Description

Method for controlling terminal energy saving, network side equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for controlling terminal energy saving, a network side device, and a terminal.

Background

With the wide application of the intelligent terminal, reducing the power consumption of the intelligent terminal becomes an important subject. In a process of communication between a network side device (e.g., a base station) and a UE (terminal), data is transmitted between the network side device and the UE on resources such as a carrier or a BWP (Bandwidth partial). When the amount of data that needs to be transmitted by both communication parties is small, the base data can be transmitted on a single carrier or on a BWP with a small bandwidth. When the amount of data that both communication parties need to transmit is large, the base data needs to be transmitted through BWP with a relatively large bandwidth. At this time, the number of activated carriers may be increased.

Therefore, when there is no data to be transmitted or the amount of data to be transmitted is small, the UE may detect only a Physical Downlink Control Channel (PDCCH) on the BWP with a relatively small bandwidth, and thus the power consumption of the UE is low at this time. When the amount of data to be transmitted is large, the UE needs to detect the PDCCH on the BWP with a large bandwidth, which results in high power consumption. When the traffic of the UE changes, the UE may adjust the bandwidth by activating or deactivating BWP.

In the related art, indication information for activating or deactivating BWP is carried in DCI (Downlink control information). The method specifically comprises the following steps: the network side device sends DCI containing indication information for activating or deactivating the BWP to the terminal at a first moment, and the network side device can send data on the activated BWP at a second moment. When there is no data to be transmitted, the network side device cannot send DCI to the terminal, and the terminal cannot complete BWP deactivation, so that power consumption of the terminal is high.

Disclosure of Invention

Embodiments of the present invention provide a method for controlling terminal energy saving, a network side device, and a terminal, so as to solve the problem in the prior art that when there is no data to be transmitted, the terminal cannot complete BWP deactivation, which results in large power consumption.

In a first aspect, an embodiment of the present invention provides a method for controlling a terminal to save energy, where the method includes:

and the network side equipment sends the energy-saving information.

The embodiment of the invention provides a method for controlling terminal energy saving, wherein network side equipment configures energy saving information on at least one first resource, and the energy saving information comprises activation or deactivation information of at least one second resource. Wherein the first resource is used for carrying the second resource, and the first resource and the second resource may be a carrier and/or BWP. And the network side equipment sends the energy-saving information to the terminal. Even when there is no data to be transmitted, the network side device may send the energy saving information to the terminal, so that the terminal determines the at least one activated or deactivated second resource according to the energy saving information. When the service changes, the terminal can adjust the bandwidth by activating or deactivating the second resource in time, so that the power consumption of the terminal is saved.

In one possible implementation manner, the energy saving information includes first indication information for indicating that at least one carrier is in an activated or deactivated state; and/or second indication information for indicating that at least one BWP is in an activated or deactivated state.

In the above method, the network side device may configure the activation or deactivation information of the carrier and the activation or deactivation information of the BWP independently. Specifically, only the first indication information indicating that the at least one carrier is in the activated or deactivated state may be included in the power saving information, only the second indication information indicating that the at least one BWP is in the activated or deactivated state may be included in the power saving information, or both the first indication information indicating that the at least one carrier is in the activated or deactivated state and the second indication information indicating that the at least one BWP is in the activated or deactivated state may be included in the power saving information. By the method, the activation or deactivation states of a plurality of second resources can be indicated on one first resource, and when one second resource is not required to be activated or deactivated, one piece of energy-saving information is sent by one first resource, so that the signaling overhead can be greatly reduced.

In the above method, the network side device may combine the activation or deactivation information of the configuration carrier and the BWP. I.e. the power saving information comprises third indication information for indicating that at least one BWP on at least one carrier is in an activated or deactivated state. By the method, the activation or deactivation states of a plurality of second resources can be indicated on one first resource, the second resources comprise carriers and BWPs, and when one second resource does not need to be activated or deactivated, one piece of energy-saving information is sent by one first resource alone, so that the signaling overhead can be greatly reduced.

the network side device places carrier identification information corresponding to the carrier needing to be activated or deactivated and BWP identification information corresponding to the BWP needing to be activated or deactivated in the third indication information; or

And the network side device places the number of the carriers needing to be activated and the BWP identification information corresponding to the BWP needing to be activated or deactivated in the third indication information.

The above method provides two different ways of configuring activation or deactivation of multiple carriers and BWPs in one piece of power saving information, and by either way, the activation or deactivation states of multiple carriers and BWPs can be clearly indicated in one piece of power saving information.

