Abstract
A wireless communication method includes transmitting, from a base station (BS), multiple downlink (DL) signals. The wireless communication method further includes receiving, with a user equipment (UE), two or more DL signals of the multiple DL signals, and notifying, with the BS, the UE of a number of the two or more DL signals. The two or more DL signals are associated with a Physical Random Access Channel (PRACH) resource.
Claims10
A wireless communication method comprising:
- transmitting, from a base station (BS), multiple downlink (DL) signals;
- receiving, with a user equipment (UE), two or more DL signals of the multiple DL signals;
- notifying, with the BS, the UE of a number of the two or more DL signals assigned to a group;
- and
- controlling, with the UE, transmission of a Physical Random Access Channel (PRACH) based on the number of the two or more DL signals of the group,
- wherein the two or more DL signals are associated with a resource of the PRACH for the group, and
- wherein the multiple DL signals are Synchronization Signals (SSs).
4 more elements
A base station (BS) comprising:
- a transmitter that transmits, to a user equipment (UE):
- multiple downlink (DL) signals that comprise two or more DL signals;
- and
- a number of the two or more DL signals assigned to a group;
- and
- a processor that allocates the two or more DL signals to a Physical Random Access Channel (PRACH) resource for the group,
- wherein the processor controls a reception of the PRACH transmitted based on the number of the two or more DL signals from the UE for the group, and
- wherein the multiple DL signals are Synchronization Signals (SSs).
5 more elements
A user equipment (UE) comprising:
- a receiver that receives, from a base station (BS):
- two or more downlink (DL) signals;
- and
- a number of the two or more DL signals assigned to a group;
- and
- a processor that controls transmission of a Physical Random Access Channel (PRACH) based on the number of the two or more DL signals of the group,
- wherein the two or more DL signals are associated with a resource of the PRACH for the group,
- wherein the two or more DL signals are included in multiple DL signals transmitted from the BS, and
- wherein the multiple DL signals are Synchronization Signals (SSs).
