Patent Description:
A New Radio (NR) system supports a multi-beam operation. In order to achieve a full coverage for paging, the NR system supports paging for beam sweeping, and each beam carries a same paging message.

For the sake of power-saving, a User Equipment (UE) needs to monitor a power-saving signal before monitoring the paging. When the UE determines, through monitoring the power-saving signal, that there is the paging message to be transmitted, it continues to monitor the paging message or a Physical Downlink Control Channel (PDCCH) signal corresponding to the paging message. Otherwise, the UE does not monitor the corresponding paging message or the PDCCH signal corresponding to the paging signal, and instead, it continues to monitor the power-saving signal on a next occasion. The power-saving signal has a lower parsing complexity level or a smaller quantity of parsing times than the PDCCH signal, so it is able to achieve a power-saving effect. However, in the NR system in the related art, when a beam sweeping mode is adopted, it is impossible to determine a time-domain position of the power-saving signal, so it is impossible to achieve the power-saving effect.

<CIT> & <CIT> relates to a base station, user equipment, and methods therein related to physical wake-up signaling.

<CIT> relates to a method and apparatus for detecting indication information, and a method and device for relay transmission.

The present invention provides a signal processing method and a signal processing apparatus as defined in the annexed claims, so as to solve the problem that it is impossible to determine the time-domain position of the power-saving signal and thereby it is impossible to achieve the power-saving effect.

The present disclosure has the following beneficial effect:
according to the signal processing method in the embodiments of the present disclosure, the time-domain position of the power-saving signal is determined at first, so it is able to effectively monitor the power-saving signal at the time-domain position, thereby to achieve a power-saving effect.

In order to make the objects, the technical solutions and the advantages of the present disclosure more apparent, the present disclosure will be described hereinafter in details in conjunction with the drawings and embodiments. The present invention is defined by the attached independent claims. Advantageous embodiments are described in the attached dependent claims.

As shown in <FIG>, the present disclosure provides a signal processing method, according to the claimed invention, and which includes:.

Here, through Steps <NUM> and <NUM>, a UE to which the signal processing method in the embodiments of the present disclosure is applied determines the time-domain position for monitoring the power-saving signal at first, so it is able to effectively monitor the power-saving signal at the time-domain position, thereby to achieve a power-saving effect.

The power-saving signal is a Channel State Information Reference Signal (CSI-RS) of the channel, a wake-up signal, a synchronization signal, or a special Physical Downlink Control Channel (PDCCH), which will not be particularly defined herein.

In a possible embodiment of the present disclosure, as shown in <FIG>, Step <NUM> includes:.

Through Steps <NUM> to <NUM>, the UE obtains the radio frame corresponding to the power-saving signal, then obtains the index number corresponding to the power-saving signal monitoring occasion, and finally obtains the time-domain position of the power-saving signal corresponding to the index number, so as to facilitate the subsequent monitoring of the power-saving signal.

In a possible embodiment of the present disclosure, Step <NUM> includes:.

Here, powersavingframeoffset, T, N and S-TMSI are configured by a network or predefined (defined through a protocol). The SFN corresponding to the power-saving signal is obtained through a corresponding formula in conjunction with a relationship between the power-saving signal periodicity and the paging periodicity. The relationship between the power-saving signal periodicity and the paging periodicity includes the parameter k, and k is an integer greater than <NUM>.

In addition, in the embodiments of the present disclosure, Step <NUM> includes:
taking an SFN corresponding to a paging monitoring occasion as the SFN corresponding to the power-saving signal.

Here, the SFN of a paging signal continues to be used by the radio frame corresponding to the power-saving signal.

In a possible embodiment of the present disclosure, subsequent to obtaining the radio frame corresponding to the power-saving signal, Step <NUM> includes:
obtaining an index number i_s through a formula i_s=floor (UE_ID/N) mod Ns, where Ns represents the quantity of paging occasions associated with one paging radio frame, and UE_ID= S-TMSI mod <NUM>.

Here, i_s is obtained through the formula i_s = floor (UE_ID/N) mod Ns, and i_s=<NUM>, <NUM>,. , so as to enable the UE to monitor an (i_s+<NUM>)th power-saving signal occasion with the SFN as a start point.

