The present invention provides methods and apparatuses that can provide measurement of glucose with variable intervals between measurements, allowing more efficient measurement with greater patient safety. A method according to the present invention can comprise measuring the value of an analyte such as glucose at a first time; determining a second time from a patient condition, an environmental condition, or a combination thereof; then measuring the value of the analyte at the second time (where the second time can be expressed as an interval after the first time, an absolute time, or a time indicated when certain patient or environmental conditions, or both, are reached or detected). The second time can be determined, as an example, from a comparison of the analyte value at the first time with a threshold. The interval between the first time and the second time can be related to the difference between the analyte value at the first time and the threshold; e.g., the closer to the threshold, the closer the two measurement times. The invention can be used with automated measurement systems, allowing the system to determine measurement times and automatically make measurements at the determined times, reducing operator interaction and operator error.

A scheme for transmission of control channel information in a compact form intended to support SPS (Semi-Persistent Scheduling) in a wireless communication system. As applied to LTE, the scheme is to indicate a pre-configured UE-specific resource allocation in a Downlink Control Information (DCI) format containing information for multiple UEs in the same PDCCH. In order to avoid increasing the number of blind decodes, the DCI format size may be the same as an existing DCI format. Preferably the size of the new format is the same as that of DCI formats 0 / 1A / 3 / 3A. The number of required bits per UE is minimised by signalling only one of a limited set of DCI messages per UE. The scheme provides a means for re-configuring SPS resources for multiple UEs using a single PDCCH transmission, whilst enabling better support for variable packet sizes and variable intervals between packets than currently defined SPS.

Methods and systems for generating a variable spacing pulse position modulated (VSPPM) signal for transmission across an ultra-wideband communications channel. The variable pulse position modulated spread spectrum signal is created by encoding every M input data bits from an input data stream into a symbol consisting of Nc chips. Each chip is divided into 2M sub-chips and each sub-chip is further divided into Np time slots. A pulse is transmitted for each chip in the symbol. During each chip period, the pulse is placed in the sub-chip corresponding to the binary M-tuple (or symbol) value. A time hopping code sequence consisting of Nc elements with a one-to-one chip association is then applied to each symbol so that the position of each pulse is shifted to the appropriate time slot that corresponds to the time hopping code value.
