Discarding channel state information during discontinuous reception

Abstract

Methods, systems, and apparatus for wireless communications are described. If channel state information (CSI) is configured to be transmitted during an inactive discontinuous reception (DRX) duration, a user equipment (UE) may refrain from transmitting the CSI. The UE may determine that the CSI is configured to be transmitted during an inactive DRX duration based on determining that some or all of the configured time slots for transmitting the CSI occur when the UE is operating in an inactive DRX duration. The UE may transmit feedback information such as an acknowledgment (ACK) regardless of whether the UE discards the CSI.

Technical Field

[0003] The following relates generally to wireless communications, and more particularly to discarding channel state information during discontinuous reception. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems may be able to support communication with multiple users by sharing available system resources (such as time, frequency and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, improved LTE (LTE-A) systems or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may use techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA) or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM).

[0005] A wireless multiple-access communication system may include multiple base stations or network access nodes, each of which simultaneously supports communication for multiple communication devices, which may also be referred to as user equipment (UE). For example, an LTE or NR base station may provide mobile devices with access to the Internet via a wireless network.

[0006] The UE may send control or status information to the base station. For example, the UE may send channel state information (CSI) indicating the quality of communication on the channel. The UE may also send feedback information indicating whether a signal is successfully received at the UE. In some examples, the UE may operate in a discontinuous reception (DRX) mode, in which the UE may be active for one or more durations and inactive for one or more other durations. If the UE operates in an inactive DRX duration, the UE may avoid sending or receiving certain types of information (such as CSI and feedback information) to save power. Summary of the invention

[0007] The described techniques relate to improved methods, systems, devices, and apparatuses that support abandoning or reporting information such as channel state information (CSI) during discontinuous reception (DRX) mode operation. It may be desirable that in some examples, if a user equipment (UE) operates in an inactive DRX duration, the UE sends some type of information (such as feedback information) to a base station, which may present challenges if the feedback information is multiplexed with control information. In general, the described techniques relate to a determination of abandoning transmission of CSI if the UE operates in an inactive DRX duration while supporting transmission of feedback information (such as an acknowledgment (ACK) of a signal received at the UE). For example, the UE may determine whether resources for sending CSI are in a time slot that is in an inactive DRX duration. If so, the UE may abandon transmission of the configuration of the CSI and may send an ACK during the inactive DRX duration. The UE may determine whether resources for sending CSI are in a time slot based on a start symbol or an end symbol or based on some other symbol or multiple symbols of the resource. In some examples, the UE may determine whether a radio resource control (RRC) configured physical uplink control channel (PUCCH) resource allocated for sending CSI is in a time slot that is within an inactive DRX duration. In some examples, the UE may select a new PUCCH resource for sending CSI (e.g., based on an indication of a new PUCCH resource received at the UE), and may determine whether the new PUCCH resource is in a time slot that is within an inactive DRX duration. Such techniques may enable the UE to provide ACK / NACK feedback during DRX operation where CSI may be dropped, and may provide backward compatibility with earlier wireless communication systems.

[0036] A user equipment (UE) may be configured to report channel state information (CSI) to a base station at one or more configured transmission times (e.g., transmission times that may be semi-statically configured via radio resource control (RRC) signaling), and may also be configured to send feedback information, such as an acknowledgment (ACK) or negative acknowledgment (NACK) of a signal received by the UE. In some examples, the UE may be configured for concurrent or simultaneous transmission of CSI and feedback information, in which case the UE may, for example, multiplex the CSI and ACK / NACK on the same resource of a physical uplink control channel (PUCCH), and may send the multiplexed CSI and ACK / NACK within a configured time slot. However, in the context of operating a UE in a discontinuous reception (DRX) mode, such concurrent or simultaneous transmission of CSI and feedback information may create challenges.

[0037] If the UE operates in DRX mode, the UE may switch between an active mode and an inactive low power mode (e.g., periodically), and in the inactive low power mode, the UE may avoid sending or receiving certain types of information. That is, if the UE is in an active DRX duration, the UE may be configured to send and receive information, and if the UE is in an inactive DRX duration, the UE may avoid monitoring a signal from a base station, and may also avoid sending or receiving certain types of information.

[0038] In some examples, if the CSI is configured to be sent during an inactive DRX duration, the UE may be configured to avoid sending the CSI on the PUCCH resources (i.e., abandon the transmission of the CSI). The UE may determine that the CSI is configured to be sent during the inactive DRX duration by determining that some or all of the configured time slots for sending the CSI occur when the UE is operating in the inactive DRX duration. Because the UE may be configured to multiplex the ACK with the CSI, the UE may also unfortunately abandon the transmission of the ACK that should have been sent, which may be undesirable and cause additional performance issues. New techniques for determining whether to send CSI and feedback information (such as ACK / NACK) during the inactive DRX duration are needed to avoid unnecessary abandonment of feedback information, for example to determine whether the CSI can be appropriately abandoned.

[0039] In some examples, when the UE operates in an inactive DRX duration, the UE may be configured to determine whether PUCCH resources allocated for transmission of CSI overlap with physical uplink shared channel (PUSCH) resources allocated to the UE for sending data to a base station. In some examples, if the PUCCH resources overlap with the PUSCH resources, the UE may multiplex the CSI on the PUSCH resources (e.g., "piggyback" the CSI on the PUSCH resources), and send the multiplexed CSI on the PUSCH resources instead of sending the CSI on the original (e.g., RRC configured) PUCCH resources. In some examples, the UE may send the piggybacked CSI on the PUSCH resources even during the DRX inactive period. Similarly, if the UE is configured to multiplex CSI and ACK / NACK information, the UE may determine whether the PUCCH resources allocated for transmission of the multiplexed CSI and ACK / NACK information overlap with the PUSCH resources, and may piggyback the CSI and ACK / NACK information on the PUSCH resources for transmission. In some examples, multiplexing CSI with ACK / NACK may change the PUCCH resources allocated for sending CSI and / or ACK / NACK. In any of such examples, the new PUCCH resources identified by the UE for sending CSI and ACK may be different from the RRC-configured PUCCH resources originally allocated to the UE for sending CSI and ACK. The new PUCCH resources may overlap with the PUSCH resources, or may not overlap with the PUSCH resources.

[0040] In some examples, the wireless communication system may be implemented by multiple layers of functionality. Such layers may include a medium access control (MAC) layer, a physical (PHY) layer, an RRC layer, and other layers. In some examples, the RRC layer may configure PUCCH resources for the UE for sending CSI and ACK, and the PHY layer may be responsible for multiplexing the CSI and ACK on resources for transmission, which may be RRC-configured PUCCH resources, new PUCCH resources, or PUSCH resources. The MAC layer may be responsible for determining whether to abandon the transmission of CSI during DRX operation based on whether the resources to be used to send CSI and ACK are in a time slot within an inactive DRX duration (e.g., at least a portion of the time slot is in a time slot within an inactive DRX duration). However, the MAC layer may not be able to use information about new resources (such as PUSCH resources or new PUCCH resources), which may be used by the PHY layer to multiplex uplink control information (UCI) (such as CSI and ACK / NACK). Therefore, the MAC layer may not be able to determine whether the new resources are in a timeslot within the inactive DRX duration, or whether the new resources overlap with PUSCH resources, and the UE may need to use an alternative method to determine whether to give up transmission of CSI during the inactive DRX duration.

[0041] In some other examples, the UE may determine whether to abandon the transmission of CSI based on whether one or more symbols of the RRC-configured PUCCH resources are in a time slot within the inactive DRX duration. That is, the UE may determine whether to abandon the transmission of CSI based on the original PUCCH resources, which may be configured through RRC signaling, without considering the new PUCCH resources after multiplexing the UCI, and without considering the PUSCH resources. For example, the UE may determine whether one or more symbols (such as the first symbol or the last symbol) of the RRC-configured PUCCH resources for sending CSI are configured to be sent during the inactive DRX duration (e.g., in a portion of the time slot including the inactive DRX duration), or whether the entire time slot falls within (e.g., includes) the inactive DRX duration.

[0042] In some other examples, the UE may determine whether to abandon transmission of CSI based on whether one or more symbols of a new PUCCH resource or PUSCH resource are in a time slot within an inactive DRX duration, in a similar manner as described above with respect to RRC-configured PUCCH resources.

[0043] The technology provided herein improves the efficiency and accuracy of wireless communication systems by enabling a UE to determine whether to send CSI during DRX operation and whether to send feedback information during an inactive DRX duration (even if the UE abandons transmission of CSI). Such technology can achieve backward compatibility with previous wireless communication systems while resolving ambiguity about the transmission of CSI and ACK / NACK feedback during an inactive DRX duration. (For simplicity, in some cases, ACK / NACK feedback may be referred to as ACK in this article.)

[0044] Various aspects of the present disclosure are first described in the context of a wireless communication system. Then, an example wireless communication system, DRX timing, and process flow that implement the discussed techniques are described. Various aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow charts related to discarding channel state information during discontinuous reception.

[0045] Figure 1 An example of a wireless communication system 100 that supports abandoning channel state information during discontinuous reception according to various aspects of the present disclosure is shown. The wireless communication system 100 may include one or more base stations 105 (such as base stations or access nodes), one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (such as mission-critical) communications, low-latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0046] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 support transmission of signals according to one or more radio access technologies.

[0047] UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. UEs 115 may be devices of different forms or with different capabilities. Some example UEs 115 are Figure 1The UE 115 described herein may be capable of communicating with various types of devices such as other UEs 115, base stations 105, or network devices (such as core network nodes, relay devices, or other network devices), such as Figure 1 as shown in .

[0048] The base stations 105 may communicate with the core network 130, or with each other, or both. For example, the base stations 105 may be connected to the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130) via the backhaul links 120 (e.g., via X2, Xn, or other interfaces), or both.

[0049] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base transceiver, a radio base station, an access point, a network node, an access node, a wireless node, a radio transceiver, a node B, an evolved node B (eNodeB, eNB), a next generation node B or a giga node B (any of which may be referred to as a gNB), a home node B, a home evolved node B or other appropriate terms. The wireless communication system 100 may include different types of base stations 105 (such as a macro base station or a small cell base station, a provider network device including a central unit (CU) connected to the core network 130, a relay network device including a mobile terminal (MT) function and a distributed unit (DU) function).

[0050] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a user device, or some other appropriate terminology, where "device" may also refer to a unit, a station, a terminal, or a client, as well as other examples. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, as well as other examples, which may be implemented in various items such as home appliances, vehicles, or meters, as well as other examples.

[0051] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, such as Figure 1as shown in .

[0052] The UE 115 and the base station 105 can communicate with each other wirelessly via one or more communication links 125 through one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources with a defined physical layer structure for supporting the communication link 125. For example, the carrier used for the communication link 125 can include a portion of the radio frequency spectrum band (such as a bandwidth portion (BWP)) that operates according to the physical layer channel for a given radio access technology (such as LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (such as synchronization signals, system information), control signaling for coordinating operations for the carrier, user data or other signaling. The wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with the UE 115. According to the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0053] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (such as in FDD mode) or may be configured to carry both downlink and uplink communications (such as in TDD mode).

[0054] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of determined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base stations 105, UEs 115, or both) may have a hardware configuration that supports communications on a particular carrier bandwidth, or may be configurable to support communications on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base stations 105, UEs 115, or both that support simultaneous communications via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0055] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques (e.g., orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM))). In a system employing MCM techniques, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate for UE 115. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity used for communication with UE 115.

[0056] One or more numerologies for a carrier may be supported, where the numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into BWPs with the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier is active at a given time, and communications for a UE 115 may be limited to the active BWP.

[0057] The time interval for the base station 105 or the UE 115 may be expressed in multiples of a basic time unit, which may refer to, for example, T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can indicate the maximum supported subcarrier spacing, and N f The maximum supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources may be organized according to radio frames, each radio frame having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0058] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a plurality of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a plurality of symbol periods (e.g., depending on the length of a cyclic prefix appended to each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period may contain one or more (e.g., N ) symbol periods. f ) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or the frequency band of operation.

[0059] A subframe, slot, mini-slot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100, and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0060] Physical channels may be multiplexed on a carrier according to various techniques. For example, a physical control channel and a physical data channel may be multiplexed on a downlink carrier using a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (such as a control resource set (CORESET)) for a physical control channel may be defined by a plurality of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (such as CORESETs) may be configured for a group of UEs in UE 115. For example, UE 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. An aggregation level for a control channel candidate may refer to the number of control channel resources (such as control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0061] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots or other types of cells or various combinations thereof). The term "cell" can refer to a logical communication entity used for communication with the base station 105 (e.g., on a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), and others) for distinguishing adjacent cells. In some examples, a cell can also refer to a geographic coverage area 110 or a portion (e.g., a sector) of a geographic coverage area 110 on which a logical communication entity operates. Depending on various factors (e.g., the capabilities of the base station 105), such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell can be or include a building, a subset of a building, or an external space between or overlapping a geographic coverage area 110, as well as other examples.

[0062] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers), and may allow unrestricted access by a UE 115 with a service subscription to a network provider supporting the macro cell. A small cell may be associated with a lower power base station 105 than a macro cell, and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to a UE 115 with a service subscription to a network provider, or may provide restricted access to a UE 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), or a UE 115 associated with a user in a residence or office, and other examples). A base station 105 may support one or more cells, and may also support communications on one or more cells using one or more component carriers.

