Embodiment one

The present embodiment illustrates the method provided in an embodiment of the present invention for monitoring DCI from the angle of terminal device.

Referring to Fig. 1, for a kind of flow diagram for the method for monitoring DCI provided in this embodiment.The method of monitoring DCI as shown in Figure 1 includes the following steps S101-S103:

S101:UE sends the last one MAC (Media Access Control, media access control) data packet in this communication process to base station.

Wherein, which can be any one UE connecting with base station.MAC data packet refers to the data packet for meeting MAC protocol, is referred to as MAC layer data packet.

For example, when UE has upstream data to send demand, upstream data to be sent can be packaged into one or more MAC data packets based on MAC protocol, and be sent to base station.Specific: UE sends a MAC data packet to base station every time.If base station is successfully received a MAC data packet of UE transmission, ACK (Acknowledgement, positive to confirm) message for the MAC data packet can be replied to the UE；When UE receives the ACK message, next MAC data packet can be sent to base station, until having sent the last one MAC data packet.

Since the embodiment of the present invention will be known as " communication process " to the process for receiving the ACK message that base station is directed to the reply of the last one MAC data packet sending first MAC data packet in the case where once having upstream data transmission demand.The embodiment of the present invention has the trigger condition of upstream data transmission demand without restriction UE, such as can be any trigger condition in the prior art.

In addition, UE can generally monitor each DCI block in a communication process, i.e., continuously monitor DCI block；Herein, the continuous process for monitoring DCI block is known as ADR (all DCI reception, DCI receive entirely) mode.

For example, UE can increase a sign in each MAC data packet in this communication process；Wherein, the sign be used to indicate the MAC data packet where the sign whether be this communication process the last one MAC data packet.Alternatively, UE only can increase an instruction message in the last one MAC data packet in this communication process, being used to indicate the data packet is the last one MAC data packet in this communication process.Wherein, above-mentioned sign can be the display instruction of 1 bit, be also possible to the case where content of BSR (buffer status report, internal storage state report) is designated as 0 or other particular values.

S102: the UE determines object time point when receiving the target ACK message that the base station is replied；Wherein, the target ACK message is the last one described in the base station is directed to The ACK message that MAC data packet is replied.

Wherein, " target ACK message " can be directed to any one ACK message that the last one described MAC data packet is replied for the base station that UE has been received, or any one ACK message replied for the last one described MAC data packet that UE is not yet received.

It should be noted that base station can determine the quantity for the ACK message that the MAC data packet sent for the UE is replied according to the communication quality of UE.Wherein, which is the integer more than or equal to 1.Generally, the communication quality of UE is poorer, and the quantity is bigger.

It is further to note that, since base station can appoint the quantity for the ACK message that the MAC data packet sent for the UE is replied before this communication process with UE, wherein, the stipulated form can be what agreement provided, or configured based on modes such as system message or dedicated signalings；Therefore, even if UE not yet receives target ACK message, object time point when receiving target ACK message can be determined according to information such as the quantity by remaining on.Certainly, when specific implementation, UE can also determine object time point according to any mode in the prior art.

S103: the UE enters RDR according to the object time point (reduced DCI reception reduces DCI and receives)；Wherein, it in the RDR mode, monitors anchor point DCI block (anchor DCI)；Wherein, the anchor point DCI block is the DCI block that can be used in carrying the scheduling information of the UE that base station is determined according to the object time point, is separated by one or more DCI blocks between the anchor point DCI block of adjacent two.

For example, RDR mode is initially entered at the end of third preset time period of the UE since the object time point；Wherein, third preset time period can be 0, can also be greater than 0.When specific implementation, third preset time period can configure presence, can also configure and be not present；It is configured if it is present the value of third preset time can be by modes such as broadcast message or dedicated signalings.The embodiment of the present invention is to the specific value of the third preset time period without limiting.Within third preset time period, UE is still within ADR mode.It should be noted that being used herein as " third preset time period " to distinguish with other preset time periods herein.

Wherein, in RDR mode, DCI block is divided into anchor point DCI block and non-anchor DCI block by UE.Anchor point DCI block is the DCI block that can be used in carrying the scheduling information of the UE that base station is determined according to the object time point；Wherein, base station determines that the specific implementation of anchor point DCI block can be with reference to hereafter.The scheduling information of the UE cannot be carried on non-anchor DCI block.Non-anchor DCI block can be used in carrying the scheduling information of other UE.

It should be noted that, anchor point DCI block can carry the scheduling information of the UE, but the scheduling information of the UE is carried on not each anchor point DCI block, and since UE cannot know carry the scheduling information of the UE on which anchor point DCI block in advance, therefore under RDR mode, UE needs to monitor each anchor point DCI block.In addition, UE does not need to monitor non-anchor DCI block.

