Description

RADIO ACCESS TECHNOLOGY COEXISTENCE TECHNIQUES BACKGROUND
[0001] In some wireless networks, user equipment (UE) may be capable of supporting multiple wireless technologies concurrently. UEs, for example, may include both Third Generation Partnership Project (3 GPP) Long Term Evolved (LTE) and WiFi Radio Access Technologies (RAT) to allow communication over either LTE or WiFi, or both LTE and WiFi concurrently. UEs that support both LTE and WiFi communication may use the advantages of both RATs to increase the speed of communication while decreasing the cost and amount of power used to transfer data.
[0002] However, in-device coexistence issues may occur when UEs communicate over LTE and WiFi concurrently. The transmission on an LTE frequency band may cause interference with reception on a WiFi frequency band at the UE.
Likewise, transmission on a WiFi frequency band may cause interference with reception on an LTE frequency band at the UE. Thus, a desire exists for a solution to provide functionality and protocols scalable and efficient to meet the constraints for
communication using multiple wireless technologies concurrently.

EXAMPLE EMBODIMENTS
[0010] An initial overview of technology embodiments is provided below and then specific technology embodiments are described in further detail later. This initial summary is intended to aid readers in understanding the technology more quickly but is not intended to identify key features or essential features of the technology nor is it intended to limit the scope of the claimed subject matter.
[0011] In one aspect, wireless multi-connectivity enables User Equipment (UE) to send and receive data on two or more wireless networks. For example, the UE may be used to provide voice communications over an LTE network, while also sending and receiving text, pictures, video or the like over a WLAN network using the same device. In addition, the bandwidth of two or more wireless networks may be aggregated to provide greater bandwidth. However, the simultaneous transmission and reception on two or more wireless networks may cause in-device co-existence issues. For example, the transmission of LTE data packets from a UE can cause interference with the reception of WLAN data packets at the UE. Likewise, the transmission of WLAN data packets from the UE can cause interference with the reception of LTE data packets at the UE.
[0012] In one aspect, the present technology provides for a time sharing mechanism for two or more different Radio Access Networks (RAN). In one aspect, concurrent use of two different RANs is identified. The time sharing mechanism is activated in response to identification of the concurrent use. Once activated, the different RANs are operated in accordance with the time sharing mechanism
[0013] FIG. 1 depicts a wireless multi-connectivity system, in accordance with an example. In one aspect, the multi-connectivity system includes one or more Long Term Evolved (LTE) Evolved NodeBs (eNB) 110, one or more Wireless Local Area
Network Access Point (WLAN-AP) 120, and one or more User Equipment (UE) devices 130. One or more LTE networks communicatively couple eNBs to UEs, and one or more WLAN networks communicatively couple WLAN-APs to UEs. eNBs may also be communicatively coupled to WLAN-APs by one or more additional network connections 140.
[0014] In one instance, the eNBs and UEs may include one or more antennas, one or more 3GPP LTE radios to modulate and/or demodulate signals transmitted or received on an air interface, and one or more 3GPP LTE digital processors to process signals transmitted and received on the air interface. In one instance, the UEs and WLAN-AP may include one or more antennas, one or more WLAN radios to modulate and/or demodulate signals transmitted or received on an air interface, and one or more WLAN digital processors to process signals transmitted and received on the air interface. In one instance the WLAN can be an Institute of Electronics and Electrical Engineers (IEEE) 802.11 network (WiFi). In one instance, the eNBs may be LTE Evolved NodeBs (eNB). In one instance, the WLAN-APs may each include one or more WiFi Access Points (AP). In one instance, the UEs may include one or more smart phones, tablet computing devices, laptop computers, internet of things (IOT) devices, and/or other types of computing devices that provide digital communication including data and/or voice communication.
[0015] An eNB may be a relatively high power node, referred to as a "macro node" or a relatively low power node (LPN). An LPN can include a micro node, pico node, home eNB (HeNB), remote radio head (RRH), remote radio entity (RRE), and the like. The eNB can provide communication coverage for a particular geographic area. The term "cell" can refer to a coverage area of an eNB and/or an eNB subsystem serving this coverage area.
