Signal transmission method for MTC and apparatus for same
The present invention relates to a wireless communication system. Specifically, the present invention relates to a method and an apparatus for controlling network connection of a terminal in a wireless communication system, the invention relating to a method for controlling network for same, wherein the method comprises the steps of: receiving system information comprising control information for adjusting a network connection work connection on the base station, based on the control information, wherein, when the control information allows the network connection or when the terminal is a non-LC UE type, a random connection process is performed in the process for the network connection, and when the control information does not allow the network connection and the terminal is an LC UE type, the random connection process is skipped in the process for the network connection.
1. A method for controlling network access by a User Equipment (UE) in a wireless communication system, the method comprising:
receiving system information related with network access of a specific type device from a Base Station (BS), wherein the specific type device supports a transport block size of up to 1000-bits and has only a single receipt antenna;
if the system information allows network access of the specific type device or the UE is not the specific type device, performing a random access procedure for network initial access as to the BS and a procedure for receiving downlink data; and
if the system information does not allow network access of the specific type device and the UE is the specific type device, skipping the random access procedure for network initial access as to the BS,
wherein the procedure for receiving the downlink data includes:
receiving a first Physical Downlink Control Channel (PDCCH) including control information indicating a first set of Resource Blocks (RBs) corresponding to a current downlink signal reception frequency region for the UE at a subframe #n, wherein n is a non-negative integer,
receiving a second PDCCH including control information indicating a second set of RBs allocated for Physical Downlink Shared Channel (PDSCH) at a subframe #n+k, wherein k is a positive integer,
when there is a partial overlap region between the first set of RBs and the second set of RBs, receiving the PDSCH through only the partial overlap region at the subframe #n+k, and
when there is not any overlap region between the first set of RBs and the second set of RBs, skipping a detection procedure for receiving the PDSCH at the subframe #n+k, and setting the second set of RBs as a next downlink signal reception frequency region for the UE at a subframe after the subframe #n+k.
2. The method according to claim 1 , wherein the system information includes information indicating whether the BS supports functions related with the specific type device.
3. The method according to claim 1 , wherein the system information includes a System Information Block1 (SIB1).
4. The method according to claim 1 , wherein the system information includes a Master Information Block (MIB) and the control information indicating the network access control of the specific type device is received in a reserved bit of the MIB.
5. A User Equipment (UE) in a wireless communication system, the UE comprising:
a Radio Frequency (RF) unit; and
a processor,
wherein the processor is configured to:
receive system information related with network access of a specific type device from a Base Station (BS),
wherein the specific type device supports a transport block size of up to 1000-bits and has only a single receipt antenna,
if the system information allows network access of the specific type device or the UE is not the specific type device, perform a random access procedure for network initial access to the BS and a procedure for receiving downlink data, and
if the system information does not allow network access of the specific type device and the UE is the specific type device, skip the random access procedure for network initial access to the BS,
wherein the procedure for receiving the downlink data includes:
receiving a first Physical Downlink Control Channel (PDCCH) including control information indicating a first set of Resource Blocks (RBs) corresponding to a current downlink signal reception frequency region for the UE at a subframe #n, wherein n is a non-negative integer,
receiving a second PDCCH including control information indicating a second set of RBs allocated for Physical Downlink Shared Channel (PDSCH) at a subframe #n+k, wherein k is a positive integer,
when there is a partial overlap region between the first set of RBs and the second set of RBs, receiving the PDSCH through only the partial overlap region at the subframe #n+k, and
when there is not any overlap region between the first set of RBs and the second set of RBs, skipping a detection procedure for receiving the PDSCH at the subframe #n+k, and setting the second set of RBs as a next downlink signal reception frequency region for the UE at a subframe after the subframe #n+k.
6. The UE according to claim 5 , wherein the system information includes information indicating whether the BS supports functions related with the specific type device.
7. The UE according to claim 5 , wherein the system information includes a System Information Block1 (SIB1).
8. The UE according to claim 5 , wherein the system information includes a Master Information Block (MIB) and the control information indicating the network access control of the specific type device is received in a reserved bit of the MIB.
