Specific embodiment

For background technique, the prior art lacks the technical solution for solving the collision problem of PDCCH and synchronization signal block.

It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to the accompanying drawing to this The specific embodiment of invention is described in detail.

Fig. 1 is the process signal of a kind of PDCCH of first embodiment of the invention and the collision solution of synchronization signal block Figure, can be used for network side, such as network side base station.With reference to Fig. 1, the collision solution be may comprise steps of:

Step S101: judge whether resource is overlapped for PDCCH and synchronization signal block；

Step S102: when the PDCCH and the synchronization signal block resource are overlapped, the money of the PDCCH is at least abandoned Source lap.

Specifically, in step s101, base station is PDCCH configurating downlink control instructions (Downlink Control Information) when information, it can be determined that the physics whether the PDCCH physical resource of configuration can occupy with synchronization signal block provides Source collides (namely resource overlapping).

As a non-limiting embodiment, base station can receive user capability from user equipment and report information, described It may include decoding rate-matched ability when user decodes PDCCH that user capability, which reports information, and punch decoding capability, with Just base station can determine: when PDCCH physical resource is Chong Die with the physical resource that synchronization signal block occupies, the user equipment is suitable It is (corresponding with the physical resource that synchronization signal block is overlapped including abandoning the PDCCH that conjunction directly abandons the PDCCH resource PDCCH is perhaps abandoned described in the search space corresponding with the physical resource that synchronization signal block is overlapped the PDCCH or discarding PDCCH monitoring opportunity corresponding with the physical resource that synchronization signal block is overlapped), or solution rate-matched decoding can be passed through PDCCH can punch decoding PDCCH.Later, the base station can determine according to the user capability of user equipment and be suitble to use The collision resolution at family.

In step s 102, if the PDCCH is Chong Die with the synchronization signal block resource, base station can at least be abandoned The resource lap of the PDCCH.Wherein, the resource lap of the PDCCH can be the PDCCH and synchronization signal The corresponding PDCCH of physical resource of block overlapping.

Preferably, before base station abandons the resource lap of the PDCCH, the base station can be according to user equipment Instruction is sent, described instruction is used to indicate the resource lap for the PDCCH that the user equipment at least abandons, Ye Jiru Fruit base station, which determines, abandons PDCCH, then described instruction instruction user equipment directly abandons the PDCCH；If the base station determine that abandoning PDCCH and through-rate matching way transmission PDCCH, then described instruction instruction user equipment is decoded using solution rate-matched mode PDCCH；If the base station determine that sending PDCCH using hole knockout, then described instruction instruction user equipment is decoded by tradition PDCCH Mode decodes the PDCCH.

As an alternate embodiment, Fig. 2 is the collision of a kind of PDCCH and synchronization signal block of second embodiment of the invention The flow diagram of solution.With reference to Fig. 2, the collision solution be may comprise steps of:

Step S201: judge whether resource is overlapped for PDCCH and synchronization signal block；

Step S202: when the PDCCH and the synchronization signal block resource are overlapped, the PDCCH and described same is abandoned Walk the corresponding PDCCH of physical resource of block overlapping.

Specifically, step S201 is first carried out in base station, namely judge whether resource is overlapped for PDCCH and synchronization signal block. Specifically, those skilled in the art can be with reference to step S101 described in above-mentioned embodiment illustrated in fig. 1, and it will not be described here.

Secondly step S202 is executed, if the object that physical resource and the synchronization signal block that the PDCCH is occupied occupy It is overlapped to manage resource, then, when the PDCCH and the synchronization signal block collide, base station can abandon the PDCCH with The corresponding PDCCH of physical resource of the synchronization signal block overlapping.Further, if the physical resource that the PDCCH is occupied The physical resource occupied with the synchronization signal block is not exclusively Chong Die (for example, the physics PDCCH Chong Die with synchronization signal block The size of resource corresponds to CCE or REG), the PDCCH can also be abandoned.