[0016] In one aspect, the LTE and WiFi radios of the UE can enable the UE to simultaneously transmit data over an LTE link while receiving other data over a WiFi link, or simultaneously receive data over the LTE link while transmitting other data over the WiFi link. In one aspect, the multi-connectivity system provides for LTE WLAN aggregation (LWA) (e.g., mobile data offload or "Wi-Fi Offloading"). In LWA, data packets (e.g., packet data units "PDUs") may be served on LTE and Wi-Fi radio links. An advantage of LWA is that it can provide increased control and utilization of resources on both links (e.g., LTE links and Wi-Fi radio links). LWA can be used to increase the aggregate throughput for all users and improve the total system capacity by better managing the radio resources among users. However, when an operating radio frequency (RF) band of the LTE link is relatively close to the operating RF band of the WiFi link, the simultaneous transmission on the LTE link and reception on the WiFi link, and/or simultaneous reception on the LTE link and transmission on the WiFi link may cause interference. The interference may cause in-device coexistence issues for LWA and other multi-mode operations.
[0017] FIG. 2 illustrates functionality of an eNB to facilitate wireless multi- connectivity, in accordance with an example. The functionality of the eNB includes a
WLAN-LTE time sharing mechanism for concurrent use of an LTE service and a WLAN service. The WLAN-LTE time sharing mechanism of the eNB can be implemented by one or more processors and memory, wherein the memory stores one or more sets of instructions, that, when executed by the one or more processors, perform one or more functionalities including the WLAN-LTE time sharing mechanism. In one instance, the WLAN can be an Institute of Electronics and Electrical Engineers (IEEE) 802.1 1 network (WiFi), and the corresponding WLAN-LTE time sharing mechanism may be
implemented by one or more processors and memory of an application circuitry, a baseband circuitry, and/or Radio Frequency (RF) circuitry of the eNB. [0018] In one aspect, the functionality of the eNB can include identifying a
WiFi-LTE concurrent use for one or more UEs 210. In one aspect, the WiFi-LTE concurrent use can be determined by the eNB based upon an operating state of the eNB. In one instance, the eNB can determine that there is concurrent use when the eNB is communicating in an LTE-WLAN Aggregation (LWA) operating mode with a given UE. In one instance, the LWA may be performed using an Institute of Electronics and Electrical Engineers (IEEE) 802.11 ax (WiFi) protocol.
[0019] In another aspect, the WiFi-LTE concurrent use can be identified based upon a message received from the UE that indicates the WiFi-LTE concurrent use. In one instance, the WiFi-LTE concurrent use can be indicated in an In-device Coexistence Indication (InDeviceCoexTimeSharing) message received by the eNB from a given UE. For example, Table 1 illustrates exemplary information conveyed as an
InDeviceCoexTimeSharing message.

The InDeviceCoexTimeSharing message can be used to inform the eNB about the in- device coexistence time sharing parameters. An exemplary implementation of the message may be as shown in Table 2.

Table 2
[0020] In one aspect, the eNB can transmit to the UE a message that indicates the activation of a WiFi-LTE time sharing mechanism 220, in response to the identified WiFi-LTE concurrent use. The message can be transmitted from the eNB to the UE using a higher layer communication, such as a Radio Resource Control (RRC) communication, a Master Information Block (MIB), a Secondary Information Block (SIB), a Packet Data Convergence Protocol (PDCP), or another desired type of higher layer communication.
[0021] In one aspect, the indication of the activation of the WiFi-LTE time sharing mechanism can also include a time sharing period, an LTE active time-length of the time sharing period, an LTE inactive time-length of the time sharing period, and a start of the time sharing period. In one instance, the time sharing period may be 100 milliseconds (ms), and the LTE active and LTE inactive time-lengths may each be 50 ms, or any other appropriate periods and time-lengths, from several milliseconds to hundreds of milliseconds. In another instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each include five (5) 10 ms alternating time- lengths, or any other appropriate periods and time-lengths, from several milliseconds to hundreds of milliseconds.
[0022] In one aspect, the eNB can also transmit to the WLAN AP a message that indicates the activation of the WiFi-LTE time sharing mechanism 230, in response to the identified WiFi-LTE concurrent use. The message can be transmitted from the eNB to the WLAN AP across one or more wired communication links according to an Xw Rel-13 compliant protocol. The message may be transmitted from the eNB to the WLAN AP via one or more routers and or one or more GPT-U endpoints. In one aspect, the indication of the activation of the WiFi-LTE time sharing mechanism can also include the time sharing period, the LTE active time-length of the time sharing period, the LTE inactive time-length of the time sharing period, and the start of the time sharing period. [0023] In one aspect, the LTE active time-length or one or more portions of the LTE active time-length of the time sharing period can be associated with a Discontinuous Reception (DRX) mechanism. In one aspect the UE and eNB can negotiate phases, in which data transfers occur, to correspond to the LTE active time-length of the time sharing period.