By any of the above signaling, the energy saving information can be sent without carrying the energy saving information on the resource for transmitting data to the terminal when transmitting data, so that the terminal can adjust the bandwidth by activating or deactivating BWP in time regardless of whether the data to be transmitted exists, thereby saving power consumption. Meanwhile, the signaling belongs to one of dynamic signaling, and by adopting any one of the dynamic signaling, the time delay for sending the energy-saving information can be reduced, and the correct probability of transmission is improved.

Even when there is no data to be transmitted, the terminal may receive energy saving information sent by the network side device through the first resource, and determine at least one second resource to be activated or deactivated according to the energy saving information. Therefore, when the service changes, the terminal can adjust the bandwidth by activating or deactivating the second resource in time, thereby saving the power consumption of the terminal.

Wherein, one energy saving information can configure indication information of a plurality of carriers and BWPs, and there is no need to separately indicate activation or deactivation of one carrier or BWP through one energy saving information, so that signaling overhead can be greatly reduced.

Detailed Description

Hereinafter, some terms in the embodiments of the present invention are explained to facilitate understanding by those skilled in the art.

(1) The term "resource" in the embodiments of the present invention refers to a carrier or BWP. Data or signaling sent by the network side device to the terminal may be carried on a carrier or BWP.

(2) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

(3) The term "plurality" in the embodiments of the present invention means two or more, and other terms are similar thereto.

The network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

In the embodiment of the invention, the terminal is a device with a wireless communication function, can be deployed on land and comprises an indoor or outdoor, handheld or vehicle-mounted terminal; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiving function, a VR (virtual reality) terminal, an AR (augmented reality) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), etc.; but also UEs in various forms, Mobile Stations (MSs), terminal equipment (terminal devices).

The network side device is a device for providing a wireless communication function for a terminal, and includes but is not limited to: a gbb, an RNC (radio network controller), an NB (node B), a BSC (base station controller), a BTS (base transceiver station), an HNB (e.g., home evolved node B or home node B), a BBU (base band Unit), a TRP (transmission and reception point), a TP (transmission point), a mobile switching center, and the like in 5G. The base station in the embodiment of the present invention may also be a device that provides a wireless communication function for the terminal in other communication systems that may appear in the future.

In the process of the communication between the network-side device and the terminal, the network-side device may send the indication information for activating or deactivating BWP, so that the terminal may adjust the bandwidth and control power consumption according to the indication information for activating or deactivating BWP. However, in the related art, indication information for activating or deactivating BWP is carried in DCI. When there is no data to be transmitted, the network device cannot send DCI to the terminal, so the terminal cannot complete BWP deactivation, and power consumption of the terminal is unnecessarily consumed.

In view of the foregoing problems, embodiments of the present invention provide a method for controlling terminal energy saving, a network side device, and a terminal. The network side equipment indicates the activation or deactivation information of at least one second resource through one or more pieces of energy saving information in at least one first resource. The first resource for carrying the energy saving information may be configured by RRC (Radio resource control, RRC) or may be configured by MAC-CE (Medium access control-control, MAC-CE) or dynamic signaling. The activation or deactivation information of the at least one second resource indicated by the energy saving information may be indicated by a bitmap (bitmap), or may be indicated by identification information of the second resource. The identification information of the second resource may be predefined, and may be RRC configured, MAC-CE configured, or dynamically configured. When there is no data to be transmitted, the network side device may also send energy saving information to the terminal, so that the terminal determines to activate or deactivate the corresponding resource according to the energy saving information, thereby adjusting the bandwidth in time and saving power consumption.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to achieve the above object, an embodiment of the present invention provides a schematic structural diagram of a system for controlling energy saving of a terminal, specifically as shown in fig. 1, where the system includes:

a network side device 100, configured to configure energy saving information in at least one first resource, where the energy saving information includes activation or deactivation information of at least one second resource; wherein the first resource and the second resource are carriers and/or BWPs; and sending the energy-saving information to the terminal so that the terminal determines at least one activated or deactivated second resource according to the energy-saving information, adjusts the bandwidth and saves the power consumption.

The terminal 101 receives energy saving information sent by the network side equipment through at least one first resource; the energy saving information comprises activation or deactivation information of at least one second resource, and the first resource and the second resource are carriers and/or BWPs; and determining the activated or deactivated second resource according to the energy-saving information. Thus, the terminal can rapidly adjust the BWP or the carrier to match the change of the traffic, avoiding waste of power consumption on unnecessary BWP or carrier, and reducing power consumption of the terminal.