In a possible embodiment of the present disclosure, the time-domain position includes a start time point, and Step <NUM> includes:
determining a start time point of the power-saving signal occasion corresponding to a current index number.

The determining the start time point of the power-saving signal occasion corresponding to the current index number includes:.

Hence, on one hand, the time-domain start position of the [(i_s*x)+<NUM>]th power-saving signal is directly taken as the start time point of the power-saving signal occasion corresponding to the current index number, and on the other hand, the start time point of the power-saving signal monitoring occasion corresponding to the current index number is looked up in accordance with the start position of each configured power-saving signal occasion.

The taking the time-domain start position of the [(i_s*x)+<NUM>]th power-saving signal as the start time point of the power-saving signal occasion corresponding to the current index number includes:.

Here, for a slot-scale power-saving signal (one power-saving signal that occupies one complete slot), the position t+M is calculated as the position where the [(i_s*x)+<NUM>]th power-saving signal occurs in conjunction with t, i_s and x. For a symbol-scale power-saving signal (one power-saving signal that does not occupy one complete slot) or when two power-saving signals are not continuous (i.e., when the two power-saving signals are spaced apart from each other by one or more slots), the position of each power-saving signal in each power-saving signal occasion is determined in accordance with the duration of the power-saving signal and the periodicity and/or the periodicity offset of the power-saving signal, and then the positions of the power-saving signals are ranked to obtain the position where the [(i_s*x)+<NUM>]th power-saving signal occurs.

The parameter t is configured by the network device or indicated by a predefined power-saving signal occasion firstpowersavingoccasion.

For example, as shown in <FIG>, in a power-saving signal radio frame with SFN=<NUM>, when the current index number i_s=<NUM> and a start time point of a first power-saving signal is within a slot <NUM> (slot=<NUM>) (t=<NUM> slot), a start time point of an (i_s+<NUM>)th power-saving signal is the time-domain start position where the [(i_s*x)+<NUM>]th power-saving signal occurs.

In addition, in a possible embodiment of the present disclosure, the time-domain position further includes a position of the power-saving signal occasion,
wherein the obtaining the time-domain position of the power-saving signal corresponding to the index number includes:.

For example, as shown in <FIG>, x=<NUM>, and y=<NUM> slot. In the power-saving signal radio frame with SFN=<NUM>, a power-saving signal occasion with an index number i_s=<NUM> is slot0 to slot3 (i.e., <NUM>*<NUM>). As shown in <FIG>, x=<NUM>, the duration is provided with respect to a symbol, and y=<NUM> symbols. In the power-saving signal radio frame with SFN=<NUM>, the power-saving signal occasion with the index number i_s=<NUM> is symbol0 to symbol <NUM> in slot1.

In a possible embodiment of the present disclosure, the time-domain position further includes a symbol carrying the power-saving signal;
the obtaining the time-domain position of the power-saving signal corresponding to the index number includes:
determining the symbol carrying the power-saving signal in the position of the power-saving signal occasion corresponding to the index number in accordance with a symbol position of the power-saving signal.

Here, considering the circumstance where the symbol position of the power-saving signal has been configured, the symbol carrying the power-saving signal is determined within the power-saving signal occasion corresponding to the index number. For example, symbol positions of power-saving signals within one slot are <NUM> (where <NUM> represents a position where the power-saving signal occurs). As shown in <FIG>, x=<NUM>, and y=<NUM> symbols. Within the power-saving signal radio frame with SFN=<NUM>, the power-saving signal occasion with the index number i_s=<NUM> is symbol1 to symbol <NUM> and symbol5-symbol7 within slot1, and symbol1 to symbol3 and symbol5 to symbol7 within slot3.

It should be further appreciated that, a beam sweeping mode is adopted by an NR system. In order to monitor the signal with respect to a specific beam direction, in the embodiments of the present disclosure, prior to Step <NUM>, the signal processing method further includes:
determining a target beam direction for monitoring in accordance with a beam direction of a received System Synchronization Block (SSB) and a relationship between a beam direction of the power-saving signal and the beam direction of the system synchronization block.

The relationship between the beam direction of the power-saving signal and the beam direction of the SSB is configured by the network device or predefined. It should be noted that, one beam direction of the SSB broadcast by a system may correspond to two or more beam directions of the corresponding power-saving signal, but not limited to one beam direction of the corresponding power-saving signal. For example, a beam direction <NUM> of the SSB broadcast by the system corresponds to a beam direction <NUM> of the power-saving signal, or corresponds to {the beam direction <NUM> of the power-saving signal and a beam direction <NUM> of the power-saving signal}. In this way, based on the relationship between the beam direction of the power-saving signal and the beam direction of the SSB, the UE determines a specific one or ones of the beam directions (i.e., the target beam direction) in the power-saving signal occasion upon the receipt of the beam direction of the SSB broadcast by the system.

Subsequent to determining the target beam direction being monitored, Step <NUM> includes:
monitoring the power-saving signal corresponding to the target beam direction in the power-saving signal occasion in accordance with the position of the power-saving signal occasion in the time-domain position.

Generally speaking, the network device transmits time-domain configuration information for configuring the power-saving signal to the UE, so that the UE determines the time-domain position for monitoring the power-saving signal in accordance with the time-domain configuration information and other predefined parameters. In the embodiments, prior to Step <NUM>, the signal processing method further includes:
receiving the time-domain configuration information about the network device, wherein the time-domain configuration information is used to configure the time-domain position of the power-saving signal.

In a possible embodiment of the present disclosure, the time-domain configuration information includes at least one of:.

In this way, the UE is capable of determining the frame position of the power-saving signal in accordance with the time-domain configuration information for configuring the power-saving signal and the frame offset powersavingframeoffset; determines the start position of each power-saving signal monitoring occasion in accordance with the occurring occasion firstpowersavingoccasion (in unit of slot); determines the position where the power-saving signal occurs in accordance with the periodicity periodicitypowersaving (in unit of slot or symbol); determines the position where the power-saving signal occurs in accordance with the periodicity offset; determines the symbol corresponding to the power-saving signal within one slot or the symbol at a start position of the power-saving signal within one slot in accordance with the symbol position; determines the quantity of consecutive slots or consecutive symbols occupied by the power-saving signal in accordance with the duration; and determines that the power-saving signal periodicity is equal to number k of paging periodicities in accordance with the relationship between the power-saving signal periodicity and the paging periodicity.

The signal processing method in the embodiments of the present disclosure will be described hereinafter in conjunction with different scenarios.

First scenario: the UE monitors the power-saving signal once within each paging periodicity, UE_ID =<NUM>-S-TMSI mod <NUM> = <NUM>, T=<NUM>, N=<NUM>, Ns=<NUM>, powersavingframeoffset=<NUM>, duration=<NUM> slot, x=<NUM>.

At first, radio frames with SFN=<NUM>, <NUM>,. , <NUM>+<NUM>* l (l is a positive integer greater than or equal to <NUM>) within which the power-saving signal is monitored by the UE are determined through a formula (SFN + powersavingframeoffset) mod T = (T div N)*(UE_ID mod N), i.e., SFN mod <NUM> =(32div8)*(5mod8).

Next, i_s = floor(<NUM>/<NUM>)mod2 =<NUM> is calculated through a formula i_s = floor (UE_ID/N) mod Ns. Hence, as shown in <FIG>, a start time point of the power-saving signal monitoring occasion of by the UE is a first power-saving signal occasion with SFN=<NUM>+<NUM>* l (l is a positive integer greater than or equal to <NUM>). An (i_s+<NUM>)th power-saving signal occasion is a time length of consecutive x*durations with a position where an [(i_s*x)+<NUM>]th power-saving signal occurs (i.e., i_s*x slots) as a start point, so a first power-saving signal occasion is determined as consecutive four (i.e., <NUM>*<NUM>) slots, corresponding to slot0 to slot3 in <FIG>, with a time point where a first power-saving signal occurs (i.e., slot0) as a start point. Further, when the beam sweeping mode is adopted, the quantity x of the power-saving signals within one sweeping period correspond to the beam directions of the SSB broadcast by the system respectively. For example, a beam direction <NUM> of the SSB broadcast by the system corresponds to a beam direction <NUM> of the power-saving signal, or corresponds to {the beam direction <NUM> of the power-saving signal and a beam direction <NUM> of the power-saving signal}. Based on the correspondence, the UE determines a specific one or ones of the beams to be monitored in the power-saving signal occasion upon the receipt of the beam direction of the SSB broadcast by the system. When the UE has received the beam direction <NUM> of the SSB broadcast by the system, the UE merely needs to monitor the beam direction <NUM> of the power-saving signal, or {the beam directions <NUM> and <NUM> of the power-saving signal}, in the power-saving signal occasion. With respect to the above-mentioned specific configuration, the UE merely needs to monitor slot1, or {slot1 and slot <NUM>}, in the power-saving signal occasion.