[0024] In one aspect, the eNB can transmit to the UE during the LTE active time-length or one or more portions of the LTE active-time length of the time sharing periods 240. Accordingly, communications from the eNB to the UE are timed to the LTE active time-length so that the wireless LTE transmission from the eNB to the UE during the active time-length does not interfere with communications between the WLAN-AP and the UE during the LTE inactive time length of the time sharing periods.
[0025] In one instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each be 50 ms. In such case, the eNB can transmit data on the LTE communication link to the UE during the 50 ms LTE active time-lengths, and does not transmit data on the LTE communication link during the 50 ms LTE inactive time-lengths. In another instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each include five (5) 10 ms alternating time-lengths, or other appropriate periods and time-lengths. In such case, the eNB can transmit data on the LTE communication link to the UE during each 10 ms LTE active time-lengths. In another case, the eNB can transmit data on the LTE
communication link to the given UE during one or more of the five (5) 10 ms portions of the LTE active time-lengths, while data can be transmitted to other UEs on the other 10 ms portions of the LTE active time lengths.
[0026] In one aspect, transmission and reception during the LTE active time- length or one or more portions of the LTE active time-length, of the time sharing period, can be associated with a Discontinuous Reception (DRX) mechanism. During the LTE inactive time length of the time sharing period, the LTE transceiver of the UE can turn off or enter a lower power state.
[0027] FIG. 3 illustrates functionality of a UE to facilitate wireless multi- connectivity, in accordance with an example. The functionality of the UE can include a WLAN-LTE time sharing mechanism for concurrent use of an LTE service and a Wi-Fi service. The WLAN-LTE time sharing mechanism of the UE can be implemented by one or more processors and memory, wherein the memory stores one or more sets of instructions, that, when executed by the one or more processors, perform one or more functionalities including the WLAN- LTE time sharing mechanism. In one instance, the WLAN can be an Institute of Electronics and Electrical Engineers (IEEE) 802.1 1 network (WiFi), and the corresponding WLAN-LTE time sharing mechanism may be
implemented by one or more processors and memory of an application circuitry, a baseband circuitry, and/or Radio Frequency (RF) circuitry of the UE.
[0028] In some implementations of IEEE 802.11 (WiFi), the WLAN-AP provides an indication of when the UE can transmit. In one instance, the WLAN-AP provides a trigger frame, and the UE transmits immediately after the trigger frame.
However, the WLAN-AP is not aware of LTE traffic between the eNB and UE and therefore may send trigger frames during LTE transmission between the eNB and UE. In other implementations of IEEE 802.11 (WiFi), the WLAN-AP may not provide an indication of when the UE can transmit. The UE implements a Listen-Before Transmit (LBT) procedure. If the UE detects traffic, the UE waits a random amount of time before transmitting. However, the predetermined wait or back-off may result in reduced bandwidth utilization, increased latency or similar deleterious effects. Furthermore, LTE transmissions between the eNB and UE occur in real time and change quickly. Therefore, it is difficult to adjust the WiFi transmissions between the WLAN-AP and UE.
[0029] In one aspect, the functionality of the UE can optionally include transmitting a message from the UE to the eNB indicating WiFi-LTE concurrent use 310. The WiFi-LTE concurrent use can be indicated in an In-device Coexistence Indication (InDeviceCoexIndication) message transmitted by the UE to the eNB. The message can be transmitted from the UE to the eNB using a higher layer communication, such as a Radio Resource Control (RRC) communication, a Master Information Block (MIB), a Secondary Information Block (SIB), a Packet Data Convergence Protocol (PDCP), or another desired type of higher layer communication.
[0030] In one aspect, the message that indicates the WiFi-LTE concurrent use can also suggest an LTE active time-length and an LTE inactive time-length of a time sharing period. In one instance, the suggested time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each be 50 ms, or any other appropriate periods and time-lengths. In another instance, the suggested time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each include five (5) 10 ms alternating time-lengths, or any other appropriate periods and time- lengths, as previously described.