In the embodiment of the invention, the network side equipment configures energy-saving information on at least one first resource, wherein the energy-saving information comprises activation or deactivation information of at least one second resource. Wherein the first resource is used for carrying the second resource, and the first resource and the second resource may be a carrier and/or BWP. And the network side equipment sends the energy-saving information to the terminal. Even when there is no data to be transmitted, the network side device may send the energy saving information to the terminal, so that the terminal determines the at least one activated or deactivated second resource according to the energy saving information. When the service changes, the terminal can adjust the bandwidth by activating or deactivating the second resource in time, so that the power consumption of the terminal is saved.

In addition, in the prior art, the activation and deactivation information sent by the network side device can only be used for indicating activation of one carrier, and cannot indicate activation of multiple carriers. If activation and deactivation information of multiple carriers is indicated, multiple DCIs are required to carry BWP information of different carriers, and the overhead of the DCI is increased. In the embodiment of the invention, the activation or deactivation information of a plurality of second resources can be indicated on one first resource, and when one second resource is not required to be activated or deactivated, one piece of energy-saving information is sent through one first resource, so that the signaling overhead can be greatly reduced.

The first resource and the second resource may be the same or different. Specifically, the resource number of the first resource may be the same as or different from the resource number of the second resource, and the number of the first resource may be the same as or different from the number of the second resource.

In the prior art, a network side device sends activation and deactivation information through DCI, which may cause a relatively large time delay. If retransmission exists, the time delay of activation and deactivation of the carrier wave is further increased. In order to reduce the delay, in the embodiment of the present invention, the network side device 100 may send the energy saving information through at least one of the following signaling: energy-saving signaling, dynamic signaling, DCI-based signaling, MAC-CE signaling, and Sequence-based signaling. The signaling belongs to one of dynamic signaling, and the time delay for sending the energy-saving information can be reduced and the correct probability of transmission can be improved by adopting any one of the dynamic signaling. By any of the above signaling, the energy saving information may be sent without carrying the energy saving information on the resource for transmitting data to the terminal 101 when transmitting data, and therefore, the terminal 101 may adjust the bandwidth by activating or deactivating BWP in time regardless of whether there is data to be transmitted, thereby saving power consumption.

The embodiments of the present invention will be described in detail with reference to specific examples.

The network side device 100 may configure energy saving information according to at least one second resource that needs to be activated or deactivated by the terminal 101, and send the energy saving information to the terminal 101. The second resource may be a carrier and/or BWP. In a specific implementation, the network-side device 100 may configure the activation or deactivation information of the carrier and the activation or deactivation information of the BWP independently, or may configure the activation or deactivation information of the carrier and the BWP in combination. The terminal 101 device receives the energy saving information sent by the network side device 100, and determines the activated or deactivated second resource according to the energy saving information.

Which will be separately described below.

The activation or deactivation information of the carrier and the activation or deactivation information of the BWP are configured independently.

(1) Activation or deactivation information for individually configured carriers

The activation of the carrier, that is, the network side device 100 and the terminal 101 may perform data transceiving, signaling transceiving, and reference signal transceiving on the activated carrier. The carriers are deactivated, that is, the network side device 100 and the terminal 101 do not perform data transmission and reception, do not perform signaling transmission and reception, and do not perform reference signal transmission and reception on the deactivated carriers.

The network side device 100 may configure, in the energy saving information, first indication information for indicating that at least one carrier is in an activated or deactivated state. For example, K bits are configured in the power saving information to indicate activation or deactivation of carriers. Specifically, the network-side device 100 may configure the first indication information in at least one of the following ways.

The first mode is as follows: the network side device 100 may put the number of carriers that need to be activated into the first indication information. The terminal 101 receives the energy saving information sent by the network side device 100, obtains the number of the carriers needing to be activated in the first indication information, and determines the activated carriers according to a preset activation sequence. For example, K bits, i.e., 2, are configured in the power saving information^KWhich is used to indicate the number of carriers, or number, that need to be activated. The number of carriers that need to be activated is less than or equal to the maximum number of carriers supported by the network side device 100 or the terminal 101.

