Definitions

  • This disclosure relates to In-Device Coexistence (IDC) problems for a User Equipment (UE) in a communication network.
  • IDC In-Device Coexistence
  • the In-Device Coexistence (IDC) feature was introduced in Long Term Evolution (LTE) and New Radio (NR).
  • LTE Long Term Evolution
  • NR New Radio
  • IDC can arise in user equipments (UEs) that are able to operate according to different radio access technologies (RATs) at the same time.
  • a UE may comprise one or more antennas and circuitry for transmitting and receiving signals according to a Third Generation Partnership Project (3GPP)-standardised RAT, such as Long Term Evolution (LTE) or New Radio (NR), and also one or more antennas and circuitry for transmitting and receiving signals according to WiFi (IEEE 802.11) or Bluetooth (BT). Since these antennas and circuitry are effectively collocated in the UE, it is possible for transmissions/receptions of signals on one of the RATs to interfere with the transmissions/reception of signals on another one of the RATs that are taking place at the same time. This interference can be referred to as in-device coexistence (IDC) interference.
  • IDC in-device coexistence
  • the IDC feature was introduced to address situations where a UE is operating using multiple radio technologies and the radios used for these different technologies cause interference to each other.
  • An example is shown in Fig. 1 Error! Reference source not found.where radio frequency (RF) transmissions by an LTE transmitter is causing interference to a Global Positioning System (GPS) receiver and a Bluetooth (BT)/Wide Local Area Network (WLAN) receiver, as well as RF transmissions by the Bluetooth/WLAN transmitter causing interference to the LTE receiver.
  • GPS Global Positioning System
  • BT Bluetooth
  • WLAN Wide Area Network
  • the IDC feature is here described using LTE as an example of a Third Generation Partnership Project (3GPP) Radio Access Technology (RAT), but on a high level, the IDC feature is the same for NR.
  • 3GPP Third Generation Partnership Project
  • RAT Third Generation Partnership Project
  • the UE When the UE identifies that there is IDC type of interference, the UE shall first try to solve the problems internally. If this does not succeed, the UE can indicate to the eNB (the base station or radio access network (RAN) node in LTE) that it experiences IDC problems which it cannot solve itself. It should be noted that how the UE detects IDC problems is left to implementation. The indication from the UE to the eNB that it is experiencing, or expects to experience, IDC problems that it cannot resolve itself is referred to herein as an "IDC indication”.
  • IDC indication The indication from the UE to the eNB that it is experiencing, or expects to experience, IDC problems that it cannot resolve itself.
  • IDC feature is useful is when the UE is using an LTE carrier in band 40 at the same time as it is using WLAN in the 2.4 GHz band. There may be IDC problems in this scenario since these frequency bands are just next to each other, as shown in Fig. 2. Error! Reference source not found. The UE would then try to solve the problems internally (e.g. by adjusting or changing the operation of LTE or WLAN), but if it cannot do so it will indicate to the eNB that the serving cell on band 40 is having an IDC problem, and the eNB can then handover the UE to another frequency or reconfigure the cell.
  • a UE may be configured with a DRX configuration in connected mode to save battery.
  • DRX is configured, the UE is only required to monitor the Physical Downlink Control Channel (PDCCH) when the UE is in "Active Time”, but when the UE is not in Active Time, the UE can skip PDCCH monitoring and hence save power.
  • PDCCH Physical Downlink Control Channel
  • the network would want to continue to schedule the UE for a while.
  • the network would then have to wait until the UE wakes up (i.e. until the next onDuration) and then the network can start sending data to the UE.
  • the onDuration is short, the network may not be able to complete the data transfer to the UE.
  • the drx- InactivityTimer (or just "inactivity timer” or similar) is used. The inactivity timer is started by the UE each time the UE is scheduled (i.e.
  • the UE receives a grant to send uplink (UL) data after it sends a Scheduling Request (SR), or UE receives downlink assignment because the network (NW) wants to send downlink (DL) data). So, even if the onDuration would be short, the UE starts the inactivity timer if it gets scheduled, and hence the UE will stay in Active Time as long as the UE keeps on getting scheduled.
  • SR Scheduling Request
  • NW Network
  • a UE configured with the DRX can be configured with both a long and a short DRX cycle.
  • the intention with the long DRX cycle is that the UE should be able to sleep a long time between waking up, while with a short DRX cycle the UE wakes up more frequently.
