Background

With the further evolution of the fifth generation mobile communication (5 th-generation, 5G) technology, the improvement of network energy efficiency is a current hot topic. The energy consumption of the base station is higher in the network energy consumption, and the network energy efficiency can be improved by reducing the energy consumption of the base station.

The power consumption of a base station can be generally divided into two parts, wherein one part is dynamic power consumption, and the dynamic power consumption changes along with the change of the service and the data volume of a terminal, such as data transmission and the like. Part of the static energy consumption (no matter how large the network is loaded, the part of the energy consumption is needed to be consumed by the base station at present) mainly comprises static receiving energy consumption and static sending energy consumption, wherein the static receiving energy consumption mainly comprises message 1 (Msg 1) of random access received by the network on configured random access resources, and the static sending energy consumption mainly comprises sending of synchronous signal blocks (synchronization signal and PBCH block, SSB), paging sending, sending of system information blocks (system information block, SIB) and the like. How to optimize the static energy consumption of the base station is one of the effective ways to improve the energy efficiency of the base station, and is a problem to be solved by those skilled in the art.

Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The terminology used in the following embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates to the contrary. It should also be understood that the term "and/or" as used in this disclosure refers to and encompasses any or all possible combinations of one or more of the listed items.

It should be noted that the terms "first," "second," "third," and the like in the description and claims of the present application and in the following drawings are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the order of use may be interchanged under appropriate circumstances such that the embodiments of the application described herein may be practiced otherwise than as illustrated or described. Furthermore, the terms "comprises," "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the present application may be applied to the network architecture shown in fig. 1, where the network architecture shown in fig. 1 is a network architecture of a wireless communication system, and the network architecture generally includes a terminal and a network device, and the number and the form of each device do not limit the embodiment of the present application. Three network devices (network device 1, network device 2, network device 3) and one terminal are schematically shown in fig. 1. The network device 1, the network device 2, and the network device 3 can provide communication services for the terminal. The terminal may select a cell corresponding to one of the network devices to camp on (illustrated in fig. 1 as network device 2). Among them, the network device 1 may be referred to as an anchor base station, the carrier used by the network device 1 may be referred to as an anchor carrier (anchor carrier), and the coverage thereof may be referred to as an anchor cell (non-anchor cell). The network devices 2 and 3 may be referred to as non-anchor base stations, and the carriers used by the network devices 2 and 3 may be referred to as non-anchor carriers (non-anchor carriers), and the coverage area thereof may be referred to as non-anchor cells (non-anchor cells). Alternatively, the anchor cell and the non-anchor cell may be provided by the same network device. Anchor carriers (or cells) and non-anchor carriers (or cells) are further described below. These concepts were first proposed for the purpose of network energy conservation (network energy savings, network power saving). In a 5G network, for example, because of more spectrum resources, such as frequency bands (bands) including 1 gigahertz (GHz), 2GHz, 4GHz, 6GHz, and 26GHz, when the network load is low, carriers or cells corresponding to some frequency bands (such as 4GHz, 6GHz, or 26 GHz) may be turned off as much as possible and turned on as required, so as to achieve the purpose of network energy saving. That is, some carriers or cells do not need to carry data when the network load is low. It will be appreciated that the purpose of network power conservation may be achieved by switching on and off certain carriers, but this is typically achieved when the network load is low.

Such carriers or cells that are controlled by the network and may be opened as needed may be referred to as non-anchor carriers or non-anchor cells, or as second type carriers or second type cells, or as secondary carriers (secondary carrier) or secondary cells (scells), and in the embodiment of the present application, may also be referred to as second carriers. It should be noted that, as the communication technology evolves, such carriers or cells may also have other names. In contrast, a carrier or cell that is not turned off may be referred to as an anchor carrier or anchor cell, or as a first type carrier or first type cell, or as a primary carrier (primary carrier) or primary cell (PCell), and in the embodiment of the present application, is also referred to as a first carrier. It should be noted that, as the communication technology evolves, such carriers or cells may also have other names.

Generally, the coverage of a non-anchor carrier (or cell) is within the coverage of an anchor carrier (or cell). In other words, the coverage of an anchor carrier (or cell) includes the coverage of one or more non-anchor carriers (or cells). Anchor carriers provide a wide range of coverage, while non-anchor carriers have a smaller coverage and provide high-speed data transmission services. Currently there is still a need for non-anchor carriers or cells to transmit measurement reference signals to support access and mobility of terminals.

