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 on the MG and the PPW interaction, or the interaction between the measurement modes of an identical type. According to the example embodiments of the present disclosure, an implicit manner to simply and efficiently deactivate one measurement mode by utilizing the interaction can be accomplished.

FIG. 1 shows an exemplary sequence diagram for measurement mode interaction according to the example embodiments of the present disclosure. Referring to the FIG. 1, a UE 110 may represent any terminal device in a wireless communication network. A network device 120 may function as a base station (BS) in the wireless communication network and serving the UE 110.

Referring to the FIG. 1, in an operation 125, the network device 120 may determine, for the UE 110, configuration information 130 associated with a first measurement mode and a second measurement mode. In an example embodiment, the first and second measurement modes may be for positioning of the UE 110. The first measurement mode may comprise performing PRS measurement within MG or within PPW, and the second measurement mode may comprise performing PRS measurement within MG or within PPW.

In an example embodiment, the first measurement mode may comprise performing PRS measurement within MG, and the second measurement mode may comprise performing PRS measurement within PPW. Alternatively, in an example embodiment, the first measurement mode may comprise performing PRS measurement within PPW, and the second measurement mode may comprise performing PRS measurement within MG. Alternatively, in an example embodiment, the first measurement mode may comprise performing PRS measurement within MG of a version, and the second measurement mode may comprise performing PRS measurement within MG of another version. Alternatively, in an example embodiment, the first measurement mode may comprise performing PRS measurement within PPW of a version, and the second measurement mode may comprise performing PRS measurement within PPW of another version. Then, the network device 120 may transmit, to the UE 110, the configuration information 130.

The configuration information 130 may be carried in, for example, a radio resource control (RRC) signaling.

Receiving the configuration information 130, in an operation 140, the UE 110 may determine, based on the configuration information 130, whether the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110. Alternatively, as an option, the UE 110 may determine whether the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110 without reference to the configuration information 130. For example, the UE 110 may make such determination regardless of whether receiving the configuration information 130.

In an embodiment, the UE 110 may transmit a message 122 relating to capability of the UE 110 to the network device 120. The message 122 may also be referred as to a UE capability message. In this case, receiving the message 122 from the UE 110, in the operation 125, the network device 120 may determine the configuration information 130 based on the message 122.

For example, in a case where the message 122 indicates that the UE 110 is capable to perform PRS measurements both within the MG and within the PPW, the network device 120 may determine the configuration information 130 allowing the UE 110 to be configured or activated in parallel use of the first measurement mode and the second measurement mode. For example, in a case where the message 122 indicates that the UE 110 is incapable to perform PRS measurements both within the MG and within the PPW, the network device 120 may determine the configuration information 130 prohibiting the UE 110 to be configured or activated in parallel use of the first measurement mode and the second measurement mode, for example, the configuration information 130 may be determined to allow the UE 110 to use one of the first measurement mode and the second measurement mode.

In an embodiment, the configuration information 130 may comprise an indication 132 on whether the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110. For example, the indication 132 may explicitly indicate whether the first measurement mode and the second measurement mode can be configured or activated in parallel use or not. Receiving the indication 132, in the operation 145, the UE 110 may determine whether the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110 based on the indication 132. In a case where the indication 132 indicates that the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110, the UE 110 may determine that the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110. In a case where the indication 132 indicates that the first measurement mode and the second measurement mode are configured or activated without parallel use for the UE 110, the UE 110 may determine that the first measurement mode and the second measurement mode are configured or activated without parallel use for the UE 110.

Alternatively or additionally, in an embodiment, the configuration information 130 may comprise a rule 134 for the UE 110 to determine whether the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110. Receiving the rule 134, in the operation 145, the UE 110 may determine whether the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110 based on the rule 134.

The rule 134 could be associated with the capability of the UE 110. If the UE 110 has higher measurement capability, it may determine to activate both the first measurement mode and the second measurement mode in parallel. Alternatively or additionally, the rule 134 could be associated with positioning serving requirement (e.g., accuracy requirement and latency requirement) . If higher positioning requirement is needed, the UE 110 may determine to activate both the first measurement mode and the second measurement mode in parallel. Alternatively or additionally, the rule 134 could be associated with battery information of the UE 110. If the battery of the UE 110 has a higher electric quantity, the UE 110 may determine to activate both the first measurement mode and the second measurement mode in parallel.

Alternatively or additionally, in an embodiment, contents of the indication 132 or the rule 134 may be fixed in a specification.

As an option, the UE 110 may report the outcome determined in the operation 145 to the network device 120.

In an operation 135, the network device 120 may determine, for the UE 110, configuration message 140 associated with the first measurement mode and the second measurement mode, and transmit the configuration message 140 to the UE 110. Receiving the configuration message 140 from the network device 120, the UE 110 may determine, based on the configuration message 140, which of the first measurement mode and the second measurement mode to be used.

Regardless of whether the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110, the network device 120 may transmit the configuration message 140 to the UE 110.

In an embodiment, the configuration message 140 may comprise an instruction 142 on which of the first measurement mode and the second measurement mode to be used. The instruction 142 may explicitly instruct the UE 110 to conduct the measurement, e.g. the PRS measurement, within the MG, to conduct the measurement within the PPW, or to conduct the measurement both within the MG and within the PPW.

Receiving the instruction 142, in an operation 175, the UE 110 may conduct the measurement using at least one of the first measurement mode and the second measurement mode instructed in the instruction 142.

