Description

[Technical Field]

[0001] Various embodiments relate to devices, methods, apparatus, and computer-readable media for configured grant (CG) activation. [Background technology]

[0002] Currently, activation and deactivation of CG resources, such as CG-Physical Uplink Shared Channel (PUSCH) resources, can be controlled by the network side. There are two types of CG resources: For CG Type-1, the configuration and deconfiguration of CG resources can be provided by the network side via Radio Resource Control (RRC) signaling without Physical Downlink Control Channel (PDCCH) activation and deactivation. For CG Type-2, the configuration and deconfiguration of CG resources can be provided via RRC, while activation and deactivation for CG with physical resource block (PRB) resources, modulation and coding scheme (MCS), etc. can be provided via PDCCH addressed to the configured scheduling radio network temporary identifier (CS-RNTI). However, because the network side typically has limited visibility into the data in the user equipment (UE) buffer, primarily based on received buffer status reports (BSRs), it can be difficult for the network side to determine whether and / or when deactivation is appropriate, or whether deactivation may incur a latency penalty for the UE. While CG-based operation is primarily specified for deterministic and regular traffic types, real-world traffic may be less regular in practice due to application behavior and jitter effects. For this reason, the UE may skip CG-PUSCH opportunities if no data is present. However, the network side is unaware of such skipping and therefore must still perform unnecessary reception monitoring.

[0111] Throughout the drawings, the same or similar reference numerals refer to the same or similar elements, and repeated description of the same elements will be omitted.

[0112] Hereinafter, several exemplary embodiments will be described in detail with reference to the accompanying drawings. The following description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some cases, well-known circuits, techniques, and components are shown in block diagram form to avoid obscuring the described concepts and features.

[0113] The exemplary embodiments of the present disclosure provide a solution for CG activation. According to the exemplary embodiments of the present disclosure, the CG resource type can be activated by the UE. The network side can strengthen reception monitoring when uplink data exists or when an indication is received from the UE, which allows the reception level on the network side to be kept low, thereby saving energy on the network side.

[0114] 1 to 3 show example sequence diagrams of CG activation in accordance with various example embodiments of the present disclosure. Referring to FIG. 1 to 3, UE 110 may represent any terminal device in a wireless communication network, and network device 120 may function as a base station (BS), e.g., a next generation Node B (gNB), in the wireless communication network and provide service to UE 110 as a serving cell.

[0115] 1 to 3, network device 120 may transmit configuration information 130 of CG resources to UE 110. Configuration information 130 may be configured by network device 120, or network device 120 may receive configuration information 130 from another network device. CG resources may include, for example, CG PUSCH resources. Furthermore, CG resources may be of a type different from CG Type-1 and CG Type-2, and the type of CG resource may be indicated, for example, as CG Type-3. In various exemplary embodiments, CG resources may be activated by the UE side, for example, UE 110. Configuration information 130 may be transmitted to UE 110, for example, via RRC signaling.

[0116] After transmitting the configuration information 130, in operation 135, the network device 120 may enter a sleep mode, eg, discontinuous transmission (DTX), to conserve power consumption of the network device 120.

[0117] On the UE side, with configuration information 130 of the CG resources, UE 110 may determine to activate the CG resources in operation 140. For example, if UE 110 needs PUSCH resources to perform uplink transmission, UE 110 may determine to activate the CG resources in operation 140. In one embodiment, UE 110 may determine to activate the CG resources if it reports a non-empty BSR, which may indicate that there is data in the buffer to be transmitted. In this disclosure, a CG resource may be a generic term and may refer to one or more CG resources, and similarly, a transmission using a CG resource may also be a generic term and may refer to one or more transmissions through a CG resource.

[0118] Optionally, UE 110 may then transmit an indication 145 indicating to activate the CG resources to network device 120. For example, network device 120 may receive the indication 145 via at least one of the following: a dedicated scheduling request (SR), a dedicated random access (RA) preamble, a dedicated uplink control information (UCI), or a PUSCH.

[0119] The dedicated SR, dedicated RA preamble, and dedicated UCI may be, for example, Layer 1 (L1) signaling. In one embodiment, the UE 110 may be explicitly configured, for example, via configuration information 130, whether a CG resource with a shorter periodicity, e.g., a CG Type-3 resource, may be autonomously activated by another UL transmission with a longer periodicity. The CG with a longer periodicity may be, for example, a CG Type-1 PUSCH or a CG Type-2 PUSCH. The CG Type-3 resource may be autonomously activated by the UE 110 based on the other UL transmission.

[0120] For example, the PUSCH carrying the indication 145 may be a CG PUSCH with a longer periodicity than the activated CG resources. The CG PUSCH carrying the indication 145 may be, for example, a CG Type-1 or CG Type-2. In this case, if the network device 120 does not receive an uplink transmission on a CG PUSCH with infrequent resources, such as a CG Type-1 PUSCH or a CG Type-2 PUSCH, the network device 120 may enter a sleep state until the next CG PUSCH with infrequent resources. When the network device 120 receives an uplink transmission on a CG PUSCH with infrequent resources, such as a CG Type-1 PUSCH or a CG Type-2 PUSCH, the network device 120 may be activated by the UE 110 and begin monitoring more frequent CG resources, which may be, for example, CG Type-3 resources. Thus, the resources that have not yet been activated may be allocated to other UEs before the UE 110 begins using them. This allows the network side to keep the reception level at a minimum, thereby saving energy and increasing the reception level when uplink data is present. Optionally, if the buffer of UE 110 becomes empty after a transmission over a CG PUSCH with infrequent resources, network device 120 may enter a sleep mode until the next CG PUSCH with infrequent resources without receiving a non-empty BSR.

[0121] In one embodiment, in operation 140, UE 110 may determine to activate at least one opportunity for using the CG resource. The at least one opportunity may be, for example, one or more consecutive CG PUSCH opportunities, for example, over a specific time or number of opportunities. In this case, indication 145 may include the specific time or number of opportunities. Alternatively, the time or number of opportunities may also be set by network device 120. After the end of the at least one opportunity for using the CG resource, the CG resource may be implicitly deactivated.

[0122] Alternatively, in one embodiment, after UE 110 decides to activate CG resources in operation 140, UE 110 may use the activated CG resources until it receives signaling 170 explicitly deactivating the CG resources from network device 120. In this case, UE 110 may stop transmissions to network device 120 using the activated CG resources when it receives signaling 170 from network device 120 deactivating the CG resources.

[0123] In one embodiment, UE 110 may be configured, for example, by configuration information 130, as to whether UE 110 is permitted to begin using the activated CG resources directly after sending indication 145, or whether UE 110 requires a response from network device 120 before using the activated CG resources.

[0124] In one embodiment, UE 110 is permitted to directly use the activated CG resources after sending indication 145. In this embodiment, UE 110 may perform transmission 155 to network device 120 using the activated CG resources after transmitting indication 145 without receiving a response confirming the activation from network device 120. As shown in FIG. 1 , UE 110 may perform transmission 155 to network device 120 using the activated CG resources without a response from network device 120.

[0125] In one embodiment, the UE 110 may perform transmission 155 using the activated CG resource without transmitting an indication 145. The transmission 155 itself may implicitly indicate that the CG resource has been activated.

[0126] In one embodiment, UE 110 may perform transmission 155 to network device 120 after an activation delay period 132 beginning with transmission of indication 145. For example, a period of time may be required before network device 120 is ready to receive transmission 155. For example, if network device 120 enters sleep mode in operation 135, network device 120 may transition out of sleep mode in operation 150 upon receiving indication 145.

[0127] The activation delay period 132 may be predefined in a specification or standard. Alternatively, the network device 120 may set the activation delay period 132 to ensure that the network device 120 has sufficient time to wake up to receive transmissions 155 over the activated CG resources. For example, the network device 120 may set the activation delay period 132 according to different sleep levels or sleep states of the network device 120. A longer activation delay period 132 may be configured for a deeper sleep state requiring a longer transition duration. In this case, the activation delay period 132 may be included in the configuration information 130. The activation delay period 132 begins when the UE 110 transmits the indication 145, and after the activation delay period 132, transmissions 155 over the activated CG resources may be allowed.

[0128] Alternatively, the activation delay period 132 may be determined by the UE 110 based on a predetermined condition. In one embodiment, the predetermined condition may be associated with the periodicity of at least one of the following: a synchronization signal block (SSB) or a reference signal (RS). For example, if the network device 120 changes the period of other signals, such as an SSB or RS, to be longer, the UE 110 may determine to make the activation delay period 132 longer.

[0129] In one embodiment, the first opportunity for transmission 155 using the configured grant resource may be after the activation delay period 132. For example, the UE 110 may determine that the first opportunity for transmission 155 is after the activation delay period 132 so that unnecessary transmissions 155 may be avoided.

[0130] On the network side, network device 120 may begin monitoring for the activated CG resource in operation 160. As shown in FIG. 1, network device 120 may perform operation 160 after transitioning from sleep mode in operation 150. If network device 120 does not perform operation 135 to enter sleep mode, network device 120 may perform operation 160 after receiving indication 145.

[0131] In some exemplary embodiments, UE 110 may transmit on the activated CG resource at the first one or more opportunities for the activated CG resource, but may not further utilize the up-source until it receives a response confirming activation indication 145.

[0132] For example, referring to FIG. 3, transmission 155 in FIG. 1 may be divided into transmission 355 and transmission 365. Transmission 355 may be performed, for example, on the first one or more occasions of activating CG resources without confirmation of activation indication 145. In this case, network device 120 may begin monitoring for reception of activated CG resources after transitioning from sleep mode in operation 150. If network device 120 does not perform operation 135 because it enters sleep mode, network device 120 may perform operation 160 after receiving indication 145. Transmission 365 may be performed for activated CG resources opportunities after the first one or more occasions, for example, after receiving a first response 360 confirming activation of transmission 365 using the CG resources.

