Abstract

Claims (33)

1 . A method in a network device, the method comprising:

receiving configuration information including at least one of multimedia broadcast single frequency network (MBSFN) configuration or time division duplex (TDD) configuration for an evolved universal terrestrial radio access network (E-UTRAN); and

transmitting the configuration information to a user equipment, wherein the network device is associated with a radio access technology different from E-UTRAN.

2 . A method as defined in claim 1 , wherein the MBSFN configuration includes at least one of a MBSFN subframe allocation list or neighbor cell configuration information.

3 . A method as defined in claim 1 , wherein the network device receives the configuration information in a message sent by the E-UTRAN.

4 . A method as defined in claim 3 , wherein the message is sent using Si signaling.

5 . A method as defined in claim 1 , wherein the configuration information includes at least one of a MBSFN subframe configuration list or a TDD configuration and the configuration information is transmitted to the user equipment in information elements including at least one of an E-UTRA frequency and priority information list, an E-UTRA frequency list, or E-UTRA Neighbor Cells.

6 . A method as defined in claim 1 , wherein transmitting the configuration information comprises transmitting combined MBSFN allocation information indicated in a bit stream.

7 . A method as defined in claim 1 , wherein the network device receives the configuration information from at least one of the user equipment or a second user equipment.

8 . A method as defined in claim 7 , further comprising instructing a second user equipment to read the configuration information from a system information block of the E-UTRAN and to report the configuration information to the network device.

9 . A method as defined in claim 8 , wherein the instructing comprises instructing the second user equipment to read at least one of system information block 2 or system information block 3 when the configuration information is the MBSFN configuration and instructing at least one of the second user equipment or a third user equipment to read system information block 1 when the configuration information is the TDD configuration.

10 . A method as defined in claim 8 , further comprising selecting the second user equipment from among multiple user equipment communicating with the network device, wherein selecting the second user equipment comprises analyzing measurement capabilities of the second user equipment.

11 . A method as defined in claim 10 , wherein analyzing the measurement capabilities of the second user equipment comprises determining that the second user equipment is capable of reading the system information block without utilizing at least one of a measurement gap or a compressed mode.

12 . A method as defined in claim 1 , wherein the at least one of the MBSFN configuration or the TDD configuration are for a neighbor frequency of the E-UTRAN.

13 . A network device comprising a processor configured to:

receive configuration information including at least one of multimedia broadcast single frequency network (MBSFN) configuration or time division duplex (TDD) configuration for an evolved universal terrestrial radio access network (E-UTRAN); and

transmit the configuration information to a user equipment, wherein the network device is associated with a radio access technology different from E-UTRAN.

14 - 34 . (canceled)

35 . A method in a user equipment camped on or connected to a radio access technology different from an evolved universal terrestrial radio access network (E-UTRAN), the method comprising:

receiving a system information block from a E-UTRAN, the system information block including configuration information for at least one of multimedia broadcast single frequency network (MBSFN) configuration or time division duplex (TDD) configuration;

storing the configuration information in a cache; and

measuring neighbor E-UTRAN cells based on the configuration information stored in the cache.

36 . A method as defined in claim 35 , wherein the user equipment receives the system information block via radio access technology different from E-UTRAN.

37 . A method as defined in claim 35 , wherein the user equipment receives the system information block via E-UTRAN radio access technology.

38 . A method as defined in claim 35 , wherein the configuration information is associated with neighbor E-UTRAN cells in a frequency to measure.

39 . A method as defined in claim 35 , further comprising repeating the receiving after a period of time.

40 . A method as defined in claim 39 , wherein the period of time is determined based on a mobility state of the user equipment.

41 . A method as defined in claim 39 , wherein the period of time is determined based on a multicast control channel (MCCH) modification period.

42 . A user equipment camped on or connected to a radio access technology different from an evolved universal terrestrial radio access network (E-UTRAN), the user equipment comprising a processor configured to:

receive a system information block from a E-UTRAN, the system information block including configuration information for at least one of multimedia broadcast single frequency network (MBSFN) configuration or time division duplex (TDD) configuration;

store the configuration information in a cache; and

measure neighbor E-UTRAN cells based on the configuration information stored in the cache.
