Abstract: A base station maps code blocks of a transport block of a transport block size (TBS) for a channel using tone-level interleaving or resource element (RE)-level interleaving. Then, the base station can transmit the code blocks of the transport block of the TBS for the channel. A UE may receive the channel from the base station and de-interleave the received tones of the channel in a frequency domain to obtain the code blocks of the transport block having the TBS for the channel.

Abstract: Certain aspects of the present disclosure generally relate to randomization of positioning reference signal (PRS) frequency offsets and muting patterns in long term evolution (LTE) for enhanced observed time difference of arrival (eOTDOA). According to certain aspects, a method is provided for wireless communications which may be performed, for example, by a base station (BS). The method generally includes randomly selecting at least one parameter used to determine a set of time-frequency resources for transmitting positioning reference signals (PRS) and transmitting PRS on the determined set of time-frequency resources. The user equipment (UE) may randomly select the at least one parameter used to determine the set of time-frequency resources to measure for the PRS from the BS and measure PRS on the determined set of time-frequency resources.

Abstract: When a user equipment engaged in mobile communications transfers from a network with one radio access technology (RAT) to another network with a different radio access technology, maintaining continuity of location based services can improve system performance. A user equipment may perform a series of checks when undergoing inter-RAT transfer to determine if a location based services protocol used with the source network is operable on the target network. The UE also determines if location based services sessions are at a point where they can be continued following inter-RAT transfer. Where possible, protocols and sessions are maintained to preserve location based services continuity.
