Description

Communication method and communication device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and a communication device.

Background

As wireless services are continuously increased and networks are gradually complicated, so that the energy consumption of equipment is continuously increased, and the high energy consumption of a base station becomes one of the main reasons for the high operation cost (operating expense, OPEX) of operators, so that energy conservation and consumption reduction become urgent demands of operators. Currently, the network energy-saving scheme can be designed mainly from three angles of time domain, frequency domain and space domain. For example, in the time domain, network power savings may be achieved by symbol off, remaining minimum system message (remaining minimum system information, RMSI) broadcast period adjustment, symbol or slot aggregation, etc. In the frequency domain, network power saving can be achieved by timing carrier off, etc. In the space domain, network energy conservation can be realized through radio frequency channel turn-off and the like.

Generally, after the base station enters the energy saving state, a User Equipment (UE) needs to be informed, so that the UE can make corresponding adjustment in a subsequent operation, for example, when the network is in a light load or no load state, the base station can reduce the number of times of sending the RMSI by increasing the RMSI broadcast period, thereby achieving the purpose of energy saving of the base station. For the terminal device, the terminal device may calculate a frame number of a Paging Frame (PF) and a Paging Occasion (PO) index value in the PF according to the self identity, so as to receive the energy saving indication from the base station on the corresponding PO, but different UEs may have different POs. Therefore, when a plurality of UEs are accessed in the serving cell, if the base station needs to inform all UEs in the serving cell of the network energy-saving policy, the network energy-saving policy needs to be repeatedly sent on the POs of all the UEs, which results in large signaling overhead and large energy consumption of the base station.

It should be noted that these explanations are for easier understanding of the embodiments of the present application, and should not be construed as limiting the scope of protection claimed by the present application.

1. Short message (short message)

The short message is carried in downlink control information (downlink control information, DCI) and transmitted on a physical downlink control channel (physical downlink control channel, PDCCH). The short message contains 8 bits, and the following table gives a definition of each Bit, where Bit 1 is the most significant Bit.

2、DCI format 1_0

The DCI format carrying the short message is DCI format 1_0, which is scrambled with a paging radio network temporary identifier (paging radio network temporary identifier, P-RNTI), and consists of the following fields:

(1) short message indication (short message indicator) field: indicating the content type in the paging DCI, wherein '01' indicates scheduling information of paging messages only; "10" means only short message; "11" indicates that both the scheduling information and the short message of the paging message exist; "00" is a reserved bit (i.e., the value is not used).

(2) short message field: when the DCI contains only scheduling information of a paging message (short message indication value is 01) with 8 bits, this field is reserved.

(3) A frequency domain resource allocation (frequency domain resource assignment, FDRA) field, a time domain resource allocation (time domain resource assignment, TDRA) field, a virtual resource block (virtual resource block, VRB) to physical resource block (physical resource block, PRB) mapping (VRB-to-PRB mapping) field, a modulation coding scheme (modulation and coding scheme, MCS) field, a transport block scaling (transport block scaling, TB scaling) field, which are reserved when the DCI contains only a short message (short message indicates a value of 10).

(4) Reserved bits, i.e. bits that are not used temporarily.

3. Search space

The search space represents candidate resource locations for the transmission control channel. The network configures a search space for the UE, including a common search space (common search space, CSS) and possibly a UE-specific search space (UE-specific search space, USS). The resources in the network selection search space send control information to the UE and scramble a cyclic redundancy code (cyclic redundancy code, CRC) of the control information using the corresponding RNTI. The UE monitors the control channel on the search space configured by the network and considers the reception to be successful if the control information on the control channel can be correctly decoded using the corresponding RNTI.

4. Paging frame

One paging cycle includes a plurality of system frames, and only some of the system frames have Paging Occasions (POs), and a paging message may be transmitted, wherein the frame with the paging occasions is called a paging frame.

