First Claim
Patent Images
1. A method comprising:
- receiving an input that includes a required maximum capacity for sounding or discovery and a maximum tolerated latency for a service group comprising one or more apparatuses being configured to use half-duplex wireless device-to-device communication;
selecting a pattern group from a set of pattern groups based on the received input; and
configuring physical resources for the half-duplex wireless device-to-device communication to the service group to have, for sounding or discovery within the service group, one or more patterns in the selected pattern group, the one or more patterns defining for the physical resources, a number of serial resources, a number of parallel resources, and a number of transmission phases.

9. An apparatus comprising at least one processor;
- and one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to;
receive an input that includes a required maximum capacity for sounding or discovery and a maximum tolerated latency for a service group comprising one or more apparatuses being configured to use half-duplex wireless device-to-device communication; select a pattern group from a set of pattern groups based on the received input; and configure physical resources for the half-duplex wireless device-to-device communication to the service group to have, for sounding or discovery within the service group, one or more patterns in the selected pattern group, the one or more patterns defining for the physical resources, a number of serial resources, a number of parallel resources, and a number of transmission phases.
- and one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to;

10. A system supporting a multi-apparatus environment and comprising:
-
at least two apparatuses, a first apparatus and a second apparatus, belonging to a service group and being configured to use half-duplex wireless device-to-device communication; at least the first apparatus being configured to; receive an input that includes a required maximum capacity for sounding or discovery and a maximum tolerated latency for the service group; calculate a number of patterns in a pattern group for a set of pattern groups, the set starting from a pattern group comprising one serial resource and having one transmission phase and ending to a pattern group comprising an amount of serial resources corresponding to the maximum tolerated latency and having at most as many transmission phases as parallel resources; calculate a number of parallel resources in the pattern group for the pattern groups; calculate total number of resources in the pattern group for the pattern groups; select amongst the pattern groups one pattern group whose number of patterns provide the required maximum capacity for sounding or discovery with a minimum total number of resources; determine the number of parallel resources, the number of serial resources, the number of patterns and the number of transmission phases in said selected one pattern group using calculation results; and create patterns for sounding or discovery of the service group using the determined number of parallel resources, the determined number of serial resources, the determined number of patterns and the determined number of transmission phases; and at least the second apparatus configured to; receive an input that includes a value of a required capacity for sounding or discovery for a service group that comprises the one or more apparatuses configured to use half-duplex wireless device-to-device communication; select, from the patterns created for sounding or discovery, one or more patterns based on the value of the required capacity; and configure a physical channel providing the half-duplex wireless device-to-device communication to the service group to have the selected one or more patterns for sounding or discovery for the service group. - View Dependent Claims (11, 12, 13)