Specifically, with PDCCH CCE quantity corresponding with the size for the physical resource that synchronization signal block is overlapped be 3 and REG quantity is illustrated for being 4.As described in the background art, each PDCCH is made of one or more CCE, each CCE It is made of 6 REG.The quantity for forming the CCE of PDCCH is indicated by polymerization grade.Under the premise of herein, when polymerization grade indicates candidate When PDCCH is 4 CCE, even if the resource lap is that the PDCCH is corresponding with the physical resource that synchronization signal block is overlapped 3 CCE, the PDCCH can also be abandoned.Alternatively, even if the resource lap is the PDCCH and synchronization signal block Corresponding 3 REG of the physical resource of overlapping, can also abandon the PDCCH.As it can be seen that using the processing side for abandoning the PDCCH Formula can reduce the processing complexity of base station and user equipment.It should be noted that the quantity of the CCE and the quantity of REG can To be changed according to practical application scene.

As a preferred embodiment, if what physical resource and the synchronization signal block that the PDCCH is occupied occupied Physical resource is completely overlapped, then, base station, which may not need, executes the operations such as coding, modulation and mapping to the PDCCH, can lose Abandon the PDCCH.

As another alternate embodiment, Fig. 3 is a kind of PDCCH of third embodiment of the invention and touching for synchronization signal block Hit the flow diagram of solution.With reference to Fig. 3, the collision solution be may comprise steps of:

Step S301: judge whether resource is overlapped for PDCCH and synchronization signal block；

Step S302: when the PDCCH and the synchronization signal block resource are overlapped, the PDCCH and synchronous letter are abandoned The corresponding search space of physical resource of number block overlapping.

In specific implementation, step S301 is first carried out in base station, namely judge PDCCH and synchronization signal block whether resource weight It is folded.Specifically, those skilled in the art can be with reference to step S101 described in above-mentioned embodiment illustrated in fig. 1, and it will not be described here.

Secondly, execute step S302, when the PDCCH and the synchronization signal block resource are overlapped, abandon the PDCCH with The corresponding search space of physical resource of synchronization signal block overlapping.Described search space may include multiple candidate PDCCH.If Abandon described search space, then base station may not need multiple candidate PDCCH in described search space are encoded, modulate and Map operation.Compared to collision method technical solution shown in Fig. 2, collision solution shown in Fig. 3 is simpler, complexity more It is low.

As another alternate embodiment, Fig. 4 is a kind of PDCCH of fourth embodiment of the invention and touching for synchronization signal block Hit the flow diagram of solution.With reference to Fig. 4, the collision solution be may comprise steps of:

Step S401: judge whether resource is overlapped for PDCCH and synchronization signal block；

Step S402: when the PDCCH and the synchronization signal block resource are overlapped, the PDCCH and synchronous letter are abandoned The corresponding PDCCH of physical resource of number block overlapping monitors opportunity.

Specifically, step S401 is first carried out, namely judge whether resource is overlapped for PDCCH and synchronization signal block.Specifically Ground, those skilled in the art can be with reference to step S101 described in above-mentioned embodiment illustrated in fig. 1, and it will not be described here.

Secondly, step S402 is executed, as the PDCCH and synchronization signal block resource overlapping, base station (and user sets It is standby) the monitoring opportunity comprising PDCCH corresponding with the physical resource that synchronization signal block is overlapped can be abandoned.Wherein, the prison of PDCCH Survey opportunity includes multiple search spaces.For user equipment, once it is determined that the PDCCH and the overlapping of synchronization signal block resource, It can be after determining the resource lap corresponding PDCCH monitoring opportunity, ignoring PDCCH monitoring opportunity includes Search space carries out blind examination without carrying out PDCCH to multiple search spaces in the PDCCH monitoring opportunity.Compared to Fig. 2 and figure Solution is collided shown in 3, directly discarding PDCCH monitoring opportunity can further decrease base station and user equipment processing The complexity of PDCCH and synchronization signal block collision problem.

As another alternate embodiment, Fig. 5 is a kind of PDCCH of fifth embodiment of the invention and touching for synchronization signal block Hit the flow diagram of solution.With reference to Fig. 5, the collision solution be may comprise steps of:

Step S501: judge whether resource is overlapped for PDCCH and synchronization signal block；

Step S502: when the PDCCH and the synchronization signal block resource are overlapped, the money of the PDCCH is at least abandoned Source lap；

Step S503: by the coded bit of the PDCCH in the PDCCH in addition to the resource lap Other parts carry out rate-matched.