It is further to note that thinking that it has listened to the scheduling information of UE, and receive or send the user data of UE according to the scheduling information when UE is listened to and carried the scheduling information of the UE in anchor point DCI block.Wherein, " user data " here can be uplink user data, or down user data.Namely it can consider that UE has listened to user data.

It is separated by one or more DCI blocks between two anchor point DCI blocks of arbitrary neighborhood；The quantity for the DCI block being separated by between the quantity for the DCI block being separated by between two anchor point DCI blocks of arbitrary neighborhood and any other two adjacent anchor point DCI blocks can be the same or different.Preferably, the DCI block of identical quantity is separated by between two anchor point DCI blocks of arbitrary neighborhood；Thus introduce the concept of " anchor point DCI listening period ".It is specific: to have at least two DCI blocks in an anchor point DCI listening period, specifically there is an anchor point DCI block and at least one non-anchor DCI block；The position of anchor point DCI block in each anchor point DCI listening period is identical, for example, the 2nd DCI block in each anchor point DCI listening period is anchor point DCI block.That is, the interval between two adjacent anchor point DCI is anchor point DCI listening period.

Optionally, anchor point DCI listening period can be with are as follows: the integral multiple of the frame length of a superframe, or, the common multiple at the interval DCI of all covering grades of base station.Wherein, the frame length of a superframe is 64*80ms.Preferably, anchor point DCI listening period are as follows: the frame length of a superframe, Or, the least common multiple at the interval DCI of all covering grades of base station.

When specific implementation, the quantity that DCI block can be used indicates anchor point DCI listening period；It is of course also possible to directly indicate anchor point DCI listening period with the period that ms (millisecond) or s (second) etc. are unit.

It should be noted that generally, anchor point DCI listening period is determined by base station.Further, anchor point DCI listening period is carried and is broadcasted in system message by base station, to notify to all UE under the cell where the UE.In addition, base station also can be used dedicated signaling and notify the anchor point DCI listening period of specific UE to give the specific UE if requirement of the difference UE for anchor point DCI listening period is different.Optionally, if UE obtains anchor point DCI information from broadcast message, and the anchor point DCI period that dedicated signaling issues is had received again, UE preferentially uses the anchor point DCI listening period carried in dedicated signaling at this time.

When specific implementation, UE does not need to obtain anchor point DCI listening period from the broadcast message that base station is sent in each communication process.UE can obtain an anchor point DCI listening period from broadcast message, and be stored in local；In subsequent communication process, if system message is constant, UE directly can obtain anchor point DCI listening period from local.

The present embodiment can be described as: UE enters ADR mode at the beginning of a communication process；And under the triggering of the finish time of the communication process, into RDR mode.

It should be noted that UE is in connected state under ADR mode and RDR mode, base station is that UE retains contextual information at this time.

The method provided in this embodiment for monitoring DCI, UE sends the last one MAC data packet in this communication process to base station, and determine object time point when receiving the target ACK message that base station is replied, wherein, target ACK message is the ACK message that base station is directed to that the last one MAC data packet is replied；To enter RDR mode according to the object time point, in RDR mode, UE monitors anchor point DCI block, wherein being separated by one or more DCI blocks between two adjacent anchor point DCI blocks.That is, UE monitors DCI block under the triggering of the finish time of this communication process under RDR mode, in this way, for UE for needing to monitor DCI block always before connection is eated dishes without rice or wine in release, the technical program can in compared with the prior art The amount of saving energy.

Optionally, if the base station is directed to the last one described MAC data packet and replys at least two ACK messages, the target ACK message is the last one ACK message at least two ACK message.

Based on the optional mode, in one embodiment provided in an embodiment of the present invention, after S101, the method also includes: it receives the base station and is directed to the first ACK message that the last one described MAC data packet is replied, if first ACK message receives correct, so in the follow-up process, it no longer receives the base station and is directed to other ACK messages that the last one described MAC data packet is replied；Wherein, first ACK message is the last one non-ACK message that the base station is directed to that the last one described MAC data packet is replied.If the first ACK message reception failure, UE continues to subsequent ACK message, until being properly received ACK message.

For example, base station is directed to the last one described MAC data packet and continuously transmits two ACK messages to UE, then UE can not receive second ACK message, but UE is still using the receiving time for second ACK message being calculated point as object time point after being properly received first ACK message.

It should be noted that receiving the technical solution that base station is directed to all ACK messages that the last one described MAC data packet is replied compared to UE, the technical solution which provides can reduce the power consumption of UE.In addition, UE can also be after receiving the ACK message that base station is replied for any one MAC data packet, if the ACK message receives correctly, and in the follow-up process, no longer reception base station is directed to other ACK messages that the MAC data packet is replied when specific implementation.

