Description

Technical Field

[0001] The present disclosure relates generally to wireless communications and more particularly to multiplexing radio resources in a shared spectrum. Background Art

[0002] In wireless communication networks such as 5G New Radio (NR) networks, communication technology is committed to providing higher transmission rates, massive links, ultra-low latency, higher transmission reliability, and 100 times more power efficiency to support the evolving communication needs. In the case where uplink transmissions with different transmission priorities exist simultaneously in a cell, communication technology uses uplink (UL) inter-UE multiplexing to ensure the transmission performance of uplink transmissions with higher transmission priorities. However, when uplink transmissions are performed in shared spectrum (also known as unlicensed spectrum), UL inter-UE multiplexing does not ensure that uplink transmissions with higher transmission priorities will preempt the corresponding transmission resources. Summary of the invention

[0013] The techniques and examples of implementations and / or embodiments in the present disclosure may be used to improve performance in wireless communication systems. The term "exemplary" is used to mean "an example of..." and does not imply an ideal or preferred example, implementation, or embodiment unless otherwise specified. However, please note that implementations may be embodied in a variety of different forms, and therefore, the subject matter covered or claimed is intended to be interpreted as not limited to any embodiment to be described below. Please also note that implementations may be embodied as methods, devices, components, or systems. Therefore, the embodiments of the present disclosure may, for example, take the form of hardware, software, firmware, or any combination thereof.

[0014] A radio access network provides a network connection between a user device and an information or data network such as a voice or video communication network, the Internet, etc. An example radio access network may be based on a cellular technology which may also be based on, for example, 5GNR technology and / or formats. Figure 1 An example system diagram of a wireless communication network 100 including UEs 102 and 124 and a wireless access network node (WANN) 104 according to various embodiments is shown. UEs 102 and 124 may include, but are not limited to, mobile phones, smart phones, tablet computers, laptop computers, smart electronic devices or appliances including air conditioners, televisions, refrigerators, ovens, etc., or other devices capable of wireless communication over a network. Taking UE 102 as an example, it may include a transceiver circuit 106 coupled to an antenna 108 to implement wireless communication with the wireless access network node 104. The transceiver circuit 106 may also be coupled to a processor 110, which may also be coupled to a memory 112 or other storage device. The memory 112 may store therein instructions or codes that, when read and executed by the processor 110, cause the processor 110 to implement the various methods described herein.

[0015] Similarly, the radio access network node 104 may include a base station or other wireless network access point capable of wirelessly communicating with one or more UEs through a network. For example, the radio access network node 104 may include a 5G NR base station, a 5G central unit base station, or a 5G distributed unit base station. Each type of these radio access network nodes may be configured to perform a corresponding set of wireless network functions. The wireless network function sets between different types of radio access network nodes may not be the same. However, the wireless network function sets between different types of radio access network nodes may overlap in function. The radio access network node 104 may include a transceiver circuit 114 coupled to an antenna 116, which may include an antenna tower 118 in various ways to enable wireless communication with the UE 102. The transceiver circuit 114 may also be coupled to one or more processors 120, which may also be coupled to a memory 122 or other storage device. The memory 122 may store instructions or codes therein, which, when read and executed by the processor 120, cause the processor 120 to implement the various methods described herein.

[0016] For simplicity and clarity, only one WANN and two UEs are shown in the wireless communication network 100. It should be understood that there may be one or more WANNs in the wireless communication network, and each WANN may serve one or more UEs at the same time. In addition to UEs and WANNs, the network 100 may also include any other network nodes with different functions, such as network nodes in the core network of the wireless communication network 100. In addition, although various embodiments will be discussed in the context of a specific example wireless communication network 100, the basic principles are applicable to other applicable wireless communication networks.

[0017] Uplink inter-UE multiplexing may include two implementation mechanisms: uplink cancellation and uplink power control, which will refer to Figure 2 and Figure 3 Give a description.

[0018] Figure 2 1 shows a typical application scenario of the uplink cancellation mechanism. For example, UE 102 has an uplink transmission request for ultra-reliable low-latency communication (URLLC), and UE 124 has an uplink transmission request for enhanced mobile broadband (eMBB) communication. URLLC transmission has a higher priority than eMBB transmission. Figure 2 As shown, UE 102 transmits a scheduling request 2 (SR2) to WANN 104. Upon receiving SR2 for URLLC transmission, WANN 104 needs to schedule uplink transmission resources for transmission in a timely manner and allocate the scheduled resources to UE 102 via UL Grant 2. Figure 2As shown, some target transmission resources scheduled for UE 102 have been allocated to UE 124 for eMBB transmission via UL Grant 1. To ensure timely transmission of URLLC, the UL cancellation mechanism utilizes an uplink cancellation indication (UL CL) to cancel eMBB transmission on the target transmission resources. The lower priority uplink transmission that can be canceled can also include a sounding reference signal (SRS).

[0019] Figure 3 A typical application scenario of the uplink power control mechanism is shown. Similarly, UE 102 has an uplink transmission request for URLLC, and UE 124 has an uplink transmission request for eMBB communication. The target transmission resources scheduled for UE 102 partially overlap with the target transmission resources scheduled for UE 124. Therefore, the uplink power control mechanism introduces an open-loop power control parameter set indication field in the UL grant corresponding to the URLLC transmission scheduling, which instructs UE 102 to enhance the transmission power for URLLC transmission to ensure transmission performance.

[0020] Wireless communication systems such as 5G can use shared spectrum (also known as unlicensed bands) as potential working spectrum resources. Network devices (UE, WANN) working on shared spectrum require access to the transmission channel in a listen-before-talk (LBT) manner, also known as channel sensing or channel detection. In other words, network devices first need to detect the channel and only occupy the channel for transmission when the channel access conditions are met.

[0021] In the shared spectrum, UL multiplexing between UEs does not work well as expected. Specifically, under the UL cancellation mechanism, although the lower priority uplink transmission is cancelled according to the UL CL indication, there is still a risk that the higher priority uplink transmission fails to preempt the target transmission resources. This runs counter to the original intention of sacrificing the lower priority transmission to ensure the higher priority transmission. Under the UL power control mechanism, the lower priority uplink transmission will not be cancelled in the case of resource conflict between two uplink transmissions. At the same time, due to the LBT requirement, the UE must perform channel detection before uplink transmission. In the case of a lower priority uplink transmission occurring on the target resource channel, the UE detects that the target resource channel is not idle and does not meet the channel access conditions. As a result, the UE cannot perform a higher priority uplink transmission on the target resource channel.

[0022] One of the objectives of the present disclosure is to improve multiplexing among UL UEs to increase the possibility of higher priority uplink transmissions preempting target resources in a shared spectrum.

[0023] Figure 4An exemplary implementation 400 for multiplexing radio resources is shown. At step 410, UE 102 may obtain a resource scheduling message for uplink transmission from WANN 104. As an example, the resource scheduling message may be an uplink grant and include an identification of scheduled transmission resources and transmission parameters. The scheduled transmission resources may belong to a shared radio frequency transmission band. The transmission parameters may include, for example, a downlink control information (DCI) type, a priority indicator, a ChannelAccess-CPext-CAP, a cancellation indication field, an uplink transmission channel indicator, and other applicable data and fields indicating the priority of the uplink transmission, which will be exemplified later.

[0024] At step 420, UE 102 may determine a channel detection mechanism based on the transmission parameters. The channel detection mechanism may include type 1 channel detection or type 2 channel detection.

[0025] As an example, type 1 channel detection can be a random backoff channel detection, where the backoff number is randomly selected according to a predetermined rule. Whenever a channel detection is performed, if the channel is idle, the backoff value will be reduced by one. When the backoff value is equal to zero, the condition for occupying the channel is met. Type 1 channel detection can be predetermined, indicated in radio resource control (RRC) signaling, or indicated in downlink control information (e.g., uplink grant).

[0026] In contrast, when the UE 102 can access the channel in a shared manner, type 2 channel detection can be used. The shared manner can mean that the UE 102 can occupy the target transmission resource within the shared resource acquired by other devices such as the UE or the WANN by performing a simplified channel such as type 2 channel detection. In some embodiments, type 2 channel detection can include performing a channel detection for a specified duration, such as a channel detection for a duration of 25 μs and a channel detection for a duration of 16 μs. The length of the duration can be predefined or configured by the WANN 104. Alternatively, type 2 channel detection can include not performing channel detection.