Specifically, step S501 is first carried out in base station, namely judge whether resource is overlapped for PDCCH and synchronization signal block. Secondly, executing step S502, namely abandon PDCCH PDCCH corresponding with the physical resource that the synchronization signal block is overlapped. Preferably, base station can receive wireless heterogeneous networks (Radio Resource Control, abbreviation RRC) signaling to user equipment First preset threshold of transmission.Specifically, those skilled in the art can be with reference to step described in above-mentioned embodiment illustrated in fig. 1 S101 and step, it will not be described here.

Later, step S503 is executed, as the PDCCH and synchronization signal block resource overlapping, if the PDCCH The physical resource of occupancy is only overlapped with the physical resource that the synchronization signal block occupies (for example, the PDCCH and synchronous The physical resource of block overlapping is 1 CCE or 1 REG), then, base station can execute coding behaviour to the PDCCH first Make to obtain the coded bit of the PDCCH；Secondly, physics of the coded bit of the PDCCH for non-overlap is provided Source carries out rate-matched.The physical resource of the non-overlap is the PDCCH physics money Chong Die with the synchronization signal block Remaining physical resource other than source.In the case, user equipment is in the object for determining candidate PDCCH and the overlapping of synchronization signal block After managing resource, rate-matched, the blind examination decoding PDCCH can be solved, so as to improve the resource utilization of PDCCH.

As an alternate embodiment, if the size of the physical resource PDCCH Chong Die with synchronization signal block is with REG It measures, then, base station can abandon the PDCCH first REG corresponding with the physical resource that the synchronization signal block is overlapped；So Remaining physical resource (namely remaining REG) of the coded bit of the PDCCH for the PDCCH is subjected to rate afterwards Match.Wherein, the remaining REG and REG of discarding belongs to the same PDCCH of same search space.

As an advantageous variant embodiment, if base station is learnt from the user capability information that user equipment is sent, when When the resource lap is less than the REG quantity of preset threshold, which can be decoded based on solution rate-matched mode The PDCCH, then the greatest measure (such as the first preset threshold) that base station can send the REG of discarding is connect with notifying user equipment Receive PDCCH.

Specifically, the size of the physical resource PDCCH Chong Die with synchronization signal block is measured with REG, then, base station is first The PDCCH can first be abandoned REG corresponding with the physical resource that the synchronization signal block is overlapped；Then, when the REG number of discarding Amount be less than preset threshold (for example, with the first preset threshold indicates abandon REG greatest measure) when, base station can will described in The coded bit of PDCCH carries out rate-matched for the remaining physical resource (namely remaining REG) of the PDCCH.Wherein, The remaining REG and REG of discarding belongs to the same PDCCH of same search space.

Preferably, the preset threshold can be sent to user equipment with described instruction together.Alternatively, the preset threshold A part as described instruction is sent to user equipment.

As another alternate embodiment, if the size of the physical resource PDCCH Chong Die with synchronization signal block with CCE is measured, then, it is corresponding with the physical resource that the synchronization signal block is overlapped that base station can abandon the PDCCH first CCE；Then remaining physical resource (namely remaining CCE) of the coded bit of the PDCCH for the PDCCH is carried out Rate-matched.Wherein, the remaining CCE and CCE of discarding belongs to the same PDCCH of same search space.

Correspondingly, user equipment is after determining the corresponding CCE of physical resource that candidate PDCCH and synchronization signal block are overlapped, Rate-matched, the blind examination decoding PDCCH can be solved, so as to improve the resource utilization of PDCCH.