In some embodiments, the network side device 100 or the terminal 101 may pre-define the activation sequence of the carriers, and the activation sequence is uniform between the network side device 100 and the terminal 101. For example, the activation order of the carriers may be primary carrier and secondary carrier The carrier with the closest wave number, etc. If one carrier needs to be activated, i.e. 2^KAnd 1, the number of the activated carrier is the number of the main carrier. The network side device 100 sets the number 1 of carriers that need to be activated in the first indication information, and sends the energy saving information to the terminal 101. The terminal 101 receives the energy saving information, and if it is known that the number of carriers to be activated is 1, activates the primary carrier according to the preset activation sequence of the carriers. If two carriers need to be activated, i.e. 2^KAnd 2, the number of the activated carrier is the number of the main carrier and the carrier nearest to the main carrier. The network side device 100 sets the number 2 of carriers that need to be activated in the first indication information, and sends the energy saving information to the terminal 101. The terminal 101 receives the energy saving information, and knows that the number of the carriers to be activated is 2, then activates the main carrier and the carrier closest to the main carrier in number according to the preset activation sequence of the carriers. And so on, and will not be described in detail.

In other embodiments, the activation sequence of the carriers may be RRC configured, and the device 100 and the terminal 101 are unified on the network side. For example, the activation order of RRC configured carriers is a first carrier number, a second carrier number, and so on. If one carrier needs to be activated, i.e. 2 ^KAnd 1, the number of the activated carrier is the first carrier number. The network side device 100 sets the number 1 of carriers that need to be activated in the first indication information, and sends the energy saving information to the terminal 101. The terminal 101 receives the energy saving information, and if it is known that the number of carriers to be activated is 1, activates the first carrier according to the preset activation sequence of the carriers. If two carriers are activated, the number of the activated carrier is { first carrier number, second carrier number }, where the first carrier number and the second carrier number may be positive integers greater than or equal to zero. The network side device 100 sets the number 2 of carriers that need to be activated in the first indication information, and sends the energy saving information to the terminal 101. The terminal 101 receives the energy saving information, and when it is known that the number of carriers to be activated is 2, activates the first carrier and the second carrier according to a preset activation sequence of the carriers.

The second mode is as follows: the network side device 100 determines carrier identification information corresponding to a carrier set to which a carrier that needs to be activated or deactivated belongs according to a first corresponding relationship between the carrier set and the carrier identification information, and places the determined carrier identification information in first indication information, where the carrier set includes a number of a carrier group and a state of the carrier group, and the carrier group includes at least one carrier. The terminal 101 receives energy saving information sent by the network side device 100, determines a carrier set corresponding to carrier identification information in the first indication information according to a first corresponding relationship between the carrier set and the carrier identification information, and determines an activated or deactivated carrier according to the carrier set.

For example, K bits, i.e., 2, are configured in the power saving information^KThe carrier identification information is used for indicating the carrier identification information corresponding to the carrier set to which the carrier needing to be activated or deactivated belongs. The carrier set and the carrier identification information corresponding to the carrier set, that is, the first corresponding relationship, may be predefined by the network side device 100 or the terminal 101, may be configured by RRC, may be configured by MAC-CE, and may be configured by dynamic signaling, that is, may be configured statically, semi-statically, and dynamically. And the carrier set and its corresponding carrier identification information are unified at the network side device 100 and the terminal 101. Illustratively, when K is 2, the first carrier set may be { CC1 activated, CC2 activated, CC3 deactivated, and CC4 deactivated }, where CC1, CC2, CC3, and CC4 are numbers of carrier groups, and each carrier group includes at least one carrier. "activate" and "deactivate" are the states of the carrier group. The second set of carriers may be { CC1 active, CC2 active, CC3 active, CC4 active }. The carrier identification information corresponding to the first carrier set is "00", and the carrier identification information corresponding to the second carrier set is "11". If the network side device 100 puts the carrier identification information "00" in the first indication information, it sends the energy saving information to the terminal 101. The terminal 101 receives the energy saving information, determines a carrier set corresponding to the carrier identification information "00" as a first carrier set according to a first corresponding relationship between the carrier set and the carrier identification information, determines carriers to be activated as carriers in a CC1 carrier group and a CC2 carrier group according to the first carrier set, and determines carriers to be deactivated as carriers in a CC3 carrier group and a CC4 carrier group. If the network side device 100 places the carrier identification information "11" in In the first instruction information, energy saving information is transmitted to the terminal 101. The terminal 101 receives the energy saving information, determines the carrier set corresponding to the carrier identification information "11" as the second carrier set according to the first corresponding relationship between the carrier set and the carrier identification information, and determines the carriers to be activated as carriers in a CC1 carrier group, a CC2 carrier group, a CC3 carrier group and a CC4 carrier group according to the second carrier set.