It should be noted that, as wireless services continue to increase, networks are gradually complicated, so that energy consumption of devices is continuously increased, and high energy consumption of a base station becomes one of main reasons for high operating costs (operating expense, OPEX) of operators, so energy saving and consumption reduction become urgent demands of operators. Currently, the network energy-saving scheme can be designed mainly from three angles of time domain, frequency domain and space domain. For example, in the time domain, network power savings may be achieved by symbol off, remaining minimum system message (remaining minimum system information, RMSI) broadcast period adjustment, paging frame number adjustment, symbol or slot aggregation, etc. In the frequency domain, network power saving can be achieved by timing carrier off, etc. In the space domain, network energy conservation can be realized through radio frequency channel turn-off and the like.

Generally, after the base station enters the energy saving state, a User Equipment (UE) needs to be informed, so that the UE can make corresponding adjustment in a subsequent operation, for example, when the network is in a light load or no load state, the base station can reduce the number of times of sending the RMSI by increasing the RMSI broadcast period, thereby achieving the purpose of energy saving of the base station. At this time, the base station needs to inform the UE of the updated RMSI broadcast period, so that the UE can adjust the period of listening to the RMSI accordingly. Specifically, the base station first transmits a short message with the most significant Bit 1 set to 1 in one system message update period to inform the UE that the system message is changed, and then transmits an updated system message in a second system message update period, where the updated system message includes an updated RMSI broadcast period. However, in this way, the base station needs to send the network energy-saving indication message to the UE at least twice in two update periods, so that the processing time is long, the signaling overhead is large, the base station cannot enter the energy-saving state quickly, and the energy consumption of the base station is increased.

Based on the above, the application provides a communication method, which can reduce the power consumption of the access network equipment in the process of sending the network energy-saving indication and improve the sending efficiency of the network energy-saving indication.

The following describes the communication method and the communication device provided by the application in detail:

referring to fig. 2, fig. 2 is a schematic flow chart of a communication method according to an embodiment of the application. As shown in fig. 2, the communication method includes the following steps S201 to S202:

s201, the terminal equipment receives first indication information from the access network equipment.

In some possible embodiments, when the access network device determines to enter the power saving state, or when the access network device determines to employ the power saving policy, the access network device may send first indication information to the terminal device, and accordingly, the terminal device receives the first indication information from the access network device. The first indication information comprises energy saving strategy indication information and/or energy saving state indication information. Generally, the energy saving policy indication information is used to indicate an energy saving policy of the access network device, and the energy saving state indication information is used to indicate that the access network device is in an energy saving state. The first indication information may be carried in a short message (short message), specifically, the first indication information may be carried in at least one bit from the 4 th bit to the 8 th bit in the short message, that is, the first indication information may be carried in 1 or more reserved bits in the short message. Wherein, the short message is carried in the short message field of DCI.

For convenience of understanding, the following embodiments of the present application mainly take the example that the first indication information is carried in the 4 th Bit to the 8 th Bit in the short message as an example, that is, the length of the first indication information is 5 bits, or understand that all the reserved bits (i.e., bits 4 to Bit 8) in the short message are used to indicate the energy saving policy adopted by the access network device and/or indicate that the access network device is in the energy saving state.

Wherein the energy-saving strategy indication information is used for indicating the energy-saving strategy of the access network equipment, comprising the following steps: the power saving policy indication information is used to indicate one or more power saving policies of the access network device. Wherein the energy saving policy of the access network device comprises one or more of the following: dynamic energy saving, static energy saving, semi-static energy saving, SSB set change, paging frame number change in paging cycle, auxiliary uplink (supplementary uplink, SUL) carrier turn-off, symbol turn-off, RMSI broadcast cycle adjustment, symbol or slot convergence, timing carrier turn-off (i.e., turning off some designated carriers in a fixed period), radio frequency channel turn-off, etc., without limitation herein.

