    摘要： The present invention provides a method for resource allocation, a base station and a mobile communication terminal. The method includes: setting a persistent radio resource set and a complementary resource set pre-allocated to a terminal; determining a radio resource to be used according to the size of a packet to be transmitted by the terminal or the base station. According to one embodiment of the present invention, when a whole packet cannot be transmitted by using the pre-allocated persistent resource, the complementary resource can be allocated to the terminal so that the packet doesn't need to be divided, time delay is reduced, physical layer control information is decreased and the number of accommodated terminal users is increased. The present invention is applicable to any service in which packets arrive periodically, such as VoIP service and real-time service.

    摘要： Communication systems may benefit from a control channel for contention based transmission and collision avoidance. For example, communication systems of the third generation partnership project (3GPP) long term evolution (LTE) and LTE-Advanced may use such control channels for contention based transmission. In particular, such control channels may be valuable with respect to LTE-based local area network (LTE-LAN). A method, according to certain embodiments, may include preparing control information for a contention based physical uplink shared channel. The method may also include transmitting and/or receiving the control information on a physical uplink control channel and a control only physical uplink shared channel, or only on the control only physical uplink shared channel.

    摘要： In the present disclosure, the UE apparatus is classified by type and the demodulation information to use in channel estimation of MUI signals is determined based on the type of the UE apparatus. The channel estimating apparatus for MUI signals has: a user type determining circuit that determines whether a UE apparatus corresponding to an own station belongs to a first type user or a second type user and determines demodulation information to use in channel estimation of MUI signals based on the type of the UE apparatus corresponding to the own station; and a channel estimating circuit that performs channel estimation of a multi-user interference signal based on the determined demodulation information to use in channel estimation of MUI signals. With this structure, it is possible to improve channel estimation accuracy and further to improve the performance of data reception and user and cell throughputs.

    摘要： A method for uplink control signaling in CoMP operation is described. The method includes allocating a first set of CCEs for an associated transmission from an AP to an associated UE. The method also includes transmitting, to a RRH, a message including an indication of the first set of CCEs. The message including the indication of a first set of CCEs is received at the RRH. The method also includes allocating, by the RRH, a second set of CCEs for an associated transmission from the RIM to an associated UE. A UE receives the transmission of downlink control information beginning at a first CCE. The method includes receiving a PUCCH resource offset parameter, the PUCCH resource offset parameter indicating the reception point for the UE. The UE determines an uplink control channel resource based on the first CCE and the PUCCH resource offset parameter.