The third mode is as follows: the network side device 100 determines a bit corresponding to the carrier to be activated or deactivated according to the second corresponding relationship between the first bitmap bit and the carrier, generates a first bitmap, and places the generated first bitmap in the first indication information, wherein a value on the bit is used for indicating the activation or deactivation of the corresponding carrier. The terminal 101 receives the energy saving information sent by the network side device 100, and determines the activated or deactivated carrier according to the second corresponding relationship between the first bitmap bit and the carrier and the first bitmap in the first indication information.

For example, K bits are configured in the energy saving information, and the K bits represent the first bitmap of carrier activation or deactivation. The K-bit configuration is less than or equal to the maximum number of carriers supported by the terminal 101. Illustratively, deactivation may be represented by 0 and activation may be represented by 1 in the first bitmap. The second corresponding relationship between each bitmap bit in the first bitmap and the carrier may be predefined by the network side device 100 or the terminal 101, may be configured by RRC, may be configured by MAC-CE, and may be configured by dynamic signaling. And the second correspondence is unified between the network-side device 100 and the terminal 101. For example, a first Bitmap bit in the first Bitmap corresponds to the first carrier, and a second Bitmap bit in the Bitmap corresponds to the second carrier. If the network side device 100 configures the first Bitmap bit in the Bitmap to be "0" and the second Bitmap bit to be "1", the energy saving information is sent to the terminal 101. The terminal 101 receives the energy saving information, and determines that the first bitmap bit "0" corresponds to the first carrier and the second bitmap bit "1" corresponds to the second carrier according to the second corresponding relationship between each bitmap bit in the first bitmap and the carrier, so that it can be determined that the carrier to be deactivated is the first carrier and the carrier to be activated is the second carrier.

In the above embodiment, one piece of energy saving information may be configured with indication information of multiple carriers, and there is no need to separately indicate activation or deactivation of one carrier through one piece of energy saving information, so that signaling overhead may be greatly reduced.

(2) Configuring activation or deactivation information of BWP individually

The BWP activation means that the network-side device 100 and the terminal 101 can perform data transceiving, signaling transceiving, and reference signal transceiving on the activated BWP. The BWP is deactivated, that is, the network-side device 100 and the terminal 101 do not perform data transmission and reception, do not perform signaling transmission and reception, and do not perform reference signal transmission and reception on the deactivated BWP.

The network-side device 100 may configure second indication information indicating that at least one BWP is in an activated or deactivated state in the power saving information. For example, an L bit is configured in the power saving information to indicate activation or deactivation of BWP. Specifically, the network-side device 100 may configure the second indication information in at least one of the following ways.

The first mode is as follows: the network-side device 100 may place the number of BWPs that need to be activated in the second indication information. The terminal 101 receives the energy saving information sent by the network-side device 100, obtains the number of BWPs required to be activated in the second indication information, and determines the BWPs required to be activated according to a preset activation sequence. For example, L bits are configured in the power saving information to indicate the number of BWPs that need to be activated.

In some embodiments, the activation sequence of BWP may be predefined by the network side device 100 or the terminal 101, may be RRC configured, may be MAC-CE configured, and may be dynamically signaled. I.e. the order of activation of BWPs may be statically configured, semi-statically configured or dynamically configured. And the activation sequence is uniform between the network side device 100 and the terminal 101.

For example, the activation sequence of 4 BWPs may be configured as { BWP0, BWP1, BWP2, BWP3}, where "00" indicates simultaneous activation of 1 BWP, "01" indicates simultaneous activation of 2 BWPs, "10" indicates simultaneous activation of 3 BWPs, and "11" indicates simultaneous activation of 4 BWPs. If the network side device 100 puts "00" in the second indication information, it sends the energy saving information to the terminal 101. The terminal 101 receives the power saving information, and knows that the number of BWPs that need to be activated is 1, and then activates BWPs 0 according to the preset activation sequence of BWPs. If the network side device 100 puts "01" in the second indication information, it sends the energy saving information to the terminal 101. The terminal 101 receives the power saving information, and knows that the number of BWPs that need to be activated is 2, and then activates BWP0 and BWP1 according to the preset activation sequence of BWPs. If the network-side device 100 places "10" in the second indication information, it sends the energy saving information to the terminal 101. The terminal 101 receives the power saving information, and knows that the number of BWPs that need to be activated is 3, and then activates BWP0, BWP1, and BWP2 according to the preset activation sequence of BWPs. If the network-side device 100 places "11" in the second indication information, it sends the energy saving information to the terminal 101. The terminal 101 receives the power saving information, and knows that the number of BWPs that need to be activated is 4, and then activates BWP0, BWP1, BWP2 and BWP3 according to the preset activation sequence of BWPs.