It should be noted that, the above static energy saving can be understood as that the base station will set the energy saving start time and the energy saving end time, that is, the base station will start energy saving in a fixed period of time, and thus is considered as static. The dynamic energy saving means that the base station can decide whether to start energy saving and stop energy saving at any time according to the current network state, so that the method is more flexible. The semi-static energy saving is between static energy saving and dynamic energy saving, for example, the base station can decide to enter the energy saving state according to the current network state, and set a time period for the energy saving to be effective, etc. The above SSB set change may be understood as requiring that the UE be informed of the updated set of available SSBs when the base station turns off some beams due to entering the power saving state. The above-mentioned paging frame number change in the paging cycle may be understood as that when the base station decreases the number of paging frames included in one paging cycle due to entering the power saving state, the UE needs to be informed of the remaining available number of paging frames. The SUL carrier refers to an auxiliary uplink carrier, and in general, the base station may configure a SUL for the UE in addition to a Normal Uplink (NUL) for the UE to expand coverage. Wherein when the base station enters a power saving state, the SUL carrier may be selected to be turned off and only NUL may be used.

The following describes in detail the case where the first indication information includes the energy saving policy indication information and/or the energy saving state indication information, respectively.

(1) In one implementation, when the first indication information includes energy saving policy indication information, i.e. the first indication information indicates an energy saving policy adopted by the access network device, one or more bits of reserved bits (i.e. at least one bit from 4 th bit to 8 th bit in the short message) of the short message may be used to indicate an energy saving policy.

For example, taking the length of the first indication information as 5 bits as an example, assuming that each of the 4 th bit to the 8 th bit in the short message is used for indicating one energy saving policy, the 4 th bit can be used for indicating the energy saving policy 1 when the value of the 4 th bit is 1, the 5 th bit can be used for indicating the energy saving policy 2 when the value of the 5 th bit is 1, the 6 th bit can be used for indicating the energy saving policy 3 when the value of the 6 th bit is 1, the 7 th bit can be used for indicating the energy saving policy 4 when the value of the 7 th bit is 1, and the 8 th bit can be used for indicating the energy saving policy 5 when the value of the 8 th bit is 1, wherein the energy saving policies 1 to 5 are different, for example, the energy saving policy 1 is an even numbered SSB switch-off, the energy saving policy 2 indicates that the number of paging frames is reduced to 1/2, the energy saving policy 3 indicates that the SUL is switched off, the RMSI broadcasting period is enlarged by 1 time, the energy saving policy 5 indicates that the radio frequency channel is switched off, and the like, without limitation.

As another example, taking the length of the first indication information as 5 bits as an example, assuming that one or more bits from the 4 th bit to the 8 th bit in the short message are used to indicate a power saving policy, the 4 th bit and the 5 th bit may be used to jointly indicate a power saving mode adopted by the access network device, where the power saving mode may include dynamic power saving, semi-static power saving, etc., for example, when the values of the 4 th bit and the 5 th bit are 01, semi-static power saving is represented when the values of the 4 th bit and the 5 th bit are 10, static power saving is represented when the values of the 4 th bit and the 5 th bit are 11, or static power saving is represented when the values of the 4 th bit and the 5 th bit are 01, dynamic power saving is represented when the values of the 4 th bit and the 5 th bit are 10, semi-static power saving is represented when the values of the 4 th bit and the 5 th bit are 11, etc., which is not limited. Wherein, the 6 th bit value is 1, which can indicate the change of the SSB set, the 7 th bit value is 1, which can indicate the number of paging frames in the paging cycle to be halved, and the 8 th bit value is 1, which can indicate the SUL to be turned off.

