Abstract
Description
TECHNICAL FIELD
[0001] The present disclosure relates generally to wireless communications, and more particularly, to methods, apparatuses and systems for cell discontinuous transmission and reception signal processing. BACKGROUND
[0002] Discontinuous transmission (DTX) and discontinuous reception (DRX) are techniques that allow user equipment and / or network to power down a large portion of its internal circuitry in the time when no signal / channel is transmitted or received. The time period when user equipment and / or network is restricted to transmit or receive is referred to as "inactive time".
[0003] Cell DTX / DRX is introduced to reduce the energy consumption of the whole network. In cell DTX / DRX configuration, the network can only transmit or receive data during the cell DTX / DRX active time, and only a few necessary signals or channels are transmitted and received during the cell DTX / DRX inactive time. For cell DTX / DRX, the longer the inactive duration, the better the energy saving effect will be. However, long inactive time can affect the user experience in the cell. For example, during the long inactive time, the user equipment (UE) can experience a longer delay time when reacting to a burst event due to the few signals or channels activated in the inactive time. Therefore, it is needed to improve the user experience in cell DTX / DRX by defining the UE behavior in the cell DRX / DTX scheme while maintaining reasonable energy saving gain. SUMMARY

The direct communication channels between the plurality of UEs 104 and one or more of the BSs 102 can be through an interface such as a Uu interface, also referred to as an E-UTRAN air interface. In some embodiments, the UEs 104 include multiple transceivers, which enables the UEs 104 to support multi-connectivity to receive data simultaneously from the first BS 102-1 and the second BS 102-2.

[0031] Figure 1B A block diagram of an exemplary wireless communication system 150 according to some embodiments of the present disclosure is shown. System 150 may include components and elements configured to support known or conventional operating features that do not need to be described in detail herein. In some embodiments, system 150 may be used in applications such as... Figure 1A In the wireless communication environment of the wireless communication network 100, data symbols are transmitted and received as described above.
[0032] System 150 typically includes a first BS102-1, a second BS102-2, and a UE 104, which will be collectively referred to as BS102 and UE 104 for ease of discussion. Both the first BS102-1 and the second BS102-2 include a BS transceiver module 152, a BS antenna array 154, a BS memory module 156, a BS processor module 158, and a network interface 160. In the illustrated embodiment, each module in BS102 is coupled and interconnected with each other via a data communication bus 180 as needed. UE 104 includes a UE transceiver module 162, a UE antenna 164, a UE memory module 166, a UE processor module 168, and an I / O interface 169. In the illustrated embodiment, each module in UE 104 is coupled and interconnected with each other via a data communication bus 190 as needed. BS102 communicates with UE 104 via a communication channel 192, which can be any wireless channel suitable for data transmission as described herein.
[0033] Those skilled in the art will understand that system 150 may also include, in addition to Figure 1B Any number of BS, UE, or modules other than those shown. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are typically described according to their functionality. Whether this functionality is implemented as hardware, firmware, or software depends on the specific application and the design constraints imposed on the system as a whole. Those skilled in the art can implement these functions appropriately for each specific application, but these implementation decisions should not be construed as limiting the scope of the invention.
