Abstract

A method by a wireless device is provided for controlling adaptive beam measurement capability. The method includes identifying a type of serving carrier of a serving cell and allocating at least one resource for beam measurement based on the type that was identified.

First claim

The invention claimed is:

1. A method by a wireless device for controlling adaptive beam measurement capability, the method comprising:
identifying a type of serving carrier of a serving cell, the type of serving carrier including one of a component carrier of a secondary cell (SCC), a component carrier of a primary cell (PCC), and a component carrier of a primary secondary cell (PSCC); and
allocating at least one resource for at least one beam measurement based on the type that was identified, the allocating the at least one resource including:
allocating an amount of memory or buffers to perform the at least one beam measurement;
allocating an amount of processing resources to perform the at least one beam measurement;
allocating a first number of beam measurements for all configured component carriers (CCs) with a first discontinuous reception (DRX) configuration;
allocating a second number of beam measurements for all configured CCs with a second discontinuous reception (DRX) configuration; and
distributing or scheduling at least one task associated with the one or more beam measurement; and

allocating the at least one resource for the at least one beam measurement including:
determining whether at least one of a PCC and PSCC is configured;
allocating a first resource for the at least one beam measurement of the SCC based on the type of serving carrier of the serving cell being a component carrier of a SCC, and a PCC or PSCC being configured;
allocating a second resource for the at least one beam measurement of the SCC based on the type of serving carrier of the serving cell being a component carrier of a SCC, and no PCC or PSCC being configured; and
performing the at least one beam measurement using the at least one resource allocated based on the type of serving carrier that was identified.

2. The method of claim 1 , wherein allocating the at least one resource for beam measurement based on the type comprises:
when the type of serving carrier of the serving cell is a component carrier of a PCC, allocating a first resource for the beam measurement on the PCC,
when the type of serving carrier of the serving cell is a component carrier of a PSCC, allocating a second resource for the beam measurement on the PSCC, and
when the type of serving carrier of the serving cell is a component carrier of a SCC, allocating a third resource for the beam measurement of the SCC.

3. The method of claim 2 , wherein:
the first resource comprises at least one resource for performing a first number of beam measurements on the PCC;
the second resource comprises at least one resource for performing a second number of beam measurements on the PSCC; and
the third resource comprises at least one resource for performing a third number of beam measurements on the SCC.

4. The method of claim 1 , wherein allocating the at least one resource for beam measurement based on the type comprises:
when the type of serving carrier of the serving cell is a component carrier of a PCC, allocating a first resource for the beam measurement on the PCC,

when the type of serving carrier of the serving cell is a component carrier of a PSCC, allocating a second resource for the beam measurement on the PSCC,
when the type of serving carrier of the serving cell is a component carrier of a SCC and a PCC or PSCC is configured, allocating a third resource for the beam measurement of the SCC; and
when the type of serving carrier of the serving cell is a component carrier of a SCC and no PCC or PSCC is configured, allocating a fourth resource for the beam measurement of the SCC.

5. The method of claim 4 , wherein:
the first resource comprises at least one resource for performing a first number of beam measurements on the PCC;
the second resource comprises at least one resource for performing a second number of beam measurements on the PSCC;
the third resource comprises at least one resource for performing a third number of beam measurements on the SCC; and
the fourth resource comprises at least one resource for performing a fourth number of beam measurements on the SCC.

6. The method of claim 1 , wherein performing the at least one beam measurement comprises performing at least one Reference Signal Received Power (RSRP) measurement.

7. The method of claim 1 , wherein performing the at least one beam measurement comprises performing at least one Reference Signal Received Quality (RSRQ) measurement.

8. The method of claim 1 , wherein performing the at least one beam measurement comprises performing at least one Signal to Interference and Noise Ratio (SINR) measurement.

9. The method of claim 1 , wherein performing the at least one beam measurement corresponds to measuring a secondary synchronization signal (SSS) in a syncronisation signal block (SSB).

10. The method of claim 1 , wherein performing the at least one beam measurement corresponds to measuring a channel state information reference symbol (CSI-RS).

11. The method of claim 1 , wherein allocating the at least one resource for the beam measurement based on the type that was identified comprises:
allocating a first number of beam measurements for all configured and activated component carriers (CCs); and
allocating a second number of beam measurements for all configured and deactivated CCs.

12. A wireless device for controlling adaptive beam measurement capability, the wireless device comprising:
memory operable to store instructions; and
processing circuitry operable to execute the instructions to cause the wireless device to:
identify a type of serving carrier of a serving cell, the type of serving carrier including one of a component carrier of a secondary cell (SCC), a component carrier of a primary cell (PCC, and a component carrier of a primary secondary cell (PSCC); and
allocate at least one resource for at least one beam measurement based on the type that was identified, the processing circuitry being operable to allocate the at least one resource by:
allocating an amount of memory or buffers to perform the at least one beam measurement;
allocating an amount of processing resources to perform the at least one beam measurement;
allocating a first number of beam measurements for all configured component carriers (CCs) with a first discontinuous reception (DRX) configuration, and allocating a second number of beam measurements for all configured CCs with a second discontinuous reception (DRX) configuration; and
distributing or scheduling at least one task associated with the at least one beam measurement;

allocating the at least one resource for the at least one beam measurement including:
determining whether at least one of a PCC and PSCC is configured;
allocating a first resource for the beam measurement of the SCC based on the type of serving carrier of the serving cell being a component carrier of a SCC, and a PCC or PSCC being configured; and
allocating a second resource for the beam measurement of the SCC based on the type of serving carrier of the serving cell being a component carrier of a SCC, and no PCC or PSCC being configured; and
performing the at least one beam measurement using the at least one resource allocated based on the type of serving carrier that was identified.

13. The wireless device of claim 12 , wherein allocating the at least one resource for beam measurement based on the type comprises:
