Description

[0001] This application is a divisional application. The application number of the original application is 201910760919.3, and the original application date is August 16, 2019. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present invention relates to the field of communication technology, and in particular to a method for indicating energy-saving information, a base station and a user terminal. Background Art

[0003] In the fifth generation (5th Generation, 5G) mobile network New Radio (NR) system, in order to support larger bandwidth, higher throughput and more complex services and more complex processing technologies to match them, energy-saving design of user equipment (UE) becomes very necessary. Energy-saving design can save power consumption of user terminals, thereby improving user experience, which is very important for the industrialization of 5G. At present, in the energy-saving topic of UE, people have proposed a method of using the physical downlink control channel (Physical Downlink Control Channel, PDCCH) as an energy-saving channel to indicate the energy-saving information of the UE. By using the energy-saving information of the UE, the UE can obtain the minimum value of the cross-slot scheduling before decoding the scheduling PDCCH, so that the UE can turn off some sending equipment and reduce the processing speed of the main components, thereby achieving energy-saving effects.

[0004] The current standard defines the use of downlink control information (DCI) to carry energy-saving information. In the prior art, a target DCI carrying energy-saving information is only used to indicate a cross-time slot scheduling information, which will lead to an increase in DCI overhead and an increase in power consumption of UE blind detection. It can be seen that although the prior art can achieve the effect of energy saving, the energy saving effect is not ideal. Summary of the invention

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

[0097] The terms "first" and "second" in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "comprising" and any variation thereof are intended to cover non-exclusive protection. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0099] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0100] At present, a target DCI carrying energy-saving information is only used to indicate a cross-time slot scheduling information and when the energy-saving information is carried on the downlink (DL) scheduling DCI and the uplink (UL) scheduling DCI, it can only be used to indicate the cross-time slot scheduling information on the DL scheduling DCI and the UL scheduling DCI, respectively, which will lead to an increase in the DCI overhead and an increase in the power consumption of the UE blind detection. It can be seen that although the existing technology can achieve the effect of energy saving, the energy saving effect is not ideal.

[0101] In view of this, an embodiment of the present application provides a method for indicating energy-saving information, which carries the first energy-saving information in the target DCI of the first time unit, wherein the first energy-saving information is used to indicate at least one cross-time slot scheduling information contained in at least one time unit starting from the first time unit or a time unit after the first time unit, and sends the target DCI to the user terminal, so that a target DCI carrying energy-saving information can indicate multiple cross-time slot scheduling information, solves the technical problems that a target DCI carrying energy-saving information cannot indicate or ambiguously indicates multiple cross-time slot scheduling information, the target DCI carrying energy-saving information is lost due to transmission, resulting in increased UE power consumption, and the need for more target DCI carrying energy-saving information leads to increased target DCI overhead and UE blind detection power consumption, reduces UE power consumption and improves energy saving effect.

[0130] The minimum time interval between CSI-RS reception and PDCCH reception associated with an SRS request.

[0131] In a specific implementation process, the energy-saving information may directly indicate that the scheduling DCI is the scheduling of the current time slot or the scheduling of the cross-time slots through the first information indicating the cross-time slot scheduling information, or indirectly indicate that the scheduling DCI is the scheduling of the current time slot or the scheduling of the cross-time slots through the second information indicating the cross-time slot scheduling information. For ease of understanding, the following is explained in the form of an example:

[0132] For example, if the energy-saving information indicates that the minimum value of the time interval between PDSCH transmission and PDCCH reception in the second information or the minimum value of the time interval between PDCCH transmission and PDSCH reception K0 is equal to A, and the minimum value of the time interval between PUSCH transmission and PDCCH reception or the minimum value of the time interval between PDCCH transmission and PUSCH reception K2 is equal to B, where A and B are both positive integers, then it is determined that the first information is used to indicate that the scheduling DCI is cross-slot scheduling;

[0133] If the energy-saving information indicates that the minimum time interval between PDSCH transmission and PDCCH reception in the second information or the minimum time interval between PDCCH transmission and PDSCH reception K0 is equal to A, and the minimum time interval between PUSCH transmission and PDCCH reception or the minimum time interval between PDCCH transmission and PUSCH reception K2 is equal to B, where A is equal to zero and B is not less than zero, then it is determined that the first information is used to indicate that the scheduling DCI is cross-slot scheduling.

[0134] The implementation method introduced in the above embodiment is an explanation for a specific carrier, wherein the selection of the carrier is not restricted and can be the multiple situations listed above, or multiple carrier scheduling can be performed. Based on this situation, in an embodiment of the present application, if the activation part bandwidth BWP of the first carrier for scheduling DCI for data transmission is configured as cross-slot scheduling, wherein the first carrier is a carrier set including at least one carrier, when the activation BWP of the first carrier is switched, the problem of restricted cross-slot scheduling may occur. Based on this problem, in an embodiment of the present application, if the activation part bandwidth BWP of the first carrier for scheduling DCI for data transmission is configured as cross-slot scheduling, the cross-slot scheduling parameter is determined to be the maximum value of the first time interval and the first parameter; wherein the first carrier is a carrier set including at least one carrier, the first time interval is used to indicate the time interval for the activation BWP of the first carrier to switch from the first BWP to the second BWP, and the first parameter is used to indicate the cross-slot scheduling parameter of the second BWP configuration.

[0135] Specifically, after the activated BWP of the first carrier ends data transmission, a switching signaling is sent on the second carrier, wherein the second carrier is a carrier set including at least one carrier for data scheduling, and the switching signaling is used to indicate the switching of the activated BWP of the first carrier. According to the switching signaling, the activated BWP of the first carrier is switched from the first BWP to the second BWP.

[0136] Step 202: Send the target DCI to the user terminal.

[0137] In the embodiment of the present application, it is determined whether the target DCI is a DCI already in the existing standard. If the target DCI is a DCI not in the current standard (i.e., the newly defined DCI for carrying energy-saving information described above), the period configured by static, semi-static, and dynamic signaling is determined as the period for sending the target DCI to the user terminal; if the target DCI is a DCI already in the current standard, the same period of the existing DCI is determined as the period for sending the target DCI to the user terminal. For ease of understanding, the following is an example:

[0138] For example, the existing DCI in the existing standards includes DCI-format-0-0, DCI-format-0-1, DCI-format-1-0, DCI-format-1-1, DCI-format-2-0, DCI-format-2-1, and DCI-format-2-3 defined in the current 38.212 standard or the current 36.212 standard.

[0139] If the target DCI is a DCI in another format other than the DCI defined in the current 38.212 standard or the 36.212 standard, wherein the DCI in another format, or the new DCI, may be a DCI scrambled with a new Radio Network Temporary Identity (RNTI) or a DCI defining a new information domain, such as a downlink DL scheduling DCI, an uplink UL scheduling DCI, a group-common DCI, or a newly defined DCI for carrying energy-saving information. Then determine the period configured by static, semi-static, or dynamic signaling as the period for sending the target DCI to the user terminal;

[0140] If the target DCI is DCI-format-0-0 defined in the current 38.212 standard, the same period of DCI-format-0-0 is determined as the period for sending the target DCI to the user terminal.

[0141] An indication message is generated according to the period, and the indication message and the target DCI are sent to a user terminal.

[0142] In a specific application scenario, the base station may continuously send multiple energy-saving information to the terminal device. If the target DCI carrying the second energy-saving information is sent in the time unit after the first time unit, for example, the second time unit, and the second energy-saving information is used to indicate at least one cross-time slot scheduling information contained in the second time window, then the second time window and the first time window may partially overlap, not overlap, or completely overlap. If the second time window and the first time window partially overlap or completely overlap, there will be a problem that the cross-time slot scheduling information indicated by the first energy-saving information and the cross-time slot scheduling information indicated by the second energy-saving information may be the same or different in the overlapping time window.

[0143] Based on this problem, in an embodiment of the present application, second energy-saving information is carried in the target DCI of the second time unit, wherein the second energy-saving information is used to indicate at least one cross-time slot scheduling information contained in the second time window, and the second time window includes at least one time unit starting from the second time unit or starting from a time unit after the second time unit, and the relationship between the second time window and the first time window includes at least one of partial overlap, non-overlap, and complete overlap, and then the target DCI of the second time unit is sent to the user terminal.

[0144] In an embodiment of the present application, a target DCI carrying energy-saving information can indicate multiple cross-time slot scheduling information, thereby solving the technical problems that a target DCI carrying energy-saving information cannot indicate or ambiguously indicates multiple cross-time slot scheduling information, the target DCI carrying energy-saving information is lost, resulting in increased UE power consumption, and the need for more target DCIs carrying energy-saving information leads to increased target DCI overhead and UE blind detection power consumption, thereby reducing UE power consumption and improving energy saving effects.

[0145] Figure 3 The structure of a user terminal to which the method provided in the embodiment of the present application is applicable. Of course, the method provided in the embodiment of the present application can be applied to a variety of user terminals. It should be understood that Figure 3 The user terminal shown is a detailed description of a user terminal to which the method provided by the embodiment of the present application is applicable, rather than a limitation on the user terminal to which the method provided by the embodiment of the present application is applicable.

[0146] Figure 3The user terminal shown includes a processor 301, a memory 302, a transceiver 303, and a bus interface 304. The processor 301, the memory 302, and the transceiver 303 are connected via the bus interface 304. The transceiver 303 is used to receive a target DCI carrying first energy-saving information sent by a base station in a first time unit, a target DCI carrying second energy-saving information sent in a second time unit, and an indication message indicating a period for the base station to send the target DCI. The memory 302 is used to store program instructions. The processor 301 is used to call the program instructions stored in the memory 302, and execute all steps included in the method for indicating energy-saving information according to the obtained program instructions.

