Abstract

The present application is related to a method and apparatus for resource allocation for EMBB/URLLC in 3GPP 5G technology. A method for resource allocation performed by abase station (BS) includes: transmitting, to a user equipment (UE), signaling indicating non-available resource on a carrier, wherein the non-available resource is reserved for a specific type of communication; and transmitting, to the UE, an indicator indicating allocated resource for transmitting data on the carrier, wherein the allocated resource includes at least part of the non-available resource.

First claim

What is claimed is:

1. A method for wireless communications performed by a base station, the method comprising:
transmitting, to a user equipment (UE), signaling indicating a non-available resource associated with a carrier, wherein the non-available resource is reserved for a type of wireless communication; and
transmitting, to the UE, an indicator indicating an allocated resource for a data transmission on the carrier, wherein the allocated resource includes at least part of the non-available resource, wherein the carrier is partitioned into a plurality of subbands, each subband of the plurality of subbands has a same bandwidth and a same subcarrier spacing, the signaling includes a bitmap, and each bit in the bitmap corresponds to a respective subband of the plurality of subbands and indicates whether the respective subband is available.

2. The method of claim 1 , wherein the signaling is at least one of radio resource control (RRC) signaling or downlink control information (DCI), wherein the DCI is at least one of DCI scheduling physical downlink shared channel (PDSCH), DCI scheduling physical uplink shared channel (PUSCH), or a group-common physical downlink control channel (PDCCH).

3. The method of claim 1 , wherein:
the signaling includes an index and the index corresponds to a corresponding subband reserved for the type of wireless communication; or
the signaling includes a state to indicate that each of the plurality of subbands are available.

4. The method of claim 1 , further comprising:
transmitting, to the UE, RRC signaling for configuring a bandwidth and a subcarrier spacing of a subband, wherein a number of physical resource blocks (PRBs) reserved as a guard band on each side of the subband reserved for the type of wireless communication is based on the bandwidth and the subcarrier spacing.

5. The method of claim 1 , wherein the signaling indicates a set of contiguous physical resource blocks (PRBs) associated with the carrier as non-available.

6. The method of claim 5 , wherein:
the signaling includes a downlink control information (DCI) and indicates both a starting PRB index and a number of PRBs in the set of contiguous PRBs;
the signaling includes radio resource control (RRC) signaling and indicates a number of PRBs of the set of contiguous PRBs, and the signaling further includes the DCI and further indicates a starting PRB index of the number of PRBs of the set of contiguous PRBs;
the signaling includes radio resource control (RRC) signaling and indicates both a starting PRB index and a number of PRBs of the set of contiguous PRBs; or
the signaling includes radio resource control (RRC) signaling and indicates a frequency offset between a lowest PRB of a synchronization signal and/or physical broadcast channel (SS/PBCH) block and a lowest PRB of a frequency bandwidth reserved for the type of wireless communication.

7. The method of claim 5 , wherein the signaling indicates a resource reservation pattern from a set of preconfigured resource reservation patterns.

8. The method of claim 7 , wherein:
each of the set of preconfigured resource reservation patterns defines a starting PRB index and a number of contiguous PRBs reserved for the type of wireless communication;
each of the set of preconfigured resource reservation patterns defines a bitmap and each bit in the bitmap corresponds to one PRB of the carrier and indicates whether the PRB is available or not-available for transmission; or
at least one resource reservation pattern of the set of preconfigured resource reservation patterns indicates that no resource in a given slot on the carrier is reserved for the type of wireless communication.

9. The method of claim 5 , wherein the signaling includes radio resource control (RRC) signaling and indicates a frequency offset between an edge of the carrier and an edge of a frequency bandwidth reserved for the type of wireless communication.

10. The method of claim 9 , wherein:
the signaling further includes a DCI to indicate a number of reserved PRBs in a guard band of the frequency bandwidth; or
the signaling further includes one bit in a DCI to indicate whether a guard band for the type of wireless communication exists.

11. The method of claim 1 , wherein the non-available resource includes a minimum bandwidth covering a synchronization signal (SS)/physical broadcast channel (PBCH) block for initial access.

12. A base station, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the base station to:
transmit, to a user equipment (UE), signaling indicating a non-available resource associated with a carrier, wherein the non-available resource is reserved for a type of wireless communication; and
transmit, to the UE, an indicator indicating an allocated resource for a data transmission on the carrier, wherein the allocated resource includes at least part of the non-available resource, wherein the carrier is partitioned into a plurality of subbands, each subband of the plurality of subbands has a same bandwidth and a same subcarrier spacing, the signaling includes a bitmap, and each bit in the bitmap corresponds to a respective subband of the plurality of subbands and indicates whether the respective subband is available.

13. 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:
receive, from a base station, signaling indicating a non-available resource associated with a carrier, wherein the non-available resource is reserved for a type of wireless communication; and
receive, from the base station, an indicator indicating an allocated resource for a data transmission on the carrier, wherein the allocated resource includes at least part of the non-available resource, wherein the carrier is partitioned into a plurality of subbands, each subband of the plurality of subbands has a same bandwidth and a same subcarrier spacing, the signaling includes a bitmap, and each bit in the bitmap corresponds to a respective subband of the plurality of subbands and indicates whether the respective subband is available.

14. The UE of claim 13 , wherein the signaling is at least one of radio resource control (RRC) signaling or downlink control information (DCI), wherein the DCI is at least one of a DCI scheduling physical downlink shared channel (PDSCH), a DCI scheduling physical uplink shared channel (PUSCH), and a group-common physical downlink control channel (PDCCH).

15. The UE of claim 13 , further comprising: receiving, from the base station, RRC signaling for configuring a bandwidth and a subcarrier spacing of a subband.

16. The UE of claim 13 , wherein the signaling indicates a set of contiguous physical resource blocks (PRBs) associated with the carrier as non-available, or indicates a resource reservation pattern from a set of preconfigured resource reservation patterns.

17. The UE of claim 16 , wherein the signaling includes radio resource control (RRC) signaling and indicates a frequency offset between an edge of the carrier and an edge of a frequency bandwidth reserved for the type of communication.

18. The UE of claim 16 , wherein the signaling includes a radio resource control (RRC) signaling and indicates a frequency offset between the lowest PRB of a synchronization signal and/or physical broadcast channel (SS/PBCH) block and the lowest PRB of a frequency bandwidth reserved for the type of wireless communication.