[0031] In one instance, the WiFi-LTE concurrent use can be indicated in an In- device Coexistence Indication (InDeviceCoexTimeSharing) message received by the eNB from a given UE. For example, Table 1 illustrates exemplary information conveyed as an InDeviceCoexTimeSharing message. The InDeviceCoexTimeSharing message can be used to inform the eNB about the in-device coexistence time sharing parameters. An exemplary implementation of the message can be as shown in Table 2. [0032] In one aspect, the UE can decode a message from the eNB that indicates activation of a WiFi-LTE time sharing mechanism 320. The message can be received by the UE from the eNB across the wireless communication link according to the LTE compliant protocol. The message can be received by the UE from the eNB using a Radio Resource Control (RRC) layer communication, or another desired higher layer communication, as previously described. The indication of the activation of the WiFi- LTE time sharing mechanism can also include a time sharing period, an LTE active time- length of the time sharing period, an LTE inactive time-length of the time sharing period, and a start of the time sharing period. In one instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each be 50 ms, or any other appropriate periods and time-lengths, as previously described. In another instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time- lengths may each include five (5) 10 ms alternating time-lengths, or any other appropriate periods and time-lengths, as previously described.
[0033] In one aspect, the UE can transmit to the eNB during the LTE active time-length or one or more portions of the LTE active-time length of the time sharing periods 330. Accordingly, communications from the UE to the eNB are timed to the LTE active time-length so that the wireless LTE transmission from the UE to the eNB during the active time-length do not interfere with communications between the UE and the WLAN AP during the LTE inactive time length of the time sharing periods.
[0034] In one instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each be 50 ms. In such case, the UE can transmit data on the LTE communication link to the eNB during the 50 ms LTE active time-lengths, and does not transmit data on the LTE communication link during the 50 ms LTE inactive time-lengths. In another instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each include five (5) 10 ms alternating time-lengths. In such case, the UE can transmit data on the LTE
communication link to the eNB during each 10 ms LTE active time-lengths. In another case, the UE can transmit data on the LTE communication link to the eNB during one or more of the five (5) 10 ms portions of the LTE active time-lengths, while data is transmitted by other UEs on the other 10 ms portions of the LTE active time lengths.
[0035] In one aspect, transmission and reception during the LTE active time- length or one or more portions of the LTE active time-length, of the time sharing period, can be associated with a Discontinuous Reception (DRX) mechanism. During the LTE inactive time length of the time sharing period, the LTE transceiver of the UE can turn off or enter a lower power state.
[0036] In one aspect, the UE can transmit to the WLAN AP during the LTE inactive time-length or one or more portions of the LTE inactive time-length of the WiFi- LTE time sharing period 340. Accordingly, communications from the UE to the WLAN AP can be timed to the LTE inactive time-length so that the wireless WLAN transmission from the UE to the WLAN during the inactive time-length do not interfere with communications between the UE and the eNB during the LTE active time-length of the time sharing periods.
[0037] In one instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each be 50 ms. In such case, the UE can transmit data on the WiFi communication link to the WLAN AP during the 50 ms LTE inactive time-lengths, and does not transmit data on the WiFi communication link during the 50 ms LTE active time-lengths to the eNB. In another instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each include five (5) 10 ms alternating time-lengths. In such case, the UE can transmit data on the WiFi communication link to the WLAN AP during each 10 ms LTE inactive time- lengths. In another case, the UE can transmit data on the WiFi communication link to the WLAN AP during one or more of the five (5) 10 ms portions of the LTE active time- lengths, while data is transmitted from other UEs on the other 10 ms portions of the LTE active time lengths. [0038] In one aspect, the communications between the UE and WLAN AP can be transmitted from the UE to the WLAN AP across one or more wireless communication links according to an IEEE 802.11 (WiFi) compliant protocol. WiFi compliant protocols include 802.11 (1997), 802.11 a (199), 802.11b (1999), 802.1 lg (2003), 802.11η (2009), 802.1 l ac (2013) and 802.11 ad (2012), or future compliant protocols such as 802.11 ax and 802.11 ay.
[0039] FIG. 4 illustrates functionality of a WLAN AP to facilitate wireless multi-connectivity, in accordance with an example. The functionality of the WLAN includes a WLAN-LTE time sharing mechanism for concurrent use of an LTE service and a WLAN service. The WLAN-LTE time sharing mechanism of the WLAN AP can be implemented by one or more processors and memory, wherein the memory stores one or more sets of instructions, that, when executed by the one or more processors, perform one or more functionalities including the WLAN-LTE time sharing mechanism. In one instance, the WLAN can be an Institute of Electronics and Electrical Engineers (IEEE) 802.11 network (WiFi), and the corresponding WLAN-LTE time sharing mechanism may be implemented by one or more processors and memory of an application circuitry, a baseband circuitry, and/or Radio Frequency (RF) circuitry of the WLAN AP.