The second mode is as follows: the network-side device 100 determines, according to the third corresponding relationship between the BWP set and the BWP identification information, BWP identification information corresponding to a BWP set to which the BWP that needs to be activated or deactivated belongs, and places the determined BWP identification information in the second indication information, where the BWP set includes the number of the BWP group and the state of the BWP group, and the BWP group includes at least one BWP. The terminal 101 receives the energy saving information sent by the network-side device 100, determines, according to the third correspondence between the BWP set and the BWP identification information, the BWP set corresponding to the BWP identification information in the second indication information, and determines the activated or deactivated BWP according to the BWP set.

For example, L bits, i.e., 2, are configured in the power saving information^LThe third mapping relationship is used for indicating BWP identification information corresponding to the BWP needing to be activated or deactivated or the BWP set to which the BWP needing to be activated or deactivated belongs. The third corresponding relationship may be predefined by the network side device 100 or the terminal 101, may be configured by RRC, may be configured by MAC-CE, and may be configured by dynamic signaling, that is, may be static or semi-staticDynamic, dynamically configured. And the third correspondence is unified between the network-side device 100 and the terminal 101.

In some embodiments, if the total number of activated or deactivated BWPs is greater than or equal to 1, the activated or deactivated BWP number may represent the number of at least one activated BWP. For example, 4 BWPs { BWP0, BWP1, BWP2, BWP3}, while activating only 1 BWP, 00 means activating BWP1, 01 means activating BWP1, 10 means activating BWP2, and 11 means activating BWP 3.

In other embodiments, when L ═ 2, the first BWP set may be { BWP0 activated, BWP1 deactivated, BWP2 deactivated, BWP3 deactivated }, where BWP0, BWP1, BWP2, BWP3 are numbers of BWP groups. "activate" and "deactivate" are the states of the BWP group. The second set of BWPs may be { BWP0 activated, BWP1 activated, BWP2 deactivated, BWP3 deactivated }. The BWP identification information corresponding to the first BWP set is "00", and the BWP identification information corresponding to the second BWP set is "01". If the network-side device 100 places the BWP identification information "00" in the first indication information, it sends power saving information to the terminal 101. The terminal 101 receives the energy saving information, determines the BWP set corresponding to the BWP identification information "00" as the first BWP set according to the first corresponding relationship between the BWP set and the BWP identification information, determines the BWP to be activated as the BWP in BWP0 and determines the BWP to be deactivated as the BWP in BWP1, BWP2 and BWP 3. If the network-side device 100 places the BWP identification information "01" in the first indication information, it sends power saving information to the terminal 101. The terminal 101 receives the energy saving information sent by the network-side device 100, determines, according to the first correspondence between the BWP set and the BWP identification information, that the BWP set corresponding to the BWP identification information "01" is the second BWP set, determines, according to the second BWP set, that the BWP to be activated is the BWP in BWP1 and BWP2, and determines the BWP to be deactivated is the BWP in BWP3 and BWP 4.

The third mode is as follows: the network side device 100 determines, according to a fourth corresponding relationship between the second bitmap bit and the BWP, a bit corresponding to the BWP that needs to be activated or deactivated and generates a second bitmap, and places the generated second bitmap in the second indication information, where a value on the bit is used to indicate the corresponding BWP activation or deactivation. The terminal 101 receives the energy saving information sent by the network side device 100, and determines the activated or deactivated BWP according to the fourth corresponding relationship between the second bitmap bit and the BWP and the second bitmap in the second indication information.

For example, L bits are configured in the power saving information, and the L bits indicate a second bitmap for BWP activation or deactivation. The L-bit configuration is less than or equal to the maximum number of BWPs supported by the terminal 101. Illustratively, deactivation may be represented by 0 and activation may be represented by 1 in the first bitmap. The fourth corresponding relationship between each bitmap bit in the second bitmap and the BWP may be predefined by the network side device 100 or the terminal 101, may be configured by RRC, may be configured by MAC-CE, and may be configured by dynamic signaling. And the fourth correspondence is unified between the network-side device 100 and the terminal 101. If the first bitmap bit in the second bitmap corresponds to the first BWP, the second bitmap bit in the second bitmap corresponds to the second BWP. If the network side device 100 configures the first bitmap bit in the second bitmap to be "0" and the second bitmap bit is configured to be "1", the energy saving information is sent to the terminal 101. The terminal 101 receives the energy saving information, and determines that the first bitmap bit "0" corresponds to the first BWP and the second bitmap bit "1" corresponds to the second BWP according to the fourth corresponding relationship between each bitmap bit in the bitmap and the BWP, so that it can be determined that the BWP to be deactivated is the first BWP and the BWP to be activated is the second BWP.

