Description
The present application claims priority of chinese patent application with application number 201110003133.0 entitled "discontinuous reception method, user equipment and base station" filed by chinese patent office on 7/1/2011, which is incorporated herein by reference in its entirety.
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a discontinuous reception method, a user equipment, and a base station.
Background
At present, a small base station, such as a Pico (micro base station), a HeNB (home base station), a Femto (micro base station), a Relay base station, and other wireless access points, may be placed in a coverage area of a macro enb (macro base station) of an LTE (long term evolution), so that a UE (user equipment) is under dual coverage of the macro enb and the small base station, and the maximum capacity that the system can obtain is the sum of capacities of the macro enb and the small base station, and the entire communication system has a higher capacity than a conventional LTE macro base station network. Under the scenes of office buildings, shopping malls, campus networks and the like, the heterogeneous deployment of the small base stations and the macro base stations can effectively enhance network coverage and improve spectrum efficiency, and the small base stations can be accessed to a network in a wired or wireless mode.
In such a heterogeneous network, a UE can only connect to one cell, which is called a serving cell of the UE, and a base station may generally have one or more cells. If the small-sized base station and the macro base station adopt the same-frequency deployment, all the base stations send downlink signals on the same carrier wave, wherein the downlink signals comprise downlink control domain signals and downlink data domain signals. In order to reduce energy consumption caused by monitoring downlink information by the UE, the prior art provides a DRX (discontinuous reception) technique, in which a base station sets various timers, parameter sets of timer durations, and start principles of the timers, so that the UE does not continuously monitor the downlink information in a time dimension, monitors the downlink information when the UE is in an active state, and does not monitor the downlink information when the UE is in a non-active state, thereby avoiding energy consumption for receiving the downlink information by the UE in the inactive state. When the base station sets the time duration of various timers, the service performance or measurement requirements of the UE are usually considered, for example, the UE with high service rate requirement sets the timer to make the UE in an active state for a long time within a specified time, and the UE with low service rate requirement sets the timer to make the UE in an active state for a short time within the specified time. The existing DRX technology enables the UE to meet the service performance or measurement requirements by setting various timer parameters, reduces unnecessary monitoring and reduces the energy consumption of the UE.
In the course of implementing the present invention, the inventors found that the above prior art has at least the following disadvantages:
due to the interference problem that may be brought by the heterogeneous network, the base station usually uses a TDM (Time-division multiplexing) technique to send signals only on specific Time-frequency resources of some subframes, and rarely sends signals on Time-frequency resources in an ABS (almost blank subframe), thereby ensuring the service requirement or performance requirement of the UE. In a TDM scenario, the existing scheduling method of the DRX technique may result in that the UE energy consumption and the service requirement or performance requirement of the UE cannot be effectively balanced and guaranteed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention relates to a heterogeneous network, wherein the heterogeneous network is characterized in that a small base station, such as a Pico, HeNB, Femto, Relay and other wireless access points, is placed in the coverage range of a macro base station, so that UE is under the dual coverage of a macro eNB and the small base station. When the small-sized base station and the macro base station are deployed at the same frequency, the UE may be interfered by a cell signal of another base station, especially downlink interference, when communicating with its serving cell. In general, the interfered cell is called a victim cell, and the cell interfering with this UE is called an aggressor cell. For example, referring to fig. 1, a HeNB and a Pico are placed in a macro base station, a serving cell of a UE1 and a UE2 is the macro base station, a serving cell of a UE3 is the Pico, a current UE1 is located at the edge of the HeNB, but has no capability of accessing the HeNB, and a UE3 is located within the Pico. At this time, the signal of the macro base station received by the UE3 is an interference signal, the cell affected by the UE3 is the macro base station, the affected cell is Pico, the signal of the HeNB received by the UE1 is an interference signal, the cell affected by the UE1 is the HeNB, and the affected cell is the macro base station.
The embodiment of the invention also relates to a TDM technology to reduce the interference in the heterogeneous network. In the time division multiplexing technology, a base station only sends signals on specific time frequency resources of certain subframes, and rarely sends signals on the time frequency resources in the ABS, so that the service requirement or the performance requirement of the UE is ensured. In the LTE system, in the time domain, a base station numbers a transmission signal in units of radio frames, one radio frame is 10ms long, a corresponding radio frame number is referred to as sfn (systemframenumber), one radio frame includes ten subframes, the number of the subframes is 0# to 9# subframes, and one subframe is divided into a plurality of time frequency blocks according to the time domain and the frequency domain. When the TDM technology is adopted, a base station of an infringing cell selects some subframes as ABS subframes in a period, and the base station of the infringing cell rarely sends signals on time-frequency resources in the subframes in ABS subframe time; accordingly, the UE to which the victim cell belongs is subjected to low interference from the aggressor cell within the ABS subframe time. For example, 8 scattered subframes are selected as ABS subframes in 40 consecutive subframes (40ms), and the corresponding pattern may have various forms, such as: 1000000010000000100000001000000010000000, where 1 indicates that the subframe is set as an ABS subframe, and 0 indicates that the subframe is set as another subframe, the rule is to select the first subframe as an ABS subframe in every 8 subframes, and of course, other patterns may also be adopted, which is not specifically limited in the embodiment of the present invention. In the time domain, a subframe of the victim cell corresponding to the ABS of the aggressor cell is called a low interference subframe, and the victim cell may send downlink information to the interfered UE only on the low interference subframe. Referring to fig. 2, the upper part is a schematic subframe diagram of an aggressor cell, the lower part is a schematic subframe diagram of a victim cell, a time domain is represented horizontally, 4 consecutive subframes are listed from left to right in the time domain, it is assumed that subframe 1, subframe 2, subframe 3 and subframe 4 are used to represent resource block RB vertically, some resources in the diagram are used to transmit CRS (cell reference signal), some resources are used to transmit DL control signal, some resources are used to transmit data, and some resources are blank cells; and setting the subframe 2 and the subframe 3 as ABS subframes, wherein the two subframes of the victim cell corresponding to the two subframes are low-interference subframes.
The embodiment of the invention also relates to a DRX (discontinuous reception) technology, wherein a base station enables UE (user equipment) to monitor downlink information discontinuously in a time dimension by setting various timers, parameter sets of the time lengths of the timers and starting principles of the timers, the UE monitors the downlink information when being in an activated state and does not monitor the downlink information when being in an inactivated state, so that the UE does not have energy consumption for receiving the downlink information when being in the inactivated state. Referring to fig. 3, the timer includes, but is not limited to, the following:
an OnDurationTimer indicating a PDCCH (physical downlink control channel) subframe number that the UE continuously monitors at the beginning of the DRX cycle;
DRX inactivity timer (DRX-inactivity timer): when the UE successfully decodes a PDCCH subframe indicating (Uplink ) or DL (Downlink, Downlink) first-transmitted data, the timer is started and in an active state, and the UE needs to continuously monitor a plurality of subframes within the time;
a harq rtt timer (hybrid automatic repeat request roundtrip timer) indicating that the UE starts an active state after continuously experiencing a minimum number of subframes before expecting to receive a dl harq data;
a DRX retransmission timer (DRX-retransmission timer) for specifying the number of PDCCH subframes that the UE needs to continuously monitor when the UE desires to acquire downlink retransmission;
when the HARQ RTT timer expires, the UE enters an active state and starts a DRX retransmission timer, and the UE is in the active state within the time of the DRX retransmission timer;
a DRX start offset value (drxStartOffset) for indicating a subframe position corresponding to a DRX cycle start time;
a DRX cycle (DRXCycle) indicating an OnDuration period and a time including a periodic repetition of a subsequent possible inactive state;
a DRX short Cycle (shortDRX-Cycle) for indicating the time length of the DRX short Cycle when the UE is in the DRX short Cycle;
a DRX long Cycle (longDRX-Cycle) for indicating a time length of each DRX long Cycle when the UE is in the DRX long Cycle.
A DRX short cycle timer (drxShortCycleTimer) for indicating the corresponding continuous sub-frame number when the UE is in the DRX short cycle state;
the DRX period is divided into a DRX short period and a DRX long period, the UE in the DRX short period timer works according to the DRX short period configuration, and when the corresponding time of the DRX short period timer expires, the UE works according to the DRX long period configuration.
The victim cell referred to in any embodiment of the present invention refers to a base station to which the victim cell belongs, such as eNB, for convenience of description, abbreviated as victim cell, and the aggressor cell refers to a base station to which the aggressor cell belongs, such as eNB, for convenience of description, abbreviated as aggressor cell, and therefore, it is not particularly stated in each step.

Specifically, the victim cell may inform the UE of the first subframe set through RRC signaling, or mac ce, or PDCCH signaling.
603: and after receiving the first subframe set, the UE monitors the PDCCH and/or performs measurement in the first subframe set.
In this embodiment, specifically, the UE may wake up in the first subframe set, be in an active state, and perform monitoring of the PDCCH and/or measurement.
Referring to fig. 7, a diagram of a first subframe set is shown. The upper part is a subframe set corresponding to an active state in DRX configuration information of a damaged cell, the middle part is a subframe set of the damaged cell corresponding to the whole set or the subset of the ABS of an infringing cell, and the lower part is a first subframe set obtained by intersecting the two sets.
