Abstract: The disclosure relates to technology for iterative localization and channel estimation in a communication system. A radio network node detects user location information from user equipment in a geographic region, where the geographic region includes a location cluster having multiple location levels. A location signature profile is formed for each level based on the location signature of a corresponding location level in the cluster, and a filter is generated for each level based on the location signature. Upon application of the filter that matches the location level of the location user information, the channel is estimated and the user location information is updated based on the channel estimation. The process is repeated until the user location information converges with a preselected convergence value.

Abstract: The disclosure relates to a method for decoding a transport block encoded with multiple codeblock segments. User equipment determines whether to decode one of a transport block cyclic redundancy check (CRC) and a codeblock segment CRC based on a speed of user equipment. In response to the speed of the user equipment being greater than a threshold, the user equipment decodes the transport block CRC and generates an acknowledgement (ACK) /non-acknowledgement (NAK). In response to the speed of the UE being less than or equal to the threshold, during a first data transmission, the user equipment decodes the codeblock segment CRC for each of the multiple codeblock segments and generates the ACK/NAK. During a second and latter data transmissions, the user equipment decodes the codeblock segment CRC for each of the multiple codeblock segments that failed in the first data transmission and generates the ACK/NAK.

Abstract: A hybrid combination of analog RF beamforming and digital pre-coding is used to improve signal-to-noise ratio and mitigate interference as between an RF base station and a plurality of wireless receivers within a cell area of the base station. Feedback overhead for beamforming training may be reduced by using indices for identifying the preferred beams of each wireless receiver. Scheduling for channel training may be based on identifying non-colliding ones of the RF beams and assigning these to corresponding wireless receivers which can best use the assigned beams in shared transmission slots.