In the above embodiment, one piece of power saving information may be configured with indication information of a plurality of BWPs, without separately indicating activation or deactivation of one BWP by one piece of power saving information, so that signaling overhead may be greatly reduced.

(3) Simultaneous configuration of activation or deactivation information of carrier and activation or deactivation information of BWP

The network-side device 100 may configure, in the energy saving information, first indication information indicating that at least one carrier is in an activated or deactivated state and second indication information indicating that at least one BWP is in an activated or deactivated state, respectively. The network-side device 100 may configure the activation or deactivation information of the carrier and the activation or deactivation information of the BWP in the energy saving information respectively in any manner described above. The terminal 101 receives the energy saving information of the network-side device 100, and may determine the carrier or BWP that needs to be activated or deactivated by referring to any one of the above manners. And will not be described in detail herein.

And secondly, combining the activation or deactivation information of the configuration carrier and the BWP.

The network-side device 100 may configure, in the power saving information, third indication information for indicating that at least one BWP on at least one carrier is in an activated or deactivated state. For example, M bits are configured in the power saving information to indicate activation or deactivation of BWP on the carrier. Specifically, the network-side device 100 may configure the third indication information in at least one of the following ways.

The first mode is as follows: the network-side device 100 places the carrier identification information corresponding to the carrier that needs to be activated or deactivated and the BWP identification information corresponding to the BWP that needs to be activated or deactivated in the third indication information. The terminal 101 receives the energy saving information sent by the network-side device 100, and may determine the BWP on the activated or deactivated carrier according to the carrier identification information and the BWP identification information in the third indication information. Wherein the carrier identification information may be an index of a number of the carrier, and the BWP identification information may be an index of a number of the BWP.

Specifically, the correspondence between the carrier and the carrier identification information and the correspondence between the BWP and the BWP identification information may be predefined by the network side device 100 or the terminal 101, may be configured by RRC, may be configured by MAC-CE, and may be configured by dynamic signaling, that is, may be configured statically, semi-statically, and dynamically. And the third correspondence is unified between the network-side device 100 and the terminal 101.

In an alternative embodiment, the combined identification information may be used to identify BWP on the carrier that needs to be activated. For example, the network-side device 100 may place the combined identification information "00" in the third indication information, where "00" may represent BWP0 on the activated carrier CC 1. The network-side device 100 may place the combined identification information "01" in the third indication information, and "01" may represent BWP1 on the activated carrier CC 1.

In another optional embodiment, each activated or deactivated carrier may configure an activated or deactivated BWP, where the activated or deactivated BWP of each activated or deactivated carrier indicates a mapping of at least one rule, where the rule may indicate at least one activated or deactivated BWP of at least one activated or deactivated carrier, and specifically, the configured activated or deactivated BWP may be that all activated or deactivated carriers adopt the same BWP configuration; BWP may be independently configured per activated or deactivated carrier, the BWP indicating BWP numbers of all activated or deactivated carriers; for example, the BWP number may represent an index to the number of a group of activated or deactivated BWPs.

TABLE 1

As shown in table 1, when CC1 corresponds to "0", BWP0 on CC1 is activated, when CC1 corresponds to "3", BWP2 on CC1 is activated, and when CC1 to CC4 all correspond to "0", BWP0 on CC1 to CC4 is activated. The "- -" in table 1 indicates that there is no corresponding activation configuration.

Other specific implementation manners may be performed with reference to the activation or deactivation information of the separately configured carrier or the activation or deactivation information of the separately configured carrier, which is not described herein again.

The second way is: the network-side device 100 places the number of carriers that need to be activated and BWP identification information corresponding to the BWPs that need to be activated or deactivated in the third indication information. The terminal 101 determines the BWP on the activated carrier according to the preset activation sequence based on the BWP identification information and the number of carriers that need to be activated in the third indication information. Specifically, the number of the carrier corresponding to the number of the carriers and the number corresponding to the BWP may be predefined, configured by RRC, configured by MAC-CE, and configured by dynamic signaling.

In an optional embodiment, if the number of activated or deactivated carriers indicated by the energy saving information is 1, it indicates that the number of activated or deactivated BWPs on the activated or deactivated carriers is the number of activated or deactivated BWPs indicated by the energy saving information. For example, CC1 is active, BWP number indicates BWP1 is active, and power saving information indicates BWP1 is active on CC 1.