It should be noted that, the wireless communication system mentioned in the embodiments of the present application includes, but is not limited to: an internet of things system (internet of things, ioT), a long term evolution system (long term evolution, LTE), a 5G system, a New Radio (NR) system, a sixth generation mobile communication (6 th-generation, 6G) system, and a future mobile communication system.

The chip system may include a chip and may also include other discrete devices, which are not limited by the embodiment of the present application.

In the embodiment of the application, the network device is a device for providing a wireless communication function for the terminal, and may also be called a radio access network (radio access network, RAN) device, an access network element, or the like. Wherein the network device may support at least one wireless communication technology, e.g., LTE, NR, etc. By way of example, network devices include, but are not limited to: a next generation base station (gcb), evolved node B (eNB), radio network controller (radio network controller, RNC), node B (NB), base station controller (base station controller, BSC), base transceiver station (base transceiver station, BTS), home base station (e.g., home evolved node B, or home node B, HNB), baseband unit (BBU), transceiving point (transmitting and receiving point, TRP), transmitting point (transmitting point, TP), mobile switching center, and the like in 5G.

By way of example, the chip system may include a chip, and may also include other discrete devices. In some embodiments, the network device may also communicate with an internet protocol (Internet Protocol, IP) network, such as the internet, a private IP network, or other data network, among others.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided by the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided by the embodiments of the present application is applicable to similar technical problems.

Next, some concepts related to the embodiments of the present application will be described.

1. Paging (Paging)

Paging refers to the act of the network calling a terminal by sending a paging message (paging message), which may cause the terminal being paged to initiate a signaling connection establishment procedure with the network.

The case of the network sending the paging message mainly comprises:

(1) Transmitting a call request to a terminal in a radio resource control IDLE (radio resource control IDLE, rrc_idle) state and a radio resource control deactivated (radio resource control INACTIVE, rrc_inactive) state;

(2) Notifying the terminal in the rrc_idle/rrc_inactive state and the radio resource control CONNECTED (radio resource control CONNECTED, rrc_connected) state that system information has changed;

(3) The terminal is instructed to start receiving the earthquake and tsunami warning system (earthquake and tsunami warning system, ETWS) notification and/or to start receiving the commercial mobile warning system (commercial mobile alert system, CMAS) notification.

2. Random Access (RA)

Referring to fig. 2, a schematic flow chart of random access is provided in an embodiment of the present application. The terminal first acquires random access resource configuration information including time-frequency resources for transmitting a random access request message, a contention random access preamble range (this preamble range may be a sequence index range of a preamble), etc., by reading the system message block 1 (System Information Block, sib1). The terminal sends a random access Msg1, also referred to as a random access request message, to the network device to initiate random access to the network. The Msg1 contains a preamble (preamble) of random access. If the network device correctly receives the Msg1, a random access message 2 (Msg 2), also referred to as a random access response message, scrambled with a random access radio network temporary identity (random access radio network temporary identifier, RA-RNTI) is sent to the terminal. After transmitting the Msg1, the terminal may monitor the Msg2 from the network device using the RA-RNTI to descramble the message. Msg2 may contain a timing offset (TA), a radio network temporary identity (temporary cell radio network temporary identifier, TC-RNTI) of the temporary cell, a power control (power control) and a resource indication of the terminal sending message 3 for random access (Mgs). The terminal then transmits Mgs a resource indication to the network device based on the transmission Mgs3. Finally, if the network device correctly receives the Msg3, the network device sends a random access message 4 (Msg 4), which may also be referred to as a contention resolution message, to the terminal to inform the completion of the initial access procedure. If the terminal does not successfully receive the Msg4, the terminal can determine that the initial access procedure fails.

At this stage, since the network device does not know where the specific location of the terminal is in the rrc_idle state and the rrc_inactive state, when there is a terminal to be paged, the network device needs to send a paging message to the terminal through the first carrier. In this way, the static transmission of the network device consumes more power. In view of this, the scheme of the present application is provided, in which the network device sends the paging message through the first carrier after receiving the first preamble from the terminal, and it is not necessary to send the paging message always through the first carrier, so that the static sending energy consumption of the network device can be reduced, and the energy efficiency of the network device is improved.