(2) In another implementation, when the energy saving policy indication information is used to indicate the energy saving policy of the access network device, the energy saving policy indication information may be specifically an index indicating the energy saving policy. For example, assume that there are energy saving policies 1-7, where energy saving policy 1 may be dynamic energy saving, even numbered SSB off, paging frame number reduced to 1/2, sul off; the energy saving strategy 2 can be dynamic energy saving, the odd numbered SSB is turned off, the number of paging frames is reduced to 1/2, and the SUL is turned off; the energy saving strategy 3 can be semi-static energy saving, even numbered SSB is turned off, the number of paging frames is reduced to 1/4, and NUL is turned off; the energy saving strategy 4 can be semi-static energy saving, the odd numbered SSB is turned off, the paging frame number is reduced to 1/4, and the NUL is turned off; the energy saving strategy 5 can be static energy saving, even numbered SSB is turned off, the number of paging frames is reduced to 1/4, and NUL is turned off; the energy saving strategy 6 can be semi-static energy saving, even numbered SSB is turned off, the number of paging frames is reduced to 1/4, and NUL is turned off; the energy saving strategy 7 is semi-static energy saving, the even numbered SSB is turned off, the paging frame number is reduced to 1/5, and the NUL is turned off. The index value of the energy saving strategy 1 is 0, the index value of the energy saving strategy 2 is 1, the index value of the energy saving strategy 3 is 2, the index value of the energy saving strategy 4 is 3, the index value of the energy saving strategy 5 is 4, the index value of the energy saving strategy 6 is 5, and the index value of the energy saving strategy 7 is 6. Therefore, when the base station decides to adopt the energy saving policy 1, bits 4 to 8 of the short message can be set to 00001, when the base station decides to adopt the energy saving policy 5, bits 4 to 8 of the short message can be set to 00100, and when the base station decides to adopt the energy saving policy 7, bits 4 to 8 of the short message can be set to 00110, which is not exemplified here.

(3) In another implementation, the first indication information may be energy saving state indication information, where the energy saving state indication information may be carried in any one or more bits of reserved bits of the short message (i.e., the 4 th bit to the 8 th bit of the short message). For convenience of understanding, the following description will mainly take an example that the energy-saving state indication information is carried in any one bit from the 4 th bit to the 8 th bit of the short message as an example, for example, the energy-saving state indication information may be carried in the 4 th bit of the short message, where by setting the value of the bit to 1, it may be indicated that the short message carries the energy-saving state indication information, or it may be understood that the access network device may be indicated to enter the energy-saving state. When the first indication information is the energy saving state indication information, the value of the short message indication field in the DCI is set to 10, which indicates that the DCI does not include the scheduling information of the paging message. In addition, the DCI may also carry scheduling information of the energy-saving policy adopted by the access network device. Thus, the access network device may send a medium access control (media access control, MAC) protocol data unit (protocol data unit, PDU) to the terminal device according to the scheduling information, the MAC PDU including the power saving policy therein. Accordingly, the terminal device may receive the MAC PDU carrying the energy saving policy from the access network device according to the scheduling information. Generally, the scheduling information of the power saving policy may be specifically carried in at least one of fields such as FDRA field, TDRA field, VRB-to-PRB mapping field, MCS field, and TB scaling field in DCI. The scheduling information of the energy-saving strategy may specifically include one or more information of a time domain resource, a frequency domain resource, an adopted modulation and coding scheme, and the like where the MAC PDU carrying the energy-saving strategy is located. That is, in this implementation manner, the access network device may use a certain Bit or a plurality of bits in the reserved bits (bits 4 to 8) of the short message to inform the UE that the access network device enters the energy saving state, and inform the UE that the scheduling information of the MAC PDU carrying the specific energy saving policy through the DCI, so that the terminal device may receive the MAC PDU carrying the energy saving policy from the access network device according to the scheduling information. As can be appreciated, the DCI is sent on PDCCH and the MAC PDU is sent on physical downlink shared channel (physical downlink shared channel, PDSCH).

(4) In another implementation, the first indication information may include both energy saving policy indication information and energy saving state indication information, i.e. the first indication information may be used to indicate that the access network device is in an energy saving state and to indicate an energy saving policy of the access network device. In such an implementation, a portion of bits 4 to 8 of the short message may be used to indicate the power saving state of the access network device, and a bit different from the foregoing portion of bits 4 to 8 may be used to indicate the power saving policy of the access network device. For example, the 4 th bit of the 4 th to 8 th bits of the short message may be used to indicate the power saving state of the access network device, and the 5 th to 7 th bits may be used to indicate the power saving policy of the access network device, wherein the remaining 8 th bits remain as reserved bits. For another example, the 4 th bit of the 4 th to 8 th bits of the short message may be used to indicate the power saving state of the access network device, the 5 th to 8 th bits may be used to indicate the power saving policy of the access network device, and the like, without limitation. It should be noted that the number of the substrates,