[0063] In some examples, the base stations 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. For example, the wireless communication system 100 may include a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0064] The wireless communication system 100 can be configured to support ultra-reliable communication or low-delay communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable, low-delay or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-delay or critical functions (such as mission-critical functions). Ultra-reliable communication can include private communication or group communication, and can be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo) or mission-critical data (MCData)). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-delay, mission-critical and ultra-reliable low-delay can be used interchangeably in this article.

[0065] In some examples, UE 115 may also be able to communicate directly with other UE 115 over a device-to-device (D2D) communication link 135 (such as using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105, or otherwise unable to receive transmissions from the base station 105. In some examples, a group of UEs 115 transmitting via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0066] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connection, and other access, routing or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (such as a mobility management entity (MME), access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (such as a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by a base station 105 associated with the core network 130. User IP packets may be transmitted via a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. The operator IP service 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0067] Some base stations 105 may include subcomponents such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with the UE 115 through multiple other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (such as radio heads and ANCs), or combined in a single base station 105.

[0068] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band, since the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may penetrate structures sufficiently for a macro cell to provide service to a UE 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) than transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0069] The wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific and medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices such as base stations 105 and UEs 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations in unlicensed bands can be based on carrier aggregation configurations in conjunction with component carriers operating in licensed bands (such as LAA). Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, as well as other examples.

[0070] The base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas based on 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit beamforming or receive beamforming. For example, one or more base station antennas or antenna arrays may be located at the same antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having multiple rows and columns of antenna ports, which the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays, which may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals sent via the antenna ports.

[0071] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (such as a base station 105 or a UE 115) to shape or control an antenna beam (such as a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating in a particular orientation with respect to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a particular orientation (such as an antenna array with respect to the transmitting device or the receiving device, or with respect to some other orientation).

[0072] The base station 105 or the UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (such as antenna panels) to perform beamforming operations for directional communications with the UE 115. Some signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the base station 105 in different directions. For example, the base station 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used to identify (such as by a transmitting device such as the base station 105 or a receiving device such as the UE 115) a beam direction for subsequent transmission or reception by the base station 105.

[0073] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate on a logical channel. The medium access control (MAC) layer may perform priority processing, as well as multiplexing of logical channels to transport channels. The MAC layer may also support retransmission at the MAC layer using error detection techniques, error correction techniques, or both, to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide for the establishment, configuration, and maintenance of an RRC connection between a UE 115 and a base station 105 or a core network 130 that supports a radio bearer for user plane data. At the physical layer, a transport channel may be mapped to a physical channel.

[0074] UE 115 and base station 105 can support retransmission of data to increase the possibility of successfully receiving data. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the possibility of successfully receiving data on communication link 125. HARQ operation can include a combination of error detection (such as using cyclic redundancy check (CRC)), forward error correction (FEC) and retransmission (such as automatic repeat request (ARQ)). HARQ operation can improve the throughput at the MAC layer under poor radio conditions (such as low signal-to-noise ratio conditions). In some examples, the device can support the same time slot HARQ feedback, in which the device can provide HARQ feedback for data received in the previous symbol in the time slot in a specific time slot. In other cases, the device can provide HARQ feedback in a subsequent time slot or according to another time interval. HARQ feedback can include a confirmation (ACK) for indicating that the transmission from the base station is successfully received, or a negative confirmation (NACK) for indicating that the transmission is not successfully received.

[0075] In some examples, UE 115 may be configured to send uplink control information (such as CSI and HARQ ACK / NACK feedback) using resources associated with a physical uplink control channel (PUCCH). UE 115 may be configured to send data using resources associated with a physical uplink shared channel (PUSCH).

[0076] In some examples, UE 115 may be configured to multiplex HARQ feedback, such as ACK, with CSI so that ACK and CSI may be sent in the same time slot using the same resources. In some examples, if the time slot is within an inactive DRX duration (e.g., at least a portion of the time slot is within an inactive DRX duration of UE 115), UE 115 may be configured to abandon the transmission of the configuration of CSI in the time slot (i.e., avoid sending CSI). In some examples, UE 115 may be configured to send ACK (if any) in the time slot, regardless of whether CSI is abandoned. In some examples, UE 115 may determine whether the PUCCH resources configured for transmission of CSI and HARQ feedback overlap with the PUSCH resources allocated for transmission of data. If the resources overlap, UE 115 may multiplex CSI and HARQ feedback on PUSCH resources, and use PUSCH resources instead of PUCCH resources to send the multiplexed CSI and HARQ feedback. As discussed in more detail below, the UE 115 may implement one or more techniques for determining whether to send or drop transmission of CSI based on DRX operation, and for determining resources on which to send CSI (if not dropping CSI) and ACK.

[0077] Figure 2 An example of a DRX timing 200 that supports discarding channel state information during discontinuous reception is shown according to one or more aspects of the present disclosure. In some examples, the DRX timing 200 can be implemented by aspects of the wireless communication system 100.

[0078] In some examples, a UE (e.g., UE 115) may receive from a base station (e.g., base station 105) an indication of a first PUCCH resource 220 for sending an ACK to the base station during a time slot 215 and a second PUCCH resource 225 for sending CSI to the base station during a time slot 215. In some examples, the indication of the first PUCCH resource 220 may be provided to the UE via downlink control information (DCI), and the indication of the second PUCCH resource 225 may be provided to the UE via RRC signaling. In some examples, the first PUCCH resource 220 may overlap with the second PUCCH resource 225 in time, frequency, or both.

[0079] In some examples, the UE may determine whether the first PUCCH resource 220 or the second PUCCH resource 225 overlaps with the PUSCH resource 230. For example, the PUSCH resource 230 may have been allocated to the UE for transmission of data to the base station during the time slot 215.

[0080] In some examples, if the first PUCCH resource 220 or the second PUCCH resource 225 (or both) overlaps with the PUSCH resource 230, the UE may select a new PUCCH resource 235 for sending CSI and ACK in the time slot 215. The UE may then multiplex the CSI and ACK on the new PUCCH resource 235 for transmission (e.g., to the base station).

[0081] As described herein, a UE, such as UE 115, may operate in a DRX mode including an active DRX duration 205 and an inactive DRX duration 210. In the DRX timing 200, a time slot 215 including a configured transmission of CSI and ACK is completely within the inactive DRX duration 210. Figure 3A and Figure 3B Described in more detail, in some examples, the UE may forgo transmission of the configuration of CSI in time slot 215 based on determining that time slot 215 is within the inactive DRX duration 210 .

[0082] In some other examples, if the time slot 215 is within the active DRX duration 205 , the UE may determine not to abandon transmission of the CSI and may send the multiplexed CSI and ACK during the time slot 215 .

