Abstract: Methods for preventing timing collisions in a wireless communication network include transmitting a data uplink symbol of normal duration via a first base pair using a first timing advance (TA) corresponding to the first base pair. Scheduling to transmit a second uplink symbol via a second base pair (BP) corresponding to the transmit RF chain. Predicting a timing collision will occur based on a different between the first TA and a second TA corresponding to the second BP. Preventing the timing collision by: reducing the duration of the second symbol by an adjustment amount calculated based on the first TA and the second TA; inserting a guard interval to delay transmission of the second symbol by the calculated adjustment amount; and increasing the duration of a cyclic prefix of the second symbol but refraining from transmitting a portion of the enlarged CP.

Abstract: Reliable detection of the configuration of transmit antennas includes obtaining a data for transmission, encoding the data, and modulating the data. During the modulating of the data, the data may be configured in such a way as to convey the configuration of the antennas through the modulation of the data. An antenna configuration is obtained by obtaining a representation of the antenna configuration, and masking the data with an error correcting code, where the mask corresponds to the antenna configuration.

Abstract: Asynchronous Hybrid Automatic Repeat reQuest (ARQ) process identities are transmitted in a wireless communication system. A linking scheme is established between at least two sets of process identities of two respective corresponding codewords. When a first process identity is selected from among a first set of process identities of a first codeword, a second process identity may be derived in dependence upon the first process identity and the established linking scheme. Finally, a first packet from the first codeword is transmitted using a first transmission channel indicated by the first process identity, and a second packet is transmitted from the second codeword using a second transmission channel indicated by the second process identity. In addition, a control message including only the first process identity is transmitted.

Abstract: A transmitted signal estimate based on signals received in a layer i within a multiple input, multiple output transmission system and based upon selected constellation points for other, previously processed layers is quantized to a nearest constellation point. A list of candidates headed by the nearest constellation point and with remaining candidates presorted by proximity to the head is selected, for each such quantized estimate based on constellation point selections for previously processed layers. To select K best candidates for the transmitted signal estimates of the current layer i, the proximity of the candidates at the head of each list to the signal estimate for the current layer are compared, and the closest candidate is selected. The list containing the selected candidate is advanced, and proximity of the transmitted signal estimate to all list heads is again evaluated and the closest candidate selected.