The DRX configuration information in this embodiment may include: at least one DRX configuration parameter, wherein a PDCCH subframe corresponding to the DRX configuration parameter can be a PDCCH subframe specified by an existing protocol, and can also be a PDCCH subframe of a victim cell corresponding to an almost blank subframe of an infringement cell; alternatively, the subframe corresponding to the DRX configuration parameter may be a subframe specified by an existing protocol, or may also be a subframe of a victim cell corresponding to an almost blank subframe of an aggressor cell, which is not specifically limited in the embodiment of the present invention.
In the two methods provided by this embodiment, a first subframe set is obtained by combining DRX configuration information of a victim cell and ABS related information of an aggressor cell, and the UE monitors a PDCCH and/or measures according to the set, so as to keep the UE capable of effectively monitoring data of low-interference subframes in DRX configuration and measure the low-interference subframes, thereby ensuring effectiveness of scheduling and measurement accuracy requirements, and avoiding unnecessary energy consumption of the UE, so that the energy consumption of the UE is effectively balanced and ensured with the service requirements or performance requirements of the UE. In addition, the first subframe set can be calculated by the base station side or the UE side, and the application is more flexible.
Example 3
On the basis of embodiment 1 or 2, this embodiment is improved, in addition to monitoring the PDCCH and/or measuring on the first subframe set, the UE may further monitor the PDCCH and/or measuring according to the specified radio frame number AF and the subframe number AO of the radio frame, see fig. 8, where this embodiment provides a first method for discontinuous reception, including:
801: the detailed process of acquiring the first subframe set by the UE in the victim cell is the same as that described in embodiment 1 or 2, and is not described herein again.
802: and the victim cell calculates the activation period T of the UE, the offset value Tm _ offset of the initial subframe position of the activation state in the activation period relative to the initial subframe position of the activation period and the duration Tdelay of the UE in the activation state according to the measurement precision requirement and the service scheduling requirement of the UE and the ABS information of the aggression cell.
In this embodiment, the activation period of the UE refers to a period in which the UE needs to wake up to perform measurement or scheduling, and is denoted by T; the offset value of the starting subframe position of the active state in the active period relative to the starting subframe position of the active period refers to whether the active state in the active period starts from the starting subframe position of the active period and how far away from the starting subframe position of the active period, and is represented by Tm _ offset; the duration of the UE keeping the active state refers to a duration of the UE keeping the active state within the above active period T, and is denoted by Tdelay.
For example, if the UE needs to maintain the measurement accuracy requirement or the scheduling frequency requirement of 2 subframes in 60ms, there should be one subframe for measurement or scheduling in every 30ms subframe, and if the sample affecting the cell ABS is 1/8(10000000), there are 1 low-interference subframe corresponding to the ABS in every 8 radio subframes of the victim cell, so that the measurement is performed every 24ms, and thus it can be calculated: t24 ms, Tm _ offset 0ms (or 9ms or 17ms), Tdelay 1 ms.
803: and the victim cell calculates the frame number AF of the corresponding radio frame and the subframe number AO of the corresponding radio frame according to the activation period T, the offset value Tm _ offset and the initial subframe position of the activation period T.
In this embodiment, there may be one or more activation periods in a measurement or scheduling period of the UE, and when there are multiple activation periods, the starting subframe position of the activation period refers to the starting subframe position of the first activation period in the multiple activation periods.
804: and the victim cell sends the AF, AO and Tdelay obtained by calculation to the UE.
805: and after receiving the measurement, the UE monitors the PDCCH and/or performs measurement in the first subframe set, and monitors the PDCCH and/or performs measurement according to Tdelay at the subframes corresponding to the AF and the AO.
It is understood that the above step 801 is an optional step, and the UE may directly monitor the PDCCH and/or measure according to the specified radio frame number AF and the radio frame number AO, and there may be no inevitable relation between the scheme in this case and the scheme of the previous embodiment 1 or 2.
Similar to the first method, the present embodiment further provides a second discontinuous reception method, which is different only in that the AF and the AO are calculated by the UE, and referring to fig. 9, the method specifically includes:
901: the detailed process of acquiring the first subframe set by the UE in the victim cell is the same as that described in embodiment 1 or 2, and is not described herein again.
902: and the victim cell calculates the activation period T of the UE, the offset value Tm _ offset of the initial subframe position of the activation state in the activation period relative to the initial subframe position of the activation period and the duration Tdelay of the UE in the activation state according to the measurement precision requirement and the service scheduling requirement of the UE and the ABS information of the aggression cell.
903: the victim cell sends T, Tm _ offset and Tdelay to the UE.
904: after receiving the information, the UE calculates the frame number AF of the corresponding radio frame and the subframe number AO of the corresponding radio frame according to the T, the Tm _ offset and the initial subframe position of the activation period.