In combination with the above description, the following further describes the solution of the embodiment of the present application. Referring to fig. 3, a flowchart of a communication method according to an embodiment of the present application is provided. The method can be applied to the network architecture shown in fig. 1, the network device may be the network device 1 in fig. 1, and the terminal may be the terminal in fig. 1. The method comprises the following steps:

s101, a terminal sends a first preamble to a network device through a first carrier, wherein the first preamble is one of a preamble subset, the preamble subset comprises one or more preambles, and the preamble in the preamble subset is used for indicating the network device to send a paging message through the first carrier. Accordingly, the network device receives the first preamble over the first carrier. Correspondingly, the network device receives the first preamble sent by the terminal through the first carrier.

Wherein the coverage area of the second carrier is within the coverage area of the first carrier. The second carrier may refer to the description of the non-anchor carrier in the foregoing, and the first carrier may refer to the description of the anchor carrier in the foregoing, which is not repeated herein. As can be seen from the foregoing description, the first carrier is generally not turned off, i.e. the terminal is always served, and the first preamble transmitted over the first carrier is reliable.

For contention random access (contention based random access, CBRA), the preamble employed by the terminal is randomly selected by the terminal within a contention random access preamble range broadcasted by SIB1, which may be referred to as a contention random access preamble subset. For non-contention random access (CFRA), the preamble used by the terminal is a dedicated preamble allocated to the terminal by the network device, and the dedicated preamble indicated by the network device is selected from a subset of non-contention random access preambles. Optionally, the preamble in the preamble subset in the embodiment of the present application may be selected from the contention random access preamble subset, or may be selected from the non-contention random access preamble subset, or may be selected from a part of the preambles in the two subsets, respectively.

It should be noted that, in the embodiment of the present application, the preamble in the preamble subset is used to instruct the network device to send the paging message through the first carrier, and the function of random access request is no longer provided, that is, the preamble is no longer used to send the random access request message. In other words, if the network device correctly receives the preamble in the preamble subset in the embodiment of the present application, msg2 will not be sent to the terminal in response to the preamble.

Optionally, before step S101, the network device sends system information, where the system information includes first indication information, where the first indication information is used to indicate the preamble subset. Accordingly, the terminal receives system information from the network device. In this way, the network device may inform the terminal of the subset of preambles via a system message. The terminal may select any one preamble from the preamble subset as the first preamble. Optionally, the system information may be system information sent by the network device through the first carrier, or may be system information sent by the network device through the second carrier. Alternatively, the first indication information may be included in other information or messages, which is not limited by the present application.

Optionally, the manner in which the terminal sends the first preamble to the network device through the first carrier is: if the second carrier wave meeting the cell residence condition does not exist, the terminal sends the first lead code to the network equipment through the first carrier wave; the signal quality of the reference signal on the second carrier meeting the cell residence condition is higher than a preset threshold, and the second carrier supports paging. It should be noted that, the second carrier supports paging, which means that the network device may send a paging message to the terminal through the second carrier, and the terminal may receive the paging message through the second carrier. In particular, the signal quality may also be understood as signal strength, and the reference signal received power (Reference Signal Receiving Power, RSRP) may be a reference indicator of the signal quality. Other reference indicators may also be present for the signal quality, as the application is not limited in this regard. The preset threshold may be specified by a protocol, or preset, or indicated by a network device, and the present application is not limited.

The above manner may be understood as that the terminal preferentially receives the paging message through the second carrier that satisfies the cell residence condition and supports paging. The terminal transmits a first preamble to the network device to instruct the network device to transmit a paging message through the first carrier, in the absence of a second carrier that satisfies the cell-camping condition and supports paging. In this way, the network device sends the paging message through the first carrier after receiving the first preamble from the terminal, and the paging message is not always sent through the first carrier, so that the energy consumption of the network device can be reduced, and the energy efficiency of the network device is improved.

In one possible scenario, the network devices corresponding to the first carrier and the second carrier are the same network device, which is exemplified as network device 1. In this implementation, the network device 1 sends a paging message to the terminal over a second carrier, in particular a second carrier supporting paging, before receiving the first preamble. After receiving the first preamble, the network device 1 sends the paging message to the terminal through the first carrier, so that the network device 1 does not need to send the paging message on both the first carrier and the second carrier, and the energy consumption of the network device can be reduced, thereby improving the energy efficiency of the network device.

In another possible scenario, the network devices corresponding to the first carrier and the second carrier are different network devices, for example, the first carrier corresponds to the network device 1 and the second carrier corresponds to the network device 2 and the network device 3. In this implementation, the network device 1 does not send a paging message to the terminal before the network device 1 receives the first preamble, but rather the network device 2 and/or the network device 3 sends the paging message to the terminal via the second carrier, in particular the second carrier supporting paging. After the network device 1 receives the first preamble, the network device 1 sends the paging message to the terminal through the first carrier, so that the network device 1 does not need to send the paging message on the first carrier all the time, and the energy consumption of the network device can be reduced, thereby improving the energy efficiency of the network device.

