Abstract:
1. A method, comprising: a radio access network (RAN) receiving a power headroom report from a wireless communication device (WCD); the RAN determining that transmission time interval (TTI) bundling is warranted for the WCD based on at least the power headroom report; in response to determining that TTI bundling is warranted for the WCD, the RAN selecting a TTI bundle size, N, for the WCD from among at least three values based on at least a utilization of an uplink shared channel, the at least three values including N=2, N=3, and N=4, wherein the RAN selecting the TTI bundle size, N, for the WCD based on at least a utilization of an uplink shared channel comprises: if the utilization of the uplink shared channel is in a low range, selecting the TTI bundle size of N=4; if the utilization of the uplink shared channel is in a medium range, selecting the TTI bundle size of N=3; and if the utilization of the uplink shared channel is in a high range, selecting the TTI bundle size of N=2; and the RAN instructing the WCD to use the selected TTI bundle size.
