SCHEDULING CELL SIGNAL MEASUREMENTS IN WIRELESS COMMUNICATION SYSTEMSTECHNICAL FIELD
[0001] This disclosure is directed generally to digital wireless communications.BACKGROUND
[0002] Mobile telecommunication technologies are moving the world toward an increasingly connected and networked society. In comparison with the existing wireless networks, next generation systems and wireless communication techniques will need to support a much wider range of use-case characteristics and provide a more complex and sophisticated range of access requirements and flexibilities.
[0003] Long-Term Evolution (LTE) is a standard for wireless communication for mobile devices and data terminals developed by 3rd Generation Partnership Project (3GPP) . LTE Advanced (LTE-A) is a wireless communication standard that enhances the LTE standard. The 5th generation of wireless system, known as 5G, advances the LTE and LTE-A wireless standards and is committed to supporting higher data-rates, large number of connections, ultra-low latency, high reliability and other emerging business needs.SUMMARY
[0004] In 5G advanced and 6G communication systems, multimodal services are becoming ubiquitous. However, multimodal services require low-latency communications, and when packets are scheduled to be transmitted during cell signal measurement durations, a significant scheduling delay may be incurred. Embodiments of the disclosed technology provide methods and systems for dynamically relaxing the scheduling requirement in time periods that are dedicated for cell signal measurements. In an example, this is achieved by classifying symbols as different types and / or using a finer granularity when scheduling.
[0005] In an example aspect, a wireless communication method includes determining, by a wireless device based on a condition, a time duration for performing a measurement. In this example, the time duration includes one or more first time intervals associated with at least one first symbol and one or more second time intervals associated with at least one second symbol. The method further includes the wireless device receiving, from a network node, a transmission during the one or more second time intervals, and performing, during the one or more first time intervals, the measurement. Herein, the wireless device is configured to refrain from receiving, during the one or more first time intervals, the transmission.
[0006] In another example aspect, a wireless communication method includes determining, by a wireless device based on a condition, a time duration for performing a measurement. In this example, the time duration includes one or more first time intervals associated with at least one first symbol and one or more second time intervals associated with at least one second symbol. The method further includes the wireless device transmitting, to a network node, a transmission during the one or more second time intervals. Herein, the wireless device is configured to refrain from transmitting, during the one or more first time intervals, the transmission.
[0007] In yet another example aspect, the above-described methods are embodied in the form of processor-executable code and stored in a non-transitory computer-readable storage medium. The code included in the computer readable storage medium when executed by a processor, causes the processor to implement the methods described in this patent document.
[0008] In yet another example embodiment, a device that is configured or operable to perform the above-described methods is disclosed.
[0009] The above and other aspects and their implementations are described in greater detail in the drawings, the descriptions, and the claims.

[0024] In existing wireless communication systems (e.g., Fifth Generation (5G) and New Radio (NR) ) , a wireless device is configured to measure a signal strength of the serving cell periodically, and evaluate the cell selection criterion based thereon. In an example, the signal strength measure includes the RSRP (Reference Signal Received Power) in decibel-milliwatts (dBm) and / or the RSRQ (Reference Signal Received Quality) in decibels (dB) .
[0025] FIG. 1 shows an example of the measurement gap length, which includes the actual measurement window and the RF retuning time on each end of the measurement gap. A measurement gap may be supported for different frequency ranges for the identification and measurement of intra-frequency cells and / or inter-frequency cells and / or inter-RAT E-UTRAN cells. The actual measurement window includes, as shown in FIG. 1, a synchronization signaling / physical broadcast channel block (SSB) -based measurement timing configuration (SMTC) window. The measurement gap may be defined per-FR (frequency range) or per-UE.
[0026] The current specification (e.g., ETSI TS 138 133 V16.4.0) specifies that during the per-UE measurement gap, the UE is not required to conduct reception / transmission from / to the corresponding E-UTRAN PCell, E-UTRAN Scell (s) and NR serving cells for E-UTRA-NR dual connectivity except the reception of signals used for RRM measurement (s) and the signals used for random access procedures. However, this restriction can lead to increased latency, which can be significantly problematic for multimodal services that require low-latency communications.