It should be noted that, in the above content, the power-saving signal occasion (firstpowersavingoccasion) is equal to <NUM> by default. When firstpowersavingoccasion is not equal to <NUM> and an offset of firstpowersavingoccasion is <NUM> slots, as shown in <FIG>, the first power-saving signal occasion is consecutive <NUM> (i.e., <NUM>*<NUM>) slots with firstpowersavingoccasion (i.e., slot2) as a start point.

Second scenario: the UE monitors the power-saving signal once within each paging periodicity, UE_ID =<NUM>-S-TMSI mod <NUM> = <NUM>, T=<NUM>, N=<NUM>, Ns=<NUM>, powersavingframeoffset=<NUM>, duration=<NUM> symbols, and x=<NUM>. In addition, the periodicity and the periodicity offset of the power-saving signal are configured by the network device or predefined, periodicity=<NUM> slots, and periodicity offset=<NUM> slot.

Radio frames with SFN=<NUM>, <NUM>,. , <NUM>+<NUM>* l (l is a positive integer greater than or equal to <NUM>) within which the power-saving signal is monitored by the UE are determined through a formula (SFN + powersavingframeoffset) mod T = (T div N)*(UE_ID mod N), i.e., SFN mod <NUM> =(32div8)*(5mod8).

Next, i_s = floor(<NUM>/<NUM>)mod2 =<NUM> is calculated through a formula i_s = floor (UE_ID/N) mod Ns. An (i_s+<NUM>)th power-saving signal occasion is a time length of consecutive x*durations with a start position of an (i_s*x+<NUM>)th power-saving signal as a start point. The start position of the (i_s*x+<NUM>)th power-saving signal is determined in accordance with a duration of the power-saving signal, and a periodicity of the power-saving signal and/or a periodicity offset of the power-saving signal, to determine a position of each power-saving signal in each power-saving signal occasion. Then, the positions of the power-saving signals are ranked to obtain the time-domain start position of the [(i_s*x)+<NUM>]th power-saving signal. Hence, as shown in <FIG>, a start time point of the power-saving signal monitoring occasion of the UE is a first power-saving signal occasion with SFN=<NUM>+<NUM>* l (l is a positive integer greater than or equal to <NUM>). The first power-saving signal occasion is consecutive <NUM> (i.e., <NUM>*<NUM>) symbols with a first symbol in slot=<NUM> as a start point, i.e., the power-saving signal monitoring occasion with the index number i_s=<NUM> is symbol0 to symbol11 in slot1. Identically, when the beam sweeping mode is adopted, the quantity x of the power-saving signals within one sweeping period correspond to the beam directions of the SSB broadcast by the system respectively. For example, a beam direction <NUM> of the SSB broadcast by the system corresponds to a beam direction <NUM> of the power-saving signal, or corresponds to {the beam direction <NUM> and a beam direction <NUM> of the power-saving signal}. Based on the correspondence, the UE determines a specific one or ones of the beams to be monitored in the power-saving signal occasion upon the receipt of the beam direction of the SSB broadcast by the system. When the UE has received the beam direction <NUM> of the SSB broadcast by the system, the UE merely needs to monitor the beam direction <NUM> of the power-saving signal (i.e., symbol0 to symbol2 in slotl), or {the beam directions <NUM> and <NUM> of the power-saving signal} (i.e., symbol0 to symbol2 and symbol6 to symbol8 in slotl), in the power-saving signal occasion.