Alternatively or additionally, the UE 110 may determine which of the first measurement mode and the second measurement mode to be used based on whether a condition 155 is met. For example, in a case where for the UE 110 the first measurement mode and the second measurement mode are configured or activated in parallel use for the UE 110 ( “Yes” prong of the operation 145) , in an operation 170, the UE 110 may determine the first measurement mode, the second measurement mode, or both to be used. For example, in a case where for the UE 110 the first measurement mode and the second measurement mode are configured or activated without parallel use for the UE 110 ( “No” prong of the operation 145) , in an operation 160, the UE 110 may determine one of the first measurement mode and the second measurement mode to be used.

In an embodiment, the condition 155 may be associated with cases such as the MG and the PPW are non-overlapping, partially overlapping, or fully overlapping in time and frequency resources. For example, in the

operation

160 or 170, the UE 110 may determine which of the first measurement mode and the second measurement mode to be used based on the instruction 142 when the MG and the PPW are partially overlapping, or fully overlapping in time and frequency resources. Optionally the UE 110 may not follow the instruction 142 when the MG and the PPW are non-overlapping in time and frequency resources.

Alternatively or additionally, in an embodiment, the condition 155 may comprise a first threshold number of transmission and reception points (TRPs) , from which the UE 110 is able to measure PRSs. For example, if the UE 110 can measure the PRSs from the TRPs whose number is more than the first threshold number, in the

operation

160 or 170, the UE 110 may determine the first measurement mode or the second measurement mode to be used despite the instruction 142. For example, if the UE 110 can measure the PRSs within the PPW from more than the first threshold number TRPs, in the

operation

160 or 170, the UE 110 may determine to perform the measurement within the PPW, and the measurement within the MG may be not needed, or vice versa. The TRP may be associated with one or more BSs.

Alternatively or additionally, in an embodiment, the condition 155 may comprise a second threshold number of PRSs the UE 110 is able to measure. For example, if the UE 110 can measure the PRSs whose number is more than the second threshold number, in the

operation

160 or 170, the UE 110 may determine the first measurement mode or the second measurement mode to be used despite the instruction 155. For example, if the UE 110 can measure more than the second threshold number PRSs within the PPW, in the

operation

160 or 170, the UE 110 may determine to perform the measurement within the PPW, and the measurement within the MG may be not needed, or vice versa.

In the above embodiments, for example, in a case where the reference signal receiving power (RSRP) or the reference signal receiving quality (RSRQ) of the PRS received at the UE 110 is above a certain criteria, the UE 110 is able to measure the PRS.

Alternatively or additionally, in an embodiment, the condition 155 may comprise a third threshold of power level. For example, when the power level of the UE 110 drops below the third threshold, in the

operation

160 or 170, the UE 110 may determine the first measurement mode or the second measurement mode to be used despite the instruction 142.

The condition 155 may be fixed in a specification or preconfigured at the UE 110 beforehand. Alternatively, the network device 120 may in an operation 150 set the condition 155 for the UE 110 to determine which of the first measurement mode and the second measurement mode to be used, and then transmit the condition 155 to the UE 110.

In a case where the UE 110 in the

operation

160 or 170 determines which of the first measurement mode and the second measurement mode to be used based on whether the condition 155 is met, in the operation 175, the UE 110 may conduct measurement using the determined at least one of the first measurement mode and the second measurement mode.

In a case where for the UE 110 the first measurement mode and the second measurement mode are configured or activated without parallel use for the UE 110 ( “No” prong of the operation 140) , one of the first measurement mode and the second measurement mode may be deactivated in an implicit manner. For example, in a case where one of the first measurement mode and the second measurement mode is currently used and inappropriate, in the operation 160, the UE 110 may determine to switch to the other measurement mode, in the following operations the UE 110 may implicitly deactivate the current measurement mode and request to switch to the other measurement mode. Assuming that the second measurement mode is currently used and inappropriate, for example, the RSRP or the RSRQ of the PRS received under the second measurement mode is worse than a threshold value, or the UE is not able to provide required quality of service (QoS) of positioning measurement in the second measurement mode, or the electric quantity of the battery is lower and the measurement performed under the first measurement mode is more power saving, in the operation 160, the UE 110 may determine to switch to the first measurement mode. Alternatively or additionally, if the measurement mode determined in the operation 160, e.g., based on the configuration message 140 or the condition 155 is inappropriate, in the operation 160, the UE 110 may further determine to switch to the other measurement mode.

Assuming that the UE 110 is to deactivate the second measurement mode, the UE 110 may transmit, to the network device 120, a request 180 for the first measurement mode. On the side of the network device 120, the request 180 for the first measurement mode may be deemed as an implicit request for deactivating the second measurement mode. Receiving the request 180, in an operation 185, the network device 120 may deactivate the second measurement mode for the UE 110 based on the request 180. The network device 120 may transmit, to the UE 110, a signaling 190 for the first measurement mode. The signaling 190 may assign or configure the MG or the PPW to the UE 110, or the signaling 190 may be an activation command for the MG or the PPW to the UE 110. On the side of the UE 110, the signaling 190 for the first measurement mode may be deemed as an implicit signaling for deactivating the second measurement mode. Receiving the signaling 190, the UE 110 may deactivate the second measurement mode based on the signaling 190. Thus, there is no need to introduce new signaling such as a RRC signaling or a medium access control-control element (MAC-CE) signaling for deactivating the measurement mode, and the MG or the PPW may be simply and efficiently deactivated.