[0147] See also Figure 4 The present application embodiment provides a method for indicating energy-saving information, which can be performed by the aforementioned Figure 3 The user terminal shown is executed. The specific process of the method is described as follows.

[0148] Step 401: Receive target downlink control information DCI carrying first energy-saving information sent by a base station in a first time unit.

[0149] The format of the target DCI carrying the first energy-saving information may be a DCI already included in the existing standard or a DCI not included in the current standard (i.e., the newly defined DCI for carrying energy-saving information described above). For different target DCI formats, the base station sends the target DCI at different periods. Based on this problem, in an embodiment of the present application, if the target DCI is a DCI not included in the current standard, the base station side can send an indication message for indicating the period of sending the target DCI. If the target DCI is a DCI already included in the current standard, the indication message may not be sent in advance.

[0150] In an embodiment of the present application, if the base station sends an indication message in advance, the indication message sent by the base station is received, wherein the indication message is used to indicate the period of the base station sending the target DCI carrying the first energy-saving information in the first time unit, and then the target DCI carrying the first energy-saving information sent by the base station is received according to the period.

[0151] Specifically, the first energy-saving information is used to indicate at least one cross-slot scheduling information contained in the first time window, the first time window includes at least one time unit starting from the first time unit or a time unit after the first time unit, and the cross-slot scheduling information includes at least one of the first information and the second information; wherein, the first information is used to indicate that the scheduling DCI is cross-slot scheduling or current time slot scheduling, and the second information is used to indicate the minimum value of the cross-slot scheduling parameter or the minimum value of the cross-slot scheduling parameter in the time domain resource allocation TDRA list.

[0152] Step 402: Determine, according to the target DCI, at least one cross-time slot scheduling information included in at least one time unit starting from the first time unit or a time unit after the first time unit.

[0153] The cross-slot scheduling information is carried on the scheduling DCI. If the energy-saving information is carried on the DL scheduling DCI and the UL scheduling DCI, there will be a problem that the cross-slot scheduling information can only be used to indicate the DL scheduling DCI and the UL scheduling DCI respectively. Based on this problem, in an embodiment of the present application, if the target DCI is a downlink DL scheduling DCI and indicates the cross-slot scheduling information of the uplink UL scheduling DCI, or the target DCI is a UL scheduling DCI and indicates the cross-slot scheduling information of the DL scheduling DCI, the user terminal falls back to the current time slot scheduling.

[0154] Optionally, in a specific application scenario, the base station may continuously send multiple energy-saving information to the terminal device. If the target DCI carrying the second energy-saving information is sent in the time unit after the first time unit, such as the second time unit, and the second energy-saving information is used to indicate at least one cross-time slot scheduling information included in the second time window, then the second time window and the first time window may partially overlap, not overlap, or completely overlap. Based on this problem, in the implementation of the present application, the target DCI carrying the second energy-saving information sent by the base station in the second time unit is received, wherein the second energy-saving information is used to indicate at least one cross-time slot scheduling information included in the second time window, and the second time window includes at least one time unit starting from the second time unit or starting from the time unit after the second time unit;

[0155] If the second time window partially overlaps or completely overlaps with the first time window, the user terminal determines the cross-time slot scheduling information according to the received target DCI that is closest in time.

[0156] Optionally, the implementation method introduced in the above embodiment is described for a specific carrier, wherein the selection of the carrier is not restricted and may be the multiple situations listed above, or multiple carrier scheduling may be performed. Based on this situation, in an embodiment of the present application, if the activated partial bandwidth BWP of the first carrier for scheduling DCI for data transmission is configured as cross-slot scheduling, wherein the first carrier is a carrier set including at least one carrier, when the first carrier undergoes activation BWP switching, the problem of restricted cross-slot scheduling may arise. Based on this problem, in an embodiment of the present application, if the activated partial bandwidth BWP of the first carrier for scheduling DCI for data transmission is configured as cross-slot scheduling, the user terminal receives a cross-slot scheduling parameter, and the cross-slot scheduling parameter is the maximum value between the first time interval and the first parameter; wherein the first time interval is used to indicate the time interval for the activation BWP of the first carrier to switch from the first BWP to the second BWP, and the first parameter is used to indicate the cross-slot scheduling parameter of the second BWP configuration of the first carrier. Specifically, after the activated BWP of the first carrier ends data transmission, a switching signaling is received on the second carrier, wherein the second carrier is a carrier set including at least one carrier for data scheduling, and the switching signaling is used to indicate the switching of the activated BWP of the first carrier. According to the switching signaling, the activated BWP of the first carrier is switched from the first BWP to the second BWP.