[0133] In this embodiment, the UE 110 may perform transmission 355 using the activated CG resource without transmitting an indication 145. The transmission 355 itself may implicitly indicate that the CG resource is activated.

[0134] In one embodiment, the UE 110 may refrain from performing transmission 365 if it does not receive the first response 360 within a first checking period. The first checking period may begin with performing transmission 355. The first checking period may be predefined in a specification or standard or may be set by the network device 120.

[0135] In one embodiment, whether the first response 360 is required for a transmission 365 using the CG resource after the first one or more opportunities may be predefined in a specification or standard. Alternatively, whether the first response 360 is required for a transmission 365 using the CG resource after the first one or more opportunities may be configured by the network device 120. For example, the configuration information 130 may include a confirmation indicator 332 to indicate to the UE 110 whether the first response 360 is required for a transmission 365. The number of the first one or more opportunities may also be predefined in a specification or standard. Alternatively, the number of the first one or more opportunities may also be configured by the network device 120. For example, the confirmation indicator 332 may indicate the number of the first one or more opportunities.

[0136] On the network side, if a first response 360 confirming the activation is required for transmission 365 using CG resources after the first one or more opportunities, network device 120 may transmit first response 360 confirming the activation to UE 110. The operation of confirming the activation may be performed in operation 160.

[0137] In some exemplary embodiments, UE 110 requires a response from network device 120 before using the activated CG resource. For example, UE 110 may perform transmission on the activated CG resource after receiving a response confirming activation indication 145.

[0138] 2, in response to the indication 145, the network device 120 may transmit a second response 260 to the UE 110 if it confirms the activation. In this case, operation 160 for initiating monitoring for receipt of the activated CG resources may be performed upon transmitting the second response 260. In one embodiment, the network device 120 may trigger the activation confirmation in operation 150. After the UE 110 receives the second response 260 confirming the activation, it may perform transmission 255 to the network device 120 using the activated CG resources.

[0139] In one embodiment, whether the second response 260 is required for a transmission 255 using a CG resource may be predefined in a specification or standard, or alternatively, whether the second response 260 is required for a transmission 255 using a CG resource may be configured by the network device 120.

[0140] In one embodiment, network device 120 may transmit second response 260 after a delay period beginning with receiving indication 145. The delay period may be predefined in a specification or standard. Alternatively, the delay period may be configured by network device 120. For example, network device 120 may configure a relaxed delay period to ensure sufficient time to exit a sleep mode, e.g., a current efficient DTX state, so that network device 120 may complete confirmation of CG resource activation during the delay period.

[0141] Optionally, network device 120 may transmit a delay period to UE 110 so that UE 110 may predict when to begin receiving the second response. UE 110 may monitor for second response 260 after the delay period beginning with transmitting indication 145. For example, configuration information 130 may include the delay period. In this case, the delay period may also be used as an indication that second response 260 is required for transmission 255 using CG resources.

[0142] In one embodiment, the UE 110 may refrain from transmitting 255 if it does not receive the second response 260 during the confirmation period 232. The confirmation period may begin with transmitting the indication 145. The confirmation period 232 may be predefined in a specification or standard or may be set by the network device 120.

[0143] Optionally, network device 120 may transmit a confirmation period 232 to UE 110 so that UE 110 may predict when to receive the second response. UE 110 may monitor for second response 260 during confirmation period 232, which begins with transmitting indication 145. For example, configuration information 130 may include confirmation period 232. In this case, confirmation period 232 may also be used as an indication that second response 260 is required for transmission 255 using CG resources.

[0144] In one embodiment, when UE 110 may use CG resources after receiving second response 260, e.g., via PDCCH DCI, L1 signaling indicating activation, e.g., indication 145, may be based on UL buffer status so that the correct resource block (RB) / MCS may be activated. For example, indication 145 may indicate the status of the uplink buffer so that second response 260 may indicate at least one of at least one RB or MCS. Based on the status of UE 110's uplink buffer, the appropriate RB and MCS may be determined by network device 120 and indicated to UE 110.

[0145] In one embodiment, the network device 120 may use a downlink feedback information (DFI) for the CG PUSCH, eg, a CG DFI, to convey the first response 360 or the second response 260.

[0146] Although various exemplary embodiments of the present disclosure are described with reference to Figures 1-3, it should be understood that operations and elements in different figures may be combined unless clearly contradictory. For example, transmission 355 may be performed by UE 110 after receiving second response 260.

[0147] According to various example embodiments of the present disclosure, CG resources may be activated by the UE, and the network side may increase reception monitoring when uplink data is present or when an indication 145 is received, so that a low level of reception monitoring may be performed, saving power on the network side.
