Description

Energy-saving parameter sending method, receiving method and equipment
Technical Field
The invention relates to the technical field of mobile communication, in particular to a method and a device for sending and receiving energy-saving parameters.
Background
In a Physical Downlink Control Channel (PDCCH) of a new air interface (NR) system, a User Equipment (UE) configures up to 3 control resource sets (CORESET) and 10 search spaces on an active bandwidth Part (BWP, bandwidth Part). The CORESET mainly configures the resource position of the PDCCH, including frequency domain resources, a resource mapping mode, the size of resource element group bundling (REG bundle), and the like. The search space set mainly configures a detection period, a detection offset value, a detection time length, aggregation levels, the number of PDCCH candidate sets of each aggregation level, and the like of the search space set. When configuring the search space, the higher layer signaling configures parameters such as its detection period and detection offset value, the type of the search space, and the DCI format to be detected. And the UE detects the PDCCH in different search spaces according to the time domain detection position configured by the high-layer signaling.
In NR, different search spaces may correspond to different search space types and different detection locations. The UE can only perform PDCCH detection according to the detection position configured by the higher layer signaling. However, due to the uncertainty of the time of the data packet, the UE may detect the PDCCH but not the scheduling information in the Downlink Control Information (DCI), and in this case, the UE performs a useless PDCCH detection, which consumes energy.

As described in the background, the terminal may perform useless PDCCH detection resulting in unnecessary power consumption. At present, under the condition of no scheduling data of a certain terminal, if a terminal wants to avoid useless PDCCH detection, one way is to reconfigure configuration information of a search space of the terminal through high-level signaling, but the time delay of the high-level signaling is too large to dynamically adapt to service characteristics. Another way is to instruct the terminal to avoid useless PDCCH detection by means of physical layer signaling. The network side can judge whether data of a certain terminal needs to be scheduled in the next period of time according to the current cache, so that the terminal can be indicated not to need to detect the PDCCH in the next period of time through the physical layer dynamic signaling. In addition, the configuration parameters of the high-level signaling may also affect the energy consumption effect of the terminal, such as scheduling timing, MIMO layer number, and the like, so that the change of the parameters of the terminal may also be indicated through the dynamic signaling, thereby achieving the effect of energy saving.
Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a base station 12. The terminal 11 may also be referred to as a user terminal or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The Base Station 12 may be various Base stations and/or core network elements, wherein the Base stations may be 5G and later-version Base stations (e.g., gNB, 5G NR NB, etc.), or Base stations in other communication systems (e.g., eNB, WLAN access point, or other access points, etc.), wherein the Base Station 12 may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention, only the Base Station in the NR system is taken as an example, but does not limit the specific type of base station.
The base stations 12 may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.
Base station 12 may communicate wirelessly with terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area.

The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to base station 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from base station 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.
It should be noted that the network device according to the embodiment of the present invention may be implemented by the base station (access network node) in fig. 2, or may be implemented by the core network node, or by both the access network node and the core network node.
Referring to fig. 2, a method for sending an energy saving parameter according to an embodiment of the present invention is applied to a base station, and includes:
step 21, transmitting a first DCI format for indicating a power saving parameter of a terminal.
The energy-saving parameter includes a time length K for which the terminal does not detect the PDCCH after receiving the first DCI format, and/or a value range of a high-level configuration parameter of the terminal.
Here, the first DCI format may specifically be DCI format 0_0 and/or DCI format 0_ 1. The time length K in the energy-saving parameter can indicate the time range of the terminal for stopping the PDCCH detection, so that the energy consumption of the terminal caused by the PDCCH detection can be saved. Specifically, the time length K is one of at least one time length candidate value preconfigured in the higher layer signaling, and the time length K is a time slot, a millisecond, a subframe, or a multiple of the first DCI detection period.
The value or value range of the high-level configuration parameter in the energy saving parameter may specifically include at least one of the following parameters: a slot offset value k0 of the PDSCH scheduled by the first DCI format and the first DCI format, a slot offset value k2 of the PUSCH scheduled by the first DCI format and the first DCI format, a number of multiple-input multiple-output (MIMO) layers, a number of antennas, and a Discontinuous Reception (DRX) configuration parameter. For example, the time slot offset value k0 can reduce unnecessary receiving processing and reduce receiving energy consumption when the terminal is scheduled by crossing time slot data. And the DRX configuration parameter is configured to be the discontinuous reception of the terminal so as to reduce the energy consumption of the terminal. Therefore, the parameters can be used for the energy-saving processing of the terminal, so that support can be provided for the terminal to execute the energy-saving processing through the value or the indication of the value range of the parameters, and the energy consumption of the terminal is reduced.
Through the steps, the embodiment of the invention can send the energy-saving parameters to the terminal to provide support for the terminal to execute energy-saving processing, thereby reducing the energy consumption of the terminal.
In step 21, when the base station transmits the first DCI format, the base station may scramble Cyclic Redundancy Check (CRC) information of the first DCI format by using a cell radio network temporary identifier (C-RNTI) or a predefined first RNTI, that is, the CRC information of the first DCI format is scrambled by using the C-RNTI or the predefined first RNTI. Here, the first RNTI is a new RNTI defined in an embodiment of the present invention, and is specifically used for scrambling DCI for transmitting the energy saving signal.
According to at least one embodiment of the present invention, when the CRC information of the first DCI format in step 21 above is scrambled via C-RNTI, the first DCI format may include at least one of the following fields: the terminal comprises a frequency domain resource allocation domain, a frequency domain hopping indication domain, a first information domain and a second information domain, wherein the first information domain is used for indicating the time length K, and the second information domain is used for indicating the value or the value range of the high-level configuration parameters of the terminal. Preferably, the first DCI format may include the first information field and/or the second information field. The frequency domain resource allocation field and/or the frequency domain hopping indication field may be optional fields, and may or may not be included in the first DCI format.
As described above, the DCI format according to the embodiment of the present invention may be DCI format 0_0 and/or DCI format 0_ 1. That is, the embodiment of the present invention multiplexes the existing DCI format to transmit the energy saving parameter. Therefore, when the C-RNTI is used to scramble the first DCI, in order to avoid confusion with values of existing domains in the existing DCI format, the embodiment of the present invention uses values that are not used in the frequency domain resource allocation domain and/or the frequency domain hopping indication domain in the prior art to indicate that the first DCI is the DCI for transmitting the energy saving parameter.
According to at least one embodiment of the present invention, when the first DCI format is DCI format 0_0, the frequency domain resource allocation field is all 1, and the frequency domain hopping indication field is all 0.
When the first DCI format is DCI format 0_ 1:
if the terminal is only configured with the resource allocation type 0, the frequency domain resource allocation domain is all 0;
if the terminal is only configured with the resource allocation type 1 and the high-level signaling is not configured with the frequency domain hopping parameter, the frequency domain resource allocation domain is all 1;
if the terminal is only configured with the resource allocation type 1 and the high-level signaling is configured with the frequency domain hopping parameter, the frequency domain resource allocation domain is all 1, and the frequency domain hopping indication domain is all 0;
If the terminal is configured with the resource allocation type 0 and the resource allocation type 1 and the high-level signaling is not configured with the frequency domain hopping parameter, the frequency domain resource allocation domain is all 0 or all 1;
if the terminal is configured with the resource allocation type 0 and the resource allocation type 1 and the high-level signaling is configured with the frequency domain hopping parameter, the frequency domain resource allocation domain is all 0 or all 1 and the frequency domain hopping indication domain is all 0.
In this way, by taking a specific value of the frequency domain resource allocation field and/or the frequency domain hopping indication field, the first DCI format may be implicitly indicated as an energy saving parameter for indicating the terminal, rather than indicating scheduling information of the terminal.
According to at least one embodiment of the present invention, when CRC information of the first DCI format is scrambled via the first RNTI, it may be directly determined that the first DCI format is a power saving parameter for indicating a terminal, from the scrambled first RNTI used by the first DCI format. At this time, the first DCI format may include a first information field and/or a second information field, where the first information field is used to indicate the time length K, and the second information field is used to indicate a value or a value range of a higher-layer configuration parameter of the terminal.
In addition, in this implementation, the base station may further configure the first RNTI for the terminal through a higher layer signaling, where the higher layer signaling may be an RRC signaling or the like.