In steps 901 to 904, the UE may pre-store Tm _ offset agreed with the victim cell, so that the victim cell does not need to send Tm _ offset to the UE, and the UE directly performs calculation of AF and AO according to the locally stored Tm _ offset; similarly, the UE may also store the Tdelay agreed with the victim cell in advance, and the victim cell does not need to send the Tdelay to the UE, and the UE directly performs the calculation of the AF and the AO according to the locally stored Tdelay. For example, when the position corresponding to Tm _ offset agreed in advance between the UE and the victim cell is the active period initial subframe position, that is, Tm _ offset is 0, the victim cell does not need to send Tm _ offset to the UE.
The starting subframe position of the activation period T may be any of the following:
a: the victim cell is pre-designated and sent to the UE;
b: the starting subframe position of the DRX period to which the UE belongs at the current moment or the starting subframe position of the first DRX period in the UE measurement or scheduling period;
c: the radio frame number and the subframe number corresponding to the starting subframe position of the activation period are both predetermined values, for example, the radio frame number and the subframe number are both 0.
905: and the UE monitors the PDCCH and/or the measurement in the first subframe set and monitors the PDCCH and/or the measurement according to Tdelay at the subframes corresponding to the AF and the AO.
It is understood that the above step 901 is an optional step, and the UE can directly monitor the PDCCH and/or measure according to the specified radio frame number AF and the radio frame number AO, and there may be no inevitable connection between the scheme in this case and the scheme of the previous embodiment 1 or 2.
Similar to the second method, the present embodiment further provides a third method of discontinuous reception, which is different only in that T, Tm _ offset and Tdelay are calculated by the UE, see fig. 10, and specifically includes:
1001: the detailed process of acquiring the first subframe set by the UE in the victim cell is the same as that described in embodiment 1 or 2, and is not described herein again.
1002: the UE calculates an activation period T of the UE, an offset value Tm _ offset of the initial subframe position of the activation state in the activation period relative to the initial subframe position of the activation period, and the duration Tdelay of the UE in the activation state according to the measurement precision requirement and the service scheduling requirement of the UE and the ABS information of the affecting cell.
1003: and the UE calculates the frame number AF of the corresponding radio frame and the subframe number AO of the corresponding radio frame according to the T, the Tm _ offset and the initial subframe position of the activation period.
The starting subframe position of the activation period T may be any of the following:
b: the starting subframe position of the DRX period to which the UE belongs at the current moment or the starting subframe position of the first DRX period in the UE measurement or scheduling period;
c: the radio frame number and the subframe number corresponding to the starting subframe position of the activation period are both predetermined values, for example, the radio frame number and the subframe number are both 0.
1004: and the UE monitors the PDCCH and/or the measurement in the first subframe set and monitors the PDCCH and/or the measurement according to Tdelay at the subframes corresponding to the AF and the AO.
In the above three methods of the present embodiment, when the starting subframe position of the activation period is the above mode a, specifically, AF and AO may be calculated according to the following formulas:
when (subframe number of radio frame corresponding to downlink subframe + subframe number corresponding to downlink subframe-subframe number corresponding to preset subframe C × subframe length of radio frame-subframe number corresponding to preset subframe C) modeT is Tm _ offset, the subframe number and subframe number of the corresponding downlink subframe are AF and AO.
In the above three methods of the present embodiment, when the starting subframe position of the activation period is the above mode B, specifically, AF and AO may be calculated according to the following formulas:
when (subframe number of radio frame corresponding to downlink subframe + subframe number of radio frame corresponding to downlink subframe-subframe number corresponding to DRXcycle starting subframe x subframe length of radio frame-subframe number corresponding to DRXcycle starting subframe) modeT is Tm _ offset, the subframe number and subframe number of corresponding downlink subframe are AF and AO.
In the three methods of this embodiment, when the starting subframe position of the activation period is the mode C, and the radio frame number and the subframe number are both 0, specifically, AF and AO may be calculated according to the following formulas:
when the activation time T is a multiple of the subframe length of the radio frame, the radio frame number and the subframe number of the downlink subframe meet the following conditions:
a radio frame number mode (a subframe length of a first time T/radio frame) corresponding to the downlink subframe is FLOOR (Tm _ offset/10);
the subframe number corresponding to the downlink subframe is equal to the subframe length of the Tm _ offset mode radio frame;
the radio frame number and subframe number of the corresponding downlink subframe are AF and AO.
In the above three methods provided in this embodiment, when Tm _ offset is equal to 0, that is, the position corresponding to Tm _ offset is the activation period initial subframe position, AF and AO may be calculated according to the following formulas:
AF is (the subframe number corresponding to the active period starting subframe × the subframe length of the radio frame + the subframe number corresponding to the active period starting subframe + m × the first time T) the subframe length of the div radio frame;
AO ═ the subframe length of (radio frame number corresponding to the active period starting subframe × subframe length of the radio frame + subframe number corresponding to the active period starting subframe + m × first time T) mod radio frame;
where div represents a rounding operation, mod represents a remainder operation, and m represents 0 or a natural number.
