Abstract

Embodiments disclosed herein provide a method for managing a resource in a wireless communication system. The method includes allocating, by a base station, the resource for a data transmission from a User Equipment (UE) by indicating at least one bandwidth part in a total bandwidth supported by the UE. The resource is further allocated by indicating a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Control Channel (PDSCH) according to a configured subcarrier spacing and a CP length within the at least one bandwidth part, and by indicating an allocation of Resource Blocks (RBs) within the at least one bandwidth part.

First claim

1 - 15 . (canceled)

16 . A method by a base station for managing a resource in a wireless communication system, comprising:
allocating, the resource for a data transmission from a User Equipment (UE) by: indicating at least one bandwidth part in a total bandwidth supported by the UE; indicating a PDCCH and a PDSCH according to a configured subcarrier spacing and a CP length within the at least one bandwidth part; and indicating an allocation of Resource Blocks (RBs) within the at least one bandwidth part.

17 . The method of claim 16 , wherein a size of groups of the RBs depends on a duration of the data transmission.

18 . The method of claim 16 , wherein the allocation of RBs are indicated using one of different DCI formats, a flag in a DCI format for interpreting a Radio Access (RA) type, a flag in a DCI format for interpreting an allocation of RBs from among a defined a size of groups of RBs, explicit indication of an allocation of RBs via a DCI and an implicit determination based on a size of a configured bandwidth part.

19 . The method of claim 16 , further comprising:
identifying whether an allocation of the RBs for each of the bandwidth parts are one of same and different; and causing to perform one of:
MU-MIMO multiplexing when a size of a group of the RBs for each of the bandwidth parts are same, and
signaling UEs about an allocation of the RBs to be used and performing MU-MIMO multiplexing.

20 . A method by a User Equipment (UE) for managing a resource in a wireless communication system, comprising:
tuning to a frequency range; determining at least one active bandwidth part from a set of bandwidth parts configured by a base station for a data transmission from the UE; and performing the data transmission within the at least one active bandwidth parts using associated numerology of the at least one active bandwidth part.

21 . The method of claim 20 , further comprising:
determining that a size of the at least one active bandwidth part is one within a frequency range; and re-tuning the at least one active bandwidth part to a location where a SS block exists.

22 . A base station for managing a resource in a wireless communication system, comprising:
a memory; a processor; a resource controller communicatively coupled to the memory and the processor, configured for:
allocating, by a base station, the resource for a data transmission from a User Equipment (UE) by:
indicating at least one bandwidth part in a total bandwidth supported by the UE;
indicating a PDCCH and a PDSCH according to a configured subcarrier spacing and a CP length within the at least one bandwidth part; and
indicating a number of Resource Blocks (RBs) within the at least one bandwidth part.

23 . The base station of claim 22 , wherein a size of groups of the RBs depends on a duration of the data transmission.

24 . The base station of claim 22 , wherein the number of RBs are indicated using one of different DCI formats, a flag in a DCI format for interpreting a Radio Access (RA) type, a flag in a DCI format for interpreting an allocation of RBs from among a defined a size of groups of RBs, explicit indication of an allocation of RBs via a DCI and an implicit determination based on a size of a configured bandwidth part.

25 . The base station of claim 22 , wherein the resource controller:
identifies whether an allocation of the RBs for each of the bandwidth parts are one of same and different; and cause to perform one of:
MU-MIMO multiplexing when a size of a group of the RBs for each of the bandwidth parts are same, and
signaling UEs about an allocation of the RBs to be used and perform MU-MIMO multiplexing.

26 . A user equipment (UE) for managing a resource in a wireless communication system, comprising:
a memory; a processor; a resource controller communicatively coupled to the memory and the processor, configured for:
tuning to a frequency range;
determining at least one active bandwidth part from a set of bandwidth parts configured by a base station for a data transmission from the UE; and
performing the data transmission within the at least one active bandwidth parts using associated numerology of the at least one active bandwidth part.

27 . The user equipment of claim 26 , wherein the resource controller is further configured for:
determining that a size of the at least one active bandwidth part is one within a frequency range; and re-tuning the at least one active bandwidth part to a location where a SS block exists.
