Abstract

The present invention provides a method and an apparatus for reducing the amount of upper layer signals. Also, the present invention provides a method and an apparatus comprising: defining a new identifier for transmitting an upper layer signal for user equipment in a specific mode; and transmitting the upper layer signal by means of scrambling by using the new identifier, transmitting along with an error detection sign by using the new identifier, transmitting by using a user equipment-specific reference signal by using the new identifier, or transmitting based on control information transmitted by using the new identifier.

Claims

1-13. -13. (canceled)

14. A method for receiving, by a user equipment, a signal, the method comprising:

receiving a master information block on a physical broadcast channel; and

receiving a system information block based on the master information block,

wherein the master information block includes information on a time-frequency resource for reception of the system information block.

15. The method according to claim 14, wherein the master information block further includes information on a downlink bandwidth, information on a physical hybrid ARQ indicator channel (PHICH) configuration and information on a system frame number.

16. The method according to claim 14, wherein the system information block is system information block type 1 (SIB1) which contains information relevant when evaluating whether the user equipment is allowed to access a cell and defines scheduling of other system information.

17. The method according to claim 14, wherein the system information block is received on a physical downlink shared channel (PDSCH) separate from a PDSCH scheduled by a physical downlink control channel (PDCCH).

18. A user equipment for receiving a signal, the user equipment comprising:

a radio frequency (RF) unit, and

a processor configured to control the RF unit to;

receive a master information block on a physical broadcast channel; and

receive a system information block based on the master information block,

wherein the master information block includes information on a time-frequency resource for reception of the system information block.

19. The user equipment according to claim 18, wherein the master information block further includes information on a downlink bandwidth, information on a physical hybrid ARQ indicator channel (PHICH) configuration and information on a system frame number.

20. The user equipment according to claim 18, wherein the system information block is system information block type 1 (SIB1) which contains information relevant when evaluating whether the user equipment is allowed to access a cell and defines scheduling of other system information.

21. The user equipment according to claim 18, wherein the processor is configured to control the RF unit to receive the system information block on a physical downlink shared channel (PDSCH) separate from a PDSCH scheduled by a physical downlink control channel (PDCCH).

22. A method for transmitting, by a base station, a signal, the method comprising:

transmitting a master information block on a physical broadcast channel; and

transmitting a system information block based on the master information block,

wherein the master information block includes information on a time-frequency resource for reception of the system information block.

23. The method according to claim 22, wherein the master information block further includes information on a downlink bandwidth, information on a physical hybrid ARQ indicator channel (PHICH) configuration and information on a system frame number.

24. The method according to claim 22, wherein the system information block is system information block type 1 (SIB 1) which contains information relevant when evaluating whether the user equipment is allowed to access a cell and defines scheduling of other system information.

25. The method according to claim 22, wherein the system information block is transmitted on a physical downlink shared channel (PDSCH) separate from a PDSCH scheduled by a physical downlink control channel (PDCCH).

26. A base station for transmitting a signal, the base station comprising:

a radio frequency (RF) unit, and

a processor configured to control the RF unit to;

transmit a master information block on a physical broadcast channel; and

transmit a system information block based on the master information block,

wherein the master information block includes information on a time-frequency resource for reception of the system information block.

27. The base station according to claim 26, wherein the master information block further includes information on a downlink bandwidth, information on a physical hybrid ARQ indicator channel (PHICH) configuration and information on a system frame number.

28. The base station according to claim 26, wherein the system information block is system information block type 1 (SIB1) which contains information relevant when evaluating whether the user equipment is allowed to access a cell and defines scheduling of other system information.

29. The base station according to claim 26, wherein the processor is configured to control the RF unit to transmit the system information block on a physical downlink shared channel (PDSCH) separate from a PDSCH scheduled by a physical downlink control channel (PDCCH).