In this embodiment, the sequence of the UE acquiring the first subframe set and the AF, AO, and Tdelay is not limited, and may be interchanged or performed simultaneously.
Specifically, when the victim cell sends the various parameters to the UE, the parameters may be delivered to the UE through RRC signaling or MACCE.
It is understood that the above step 1001 is an optional step, and the UE monitors PDCCH and/or measures according to the specified radio frame number AF and subframe number AO of the radio frame, and there may be no inevitable relation with the scheme of the previous embodiment 1 or 2.
Referring to fig. 11, a diagram of a corresponding set for UE monitoring PDCCH and/or measurement is shown. The upper part is a subframe set corresponding to an active state in DRX configuration information of a victim cell, the middle part is a subframe set of the victim cell corresponding to the full set or the subset of the ABS of an infringing cell, and the lower part comprises two parts: the first part is a first subframe set obtained by taking intersection of the two sets, the second part is a subframe corresponding to the AF and AO obtained by calculation, and the UE monitors the PDCCH and/or measurement at the subframe corresponding to the first part and monitors the PDCCH and/or measurement at the subframe corresponding to the second part.
The DRX configuration information in this embodiment may include: at least one DRX configuration parameter, wherein a PDCCH subframe corresponding to the DRX configuration parameter can be a PDCCH subframe specified by an existing protocol, and can also be a PDCCH subframe of a victim cell corresponding to an almost blank subframe of an infringement cell; alternatively, the subframe corresponding to the DRX configuration parameter may be a subframe specified by an existing protocol, or may also be a subframe of a victim cell corresponding to an almost blank subframe of an aggressor cell, which is not specifically limited in the embodiment of the present invention.
In the three methods provided by this embodiment, a first subframe set is obtained by combining DRX configuration information of a victim cell and ABS related information of an aggressor cell, and AF, AO, and Tdelay are also calculated, and the UE monitors and/or measures a PDCCH according to the first subframe set and subframes corresponding to AF and AO, so that the UE can effectively monitor data of a low-interference subframe under DRX configuration, and measure the low-interference subframe, thereby ensuring validity of scheduling and measurement accuracy requirements, and avoiding unnecessary energy consumption of the UE, so that the energy consumption of the UE is effectively balanced and ensured with the service requirements or performance requirements of the UE. In addition, the AF, AO and Tdelay can be calculated by the base station side and can also be calculated by the UE side, and the application is more flexible.
Example 4
Referring to fig. 12, the present embodiment provides a method for discontinuous reception, including:
1201: the method comprises the steps that UE receives DRX configuration information of an affected cell sent by the affected cell and receives first time sent by the affected cell;
1202: the UE obtains an active state according to the DRX configuration information and the active state with the retention time length being the first time, and obtains a first subframe set;
1203: the UE performs monitoring for PDCCH and/or measurements within the first set of subframes.
The first time is configured for the victim cell according to the ABS information of the aggressor cell, and further, may be configured according to the measurement accuracy requirement and the service scheduling requirement of the UE, and the ABS information of the aggressor cell.
Similar to the above method, this embodiment further provides another method for discontinuous reception, except that the first subframe set is obtained by the base station and sent to the UE, and with reference to fig. 13, the method specifically includes:
1301: the victim cell configures a first time based on the ABS information of the aggressor cell.
In this embodiment, the first time is used for the UE to maintain the active state. Specifically, the victim cell may configure the first time according to the measurement accuracy requirement and the service scheduling requirement of the UE, and the ABS information of the aggressor cell.
1302: and the victim cell obtains a first subframe set according to the activation state obtained by the DRX configuration information of the victim cell and the activation state with the retention time length being the first time.
1303: and the victim cell sends the first subframe set to the UE.
1304: and after receiving the information, the UE monitors the PDCCH and/or performs measurement in the first subframe set.
In 1202 and 1302 of this embodiment, the first subframe set may be a subframe set obtained by merging an active state obtained according to DRX configuration information of a victim cell and an active state whose retention time length is a first time. Specifically, the first subframe set in 1202 and 1302 may include any one of the following:
a subframe set obtained by taking a union set of a subframe set corresponding to an active state obtained according to the DRX configuration information and a subframe set corresponding to the active state which is kept for the first time from the end time of the active state; or,
a subframe set obtained by taking a union set is carried out on a subframe set corresponding to an active state obtained according to the DRX configuration information and a subframe set corresponding to the active state which is kept for the first time from a specified time after the active state is ended; or,
and performing union set on a subframe set corresponding to the activated state obtained according to the DRX configuration information and a subframe set corresponding to the activated state which is kept for the first time from the specified time in the activated state to obtain the subframe set.
