A method for relaying a signal in a wireless communication system is provided. The method comprises receiving in at least one of a base station and a relay station information regarding a mobile station group (MSG) of a mobile station, scheduling within a given duration uplink information to be transmitted from a first mobile station and downlink information to be transmitted to at least one mobile station, wherein the first mobile station is in each of the at least one mobile station's MSG, receiving in a relay station the uplink information and the downlink information to be transmitted within the given duration, network coding the uplink information and the downlink information in the relay station, and transmitting from the relay station a network-coded packet, wherein the network-coded packet can be received by the base station and the at least one mobile station.

A method for communicating data based on an unlicensed band in a wireless communication system comprising a first type network entity and a second type network entity which is different. The first type network entity comprises a cellular base station and the second type network entity comprises a Femto-cell base station. In the method, a cellular base station identifies at least one Femto-cell base station incurring interference and instructs the identified base station to operate on an unlicensed band. The technical features can be used to improve the performance of the wireless network, and/or to reduce the effect of interference.

Based on a proposed method, the UE can initiate a certain timer in order not to allow non-emergency calls when warning notification is given in a certain area. In particular, the UE can receive a paging message including warning indication from a network, and starting a delay timer upon receiving the paging message if the UE belongs to a delay-tolerant category. The UE performs a random access procedure after the delay timer is expired. Namely, the UE that receives the paging message for warning, such as the ETWS and CMAS, immediately check whether it belongs to a certain category proposed by this document to trigger a delay timer to wait for a certain period of time until it attempt the call initiation procedure.

In one design, a method to change a network-assigning mechanism and to use a distributed UE-selecting mechanism with the minimum possible information transferred from the network to the UE is proposed. In particular, it provides mechanism to define a lower bound and an upper bound for the extended wait time. For instance, the method comprises transmitting a RRC connection request message to a network, wherein an establishment cause of the RRC connection request message is set to be delay tolerant or low priority; receiving information associated with a first wait time included in an RRC connection reject/release message from the network; and performing a radio access to the network with a delay which is determined based on a lower bound of the first wait time and a upper bound of the first wait time.

A method for performing random access is provided. The method is performed for random access procedure based on a lower bound of back-off time and an upper bound of back-off time. Based on the proposed method, subsequent transmission of a random access preamble is determined by control information included in a random access response. The control information explicitly or implicitly indicates an upper bound and a lower bound of a back-off time value. An exact back-off time is selected from a uniform distribution between the lower bound and the upper bound.

A method and user equipment (UE) for communicating data between a serving layer and a served layer are provided. In one design, a serving layer adjusts the value for the served layer before it forwards the value to the served layer. In another design, The serving layer forwards the value to the served layer without adjusting but the served layer adjusts the received value. A predefined mapping rule can be further applied when adjusting the value between two layers.

A method for determining a proper preamble allocation mode is provided. The method is applicable to a base station communication with a number of human to human UEs and machine to machine UEs. The base station collects information from different types of UEs to figure out arrival rates for human to human type random access attempts and machine to machine type random access attempts. The base station selects one allocation mode out of two different allocation modes. In one mode, random access preambles are dedicatedly allocated to machine to machine type UES. In the other mode, preambles are commonly allocated to different types of UEs. The base station indicates the selected allocation mode by using system information block such as SIB2.

A method and apparatus for reporting statistic information associated with random access procedure and back-off process are provided. The method proposes a number of back-off interval reporting modes. The reporting modes include the first mode in which a sequence indicating every back-off interval applied during the back-off process is reported, the second mode in which a total sum of the every back-off interval applied during the back-off process is reported, the third mode in which an average of the every back-off interval applied during the back-off process is reported, and the fourth mode in which a variance of the every back-off interval applied during the back-off process is reported. The reporting information is transmitted via RRC signaling.
