Abstract: Multiple input multiple output (MIMO) communication systems and methods for chip to chip and intrachip communication are disclosed. In one aspect, MIMO techniques that have been applied to wireless communication systems are applied to interchip and intrachip communication systems. In particular, a transfer function is applied at the transmitter, and a reverse transfer function is applied at the receiver. The transfer function dynamically changes based on channel conditions to cancel or otherwise mitigate electromagnetic interference (EMI) and crosstalk conditions. In an exemplary aspect, a sum of power levels across the channels may have a maximum. To abide by such power level constraint, the transfer function may be optimized to reduce interference while remaining within the power level constraint.

Abstract: A mobile wireless device may dynamically alter a downlink MIMO function by switching it on and off, or switching between different downlink MIMO configurations, such as 2×MIMO and 4×MIMO. Still further, a mobile device having greater than two antennas may dynamically select a subset of the antennas to be used to receive a MIMO transmission, and further, enable a mobile device to request a subset of antennas at a base station to be used for the MIMO transmission. This dynamic control of the MIMO mode or configuration may be achieved by using implicit signaling, by way of an enlarged code word set in CQI feedback transmissions, or by using explicit signaling, by way of E-DPCCH orders. In this way, a MIMO-capable mobile device may dynamically be configured for downlink MIMO transmissions as the conditions demand, enabling MIMO to be switched off when its use might otherwise cause performance to suffer.

Abstract: In aspects of the present disclosure, a user equipment receives inter-NodeB multi-point transmissions, and a multipoint aggregation component detects a gap in the sequence numbers, delays transmitting a not acknowledged signal (NAK) by starting a NAK delay timer, and transmits, by a transceiver, NAK for the gap in sequence numbers in response to the NAK delay timer expiring and detecting that the gap has not been filled during the delaying. If the Medium Access Control (MAC) entity as the respective NodeB identifies itself to the Radio Link Control (RLC), out-of-order delivery (skew) can eventually be distinguished from genuine data loss before the NAK delay timer expires based upon tracking the highest sequence numbers received. Adaptive NAK delay timer can be performed by monitoring skew duration.
