Methods and systems for using a load metric based on time and variance of using RF resources to select an RF coverage area

摘要

Aspects of selecting a base station or coverage area for a UE device are described. The UE device or a wireless network component (e.g., a base station) can determine RF uplink use values of a coverage area sector or cell. The RF uplink use values can be received from one or more base stations and can be based on a subframe or other time segment. The UE device can determine an average and variation of the RF uplink use values, and a load metric. The load metric can indicate a load pattern of an RF uplink. A selection of the base station or coverage area can be based on the load metric and whether the UE device is located or operating at an edge of a cell or coverage area. The UE device, while idle, can continue or switch to camping on the selected base station or coverage area.

1. A method comprising:
determining, by at least one processor, a first set of multiple wireless uplink sub-frame use values (WUSUV), wherein each WUSUV of the first set corresponds to a separate transmission segment of a first time period, wherein the first time period comprises multiple separate transmission segments, wherein each WUSUV of the first set represents a count of how many different uplink resource blocks for a coverage area provided by a first base station are used or available during the separate transmission segment corresponding to that WUSUV, and wherein the first base station provides multiple different uplink resource blocks for the coverage area; determining, by the at least one processor, a variance of the first set of multiple WUSUV, wherein the variance of the first set of multiple WUSUV represents a variance of the counts of how many different uplink resource blocks for the coverage area provided by the first base station are used or available during the separate transmission segments of the first time period; determining, by the at least one processor, an average of the first set of multiple WUSUV, wherein the average of the first set of multiple WUSUV represents an average of the counts of how many different uplink resource blocks for the coverage area provided by the first base station are used or available during the separate transmission segments of the first time period; determining, by the at least one processor, a first load metric, based on, at least in part, the variance of the first set of multiple WUSUV and the average of the first set of multiple WUSUV; and transmitting, by a transmitter using a wireless downlink, at least one of the first load metric and a selection the at least one processor makes based on, at least in part, the first load metric.
