Description

DEVICES, METHODS, APPARATUSES, AND COMPUTER READABLE MEDIA FOR CONFIGURED GRANT ACTIVATION

TECHNICAL FIELD

Various embodiments relate to devices, methods, apparatuses, and computer readable media for configured grant (CG) activation.

BACKGROUND

Currently, activation and deactivation of a CG resource, e.g. CG-physical uplink shared channel (PUSCH) resource (s) may be controlled by network side. There have been two types of CG resources. For CG Type-1, configuration and de-configuration of the CG resource may 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 de-configuration of the CG resource may be provided via RRC whereas the activation and deactivation for the CG with physical resource block (PRB) resource, modulation and coding scheme (MCS) etc. may be provided via PDCCH addressed to configured scheduling radio network temporary identifier (CS-RNTI) . However, the network side usually has limited visibility on data in user equipment (UE) buffer, which is based primarily on the received buffer status report (BSR) , and therefore it may be challenging for the network side to determine whether and/or when the deactivation is suitable or whether the deactivation may cause latency penalties for the UE. CG based operation (s) is/are defined mainly for deterministic and regular traffic types, however, real life traffic may not be so regular in practice due to application behavior and jitter. For such reason, the UE may skip a CG-PUSCH occasion if no data is present. However, the network side is unaware of such skipping, and therefore it would nevertheless need to perform reception monitoring unnecessarily.

DETAILED DESCRIPTION

Herein below, some example embodiments are 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 instances, well known circuits, techniques and components are shown in block diagram form to avoid obscuring the described concepts and features.

Example embodiments of the present disclosure provide a solution for CG activation. According to the example embodiments of the present disclosure, a type of CG resource may be activated by the UE. The network side may increase reception monitoring upon presence of uplink data or receiving an indication from the UE, which allows to keep a low level of reception at the network side, thus saving energy at the network side.

FIG. 1 to FIG. 3 shows exemplary sequence diagrams for CG activation according to various example embodiments of the present disclosure. Referring to the FIG. 1 to the FIG. 3, a UE 110 may represent any terminal device in a wireless communication network, and a network device 120 may function as a base station (BS) , e.g. a next generation node-B (gNB) , in the wireless communication network and serve the UE 110 as a serving cell.

Referring to the FIG. 1 to the FIG. 3, the network device 120 may transmit configuration information 130 of a CG resource to the UE 110. The configuration information 130 may be configured by the network device 120, alternatively the network device 120 may receive the configuration information 130 from other network device (s) . The CG resource may comprise, for example, the CG PUSCH resource (s) . Moreover, the CG resource may be of a type different from the CG Type-1 and the CG Type-2, and the type of the CG resource may be denoted as, for example, CG Type-3. In the various example embodiments, the CG resource may be activated by the UE side, e.g. the UE 110. The configuration information 130 may be transmitted to the UE 110 via e.g. a RRC signaling.

After transmitting the configuration information 130, in an operation 135 the network device 120 may enter into a sleep mode, e.g., discontinuous transmission (DTX) , such that power consumption on the network device 120 may be saved.

On the UE side, with the configuration information 130 of the CG resource, in an operation 140, the UE 110 may determine to activate the CG resource. For example, if the UE 110 needs PUSCH resources to perform an uplink transmission, in the operation 140, the UE 110 may determine to activate the CG resource. In an embodiment, the UE 110 may determine to activate the CG resource in a case of reporting a non-empty BSR, which may indicate that there are data in the buffer to be transmitted. In the present disclosure, the CG resource may be a collective term and may refer to one or more CG resources, similarly, the transmission using the CG resource may also be a collective term and may refer to one or more transmissions over the CG resource (s) .

As an option, then, the UE 110 may transmit to the network device 120, an indication 145 indicative of activating the CG resource. For example, the 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, dedicated uplink control information (UCI) , or a PUSCH.