Third scenario: the UE monitors the power-saving signal once within each paging periodicity, UE_ID =<NUM>-S-TMSI mod <NUM> = <NUM>, T=<NUM>, N=<NUM>, Ns=<NUM>, powersavingframeoffset=<NUM>, duration=<NUM> symbols, and x=<NUM>. In addition, the periodicity and the periodicity offset of the power-saving signal and the position of the symbol (powersavingsymbolsinslot) are configured by the network device or predefined, periodicity=<NUM> slots, periodicity offset=<NUM> slot, and powersavingsymbolsinslot=<NUM> (<NUM> represents a position where the power-saving signal occurs).

In this way, radio frames with SFN=<NUM>, <NUM>,. , <NUM>+<NUM>* l (l is a positive integer greater than or equal to <NUM>) within which the power-saving signal is monitored by the UE are determined through a formula (SFN + powersavingframeoffset) mod T = (T div N)*(UE_ID mod N), i.e., SFN mod <NUM> =(32div8)*(5mod8).

Next, i_s = floor(<NUM>/<NUM>)mod2 =<NUM> is calculated through a formula i_s = floor (UE_ID/N) mod Ns. An (i_s+<NUM>)th power-saving signal occasion is a time-domain length of number x of power-saving signals after a start position of the (i_s*x+<NUM>)th power-saving signal as a start point. A position of each power-saving signal in each power-saving signal occasion is determined in accordance with a duration of the power-saving signal, and a periodicity of the power-saving signal and/or a periodicity offset of the power-saving signal. Then, the positions of the power-saving signals are ranked to obtain the time-domain start position of the [(i_s*x)+<NUM>]th power-saving signal. In addition, the UE determines a symbol carrying the power-saving signal at a time-domain position of the power-saving signal occasion corresponding to the index number in accordance with the symbol position of the power-saving signal. Hence, as shown in <FIG>, a start time point of the power-saving signal monitoring occasion of the UE is a first power-saving signal occasion with SFN=<NUM>+<NUM>* l (l is a positive integer greater than or equal to <NUM>). The first power-saving signal occasion is symbol positions of the power-saving signals within slot=<NUM> and slot=<NUM>, i.e., symbol1 to symbol3 and symbol5 to symbol7 within slot1 and symbol1 to symbol3 and symbol5 to symbol7 in slot3. Identically, when the beam sweeping mode is adopted, the quantity x of the power-saving signals within one sweeping period correspond to the beam directions of the SSB broadcast by the system respectively. For example, a beam direction <NUM> of the SSB broadcast by the system corresponds to a beam direction <NUM> of the power-saving signal, or corresponds to {the beam direction <NUM> and a beam direction <NUM> of the power-saving signal}. Based on the correspondence, the UE determines a specific one or ones of the beams to be monitored in the power-saving signal occasion upon the receipt of the beam direction of the SSB broadcast by the system. When the UE has received the beam direction <NUM> of the SSB broadcast by the system, the UE merely needs to monitor the beam direction <NUM> of the power-saving signal (i.e., symbol1 to symbol3 in slotl), or {the beam directions <NUM> and <NUM> of the power-saving signal} (i.e., symbol1 to symbol3 in slot1 and symbol1 to symbol3 in slot3), in the power-saving signal occasion.

Fourth Scenario: the UE monitors the power-saving signal once within each paging periodicity, UE_ID =<NUM>-S-TMSI mod <NUM> = <NUM>, T=<NUM>, N=<NUM>, Ns=<NUM>, powersavingframeoffset=<NUM>, duration=<NUM> symbols, x=<NUM>, periodicity=<NUM> slots, periodicity offset=<NUM> slot, and powersavingsymbolsinslot=<NUM> (<NUM> represents a position of the power-saving signal). As shown in <FIG>, a start time point of a first power-saving signal occasion within one paging radio frame is slot=<NUM>, and a start time point of a second power-saving signal occasion is slot=<NUM>.

