USER EQUIPMENT AND METHOD OF COMMUNICATION OF SAME
A user equipment (UE) and a method of communication of the same are provided. The method includes receiving, by a UE, a first information and a second information, wherein the first information and the second information are used to determine a frequency location of a physical uplink control channel (PUCCH). This provides PUCCH resource allocation determination.
1 . A method of communication of a user equipment (UE), comprising:
receiving, by a UE, a first information and a second information, wherein the first information and the second information are used to determine a frequency location of a physical uplink control channel (PUCCH).
2 . The method of claim 1 , wherein the first information is in a radio resource control (RRC) configuration.
3 . The method of claim 1 , wherein the first information comprises at least two configurations with corresponding configuration indexes.
4 . The method of claim 3 , wherein each configuration of the first information comprises a first parameter, the first parameter is used to indicate a interlace index corresponding to a selected interlace.
5 . The method of claim 4 , wherein each configuration of the first information further comprises a second parameter, the second parameter is used to indicate a resource block (RB) set index corresponding to a selected RB set.
6 . The method of claim 1 , wherein the second information is in a downlink control information (DCI).
7 . The method of claim 3 , wherein the second information comprises a first indication field, the first indication field is used to select one of the configuration indexes of the first information.
8 . The method of claim 5 , wherein the frequency location of the PUCCH is determined by overlapped RBs between the selected interlace and the selected RB set.
9 . The method of claim 5 , wherein the RB set index is an index of the selected RB set in a cell usable bandwidth of a cell.
10 . The method of claim 9 , wherein the RB set index in the cell usable bandwidth has indexes staring from 0 to X−1 in an ascending order in a frequency domain, where X is a number of RB sets in the cell usable bandwidth.
11 . A user equipment (UE), comprising:
a memory;
a transceiver; and
a processor coupled to the memory and the transceiver;
wherein the processor is configured to control the transceiver to receive a first information and a second information, wherein the first information and the second information are used to determine a frequency location of a physical uplink control channel (PUCCH).
12 . The UE of claim 11 , wherein the first information is in a radio resource control (RRC) configuration.
13 . The UE of claim 11 wherein the first information comprises at least two configurations with corresponding configuration indexes.
14 . The UE of claim 13 , wherein each configuration of the first information comprises a first parameter, the first parameter is used to indicate a interlace index corresponding to a selected interlace.
15 . The UE of claim 14 , wherein each configuration of the first information further comprises a second parameter, the second parameter is used to indicate a resource block (RB) set index corresponding to a selected RB set.
16 . The UE of claim 15 , wherein the frequency location of the PUCCH is determined by overlapped RBs between the selected interlace, the selected RB set, and an active uplink bandwidth part.
17 . The UE of claim 15 , wherein the RB set index is an index of the selected RB set in the active uplink bandwidth part.
18 . The UE of claim 17 , wherein the RB set index in the active uplink bandwidth part has indexes from 0 to Y−1 in an ascending order in a frequency domain, where Y is a number of the RB sets in the active uplink bandwidth part.
19 . The UE of claim 17 , wherein the selected RB set in the active uplink bandwidth part is derived from RB sets in a cell usable bandwidth of a cell and the active uplink bandwidth part.
20 . The UE of claim 19 , wherein the RB set index and locations of the RB sets in the cell usable bandwidth are obtained based on a third parameter and the cell usable bandwidth.