[0034] Wireless transmissions from a transmit antenna of a UE 104 to a receive antenna of a BS 102 are referred to as uplink (UL) transmissions, and wireless transmissions from a transmit antenna of a BS 102 to a receive antenna of a UE 104 are referred to as downlink (DL) transmissions. According to some embodiments, the UE transceiver 162 can be referred to herein as an "uplink" transceiver 162, which includes radio frequency (RF) transmitter and receiver circuitry, each coupled to a UE antenna 164. A duplexing switch (not shown) alternatively couples the uplink transmitter or receiver to the uplink antenna in a time duplexed manner. Similarly, according to some embodiments, the BS transceiver 152 can be referred to herein as a "downlink" transceiver 152, which includes RF transmitter and receiver circuitry, each coupled to an antenna array 154. A downlink duplexing switch alternatively couples the downlink transmitter or receiver to the downlink antenna array 154 in a time duplexed manner. The operation of the two transceivers 152 and 162 are coordinated in time, such that the uplink receiver is coupled to the uplink UE antenna 164 to receive transmissions over the wireless communication channel 192 at the same time the downlink transmitter is coupled to the downlink antenna array 154. Preferably, there is tight synchronization timing with only minimal guard time between changes in duplex direction. The UE transceiver 162 communicates with the BS 102 via the UE antenna 164 over the wireless communication channel 192. The BS transceiver 152 communicates with other BSs (e.g., second BS 102-2) via the BS antenna 154 of the BS (e.g., first BS 102-1) over the wireless communication channel 196. The wireless communication channel 196 can be any wireless channel or other medium known in the art suitable for direct communication between BSs.
[0035] The UE transceiver 162 and the BS transceiver 152 are configured to communicate via the wireless data communication channel 192, and cooperate with appropriately configured RF antenna arrangements 154 / 164 that can support a particular wireless communication protocol and modulation scheme. In some example embodiments, the UE transceiver 162 and the BS transceiver 152 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards (e.g., NR). However, it should be understood that the present application is not necessarily limited to applications with particular standards and related protocols. Rather, the UE transceiver 162 and the BS transceiver 152 can be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.
[0036] The processor modules 158 and 168 can be implemented or realized with a general purpose processor, a content addressable memory, a digital signal processor, a application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of them designed to perform the functions described herein. In this manner, the processor modules can be implemented as a microprocessor, a controller, a microcontroller, a state machine, or the like. The processor modules also can be implemented as a combination of computing devices, e.g., a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration.
[0037] Furthermore, the steps of the methods or algorithms described in connection with the embodiments disclosed herein can be embodied directly in hardware, in firmware, in a software module executed by processor modules 158 and 168, or in any practical combination thereof. The memory modules 156 and 166 can be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disks, removable disks, CD-ROMs, or any other form of storage medium known in the art. In this regard, the memory modules 156 and 166 can be respectively coupled to the processor modules 158 and 168, such that the processor modules 158 and 168 can respectively read information from, and write information to, the memory modules 156 and 166. The memory modules 156 and 166 also can be integrated into their respective processor modules 158 and 168. In some embodiments, the memory modules 156 and 166 can each include flash memory for storing temporary variables or other intermediate information during execution of instructions to be respectively executed by the processor modules 158 and 168. The memory modules 156 and 166 also can each include non-volatile memory for storing instructions to be respectively executed by the processor modules 158 and 168.
[0038] The network interface 160 generally represents the hardware, software, firmware, processing logic and / or other components that enable the BS transceiver 152 to communicate with other network components and communication nodes configured to communicate with the BS 102. For example, the network interface 160 can be configured to support Internet or WiMAX traffic. In a typical deployment, the network interface 160 provides an 802.3 Ethernet interface, without limitation, such that the BS transceiver 152 can communicate with a conventional Ethernet-based computer network. In this manner, the network interface 160 can include a physical interface for connecting to a computer network (e.g., a Mobile Switching Center (MSC)). The term "configured to" or "configured for" as used herein with respect to a particular operation or function refers to a device, component, circuit, structure, machine, signal, etc. that is physically constructed, programmed, formatted, and / or arranged to perform the particular operation or function. The network interface 160 can allow the BS 102 to communicate with other BSs or a CN over wired or wireless connections.
[0039] Referring again to Figure 1A As noted above, the BS 102 repeatedly broadcasts system information associated with the BS 102 to one or more UEs 104 in order to allow the UEs 104 to access the network within the cell in which the BS 102 is located and generally operate normally within the cell. For example, a plurality of information such as downlink and uplink cell bandwidth, downlink and uplink configuration, cell information, random access configuration, etc. can be included in the system information. Generally, the BS 102 broadcasts a first signal carrying some primary system information (e.g., configuration of the cell in which the BS 102 is located) over a physical broadcast channel (PBCH). For purposes of clarity of illustration, this broadcasted first signal is referred to herein as a "first broadcast signal." It should be noted that the BS 102 can subsequently broadcast one or more signals carrying some other system information over a corresponding channel (e.g., a physical downlink shared channel (PDSCH)).
