摘要： Methods and apparatus are described for providing compatible mapping for backhaul control channels, frequency first mapping of control channel elements (CCEs) to avoid relay-physical control format indicator channel (R-PCFICH) and a tree based relay resource allocation to minimize the resource allocation map bits. Methods and apparatus (e.g., relay node (RN)/evolved Node-B (eNB)) for mapping of the Un downlink (DL) control signals, Un DL positive acknowledgement (ACK)/negative acknowledgement (NACK), and/or relay-physical downlink control channel (R-PDCCH) (or similar) in the eNB to RN (Un interface) DL direction are described. This includes time/frequency mapping of abovementioned control signals into resource blocks (RBs) of multimedia broadcast multicast services (MBMS) single frequency network (MBSFN)-reserved sub-frames in the RN cell and encoding procedures for these. Also described are methods and apparatus for optimizing signaling overheads by avoiding R-PCFICH and minimizing bits needs for resource allocation.

摘要： A method and apparatus for controlling transmit power in a wireless local area network (WLAN). For example, a station may receive, from an access point (AP), a beacon frame that includes a field indicating a maximum transmission power for at least one of a plurality of operational bandwidth that the AP supports. The station may determine a transmission power for a signal to be transmitted to the AP based on the at least one of the plurality of operational bandwidths indicated in the received beacon. The station may then transmit the signal at the determined transmission power.

摘要： An access point includes a transmitter configured to transmit signals, a receiver configured to receive signals, and a timing information device. The timing information device is configured to receive a timing information request from a station associated to the access point, receive timing information for a beacon signal sent by a second access point, and report the timing information to the station. The timing information includes a time difference relative to a known reference time for transmission of the beacon signal and the time difference is an offset in timing units.

The WTRU further includes a baseband processor operatively coupled to the receiver, the baseband processor and the receiver configured to not monitor the plurality of control channels in time intervals outside the first pattern of time intervals. The receiver is configured to receive a downlink shared channel transmission from the wireless network. The baseband processor is operatively coupled to a transmitter, and the baseband processor and the transmitter are configured to transmit an indication of an outcome of a decoding attempt of the downlink shared channel transmission a fixed number of timeslots after transmission of the downlink shared channel transmission. The indication may be transmitted on an uplink control channel.

摘要： A method and wireless multi-cell communication system for providing high speed downlink packet access (HSDPA) services. The system may include a radio network controller (RNC) in communication with a plurality of base stations. A control signal may be sent to at least one base station having a plurality of timeslots, e.g., in a time division duplex (TDD) system and/or frames including transmission timing intervals (TTIs), e.g., in a frequency division duplex (FDD) system assigned thereto for the establishment of HSDPA channels. The control signal indicates a maximum allowed HSDPA transmit power for each of the timeslots and/or TTIs. The base station sends a feedback signal to the RNC indicating the results of measurements of the power of the transmitted HSDPA timeslots and/or TTIs during a predetermined time period.