[0083] Figure 3A and Figure 3B Depicted is a process flow that may be performed by a UE, such as UE 115, based on a DRX timing 200. As depicted in the DRX timing 200, PUCCH resources 220 and 225 configured for transmission of CSI and ACK in time slot 215 overlap with PUSCH resources 230 allocated for transmission of data in time slot 215. In this case, the UE may multiplex the CSI and ACK on the PUSCH resources 230, and use the PUSCH resources 230 (rather than using PUCCH resources) to send the multiplexed CSI and ACK in the time slot. In some examples, this process may be referred to as "piggybacking" the CSI and ACK on the PUSCH resources.

[0084] Alternatively, the UE may select a new PUCCH resource 235 , and multiplex the CSI and ACK on the new PUCCH resource 235 , and transmit the multiplexed CSI and ACK in a time slot using the new PUCCH resource 235 .

[0085] However, as previously discussed, if the UE is operating in DRX mode, the UE may determine whether to forgo transmission of CSI based on whether the CSI is configured to be transmitted in resources in a timeslot that is within the inactive DRX duration. The UE may determine whether to forgo transmission of CSI based on whether the PUCCH resource 225 of the original RRC configuration is configured to be transmitted during the inactive DRX duration (as described in reference to FIG. Figure 3A ), or based on whether new resources selected by the UE (such as new PUCCH resources 235 or PUSCH resources 230) are configured to be transmitted during the inactive DRX duration (as described in reference Figure 3B described), to make this determination.

[0086] Figure 3A An example of a UE process flow if operating in DRX mode is depicted, where the UE determines whether to drop CSI based on the original RRC configured PUCCH resources 225 based on the DRX timing 200 .

[0087] At block 305, the UE may determine whether to abandon the configured transmission of CSI in the time slot. The UE may determine whether to abandon the configured transmission of CSI in the time slot based on whether at least a portion of the time slot including the RRC configured PUCCH resources 225 is within the inactive DRX duration (such as some or all of the symbols of the RRC configured PUCCH resources 225 are configured to be transmitted during the inactive DRX duration). For example, if the UE determines that the starting symbol (e.g., the starting OFDM symbol) of the RRC configured PUCCH resources 220 allocated for CSI is within the inactive DRX duration (e.g., scheduled to be transmitted during the inactive DRX duration), or if the ending symbol of the PUCCH resources 220 allocated for CSI is within the inactive DRX duration, or if any symbol of the PUCCH resources 220 is within the inactive DRX duration, the UE may abandon the configured CSI transmission. In some examples, if the UE determines that the number of symbols of the PUCCH resources allocated for CSI within the inactive DRX duration meets a threshold (such as a majority of symbols), the UE may abandon the configured CSI transmission.

[0088] In the DRX timing 200, the entire time slot 215 is within the inactive DRX duration. Therefore, the UE may determine to drop the configured CSI, and may multiplex the ACK on the PUSCH resources at block 310, and send the multiplexed ACK to the base station using the PUSCH resources.

[0089] Alternatively, if the UE determines that the time slot is not within the inactive DRX duration (i.e., if the UE determines that some or all of the time slots are within the active DRX duration, such that some or all of the PUCCH resources used to send CSI are configured to be sent during the active DRX duration, a scenario not shown in DRX timing 200), at box 315, the UE may multiplex CSI and ACK on the PUSCH resources, and may send the multiplexed CSI and ACK to the base station using the PUSCH resources.

[0090] Figure 3B An alternative process flow is depicted in which the UE determines, based on the DRX timing 200 , whether to forgo transmission of CSI based on new PUCCH resources 235 or PUSCH resources 230 instead of the PUCCH resources 220 and 225 based on the original RRC configuration.

[0091] At block 320, the UE may select new PUCCH resources for sending CSI and ACK. In some examples, the UE may select new PUCCH resources 235 based on determining that one or both of the RRC configured PUCCH resources 225 or the DCI signaled PUCCH resources 220 allocated by the base station overlap with the PUSCH resources 230.

[0092] At block 325, the UE may determine whether the new PUCCH resources 235 overlap (e.g., continue to overlap) with the PUSCH resources 230. If so, at block 340, the UE may determine to report the CSI (i.e., not to abandon transmission of the CSI), and at block 345, the UE may multiplex the ACK and CSI on the PUSCH resources 230 and send (piggyback) the multiplexed ACK and CSI using the PUSCH resources 230.

[0093] Alternatively, if the UE determines at block 325 that the new PUCCH resource 235 does not overlap with the PUSCH resource 230, the UE may determine at block 330 to abandon transmission of the CSI, and at block 335, the UE may multiplex the ACK on the PUSCH resource 230 and send (piggyback) the multiplexed ACK to the base station using the PUSCH resource 230. The UE may abandon transmission of the CSI by excluding multiplexing of the CSI on the PUSCH resource 230.

[0094] In some examples, the UE may multiplex CSI on PUSCH resources 230 (e.g., when RRC-configured PUCCH resources 225 or new PUCCH resources 235 overlap with PUSCH resources 230). In some examples, the UE may multiplex CSI on PUSCH resources 230 with or without additional information (e.g., ACK, other UCI information, or data). The UE may then determine whether to potentially abandon the configured transmission of CSI in a timeslot based on whether at least a portion of the timeslot including the PUSCH resources 230 (e.g., a portion of the timeslot including the PUSCH resources 230 that overlap with the RRC-configured resources 225 or new PUCCH resources 235 that may be configured for transmission of CSI) is within an inactive DRX duration.

[0095] If the UE determines not to abandon the transmission of the configuration of CSI, the UE may use the PUSCH resources 230 to send the multiplexed CSI (if any, with the additional information). If the UE determines to potentially abandon the transmission of the configuration of CSI, the UE may determine whether there is additional information multiplexed on the PUSCH resources 230 (e.g., whether the additional information is multiplexed with the multiplexed CSI or separate from the multiplexed CSI), such as ACK, additional UCI, or data to be sent. If there is additional information multiplexed on the PUSCH resources 230, the UE may use the PUSCH resources 230 to send the multiplexed CSI and the additional information to the base station. That is, if there is additional information multiplexed with the CSI, the UE may not abandon the CSI transmission to avoid abandoning the transmission of the ACK. Otherwise, the UE may abandon the transmission of the configuration of CSI.

[0096] Figure 4 According to one or more aspects of the present disclosure, an example of a DRX sequence 400 that supports discarding channel state information during discontinuous reception is shown. In some examples, the DRX sequence 400 can be implemented by aspects of the wireless communication system 100. In some aspects, the DRX sequence 400 can be similar to the DRX sequence 200, but in the DRX sequence 400, the first portion 215-a of the time slot 215 is within the active DRX duration 405, and the second portion 215-b of the time slot 215 is within the inactive DRX duration 410. As shown in reference Figure 5A and Figure 5B Described in more detail, in some examples, the UE may abandon the configured transmission of CSI in time slot 215 based on determining that a portion (such as second portion 215b) of time slot 215 including resources for sending CSI (e.g., PUCCH resources of the original RRC configuration or new resources) is within the inactive DRX duration 410.

[0097] Figure 5A and Figure 5B An example of a process flow that supports discarding channel state information during discontinuous reception is shown in accordance with one or more aspects of the present disclosure. Figure 5A and Figure 5B A process flow that may be performed by a UE, such as UE 115 , based on DRX timing 400 is depicted.

[0098] As depicted in the DRX timing 400, the PUCCH resources 220 and 225 configured for transmission of CSI and ACK in the time slot 215 overlap with the PUSCH resources 230 allocated for transmission of data in the time slot 215. In this case, the UE may multiplex the CSI and ACK on the PUSCH resources 230, and use the PUSCH resources 230 (instead of using the PUCCH resources) to send the multiplexed CSI and ACK in the time slot. Alternatively, the UE may select a new PUCCH resource 235, and multiplex the CSI and ACK on the new PUCCH resource 235, and use the new PUCCH resource 235 to send the multiplexed CSI and ACK in the time slot.

[0099] As previously discussed, however, if the UE is operating in DRX mode, the UE may determine whether to forgo transmission of CSI based on whether the CSI is configured to be transmitted using resources in a timeslot that is within the inactive DRX duration. The UE may determine whether to forgo transmission of CSI based on whether the PUCCH resources 225 of the original RRC configuration are configured to be transmitted during the inactive DRX duration (as described in reference to FIG. Figure 5A ), or based on whether new resources selected by the UE (such as new PUCCH resources 235) are configured to be transmitted during the inactive DRX duration (as described in reference Figure 5B described), to make this determination.

[0100] Figure 5A Depicted under the scenario of DRX timing 400 , an example of a UE process flow if operating in DRX mode, in which the UE determines whether to drop transmission of CSI based on the original RRC configured PUCCH resources 225 . Figure 5A The process flow can be similar to Figure 3A process flow, although the results may differ from Figure 3A The results in are different because the first portion 215 - a of the time slot 215 is within the active DRX duration 405 and the second portion 215 - b of the time slot 215 is within the inactive DRX duration 410 .

[0101] At block 505, the UE may determine whether to abandon transmission of the configuration of CSI in the time slot. The UE may determine whether to abandon transmission of the configuration of CSI in the time slot based on whether at least a portion of the time slot including the RRC configured PUCCH resource 225 is within the inactive DRX duration 410. In this example, the second portion 215-b of the time slot 215 is within the inactive DRX duration, so the UE may determine to abandon transmission of CSI. As described in reference Figure 3A As described, if the UE determines that the starting symbol (e.g., starting OFDM symbol) of the RRC-configured PUCCH resource 225 allocated for CSI is within the inactive DRX duration 410, or if the ending symbol of the PUCCH resource 225 allocated for CSI is within the inactive DRX duration 410, or if any symbol of the PUCCH resource 225 is within the inactive DRX duration, the UE may abandon the configured CSI transmission. In some examples, if the UE determines that the number of symbols of the PUCCH resource 225 allocated for CSI within the inactive DRX duration 410 meets a threshold (e.g., most symbols), the UE may abandon the configured CSI transmission. For example, the UE may determine that a first number of symbols of the PUCCH resource 225 is within the active DRX duration 405, and a second number of symbols of the PUCCH resource 225 is within the inactive DRX duration 410. If the first number of symbols is greater than the second number of symbols, the UE may determine to report (e.g., send) the CSI, or if the second number of symbols is greater than the first number of symbols, it may determine to abandon the transmission of the CSI.

[0102] If the UE determines to discard the configured CSI, the UE may multiplex ACK on the PUSCH resources and send the multiplexed ACK to the base station using the PUSCH resources at block 510. Alternatively, if the UE determines not to discard the configured CSI, the UE may multiplex CSI and ACK on the PUSCH resources at block 515 and send the multiplexed CSI and ACK to the base station using the PUSCH resources.

[0103] Figure 5B Depicted under the scenario of DRX timing 400 is an alternative example of a UE process flow if operating in DRX mode, in which the UE determines whether to drop CSI based on new PUCCH resources 235 instead of based on the original RRC configured PUCCH resources 225.

[0104] At block 520, the UE may select new PUCCH resources 235 for sending CSI and ACK. In some examples, the UE may select new PUCCH resources 235 based on determining that RRC-configured PUCCH resources 225 allocated by the base station overlap with PUSCH resources 230.

[0105] At block 525, the UE may determine whether the new PUCCH resources 235 overlap (e.g., continue to overlap) with the PUSCH resources 230. If so, at block 530, the UE may determine to report the CSI (i.e., not to abandon transmission of the CSI), and at block 535, the UE may multiplex the ACK and CSI on the PUSCH resources 230 and send the multiplexed ACK and CSI using the PUSCH resources 230.

[0106] Alternatively, if the UE determines at block 525 that the new PUCCH resource 235 does not overlap with the PUSCH resource 230, the UE may determine at block 540 whether some or all of the new PUCCH resource 235 is in a portion within the inactive DRX duration 410 in the time slot 215. For example, the UE may determine whether a starting symbol, an ending symbol, or another symbol of the new PUCCH resource 235 is in a portion within the inactive DRX duration 410 in the time slot 215, or whether the number of symbols of the new PUCCH resource 235 in the inactive DRX duration 410 satisfies a threshold (e.g., a majority of symbols).

[0107] The UE may determine whether to abandon transmission of CSI, for example, based on whether some or all of the new PUCCH resources 235 are in a portion of the inactive DRX duration 410 in the time slot 215, or conversely based on whether some or all of the new PUCCH resources 235 are in a portion of the active DRX duration in the time slot.

[0108] If the UE determines at block 540 that some or all of the new PUCCH resources 235 (e.g., if the first symbol, the last symbol, another symbol, or all symbols) are within a portion of the active DRX duration 405 in the time slot 215, the UE may determine to report CSI at block 545, and may multiplex ACK and CSI on the new PUCCH resources 235 at block 550. In some examples, the UE may send the multiplexed ACK and CSI using the new PUCCH resources. In some examples, the UE may send the multiplexed ACK and CSI using the new PUCCH resources by time division multiplexing uplink transmissions of the multiplexed ACK and CSI with PUSCH transmissions on the new PUCCH resources.

[0109] If the UE determines at 540 that some or all of the new PUCCH resources 235 (e.g., based on the same symbol evaluated at block 540, such as the first symbol, the last symbol, another symbol, or all symbols) are in a portion of the inactive DRX duration 410 in the time slot 215, the UE may determine to forgo transmission of the CSI at 555, and may multiplex the ACK on the PUSCH resources 230 at 560. In some examples, the UE may use the PUSCH resources to send the multiplexed ACK.

[0110] Figure 6 An example of a DRX sequence 600 that supports discarding channel state information during discontinuous reception is shown according to one or more aspects of the present disclosure. In some examples, the DRX sequence 600 can be implemented by aspects of the wireless communication system 100. The DRX sequence 600 can be similar to the DRX sequences 200 and 400, but in this example, the first portion 215-c of the time slot 215 is within an active DRX duration 605, and the second portion 215-d of the time slot 215 is within an inactive DRX duration 610. In this example, in the middle of a configured CSI transmission on a new PUCCH resource 235, the UE transitions from the active DRX duration 605 to the inactive DRX duration 610. As described in reference to Fig. 7A and Figure 7B Described in more detail, in some examples, the UE may abandon the configured transmission of CSI in time slot 215 based on determining that a portion of time slot 215 (e.g., second portion 215-d) that includes some or all of the new PUCCH resources for sending CSI is within an inactive DRX duration 610.

[0111] Fig. 7A and Figure 7B An example of a process flow that supports discarding channel state information during discontinuous reception is shown in accordance with one or more aspects of the present disclosure. Fig. 7A and Figure 7B A process flow that may be performed by a UE, such as UE 115 , in the context of DRX timing 600 is depicted.

[0112] Fig. 7A Describe and Figure 5A A process flow similar to the process flow depicted in Fig. 7AIn the process flow covered, the UE can determine whether to abandon the configured transmission of CSI in the time slot based on the RRC configured PUCCH resources at box 705, and depending on the result of box 705, the UE can abandon the transmission of CSI and multiplex ACK on PUSCH resources at box 710, or report CSI and multiplex ACK and CSI on PUSCH resources at box 715.

[0113] Figure 7B An alternative example of a UE procedure if operating in DRX mode is depicted, in which the UE determines whether to drop CSI based on new PUCCH resources 235 rather than based on the original RRC configured PUCCH resources 225. Figure 7B Describe similar to Figure 5B , with the difference occurring at block 740. At block 740, the UE may determine whether some or all of the new PUCCH resources 235 are in a portion of the inactive DRX duration 610 in the time slot 215 by determining whether each symbol of the new PUCCH resources 235 is in the inactive DRX duration 610. In some examples, if any symbol of the new PUCCH resources 235 is in a portion of the inactive DRX duration 610 in the time slot 215, the UE may determine to forgo transmission of the CSI report at block 755, and may multiplex an ACK on the PUSCH resource at block 760. The UE may then send the multiplexed ACK to the base station using the PUSCH resource.

[0114] Conversely, in some examples, if the UE determines that none of the symbols of the new PUCCH resource 235 are in a portion of the inactive DRX duration 610 in the time slot 215, the UE may determine to report CSI at block 745, and may proceed with multiplexing ACK and CSI on the new PUCCH resource 235, and sending the multiplexed ACK and CSI to the base station using the new PUCCH resource 235. In some examples, the UE may send the multiplexed ACK and CSI using the new PUCCH resource 235 by time division multiplexing the transmission of the ACK and CSI on the new PUCCH resource 235 with the uplink transmission on the PUSCH resource.

[0115] Figure 8 An example of a DRX timing 800 that supports discarding channel state information during discontinuous reception is shown according to one or more aspects of the present disclosure. In some examples, the DRX timing 800 may be implemented by aspects of the wireless communication system 100. The DRX timing 800 may be an example of a DRX timing if one or more multi-CSI PUCCH resources are configured.

[0116] For example, the UE may be configured with a first PUCCH resource 815 for sending a first periodic CSI (P-CSI) report, a second PUCCH resource 820 for sending a second P-CSI report, a third PUCCH resource 830 for sending a semi-persistent CSI (SP-CSI) report, a fourth PUCCH resource 835 for sending ACK, and a PUSCH resource 840 for sending data. The UE may also be configured with a first multi-CSI PUCCH resource 825 and a second multi-CSI PUCCH resource 845. In some examples, the multi-CSI PUCCH resources 825 and 845 may be used to send multiple CSI reports.

[0117] In some examples, if any of the PUCCH resources 815, 820, or 830 used to transmit periodic CSI reports or semi-persistent CSI reports overlap with each other, the UE may multiplex multiple CSI reports on one of the two multi-CSI PUCCH resources 825 or 845, and may use the multi-CSI PUCCH resources 825 or 845 to transmit the multiplexed CSI reports. In some examples, the selection of the multi-CSI PUCCH resources 825 and 845 for transmission of the multiple CSI reports may be based on the total payload size of the multiplexed CSI reports and other factors. Therefore, the activation of the semi-persistent CSI report may change the selection of the multi-CSI PUCCH resources 825 and 845. In the DRX timing 800, one of the multi-CSI PUCCH resources 825 is in a portion within the active DRX duration 805 in the time slot 215, and the other multi-CSI PUCCH resource 845 is in a portion within the inactive DRX duration 810 in the time slot 215. In some examples, the UE behavior process may depend on whether and how the UE determines that the CSI is in a portion of the inactive DRX duration 810 in the time slot 215, such as whether the UE makes this determination before or after multiplexing multiple CSI reports on the multiple CSI PUCCH resources 825 or 845, as described in reference to Fig. 9A and Fig. 9B as described.

[0118] Fig. 9A and Fig. 9B An example of a process flow that supports discarding channel state information during discontinuous reception is shown in accordance with one or more aspects of the present disclosure. Fig. 9A and Fig. 9B A process flow that may be performed by a UE, such as UE 115 , in the context of DRX timing 800 is depicted.

[0119] Fig. 9AA process flow is depicted in which the UE may determine at block 905 whether to abandon the transmission of the configuration of CSI in the time slot based on the RRC configured PUCCH resources, such as the first PUCCH resource 815, the second PUCCH resource 820, or the third PUCCH resource 830. That is, the UE may determine whether to abandon each CSI (such as each periodic CSI and each semi-persistent CSI) based on the corresponding RRC configured PUCCH resources for the CSI. If the UE determines not to abandon one or more of the CSI, the UE may select one or more new multi-CSI PUCCH resources 825 and 845 for sending multiple CSI reports at block 910. At block 915, the UE may multiplex the CSI with other uplink control information (such as ACK), with PUSCH data, or with both. In some examples, the UE may use the new multi-CSI PUCCH resources 825 and 845 to send the multiplexed CSI and (if necessary) ACK and PUSCH data. In some examples, the UE may use PUSCH resources to send multiplexed CSI and (if needed) ACK along with PUSCH data.

[0120] Fig. 9B An alternative process flow is depicted in which the UE determines whether to drop each CSI based on new multi-CSI PUCCH resources 825 and 845 rather than based on the original RRC configured PUCCH resources 815, 820, and 830. That is, the UE may determine whether to drop each CSI after selecting a multi-CSI PUCCH resource for transmitting the CSI.

[0121] At block 920, the UE may select new multi-CSI PUCCH resources 825 or 845 for transmitting multiple CSIs. At block 925, the UE may determine that one or more of the CSIs overlap with other control information, and may select new PUCCH resources based on the determination. In some examples, the new PUCCH resources may be the same as the multi-CSI PUCCH resources. In some examples, the new PUCCH resources may be different from the multi-CSI PUCCH resources.

[0122] At block 930 , the UE may determine whether the new PUCCH resources overlap with the PUSCH resources 840 .

[0123] The UE may then proceed to perform additional processes shown in blocks 935, 945, 950, 955, 960, 965, and 970, which are similar to those described in reference to Figure 7B Corresponding blocks 730, 735, 740, 745, 750, 755 and 760 are described.

[0124] Fig.10 An example of resource allocation 1000 that supports discarding channel state information during discontinuous reception is shown in accordance with one or more aspects of the present disclosure.

[0125] In some examples, the UE may be configured to send multiple repetitions of the same CSI using PUCCH resources 1005-a, 1005-b, 1005-c, and 1005-d in multiple time slots 1010-a, 1010-b, 1010-c, and 1010-d, respectively. In this example, the UE may determine whether to discard each CSI repetition (e.g., individually) based on the RRC-configured PUCCH resources 1005-a, 1005-b, 1005-c, and 1005-c for each CSI repetition. For example, the UE may perform the above steps for each CSI repetition as described in reference to Figure 2 - The operation described in the process flow related to Figure 9 is to determine whether to abandon each CSI repetition. In this case, the UE can determine to abandon all CSI repetitions to send all CSI repetitions, or abandon some CSI repetitions in the CSI repetitions and send other CSI repetitions.

[0126] In some examples, the UE may determine whether to abandon all CSI repetitions based on the PUCCH resource 1005-a configured by the RRC for the first CSI repetition. For example, the UE may perform a PUCCH resource 1005-a for the first CSI repetition, such as referring to Figure 2 - Process flows of those described in Figure 9. In this example, the UE may determine to drop all CSI repetitions or to send all CSI repetitions, but may not determine to drop some of the CSI repetitions and to send others.

[0127] Fig.11 An example of a DRX timing 1100 that supports discarding channel state information during discontinuous reception is shown in accordance with one or more aspects of the present disclosure.

[0128] In some examples, if a time slot is scheduled for communication, the UE may use timing advance 1120, such as shown in DRX timing 1100. The timing advance may be a duration that advances the time slot in time from a first time (e.g., an initial time) to a second time (e.g., an offset time). That is, the time slot may be configured to start during an earlier time based on the timing advance 1120.

[0129] In some examples, the MAC layer may consider the transmission time of CSI within a time slot without timing advance, such as the transmission time associated with CSI on PUCCH 1115-a. This time may be referred to as a logical transmission time. In some examples, the PHY layer may consider the transmission time of CSI within a time slot that includes a timing advance, such as the transmission time associated with CSI on PUCCH 1115-b. This time may be referred to as a physical transmission time.

[0130] In some examples, the UE may determine whether to discard CSI based on logical transmission time (ie, excluding timing advance 1120) or based on physical transmission time (ie, including timing advance 1120).

[0131] In DRX timing 1100, CSI on PUCCH 1115-a occurs in the inactive DRX duration 1110 (based on the logical transmission time). In contrast, part of the CSI on PUCCH 1115-b occurs in the active DRX duration 1105, and part of the CSI on PUCCH 1115-b occurs in the inactive DRX duration 1110 (based on the physical transmission time). Therefore, if the UE determines whether to abandon the transmission of CSI based on the logical transmission time (as shown in FIG. Figure 2-Figure 10 ), the UE may determine to abandon the transmission of CSI because the CSI on PUCCH 1115-a may occur entirely in the inactive DRX duration. Alternatively, if the UE determines whether to abandon the transmission of CSI based on the physical transmission time (as described in reference Figure 2-Figure 10 As described), the UE may determine whether to abandon transmission of the CSI or to send the CSI, depending on whether the UE makes the decision based on the starting symbol of the CSI, the ending symbol of the CSI, or one or more other symbols of the CSI.

[0132] Fig.12 An example of a DRX timing 1200 that supports discarding channel state information during discontinuous reception is shown in accordance with one or more aspects of the present disclosure.

[0133] In some examples, the PUCCH resource 225 may include a plurality of symbols 1215, such as OFDM symbols. Each symbol may include a plurality of chips. In some examples, a chip may be the smallest time unit in an NR wireless communication system and may be referred to as Tc. In the DRX timing 1200, the UE may switch from an active DRX duration 1205 to an inactive DRX duration 1210 during the start symbol of the PUCCH resource 225. In some examples, the UE may determine whether to abandon the transmission of CSI based on the start chip of one or more symbols, rather than based on one or more symbols. That is, the UE may determine whether to abandon the transmission of CSI at a finer granularity level than at the symbol level. For example, the UE may determine whether to abandon the transmission of CSI based on the start chip of the start symbol rather than based on the entire start symbol. In some examples, the UE may determine whether to abandon the transmission of CSI based on the start chip of one or more other symbols (such as based on the start chip of the end symbol or based on the start chip of one or more other symbols). For example, if the UE determines that the number of starting chips of symbols in the inactive DRX duration meets a threshold (such as most of the starting chips of the PUCCH resources allocated for CSI), the UE may abandon the configured CSI transmission. That is, if the number of starting chips of the PUCCH resources in the inactive DRX duration is greater than (or greater than or equal to) the number of starting chips of the PUCCH resources in the active DRX duration, the UE may decide to abandon the transmission of CSI.

[0134] Fig.13 A block diagram of a device 1305 that supports discarding channel state information during discontinuous reception according to aspects of the present disclosure is shown. The device 1305 can be an example of aspects of the UE 115 as described herein. The device 1305 may include a receiver 1310, a communication manager 1315, and a transmitter 1320. The device 1305 may be implemented at least in part by one or both of a modem and a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0135] The receiver 1310 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to discarding channel state information during discontinuous reception). The information may be communicated to other components of the device 1305. The receiver 1310 may be a reference Fig.16 Examples of various aspects of the described transceiver 1620. The receiver 1310 may utilize a single antenna or a group of antennas.

[0136] The communication manager 1315 may receive an indication of a first resource associated with a PUCCH for transmitting CSI to a base station in a time slot, and determine whether one or more symbols of the first resource associated with the PUCCH in the time slot are included in a portion of the time slot that is within an inactive discontinuous reception duration for the UE. The communication manager 1315 may determine the CSI, and abandon transmission of the configuration of the CSI in the time slot based at least in part on determining that one or more symbols of the first resource associated with the PUCCH in the time slot are included in a portion of the time slot that includes an inactive discontinuous reception duration for the UE.

[0137] The communications manager 1315 may also receive an indication of a third resource of the physical uplink control channel for transmitting channel state information in the time slot.

[0138] The communication manager 1315 may also determine a first resource associated with the PUCCH for sending CSI and an acknowledgement associated with a signal received by the UE to the base station in the time slot, and select a second resource associated with the PUCCH for sending the CSI and the acknowledgement in the time slot based on the determination of the first resource. The communication manager 1315 may determine that the second resource associated with the PUCCH overlaps with a third resource associated with the PUSCH, determine whether one or more symbols of the second resource associated with the PUCCH in the time slot are included in a portion of the time slot that is within the inactive discontinuous reception duration for the UE based on the determination that the second resource associated with the PUCCH overlaps with the third resource associated with the PUSCH. The communication manager 1315 may select a fourth resource for sending the acknowledgement based on the determination that one or more symbols of the second resource associated with the PUCCH in the time slot are included in a portion of the time slot that is within the inactive discontinuous reception duration for the UE, the fourth resource including the second resource or the third resource, multiplex the acknowledgement with data for sending on the PUSCH on the fourth resource, and send the multiplexed acknowledgement and data to the base station using the fourth resource.

[0139] The communication manager 1315 may also multiplex the CSI on the first resource based on determining that the second resource of the PUCCH for sending the CSI overlaps with the first resource of the PUSCH for sending data to the base station in the time slot, and determine whether to multiplex the additional information on the PUSCH based on determining that at least a portion of the time slot includes an inactive discontinuous reception duration for the UE. The communication manager 1315 may select the first resource based at least in part on the indication of the third resource. The communication manager 1315 may determine whether at least a portion of the time slot includes an inactive discontinuous reception duration for the UE. The communication manager 1315 may determine whether at least a portion of the time slot includes an inactive discontinuous reception duration by determining whether the first symbol of the first resource is configured to be sent during the inactive discontinuous reception period. The communication manager 1315 may send the multiplexed CSI and the additional information on the first resource of the PUSCH based on determining that the CSI is multiplexed with the additional information. The communication manager 1315 may be an example of various aspects of the communication manager 1610 described herein.

[0140] The transmitter 1320 may transmit signals generated by other components of the device 1305. In some examples, the transmitter 1320 may be co-located with the receiver 1310 in a transceiver component. For example, the transmitter 1320 may be a reference Fig.16 Examples of various aspects of the described transceiver 1620. The transmitter 1320 may utilize a single antenna or a group of antennas.

[0141] Fig.14 A block diagram of a device 1405 that supports discarding channel state information during discontinuous reception according to aspects of the present disclosure is shown. The device 1405 can be an example of aspects of the device 1305 or UE 115 as described herein. The device 1405 may include a receiver 1410, a communication manager 1415, and a transmitter 1450. The device 1405 may be implemented at least in part by one or both of a modem and a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0142] Receiver 1410 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to discarding channel state information during discontinuous reception). The information may be communicated to other components of device 1405. Receiver 1410 may be a reference Fig.16 Examples of various aspects of the described transceiver 1620. The receiver 1410 may utilize a single antenna or a group of antennas.

[0143] The communication manager 1415 may be an example of aspects of the communication manager 1315 as described herein. The communication manager 1415 may include a PUCCH resource component 1420, a DRX component 1425, a PUSCH resource component 1430, a multiplexing component 1435, a transmission component 1440, an overlay component 1445, and a CSI component 1450.

[0144] The PUCCH resource component 1420 may receive an indication of a first resource associated with the PUCCH for sending CSI to the base station in the time slot. The PUCCH resource component 1420 may determine the first resource associated with the PUCCH for sending CSI and an acknowledgment associated with a signal received by the UE to the base station in the time slot, and select a second resource associated with the PUCCH for sending the CSI and the acknowledgment in the time slot based on determining the first resource.

[0145] The PUCCH resource component 1420 may receive an indication of a third resource associated with the PUCCH for transmitting CSI to the base station in the slot.

[0146] The DRX component 1425 may determine whether one or more symbols of a first resource associated with a PUCCH in a time slot are included in a portion of an inactive discontinuous reception duration for the UE in the time slot. The DRX component 1425 may determine whether one or more symbols of a second resource associated with a PUCCH in a time slot are included in a portion of an inactive discontinuous reception duration for the UE in the time slot based on determining that a second resource associated with the PUCCH overlaps with a third resource associated with the PUSCH. The DRX component 1425 may determine whether at least a portion of the time slot includes an inactive discontinuous reception duration for the UE. The DRX component 1425 may determine whether at least a portion of the time slot includes an inactive discontinuous reception duration for the UE by determining whether a first symbol of the first resource is configured to be sent during an inactive discontinuous reception period, and whether at least a portion of the time slot includes an inactive discontinuous reception duration.

[0147] The PUSCH resource component 1430 may determine a second resource for the PUSCH.The PUSCH resource component 1430 may select a first resource for a physical uplink shared channel based on the indication of the third resource.

[0148] The multiplexing component 1435 may multiplex the acknowledgment on a second resource of the PUSCH before sending the acknowledgment to the base station. The multiplexing component 1435 may select a fourth resource for sending the acknowledgment based on determining whether one or more symbols of the second resource associated with the PUCCH in the time slot are included in a portion of the time slot that is within an inactive discontinuous reception duration for the UE, the fourth resource including the second resource or the third resource, and multiplexing the acknowledgment with data for sending on the PUSCH on the fourth resource. The multiplexing component 1435 may multiplex the CSI on the first resource based on determining that the second resource of the PUCCH used to send the CSI overlaps with the first resource of the PUSCH used to send data to the base station in the time slot, and determine whether to multiplex additional information on the PUSCH based on determining that at least a portion of the time slot includes an inactive discontinuous reception duration for the UE.

[0149] Transmitting component 1440 may transmit an acknowledgment associated with a signal received by the UE to the base station in the time slot. Transmitting component 1440 may transmit the multiplexed acknowledgment and data to the base station using the fourth resource. Transmitting component 1440 may transmit the multiplexed CSI and the additional information on the first resource of the PUSCH based on determining that the CSI is multiplexed with the additional information.

[0150] Overlap component 1445 can determine that second resources associated with the PUCCH overlap with third resources associated with the PUSCH.

[0151] The CSI component 1450 can determine the CSI.

[0152] The transmitter 1455 can transmit signals generated by other components of the device 1405. In some examples, the transmitter 1455 can be co-located with the receiver 1410 in the transceiver component. For example, the transmitter 1455 can be a reference Fig.16 Examples of various aspects of the described transceiver 1620. The transmitter 1455 may utilize a single antenna or a group of antennas.

[0153] Fig.15 A block diagram of a communication manager 1505 that supports discarding channel state information during discontinuous reception in accordance with aspects of the present disclosure is shown. The communication manager 1505 may include a PUCCH resource component 1510, a DRX component 1515, a PUSCH resource component 1520, a multiplexing component 1525, a transmission component 1530, a CSI component 1535, and an overlay component 1540.
