Abstract: Multiple antennas at the transmitter and receiver increase the capacity in a wireless communication system. Received signal quality can be enhanced through diversity by transmitting the same symbol on multiple antennas. Data rate can be increased through multiplexing by transmitting different symbols on the transmitting antennas. Operating in one particular mode only is generally not suitable. Choosing diversity or multiplexing by taking into account the location of a user can enhance both throughput and reliability.

Abstract: A communication device includes a decoder that sequentially decodes sub-packets of a first packet that contain redundant traffic information. The decoder identifies a first sequence location where it successfully decoded one of the sub-packets of the first packet to output the traffic information. The decoder then sequentially decodes sub-packets of a second packet starting at a second sequence location that is determined in response to the first sequence location. Related methods, user equipment node, and radio access network nodes are also disclosed.

Abstract: Upon receiving a particular data unit by a receiving layer of a wireless device, it is detected that a previous data unit earlier in sequence to the particular data unit has not yet been received by the receiving layer. A timer is started in response to the detecting, where the timer has a time-out period that is variable dependent upon a parameter associated with receipt of the particular data unit. Upon expiration of the timer based on the timeout period, the receiving layer generates an error indication.

Abstract: A mobile terminal can receive N or less different data streams transmitted in parallel over N antennas. The number of different data streams actually transmitted in parallel to the mobile terminal corresponds to transmission rank. If the speed of the mobile terminal does not exceed a predetermined threshold, the mobile terminal utilizes a full-size codebook containing precoder elements for all N transmission ranks to determine a recommended transmission rank and precoder matrix for use in transmitting data to the mobile terminal. Otherwise, the mobile terminal utilizes a reduced-size codebook which excludes the precoder elements for at least transmission rank-N to determine the recommended transmission rank and precoder matrix where transmission rank-N corresponds to N different data streams being transmitted in parallel over the N antennas. The mobile terminal transmits an indication of the recommended transmission rank and precoder matrix to the network.

Abstract: A method to increase spectral efficiency in a communication system is described herein. The communication system includes at least one mobile station and is capable of transmitting messages encoded according to a plurality of available modulation coding schemes (“MCSs”). Each available MCS includes a modulation scheme and an effective coding rate. The MCSs are indexed according to increasing complexity. A signal-to-interference ratio (“SINR”) is determined which is sufficient to satisfy a predetermined frame error rate (“FER”). A first MCS and a corresponding amount of transmissions needed to satisfy the predetermined FER at the SINR using the first MCS are determined. The first MCS has a higher effective coding rate than a second MCS. The second MCS sufficiently satisfies the predetermined FER at the SINR in a single transmission. A message encoded according to the first MCS is transmitted through the communication system using hybrid automatic repeat request (“HARQ”).

Abstract: A method providing communications for a wireless terminal in a wireless communication network may include providing communications for the wireless terminal from a first antenna array for a first base station sector. Responsive to receiving an entry notification that the wireless terminal has entered a border area between the first base station sector and a second base station sector, a load in the second base station sector may be compared with a load threshold. Responsive to the load in the second base station sector being less than the load threshold, multipoint communications may be provided for the wireless terminal through the first antenna array for the first base station sector and through a second antenna array for the second base station sector. Responsive to the load in the second base station sector being greater than the load threshold, multipoint communications may be blocked for the wireless terminal.

Abstract: A MIMO (Multiple-Input-Multiple-Output) receiver may receive a plurality of MIMO transport blocks transmitted from a plurality of MIMO transmission antennas over a same carrier frequency. More particularly, a MIMO signal including the plurality of MIMO transport blocks may be received through a plurality of reception antennas, and respective measures of signal quality for each of the MIMO transport blocks may be computed. A MIMO transport block may be selected from the plurality of MIMO transport blocks based on the measures of signal quality, and the selected MIMO transport block may be decoded. Responsive to failure decoding the selected MIMO transport block, processing of all MIMO transport blocks received in the MIMO signal may be terminated. Related communication devices are also discussed.
