    摘要: In an orthogonal frequency division multiple access (OFDMA) system including at least one base station and at least one wireless transmit/receive unit (WTRU), sub-carriers are allocated for data transmissions to multiple access WTRUs, where sub-carriers are allocated according to a consecutive sub-carrier allocation (CSA) type and a distributed sub-carrier allocation (DSA) type. Pilot signals with distributed pilot sub-carriers are transmitted and measured at each WTRU to obtain a channel quality metric for each pilot sub-carrier. Each WTRU sends feedback to the base station reporting channel quality based on the measured channel quality metrics. An allocation type is selected and adaptively switched according to channel variations in time and frequency domain.

    摘要: A method and apparatus may be used for peer-to-peer communications. A first non-access point (non-AP) station (STA) may receive a message for establishing a direct communication link from a second non-AP STA. The message may include a service priority. The first non-AP STA may transmit another message in response to receiving the message from the second non-AP STA, and communicate directly with the second non-AP STA. The system may be an Ad hoc network comprising a plurality of STAs without an access point (AP) where each STA maintains a database of one-hop and two-hop STAs, and establishes a direct link to other STAs after informing neighboring STAs of an intention to establish a direct communication link.

    摘要: Method and system for reducing battery consumption during an active session wherein an access point (AP) transmits a wireless transmit/receive unit (WTRU) a packet information regarding packets in a queue waiting for transmission to the WTRU and when the packets are to be decoded, whereby enabling the WTRU to enter or remain in an OFF mode in accordance with the packet information. The AP does not send the packets to the WTRU until the AP informs the WTRU about the packet.

    摘要: The present invention is a method and apparatus for resource allocation signaling for grouping user real time services. Uplink signaling for voice activity reporting of each user's transition between an active state and an inactive voice state is sent from a wireless transmit/receive unit to a Node B. Radio resource allocation to users of a wireless communication system varies based on user measurement reporting, a pre-determined pattern such as frequency hopping, or a pseudorandom function. Grouping methods are adjusted to better utilize the voice activity factor, so that statistical multiplexing can be used to more efficiently utilize physical resources.

    摘要: A receiver sends hybrid automatic repeat request (H-ARQ) feedback for a current packet and at least one previous packet, whereby an error is detected based on the H-ARQ feedback. The receiver sends H-ARQ feedback with an identification of the packet or a sequence number of a packet that the receiver expects to receive next. The receiver stores a packet in a memory before combining the packet with a previously received packet, and decodes the stored packet after failing to decode a combined packet to avoid a corruption error. The receiver may set a timer when sending a NACK. If the receiver fails to receive a packet until expiration of the timer, the receiver initiates a process for recovering the packet. Each H-ARQ feedback may be associated with other attributes. Some H-ARQ processes may operate in an asynchronous mode while others in a synchronous mode in the same direction.
