Detailed Description
The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In this embodiment, a resource allocation method operating in a base station is provided, and fig. 1 is a flowchart of resource allocation according to an embodiment of the present disclosure, as shown in fig. 1, the flowchart includes the following steps:
step S102, a base station configures a plurality of sets of resources for UE;
step S104, the base station indicates at least one of the following information through signaling: the offset between the multiple sets of resources, the maximum number of configured resource sets, and the maximum number of simultaneously activated resource sets;
and step S106, the base station issues an instruction to activate or deactivate the plurality of sets of resources.
In step S102 of this embodiment, the base station may configure different scheduling-free resource sets for the UE, where resources in the different resource sets correspond to different QoS service requirements of the UE. One or more sets of scheduling-free resources can be configured in the same resource set, and if multiple sets of resources are configured, the time domain size, the frequency domain size, the MCS and other parameters of the multiple sets of resources are configured the same.
In step S104 of this embodiment, an offset may be configured among the sets of resources, and the offset may be implemented by one or a combination of more than one of the following: in mode 1, there is a time domain offset between different resources, and the size of the time domain offset may be one or more slots, symbols, the length of one or more PUSCHs, and the like, and may be configured by RRC signaling. Mode 2, there is a frequency domain offset between different resources, the size of the frequency domain offset may be one or N RBs, and the bandwidth is M times smaller (M, N are positive integers) and may be configured by RRC signaling. In mode 3, different resources are offset in time-frequency domain, and the granularity of the offset in time-frequency domain may be configured by RRC as described in modes 1 and 2.
The offset between the multiple sets of resources may be offset based on the first set of resources, for example, four sets of resources are configured, the time domain starting position of the first set of resources is 1, the configured time domain offset is 1, then the starting position of the second set of resources is 2, the starting position of the third set of resources is 3, and the starting position of the fourth set of resources is 4. Similar for other offsets, again without recitation.
In step S106 of the embodiment, if the offset manner of the multiple sets of resources is one, the signaling issued by the base station activates or deactivates the multiple sets of resources at the same time. And if the offset modes of the multiple sets of resources are multiple, simultaneously activating or deactivating the multiple sets of resources by a signaling sent by the base station, wherein the signaling comprises an indication domain for indicating the offset modes of the multiple sets of resources, or distinguishing the offset modes of the multiple sets of resources through different RNTIs or scrambling.
In the above embodiment, the signaling sent by the base station further includes an indication field for activating or deactivating the multiple sets of resources, where the indication field for activating or deactivating the multiple sets of resources adopts a bitmap manner. Each bit of the bitmap may correspond to a set of resources. Or the multiple sets of resources are divided into multiple groups, and 1bit in the bitmap can correspond to one set of resources.
In the foregoing embodiment, the base station uses 2 signaling joint indications to activate or deactivate the multiple sets of resources, where a first signaling corresponds to N1 sets of resources in the multiple sets of resources, and a second signaling corresponds to N2 sets of resources in the multiple sets of resources, where N1 and N2 are both positive integers. The first signaling can be a first type of signaling, the second signaling is a second similar instruction, the first type of instruction is configured by RRC, and the second similar signaling is configured by DCI scrambled by C-RNTI. The base station may indicate activation or deactivation of the plurality of sets of resources by mixing the first type signaling and the second type signaling.
In the above embodiment, if the resources activated by the first type signaling and the second type signaling are overlapped on the frequency domain, the resource activated by the first signaling is deactivated and the resource activated by the second signaling is effective in the first signaling and the second signaling. And if the resources activated by the first type signaling and the second type signaling are not overlapped on a frequency domain, and the number of the resource sets activated by the first type signaling and the second type signaling is less than or equal to the maximum number of the resource sets which are configured and activated at the same time, the resources activated by the first type signaling and the second type signaling are effective. If the resources activated by the first type signaling and the second type signaling are not overlapped on the frequency domain, and the number of the resource sets activated by the first type signaling and the second type signaling is greater than the maximum number of the resource sets activated at the same time, the resources activated by the signaling sent first in the first type signaling and the second type signaling are deactivated, and the resources activated by the signaling sent later are effective.
In the above embodiment, the UE selects resources from the same set or multiple sets of resources activated by one signaling at the same time for service transmission; or, the UE selects a resource with the minimum delay for service transmission, or the UE preferentially selects a resource shifted in the frequency domain at the same time, and if there is no frequency domain shifted resource satisfying the condition, the UE selects a resource shifted in the time domain again.
The following describes, by way of specific embodiments, a plurality of sets of resource configurations and activations in the following scenarios: scenario 1) the same UE has multiple QoS service requirements; scenario 2) supporting the reliability and the time delay performance of the same service of the same UE; scenario 3) supports avoiding resource collision between UEs in an Inter-UE multiplexing scenario.
