  • Patent number: 8873522
    Abstract: In a wireless communication system, user equipment (UE) is provided, one or more set of rules are provided for the UE to handle the processing during a measurement gap. In some aspects, the gap measurement may be ignored. In some aspects, the processing is stored and handled at a later in time and gap measurements are performed. Depending on the system, the measurements performed during the gaps may be UE implementation dependent, wherein the UE determines whether to perform the measurement for a given gap. In some instances, the UE may not perform measurements during the gap, thereby giving priority to other processing, such as RACH processing. Depending on the type of processing required (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.

  • Patent number: 8861487
    Abstract: Open loop power control in Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) multi-carrier systems is facilitated through the determination of a value for open loop control on a primary carrier frequency which is then used to perform open loop control on at least one secondary carrier frequency in the multi-carrier system. This determined open loop control value may be applied using the value determined on the primary carrier frequency, or may be further adjusted using an estimated difference between received power of the primary carrier frequency and the secondary carrier frequencies, in selected aspects. When the pilot signals in the secondary carrier frequencies are transmitted at different power levels, this open loop control value may be further adjusted with a transmit power level offset.

  • Patent number: 8817711
    Abstract: A UE receives a HS-PDSCH transmission from a base station and concurrently performs rate matching on systematic bits and parity bits (parity 1 bits, parity 2 bits) of the received HS-PDSCH transmission. The systematic bits and parity bits are buffered in a CPC circular buffer to support HARQ processing in a HS-SCCH-less operation of the base station. Memory locations are computed for the systematic bits and the parity bits according to corresponding transmission parameters such as, for example, redundancy version, number of systematic bits and/or number of physical channels. The systematic bits and the parity bits are stored in the corresponding computed memory locations of the CPC circular buffer. At least a portion of the stored systematic bits and parity bits are concurrently generated based on corresponding transmission parameters from the CPC circular buffer per request to support concurrent rate matching on systematic bits and parity bits.