[0027] In some implementations, the transmission parameter may be a DCI type field defined in an uplink grant received from WANN 104. For example, in the case where the value of the DCI type field is 1, UE 102 may select type 2 channel detection to occupy the scheduled transmission resources. In the case where the value of the DCI type field is 0, UE 102 may select type 1 channel detection to occupy the scheduled transmission resources.

[0028] Alternatively or additionally, the transmission parameter may be a cancellation indication field, included in the uplink grant, indicating whether the scheduled uplink transmission involves canceling another uplink transmission. If the currently scheduled uplink transmission resources are vacated by canceling other uplink transmission traffic, the UE 102 may select type 2 channel detection to occupy the scheduled transmission resources. Otherwise, the UE 102 may select type 1 channel detection to occupy the scheduled transmission resources.

[0029] Alternatively or additionally, the transmission parameter may be a priority indication field in an uplink grant received from WANN 104. In the case where the field indicates that the uplink transmission has a higher transmission priority, UE 102 may select type 2 channel detection to occupy the scheduled transmission resources. Otherwise, UE 102 may select type 1 channel detection to occupy the scheduled transmission resources.

[0030] Alternatively or additionally, the transmission parameter may be a ChannelAccess-CPext-CAP field in an uplink grant received from WAN 104. In the case where the LBT type indicated in this field belongs to simplified channel detection, UE 102 may select type 2 channel detection to occupy the scheduled transmission resources. Otherwise, UE 102 may select type 1 channel detection to occupy the scheduled transmission resources.

[0031] Alternatively or additionally, the transmission parameter may be an uplink transmission resource indication field, which indicates the time domain resources scheduled for uplink transmission and / or the frequency domain resources scheduled for uplink transmission, and the UE determines whether the transmission resources scheduled in the uplink grant fall within a channel occupied time (COT) region. The COT region may represent Figure 5 The time-frequency resources occupied by the WANN 104 within a shared radio frequency transmission band are shown.

[0032] UE 102 may obtain uplink transmission resources by sharing the downlink transmission resources of WANN 104. Specifically, WANN 104 may occupy a transmission channel in a shared radio frequency transmission band after performing a designated channel detection and satisfying a predetermined channel access condition. The resource range of the occupied transmission channel is referred to as COT. Figure 5 As shown, WANN 104 can simply use a portion of the transmission resources in the COT for its downlink transmission, so the remaining transmission resources can be shared with UEs served by WANN 104, including UE 102. As an example, the range of the COT can be represented by DCI format 2_0, which includes information on the COT duration and the set of available resource blocks (RBs) contained in the COT.

[0033] For example, COT is described above in the context of a wireless access network node such as WANN 104. It should be understood that the COT region may also represent the time-frequency resources occupied by another UE in the shared spectrum band. Thus, UE 102 may obtain uplink transmission resources by sharing the spare transmission resources of another UE.

[0034] In the case that the transmission channel scheduled for uplink transmission of UE 102 falls within the COT region, UE 102 may choose to occupy the scheduled transmission resources in Type 2 channel detection. Otherwise, UE 102 may choose to occupy the scheduled transmission resources in Type 1 channel detection.

[0035] Various transmission parameters are discussed above for determining the type of channel detection to occupy the scheduled transmission resources. It should be understood that these transmission parameters can also be used in combination to serve this function. For example, UE 102 can select type 2 channel detection to occupy the scheduled transmission resources only when the scheduled transmission resources fall within the COT area and the priority indicator indicates that the uplink transmission has a higher priority.

[0036] Alternatively or additionally, in case that the multiplexing among UL UEs operates under the UL power control mechanism, the transmission parameters may include a power control indicator indicating whether uplink transmission is performed with improved transmission power due to resource multiplexing with UL transmission.

[0037] As an example, the power control indicator may be an open-loop power control parameter set indication (OLPI) field in the uplink grant. Specifically, when the OLPI field indicates that the open-loop power control parameter is from an open-loop power control parameter set list configured in the RRC parameter P0-PUSCH-Set (which indicates that uplink transmission is to be performed with improved transmission power), the UE 102 may select type 2 channel detection to occupy the scheduled transmission resources. Otherwise, the UE 102 may select type 1 channel detection to occupy the scheduled transmission resources.