Examples 1 to 1
In this embodiment, the base station configures different resource sets for the UE, where resources in the different resource sets correspond to different QoS service requirements of the UE. One or more sets of resources can be configured in the same resource set, and if multiple sets of resources are configured, parameters such as time domain size, frequency domain size, MCS and the like of the multiple sets of resources are configured to be the same size. An offset can be configured among the multiple sets of resources, and the offset can be in a mode of combining one or more of the following: in mode 1, there is a time domain offset between different resources, and the size of the time domain offset may be one or more slots, symbols, the length of one or more PUSCHs, and the like, and may be configured by RRC signaling. Mode 2, there is a frequency domain offset between different resources, the size of the frequency domain offset may be one or N RBs, and the bandwidth is M times smaller (M, N are positive integers) and may be configured by RRC signaling. In mode 3, different resources are offset in time-frequency domain, and the granularity of the offset in time-frequency domain may be configured by RRC as described in modes 1 and 2.
When a base station configures the number N (N is a positive integer) of simultaneously activated resource sets for UE, if the offset mode of the multiple sets of resources is only one, activated signaling (Type1 or Type2, Type1 is configured and activated by RRC; Type2 is activated by DCI scrambled by CS-RNTI) issued by the gNB simultaneously activates the multiple sets of resource configurations; if the offset mode of multiple sets of resources is configured with multiple types (2 types correspond to 1-bit indications and 3 types correspond to 2-bit indications), the activation signaling issued by the gNB activates multiple sets of resources at the same time, and the activation signaling contains an offset indication field (a new bit field can be introduced in Type1, and a low bit or RV indication field of a HARQprocess ID field can be reused in Type 2) used for indicating the activated multiple sets of resources to adopt or distinguishes different offset modes through different RNTIs and scrambling.
Then activated by activation signaling, wherein the activation signaling can be RRC signaling (Type1), DCI signaling scrambled by CS-RNTI or L1 signaling activation, and the structure of MAC-CE signaling, MAC-CE signaling and DCI signaling structure scrambled by CS-RNTI can be the same.
Correspondingly, multiple sets of resource configurations activated simultaneously are also deactivated simultaneously when deactivated (the same applies to the following embodiments, which are not described again)
As shown in fig. 2, the number of sets of resources configured to be activated simultaneously in the resource set 1 is 4, and a plurality of sets of resources employ time domain offset (offset method 1). The number of sets of resources configured to be activated simultaneously in the set 2 is 2, and a plurality of sets of resources adopt frequency domain offset (offset mode 2). The number of configured simultaneous activation sets in the resource set 3 is 1 without offset.
In one embodiment of the present disclosure, a Group DCI is used to indicate a plurality of sets of resources, and a plurality of bit fields are provided in the Group DCI, and the plurality of bit fields can independently configure and activate the plurality of sets of resources.

For scenario 1), the same UE supports multiple service requirements of different QoS, and the base station activates the N sets of resource configurations using N RRC signaling or N DCI signaling according to the number N of different QoS services supported by the user.
Aiming at the scene 2), the reliability and the time delay performance of the same service supported by the same UE are ensured, the multiple sets of resources meet the same service at the moment, the parameters of the multiple sets of resource configuration are the same, a base station indicates the offset (including time domain offset or time-frequency domain offset, and offset granularity refers to the embodiment 1-1) between the multiple sets of services and the number N of simultaneously activated resource sets through signaling (RRC), the activation signaling issued by the gNB activates the multiple sets of resource configuration at the same time, if the offset mode is multiple, the activation signaling comprises an offset indication domain used for indicating the activated multiple sets of resources to adopt or distinguishes different offset modes through different RNTIs and scrambling;
for scenario 3), collision between UEs in Inter-UE multiplexing is avoided, parameters of multiple sets of resource configurations are the same, a base station indicates, through signaling (RRC), offset (including frequency domain offset or both time and frequency domain offset, and offset granularity refers to embodiment 1-1) between multiple sets of services and the number N of resource sets to be activated at the same time, an activation signaling issued by a gNB activates multiple sets of resource configurations at the same time, and if there are multiple offset modes, the activation signaling includes an offset indication field used for indicating the activated multiple sets of resources to use, or distinguishes different offset modes through different RNTIs and scrambling.
Examples 1 to 3
In this embodiment, when configuring resources for the UE, the base station distinguishes different scenarios supported by the UE, and the resources are configured independently in different scenarios.
For scenario 1), the same UE supports multiple service requirements of different QoS, and the base station activates the N sets of resource configurations by using N RRC signaling or N DCI signaling or N RRC and DCI signaling according to the number N of different QoS services supported by the user;
for scenario 2), the reliability and the delay performance of the same service supported by the same UE are guaranteed, at this time, multiple sets of resources all satisfy the same service, the parameters of the multiple sets of resources are the same, the base station indicates, through signaling (RRC), the offset (including time domain offset, or both time and frequency domain offset, and offset granularity refer to example 1-1) between the multiple sets of services and the maximum number N of sets of resources to be configured, an activation signaling issued by the gNB includes an indication field for indicating the offset manner of the multiple sets of resources (or distinguishes different offset manners through different RNTIs and scrambling), and an indication field for activating the multiple sets of resources, and the indication field for activating the multiple sets of resources adopts a bitmap manner. Each bit from high to low (low to high) corresponds to a set of resource allocation in turn.
