Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, in particular to an enhanced mobile broadband (eMBB) control channel element (CCE) resource allocation method and device. BACKGROUND

[0002] Ultra reliable low latency communication (uRLLC) of new radio (NR) is a high-reliability, low-latency network slice service, which has higher priority than eMBB. In terms of scheduling timing, the time processing granularity of eMBB is a slot and that of uRLLC is a mini-slot. For the same air interface time, once uRLLC and eMBB downlink concurrent scheduling of a cell occurs, RB resource conflict occurs, uRLLC punches the downlink control channel allocated by eMBB in a pre-emptive manner to ensure high-priority transmission of uRLLC, but the punching of the downlink control channel of uRLLC on eMBB will affect the transmission of eMBB.

[0033] Hereinafter, the present application will be described in detail with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0034] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0035] For the scenario of NR uRLLC network slice and eMBB slice cooperative scheduling, in order to reduce the impact of resource puncturing on eMBB under the premise of guaranteeing uRLLC high priority processing, an eMBB CCE resource allocation method is provided in an embodiment of the present application.

[0036] Figure 1 is a flow chart of the eMBB CCE resource allocation method according to an embodiment of the present application, as shown in Figure 1 , the flow includes the following steps:

[0037] In step S102, when eMBB CCE resource allocation is performed, if the required CCE resource can be allocated within the RB resource occupied by the currently allocated CCE, the required CCE resource is allocated within the RB resource.

[0038] Before step S102 of the present embodiment, it can also include: judging whether the required CCE resource can be allocated within the RB resource occupied by the currently allocated CCE.

[0039] In step S102 of the embodiment, if the required CCE resource cannot be allocated within the RB resource occupied by the currently allocated CCE, the required CCE resource is allocated next to the edge of the RB or the corresponding CORESET occupied by the PDCCH in the direction from low to high or from high to low.

[0040] After step S102 of the embodiment, the eMBB scheduler can further include the following steps: counting the uRLLC scheduling RB usage rate; and if the uRLLC RB usage rate reaches a threshold value more than n times within a preset time length, the eMBB scheduler controls the CCE resource allocation in the subsequent z slots, where n and z are positive integers.

[0041] In the embodiment, the eMBB scheduler controlling the CCE resource allocation in the subsequent z slots includes the following steps: determining whether the number of RBs occupied by the allocated PDCCH reaches k, and if so, no CCE resource allocation is performed in the subsequent z slots, where k is a positive integer.

[0042] In the embodiment, the eMBB scheduler controlling the CCE resource allocation in the subsequent z slots can further include the following steps: or determining whether the CCE aggregation degree of the currently scheduled user reaches a threshold value, and if so, no CCE resource allocation is performed in the subsequent z slots.

[0043] In the embodiment, the following steps can be further included: through the interaction channel established between the eMBB and the uRLLC, the eMBB notifies the uRLLC of the PDCCH resource allocation result at the downlink scheduling moment corresponding to the air interface Minislot 0, where the allocation result includes the air interface time and the RB resource set occupied by the PDCCH, and the uRLLC only allocates resources on the RBs without eMBB PDCCH resource occupation within its BWP bandwidth when performing downlink RB resource allocation, and sends the PDSCH RB occupation condition to the eMBB.

[0044] In the embodiment, for the scenario that the DMRS configuration of the uRLLC is on the first symbol of each Minislot, and the first symbol is the PDCCH of the eMBB, the following steps can be included: determining whether there is a uRLLC downlink air interface data transmission to the scheduled user within the RB resource range occupied by the eMBB PDCCH in the previous t Minislots of the current Minislot 0; and if so, buffering the DMRS corresponding to the PDSCH closest to the Minislot 0 in the t Minislots at the UE side, for demodulating the single-symbol PDSCH without DMRS transmitted by the base station on the RB of the PDSCH.

[0045] In the embodiment, the DMRS configuration for uRLLC is on the first symbol of each Minislot, and the first symbol is for the PDCCH of eMBB. The method further includes the following steps: determining whether the base station has uRLLC downlink air interface data for the scheduled user within the RB resource occupied by the eMBB PDCCH in the first t Minislots; and if yes, the base station transmits a single-symbol PDSCH without DMRS on the RB resource on which the PDSCH is previously transmitted.

[0046] In the embodiment, the influence of uRLLC on the eMBB control channel is avoided by the downlink RB scheduling avoidance and DMRS effective time extension strategy, and the uRLLC service rate is guaranteed as much as possible.