Next, i_s = floor(<NUM>/<NUM>)mod2 =<NUM> is calculated through a formula i_s = floor (UE_ID/N) mod Ns. Hence, as shown in <FIG>, a start time point of the power-saving signal monitoring occasion of the UE is a second power-saving signal occasion (i_s=<NUM>) with SFN=<NUM>+<NUM>* l (l is a positive integer greater than or equal to <NUM>), and the second power-saving signal occasion is symbol positions of the power-saving signals within slot=<NUM> and slot=<NUM>. Identically, when the beam sweeping mode is adopted, the quantity x of the power-saving signals within one sweeping period correspond to the beam directions of the SSB broadcast by the system respectively. For example, a beam direction <NUM> of the SSB broadcast by the system corresponds to a beam direction <NUM> of the power-saving signal, or corresponds to {the beam direction <NUM> and a beam direction <NUM> of the power-saving signal}. Based on the correspondence, the UE determines a specific one or ones of the beams to be monitored in the power-saving signal occasion upon the receipt of the beam direction of the SSB broadcast by the system. When the UE has received the beam direction <NUM> of the SSB broadcast by the system, the UE merely needs to monitor the beam direction <NUM> of the power-saving signal, or {the beam directions <NUM> and <NUM> of the power-saving signal}, in the power-saving signal occasion.

It should be appreciated that, in the embodiments of the present disclosure, when the power-saving signal periodicity configured by the network device or predefined is equal to number k of paging periodicities and the UE has monitored one power-saving signal in accordance with the configuration, it means that the UE needs to monitor number k of subsequent paging until a paging message has been monitored. When no power-saving signal has been monitored in accordance with the configuration, it means that the UE does not need to monitor the k subsequent paging. In other words, the periodicity with which the UE monitors the power-saving signal is k times of the monitoring of the paging periodicity. Hence, a condition for the UE to determine the radio frame for monitoring the power-saving signal is changed to (SFN + powersavingframeoffset) mod (k*T) = (T div N)*(UE_ID mod N). The UE determines the index number i_s corresponding to the power-saving signal monitoring occasion and the time-domain position occupied by the (i_s+<NUM>)th power-saving signal occasion in the above-mentioned modes, which will not be particularly defined herein.

In a word, according to the signal processing method in the embodiments of the present disclosure, the time-domain position for monitoring the power-saving signal is determined at first, so it is able to effectively monitor the power-saving signal at the time-domain position, thereby to achieve a power-saving effect.

As shown in <FIG>, the present disclosure further provides a signal processing method, which is not according to the claimed invention, and which includes:
Step <NUM> of transmitting time-domain configuration information, wherein the time-domain configuration information is used to configure a time-domain position of the power-saving signal.

The computer-readable storage medium includes, but not limited to, a Random Access Memory (e.g., Phase Change Random Access Memory (PRAM), Static Random Access Memory (SRAM) or Dynamic Random Access Memory (DRAM)), a Read Only Memory (ROM) (e.g., an Electrically Erasable Programmable Read Only Memory (EEPROM), a flash memory, a Compact Disc Read Only Memory (CD-ROM) or a Digital Video Disk (DVD)), a magnetic storage device (e.g., a cassette magnetic tape or a magnetic disk), or any other non-transmission medium capable of storing therein information which can be accessed by a computing device. As defined in the embodiments of the present disclosure, the computer-readable storage medium does not include any transitory media, e.g., modulated data signal or carrier.

It should be further appreciated that, the UE described in the specification includes, but not limited to, smart phone or tablet computer. The functional members described in the specification are referred to as modules, so as to emphasize the independence of the implementation in a more particular manner.

In the embodiments of the present disclosure, the modules may be implemented by software, so as to be executed by various processors. For example, an identified, executable code module includes one or more physical or logical blocks including computer instructions, and the module is constructed as an object, a process or a function. Even so, the executable codes of the identified modules are unnecessary to be physically located together, but include different instructions stored in different locations. When these instructions are logically combined together, they form the modules and achieve the prescribed purposes of the modules.

Actually, the executable code module is a single instruction or a plurality of instructions, and even it is distributed at different code segments, in different programs, or across a plurality of memory devices. Also, operational data is identified in the modules, implemented in any appropriate form, and organized in any data structure of an appropriate type. The operational data is collected as a single data set, or distributed at different locations (including different memory devices), and it is at least partially present in a system or network merely as an electronic signal.

When the modules can be implemented by software, considering the hardware level in the related art, a person skilled in the art can build a corresponding hardware circuit to achieve the corresponding function if taking no account of the cost. The hardware circuit includes a conventional very-large-scale integration (VLSI) circuit, a gate array, a semiconductor such as a logic chip and a transistor, or other discrete components in the related art. The modules are further implemented by a programmable hardware device, such as a field-programmable gate array, a programmable array logic device and a programmable logic device.