optionally, in some possible embodiments, the access network device may further send second indication information to the terminal device, and accordingly, the terminal device receives the second indication information from the access network device. The second indication information includes PO indication information or search space indication information. The PO indication information is used for indicating the first PO, and the search space indication information is used for indicating the first search space. Wherein the first PO or the first search space is used for one or more terminal devices to listen to the first indication information, i.e. the first PO may be understood as a common PO and the first search space may be understood as a common search space (common search space, CSS). In the embodiments of the present application, public may also be described as private, without limitation. Thus, the above terminal device receiving the first indication information from the access network device may be understood as: the terminal device receives first indication information from the access network device on the first PO or the first search space. That is, the access network device designates the common PO or CSS, and further sends the short message carrying the first indication information to all UEs in the service area on the common PO or CSS at the same time, so that the number of times of sending the indication can be reduced, thereby reducing the energy consumption of the access network device. This is because in the related art, the terminal device needs to calculate its own listening opportunity according to its own identity, and the listening opportunities of different terminal devices may be different, so in order to enable all UEs in the service area to learn the energy saving state of the access network device, and a specific energy saving policy, the access network device needs to send network energy saving indication to different UEs on different POs multiple times, and needs to send a message to the UE twice in two update periods each time to inform the UE of the network energy saving indication message, which has high power consumption.

It should be noted that the second indication information may be carried in a system message, for example, the system message may be system information block 1 (system information block, SIB 1), SIB2, or the like, which is not limited herein.

It can be appreciated that the above PO indication information is used to indicate that the first PO can be understood as: the PO indication information is used for indicating the time domain position of the first PO. Specifically, the PO indication information includes an index value of a paging frame where the first PO is located, and a PO index value on the paging frame; or, the PO indication information includes an index value of a system frame where the first PO is located and a slot index value or an index range on the system frame.

S202, the terminal equipment and the access network equipment communicate based on the first indication information.

In some possible embodiments, when the terminal device learns that the access network device is in a power saving state and determines a power saving policy of the access network device, communication between the terminal device and the access network device may be performed based on the first indication information. For example, when the first indication information indicates that the power saving policy of the access network device is power saving policy 1 and the power saving policy 1 is SSB with odd number is turned off, the terminal device and the access network device may use SSB with even number to communicate.

It should be noted that, in the related art, the terminal device needs to calculate its own monitoring opportunity according to its own identity, and the monitoring opportunities of different terminal devices may be different, so in order to enable all UEs in the service area to learn the energy saving state of the access network device, and a specific energy saving policy, the access network device needs to send network energy saving indication to different UEs on different POs multiple times, and needs to send a message to the UE twice in two update periods each time to inform the UE of the network energy saving indication message, which has high power consumption. Based on this, the embodiment of the application also provides a communication method, which can reduce the frequency of sending the instruction and reduce the energy consumption of the access network equipment.

Wherein the first PO or the first search space is used for one or more terminal devices to monitor the first indication information, i.e. the first PO may be understood as a common PO and the first search space may be understood as a CSS. In the embodiments of the present application, public may also be described as private, without limitation.

It should be noted that the second indication information may be carried in a system message, for example, the system message may be SIB1, SIB2, or the like, which is not limited herein. It can be appreciated that the above PO indication information is used to indicate that the first PO can be understood as: the PO indication information is used for indicating the time domain position of the first PO. Specifically, the PO indication information includes an index value of a paging frame where the first PO is located, and a PO index value on the paging frame; or, the PO indication information includes an index value of a system frame where the first PO is located and a slot index value or an index range on the system frame.

S302, the terminal equipment receives first indication information from the access network equipment on a first PO or a first search space.

In some possible implementations, the terminal device may receive the first indication information from the access network device on the first PO or the first search space.