[0027] Embodiments of the disclosed technology provide methods and systems for relaxing the scheduling requirement in the measurement gaps, which advantageously decreases the latency experienced. The example headings for the various sections below are used to facilitate the understanding of the disclosed subject matter and do not limit the scope of the claimed subject matter in any way. Accordingly, one or more features of one example section can be combined with one or more features of another example section. Furthermore, 5G terminology is used for the sake of clarity of explanation, but the techniques disclosed in the present document are not limited to 5G technology only, and may be used in wireless systems that implemented other protocols.

[0064] 1.3 Determining the first symbols and second symbols
[0065] In some embodiments, determining at least one first symbol and / or at least one second symbol in the time duration is based on scheduling determination information.
[0066] In some embodiments, the scheduling determination information includes a bitmap for one time duration, with each bit of the bitmap corresponding to a symbol within the time duration.
[0067] In some embodiments, each bit within the bitmap has a one-to-one mapping to a symbol in an ascending order of the symbol index in the time duration. Here, a ‘1’ -valued bit indicates the symbol is the second symbol and a ‘0’ -valued bit indicates the symbol is the first symbol. Alternatively, a ‘0’ -valued bit indicates the symbol is the second symbol and a ‘1’ -valued bit indicates the symbol is the first symbol. Alternatively, a ‘1’ -valued bit indicates the first symbol is changed to the second symbol and a ‘0’ -valued bit indicates the symbol remains the first symbol. Alternatively, a ‘0’ -valued bit indicates the first symbol is changed to the second symbol and a ‘1’ -valued bit indicates the symbol remains the first symbol. An example of a bitmap indication in an SMTC window is shown in FIG. 2.
[0068] In some embodiments, each bit of the bitmap corresponds to a symbol within one or more predefined symbol groups in the time duration. In some examples, the predefined symbols groups are determined by a higher layer parameter, e.g., associated with a SSB configuration or a CSI-RS configuration. In other examples, the higher layer parameter includes ‘SSB-MTC’ RRC signaling.
[0069] In some embodiments, each bit within the bitmap has a one-to-one mapping to a symbol in an ascending order of symbol index in a predefined symbol group in the time duration. Here, a ‘1’ -valued bit indicates the symbol is the second symbol and a ‘0’ -valued bit indicates the symbol is the first symbol. Alternatively, a ‘0’ -valued bit indicates the symbol is the second symbol and a ‘1’ -valued bit indicates the symbol is the first symbol. Alternatively, a ‘1’ -valued bit indicates the first symbol is changed to the second symbol and a ‘0’ -valued bit indicates the symbol remains the first symbol. Alternatively, a ‘0’ -valued bit indicates the first symbol is changed to the second symbol and a ‘1’ -valued bit indicates the symbol remains the first symbol.
[0070] FIG. 3A shows an example of a predefined symbol group consisting of SSB symbols with different SSB indexes. As shown therein, four SSBs are in the SMTC window, and there are four symbols in one SSB transmission. This results in four symbol groups with each of them comprising four symbols. Here, the bitmap has a length of 16 bits, and each bit in the bitmap has a one-to-one mapping to a symbol in an ascending order of symbol index.
[0071] In some embodiments, each bit within the bitmap has a one-to-one mapping to a predefined group in ascending order of the starting symbol index of the predefined group. Here, a ‘1’ -valued bit indicates the symbols in the corresponding predefined group are second symbols and a ‘0’ -valued bit indicates the symbols in the corresponding predefined group are first symbols. Alternatively, a ‘0’ -valued bit indicates the symbols in the corresponding predefined group are second symbols and a ‘1’ -valued bit indicates the symbols in the corresponding predefined group are first symbols. Alternatively, a ‘1’ -valued bit indicates the first symbols in the corresponding predefined group are changed to second symbols and a ‘0’ -valued bit indicates the symbols in the corresponding predefined group remain the first symbols. Alternatively, a ‘0’ -valued bit indicates the first symbols in the corresponding predefined group are changed to second symbols and a ‘1’ -valued bit indicates the symbols in the corresponding predefined group remain the first symbols.
[0072] FIG. 3B shows an example of a predefined symbol group consisting of SSB symbols with different SSB indexes and 1 symbol before / after the SSB symbols. As shown therein, four SSBs are in the SMTC window, and there are four symbols in one SSB transmission. This results in four symbol groups with each of them comprising six symbols. Here, the bitmap has a length of 4 bits, and each bit in the bitmap has one-to-one mapping to the predefined symbol group in an ascending order of starting symbol index.