The designated time after the end of the active state may be configured by the victim cell and sent to the UE, or the designated time in the active state may be configured by the victim cell and sent to the UE.
The following illustrates how the first time of the UE is calculated. For example, when the victim cell eNB performs DRX configuration, the onduration timer may be configured as any one of the following sets {1, 2, 3, 4, 5, 6, 8, 10, 20, 30, 40, 50, 60, 80, 100, 200} ms within an existing one cyclelingth time period. In order to ensure the effectiveness of measurement or scheduling, a new keep-alive operation may be added when the eNB configures the onduration timer according to the requirement of the UE measurement accuracy or the scheduling frequency. If the current service of the UE needs to measure or schedule one subframe every 60ms, if drxcyclength is 160ms, 3 subframes are needed in 160ms, and if the probability of almost blank subframes in the ABS pattern is 1/8 probability (1000000010000000100000001000000010000000), the onduration timer may be configured to be 17ms or a value greater than 17 ms. In this way, the Ondustriationtimer is extended, ensuring measurement accuracy and the frequency requirements of scheduling.
Referring to fig. 14, the active state is maintained for the first time from the end of the active state of the onduration timer. Referring to fig. 15, the left part is an active state that starts to keep a first time at a specified time after the active state end time of the onduration timer, the specified time may be configured to the UE by the eNB of the victim cell, and may be implemented by adding a new timer for timing, and when the timer expires, the UE wakes up to keep the active state according to the first time, and monitors the PDCCH and/or performs measurement. The right part in fig. 15 is an active state that is maintained for a first time from a designated time within the active state of the onduration timer, at which the UE wakes up to maintain the active state for the first time.
The DRX configuration information in this embodiment may include: at least one DRX configuration parameter, wherein a PDCCH subframe corresponding to the DRX configuration parameter can be a PDCCH subframe specified by an existing protocol, and can also be a PDCCH subframe of a victim cell corresponding to an almost blank subframe of an infringement cell; alternatively, the subframe corresponding to the DRX configuration parameter may be a subframe specified by an existing protocol, or may also be a subframe of a victim cell corresponding to an almost blank subframe of an aggressor cell, which is not specifically limited in the embodiment of the present invention.
Of course, the two methods provided in this embodiment may also be applied in combination with the method in embodiment 3 in which the UE performs PDCCH monitoring and/or measurement according to the AF and AO, and the UE monitors the PDCCH and/or measurement in the first subframe set obtained by the DRX configuration information and the first time, and also monitors the PDCCH and/or measurement at the subframes corresponding to the AF and the AO, which is not specifically limited in this embodiment of the present invention.
In the two methods provided by this embodiment, a first subframe set is obtained according to DRX configuration information of a victim cell and a first time of a UE, and the UE monitors and/or measures a PDCCH according to the set, so that the UE can effectively monitor data of a low-interference subframe in DRX configuration and measure the low-interference subframe, thereby ensuring scheduling effectiveness and measurement accuracy requirements, and avoiding unnecessary energy consumption of the UE, so that the energy consumption of the UE and the service requirement or performance requirement of the UE are effectively balanced and ensured. In addition, the first subframe set can be obtained by calculation of the base station side or calculation of the UE side, the first time can be allocated to the UE by the base station side for obtaining the first subframe set, and the first subframe set can also be obtained by the base station without being sent to the UE, so that the application is more flexible.

wherein the designated set of subframes is a set of subframes of the victim cell corresponding to a full or subset of almost blank subframes, ABSs, of the aggressor cell.
In this embodiment, after receiving the designated subframe set, the UE performs PDCCH monitoring and/or measurement, which may include any one of the following:
1) after receiving the appointed subframe set, the UE spontaneously wakes up in the subframe set and monitors the PDCCH and/or performs measurement;
specifically, for example, when the UE has insufficient measurement subframes or measurement sampling is not uniform enough due to heavy traffic or measurement reliability is better, the UE wakes up in the subframe set, and because the subframes are low-interference subframes, measurement of the UE will be effective, thereby increasing measurement opportunities; or the UE may be scheduled on these low interference subframes, thereby increasing the scheduling opportunities.
2) The victim cell can also send an indication to the UE, and the UE spontaneously wakes up in the subframe set after receiving the indication and the specified subframe set and carries out monitoring of the PDCCH and/or measurement;
3) the victim cell can also send a Bitmap of the designated subframe set to the UE, and after receiving the designated subframe set and the Bitmap, the UE monitors the PDCCH and/or performs measurement on a subframe corresponding to the Bitmap in the designated subframe set;
4) the UE performs monitoring for PDCCH and/or measurements only within the designated set of subframes and/or ignores subframes other than the designated set of subframes.