In consideration of practical application, the terminal may access one primary cell/primary serving cell and at least one secondary cell/secondary serving cell. In the above application scenario, when the first DCI format in step 21 is sent, the base station may send the first DCI format to the terminal in a primary cell, where the first DCI format may include multiple sets of information fields indicating the energy saving parameters, each set of information field indicating the energy saving parameters corresponds to one cell, the cell may include a primary cell/primary serving cell and/or an auxiliary cell/auxiliary serving cell, and each set of energy saving parameters includes a time length K for which the terminal does not detect a PDCCH in a corresponding cell after receiving the first DCI format, and/or a value range of a high-level configuration parameter of the terminal in the corresponding cell.
In addition, according to at least one embodiment of the present invention, the first information field and/or the second information field at the corresponding position of each cell in the first DCI format indicates the energy saving parameter corresponding to the cell, and the corresponding position of each cell in the first DCI format may be pre-configured by higher layer signaling or predefined by a protocol.
With reference to fig. 3, an embodiment of the present invention further provides a process of a method for receiving an energy saving parameter at a terminal side, where the process includes:
Step 31, a terminal receives a first DCI format sent by a network, where the first DCI format is used to indicate an energy saving parameter of the terminal, and the energy saving parameter includes a time length K for which the terminal does not detect a PDCCH after receiving the first DCI format, and/or a value range of a high-level configuration parameter of the terminal.
Here, the first DCI format may specifically be DCI format 0_0 and/or DCI format 0_ 1. The time length K is one of at least one time length candidate value pre-configured by a higher layer signaling, and the time length K is a multiple of a time slot, a millisecond, a subframe, or the first DCI detection period. The high-layer configuration parameters include at least one of the following parameters: a slot offset value k0 of the PDSCH scheduled by the first DCI format and the first DCI format, a slot offset value k2 of the PUSCH scheduled by the first DCI format and the first DCI format, a number of MIMO layers, a number of antennas, and DRX configuration parameters.
Through the steps, the terminal can obtain the energy-saving parameter from the first DCI format sent by the network, so that support is provided for executing energy-saving processing, the terminal can conveniently execute a process of controlling the energy of the terminal, and the energy consumption of the terminal is reduced.
According to at least one embodiment of the present invention, after the step 31, the method may further include:
and step 32, determining that the first DCI format is scheduling information for indicating a terminal or an energy-saving parameter for indicating the terminal according to a scrambling mode of the CRC information of the first DCI and/or a value of a predetermined field in the first DCI format.
Here, the CRC information of the first DCI format may be scrambled via the C-RNTI or a predefined first RNTI.
As described previously, when CRC information of the first DCI format is scrambled via C-RNTI, the first DCI format includes at least one of the following domains: the terminal comprises a frequency domain resource allocation domain, a frequency domain hopping indication domain, a first information domain and a second information domain, wherein the first information domain is used for indicating the time length K, and the second information domain is used for indicating the value or the value range of the high-level configuration parameters of the terminal. And when the CRC information of the first DCI format is scrambled by the first RNTI, the first DCI format includes a first information field and/or a second information field, where the first information field is used to indicate the time length K, and the second information field is used to indicate a value or a value range of a high-level configuration parameter of the terminal.
According to at least one embodiment of the present invention, when the CRC information of the first DCI format is scrambled by the C-RNTI, in step 32, the terminal may determine that the first DCI format is used to indicate the power saving parameter of the terminal when the first DCI format is DCI format 0_0, the frequency domain resource allocation field is all 1, and the frequency domain hopping indication field is all 0.
According to at least one embodiment of the present invention, when the CRC information of the first DCI format is scrambled via the C-RNTI, in step 32, the terminal may further determine that the first DCI format is used to indicate a power saving parameter of the terminal when any of the following conditions is satisfied:
the first DCI format is DCI format 0_1, and:
the terminal is only configured with a resource allocation type 0, and the frequency domain resource allocation domain is all 0; alternatively, the first and second electrodes may be,
the terminal is only configured with a resource allocation type 1, a high-level signaling is not configured with a frequency domain hopping parameter, and the frequency domain resource allocation domain is all 1; alternatively, the first and second electrodes may be,
the terminal is only configured with a resource allocation type 1, and the high-level signaling is configured with frequency domain hopping parameters, the frequency domain resource allocation domain is all 1, and the frequency domain hopping indication domain is all 0; alternatively, the first and second electrodes may be,
the terminal is configured with a resource allocation type 0 and a resource allocation type 1, the high-level signaling is not configured with a frequency domain hopping parameter, and the frequency domain resource allocation domain is all 0 or all 1; alternatively, the first and second electrodes may be,
The terminal is configured with a resource allocation type 0 and a resource allocation type 1, the high-level signaling is configured with frequency domain hopping parameters, the frequency domain resource allocation domain is all 0 or all 1, and the frequency domain hopping indication domain is all 0.