As another advantageous variant embodiment, if base station is learnt from the user capability information that user equipment is sent, When the resource lap is less than the CCE quantity of preset threshold, which can be translated based on solution rate-matched mode The code PDCCH, then the preset threshold that base station can send the greatest measure of the CCE of discarding is received with notifying user equipment PDCCH。

In specific implementation, if the size of the physical resource PDCCH Chong Die with synchronization signal block is measured with CCE, that , base station can abandon the PDCCH first CCE corresponding with the physical resource that the synchronization signal block is overlapped；Then, when losing When the CCE quantity of abandoning is less than preset threshold (for example, the greatest measure for the CCE for indicating to abandon with the first preset threshold), base station can Remaining CCE of the coded bit of the PDCCH for the PDCCH is carried out rate-matched.Wherein, described remaining The CCE and CCE of discarding belongs to the same PDCCH of same search space.

For user equipment, user equipment, which can shift to an earlier date from base station, receives the preset threshold that RRC signaling is transmitted.Later, User equipment can determine candidate PDCCH based on polymerization grade, if the candidate PDCCH can be touched with synchronization signal block It hits, and the physical resource of the overlapping is less than preset threshold, then, user equipment can execute solution rate-matched, blind examination decoding The candidate PDCCH.

As another alternate embodiment, Fig. 6 is a kind of PDCCH of sixth embodiment of the invention and touching for synchronization signal block Hit the flow diagram of solution.With reference to Fig. 6, the collision solution be may comprise steps of:

Step S601: judge whether resource is overlapped for PDCCH and synchronization signal block；

Step S602: when the PDCCH and the synchronization signal block resource are overlapped, in the PDCCH of encoded modulation In, the physical resource Chong Die with the synchronization signal block is destroyed by the way of punching.

Step S601 is first carried out, namely judges whether resource is overlapped for PDCCH and synchronization signal block.Specifically, this field Technical staff can be with reference to step S101 described in above-mentioned embodiment illustrated in fig. 1, and it will not be described here.

Secondly, step S602 is executed, as the PDCCH and synchronization signal block resource overlapping, if the PDCCH The physical resource of occupancy is only overlapped with the physical resource that the synchronization signal block occupies (for example, the PDCCH and synchronous Less than 1 CCE of physical resource of block overlapping), then, base station can execute coding, modulation, mapping etc. to the PDCCH Operation.Later, in the PDCCH of encoded modulation, the object Chong Die with the synchronization signal block is destroyed by the way of punching Resource is managed, so that user equipment can be according to traditional PDCCH blinded fashion (namely when PDCCH and not be overlapped synchronization signal block The PDCCH blinded fashion of use) decoding PDCCH.It should be evident that for user equipment, collision solution shown in fig. 6 The complexity very little of technical solution can decode PDCCH based on the prior art of user equipment.

But, if the physical resource of overlapping is larger, biggish false detection rate and void may be brought by the way of punching Alert rate, thus, as a preferred embodiment, when the size of the physical resource PDCCH Chong Die with the synchronization signal block When can be measured using REG, base station can destroy the physical resource Chong Die with the synchronization signal block by the way of punching.

It specifically, is that the PDCCH is corresponding with the physical resource that the synchronization signal block is overlapped with the physical resource destroyed REG for, when the overlapping physical resource less than the second preset threshold (for example, with the second preset threshold instruction abandon The quantity of REG) when, base station can be destroyed and the synchronization signal in the PDCCH of encoded modulation by the way of punching The REG of block overlapping.For user equipment, in user equipment after the second preset threshold that base station receives that RRC signaling is transmitted, The user equipment (namely can be used still according to traditional PDCCH blinded fashion when PDCCH and not be overlapped synchronization signal block PDCCH blinded fashion) decoding PDCCH.

As an alternate embodiment, when the size of the physical resource PDCCH Chong Die with the synchronization signal block can When being measured using CCE, base station can also destroy the physical resource Chong Die with the synchronization signal block by the way of punching, this In repeat no more.

It should be noted that it will be appreciated by those skilled in the art that in practical applications, first preset threshold and described Two preset thresholds may be the same or different, and can change more embodiments out according to actual needs, it will not be described here.