In the method provided by this embodiment, the subframe set of the victim cell corresponding to the almost blank subframe ABS full set or subset of the aggressor cell is sent to the UE, so that the UE monitors the PDCCH and/or measures according to the subframe set of the victim cell, thereby ensuring the validity and measurement accuracy requirements of UE scheduling.

wherein the DRX configuration information comprises: the duration of the DRX cycle, the DRX short cycle, and the long cycle are all integer multiples of 8ms, and the subframe position corresponding to the DRX start offset value (drxStartOffset) is the position of the low-interference subframe of the victim cell corresponding to the almost blank subframe ABS of the aggressor cell.
In this embodiment, the impact of the HARQ mechanism needs to be considered when the abscattern is designed, that is, in every 8ms (8 subframes), a victim cell needs to have one low-interference subframe to meet the HARQ scheduling requirement of the received interfering UE, which is also the reason why the abscattern can be set to 1000000010000000100000001000000010000000. Therefore, in the scenario of using ABS, the duration of the DRX cycle, including the DRX short cycle and the DRX long cycle, may be set to be an integer multiple of 8ms, such as 16ms, 32ms, and so on. And sets a subframe position corresponding to the DRX start offset value (drxStartOffset) as a position of a low interference subframe of the victim cell corresponding to the aggressor cell ABS.
The content of the DRX configuration information in this embodiment may be applicable to any of the above embodiments related to the DRX configuration information, and in any of the above embodiments, the related DRX configuration information may include: the duration of the DRX cycle, the DRX short cycle, and the long cycle are all integer multiples of 8ms, and the subframe position corresponding to the DRX start offset value (drxStartOffset) is the position of the low-interference subframe of the victim cell corresponding to the almost blank subframe ABS of the aggressor cell.
In the method provided by this embodiment, by configuring that the DRX cycle, the DRX short cycle, and the DRX long cycle are all integer multiples of 8ms, and the subframe position corresponding to the DRX starting offset value (drxStartOffset) is the position of the low-interference subframe of the victim cell corresponding to the almost blank subframe ABS of the aggressor cell, the UE performs monitoring and/or measurement of the physical downlink control channel PDCCH according to the DRX configuration information, which can fully meet the requirement of the HARQ mechanism.

Example 14
This embodiment provides a base station, where the base station includes a victim cell, and the base station includes:
the processing module is used for sending a designated subframe set to User Equipment (UE) so that the UE monitors a physical layer downlink control channel (PDCCH) and/or measures in the designated subframe set;
wherein the designated set of subframes is a set of subframes of the victim cell corresponding to a full or subset of almost blank subframes, ABSs, of the aggressor cell.
Wherein the processing module comprises:

and a second processing unit, configured to send a bitmap of the designated subframe set to the UE, where after receiving the designated subframe set and the bitmap, the UE performs PDCCH monitoring and/or measurement at a subframe corresponding to the bitmap in the designated subframe set.

In this embodiment, the subframe set of the victim cell corresponding to the almost blank subframe ABS full set or subset of the aggressor cell is sent to the UE, so that the UE monitors the PDCCH and/or measures according to the subframe set of the victim cell, thereby ensuring the validity and measurement accuracy requirements of UE scheduling.
Example 15
This embodiment provides a base station, where the base station includes a victim cell, and the base station includes:
a sending module, configured to send discontinuous reception DRX configuration information of the victim cell to user equipment UE, so that the UE performs monitoring and/or measurement of a physical layer downlink control channel PDCCH according to the DRX configuration information;
wherein the DRX configuration information comprises: the time lengths of the DRX period, the DRX short period and the DRX long period are all integral multiples of 8ms, and the subframe position corresponding to the DRX starting offset value is the position of a low-interference subframe of an affected cell corresponding to an almost blank subframe ABS of an affecting cell.
In this embodiment, by configuring that the DRX cycle, the DRX short cycle, and the DRX long cycle are all integer multiples of 8ms, and the subframe position corresponding to the DRX starting offset value (drxStartOffset) is the position of the low-interference subframe of the victim cell corresponding to the almost blank subframe ABS of the aggressor cell, the UE performs monitoring and/or measuring of the physical downlink control channel PDCCH according to the DRX configuration information, which can fully meet the needs of the HARQ mechanism.
