Abstract

Methods and apparatus are described. A method, implemented in a wireless transmit/receive unit (WTRU), includes receiving a single radio resource control (RRC) connection reconfiguration request. The single RRC connection reconfiguration request includes individually, for each of a plurality of cells, physical configuration information. One of the plurality of cells is a primary cell and other cells of the plurality of cells are non-primary cells. Measurement configuration information is received that configures the WTRU to send a measurement report on a condition that a neighboring cell is better than a non-primary cell by an amount.

Claims

1. A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:

receiving a single radio resource control (RRC) connection reconfiguration request, the single RRC connection reconfiguration request including individually, for each of a plurality of cells, physical configuration information, wherein one of the plurality of cells is a primary cell and other cells of the plurality of cells are non-primary cells; and

receiving measurement configuration information that configures the WTRU to send a measurement report performing a handover of a control channel, wherein the control channel is received from a primary cell, wherein a handover for a downlink traffic channel is performed—

on a condition that a neighboring cell is better than a non-primary cell by an amount.

2. The method of claim 1, further comprising:

communicating with the plurality of cells using cooperative multipoint communication (CoMP).

3. The method claim 1, wherein the measurement report is based on at least one measurement related to channel quality.

4. The method of claim 1, wherein the physical configuration information includes at least one of a physical uplink control channel (PUCCH) configuration or a physical uplink shared channel (PUSCH) configuration.

5. The method of claim 1, further comprising sending the measurement report.

6. A wireless transmit/receive unit (WTRU) comprising:

a receive unit configured to;

receive a single radio resource control (RRC) connection reconfiguration request, the single RRC connection reconfiguration request including individually, for each of a plurality of cells, physical configuration information, wherein one of the plurality of cells is a primary cell and other cells of the plurality of cells are non-primary cells, and

receive measurement configuration information that configures the WTRU to send a measurement report on a condition that a neighboring cell is better than a non-primary cell by an amount.

7. The WTRU of claim 6, further comprising:

a processing unit configured to control the WTRU to communicate with the plurality of cells using cooperative multipoint communication (CoMP).

8. The WTRU of claim 6, wherein the measurement report is based on at least one measurement related to channel quality.

9. The WTRU of claim 6, wherein the physical configuration information includes at least one of a physical uplink control channel (PUCCH) configuration or a physical uplink shared channel (PUSCH) configuration.

10. The WTRU of claim 6, further comprising a transmit/receive element configured to send the measurement report.

11. The WTRU of claim 10, further comprising an antenna, in communication with the transmit/receive element, configured to send and receive radio frequency (RF) communications.

12. A base station comprising:

a transmit unit configured to;

send a single radio resource control (RRC) connection reconfiguration request, the single RRC connection reconfiguration request including individually, for each of a plurality of cells, physical configuration information, wherein one of the plurality of cells is a primary cell and other cells of the plurality of cells are non-primary cells, and

send measurement configuration information that configures a wireless transmit/receive unit (WTRU) to send a measurement report on a condition that a neighboring cell is better than a non-primary cell by an amount.

13. The base station of claim 12, wherein the measurement report is based on at least one measurement related to channel quality.

14. The base station of claim 12, wherein the physical configuration information includes at least one of a physical uplink control channel (PUCCH) configuration or a physical uplink shared channel (PUSCH) configuration.
