Handling collision for mini-slot-based and slot-based transmission
Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process one or more configuration transmissions from the gNB carrying a rule for Uplink (UL) collisions and process a first Downlink (DL) transmission and a second DL transmission. The second circuitry may be operable to identify a first UL transmission for the first DL transmission and a second UL transmission for the second DL transmission, the first UL transmission overlapping with the second UL transmission in at least one Orthogonal Frequency Division Multiplexing (OFDM) symbol. The third circuitry may be operable to generate at least one of the first UL transmission and the second UL transmission in accordance with the rule for UL collisions.
1. A User Equipment (UE) operable to communicate with a base station (BS) on a wireless network, comprising:
one or more processors to:
process one or more configuration transmissions from the BS carrying indicators of one or more pre-emption conditions; and
identify a received Physical Downlink Control Channel (PDCCH) transmission carrying a pre-emption indication in accordance with the one or more pre- emption conditions, wherein the received PDCCH transmission carrying the pre-emption indication occurs in a slot later in time than a puncturing instance, the pre-emption indication providing an offset between the slot and the puncturing instance, and wherein the pre-emption indication includes a set of one or more antenna port indices; and
an interface for receiving configuration transmissions and the PDCCH transmission.
2. The UE of claim 1 , wherein the one or more pre-emption conditions comprise at least one of: a monitoring activation condition, and a triggering condition.
3. The UE of claim 2 , wherein the triggering condition comprises a failure to decode a code block of an ongoing Hybrid Automatic Repeat Request (HARQ) process.
4. The UE of claim 2 , wherein the triggering condition comprises a presence of an active Hybrid Automatic Repeat Request (HARQ) process.
5. The UE of claim 1 , wherein the pre-emption indication is carried by a dedicated Downlink Control Information (DCI) format.
6. The UE of claim 5 , wherein a Cyclic Redundancy Check (CRC) of DCI carrying the pre-emption indication is scrambled with a dedicated Radio Network Temporary Identifier (RNTI).
7. The UE of claim 1 , wherein the pre-emption indication further includes an indicator of an offset to increase Hybrid Automatic Repeat Request (HARQ) feedback delay for a corresponding pre-empted process.
8. The UE of claim 1 , wherein the preemption indication further includes a field in a Downlink Control Information (DCI) scheduling a retransmission for an impacted Hybrid Automatic Repeat Request (HARQ) process.
9. The UE of claim 1 , wherein the preemption indication further includes a bitmap having a size corresponding to one or more Code Block Groups (CBGs) in a given Hybrid Automatic Repeat Request (HARQ) process.
10. The UE of claim 1 , wherein the pre-emption indication further includes a bitmap having at least one bit indicating whether one or more corresponding Code Block Groups (CBGs) are pre-empted in a previous scheduling occasion of a current Hybrid Automatic Repeat Request (HARQ) process.
11. The UE of claim 1 , wherein the pre-emption indication further includes a bitmap having a bit indicating a code block (CB) in a corresponding Code Block Group (CBG).
12. The UE of claim 1 , wherein a time domain part of the pre-emption indication is a bitmap corresponding to symbols of an impacted slot, the bitmap having a length of 14 bits.
13. The UE of claim 1 , wherein the signaling of the pre-emption indication occurs in the slot that is later in time than the puncturing instance.
14. A non-transitory machine readable storage media having machine executable instructions that, when executed, cause one or more processors of a User Equipment (UE) operable to communicate with a base station (BS) on a wireless network to perform an operation comprising:
process one or more configuration transmissions from the BS carrying indicators of one or more pre-emption conditions; and
identify a received Physical Downlink Control Channel (PDCCH) transmission carrying a pre-emption indication in accordance with the one or more pre-emption conditions,
wherein signaling of the received PDCCH transmission carrying the pre-emption indication occurs in a slot later in time than a puncturing instance, the pre-emption indication providing an offset between the signaling slot and the puncturing instance, and
wherein the pre-emption indication includes a set of one or more antenna port indices.
15. The non-transitory machine readable storage media of claim 14 , wherein the one or more preemption conditions comprise at least one of: a monitoring activation condition, and a triggering condition.
16. The non-transitory machine readable storage media of claim 15 , wherein the triggering condition comprises a failure to decode a code block of an ongoing Hybrid Automatic Repeat Request (HARQ) process.
17. The non-transitory machine readable storage media of claim 15 , wherein the triggering condition comprises a presence of an active Hybrid Automatic Repeat Request (HARQ) process.
18. The non-transitory machine readable storage media of claim 14 , wherein the pre- emption indication is carried by a dedicated Downlink Control Information (DCI) format.
19. The non-transitory machine readable storage media of claim 18 , wherein a Cyclic Redundancy Check (CRC) of the DCI carrying the pre-emption indication is scrambled with a dedicated Radio Network Temporary Identifier (RNTI).
20. The non-transitory machine readable storage media of claim 14 , wherein signaling of the pre-emption indication occurs in the slot that is later in time than the puncturing instance.