In this embodiment, at time point when S102 may include: according to the first ACK message of reception, object time point when receiving the target ACK message that the base station is replied is determined.For example, the information such as the quantity of ACK message that UE can be replied according to base station for the UE MAC data packet sent, determine object time point.

It optionally, is referring to fig. 2 another method for monitoring DCI provided in this embodiment Flow diagram.The method of monitoring DCI as shown in Figure 2 can also include the following steps S104-S106 after above-mentioned S103

S104: the UE judges the scheduling information for whether listening to the UE on anchor point DCI block in the second preset time period, i.e., whether is stated the user data of user；Wherein, the UE that second preset time period refers to is in the period of RDR mode.

If so, executing S105；If it is not, then executing S106.

Wherein, " user data " can be uplink user data or down user data.The embodiment of the present invention is to the specific value of " the second preset time period " without limiting.

The time point of S105: the UE scheduling information for listening to the UE from anchor point DCI block initially enters ADR mode；Wherein, continuous to monitor DCI block in ADR mode.

S106: the UE enters dormant state, the i.e. long dormant state of Idle state or connected state.

Wherein, UE is in Idle state and is equivalent to the connection that UE is disconnected between base station.That is, base station releases the interface-free resources of UE.The long dormant state that UE is in connected state is equivalent to the interface-free resources that base station releases UE, but base station still retains the contextual information of UE, and UE is facilitated to obtain scheduling resource.

It is the schematic diagram for the process that a kind of UE provided in an embodiment of the present invention is switched to Idle state by connected state referring to Fig. 3.Each lattice in Fig. 3 indicates a DCI block.Wherein, hypographous lattice indicates the DCI block that UE is monitored, and specifically includes: each DCI block under ADR mode and the anchor point DCI block under RDR mode；The lattice of blank indicates the non-anchor DCI block under RDR mode.

The trigger condition that UE enters ADR mode can refer to the prior art；It can be with by the trigger condition of ADR pattern switching to RDR mode are as follows: the finish time of the third preset time period after object time point；It can be with by the trigger condition of RDR pattern switching to Idle state are as follows: UE does not listen to the scheduling information of the UE entering in the second preset time period after RDR mode, i.e. the not no user data of user.

During UE shown in Fig. 3 is by connected state to Idle state, UE is by RDR mould Formula is directly switch to Idle state.It, can be by RDR pattern switching to ADR mode if UE is entering in the second preset time period after RDR mode the scheduling information for listening to the UE when specific implementation；Then, each step of above-described embodiment one can be executed.UE can be executed several times under connected state " from ADR pattern switching to RDR mode; again from RDR pattern switching to ADR mode ", until certain enter RDR mode after the second preset time period in do not listen to the scheduling information of the UE when, until being switched to Idle state.Wherein, arbitrarily RDR mode duration can be the same or different twice, and arbitrarily ADR mode duration can be the same or different twice.

It should be noted that, anchor point DCI block under the quantity of the DCI block that UE is monitored under ADR mode, RDR mode is specially which DCI block, RDR mode duration etc., it can set according to actual needs, one of UE is only schematically illustrated in Fig. 3 by the process of connected state to Idle state.

Embodiment two

The present embodiment illustrates the method provided in an embodiment of the present invention for monitoring DCI from the angle of base station.The explanation of related content can refer to other embodiments herein in the present embodiment.

It referring to fig. 4, is a kind of flow diagram for the method for monitoring DCI provided in this embodiment.The method of monitoring DCI as shown in Figure 4 includes the following steps S401-S403:

The last one media access control MAC data packet in S401: base station receiving terminal apparatus UE this communication process sent.

When specific implementation, after S401, this method can also include: that base station is directed to the last one described MAC data packet to a certain number of ACK messages of UE reply；Wherein, which is the integer more than or equal to 1 that base station is appointed with UE before this communication process.Wherein, which can be what agreement provided, or configured based on modes such as system message or dedicated signalings.

S402: the base station determines the object time point replied when target is just confirming ACK message to the UE；Wherein, the target ACK message be the base station for it is described last The ACK message that a MAC data packet is replied.

It should be noted that " target ACK message " in the present embodiment and " the target ACK message " in embodiment one are same ACK message.In addition, theoretically, " object time point " in the present embodiment in embodiment one " time differed between object time point is the transmission time of target ACK message.It is simple in order to what is described, do not consider the transmission time herein, that is, thinks " the object time point " in embodiment one and " the object time point " in embodiment two is same time point.

S403: the base station determines anchor point DCI block according to the object time point；Wherein, the anchor point DCI block is the DCI block that can be used in carrying the scheduling information of the UE, it is separated by one or more DCI blocks between the anchor point DCI block of adjacent two, the initial time of the anchor point DCI block is identical as the object time point or after the object time point；The object time point reduces DCI reception pattern for entering the UE, and in the reduction DCI reception pattern, the UE monitors the anchor point DCI block.

