Identifying a serving cell
Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network. The method further includes acquiring a timing of the network based on the synchronization signal, and transmitting a pilot signal in response to acquiring the timing of the network. The pilot signal may identify the UE and be concurrently receivable by the plurality of cells within the network. Other aspects, features, and embodiments are also claimed and described.
1. A method of wireless communication at a central node, comprising:
receiving, from a plurality of base stations, information corresponding to a number of pilot signals transmitted by a number of UEs;
identifying, based at least in part on the information, a serving cell for at least one of the UEs; and
transmitting to at least one of the base stations an indication of a set of one or more UEs for which the at least one of the base stations is identified as a serving cell.
2. The method of claim 1 , wherein the information corresponding to the number of pilot signals comprises measurements of the number of pilot signals.
3. The method of claim 1 , wherein identifying the serving cell for the at least one of the UEs comprises:
identifying the serving cell as a handover target for the at least one of the UEs.
4. A device for wireless communication at a central node, comprising a processor, memory in electronic communication with the processor, and instructions stored in the memory, the instructions being executable by the processor to:
receive, from a plurality of base stations, information corresponding to a number of pilot signals transmitted by a number of UEs;
identify, based at least in part on the information, a serving cell for at least one of the UEs; and
transmit to at least one of the base stations an indication of a set of one or more UEs for which the at least one of the base stations is identified as a serving cell.
5. The device of claim 4 , wherein the information corresponding to the number of pilot signals comprises measurements of the number of pilot signals.
6. The device of claim 4 , wherein the instructions executable by the processor to identify the serving cell for the at least one of the UEs comprise instructions executable by the processor to identify the serving cell as a handover target for the at least one of the UEs.
7. A device for wireless communication at a central node, comprising:
means for receiving, from a plurality of base stations, information corresponding to a number of pilot signals transmitted by a number of UEs;
processor for identifying, based at least in part on the information, a serving cell for at least one of the UEs; and
means for transmitting to at least one of the base stations an indication of a set of one or more UEs for which the at least one of the base stations is identified as a serving cell.
8. The device of claim 7 , wherein the information corresponding to the number of pilot signals comprises measurements of the number of pilot signals.
9. The device of claim 8 , wherein the processor for identifying the serving cell for the at least one of the UEs is configured to:
identify the serving cell as a handover target for the at least one of the UEs.
10. A non-transitory computer-readable medium storing computer-executable code for wireless communication at a central node, the code executable by a processor to:
receive, from a plurality of base stations, information corresponding to a number of pilot signals transmitted by a number of UEs;
identify, based at least in part on the information, a serving cell for at least one of the UEs; and
transmit to at least one of the base stations an indication of a set of one or more UEs for which the at least one of the base stations is identified as a serving cell.
11. The non-transitory computer-readable medium of claim 10 , wherein the information corresponding to the number of pilot signals comprises measurements of the number of pilot signals.
12. The non-transitory computer-readable medium of claim 10 , wherein the code executable by the processor to identify the serving cell for the at least one of the UEs comprise code executable by the processor to identify the serving cell as a handover target for the at least one of the UEs.
