first data transmission over a first radio access technology and a second data transmission over a second radio access technology or a reception of both of the first data transmission over the first radio access technology and the second data transmission over the second radio access technology;

detecting a collision between the first data transmission and the second data transmission;

comparing, in response to the first radio access technology being of a different radio access technology type than the second radio access technology and in further response to an attribute of the second data transmission indicative of whether the second data transmission is an initial transmission or a retransmission indicating that the second data transmission is the retransmission, a first priority level of the first data transmission to a second priority level of the second data transmission, a priority level threshold, or some combination thereof; and

upon detection of the collision, selectively dropping one of the first and second data transmissions based on a set of selection criteria, the set of selection criteria comprising the attribute, wherein the second data transmission is dropped in response to the attribute indicating the retransmission and the first priority level being greater than the second priority level, the priority level threshold, or some combination thereof, and the first data transmission is dropped in response to the attribute indicating that the second data transmission comprises the initial transmission.

11. The method of claim 10 , wherein the first radio access technology is new radio, and the second radio access technology is long-term evolution.

12. The method of claim 10 , wherein the collision between the first data transmission and the second data transmission occurs where the first and the second data transmissions overlap in a time domain.

13. A processor for wireless communication, comprising:

at least one controller coupled with at least one memory and configured to cause the processor to:

transmit and/or receive both of a first data transmission over a first radio access technology and a second data transmission over a second radio access technology or receive both of the first data transmission over the first radio access technology and the second data transmission over the second radio access technology;

detect a collision between the first data transmission and the second data transmission;

compare, in response to the first radio access technology being of a different radio access technology type than the second radio access technology and in further response to an attribute of the second data transmission indicative of whether the second data transmission is an initial transmission or a retransmission indicating that the second data transmission is the retransmission, a first priority level of the first data transmission to a second priority level of the second data transmission, a priority level threshold, or some combination thereof; and

upon detection of the collision, selectively drop one of the first and second data transmissions based on a set of selection criteria, the set of selection criteria comprising the attribute, wherein the second data transmission is dropped in response to the attribute indicating the retransmission and the first priority level being greater than the second priority level, the priority level threshold, or some combination thereof, and the first data transmission is dropped in response to the attribute indicating that the second data transmission comprises the initial transmission.