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

For example, the PUSCH carrying the indication 145 may be a CG PUSCH with periodicity longer than that of the CG resource being activated. The CG PUSCH carrying the indication 145 may be of for example the CG Type-1 or the CG Type-2. In this case, if the network device 120 does not receive uplink transmission on the CG PUSCH with less frequent resources such as the CG Type-1 PUSCH or the CG Type-2 PUSCH, the network device 120 may sleep until the next CG PUSCH with the infrequent resources. When the network device 120 receives the uplink transmission on the CG PUSCH with less frequent resources, such as the CG Type-1 PUSCH or the CG Type-2 PUSCH, the network device 120 may begin to listen to the CG resource which is activated by the UE 110 and is more frequent, which may be, for example, the CG Type-3 resource. Thus, the resources not yet activated may be allocated to other UEs before the UE 110 starts to use them. This allows to keep a minimum level of reception at the network side, thus saving energy, and increase the level of reception upon presence of uplink data. As an option, if the buffer of the UE 110 is emptied after the transmission over the CG PUSCH with the infrequent resources, the network device 120, without receiving the non-empty BSR, may enter into the sleep mode until the next CG PUSCH with the infrequent resources.

In an embodiment, in the operation 140, the UE 110 may determine to activate at least one occasion for using the CG resource. The at least one occasion may be for example one or more consecutive CG PUSCH occasions e.g. for a defined time or a number of occasions. In this case the indication 145 may include the defined time or the number of occasions. Alternatively, the time or the number of the occasions may also be configured by the network device 120. After the at least one occasion for using the CG resource, the CG resource may be implicitly deactivated.

Alternatively, in an embodiment, after the operation 140 in which the UE 110 determines to activate the CG resource, the UE 110 will use the activated CG resource before receiving a signaling 170 explicitly deactivating the CG resource from the network device 120. In this case, the UE 110 may stop the transmission to the network device 120 using the activated CG resource in case of receiving from the network device 120, the signaling 170 deactivating the CG resource.

In an embodiment, the UE 110 can be configured, e.g. via the configuration information 130, on whether the UE 110 is allowed to directly start to use the activated CG resource after sending the indication 145 or whether the UE 110 needs a response from the network device 120 before using the activated CG resource.

In an embodiment, the UE 110 is allowed to directly start to use the activated CG resource after sending the indication 145. In this embodiment, the UE 110 may perform a transmission 155 to the network device 120 using the activated CG resource after transmitting the indication 145 without a response from the network device 120 to confirm the activation. As is shown in the FIG. 1, the UE 110 may perform the transmission 155 to the network device 120 using the activated CG resource without the response from the network device 120.

In an embodiment, the UE 110 may perform the transmission 155 using the activated CG resource without transmitting the indication 145. The transmission 155 itself may implicitly indicate that the CG resource is activated.

In an embodiment, the UE 110 may perform the transmission 155 to the network device 120 after an activation delay period 132 starting from transmitting the indication 145. For example, it is possible that the network device 120 may need a period to be ready to receive the transmission 155. For example, if the network device 120 enters into the sleep mode in the operation 135, in an operation 150, the network device 120 may transit out of the sleep mode upon receiving the indication 145.

The activation delay period 132 may be predefined in a specification or a standard. Alternatively, the network device 120 may configure the activation delay period 132 to ensure that there is sufficient time for the network device 120 to wake up for receiving the transmission 155 over the activated CG resource. For example, the network device 120 may configure the activation delay period 132 according to different sleep levels or sleep states of the network device 120. Longer activation delay period 132 may be configured for deeper sleep states that require longer transition time duration. In this case, the activation delay period 132 may be included in the configuration information 130. The activation delay period 132 starts from the timing the UE 110 transmits the indication 145, and after the activation delay period 132, the transmission 155 on the activated CG resource may be allowed.

Alternatively, the activation delay period 132 may be determined by the UE 110 based on a predefined condition. In an embodiment, the predefined condition may be associated with 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 periodicity of other signals, such as the SSB, the RS, etc., to be longer, the UE 110 may determine the activation delay period 132 to be longer.

In an embodiment, an initial occasion for the transmission 155 using the configured grant resource may be after the activation delay period 132. For example, the UE 110 may determine the initial occasion for the transmission 155 to be after the activation delay period 132 such that the unnecessary transmission 155 may be avoided.

On the network side, in an operation 160, the network device 120 may initiate reception monitoring for the activated CG resource. As is shown in the FIG. 1, the network device 120 may perform the operation 160 after transiting out of the sleep mode in the operation 150. If the network device 120 does not perform the operation 135 to enter into the sleep mode, the network device 120 may perform the operation 160 after receiving the indication 145.