[0073] In some embodiments, each bit of the bitmap corresponds to a predefined period in the time duration. In some examples, the predefined period includes one or more second time intervals. In other examples, the predefined period includes one or more first time intervals. In yet other examples, the predefined period is determined by a higher layer parameter. In yet other examples, the higher layer parameter is associated with a length, a starting symbol, and / or an ending symbol of the first time interval. In yet other examples, the higher layer parameter is associated with a length, a starting symbol, and / or an ending symbol of the second time interval.
[0074] In some embodiments, each bit within the bitmap has a one-to-one mapping to a symbol in a predefined period. For example, the one-to-one mapping is between each bit and a predefined period in ascending order of the starting symbol index of the predefined period. Here, a ‘1’ -valued bit indicates the symbols in the corresponding predefined period are second symbols and a ‘0’ -valued bit indicates the symbols in the corresponding predefined period are first symbols. Alternatively, a ‘0’ -valued bit indicates the symbols in the corresponding predefined period are second symbols and a ‘1’ -valued bit indicates the symbols in the corresponding predefined period are first symbols. Alternatively, a ‘1’ -valued bit indicates the first symbols in the corresponding predefined period are changed to second symbols and a ‘0’ -valued bit indicates the symbols in the corresponding predefined period remain the first symbols. Alternatively, a ‘0’ -valued bit indicates the first symbols in the corresponding predefined period are changed to second symbols and a ‘1’ -valued bit indicates the symbols in the corresponding predefined period remain the first symbols.
[0075] FIG. 3C shows an example of a predefined symbol period consisting of SSB symbols with different SSB indexes, and 1 symbol before / after the SSB symbols. As shown therein, there are four SSBs in the SMTC window, and there are four symbols in one SSB transmission. This results in four symbol periods with each of them comprising six symbols. Here, the bitmap has a length of 4 bits, and each bit within bitmap has one-to-one mapping to the predefined symbol period in an ascending order of starting symbol index.
[0076] In some embodiments, each bit of the bitmap corresponds to a time duration, and has a one-to-one mapping to the time duration. In some examples, the mapping is in ascending order of the starting symbol index of the time duration. In other examples, the mapping is in ascending order of the starting slot index of the time duration. Here, a ‘1’ -valued bit indicates the symbols in the corresponding time duration are second symbols and a ‘0’ -valued bit indicates the symbols in the corresponding time duration are first symbols. Alternatively, a ‘0’ -valued bit indicates the symbols in the corresponding time duration are second symbols and a ‘1’ -valued bit indicates the symbols in the corresponding time duration are first symbols. Alternatively, a ‘1’ -valued bit indicates the first symbols in the corresponding time duration are changed to second symbols and a ‘0’ -valued bit indicates the symbols in the corresponding time duration remain the first symbols. Alternatively, a ‘0’ -valued bit indicates the first symbols in the corresponding time duration are changed to second symbols and a ‘1’ -valued bit indicates the symbols in the corresponding time duration remain the first symbols.
[0077] FIG. 3D shows an example of a bitmap indicating three measurement gaps, with the length of the bitmap being three. In this example, the bitmap may be interpreted as a plurality of enable / disable flags for the one or more time durations, e.g., measurement gaps. Additionally or alternatively, one bit is used for indicating the priority of the measurement. Here, a ‘1’ -valued bit in the enable / disable flag indicates the symbols in the corresponding measurement gap being second symbols and a ‘0’ -valued bit indicates the symbols in the corresponding measurement gap time duration are not subject to any change in the scheduling restrictions in the measurement. Herein, no change in the scheduling restrictions for a symbol is interpreted as the symbol being a first symbol. Alternatively, a ‘0’ -valued bit in the enable / disable flag for the measurement corresponds to no meaning and / or no application of the scheduling determination information.
[0078] In some embodiments, each bit within the bitmap has a one-to-one mapping to a symbol in one or more predefined symbol groups, e.g., all symbols within the predefined symbol groups. In other embodiments, each bit within the bitmap has a one-to-one mapping to a symbol in one or more predefined periods, e.g., all symbols within the predefined periods.
[0079] In some embodiments, each bit within the bitmap has a one-to-one mapping to a plurality of time durations. In some examples, the number of time durations that are indicated by a single bit is determined by a higher layer parameter.
[0080] In some embodiment, the bitmap indication is applied when the time duration includes an SMTC window, or an NCSG.