[0047] In order to facilitate the understanding of the technical solutions provided by the embodiments of the present application, the following will be described in detail with reference to the embodiments with application scenarios.

[0048] Figure 2 For the wireless resource configuration scenario according to the embodiment of the present application, as shown in FIG. 1, the Minislot resource configuration of eMBB PDCCH is that 2 OFDM symbols constitute 1 Minislot, and 14 symbols in 1 slot are cut into 7 Minislots in the uRLLC scheduling timing, and the first symbol of Minislot 0 is eMBB PDCCH. Figure 1

[0049] If the uRLLC data transmission PDSCH and the RB position of the eMBB occupied PDCCH conflict in the Minislot configured with the eMBB PDCCH, the PDSCH of uRLLC will puncture the PDCCH of eMBB, which may cause the UE down control information (DCI) detection failure, thereby causing the eMBB transmission loss and HARQ state abnormality. The control channel is punctured, which is more serious than the data channel puncture, and should be avoided as much as possible.

[0050] More particularly, in the above case, if the DMRS configuration of uRLLC is on the first symbol of each Minislot, the second symbol on Minislot 0 cannot be used to transmit the uRLLC downlink data due to the presence of DMRS, because the UE needs to demodulate by means of DMRS, and the transmission of PDSCH is accompanied by the transmission of DMRS on the configured first symbol, which will also cause the eMBB PDCCH to be punctured.

[0051] ​The simplest solution to the above situation is to not schedule in Minislot 0 or to configure eMBB and uRLLC frequency division cell bandwidth, and to prevent resource conflict in a semi-static isolation manner. The former will cause the absence of Minislot 0 scheduling, causing the key latency of uRLLC to rise and the traffic to decrease; the latter will cause the available bandwidth of uRLLC to decrease, packet fragmentation, increased latency, and decreased traffic.

[0052] To solve the eMBB transmission problem caused by the punching of eMBB PDCCH resources by the radio air interface resources (including PDSCH and DMRS) occupied by uRLLC bearers in the Minislot configured with eMBB PDCCH, a scheduling strategy is provided in the embodiment to solve the above problem. The scheduling strategy mainly includes the following three aspects:

[0053] Strategy 1: In order to realize scheduling avoidance between the RBs occupied by eMBB PDCCH and the RBs occupied by uRLLC PDSCH, special processing is required for eMBB CCE resource allocation, and the CCE resource allocation should be as concentrated as possible. In order to ensure high-priority transmission of uRLLC, eMBB CCE resource usage should also be conservative.

[0054] As shown in Figure 3 , strategy 1 can use the following steps to make the allocated PDCCH resources as concentrated as possible:

[0055] Step S301, scheduling users for eMBB CCE resource allocation;

[0056] Step S302, determine whether the required CCE resources can be allocated within the RB resources occupied by the currently allocated CCEs. If the CCE resources can be allocated within the RB resources occupied by the currently allocated CCEs, step S303 is performed, and if the CCE resources cannot be allocated, step S304 is performed;

[0057] Step S303, allocate CCEs to the RB resource range to realize PDCCH resource concentration;

[0058] Step S304, determine whether other CCE resources have been allocated. If yes, step S305 is performed, and if no, step S306 is performed;

[0059] Step S305, allocate resources in the direction of adjacent PDCCH occupied RBs from low to high or from high to low to realize PDCCH resource concentration;

[0060] Step S306, allocate resources from the edge of the CORESET in the direction of adjacent PDCCH occupied RBs from low to high or from high to low to realize PDCCH resource concentration.

[0061] As Figure 4 shown, strategy 1 can further include the following steps:

[0062] Step S401, in the QoS of the eMBB scheduler, increase the counter of uRLLC scheduling RB usage, let m be the uRLLC RB usage threshold, and let n be the threshold of the number of times that the uRLLC scheduling RB exceeds m within the statistical sliding window t. Within the sliding window t, count the number of times that the uRLLC RB usage exceeds the threshold.

[0063] Step S402, determine whether the uRLLC RB usage exceeds the threshold m n times within the sliding window t. If yes, it is considered that the current is a heavy load period of uRLLC service, and step S403 is executed. If no, step S407 is executed.

[0064] Step S403, the eMBB scheduler adopts the strategy of limiting CCE resource allocation within the subsequent z slots.

[0065] Step S404, determine whether the number of RBs occupied by the PDCCH that has been allocated reaches k. If yes, step S406 is executed. If no, step S405 is executed.

