System and method for enabling reliable and low latency communication
A system and method for multiplexing traffic. A wireless device such as a user equipment (UE) may receive a first signal over first resources assigned to carry a first downlink transmission from a base station, and receive a first downlink control indication (DCI) message from the base station. The first DCI message may include a pre-emption region (PR) indication and a PR bitmap, and the PR indication may indicate a location of a time-frequency region. The PR bitmap may include bits associated with different portions of the time-frequency region, and each of the bits in the PR bitmap may indicate whether a preemptive downlink transmission is present in the corresponding portion of the time-frequency region.
1. A method comprising:
receiving, by an apparatus from a base station (BS), a data transmission over resources assigned to carry downlink transmissions; and
receiving, by the apparatus from the BS, a group common (GC) downlink control information (DCI), the GC DCI including a pre-emption indication (PI), the PI including a notification of a time-frequency region, the PI further including a bitmap indicating pre-emption information of the time-frequency region, wherein a configuration of the bitmap indicates a first number of bit groups and a second number of one or more bits in each of the bit groups, and wherein one or more bits in a same bit group correspond to one or more frequency divisions of a same time division.
2. The method of claim 1 , wherein the PI is a post indication indicating pre-emption events before a monitoring occasion of the PI.
3. The method of claim 1 , the notification of the time-frequency region indicating locations of the time-frequency region.
4. The method of claim 1 , each bit of bits in the bitmap indicating whether a scheduled downlink transmission is present in a corresponding portion of the time-frequency region.
5. The method of claim 1 , the bitmap including 14 bits with time-domain granularities and frequency-domain granularities of the time-frequency region.
6. An apparatus comprising:
a non-transitory storage medium storing instructions; and
one or more processors in communication with the non-transitory storage medium, wherein the one or more processors execute the instructions to cause the apparatus to:
receive, from a base station (BS), a data transmission over resources assigned to carry downlink transmissions; and
receive, from the BS, a group common (GC) downlink control information (DCI), the GC DCI including a pre-emption indication (PI), the PI including a notification of a time-frequency region, the PI further including a bitmap indicating pre-emption information of the time-frequency region, wherein a configuration of the bitmap indicates a first number of bit groups and a second number of one or more bits in each of the bit groups, and wherein one or more bits in a same bit group correspond to one or more frequency divisions of a same time division.
7. The apparatus of claim 6 , wherein the PI is a post indication indicating pre-emption events before a monitoring occasion of the PI.
8. The apparatus of claim 6 , the notification of the time-frequency region indicating locations of the time-frequency region.
9. The apparatus of claim 6 , each bit of bits in the bitmap indicating whether a scheduled downlink transmission is present in a corresponding portion of the time-frequency region.
10. The apparatus of claim 6 , the bitmap including 14 bits with time-domain granularities and frequency-domain granularities of the time-frequency region.
11. A method comprising:
transmitting, by a base station (BS), a data transmission over resources assigned to carry downlink transmissions; and
transmitting, by the BS, a group common (GC) downlink control information (DCI), the GC DCI including a pre-emption indication (PI), the PI including a notification of a time-frequency region, the PI further including a bitmap indicating pre-emption information of the time-frequency region, wherein a configuration of the bitmap indicates a first number of bit groups and a second number of one or more bits in each of the bit groups, and wherein one or more bits in a same bit group correspond to one or more frequency divisions of a same time division.
12. The method of claim 11 , wherein the PI is a post indication indicating pre-emption events before a monitoring occasion of the PI.
13. The method of claim 11 , the notification of the time-frequency region indicating locations of the time-frequency region.
14. The method of claim 11 , each bit of bits in the bitmap indicating whether a scheduled downlink transmission is present in a corresponding portion of the time-frequency region.
15. The method of claim 11 , the bitmap including 14 bits with time-domain granularities and frequency-domain granularities of the time-frequency region.
16. A base station (BS) comprising:
a non-transitory storage medium storing instructions; and
one or more processors in communication with the non-transitory storage medium, wherein the one or more processors execute the instructions to cause the BS to:
transmit a data transmission over resources assigned to carry downlink transmissions; and
transmit a group common (GC) downlink control information (DCI), the GC DCI including a pre-emption indication (PI), the PI including a notification of a time-frequency region, the PI further including a bitmap indicating pre-emption information of the time-frequency region, wherein a configuration of the bitmap indicates a first number of bit groups and a second number of one or more bits in each of the bit groups, and wherein one or more bits in a same bit group correspond to one or more frequency divisions of a same time division.
17. The BS of claim 16 , wherein the PI is a post indication indicating pre-emption events before a monitoring occasion of the PI.
18. The BS of claim 16 , the notification of the time-frequency region indicating locations of the time-frequency region.
19. The BS of claim 16 , each bit of bits in the bitmap indicating whether a scheduled downlink transmission is present in a corresponding portion of the time-frequency region.
20. The BS of claim 16 , the bitmap including 14 bits with time-domain granularities and frequency-domain granularities of the time-frequency region.
