Abstract

Solutions are disclosed that provide intelligent adaptive measurement gaps for low mobility user equipment (UEs), such as home internet access points. Because low mobility (stationary use) UE do not move, or move only infrequently, the frequency for of handovers to neighboring cells is reduced, lowering the urgency of measuring signal reception from neighboring cells. A wireless network determines that a first UE is associated with a stationary use, and that a second UE is not. The network transmits a first radio resource control (RRC) message specifying a measurement gap repetition period (MGRP) and an indication to skip at least one measurement gap, to the first UE, and transmits a second RRC message specifying the MGRP, without an indication to skip a measurement gap, to the second UE. In some examples, the MGRP is indicated as having one of four values: 20 milliseconds (ms), 40 ms, 80 ms, and 160 ms.

First claim

What is claimed is:

1 . A method of wireless communication, the method comprising:
determining, by a wireless network, that a first user equipment (UE) is associated with a stationary use; determining, by the wireless network, that a second UE is not associated with the stationary use; based on at least determining that the first UE is associated with the stationary use, transmitting, to the first UE, a first radio resource control (RRC) message specifying a measurement gap repetition period (MGRP) and an indication to skip at least one measurement gap; and based on at least determining that the second UE is not associated with the stationary use, transmitting, to the second UE, a second RRC message specifying the MGRP and not including an indication to skip a measurement gap.

2 . The method of claim 1 , wherein the first UE comprises an internet access point and/or the stationary use includes facility internet access.

3 . The method of claim 1 , wherein the first RRC message and the second RRC message each comprises an RRCReconfiguration message, and wherein the MGRP is within a MeasGapConfig information element of each RRCReconfiguration message.

4 . The method of claim 3 , wherein the indication to skip at least one measurement gap is within the MeasGapConfig information element of the first RRC message.

5 . The method of claim 1 , wherein the MGRP is indicated as having a value selected from the list consisting of:
20 milliseconds (ms), 40 ms, 80 ms, and 160 ms.

6 . The method of claim 1 , wherein the indication to skip at least one measurement gap comprises an integer value.

7 . The method of claim 6 , wherein, with the integer value identified as N, the first UE skips all measurement gaps except one in a set of N or (N+1) consecutive MGRPs.

8 . The method of claim 6 , wherein, with the integer value identified as N, the first UE skips all measurement gaps except one in a set of 2{circumflex over ( )}N consecutive MGRPs.

9 . A system comprising:
a processor; and a computer-readable medium storing instructions that are operative upon execution by the processor to:
determine, by a wireless network, that a first user equipment (UE) is associated with a stationary use;
determine, by the wireless network, that a second UE is not associated with the stationary use;
based on at least determining that the first UE is associated with the stationary use, transmit, to the first UE, a first radio resource control (RRC) message specifying a measurement gap repetition period (MGRP) and an indication to skip at least one measurement gap; and
based on at least determining that the second UE is not associated with the stationary use, transmit, to the second UE, a second RRC message specifying the MGRP and not including an indication to skip a measurement gap.

10 . The system of claim 9 , wherein the first UE comprises an internet access point and/or the stationary use includes facility internet access.

11 . The system of claim 9 , wherein the first RRC message and the second RRC message each comprises an RRCReconfiguration message, and wherein the MGRP is within a MeasGapConfig information element of each RRCReconfiguration message.

12 . The system of claim 11 , wherein the indication to skip at least one measurement gap is within the MeasGapConfig information element of the first RRC message.

13 . The system of claim 9 , wherein the MGRP is indicated as having a value selected from the list consisting of:
20 milliseconds (ms), 40 ms, 80 ms, and 160 ms.

14 . The system of claim 9 , wherein the indication to skip at least one measurement gap comprises an integer value.

15 . The system of claim 14 , wherein, with the integer value identified as N, the first UE skips all measurement gaps except one in a set of N or (N+1) consecutive MGRPs.

16 . The system of claim 14 , wherein, with the integer value identified as N, the first UE skips all measurement gaps except one in a set of 2{circumflex over ( )}N consecutive MGRPs.

17 . One or more computer storage devices having computer-executable instructions stored thereon, which, upon execution by a computer, cause the computer to perform operations comprising:
determining, by a wireless network, that a first user equipment (UE) is associated with a stationary use; determining, by the wireless network, that a second UE is not associated with the stationary use; based on at least determining that the first UE is associated with the stationary use, transmitting, to the first UE, a first radio resource control (RRC) message specifying a measurement gap repetition period (MGRP) and an indication to skip at least one measurement gap, wherein the first RRC message comprises a first RRCReconfiguration message, wherein the MGRP is within a MeasGapConfig information element of the first RRCReconfiguration message, wherein the indication to skip at least one measurement gap is within the MeasGapConfig information element of the first RRC message, wherein the indication to skip at least one measurement gap comprises an integer value, and wherein the MGRP is indicated as having a value selected from the list consisting of:
20 milliseconds (ms), 40 ms, 80 ms, and 160 ms; and
based on at least determining that the second UE is not associated with the stationary use, transmitting, to the second UE, a second RRCReconfiguration message specifying the MGRP and not including an indication to skip a measurement gap.

18 . The one or more computer storage devices of claim 17 ,
wherein the first UE comprises an internet access point; wherein the second UE comprises a cellular telephone; the stationary use includes facility internet access; and wherein the stationary use includes does not include a mobile internet access hotspot.

19 . The one or more computer storage devices of claim 17 , wherein, with the integer value identified as N, the first UE either:
skips all measurement gaps except one in a set of N or (N+1) consecutive MGRPs; or skips all measurement gaps except one in a set of 2{circumflex over ( )}N consecutive MGRPs.

20 . The one or more computer storage devices of claim 17 , wherein the MeasGapConfig information element of the first RRCReconfiguration message is within a MeasConfig information element of the first RRCReconfiguration message.