[0040] Referring again to Figure 1BIn some embodiments, the primary system information carried by the first broadcast signal can be transmitted by the BS 102 in a symbol format via the communication channel 192 (e.g., PBCH). According to some embodiments, the raw form of the primary system information can be presented as one or more sequences of digital bits, and the one or more sequences of digital bits can be processed through a number of steps (e.g., encoding, scrambling, modulating, mapping steps, etc.), all of which can be processed by the BS processor module 158, to become the first broadcast signal. Similarly, when the UE 104 receives the first broadcast signal (in the symbol format) using the UE transceiver 162, according to some embodiments, the UE processor module 168 can perform a number of steps (de-mapping, de-modulating, decoding steps, etc.) to estimate the primary system information, such as the bit positions of the bits of the primary system information, the number of bits, etc. The UE processor module 168 is also coupled to the I / O interface 169, which provides the UE 104 the ability to connect to other devices, such as a computer. The I / O interface 169 is the communication path between these accessories and the UE processor module 168.
[0041] Figure 2 A signaling diagram between a BS 202 and a UE 204 for performing cell DTX / DRX signal processing is shown, according to some embodiments. In some embodiments, the BS 202 can be configured to transmit a first signal 206 to the UE 204 for further cell DTX / DRX processing. Although Figure 2 An example of one UE 204 is shown in the middle, but the present disclosure is not limited to one single UE, and the BS 202 can transmit the first signal 206 to multiple UEs within a cell covered by the BS 202.
[0042] In some embodiments, the wireless communication node transmits the first signal 206, and / or the wireless communication device receives the first signal 206.

[0044] In some embodiments, the first signal is a DCI for indicating the indication information for a group of wireless communication devices or all wireless communication devices in a serving cell. Wherein all of the wireless communication devices represent the following wireless communication devices, which support a cell DTX and / or a cell DRX user equipment UE capability or UE feature in the serving cell, or all Release-18 UEs in the serving cell.
[0045] In some embodiments, the first signal comprises indication information comprising at least one of: activating and / or deactivating a cell DTX mode; activating and / or deactivating a cell DRX mode; and / or one or more information blocks.
[0046] In some embodiments, the information blocks carry indication information of the wireless communication devices. In some embodiments, the number of information blocks is equal to the number of wireless communication devices in the group of wireless communication devices. In some embodiments, each information block carries indication information of one wireless communication device in the group of wireless communication devices.
[0047] In some embodiments, the indication information comprises: a wake-up indication, a signal transmission indication, a timer trigger indication, a resource parameter, a flag indicating whether one or more fields in the DCI are re-interpreted or an indication of a type of power offset to be used, a field for indicating a selected power offset, a field for indicating one or more updated CSI resources, a field for indicating a start offset of a cell DTX / DRX cycle or user equipment, UE, connected discontinuous reception, CDRX, configuration related information, a field for indicating at least one of a number of ports used for CSI measurement or CSI reporting, one or more CSI-RS resource identifiers, one or more CSI-RS resource set identifiers, one or more CSI resource configuration identifiers, and a field for indicating activation or deactivation of a TCI state in a TCI state set.