  • These time periods that the UE is awake to listen for scheduling requests is called OnDuration periods, and is configured for a certain time duration that the UE shall be awake.
  • the UE first drops into a short DRX cycle, where the UE is still relatively quickly reachable, but if there is not traffic for some time, the UE drops into the long DRX cycle.
  • the UE will start applying long DRX cycles.
  • secondary DRX it has been proposed to introduce so-called secondary DRX.
  • the UE has two different values for the drx-lnactivityTimer and two different values for the onDuration timers.
  • the UE would, for one set of cells, apply a first drx-lnactivityTimer value and a first onDuration timer value, while for another set of cells, apply a second drx-lnactivityTimer value and a first onDuration timer value.
  • the UE has two Medium Access Control (MAC) entities and each MAC entity has its own DRX operation.
  • MAC Medium Access Control
  • the UE would have two DRX processes per MAC entity, i.e. in total four DRX processes/procedures.
  • the UE may indicate to the network information about IDC problems that the UE cannot solve by itself.
  • the UE may indicate a TDM indication which says that the IDC problems can be addressed by a TDM pattern, e.g. a DRX pattern.
  • the network may, in response to such an indication, configure a DRX configuration that the UE applies and that addresses the UE's IDC problems.
  • the DRX configuration will apply to all carriers and hence also impacts carriers which do not experience IDC issues/problems. If the UE applies that DRX pattern to unaffected cells it means those carriers cannot be used for communication during the time that the UE is not in Active Time according to the DRX pattern. That wastes resources and will reduce the times when the UE can communicate with the network, hence also reducing user experience, since throughput will be limited.
  • the network can configure a DRX configuration for the UE that does not apply to all communication resources (e.g. carriers), and instead it applies only to a subset of the communication resources (e.g. carriers). That subset contains the problematic communication resources (e.g. carriers), but not all communication resources (e.g. carriers).

  • Communication resources may be indicated in terms of carriers, cells, bandwidth parts (BWPs), frequency/frequencies or frequency range(s), PRB range(s), etc.
  • the network can configure a DRX configuration applicable to a subset of the communications resources, including at least the indicated set of communication resources, but not to all communications resources.
  • a network would configure one DRX configuration applicable to all communication resources of the UE for a particular RAT, e.g. LTE or NR. If instead, as per this first set of embodiments, a DRX configuration is only configured for the communication resources of a particular RAT that the UE indicated the IDC issues for (or some additional, but not all other, communications resources), the rest of the communication resources for that RAT can be used as normal. It should be noted that the network may still configure another DRX configuration for the rest of the communication resources, but that other DRX configuration does not need to consider the IDC issues and hence may not need to be as restrictive (e.g. it does not need to include a DRX sleep time for the times when the UE is experiencing IDC issues).

  • One example of such an indication is an indication of whether the UE supports a "secondary DRX feature”.
  • the secondary DRX feature was defined in 3GPP Release 16 of NR, and allows the UE to have independent DRX configurations for two sets of serving cells, i.e. one DRX pattern (or no DRX pattern) associated to a first set of cells, and another DRX pattern (or no DRX pattern) associated to a second set of cells.
  • the network can determine whether the communications resources with the IDC issues (that can be addressed in a TDM manner) can share a DRX configuration or not. For example, if the UE indicated that serving cell A and serving cell B have IDC issues which can be addressed by a TDM indication, the network would determine if serving cell A and B can share a DRX configuration or not. This may be determined based on whether serving cell A and B are in the same frequency range. If they can share a DRX configuration, the network may configure a DRX configuration applicable to those two cells, but the DRX configuration is not applicable to (all) other cells.
  • Embodiment family 2 is a diagrammatic representation of Embodiment family 2
  • the UE indicates IDC indications per group of carriers, and may provide (multiple) relevant TDM configurations. Further details of this approach is provided below.
  • a UE sends a first IDC indication to the network for a first set of carriers, and a second IDC indication to the network for a second set of carriers.
  • the IDC indications may be TDM indications or FDM indications.
  • the UE may send two TDM indications, one for a first set of carriers and one for the second set of carriers.
  • the first indication may be a TDM indication
  • the second indication may be an FDM indication.
  • the first IDC indication and the second IDC indication may be sent in the same message. This would reduce latency of sending the IDC indications, and would reduce signalling overhead.