For example, anchor point DCI block can carry the scheduling information of the UE, but the scheduling information of the UE is carried on not each anchor point DCI block.Specifically, base station sends the scheduling information of the UE on anchor point DCI block if there is the user data for the UE；If not being directed to the user data of the UE, base station does not send the scheduling information of the UE on anchor point DCI block.But since UE cannot know carry the scheduling information of the UE on which anchor point DCI block in advance, under RDR mode, UE needs to monitor each anchor point DCI block.In addition, UE does not need to monitor non-anchor DCI block.

It is further to note that when the scheduling information that base station carries the UE on an anchor point DCI block thinks that it has listened to the scheduling information of UE, and receive or send the user data of UE according to the scheduling information then when UE listens to anchor point DCI block.Namely it can consider that UE has listened to user data.Wherein, " user data " here can be upper Row user data, or down user data.

Wherein, base station according to object time point determine anchor point DCI block specific implementation can refer to it is discussed below.

Optionally, after S403, this method can also include:

S502: base station replys the ACK message for being directed to the last one MAC data packet to UE, and determines time point when executing " reply " movement as object time point.

S503:UE determines the object time point for receiving the ACK message.

It should be noted that, in this document, S502 is identical as " the object time point " in S503.It is further to note that object time point is that base station adds the time point that third preset time point obtains to the time point that UE replys ACK in S502 if base station is configured with third preset time period.

S504: base station determines the anchor point DCI block in each anchor point DCI listening period according to parameter preset；Wherein, parameter preset includes at least one of following information: the interval DCI of the covering grade where the ID (IDentity, identity number) of the UE, anchor point DCI listening period, the UE；The initial time of anchor point DCI block is identical as object time point or after object time point.

Wherein, the ID of UE, that is UE_id, it is including but not limited to any one of following information: C-RNTI (Cell Radio Network Temporary Identifier, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI), TLLI (Temporary Logical Link Identifier, temporary logical link identifier), IMSI (International Mobile SubscriberIdentification Number, international mobile subscriber identity) etc..

When specific implementation, if UE_id longer, UE_id is simplified it is possible to first pass through certain operation rule, simplified UE_id and anchor point DCI listening period is recycled to determine anchor point DCI block.For example, can be using the result being calculated according to formula UE_id mod K as simplified UE_id；Wherein, K is positive integer, and mod indicates modulo operation. It is, of course, also possible to be simplified by other formula to UE_id, will not enumerate herein.

S505: if there is the user data for the UE, base station sends the scheduling information of the UE on anchor point DCI block；If not being directed to the user data of the UE, base station does not send the scheduling information of the UE on anchor point DCI block.

S506:UE enters RDR mode according to object time point, and the anchor point DCI block in each anchor point DCI listening period is determined according to parameter preset；Wherein, parameter preset includes at least one of following information: the interval DCI of the covering grade where UE_id, anchor point DCI listening period, the UE.

It should be noted that S505 is identical as the specific implementation of anchor point DCI block determining in S506, therefore identified anchor point DCI block is also identical.Wherein, specific implementation can be with reference to hereafter.

Step 2: modulo operation being carried out to the ID and M of UE, the position of the anchor point DCI block in each anchor point DCI listening period is obtained, so that it is determined that anchor point DCI block.

For example, utilize formula: M=floor (interval DCI of the covering grade where anchor point DCI listening period div UE) obtains M, wherein floor indicates that rounding operation, div indicate division arithmetic；And each anchor point DCI is obtained using formula R=UE_id mod M and is monitored The position R of anchor point DCI block in period, thus using the R DCI block in each anchor point DCI listening period as anchor point DCI block.

For example, it is assumed that anchor point DCI listening period is 64*80ms, 2*80ms is divided between the DCI of the covering grade where UE；So, M=floor { (64*80ms) div (2*80ms) }=32, illustrates: having 32 DCI blocks in each anchor point DCI listening period.Further, it is assumed that the R obtained according to formula R=UE_id mod M is 2, then, illustrate: the 2nd DCI block of each anchor point DCI listening period is anchor point DCI block.

Mode two: parameter preset includes anchor point DCI listening period；1) and step 2) the anchor point DCI block in each anchor point DCI listening period since object time point is determined according to parameter preset, is included the following steps:

Step 1): using the DCI block from the finish time of the first preset time period since UE enters and reduces the time point of DCI reception pattern as the first anchor point DCI block；

Step 2): will be in each anchor point DCI listening period and be separated by the DCI block of the integral multiple of anchor point DCI listening period as anchor point DCI block with the first anchor point DCI block.

Wherein, the embodiment of the present invention is to the value of the first preset time period without limiting.