According to at least one embodiment of the present invention, when the CRC information of the first DCI format is scrambled via the first RNTI, the terminal may directly determine that the first DCI format is DCI indicating the power saving parameter of the terminal in step 32.
And step 33, when the first DCI format is an energy-saving parameter for indicating a terminal, the terminal acquires the energy-saving parameter from the first DCI, and executes corresponding energy-saving processing according to the energy-saving parameter.
Here, when determining that the first DCI format is an energy saving parameter indicating a terminal, the terminal may perform corresponding energy saving processing, such as stopping detecting a PDCCH, performing DRX processing, and the like, on the energy saving parameter acquired from the first DCI, so as to reduce energy consumption of the terminal.
Through the steps, the embodiment of the invention can realize that the terminal carries out energy-saving processing based on the energy-saving parameters in the first DCI format, thereby reducing the energy consumption of the terminal.
In addition, according to at least one embodiment of the present invention, the terminal may further receive the first RNTI configured by the network for the terminal through a higher layer signaling (such as RRC signaling) so as to be used for performing the descrambling processing of the first DCI format in step 32.
In addition, when the terminal according to the embodiment of the present invention may have access to multiple cells simultaneously, for example, when one primary cell/primary serving cell and at least one secondary cell/secondary serving cell are accessed, in step 31, when receiving the first DCI format, the terminal may receive the first DCI format that is sent to the terminal by the network in the primary cell. Here, the first DCI format includes a plurality of sets of information fields indicating the energy-saving parameters, each set of information fields indicating the energy-saving parameters corresponds to a cell, the cell includes a primary cell/primary serving cell and/or a secondary cell/secondary serving cell, and each set of energy-saving parameters includes a time length K for which the terminal does not detect a PDCCH in the corresponding cell after receiving the first DCI format, and/or a value range of a higher-layer configuration parameter of the terminal in the corresponding cell.
Specifically, the first information field and/or the second information field at the corresponding position of each cell in the first DCI format indicates the energy saving parameter corresponding to the cell, and the corresponding position of each cell in the first DCI format is pre-configured by a high layer signaling or predefined by a protocol.
The above describes the flows of the method for transmitting the energy saving parameter at the base station side and the method for receiving the energy saving parameter at the terminal side according to the embodiment of the present invention. To facilitate a better understanding of the above embodiments, the above flow is further illustrated below by way of several examples.
Example one: indicating only serving cells
A network side (specifically, a base station) sends a DCI format 0_0, which is used to indicate a time length and/or a value range of a higher layer configuration parameter for a certain terminal not to detect a PDCCH after receiving the DCI format,
here, the CRC of the DCI format 0_1 is scrambled by the C-RNTI. The DCI format specifically includes a frequency domain resource allocation field, a frequency domain hopping indication field, a first information field, and a second information field. Here, the frequency domain resource allocation fields of the DCI format 0_0 are all set to 1, and the frequency domain hopping indication fields are all set to 0. In addition, there are 4 time candidate sets configured by higher layer signaling that the terminal does not detect PDCCH after detecting the DCI format 0_ 1: 2 slots, 5 slots, 10 slots and 20 slots. The higher layer configuration parameters configured by the higher layer signaling may specifically include: the slot interval (with values of 0 and 1) of the DCI and the PDSCH scheduled by the DCI, and the number of MIMO layers (with values of 2 and 4).
After receiving the DCI format 0_0, the terminal descrambles the DCI format 0_0 via the C-RNTI, obtains that all bits of the frequency domain resource allocation domain are set to 1, and all bits of the frequency domain hopping indication domain are set to 0, so that the terminal can determine that the DCI format 0_0 is used for indicating the energy saving parameter of the terminal.
Assuming that two bits of the first information field of the DCI format are "10", the terminal may determine, according to a preset correspondence, that the value of the first information field indicates the 3 rd (10 slots) of the 4 time candidate sets, that is, indicate that the terminal does not detect the PDCCH in the 10 slots after receiving the DCI format. The corresponding relation between each value of the first information field and the candidate time in the time candidate set can be predefined by a protocol or preconfigured by a network.
