Abstract

Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication are generally described herein. The UE may receive downlink control information (DCI) that indicates an allocation for a new radio (NR) physical uplink shared channel (NR PUSCH) transmission, by the UE, in a channel of multiple physical resource blocks (PRBs) in a slot that comprises: a predetermined data region, and a predetermined control region reserved for NR physical uplink control channel (NR PUCCH) transmissions. The DCI may be configurable to indicate whether the allocation includes one or more of the PRBs in the control region. The allocation may include one or more of the PRBs in one or more symbol periods in the data region and may be configurable to include one or more of the PRBs in one or more symbol periods in the control region.

First claim

What is claimed is:

1. An apparatus comprising:
one or more processors, configured to cause a user equipment (UE) to:
decode downlink control information (DCI) that indicates an allocation for a new radio (NR) physical uplink shared channel (NR PUSCH) transmission, by the UE, in a channel of multiple frequency resources in a slot that comprises:
a data region of one or more symbol periods, and
a reference signal region of one or more symbol periods reserved for NR reference signal transmissions, wherein the DCI is configurable to indicate whether the allocation includes one or more of the multiple frequency resources in the reference signal region, and wherein one or more bits in the DCI provide this indication;

store at least a portion of the DCI; and
determine the allocation based on the DCI, wherein the allocation includes one or more of the multiple frequency resources in one or more of the symbol periods of the data region, wherein the allocation is configurable to include one or more of the multiple frequency resources in one or more of the symbol periods of the reference signal region.

2. The apparatus according to claim 1 , wherein:
for the allocation, the multiple frequency resources included in the data region are first multiple frequency resources,
for the allocation, the multiple frequency resources included in the reference signal region are second multiple frequency resources, and
the allocation is configurable for first multiple frequency resources and second multiple frequency resources that are the same.

3. The apparatus according to claim 1 , wherein:
for the allocation, the multiple frequency resources included in the data region are first multiple frequency resources,
for the allocation, the multiple frequency resources included in the reference signal region are second multiple frequency resources, and
the allocation is configurable for first multiple frequency resources and second multiple frequency resources that are different.

4. The apparatus according to claim 1 , wherein:
the DCI includes a bitmap for which bit positions are mapped to at least some of the multiple frequency resources in accordance with a predetermined mapping, and values of the bit positions of the bitmap indicate whether corresponding multiple frequency resources are reserved for the NR reference signal transmissions in the reference signal region.

5. The apparatus according to claim 1 , wherein:
the DCI includes a start multiple frequency resource or an end multiple frequency resource, and
the one or more processors are further configured to determine, based at least partly on the start multiple frequency resource or the end multiple frequency resource, the one or more multiple frequency resources in the reference signal region for the allocation.

6. The apparatus according to claim 1 , wherein:
the DCI indicates a range of multiple frequency resources for which NR PUSCH transmissions are permissible in the reference signal region, and
for the allocation, the multiple frequency resources included in the data region are first multiple frequency resources,
the one or more processors are further configured to determine, for the allocation, second multiple frequency resources for the reference signal region based at least partly on an intersection between the first multiple frequency resources and the range of multiple frequency resources indicated in the DCI.

7. The apparatus according to claim 1 , wherein:
the DCI includes an end symbol for the allocation for the NR PUSCH transmission, and
the one or more processors are further configured to determine that the NR PUSCH transmission is to be performed at least partly in the reference signal region if the end symbol for the allocation is included in the reference signal region.

8. The apparatus according to claim 1 , the one or more processors further configured to:
determine, based on the DCI, the allocation for the NR PUSCH transmission to include: contiguous first multiple frequency resources in contiguous symbol periods of the data region, and
if the indicator of the DCI indicates that the NR PUSCH transmission is to be performed at least partly in the reference signal region, contiguous second multiple frequency resources in one or more contiguous symbol periods of the reference signal region.

9. The apparatus according to claim 1 , wherein:
the DCI includes a bitmap for which bit positions are mapped to at least some of the multiple frequency resources in accordance with a predetermined mapping, and
values of the bit positions of the bitmap indicate whether corresponding multiple frequency resources are to be included in the allocation in the reference signal region.

10. The apparatus according to claim 1 , the one or more processors further configured to:
determine, based on the DCI, a division of the multiple frequency resources in the one or more symbols of the reference signal region to include:
first multiple frequency resources for the NR reference signal transmissions, and
second multiple frequency resources for sounding reference signal (SRS) transmissions; and

encode an SRS for transmission in the reference signal region in at least one of the second multiple frequency resources.

11. The apparatus according to claim 1 , the one or more processors further configured to:
encode data bits to generate the NR PUSCH transmission in accordance with the allocation.

12. The apparatus according to claim 1 , wherein the apparatus further includes a transceiver to receive the DCI.

13. The apparatus according to claim 1 , wherein the one or more processors includes a baseband processor to decode the DCI and to determine the allocation.

14. The apparatus according to claim 1 , wherein the UE is arranged to operate in accordance with a new radio (NR) protocol.

15. A non-transitory, computer-readable storage medium storing program instructions that, when executed by one or more processors of a User Equipment (UE), cause the UE to:
decode downlink control information (DCI) that indicates an allocation for a new radio (NR) physical uplink shared channel (NR PUSCH) transmission, by the UE, in a channel of multiple frequency resources in a slot that comprises:
a data region of one or more symbol periods, and
a reference signal region of one or more symbol periods reserved for NR reference signal transmissions, wherein the DCI is configurable to indicate whether the allocation includes one or more of the multiple frequency resources in the reference signal region, and wherein one or more bits in the DCI provide this indication;

store at least a portion of the DCI; and
determine the allocation based on the DCI, wherein the allocation includes one or more of the multiple frequency resources in one or more of the symbol periods of the data region, wherein the allocation is configurable to include one or more of the multiple frequency resources in one or more of the symbol periods of the reference signal region.

16. The non-transitory, computer-readable storage medium of claim 15 , wherein:
for the allocation, the multiple frequency resources included in the data region are first multiple frequency resources,
for the allocation, the multiple frequency resources included in the reference signal region are second multiple frequency resources, and
the allocation is configurable for first multiple frequency resources and second multiple frequency resources that are the same.

17. The non-transitory, computer-readable storage medium of claim 15 , wherein:
