Given the rapid development in communications, there will also be future type communication technologies and systems in which the present disclosure may be embodied. It should not be seen as limiting the scope of the present disclosure to only the aforementioned systems.
[0109] As used herein, the term “network device” generally refers to a node in a communication network via which a terminal device can access the communication network and receive services therefrom. The network device may refer to a base station (BS) or an access point (AP) , for example, a node B (NodeB or NB) , a radio access network (RAN) node, an evolved NodeB (eNodeB or eNB) , an NR NB (also referred to as a gNB) , a remote radio unit (RRU) , a radio header (RH) , an infrastructure device for a V2X (vehicle-to-everything) communication, a transmission and reception point (TRP) , a reception point (RP) , a remote radio head (RRH) , a relay, an integrated access and backhaul (IAB) node, a low power node such as a femto BS, a pico BS, and so forth, depending on the applied terminology and technology.
[0110] As used herein, the term “terminal device” generally refers to any end device that may be capable of wireless communications. By way of example rather than a limitation, a terminal device may also be referred to as a communication device, a user equipment (UE) , an end user device, a subscriber station (SS) , an unmanned aerial vehicle (UAV) , a portable subscriber station, a mobile station (MS) , or an access terminal (AT) . The terminal device may include, but is not limited to, a mobile phone, a cellular phone, a smart phone, a voice over IP (VoIP) phone, a wireless local loop phone, a tablet, a wearable terminal device, a personal digital assistant (PDA) , a portable computer, a desktop computer, an image capture terminal device such as a digital camera, a gaming terminal device, a music storage and playback appliance, a vehicle-mounted wireless terminal device, a wireless endpoint, a mobile station, laptop-embedded equipment (LEE) , laptop-mounted equipment (LME) , a USB dongle, a smart device, wireless customer-premises equipment (CPE) , an internet of things (loT) device, a watch or other wearable, a head-mounted display (HMD) , a vehicle, a drone, a medical device (for example, a remote surgery device) , an industrial device (for example, a robot and / or other wireless devices operating in an industrial and / or an automated processing chain contexts) , a consumer electronics device, a device operating on commercial and / or industrial wireless networks, and the like. In the following description, the terms: “terminal device, ” “communication device, ” “terminal, ” “user equipment” and “UE, ” may be used interchangeably.
[0111] As mentioned above, a UE may be configured with measurement gaps (MGs) to measure downlink signals. For example, the UE may be configured with a SSB measurement timing configuration (SMTC) window, and may perform measurements in the SMTC window to assist cell selection and cell re-selection. An example of the configuration parameter for the SMTC window may be:
[0112] For example, if the periodicityAndOffset configures that the periodicity is 5 and the offset is 4, and duration =sf1, then it means the measurement period is 5 subframes and a UE should perform the measurement in the fourth subframe.
[0113] Other measurement gaps (MGs) may be used by 5G system for handoff and beam selection procedures. The measurement configuration for such MGs may be similar to the configuration of SMTC window. The measurement is key for best beam and cell selection during mobility. Thus, it has been specified in the 3GPP specification that there should be no data transmission during the measurement gaps or SMTC windows.
[0114] Extended reality (XR) is a broad term covering augmented reality (AR) , mixed reality (MR) and virtual reality (VR) . Along with cloud computing, XR applications typically require high throughput and low latency, and have a big packet size and variable data packet size. For an XR service, reliability and latency are important requirements. If data transmission in the measurement gap and SMTC window is not supported, then frequent measurement gaps would add latency to the XR traffic. For example, if there is XR traffic that should be transmitted, but it is in the measurement gap or SMTC window, it would be delayed. Therefore, it is necessary to study how to guarantee the latency of XR traffic. For example, there are some discussions in Release 19 to support transmission and reception in measurement gap for RRM.
[0115] For solutions based on triggering / enabling by network signaling to enable transmission / reception (Tx / Rx) in gaps / restrictions that are caused by RRM measurements consider at least one of the following alternatives or combinations for further down-selection:
[0116] For solutions based on triggering / enabling by network signaling to enable Tx / Rx in gaps / restrictions that are caused by RRM measurements consider the following alternatives or combinations for further down-selection:

It should be noted that minimum time offset (s) between the end of (the first) received dynamic indication and the start of corresponding gap (s) / restriction (s) occasion that is going to be skipped shall be introduced.

[0124] Alt. 3-4: Gaps / restrictions that are caused by RRM measurements are skipped based on semi-statically configured priority information for particular semi-statically pre-configured Tx / Rx and / or particular gaps / restrictions.
[0125] In the present disclosure, the term “measurement gap” is used for the following embodiments. It should be understood that the measurement gap may refer to any measurement gap / window for measurements. The term “measurement gap” may be interchangeably with one of the following: an SMTC window, a restriction gap, a gap / restriction caused by RRM measurements, or the like, and the present disclosure does not limit for this aspect.
[0126] In view of the above, embodiments of the present disclosure provide a solution of a skipping indication for measurement gaps. In the solution, a UE receives, from a base station, a measurement gap-related indication indicative of whether to skip a measurement gap. The measurement gap-related indication may be carried in a DCI and the UE may determine whether to skip the measurement gap based on a time domain location of the measurement gap-related indication and a time offset threshold. Alternatively or additionally, the measurement gap-related indication may be carried in a RRC parameter and the UE may determine whether to skip the measurement gap based on the measurement gap-related indication indicative of whether to perform a measurement gap skipping for a corresponding time duration. In this way, a scheme for determining whether a measurement gap should be skipped may be designed.
[0127] Aspects of the present disclosure are described in the context of a wireless communications system.
[0128] FIG. 1 illustrates an example of a wireless communications system 100 that supports a skipping indication for measurement gaps in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more network entities 102 (also referred to as network equipment (NE) ) , one or more UEs 104, a core network 106, and a packet data network 108. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as an NR network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) , IEEE 802.16 (WiMAX) , IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.
[0129] The one or more network entities 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a radio access network (RAN) , a base transceiver station, an access point, a NodeB, an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. A network entity 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, a network entity 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface.
[0130] A network entity 102 may provide a geographic coverage area 112 for which the network entity 102 may support services (e.g., voice, video, packet data, messaging, broadcast, etc. ) for one or more UEs 104 within the geographic coverage area 112. For example, a network entity 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, a network entity 102 may be moveable, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but the different geographic coverage areas 112 may be associated with different network entities 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0131] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, or a subscriber device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (IoT) device, an Internet-of-Everything (IoE) device, or machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In some other implementations, a UE 104 may be mobile in the wireless communications system 100.
[0132] The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in FIG. 1. A UE 104 may be capable of communicating with various types of devices, such as the network entities 102, other UEs 104, or network equipment (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network equipment) , as shown in FIG. 1. Additionally, or alternatively, a UE 104 may support communication with other network entities 102 or UEs 104, which may act as relays in the wireless communications system 100.
[0133] A UE 104 may also be able to support wireless communication directly with other UEs 104 over a communication link 114. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.
[0134] A network entity 102 may support communications with the core network 106, or with another network entity 102, or both. For example, a network entity 102 may interface with the core network 106 through one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the network entities 102 may communicate with each other directly (e.g., between the network entities 102) . In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106) . In some implementations, one or more network entities 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) .
[0135] In some implementations, a network entity 102 may be configured in a disaggregated architecture, which may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 102, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 102 may include one or more of a central unit (CU) , a distributed unit (DU) , a radio unit (RU) , a RAN Intelligent Controller (RIC) (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, or any combination thereof.
[0136] An RU may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 102 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 102 may be located in distributed locations (e.g., separate physical locations) . In some implementations, one or more network entities 102 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0137] Split of functionality between a CU, a DU, and an RU may be flexible and may support different functionalities depending upon which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CU and a DU such that the CU may support one or more layers of the protocol stack and the DU may support one or more different layers of the protocol stack. In some implementations, the CU may host upper protocol layer (e.g., a layer 3 (L3) , a layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU may be connected to one or more DUs or RUs, and the one or more DUs or RUs may host lower protocol layers, such as a layer 1 (L1) (e.g., physical (PHY) layer) or an L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU.
[0138] Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU and an RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or multiple different cells (e.g., via one or more RUs) . In some implementations, a functional split between a CU and a DU, or between a DU and an RU may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU) .
[0139] A CU may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU may be connected to one or more DUs via a midhaul communication link (e.g., F1, F1-c, F1-u) , and a DU may be connected to one or more RUs via a fronthaul communication link (e.g., open fronthaul (FH) interface) . In some implementations, a midhaul communication link or a fronthaul communication link may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 102 that are in communication via such communication links.
[0140] The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management functions (AMF) ) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.
[0141] The core network 106 may communicate with the packet data network 108 over one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the core network 106 via a network entity 102. The core network 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106) .
[0142] In the wireless communications system 100, the network entities 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the network entities 102 and the UEs 104 may support different resource structures. For example, the network entities 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the network entities 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the network entities 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The network entities 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0143] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0144] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0145] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0146] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the network entities 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the network entities 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the network entities 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0147] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.
[0148] Reference is now made to FIG. 2, which illustrates an example signaling chart of a communication process that supports a skipping indication for measurement gaps in accordance with some example embodiments of the present disclosure. For the purpose of discussion, the process 200 will be described with reference to FIG. 1. The process 200 may involve the UE 104 and the network entity 102. It is to be understood that the steps and the order of the steps in FIG. 2 are merely for illustration, and not for limitation. It is to be understood that process 200 may further include additional blocks not shown and / or omit some shown blocks, and the scope of the present disclosure is not limited in this regard.
[0149] As shown in FIG. 2, the network entity 102 transmits (202) a measurement gap-related indication 204 indicative of whether to skip a measurement gap to the UE 104. The UE 104 receives (206) the measurement gap-related indication 204 from the network entity 102. The UE 104 determines (208) whether to skip the measurement gap. In some embodiments, the measurement gap-related indication 204 is carried in a DCI and the UE 104 determines whether to skip the measurement gap based on a time domain location of the measurement gap-related indication 204 and a time offset threshold. In some embodiments, the measurement gap-related indication 204 is carried in a RRC parameter and the UE 104 determines whether to skip the measurement gap based on the measurement gap-related indication 204 indicative of whether to perform a measurement gap skipping for a corresponding time duration. Similarly, the network entity 102 determines (210) whether to skip the measurement gap. The UE 104 and the network entity 102 have a common understanding on whether the to skip the measurement gap. If it is determined to skip the measurement gap, the UE 104 will not perform measurements and may perform transmission or reception in the measurement gap. If it is determined that the measurement gap is not skipped, the UE 104 will perform measurements in the measurement gap and will not perform transmission or reception in the measurement gap.
[0150] Hereinafter, some implementations of the skipping indication for measurement gaps will be further detailed in regard to various specific aspects.
[0151] The first specific aspect is how to determine to skip a measurement gap based on the time offset threshold. If the UE 104 receives a DCI indicating not to skip a measurement gap, the UE 104 may determine to skip the measurement gap based on the DCI while the time offset threshold is not used for the determination. If the UE 104 receives a DCI indicating to skip a measurement gap, the UE 104 may determine whether to skip the measurement gap based on the DCI and the time offset threshold. As used herein, the terms “time offset threshold” and “timeline” may be used interchangeably. Other terms may also be used to refer to the same element or feature.
[0152] In some embodiments, the measurement gap-related indication 204 may be carried in the DCI, and the measurement gap-related indication 204 may be indicative of whether to skip at least one measurement gap located after the DCI. The at least one measurement gap may include the measurement gap. In other words, the UE 104 may receive a DCI carrying the measurement gap-related indication 204 from the network entity 102 to indicate whether one or more measurement gaps after the DCI should be skipped or not.
[0153] In some embodiments, the measurement gap-related indication 204 may include a first number of bits, and each bit among the first number of bits is indicative of whether to skip a corresponding measurement gap among a first number of measurement gaps. The first number may be an integer equal to or larger than one. In some embodiments, the first number may be predefined. Alternatively, the UE 104 may receive an indication of the first number from the network entity 102. For example, the measurement gap-related indication 204 may include N bit (s) to indicate whether to skip N measurement gap (s) after the DCI or not. The number N may equal to one. Alternatively, the number N may be an integer larger than one. The number N may be configured by a RRC parameter from the network entity 102 or predefined. In an example, the bit value of “0” may indicate not to skip the corresponding measurement gap and data cannot be transmitted in the measurement gap; and the bit value “1” may indicate to skip the corresponding measurement gap and data could be transmitted in the measurement gap. Some examples of the present disclosure are exemplified with such setting of bit values. It should be understood that the bit values can be set to the contrary, i.e., “1” indicating not skipping the measurement gap and “0” indicating skipping the measurement gap.
[0154] In some embodiments, the at least one measurement gap may be the first at least one measurement gap after the time offset threshold is elapsed from an ending symbol of the DCI. In other words, the gap between the starting symbol of the at least one measurement gap and the ending symbol of the DCI may be larger than or equal to the time offset threshold. The time offset threshold may be configured by the network entity 102 or may be predefined. The UE 104 may determine whether to skip the measurement gap based on the DCI. In other words, if the DCI indicates to skip a measurement gap, then the UE may determine to skip the measurement gap; and if the DCI indicates not to skip a measurement gap, then the UE may determine not to skip the measurement gap.
[0155] FIG. 3A illustrates an example diagram of a DCI carrying an indication for at least one measurement gaps in accordance with some example embodiments of the present disclosure. In the example of FIG. 3A, the DCI 301 may carry an indication including two bits to indicate whether to skip two measurement gaps (MGs) or not. MG 312 and MG 313 are the first two measurement gaps after the time offset threshold T is elapsed from an ending symbol of the DCI. In other words, MG 312 and MG 313 are the first two measurement gaps with a time gap between the starting symbol of the two MGs and the ending symbol of the DCI being larger than or equal to the time offset threshold T. The gap between the starting symbol of MG 311 and the ending symbol of the DCI 301 is smaller than the time offset threshold T and thus MG 311 is not indicated by the DCI 301. The two bits in the DCI 301 may indicate whether to skip MG 312 and MG 313, respectively. In one example, the two bits have a value of “01” and the UE 104 may determine not to skip MG 312 and determine to skip MG 313. In another example, the two bits have a value of “10” and the UE 104 may determine to skip MG 312 and determine not to skip MG 313.
[0156] Turning back to FIG. 2, in some embodiments, the at least one measurement gap may be the first at least one measurement gap after an ending symbol of the DCI. In other words, there are no other measurement gaps between the ending symbol of the DCI and the measurement gap (s) indicated by the DCI. The at least one measurement gap comprises measurement gap (s) right after the DCI. In some implementations, if a time offset from the ending symbol of the DCI to a starting symbol of the measurement gap is shorter than the time offset threshold, and if the measurement gap-related indication is indicative of skipping the measurement gap, the measurement gap-related indication does not take effect. In other words, if the DCI indicates to skip a measurement gap, the DCI should precede the measurement gap and have a time offset with the measurement gap greater than or equal to the time offset threshold; otherwise, the indication in the DCI does not take effect.
[0157] Still referring to FIG. 3A, the DCI 301 may carry an indication including two bits to indicate whether to skip two MGs or not. The first two measurement gaps located after the DCI 301 are MG 311 and MG 312. The two bits in the DCI 301 may indicate whether to skip MG 311 and MG 312, respectively. The gap between the starting symbol of MG 311 and the ending symbol of the DCI 301 is smaller than the time offset threshold T and thus the indication for MG 311 does not take effect if MG 311 is indicated to be skipped in the DCI 301. In one example, the two bits have a value of “01” and the UE 104 may determine not to skip MG 311 and determine to skip MG 312. In another example, the two bits have a value of “10” , the UE 104 may determine not to skip MG 312 and the first bit “1” for MG 311 does not take effect.
[0158] Turning back to FIG. 2, in some scenarios, there may be multiple DCIs before a measurement gap. A solution is needed to determine whether to skip the measurement gap based on the multiple DCIs and the time offset threshold. In some embodiments, when receiving the measurement gap-related indication 204, the UE 104 may receive at least one measurement gap-related indication include the measurement gap-related indication 204 from the network entity 102 prior to the time offset threshold from a starting symbol of the measurement gap. Each measurement gap-related indication may include an indication indicative of whether to skip the measurement gap. When determining whether to skip the measurement gap, the UE 104 may determine to skip the measurement gap if a last measurement gap-related indication among the at least one measurement gap-related indication is indicative of skipping the measurement gap.
[0159] In other words, the UE 104 may determine to skip the measurement gap if a last measurement gap-related indication among at least one measurement gap-related indication is indicative of skipping the measurement gap. The at least one measurement gap-related indication may include the measurement gap-related indication and each measurement gap-related indication may include an indication indicative of whether to skip the measurement gap. The at least one measurement gap-related indication is prior to the time offset threshold from a starting symbol of the measurement gap. That is, a measurement gap should be skipped if the indication in the last DCI before the time offset threshold from a starting symbol of the measurement gap indicates skipping the measurement gap. In some implementations, the UE 104 does not expect that, among two DCIs prior to the time offset threshold from a starting symbol of the measurement gap, a first DCI indicates skipping the measurement gap while a second DCI after the first DCI indicates not skipping the measurement gap.
[0160] FIG. 3B illustrates an example diagram of multiple DCIs carrying indications for the same measurement gap in accordance with some example embodiments of the present disclosure. In the example of FIG. 3B, the UE may receive DCI 321, DCI 322, DCI 323, and DCI 324 prior to MG 331. The gaps between the starting symbol of MG 331 and the ending symbols of the DCI 321 and the DCI 322 are larger than the time offset threshold T, and the gaps between the starting symbol of MG 331 and the ending symbols of the DCI 323 and the DCI 324 are smaller than the time offset threshold T.
[0161] In some implementations, among DCI 321, DCI 322, DCI 323, and DCI 423, only DCI 321 and DCI 322 may indicate whether to skip MG 331 or not. The DCI 322 is the last DCI corresponding to MG 331. The UE may determine to skip MG 331 if the indication in the DCI 322 indicates skipping MG 331. For example, if the DCI 321 indicates not skipping MG 331 while the DCI 322 indicates skipping MG 331, whether MG 331 should be skipped is determined based on the DCI 322. In some embodiments, the UE does not expect that the DCI 321 indicates skipping MG 331 while the DCI 322 indicates not skipping MG 331.
[0162] In some implementations, DCI 321, DCI 322, DCI 323, and DCI 324 may all be used to indicate whether to skip MG 331 or not. The DCI 322 is the last DCI prior to the time offset threshold T from a starting symbol of MG 331. The UE may determine to skip MG 331 if the indication in the DCI 322 indicates skipping MG 331.
[0163] In some embodiments, in order to receive the measurement gap-related indication 204, the UE 104 may receive, from the network entity 102, the DCI scheduling a PDSCH transmission. In other words, the measurement gap-related indication 204 may be carried in the DCI scheduling the PDSCH transmission. The UE 104 may determine to skip the measurement gap if the PDSCH transmission is at least partially overlapped with the measurement gap. In other words, the measurement gap-related indication 204 may indicate to skip the gap (s) / restriction (s) by scheduling a PDSCH reception overlapping with a gap (s) / restriction (s) .
[0164] In some embodiments, the UE 104 may determine to transmit hybrid automatic repeat request-acknowledgement (HARQ-ACK) information corresponding to the PDSCH transmission. In other words, the UE 104 may transmit the HARQ-ACK information corresponding to the PDSCH transmission if the PDSCH transmission is received in a skipped measurement gap.
[0165] In some implementations, when determining to transmit the HARQ-ACK information corresponding to the PDSCH transmission, the UE 104 may determine to transmit a physical uplink control channel (PUCCH) transmission carrying the HARQ-ACK information corresponding to the PDSCH transmission even if the PUCCH transmission is at least partially overlapped with a measurement gap. In other words, if the DCI indicates that a PDSCH transmission could be transmitted in a measurement gap, the corresponding PUCCH transmission carrying HRAQ-ACK information of the PDSCH transmission could be transmitted too when the PUCCH transmission is overlapped with a measurement gap
[0166] FIG. 4A illustrates an example diagram of a PUCCH transmission corresponding to a PDSCH transmission in accordance with some example embodiments of the present disclosure. In the example in FIG. 4A, the DCI 401 may schedule the PDSCH transmission 421. The PDSCH transmission 421 is partially overlapped with MG 411, indicating that MG 411 should be skipped. The UE may receive the PDSCH transmission 421 and transmit the HARQ-ACK information 422 corresponding to the PDSCH transmission 421. If the PUCCH resource for the HARQ-ACK information 422 is at least partially overlapped with MG 412, the UE may determine to skip MG 412 and transmit a PUCCH transmission carrying the HARQ-ACK information 422 in MG 412.
[0167] Alternatively, when determining to transmit the HARQ-ACK information corresponding to the PDSCH transmission, the UE 104 may determine to defer the HARQ-ACK information corresponding to the PDSCH transmission to another PUCCH transmission if a PUCCH transmission carrying the HARQ-ACK information is at least partially overlapped with a measurement gap. In other words, if a PDSCH transmission is indicated to be transmitted, but if the corresponding measurement gap could not be used for transmitting the PUCCH transmission carrying HRAQ-ACK information of the PDSCH transmission, the HRAQ-ACK information could be deferred to another PUCCH.
[0168] In some embodiments, the UE 104 may receive, from the network entity 102, an indication of a maximum time gap for deferring the PUCCH transmission. In an example, a time gap between the PUCCH transmission and the another PUCCH transmission is no greater than the maximum time gap. In another example, a time gap between the PDSCH transmission and the another PUCCH resource is no greater than the maximum time gap. In other words, the maximum time gap for PUCCH differing may be configured by the network entity. The maximum time gap for PUCCH differing may be configured for the gap between the PDSCH transmission to the final resource used to transmit the PUCCH. Alternatively, the maximum time gap for PUCCH differing may be configured for the gap between the initial PUCCH transmission to the final resource used to transmit the PUCCH.
[0169] In some embodiments, PUSCH transmission (s) may be dynamically scheduled by an UL grant in a DCI, for example DCI format 0_1, the DCI may indicate the start and length indicator value (SLIV) by an index to a time domain resource allocation (TDRA) table. In some embodiments, PUSCH transmission (s) may correspond to a configured grant (CG) Type 1 or Type 2. The CG Type 1 PUSCH transmission may be semi-statically configured to operate upon the reception of higher layer parameter of configuredGrantConfig including rrc-ConfiguredUplinkGrant without the detection of an UL grant in a DCI. The CG Type 2 PUSCH transmission may be semi-persistently scheduled by an UL grant in a valid activation DCI after the reception of higher layer parameter configuredGrantConfig not including rrc-ConfiguredUplinkGrant. The UE may be configured with one or multiple CG configurations, and for each CG configuration, a period P and the CG type may be provided
[0170] In some embodiments, the measurement gap-related indication 204 may be carried in the DCI scheduling a PUSCH transmission. The UE 104 may determine to skip the measurement gap if the PUSCH transmission is at least partially overlapped with the measurement gap. In other words, the measurement gap-related indication 204 may indicate to skip the gap (s) / restriction (s) by scheduling a PUSCH transmission overlapping with a gap (s) / restriction (s) .
[0171] In some embodiments, the UE 104 may determine to transmit information of a PUCCH transmission multiplexed in the PUSCH transmission if the PUCCH transmission is at least partially overlapped with the measurement gap. In other words, if a UL DCI indicates that a PUSCH transmission at least partially overlapped with a measurement gap could be transmitted and a PUCCH transmission is also at least partially overlapped with the measurement gap, information of the PUCCH transmission could be transmitted by multiplexing the information of the PUCCH transmission on the PUSCH transmission. In some implementations, the PUCCH transmission may carry HRAQ-ACK information of a PDSCH transmission received in a measurement gap. For example, the UE may receive a first DCI scheduling a PDSCH transmission at least partially overlapped with a first measurement gap, and then receive a second DCI scheduling a PUSCH transmission at least partially overlapped with a second measurement gap. If a PUCCH transmission carrying HRAQ-ACK information of the PDSCH transmission is overlapped with the second measurement gap, the HRAQ-ACK information may be multiplexed on the PUSCH transmission. Alternatively, the PUCCH transmission may be various types of PUCCH transmission. In other words, any PUCCH transmission may be multiplexed on the PUSCH transmission if the PUCCH transmission is overlapped with the measurement gap.
[0172] Alternatively, the UE 104 may determine to transmit a PUCCH transmission if the PUCCH transmission has a same priority as or a higher priority than the PUSCH transmission even if the PUCCH transmission is at least partially overlapped with a measurement gap. In other words, if a UL DCI indicates that a PUSCH transmission at least partially overlapped with a measurement gap could be transmitted, the PUCCH transmission with a same priority as the PUSCH transmission or with a higher priority than the PUSCH transmission should also be transmitted even if the PUCCH transmission is overlapped with a measurement gap. In some implementations, the PUCCH transmission may carry HRAQ-ACK information of a PDSCH transmission received in a measurement gap. Alternatively, the PUCCH transmission may be various types of PUCCH transmission. In other words, any PUCCH transmission with a same priority as the PUSCH transmission or with a higher priority than the PUSCH transmission may be transmitted even if the PUCCH transmission is overlapped with a measurement gap.
[0173] FIG. 4B illustrates an example diagram of a PUCCH transmission in a measurement gap in accordance with some example embodiments of the present disclosure. In the example in FIG. 4B, the DCI 431 may schedule the PUSCH transmission 451. The PUSCH transmission 451 is partially overlapped with MG 441, indicating that MG 441 should be skipped. The PUCCH transmission 452 is at least partially overlapped with MG 442. If the PUCCH transmission 452 has a same priority as the PUSCH transmission 451 or has a higher priority than the PUSCH transmission 451, the UE may determine to skip MG 442 and transmit the PUCCH transmission 452 in MG 442.
[0174] Turning back to FIG. 2, in some embodiments, the measurement gap-related indication 204 may be carried in the DCI scheduling a HRAQ-ACK retransmission in a PUCCH transmission or a one-shot HARQ-ACK codebook in a PUCCH transmission. The UE 104 may determine to skip the measurement gap if the PUCCH transmission is at least partially overlapped with the measurement gap. In other words, a DCI without scheduling PDSCH or PUSCH could also be used to indicate whether a PUCCH should be transmitted. The DCI could be a DCI schedule a HARQ-ACK retransmission, or one-shot HARQ-ACK codebook. In some implementations, the PUCCH transmission may carry HRAQ-ACK information of a PDSCH transmission received in a measurement gap. Alternatively, the PUCCH transmission may be various types of PUCCH transmission.
[0175] In some embodiments, the measurement gap-related indication 204 may be carried in the RRC parameter associated with a PUCCH transmission and may be indicative of whether to perform a measurement gap skipping if the PUCCH transmission is at least partially overlapped with a measurement gap. In other words, each PUCCH transmission may be configured with a respective indication of whether to skip an overlapping MG or not in a respective RRC parameter. In some implementations, the PUCCH transmission may carry HRAQ-ACK information of a PDSCH transmission received in a measurement gap. Alternatively, the PUCCH transmission may be various types of PUCCH transmission.
[0176] The second specific aspect is how to define the reference point for the time offset threshold if DCI repetitions are received. In some scenarios, the DCI used to indicate whether to skip a measurement or not may be repeated in two or multiple PDCCH occasions.
[0177] In some embodiments, the measurement gap-related indication 204 may be carried in multiple DCI repetitions. When determining whether to skip the measurement gap, the UE 104 may determine whether to skip the measurement gap indicated by the multiple DCI repetitions based on a time domain location of the first DCI repetition among the multiple DCI repetitions. In other words, the DCI may be transmitted in multiple bundled PDCCH candidates / occasions. That is, the DCI could be transmitted in a PDCCH with multiple repetitions.
[0178] In some embodiments, the measurement gap-related indication 204 may be indicative of whether to skip at least one measurement gap located after the first DCI repetition. The at least one measurement gap may include the measurement gap. In other words, the UE 104 may receive multiple DCI repetitions carrying the measurement gap-related indication 204 from the network entity 102 to indicate whether one or more measurement gaps after the first DCI should be skipped or not. That is, the indication in the DCI may be used to indicate the N measurement gap (s) after the first PDCCH occasion / repetition / candidate.
[0179] In some embodiments, the at least one measurement gap may be the first at least one measurement gap after the time offset threshold is elapsed from an ending symbol of the first DCI repetition. In other words, the gap between the starting symbol of the at least one measurement gap and the ending symbol of the first DCI repetition may be larger than or equal to the time offset threshold. FIG. 5A illustrates an example diagram of two DCI repetitions carrying indications for the measurement gap in accordance with some example embodiments of the present disclosure. In the example of FIG. 5A, the first DCI repetition 501 and the second DCI repetition 502 may indicate to skip MG 511. The gap between the starting symbol of the MG 511 and the ending symbol of the first DCI repetition 501 is larger than or equal to the time offset threshold T.
[0180] Turning back to FIG. 2, in some embodiments, the at least one measurement gap is the first at least one measurement gap after an ending symbol of the first DCI repetition. In other words, there are no other measurement gaps between the ending symbol of the first DCI repetition and the measurement gap (s) indicated by the DCI repetitions.
[0181] In some embodiments, if a time offset from the ending symbol of the first DCI repetition to a starting symbol of the measurement gap is shorter than the time offset threshold, and if the measurement gap-related indication 204 is indicative of skipping the measurement gap, the measurement gap-related indication 204 does not take effect. In other words, if the DCI repetitions indicate to skip a measurement gap, the first DCI repetition should precede the measurement gap and have a time offset with the measurement gap greater than or equal to the time offset threshold; otherwise, the indication in the DCI repetitions does not take effect.
[0182] Alternatively, when determining whether to skip the measurement gap, the UE 104 may determine whether to skip the measurement gap indicated by the multiple DCI repetitions based on a time domain location of the last DCI repetition among the multiple DCI repetitions. That is, the indication in the DCI may be used to indicate the N measurement gap (s) after the last PDCCH occasion / repetition / candidate.
[0183] In some embodiments, the measurement gap-related indication 204 may be indicative of whether to skip at least one measurement gap located after the last DCI repetition. The at least one measurement gap may include the measurement gap. In other words, the UE 104 may receive multiple DCI repetitions carrying the measurement gap-related indication 204 from the network entity 102 to indicate whether one or more measurement gaps after the last DCI should be skipped or not.
[0184] In some embodiments, the at least one measurement gap may be the first at least one measurement gap after the time offset threshold is elapsed from an ending symbol of the last DCI repetition. In other words, the gap between the starting symbol of the at least one measurement gap and the ending symbol of the last DCI repetition may be larger than or equal to the time offset threshold. FIG. 5B illustrates another example diagram of two DCI repetitions carrying indications for the measurement gap in accordance with some example embodiments of the present disclosure. In the example of FIG. 5B, the first DCI repetition 521 and the second DCI repetition 522 may indicate to skip MG 531. The gap between the starting symbol of the MG 531 and the ending symbol of the second DCI repetition 522 is larger than or equal to the time offset threshold T.
[0185] Turning back to FIG. 2, in some embodiments, the at least one measurement gap is the first at least one measurement gap after an ending symbol of the last DCI repetition. In other words, there are no other measurement gaps between the ending symbol of the last DCI repetition and the measurement gap (s) indicated by the DCI repetitions.
[0186] In some embodiments, if a time offset from the ending symbol of the last DCI repetition to a starting symbol of the measurement gap is shorter than the time offset threshold, and if the measurement gap-related indication 204 is indicative of skipping the measurement gap, the measurement gap-related indication 204 does not take effect. In other words, if the DCI repetitions indicate to skip a measurement gap, the last DCI repetition should precede the measurement gap and have a time offset with the measurement gap greater than or equal to the time offset threshold; otherwise, the indication in the DCI repetitions does not take effect.
[0187] The third specific aspect is how to configure the pattern via a RRC parameter to indicate occasions where to skip gaps / restrictions.
[0188] In some embodiments, the UE 104 may determine multiple reference measurement gaps. The measurement gap-related indication 204 may include a second number of bits, and each bit among the second number of bits is indicative of whether to perform a measurement gap skipping for a corresponding reference measurement gap among a second number of reference measurement gaps of multiple reference measurement gaps. For example, the measurement gap-related indication 204 may be carried in a RRC parameter and may include a N-bit bitmap. With such bitmap, a pattern to indicate occasions where to skip gaps / restrictions may be configured. Each bit among the N bits may be used to indicate whether a reference measurement gap should be skipped or not. Alternatively, each bit among the N bits may be used to indicate whether a group of reference measurement gaps should be skipped or not. There may be M reference measurement gaps in each group. M may be configured by the network entity 102 or may be predefined. M may be an integer equal to or larger than one. Some embodiments of the present disclosure are illustrated based on each bit corresponds one reference measurement gap, it should be understood that each bit may correspond to a group of reference measurement gaps in these embodiments. In an example, the bit value of “0” may indicate that the corresponding reference measurement gap (or reference measurement gap group) cannot be skipped and data cannot be transmitted in the reference measurement gap. The bit value “1” may indicate that the corresponding reference measurement gap can be skipped and data can be transmitted in the reference measurement gap. It should be understood that the bit values of the bitmap can be set to the contrary, i.e., “1” indicating not skipping the reference measurement gap and “0” indicating skipping the reference measurement gap.
[0189] In some embodiments, the UE 104 may receive, from the network entity 102, at least one measurement gap configuration for determining multiple measurement gaps. The UE 104 may determine the multiple reference measurement gaps based on a measurement gap configuration among the at least one measurement gap configuration. In some implementations, an indication of an identification (ID) of the measurement gap configuration is received from the network entity 102. In other words, the reference measurement gaps for the bitmap may be one of the measurement gap configurations provided by the network entity 102 and the UE 104 may receive the ID of the measurement gap configuration to be used for determining reference measurement gaps. Alternatively, the measurement gap configuration may have a smallest identification among the at least one measurement gap configuration. In other words, the UE 104 may use a default measurement gap configuration with a smallest ID for determining reference measurement gaps.
[0190] In some embodiments, the UE 104 may determine the multiple reference measurement gaps based on a length of a reference measurement gap, a period for the multiple reference measurement gaps and an offset of a first reference measurement gap among the multiple reference measurement gaps. The UE 104 may receive an indication of the length, the period and the offset from the network entity 102. In other words, the UE 104 may be configured with a reference length, a period and an offset for determining reference measurement gaps.
[0191] In some embodiments, the UE 104 may determine to skip the measurement gap if the measurement gap is at least partially overlapped with a reference measurement gap and if the bit is indicative of performing a measurement gap skipping for the reference measurement gap. In other words, if an actual measurement gap is at least partially overlapped with the reference measurement gap that is indicated to be skipped, the actual measurement gap should be fully skipped and a transmission / reception overlapped with the actual measurement gap may be transmitted or received.
[0192] FIG. 6A illustrates an example diagram of a bitmap indication based on reference measurement gaps in accordance with some example embodiments of the present disclosure. In the example in FIG. 6A, reference measurement gaps 601, 602, 603 and 604 are determined. The reference measurement gaps may be periodic with a periodicity of four reference measurement gaps. A pattern of “not-skip, not-skip, skip, skip” is indicated with a bitmap of “0011” . The reference measurement gaps 603 and 604 are indicated to be skipped. The real measurement gaps 611, 612 and 613 may be determined based on the same or different measurement gap configurations. The real measurement gaps 612 and 613 are overlapped with the reference measurement gaps 603 and 604 and thus are determined to be skipped. A transmission or reception overlapped with the measurement gaps 612 and 613 should be transmitted or received.
[0193] Turning back to FIG. 2, in some embodiments, the UE 104 may determine to skip a portion of the measurement gap if the portion of the measurement gap is overlapped with a reference measurement gap and if the bit is indicative of performing a measurement gap skipping for the reference measurement gap. In other words, if an actual measurement gap is partially overlapped with the reference measurement gap that is indicated to be skipped, the overlapped portion of the actual measurement gap should be skipped and a transmission / reception overlapped with the overlapped portion of the actual measurement gap may be transmitted or received.
[0194] In some embodiments, a transmission or a reception is scheduled to be at least partially overlapped with the measurement gap. The UE 104 may determine to perform the scheduled transmission or the scheduled reception if the scheduled transmission or the scheduled reception is at least partially overlapped with a reference measurement gap and if the bit is indicative of performing a measurement gap skipping for the reference measurement gap. If the UE 104 determines to perform the scheduled transmission or the scheduled reception, the UE 104 may determine to skip the measurement gap. In other words, a transmission or reception at least partially overlapped with the skipped reference measurement gap should be transmitted or received even if the transmission or reception is at least partially overlapped with an actual measurement gap.
[0195] In some embodiments, the UE 104 may receive at least one measurement gap configuration from the network entity 102 and determine multiple measurement gaps based on the measurement gap configuration. The measurement gap-related indication 204 may include a second number of bits, and each bit among the second number of bits is indicative of whether to perform a measurement gap skipping for a measurement gap among a second number of continuous measurement gaps among the multiple measurement gaps. In other words, the measurement gap-related indication 204 may be carried in a RRC parameter and may include a N-bit bitmap. Each bit among the N bits may be used to indicate whether an actual measurement gap should be skipped or not. The N-bit bitmap may correspond to N continuous actual measurement gaps in time domain determined based on at least one measurement gap configuration. Alternatively, each bit among the N bits may be used to indicate whether a group of actual measurement gaps should be skipped or not. There may be M actual measurement gaps in each group. M may be configured by the network entity 102 or may be predefined. M may be an integer equal to or larger than one. Some embodiments of the present disclosure are illustrated based on each bit corresponds one actual measurement gap, it should be understood that each bit may correspond to a group of actual measurement gaps in these embodiments.
[0196] FIG. 6B illustrates an example diagram of a bitmap indication based on actual measurement gaps in accordance with some example embodiments of the present disclosure. In the example in FIG. 6B, measurement gaps 621 to 628 are determined based on the same or different measurement gap configurations. A pattern of “not-skip, not-skip, skip, skip” is indicated with a bitmap of “0011” . The measurement gaps 623, 624, 627 and 628 may be determined to be skipped based on the pattern. A transmission or reception overlapped with the measurement gaps 623, 624, 627 and 628 should be transmitted or received.
[0197] The fourth specific aspect is how to determine which indication / parameter to use and how to handle the collisions, if any, if both the pattern via a RRC parameter and the DCI indication can be used to indicate occasions where to skip gaps / restrictions.
[0198] In some embodiments, if the measurement gap-related indication 204 is carried in the DCI while not carried in a RRC parameter, the UE 104 may determine whether to perform a measurement gap skipping based on the DCI. In other words, if only the DCI is configured to provide the measurement gap-related indication, the UE 104 may determine whether to perform a measurement gap skipping based on the DCI, e.g., based on the embodiments in the first and second specific aspects.
[0199] In some embodiments, if the measurement gap-related indication 204 is carried in the RRC parameter while not carried in a DCI, the UE 104 may determine whether to perform a measurement gap skipping based on the RRC parameter. In other words, if only the pattern is configured with the RRC parameter to provide the measurement gap-related indication, the UE 104 may determine whether to perform a measurement gap skipping based on the pattern, e.g., based on the embodiments in the third specific aspect.
[0200] In some embodiments, if the measurement gap-related indication 204 is carried in the DCI and the RRC parameter, the UE 104 may determine whether to perform a measurement gap skipping based on a further RRC parameter indicative of whether to use the DCI or the RRC parameter or both to determine whether to perform a measurement gap skipping. In other words, if both the DCI and the pattern are configured to provide the measurement gap-related indication, the UE 104 may receive a RRC parameter indicative of which one or both of the DCI and the pattern should be used for determining whether to perform a measurement gap skipping.
[0201] Alternatively, if the measurement gap-related indication 204 is carried in the DCI and the RRC parameter, the UE 104 may determine whether to perform a measurement gap skipping based on both the DCI and the RRC parameter.
[0202] In some implementations, an indication of whether to skip the measurement gap carried in the DCI and an indication of whether to skip the measurement gap carried in the RRC parameter are the same. In other words, the UE does not expect that for the same measurement gap, one among the DCI and the RRC parameter indicates not skipping the measurement gap, but the other indicates skipping the measurement gap.
[0203] In some implementations, an indication of whether to skip the measurement gap carried in the DCI follows as an indication of whether to skip the measurement gap carried in the RRC parameter. In other words, the UE does not expect that for the same measurement gap, the indication in DCI is different from the indication in the RRC parameter.
[0204] In some implementations, the DCI indicates skipping the measurement gap if the RRC parameter indicates skipping the measurement gap, or the DCI indicates skipping or not skipping the measurement gap if the RRC parameter indicates not skipping the measurement gap or if the RRC parameter does not indicate whether to skip the measurement gap or not. In other words, the UE does not expect for the same measurement gap, the RRC parameter indicates skipping, but the DCI indicates not skipping. The DCI could only be used to indicate to skip the measurement gap that is indicated not skipping by the RRC parameter or to indicate to skip the measurement gap not indicated by RRC.
[0205] FIG. 7A illustrates a first example diagram of a determination based on both a DCI and a pattern in accordance with some example embodiments of the present disclosure. In the example in FIG. 7A, measurement gaps 721 to 728 are determined based on the same or different measurement gap configurations. A pattern of “not-skip, not-skip, skip, skip” is indicated with a bitmap of “0011” . The measurement gaps 723, 724, 727 and 728 may be determined to be skipped based on the pattern. The measurement gap 722 is determined to be not skipped based on the pattern. If a DCI 710 is received indicating to skip the measurement gap 722 and the gap between the starting symbol of the measurement gap 722 and the ending symbol of the DCI 710 is larger than or equal to the time offset threshold, then the measurement gap 722 may be determined to be skipped.
[0206] FIG. 7B illustrates a second example diagram of a determination based on both a DCI and a pattern in accordance with some example embodiments of the present disclosure. In the example in FIG. 7B, reference measurement gaps 731, 732, 733 and 734 are determined. The reference measurement gaps may be periodic with a periodicity of four reference measurement gaps. A pattern of “not-skip, not-skip, skip, skip” is indicated with a bitmap of “0011” . The reference measurement gaps 733 and 734 are indicated to be skipped. The real measurement gaps 741 to 745 may be determined based on the same or different measurement gap configurations. The real measurement gaps 743 and 745 are overlapped with the reference measurement gaps 733 and 734 and thus are determined to be skipped based on the pattern. The real measurement gap 744 not overlapped with any reference measurement gap and thus is not configured whether to skip by the pattern. If a DCI 750 is received indicating to skip the measurement gap 744 and the gap between the starting symbol of the measurement gap 744 and the ending symbol of the DCI 750 is larger than or equal to the time offset threshold, then the measurement gap 744 may be determined to be skipped based on the DCI 750.
[0207] In some implementations, whether to skip the measurement gap is determined based on the DCI if an indication of whether to skip the measurement gap carried in the DCI is different from an indication of whether to skip the measurement gap carried in the RRC parameter. In other words, if the measurement gap-related indication in the DCI and the measurement gap-related indication in the RRC parameter for the same measurement gap are different, the UE may follow the measurement gap-related indication in the DCI.
[0208] FIG. 7C illustrates a third example diagram of a determination based on both a DCI and a pattern in accordance with some example embodiments of the present disclosure. In the example in FIG. 7C, measurement gaps 761 to 768 are determined based on the same or different measurement gap configurations. A pattern of “not-skip, not-skip, skip, skip” is indicated with a bitmap of “0011” . The measurement gaps 763, 764, 767 and 768 may be determined to be skipped based on the pattern. If a DCI 770 is received indicating not to skip the measurement gap 763 and the gap between the starting symbol of the measurement gap 763 and the ending symbol of the DCI 770 is larger than or equal to the time offset threshold, then the measurement gap 763 may be determined to be not skipped based on the DCI 770.
[0209] In some implementations, whether to skip the measurement gap is determined based on the RRC parameter if an indication of whether to skip the measurement gap carried in the DCI is different from an indication of whether to skip the measurement gap carried in the RRC parameter. In other words, if the measurement gap-related indication in the DCI and the measurement gap-related indication in the RRC parameter for the same measurement gap are different, the UE may follow the measurement gap-related indication in the RRC parameter.
[0210] In some implementations, the measurement gap is determined to be skipped if at least one of the DCI or the RRC parameter indicates skipping the measurement gap. In other words, the UE may determine to skip a measurement gap, if any signaling, either the DCI or the RRC parameter, indicates to skip the measurement gap.
[0211] In some implementations, the measurement gap is determined to be skipped only if both the DCI and the RRC parameter indicate skipping the measurement gap. In other words, the UE may determine to skip a measurement gap, only if both the DCI and the RRC parameter indicate to skip the measurement gap.