[0040] In one aspect, the functionality of the WLAN AP can include decoding a message from the eNB that indicates activation of a WiFi-LTE time sharing mechanism 410. The message can be received by the WLAN AP from the eNB across one or more wired communication links according to an Xw compliant protocol. The message can be received by the WLAN AP from the eNB via one or more routers and or one or more GPT-U endpoints.
[0041] In one aspect, the indication of the activation of the WiFi-LTE time sharing mechanism can also include a time sharing period, an LTE active time-length of the time sharing period, an LTE inactive time-length of the time sharing period, and a start of the time sharing period. In one instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each be 50 ms, or any other appropriate periods and time-lengths, as previously described. In another instance, the time sharing period may be 100 ms, or other appropriate periods and time-lengths, and the LTE active and LTE inactive time-lengths may each include five (5) 10 ms alternating time-lengths, or other appropriate periods and time-lengths, as previously described. In one instance, the time sharing period can be associated with the beacon interval of the IEEE 802.11 (WiFi) protocol. The beacon interval is included in a beacon frame transmitted periodically by the WLAN-AP. The beacon interval may be 102 ms.
Therefore, the time sharing period, LTE active and LTE inactive time-lengths, and the start time of the time sharing period may be based upon the beacon interval.
[0042] In one aspect, the WLAN AP can transmit to the UE during the LTE inactive time-length or one or more portions of the LTE inactive time-length of the WiFi- LTE time sharing period 420. Accordingly, communications from the WLAN to the UE can be timed to the LTE inactive time-length so that the wireless WLAN transmission from the WLAN to the UE during the inactive time-length does not interfere with communications between the UE and the eNB during the LTE active time-length of the time sharing periods.
[0043] In one instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each be 50 ms. In such case, the WLAN AP can transmit data on the WiFi communication link to the UE during the 50 ms LTE inactive time-lengths, and does not transmit data on the WiFi communication link during the 50 ms LTE active time-lengths to the eNB. In another instance, the time sharing period may be 100 ms, and the LTE active and LTE inactive time-lengths may each include five (5) 10 ms alternating time-lengths. In such case, the WLAN AP can transmit data on the WiFi communication link to the UE during each 10 ms LTE inactive time- lengths. In another case, the WLAN AP can transmit data on the WiFi communication link to the UE during one or more of the five (5) 10 ms portions of the LTE active time- lengths, while data can be transmitted from to other UEs on the other 10 ms portions of the LTE active time lengths.
[0044] Accordingly, the WiFi-LTE time sharing mechanism advantageously allows both the WLAN AP and the eNB to share in-device air-time in a fair manner that will also provide good performance with external traffic controllers, such as the 802.1 lax AP protocol, that otherwise may not synchronize with real-time in-device coexistence signals between the eNB, UE and WLAN.
[0045] FIG. 5 illustrates signaling in a wireless multi-connectivity system, in accordance with an example. In one aspect, a WiFi-LTE time sharing message can be transmitted 505 by a transceiver circuitry of an eNB 510 and received by a transceiver circuitry of a UE 515. The message may be transmitted from the eNB to the UE using a higher layer communication, such as a Radio Resource Control (RRC) communication, a Master Information Block (MIB), a Secondary Information Block (SIB), a Packet Data Convergence Protocol (PDCP), or another desired type of higher layer communication.

[0071] In one aspect, transmission and reception during the LTE active time- length or one or more portions of the LTE active time-length, of the time sharing period, can be associated with a Discontinuous Reception (DRX) mechanism. During the LTE inactive time length of the time sharing period, the LTE transceiver of the UE can turn off or enter a lower power state.
[0072] In one aspect, the UE can transmit to the WLAN AP during the LTE inactive time-length or one or more portions of the LTE inactive time-length of the WiFi- LTE time sharing period 850.

In one instance, the WiFi-LTE time sharing mechanism may be implemented by one or more processors and memory of an application circuitry, a baseband circuitry, and/or Radio Frequency (RF) circuitry of the WLAN AP.
[0075] In one aspect, the functionality of the WLAN AP can include decoding a message from the UE that indicates activation of a WiFi-LTE time sharing mechanism 910.