S102, if the paged terminal exists, the network equipment sends a paging message through the first carrier.

Correspondingly, the terminal receives the paging message from the network device through the first carrier.

In the method shown in fig. 3, the network device sends the paging message through the first carrier after receiving the first preamble from the terminal, and it is not necessary to send the paging message through the first carrier all the time, so that the energy consumption of the network device can be reduced, and the energy efficiency of the network device is improved.

Referring to fig. 4, a flowchart of a communication method according to an embodiment of the present application is provided. The method can be applied to the network architecture shown in fig. 1, the network device may be the network device 1 in fig. 1, and the terminal may be the terminal in fig. 1. The method comprises the following steps:

s201, the network equipment sends a system message, wherein the system message comprises first indication information, and the first indication information is used for indicating the preamble subset. Correspondingly, the terminal receives the system message.

Optionally, the network device sends the system information by broadcasting. The preamble subset may be referred to the description in step S101.

Optionally, the system information further includes third indication information, where the third indication information is used to indicate a correspondence between the preamble in the preamble set and SSB on the first carrier. Wherein the coverage area of the second carrier is within the coverage area of the first carrier. The second carrier may refer to the description of the non-anchor carrier in the foregoing, and the first carrier may refer to the description of the anchor carrier in the foregoing, which is not repeated herein. In this manner, the network device may inform the terminal of the correspondence between the preambles in the preamble set and the SSB on the first carrier through a system message. Alternatively, the correspondence may be included in other information or messages, which is not limited by the present application.

Note that, in this correspondence, one preamble may correspond to SSBs on one or more first carriers. The manner in which "one preamble corresponds to SSBs on one first carrier" may have a finer correspondence than the manner in which "one preamble corresponds to SSBs on a plurality of first carriers". In the case that the number of SSBs on the first carrier is fixed, the "one preamble corresponds to SSBs on a plurality of first carriers" manner, compared with the "one preamble corresponds to SSBs on one first carrier" manner, the number of preambles required in the preamble set is smaller, so that more preambles that can be used can be reserved for the random access procedure.

In one possible implementation, if the number of SSBs on the first carrier is smaller than a preset value, a "one preamble corresponds to SSBs on one first carrier" manner may be adopted, and if the number of SSBs on the first carrier is greater than or equal to the preset value, a "one preamble corresponds to SSBs on multiple first carriers" manner may be adopted. The preset value may be specified by a protocol, or preset, or indicated by other devices, which is not limited by the present application. Alternatively, in practical application, there may be other determining manners of the correspondence, which is not limited by how the embodiment of the present application determines the correspondence.

For example, the correspondence may refer to the example of table 1. In the example in table 1, one preamble of the preamble set may correspond to SSBs on one or more first carriers.

TABLE 1

Preamble setCombined preamble	SSB on a first carrier
		Preamble0	SSB0
Preamble1	SSB1、SSB2、SSB3
		Preamble2	SSB4、SSB5
Preamble3	SSB6
		Preamble4	SSB7、SSB8

S202, the terminal sends a first preamble to the network equipment through a first carrier, wherein the first preamble is one of preamble subsets. Accordingly, the network device receives the first preamble from the terminal through the first carrier.

Optionally, in the case that the preamble in the preamble set has a correspondence with the SSB on the first carrier, the first preamble corresponds to the SSB with the best signal quality on the first carrier. That is, the terminal selects, as the first preamble, a preamble corresponding to the SSB having the best signal quality on the first carrier from the preamble subset. It will be appreciated that the terminal is more likely to successfully receive the paging message sent by the network device in the beam direction of the SSB with the best signal quality on the first carrier than the other SSBs on the first carrier. In this manner, the terminal may inform the network device of the SSB with the best signal quality on the first carrier through the first preamble, so that the network device sends the paging message through the SSB with the best signal quality on the first carrier. In this way, the network device only needs to send the paging message in the direction of the SSB on the first carrier corresponding to the first preamble, so that the success rate of the terminal for receiving the paging message can be ensured, and compared with the case that the network device sends the paging message in the directions of all the SSBs on the first carrier, the power consumption of the network device can be obviously reduced, thereby improving the energy efficiency of the network device.