For example, 1 / 2, 1 / 4, 1 / 8, 1 / 3, 3 / 8, 1, 2, 3, 4, 8. In some embodiments, the scaling factor is used to determine a second number of ports from a first number of ports; a power offset, where the indication information corresponds to a power control offset (powerControlOffset) or a power control offset SS (powerControlOffset SS); in some embodiments, the power control offset is a hypothetical ratio of PDSCH EPRE to NZP CSI-RS EPRE when the UE derives CSI feedback and takes values in the range of [-8, 15] dB with 1 dB step. In some embodiments, the power control offset SS is a hypothetical ratio of NZP (non-zero power) CSI-RS EPRE to SS / PBCH block EPRE (energy per resource element); an index, for example, the indication information is a CRI (CSI-RS resource indicator), a resource set ID, a resource setting ID; a TCI (transmission configuration indicator); a CDM (code division multiplexing); a resource mapping, for example, N1 corresponds to a number of ports in a first dimension and N2 corresponds to a number of ports in a second dimension; a CDM group index; a frequency domain resource; a time domain resource; a group index. In some embodiments, each information block indicates indication information for a group of wireless communication devices in a bitmap. In some embodiments, each information block in the bitmap is a resource parameter. In some embodiments, each bit in the bitmap is associated with one or more port indices, and a value of the bit indicates whether a corresponding port is active, valid, or indicated.
[0049] In some embodiments, the UE 204 receives configuration information from the BS 202, the configuration information including at least one of: one or more cell DTX modes, one or more cell DRX modes, one or more cell DTX / DRX modes, a cell DTX / DRX mode indication, and a cell DRX mode indication. The term “one or more DTX / DRX modes” can be referred to as one or more discontinuous modes including both DTX and DRX modes. Each of the one or more cell DTX modes can include at least one of: a cell DTX start offset, a cell DTX cycle, a cell DTX on duration timer associated with a cell DTX on duration, and a cell DTX inactivity timer, each of the one or more cell DRX modes can include at least one of: a cell DRX start offset, a cell DRX cycle, a cell DRX on duration timer associated with a cell DRX on duration, and a cell DRX inactivity timer, and each of the one or more cell DTX / DRX modes can include at least one of: a cell DTX / DRX start offset, a cell DTX / DRX cycle, a cell DTX / DRX on duration timer associated with a cell DTX / DRX on duration, and a cell DTX / DRX inactivity timer. The purpose of this configuration is for the BS 202 to communicate with the UE 204 and provide one or more cell DRX modes and / or one or more DTX / DRX modes such that the communication is activated only during a cell DRX on duration or a DTX / DRX on duration in a cell DRX cycle or a cell DTX / DRX cycle. In this way, the power consumption generated during the communication can be reduced.
[0050] In some embodiments, the cell DTX / DRX can also be written as cell DRX / DTX with the same meaning and no substantial difference.
[0051] In some embodiments, the BS 202 sends the first signal 206 to the UE 204 when at least one of the following conditions is met: the wireless communication device has a UE capability to support cell DTX; and / or the wireless communication device has a UE capability to support cell DRX; the second signal is sent by the wireless communication device or received by the wireless communication node; a cell DTX mode is to be changed; a cell DRX mode is to be changed; a cell DTX / DRX mode is to be changed; a start offset is to be changed, wherein the start offset comprises at least one of a cell DTX start offset, a cell DRX start offset, and a cell DTX / DRX start offset; a timer is to be activated, wherein the timer comprises at least one of: a cell DTX ON duration timer; a cell DTX inactivity timer; a cell DRX ON duration timer, a cell DRX inactivity timer, a cell DTX / DRX ON duration timer, and a cell DTX / DRX inactivity timer. As used herein, a “cell DRX ON duration timer” refers to a timer that counts a cell DRX ON duration in a particular cell DRX cycle. Details of the cell DRX ON duration and the cell DRX cycle will be described in more detail below with reference to Figure 3 Details of the cell DRX ON duration and the cell DRX cycle will be described in more detail below. A “cell DRX inactivity timer” refers to a timer that counts a DRX inactivity duration within a particular cell DRX cycle, where the DRX inactivity timer can be triggered in the particular cell DRX cycle. During the DRX inactivity duration, communication between the BS 202 and the UE 204 is active. In some embodiments, the DRX inactivity duration is associated with a UE request.
