Methods, apparatuses, and computer program products are described for a user equipment in a wireless communication system with a plurality of user equipment where reference weight vectors orthogonal to each other are selected from a predefined set of directions for reference beams. The inner products of a UE-specific beam weight vector with all reference weight vectors is performed and UE-specific beams are mapped to the set of reference beams. From the set of reference beams, based on the reference beam with largest magnitude of inner product, the direction of the user equipment is determined. Based on that determined direction, the user equipment is instructed in to pair with another user equipment of the plurality.

UE-specific beam mapping with reference weight vectors

The method includes determining a minimum number of resource blocks that can be assigned to a user equipment for delay sensitive traffic; determining a maximum number of resource blocks for allocation to data based on a transmit power setting; allocating a number of resource blocks to the uplink data transmission based on the minimum number of resource blocks and the maximum number of resource blocks for segmentation as segmented data; predicting a Signal to Noise+Interference ratio (SINR) based on the allocated number of resource blocks; assigning a modulation and coding scheme (MCS) to a wireless transmission based on the predicted SINR and a threshold MCS; and transmitting scheduling information to the user equipment, the scheduling information including the allocated number of resource blocks and the assigned MCS.

Apparatus, method and computer readable medium for payload segmentation of wireless packet data transmissions

In one embodiment, an apparatus for channel estimation includes a first receiver configured to obtain a first channel estimate associated with a communication channel between the apparatus and a user equipment. The apparatus also includes a second receiver. The second receiver includes a channel estimation unit and a normal receiver processing unit. The channel estimation unit is configured to compute a second channel estimate of channel conditions associated with the communication channel. The normal receiver processing unit is configured to compute weights using the second channel estimation unit. The channel estimation unit is further configured to obtain a delay between the obtaining of the first channel estimate and the computing of the weights, and to compute the second channel estimate using the delay and the first channel estimate.
