摘要:
A backhaul radio is disclosed that operates in multipath propagation environments such as obstructed LOS conditions with uncoordinated interference sources in the same operating band. Such a backhaul radio may use a combination of interference mitigation procedures across multiple of the frequency, time, spatial and cancellation domains. Such backhaul radios may communicate with each other to coordinate radio resource allocations such that accurate interference assessment and channel propagation characteristics assessment may be determined during normal operation.

The present invention relates to a wireless communication system. In particular, the present invention relates to a method for a terminal to receive a downlink signal in a wireless communication system and to an apparatus for same, the method comprising the steps of: receiving, from a base station, a first piece of information indicating the start point of a multicast broadcast single frequency network (MBSFN) signal, receiving an MBSFN subframe having a plurality of orthogonal frequency division multiplexing (OFDM) symbols, and receiving the MBSFN signal from an OFDM symbol indicated by the first piece of information in the MBSFN subframe.

A method and apparatus for carrier scheduling in a multi-carrier system is provided. A terminal receives information, which indicates whether or not to perform a cross carrier scheduling process, from a base station. If it is determined, by means of said information, that the cross carrier scheduling process is to be performed, the terminal receives scheduling information about a second downlink carrier via a first downlink carrier, and receives downlink data from the second downlink carrier.

A communication device includes a receiving circuit, an uplink control information generating circuit, a transmitting circuit and a control circuit. The receiving circuit is configured to operably receive an uplink-downlink (UL-DL) reconfiguration message from a communication station. The uplink control information generating circuit is configured to operably generate a plurality of uplink control information (UCI). The transmitting circuit is configured to operably transmit the UCI in a plurality of data frames, and each of the data frames includes a plurality of subframes. The control circuit is configured to operably determine the communication device to operate in one or more UL-DL configurations of a first UCI configuration set according to the UL-DL reconfiguration message. The UL-DL configurations are grouped into at least the first UCI configuration set and a second UCI configuration set and the first UCI configuration set and the second UCI configuration set include different UL-DL configurations.

In a multicarrier communication system having a plurality of subchannels, a method and apparatus for supporting at least two applications. For example, the method includes associating at least a first application in a set of currently active applications with a first latency path, allocating at least one subchannel to the first latency path, and in response to a change in the set of currently active applications, allocating the at least one subchannel to a second latency path associated with a second application in the set of currently active applications and different from the first latency path.
摘要:
Methods and apparatuses are provided for wireless communication. Control symbols are mapped to a plurality of resource element groups (REGs) which is not assigned to a physical channel format indication channel (PCFICH) or a physical hybrid automatic repeat request indicator channel (PHICH). The REGs are allocated based on a time first manner. The mapped control symbols are transmitted on a packet dedicated control channel (PDCCH). A number of a plurality of resource elements (REs) in each of the REGs depends on an index of an orthogonal frequency division multiplexing (OFDM) symbol and a number of configured reference signals.
摘要:
Information is communicated between access points to cause a recipient access point to invoke an action. In some aspects, a mapping is defined between: 1) sets of physical layer identifiers and/or associated time offsets; and 2) different types of information. The mapping information is provided to access points in a wireless communication system such that an access point can use this scheme to communicate specified types of information to another access point. Based on the mapping, an access point that receives a set of physical layer identifiers from another access point is able to determine the type of information being communicated. The recipient access point may then invoke a specific action based on the type of information that was communicated.
摘要:
A method of wireless communication manages the positioning of uplink pilot channel transmissions. A random access request is transmitted at a first location indicated in a circuit switched fall back (CSFB) redirection message. The random access request is then retransmitted at a second location when a response is not received for the random access request transmitted at the first location.

The REGs are allocated in a time first manner. The mapped control symbols are transmitted on a packet dedicated control channel (PDCCH). Each of the REGs in a first orthogonal frequency division multiplexing (OFDM) symbol of a first slot in a subframe comprises two resource elements (REs) for transmission of a cell-specific reference signal and four REs for transmission of a control signal.