[0052] Figure 3Examples of two-cell DRX modes are shown in accordance with some embodiments. In some embodiments, a first cell DRX mode 302-1 includes a cell DRX cycle 304-1, a cell DRX on-duration 306-1, and a cell DRX off-duration 308-1, and a second cell DRX mode 302-2 includes a cell DRX cycle 304-2, a cell DRX on-duration 306-2, and a cell DRX off-duration 308-2. In one embodiment, the cell DRX cycle 304-1 has the same duration as the cell DRX cycle 304-2. In another embodiment, the cell DRX cycle 304-1 and the cell DRX cycle 304-2 have different durations. In yet another embodiment, the cell DRX on-duration 306-1 is different from the cell DRX on-duration 306-2, and the cell DRX off-duration 308-1 is different from the cell DRX off-duration 308-2. In some embodiments, information regarding one or more desired cell DRX modes and / or one or more desired cell DTX / DRX modes can be indicated by the UE 204 and sent to the BS 202.
[0053] Although Figure 3 Examples of two-cell DRX modes are shown in the above, the present disclosure is not limited to two-cell DRX modes, and different numbers of cell DRX modes with durations similar to those shown in the above can be used in the configuration information 206. Figure 3 One or more cell DTX modes, or one or more cell DTX / DRX modes, similar to those shown in the above. Those of ordinary skill in the art will appreciate that cell DTX modes can have on and off durations similar to those shown in the above. It is further appreciated that cell DTX modes can, but need not, be similar to cell DRX modes of sessions established between the BS 202 and the UE 204. Figure 3
[0054] In some embodiments, when one or more cell DTX modes are activated during a communication, downlink (DL) transmissions from the BS 202 to the UE 204 are controlled by the one or more cell DTX modes, and the DL transmissions only occur during the cell DTX on durations, while uplink (UL) traffic from the UE 204 to the BS 202 is not affected by the one or more cell DTX modes. In some other embodiments, when one or more cell DRX modes are activated during a communication, UL transmissions from the UE 204 to the BS 202 are controlled by the one or more cell DRX modes, and the UL transmissions only occur during the cell DRX on durations, while DL traffic from the BS 202 to the UE 204 is not affected by the one or more cell DRX modes. In yet some other embodiments, when both DTX and DRX modes are activated during a communication, DL transmissions from the BS 202 to the UE 204 can only occur during the cell DTX on durations, and UL transmissions from the UE 204 to the BS 202 can only occur during the cell DRX on durations.
[0055] Figure 4 Another signaling diagram between the BS 402 and the UE 404 for performing cell DTX / DRX signal processing is shown in accordance with some embodiments. In some embodiments, the UE 404 can be configured to send a second signal 406 to the BS 402 at a plurality of second signal transmission occasions to further conduct cell DTX / DRX processing. The plurality of second signal transmission occasions can be referred to as conditions and timings for sending the second signal 406. In some embodiments, the UE 404 can receive the first signal 206 from the BS 402 after sending the second signal 406. In some embodiments, the UE 404 can send the second signal 406 after receiving the first signal 206 and in response to information contained in the first signal 206. As discussed in further detail below, the second signaling requests a particular cell DTX, cell DRX, or cell DTX / DRX mode to be configured by the BS 402 to optimize or improve user experience (e.g., signal latency) during data transmissions measured or determined by the UE 404. If the second signal 406 is sent after the first signal 206, the second signal 406 can contain information for adjusting the cell DTX, cell DRX, and cell DTX / DRX previously configured by the BS 402. If the second signal 406 is sent first, the second signal 406 contains information for requesting a particular cell DTX, cell DRX, or cell DTX / DRX mode desired. In accordance with some embodiments, the BS 402 can grant the request from the UE 404 based on various factors (e.g., available communication resources, quality of service (QoS) parameters associated with the UE 404, etc.).