Example 16
When the UE interacts with the base station, it needs to report its CQI (channel quality index) to the base station, so that the base station schedules the UE according to the reported CQI. The reporting modes of the CQI are divided into two types: periodic reporting and aperiodic reporting. For periodic CQI reporting, the eNB may give an indication in the higher layer signaling of the current subframe, and the UE will perform periodic CQI measurement and reporting in the subsequent time. For aperiodic reporting, after the eNB sends the indication on the PDCCH of the current subframe, the UE will perform aperiodic CQI measurement and reporting subsequently. After introducing the ABS technology, the periodic CQI reporting of the UE introduces the periodic CQI measurement and reporting of the UE aiming at the ABS pattern and the periodic measurement and reporting aiming at the non-ABS pattern. Aperiodic CQI measurement for the UE with respect to the ABS pattern and the non-ABS pattern, respectively, is introduced for aperiodic CQI reporting by the UE, and then the UE reports the measurement result to the eNB. The periodic CQI measurement is preconfigured by the eNB in the higher layer RRC signaling. But the triggering for aperiodic CQI measurement and reporting is given by the PDCCH indication. And for the aperiodic CQI measurement and report of whether the ABS pattern or the non-ABS pattern is initiated, whether the subframe where the aperiodic report instruction issued by the eNB is located is ABS or non-ABS is determined. If the aperiodic CQI measurement reporting instruction is sent on the ABS subframe, the UE executes aperiodic CQI measurement and reporting of the ABS pattern; the UE performs aperiodic CQI measurement and reporting of the non-ABS pattern if the aperiodic CQI measurement reporting indication is sent on a non-ABS subframe. Considering that the UE may move from the edge of the victim cell to the center of the victim cell, the CQI quality of the UE on the non-ABS subframes needs to be evaluated and reported to the eNB, so that the eNB can decide whether the UE is scheduled only on the ABS subframes, and therefore, the UE needs to monitor its information on the non-ABS subframes in order to obtain the above-mentioned indication that the eNB allows the UE to perform aperiodic CQI measurement and reporting. The object of aperiodic CQI measurement and reporting for non-ABS patterns is non-ABS subframes. The non-ABS pattern may indicate these reported objects.
Fig. 18 shows a flowchart of a method for discontinuous reception according to this embodiment, where the method includes:
s181: the method comprises the steps that the UE receives one subframe set or a plurality of subframe sets designated by a cell; one subframe set is an almost blank subframe ABS full set or a subset and/or a non-ABS subframe set; the non-ABS subframe set is all or part of subframes except the almost blank subframe ABS full set, which means that the UE can listen for normal subframes outside the ABS full set or subset; the non-ABS subframe set can be specifically used for monitoring aperiodic Channel Quality Indicator (CQI) measurement and reporting indication of a non-ABS pattern;
s182: the UE monitors a physical layer downlink control channel (PDCCH) and/or measures in the one or more subframe sets.
In this embodiment, after receiving the one or more designated subframe sets, the UE performs PDCCH monitoring and/or measurement, which may include any of the following manners:
(1) and after receiving the appointed subframe set, the UE autonomously monitors the PDCCH and/or performs measurement in the subframe set.
Specifically, for example, when the UE has insufficient measurement subframes or measurement sampling is not uniform enough due to heavy traffic or measurement reliability is better, the UE wakes up in the subframe set to perform the monitoring or measurement, and because ABS subframes in the subframes are low-interference subframes, the measurement of the UE will be effective, thereby increasing measurement opportunities; or the UE may be scheduled on these low interference subframes, thereby increasing the scheduling opportunities. If the UE can obtain the indication information of the non-ABS subframes in the subframes and reports the result, the channel of the UE on the non-ABS subframes is good, if the UE cannot obtain the indication information of the non-ABS subframes in the subframes due to interference, the aperiodic measurement result of the non-ABS pattern cannot be reported, and the eNB cannot receive the relevant information, the channel quality of the UE on the non-ABS subframes is still poor by default, which is beneficial for the eNB to configure the subsequent scheduling information of the UE.
(2) The victim cell can also send an indication to the UE, and the UE autonomously monitors the PDCCH and/or measures in the subframe set after receiving the indication and the specified subframe set;
(3) the victim cell can also send a Bitmap of the appointed subframe set to the UE, and after the UE receives the appointed subframe set and the Bitmap, the UE monitors the PDCCH and/or performs measurement on the subframe indicated by the Bitmap;
(4) the UE performs monitoring for PDCCH and/or measurements only within the designated set of subframes, and/or ignores subframes outside the designated set of subframes. I.e. the UE does not make any PDCCH monitoring and/or measurements on subframes other than said designated set of subframes.
In the method provided by this embodiment, the subframe set of the victim cell corresponding to the almost blank subframe ABS full set or subset of the aggressor cell and the non-ABS subframe set are sent to the UE, where the non-ABS subframe set is used for aperiodic CQI measurement and reporting indication for the UE to monitor a non-ABS pattern, so that the UE monitors the PDCCH and/or measures according to the specific subframe set, thereby ensuring the validity and measurement accuracy requirements of UE scheduling.