In a preferred embodiment, if the number of indication fields bit for activating multiple sets of resources included in the activation signaling is not enough, 2 signaling can be used to jointly indicate to activate multiple sets of resources, wherein the former DCI corresponds to the former N sets of resources, and the latter DCI corresponds to the latter N sets of resources;
in one embodiment, the gNB configures a resource group, the group includes N sets of resources, and 1bit in the bitmap in the activation signaling activates the N sets of resources at the same time.
For scenario 3), collision between UEs in Inter-UE multiplexing is avoided, parameters of multiple sets of resource configuration are the same, the base station indicates, through signaling (RRC), offsets (including frequency domain offset or both time and frequency domain offset, and offset granularity refers to embodiment 1-1) between multiple sets of services and a maximum number N of sets of resource configurations, an activation signaling sent by the gNB includes an indication field for indicating offset modes of multiple sets of resources (or different offset modes are distinguished through different RNTIs and scrambling), and an indication field for activating multiple sets of resources, where the indication field for activating multiple sets of resources adopts a bitmap mode. The high order to the low order (low order to high order) corresponds to a set of resource allocation.
In an embodiment, if the number of indication fields bit for activating multiple sets of resources included in the activation signaling is not enough, 2 joint indications can be used to activate the multiple sets of resources, where a previous DCI corresponds to the previous N sets of resources and a subsequent DCI corresponds to the subsequent N sets of resources;
in one embodiment, the gNB configures a resource group, the group includes N sets of resources, and 1bit in the bitmap in the activation signaling activates the N sets of resources at the same time.
Examples 1 to 4
In this embodiment, when configuring resources for the UE, the base station does not distinguish different scenarios supported by the UE, the base station indicates the maximum configured resource set number N and the time-frequency resource size to the UE, and configures the same resource configuration offset manner for parameters such as MCS, etc., an indication field (bitmap) for activation including an offset manner indication field and multiple sets of resources is the same signaling, and if the activated indication information does not include an offset manner indication field (or distinguishes different offset manners by different RNTIs and scrambling) and an indication field (bitmap) for multiple sets of resources, only one set of resources is configured and activated.
Example 2
In this embodiment, the base station indicates to the UE that the same signaling can simultaneously activate the maximum number N of resource sets and the size of time-frequency resources, the resource allocation offset manner that is the same as the MCS, the activation of multiple sets of resources is indicated by the mixture of Type1 and Type2, and the two types of configuration manners of Type1 and Type2 can exist simultaneously. The two can be implicitly deactivated, if the resource activated at the later moment is overlapped with the frequency domain resource activated in the front, the resource activated later takes effect, and the resource activated before is deactivated. When the same signaling activates multiple sets of resources, the signaling contains an offset mode indication domain and a bit domain for indicating the multiple sets of resources, and the multiple sets of resources are indicated in a bitmap form. For example, after a certain set (multiple sets, as in the case of multiple sets of resource configurations in the series of embodiment 1) is activated by Type1, then Type2 also activates one or more sets of resources and the frequency domain resources partially overlap with the frequency domain resources configured by Type1, so that the resources configured by corresponding Type1 are deactivated.
In this embodiment, if a plurality of sets of resources are configured and activated simultaneously by two front and back signaling (one signaling simultaneously activates a plurality of sets of resources, and the signaling includes a corresponding plurality of sets of resource indication fields and an offset mode indication field), if the number of sets of resources simultaneously activated in the two front and back signaling is less than or equal to the maximum number N of sets of resources configured and simultaneously activated, the resources activated by the two signaling are all in effect, and bit fields in the two front and back signaling are taken together as an activated resource bit field, and sequentially correspond to 1 to M sets of resources from high order to low order, as shown in fig. 3.
In this embodiment, if the number of resource sets simultaneously activated in the two signaling before and after is greater than the maximum number N of resource configuration sets configured to be simultaneously activated, the resource activated later becomes effective, and the resource activated earlier is deactivated.
Example 3
In this embodiment, the base station configures multiple sets of scheduling-free resources for the UE, and the UE in different scenarios has different requirements for the configured resources. The user may select different resource sets or different PUSCHs (PUSCH IDs for differentiation) according to requirements for service transmission, or the user may select different resource sets or different PUSCHs (PUSCH IDs for differentiation) according to logical channels, where one logical channel corresponds to one or more PUSCHs. For application scenarios 2) and 3), the user can only select appropriate resources for data transmission in the same set or in multiple sets of resource allocations activated by one signaling at the same time. For scenario 2), the user selects the resource with the smallest delay (closest to it) for service transmission, and for scenario 3), the user preferentially selects the resource shifted in the frequency domain at the same time, and if there is no suitable frequency domain shift resource, the user selects the resource shifted in the time domain.