  • the first IDC indication may be sent in a first message and the second IDC indication in a second message.
  • the UE may in this case indicate a relation between the first IDC indication and the second IDC indication. This relation may be so that when sending the second IDC indication the UE indicates with an indication that the previously sent first IDC indication still applies.
  • no explicit indication that the previously sent first indication applies may be included in the message, but instead the network assumes that the first IDC indication applies until the UE has explicitly indicated that the first IDC indication no longer applies, e.g. by means of an indication that the first IDC indication is cancelled or can be ignored.
  • the UE can first send a message with the first IDC indication, and later send a message with both the first IDC indication and later the second IDC indication.
  • This has the benefit that if initially the UE only experiences IDC issues on the first set of carriers (which are indicated to the network), and later starts experiencing IDC issues also on the second set of carriers, each message contains the complete information relevant at the point of sending the messages. Compare, for example, to a situation where if the second message only contains the second IDC indication, it would not be clear if the first IDC indication is still relevant if the first IDC indication is not present in the second message.
  • the UE can determine the first set of carriers to be carriers in a first frequency range (e.g. one of Frequency Range 1 (FR1) and Frequency Range 2 (FR2)), and the second set of carriers to be carriers in a second frequency range (e.g. the other one of FR1 and FR2).
  • a benefit of this approach is that it is well-defined (e.g. by a specification) which carriers/frequencies an IDC indication applies to, without a need for additional signalling. It is not, however, as flexible as some other approaches (for example as described below).
  • the network can indicate the carriers belonging to the first set and the second set.
  • the indication may be an indication in a Radio Resource Control (RRC) message.
  • RRC Radio Resource Control
  • the network may indicate a flag for a carrier to indicate which set the carrier belongs to.
  • the indication may have a numerical value, e.g. 0 to indicate the first set, and 1 to indicate the second set.
  • Another approach is that if a flag is present for a carrier it means that the carrier belongs to the second set, but if absent it means that the carrier belongs to the first set.
  • the UE decides which carriers belong to the first and second set of carriers.
  • the UE can indicate, for an IDC indication, which carriers the IDC indication applies to.
  • the UE may send a first IDC indication and indicate that the IDC indication applies to carriers C1 and C3, and a second IDC indication that applies to carriers C2 and C4.
  • the UE may indicate the applicable carriers by referring to an index associated with the carrier, such as a serving cell index.
  • the network receiving the indication may configure a first DRX configuration for the first set of carriers.
  • the first set of carriers may be part of a defined range of carriers, e.g. Frequency Range 1 (FR1) carriers or Frequency Range 2 (FR2) carriers, and the network may configure a DRX configuration that is applied to all of the carriers in that defined range, i.e. all Frequency Range 1 (FR1) carriers or all Frequency Range 2 (FR2) carriers.
  • FR1 Frequency Range 1
  • FR2 Frequency Range 2
  • the DRX configuration will be applied to the carriers in the defined range that are experiencing IDC issues, and to the other carriers in the defined range that are not experiencing IDC issues.
  • the network may also configure a second DRX configuration for the second set of carriers, and where the second set of carriers are only some of the carriers in a defined range of carriers (e.g. part of FR1 or FR2), the UE will apply the DRX configuration to the second set of carriers and also some additional (unaffected) carriers in the defined range that are not experiencing IDC issues.
  • a defined range of carriers e.g. part of FR1 or FR2
  • Whether the UE sends two IDC indications as described above or not may be configured by the network.
  • the network may, for example, configure the UE to do so only if the network is able to configure secondary DRX patterns for the UE. If the network has not enabled the feature of secondary DRX, it would not configure a UE to send two DRX patterns as IDC indications. Alternatively, even if the network does support secondary DRX, if a particular UE is not capable of secondary DRX the network may refrain from configuring the UE with two DRX patterns as the network does not support two different DRX patterns anyway.
  • DRX pattern A is the DRX pattern that the UE is configured with first.
  • DRX pattern B is the DRX pattern the UE wants in order to address the IDC issues. It can be seen there is an offset in the Active Time instances and frequency of on-durations in the two configurations.
  • the UE may require Pattern B in order to address the IDC problem, and the UE would hence send information to the network which the network can use to change the DRX configuration from Pattern A to Pattern B.