Similarly, it is assumed that the second information field of the DCI format includes 1 bit, which is set to be "0", and indicates that the slot interval of the DCI format and the PDSCH scheduled by the DCI format is set to be "0" and the MIMO layer number is set to be "2". Or, the second information field of the DCI format includes 2 bits, and the 2 bits are respectively used to indicate the DCI format and the time slot interval value and the MIMO layer number value of the PDSCH scheduled by the DCI format according to the preset corresponding relationship. For example, the first bit of the 2 bits indicates the slot interval value, and the second bit indicates the MIMO layer number value. When the second information field is set to "10", the slot interval of the DCI format and the PDSCH scheduled by the DCI format may be set to "1" and the number of MIMO layers may be set to "2" respectively.
Example two: indicating multiple secondary cells
It is assumed that the terminal currently accesses one primary cell and two secondary cells. The network side sends a DCI format 0_0 in the primary cell, which is used to indicate the terminal not to detect the time length of the PDCCH and/or the value or value range of the high-level configuration parameter in the primary cell and the secondary cell after receiving the DCI, and the CRC of the DCI format 0_1 is scrambled by the C-RNTI. The DCI format includes 1 frequency domain resource allocation field, 1 frequency domain hopping indication field, 3 first information fields (corresponding to 1 primary cell and 2 secondary cells, respectively), and 3 second information fields (corresponding to 1 primary cell and 2 secondary cells, respectively).
Here, bits of the frequency domain resource allocation field of DCI format 0_0 are all set to 1, and bits of the frequency domain hopping indication field are all set to 0. In addition, the time candidate set in which the terminal does not detect the PDCCH after detecting the DCI format on the primary cell and the secondary cell is configured by the higher layer signaling is 4: 2 slots, 5 slots, 10 slots and 20 slots. The high-level configuration parameters of the primary cell and the secondary cell configured by the high-level signaling comprise: the slot interval (with values of 0 and 1) and the number of MIMO layers (with values of 2 and 4) of the DCI and its scheduled PDSCH.
Assuming that the 1 st first information field of the DCI format includes 2 bits, whose value is "10", the terminal is instructed not to detect the PDCCH in 10 slots after receiving the DCI on the primary cell. The 1 st second information field of the DCI format includes 1 bit, whose value is "0", and indicates that the slot interval between the DCI on the primary cell and the PDSCH scheduled by the terminal is set to be the first value "0" and the number of MIMO layers is set to be the first value "2". Or, the first and second information fields of the DCI format are "10", which indicates that the slot interval of the DCI and the scheduled PDSCH thereof on the primary cell of the terminal is set to a second value "1" and the number of MIMO layers is set to a first value "2".
The 2 nd first information field of the DCI format includes 2 bits, whose value is "01", indicating that the terminal does not detect the PDCCH in 5 time slots after receiving the DCI on the first secondary cell. The 2 nd second information field of the DCI format includes 1 bit, whose value is "0", and indicates that the slot interval between the DCI on the first auxiliary cell and the PDSCH scheduled by the terminal is set to be a first value "0" and the number of MIMO layers is set to be a first value "2". Or, the 2 nd second information field of the DCI format includes 2 bits, whose value is "10", which indicates that the slot interval between the DCI on the first secondary cell and the PDSCH scheduled by the terminal is set to be the second value "1" and the number of MIMO layers is set to be the first value "2".
The 3 rd first information field of the DCI format includes 2 bits, whose value is "10", indicating that the terminal does not detect the PDCCH in 10 time slots after receiving the DCI on the second secondary cell. The 3 rd second information field of the DCI format includes 1 bit, whose value is "0", and indicates that the slot interval between the DCI in the second auxiliary cell and the PDSCH scheduled by the terminal is set to be the first value "0" and the number of MIMO layers is set to be the first value "2". Or, the 3 rd second information field of the DCI format is 10, which indicates that the slot interval of the DCI on the second secondary cell and the PDSCH scheduled by the terminal is set to a second value "1" and the number of MIMO layers is set to a first value "2".
As can be seen from the above examples, the method for sending and receiving the energy saving parameter provided in the embodiments of the present invention can save the instruction for implementing the energy saving parameter, provide support for the terminal to perform energy saving processing, and is beneficial to the terminal to reduce energy consumption.
Based on the method, the embodiment of the invention also provides equipment for implementing the method.