Further, to avoid the PDCCH and the synchronization signal block resource from being overlapped, different PDCCH can also be used Resource distribution mode, for example, base station can pass through two kinds of PDCCH resource methods of salary distribution of RRC signaling notifying user equipment: the first For there is collision scene, second for collisionless scene.As PDCCH and synchronization signal block collision (namely resource overlapping), Using the first resource distribution mode (for example carrying PDCCH and synchronization signal block respectively using orthogonal resource)；As PDCCH and together When walking block collisionless (namely resource overlapping), using second of resource distribution mode (like skipping traditional PDCCH resource point Resource distribution mode with the PDCCH mode that resource overlapping may occur in mode).Different scenes are provided using different PDCCH The source method of salary distribution can bring less performance loss, but need biggish RRC signaling expense.

Fig. 7 is the process signal of a kind of PDCCH of seventh embodiment of the invention and the collision solution of synchronization signal block Figure.The collision solution can be used for user equipment side, can specifically include following steps:

Step S701: judge whether resource is overlapped for PDCCH and synchronization signal block；

Step S702: when the PDCCH and the synchronization signal block resource are overlapped, the money of the PDCCH is at least abandoned Source lap.

Specifically, in step s 701, user equipment is sent to user capability and reports information, the user capability is reported Information may include decoding rate-matched ability when user decodes PDCCH, and punching decoding capability, so that base station determines institute State the discarding mode of resource lap.

Further, user equipment can abandon the resource overlapping portion according to described instruction after receiving described instruction Point.For example, it is (corresponding with the physical resource that synchronization signal block is overlapped including abandoning the PDCCH directly to abandon the PDCCH resource PDCCH, perhaps abandon the search space corresponding with the physical resource that synchronization signal block is overlapped the PDCCH or discarding institute State PDCCH monitoring opportunity corresponding with the physical resource that synchronization signal block is overlapped), or solution rate-matched decoding can be passed through PDCCH, or decoding PDCCH can be punched.

In step S702, in user equipment blind examination PDCCH, user equipment also may determine that candidate PDCCH whether can It collides with synchronization signal block.When the PDCCH and the synchronization signal block resource are overlapped, the PDCCH is at least abandoned Resource lap.Wherein, the resource lap of the PDCCH can be Chong Die with synchronization signal block for the PDCCH The corresponding PDCCH of physical resource.

Alternatively, abandoning the PDCCH and synchronization signal block weight when the PDCCH and the synchronization signal block resource are overlapped The corresponding search space of folded physical resource.That is, user equipment can be searched the physical resource for determining the overlapping is corresponding After rope space, without carrying out blind examination to PDCCH in described search space.

Or user equipment can abandon the prison comprising PDCCH corresponding with the physical resource that synchronization signal block is overlapped Survey opportunity.That is, user equipment ignores the PDCCH after determining the resource lap corresponding PDCCH monitoring opportunity The search space that monitoring opportunity includes, it is blind without carrying out PDCCH progress to multiple search spaces in the PDCCH monitoring opportunity Inspection.

As a non-limiting embodiment, before carrying out solution rate-matched and decoding the candidate PDCCH, the user Equipment, which can shift to an earlier date from base station, receives the first preset threshold that RRC signaling is transmitted.Wherein, first preset threshold can indicate The greatest measure of the REG or CCE of discarding.

Further, user equipment can be in the corresponding REG of physical resource for determining candidate PDCCH and the overlapping of synchronization signal block Or after CCE, rate-matched, the blind examination decoding PDCCH can be solved, so as to improve the resource utilization of PDCCH.

Later, user equipment can determine candidate PDCCH based on polymerization grade, if the candidate PDCCH believes with synchronous Number block can collide, and the physical resource of the overlapping is less than the preset threshold, then, user equipment can solve rate Match, blind examination decodes the candidate PDCCH.

As another alternate embodiment, if base station is beaten by the way of punching in the PDCCH of encoded modulation Fall the physical resource Chong Die with the synchronization signal block, so as to user equipment can according to traditional PDCCH blinded fashion (namely The PDCCH blinded fashion that PDCCH and when not be overlapped synchronization signal block use) decoding PDCCH.

Preferably, in user equipment after the second preset threshold that base station receives that RRC signaling is transmitted, the user equipment It can be still according to (namely the PDCCH blind examination used when PDCCH and not be overlapped synchronization signal block of traditional PDCCH blinded fashion Mode) decoding PDCCH.