In another alternative embodiment, M bits of third indication information are configured in the power saving information. If M is 2, 00 indicates that two carriers are activated, that is, the number of activated or deactivated carriers indicated by the power saving information is 2, the numbers of the two carriers are predefined as CC1 and CC2, the number of BWP of the two activated carriers is predefined as BWP0, 01 indicates that 3 carriers are activated, the numbers of the three carriers are predefined as CC1, CC2 and CC3, the number of BWP of the three activated carriers is BWP1, and the bandwidth of BWP1 may be smaller than, equal to, or larger than BWP 0.

For example, the activated or deactivated BWP of each activated or deactivated carrier configuration may be that all activated or deactivated carriers adopt the same BWP configuration; BWP may be configured independently for each activated or deactivated carrier. As shown in table 2, different BWPs are respectively configured for the three carriers CC1, CC2, and CC3, which are BWP1, BWP2, and BWP 3.

TABLE 2

The above embodiments provide two different ways of determining activated or deactivated carriers and BWPs when indication information for activating or deactivating multiple carriers and BWPs is configured in a piece of energy saving information in a combined manner, and both the activated or deactivated carriers and BWPs can be determined accurately. Wherein, one energy saving information can configure indication information of a plurality of carriers and BWPs, and there is no need to separately indicate activation or deactivation of one carrier or BWP through one energy saving information, so that signaling overhead can be greatly reduced.

The process of the interaction between the network side device 100 and the terminal 101 is shown in fig. 2, and includes the following steps:

step S201, the network side device configures energy saving information in at least one first resource.

The process of configuring the energy saving information by the network side device has been described in detail above, and is not described herein again.

Step S202, the network side equipment sends energy-saving information to the terminal.

The network side device 100 transmits the energy saving information to the terminal 101 after the at least one first resource configuration energy saving information. The energy saving information may be carried on a dynamic signaling, an energy saving signal, or an existing DCI, and the energy saving signal may carry the configuration of the energy saving information of the terminal 101. And indicating the energy-saving information by increasing the bit field or indicating the energy-saving information by redefining the bit field according to the existing DCI.

The energy saving information may configure a transmission cycle different from that of an energy saving signal carrying other energy saving information, and the transmission parameter, for example, other energy saving information, may be, the network side device 100 configures at least one of energy saving information indicating the terminal 101, including whether to wake up to monitor a PDCCH, whether to not monitor the PDCCH while sleeping, whether to monitor F PDCCH time units, whether to skip monitoring G PDCCH time units, whether to switch BWP, whether to activate or deactivate a carrier, whether to configure a dormant scell, whether to configure a DRX parameter set, whether to configure PDCCH decoding energy saving information, whether to configure an RRM energy saving function, whether to trigger reference signal transmission and/or related measurement information reporting.

The first dynamic signaling of the energy saving information indicates that a bearer in a first time window activates or deactivates a carrier and/or activates or deactivates BWP information, and a time interval of the first time window may be predefined, may be RRC configured, may be MAC-CE configured, may be configured by dynamic signaling, may be the same as or different from the first dynamic signaling of the bearer activating or deactivating a carrier and/or activating or deactivating BWP information.

During the period of configuring the energy saving information by the MAC-CE signaling, the first dynamic signaling is configured to also indicate the activation or deactivation of the carrier, and if the information of the activation or deactivation of the carrier indicated by the MAC-CE signaling and the first dynamic signaling is different, the terminal 101 may select one piece of information indicating the activation or deactivation of the carrier. Specifically, it may be predefined, for example, when receiving two indications, the terminal 101 may activate or deactivate the indication carrier receiving the signaling closest to the receiving time; the carrier may be activated or deactivated as indicated by the first dynamic signaling; the carrier can be activated or deactivated according to the indication of the MAC-CE; one signaling indication may be randomly selected.

Step S203, the terminal determines the activated or deactivated second resource according to the energy saving information.

The process of determining, by the terminal, the activated or deactivated second resource according to the energy saving information is described in detail above, and is not described herein again.

Step S204, the network side equipment and the terminal communicate on the activated second resource.

After the network-side device 100 sends the energy-saving information to the terminal 101, the network-side device 100 and the terminal 101 transmit and receive data, signaling, and reference signals on the configured activated carrier and/or activated BWP. The signaling may be L1 signaling, L2 signaling, RRC signaling, and the reference signal may be a DL reference signal or a UL reference signal. The DL reference signal may be a CSI-RS, may be an SSB, and the UL reference signal may be an SRS.