[0066] Step S405, determine whether the CCE aggregation degree of the current user to be scheduled exceeds j. If yes, step S406 is executed. If no, step S407 is executed.

[0067] Step S406, the eMBB scheduler does not allocate CCE resources within the subsequent z slots, and gives up the eMBB users with poor channel conditions within this period.

[0068] Step S407, the eMBB scheduler normally allocates CCE resources.

[0069] In this embodiment, m, n, t, z, k, and j are all configurable parameters.

[0070] Through the above strategy 1, the eMBB CCE resource allocation is more intensive or limited, and more RB resources are reserved for uRLLC, thereby maximizing the guarantee of uRLLC high-priority transmission.

[0071] Policy 2: Through the interaction channel established between eMBB and uRLLC, at the downlink scheduling moment corresponding to air interface Minislot 0, eMBB notifies uRLLC of the PDCCH channel resource allocation result, and the notification content mainly includes air interface time and PDCCH occupied RB resource set. When performing downlink RB resource allocation, uRLLC actively avoids the RB occupied by eMBB PDCCH and only uses the RB in the BWP bandwidth that is not occupied by eMBB PDCCH resource. At the same time, uRLLC needs to send the situation of the PDSCH RB occupied by the side to eMBB to complete the statistics in step S401 of policy 1.

[0072] Policy 3: The DMRS configuration of uRLLC is on the first symbol of each Minislot, and the first symbol is the common configuration of eMBB PDCCH, such as Figure 2 After completing the scheduling policies 1 and 2 on Minislot 0, the uRLLC PDSCH and eMBB PDCCH have no RB overlap, and there is no uRLLC puncturing eMBB PDCCH. At this time, the second symbol of the RB occupied by eMBB PDCCH is silent. In order to make uRLLC use this part of air interface resource, policy 3 does the following processing:

[0073] Processing 1: If there is uRLLC downlink air interface data transmission to this user within the RB resource range occupied by eMBB PDCCH in the previous t Minislots of the current Minislot 0, the UE side caches the DMRS corresponding to the PDSCH closest to Minislot 0 in the t Minislots, for demodulating the single-symbol PDSCH without DMRS that Minislot 0 base station may send on these RBs.

[0074] Processing 2: If there is uRLLC downlink air interface data transmission to this user within the RB resource range occupied by eMBB PDCCH in the previous t Minislots of the current Minislot 0, the base station can send single-symbol PDSCH without DMRS on these RB resources on which PDSCH has been sent before.

[0075] As shown in Figure 5 Minislot 5 / 6 are both scheduled, and the UE caches the DMRS closest to Minislot 0, that is, the DMRS of Minislot 6 is used to demodulate the uRLLC PDSCH of Minislot 0, wherein the scheduling RB of Minislot 5 / 6 overlaps with the scheduling RB of Minislot 0.

[0076] In policy 3, the time stability of the channel is utilized. As shown inFigure 5 As shown, t in processes 1 and 2 can be configured, but for reliability, t should not be set too large, and should be less than the distance between the additional DMRS in front of the DMRS in the protocol to the earliest position. Such processing enables RB resources occupied by eMBB PDCCH on Minislot 0 to also be fully utilized, especially when the uRLLC bearer is in high-load operation, and there is a high probability that the preceding Minislot of Minislot 0 is scheduled, so that in Minislot 0, an effective transmission of uRLLC can be formed, thereby reducing the latency, improving the traffic, and without affecting the control channel of eMBB.

[0077] It should be noted that in the present embodiment, the above-mentioned strategies 1 to 3 can be used alone or in combination according to the actual scene.

[0078] In the present embodiment, by using the above-mentioned scheduling strategy, the service exception caused by the preemption of the uRLLC to the eMBB control channel is avoided, and the configurable DMRS effective strategy is adopted to make the uRLLC utilize the wireless resources as much as possible without affecting the eMBB, thereby improving the uRLLC downlink throughput.

[0079] In the above-mentioned embodiments of the present application, the present scheme adopts the special CCE allocation algorithm of eMBB and the targeted RB allocation algorithm of uRLLC, and through the cooperative interaction of uRLLC and eMBB, the overlapping of the downlink RB resources is avoided, and a strategy of extending the effective period of the DMRS is further adopted to realize the effective utilization of the air interface resources, which can effectively reduce the influence caused by the preemption of the uRLLC to the eMBB control channel resources, and improve the latency response and effective bandwidth capacity of the uRLLC, thereby optimizing the user experience of the uRLLC.