In some example embodiments, the UE 110 may perform the transmission on the activated CG resource on first one or more occasions for the activated CG resource, but may not utilize further resources until receiving a response confirming the activation indication 145.

For example, referring to the FIG. 3, the transmission 155 in the FIG. 1 may be divided into a transmission 355 and a transmission 365. The transmission 355 may be for example, performed on the first one or more occasions for the activated CG resource without a confirmation for the activation indication 145. In this case, the network device 120 may initiate reception monitoring for the activated CG resource after transiting out of the sleep mode in the operation 150. If the network device 120 does not perform the operation 135 to enter into the sleep mode, the network device 120 may perform the operation 160 after receiving the indication 145. The transmission 365 may be for example, performed on the occasions for the activated CG resource after receiving a first response 360 confirming the activation for the transmission 365 using the CG resource after the first one or more occasions.

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

In an embodiment, the UE 110 may refrain from performing the transmission 365 if without receiving the first response 360 during a first confirmation period. The first confirmation period may start from performing the transmission 355. The first confirmation period may be predefined in a specification or a standard or configured by the network deice 120.

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

On the network side, in a case where the first response 360 confirming the activation is required for the transmission 365 using the CG resource after the first one or more occasions, the network device 120 may transmit to the UE 110, the first response 360 in case of confirming the activation. The operation of confirming the activation may be performed in the operation 160.

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

For example, referring to the FIG. 2, in response to the indication 145, the network device 120 may transmit to the UE 110, a second response 260 in case of confirming the activation. In this case, the operation 160 to initiate the reception monitoring for the activated CG resource may be performed upon transmitting the second response 260. In an embodiment, the network device 120 may trigger the activation confirmation in the operation 150. The UE 110 may perform a transmission 255 to the network device 120 using the activated CG resource after receiving the second response 260 confirming the activation.

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

In an embodiment, the network device 120 may transmit the second response 260 after a delay period which starts from receiving the indication 145. The delay period may be predefined in a specification or a standard. Alternatively, the delay period may be configured by the network device 120. For example, the network device 120 may configure a relaxed delay period to allow enough time to exit the sleep mode, e.g. a current efficient DTX state, such that the network device 120 may complete the confirmation of the activation of the CG resource during the delay period.

As an option, the network device 120 may transmit the delay period to the UE 110 such that the UE 110 may estimate the timing for starting to receive the second response. The UE 110 may monitor the second response 260 after the delay period starting from transmitting the indication 145. For example, the configuration information 130 may include the delay period. In this case, the delay period may also be used as an indication that the second response 260 is required for the transmission 255 using the CG resource.

In an embodiment, the UE 110 may refrain from performing the transmission 255 if without receiving the second response 260 during a confirmation period 232. The confirmation period may start from transmitting the indication 145. The confirmation period 232 may be predefined in a specification or a standard or configured by the network deice 120.

As an option, the network device 120 may transmit the confirmation period 232 to the UE 110 such that the UE 110 may estimate the timing for receiving the second response. The UE 110 may monitor the second response 260 during the confirmation period 232 starting from transmitting the indication 145. For example, the configuration information 130 may include the confirmation period 232. In this case, the confirmation period 232 may also be used as an indication that the second response 260 is required for the transmission 255 using the CG resource.

In an embodiment, if the UE 110 can use the CG resource after receiving the second response 260 e.g. via PDCCH DCI, the L1 signaling indicating activation, e.g. the indication 145 may be based on the UL buffer status so that the right resource block (RB) /MCS may be activated. For example, the indication 145 may indicate an uplink buffer status, so that the second response 260 may indicate at least one of the following: at least one RB or a MCS. Based on the uplink buffer status of the UE 110, the proper RB (s) as well as MCS may be determined by the network device 120 and indicated to the UE 110.

In an embodiment, the network device 120 may use downlink feedback information (DFI) for the CG PUSCH e.g. CG DFI to carry the first response 360 or the second response 260.

Although the various example embodiments of the present disclosure are described in terms of the FIG. 1 to the FIG. 3, it may be appreciated that the operations and the elements in different figures can combined unless obviously contradicting each other. For example, the transmission 355 may be performed by the UE 110 after receiving the second response 260.

According to the various example embodiments of the present disclosure, the CG resource may be activated by the UE.