[0056] In some embodiments, the second signal 406 includes at least one intended cell DRX mode determined by the UE 404, wherein the at least one intended cell DRX mode is associated with at least one of a cell DRX mode index, a cell DRX start offset, an intended cell DRX cycle, an intended cell DRX on duration. In one embodiment, the UE 404 is configured to measure a communication delay (such as a packet delivery delay) and compare the measured communication delay with a first predetermined delay threshold. If the measured communication delay is greater than the first predetermined delay threshold, the UE 404 can determine an intended cell DRX mode with an intended cell DRX on duration that is longer than a predetermined nominal cell DRX on duration to reduce communication delay and improve communication efficiency. In another embodiment, if the measured communication delay is shorter than the first predetermined delay threshold, the UE 404 can determine an intended cell DRX mode with an intended cell DRX on duration that is shorter than a predetermined nominal cell DRX on duration to save power.
[0057] In some embodiments, the second signal 406 further includes at least one of a wake-up indication, a cell DRX mode indication, a cell DTX / DRX mode indication, a timer trigger indication, a signal transmission indication. In some embodiments, the second signal 406 further includes UE assistance information, wherein the UE assistance information includes at least one of a delay requirement, a preferred cell DRX mode, and a preferred cell DTX / DRX mode.
[0058] In some embodiments, the second signal 406 is carried by at least one of a physical random access channel (PRACH) preamble based signal, a physical uplink control channel (PUCCH) configuration, a scheduling request (SR), a buffer status report (BSR), a physical uplink shared channel (PUSCH) configuration, and a sequence or preamble based signal.

The second signal is associated with at least one of: a preamble format; a sequence generation method; a time domain resource allocation; a frequency domain resource allocation; a preamble index; a cell DRX mode index; or a cell DTX / DRX mode index. For some examples, the preambles used for random access and the preambles used as the second signal can be distinguished by the preamble format. For some other examples, the preambles used for random access and the preambles used as the second signal can be distinguished by the sequence generation method, which includes at least one of cyclic shift, sequence initialization, root sequence. For some other examples, each preamble is associated with a preamble index, and one or more preambles associated with a predefined index are used as the second signal. In some other examples, the second signaling is used to indicate a cell DRX mode or a cell DTX / DRX mode. There is one or more preambles for cell DRX mode or cell DTX / DRX mode indication, and each preamble is associated with one cell DRX mode or one cell DTX / DRX mode. The gNB receives the preamble and obtains the cell DRX mode indication or the cell DTX / DRX mode indication.
[0060] In some embodiments, the second signal is carried by PUCCH. The second signal is associated with at least one of: a PUCCH format; a PUCCH resource ID; a PUCCH resource set ID; a UCI length. In some examples, the second signal is configured with a predefined PUCCH format. At least one of an initial cyclic shift (initialCyclicShift), a number of symbols (nrofSymbol), a starting symbol index (startingSymbolIndex) is different from the PUCCH used for HARQ-ACK, SR and CSI reporting. In some other examples, the second signal is configured with one or more PUCCH resources with specific resource ID. In some other examples, the second signal is configured with one or more PUCCH resource sets with specific resource set ID.
[0061] In some embodiments, the second signal is a SR (scheduling request). When the SR requests UL-SCH resource for new transmission, the wake-up indication information or timer trigger information for cell DRX or cell DTX / DRX is sent.
[0062] In some embodiments, the second signaling is a BSR. When the BSR with information about UL data amount is sent, the wake-up indication information or timer trigger information for cell DRX or cell DTX / DRX is sent.
[0063] In some embodiments, the second signaling is carried by PUSCH.
[0064] In some embodiments, the second signaling is a sequence or preamble based signal including at least one of: a binary sequence or preamble; a sequence or preamble modulated with OOK, ASK, FSK; a sequence or preamble and a data or payload portion.
