A method for performing random access in a wireless communication system is provided. The method includes transmitting a preamble for random access in uplink, receiving a random access response message including back-off information as a response to the preamble, and performing back-off using the back-off information when the random access has failed.

A method of receiving semi-persistent scheduling (SPS) data performed by a user equipment (UE) in a multi-carrier system is provided. The method includes receiving, on a first carrier, information on a second carrier for second SPS data, the second carrier different from the first carrier, and receiving the second SPS data on the second carrier. The network can implicitly reconfigure the SPS from one CC to another CC without releasing the old SPS configuration in the one CC and setting up a new SPS configuration for the another CC, so that the complexity of SPS reconfiguration procedure is simplified and clarified.

A method of receiving system information performed by a user equipment (UE) is provided. The method includes receiving, from a network, an indicator indicating a change of system information related to a point-to-multipoint service on a physical control channel, and receiving changed system information related to the point-to-multipoint service in response to the indication.

A method for a user equipment (UE) to receive a downlink signal, the method including receiving a first downlink control channel identified by a temporary cell identifier (Temporary C-RNTI) from a base station, the first downlink control channel including a first downlink assignment signal having a new data indicator (NDI) with a first value; receiving a second downlink control channel identified by a cell identifier (C-RNTI) from the base station, the second downlink control channel including a second downlink assignment signal having the NDI with a second value; and determining if the NDI has been toggled compared to the NDI previously received from the base station. Further, the UE ignores the NDI with the first value received through the first downlink control channel identified by the temporary cell identifier (Temporary C-RNTI). The method also includes receiving the downlink signal based on the determining.
摘要:
A method and system for processing buffer status reports (BSRs) such that when BSR triggering is performed, the size(s) of the necessary sub-header(s) are also to be considered together in addition to the BSR size. The steps of checking whether any padding region is available in a MAC PDU that was constructed, comparing the number of padding bits with the size of the BSR plus its sub-header, and if the number of padding bits is larger than the size of the BSR plus its sub-header, triggering BSR are performed. Doing so allows the sub-header(s) to be inserted or included into the MAC PDU or transport block (TB) or other type of data unit.

A method and apparatus of generating a data block for a plurality of uplink frequencies is provided. The apparatus determines a size of a data field of the data block so that each data block matches a minimum of a first amount of data and second amount of data. The first amount of data is allowed to be transmitted by a first grant on a first uplink frequency and the second amount of data is allowed to be transmitted by a second grant on a second uplink frequency. The apparatus generates at least one data block so that the amount of data in the generated data blocks is less than multiple times the minimum of the first amount of data and the second amount of data.
摘要:
A method of allocating resources in a wireless communication system includes configuring priorities for a plurality of logical channels according to a first criterion, wherein each of the plurality of logical channels has each priority and allocating resources to a subset of the plurality of logical channels according to a second criterion to transfer data through a transport channel, wherein the subset of the plurality of logical channels is configured with same priority. It is possible to reliably provide various services through a method of processing radio bearers having the equal priorities.

Transmitting information using a preamble of a Random Access Channel (RACH) in an Evolved Universal mobile Telecommunications System (E-UMTS) is provided. A preamble transmission is used to inform a base station of specific information when a terminal uses a RACH and the base station efficiently allocates radio resources for data transmission to the terminal according to the specific information. Delay time before the terminal transmits data is reduced and unnecessary consumption of radio resources is minimized.