[0081] In some embodiments, the scheduling determination information includes a length information of the one or more first time intervals. In some examples, the length is specified in a number of symbols. Alternatively, the length may be specified based on a type of sequence that includes a number of symbols, and each set of symbols corresponds to a length of the first time interval. In other embodiments, the length of a first time interval is specified in milliseconds or seconds.

Alternatively, the offset (s) are specified using a type of sequence that includes multiple quantities of symbols, with each quantity of symbols corresponds to an offset information for a second time interval. In other examples, the offset is specified in milliseconds. Alternatively, the offset (s) are specified using a type of sequence that includes multiple millisecond values, with each millisecond value corresponding to an offset information for a second time interval.
[0088] In some embodiments, a length of the first time interval and an offset of the first time interval determine the first time interval. In other embodiments, a starting symbol of the first time interval and the length of the first time interval determine the first time interval. Similarly, the length of the second time interval and the offset of the second time interval determine the second time interval, and the starting symbol of the second time interval and the length of the second time interval determine the second time interval.

In yet other examples, a resource of the DCI signaling is associated with the time duration. In yet other examples, the resource of the DCI signaling is the control resource set. In yet other examples, the time location of control resource set is determined by physical downlink control channel search space set.
[0111] In some embodiments, the Layer 1 parameter is a dedicated group common DCI signaling. In some examples, the group common DCI signaling includes one or more information blocks, with each block corresponding to a UE. In other examples, the starting position of the information blocks is determined based on a higher layer parameter. In yet other examples, a search space set with a dedicated identifier is used for the dedicated DCI format. In yet other examples, a type of search space set for the dedicated DCI format includes at least one of a Type-2 PDCCH common search space (CSS) set, a Type2A-PDCCH CSS set, a Type3 PDCCH CSS set, or a UE-specific search space (USS) set.
[0112] In some embodiments, a dedicated field is used to indicate the scheduling determination information. In some examples, a dedicated field is behind the field of ‘PUCCH Cell indicator’ in the DCI signaling. In other examples, a dedicated field is behind the field of ‘PDCCH monitoring adaptation indication’ .
[0113] In some embodiments, scheduling determination information is determined based on a condition is that same for the first symbols and the second symbols.
[0114] In some embodiments, the first symbols and the second symbols are determined based on a condition that the UE transmits Uplink Control Information (UCI) signaling. In some examples, the UCI signaling includes a dedicated UCI signaling. In other examples, the UCI signaling is a scheduling request.
[0115] In some embodiments, the first symbols and the second symbols are determined based on a condition that the UE receives the Layer 2 signaling. In some examples, the Layer 2 signaling includes Layer 2 medium access control (MAC) control element (CE) signaling. In some examples, the Layer 2 signaling includes:
[0116] –buffer status reporting (BSR)
[0117] –delay status reporting (DSR)
[0118] –configured grant (CG) confirmation
[0119] –semi-persistent (SP) CSI-RS / CSI-IM resource set activation and / or deactivation
[0120] –SP CSI reporting on PUCCH activation / deactivation
[0121] In some embodiments, the first symbols and the second symbols are determined based on a condition that a timer expires or starts. In some examples, the timer is at least one of a Connected Mode Discontinuous Reception (CDRX) on-duration timer, a CDRX inactive timer, and / or a re-transmission timer. In other examples, the UE monitors a PDCCH when the timer starts. Alternatively, the UE monitors a PDCCH when the timer ends. Herein, the PDCCH includes the DCI signaling carrying the scheduling determination information.
[0122] In some embodiments, the condition comprises a metric associated with the measurement being greater than a threshold. In some examples, the metric includes at least one of a synchronization signaling (SS) RSRP, a CSI-RSRP, an SS-RSRQ, an SS-SINR, a CSI-SINR, a cross-link interference received signal strength indicator (RSSI) , a Layer 1 RSRP, and / or a Layer 1 SINR. In other examples, the metric is determined based on the serving cell. In yet other examples, the threshold is the metric in the neighbor cell. Alternatively or additionally, the threshold is determined by a higher layer parameter.
[0123] In some embodiments, the scheduling determination information is applied when a metric associated with the measurement is greater than the threshold. Similarly, the scheduling determination information is not applied when a metric associated with the measurement is lower than the threshold. In some examples, the UE monitors a PDCCH when a metric associated with the measurement is larger than the threshold, but does not monitor the PDCCH when the metric associated with the measurement is lower than the threshold. Herein, the PDCCH includes the DCI signaling carrying the scheduling determination information.