[0065] In some embodiments, the UE 404 is configured to measure a communication delay, such as a packet delivery delay, and compare the measured communication delay to a second predetermined delay threshold, where the second predetermined delay threshold is greater than the first predetermined delay threshold. If the measured communication delay is greater than the second predetermined delay threshold, the UE 404 can determine that the communication quality is not acceptable and can not use the cell DTX / DRX to maintain the communication quality. In this case, the UE 404 can indicate not to start the cell DRX on-duration timer or the cell DTX / DRX on-duration timer. In some embodiments, the wake-up indication is to indicate at least one of: to start the cell DRX on-duration timer based on a desired DRX period, to start the cell DTX / DRX on-duration timer based on a desired DTX / DRX period, not to start the cell DRX on-duration timer, and not to start the cell DTX / DRX on-duration timer.
[0066] In some embodiments, the second signal includes an indication to start the cell DRX on-duration timer. The UE does not send the second signal when the cell DRX on-duration timer does not need to be started. In some embodiments, the UE sends the second signal to indicate to start the cell DTX / DRX on-duration timer. The UE does not send the second signaling when the cell DTX / DRX on-duration timer does not need to be started.
[0067] In some embodiments, the wake-up indication includes a “0” value and a “1” value, where the “0” value indicates not to start the cell DRX on-duration timer and the “1” value indicates to start the cell DRX on-duration timer. In some other embodiments, the wake-up indication includes a “0” value and a “1” value, where the “0” value indicates not to start the cell DTX / DRX on-duration timer and the “1” value indicates to start the cell DTX / DRX on-duration timer.
[0068] In some embodiments, the second signal 406 is a sequence-based signal, such as a preamble-based signal. In one embodiment, the second signal 406 includes a plurality of second signal sequences, where each of the plurality of second signal sequences is associated with a corresponding cell DRX mode or a corresponding cell DTX / DRX mode. In some other embodiments, the second signal 406 is a channel-based signal carried by a PUCCH or a PUSCH. In one exemplary embodiment, the second signal 406 includes a sequence of 3 bit streams: bit stream 1, bit stream 2, and bit stream 3, where bit stream 1 includes a plurality of first bits representing a cell DRX period, bit stream 2 includes a plurality of second bits representing a cell DRX on-duration, and bit stream 3 includes a plurality of third bits representing a cell DRX inactive duration.
[0069] In some embodiments, the second signal 406 includes a cell DRX mode indication field or a cell DTX / DRX mode indication field, where the cell DRX mode indication field or the cell DTX / DRX mode indication field is a bitmap, where each bit in the bitmap corresponds to a cell DRX mode or a cell DTX / DRX mode. In one embodiment, each bit in the bitmap can be a “1” value for a cell DRX mode indication or a cell DTX / DRX mode indication, or a “0” value for a cell DRX mode indication or a cell DTX / DRX mode indication, where the “1” value indicates that the corresponding cell DRX mode or the corresponding cell DTX / DRX mode is available or preferred, and the “0” value indicates that the corresponding cell DRX mode or the corresponding cell DTX / DRX mode is not available or not preferred. In some other embodiments, the cell DRX mode indication field or the cell DTX / DRX mode indication field is a codepoint for indicating a preferred cell DRX mode index or a preferred cell DTX / DRX mode index. In one exemplary embodiment, the second signal 406 includes 3 codepoints: codepoint 1, codepoint 2, and codepoint 3, where codepoint 1 includes a first plurality of American Standard Code for Information Interchange (ASCII) codes representing a cell DRX period, codepoint 2 includes a second plurality of ASCII codes representing a cell DRX on-duration, and codepoint 3 includes a third plurality of ASCII codes representing a cell DRX inactive duration.
[0070] In some embodiments, the gNB determines a cell DRX mode to be used according to the second signal information reported by UEs configured with the same cell DRX mode. In some embodiments, the gNB determines a cell DTX / DRX mode to be used according to the second signal information reported by UEs configured with the same cell DTX / DRX mode.
