摘要： Handover procedures and a collection of new handover MAC management messages are provided for a wireless mobile multi-bop relay (MMR) network. The types of handovers supported include macro diversity handover (MDHO) and fast access station switching (FASS). The handover procedures for these two types of handover and the MAC messages are described for nine main classes of network topologies. The nine classes of topology are further classified into to main categories, namely, intra multi-hop base station (MR-BS), when and where the handover is in the MMR cell, and inter MR-BS handover, when and where the handover is between two different MMR cells.

摘要： A method and system enables and improves performance of hybrid automatic repeat request (HARQ) operations on channels between stations of an orthogonal frequency division multiple access (OFDMA) wireless communication network. There, the number of parallel HARQ channels is increased adaptively, and one connection identifier is used to unambiguously identify a set of MAC protocol data units (MPDUs) communicated over parallel HARQ channels. A sequence number is used to avoid out-of-order MPDU delivery when MPDUs are transmitted over parallel HARQ channels. The MPDUs can be concatenated or encapsulated. The maximum number of the parallel HARQ channels can be increased to 256, and can be negotiated when a station enters or re-enters the network.

摘要： A method performs a hybrid automatic repeat-request (HARQ) operation in a wireless orthogonal frequency division multiple access (OFDMA) network. A quality of a channel between a transmitter and a receiver is estimated as an error metric. A packet for the HARQ operation is fragmented adaptively at the transmitter according to the estimated error metric. The fragmentation is performed at the HARQ layer when the error metric is less than a predetermined threshold, otherwise the fragmentation is performed at the MAC layer.

摘要： A method accesses channels in an OFDMA mobile multihop relay wireless network. The method partitions a downlink sub-frame into at least one downlink access zone and a set of downlink relay zones. The uplink subframe is partitioned into at least one uplink access zone and a set of uplink relay zones. During the downlink access zone, the base station and the relay stations transmit only to the set of mobile stations. During the downlink relay station, the base station and the set of relay stations communicate with each other, while the mobile stations are idle. During the uplink access zone, the set of mobile stations transmit only to the set of relay stations and the base station. During the uplink relay station, the base station and the set of relay stations communicate with each other, while the mobile stations are idle.

摘要： Embodiments of the invention describe a method for antenna selection (AS) in a wireless communication network, the network comprising user equipment (UE), configured to transmit a sounding reference signal (SRS) from a subset of antennas at a time without transmitting user data. The method transmits a first SRS from a first subset of antennas in a first subframe, wherein the first subframe does not include the user data, and transmits a second SRS from a second subset of antennas in a second subframe, wherein the second subframe does not include the user data. After receiving, in response to the transmitting the first SRS and the second SRS, information identifying an optimal subset of antennas from the first subset of antennas and the second subset of antennas, the method selects the optimal set of antennas such that the optimal subset of antennas is selected without transmitting the user data.