[0038] Typically, WANN 104 can use RRC parameters P0-PUSCH-Set and P0-PUSCH-AlphaSet to configure two open-loop power control parameter set lists. P0-PUSCH-Set includes one or more P0 values, which are suitable for configuring open-loop power control parameters for multiplexing between UL UEs, that is, multiplexing with resources of other UL transmissions. P0-PUSCH-AlphaSet includes one or more groups of {P0,alpha} values, which are suitable for configuring open-loop power control parameters for multiplexing between non-UL UEs. Both P0 and α can be used to determine the open-loop power control parameters of the transmission power. P0 represents the target received power and α represents the compensation coefficient of the transmission path loss. The OLPI field is used to indicate which open-loop power control parameter set list will be selected to determine the transmission power of the uplink transmission traffic.

[0039] return Figure 1 At step 430, UE 102 may detect the scheduled transmission resources using the detection mechanism determined at step 420. If it is detected that the scheduled transmission resources satisfy the channel access condition, UE 102 may occupy the scheduled transmission resources to perform uplink transmission.

[0040] In some embodiments, in the case where multiplexing between UL UEs applied to a shared radio frequency transmission band operates under a UL power control mechanism, the WAN 104 can configure two power detection thresholds, power_threshold_1 and power_threshold_2, for the UE 102. The power_threshold_2 is higher than the power_threshold_1. The UE 102 can determine which power detection threshold to use in channel detection for uplink transmission based on, for example, the OLPI field in the uplink grant that schedules the uplink transmission.

[0041] Specifically, when the OLPI field indicates that the open-loop power control parameter is from the open-loop power control parameter set list configured in the RRC parameter P0-PUSCH-Set (which means that the uplink transmission will be performed with the improved transmission power due to resource multiplexing with other UL transmissions), the UE 102 can use a higher power threshold, namely power_threshold_2, to detect the ongoing transmission on the scheduled transmission resources. In this way, although the scheduled transmission resources are being used for transmission traffic, if the transmission power of the transmission traffic is lower than power_threshold_2, the UE 102 can determine that the scheduled transmission resources are not occupied and are eligible to perform uplink transmission on the scheduled transmission resources. On the contrary, if the UE 102 determines that the uplink transmission is performed without improving the transmission power, it can use power_threshold_1 to detect the ongoing transmission on the scheduled transmission resources.

[0042] Various methods may be used to configure the two power detection thresholds. For example, WANN 104 may configure two parameters, Threshold (e.g., maxEnergyDetectionThreshold-r14) and Threshold offset (e.g., energyDetectionThresholdOffset-r14), through RRC signaling. power_threshold_1 is equal to Threshold, and power_threshold_2 is equal to Threshold plus Threshold offset.

[0043] Alternatively, the WANN 104 may configure only the parameter Threshold offset (eg, energyDetectionThresholdOffset-r14) through RRC signaling. power_threshold_1 may be calculated according to a predetermined equation. power_threshold_2 may be equal to Threshold offset plus power_threshold_1.

[0044] Alternatively, the WANN 104 may configure the parameter Threshold offset (e.g., energyDetectionThresholdOffset-r14) through RRC signaling. power_threshold_2 may be equal to Threshold offset plus power_threshold_1. If the WANN 104 further configures the parameter Threshold (e.g., maxEnergyDetectionThreshold-r14), power_threshold_1 may be equal to Threshold. Otherwise, power_threshold_1 may be calculated according to a predetermined equation.

[0045] Alternatively, the WANN 104 may configure the parameter energyDetectionThresholdOffset via DCI. power_threshold_2 may be equal to energyDetectionThresholdOffset plus power_threshold_1. If the WANN 104 further configures the parameter Threshold (e.g., maxEnergyDetectionThreshold-r14) via RRC signaling, power_threshold_1 may be equal to Threshold. Otherwise, power_threshold_1 may be calculated according to a predetermined equation.

[0046] Alternatively, the WANN 104 may configure the value of power_threshold_2 through DCI. If the WANN 104 configures the parameter Threshold (eg, maxEnergyDetectionThreshold-r14) through RRC signaling, power_threshold_1 may be equal to Threshold. Otherwise, power_threshold_1 may be calculated according to a predetermined equation.