[0071] In some embodiments, the UE complies with the updated cell DRX pattern or cell DTX / DRX pattern after receiving the feedback of the second signaling from the gNB. In some examples, the updated cell DRX pattern or cell DTX / DRX pattern takes effect after receiving the signaling from the gNB, where the signaling includes at least one of the RRC, the DCI, the feedback of the second signaling. In some examples, the updated cell DRX pattern or cell DTX / DRX pattern takes effect after a time period from receiving the signaling from the gNB, where the signaling includes at least one of the RRC, the DCI, the feedback of the second signaling, and the time period is an offset configured by the RRC or predefined. In some other examples, the updated cell DRX pattern or cell DTX / DRX pattern takes effect from the next cell DRX on duration after receiving the signaling from the gNB, where the signaling includes at least one of the RRC, the DCI, the feedback of the second signaling.
[0072] Figure 5 An example of a cell DRX inactivity timer used in a cell DRX pattern is shown in accordance with some embodiments. In some embodiments, Figure 4 The UE 404 shown in FIG. 5 can be configured with a first cell DRX pattern 502-1. When the cell DRX inactivity timer is configured by the RRC, the cell DRX inactivity timer can be triggered to extend the cell DRX on duration. The cell DRX inactivity timer can be triggered by the UE 404. The UE 404 can acquire the following information: the communication quality is not acceptable; an uplink service burst occurs, the DRX on duration 506-1 in the first cell DRX pattern 502-1 is not long enough; and the DRX on duration 506-1 needs to be extended to improve the communication quality. In this case, the UE 404 can trigger the cell DRX inactivity timer at the time point 510 in the second cell DRX pattern 502-2 when a time duration 516-2 elapses in the cell DRX on duration 506-2 from the second cell DRX pattern 502-2, where the cell DRX inactivity timer is associated with a timer duration 512. The sum of the time duration 516-2 and the timer duration 512 can be greater than the cell DRX on duration 506-1. Thus, when the cell DRX inactivity timer is triggered at the time point 510, the cell DRX on duration 506-1 can be extended to the cell DRX on duration 506-2, and the cell DRX off duration 508-2 in the second cell DRX pattern 502-2 becomes shorter than the cell DRX off duration 508-1 in the first cell DRX pattern 502-1. In some embodiments, the cell DRX inactivity timer is configured for a specific UE. In some other embodiments, the cell DRX inactivity timer is configured for a group of UEs within a cell covered by the BS.
[0073] In some embodiments, the second signaling includes a timer trigger indication. The timer trigger indication is used to indicate to start or restart a cell DRX inactivity timer, or to start or restart a cell DTX / DRX inactivity timer, to stop a cell DRX inactivity timer, to stop a cell DTX inactivity timer. In some examples, the cell DRX inactivity timer is a UE specific timer. In some examples, the UE starts or restarts the cell DRX inactivity timer after sending the second signaling. In some other examples, the UE starts or restarts the cell DRX inactivity timer after receiving feedback of the second signaling from the gNB. In some other examples, the cell DRX inactivity timer is configured for a group of UEs or all UEs configured with the same cell DRX mode. In some other examples, the UE starts or restarts the cell DRX inactivity timer after receiving feedback of the second signaling from the gNB. In some examples, the cell DTX / DRX inactivity timer is a UE specific timer. In some examples, the UE starts or restarts the cell DTX / DRX inactivity timer after sending the second signaling.

In some other examples, the UE starts or restarts the cell DTX / DRX inactivity timer after receiving feedback of the second signaling from the gNB.
[0074] In some embodiments, the second signaling includes a time offset / duration indication, where the time offset / duration is used to indicate when to start or restart a timer, including a cell DRX on duration timer, a cell DTX / DRX on duration timer, a cell DRX inactivity timer, a cell DTX / DRX inactivity timer. In some embodiments, the second signaling includes a time offset / duration indication, where the time offset / duration is used to indicate the (remaining) time for the UE to send a UL signal / channel.