In some embodiments, after the terminal determines that there is no second carrier that satisfies the cell residence condition and supports paging, the terminal may determine, based on a measurement result of the terminal on the first carrier, an SSB with the best signal quality on the first carrier; and then selecting a preamble corresponding to the SSB with the best signal quality on the first carrier from the preamble subset as the first preamble. The description of the second carrier and the signal quality supporting paging satisfying the cell residence condition may refer to the description in step S101, and will not be repeated here.

S203, after the terminal sends the first preamble to the network equipment through the first carrier, the terminal starts a timer. Accordingly, the network device starts a timer after receiving the first preamble from the terminal.

The duration unit of the timer may be a paging cycle, a millisecond, a frame, a subframe, etc. Optionally, the system information received by the terminal from the network device further includes second indication information, where the second indication information is used to indicate a duration of the timer. Alternatively, the second indication information may be included in other information or messages, which is not limited by the present application. Optionally, the duration of the timer may be specified by a protocol, or preset, which is not limited by the present application.

Optionally, the duration of the timer of the terminal may be the same as or different from the duration of the timer of the network device. Optionally, the duration of the timer of the terminal is smaller than the duration of the timer of the network device.

S204, if the paged terminal exists in the running period of the timer of the network equipment, the network equipment sends a paging message through the first carrier. Accordingly, during the timer running of the terminal, the terminal receives the paging message through the first carrier.

In some embodiments, during the timer run of the terminal, the terminal may also receive a reference signal over the second carrier to find the second carrier that satisfies the cell-camping condition. Alternatively, the terminal may receive the reference signal only through the second carrier supporting paging to find the second carrier satisfying the cell residence condition. If the second carrier wave meeting the cell residence condition is found, after the timer of the terminal is overtime, the terminal receives the paging message through the second carrier wave meeting the cell residence condition. If the second carrier wave meeting the cell residence condition is not found and the timer of the terminal is overtime, the first lead code is sent to the network equipment through the first carrier wave again so as to inform the network equipment to continue sending the paging message through the first carrier wave. After the terminal transmits the first preamble again, the terminal starts a timer again.

For the network device, if the first preamble is received again during the running of the timer of the network device, which indicates that the terminal does not find the second carrier wave meeting the cell residence condition, the network device restarts the timer of the network device and continues to send the paging message through the first carrier wave. If the first preamble is not received again during the timer running of the network device and the timer times out, indicating that the terminal has found the second carrier meeting the cell residence condition, the network device stops sending the paging message through the first carrier. Optionally, in order to enable the paging message of the terminal to be successfully sent at each time, the duration of the timer of the terminal is smaller than the duration of the timer of the network device.

In this way, after the network device receives the first preamble from the terminal, the paging message is sent only through the first carrier during the running period of the timer, and the paging message is not always sent through the first carrier, so that the static sending energy consumption of the network device can be reduced, and the energy efficiency of the network device is improved.

In some embodiments, in the case that the preamble in the preamble set has a correspondence with the SSB on the first carrier, the first preamble corresponds to the SSB on the first carrier with the best signal quality. In this manner, if there is a terminal to be paged, the specific manner in which the network device sends the paging message through the first carrier is: if the paged terminal exists, the network equipment sends the paging message in the SSB direction corresponding to the first preamble. The direction of the SSB can be understood as the beam direction of the SSB. The specific way for the terminal to receive the paging message through the first carrier is as follows: the terminal receives the paging message in the direction of the SSB corresponding to the first preamble. By the method, the success rate of the terminal for receiving the paging message can be guaranteed, and compared with the case that the network equipment sends the paging message in all SSB directions on the first carrier, the power consumption of the network equipment can be obviously reduced, so that the energy efficiency of the network equipment is improved.

In some cases, the first preamble corresponds to SSBs of a plurality. If there is a terminal to be paged, the network device sends the paging message in the directions of the SSBs corresponding to the first preamble, because the network device does not know the location of the terminal, and cannot determine which SSB is best in signal quality detected for the terminal, and in order to ensure the success rate of the terminal receiving the paging message, the network device sends the paging message in the directions of the SSBs corresponding to the first preamble. For the terminal, the paging message may be received only in the direction of the SSB with the best signal quality on the first carrier, so as to reduce the power consumption of the terminal.

In the method shown in fig. 4, after the network device receives the first preamble from the terminal, the paging message is sent only through the first carrier during the running period of the timer, and the paging message is not always sent through the first carrier, so that the energy consumption of the network device can be reduced, and the energy efficiency of the network device is improved.