[0047] Optionally, before determining at step 420 that the channel detection mechanism occupies the scheduled transmission resource selected between type 2 channel detection and type 1 channel detection, UE 102 may determine whether the scheduled transmission resource has a transmission from another wireless communication system or cell. If UE 102 determines that the scheduled transmission resource is transmitting traffic for the other wireless communication system or cell, UE 102 may directly select type 1 channel detection to occupy the scheduled transmission resource. Otherwise, UE 102 may determine the channel detection mechanism based on the transmission parameters, as described above with reference to Figure 4 As discussed in step 420 of .

[0048] Other wireless communication systems or cells may refer to wireless communication networks that utilize different communication technologies or standards than the wireless communication network 100. The UE 102 may determine, for example, whether traffic from other systems or cells is being transmitted using target resources by checking a pattern specified for transmission resource mapping. Traffic from a system or cell typically uses the same pattern, for example, avoiding mapping data to a specific resource element (RE). Thus, the UE 102 may detect the transmission power of a specific RE. When the detected transmission power is higher than a predefined threshold, the UE 102 may determine the presence of heterogeneous system or cell traffic.

[0049] Optionally, UE 102 may transmit channel occupancy information to WANN 104. The channel occupancy information may indicate whether UE 102 can preempt the target transmission resource. The target transmission resource may be pre-configured to UE 102 by WANN 104, for example, via RRC signaling, DCI, or a medium access control element (MAC CE).

[0050] In some implementations, channel occupancy information may be indicated in a scheduling request (SR). For example, two SR sequences are defined, SR sequence 1 and SR sequence 2. SR sequence 1 may indicate that the UE 102 is able to preempt the target resource. SR sequence 2 may indicate that the UE 102 is unable to preempt the target resource, or is uncertain whether it is able to preempt the target resource. The UE 102 may transmit the corresponding SR sequence as the channel occupancy information.

[0051] Alternatively, two SR frequency domain positions are defined. For example, SR spectrum position 1 may indicate that UE 102 is able to preempt the target resource. SR spectrum position 2 may indicate that UE 102 is unable to preempt the target resource, or is uncertain whether it is able to preempt the target resource. UE 102 may transmit the corresponding SR frequency position as channel occupancy information.

[0052] Alternatively, two SR time domain positions are defined. For example, SR time domain position 1 may indicate that UE 102 can preempt the target resource. SR time domain position 2 may indicate that UE 102 cannot preempt the target resource, or is uncertain whether it can preempt the target resource. UE 102 may transmit the corresponding SR time domain position as channel occupancy information.

[0053] Alternatively, two SR time-frequency domain positions are defined. For example, SR time-frequency domain position 1 may indicate that UE 102 is able to preempt the target resource. SR time-frequency domain position 2 may indicate that UE 102 is unable to preempt the target resource, or is uncertain whether it is able to preempt the target resource. UE 102 may transmit the corresponding SR time-frequency domain position as channel occupancy information.

[0054] Alternatively, it may be specified that as long as the UE 102 transmits a SR, it indicates that the UE 102 is able to preempt the target resource.

[0055] When the channel occupancy information indicates that UE 102 can seize the target resource, WANN 104 may transmit uplink grant 1 to UE 102 to provide transmission parameters for uplink transmission using the target resource. Optionally, uplink grant 1 may not include at least one of a time domain resource allocation indication field and a frequency domain resource allocation indication field.

[0056] Optionally, in the case where the target resource is allocated to an uplink transmission with a lower transmission priority, WANN 104 can transmit UL C1 to cancel the transmission of the lower priority traffic on the target resource. Alternatively, WANN 104 can instruct UE 102 to increase the transmission power of its uplink transmission in uplink grant 1.

[0057] When the channel occupancy information indicates that UE 102 cannot preempt the target resource, WANN 104 may transmit uplink grant 2 to allocate new transmission resources for uplink transmission of UE 102 .

[0058] Various embodiments are discussed above to implement multiplexing between UL UEs in a shared spectrum. Multiple conditions are defined for the UE to determine whether it can share the transmission resources of other network devices (such as UEs and WANNs). When the defined conditions are met, the UE can occupy the target transmission channel in a shared manner for its high-priority uplink transmission, which increases the possibility that the high-priority uplink transmission can preempt the target transmission channel. In this way, although the low-priority uplink transmission is cancelled, the risk that the high-priority uplink transmission cannot occupy the target transmission channel due to failure to compete for transmission resources is reduced. Therefore, the overall resource efficiency of the network system and the transmission reliability for high-priority traffic can be guaranteed.
